Description

[Technical field]

[0001] This invention relates to a rear stand attachment that detachably mounts a rear stand for fixing the rear wheel of a motorcycle vertically to a support surface in a raised state to the rear swing frame on the left and right sides of the rear wheel. [Background technology]

[0002] When maintaining and servicing motorcycles, various stands are used to keep the vehicle upright. Among these stands, rear stands hold the rear wheel in a vertical position, allowing for efficient inspection and maintenance of the suspension in particular. At the same time, the entire vehicle body can also be held upright, making it easy to inspect even the finer details. Furthermore, because they reduce the load on the tires, they are used not only for maintenance but also for long-term storage.

[0003] A typical rear stand is constructed by connecting a pair of roughly L-shaped side frames with a roughly U-shaped or V-shaped main frame, and the ends of each side frame are rotatably attached to the left and right rear swing arms that connect the left and right sides of the rear wheel of a motorcycle to the body frame. A roller is attached to the bent part of each side frame, and the body can be stood up simply by rotating the rear stand while lifting the rear wheel, using this roller as a fulcrum.

[0004] Normally, rear stands are attached to the rear frame via an attachment, and commercially available rear stands come with a pair of attachments. The most commonly used such attachments are commercially available products called L-type attachments.

[0005] This L-shaped attachment is equipped with a square column-shaped fitting part that is inserted and fitted into a square tube-shaped mounting jig provided at the tip of the left and right side frames that make up the rear stand and then screwed in place with a fixing screw, an L-shaped receiving base that is rotatably connected to the tip of this fitting part, and a belt-like fastener that fixes the receiving base in a state where it is in contact with the lower corner of the rear swing arm (see Patent Document 1). The receiving base is L-shaped, with a vertical plate member that stands vertically and a horizontal plate member that extends horizontally connected at right angles to each other. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Design Registration No. 1746049 Summary of the Invention [Problem to be solved by the invention]

[0007] The fastener of the conventional L-shaped attachment is a rubber belt with many holes punched at equal intervals along its length. The base is formed in an L-shape by connecting a vertical plate member standing vertically and a horizontal plate member extending horizontally in a direction perpendicular to each other, and the front side of the attachment faces the rear stand, with the fitting part connected to the front side of the vertical plate member. A first rivet protrudes from the front of the vertical plate member of the base, and a second rivet protrudes from the underside of the horizontal plate member.

[0008] Therefore, the hole on one end of the rubber belt is hooked onto the first stud, and the rubber belt is wound around the rear swingarm with the support base in contact with the rear swingarm, and when the rubber belt is tightened, the hole at the position of the second stud is hooked onto the second stud to fasten the L-shaped attachment to the rear swingarm. In this way, the rear stand is attached to the left and right rear swingarms at both left and right ends via the left and right L-shaped attachments fastened to the rear swingarms with the rubber belt. In this way, the rear stand is attached to the left and right rear swingarms at both left and right ends via the left and right L-shaped attachments fastened to the rear swingarms with the rubber belt.

[0009] However, when a rubber belt is used as a fastener as described above, if a large load is applied to the L-shaped attachment that is fixed in a fastened state, the rubber belt stretches due to its elasticity, loosening the attachment and making the mounting state of the rear stand unstable. Such a loosened fixed state makes the worker who actually performs maintenance feel uneasy, and the work efficiency decreases. Moreover, repeated use of the rubber belt also puts a load on the punched holes, which may tear and cause the rear stand to come off during work.

[0010] In addition, rubber belts tend to deteriorate relatively quickly over time due to repeated stretching and contraction caused by repeated use, weakening the tightening force and further reducing stability when fastened. Eventually, the belt will exceed its elastic limit and lose its tightening force, which may cause the belt itself to break when a large load is applied.

[0011] The object of the present invention is to provide an attachment for a rear stand that can provide a more stable mounting state of the rear stand than conventional attachments, which is reassuring for the operator and improves workability, while also being less likely to break even with long-term repeated use. [Means for solving the problem]

[0012] In order to achieve the above object, the invention of claim 1 provides a rear stand attachment for removably mounting a rear stand to the left and right rear swing arms of a rear wheel of a motorcycle, An L-shaped support base that supports the rear swing arm by contacting the underside of the target rear swing arm; a rectangular column-shaped fitting portion, one end of which is rotatably connected to the support base, and the other end of which is slidably inserted into a rectangular tube-shaped mounting jig provided at each end of the rear stand, and the mounting jig is removably screwed and fixed at a predetermined position; a fastening belt, the fastening belt having a substantially central portion rotatably sandwiched between the fitting portion and the receiving base, and both end regions of the fastening belt being wrapped around the rear swing arm and engaged with each other to fasten the receiving base to the rear swing arm, The fastening belt is The belt body is a flat belt made of synthetic fiber that does not elastically deform, and an engagement portion that is detachably engaged with both end regions of the belt body in a state where the both end regions are overlapped with each other, The engagement portion is The hook-and-loop fastener is composed of a hook surface member and a loop surface member which can be detachably engaged with each other, and is characterized in having one of the hook surface member and the loop surface member affixed to the outer surface area of ​​one end side of the belt body, and the other of the hook surface member and the loop surface member affixed to the inner surface area of ​​the other end side of the belt body.

[0013] In the rear stand attachment of the present invention having the above-mentioned configuration, the support base is fastened to the rear swing arm by the fastening belt, and the rear stand is attached with the mounting jig at the end screwed to the fitting portion connected to the support base. According to the present invention, the belt body constituting the fastening belt is a flat belt made of synthetic fiber and has high strength that does not elastically deform, so that the fastening state of the rear stand attachment via the support base to the rear swing arm is strong and stable without stretching like a conventional rubber belt, and the stability is maintained even after repeated use over a long period of time. Such a stable fastening state ensures the safety of the worker during work, and high work efficiency can be achieved with peace of mind.

[0014] The flat belt used as the belt body in this invention may be made of synthetic fibers having a certain level of mechanical strength, and may be selected from relatively inexpensive commercially available products. For example, a nylon flat belt is preferred, which is the strongest of all synthetic fibers, has excellent resistance to friction and shock, and is also excellent in heat resistance.

[0015] In addition, in the present invention, the engaging portion that detachably engages both ends of the fastening belt is composed of a hook-and-loop fastener, so that while it is easy to attach and detach, there is no risk of damage such as stretching or tearing, which occurs when hooking through holes in a rubber belt, and a secure and stable engagement state can be obtained. As the hook-and-loop fastener, a fastener with high engagement strength can be selected from those generally available on the market. There are various hook-and-loop fasteners available on the market, and the engagement strength varies accordingly. However, since the direction along the engagement surface is where the load is greater when the receiving base is attached, it is preferable to select a fastener with a particularly high tensile shear strength.

[0016] The receiving base and the mating part do not need to have special specifications different from the conventional ones, so the components can be the same as the conventional ones. This allows existing manufacturing lines and materials to be used, which helps to reduce costs. For example, the mating part can be made of carbon steel, which is relatively inexpensive and has high mechanical strength, just like the conventional ones.

[0017] In addition, since the support base is fastened by a fastening belt while abutting against and supporting the underside of the rear swingarm, it is preferable that the support base is made of reinforced rubber that is less likely to damage the abutting rear swingarm, as in the past. However, if the abutting surface is smooth, there is a risk of slipping and shifting. Therefore, it is preferable that the surface of the support base that abuts against the underside of the rear swingarm is provided with a plurality of anti-slip ridges that are integrally formed in a mutually parallel arrangement along a direction perpendicular to the longitudinal direction of the rear swingarm. Effect of the Invention

[0018] As explained above, according to the rear frame attachment of the present invention, the belt body constituting the fastening belt that fastens the support base to which the fitting portion to which the rear frame is attached is connected to the rear swing arm while supporting it from below is a flat belt made of high-strength synthetic fiber that does not elastically deform, and the engagement portion that detachably engages both ends is made of a hook-and-loop fastener, so that the support base is fixed firmly and stably to the rear swing arm without stretching like a conventional rubber belt, and as a result, the mounting state of the rear stand is more stable than before, and this stability is maintained even after repeated use over a long period of time. In addition, safety is ensured for the operator, and there is no anxiety during the work, resulting in high work efficiency. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] A rear stand attachment according to one embodiment of the present invention will be described below with reference to Figures 1 to 5. As shown in Figures 4 and 5, the rear stand attachment (hereinafter, simply referred to as attachment) 1 according to this embodiment is intended to be mounted on a typical rear stand 100, which is configured by connecting a pair of left and right substantially L-shaped side frames (101A, 101B) with a substantially U-shaped main frame 102, and by attaching rollers (103A, 103B) serving as pivot points to the bent portions of the side frames (101A, 101B).

[0021] In such a rear stand 100, mounting jigs (104A, 104B) are provided at the ends of each side frame (101A, 101B), and the rear stand 100 is attached to the left and right rear swing arms 202 by fixing each mounting jig (104A, 104B) to the left and right rear swing arms 202 with the same configuration of attachments 1 of this embodiment.

[0022] The mounting jigs (104A, 104B) provided at the ends of the side frames (101A, 101B) are made of square tube members 105, and fixing screws 106 are threadedly inserted into the side surfaces of the square tube members 105.

[0023] The attachment 1 in this embodiment comprises an L-shaped plastic support 2 that abuts against the lower corner of the rear swing arm 202 to support the rear swing arm 202 from below, a square column-shaped fitting portion 5 whose tip is connected to the support 2 and is slidably inserted into a square tube member 105 of the mounting jig (104A, 104B) and fixed in a predetermined position by a fixing screw 106, and a fastening belt 10 that fastens the support 2 to the target rear swing arm 202.

[0024] The receiving stand 2 has an L-shaped configuration with a vertical plate member 2a standing vertically and a horizontal plate member 2b extending horizontally connected to each other in the perpendicular direction, and a core rod 3 is integrally provided protruding from the front side (the side facing the rear stand) of the vertical plate member 2a. This core rod 3 is for attaching a fitting portion 5 to the receiving stand 2, and a male thread portion 4 is provided at its tip.

[0025] The fitting portion 5 is composed of a square cylindrical frame member 6 having a square columnar external shape that is loosely fitted onto the core rod 3, and a cap nut 9 that is screwed onto the male threaded portion 4 of the core rod 3 protruding from the other end opening of the frame member 6 via a chamfered washer 7 and a spring washer 8. The frame member 6 is slightly shorter than the core rod 3, and is rotatable between the chamfered washer 7 and the support pedestal 2. This allows the rear stand 100 fixed via the mounting jigs (104A, 104B) to rotate with respect to the rear wheel 201 when standing up or down.

[0026] The belt body 11 is attached between the frame member 6 and the receiving base 2 with the core rod 3 inserted through a through hole H formed in the approximate center of the belt body 11 and grommeted. Therefore, the fastening belt 10 is attached in a rotatable state through the through hole H, which makes it easy to handle when winding the fastening belt 10 around the rear swing arm 202.

[0027] Moreover, the fastening belt 10 is configured with a belt body 11 made of a nylon flat belt and a hook-and-loop fastener 12 as an engagement portion. The hook-and-loop fastener 12 is configured with a loop surface member (or hook surface member) 12a attached to the outer surface region of one of both end portions of the belt body 11, and a hook surface member (or loop surface member) 12b attached to the inner surface region of the other of both end portions of the belt body 11, which are detachably engaged with each other.

[0028] Therefore, with the receiving base 2 in contact with the lower corner of the rear swing arm 202 to be attached, both ends of the belt body 11 are wound around the rear swing arm 202 and the loop surface member (or hook surface member) 12a and the hook surface member (or loop surface member) 12b are overlapped and engaged with each other, thereby firmly binding the receiving base 2 to the rear swing arm 202. As a result, each attachment 1 fixed to the mounting jigs (104A, 104B) at the ends of the left and right side frames via the fitting parts 5 connected to each receiving base 2 attaches the rear stand 100 to the left and right rear sling arms.

[0029] In this embodiment, a plurality of anti-slip ridges S are provided on the upper surface of the horizontal plate member 2b of the support stand 2, which comes into contact with the underside of the rear swing arm 202, and are integrally formed in parallel arrangement along a direction perpendicular to the longitudinal direction of the rear swing arm 202. Friction caused by these anti-slip ridges S prevents the support stand 2 from slipping against the underside of the rear swing arm 202, making the fixed state of the support stand 2 to the rear swing arm 202, i.e., the mounting state of the rear stand 100, more reliably and stably.

[0030] The procedure for mounting the attachment 1 according to this embodiment having the above configuration to the left and right rear sling arms of the rear stand 100 is as follows: First, as shown in Fig. 4, the same attachment 1 is fixed to the mounting jigs (104A, 104B) at the ends of the left and right side frames (101A, 101B) of the rear stand 100, respectively.

[0031] That is, the fitting portion 5 of each attachment 1 is inserted into the square tube member 105 of each mounting jig (104A, 104B), positioned, and then the fitting portion 5 is simply fixed to the square tube member 105 with the fixing screws 106. Here, the fixing position of each fitting portion 5 relative to the square tube member 105 is adjusted to a position equivalent to the distance between the mounting positions of the left and right rear swing arms 202. This position adjustment can be easily performed because the fitting portion 5 is slidable relative to the square tube member 105.

[0032] After each attachment 1 is fixed to the end of the left and right side frames (101A, 101B) of the rear stand 100 by the above procedure, each attachment 1 is mounted to the left and right rear swing arms 202. That is, with the receiving base 2 of each attachment 1 in contact with the underside of the corresponding rear sling arm, the fastening belt 10 is wound around the rear sling arm, and both ends are overlapped and engaged with the hook-and-loop fastener 12, as shown in Fig. 5, and the mounting of the rear stand 100 to the motorcycle 200 is easily completed.

[0033] In this mounted state of the rear stand 100, even if a large load is applied to the fastening belt 10 every time the rear wheel 201 of the motorcycle 200 is stood up, the fastening belt 10 does not deform and always maintains its strong engagement state. Thus, even when used repeatedly over a long period of time, the mounted state of the rear stand 100 is always good. [Explanation of symbols]
