Description

[0001] The present invention relates to an installation for maintaining a two- or three-wheeled rolling machine in an upright position for the purpose of intervention on said machine.

[0002] It relates in particular to an installation for holding a two- or three-wheeled rolling machine for the purpose of an intervention on said machine, said installation comprising an elongated platform extending longitudinally from one end towards the opposite end and having two opposite faces and a first holding device having at least two jaws capable of forming a vise to allow a vise grip on at least one wheel of the machine.

[0003] Such an installation is known as illustrated by patent EP-3,543,199.

[0004] Maintenance or technical inspection of a two- or three-wheeled vehicle, such as a motorcycle, generally requires, when the vehicle is upright, partially lifting it, either at the front or rear wheel, to perform the work. Traditionally, the front wheel is clamped in a fixed wheel clamp, and a jack is used underneath the vehicle, or a hoist is used from above to lift the rear. Lifting the front of the vehicle is a more precarious operation. This involves clamping the front wheel in a front wheel clamp, strapping the rear of the vehicle to the lift, and then using a jack or hoist to slightly lift the front of the vehicle after releasing the front wheel from the clamp. This maneuver places the vehicle in an unstable position. Therefore, solutions offering increased safety are being sought.

[0005] One aim of the invention is to provide an installation of the aforementioned type whose design allows easy and safe intervention on the machine without harming productivity.

[0006] To this end, the invention relates to an installation for holding a two- or three-wheeled vehicle for the purpose of intervention on said vehicle, said installation comprising an elongated platform extending longitudinally from one end towards the opposite end and having two opposite faces and a first holding device having at least two jaws capable of forming a vise to allow a vise grip on at least one wheel of the vehicle, characterized in that the installation comprises a second holding device, in that the first and second holding devices are disposed, one at one end, the other at the other end of the so-called top face of the platform, in that the second holding device is mounted removably on the platform,in that the second holding device comprises a first jaw and a second jaw positionable opposite each other in a direction transverse to a longitudinal axis of the plate, in that the first and second jaws each comprise a so-called fixed part which, when coupled to the plate, is stationary, and a movable part mounted to slide relative to the fixed part in the direction of bringing the other jaw closer or further away when positioned opposite said first and second jaws, with the movable parts of the first and second jaws arranged between the fixed parts of the first and second jaws,in that the moving part of the first jaw is connected to the fixed part of said first jaw by a drive device comprising a screw / nut assembly to allow, in the driven state of rotation of the screw, an axial displacement of the moving part, and in that the moving part of the second jaw, which in the coupled state of the jaws to the plate has a surface called the front opposite the first jaw and an opposite surface called the back, is equipped with at least two parallel guide axes extending outward from the back of the moving part, these guide axes, configured to insert at one end into a bearing of the fixed part of said second jaw, being beveled over at least part of their length to form an axis of increasing thickness from their insertion end into the bearing towards their connection zone to the back of the moving part,Each bearing is equipped with a shaft locking device within the bearing, designed to make contact with the shaft's bevel. A second holding device, designed to clamp the rear wheel of the machine, allows for easy lifting of the front of the machine. The removable mounting of this second holding device on the platform ensures unobstructed access to the machine. The jaw design of the second holding device allows for quick locking to avoid impacting productivity. Naturally, the screw / nut assembly is irreversible. Therefore, applying pressure to the moving part of the first jaw does not cause the screw to rotate. The friction angle between the nut and the screw is greater than the screw's helix angle.

[0007] According to one embodiment of the invention, the plate is provided with through holes, and the fixed parts of the first and second jaws of the second holding device are each equipped with at least two tabs, each insertable into a hole in the plate, for holding the fixed part in a stationary position. Securing the fixed parts of the jaws to the plate with simple tabs allows this operation to be performed easily and without tools.

[0008] According to one embodiment of the invention, each leg of the first or second jaw forms, either alone or in cooperation with the associated fixed part of said jaw, a U-shaped hook. The U-shaped hooks of the first jaw face, by their inner edges, the U-shaped hooks of the second jaw when the first and second jaws are coupled to the faceplate. As mentioned above, the U-shaped hooks of the first and second jaws face each other by their inner edges. Each hook of a jaw is open towards the longitudinal edge of the faceplate closest to the jaw when the jaws are coupled to the faceplate. Thus, once the legs are inserted into the holes in the faceplate, simply inserting the wheel between the jaws tends to spread the U-shaped hooks of the jaws apart, reinforcing their attachment to the faceplate so that any accidental disassembly of the jaws is prevented. However, disassembling such jaws from the faceplate remains extremely easy.

[0009] According to one embodiment of the invention, at least one of the means of preventing movement of one of the guide shafts in a bearing is a radial screw in said bearing. Again, this arrangement allows for rapid, tool-free installation. It is sufficient to rotate the screw to achieve axial immobilization of the shaft in said bearing through the interaction of the screw tip with the bevel of the shaft, in the direction of shaft insertion into said bearing.

[0010] According to one embodiment of the invention, the moving part of the first jaw, or respectively of the second jaw, is formed by a flange. This results in a simpler installation.

[0011] According to one embodiment of the invention, the fixed part of the first jaw, or respectively of the second jaw, is formed by an L-shaped profile closed at each end by a cheek. This fixed part can thus be simply produced, for example, by bending, cutting, and drilling a sheet of metal.

[0012] According to one embodiment of the invention, a through opening serving as a gripping handle for the fixed part is provided in each cheek. This design allows for easy gripping of the fixed part of the first and second jaws.

[0013] According to one embodiment of the invention, the flange forming the moving part of the first jaw, when coupled to the plate, is provided, on its back face opposite the face facing the moving part of the second jaw, with at least two parallel guide shafts. These guide shafts, configured to insert at one end into a bearing of the fixed part of the first jaw, are preferably beveled along at least part of their length to form a shaft of increasing thickness from their insertion end into the bearing towards their connection point on the back of the moving part of the first jaw. This configuration again allows for quick, tool-free assembly. The bevel on the shafts allows them to be used interchangeably for either jaw.

[0014] According to one embodiment of the invention, the installation includes a platform raising and lowering drive mechanism. Such a platform raising and lowering drive mechanism, of the scissor type or otherwise, relieves the operator, who can then work on the machine at a comfortable working height. Brief description of the drawings

[0015] The invention will be better understood upon reading the following description of exemplary embodiments, with reference to the attached drawings in which: [ Fig. 1 ] represents a perspective view of an installation according to the invention in the positioned state of a device on said platform; [ Fig. 2 ] represents a perspective view of an installation according to the invention; [ Fig. 3 ] represents an exploded perspective view of the constituent elements of a second support device; [ Fig. 4 ] represents a cross-sectional view of the first bit; Fig. 5] represents a cross-sectional view of the second bit.

[0016] As mentioned above, the invention relates to an installation 1 for maintaining a two- or three-wheeled rolling machine 15 in an upright state in preparation for an intervention, such as a change of tire, brake pad or disc or suspension or other on the machine 15.

[0017] Installation 1, as illustrated in Figures 1 And 2 includes a plate 2 which has two ends 31 and 32. This elongated plate 2 extends longitudinally from an end 31 towards the opposite end 32 of said plate.

[0018] This elongated plateau 2 still has two opposite faces 33 and 34, one represented in 33 in the figures, forming the so-called top face, the other, represented in 34 in the figures, forming the bottom face turned towards the ground of said plateau 2.

[0019] This platform 2 is designed to extend horizontally in the configuration of use of the installation 1 when the installation rests on a flat horizontal surface.

[0020] This platform 2 may include a drive mechanism (not shown) for raising and lowering the platform 2, located beneath the platform 2. This drive mechanism for raising and lowering the platform 2 may be a scissor-type drive mechanism. This platform 2 may, as in the example shown, be without such a drive mechanism and rest directly on the ground.

[0021] This second tray is usually made of metal and is quadrangular in shape.

[0022] This platform 2 is equipped at one of its ends, namely here end 31, with a first retaining device 4 having at least two jaws 41 and 42 capable of forming a vise to allow a vise grip of at least one wheel of the machine 15, in this case the front wheel of said machine 15.

[0023] The opposite end 32 of platform 2 can be equipped with an access ramp to said platform 2, as in the example shown.

[0024] The jaws 41 and 42 of the first retaining device 4 can be fixed or movable without going out of the scope of the invention.

[0025] Characteristically to the invention, the installation includes a second retaining device 5. The first and second retaining devices are disposed, one at one end 31, the other at the other end of the face 33 of the top of the tray 2.

[0026] Thus, the first retaining device 4 is located at the end 31 of the tray 2, while the second retaining device 5 is located at the end 32 of the top face of the tray 2.

[0027] The second retaining device 5 is removably mounted on the plate 2. This second retaining device 5 comprises a first jaw 61 and a second jaw 62 which can be positioned opposite each other in a direction transverse to a longitudinal axis of the plate 2 which passes through the first and second ends of the plate 2.

[0028] The first and second jaws each comprise a fixed part which, in the coupled state to the plate 2, is stationary, and a movable part mounted to slide relative to the fixed part, in the direction of a bringing closer or a moving further away from the other jaw, in the state positioned opposite said first and second jaws 61 and 62 with the movable parts arranged between the fixed parts.

[0029] Thus, the first jaw comprises a fixed part shown in Figures 612 and a movable part shown in Figures 611. Similarly, the second jaw 62 comprises a fixed part shown in Figures 622 and a movable part shown in Figures 621.

[0030] The first jaw 61 is a jaw whose movable part 611 can be positioned precisely relative to the fixed part 612 of the first jaw 61. For this purpose, the movable part 611 of the first jaw 61 is connected to the fixed part 612 of the first jaw by a drive device 7 comprising a screw 71 / nut 72 assembly to allow, in the driven state in rotation of the screw 71, an axial displacement of the movable part 611.

[0031] The detail of this first bit 61 is shown in the figure 4 In this embodiment, the fixed part 612 of the first jaw is formed by an L-shaped profile seen in cross-section, this L-shaped profile being closed at each end by a cheek. A through opening 13, functioning as a gripping handle for the fixed part, is provided in each cheek.

[0032] The movable part 611 of the first jaw is formed by a flange. The movable part 611 of the first jaw 61 has, in the coupled state of the jaws to the plate 2, a surface 6111 called front opposite the second jaw 62 and an opposite surface 6112 called back.

[0033] The screw 71 of the device 7 for driving the moving part 612 of the first jaw 61 is fixed to the back of the flange, constituting said moving part 611 of the first jaw, in a freely rotating manner.

[0034] Nut 72 is fixed to the fixed part 612 of the first jaw which rests by one of the arms of the L on the plate 2. The other arm of the L is fitted with this nut through which the screw 71 passes.

[0035] This screw 71 is provided at its free end with a rotating drive element, such as a handwheel equipped with a crankpin. Thus, the rotational drive of the screw 71 generates, due to the fixed rotational mounting of the nut 72, an axial displacement of the screw 71 and, consequently, of the flange constituting the movable part 611 of the first jaw 61 in the direction of a bringing towards or a moving away of the second jaw 62 according to the direction of rotation of the screw 71.

[0036] The flange of this first jaw 61 can be immobilized against rotation, either by contact with the plate 2, or by a means of connection with the fixed part 62 of the first jaw 61. Thus, the moving part 611 of the first jaw 61 is mounted substantially fixed against rotation.

[0037] To assist the sliding movement of the movable part 611 of this first jaw 61 relative to the fixed part 612 of the first jaw 61, the flange forming the movable part 611 of the first jaw 61 is, in the coupled state of the first and second jaws 61 and 62 to the plate 2, provided on its face called back 6112 opposite to that opposite the movable part 622 of the second jaw 62, with at least two parallel guide axes 81.

[0038] These guide axes 81 are configured to insert each by one end into a bearing 6121 of the fixed part 612 of the first jaw 6.

[0039] In the examples shown, these guide axes 81 have a bevel 91 over at least part of their length to form an axis of increasing thickness from their insertion end in the bearing 6121 towards their connection area to the back 6112 of the moving part 611 of the first jaw 61.

[0040] As mentioned above, one of the arms of the L of the fixed part 612 of this first jaw 61 is positioned in support on the plate 2. The other arm of the L is provided with the two through bearings 6121 with axis parallel to the first arm of the L, and which are intended to receive the guide shafts 81 described above.

[0041] The second jaw 62 also includes, as mentioned above, a fixed part 622 which, in the coupled state to the plate 2, is stationary and a movable part 621 mounted movably to slide relative to the fixed part 622 in the direction of a bringing together or moving apart of the first jaw 61 in the coupled state of the first and second jaws 61 and 62 to the plate 2.

[0042] The second bit 62 is shown at the figure 5 . The fixed part 622 of the second jaw 62 is formed by an L-shaped profile closed at each end by a cheek.

[0043] A through opening 13, serving as a gripping handle for the fixed part 622, is provided in each cheek. It should be noted that in the examples shown, the fixed parts are identical from one jaw to another at the level of this L-shaped profile, resulting in a simplified design.

[0044] Again, one of the arms of the L of the fixed part of the second jaw 62 is positioned in support on the plate and the other arm of the L is provided with two through bearings 6221, with an axis parallel to the first arm of the L and whose role will be described below.

[0045] The moving part 621 of the second jaw 62 is formed by a flange. This moving part 621 of the second jaw 62, which, in the coupled state of the jaws to the plate 2, has a surface called front 6211 opposite the first jaw 61 and an opposite surface called back 6212, is equipped with at least two parallel guide axes 82 extending outward from the back 6212 of the moving part 621.

[0046] These guide axes 82 are configured to insert each by one end into a bearing 6221 of the fixed part 622 of the second jaw 62.

[0047] These guide axes 82 are beveled over at least part of their length, to form an axis of increasing thickness from their insertion end in the bearing 6221 towards their connection area to the back 6212 of the moving part 621.

[0048] Each bearing 6221 is equipped with a device 10 for immobilizing the shaft in said bearing 6221 capable of coming into contact with the bevel 92 of said shaft 82.

[0049] This immobilizing element 10 for the movement of one of the guide axes 82 in a bearing 6221 is, in the examples shown, a radial screw of said bearing 6221.

[0050] Each radial screw thus comes, by its free end, to rest on the chamfer of the guide shaft 82 to prevent its axial displacement in the direction of a further insertion into the bearing 6221 corresponding to a displacement of the flange constituting the movable part 621 of the second jaw in the direction of a rapprochement of the fixed part 622 of the second jaw 62.

[0051] To allow the fixed parts 612 of the first jaw 61 and the fixed part 622 of the second jaw 62 to be fixed to the plate 2, said fixed parts 612 and 622 are each equipped with at least two tabs 12, each of which is insertable into a hole 11 in the plate 2, for holding the associated fixed part in a stationary position. The plate 2 is therefore provided with through holes 11.

[0052] The two legs 12 of the first bit 61, shown in the example, form a U-shaped hook in cooperation with the associated fixed part 612 of the first bit 61. Similarly, the legs 12 of the second bit 62 form a U-shaped hook in cooperation with the associated fixed part 622 of the second bit 62. A similar U-shaped hook could have been obtained using only the leg.

[0053] The U-shaped hooks of the first bit 61 face the U-shaped hooks of the second bit 62 in the coupled state of the first and second bits.

[0054] Thus, the hooks of a bit are open towards the longitudinal edge of the plate closest to the bit.

[0055] The U-shaped hooks tend to move apart from each other as they sink deeper into the through holes in the plate when the fixed parts of the first and second jaws are coupled to the plate 2 when the first and second jaws are stressed in the direction of moving apart from each other, in particular when the moving parts of said jaws are stressed in the direction of moving apart from each other, so that any risk of untimely disengagement of said fixed parts of the first and second jaws 61 and 62 of the plate 2 is prevented.

[0056] In practice, the operation of such an installation is as follows: it is assumed that platform 2 is positioned horizontally in height or not, depending on whether a device for raising platform 2 is provided.

[0057] The first retaining device 4 is positioned on the face side 33 of the top of the tray 2 at one end, for example the end 31 of the tray 2.

[0058] The device 15 such as a motorcycle is introduced onto the platform 2 by the opposite end 32 of the platform 2 and is brought to the first retaining device 4, so that the front wheel of the device is held in a vise at the level of the first retaining device 4 between the jaws 41 and 42 of the first retaining device 4.

[0059] The second retaining device 5 can then be put in place at the opposite end 32 of the plate 2. For this purpose, the fixed part 622 of the second jaw 62 is coupled by means of the lugs 12 in the holes 11 of the plate 2, and the movable part 621 of the second jaw 62 is moved by hand by sliding relative to the fixed part 622, until it comes to rest against a side of the rear wheel of the machine 15. In this position, each radial locking member 10 associated with a bearing 6221 of the fixed part 622 is screwed in to bear against a chamfer of one of the guide shafts 82 of the second jaw 62 inserted in said bearing 6221.

[0060] The assembly of the second jaw 62, which extends from one side of the rear wheel, is complete.

[0061] The fixed part 612 of the first jaw 61 of the second retaining device 5 is similarly fixed to the plate 2, like that of the second jaw 62. The moving part 611 of the first jaw 61 is guided in sliding motion by the guide shafts 81, which are mounted to slide freely in the bearings 6121 of the fixed part 612 of the first jaw 61. The screw 71, which is one end, freely coupled in rotation to the moving part 611 of the first jaw 61 and which is screwed into the nut 72 of the fixed part 612 of the first jaw 61, is driven in rotation to allow the moving part 611 of the first jaw 61 to move away from the fixed part 612 of the first jaw 61 until the moving part 611 of the first jaw 61 comes to rest against the side of the rear wheel of the machine 15 opposite to the one against which the moving part of the second jaw rests upon.

[0062] The assembly is then complete, and work on the machine can be carried out. This work can be performed after the front wheel of the machine has been removed from the clamp formed by the first retaining device 4.
