Description

  The present invention relates to a bicycle parking apparatus that moves laterally on a fixed rail on which an elongated storage rack for mounting a bicycle is horizontally disposed.

  A horizontally moving bicycle parking apparatus is simple in structure and operation, has a high storage efficiency of bicycles, and is relatively inexpensive for installation and maintenance. Therefore, outdoor bicycle parking lots and condominiums that are permanently installed on walkways and parks etc. -It is widely used regardless of indoor bicycle parking lots established in apartments, etc. and underground bicycle parking lots attached to buildings and underground stations. Moreover, it is used also for the lower end bicycle storage device in the upper and lower two-stage type bicycle support machine.

  In such a laterally moving parking apparatus, the storage rack is moved horizontally along a pair of parallel fixed rails, or by one fixed rail and one or more castors (ie auxiliary wheels). Even if the user is a child or an elderly person, it is easy to carry out bicycle parking work. On the other hand, when the bicycle is carried in, the storage rack tends to slip sideways (that is, escape in the lateral direction), which may cause a mistake in carrying the bicycle, or cause damage to the storage rack or bicycle or injury to the user. There is.

  In order to solve such a problem, the applicant of the present application is a lifting pillar (lifting body) for lifting and landing the caster (auxiliary wheel) by lowering, grounding, rising and retracting the tip end portion of the applicant in Patent Document 1 And a foot pedal (operation member) for lowering the elevating post, and a parking mechanism provided with a return mechanism for returning the elevating post by raising the bicycle into the storage rack. As a result, the user of the bicycle parking apparatus depresses the foot pedal and stops the lateral movement of the storage rack in an empty vehicle state, and then when the bicycle is carried into the storage rack, the return mechanism operates and the elevating support rises and the storage rack Horizontal movement is possible. Therefore, when the bicycle is carried in, the storage rack does not shift sideways to prevent the occurrence of loading errors, and after the completion of carrying in, the storage rack can be smoothly moved laterally. Improve.

  However, since the frictional force generated between the tip end surface of the elevating column and the ground contact surface (ground surface) largely depends on the condition (material, roughness, humidity, etc.) of these surfaces, for example, the ground contact surface gets wet by rain If this happens, even if only a slight external force (for example, wind power) acts, the elevating column may slide on the ground plane. As described above, even a slight change in the weather can not ignore the influence on the lateral displacement of the storage rack at the time of carrying in the bicycle, and there is room for further improvement in Patent Document 1 as well.

  An object of the present invention is to provide a bicycle parking apparatus capable of more reliably stopping lateral displacement of a storage rack at the time of carrying in a bicycle and further improving the safety and workability of the bicycle parking operation.

Solution to the problem and effect of the invention

In order to solve the above problems, the present invention is
A storage rack having a wheel entrance for carrying a bicycle formed at one end in the longitudinal direction, and a fixed rail horizontally disposed on the ground surface along a lateral direction intersecting the longitudinal direction of the storage rack And the storage rack is mounted movably in the lateral direction along the fixed rail,
The storage rack further includes a plate-like member (for example, a braking plate) fixedly arranged on the ground surface in parallel with the fixed rail on one end side in the longitudinal direction of the storage rack.
In the storage rack,
On the bottom side of the storage rack, an auxiliary wheel (for example, a caster) that can roll in the lateral direction while supporting the storage rack when it is in a landing state with the ground surface;
In the vicinity of the auxiliary wheel, the plate-like member is in contact with the plate-like member at a projecting position where its tip projects downward below the lower edge of the auxiliary wheel, and at the retracted position retracted above the lower edge An elevating body (e.g., elevating column) that can be changed to a state of being separated from the member and waiting;
An operation member (for example, a foot pedal) operated artificially only to displace the lift body from the retracted position to the projecting position;
A return mechanism for returning the elevating body from the projecting position to the retracted position based on the loading of the bicycle into the storage rack;
The surface of the plate-like member is formed on a pressure-contacted portion pressed by the tip end surface of the tip end portion of the elevating body, and a plurality of projections (for example, protruding pieces) protruding upward from the surface are respectively The side surfaces of the projection are provided as a convex contact portion (that is, a projection side surface) in contact with the outer peripheral surface of the tip end portion of the elevating body in a straight line at a predetermined pitch along the lateral direction.
In an empty state where the bicycle is not mounted on the storage rack, the elevating body is displaced from the retracted position to the projecting position by the distal end surface pressing the pressure receiving portion based on an artificial operation of the operation member. When the auxiliary wheel is in a floating state and the tip surface receives a lateral external force and a lateral slip occurs with respect to the pressure-contacted portion, the outer peripheral surface contacts the contact portion, thereby causing the storage rack to move. While stopping the lateral movement,
By the operation of the return mechanism based on the loading of the bicycle into the storage rack, the elevating body returns from the projecting position to the retracted position, and the tip end surface is separated from the pressure-contacted portion to ground the auxiliary wheel. And the storage rack can be moved in the lateral direction.

  As described above, when the bicycle is carried in, for example, the ground surface gets wet due to rain and the like, and the storage rack receives the action of the cross wind, whereby the tip end surface of the elevating body is against the pressure-contacted portion Even when skidding occurs, the outer circumferential surface of the elevator moves into contact with the convex abutment (that is, the side surface of the projection), and lateral displacement of the storage rack is reliably stopped, so the safety of parking operation And the workability can be further improved. When the storage rack and the fixed rail are arranged orthogonal to each other in plan view, the storage rack moves laterally in the direction perpendicular to the longitudinal direction, and when arranged diagonally, moves in the diagonal direction Do.

The pitch dimension P of the plurality of contact portions formed on the plate-like member is set larger (P> W) than the maximum lateral width W of the tip end portion of the elevating body,
When the lift is in the extended position, the storage rack is allowed to move laterally within the pitch dimension P of the abutments adjacent to one another.

  Thus, when the lifting body is in the protruding position, when the tip (or storage rack) of the lifting body is moved by P-W (that is, the maximum allowable width of side slip) by the action of external force (for example, wind power), Since it stops in contact with any one of the adjacent convex abutments (that is, the side surfaces of the protrusions), the carrying-in operation of the bicycle can be performed safely.

Moreover, in order to solve the above-mentioned subject, this invention is
A storage rack having a wheel entrance for carrying a bicycle formed at one end in the longitudinal direction, and a fixed rail horizontally disposed on the ground surface along a lateral direction intersecting the longitudinal direction of the storage rack And the storage rack is mounted movably in the lateral direction along the fixed rail,
A plate-like member (for example, a braking plate) fixed and disposed on one end side in the longitudinal direction of the storage rack in parallel with the fixed rail directly or indirectly via an intermediate plate (for example, a base plate) on the ground surface And further
In the storage rack,
On the bottom side of the storage rack, an auxiliary wheel (for example, a caster) that can roll in the lateral direction while supporting the storage rack when it is in a landing state with the ground surface;
In the vicinity of the auxiliary wheel, the plate-like member is in contact with the plate-like member at a projecting position where its tip projects downward below the lower edge of the auxiliary wheel, and at the retracted position retracted above the lower edge An elevating body (e.g., elevating column) that can be changed to a state of being separated from the member and waiting;
An operation member (for example, a foot pedal) operated artificially only to displace the lift body from the retracted position to the projecting position;
A return mechanism for returning the elevating body from the projecting position to the retracted position based on the loading of the bicycle into the storage rack;
The plate-like member is formed with a plurality of through holes having a size allowing the tip of the elevating body to pass therethrough in a straight line along the lateral direction, and the inner peripheral surface of each through hole is the above Configured as a concave contact portion that contacts the outer peripheral surface of the tip end portion of the elevating body,
In the empty vehicle state in which the bicycle is not mounted on the storage rack, the tip end of the elevating body passes through the through hole based on an artificial operation of the operation member, and the tip surface of the tip end is the ground surface or the intermediate plate material By pressing the upper surface as a pressure-contacted portion, the auxiliary wheel is displaced from the retracted position to the projecting position to bring the auxiliary wheel into a levitating state, and the tip end surface receives a lateral external force to cause a side slip against the pressure-contacted portion. In this case, while the storage rack stops moving in the lateral direction by the outer peripheral surface contacting the contact portion,
By the operation of the return mechanism based on the loading of the bicycle into the storage rack, the elevating body returns from the projecting position to the retracted position, and the tip end surface is separated from the pressure-contacted portion to ground the auxiliary wheel. And the storage rack can be moved in the lateral direction.

  As described above, when the bicycle is carried in, for example, the surface of the ground or the upper surface of the intermediate plate gets wet due to rain or the like, and the storage rack receives the action of the crosswind, whereby the tip end surface of the tip of the elevator Even when a side slip occurs with respect to the ground surface or the upper surface of the intermediate plate, the outer peripheral surface of the tip of the elevator moves in contact with the concave contact portion (that is, the inner peripheral surface of the through hole) As a result, the safety and operability of the bicycle parking operation can be further improved. When the storage rack and the fixed rail are arranged orthogonal to each other in plan view, the storage rack moves laterally in the direction perpendicular to the longitudinal direction, and when arranged diagonally, moves in the diagonal direction Do.

The minimum lateral width D of the contact portion formed on the plate member is set to be larger than the maximum lateral width W of the tip end portion of the elevating body (D> W),
When the lift is in the extended position, the storage rack is allowed to move laterally within the minimum width D area of the abutment.

  Thus, when the lifting body is in the projecting position, when the tip (or storage rack) of the lifting body is moved by D-W (that is, the maximum allowable width of side slip) by the action of external force (for example, wind power), Since it comes into contact with and stops anywhere on the concave contact portion (that is, the inner circumferential surface of the through hole), the carrying-in operation of the bicycle can be performed safely.

  In any of the bicycle parking apparatus, the elevation movement stroke S between the protruding position and the retracted position by the elevating body is larger than the height H of the contact portion (S> H).

  As described above, since the lifting and lowering movement stroke S of the lifting and lowering body is larger than the height H of the contact portion (S> H), when the lifting and lowering body is in the retracted position, the storage rack detours above the contact portion Slide movement (horizontal movement) can be performed at high speed.

  The auxiliary wheel is disposed on one end side in the longitudinal direction of the storage rack with respect to the plate-like member.

  As described above, since the auxiliary wheels are located on the rear end side (wheel entrance / outlet side) of the storage rack rather than the plate-like member, strength improvement in the vicinity of the wheel entrance / outlet where weight is received in the storage rack To contribute.

  Hereinafter, an embodiment of the present invention will be described with reference to an example shown in the drawings. FIG. 1 is an overall front view illustrating a schematic structure of a bicycle parking apparatus according to the present invention, FIG. 2 is a plan view, and FIG. 3 is a bottom view. The bicycle parking apparatus 1 shown in FIGS. 1 to 3 has a long bowl shape (see FIGS. 10 and 11) long in the front-rear direction for mounting the front wheel FW and rear wheel RW of the bicycle BCL. The storage rack 2 in which the entrances and exits 2a of the wheels FW and RW are formed at one end (here, the rear end), and horizontal on the ground surface E along the lateral direction (that is, the lateral direction) intersecting the longitudinal direction of the storage rack 2 And a fixed rail 4 disposed on the Specifically, the slide frame 3 fixed to the bottom surface side of the storage rack 2 is installed on the ground surface E, which is a reference surface, via a plurality of (totally eight in the drawing) rollers 5 (rolling elements). It is configured to be movable laterally along the fixed rail 4.

  Furthermore, an elongated rectangular plate-like braking plate 6 (plate-like member) is parallel to the fixed rail 4 at the rear end side which is the one end side of the storage rack 2 in the longitudinal direction (that is, the longitudinal direction of the braking plate 6). Fixedly arranged on the ground surface E with the direction of As described later, the braking plate 6 is used to stop the lateral movement of the storage rack 2.

  As shown in FIG. 2, the storage rack 2 (and the slide frame 3) and the fixed rail 4 diagonally intersect at a predetermined crossing angle θ so that the space can be effectively used to increase the number of bicycles parked. The storage rack 2 is moved laterally in a direction oblique to the longitudinal direction. Although any of the front and rear wheels can be carried in from the entrance 2a of the storage rack 2, in this embodiment, the case of front-loading (that is, carrying in the front wheel FW as the preceding carrying-in wheel) will be described .

  As shown in FIG. 1, the storage rack 2 is provided with a caster 10 (auxiliary wheel), an elevation support 20 (elevation body) and a foot pedal 30 (operation member) on the rear end side which is one end side. Further, a return mechanism 40 is provided straddling from the front end side, which is the other end side, to the rear end side.

  The caster 10 is attached to a caster holding frame 11 fixed to the bottom surface side of the storage rack 2 between the entrance 2 a and the elevating column 20. The caster 10 can roll in the lateral direction while supporting the storage rack 2 in the state of landing on the ground surface E.

  The elevating column 20 is disposed adjacent to the entrance 2a and in the vicinity of the caster 10 so as to be vertically movable along any of the left and right side walls (left side wall in the embodiment) of the storage rack 2 (see FIGS. 7 and 10). The raising and lowering column 20 is in contact with the braking plate 6 at a projecting position where the tip end protrudes below the lower edge of the caster 10 (see FIG. 6), and from the braking plate 6 in a retracted position where it retracts above the lower edge It can be changed to a state of waiting for being separated (see FIG. 9).

  The foot pedal 30 is disposed in association with the elevating post 20 and is artificially depressed only to displace the elevating post 20 from the retracted position to the projecting position (see FIG. 7). The return mechanism 40 returns the lifting post 20 from the projecting position to the retracted position based on the loading of the bicycle BCL into the storage rack 2 (see FIG. 9).

  Specifically, the return mechanism 40 includes a wheel receiver 41 disposed on the front end side of the storage rack 2, a rotation plate 42 (operating member) disposed on the rear end side of the storage rack 2, and the storage rack A connecting rod 43 (connecting member) disposed longitudinally along the bottom wall of 2 and connecting the wheel receiver 41 and the rotating plate 42, and a wheel receiver bridged between the wheel receiver 41 and the storage rack 2 And a tension coil spring 44 (elastic member).

  The wheel support tension coil spring 44 applies an urging force to the wheel support 41 in a direction in which the pivoting plate 42 moves away from the lift post 20 (see FIG. 4). The wheel receiver 41 rotates around the horizontal rotation shaft 41 a by the front wheel FW of the bicycle BCL carried into the storage rack 2 against the urging force of the wheel support tension coil spring 44. The pivoting plate 42 pivots about the vertical pivoting shaft 42a in response to the pivoting of the wheel support 41 about the horizontal pivoting shaft 41a (see FIG. 10), and the lifting post 20 in the projecting position is returned to the retracted position Let's do it (details will be mentioned later).

  As shown in FIG. 9, the raising and lowering movement stroke S between the protruding position and the retracted position of the raising and lowering column 20 is set to the radius R or less of the caster 10. Specifically, in the case of R = 25 mm and S = 12.5 mm, S = R / 2. As described above, since the elevating movement stroke S is smaller than the radius R of the caster 10 and the inclination (the inclination with respect to the horizontal surface) of the storage rack 2 does not greatly change due to the insertion and removal of the bicycle BCL, the lateral movement of the storage rack 2 is long-term To be done smoothly.

  Next, the detailed structure of the lift post 20 and the foot pedal 30 will be described with reference to FIG. 4 which is a right side view of FIG. 1 and FIG. 5 which is a cross-sectional view thereof. The foot pedal 30 is attached to the storage rack 2 via the pedal attachment frame 31, and the pedal attachment frame 31 is a flat rack fixing portion 311 fixed to the left side wall of the storage rack 2, and the left side from the rack fixing portion 311 And a cylindrical portion 312 which penetrates in the vertical direction.

  The foot pedal 30 is disposed on the left side of the storage rack 2 and pressed by the operator. The upper surface treading portion 301 and the side support portion 302 extending downward from the front edge and the rear edge of the upper surface treading portion 301 in the front and rear direction. And the whole is formed in a portal shape. The side surface support portion 302 is overlapped with the link plate 221 in which the linear connection portion 221a and the expansion portion 221b expanded from the upper end portion of the connection portion 221a toward the storage rack 2 are formed in an L shape, It arrange | positions on the front and back outer side of the cylindrical part 312, respectively. The upper portions of the pair of side surface support portions 302 are fixed to a pedal pivot shaft 32 (for example, a mounting bolt) penetrating the peripheral wall of the cylindrical portion 312 in the front-rear direction. On the other hand, the lower portion of the side surface support portion 302 is connected rotatably relative to the L-shaped middle portion of the link plate 221 (that is, the upper end portion of the connection portion 221a) around the connection shaft 33 (for example, mounting bolt) in the front-rear direction.

  A cylindrical elevating pipe 21 is vertically movably inserted into the cylindrical portion 312 of the pedal mounting frame 31, and an elevating column 20 is inserted and fixed to the lower end of the elevating pipe 21. The lower end portion of the connection portion 221 a in the link plate 221 is fixed to a plate rotation shaft 23 (for example, mounting bolt), and the plate rotation shaft 23 penetrates the circumferential wall of the elevating pipe 21 in the front and rear direction It is inserted in the formed long hole 312b of the up-down direction. Therefore, when the plate rotation shaft 23 moves up and down along the long hole 312, the elevating pipe 21 and the elevating column 20 move up and down integrally with the plate rotation shaft 23. The protruding height of the lifting column 20 with respect to the lifting pipe 21 may be adjustable.

  A pedal tension coil spring 222 (elastic member) is stretched between the pedal pivot shaft 32 and the plate pivot shaft 23, and the pedal tension coil spring 222 is inserted into the cylindrical portion 312 and the elevating pipe 21. An arc-shaped notch groove 312 a is formed on the front and rear outer peripheral surfaces of the cylindrical portion 312 with the pedal pivot shaft 32 as a center and the distance between the pedal pivot shaft 32 and the connecting shaft 33 as a radius. The notch groove 312a is filled with a lubricant such as grease, and the link shaft 33 is lubricated each time the head portion of the connection shaft 33 rushes into the notch groove 312a, so the side support portion 302 of the foot pedal 30 and the link plate The connecting portion 221a can be smoothly rotated relative to the connecting portion 221a over a long period of time.

  As shown in FIG. 7 and FIG. 8, when the operator steps on the upper surface depressing portion 301 and the foot pedal 30 pivots downward about the pedal pivot shaft 32, the connecting shaft 33 is pushed out to the storage rack 2 side. The plate pivot shaft 23 descends along the long hole 312b. As a result, the pedal tension coil spring 222 stretched around the pedal pivot shaft 32 and the plate pivot shaft 23 is extended to generate the maximum deflection (that is, produce the maximum tension load spring force).

  At this time, the connecting shaft 33 (or the connecting portion 221a of the link plate 221) is a straight line VL connecting the pedal rotating shaft 32 and the plate rotating shaft 23 (the cylindrical portion 312, the elevating pipe 21 and the tension coil spring for pedals It is slightly offset from the center line common to 222 and forming a vertical line) on the storage rack 2 side (right side in the figure) (i.e., over the dead point). As a result, the foot pedal 30 is locked in the depressed state, and the lift post 20 is locked in the projecting position. Thus, the link plate 221 and the tension coil spring for pedals 222 constitute a dead point crossing mechanism 22 (holding mechanism) for locking the lifting and lowering post 20 in the protruding position and holding the grounded state. Note that the bulging portion 221 b of the link plate 221 largely protrudes in the space below the storage rack 2 by stepping on the foot pedal 30.

  As shown in FIGS. 9 to 11, when the bicycle BCL is carried into the storage rack 2, the front wheel FW rotates the wheel receiver 41 around the horizontal rotation axis 41 a, and the rotation plate 42 around the vertical rotation axis 42 a It pivots to push back the bulging portion 221 b of the link plate 221. In this way, the lock on the foot pedal 30 in the depressed state by the dead center crossing mechanism 22 (lock at the projecting position of the elevation support 20) is released by carrying in the bicycle BCL, and the elastic force of the pedal tension coil spring 222 (that is, The lifting column 20 returns to the retracted position (standby state) by the pullback force).

(First embodiment)
FIGS. 12 to 14 are explanatory diagrams that further enlarge the main parts of FIGS. 6 to 8 and schematically show the function and structure of the braking plate 6 as the first embodiment.

  The surface of the brake plate 6 is formed as a pressure-contacted portion 6X that is pressed by the end surface 20TX of the end portion 20T of the lift column 20. A plurality of (for example, ten) protruding pieces 6P (protrusions) are formed on the braking plate 6 so as to project upward from the surface 6X, which is a pressure-contacted portion, and these protruding pieces 6P Along a straight line at a predetermined pitch. Specifically, two cuts parallel to the direction (short side direction) orthogonal to the longitudinal direction of the braking plate 6 are made, and press molding is performed from the back side to the front side, and the spaces between the cuts are raised to form a terrace or A projecting piece 6P in the form of a flat roof is formed. At this time, the side surface of each of the protruding pieces 6P forms a convex contact portion 6Y (protruding side surface) in contact with the outer peripheral surface 20TY of the distal end portion 20T of the lifting column 20.

  As shown in FIG. 14, the pitch dimension P of the contact portion 6Y is set larger (P> W) than the maximum lateral width W of the distal end portion 20T of the lift column 20. When the elevating post 20 is in the projecting position, the storage rack 2 is allowed to move in the lateral direction within the pitch dimension P of the contact portion 6Y (see FIGS. 7 and 8). In this embodiment, since the tip 20T is disk-shaped, W is represented by the diameter of the tip 20T, and the pitch dimension P between the adjacent contact portions 6Y and 6Y is the same.

  Therefore, when the lifting post 20 is in the projecting position, the tip 20T (or the storage rack 2) of the lifting post 20 by the action of the external force F (for example, wind power) is equal to P-W (that is, the maximum allowable width of side slip) Since it will contact and stop any one of adjacent convex contact parts 6Y and 6Y (i.e., the side surfaces of the projections) when moved, the carrying-in operation of the bicycle BCL can be performed safely.

  As shown in FIG. 14, the elevating movement stroke S between the protruding position and the retracted position by the elevating column 20 is larger than the height H of the contact portion 6Y (S> H). Therefore, when the elevating post 20 is in the retracted position, the storage rack 2 can slide at high speed (move in the lateral direction) without detouring above the contact portion 6Y (see FIGS. 5 and 11).

  As shown in FIG. 1, the caster 10 is disposed on one end side in the longitudinal direction of the storage rack 2 with respect to the braking plate 6. As described above, since the caster 10 is positioned on the rear end side (the wheel entrance 2 a side) of the storage rack 2 than the braking plate 6, the wheel entrance 2 a receiving weight every time the bicycle BCL is put in and out in the storage rack 2. It contributes to the improvement of strength in the vicinity.

  Next, the operation of the bicycle parking apparatus 1 described above will be described in the order of operation.

<Storage rack empty condition, foot pedal not operated> (Figures 1 to 5)
The storage rack 2 can move laterally along the fixed rail 4 since the elevating post 20 is in the retracted position (standby state) and the caster 10 is in the landing state with the ground surface E.

<Storage rack empty condition, foot pedal operation> (Figures 6 to 8; Figures 12 to 14)
When the tip end surface 20TX of the lifting column 20 presses the pressure receiving portion 6X of the braking plate 6 based on the stepping-in operation of the foot pedal 30, it is displaced to the projecting position (moves into contact with the braking plate 6). The foot pedal 30 is locked in the depressed state by the operation of 22, and the lift post 20 is locked in the projecting position (in contact with the braking plate 6). Since the caster 10 shifts from the landing state to the ground surface E to the floating state, the storage rack 2 stops the lateral movement.

<Foot pedal lock state, external force action> (FIGS. 6 to 8; FIGS. 12 to 14)
When the foot pedal 30 is locked in the step-down state, and the lifting post 20 is in the projecting position and the caster 10 is in the floating state, the tip surface 20TX of the lifting post 20 is A side slip may occur with respect to the welded portion 6X. In this case, the outer peripheral surface 20TY of the lift column 20 comes into contact with the contact portion 6Y of the braking plate 6, whereby the storage rack 2 stops moving in the lateral direction.

<Storage rack actual vehicle condition, foot pedal not operated> (Figures 9 to 11)
When the bicycle BCL is carried in, the operation of the dead point over mechanism 22 which locks the foot pedal 30 in a depressed state (locks the lifting post 20 at the projecting position) is released, and the lifting post 20 retracts by the elastic force of the pedal tension coil spring 222 The position (standby state) is returned to, and the tip end surface 20TX of the lifting column 20 is separated from the pressure-contacted portion 6X. The caster 10 returns to the landing state with the ground surface E, and the storage rack 2 can move laterally along the fixed rail 4.

<Storing rack actual vehicle condition, foot pedal operation> (Figures 9 to 11)
When the foot pedal 30 is depressed in an actual vehicle state, the lift post 20 is once displaced to the projecting position (moves in a state of being in contact with the braking plate 6). However, since the bulging portion 221b of the link plate 221 is blocked by the rotating plate 42, the dead point over mechanism 22 does not operate, and when the depression of the foot pedal 30 is interrupted, the elastic force of the pedal tension coil spring 222 Immediately returns to the retracted position (standby state).

  As described above, since the caster 10 floats and stops the lateral movement of the storage rack 2 without exerting a braking force on the fixed rail 4 or the caster 10, the lateral displacement of the storage rack 2 at the time of carrying in the bicycle BCL is stably prevented. can do. Further, by not using the braking mechanism, the surface deterioration of the fixed rail 4 and the caster 10 can be suppressed and the durability can be improved.

  Specifically, by providing the above-described dead point crossing mechanism 22, the lift post 20 is locked in the projecting position when the foot pedal 30 is operated, so that lateral displacement of the storage rack 2 is ensured when carrying in the bicycle BCL. Can be prevented. In addition, when the bicycle BCL is carried in, the pivot plate 42 of the return mechanism 40 releases the lock by the dead center overpass mechanism 22 and the lift post 20 returns to the retracted position and the caster 10 returns to the landing state with the ground surface E. The storage rack 2 can smoothly move laterally along the fixed rail 4.

  Furthermore, at the time of carrying in the bicycle BCL, for example, the ground surface E gets wet due to rain or the like, and the storage rack 2 is subjected to the action of crosswind, whereby the tip end face 20TX of the lift column 20 is pressure-welded 6X (that is, the braking plate 6). Even when a side slip occurs with respect to the surface), the outer circumferential surface 20TY of the lift column 20 contacts the convex contact portion 6Y (that is, the side surface of the protrusion), and lateral displacement of the storage rack 2 is reliably stopped. Therefore, the safety and workability of the bicycle parking operation can be further improved.

  In addition, the elevating column 20 is disposed in the vicinity of the caster 10, and the elevating column 20 is projected with the caster 10 as a reference (in this case, the caster 10 is in a floating state) and a retracted position (at this time, the caster 10 is Since the lifting and lowering movement stroke S for switching to the landing state can be made small, the downsizing of the lifting and lowering column 20 and, consequently, the entire bicycle parking apparatus 1 can be achieved. Further, by elevating support column 20 and foot pedal 30 being disposed adjacent to entrance 2a, after elevating support column 20 is displaced from the retracted position to the protruding position by operating foot pedal 30, the bicycle BCL is immediately carried in. It is possible to do bicycle parking work well.

  As described above, it is impossible to maintain the caster 10 in the floating state even if the foot pedal 30 is depressed in an actual vehicle state (that is, the depression operation of the foot pedal 30 is substantially impossible). At this time, since the storage rack 2 is movable laterally along the fixed rail 4, parking work can be efficiently performed in an actual vehicle state.

(Modification)
FIGS. 15-17 shows the modification of FIGS. 12-14 (1st Example). In place of the protruding pieces 6P, rising pieces 6P '(protrusions) are formed to project upward on the surface 6X (pressure-contacted portion) of the braking plate 6 in this modification. Specifically, a cut is made in three U-shaped three sides (i.e., three sides out of four sides forming a rectangle) in braking plate 6, and the other side is a direction orthogonal to the longitudinal direction of braking plate 6 (short By placing it in the hand direction and pressing it as a bending line, the portion surrounded by the three side cuts is erected at right angles around the bending line, and a rectangular standing piece 6P 'is formed to protrude. At this time, the side surface of each upright piece 6P ′ forms a convex contact portion 6Y (protruding side surface) that comes in contact with the outer peripheral surface 20TY of the tip 20T of the elevation column 20. The function of the upright piece 6P 'is substantially the same as that of the raised piece 6P described above, and thus the detailed description will be omitted.

(Other modifications)
FIGS. 18 to 20 show other modified examples of FIGS. 12 to 14 (first embodiment). A fixed piece 6P '' (protrusion) is formed to project upward on the surface 6X (pressure-contacted portion) of the braking plate 6 in this modification instead of the protruding piece 6P. Specifically, a strip-shaped fixed piece Fixing piece 6P ′ ′ is mounted on surface 6X (pressure-welded part) of braking plate 6 so that the longitudinal direction of 6P ′ ′ coincides with the direction (short direction) orthogonal to the longitudinal direction of braking plate 6 By welding the short sides of 6P ′ ′, strip-like fixing pieces 6P ′ ′ are formed so as to protrude. At this time, the side surfaces of the respective fixing pieces 6P ′ ′ are in contact with the outer peripheral surface 20TY of the tip 20T of the elevating column 20. A convex contact portion 6Y (protruding side surface) is formed. The function of the fixed piece 6P ′ ′ is substantially the same as that of the raised piece 6P described above, and thus the detailed description is omitted.

Second Embodiment
21 to 23 schematically illustrate the function and structure of a brake plate 106 according to a second embodiment, instead of the brake plate 6 according to the first embodiment (FIGS. 12 to 14).

  A plurality of (for example, ten) through holes 106 H are formed in the braking plate 106 (plate-like member) so as to be aligned in a straight line along the lateral direction which is the longitudinal direction of the braking plate 106. Each of the through holes 106H has a size that allows the tip end portion 20T of the lifting column 20 (lifting body) to pass. Therefore, the inner circumferential surface of each through hole 106H constitutes a concave contact portion 106Y (a through hole inner circumferential surface) that comes in contact with the outer circumferential surface 20TY of the distal end portion 20T of the lifting column 20. In the present embodiment, the pressure-contacted portion 106X pressed by the front end surface 20TX of the front end portion 20T of the lifting column 20 is the ground surface E located immediately below the through hole 106H.

  As shown in FIG. 23, the minimum lateral width D of the contact portion 106Y (the inner circumferential surface of the through hole) formed on the braking plate 106 is larger than the maximum lateral width W of the tip 20T of the lifting column 20 (D> W). It is set. When the lifting post 20 is in the projecting position, the storage rack 2 is allowed to move laterally within the minimum width D area of the abutment portion 106Y. In this embodiment, D is represented by the diameter of the through hole 106H because the contact portion 106Y is the inner peripheral surface of the circular hole, and W is represented by the diameter of the tip portion 20T because the tip 20T is disk-shaped. Be The through holes 106H have the same diameter.

  Therefore, when the lifting post 20 is in the projecting position, the tip 20T (or the storage rack 2) of the lifting post 20 by the action of the external force F (for example, wind power) is as much as D-W (that is, the maximum allowable width of side slip) Since it will contact and stop somewhere on concave contact part 106Y (that is, the inner peripheral surface of a through-hole) if it moves, the carrying-in operation of bicycle BCL can be performed safely.

  As shown in FIG. 23, the elevating movement stroke S between the projecting position and the retracted position by the elevating column 20 is larger than the height H of the contact portion 106Y (corresponding to the thickness of the braking plate 106 in this embodiment) S> H). Therefore, when the elevating post 20 is in the retracted position, the storage rack 2 can slide at high speed (lateral movement) without detouring above the contact portion 106Y.

  As described above, when the bicycle BCL is carried in, for example, the ground surface E gets wet due to rain or the like, and the storage rack 2 receives the action of the crosswind, whereby the tip end surface 20TX of the lifting column 20 is pressed against the pressure receiving portion 106X (that is, the ground Even when a side slip occurs with respect to the surface), the outer circumferential surface 20TY of the lift column 20 contacts the concave contact portion 106Y (that is, the inner circumferential surface of the through hole), and lateral displacement of the storage rack 2 reliably stops. As a result, the safety and operability of the bicycle parking operation can be further improved.

(Modification)
24 to 26 show modified examples of FIGS. 21 to 23 (second embodiment). The braking plate 106 (plate-like member) in this modification is indirectly fixedly arranged on the ground surface E via the base plate 107 (intermediate plate material). The base plate 107 has the same shape, the same size, and the same thickness as the braking plate 106, but no through holes are formed. Therefore, in this modification, the pressed portion 106X ′ pressed by the tip surface 20TX of the tip portion 20T of the elevating column 20 (lifting body) is the upper surface of the base plate 107 located directly below the through hole 106H.

  In the second embodiment (FIGS. 21 to 23) and various modifications (FIGS. 15 to 17, 18 to 20, 24 to 26), the first embodiment (FIGS. 12 to 14) and The parts having the same functions are given the same reference numerals and the detailed description is omitted. Moreover, each Example and each modification which were demonstrated above can be implemented combining suitably in the range which technical contradiction does not produce.

  The present invention is not limited to the outdoor bicycle parking lot always installed on the sidewalk, in the park, etc., the indoor bicycle parking lot opened in an apartment or apartment, or the underground bicycle parking lot annexed to a building or underground station etc. It is applicable also to a bicycle parking apparatus. In addition, it is applicable also to the lower end bicycle storage device in the upper and lower two-stage type bicycle parking machine.
