Description

[Technical Field]

[0001] The present invention relates to a bicycle parking device in which the rack for placing bicycles can slide or rotate horizontally, and in particular to a bicycle parking device equipped with a mechanism for preventing the rack from sliding or rotating when a bicycle is placed on it. [Background technology]

[0002] Conventionally, bicycle parking lots located in front of train stations or commercial facilities have widely used bicycle parking devices that allow bicycle racks to slide or rotate horizontally in order to reduce the distance between bicycles or to prevent bicycles from bumping into each other when parked (see Patent Document 1 and Patent Document 2).

[0003] For example, Patent Document 1 discloses an example of a bicycle parking device equipped with two upper and lower racks for placing bicycles, in which the lower rack can be rotated around an axis at its front end so that bicycles on the lower rack do not get in the way when the upper rack is tilted to load or unload bicycles. The bicycle parking device in Patent Document 1 is provided with guide rollers that guide the lower rack when the rear end of the rack is rotated left and right.

[0004] Furthermore, Patent Document 2 discloses a locking mechanism for a sliding bicycle parking device in which the rack slides sideways along a slide rail, preventing the rack from sliding sideways when bicycles are loaded or removed. The locking mechanism in Patent Document 2 is configured so that a rod-shaped stopper fitting with a rubber stopper at the bottom end is attached to the end of the bicycle loading / unloading opening, and this is moved towards or away from the ground in conjunction with loading or unloading a bicycle, thereby locking the rack to prevent sliding sideways and turning it on and off.

[0005] [Patent Document 1] JP 8-042178 [Patent Document 2] Patent Publication No. 2006-347362 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the locking mechanism in Patent Document 2 uses two elastic members: a coil spring that lifts the stopper fitting and a coil spring that presses the stopper fitting against the ground, which results in a complex structure and high manufacturing costs.

[0007] The present invention has been made in view of the above-mentioned problems, and aims to provide a bicycle parking device that has a simple structure and can prevent the bicycle parking device from unexpectedly skidding or rotating. [Means for solving the problem]

[0008] The invention made to solve the above problem is a bicycle parking device comprising a rack with a groove-shaped opening at its rear end and a stopper device that prevents the rack from sliding or rotating, wherein the stopper device has a stopper pedal made of a plate-shaped or rod-shaped elastic member, the stopper pedal including an arm portion attached to the front end and a leg portion attached to the rear end, the front end of the arm portion being fixed to the bottom of the rack and extending rearward, the rear end of the leg portion being extended downward, and the rear end of the leg being configured to directly or indirectly come into contact with the ground when the bicycle wheel rides over the stopper pedal.

[0009] In this way, the bicycle parking device of the present invention has an arm that extends rearward from the opening and a leg that extends downward from the rear end of the stopper pedal, so the bicycle wheel can be lifted up along the slope of the leg and guided into the rack along the arm.The stopper pedal is made of an elastic member, and is arranged so that the rear end of the leg comes into contact with the ground when the bicycle wheel rides over the stopper pedal, so that the friction prevents the rear end of the rack from sliding or rotating.

[0010] While the wheel is on this stopper pedal, the stopper pedal is restrained by the wheel, and part of the elastic force that tries to lift the wheel as the stopper pedal returns to its original position acts as a reaction force in a direction pressing the rear end of the leg of the stopper pedal against the ground. Then, when the wheel passes the stopper pedal, the elastic force of the stopper pedal acts in a direction returning the stopper pedal to its original state before deformation. In this way, by forming the stopper pedal from an elastic material, the elastic force of the stopper pedal can be made to perform both the function of pressing against the ground and the function of returning the stopper pedal to its original position.

[0011] The arm preferably has an inclined portion that becomes higher toward the rear. This prevents the wheels housed in the rack from rolling backward over the arm. Note that "higher" here means that the height from the ground is higher.

[0012] The legs preferably have folded portions at their lower ends, which deform in a direction that reduces the folding angle θ (see Figure 2) when they come into contact with the ground, and the elastic force generated at this time presses against the ground, thereby increasing the friction between the legs and the ground.

[0013] The bicycle parking device of the present invention preferably has a wall surface erected at the front, the rack is provided so that the rear end side rotates horizontally around a rotation shaft supported on the wall surface, and the rotation of the rack around the rotation shaft is stopped when the front end of the rack abuts against the wall surface. This makes it possible to limit the range of unexpected rotation of the rack when the arm is not working.

[0014] The bicycle parking device of the present invention has a wall surface erected at the front, the rack is configured so that the rear end side thereof rotates horizontally on a rotation shaft supported on the wall surface, the pivotal support portion includes a rack-side pivotal member fixed to the front end of the rack, a wall-side pivotal member fixed to the wall surface, and a vertical rotation shaft connecting the wall-side pivotal member and the rack-side pivotal member so that the rack-side pivotal member rotates horizontally relative to the wall-side pivotal member, the rack-side pivotal member has a rack-side abutment surface that rotates together with the rack-side pivotal member, the wall-side pivotal member has a wall-side abutment-receiving surface fixed to the wall-side pivotal member and abutting the rack-side abutment surface, and it is preferable that at least one of the rack-side abutment surface or the wall-side abutment-receiving surface has a concave or convex portion. This makes it possible to limit unexpected rotation of the rack. [Effects of the Invention]

[0015] As described above, according to the bicycle parking device of the present invention, the elastic force of the stopper pedal allows the stopper pedal to press against the ground and move away from the ground, so that unnecessary elastic members can be eliminated and the structure of the stopper device can be simplified.

[0017] Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings, however, the present invention is not limited to the following embodiment.

[0018] (First embodiment) 1 to 9 show a bicycle parking device 100 according to a first embodiment of the present invention. The bicycle parking device 100 mainly comprises one or more racks 10, a stopper device 1 provided for each rack 10, and a pivot part 14 that connects the front end of the rack 10 to a wall surface 30 erected in front of the rack 10. As shown in FIG. 7, when multiple racks 10 are provided, one bicycle 20 is placed on each rack 10 for storage. However, the bicycle parking device of the present invention may also comprise only one rack 10.

[0019] The rack 10 is formed by bending a metal plate to form a U-shaped trough with an upwardly open cross section, and has a U-shaped (channel-shaped) opening 12 at its rear end. The bottom surface of the rack 10 is provided with a front wheel storage hole 10a, which is an elongated hole large enough to fit approximately the lower one-third of the front wheel 22 of a bicycle 20, and collar-like portions 12a, 12a (see FIG. 7) are formed by spreading the upper ends of the left and right side walls of the opening 12 outward. The front end 10b of the rack 10 is formed into a pointed shape in a plan view by connecting the front ends of the left and right side walls, and is configured to hold the front wheel 22. A front end cover 10c made of a flat U-shaped plate is placed over the front end 10b of the rack 10.

[0020] At the tip of the rack 10, a pivot part 14 is provided that pivotally supports the rack 10 so that the rack 10 can rotate in the horizontal direction.

[0021] The pivot portion 14 includes a rack-side pivot member 141 fixed to the rack 10, a wall-side pivot member 142 fixed to the wall surface 30, and a vertical pivot axis 50 connecting the wall-side pivot member 142 and the rack-side pivot member 141 so as to rotate the rack-side pivot member 141 horizontally relative to the wall-side pivot member 142.

[0022] As shown in Fig. 9, the rack-side pivotal support member 141 has a U-shape that opens to the front (left side in Fig. 9) in side view, and the wall-side pivotal support member 142 has a U-shape (hereinafter referred to as an inverted U-shape) that opens to the rear (right side in Fig. 9). The rack-side pivotal support member 141 is made up of upper and lower flanges (rack-side upper flange 141a, rack-side lower flange 141c) and a web (rack-side web 141b) that connects the flanges. The wall-side pivotal support member 142 is also made up of upper and lower flanges (wall-side upper flange 142a, wall-side lower flange 142c) and a web (wall-side web 142b) that connects the flanges.

[0023] The rack side pivot member 141 and the wall side pivot member 142 are connected so that the rack side upper flange 141a is placed on the wall side upper flange 142a and the rack side lower flange 141c is placed on the wall side lower flange 142c (see Figure 9).

[0024] The rotating shaft 50 is shaped like a headed nail and is inserted through through-holes 141d and 142d that vertically pass through the rack-side upper flange 141a and the wall-side upper flange 142a, and through-holes 141e and 142e that vertically pass through the rack-side lower flange 141c and the wall-side lower flange 142c, to connect the rack-side pivot member 141 and the wall-side pivot member 142, and to pivotally support the rack 10 so that it can rotate horizontally. The rotating shaft 50 is prevented from coming off by a split pin 50a.

[0025] A front wheel support part 13 that supports the front wheel 22 from below is provided below the front wheel storage hole 10a of the rack 10. The front wheel support part 13 is formed by bending a plate material into a V shape in which the distance between the left and right side walls narrows as it goes downward, and is configured to support the front wheel 22 of a bicycle stored in the front wheel storage hole 10a from below.

[0026] At the rear end of the rack 10, guide rollers 16 consisting of a pair of left and right horizontal wheels are provided from the side walls to both sides (see Figures 2 and 7). By providing a pair of left and right guide rollers 16, it is possible to prevent the rack 10 from falling over due to the tilt of the bicycle when the rack 10 rotates around the rotation axis 50.

[0027] As shown in FIG. 2, the stopper device 1 is formed by bending a long plate made of elastic metal such as spring steel, and includes a stopper pedal 11 and a friction member 17 connected to the rear end of the stopper pedal 11.

[0028] The stopper pedal 11 is provided with an arm 18 that is fixed to the bottom of the rack 10 by means of bolts and nuts, welding, etc., and that extends rearward from the opening 12, and a leg 19 that extends downward from the arm 18. The leg 19 may extend from a midpoint in the fore-and-aft direction of the arm 18, but it is preferable in terms of manufacturing costs to form the leg 19 integrally with the arm 18 and have it extend from the rear end of the arm 18.

[0029] The arm 18 is composed of a joint 18a that is joined to the rear end of the bottom wall of the rack 10, an inclined portion 18b that continues to the rear of the joint 18a and becomes higher toward the rear, and a horizontal portion 18c that continues to the rear of the inclined portion 18b and extends approximately horizontally from the inclined portion 18b. As shown in Figure 2, the inclined portion 18b is inclined so that its rear side (the right side in Figure 2) is higher with respect to the ground 40.

[0030] The arm 18 elastically deforms downward due to the weight of the bicycle 20 passing over the stopper pedal 11. When the arm 18 elastically deforms downward, the rear end of the leg 19 extending downward from the arm 18 comes into contact with the ground 40. This causes frictional resistance in the leg 19, preventing the rack 10 from rotating.

[0031] The leg portion 19 is composed of a load transmission portion 19a extending downward from the rear end of the horizontal portion 18c, and a folded portion 19b bent at the lower end thereof in the thickness direction.

[0032] The load transmission portion 19a of the leg portion 19 is preferably inclined upward toward the front (to the right in FIGS. 2(a) and 2(b)) in both the state in which the bicycle wheel is not placed on the stopper pedal 11 in FIG. 2(a) and the state in which the bicycle wheel is placed on the stopper pedal 11 in FIG. 2(b). This allows the bicycle wheel to be smoothly inserted and removed. Furthermore, when the bicycle wheel is placed on the stopper pedal 11 (see FIG. 2(b)), the angle α that the load transmission portion 19a makes with the vertical direction is preferably greater than 0 degrees and less than 45 degrees. This allows the weight of the bicycle to be transmitted to the ground 40 more efficiently.

[0033] The folded portion 19b of the leg portion 19 may be folded back toward the rear side of the rack 10, but is preferably folded back toward the front side of the rack 10 as in the illustrated example. In this way, the folded portion 19b does not interfere with the wheel riding up onto the stopper pedal 11.

[0034] Furthermore, by folding the folded portion 19b forward, when the weight of the bicycle is applied to the folded portion 19b, the folding angle θ is deformed in a direction that reduces the folding angle θ, and the elastic force generated in the folded portion 19b allows it to efficiently press against the ground 40. In addition, it is preferable that the angle α of the folded portion 19b with respect to the vertical line is within ±10 degrees when the bicycle wheel is riding on the stopper pedal 11 (see FIG. 2(b)). This allows the friction member 17 to be pressed against the ground 40 efficiently. The friction member 17 is made of natural or synthetic rubber and has a generally cylindrical shape, and the male thread of a bolt protruding from the top surface so that it cannot be removed is passed through a through-hole (not shown) in the folded-back portion 19b and fixed with a nut. The underside of the friction member 17 is arranged so that when the bicycle rides up onto the stopper device 1 and hits the ground 40, the entire surface of the underside of the friction member 17 comes into contact with the ground 40.

[0035] The bicycle parking device 100 may have multiple racks instead of one (see FIG. 7). When the bicycle parking device 100 has multiple racks, it is preferable that the multiple racks 10, 10, ... are arranged alternately with high and low front ends 10b, as shown in FIG. 8, so that the handlebars of the bicycles 20 stored in adjacent racks 10 are not impacted.

[0036] (How to use the bicycle parking device 100 and the effects of each part) When parking bicycle 20 in bicycle parking device 100, front wheel 22 of bicycle 20 is placed on rack 10 via stopper pedal 11 of stopper device 1, as shown in Figure 3. Leg 19 extends downward and rearward at its rear end, allowing the bicycle wheel to be lifted along its slope, and arm 18 extends rearward from opening 12, allowing the wheel to be guided back into opening 12. When the front wheel 22 of the bicycle 20 rides up to about the arm portion 18, as shown in Figure 3, the weight of the front wheel 22 of the bicycle 20 causes the stopper pedal 11 to deform downward, and the friction member 17 attached to the folded portion 19b of the leg portion 19 comes into contact with the ground 40. At this time, the elastic force of the stopper pedal 11 trying to return to its original shape presses the friction member 17 against the ground 40. In this state, if an attempt is made to rotate the rack 10 horizontally, frictional resistance is generated in the friction member 17, preventing rotation around the pivot portion 14. As a result, a user attempting to carry in the bicycle 20 can safely carry the bicycle 20 onto the rack 10.

[0037] 4 shows a state in which the front wheel 22 of the bicycle 20 has passed the stopper pedal 11. In FIG. 4, the stopper pedal 11 is released from the load of the front wheel 22, and the friction member 17 is separated from the ground 40. In other words, the elastic force that attempts to return the stopper pedal 11 to its original shape also acts in a direction that separates the friction member 17 from the ground 40.

[0038] In this way, since the stopper pedal 11 has elasticity, the elastic force of the stopper pedal 11 can be made to perform both the function of pressing against the ground 40 and the function of returning the stopper pedal 11 to its original position, and therefore the number of parts in the stopper device 1 can be reduced compared to when these two functions are performed by different elastic members.

[0039] In this way, when friction member 17 is separated from ground surface 40, rack 10 can be easily rotated horizontally. With front wheel 22 loaded onto rack 10, the user can rotate rack 10 along with bicycle 20, and load rear wheel 24 while avoiding adjacent bicycles.

[0040] Furthermore, the inclined portion 18b of the stopper pedal 11 is inclined with respect to the ground 40 so that the rear side is higher, so that the front wheel 22 can be prevented from rolling toward the rear side of the rack 10.

[0041] 5 shows the state in which bicycle 20 is ridden further into rack 10, with rear wheel 24 climbing up stopper pedal 11. As with the case in which front wheel 22 climbs up, arm 18 elastically deforms downward due to the weight of bicycle 20, and friction member 17 locks rack 10 from rotating horizontally.

[0042] Figure 6 shows the state where the rear wheel 24 has passed the stopper pedal 11. The lock provided by the friction member 17 is released. When the bicycle 20 is moved to the tip of the rack 10, the front wheel 22 is accommodated in the front wheel accommodation hole 10a and the front wheel support portion 13, completing the loading of the bicycle. When the front wheel 22 of the bicycle 20 is accommodated in the front wheel support portion 13 (see Figure 1), the lock provided by the friction member 17 is released, so the user can rotate the rack 10 to move it to an appropriate position.

[0043] FIG. 7 is a plan view showing a state in which bicycles 20 are mounted on a plurality of racks 10, and shows that the racks 10 can rotate around the pivots 14. As shown in FIG.

[0044] The rack 10 on the far right of Figure 7 (top of Figure 7) shows a state in which it has rotated counterclockwise, the rack 10 on the far left shows a state in which it has rotated clockwise, and the rack 10 shown in the middle shows a state in which it has not rotated in either direction.

[0045] As described above, the rack 10 can rotate freely when the front wheel 22 of the bicycle 20 is placed on the rack 10, but if the rotation angle becomes too large, there is a risk of contact with other bicycles 20 parked on either side.

[0046] Therefore, in the bicycle parking device 100, when the rack 10 rotates around the pivot part 14 by more than a predetermined angle, the tip of the rack 10 (the tip of the rack-side pivot member 141) abuts against the wall surface 30, stopping the rotation of the rack 10. In the illustrated example, the tip of the rack 10 (the tip of the rack-side pivot member 141) has a rounded rectangular shape, but it is not limited to this, and may also have an arc shape or an ellipse shape as long as it can abut against the wall surface 30 to prevent rotation.

[0047] (Second embodiment) FIG. 10 shows a bicycle parking device 200 according to a second embodiment of the present invention. The bicycle parking device 200 is provided with a stopper device 1 at the rear end of the rack 10, as well as a stopper device 1f at the middle in the fore-and-aft direction. The stopper device 1f is provided at a position where the front wheel 22 of the bicycle 20 will climb over the rear stopper device 1 and before the rear wheel 24 approaches the rear stopper device 1. By providing the stopper device 1f at this position, the section over which the rack 10 may rotate unexpectedly can be shortened. In this embodiment, components common to the first embodiment are designated by the same reference numerals and will not be described again.

[0048] (Third embodiment) 11 shows a bicycle parking device 300 according to a third embodiment of the present invention. In the bicycle parking device 300 according to the third embodiment, the rack-side pivotal support member 141 has a rack-side abutment surface 141s, the wall-side pivotal support member 142 has a wall-side abutment receiving surface 142s that abuts against the rack-side abutment surface 141s, and at least one of the rack-side abutment surface 141s and the wall-side abutment receiving surface 142s has a recess 9b or a protrusion 9a. A protrusion is a portion that protrudes from a surface, and a recess is a recessed portion. In this embodiment, the same reference numerals as in the first embodiment are used for other components common to the first embodiment, and description thereof will be omitted.

[0049] Circular members (rack-side upper circular member 15a and rack-side lower circular member 15e) are fixed to the lower surfaces of upper and lower flanges 141a and 141c of the rack-side pivotal member 141. Circular members (wall-side upper circular member 15b and wall-side lower circular member 15f) are fixed to the upper surfaces of upper and lower flanges 142a and 142c of the wall-side pivotal member 142.

[0050] The rack-side upper circular member 15a and the rack-side lower circular member 15e are connected so as to be placed on the wall-side upper circular member 15b and the wall-side lower circular member 15f.

[0051] The rotation shaft 50 passes through the through-hole 141d (142d, 141e, 142e) of the flange (see FIG. 9), and also passes through the through-hole 15d of the circular member 15a (15b, 15e, 15f) (see FIG. 11).

[0052] The rack-side pivotal member 141 has rack-side contact surfaces 141s on the lower surfaces of the rack-side upper circular member 15a and the rack-side lower circular member 15e. The wall-side pivotal member 142 has wall-side contact-receiving surfaces 142s on the upper surfaces of the wall-side upper circular member 15b and the wall-side lower circular member 15f.

[0053] The rack-side contact surface 141s, which rotates together with the rack-side pivot member 141, and the wall-side contact-receiving surface 142s, which is fixed to the wall-side pivot member 142, face each other and contact each other (see FIG. 12(b)). At least one of the rack-side contact surface 141s or the wall-side contact-receiving surface 142s has a recess 9b or a protrusion 9a, and the recess 9b or the protrusion 9a has a triangular cross section (see FIG. 12(a)).

[0054] When either the rack side contact surface 141s or the wall side contact receiving surface 142s is in contact with the rack while being provided with the recess 9b or the protrusion 9a, the frictional resistance generated when the rack 10 rotates becomes larger than when neither the rack side contact surface 141s nor the wall side contact receiving surface 142s is provided with the recess 9b or the protrusion 9a, thereby restricting the rotation of the rack 10.

[0055] The rack side abutment surface 141s having the recess 9b or the protrusion 9a may be provided on the lower surfaces of the rack side upper flange 141a and the rack side lower flange 141c, rather than on the lower surfaces of the rack side upper circular member 15a and the rack side lower circular member 15e.

[0056] The wall-side contact receiving surface 142s having the recessed portion 9b or the protruding portion 9a may also be provided on the upper surfaces of the wall-side upper flange 142a and the wall-side lower flange 142c, rather than on the upper surfaces of the wall-side upper circular member 15b and the wall-side lower circular member 15f. Even in such an embodiment, the rack-side contact surface 141s and the wall-side contact receiving surface 142s face each other and contact each other, so that frictional resistance occurs when the rack 10 rotates, thereby limiting the rotation of the rack 10.

[0057] As shown in FIG. 12(a), the rack-side contact surface 141s and the wall-side contact-receiving surface 142s are preferably provided with recesses 9b or protrusions 9a with a triangular cross section that extend radially from the center of rotation. The recesses 9b or protrusions 9a may be provided only on a portion of the rack-side contact surface 141s or the wall-side contact-receiving surface 142s, rather than on the entire surface. Specifically, the recesses 9b or protrusions 9a may be provided only on the rack-side contact surface 141s or the wall-side contact-receiving surface 142s that come into contact when the rack 10 is rotated by a predetermined angle or more from a position where the rack 10 is at an angle of approximately 90 degrees with the wall surface 30 (see the middle part of FIG. 7). This suppresses rotation of the rack 10 when rotated by a predetermined angle or more, and prevents the handlebars of bicycles 20 stored on adjacent racks 10 from being impacted.

[0058] The recesses 9b or protrusions 9a may be in a grid pattern rather than a radial pattern extending from the center of rotation.The recesses 9b or protrusions 9a may be in a dot pattern dispersed on a surface rather than a linear pattern such as a radial or grid pattern.

[0059] The rack-side contact surface 141s and the wall-side contact receiving surface 142s need only be configured to rotate relative to each other while in contact, and are not limited to flat surfaces such as squares or circles, but may also have a U-shaped cross section or a part of a cylindrical or spherical surface.

[0060] (Other embodiments) As described above, the bicycle parking device of the present invention is not limited to the above-described embodiment. For example, the stopper pedal 11 may be elastically deformed only partially, rather than entirely. For example, only the arm portion 18 or only the inclined portion 18b may be made of an elastic material, with the rest being rigid. Furthermore, the stopper pedal 11 is not limited to being plate-shaped, but may also be rod-shaped. The arm portion 18 may not have the inclined portion 18b, and the leg portion 19 may not have the folded portion 19b. The rack 10 may slide horizontally along a rail. The front end portion 10b may not abut against the wall surface 30 when sliding horizontally. The pivot portion 14 may be attached to the ground 40 instead of the wall surface 30. A different wall surface 30 may be provided for each rack 10. [Explanation of symbols]
