Description

  The present invention relates to an individual lock type bicycle parking apparatus suitable for use in a bicycle parking lot.

  In recent years, the problem of abandoned bicycles in urban areas and suburban stations has been serious, but the construction of bicycle parking facilities has gradually been promoted along with redevelopment in front of the station, and large bicycle parking lots have been developed by local governments and private companies. It has been maintained. However, with the increase in size, personnel expenses have been incurred for deploying a large number of bicycle parking lot personnel to monitor unauthorized use and to guide inappropriate use. Also, often during rush hours in the morning, rushing users force their bicycles into the bicycle parking device, so breakdowns and damage to the bicycle parking device occur constantly, increasing maintenance costs. Is also true.

  In addition, recent bicycles are used for commuting and attending school, and not only normal 26-inch and 28-inch utility vehicles with large wheel sizes but also folding bicycles with wheel sizes of 20 inches or less are popular. Therefore, the bicycle parking apparatus is required to be able to park properly and securely lock the wheel tires of various sizes.

Therefore, as described in, for example, Patent Document 1, a pair of saddle-shaped members that can be closed with a part of a bicycle wheel being sandwiched are determined in advance from a horizontal direction at a predetermined height. A bicycle parking device was developed that was fixed by tilting upward at a high elevation angle.
JP 2006-56396 A

  However, the bicycle parking device described in Patent Document 1 has the following problems.

<Danger of riding>
FIG. 11 shows a normal parking state of a bicycle BS2 having folding 16-inch wheels. In the parking device 100 as in the conventional patent document 1, the saddle-type lock portion 101 is shown. The height is set to be almost equal to the height H1 (about 200 mm) of the radius of the 16-inch wheel BK. When parking, the front wheel tire BK is made to enter the wheel guide 102 along the wheel guide 102, and if it is advanced as it is, the front wheel tire BK comes into contact with the wheel detection slider 105 of the wheel holding portion 104 of the lock device 103 and further advances the bicycle. Then, the wheel detection slider 105 is pressed and an internal switch (not shown) is turned on, so that the front wheel tire BK is detected, and the arm having the saddle type lock portion 101 operates to lock the front wheel tire BK in a state in which it cannot be withdrawn. It is configured to.

  However, when the bicycle BS2 is vigorously advanced to the bicycle parking device 100, the front tire BK advances even if the front wheel tire BK comes into contact with the wheel detection slider 105 and the wheel detection arm is pressed into a detection state. Since the front tire BK rotates and travels so as to ride on the surface of the wheel detection slider 105 even after the wheel detection slider 105 is pushed down, the riding state as shown in FIG. In such a state, it was very dangerous for the user.

  In addition, when the vehicle rides on the position shown in FIG. 12 and stops, even if the wheel detection slider 105 is pushed and the wheel detection is in an ON state, the saddle type lock portion 101 of the lock device 103 is used for the rim BT or tire of the front wheel tire BK. If BK is scratched as a result of BK being caught, vibrations and abnormal noise during subsequent brake operations, abnormal wear of the brake shoe, etc. may occur. In addition, there is a risk of causing puncture in the worst case when the tire BK is sandwiched.

<Unauthorized bicycle parking>
Furthermore, in the conventional parking device 100, the front wheel tire BK can be put on the lock device 103 even when the wheel detection slider 105 does not detect the front tire BK intentionally as shown in FIG. In addition, if the stand ST on the rear wheel side is set up at the same time, the bicycle BS2 can easily maintain its posture, so even if the front tire BK is not detected, the bicycle is parked as usual. Therefore, there is a problem that illegal parking is possible in such a state.

  In these conventional examples, the folding bicycle BS2 having 16-inch wheels is exemplified. However, it is of course possible to perform the same riding and illegal parking in a bicycle having general 26-inch wheels. It is.

<Strength>
In addition, as shown in FIG. 14, it is possible to park illegally by leaving the front tire BK just inserted into the wheel guide 102 of the parking device 100 without properly entering the parking device 100. Then, when an external force that causes the bicycle BS2 to fall is applied, a great load is applied to the joint 110 of the wheel guide 102, so that the weld joint or the like is broken or the joint 110 of the wheel guide 102 is broken. There was also a problem that the neighborhood was easily deformed, and maintenance and repair were expensive.

  The present invention has been developed to solve the above-mentioned problems of riding-up, illegal parking, and strength, and the technical problem is that even if the bicycle is vigorously entered, the front tire The front wheel tire can be locked safely and securely without overrunning on the locking device, and the locking device must lock the front tire even when the front tire rides on the locking device. To provide a bicycle bicycle parking device that prevents illegal bicycle parking and enhances the strength of the bicycle parking device so that it does not break easily even if an external force such as a bicycle falls is applied. It is.

(1) In order to solve the above technical problem, according to the present invention, when the front wheel tire of the bicycle is guided to the left and right guide rail portions and pushed into a predetermined portion, the locking device is provided. A bicycle parking apparatus configured to lock a front wheel tire, wherein the front wheel tire rides on the lock device by fitting the front wheel tire of the bicycle moving forward into the upper portion of the lock device. The overrun regulation guide part which can regulate the overrun which advances is characterized by standing.

(2) Further, according to the second aspect of the present invention, as described in the second aspect, the overrun restricting guide portion is a rod-shaped or pipe-shaped member so that the front portion side of the front wheel tire that moves forward can be fitted. The overrun restricting guide portion is bent and formed into an inverted U-shape, and the length dimension from the locking device to the upper-end folded portion bent and formed in the inverted U shape is at least subject to parking. It is characterized by being set shorter than the standard diameter dimension of the front wheel tire in the bicycle.

(3) Further, according to the present invention, as described in claim 3, the interval between the rod-like or pipe-like members constituting the overrun restricting guide portion into which the front portion of the front tire that advances is fitted is at least a bicycle. It is characterized in that it is set narrower than the length of the hub axle for attaching the front wheel tire to the front fork or the interval between the tightening nuts attached to both ends of the hub axle.

(4) Further, according to the present invention, as described in the fourth aspect of the present invention, the guide is constituted by guide rails arranged side by side on the left and right, and a tire guide plate that is installed and fixed between the left and right guide rails. The rail part is configured in a generally heft-like shape by integrally connecting a rising slope part inclined obliquely upward from the lowermost entrance and a downward slope part inclined obliquely downward from the apex of the rising slope part. And the left and right guide rails are bent obliquely upward from the middle of the descending slope portion to form a linkage portion into which the front tire of the bicycle fits between both guide rails. The tip ends of the left and right guide rails inclined obliquely upward are extended in the vertical direction while maintaining a parallel spacing, thereby forming an inverted U shape on the upper end side of both guide rails. An overrun restricting guide portion provided with a bent upper end turn-up portion is integrally connected, and at least below the overrun restricting guide portion and in the vicinity of the end portion of the descending slope, the locking device is provided. It is characterized by being inclined to the back.

(5) Further, according to the present invention, as described in the fifth aspect, the lock device includes a case body in which a fitting groove into which a front wheel tire of a bicycle is fitted is formed in a front surface of a central portion, and an interior of the case body. And a pair of saddle-shaped arm bodies attached so as to be able to lock in a state where a part of the front wheel tire fitted in the fitting groove is sandwiched from the left and right, and the front wheel tire fitted in the fitting groove. Is formed by the front wheel tire detector that operates by sandwiching the pair of saddle-shaped arm bodies, while part of the left and right guide rails are arranged on both the left and right sides of the case body with the fitting grooves interposed therebetween. It is characterized by being inserted and fixed vertically.

(6) Further, according to the present invention, as described in the sixth aspect, the locking device includes a position where the front wheel tire of the bicycle is guided by the guide rail and pushed to a predetermined position, and the front wheel tire is the locking device. The front wheel tire pushes the front wheel tire detection body, and the pair of saddle-type arm bodies are connected to the front wheel tire, even if the front wheel tire is pushed into any position of the position restricted by the overrun restriction guide portion. It is characterized in that it is provided so as to be inclined to the back at a height position where the inside of the rim can be pinched and locked.

  According to the means according to claim 1 described in the above (1), even if the bicycle is vigorously entered with respect to the locking device, the front side of the front tire of the bicycle is fitted by the overrun restricting guide portion. Since the overrun in which the front tire rides on the locking device moves forward is restricted, the front wheel tire can be prevented from being removed and the bicycle front wheel tire can be securely locked to the locking device.

  According to each means according to claims 2 and 3 described in the above (2) and (3), for example, when a large-diameter bicycle having a wheel diameter of 28 inches or 26 inches tries to get over the locking device, The upper end folded portion formed in the inverted U shape of the overrun regulation guide part regulates the overrun of the front wheel tire in the upward direction, so that the front wheel tire does not run over the lock device.

  Further, for example, when a front wheel tire of a small wheel bicycle having a wheel diameter of 16 inches tries to get over the lock device, the interval between the rod-like or pipe-like members constituting the overrun restricting guide portion is set to be used for attaching the front wheel. Engaging with both end portions of the hub shaft or a tightening nut restricts overrun in the traveling direction (forward direction) of the front tire and prevents the front tire from overrunning on the locking device. be able to. Therefore, even if the user vigorously enters the bicycle toward the locking device, the bicycle can be parked with the front wheel tire locked safely and securely without causing overrun or the like. Enable.

  According to the means according to claim 4 described in the above (4), the guide rail portion for guiding the front wheel tire of the entering bicycle to the locking device has the entrance side as the rising slope portion, and then the descending slope portion. In order to park the bicycle, first the front wheel tire is lifted to the slope. After climbing the ascending slope part, the front tires will naturally advance and descend along the descending slope part, and then remain in the lock device. Since the bicycle is locked, the bicycle can be securely locked and illegal parking where the front tire is left without being locked by the locking device can be prevented.

Further, according to the means according to claim 4 described in the above (4), the guide rail portion that becomes the traveling path of the front tire of the bicycle is installed between the left and right guide rails and the left and right guide rails. And the overrun restricting guide part formed by bending in an inverted U shape with a guide rail, a locking part following the guide rail, and a folded part at the upper end part. Since one rod-like or pipe-like member can be formed by bending, it is mechanically robust, and the entire device can be made tough and improved in durability. Even for this, it is possible to respond sufficiently.

According to the means according to claim 5 described in the above (5), when the front wheel tire of the bicycle is fitted into the fitting groove provided in the case body of the locking device and the front wheel tire detecting body is pushed, The mold arm can be rotated and locked in a state in which a part of the front wheel tire is sandwiched, and can be held so that it cannot be withdrawn. Further, since a part of the guide rail constituting the overrun restricting guide portion is inserted and fixed in the vertical direction in the case body, the guide rail and the locking device are integrally bent with respect to the external force, thereby improving the strength. As a result, it is possible to prevent a deviation due to a manufacturing error.
The unlocking of the locking device is configured so that the locking device automatically unlocks when the parking fee is settled, for example.

  According to the means according to claim 6 described in the above (6), either the case where the front wheel tire of the bicycle is pushed into a predetermined position or the case where the tire is pushed into the overrun restricting position on the lock device. However, since the saddle type arm body of the locking device pinches and locks the inside of the rim of the front wheel tire and holds it so that it cannot be withdrawn, the bicycle can be driven without turning on the lock by intentionally riding the front wheel tire on the locking device. It is possible to prevent illegal parking that is left unattended, and to prevent the inconvenience that the saddle-type arm body accidentally pinches the rim and the tire when locked.

  As described above, according to the bicycle parking apparatus according to the present invention, both the large-diameter wheel and the small-diameter wheel can be securely locked and parked. It has the advantage that it can be used for parking bicycles of the type, and even when the bicycle is vigorously entered into the bicycle parking device, the overrun regulation guide part prevents wheel overrunning and parks safely. The entire device is strong and durable, and has the economy that maintenance and repair costs can be reduced, and the rim and tire are accidentally caught when locked by the locking device. The advantage of bicycle parking is that it can provide a bicycle parking device that is safe for the user, and that it can prevent illegal parking by leaving the bicycle unattended or parked without turning on detection of the front wheel tires. As bicycle apparatus can exhibit the advantage of improving the sexual, but extremely suitable.

  The embodiment of the bicycle parking apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 is an external view of the bicycle parking apparatus 1 according to the embodiment of the present invention, and FIG. In general, in consideration of space efficiency, the bicycle parking device 1 is configured in two heights as shown in the figure, and used in combination with a number of them in the horizontal direction. However, what is illustrated is an example of implementation, and a plurality of bicycle parking apparatuses 1 made at the same height may be arranged in the horizontal direction, and the selection thereof is arbitrary.

  In each of the above drawings, reference numeral 10 indicates the whole ascending slope portion 10A inclined obliquely upward from the lowermost inlet 10H and the descending slope inclined obliquely downward from the apex of the upward slope portion 10A. The guide rails are integrally formed with the portion 10B, and the guide rails are generally formed in a substantially U-shape. These guide rail portions 10 are respectively connected to the above-described drawings and the line AA in FIG. As shown in FIG. 3 showing each cross-sectional view along the line B-B, the metal guide rails 11 and 12 arranged in parallel at a left and right parallel interval so that the front wheel tire of the bicycle to be parked can be guided. The tire guide plates 13 and 14 made of metal are constructed and welded between them. In addition, as a material of the guide rails 11 and 12, a round bar, a square bar, a hexagon bar, or those hollow pipe materials are used.

  2 and 3 are base materials laid on the road surface of the bicycle parking space at the front and rear, and 4 and 5 are high and low two-stage support stands provided on the base material 3 on the rear side. The guide rail portions 10 are fixed to the front base member 2 at the entrance 10H of the ascending slope portion 10A, and the rear end portion side tire guide plate 14 is attached to the descending slope portion 10B. By fixing to the rear side base material 3 side via the members 15A and 15B, it is configured so that the substantially square shape and each interval are maintained.

  Further, in the figure, reference numeral 10C denotes a connecting portion formed by bending the left and right guide rails 11 and 12 constituting each of the guide rail portions 10 obliquely upward from the middle of the descending slope portion 10B. As shown in FIGS. 9 and 10, the lower part of the front part of the front tire of the bicycle is fitted into the interval between the continuous parts 10 </ b> C in the bottomed state where the side tire guide plate 14 is not installed.

  In FIG. 9, BS1 is a large-diameter bicycle having a normal wheel size of 26 inches or 28 inches, S1A indicates the front tire (front wheel), S1B indicates a rim, and S1C indicates the front of the bicycle BS1. A fork S1N is a nut for fastening a hub shaft (not shown) for attaching the front tire S1A to the front fork S1C.

  7 and 10, BS2 is a small-diameter bicycle having a wheel size of, for example, 16 inches, S2A is a front tire (front wheel) thereof, S2B is a rim, S2C is a front fork of the bicycle BS2, S2N is a nut (overlock knight) for tightening the hub axle S2D (see FIG. 8) for attaching the front wheel tire S2A to the front fork S2C.

  Further, in FIGS. 1 and 2, 10D is an overrun constructed by extending the upper end portions of the left and right guide rails 11 and 12 constituting the connecting portion 10C in the vertical direction further upward while maintaining a distance. The restriction guide portion 10E is an upper end folding portion formed by connecting the left and right guide rails 11 and 12 extending in the vertical direction in an inverted U shape, and the upper end folding portion in the overrun restriction guide portion 10D. An interval distance (length dimension) from 10E to a locking device 20 described later (specifically, an upper end portion of the front wheel tire detection body 25 of the locking device 20) is at least a front wheel tire of a bicycle to be parked. It is made shorter than the standard size (26 inches or 28 inches), and the 26-inch or 28-inch tires of the bicycle pass (over) It has been configured not to run).

  The distance between the left and right guide rails 11 and 12 constituting the overrun restricting guide portion 10D is such that the large and small diameter front wheel tires S1A and S2A can be inserted, but at least the hub shaft of the small diameter front wheel tire S2A. The guide rails 11 and 12 are made narrower than the length of S2D or the entire length of the hub shaft S2D including the fastening nuts S2N and S2N attached to both ends of the hub shaft S2D. Is configured so that the small-diameter front wheel tire S2A cannot pass (overrun). That is, as shown in the sectional view taken along the line DD of FIG. 7 shown in FIG. 8, generally, the inner widths (overlock nut widths) of the tightening nuts S2N and S2N are the same as those of the front tire S2A. It is defined by a width L1 wider than the width W. In many bicycles, a standard product having a dimension of L1 of 100 mm is used. The front forks S2C and S2C which are divided into two are present on the outer side, and the tightening nuts S2N and S2N are further stopped on the outer side of the front forks S2C and S2C.

  In the embodiment of the present invention, the front tire S2A does not pass if the distance between the guide rails 11 and 12 constituting the overrun restricting guide portion 10D is at least smaller than the L2 width. If the width is set to about 60 mm in consideration of the above-mentioned standard, since the width of the overlock nut is smaller than 100 mm, the progress of the front wheel tire SA can be reliably regulated. In addition, since the tire width of the bicycle is about 54 mm at the maximum in the JIS standard, the distance between the guide rails 11 and 12 can be in the range of 54 to 100 mm, and 60 mm is preferable.

  Next, a reference numeral 20 indicates a lock device provided at the upper end portions of the support bases 4 and 5 and on the lower portion of the overrun restricting guide portion 10D so as to be inclined upward. The locking device 20 is parked on the front portion as is apparent from the plan view of FIG. 4 with the top cover case removed and the sectional view taken along the line CC of FIG. 4 shown in FIG. A case body 21 having a recessed fitting groove 22 into which a front wheel tire of a bicycle is fitted, and the front wheel tire fitted into the fitting groove 22 from the left and right inside the case body 21 can be locked. A pair of saddle-shaped arm bodies 23, 23 and a front wheel tire detection slider 25 that is pushed by the front wheel tire fitted in the fitting groove 22 and slides to the left in the drawing are provided.

  The pair of saddle-shaped arm bodies 23, 23 are provided with detection projections 23B, 23B on the inner side of the center portion, and the front wheel tire detection body as a front wheel tire detection body is detected by the entering front wheel tire S1A or S2A. When the slider 25 is guided by the slider shaft 25T and pushed leftward in the drawing, the projections 23B and 23B are pushed, and the support shafts 24 and 24 are moved while the spring-shaped arm bodies 23 and 23 are extended. 4 is rotated to the position of the two-dot chain line in FIG. To turn on the switch. Then, the solenoid 29 attached in the case body 21 is de-energized (OFF), and the locking lever 27 is rotated to the position indicated by the two-dot chain line in FIG. Since it is interposed between the parts, it is configured such that the opening and closing of the saddle-shaped arm bodies 23 and 23 thereafter is restricted and the locked state is maintained.

  In order to unlock the above-mentioned locked state, a coin is inserted into a bicycle parking fee adjustment machine (not shown) provided in the bicycle parking lot, and the number of the bicycle parking device 1 is input to excite the solenoid 29 ( ON) and the locking lever 27 is rotated to the position indicated by the solid line in FIG. 5, so that the two-armed arm bodies 23, 23 are opened and rotated to the position indicated by the solid line in FIG. The lock on the front tire S1A or S2A can be released.

  The solenoid 29 of the present embodiment is a latch solenoid that can selectively operate in the released state and the attracted state of the plunger portion. However, the solenoid and the spring that are attracted by normal energization and opened in the non-energized state are assumed. It is also possible to use a rotary solenoid. Further, the guide rails 11 and 12 are inserted into the case body 21 of the locking device 20 from the side wall of the fitting groove 22 and fixed to the case body 21 as shown in FIG. Therefore, the front wheel tire S1A or S2A that has entered between the guide rails 11 and 12 constituting the overrun restricting guide portion 10D is inserted into the fitting groove 22 of the lock device 20. It can be securely guided and locked in.

  Further, by selecting a material (for example, a stainless steel strip) having excellent wear resistance as a material constituting the cover body 21B for fixing the guide rails 11 and 12 through the locking device 20, the front wheel It is possible to protect the front edge portion of the locking device 20 directly hit by the tire S1A or S2A and the peripheral edge portion of the fitting groove 22 from wear or damage.

  Next, FIG. 6 is a configuration diagram for explaining the positional relationship of each member constituting the present invention. In the figure, the assumed small wheel radius is RS, the large wheel radius is RL, and RS = 16 inch wheels. Assuming about 200 mm, RL = 26 inches wheels, about 330 mm. Moreover, 355 mm is assumed as RMax = 28 inches as the assumed maximum wheel radius. Furthermore, in FIG. 6, the positional relationship of the locking device 20 provided at a high position is described. However, even in the locking device 20 at a low position, the height H from the descending slope portion 10 </ b> B to the saddle-shaped arm body 23 and the descending slope are also illustrated. The elevation angle α formed by the portion 10B and the locking device 20 and the inclination angle β of the descending slope portion 10B are all the same.

  Further, in the present invention, unlike the bicycle parking device 100 described in Patent Document 1 described above, the height H from the descending slope portion 10B to the saddle arm 23 is set to be larger than the small-diameter wheel radius RS. is doing. Specifically, the above H is 240 mm, preferably 230 to 250 mm.

  Next, the operation of the present invention will be described. FIG. 9 (1) shows a state in which the large-diameter bicycle BS1 is parked on the bicycle parking apparatus 1 according to the present invention as usual. In the case of a bicycle parked, the front arm tire detecting slider 25 of the locking device 20 detects the front wheel tire S1A, and the saddle type arm body 23 sandwiches the spoke peripheral portion on the inner side of the rim S1B of the front wheel tire S1A. Locked to an impossible state.

  On the other hand, FIG. 9 (2) shows a state in which the front wheel tire S1A is about to ride on the locking device 20 by moving (entering) the large-diameter bicycle bicycle BS1 from the state of FIG. As shown in the figure, the upper outer peripheral surface of the front tire S1A is restrained by the upper end turn-up portion 10E of the overrun restricting guide portion 10D, and the overrun in the upward direction is restricted. Further advancement of BS1 is restricted, and locking of the front tire S1A by the locking device 20 is performed as usual.

  9 (1) and 9 (2), a bicycle with a wheel size of 26 inches is shown as the large-diameter bicycle bicycle BS1, but in a 28-inch bicycle, the gap between the upper end turn-up portion 10E and the front tire S1A is narrow. Therefore, overrun regulation is performed earlier than the illustrated 26-inch bicycle. On the other hand, as the wheel size is reduced to 24 inches and 22 inches, the distance between the upper end turn portion 10E and the front wheel tire S1A increases, and the moving distance to ride on the lock device 20 increases. If the distance (distance) between the front wheel tire detection slider 25 and the upper end turn-up portion 10E is configured to be narrower (shorter) than the wheel size of the bicycle to be parked, the front tire S1A is secured to the lock device 20. Since it is not possible to ride over, overrun can be reliably regulated.

  FIG. 10 shows a parking state of the small-diameter bicycle BS2, specifically, a folding bicycle having a wheel size of 16 inches is shown.

  FIG. 10 (1) shows a state where the small-diameter bicycle BS2 is parked on the bicycle parking device 1 as usual, and the front wheel tire detection slider 25 of the lock device 20 detects the front wheel tire S2A. A saddle type lock part 23A at the tip of the mold arm 23 sandwiches the spoke peripheral part inside the rim S2B of the front tire S2A and locks it in a state in which it cannot be withdrawn.

  On the other hand, FIG. 10 (2) shows a state in which the front wheel tire S2A is about to ride on the lock device 20 by moving (entering) the small-diameter bicycle BS2 from the state of FIG. 10 (1) as it is in the traveling direction. As shown in the figure, the length of the hub shaft S2D (see FIG. 8) for attaching the front tire S2A to the front fork S2C, or between the tightening nuts S2N and S2N attached to both ends of the hub shaft S2D. The distance is longer than the distance between the left and right guide rails 11 and 12 constituting the overrun restricting guide portion 10D, and the nuts S2N and S2N for tightening at both ends of the hub shaft S2D or both sides are formed. Is stopped by the guide rails 11 and 12 to stop the overrun, and further progression of the small-diameter bicycle BS2 is restricted, and the locking device 20 The lock of the front wheel tire S2A due is carried out as usual. Further, in this locked state, the saddle type lock part 23A at the tip of the saddle type arm body 23 sandwiches the spoke peripheral part inside the rim S2B of the front wheel tire S2A and locks it in a state in which it cannot be withdrawn. .

  Further, in any of the cases shown in FIGS. 9 and 10, the front tires S1A and S2A effectively press the front tire detection slider 25 of the locking device 20 to be in the ON state, and the front tire S1A or S2A is For example, as shown in FIG. 13, it is not possible to perform illegal parking, such as riding on the locking device 20 and leaving it alone, so that illegal parking can be prevented.
