Description

  The present invention relates to a two-stage bicycle parking apparatus that can store a bicycle in two stages, upper and lower storage sections, and more specifically, a two-stage bicycle parking apparatus in which the upper storage section is configured to be movable up and down. Relates to the device.

  A two-stage bicycle parking device that can store bicycles in two stages, upper and lower storage units, can store a large number of bicycles in a small space. Widely used.

  In the two-stage bicycle parking apparatus, the upper storage portion is at a high position, and a bicycle cannot be placed on the upper storage portion as it is. For this reason, usually, when storing a bicycle, the upper storage section is lowered to a low position, and after storing the bicycle, an elevating means that can raise the upper storage section to a high position is provided.

The two-stage bicycle parking device described in Patent Document 1 includes a constant load device (constant load spring) that applies a traction force that balances the weight of the rack to the bicycle rack at the upper end as a lifting means. .
However, the lifting means using such a constant load device (constant load spring) has problems that it is difficult to change the set load and that maintenance such as repair and adjustment is not easy.
Moreover, since the installation space for providing two constant load apparatuses is required, there also existed a problem that a bicycle parking apparatus enlarged.
Furthermore, since the bicycle is pushed forward by the bicycle, the lock device is unlocked and the bicycle rack (bicycle mounting table) is automatically raised by the pulling force of the spring. Even when not, there is a risk that the treadle is pushed downward and the bicycle rack rises, which is dangerous.

On the other hand, in Patent Document 2, a balancer container filled with liquid is used as a weight, and the balancer container and a lifting platform (bicycle mounting table) are connected by a wire to move the lifting platform up and down. A bicycle parking system is described.
However, this device has a structure in which the wire and the carriage of the lifting platform (bicycle mounting table) are exposed to the outside, and the wire extends over a long distance toward the rear of the lifting platform, There was a problem that failure was likely to occur. That is, since the bicycle parking device is often used outdoors, there is a risk that foreign matter such as earth and sand, dust, and fallen leaves may be caught by a wire or a cart or may be damaged due to external factors such as mischief. .
In addition, since the lifting platform (bicycle mounting table) is suspended by a wire in the center, it is difficult to balance the front and rear, and a large load is applied to the carriage of the lifting platform, which can hinder travel or break. There was also a problem of fear.
Furthermore, since the balance of weight with the lifting platform (bicycle mounting table) is balanced by a single balancer container containing liquid, there is a problem that balance adjustment is difficult and unstable.
Moreover, since it is necessary to operate the switch to raise the lifting platform (bicycle mounting table), it is troublesome, and there is a risk that the lifting platform may be raised by operating the switch by mistake, which is dangerous. There was also a problem.

8A and 8B are diagrams showing the urging means 44, wherein FIG. 8A is a front view, FIG. 8B is a side view, and FIG.
The biasing means (44) comprises a torsion coil spring as shown in the figure.
In the urging means (44) (torsion coil spring), a pin (46) serving as a rotation fulcrum of the movable stopper (43) is inserted into the coil portion (441). Further, the upper part (442) of the coil part (441) is locked above the bent part of the movable stopper (43), and the lower part (443) of the coil part (441) is the front plate (212) of the main body (21). The rear surface is locked (see FIG. 8C).
Thus, the urging means (44) is attached so that the movable stopper (43) rotates in one direction (the clockwise direction in FIG. 8C) with the pin (46) inserted through the bent portion as a fulcrum. It is fast. In the direction (one direction) in which the movable stopper (43) is urged, the stopper pin (42) attached to the lower end (one end) of the movable stopper (43) is inserted into the through hole (411) of the stopper fixing plate (41). ).

Next, the operation of the fixing means (4) will be described with reference to FIG.
As shown in FIG. 9A, when the front wheel (F) of the bicycle is not in contact with the connecting pin (45) that connects the upper end of the movable stopper (43), the movable stopper is driven by the biasing force of the biasing means (44). (43) is biased in the one direction (FIG. 9 (a) clockwise direction), thereby maintaining the state where the stopper pin (42) is inserted into the through hole (411) of the stopper fixing plate (41). ing. Therefore, although the raising / lowering body (2) is applied with an upward tensile force by the weight (32), it is fixed at the lower position without rising, and the bicycle mounting table (5) also remains at the lower position.

  As shown in FIG. 9B, when the bicycle advances and the front wheel (F) pushes the connecting pin (45) that connects the upper end of the movable stopper (43), the movable stopper (43) is urged ( 44) against the urging force of 44), the stopper pin (42) is rotated in the through hole (411) of the stopper fixing plate (41). ) Then, the elevating body (2) is raised by the upward tensile force by the weight (32), and the bicycle mounting table (5) is also raised accordingly.

As described above, since the fixing of the elevating body (2) by the fixing means is not released unless the front wheel (F) of the bicycle pushes the connecting pin (45) that connects the upper end of the movable stopper (43), the bicycle When not stored, the elevating body (2) and the bicycle mounting table (5) do not rise and are safe.
Further, when the bicycle is stored, the fixing means is released by pushing the connecting pin (45) with the front wheel (F) of the bicycle, and the elevating body (2) and the bicycle mounting table (5) are raised. As a result, the bicycle mounting table (5) can be automatically raised only by moving the bicycle forward without requiring any special operation, and there is no troublesome operation. Moreover, unless the bicycle is advanced until the front wheel (F) pushes the connecting pin (45), the fixing by the fixing means is not released, so that the bicycle mounting table (5) may be raised without the bicycle being completely mounted. Not very safe.

  Further, since the stopper fixing plate (41) has a plurality of pairs of through holes (411) spaced apart in the vertical direction, the stopper pin (42) is inserted in the fixing state shown in FIG. 9 (a). By changing the height of the through hole (411), the height at which the bicycle mounting table (5) is fixed can be changed. Therefore, it becomes possible to deal with bicycles of various sizes and types. Further, if the stopper pin (42) is inserted into any of the plurality of through holes (411) arranged in the vertical direction, the bicycle mounting table (5) is fixed, so that it can be easily fixed. There is little risk of fixing failure and it is safe.

The bicycle mounting table (5) is a table having a concave section for mounting a bicycle, and has a width and a length capable of mounting a front wheel and a rear wheel of the bicycle.
The front end of the bicycle mounting table (5) is attached to the lifting body (2), and as a result, the bicycle mounting table (5) moves up and down together with the lifting body (2).
On the lower surface of the bicycle mounting table (5), a grip portion (51) is provided that serves as a handle when the bicycle mounting table (5) in the raised position is pulled down by human power.

The accommodating means (6) is formed in the slit (11) (in the column (1)) by rotating the bicycle mounting table (5) upward with the mounting portion (211c) to the lifting body (2) as a fulcrum. It is a means for accommodating.
The accommodating means (6) includes a pair of left and right connecting rods (61) and a fluid pressure cylinder (62).

The connecting rod (61) is a rod having a bendable portion (611) in the middle in the length direction (see FIG. 3 (a)), and the bendable portion (611) is formed of a chain or the like.
One end of the connecting rod (61) is rotatably attached to the side plate (211) of the main body (21) of the elevating body (2). Specifically, the side plate (211) is rotatably attached to a hole (211b) provided in an upper part from the attachment part (211c) of the bicycle mounting table (5).
The other end of the connecting rod (61) is attached so as to be rotatable with respect to the middle part in the length direction of the bicycle mounting table (5).
Accordingly, the connecting rod (61) connects the lifting body (2) and the bicycle mounting table (5) so as to be inclined downward from the front to the rear (see FIGS. 1 and 3A). ).

The fluid pressure cylinder (62) is composed of a gas cylinder, a hydraulic cylinder or the like, and is disposed so that the rod (621) expands and contracts in a substantially vertical direction.
The base end portion of the fluid pressure cylinder (62) is rotatably attached to the front plate (212) of the main body (21) of the elevating body (2). Specifically, a pair of left and right mounting plates (212c) at a position above the mounting portion (211c) of the bicycle mount (5) of the main body (21) and in the vicinity of one end of the connecting rod (61). Is attached to.
The distal end portion (the distal end portion of the rod (621)) of the fluid pressure cylinder (62) is rotatably attached to the bicycle mounting table (5) via the extending member (63). Specifically, the bicycle mounting base (5) has a front end portion slightly ahead of the attachment portion (211c) with respect to the main body (21), and an extending member (63) extending upward from the front end portion. It is attached (see FIG. 3 (a)).

FIG. 10 is a view showing the extending member (63), where (a) is a side view and (b) is a front view.
The extending member (63) is bent in an L shape when viewed from the side and has a pair of left and right side plates (631) each having a through hole (631a) at one end and a pair of left and right side plates (631). 631) and a cylindrical portion (632) provided at the other end.
A pin (64) is inserted through the cylindrical portion (632) (see FIGS. 3A and 3B). This pin (64) is also inserted into the hole (211c) of the side plate (211) of the elevating body (2) and the bicycle mounting table (5), and when the bicycle mounting table (5) is rotated upward. This is the pivot point of
A pin (65) is inserted through the through hole (631a) of the extending member (63) (see FIG. 3 (a)). The pin (65) is inserted into a hole provided in the tip of the fluid pressure cylinder (62) (the tip of the rod (621)), and is connected to the extension member (63) and the fluid pressure cylinder (62). The tip of the rod (621) is connected.

Next, the operation of the housing means (6) will be described with reference to FIG. 11 in the order of (a) to (g).
In the initial state of FIG. 11A, the bicycle mounting table (5) is in a horizontal state.
In this state, a force for shortening the rod (621) is acting on the fluid pressure cylinder (62), and the extending member (63) is pulled upward. Thereby, although the force which tries to rotate below acts on a bicycle mounting base (5), it is prevented from rotating below from a horizontal state by a connection rod (61).

From the state of FIG. 10 (a), when the user holds the rear part of the bicycle mounting table (5) in a state in which no bicycle is mounted and pushes it upward, the bicycle mounting table (5) is lifted by the lifting body (2). The pin (64) of the attachment portion (211c) to the main body (21) is rotated upward with the fulcrum as a fulcrum.
As the bicycle mounting base (5) rotates upward, the rod (621) of the fluid pressure cylinder (62) extends and the bending angle of the bendable portion (611) of the connecting rod (61) increases. Accordingly, the angle of the bicycle mounting table (5) with respect to the floor surface also increases (see FIGS. 10B to 10F).
And if a bicycle mounting base (5) rotates 90 degree | times upward, a bicycle mounting base (5) will be in the state accommodated in the slit (11) (inside the support | pillar (1)).

  Thus, by accommodating the bicycle mounting table (5) in the slit (11) and storing it in the support column (1), the bicycle parking apparatus can be made very compact when not in use or transported. Further, when the bicycle mounting table (5) is rotated upward, a resistance force is applied by the fluid pressure cylinder (62), so that the bicycle mounting table (5) may rotate carelessly during use. Prevented and safe. Moreover, it can prevent reliably that a bicycle mounting base (5) rotates below a reference | standard position (horizontal position) with a connection rod (61).

In the two-stage bicycle parking apparatus according to the present invention, a plurality of upper storage sections are installed side by side in the width direction as in the conventional two-stage bicycle parking apparatus (for example, see Patent Documents 1 and 2 above). A lower storage part (not shown) is provided below.
The configuration of the lower storage portion is not particularly limited. For example, the applicant of the present application discloses the bicycle mounting table disclosed in Japanese Patent Application Laid-Open Nos. 2008-296784, 2004-256110, and Utility Model Registration No. 3045190 in the lateral direction. A sliding bicycle storage device that can slide is preferably used.
When a sliding bicycle storage device is used as the lower storage unit, when the bicycle mounting table (5) in the upper storage unit is lowered, the bicycle mounting table in the lower storage unit below it is slid horizontally to move. By doing so, the bicycle mounting table in the lower storage section does not obstruct the lowering.

  The two-stage bicycle parking apparatus according to the present invention is suitably used in a place where it is necessary to park a large number of bicycles in a narrow space such as an apartment house or a bicycle parking lot of a station.
