Abstract

The present invention relates to a shim (100) having a thickness that can be adjusted by means of an actuator device. Actuating the actuator device causes a movement of a sliding element (20) inside a housing (10) in a first direction (101). The movement of the sliding element (20) causes a movement of a movable element (30) in a second direction (102), thus increasing the distance between an outer wall (34, 84, 94) of the movable element (34) and a bottom wall (13) of the housing (10), and thus increasing the thickness of the shim (100).

Description

Adjustable spacer

Technical area

The present invention relates to a wedge whose thickness is adjustable by a user. Prior art

[0002] The document KR20110134578A describes a shim of variable thickness making it possible to control the horizontal of a door frame under construction. In this known device, horizontal plates can be moved away from each other by pushing lifting elements apart with the aid of a screw. [0003] A problem with this known device is that one of the horizontal plates must rest on a flat surface, otherwise the various parts of the device separate, and it can therefore only be used for a vertical thickness adjustment.

The document CN102620120A describes an adjustable sizing locking device. In this device, when sliding elements approach a cylinder, they raise a movable element. [0005] The document DE102006012390A1 describes an adjustable wedge for the installation of doors or windows.

[0006] The document W02020/011846A1 describes a spacer making it possible to adjust a theoretical spacing between two components.

Summary of the invention

An object of the present invention is to provide an adjustable shim which can be used to adjust a vertical thickness or a horizontal thickness. [0008] To this end, the invention proposes a wedge comprising:

• a box comprising: o a front wall, o a rear wall, opposite the front wall in a first direction, o a bottom wall, and o an opening, opposite the bottom wall in a second direction perpendicular to the first direction;

• a sliding element located, at least partially, in the housing, and configured to move relative to the housing in the first direction and to be blocked by the housing in a third direction perpendicular to the first direction and to the second direction;

• a movable element configured to pass through the opening, comprising an outer wall opposite the bottom wall in the second direction, and configured to be moved in the second direction by the sliding element when the sliding element moves relative to the housing in the first direction, and to be blocked by the housing in the third direction; and

• an actuator device allowing a user to move the sliding element in the first direction relative to the housing, so as to move the movable element in the second direction; characterized in that it comprises a retaining mechanism configured to retain the movable element and the sliding element at least partially in the housing and in a fixed position relative to the housing in the absence of actuation of the actuator device, and to allow movement of the sliding element in the first direction and movement of the movable element in the second direction upon actuation of the actuator device.

The wedge according to the invention operates as follows. The user actuates the actuator device, which moves the slider in the first direction. The movement of the sliding element generates a push or a pull on the mobile element, which moves in the second direction. Since the movable element passes through the opening, it deviates or then approaches the bottom wall of the housing. Thus, the thickness of the wedge, given by the distance between the bottom wall of the casing and the outer wall of the movable element, can be adjusted by actuating the actuator device. Thanks to the retaining mechanism, the different elements remain together, without relative movement, before activating the wedge. This allows the thickness of the wedge to be fixed before any actuation.

[0010] As the housing prevents the movements of the sliding element and of the movable element in the third direction during their respective movements, it is possible to adjust a horizontal thickness by placing the wedge so that the third direction either vertical.

In the context of this document, the front of the wedge is the side of the wedge facing the user actuating the actuator device.

[0012] The wedge can be made so as to be light enough to hold between two vertical surfaces, and inexpensive enough to be disposable.

A wedge according to the invention can be offered in several models of different lengths because different lengths (in the first direction) make it possible to obtain ranges of different thicknesses (in the second direction).

[0014] According to one embodiment of the invention, the sliding element comprises a rear wall which is oblique with respect to the first and second directions, and the mobile element comprises a front wall which is oblique with respect to the first and second directions and configured to slide on the rear wall of the slider. The obliqueness allows the front-rear movement in the first direction of the sliding element to cause movement of the mobile element in the second direction. The driving of the movable element by the sliding element could be achieved in another way while remaining within the scope of the invention.

According to one embodiment of the invention, the sliding element and the movable element are locked relative to each other according to the third direction by a locking mechanism located on the sliding element and/or the mobile element. This makes it possible to reduce the risks of a relative movement of the mobile element with respect to the sliding element in the third direction.

According to one embodiment of the invention, the locking mechanism comprises a projecting plate located on the sliding element and perpendicular to the third direction, and a slot located on the movable element and arranged to receive, at the less partially, plate. The slot extends in the first direction so that the plate can move in the slot when the actuator device is actuated. The blocking mechanism could be reversed, with a plate located on the movable element and the slot on the sliding element.

According to one embodiment of the invention, the actuator device comprises a front hole passing through the front wall, and a rod passing through the front hole and having a first end intended to push and/or pull the sliding element and a second end, located outside the housing, and intended to be actuated by the user. As the second end of the rod protrudes from the housing, it is easy to adjust the thickness when the wedge is in place.

The actuator device can be arranged differently. For example, it could include a self-locking mechanism that only allows the thickness to be increased and not reduced.

According to one embodiment of the invention, the rod comprises a thread corresponding to the front hole, and in which the length of the housing is greater than or equal to the sum of the length of the sliding element and the length of the net. The difference between the length of the casing (that is to say its internal length) and the length of the sliding element is the maximum amplitude of the displacement of the sliding element in the first direction. The fact that this maximum amplitude of displacement is equal to or greater than the length of the net makes it possible to prevent the user from driving the rod too far into the housing, which could push the slider against the rear wall, with the risk of the slider coming out of the housing or breaking the wedge.

[0020] According to one embodiment of the invention, the housing comprises fixing elements allowing the rear wall to be attached to a first surface or to a second surface outside the wedge. For example, the housing may include adhesive to bond the back wall to the exterior surface, and/or holes in the back wall and/or tabs to screw the back wall against the first surface.

[0021] According to one embodiment of the invention, the entire sliding element moves away from the front wall and approaches the rear wall when it is moved by the actuator device. Such a configuration allows a particularly simple and robust architecture of the hold.

According to one embodiment of the invention, the movable element is configured to be blocked by the rear wall of the housing in the third direction. This avoids having to introduce other elements into the hold, which would increase its complexity.

According to one embodiment of the invention, the retaining mechanism comprises a first part located on a first wall and a second wall of the housing and a second part located on the movable element; the first and second walls of the housing being perpendicular to the third direction. This makes it possible to block the mobile element to the left and to the right, and therefore to retain it particularly well.

[0024] According to one embodiment of the invention, the first part of the retaining mechanism comprises protrusions located on the first wall and the second wall of the housing, and the second part of the retaining mechanism comprises recesses located on a first wall and a second wall of the movable element, and provided to receive the protrusions; the first and second walls of the movable element being perpendicular to the third direction; the wedge being configured so that the protrusions move apart when the movable element is moved by the sliding element. The protuberances are on the internal face of the first and second walls of the casing. Thus, without actuation, the protrusions remain in the recesses, but if the actuator is actuated, the movable element is pushed in the third direction and this push has the effect of separating the protrusions and allowing movement. The sliding element being located between the movable element and the bottom wall of the casing, it is also retained by the interlocking of the protuberances in the recesses. The protuberances can for example be teeth.

According to one embodiment of the invention, the movable element comprises a main element configured to be moved by the sliding element, and a first removable element configured to be removably fixed to the main element and to increase the thickness of the movable element in the second direction. The external wall of the mobile element can then be a support wall for the main element if the removable element is not present, or a support wall for the removable element if it is present. The thickness adjustment can then be made in two combinable ways: at least one removable element provides a thickness, which can be varied (by omitting the first removable element, by attaching an additional removable element to it and/or by replacing it with a removable replacement element) and the displacement of the movable element provides another thickness, which can also be varied (by actuating the actuator device). Preferably, the variation in thickness originating from the displacement of the movable element allows finer adjustment than the variation in thickness originating from the removable element.

According to one embodiment of the invention, the removable attachment between the main element and the first removable element comprises a tenon and a mortise. The tenon and the mortise preferentially extend along the first direction. They are preferably provided for sliding according to the first direction and a blocking according to the second and the third direction. This allows the first removable element to be slid over the main element when the housing, the sliding element and the main element are already in the space between the first and second surfaces.

According to one embodiment of the invention, the wedge comprises an additional removable element configured to be removably fixed to the first removable element and to increase the thickness of the movable element in the second direction. It is thus possible to superimpose removable elements in order to obtain a great thickness.

The invention also relates to an assembly comprising the wedge comprising the main element and the first removable element, and at least one replacement removable element configured to be fixed to the main element in place of the first removable element, the replacement removable element and the first removable element having different thicknesses. The assembly thus comprises a set of at least two removable elements. This gives a wide range of possible thicknesses.

The invention also relates to a kit comprising a wedge and a holding element comprising two clamps fixed to a rigid rod and configured to hold the two vertical uprights of a door at a fixed distance from each other. .

The invention also relates to a method of using a wedge, the method comprising the following steps:

• placing the wedge in a space between a first and a second surface; and

• operate the actuator device until the bottom wall is against the first surface and the outer wall is against the second surface. [0031] Preferably, the housing is fixed relative to the first surface during actuation of the actuator device. It can for example be fixed to the first surface.

[0032] The first surface is for example on a door jamb, frame, frame, and the second surface on a wall. The first surface is for example any element requiring precise and easy mounting.

[0033] For a door, the method can be carried out for several wedges, for example, two wedges for each vertical upright, and optionally one wedge for the horizontal upright. Thus, the installation of a frame may require the use of at least four or five wedges.

[0034] Once the wedges have been adjusted so that the vertical uprights are placed vertically and the horizontal upright is placed horizontally, the rods of the actuator devices can be broken or removed, so as not to protrude forward from the uprights of the door. A foam can then be dispensed between the frame and the wall. The wedges will then be embedded in the foam.

The invention also relates to a method of using a wedge comprising the main element and the first removable element, the method comprising the following steps:

• placing the housing, the sliding element and the main element in a space between a first and a second surface;

• attach the first removable element to the main element; and

• actuate the actuator device until the bottom wall is against the first surface and the outer wall is against the second surface.

[0036] The first removable element can be attached to the main element while the housing is still outside the space between the surfaces, or when the housing is already in the space between the surfaces. Brief description of figures

Embodiments of the Invention

The present invention is described with specific embodiments and references to figures, but the invention is not limited thereby. The drawings or figures described are only schematic and are not limiting. Furthermore, the functions described can be performed by other structures than those described in this document. [0039] In the context of this document, the terms "first" and "second" only serve to differentiate the various elements and do not imply an order between these elements.

In the figures, identical or similar elements may bear the same references.

[0041] Figure 1 schematically illustrates a door frame 300 wedged into the hole in a wall by four wedges 100. The door frame 300 comprises two vertical uprights 301 and a horizontal upright. The vertical uprights 301 are held at a distance from each other thanks to two holding elements 200 comprising two clamps or jaws 201 fixed to a rigid rod 202. The wedges 100 are located in a space 310 between the frame 300 and the wall. The wedges 100 according to the invention comprise a housing 10, a sliding element 20, a movable element 30, and an actuator device. Possible embodiments of these elements are described with reference to the following figures with reference to a first 101, a second 102 and a third 103 direction, which are mutually perpendicular. The adjustable thickness thanks to the wedge 100 is the extent of the wedge 100 along the second direction 102.

[0042] Figure 2 illustrates a possible embodiment of the housing 10. It preferably comprises a front wall 15 and a rear wall 16 perpendicular to the first direction 101, a bottom wall 13 perpendicular to the second direction 102, an opening 11 in a plane perpendicular to the second direction 102, and a first wall 17 and a second wall 18 perpendicular to the third direction 103. The side 14 of the case opposite the bottom wall 13 may be present and crossed by the opening 11, or be absent.

The front wall 15 and the rear wall 16 are spaced apart by a length 12 in the first direction 101. The front wall 15 is traversed by a front hole 51, preferably threaded, forming part of a possible embodiment of the actuator device. The housing 10 can comprise at least a fixing hole 60, located in the bottom wall 13 and/or in the tabs 61. The holes 60 in the tabs 61 are preferred to the holes 60 in the bottom wall 13 because the placement of the latter requires removing the sliding element 20 and the movable element 30.

The length 12 of the housing 10 is preferably between 4 cm and 15 cm. The width of the box 10 is preferably between 2 cm and 4 cm. The thickness of the case 10 is preferably between 2 cm and 4 cm.

[0045] Figures 3a and 3b illustrate a possible embodiment of the sliding element 20. It preferably comprises a front wall 25 perpendicular to the first direction 101, a bottom wall 23 perpendicular to the second direction 102, and a first wall and a second wall 28 perpendicular to the third direction 103. It also comprises a rear wall 26 oblique with respect to the first 101 and second 102 directions, so that it has a thickness, in the second direction 102, greater at the front than rear.

The sliding element 20 is configured to be, at least partly, in the housing 10, so that its first wall slides along the first direction 101 against the first wall 17 of the housing 10, and is blocked according to the third direction 103 via the first wall 17 of the casing 10; so that its second wall 28 slides in the first direction 101 against the second wall 18 of the casing 10 and is blocked in the third direction 103 by the second wall 18 of the casing 10; and that its bottom wall 23 slides in the first direction 101 against the bottom wall 13 of the box 10 and is blocked in the second direction 102 by the bottom wall 13 of the box 10.

The length 22 of the sliding element 20, in the first direction 101, is less than the length 12 of the housing 10. It can preferably slide in the housing between a first position in which its front wall 25 is blocked by the front wall 15 of housing 10, and a second position in which the end of its rear wall 26 is blocked by the rear wall 16 of the housing 10.

[0048] The thickness of the sliding element 20, in the second direction

102, is preferably equal to or less than the thickness of the casing 10. The width of the sliding element 20, in the third direction 103, is preferably less than equal to the internal width of the casing 10. The sliding element 20 may comprise a plate 71, projecting from the rear wall 26. The plate 71 is arranged to engage movably along the first direction 101 and the second direction 102, in a slot 72 of the movable element 30, thus forming a blocking mechanism blocking the sliding element 20 and the movable element 30 in the third direction 103.

The sliding element 20 may include a recess 52 aligned with the front hole 51 and forming part of a possible embodiment of the actuator device.

[0051] Figure 4 illustrates a possible embodiment of the movable element 30. It preferably comprises a rear wall 36 (visible in Figure 9) perpendicular to the first direction 101, a bottom wall 33 perpendicular to the second direction 102, and a first wall 37 (visible in figure 9) and a second wall 38 perpendicular to the third direction

103. It also comprises a front wall 35 oblique with respect to the first 101 and second 102 directions, so that it has a thickness, in the second direction 102, greater at the rear than at the front. It also includes a support wall 34 opposite the bottom wall 13 of the box 10 and located outside the box 10. It can also include an additional wall 39, making the junction between the front wall 35 and the wall of support 34. It may also include a flat slot 72 extending along the first 101 and second 102 directions. The length, along the first direction 101, of the bottom wall 33 is preferably smaller or equal to amplitude of movement of the movable element 20 in the first direction 101 .

The movable element 30 is configured to be engaged in the housing 10, so that its first wall slides in the second direction 102 against the first wall 17 of the housing 10, and is locked in the third direction 103 by the first wall 17 of the housing 10; that its second wall 38 slides in the second direction 102 against the second wall 18 of the casing 10 and is blocked in the third direction 103 by the second wall 18 of the casing 10; and so that its rear wall 36 slides in the second direction 102 against the rear wall 16 of the casing 10 and is blocked in the first direction 101 by the rear wall 16 of the casing 10. part of a possible embodiment of the actuator device. The rod 53 is designed to pass through the hole 51 and so that its thread 56 fits into the thread of the hole 51. Its first end 54 is located in the housing 10 and is intended to push and/or pull the sliding element 20. Its second end 55, opposite the first end 54 in the first direction 101, is located on the other side of the front wall 15 and is intended to be actuated by the user.

The first end 54 can for example be received in the recess 52 and/or be fixed to the sliding element 20. It preferably comprises a recess 58 followed by a widening 59 so that the widening is located in the recess 52 and can pull the sliding element 20 towards the front wall 15.

The second end 55 is preferably arranged to be able to be turned by hand, without a screwdriver, for example thanks to a T-shape. The second end 55 is preferably arranged to be able to be broken, so as to reduce the length of the wedge 100 along the first direction 101. In one embodiment of the invention, the length 57 of the thread 56 of the rod 53 is less than or equal to the difference 107 between the length 12 of the housing 10 and the length 22 of the sliding element 20 (visible Figure 6a). [0057] Figures 6a to 6c illustrates a mode of operation of a wedge 100 according to one embodiment of the invention. The wedge 100, as illustrated in Figure 6a, is placed in a space 310 between a first 302 and a second 303 surfaces which face each other in the second direction 102, so that the second end 55 of the rod 53 is towards the user. Figures 6b and 6c illustrate what happens when the user moves the rod 53 in the first direction 101, from front to rear. The first end 54 of the rod 53 pushes the sliding element 20 along the first direction 101, from front to rear. The rear wall 26 of the sliding element 20 pushes the front wall 35 of the movable element 30. Given the obliqueness of the walls 26, 35, and as the movable element 30 is blocked in the first direction 101 by the rear wall 16 of the housing 10, the front wall 35 of the movable element 30 slides against the rear wall 26 of the sliding element 20, and the movable element 30 moves in the second direction 102, away from the wall of bottom 13. Its bearing wall 34 (or 84 or 94 as described below), which forms its outer wall, can then move closer to the second surface 303. If the user lets go of the rod 53, the movable element 30 remains in place. If the user moves the rod 53 from the back to the front, the movable element 30 can move closer to the bottom wall 13 so as to reduce the thickness of the wedge 100.

[0058] Figures 7a to 7c illustrates a mode of operation of a wedge 100 according to another embodiment of the invention. In this embodiment, the sliding element 20 comprises an additional wall 29, making the junction between the rear wall 26 and the bottom wall 23 and able to abut against the rear wall 16 of the box 10. The additional wall 29 can be perpendicular to the first direction 101. The embodiment of FIGS. 7a to 7c allows better stability of the wedge than the mode of embodiment of Figures 6a to 6c, in particular in the maximum position illustrated in Figures 6c and 7c. The slope of the rear wall 26 being lower in the embodiment of Figures 7a to 7c than in the embodiment of Figures 6a to 6c, the latter allows greater variability in the thickness of the wedge 100.

Figure 8 is another illustration of slider 20 of Figures 7a-7c.

[0060] Figure 9 illustrates another possible embodiment of the movable element 30, in which the movable element 30 comprises a main element 80 in contact with the sliding element 20, and a first removable element

90 which can be removably fixed to the main element 80. The main element 80 comprises a bearing wall 84, perpendicular to the second direction 102, which forms the outer wall of the wedge 100 if the first removable element 90 is absent.

The first removable element 90 comprises a bearing wall 94, perpendicular to the second direction 102, and which forms the outer wall of the wedge 100 if the first removable element 90 is present. It also includes a bottom wall 93 opposite the support wall 94 and in contact with the main element 80.

[0062] The removable attachment between the main element 80 and the first removable element 90 comprises a mortise 81 and a tenon 91, respectively located on the support wall 84 of the main element 80 and on the bottom wall 93 of the first removable element 90, or vice versa. Mortise 81 and tenon

91 preferably have a parallelogram shape in a plane perpendicular to the first direction 101 .

An assembly according to the invention may comprise several removable elements including the first removable element and other removable elements that can be put in its place and have different thicknesses, in the second direction 102. [0064] Figure 10 illustrates a variant of the main element 80. It could for example be suitable for the embodiment of the wedge 100 illustrated in Figures 7a to 7c.

[0065] Figures 11 and 12 illustrate that removable elements can also be provided to attach to each other. The first removable element 90 can for example be as illustrated in FIGS. 11 and 12 and comprise a tenon 91 on the bottom wall 93 and a mortise 92 on the support wall 94. The mortise 92 makes it possible to fix a removable element additional 99. The first removable element 90 and the additional removable element 99 can be of the same thickness or of different thicknesses.

Each removable element preferably has a thickness of between 0.5 cm and 4 cm.

[0067] Figures 13a and 13b illustrate an example of housing 10 and main element 80 in an embodiment of the invention comprising a retaining mechanism. The retaining mechanism makes it possible to fix the movable element 30 and the sliding element 20 to the housing 10 in the absence of actuation of the actuator device, and allows movement of the sliding element 20 in the first direction 101 and movement of the movable element 30 in the second direction 102 during actuation of the actuator device.

The retaining mechanism may for example comprise protuberances 41 on the internal faces of the first 17 and the second 18 walls of the housing 10, and recesses, for example slots, 42 in the external faces of the first 37 and the second 38 walls of the movable element 30. Initially, the protuberances 41 are in the recesses 42, which blocks the movable element 30 in the second direction 102. As the sliding element 20 is partly between the element mobile 30 and the bottom wall 13 in the second direction, it is also blocked. When the actuator device moves the sliding element 20 from the front to the rear, the pressure exerted by the movable element 30 to move away from the bottom wall causes the protrusions 41 to move apart, and therefore allows movement in the second direction 102.

The rod 53 is preferably metallic. The other elements of the wedge 100 are preferably made of polymer (for example PVC), of wood and/or of metal. The casing 10 can be a bent sheet.

[0070] In the example of use illustrated in Figure 1, the bottom wall of the boxes is fixed to the first surface 302, which is the outer surface of the vertical uprights 301, and the outer wall 94 of the first removable element 90 is against the second surface 303, which is the surface of the wall. The attachment could be reversed while remaining within the scope of the invention. The user can place the wedges 100, and, in order to adjust the verticality of the vertical uprights, adjust the thicknesses of the wedges 100 by replacing the first removable element 90 with a replacement element and/or by adding an additional removable element 99 and /or by actuating the actuator device. Then he breaks or removes rod 53 and injects foam into space 310.

[0071] A shim could also be placed in the gap between the lintel and the horizontal upright of the door and so as to adjust the horizontality of the horizontal upright.

In other words, the invention relates to a wedge 100 whose thickness can be adjusted using an actuator device. An actuation of the actuator device causes a movement of a sliding element 20 in a housing 10 and in a first direction 101. The movement of the sliding element 20 causes a movement, in a second direction 102, of a movable element 30, thus increasing the distance between an outer wall 34, 84, 94 of the movable element 34 and a bottom wall 13 of the casing 10, and therefore the thickness of the wedge 100.
