Description

[0001] TOOL FOR LIFTING OR LOWERING WHEELS

[0002] DESCRIPTION

[0003] OBJECT OF THE INVENTION

[0004] The object of the present invention, as stated in the title of the invention, is a tool for lifting or lowering wheels in the assembly or disassembly process, so that it does not require holding the wheels by hand during either of the two actions.

[0005] The present invention is characterized by the special design and configuration of each and every one of the pieces and elements that make up the tool, so that a tool that is simple in conception and manufacture and effective in its results is achieved.

[0006] Therefore, the present invention is circumscribed within the field of tools and accessories used in the mechanics, preferably of motorcycles.

[0007] BACKGROUND OF THE INVENTION

[0008] In the state of the art, lifting or lowering stands are known, used to work with motorcycles and similar items, allowing the motorcycle to be lifted, leaving one of the wheels in the air, which facilitates both repairs and the mounting and dismounting of wheels.

[0009] However, although these wheel assembly and disassembly operations are facilitated by lifting stands, they do not solve the problem of raising and lowering the wheels for assembly or disassembly, since these actions have to be done manually, with the consequent difficulties, such as the possibility of injury, falling from some force as well as the effort that would have to be made when having to lift and hold the wheels by hand in the lifting and lowering processes.

[0010] Therefore, the object of the present invention is to improve the assembly and disassembly processes of the wheels from how they have been carried out until now so that it becomes necessary to lift or lower the wheels by hand during assembly and disassembly, developing an auxiliary tool as described below and included in its essential aspects in claim one.

[0011] DESCRIPTION OF THE INVENTION

[0012] The object of the present invention is set out in its essentials in the independent claim and the different embodiments are set out in the dependent claims.

[0013] The present invention relates to a tool for raising or lowering wheels during the wheel assembly or disassembly process in such a way that human effort is not required, freeing the hands to carry out complementary actions such as the fixing or loosening of the nuts of the fixing screws to the fixing plate.

[0014] To achieve this purpose, the tool has a support or base for ground support and a piece or support that can be lifted relative to the support support, the lifting support being housed in the interior space defined by the support support, the support support and the lifting support being joined together, and also having manual means of operation such that when activated it allows the lifting of the lifting support relative to the support support.

[0015] The connection between the support bracket and the lifting bracket can be made either by means of a hinged joint using a pivot axis, or by means of pairs of connecting rods arranged on both sides of the lifting bracket, such that pushing the lifting bracket raises it relative to the support bracket. The support bracket has a base, preferably rectangular, and a vertical wall at one end of the base. This vertical wall and the base are joined by lateral reinforcing brackets.

[0016] On the other hand, the liftable support has a movable support base, preferably rectangular, an interior vertical wall joined at the ends of the movable support base, with both elements being joined by means of interior brackets.

[0017] The drive means that allow the lifting of the liftable support with respect to the support support in one possible embodiment consist of a drive comprising a threaded screw rotatable by means of a handle or grip, wherein said threaded screw passes through a threaded hole made in the vertical wall of the support support, either because said hole is threaded on the inside or because a nut has been welded to it.

[0018] When the lifting support is operated by the drive means, the lifting support is raised relative to the support support.

[0019] When the lifting support is joined to the support support by means of an articulating joint and the drive means are acted upon, the lifting support tilts with respect to the support support by tilting or rotating the lifting support with respect to the support support by means of a pivot axis arranged in the articulating joint.

[0020] When the lifting support is connected to the support bracket by two pairs of connecting rods, articulated at one end to the lifting support and at the other to the support bracket, applying pressure to the tilting support causes the lifting support to rise relative to the support bracket, maintaining a uniform distance along its entire length. Thanks to these characteristics, a tool is created that can be used as an auxiliary tool for a motorcycle lifting stand, allowing the wheel to be raised or lowered without any effort, freeing the hands for better manipulation of the other components involved in lifting or securing the wheel.

[0021] Unless otherwise stated, all technical and scientific terms used herein have the meanings commonly understood by a person skilled in the art to which this invention pertains. Similar or equivalent procedures and materials to those described herein may be used in the practice of this invention.

[0022] Throughout the description and claims, the word "comprises" and its variations are not intended to exclude other technical features, additives, components, or steps. For those skilled in the art, other objects, advantages, and features of the invention will become apparent partly from the description and partly from the practice of the invention.

[0030] PREFERRED EMBODIMENT OF THE INVENTION

[0031] In view of the figures, a preferred embodiment of the proposed invention is described below.

[0032] In Figure 1 we can observe the tool that is the object of the invention, where said tool is supporting a wheel (16) with a motorcycle being lifted by means of a stand (17).

[0033] The tool comprises a support stand (1) and a liftable stand (2), where the liftable stand (2) is housed in the interior space defined by said support stand (1) and can be raised or tilted with respect to the support stand (1) depending on the type of connection it has with respect to the support stand, also having as manual drive means such that when actuated it allows the lifting of the tiltable stand (2) with respect to the support stand (1).

[0034] Figure 3 shows in detail the support bracket (1), which, as can be seen, comprises a support base (3) and a vertical wall (4) located at one end of the support base (3). Both elements are joined by external reinforcing brackets (5). Furthermore, a hole (12) is defined in the vertical wall (4), which in the embodiment shown is threaded by means of an internally threaded nut (13). Figure 5 shows the use of an externally threaded nut (20) welded to the outer face of the vertical wall (4) to retain the threaded rod (11) in the hole (12). Additionally, opposite holes (18), preferably threaded, are arranged on the upper ends of the reinforcing brackets (5) for the passage of a shaft (14).

[0035] On the other hand, Figure 4 shows in detail the lifting support (2), which, as can be seen, comprises a movable support base (6) that has an inner vertical wall (7) at one end. The movable support base (6) is joined to the vertical wall (7) by means of internal reinforcing brackets (8). In addition, at least a pair of holes (19), preferably threaded, are arranged opposite each other on the upper ends of the reinforcing brackets (8) for the passage of a shaft (14).

[0036] A first way of carrying out the union of the support support (1) and the lifting support (2) is by means of an articulated joint which, as can be seen in figure 1, comprises a pivot axis (14) that passes through the outer reinforcing brackets (5) and the inner reinforcing brackets (8) being fixed at its ends by means of fasteners (15).

[0037] The drive means employed, as shown in both Figure 1 and Figure 5, comprise a threaded rod (11) that passes through the vertical wall (4) via a perforation (12) and contacts the inner vertical wall (7) at its end. The threaded rod (11) has an actuating handle (10) at its free end, such that turning it advances the threaded rod (11), pushing the inner vertical wall (7) and tilting the pivoting support (2) about the axis of rotation (14), thereby raising the movable support base (6).

[0038] To retain the threaded stem (11) in position, the bore (12) must either be threaded or have an internally threaded nut (13) welded to it on the vertical wall (4). Alternatively, or in addition to the internally threaded nut (13), an externally welded nut (14) can be used to increase the threaded contact surface between the threaded stem (11) and the threaded bore (12), thus increasing the retention of the threaded stem.

[0039] Figures 6 and 7 show a second embodiment of the connection between the support bracket (1) and the lifting bracket (2) consisting of the arrangement of a first pair of connecting rods (21) placed at the front of the tool and a second pair of connecting rods (22) placed at the rear of the tool.

[0040] Each pair of connecting rods is arranged facing each other, with the first pair of connecting rods (21) being articulated at a first end (21.1) with the support bracket (1), while a second end (21.2) of said pair of connecting rods (21) is articulated with the lifting bracket (2).

[0041] On the other hand, the second pair of connecting rods (22) placed at the back of the tool, is joined at a first end (22.1) with the support bracket (1), while the second end (22.2) is joined with the lifting bracket (2).

[0042] Having sufficiently described the nature of the present invention, as well as the manner of putting it into practice, it is stated that, within its essential nature, it may be put into practice in other forms of embodiment that differ in detail from the one indicated as an example, and which will also achieve the protection sought, provided that it does not alter, change or modify its fundamental principle.
