7 and the front wheel J ₁ and rear wheel of bicycle J, respectively.
A front wheel locking member 1 is integrally fixed to the front and rear portions of the horizontal protrusions 16a and 16b in order to prevent the wheel from falling and to act as a stopper when the _J2 is inserted.
8, a rear wheel locking member 18', and a handle 19 projecting from the rear end plate 16c of the parking frame 16.

Therefore, the parking member 15 has both support plates 7 in the fixed frame 5 and in the support guide member 6,
7', and the horizontal protrusion 16
A and 16b are respectively supported by a pair of front and rear support rollers 2 on the front and rear sides of the upper inner surfaces of support plates 7 and 7'.
0, 20, 21, 21; 20', 20', 21',
21' and supported by the support plate 7,
A pair of guide rollers 22, 23, 22', and 23' pivotally supported at the front and rear of the central inner surface of the parking frame 16 are brought into abutment engagement with the left and right vertical outer surfaces of the parking frame 16, thereby forming the parking member 15. Prevents shaking from side to side. Further, the parking member 15 has a pair of left and right support rollers 24, 24' pivotally supported slightly rearward from the center of the fixed frame 5, which are brought into contact with the lower surfaces of the horizontal protrusions 16a, 16b to provide auxiliary support. We are providing support.

Reference numeral 25 denotes a rope for lifting and lowering the parking member 15, one end of which is fixed to the lower left end of the rear end plate 16c of the parking frame 16, and a relay pulley 26 which is pivotally supported inside the left side support plate 7 of the support guide member 6. an upper groove, a lower groove of a relay pulley 27 pivoted on the central bottom of the fixed frame 5, and a fixed pulley group 28 pivoted on the front bottom of the fixed frame 5;
An upper pulley 28a, a movable pulley 30 pivotally supported between upper and lower mounting plates 29a and 29b at the rear of the fixed pulley group 28, a lower pulley 28b of the fixed pulley group 28, and the other end attached to both mounting plates. It is fixed to a pin 31 fixed between the front parts of 29a and 29b.

32 are two pins 33, 33 fixed between the rear parts of both the mounting plates 29a, 29b and the support shaft 10.
By constantly biasing the movable pulley 30 rearward with two tension springs stretched between the movable pulley 30 and the like, the parking member 15 is pulled forward via the rope 25, the fixed pulley group 28, and the like.

A rear stopper plate 34 is fixed to the rear lower surface of the parking frame 16, and the rear ends of the support plates 7, 7' abut against each other to prevent the parking member 15 from moving further forward. Reference numeral 35 denotes a front stopper plate attached between the upper surfaces of the horizontal protrusions 16a and 16b at the front end of the parking frame 16, which collides with the front ends of the support plates 7 and 7' to prevent the parking member 15 from being pulled any further. This prevents the vehicle from descending and retreating.

Reference numeral 36 denotes a lock mechanism for preventing the parking member 15 from moving backward in the parking state in the upper parking space. The locking mechanism 36 includes a protruding member 37 projecting from the rear upper inner surface of the right support plate 7' and a downwardly inclined protruding member 37, and a rear intermediate portion (located rearward from the center of gravity) located on the right side of the parking frame 16. A latch member 39 is pivotally supported on the rear end of the horizontal protrusion 16b via a bracket 38 so as to be swingable in the vertical direction, extends in the front-rear direction, has a front end bent downward at right angles, and a rear end bent slightly upward. It is completed.

Further, the latch member 39 is connected to the projection member 3.
7, the lower surface slightly forward of the pivot point is in the U-shaped notch 3 of the bracket 38.
It abuts against the lower surface of 8a due to its own weight to maintain a horizontal state as a whole.

Furthermore, the locking mechanism 36 is in a state in which the parking member 15 has been fully loaded, as shown by the solid line in FIG. 10 (at this time, the stopper plate 34 is
Even when the latch member 3 is in contact with the rear end)
The stopper plate 34, the protrusion member 37, and the latch member are arranged in such a way that a slight gap S is provided between the front end of the protrusion member 37 and the vertical bent portion 39a of the latch member 39 in order to freely swing the stopper plate 34, the protrusion member 37, and the latch member 9. The mounting position relationship of 39 is determined.

Accordingly, when the parking member 15 is pulled back forward from the state shown by the three-dot chain line in FIG. It rises while colliding with the slope 37a of the member 37 (10th
When it reaches the top of the slope 37a (two-dot chain line in the figure), it separates from the protruding member 37 and falls under its own weight, becoming locked as shown by the solid line in FIG. 10, thereby substantially preventing the parking member 15 from moving backward.

In addition, to release the locked state, since the gap S is provided, the lower end of the vertically bent portion 39a is moved upwardly from the protruding member 37 by simply lowering the rear end of the latch member 39 downward with a finger (see Fig. 10). (dotted chain line), the parking member 15 may be moved rearward in this state.

Reference numerals 40 and 40' indicate two types of locking members, low and high, for the front wheel J ₁ for parking the bicycle J directly on the ground floor 3 of the lower parking space D, and the wheel fitting frame 4 has a U-shaped cross section.
0a, 40′a, the former is horizontal side 2a
The horizontal side 2a is
The latter is an angle member 4 that connects the vertical side and the horizontal side 2'a of the support 2'.
1', it is fixed in a slope parallel to the horizontal side 2'a and slightly upwardly forward, and furthermore, anti-falling/stopping devices 40b and 40'b are provided at the top, respectively.

In use, first, as shown in FIG. 2, the parking member 15 is housed horizontally within the fixed frame 5 (at this time, if the position of the support shaft 10 is Xo in FIG. , 14' cardinal point is
Therefore, the support guide member 6 receives a counterclockwise moment (=f×d ₁ ) about the support shaft ₁₀ as a fulcrum by the force f of the compression springs 13, 13'. swings the rear end of the latch member 39 downward with one hand to avoid the lower end of the vertically bent portion 39a above the projection member 37, grips the handle 19 with the other hand, and applies the spring force of the tension spring 32. When the parking member 15 is pulled out backwards (towards the user for the user) and released with one hand after being pulled out a little, the parking member 15 moves towards the support rollers 24, 24' and the support guide member 6. It moves backward while being guided by support rollers 20, 21, 20', 21' and guide rollers 22, 23, 22', 23'. The pulling force in this case is reduced to 1/2 by the double pulley action of the fixed pulley group 28 and the movable pulley 30. When the parking member 15 is moved slightly backward and then pulled down, the parking member 15 is integrated with the support guide member 6 into the support shaft 1.
It rotates clockwise (as shown in FIG. 8) about 0 as a fulcrum and separates upward from the support rollers 24, 24'. Along with this rotation, the pivot points of the hook-shaped arms 14, 14' move from _X1 to the dead center _X2 , and the amount of eccentricity gradually decreases from _d1 to O, so that the support The counterclockwise moment that the guide member 6 receives, that is, the upward moment at the rear of the support guide member 6 gradually becomes smaller. After the rotation, the weight of the parking member 15 acts greatly together with the decrease in the moment, and the parking member 15 rotates downward together with the support guide member 6 just by a light force applied by the user. While moving backward, park the parking member 15 as shown by the solid line in Figure 8.
When the parking frame 16 is fully pulled out and the front stopper plate 35 comes into contact with the support plates 7, 7', the rear lower end of the parking frame 16 is brought into contact with the ground floor 3 as shown by the two-dot chain line in the figure. In this state, the pivot points of the hook-shaped arms 14, 14' extend beyond the dead center _X2 and point to the opposite side _X3.
Since the support guide member 6 has reached the position, the support guide member 6 is receiving the compression spring force f, but the slight eccentricity in the opposite direction is d ₂
It receives a correspondingly slight clockwise moment, that is, a downward moment at the rear of the support guide member 6, and is fixed in that position.

Therefore, even if the user releases the handle 19, there is no danger that the parking member 15 will jump upwards.

Thus, the user mounts the bicycle J on the parking member 15 in the fixed state shown by the two-dot chain line in FIG.
Next, grasp the handle 19 and lift it slightly upward. At this time, contrary to the above-mentioned lowering operation, as the parking member 15 and the support guide member 6 integrally rotate upward, the pivot points of the hook-shaped arms 14, 14' move from _X3 to The counterclockwise moment received by the support guide member 6 gradually increases as it moves beyond the point _X2 toward _X1 , and this force is applied to the tension spring 32, so the parking member 15 only applies a light force. While being guided by the support guide member 6, the inside of the fixed frame body 5 is pulled back forward.

In the above explanation, the parking spaces are arranged in multiple rows, but the support pillars, fixed frames, support guide members, parking members, etc. are arranged in one row.
The object of the present invention can be achieved even if the unit is used for parking only two cars, one above the other, and if a cushioning material such as rubber is added to the rear end grounding part of the parking member, it is safe and noise-free.

As detailed above, according to the present invention, it is possible to park in two levels, upper and lower, with simple equipment, and when unloading to the ground, a double pulley mechanism is used to provide support despite resisting the pulling spring force. The moment that forces the rear part of the guide member to rotate upward gradually decreases.
This moment, combined with the weight of the parking member, allows the parking member to be lowered with a small amount of operating force, and when the parking member is lowered downward, the point of action of the tension spring reaches its dead center. This creates a moment that rotates the rear part of the parking member downward and fixes it to the ground. Furthermore, when warehousing to the upper stage, the lifting spring force and the moment for rotating the rear part of the support and guide member upward increase as it rotates upward, so that warehousing can be carried out safely and smoothly with a small amount of human effort.

In addition, although the height positions of the upper parking spaces of adjacent parking members are staggered, if a shopping cart or luggage that protrudes abnormally is placed on a parked bicycle,
If the parking member is pulled down carelessly, these obstacles may get caught on the parked bicycle. However, even in this case, since the parking member in each storage state is prevented from moving backward by the lock mechanism, if the adjacent parking member is accidentally dragged down when being lowered in the above-mentioned stuck state, No further inconvenience occurs, and the user only has to perform the operation again to avoid the obstacle.

Furthermore, the support column, fixed frame, support guide member, and parking member are combined into one unit, and by increasing the number of units, the number of parking spaces can be easily increased, and no motor is required for operation. Not only is it an extremely inexpensive device because it requires only human power, but it can be safely handled by women and children as it can be loaded and unloaded with a small amount of human power as mentioned above, and its simple structure means that it rarely breaks down. .
