Bicycle parking stand

Abstract

To provide a bicycle parking stand which can stably park a bicycle that has no self-supporting stand which can be easily assembled, disassembled, stored, carried, and managed for maintenance.SOLUTION: A bicycle parking stand 10 includes: a bar-shape supporting portion 20 that supports a bicycle; and leg portions 30 placed at the right and left ends of the bar-shape supporting portion 20, respectively. The leg portions 30 are composed of two respective bar-shape members 31. By connecting respective upper portions of both members via a pivot, the upper portion can be opened and closed between a V-shape and an I-shape, and the lower portion can be opened and closed between a reversed V-shape and the I-shape. A recess to be engaged with the support portion is provided at the upper portion of the leg portion 30. When the bicycle is parked, as load is applied to the lower surface of the recess, a support bar 21 is engaged with the upper portion of the leg portion 30, and the lower portion is prevented from being opened excessively. Moreover, a bottom end portion 35 of the bar-shape member 31 is cut out in such a way that the entire surface of a ground contact face contacts the ground, and thus friction force between the ground contact face and the ground is enhanced, and the load of the bicycle is supported in a plane-by-plane manner. Hence, the bicycle parking stand 10 is prevented from swinging and falling down laterally.SELECTED DRAWING: Figure 2

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

[0004] However, because the bicycle stand-type hanger described above is intended to hold heavy bicycles, some distortion may occur depending on the load, and as shown in Fig. 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 composed of multiple screws, etc., which may cause problems at the joints. Therefore, if even the slightest distortion occurs in the support or legs, or if damage is found at the joints, the support and legs may not be able to fold properly, or maintenance such as repairs and maintenance may be difficult, which may mean that the entire product must be purchased again.

[0005] Therefore, the object of the present invention is to provide a bicycle parking stand that allows stable parking of bicycles that do not have a free-standing stand, 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-mentioned 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 of a bicycle, and legs arranged on the left and right ends of the rod-shaped support part, the legs being composed of two rod-shaped members, the upper parts of the legs being connected via a pivot so that 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, and the upper parts of the legs having a recess for fitting into the support part.

[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. Effect of the Invention

[0008] The invention described in claim 1 is as described above, and the invention described in claim 1 includes a rod-shaped support part that can hook and support the saddle of a bicycle, and legs arranged on the left and right of the rod-shaped support part, so that the saddle of a bicycle that does not have a self-supporting stand, such as a road bike, can be hooked onto the rod-shaped support part to park the bicycle without laying it down. In addition, the two rod-shaped members that make up the legs can open the upper part of the legs on which the rod-shaped support part is placed into a V-shape around a pivot, and the lower part of the legs that contact the ground can open into an inverted V-shape or return to an I-shape. The invention is characterized by having a recess for fixing the rod-shaped support part above the legs, and can be easily assembled without using tools when in use, and can be stored and transported compactly by separating the rod-shaped support part and the legs when not in use, so that it is not only convenient for consumers but also easy to distribute. In addition, the rod-shaped support part is fitted into the leg without using metal fittings or ropes, but by placing it inside a recess provided in the leg, so malfunctions due to damage or loss of parts are less likely to occur, and even if a malfunction does occur, because 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, thereby generating friction between the cutout surfaces and the ground, preventing wobbling or tipping over during use and making the product 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 is configured with a rod-shaped support part 20, left and right legs 30 composed of two rod-shaped members, and a pivot fitting 32 connecting the legs 30, as shown in Figs. 1 and 2. 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 the other leg is located near the right end, but this is not limited to the above, and it is also possible to arrange another leg near the center of the rod-shaped support part 20 depending on the length of the rod-shaped support part 20 to increase stability during use.

[0013] The rod-shaped support part 20 is a metal rod-shaped member that can support a bicycle saddle by hanging it on it, and this support rod 21 is intended to be used with a single pipe. Single pipes are widely used as scaffolding at construction sites and the like, and because of their usage, they are strong against loads. Furthermore, because they are standardized nationwide, they are easy to obtain and inexpensive. They are available in lengths ranging from 1.0 m to 6.0 m in 50 cm increments, so that the length can be selected according to the number of bicycles to be parked, and if the rod-shaped support part 20 is defective, it can be easily replaced. In addition, if a single pipe is already present at the location where the bicycle is to be used, the rod-shaped support part 20 and the leg part 30 are configured separately, so that the bicycle parking stand 10 can function by carrying only the leg part 30 and using the single pipe at that location. Furthermore, to make it easier to carry, as shown in Figure 7, it is possible to use an expandable 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 insertable 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 the present invention is not limited to the use of a single pipe.

[0014] The legs 30 are disposed at the left and right ends of the rod-shaped support part 20, and serve to horizontally support the rod-shaped support part 20 when in use, as shown in Fig. 1. 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 part of the legs 30 can be opened in a V-shape when in use, and the lower part of the legs 30 that contact the ground can be opened in an inverted V-shape, and as shown in Fig. 3, the legs 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 rod-shaped support part 20 is configured to fit into the legs 30 by placing the support rod 21 inside the recess when in use.

[0015] As shown in Figs. 3, 4, 5, 6, and 11, the leg 30 is two rod-shaped members 31 of the same length and width, and is assumed to be a square prism made of wood that is widely used in building materials (however, the shape, length, and width of the rod-shaped members 31 that constitute the leg 30 are not limited to this in order to fulfill the function of the present invention). As with the use of single-tube pipes as the support rods 21, square prisms made of wood that are used in building materials not only have a certain degree of strength and are easy to obtain, but also allow for the effective use of scraps generated at construction sites. Although wood is cited as a more preferable example from the standpoint of achieving the SDGs and reducing costs, it is also possible to use lightweight metals such as steel and aluminum for ease of portability and weight reduction.

[0016] In order to make the two rod-shaped members 31 that make up the leg 30 function as the 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 fixed at a certain width from the top surface and at the center of the left and right width by passing a pivot fitting 32 such as a bolt through and fixing it, and opening the upper part of the leg 30 in a V shape with the pivot fitting 32 as a fulcrum, and opening the lower part of the leg 30 that comes into contact with the ground in an inverted V shape.

[0017] In order to fix the support bar 21 to the leg 30, for example, as shown in Figs. 4 and 5 when not in use and in Fig. 8 when in use, a U-shaped recess 33 is provided around a point 34 where two rod-shaped members 31 constituting the leg 30 intersect when the upper part of the leg 30 is opened in a V-shape, and at a position facing each other. By arranging the recesses facing each other in such a place, when the saddle part of the bicycle is hung on the support bar 21 and parked, a load is applied to the lower surface 33a of the recess through the support bar 21. The force acting on the lower surface 33a of the recess becomes a force that lifts the upper end 31a of the rod-shaped member 31 upward due to the principle of leverage, that is, a force that sandwiches the support bar 21 between the pair of rod-shaped members 31. Therefore, when the support bar 21 is fitted, the angle of the inverted V-shape of the lower part of the leg 30, which is the diagonal, is fixed, and the lower part of the leg 30 is prevented from opening more than necessary. 8 and 10, the width of the recess 33 is made to be equal to the diameter of the support rod 21, and the depth is made to be slightly larger than the radius of the support rod 21, so that the support rod 21 fits snugly inside the recess 33 during use, and the position of the support rod 21 can be kept more stable. By matching the size and the position of the recess 33 to the size and the installation height of the support rod 21, the support rod 21 can be fitted into the leg 30 without using metal fittings or ropes, and assembly and disassembly can be performed easily and quickly. The shape of the recess 33 is shown as a U-shape in the drawings, but 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 lower surface of the recess when the support rod 21 is inserted.

[0018] The two rod-shaped members 31 of the legs 30 may be cut out at the bottom end 35 at the angle at which the rod-shaped members 31 are to be inclined in order to open the legs 30 when used as the bicycle parking stand 10, so that the entire bottom surface of the rod-shaped members 31 is in contact with the ground when used. This is because, for example, as shown in Fig. 10, if the two rod-shaped members 31 of the legs 30 are square prisms, only the inner side 36 of the bottom surface will be in contact with the ground, which will weaken the frictional force with the ground and concentrate the load on one side, causing the bicycle parking stand 10 to wobble or tip over. By having the entire contact surface in contact with the ground, the frictional force is increased and the load can be supported by the surface, preventing wobbling and tip over when in use and allowing for safer use.

[0019] Since the rod-shaped members 31 of the legs 30 can be folded into an I-shape when not in use, all components, including the support rod 21, can be made rod-shaped for transport or storage. As shown in Fig. 11, if a square wooden column, which is widely used as a building material and is mainly intended for 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 transport and storage. Furthermore, by using an extendable support rod 24 for the rod-shaped support 20, it is possible to align the heights of the legs 30 and rod-shaped support 20 when not in use, making it easier to distribute and sell the bicycle parking stand 10 as a set.
