Improved clamp and aids for lifting patients using the clamp
SCOPE OF THE INVENTION
The present invention relates to a clamp in an assembly with a rod and a belt, the belt being able to fix the position of the clamp relative to the rod when a load is suspended from the belt. More particularly, the invention relates to the processing of such an assembly in a device for lifting a patient with a physical disability, such as from a bed or a swimming pool, and in a device for assisting in repositioning a patient in a bed. The invention also relates to a method for manufacturing such an assembly.
BACKGROUND OF THE INVENTION
Lifting systems for moving people form an important part of the equipment in, for example, private homes, group homes, swimming pools, a hospital or a nursing home. They make it possible to move fully or partially immobile patients or residents between their bed, wheelchair, toilet, bath, swimming pool, or other place of residence, without the nursing assistants having to perform heavy manual tilar work.
Lifting systems of this type often consist of an overhead rail system with a carrying cage provided with a lifting motor or device or a lifting device that allows horizontal and vertical movement, and a system for supporting the body suspended from the carriage or carrying cage, lifting device or lifting device, which makes it possible to support the patient's body during its movement. Typically, a body support or harness is provided to the person, and the body support is connected to the lifting system, usually via a connection.
The lifting system is provided with one or more motors for performing the vertical movement. Moreover, the carriage can be connected to one or more motors that perform the horizontal movement. Alternatively, horizontal and / or vertical movement can be performed manually by a nursing assistant that pushes against the lifting system or the person to be moved. Alternatively, instead of being mounted on the ceiling, the lifting system may be mounted on a mobile unit with wheels underneath, or mounted against a wall. This allows the patient to be moved independently of a fixed overhead rail system.
The operation of the various functions can be carried out by the nursing assistant or by the person himself via a control on the lifting system or via a portable control unit.
Examples of such lifting systems are known from US 2006/0002252 or US 6,523,195.
With all these systems, it is important that the belt is securely attached to the body support in such a way that the release of the person to be lifted is prevented. This is accomplished with a coupling provided between the belt and the body support, or directly on the frame of the lifting system. US 2005/0000016 A1 describes a device for lifting a patient comprising two arms, a cup-shaped structure being arranged on each arm. The cup-shaped structures are provided for gripping the patient on either side of the patient's chest and are shaped accordingly. To improve the comfort of the patient, each arm of the lifting device is preferably provided with a leg support on which the legs of the patient can be carried. In this way, the gripping force exerted on the patient's chest is improved, since the weight of the legs rests directly on the arms of the patient lifting device. Each leg support is suspended from one of the arms of the patient lifting device with a belt, this belt being passed through an opening in the head of the leg support, directly around the arm or around a sliding element provided around the arm , is wound, and both ends of the belt are fastened in a buckle that makes it possible to adjust the length of the belt.
For various reasons, the arms of the device for lifting a patient are provided with smooth surfaces. Suspending the leg supports in this way on the arms of the patient lifting device entails the disadvantage that the belts can move longitudinally along the smooth surface of the arms and / or can move across the arms. while the patient is being lifted. By moving the straps relative to the arms, the position of the leg supports can change, and therefore also the position of the patient in the lifting device, which is not desirable, because an important purpose of the lifting device is to keep the patient in a stable position during the lifting process. A position change involves the risk of the patient getting into an uncomfortable position, and possibly changing his position away from the desired sitting position, ie with the body and thighs bent at an angle of 90 °, and consequently the risk that the patient patient loses confidence in the institution.
Hospital beds are generally provided with an overhead trapeze, a device intended to help a patient reposition himself in the bed, or to help the patient get in and out of the bed. The position of the trapeze relative to the position of the patient in the bed (lower in the bed, higher in the bed ...) should preferably be adjustable both in the horizontal direction and in the vertical direction for the patient. The upper trapeze comprises a handle or handle suspended with a strap or chain on an upper bar or a sliding element around the upper bar, whereby the upper bar usually extends over the entire length or part of the length of the bed. extends, preferably centrally, with respect to the width of the bed. Pulling the handle allows the patient to lift his / her upper body and to change his / her position on the bed, or allows the patient to step in or out of the bed. The position of the handle above the patient can be changed by adjusting the length of the belt or chain, and / or by moving the belt, chain or sliding element axially along the longitudinal axis of the overlying bar. In the case that a chain is used to suspend the handle from the upper bar, the length of the chain can be adjusted by a hook provided in the head of the handle by one of more of the links of the handle to place a chain. In the case that a strap is used to suspend the handle from the upper bar, the length of the strap can be adjusted with a buckle or with an adjustment tool provided on the handle as set forth in DE 20 2008 011 503 U1 .
Suspending the belt in this manner from the upper rod or the sliding element entails the disadvantage that the belt, the chain or the sliding element can move along the smooth surface of the upper rod, and that the position of the handle can change while the patient is changing his / her position in the bed, or while he / she is getting in or out of the bed, which can cause the patient to fall back into the bed in an uncomfortable way position, can cause the patient to get hurt, or even cause the patient to fall out of bed. One solution is to attach the sliding element to the upper rod with a screw through the side of the sliding element that presses against the surface of the upper rod. This requires loosening and tightening screws every time the position of the sliding element along the upper bar is to be changed, an operation that is time-consuming and where there is still a risk that the screw will not be screwed tightly enough, so that the sliding element can still move along the upper bar, and whereby the smooth surface of the upper bar can be damaged. DE 219687 C describes a clamping device for suspending the handle or handle of an upper trapeze on an upper bar (g) of a hospital bed by means of a belt or chain. The clamping device is configured to clamp on the upper bar when a patient pulls the strap or chain from the handle or handle such that it is prevented from moving along the upper bar. The clamping device comprises two tongs (a and b) that are connected to each other at one end by means of a hinge (c). At the opposite ends the tong-shaped bars are provided with eyes that are connected to each other by means of a cord or chain (d). A ring (f) hangs from this cord or chain on which the handle or handle is suspended by means of a belt or chain. A tensile force on the handle or handle (e) is transmitted via the connecting belt or chain and the ring to the cord or chain connecting the eyes on the tongs. The force pulls the pincer-shaped bars together, so that the clamping device is clamped onto the upper bar.
A drawback of such a clamping device is that certain parts of the device are subjected to great forces when a load is suspended from it. These forces can be much stronger than the weight of the load. Such parts must be made more robust in terms of size and weight in order to be able to withstand these large forces. An example of these large forces is the tension force in the cord or chain (d) connecting the eyes of the pincer-shaped rods, caused by a pulling force exerted by the patient on the handle or handle (e). Each side of the cord or chain must bear its part of the vertical component of the force, ie half the weight of the load, but also, due to the angle that the cord describes with respect to the vertical, a significant horizontal component. The total force on each side of the cord or chain is therefore much higher than half the weight of the load on the handle. This tensioning force in the cord or chain is fully and laterally transferred to the tongs (a and b) of the clamping device, which must therefore be made of a sturdy and heavy material and have suitable dimensions to be able to to withstand forces. Another example of the large forces on the clamping device are the forces that act on the hinge (c) connecting the tongs. The strong force transmitted by the cord or chain (d) to the bars (a and b) at their point of attachment to the bars, ie at a considerable distance from the upper bar (g), has due to the leverage effect and the much shorter distance from the hinge (c) to the upper bar (g) as a result of which an even higher force is exerted on the hinge (c). The forces that pull on the pincer-shaped bars are thus concentrated and considerably strengthened in the hinge, such that the hinge forms a weak part of the clamping device if it is not strong enough.
Yet another drawback of such a clamping device is that the handle or the handle cannot be positioned or brought close to the upper bar, which limits the range of movement of the handle or the handle with respect to the upper bar. First, the tong-shaped bars must have a certain length, such that a lever is formed which makes it possible to clamp the clamping device onto the upper bar. As a result, the handle or the handle is already placed at a certain minimum distance below the upper bar. Secondly, the cord or chain connecting the eyes of the pincer rods should bend down, if only to keep the force in the cord or chain within acceptable limits. This imposes an additional distance between the handle or handle and the upper bar.
The present invention has for its object to remedy or at least mitigate the problems described above, and / or to provide improvements in general.
SUMMARY OF THE INVENTION
According to the invention, an assembly is provided of a clamp, a belt and a rod, the assembly being arranged such that the position of the clamp and / or the belt is fixed relative to the rod when a load is suspended from the rod and / or the clamp by means of the belt, a device for lifting a patient comprising the assembly, a device for assisting in positioning or repositioning a patient in a bed comprising the assembly, and a method for manufacturing the assembly and the other objects provided.
To this end, the invention provides in one embodiment an assembly of a clamp, a belt and a rod, wherein the belt has a longitudinal direction, wherein the belt is suitable for possibly directly attaching a load to be suspended from the rod and / or the clamp via at least one end of the belt, wherein the clamp and / or the belt comprises an contractible gripping portion which is provided to grip around the rod to enable clamping of the clamp and / or of the belt on the rod, the belt engaging the clamp along a first contact line and along a second contact line, each contact line extending transversely of the longitudinal direction of the belt, the two parts of the belt adjacent the first contact line forming an angle about the first contact line, such that when a load is suspended at the at least one end of the belt, the belt exerts a force on the clamp at the first contact line, said force being at the clamp j pushes the first contact line in a direction relative to the second contact line, this direction representing a closing direction of the clamp and / or the belt, whereby the gripping portion is pressed against the rod.
We have found that when the clamp of the assembly according to the present invention is moved in the closing direction by the force exerted on the clamp at the first contact line, for example under the influence of the load, the position of the gripping portion, and thereby also the person of the clamp and the belt provided with the gripping part is then fixed relative to the rod. This entails the advantage that it is prevented that the person of the clamp or the belt provided with the gripping portion can slide longitudinally, i.e. along the longitudinal axis of the rod. It also entails the advantage that it is prevented that the person of the clamp or belt provided with the gripping portion can slide transversely, i.e. along a direction perpendicular to the longitudinal axis of the rod. Because the belt is in engagement with the clamp, securing the clamp or the belt provided with the gripping portion relative to the rod can also lead to securing the position of the person of the clamp or the belt not provided with of the gripping portion, thereby preventing the person from the clamp or belt not provided with the gripping portion from sliding longitudinally and / or transversely of the rod.
When no load is suspended from the belt, and therefore the gripping portion does not press against the rod, the clamp and the belt can remain movable relative to the rod.
We have found that the fact that the belt forms an angle around the first contact line leads to a reduction in the forces exerted on the clamp at the first contact line, which are the result of the tension forces in the belt when a load is suspended at least one end of the belt. These reduced forces are still sufficient to contract the gripping portion around the rod such that the clamp and / or the strap clamps around the rod, thereby fixing the position of the clamp relative to the rod. The reduced forces, however, entail the advantage that the forces on the clamp itself are reduced and allow smaller and / or lightweight embodiments of the clamp and / or the use of lightweight materials.
Another advantage of the assembly according to the present invention is that the load suspended at the at least one end of the belt can be moved very close to the clamp, ie very close to the first contact line between the clamp and the belt . Because the clamp can also be made smaller and / or lighter, since the clamp, as explained above, is subject to smaller forces, the load can moreover be moved or positioned even closer to the rod. The assembly according to the invention thus allows a wider range of movement of the load suspended from the belt relative to the clamp, and also relative to the rod.
The fact that the load suspended from the belt can be placed closer to the clamp entails the additional advantage that the leverage forces that the load causes on the structure supporting the rod can have a smaller lever arm. This allows the use of lightweight embodiments and the use of lightweight materials for many components of the supporting structure.
In another embodiment, the invention provides a device for lifting a patient that includes two arms for gripping a patient on either side of the patient's chest, and that are formed accordingly, and wherein leg supports are suspended from the arms by by means of belts, using the assembly according to the present invention.
The lifting device brings with it the advantage that when the patient is with the legs in the leg supports, the gripping part is pressed against the arm, whereby the position of the clamp and the belt relative to the arms is fixed. In this way, the belt and the clamp are prevented from sliding on the arm of the lifting device while the patient is being carried in the lifting device, which could lead to the position of the patient in the lifting device changing adversely, which is disturbing or could even be harmful to the patient. When the patient's leg is moved out of the leg support or lifted up relative to the leg support, and thus no load or at least no significant load is suspended from the belt anymore, the clamp and the belt can be restored be adjusted to move on the arm, such that the position of the clamp and / or the belt with which the leg support is suspended from the arm can be adjusted to the needs of the patient.
In addition, the arms of the lifting device may be provided with cup-shaped structures that are to be positioned under the patient's armpits on either side of the patient's chest. The cup-shaped structures may be formed on their upper surface to engage under the patient's armpits, and may be provided with a curvature corresponding to the curvature of the patient's chest, and may be fixedly mounted on the arms of the patient. lifting device or may be tiltably mounted on the arms of the lifting device such that their position can be changed in accordance with the patient's chest.
In another embodiment, the invention provides an apparatus for assisting in positioning or repositioning a patient in a bed, comprising a handle and a strap attached to the handle and suspended from an upper bar above the bed by means of the assembly according to the present invention.
The device for assisting in positioning or repositioning the patient in the bed brings with it the advantage that when the patient pulls the handle, the gripping portion is pressed against the upper bar, thereby increasing the position of the clamp and the belt. relative to the upper bar. In this way, the strap and the clamp are prevented from sliding along the upper bar while the patient adjusts his / her position in the bed by pulling on the handle. This ensures that the position of the handle does not suddenly change, which could cause the patient to get hurt. When the patient ceases to pull on the handle and there is therefore no more a load, or at least no significant load anymore, on the belt, the clamp and the belt can be re-enabled to move on the upper bar such that the position where the handle is suspended from the upper bar can be adjusted to the needs of the patient.
The use of the device to assist in positioning or repositioning a person in a bed is not limited to the bed alone. The device can also be mounted on a chair, on a club chair, on a sofa, on a couch, on a toilet, in a shower, or on other specialized material for the care of a patient which may require an adjustable handle.
In another embodiment, the invention provides a method for manufacturing the assembly of the present invention, the method comprising the steps of: providing a material for forming the clamp, and forming the clamp of the assembly by to bring the material for forming the clip to a predetermined shape, comprising the part of the clip that includes the first contact line and the part of the clip that includes the second contact line.
This method is very easy to implement, with a minimum of training for technical staff. A production of the clamp in a single step can be made possible. The production also requires only one element of base material, i.e. the metal wire. This brings additional logistical benefits.

In the context of the present invention, an angle of X °, where X is a number, is an angle of (2πΧ) / 360 radians. 2π radians correspond to a full circle.
In the assembly according to the present invention, the clamp comprises the gripping portion.
This embodiment entails the advantage that the belt can be made of a suitable flexible material, while the clamp can be made of a suitable solid material.
In an embodiment of the assembly according to the present invention wherein the clamp comprises the gripping portion, the clamp comprises an additional gripping portion to grip around the rod to allow for clamping on the rod.
The inventors have found that the additional gripping portion, in addition to the gripping portion, is advantageous for increasing the engagement surface of the clamp on the rod, and thereby the grip of the clamp on the rod, when a load is suspended from the at least one end of the belt, whereby the position of the clamp and the belt relative to the rod is fixed more firmly. An additional advantage is that the clamp can clamp on the rod at several places at the same time, so that the clamp can be better immobilized with respect to the rod.
In an embodiment of the assembly according to the present invention wherein the clamp comprises the additional gripping portion, the additional gripping portion is connected to the gripping portion via the clamping portion that includes the first contact line and / or the clamping portion that includes the second contact line.
The fact that the additional gripping part is connected to the gripping part via the clamping part which comprises the first contact line and / or the clamping part which comprises the second contact line entails the advantage that no additional clamping parts with additional contact lines have to be provided between the clamp and the belt for operating the additional gripping portion of the clamp, which simplifies the design of the clamp.
In an embodiment of the assembly according to the present invention in which the clamp comprises the additional gripping portion, the additional gripping portion is connected at both ends to the gripping portion, the two connections being either via the clamping portion with the first contact line or via the clamping portion with the second contact line expired.
The two gripping portions of the clamp or belt are thus in each case separated from each other by a clamping portion comprising one of the contact lines, and conversely the two clamping portions comprising the contact lines are separated from each other by the two gripping portions. These separations make it possible to maintain a distance between the two gripping portions, and also a distance between the two contact lines, which on the one hand offers better ways to immobilize the clamp relative to the rod, and on the other hand more flexibility in the locking mechanism of the clamp.
In an embodiment of the assembly according to the present invention wherein the clamp comprises the additional gripping portion, the additional gripping portion grips around the rod at a distance from the location where the gripping portion grips around the rod.
This entails the advantage that rotation of the clamp can be prevented when the clamp is closing or closed under the force of the suspended load, around an axis that runs perpendicular to the longitudinal axis of the rod.
In an embodiment of the assembly according to the present invention wherein the clamp comprises the additional gripping portion at a distance from the gripping portion, the strap passes through the clamp between the gripping portion and the additional gripping portion.
This entails the additional advantage that the belt engaging the clamp at the first contact line and the second contact line is enclosed by the gripping portion and the additional gripping portion from opposite sides and is limited in its movement relative to the rod, which contributes to preventing the belt from sliding over the rod along the longitudinal axis of the rod, and furthermore may help prevent the belt from sliding off the clamping parts with the contact lines and coming out of engagement with the clamp. As such, the gripping portion and the additional gripping portion form a retaining means for the belt.
In the assembly according to the present invention, at least one of the gripping portion and, if present, the additional gripping portion is resilient, preferably both, if present, being resilient.
The fact that the gripping portion and / or the additional gripping portion is resilient offers advantages for the operation of the gripping portion and / or the additional gripping portion. On the one hand, the resilience is a simple way of arranging the gripping portion and / or the additional gripping portion such that when the first contact line is pushed in the closing direction towards the second contact line, the gripping portion presses against the rod. On the other hand, the resilience also provides a simple way to return the gripping portion and / or the additional gripping portion to their original position when the load is removed from the belt, without additional interaction being required with the gripping portion and / or the additional gripping portion. In this way it can be ensured that the gripping part and / or the additional gripping part no longer press against the rod, and the clamp and the belt can again be made freely movable on the rod, if necessary, under the influence of only a small force.
In the assembly according to the present invention, the at least one of the gripping portion and, if present, the additional gripping portion is resiliently provided with a bias to press against the rod, even when no load is suspended from the at least one end of the belt.
The resilient gripping part and / or the resilient additional gripping part are provided with a bias such that the gripping part and / or the additional gripping part already press against the rod, preferably with a predetermined amount, when no load is suspended on the belt, entails the advantage that the position of the gripping portion and / or the additional gripping portion is already somewhat fixed relative to the rod before a load is suspended from the belt. In this way, the clamp and the belt cannot move accidentally or unintentionally relative to the rod when the assembly according to an embodiment of the present invention is not in use. In this way, the clamp and the belt can easily be held in a preferred position with respect to the rod. By subsequently suspending a load on the at least one end of the belt, the gripping part and / or the additional gripping part is further pressed against the rod, such that the position of the clamp and the belt relative to the rod is more firmly fixed at relative to the rod.
In an embodiment of the assembly according to the present invention, the first contact line and the second contact line are substantially parallel, and preferably parallel, to each other.
The fact that the first contact line and the second contact line run substantially parallel to each other entails the advantage that forces on the first contact line and on the second contact line will not lead to a rotation component in the movement of the clamp on the rod, which can lead to an undesired rotation of the clamp, and which can also lead to undesired lateral forces on certain parts of the clamp.
In an embodiment of the assembly according to the present invention, the clamp comprises retaining means to prevent the belt from sliding over the rod relative to the clamp in a direction parallel to a longitudinal axis of the rod when the belt exerts a force on the clamp along the first contact line and along the second contact line.
The retaining means have the advantage that they prevent the belt from sliding off the parts of the clamp with the contact lines, and thereby fall out of engagement with the clamp.
This is advantageous for the safe use of the assembly according to an embodiment of the present invention. If the belt were to slide off the parts of the clamp with the contact lines, the load suspended from the rod via the belt and / or the clamp would suddenly move to another position on the rod, or it could even fall if it is only suspended from the clamp. This could cause damage to the suspended load, such as, for example, a person using the device for lifting the patient according to the present invention or the device for assisting in positioning or repositioning a patient in a bed according to the present invention. . If the belt slides off the parts of the clamp with the contact lines, that would also adversely affect the reliability of the assembly according to the present invention.
In an embodiment of the assembly according to the present invention, the clamp is arranged such that, when no load is suspended from the belt, the clamp at the first contact line can be pushed manually in a direction relative to the second contact line and against the closing direction of into the clamp and / or belt, this direction representing an opening direction of the clamp and / or belt, as a result of which a gripping pressure of the gripping part is released against the rod.
The clamp, which is arranged to be opened manually, has the advantage that it is easy to reposition it with respect to the rod. To this end, the clamp only needs to be opened by pushing the clamp at the part with the first contact line in the opening direction with respect to the second contact line, whereafter the clamp and belt can be moved easily over the rod. The ability to open the clamp removes any friction between the gripping portion and the rod, such that the clamp and the belt can be moved easily and without much resistance over the rod.
In an embodiment of the assembly according to the present invention, the belt is suitable for directly attaching a load to be suspended from the rod via at least one end of the belt.
Suspending the load on the rod via at least one end of the belt has the advantage that the weight of the load is carried by the rod and that the clamp only undergoes the force at the first contact line when a load is suspended on the belt, which does not necessarily have to be as large as the weight of the load, but only needs to push the clamp at the first contact line in the closing direction with respect to the second contact line and press the gripping portion against the rod possible. In this way the forces that the clamp must be able to withstand are smaller, such that smaller, lightweight embodiments of the clamp are possible, and / or the use of lightweight materials is possible.
In an embodiment of the assembly according to the present invention, the clamp is configured such that the force exerted on the clamp at the first contact line when a load is suspended at the at least one end of the belt, the clamp at the first contact line. pushes a direction away from the second contact line.
This embodiment entails the advantage that the belt can be arranged between the parts of the clamp with which the clamp comes into engagement with the belt at the first contact line and the second contact line. This is advantageous for maintaining the position of the belt relative to the clamp to ensure proper operation of the assembly according to an embodiment of the present invention.
If, moreover, the clip is arranged to be opened manually by pushing the clip at the first contact line in the opening direction relative to the second contact line, then this embodiment also has the advantage that opening the clip is easy with one can be carried out manually by pushing the clamp at the part with the first contact line in a direction towards the part with the second contact line. This is much easier to do than, for example, pushing the clamp with one hand at the part with the first contact line in a direction away from the second contact line. In this way, the second hand of a person using the assembly according to an embodiment of the present invention remains free to perform other tasks during opening of the clip, such as holding onto a support for the patient holding the clip and the wish to reposition the belt in relation to the rod.
In an embodiment of the assembly according to the present invention, the two parts of the belt adjacent the second contact line form an angle around the second contact line such that when a load is suspended at at least one end of the belt, the belt forms a exerts additional force on the clamp at the second contact line, the additional force pushing the clamp at the second contact line in a direction relative to the first contact line, this direction representing the closing direction of the clamp and / or the belt, whereby the gripping portion is pressed against the rod.
With this embodiment, not only does the part of the belt that engages the clamp at the first contact line exert a force on the clamp to press the gripping portion against the rod, but also exerts the part of the belt that engages with the clamp a force on the clamp at the second contact line, ie the additional force, pressing the gripping part against the rod. This entails the advantage that the gripping portion is pressed more forcefully against the rod, which leads to a more firm fixation of the position of the gripping portion, and consequently also of the clamp and the belt, against the rod. The forces exerted on the clamp at the first contact line and at the second contact line also have the advantage that forces for pressing the gripping portion against the rod are more evenly distributed over the clamp, resulting in a better controlled pressing of the gripping part against the rod.
In an embodiment of the assembly according to the present invention, the angle around the first contact line is formed by the two parts of the belt adjacent the first contact line, and / or, if present, the angle around the second contact line that is formed by the two parts of the strap adjacent to the second contact line, in the range of 90 ° to 170 °.
Increasing the magnitude of the angle around the first contact line formed by the two parts of the belt adjacent the first contact line decreases the force exerted by the belt on the clamp at the first contact line when a load is present suspended from the at least one end of the belt, and decreasing the magnitude of this angle increases this force.

Figure 1 is a perspective view of an assembly of a clamp 1, a belt 2 and a rod 3 according to the present invention. Figures 2 and 3 show a more detailed view of a part of the same assembly shown in Figure 1, in a perspective view and a side view, respectively. Figures 4-6 show the clamp 1 of the assembly in more detail from different sides, respectively in a front view, a side view and a bottom view.
The assembly will now be further discussed with reference to these figures and with reference to Figures 8 and 7, in which the closing of the clamp 1 is demonstrated, respectively in a perspective view and in a detailed side view, and with reference to Figures 9. and 10, in which the opening of the clamp 1 is demonstrated, respectively in a perspective view and in a detailed side view.
In this embodiment, the rod 3 is provided as a tube 3 with a circular cross-section that extends in a longitudinal direction. However, in other embodiments, the rod 3 may also be a solid rod instead of a hollow tube, and may also have other cross-sectional shapes.
The belt 2 is a narrow, usually flat strip of a flexible material. The belt 2 extends in a longitudinal direction and is suitable for possibly directly attaching a load to be suspended from the rod 3 and / or the clamp 1 via at least one end of the belt 2.
The clamp 1 is formed by a bent metal wire, preferably a bent wire of stainless spring steel, the ends of which are welded together.
The clamp 1 is arranged on the rod 3 and the belt 2 forms a loop that runs over the rod 3 and through the clamp 1. The belt 2 is adapted to be connected to a load which is to be suspended from the rod 3 and / or the clamp 1. In this embodiment the belt 2 runs over the rod 3 in such a way that the longitudinal direction of the belt 2 the longitudinal direction of the rod 3 intersects, and is preferably perpendicular to this. In this way a load suspended on the belt 2 is suspended on the rod 3, such that the rod 3 essentially carries the weight of the suspended load.
In alternative embodiments, the belt does not run over the rod, but can also only run through the clamp, as can be seen, for example, in Figures 12e-g. In this way, a load suspended on the belt 2 is suspended on the clamp 1, such that the clamp 1 essentially carries the weight of the suspended load.
The belt 2 comes into engagement with the clamp 1 at a first contact line 11 and at a second contact line 12. As can be seen, for example, in Figure 3, the parts of the belt 2 that border the first contact line 11 and the parts of the belt 2 which are adjacent to the second contact line 12 at an angle around the first contact line 11 and the second contact line 12. When a load is suspended from the belt 2, the tension forces in the belt 2 generate a force on the clamp 1 at the first contact line 11. and at the second contact line 12 because of the angle that the belt forms around the first contact line 11 and around the second contact line 12. The angle between the two parts of the belt 2 adjacent the first contact line 11 and the angle between the two parts of the belt 2 adjacent the second contact line 12 are preferably in the range of 90 ° to 170 °. The force exerted on the terminal 1 at the first contact line 11 and the force exerted on the terminal 1 at the second contact line 12 are preferably in the range of 10 N to 2000 N.
The clamp 1 comprises a gripping portion 13 and an additional gripping portion 14 which are adapted to grip around the rod 3. The gripping portion 13 and the additional gripping portion 14 have an a-shape which provides an opening through which the rod 3 is passed to mount the clamp 1 on the rod 3. To enable the rod 3, on the one hand, to pass through each of these openings and, on the other hand, to allow the gripping portion 13 and the additional gripping portion 14 to engage the rod 3, the circular cross-section of the gripping portion 13 and the additional gripping portion 14 is provided with a radius of curvature only slightly larger than the outer radius of the rod 3.
The gripping portion 13 and the additional gripping portion 14 are arranged at a predetermined distance from each other such that the belt 2 is able to be passed between the gripping portion 13 and the additional gripping portion 14. The predetermined distance between the gripping portion 13 and the additional gripping portion 14 is preferably only slightly larger than the width of the strap 2 to limit the movement of the strap 2 between the gripping portion 13 and the additional gripping portion 14. The gripping portion 13 and the additional gripping portion 14 are connected to each other via a part of the clamp 1 that provides the first contact line 11 for coming into contact and engaging the belt 2 and via a part of the clamp 1 that the second contact line 12 provided for contacting and engaging the belt 2. These clamping members run substantially parallel, and preferably parallel, with each other and with the longitudinal direction of the rod 3. In this configuration, the gripping portion 13 forms the additional gripping portion 14 , the clamping part providing the first contact line 11 and the clamping part providing the second contact line 12 a retaining means for the belt 2, which drags the belt 2 together with the clamp 1 when the clamp 1 is moved along the rod 3, and which prevents the belt 2 slides off the clamp 1 when, for example, the belt 2 exerts a force on the clamp 1.
In this embodiment, the gripping portion 13 and the additional gripping portion 14 are resilient, and generally at least contractible. This makes it possible that, as can be seen in Figures 7 and 8, a force on the terminal 1 at the first contact line 11 displaces the terminal 1 at the first contact line 11 in a direction away from the second contact line 12, and that a force on the terminal 1 at the second contact line 12, the terminal 1 at the second contact line 12 moves in a direction away from the first contact line 11, ie a closing direction of the terminal 1. The force exerted on the terminal 1 in the closing direction can, for example, be the force applied to the clamp 1 at the first contact line 11 and at the second contact line 12 when a load is suspended at the at least one end of the belt. Moving the clamp 1 at the first contact line 11 and at the second contact line 12 in the closing direction reduces the radius of curvature of the circular cross-section of the gripping portion 13 and the additional gripping portion 14, whereby the gripping portion 13 and the additional gripping portion 14 abut against the rod 3 be pressed such that the position of the clamp 1 relative to the rod 3 is fixed.
The gripping portion 13 and the additional gripping portion 14 can be arranged in such a way that, when no forces are exerted on the clamp 1, the clamp 1 is freely movable along the rod 3. The clamp 1 can thus slide in the longitudinal direction, ie along the longitudinal axis of the rod 3, and slide transversely, ie along a direction transverse to the longitudinal axis of the rod 3.
However, the gripping portion 13 and / or the additional gripping portion 14 can also be provided with a bias, such that when no forces are exerted on the clamp 1, the gripping portion 13 and / or the additional gripping portion 14 already press against the rod, preferably with a predetermined amount, whereby the position of the clamp 1 is already somewhat fixed relative to the rod 3.
When the position of the clamp 1 relative to the rod 3 is fixed, the clamp 1 can be opened, as can be seen in Figures 9 and 10, by exerting a force on the clamp 1 at the first contact line 11 which terminal 1 at the first contact line 11 moves in a direction towards the second contact line 12, and by exerting a force on the terminal 1 at the second contact line 12 which moves the terminal 1 at the second contact line 12 in a direction towards the first contact line 12 contact line 11, i.e. the opening direction of the clamp 1. Such a force can be exerted manually, as can be seen in Figure 9, but can also result from the resilience of the gripping part and the additional gripping part. In the case that, for example, the gripping portion 13 and / or the additional gripping portion 14 are provided with a bias and no forces are exerted on the clamp 1, a manual force can be exerted on the clamp 1 in the opening direction to overcome the bias , and in the event that a previously exerted force on the clamp 1 is released in the closing direction, the resilience of the gripping portion 13 and the additional gripping portion 14 may provide the force for opening the clamp 1. Moving the clamp 1 at the first contact line 11 and at the second contact line 12 in the opening direction increases the radius of curvature of the circular cross section of the gripping portion 13 and the additional gripping portion 14, thereby ensuring that the gripping portion 13 and the additional gripping portion 14 no longer press against the rod 3 , such that the clamp 1 is freely movable relative to the rod 3.
In alternative embodiments, the clamp may be arranged such that a force on the clamp 1 in the closing direction moves the clamp 1 at the first contact line 11 in a direction toward the second contact line 12, and at the second contact line 12 in a direction toward the first contact line 11, and such that a force on the clamp 1 in the opening direction moves the clamp 1 at the first contact line 11 in a direction away from the second contact line 12 and at the second contact line 12 in a direction away from the first contact line 11. Examples of such embodiments are shown in Figures 12b-g.
In alternative embodiments, the belt 2, instead of the clamp 1, may be provided with the gripping portion 13 and optionally the additional gripping portion 14. An example of such an embodiment can be seen in Figure 12h.
In this embodiment, the assembly is furthermore provided with an adjustment element 21, more in particular a buckle 21, which is arranged on the belt 2. The adjustment element 21 is adapted to adjust the length of the belt 2 such that the distance between an suspended load and the rod 3 and clamp 1 can be adapted, for example to a specific application or to the specific needs of a person using the assembly.
In this embodiment, the assembly is furthermore provided with a support element 41 which is connected to the belt 2, more particularly a leg support 41. The support element 41 is adapted to carry a load suspended from the belt 2, or at least facilitate the suspension of a load on the belt 2.
As can be seen in Figure 11, the belt 2 is provided with a connecting element 22 and the supporting element 41 is provided with a connecting slot 43 for connecting the belt 2 and the supporting element 41. The connecting element 22 and the connecting slot 43 are dimensioned such that the connecting element 22 is able to be passed through the connecting slot 43 in a first orientation, as can be seen in the left-hand part of Figure 11. In this way the connecting element 22 and the belt 2 can be introduced through the connecting slot 43 for connecting the belt 2 and the supporting element 41, and in the other direction the connecting element 22 and the belt 2 can also be withdrawn through the connecting slot 43 for uncoupling the belt 2 and the supporting element 41. The connecting element 22 and the connecting slot 43 are also dimensioned such that when the connecting element 22 is inserted through the connecting slot 43 eight, the connecting element 22 nestles behind the sides of the connecting slot 43. In this way, the supporting element 22 is supported on the connecting element 22 for connecting the belt 2 and the supporting element 41. In this embodiment, the supporting element 41 is even provided with a connecting recess 44 around the connecting slot 43, and having a shape that is substantially complementary to the shape of the connecting element 22, the connecting element 22 being in this connecting recess 44.
