Bicycle parking stand

Abstract

To provide a bicycle parking stand that enables stable parking of a bicycle without a freestanding stand and is easy to assemble, disassemble, store, transport and maintain. [Solution] The bicycle parking stand comprises a rod-shaped support part that supports a bicycle and legs 30 located on the left and right ends of the rod-shaped support part. Legs 30 are made of two rod-shaped members 31, and by connecting the tops of both via a pivot, they can be opened and closed from an I-shape to a V-shape at the top and an inverted V-shape at the bottom. A recess 33 is provided at the top of legs 30 for fitting the support part. When a bicycle is parked, a load is applied to the underside of recess 33, fitting support rod 21 into the top of legs 30 and preventing the bottom from opening more than necessary. Furthermore, by notching the bottom end 35 of rod-shaped member 31 so that the entire contact surface is in contact with the ground, friction between the contact surface and the ground is increased, the bicycle weight is supported across the entire surface, and the bicycle parking stand does not wobble or tip over.

[Technical Field]

[0001] This invention relates to a bicycle parking stand that can stably park bicycles that do not have freestanding stands, such as road bikes, and that can be stored and transported compactly, can be easily assembled and disassembled, is durable, and is easy to maintain. [Background technology]

[0002] Patent Document 1, a prior art document, discloses a bicycle stand-type hanger that can be used to park bicycles that do not have freestanding stands and that can be folded up for easy portability. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3214516 Summary of the Invention [Problem to be solved by the invention]

[0004] However, because bicycle stand-type hangers like those described above are used to support heavy bicycles, they can become slightly distorted depending on the load, and as shown in Figure 4 of Patent Document 1 (Utility Model Registration No. 3214516), the metal fittings 30 that secure the support rod 11 and the legs 20 are made up of multiple screws, which can cause problems at the joints. Therefore, even the slightest distortion in the support or legs, or damage to the joints, can prevent the support and legs from folding properly, or can make repairs and maintenance difficult, resulting in the need to purchase the entire product again.

[0005] Therefore, the objective of this invention is to provide a bicycle parking stand that can stably park bicycles that do not have freestanding stands, such as road bikes, and that can be easily assembled and disassembled, can be stored and transported compactly, is durable, and is easy to maintain. [Means for solving the problem]

[0006] The present invention has been made to solve the above problems and has the following features. The invention described in claim 1 comprises a rod-shaped support part that can be hooked onto and supported by the saddle part of a bicycle; The device is characterized in that it has legs arranged at the left and right ends of the rod-shaped support part, the legs being composed of two rod-shaped members, the upper parts of both legs being connected via a pivot, and the legs can be opened and closed from an I-shape to a V-shape at the upper part and an inverted V-shape at the lower part around the pivot, the upper parts of the V-shaped legs having recesses for fitting the rod-shaped support part, the recesses being arranged facing each other, and the V-shaped legs have the function of clamping the rod-shaped support part by applying the load of the rod-shaped support part to the underside of the recesses.

[0007] The invention described in claim 2 is characterized in that, in addition to the features of the invention described in claim 1, the two rod-shaped members of the legs are notched so that the entire contact surface is in contact with the ground. [Effects of the Invention]

[0008] The invention of claim 1 is as described above. The invention of claim 1 includes a rod-shaped support part that can hook onto the bicycle's saddle for support, and legs arranged on the left and right of the rod-shaped support part. By hooking the saddle of a bicycle without a self-standing stand, such as a road bike, onto the rod-shaped support part, the bicycle can be parked without lying down. The two rod-shaped members that make up the legs have an upper part that supports the rod-shaped support part and can open into a V-shape around a pivot, while the lower part of the leg that contacts the ground can open into an inverted V-shape, or conversely, return to an I-shape. The legs also have opposing recesses above them for securing the rod-shaped support part. The rack can be easily assembled without tools when in use, and when not in use, the rod-shaped support part and legs can be separated, and the entire rack can be made rod-shaped for compact storage and transportation, making it not only convenient for consumers but also easy to distribute. Furthermore, the rod-shaped support part is fitted to the leg part by placing it inside a recess provided in the leg part without using metal fittings or ropes, so malfunctions due to damage or loss of parts are unlikely to occur, and even if a malfunction does occur, since the rod-shaped support part and each of the legs are independent, only the defective component can be replaced.

[0009] The invention described in claim 2 is as described above, and the two rod-shaped members of the legs are notched so that the entire contact surface is in contact with the ground, creating friction between the notched surface and the ground, preventing wobbling and tipping during use and making it safer to use.

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

[0012] The bicycle parking stand 10 according to this embodiment is for parking bicycles that do not have a freestanding stand, such as road bikes, and as shown in FIGS. 1 and 2, it is configured with a rod-shaped support part 20, left and right legs 30 each composed of two rod-shaped members, and a pivot fitting 32 connecting the legs 30. The rod-shaped support part 20 and the left and right legs 30 are configured separately, and as shown in FIGS. 2 and 3, the legs 30 can be opened and closed around the pivot fitting 32. It is desirable to arrange the legs 30 so that one leg is located near the left end of the support part 20 and one leg is located near the right end, but this is not a limitation; depending on the length of the rod-shaped support part 20, it is also possible to arrange another leg near the center of the rod-shaped support part 20 to increase stability during use.

[0013] The rod-shaped support portion 20 is a metal rod-shaped member onto which a bicycle saddle can be hooked for support, and this support rod 21 is intended to be made of a single-tube pipe. Single-tube pipes are widely used as scaffolding at construction sites and other locations. Given their usage, they are strong enough to withstand loads. Furthermore, because they are standardized nationwide, they are readily available and inexpensive. They are commercially available in lengths ranging from approximately 1.0 m to 6.0 m in 50-cm increments, allowing users to select the length based on the number of bicycles to be parked, and to easily replace the rod-shaped support portion 20 if it malfunctions. Furthermore, if a single-tube pipe is already available at the location where the bicycle will be used, the rod-shaped support portion 20 and leg portion 30 are constructed separately. Therefore, the bicycle parking stand 10 can be functioned by simply transporting the leg portion 30 and using the existing single-tube pipe. To make it easier to carry, as shown in Figure 7, it is possible to use an extendable support rod 24 consisting of a slidable outer rod 22 and inner rod 23, with the outer rod 22 at both ends and the inner rod 23 in the center, and the inner rod 23 being able to be inserted into the outer rod 22, or to use a rod-shaped object of the same size as a single pipe and made of a material such as reinforced plastic that can withstand the weight of a bicycle, and the function of this device is not limited to the use of a single pipe.

[0014] The legs 30 are disposed on the left and right ends of the rod-shaped support part 20, and as shown in Fig. 1, serve to support the rod-shaped support part 20 horizontally during use. As shown in Fig. 2, the legs 30 are composed of two rod-shaped members 31, and are fixed by pivot fittings 32 or the like, so that the upper parts of the legs 30 can be opened in a V-shape during use, and the lower parts of the legs 30 that come into contact with the ground can be opened in an inverted V-shape, and as shown in Fig. 3, can be closed in an I-shape when not in use. Furthermore, a recess 33 for placing the support rod 21 is provided at the upper part of the legs 30, above the pivot fittings 32, and the support rod 21 is positioned inside the recess during use, allowing the rod-shaped support part 20 to fit into the legs 30.

[0015] As shown in Figures 3, 4, 5, 6, and 11, the legs 30 are two rod-shaped members 31 of the same length and width, and are primarily intended to be square prisms made of wood, a material commonly used in building materials (however, the shape, length, and width of the rod-shaped members 31 making up the legs 30 are not limited to these when fulfilling the functions of the present invention). Similar to using a single-tube pipe as the support rod 21, square prisms made of wood, which are used in building materials, not only have a certain degree of strength and are easily available, but also allow for the effective use of scrap wood generated at construction sites. While wood is cited as a preferred example from the perspective of achieving the SDGs and reducing costs, it is also possible to use lightweight metals such as steel or aluminum for portability and light weight.

[0016] In order to make the two rod-shaped members 31 that make up this leg 30 function as leg 30, for example, as shown in Figure 2, one of the sides of the two rod-shaped members 31 is aligned top, bottom, left, and right, and a pivot fitting 32 such as a bolt is passed through and fixed at a position a certain width from the top and in the center of the left and right width, and the upper part of leg 30 is opened in a V shape with pivot fitting 32 as a fulcrum, and the lower part of leg 30 that comes into contact with the ground is opened in an inverted V shape.

[0017] To secure the support rod 21 to the leg 30, for example, as shown in Figures 4 and 5 when not in use and in Figure 8 when in use, U-shaped recesses 33 can be provided around the point 34 where the two rod-shaped members 31 constituting the leg 30 intersect when the upper part of the leg 30 is opened in a V-shape, at positions facing each other. By arranging the recesses facing each other in this manner, when a bicycle is parked with the saddle of the bicycle hooked onto the support rod 21, a load is applied to the lower surface 33a of the recess through the support rod 21. The force acting on the lower surface 33a of the recess closes the upper end 31a of the V-shaped opened rod members 31 due to the principle of leverage, i.e., the pair of rod-shaped members 31 clamp the support rod 21. Therefore, when the support rod 21 is fitted, the angle of the inverted V-shape at the diagonal lower part of the leg 30 is fixed, preventing the lower part of the leg 30 from opening more than necessary. 8 and 10, by making the width of the recess 33 equal to the diameter of the support rod 21 and the depth slightly larger than the radius of the support rod 21, the support rod 21 fits snugly inside the recess 33 during use, and the position of the support rod 21 can be maintained more stably. By matching the size and location of the recess 33 to the size and installation height of the support rod 21, the support rod 21 can be fitted into the leg 30 without using metal fittings or ropes, making assembly and disassembly easy and quick. Although the shape of the recess 33 is shown as a U-shape in the drawings, it does not necessarily have to be U-shaped as long as the support rod 21 fits inside the recess 33 and a load is applied to the underside of the recess when the support rod 21 is inserted.

[0018] The two rod-shaped members 31 of the legs 30 should have a notch at the bottom end 35 of each rod-shaped member 31 at the angle at which the legs 30 are tilted to open when in use as a bicycle parking stand 10, so that the entire bottom surface is in contact with the ground when in use. This is because, for example, if the two rod-shaped members 31 of the legs 30 were square prisms, as shown in Figure 10, only the inner side 36 of the bottom surface would be in contact with the ground, which would weaken the friction with the ground and concentrate the load on one side, causing the bicycle parking stand 10 to wobble or tip over. Having the entire contact surface in contact with the ground increases the friction and allows the load to be supported across the entire surface, preventing wobbling and tip over when in use and making it safer to use.

[0019] When not in use, the rod-shaped members 31 of the legs 30 can be folded into an I-shape, allowing all components, including the support rod 21, to be folded into a rod shape for transportation or storage. As shown in Figure 11, if a square wooden pillar, which is widely used as a building material and is the primary intended use, is used for the rod-shaped members 31, two legs 30 can be placed side by side to form a square, thereby saving space during transportation and storage. Furthermore, by using an extendable support rod 24 for the rod-shaped support member 20, it is possible to align the height of the legs 30 and rod-shaped support member 20 when not in use, making it easier to distribute and sell a set of bicycle parking stands 10.
