Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a two-tiered bicycle parking device, more specifically, a two-tiered bicycle parking device, more specifically, a device for parking bicycles in two tiers, an upper tier and an upper tier. This invention relates to a bicycle parking device that can be pulled out and taken out at will.

As a conventional two-stage bicycle parking device of this kind,
For example, as shown in Figure 8, a support stand 6d for mounting a bicycle can be slid back and forth on a fixed frame 1d fixed to a support post 3d and provided horizontally so as to divide two upper and lower parking spaces. and fixed frame body 1
It is rotatably mounted on the rear end side of d, and its support stand 6
By the rotation of d, the rear end of the support base 6d is placed on the ground 2.
A device has already been developed that allows the bicycle to be put in and taken out by tilting it so that it can be placed on the bicycle.

However, since this bicycle parking device is configured to slide and rotate the support base 6d via the wire 29 by the elastic force of the spring 28,
After the support stand 6d is rotated and tilted and the bicycle is taken out from the support stand 6d, the tensile force of the spring 28 increases rapidly as the load applied to the support stand 6d decreases, so that the bicycle is not tilted. There was a serious drawback in that when the empty support stand 6d was rotated in the opposite direction and stored again in the fixed frame 1d, the support stand 6d suddenly jumped up, creating a danger. . In addition, since the tensile force of the spring 28 increases rapidly, the user has to
There is even a risk that the support stand 6d, which has been tilted before being held and stored in the fixed frame 1d, will spring up by itself, and in such a case, the user may be distracted by, for example, the bicycle he has taken out. There was a risk that an unexpected accident could occur.

That is, in the bicycle parking device as described above, the tensile force of the spring 28, which is a force applying means when rotating the support stand 6d, is determined by the magnitude of the load applied to the support stand 6d, that is, when the bicycle is stored in the support stand. The above-mentioned problem was caused by the large and sudden change depending on whether the person was present or not.

In order to solve all of these problems, the present invention aims to make the force applied when rotating the support stand approximately constant regardless of whether a bicycle is stored in the support stand. An object of the present invention is to provide a completely new and useful two-stage bicycle parking device that allows a support stand to be moved in and out of a fixed frame extremely smoothly and safely.

The present invention is configured to achieve the above-mentioned object, and includes a support base for mounting a bicycle that can be slid back and forth with respect to a fixed frame and can be rotated on the rear end side of the fixed frame. In the two-stage bicycle parking device provided in An upper fulcrum roller and a lower fulcrum roller are disposed above and below the clamping surface of the support base so as to form a fulcrum of movement, and a telescoping mechanism for applying a substantially constant force in the rotating direction of the support base. The main point is that it has been established. In other words, since a telescoping mechanism is provided to apply a substantially constant force in the direction of rotation of the support base, the operation of rotating the support base and pulling it out from the fixed frame and storing it can be done very smoothly. Not only can this be done, but the support base can be rotated with a substantially constant pushing or pulling force regardless of the magnitude of the load directly applied to the support base, that is, regardless of whether a bicycle is stored in the support base or not. This allows the bicycle to be taken in and out of the support stand.

In this way, the present invention is provided with an extensible mechanism that can rotate the support base with a substantially constant pushing force or tensile force regardless of whether or not a bicycle is stored in the support base. Even after rotating the bicycle to tilt it and taking the bicycle out of the support stand, there is no sudden tensile force acting on the support stand as in the conventional case, and therefore, it is easy to rotate the empty support stand. Even when the bicycle is moved and stored in the fixed frame, the support stand does not suddenly jump up, and of course the support stand does not spring up automatically immediately after the bicycle is taken out, making it the most dangerous bicycle in the past. This has resulted in a particularly remarkable effect in that the work of storing the empty support stand into the fixed frame can be carried out extremely safely.

Moreover, since the support base can be rotated with approximately constant extrusion force and tension, it is possible not only to store the empty support base in the fixed frame, but also to carry out work to take the support base into and out of the fixed frame. There is an advantage that all of these operations can be performed very smoothly and safely by always rotating the support base with a substantially constant force.

Furthermore, the upper fulcrum roller and the lower fulcrum roller are arranged above and below the clamping surface of the support base so that when the support base is rotated, they can form a fulcrum for the rotation while being clamped from above and below. There is an advantage that the table can be rotated very smoothly and reliably.

Moreover, the presence of the upper fulcrum roller has the advantage that rotation at an inadvertent position, such as when the support base is not fully slid to the rear side of the fixed frame, is reliably inhibited.

The figure shows an enlarged sectional view taken along the line CC in FIG. 2.

1 to 3, reference numeral 1 indicates a front end 1a of a support 3 vertically disposed on the ground 2 to form an upper parking area A of two upper and lower parking areas A and B.
It is a fixed frame with a roughly U-shaped cross section and a rail-like frame that is fixed horizontally and has an upward L on the upper end of the entire frame.
A letter-shaped bent portion 4 is formed, and there is no such bent portion 4 near the rear end portion 1b, and the upper end is formed low, and the outer peripheral surface thereof has a substantially U-shaped portion that is thicker than the fixed frame 1. A reinforcing plate 5 of the shape is fixed.

With the upper fulcrum roller rotatably attached to 2,
The upper surface of the bending part 8 at the upper end of the support stand 6 can be rolled, and when the support stand 6 rotates and tilts and the tapered surface 23 formed on the rear end 6b side contacts the ground, it is simultaneously supported. The table 6 is arranged so as to prohibit further rotation of the front end 6a side. A lower fulcrum roller 13 is rotatably provided on a shaft 14 fixed to the reinforcing plate 5, and is movable on the lower surface of the bent portion 8 and displaced back and forth with respect to the upper fulcrum roller 11. It is provided.

And like this, the upper fulcrum and lower fulcrum roller 1
1 and 13 roll on the upper and lower surfaces of the bent portion 8, respectively, while holding the bent portion 8 at the upper end of the support base 6, and as described above, the wheels 9 provided on the lower surface side of the support base 6 are attached to the fixed frame. By rolling the bottom surface 1c of the support base 6, the support base 6 is configured to be slidable back and forth with respect to the fixed frame body 1.

15 is a gas spring for swinging the rocking plate 10, one end 15a is rotatably attached to the fixed frame 1, and the other end has a rod 16.
is provided so as to be able to rise and fall freely, and the tip portion 16a of the rod 16 is attached to the wing portion 10b at one end of the swing plate 10. As shown in FIG. 4, this gas spring 15 is filled with high-pressure gas to maintain a substantially constant output.

Reference numeral 25 denotes a stopper that can be engaged with the stopper 24 provided on the lower surface of the support base 6, and is erected on the bottom surface 1c of the fixed frame 1 on the rear end 1b side. 26
is a stopper for preventing the support base 6 from protruding toward the front end 1a side of the fixed frame 1, and is attached to the lower surface of the support base 6 at a relatively rear side so that it can be locked to the stopper 25. .

Reference numeral 17 denotes a swing roller pivotally attached to the other end wing portion 10c of the swing plate 10, and is rotatably provided on the lower surface of the bending portion 8 at the upper end of the support base 6. Reference numeral 18 denotes a substantially L-shaped retaining lever that can be engaged with the tip 19a of a locking rod 19 provided coaxially with the swinging roller 17. By engaging with the tip end 19a of the support base 6, sliding with respect to the fixed frame 1 is prohibited. Reference numerals 20 and 21 denote a front wheel frame and a rear wheel frame provided at the front end and rear part of the support base 6;
Reference numeral 2 denotes a handle erected at the rear end of the support base 6.

The above configuration only describes the configuration of the upper parking section A of the two-tier bicycle parking device, and the detailed explanation of the configuration of the lower parking section B is omitted because it is the same as before. do.

Next, a case will be described in which a bicycle placed in the upper parking section is taken in and out of the bicycle parking device having the above-described configuration.

First, rotate the locking lever 18 and lock the locking rod 19.
When the handle 22 is grasped and the support base 6 is pulled in the direction of arrow A in FIG. The support base 6 rolls to the rear end 1b of the fixed frame 1 as shown in FIG.
be slid to the side. In this case, since the bent portion 8 of the support base 6 is held between the upper and lower support rollers 11 and 13, the support base 6 is reliably guided, and the presence of the upper support roller 11 prevents it from being placed in an unexpected position. The support stand 6 never rotates.

Next, when the support base 6 is slid in this way until the front end 6a of the support base 6 approaches the rear end 1b of the fixed frame 1, and the support base 6 is pushed down, the support base 6 is pushed down. It rotates in the direction of arrow B in Figure 6 due to the lowering force and its own weight. At this time, the swinging roller 17 that is in contact with the lower surface of the bent portion 8 of the support base 6 is pushed down, and the swinging plate 10 with the other end wing portion 10b coaxially fixed to the swinging roller 17 is swung in the direction of arrow C in FIG. It happens. In this case, the gas spring 15 is filled with high-pressure gas to keep the output substantially constant, so the return movement of the rod 16 is performed with a substantially constant force, and therefore the swinging plate 10 is oscillated. The movement, and thus the rotation of the support base 6, can be carried out very smoothly with a substantially constant force. Then, the support base 6
At the same time as the support base 6 is rotated, the bent portion 8 near the front end 6a of the support base 6 is locked to the upper fulcrum roller 11, so that further rotation of the support base 6 is completely prohibited. Become. Moreover, in this case, the stopper 24 provided on the lower surface of the front end 6a side of the support base 6 is engaged with the stopper 25 provided upright on the bottom surface of the rear end 1b side of the fixed frame 1, so that the support base 6 This will completely prevent it from coming off the fixed frame 1. Therefore, the support stand 6 is positioned at a predetermined tilt angle, and the bicycle 7 can then be easily taken out from the support stand 6 by removing the front wheel frame 20 and the rear wheel frame 21 from the bicycle wheels. be.

When the bicycle 7 is taken out in this way and the empty support stand 6 is to be stored again in the fixed frame 1, the support stand 6 is first lifted and rotated in the opposite direction to that used when taking it out. Then, the pressing force of the bent portion 8 of the support base 6 against the swinging roller 17 is relaxed, and the rod 16 of the gas spring 15, which had been contracted due to the relaxation of this pressing force, is urged by the high pressure gas. The support table 6 is moved in the opposite direction to the case of taking out the support table 6, and accordingly, the swing plate 10 swings in the opposite direction and the swing roller 17 comes into contact with the lower surface of the bent portion 8 of the support table 6. However, he was lifted up.

In this case, the weight of the support stand 6 has already been significantly reduced since the bicycle 7 has been taken out, but the rotation operation for storing the support stand 6 into the fixed frame 1 has an approximately constant output. The forward movement of the rod 16 of the gas spring 15 causes the bicycle 7 to be removed with approximately the same and approximately constant force as when the support base 6 is rotated.

Therefore, even though the load directly applied to the support base 6 is significantly reduced, the support base 6 can be rotated extremely safely and smoothly without suddenly jumping up.

After the support stand 6 has been rotated until it becomes approximately horizontal, the empty support stand 6 can be stored in the fixed frame body 1 by sliding the support stand 6 toward the front of the fixed frame body 1. It will become. In this case, the stopper 26 provided at the rear of the support base 6 is locked with the stopper 25 of the fixed frame 1, and further sliding of the support base 6 is prohibited. It is housed within the fixed frame 1 without protruding from the frame 1. Moreover, after the support base 6 is stored in this way, the rear end of the fixed frame 1 of the support base 6 is fixed by engaging the retaining lever 18 with the tip 19a of the locking rod 19. 1b
This also completely prevents falling from.

Next, when storing the removed bicycle 7 in the support stand 6 again, use the same operation as described above to slide and rotate the empty support stand 6, pull it out from the fixed frame 1, and tilt the bicycle 7. The bicycle 7 is placed on the support stand 6, and then by rotating and sliding in the opposite direction, the support stand 6 housing the bicycle 7 can be stored again in the fixed frame 1. Even in this case, the presence of the gas spring 15 with a substantially constant output allows the support base 6 to be rotated extremely safely and smoothly with a substantially constant force.

As described above, in the above embodiment, the support base 6 can be rotated with a substantially constant force by the expansion and contraction of the gas spring 15 with a substantially constant output, so that the support base 6 can be moved into the fixed frame 1. The loading operation can be carried out very safely and smoothly, and especially when storing the empty support stand 6 in the fixed frame 1, which was the most dangerous task in the past, the support stand 6 can be prevented from suddenly jumping up. This has resulted in a particularly remarkable effect in that the danger can be almost completely eliminated.

Incidentally, in the above embodiment, the swing plate 10 is formed into a substantially sector-shaped shape, but its shape is not limited at all, and it may be formed into a dogleg shape, for example, as shown in FIG.

Further, in this embodiment, the output of the gas spring 15 is transmitted to the support base 6 via the swing plate 10 and the swing roller 17, but the swing plate 10 and the swing roller 17 are It is by no means essential to the invention.

The means for applying force for rotating the support base 6 is by no means limited to the gas spring 15 of this embodiment, and for example, a clockwork spring may also be used. In short, regardless of the magnitude of the load applied to the support base 6, that is, regardless of whether or not the bicycle 7 is stored in the support base 6, the support base 6 is always rotated with a substantially constant pulling force or pushing force. It is sufficient if an expansion/contraction mechanism is provided as a means for applying force to move the object.

Furthermore, the positions of the upper fulcrum and lower fulcrum rollers 11 and 13 do not matter at all; the point is that they are shifted back and forth so that a part of the support base 6 is sandwiched between the upper and lower portions to form a fulcrum for the rotation of the support base 6. It is sufficient if the

Furthermore, the shapes of the support base 6 and the fixed frame 1 are not limited to those in the embodiment, and their shapes are not limited at all.

Furthermore, since the reinforcing plate 5 was provided in this embodiment, the effect of reinforcing the fixed frame 1 when the support base 6 was rotated was good, and a favorable effect was obtained in that the fixed frame 1 could be prevented from being damaged due to long-term use. , this reinforcing plate 5 is by no means essential to the present invention.

Further, in this embodiment, stoppers 24 and 26 are provided before and after the support base 6, and the stoppers 24 and 26 are provided on the fixed frame 1.
5, a favorable effect was obtained in that the engagement between these stoppers 24 and 26 and the stopper 25 can almost completely prevent the support base 6 from protruding or falling from the fixed frame 1. , 25, and 26 are also by no means essential to the present invention.

All other design changes may be made within the intended scope of the present invention.
