    [0004] Field of the invention
    [0006] The invention is situated in the field of devices that are used to fix to a wall, or other similar flat surface, a tube that has to run along the surface of said wall. In particular, but not limited to, the tubes to which the invention applies are fluid conduits and sheaths for electrical or signal cables.
    [0008] Specifically, the invention refers to a fastening device for fastening a tube to a wall, of the type comprising a support platform to support said fastening device to a wall, a through hole that passes through said support platform for the passage of a fixing element, and at least one open clamp shaped to hold a tube, said clamp comprising two facing arms and a base that is attached to said two arms and that presents an upper face to support said tube.
    [0010] State of the art
    [0012] Clamping devices of this type are known in which the fixing element, to fix the device to a wall, is a screw that passes through the support platform through its through hole. Document WO9723744A1 describes a clamping device of this type, in which the base of the clamp is a band that joins the two arms at the bottom of the clamp and performs a rope function, pulling the two arms when pushed by a tube and thus bringing the ends of said arms next to each other. The ends of the arms are provided with snap closure means that join said ends together when they are brought together. The tube is thus trapped between the arms, which in turn are held in position by the snap closure means. To release the tube, you act on some tabs at the ends of the tubes. arms, so that the closing means release the ends of the arms, which then return to their initial position. In this solution, the tube can be accidentally released by an inadvertent action on the flanges or on the closing means. On the other hand, the closing means arranged at the ends of the spleens constitute a projecting element in which various elements of an installation, such as a cable for example, can be unwantedly hooked.
    [0014] Description of the invention
    [0016] The purpose of the invention is to provide a fastening device for fastening a pipe to a wall, of the type indicated at the beginning, which offers greater security in terms of fixing the pipe and which at the same time allows the pipe to be positioned and fixed in a easy and fast.
    [0018] This purpose is achieved by means of a fastening device for fastening a tube to a wall, of the type indicated at the beginning, characterized in that the base is elastically deformable, and the assembly formed by the base and the two arms is shaped so that the base It can adopt a first stable position, in which the ends of the two arms delimit between them an opening for the introduction of the tube into the clamp, and a second stable position in which said ends of the two arms are closer to each other , with respect to the first stable position, to clamp the tube; and when pressing on the upper face of the base, said base is elastically deformed to pass from the first stable position to the second stable position. The first position and the second position of the base are stable in the sense that, when said base is in one of these positions, the assembly formed by the base and the two arms opposes an elastic deformation of said base tending that said basis drop your assumption. To get the base to go from the first stable position to the second stable position, and vice versa, it is necessary to apply a sufficient force to cause an elastic deformation of said base that makes it go from one position to the other. The operation that the user must carry out to fix a tube is very simple and fast: with the base set in the first stable position, the tube is inserted into the clamp through the opening formed by the ends of the arms, and the upper face of the base is pushed with the tube itself, exerting a sufficient force to cause the elastic deformation of said base and the passage of the latter to the second stable position. Optionally, closure means may be provided to lock the position of the arms. These embodiments with closure means continue to have the advantage that an accidental action on said closure means does not cause an undesired release of the tube, since the latter remains trapped in the clamp as long as a sufficient force is not exerted so that the base leave the second stable position.
    [0020] The arms can have various shapes. For example, each arm can be shaped like an arc of a circle. In preferred embodiments, each of the two arms comprises a wing that extends cantilever from the end of the arm, separating from said arm in the direction of the other arm and the base, each of said wings being configured so that it may undergo elastic flexion to collapse towards the arm from which it extends and apply an elastic force against the tube when the base is in the second stable position. These wings enclose a space between the arms, helping to correctly position the tube when it is inserted into the clamp. Furthermore, because they are elastically applied against the tube, these wings allow to firmly fix tubes of different diameters using the same clamp. Preferably, these wings of the arms are concave, to better engage against the surface of a tube of circular section.
    [0022] In some embodiments, the fixing element, for fixing the fixing device to a wall, can be a screw that is not part of the device and which is placed through the through hole of the support platform. In particular embodiments, intended to dispense with this screw, the fastening device comprises a pin that constitutes the fixing element for fixing said fastening device to a wall, said pin being rigidly attached to the base and aligned with the hole through, and said pin entering said through hole and traversing the support platform when the base passes from the first stable position to the second stable position. This configuration according to the invention allows the user to perform at the same time, with a single gesture, the operation of securing a tube to the device and the operation of securing the device to a wall, and without having to worry about handling any screws. The operation to be carried out by the user is simply to first place the device support platform against the wall, with the through hole aligned with a hole previously made in the wall, and then insert the tube into the clamp and push with said tube the upper face of the base, thus causing the elastic deformation of said base so that it passes to the second stable position. In this operation, the insertion of the pin into the hole in the wall takes place at the same time, to fix the device to the wall, and the approach of the ends of the arms to clamp the tube. If necessary, and depending on the nature of the wall and the shape of the pin, a plug is previously inserted into the hole in the wall.
    [0024] Preferably, the base comprises a rigid central section to which an upper end of the spike is attached, and said rigid central section of the base moves integrally with said spike towards the support platform when the base passes from the first stable position to the second stable position. This configuration, in which the pin moves integrally with the base in the same direction in which the latter is pushed by the tube, provides high robustness and a precise movement of the pin in the axial direction of the through hole.
    [0026] The clamping device optionally comprises a plug rigidly attached to the support platform. The plug comprises an inner passage and extends from said support platform such that said inner passage extends the through hole and is aligned with the pin. The spike and the plug are shaped such that said spike is pressed into said inner passage of the plug, through said through hole, when the base passes from the first stable position to the second stable position. This configuration makes fixing the device to the wall even easier. The operation to be carried out by the user simply consists of first placing the device support platform against the wall, inserting the plug into a hole previously made in the wall. Preferably, the hole is dimensioned so that the insertion of the plug into it is adjusted. The device is held in place by the plug inserted into the drill, so that the user does not have to worry about keeping the device in place on the wall. Subsequently, the user can perform the operation of inserting the tube into the clamp and pushing the base with said tube, causing the elastic deformation of said base to move to the second position. The pin is thus inserted into the plug and fixes the device to the wall, at the same time as the arms move closer to each other and clamp the tube.
    [0027] The plug integrated in the fastening device can be of different types, depending on the characteristics of the wall on which said device is to be fixed. For example, it can be a nailing plug, which opens in two parts when the spike is inserted, a retractable plug, which deforms by folding back on itself when the spike is inserted, or an expansion plug, which expands when it is inserted. insert the spike. In preferred embodiments, the plug is an expansion plug, which expands radially with respect to the axis of the inner passage when the pin is pressed into said inner passage.
    [0029] Preferably, the clamping device comprises two inclined pillars that extend from the support platform, separating from each other and delimiting a space between them. Each of the two pillars is joined at one end to each of the two arms by an elastically flexible elbow. The base has an arched bridge shape, which extends above said space, when said base is in the first stable position, and a concave cradle shape, which enters said space, when said base is in the second stable position. . This configuration provides good stability of the two positions of the base. In addition, in cases where the clamping device is not provided with the pin, so that the user must use a fixing screw, the space delimited between the two posts and the base, in the first stable configuration of the base , allows the screw to be positioned laterally to subsequently insert it into the through hole of the support platform. This eliminates the need to insert the screw through a through hole made in the base. In preferred embodiments, the base is a continuous strip with no through holes, which provides greater robustness and reliability. Furthermore, the absence of through holes in the continuous band that forms the base provides a free surface on the upper face of said base, which can be used to put an indication, such as a clamp gauge, which is visible by the user even when the clamping device is fixed to a wall.
    [0031] In preferred embodiments, the base comprises first rigid lateral sections, each one extending a lower end of one of the arms, second rigid lateral sections, each one being joined to one of said first rigid lateral sections by means of a first joining zone, and a rigid central section joined at each of its two ends to one of said second sections rigid sides by means of a second joining zone. Each of said first and second joint zones is a zone of reduced thickness that constitutes a hinge joint by elastic deformation. This constructive solution has the advantage of being simple and robust.
    [0033] Preferably, the construction device is a one-piece body of polymeric material.
    [0035] The invention also comprises other features of detail shown in the following detailed description of an embodiment of the invention and in the accompanying figures.

    [0052] Detailed description of some embodiments of the invention
    [0054] Figs. 1 to 5 show a first embodiment, in which the fastening device is designed to be fixed to a wall by means of a screw (not shown in the figures) that is not part of the device and that is placed through the through hole of the support platform.
    [0056] The clamping device 1 is a one-piece molded body of polymeric material, for example a thermoplastic such as PVC, polyamide or polypropylene. The clamping device 1 comprises a support platform 2 and an open clamp 4 for clamping a tube. The support platform 2 has a flat lower face 23, intended to rest on a wall to which the fastening device 1 is fixed, and a through hole 3 that passes through said support platform 2, intended for the passage of a fixing element which in this case is a screw (not shown). The clamp 4 is formed by two arms 5 facing each other and a base 6 that is connected to said two arms 5 and that has an upper face 61 to receive a tube. Each of the two arms 5 has a concave wing 9 that extends cantilever from the end 7 of said arm 5, separating from the latter in the direction of the other arm 5 and the base 6. The wings 9 have a curved band shape of small thickness, so that they are elastically flexible. The bracket 4, formed by the two arms 5 and the base 6, is attached to the support platform 2 by means of two inclined pillars 14 that extend from said support platform 2, separating one from the other and delimiting a space between them. 15. Each of the two pillars 14 is joined at one end to each of the two arms 5 by an elastically flexible elbow 16.
    [0057] The base 6 has a continuous band shape that extends between the two arms 5. More specifically, in the embodiment represented in the figures, the base 6 comprises first rigid lateral sections 19, each one extending a lower end of one of the arms 5, some second rigid lateral sections 20, each one of them joined to one of said first rigid lateral sections 19 by means of a first joining zone 21, and a rigid central section 11 joined by each of its two ends to one of said second rigid lateral sections 20 by means of a second joining zone 22. Each of the first and second joining zones 21, 22 is a zone of reduced thickness that constitutes a hinge joint by elastic deformation.
    [0059] Thanks to this configuration, the base 6 is elastically deformable, so that it can adopt a first stable position, shown in Figs. 1 to 3, in which the ends 7 of the two arms 5 delimit between them an opening 8 for the introduction of a tube 30 into the clamp 4, and a second stable position, shown in Figs. 4 and 5, in which the ends 7 of the two arms 5 are closer to each other, with respect to said first stable position, to trap the tube 30. In the first stable position, the base 6 has a bridge shape arched 17, which extends above the space 15 delimited laterally by the pillars 14, while in the second stable position, said base 6 forms a concave cradle 18 that enters said space 15.
    [0061] In the embodiment represented in the figures, the continuous band that forms the base 6 is devoid of through holes. The space 15 under the arched bridge 17, in the first stable position, allows a fixation screw to be inserted laterally. In other possible embodiments (not represented in the figures), the continuous band that forms the base 6 has through holes, in particular said continuous band can have a through hole suitable for the passage of a fixing screw.
    [0063] The use of the clamping device 1, to clamp a tube 30 to a wall, is as follows. Initially, the clamping device 1 is with its base 6 in the first stable position shown in Fig. 1, in which the ends 7 of the arms 5 are separated and delimit an opening 8 to enter a tube in the clamp. 4. The user fixes the fastening device 1 to a wall by means of a screw that passes through the through hole 3 of the support platform 2. Because the base 6 forms an arched bridge 17 above the space 15, the user can easily attach screw introducing it laterally into said space 15 and subsequently passing it through the through hole 3. In other possible embodiments (not shown in the figures), the base 6 has a through hole that passes through the upper face 61 and allows the passage of a screw Fixing. Once the clamping device 1 has been fixed to a wall, the user inserts the tube 30 into the clamp 4 through the opening 8 and moves said tube 30 in the direction of the support platform 2, pushing with said tube 30 the base 6 by its upper face 61. If the pressure exerted by the tube 30 on the upper base 61 of the base 6 is sufficient, the base 6 leaves the first stable position, is elastically deformed and passes to the second stable position. In this second stable position, the tube 30 is trapped between the arms 5. More precisely, the tube 30 is trapped between the wings 9 of the arms 5. As can be seen by comparison between Figs. 1 and 5, the wings 9 engage against the tube 30 and undergo an elastic bending, bending towards the arm 5 from which they extend. The wings 19 thus apply an elastic force against the tube 30 when the base 6 is in the second stable position. Other embodiments are possible in which the arms 5 are devoid of wings 9, in which case it is the arms 5 themselves that come into contact with the tube 30.
    [0065] To release the tube 30 from the position shown in Fig. 5, the user can separate the arms 5 by exerting a sufficient force on them so that the base 6 leaves the second stable position, becomes elastically deformed and returns to the first stable position. This force to separate the arms 5 can be carried out by acting directly on them, for example by separating them by hand, or by pulling the tube 30 in the direction away from the support platform 2.
    [0067] Figs. 6 to 10 show a second embodiment, in which the fastening device is designed to be able to be fixed to a wall without the need to use a screw, and so that the user can simultaneously carry out the operation of clamping a tube to the device and the operation of fixing the device to a wall.
    [0069] This second embodiment is completely the same as the first, except for the characteristics described below. The fastening device 1 comprises a plug 12 rigidly attached to the support platform 2 and intended to be inserted into a hole in the wall, and a pin 10 that is rigidly attached to the base 6 and that constitutes the fastening element, to fix the fixture 1 to a wall. As will be seen in
    [0072] Thereafter, the pin 10 moves integrally with the base 6 and is inserted into the plug 12 through the through hole 3 of the support platform 2.
    [0074] The plug 12 extends from the support platform 2 and has an internal passage 13 that extends the through hole 3 and is aligned with the spike 10. The plug 12 is an expansion plug, which expands radially with respect to the axis el inner passage 13 when the pin 10 is pressed into said inner passage 13.
    [0076] The pin 10 is connected at an upper end to the rigid central section 11 of the base 6, so that said pin 10 moves integrally with said central section 11. When the base 6 passes from the first stable position (Figs. 6-8 ) to the second stable position (Figs.
    [0077] 9-10), the pin 10 passes through the support platform 2 through the through hole 3 and is pressed into the inner passage 13 of the plug 12.
    [0079] As in the first embodiment, the clamping device 1 shown in Figs.
    [0080] 6-10 is a one-piece molded body of polymeric material, for example a thermoplastic such as PVC, polyamide or polypropylene.
    [0082] The use of the clamping device 1 according to this second embodiment is as follows. Initially, the clamping device 1 is with its base 6 in the first stable position shown in Fig. 6, in which the ends 7 of the arms 5 are separated, delimiting an opening 8 to enter a tube into the clamp 4. , and the pin 10 is outside the plug 12 in space 15. The user places the clamping device 1 against the wall, inserting the plug 12 into a corresponding hole made in the wall. Once the clamping device 1 has been fixed to the wall, the user inserts the tube 30 into the clamp 4 through the opening 8 and moves said tube 30 in the direction of the support platform 2, pushing with said tube 30 the base 6 by its upper face 61. If the pressure exerted by the tube 30 on the upper base 61 of the base 6 is sufficient, the base 6 leaves the first stable position, is elastically deformed and passes to the second stable position, and at the same time the pin 10 passes through the support platform 2 through the through hole 3 and is inserted under pressure into the inner passage 13 of the plug 12. The tube is trapped between the wings 9 of the arms in the same way described above for the first embodiment. The difference is that, in this case, the movement of the tube 30 simultaneously causes the passage of the base 6 to the second position stable, to clamp the tube 30 between the arms 5, and the insertion of the pin 10 into the inner passage 13 of the plug 12 to fix the clamping device 1 to the wall.
    [0084] It is possible to release the tube 30 again, proceeding as in the first embodiment. The difference is that when the base 6 returns to the first stable position, in addition to the release of the tube 30, there is a release of the clamping device 1 with respect to the wall, since the pin 10 comes out of the inner passage 13 of the plug 12 In Figs. 6-10 the pin 10 has a smooth surface, but other embodiments are possible in which the pin 10 has retaining projections. Embodiments are also possible in which the clamping device has the pin 10 but does not have the plug 12. In this case, the pin 10 is inserted into a plug that is not part of the clamping device and has been previously inserted. in a hole in the wall.
