description
The invention relates to a tensioning ratchet with tension indicator with the features of the preamble of claim 1 and a tension indicator according to the features of the preamble of claim 6.
State of the art
Spannratschen, or belt retractor called, find particular in the field of truck freight transport application and are known in various embodiments. A tension belt usually consists of a lashing strap and a tensioning ratchet connected to the lashing strap. The lashing strap consists of a webbing made of textile or chemical fiber. The European standard «DIN EN12 195-2 Lashing straps made of manmade fibers» has been in force since February 2001. All lashing straps manufactured since this date comply with these specifications or standards.
The tensioning ratchet is a tensioning element that is predominantly used when using lashing straps. The tensioning ratchet consists of a frame part in which a take-up shaft is rotatably mounted. Further, a clamping lever is provided which moves the take-up reel in a direction of rotation via a slidably mounted within the clamping lever locking slide. The locking slide itself engages in a ratchet, which is rotatably coupled to the take-up shaft. By reciprocating the clamping lever, the winding of the lashing on the winding shaft is effected. If a loosening, the locking slide is disengaged and due to the bias of the lashing wraps at least partially automatically from the take-up shaft.
The tension ratchets must be designed so that a deliberate action is necessary to solve them. In order to avoid injuries, all types of clamping elements must work without recoil. This requirement is met when the tensioning lever of the tensioning ratchet under tension does not return more than 15 cm when opened. The ratchet performance, ie the amount of achievable preload force depends very crucially on the design of the tensioning ratchet used.
For the handling of lashing the lashing strap is threaded into the take-up shaft on the tensioning ratchet and wound with the actuation of the clamping lever on the take-up shaft of the tensioning ratchet. To ensure a tight fit of the webbing, approx. Two turns of the lashing strap must be applied to the take-up reel. It must be ensured that no more than 3 to 4 turns rest on the take-up shaft, otherwise there is a risk that the tensioning ratchet may open uncontrollably.
There are different types of ratchets. These differ on the one hand by the length of the ratchet lever. Here, short lever ratchets or so-called "standard ratchets" are known, which have a lever length of about 20 to 25 cm. With these standard tension ratchets preload forces from 200 daN to 400 daN can be achieved.
A development are so-called "train or Langhebelratschen". These differ from the short lever ratchet particular in that the lever arm is much longer. This is about 30 to 35 cm. The advantage here is that due to the corresponding lever attack or the torque to be applied, biasing forces in the range between 400 daN and 600 daN can be applied. A higher preload force means that significantly less lashing (tension ratchet with tension belt) is required to secure the load, especially during tie-down operations. The biasing force thus gives a quality for the lashing of the corresponding object.
According to the specifications of DIN EN 121 95-2, the performance of the tensioning ratchet is also noted on the lashing strap label with the abbreviation STF. Some tension ratchets are marked with numbers like 2500 daN or 4000 daN. This is an indication of the lashing force (but not on the preload force) of this tensioning ratchet.
To apply the necessary tensile force or to achieve the biasing force is provided to apply a normal hand force in the amount of 50 daN. Although it is conceivable that higher forces can be applied by, for example, extensions are arranged on the Spannratschenhebel. However, these usually result in overuse of the tensioning ratchet and potentially serious injury to the user if the limits are exceeded accordingly.
Lashing down, a force-locking method, is the most commonly used in road haulage cargo securing method. A secured frictional connection is ensured if the preload force Fv together with the frictional force Fwso is sufficiently dimensioned to compensate for forces acting on the load. Lashing down is usually done by the lashing straps mentioned, which are stretched over the load. With the pretensioning force, the lashing straps act vertically on the load and on the loading area.
The preload forces add up to the present weight of the load and create sufficient contact pressure, so that acting forces can not move the charge.
The diagonal lashing or diagonal lashing differs in principle from lashing down, because here the permissible tensile force as restraint force is crucial and not the preload force. The lashing straps must therefore be designed so that the load is evenly secured in the direction of the forces occurring. The lashing points on the load carrier or on the load must absorb the introduced force.
It is recommended to use a maximum of 50% of the permissible tensile force as a preload force. The DIN EN 121 95-2 for lashing straps requires the specification of the STF (Standard Tension Force) for preload force on the label of a lashing strap.
But since there are different clamping elements, it is crucial for the operator to know which biasing force he applies with his lashing straps.
Decisive for lashing the charge, however, is the biasing force. Here are known from the prior art preload force measuring devices that determine by depressing the lashing strap, as this can be correspondingly bend at one point. If you have no preload force meter, you can help yourself with a finger test. The lashing strap must sound like a guitar string.
From DE 3 240 993 a tensioning ratchet with a tension indicator is known, which indicates the tension applied to a lashing belt, caused by the tensioning of the tensioning ratchet. In this case, a part of the tensioning ratchet is decoupled from the remaining part and pressed against a spring element when the corresponding tension is applied to the lashing. The clamping force display is realized by a bar marking in connection with a clamping force limitation with simultaneous locking of the ratchet wheels of the tensioning ratchet.
From DE 8 229 264 a tensioning device for lashing straps is known, by means of a proper tension of lashing straps can be determined. For this purpose, two mutually movably provided fasteners are provided, each having at their ends receptacles that are suitable for attaching lashing straps. Between the cross-fastened fastening parts a spring element is arranged. The spring elements are constantly loaded on pressure and are also exposed to maximum forces.
Disadvantages of the prior art
The basic function of lashing straps is that loads are safely and reliably secured during transport. There is a risk that, due to shaking movements, braking movements and accelerations, the lashing belts loosen and the load is no longer firmly lashed. This occurs in particular when the necessary preload force is not applied to the lashing during load securing.
Although it is known from the prior art devices, in particular electrically operated devices, which detect and measure the biasing force.
However, for everyday use, these are not practical, since they are usually exposed to very high loads, and then due to the fact that it is a very sensitive meter, no longer work properly. In addition, they are battery-powered, so that a permanent use is not easily guaranteed.
The known from the prior art tensioning ratchet with an integrated clamping force indicator is designed as a very complex component. Several relative movements to each other that are under extreme tension can withstand only a very limited extent under the extreme conditions to which tensioning ratchets of the above type are exposed, in particular on trucks. The many moving parts mean that a non-standard tensioning ratchet has to be used, which in turn leads to extremely high costs for approval and testing.
This also applies to the tensioning device for lashing straps as a display element. The two mutually movable fasteners are exposed to extreme tensile loads, the two parts are coupled together exclusively by spring elements. An overload of the springs is very likely because the tension adjustment are very large in tension ratchets, which are used in particular on trucks. Overloading is therefore likely. The springs are thus extremely deformed, so that they can not take over the necessary display function.
For the use of such Spannratschen and clamping force indicators, it is necessary that they can withstand the extreme conditions, such as improper treatment, extreme weight shifts, but also spray rain and salt water and snow and ice.
Object of the invention
The object of the invention is to provide a simple device, with which it is ensured that the necessary biasing force is applied to the load.
Solution of the task
The solution of the problem is to provide a tensioning ratchet with a tension indicator, which constantly measures the biasing force in the belt. The solution of the problem consists in the features of the characterizing part of claim 1.
Advantages of the invention
One of the main advantages of the invention is that during the clamping process, the user can already recognize whether he has reached the necessary biasing force or not.
Even during a long period of time (especially during transport) can be determined constantly by an optical control, whether the necessary clamping force is still present or not. Thus, a sporadic, but reliable control is possible.
The tension indicator is designed such that it is preferably designed exclusively mechanically. This has the advantage that neither batteries nor other electrical elements are necessary. This in turn means that a permanent and proper use is possible. A permanent use, regardless of weather, dirt and other environmental influences is guaranteed without maintenance.
The tension indicator itself is designed spring loaded. This means that a movable element is pressed against a fixed element by the tensioned lashing strap, wherein the pressing against the spring forces - which are provided by spring elements - takes place. Spiral springs are preferably not used as spring elements, but so-called polyurethane springs are used. These are cylindrical in shape and have in the middle a cavity in the formation of a centrally disposed through bore (in the longitudinal axis). The cavity is adapted to penetrate this example with a screw, so that the spring can be positioned.
The inventive tension indicator is as previously stated, spring loaded. It is quite conceivable to interpret this with at least one spring element, or even two springs arranged in parallel. The springs are arranged within the moving element and the fixed element and have the property to be loaded under appropriate tensile load on pressure. The design of the spring elements is such that they can be claimed with a corresponding safety factor of at least 4 kN. However, if too high a load, ie a tensile load applied far over the 4kN, so a corresponding overload protection is provided. This is designed such that when the corresponding train or pressure load limit is exceeded, the movable element moves against the fixed element in abutment. This is achieved in that support elements are present within the spring elements, which are aligned in the direction of the fixed or movable element. In the unloaded state, there is a gap between these support elements. With increasing load, the corresponding support elements move towards each other. Up to a corresponding limit load, here for example 4kN, a corresponding distance is still maintained. If this limit load is exceeded, the respective end faces of the support elements touch and a frictional connection between the movable element and the stationary element is achieved. This means that the springs claimed thereby are not further compressed. A plastic deformation and thus a distortion of the spring hardness is thus completely excluded.
The support elements additionally have the advantage, since they are arranged within the spring elements, these also lead. This means that the pressure-loaded springs have no possibility to escape from the space formed by the movable element and fixed element.
In addition, this is further supported by the lashing strap "loops around" the movable element and so completely covers the space occupied by the spring elements on both sides. As a result, at least the penetration of moisture, dirt, ice, salt or similar interfering media is at least partially prevented.
A permanent function of the spring elements is guaranteed.
The tension indicator can have different maximum clamping values depending on the design of the tensioning ratchet. This is achieved by using different spring constants for the spring elements.
The movable element is mounted in a guide in the frame part of the tension indicator. Characterized in that the frame part is formed like a sheet, the storage takes place in a longitudinal slot. On the frame part a position mark is provided, which indicates which minimum preload value has to be reached, so that the charge is securely fixed. If the tensioning belt is lashed and fixed with the tensioning ratchet according to the invention, it is achieved by reciprocating the tensioning lever that the movable element of the tensioning force indicator moves within the longitudinal slot, namely in the direction of the stationary element.
If the position mark is reached by the movable element, this is a signal for the viewer that the specified preload force in the lashing now applied. Thus, in this simple and visual manner, the viewer and user of the tensioning ratchet can be sure that the necessary and thus prescribed biasing force has been applied.
Also for checks, for example, for truck controls, which are carried out by the police, such a strap is. Because by a simple visual inspection can be found in a simple manner that the necessary clamping force has been achieved.
Another significant advantage of the invention is that the clamping force indicator can be attached as an additional component to any known tensioning ratchet, even subsequently in the form of a retrofit. The tension indicator is designed such that it has an interface element which is suitable for adaptive arrangement on a conventional tensioning ratchet.
The tension indicator can also be used as a stand-alone component. He is particularly suitable to represent the clamping force in a lashing, averted from a tensioning ratchet. For this purpose, a housing-like configuration is preferably also provided, within which a fixed element and a movable element, however, are arranged. The movable element is also loaded with respect to the stationary element also and is looped around by a Lashing strap. An interface element provides either to be connected to an existing ratchet or to receive a lashing strap, which can be guided to a tensioning ratchet.
In particular for securing cargo is provided to arrange the tensioning ratchet on one side of the cargo, whereas the longer part of the lashing belt is guided over the load and can be fixed on the opposite side. As a result, due to the applied bias, the charge to be secured is forced onto the corresponding surface. Possible friction mats under the load additionally serve to secure the load. If a tensioning ratchet according to the invention is used with an integrated tension indicator, it may be possible that the identical tension is not applied to the opposite side. In order to be certain, it is advantageously proposed to additionally integrate a further tension indicator in the lashing strap. As a result, the user has the ability to determine on both sides of the load, that is in the immediate vicinity of the anchor points, if the necessary bias is present on the lashing straps.
A development of the previously described tensioning ratchet provides that the tension indicator is an integral part of the tensioning ratchet. This is achieved by the fact that the frame parts comprising the tensioning ratchet continue to extend correspondingly and additionally include the correspondingly fixed element or the element of the tensioning force indicator which is movable relative to this. Thus, the tensioning ratchet and the tension indicator are inextricably linked. The component length that results from this is not a disadvantage for the formation of the tensioning ratchet. The tension lever still covers the entire length of the respective frame parts, which comprise both the tension lever and the take-up shaft and the associated ratchet wheel and the cocking slide.
This last-mentioned embodiment also has the advantage that it is a safety component that can be removed with a single safety test. Other flanged parts are not intended, so the characteristics of the tensioning ratchet with the integrative tension indicator do not change.
A development of the invention provides that the clamping force indicator, preferably as part of a tensioning ratchet, is used for the use of slacklines. As a result, it can be ensured, for example in school sports, that components on which the slackline is arranged are not overstressed on one side. On the other hand, however, it can also be ensured that the slackline is properly tensioned when the correspondingly predetermined pretension in the line has been reached.
Furthermore, the tension indicator can also be used in sports equipment to be braced, such as stretching bars, uneven bars, horse or the like. This can be ensured even by untrained persons a safe construction of such sports equipment.
Also for secure fixing of objects, such as speakers on carriers on spectator seats, the tension indicator gives the assurance that the lashing has been done correctly with the necessary biasing force.
Further advantageous embodiments will become apparent from the following description, the claims and the drawings.

Description of the embodiments
The inventive tensioning ratchet 1 according to FIGS. 1 to 4 consists of a first frame part 2 and a tensioning lever 3, wherein the tensioning lever 3 is rotatably coupled to a take-up shaft 4. The take-up shaft 4 is further coupled to a ratchet wheel 5, which in turn cooperates with a cocking slide 6, which is slidably disposed in the clamping lever 3. The take-up shaft 4 serves to receive a free end of a lashing strap Z (shown and arranged in front of the take-up shaft 4). To wind this on the take-up shaft 4, the clamping lever 3 is pivoted in and against the direction of arrow 7 about the axis of the take-up shaft 4. During the pivoting movement of the clamping lever 3, the cocking slide 6 slides on the ratchet wheel 5 accordingly, when it is returned to its initial shape shown in Fig. 1. When unfolding the take-up shaft 4 is taken, so that the winding process (and thus the distortion of the cargo to be secured) of the lashing Z is performed.
The first frame part 2 consists of sheets arranged on both sides or metal strips or equivalently designed bodies, which are connected to one another via the take-up shaft 4 and the other via a bolt member 8 rigidly together to form a housing.
According to the invention, a tension indicator 10 is now provided, which according to the invention is part of the tensioning ratchet 1 in a first exemplary embodiment (FIGS. 1 to 4).
The tension indicator 10 consists of a further frame part 11 which is articulated on the bolt element 8 of the tensioning ratchet 1. Preferably, the tension indicator 10 is rotatably coupled to the tensioning ratchet 1.
The further frame part 11 consists of two sheets or sheet metal strips or equivalently designed bodies, a first side part and a further side part, which in turn via the bolt member 8 and another connecting element 12 frame or are connected to each other like a box. On the other frame part 11, a fixed element 13 is arranged in the immediate region on the opposite end of the take-up shaft 4, which also extends from one side of the one side part to the other side part and is arranged stationary. A displaceable in and against the arrow 17 arranged movable member 14 is spring-mounted relative to the stationary member 13. The movable member 14 is a semi-circular in cross-section, cylinder-like member whose ends have bearing elements 19 which cooperate with recesses 20 in the frame part 11, namely with the first side part and the further side part. Both the moving and stationary elements are not dependent on their geometry. Therefore, a variety of cross-sectional shapes are conceivable and the invention is not limited to the given shape. These recesses 20 for the movable element 14 in the frame part are each formed as a longitudinal slot in which the respective bearing element 19 of the movable element 14 slides. One or both free ends additionally have position marks 21 which, with a position mark 22 on at least one side part of the frame part 11, indicate the preload which is at least required for proper lashing. Due to the design of the spring-like mounting of the movable member 14, an accurate indication of the present bias can be specified.
The spring-like mounting of the movable element 14 with respect to the stationary element 13 is achieved by spring elements 15 which are arranged therebetween. The lashing Z is looped with its one end in the tension indicator, such that the loop-like formation 16 of the lashing on the movable member 14 of the clamping force indicator 10 is applied (in particular in Fig. 4 shown).
Now acts a force F, preferably the clamping force in the specified direction of the arrow, so the movable member 14 shifts in the arrow direction such that the spring force provided by the spring element 15 must be overcome.
The spring element 15 is designed such that the movable element 14 moves only in the direction of arrow 17 when the determined by the spring constant of the spring elements spring force is overcome. At a certain distance traveled, the free end of the movable element 14 or its position mark 21 will then reach the position mark 22 on the side part of the further frame part 11. This then means that the minimum necessary preload force is reached.
The spring elements 15 are made of polyurethane and preferably cylindrical. They are fixedly arranged on the movable element 14 and the fixed element 13. They are chosen such that they are capable of indicating the minimum preload force. The polyurethane springs are weather-resistant and can provide their performance at any temperature and after any storage process.
As an alternative to the spring elements described, it is of course also possible to use spiral springs or equivalent means. So it may also be proposed to fill the gap between the fixed and the movable element with an elastic plastic.
The spring elements are shown in more detail, for example in FIG. 5, guided over so-called support elements 25. These support elements 25 are dimensioned in such a way that they engage in the interior of the spring elements 15. Regardless of whether polyurethane springs or other shaped springs, such as coil springs, are used, the support elements engage at least partially in the spring elements and thus prevent slippage of these spring elements 15 within the arrangement between the movable member 14 and the fixed element 13 and on the other hand, a corresponding buckling of the spring elements is also prevented.
However, the support members 25 also have another significant advantage. The support elements 25 are dimensioned in their length such that an overload protection is provided in cooperation with the spring elements. This overload protection is achieved such that between the end faces 26 of the respective opposite support members 25, a distance 27 is provided. This distance corresponds to the maximum travel of the movable element 14 relative to the stationary element 13. This travel also corresponds to the maximum permissible travel of the spring elements 15, so that no plastic deformation can occur within this spring travel. If the permissible prescribed preload force is reached, then these respective opposite end faces 26 of the support elements 25 touch, and the respective spring elements 15 are then out of force. This means that the movable element 14 moves against the fixed element 13 to stop. When overloading thus deformation of the respective other frame parts 11 and a permanent deformation and damage to the spring elements 15 is prevented in a very simple manner.
As can already be seen from the above drawings, the moving element 14 located in the loop of the lashing belt moves relative to the stationary element 13.
The tension force indicator 10 shown in Fig. 5 differs from that in the previous figures in that it has an interface element 23 which is adapted to couple the tension indicator 10 with a tensioning ratchet. In conventional tensioning ratchets, the bolt which is provided for receiving one end of the lashing belt is opened and the tension indicator 10 is flanged. The bolt can be reused, so that the tension indicator 10 and the tensioning ratchet are an element. The loop-like design of the lashing belt, which was previously arranged on the bolt, is now arranged on the movable element 14 of the tension indicator 10.
Preferably, this is done in the way that the loop is slightly increased, so that then this includes the fixed element 13 in addition to the movable member 14. This makes it possible that already used tension ratchets can be retrofitted with the inventive tension indicator 10.
The tension force indicator used in Fig. 5 can also be formed such that it becomes an integral part of a tensioning ratchet 1, as shown in Figs. 6 and 7. The essential difference with respect to the tension force indicator 10 shown in the preceding figures is to be seen in the present invention tension indicator 10 in that the respective other frame parts 11 are integrally formed by the tensioning ratchet 1 and the tension indicator 10. This means that both tensioning ratchet 1 and the tension indicator 10 comprise the same further frame parts 11. The other functional elements, such as the freely movable element 14 or the fixed element 13 and the spring elements 15, which are arranged within the other frame parts 11 of the clamping force indicator 10, are comparable or identical. The lashing strap Z is likewise designed, as shown in FIG. 4, such that it lugs the movable element 14 with its corresponding loop 16. As a result, with a corresponding force F, the movable element 14 can be moved in the direction of arrow 17 with respect to the stationary element 13, so that the display device with the corresponding position mark 21 or 22 indicates the achieved value.
In Fig. 8 the use of the tensioning ratchet 1 with two tension indicator 10 is shown. In a motor vehicle K, a load L is placed on a floor B. It now applies to secure this charge L within the motor vehicle K accordingly.
To perform this backup, the load L is lashed down with lashing straps Z. The number of lashing straps to be used during lashing strongly depends on the coefficient of friction between the bottom of the load L and the top of the bottom B. By additional friction increase by non-slip material, an optimal slip resistance can be additionally achieved. The design depends heavily on the respective conditions of use. The lashing straps are stretched over the load L, wherein one end of the lashing strap is arranged on a first fastening element 30 and another element is arranged on a further fastening element 31 and fixed. By activating the tensioning ratchet V, the lashing strap Z is further fixed above the load L and exerts a corresponding force F in the direction of the arrow 32 due to the present pretension within the lashing strap. This force F in turn acts on the corresponding coefficient of friction, which is increased by the present bias within the lashing Z. The user can now recognize on the basis of the tensioning ratchet 1 according to the invention at the corresponding position markers 21 or 22 that the necessary pretensioning is achieved at least on the side assigned to the fastening element 30. If the lashing strap is properly and correctly placed over the load, the tension indicator 10 will also show the same value. However, if there is a faulty arrangement of the lashing strap, the user can immediately recognize on the basis of the further tension indicator 10 that there is no appropriate lashing of the load. A corresponding action is necessary to eliminate this defect.
