DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage device in which a storage object is placed and stored on a vertically movable mounting table. It is applied as a device.

[0002]

2. Description of the Related Art Conventionally, as a parking device for an automobile, for example, there is one as shown in FIGS. As shown in the figure, the parking device includes a pair of left and right ground beams 41, and the rear ends of the ground beams 41 are connected to each other via a connecting rod 42. The front and rear ends of each of the ground beams 41 are respectively provided with front support columns 43A and 44A and rear support columns 43B and 44B.
Is erected.

A rotating shaft 45 is rotatably supported between upper ends of a front support 43A and a rear support 43B located on the left side of FIG. 7, and sprockets 46 and 47 are fixed to both ends of the rotary support 45, respectively. Have been. Also, the front column 43
A motor 51 is installed at the upper end of the motor A.
The rotation shaft 45 is normally and reversely rotated with the driving of. On the other hand, one end of a chain 48 is fixed to the inner top of the front support 44A and the rear support 44B located on the right side, and the other end of the chain 48 is hung on each of the sprockets 46 and 47 and hangs downward. Have been. And, between these four pillars 43A, 43B, 44A, 44B, the automobile C
A pallet 49 for mounting is suspended and supported by a chain 48. Sprockets 50 are provided on both front and rear sides of the pallet 49.
0 is engaged with the chain 48. And the motor 5
When the rotation shaft 45 is rotated in the forward and reverse directions by the drive of 1, the chain 48 is extended and retracted through the sprockets 46 and 47, and the pallet 49 is raised and lowered.

[0004]

In the parking device constructed as described above, when the car C is placed on the pallet 49, the chain 48 is extended by driving the motor 51, and as shown in FIG. The pallet 49 is lowered. However, as shown in the figure, there is a connecting rod 42 for connecting the left and right ground beams 41 below the rear end of the pallet 49.
Can't descend further down. Therefore, in the conventional apparatus, even if the pallet 49 is lowered most, the automatic loading side at the front end side of the pallet 49 rises from the ground surface by the height of the connecting rod 42. Therefore, the vehicle C cannot be smoothly placed on the pallet 49, and in some cases, the underbody of the vehicle C may interfere with the front end of the pallet 49 when the vehicle C is loaded, and the underbody may be damaged. there were.

[0005] In order to solve this problem, it is conceivable to displace the connecting rod 42 backward to a position where it does not interfere with the pallet 49, as shown by a chain line in FIG. However, in the case of such a configuration, there is a problem that the front-rear length of the device increases, and the installation area of the entire device increases. In particular, the main purpose of this parking device is to park the car C on the pallet 49 and above and below it in the upper and lower parts so that the site can be used effectively, so that the parking device is installed. It was necessary to avoid increasing the area as much as possible. Moreover, this connecting rod 42
Is a car C parked on the ground below the pallet 49
When the connecting rod 42 is shifted backward, the car C is also shifted rearward and parked on the ground. Therefore, in this case, the vehicle C is largely shifted back and forth between the ground portion and the pallet 49, and it is necessary to secure a space for the vehicle C behind the apparatus.

When the pallet 49 is lowered, if the chain 48 is further extended while the rear end of the pallet 49 is in contact with the upper surface of the connecting rod 42, the pallet 49 has its front end owing to its own weight. It is lowered to the position where it contacts the ground surface. However, at this time, pallet 4
9 is not lowered, so the rear struts 43B, 44
On the B side, there is a problem that the chain 48 becomes loose and the chain 48 may come off the sprocket 50.

Further, it is conceivable that the device is buried in the ground by the height of the connecting rod 42, or that a slope is formed to smoothly connect the front end of the pallet 49 and the ground surface. However, in such a case, it takes a lot of time and effort to install the apparatus, and the installation operation becomes complicated, and the apparatus cannot be easily moved.

Incidentally, the four pillars 43 as described above are used.
In the parking device having A, 43B, 44A, and 44B, the connecting rod 42 must be provided for connecting the left and right ground beams 41 and ensuring the rigidity of the entire device, and cannot be omitted. For this reason, various problems as described above occur.

In the conventional parking device, since the pallet 49 is raised and lowered in a horizontal state, the vehicle C may fall off from the front end of the pallet 49 when subjected to vibration such as an earthquake. Therefore, as shown in FIGS. 7 and 8,
In the conventional device, a wheel stopper 52 is provided on a pallet 49. Therefore, the number of parts is increased, and it is necessary to get over the wheel stopper 52 when the vehicle C gets on and off, so that there is a problem that smooth getting on and off cannot be performed.

The present invention was made to solve the above problems, and an object, it is possible to incorporated rides the car smoothly on the table, the automatic
The car can be placed on the mounting table without fear of falling off,
Moreover, it is an object of the present invention to provide a storage device capable of minimizing an installation area.

[0011]

In order to achieve the above-mentioned object, according to the first aspect of the present invention, a mounting table for mounting an automobile is provided with a cable on an automatic vehicle mounting side and a mounting rear side thereof. In a storage device for a vehicle provided with a lifting mechanism for lifting and lowering by suspending and supporting by a member, the lifting mechanism comprises a pair of grounds having rear ends connected to each other via a connecting rod.
It is erected between a pair of front struts and a pair of rear struts respectively erected at the front and rear ends of the beam, and is rotatable between a cable-like member for suspending and supporting the mounting table and one of the front and rear struts. The supported rotating shaft and the front and rear struts are respectively fixed to the rotating shaft at positions corresponding to the rotating shaft, and the one end side of the cord-like member is extended and retracted with the rotation of the rotating shaft, and the mounting table is described. a rotating body for lifting the, and a driving means for rotationally driving the rotating shaft, the rotating body of the front pillar side, and a larger diameter than the rotating body of the rear pillar side, the mounting table, under In the lowered position, the rear end of the mounting table is
The ratio of the diameter of the rotating body on the front column side to the rotating body on the rear column side is set so that the rotating body on the front column side and the rotating body on the rear column side are arranged in a slightly downwardly inclined state toward the front by being lifted by the height from the upper surface. It is a thing.

[0012]

According to the second aspect of the present invention, a support member for connecting and supporting the other end of the cord-shaped member is provided on the other front and rear struts so as to be vertically movable, and resists the pulling force of the cord-shaped member. And a biasing member for constantly biasing the support member.

[0014]

Therefore, according to the first aspect of the present invention, the lifting / lowering speed of the mounting table by the lifting / lowering mechanism is set to be different from each other between the storage object loading side and the loading depth side of the mounting table. . Therefore, for example, if the lifting speed on the automatic loading side is set faster than the lifting speed on the loading depth side, when the loading table is lowered and the loading side contacts the ground surface, the loading depth of the loading table Can be located above it. Therefore, even if the left and right supports are connected by connecting rods on the rear side, the connecting rods do not hinder the lowering of the mounting table, and the position where the automatic mounting side of the mounting table abuts on the ground surface. Can be lowered to As a result, the stored object can be smoothly placed on the mounting table, and it is not necessary to displace the connecting rod backward to a position where it does not interfere with the mounting table. Can be .

Further, when the rotating body is rotated together with the rotating shaft by the driving means, one end side of the cord-like member is extended and retracted through each rotating body, and the mounting table is raised and lowered. At this time, since the rotating body on the front column side is formed to have a larger diameter than the rotating body on the rear column side, the cord-like member on the front column side has a higher extension and retraction speed. That is,
As for the mounting table, the vertical movement speed is higher on the automatic loading side on the front end side than on the rear end side.

According to the second aspect of the present invention, the support member is constantly urged against the pulling force of the cord-like member by the urging member. Therefore, for example, even if the cable-like member becomes loose, the support member is urged by the urging member and the cable-like member is pulled, so that the cable-like member is maintained in a tensioned state.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the storage device of the present invention is embodied in a car parking device will be described below with reference to the drawings.

As shown in FIGS. 1 to 4, the parking device 1 includes a pair of left and right ground beams 2, and the rear ends of the ground beams 2 are connected to each other via a connecting rod 3. The front struts 4A, 5A and the rear struts 4B, 5B having a U-shaped cross section are erected at both front and rear ends of each ground beam 2 respectively. Bottom plate 6
Is disposed between the both beams 2 and the connecting rod 3.
The connecting rod 3 connects the left and right ground beams 2 and the columns 4 and 5 to each other, and secures the rigidity of the entire apparatus.

The chain stopper 7 is supported on the upper ends of the front and rear columns 5A and 5B located on the right side of FIGS. 3 and 4, respectively, and one end of the chain 8 as a cord-like member is positioned inside the columns 5A and 5B. Each chain stopper 7 is connected and fixed.

Here, the structure of the chain stopper 7 will be described in detail. As shown in FIG.
A through hole 9 is formed in the upper end surface of 5B, and a spring housing cylinder 10 having a bottomed cylindrical shape is fixed to the inner top surfaces of the columns 5A and 5B so as to surround the through hole 9. A coil spring 11 as an urging member is housed in a spring housing tube 10.
Further, a through hole 10a is formed in the bottom surface of the spring housing cylinder 10,
The support member 12 is provided in the through hole 10a and the coil spring 11.
Is inserted to be able to move up and down. The support member 12 has a shaft 13, and the upper end of the shaft 13 protrudes upward from the through hole 9 in the upper end surface of the columns 5 </ b> A and 5 </ b> B.
The projecting end of the shaft 13 has a flange 1
4 is fixed by a nut 15, and the upper end of the coil spring 11 contacts the flange 14. One end of the chain 8 is connected to a lower end of the shaft 13.

When a downward pulling force acts on the chain 8, the coil spring 1 is turned on as shown by the solid line in FIG.
1 is compressed between the flange 14 and the bottom surface of the spring accommodating cylinder 10, and the spring 11 generates an accumulating force. Accordingly, the support member 12 is urged by the coil spring 11 in a direction opposite to the direction in which the chain 8 is pulled. When the chain 8 is loosened, as shown by a chain line in FIG.
Is released and the spring 11 supports the support member 12.
Is urged upward, and the chain 8 is always maintained in tension.

As shown in FIGS. 1-4, the storage box 1
Reference numeral 6 is attached to the upper end of the left front column 4A, and a counter shaft 17 as a rotating shaft is rotatably supported between the storage box 16 and the upper end of the left rear column 4B. The sprocket 18 as a rotating body is
It is fixed to one end of the counter shaft 17 in the storage box 16. A sprocket 19 also serving as a rotating body is fixed to the other end of the counter shaft 17 in the left rear column 4B. The other end of the chain 8, one end of which is connected to the support member 12, is hung on each of the sprockets 18 and 19 and hangs downward.

A motor 20 as a driving means is disposed in the storage box 16, and a driving sprocket 21 is fixed to a driving shaft thereof. The driven sprocket 22 is also fixed to the counter shaft 17 in the storage box 16, and the driven sprocket 22 and the driving sprocket 21 are operatively connected via an endless transmission chain 23. Accordingly, the countershaft 17 is rotated forward and backward with the driving of the motor 20.

The pallet 24 serving as a mounting table has a rectangular plate shape, and the pallet 24 has four columns 4A, 4B, 5
A chain is supported by the chain 8 between A and 5B. The guides 25 are fixed to the front and rear sides of the pallet 24, respectively. A sprocket 26 is rotatably supported on each guide 25. Each guide body 25 is vertically movably accommodated in the columns 4A, 4B, 5A, 5B, and the sprocket 26 is engaged with the chain 8 from above.

Therefore, when the sprockets 18 and 19 are rotated forward and backward together with the countershaft 17 with the driving of the motor 20, the chain 8 is driven in and out through the sprockets 18 and 19. Then, the pallet 26 is moved via the guide body 25 to the columns 4A, 4B, 5A, 5B.
Are guided up and down while being guided along the length direction, and are arranged at a lowered position shown in FIG. 1 and a raised position shown in FIG. In this embodiment, a lifting mechanism is constituted by the chain 8, the counter shaft 17, the sprockets 18, 19, the motor 20, and the like. In addition, concave grooves 27 for allowing the chain 8 to pass therethrough are formed in front and rear of the lower surface of the pallet 24 so as to extend in the width direction of the pallet 24, respectively.

The upper surface of the pallet 24 constitutes a mounting surface 28 on which the vehicle C as a storage object is mounted. The left and right edges and the rear edge of the mounting surface 28 are raised upward. , Respectively, constitute a regulating portion 29 and a vehicle stop 30. The front end side of the mounting surface 28 is formed so as to be inclined downward as it goes forward, and forms a guide surface 28a.
Further, the front end side of the lower surface of the pallet 24 is a slope 24a which is formed to be inclined upward toward the front.

The sprocket 18 on the front support 4A has a larger diameter than the sprocket 19 on the rear support 4B.
The number of teeth formed on the outer circumference of the sprocket 18 is larger than the number of teeth formed on the outer circumference of the sprocket 19. Therefore, when the sprockets 18 and 19 are rotated forward and backward together with the counter shaft 17, the chain 8 corresponding to the sprocket 18 on the front support 4A is more than the chain 8 corresponding to the sprocket 19 on the rear support 4B. The feeding and feeding speed is increased. That is, the pallet 24 has a higher vertical speed at the front end side than at the rear end side.

In the present embodiment, as shown in FIG. 2, the pallet 24 is disposed at a raised position in a slightly upwardly inclined state toward the front. Then, when the pallet 24 is lowered from its raised position to the lowered position shown in FIG. 1, the ratio of the diameters of the two sprockets 18 and 19 is set so that the pallet 24 is slightly inclined forward. ing.

Next, the operation of the parking device for an automobile configured as described above will be described. When the automobile C is mounted by lowering the pallet 24, the countershaft 17 is rotated clockwise in FIG.
Then, each chain 8 is extended downward in the support 4A, 4B via each sprocket 18, 19, and the pallet 24 is lowered by the extension of these chains 8. At this time, since tension is applied to the chain 8 by the weight of the pallet 24, a downward pulling force is applied to the support member 12 of the chain stopper 7, and as shown by a solid line in FIG. The coil spring 11 is compressed and stored.

In this embodiment, the sprocket 18 on the front support 4A has a larger diameter than the sprocket 19 on the rear support 4B, so that the chain 8 on the sprocket 18 is closer to the sprocket 19. It is fed out at a speed faster than the chain 8. Therefore, as shown in FIG. 1, when the pallet 24 is lowered to the lowering position and its front end abuts on the ground surface and the drive of the motor 20 is stopped, the rear end of the pallet 24 is higher than the front end. Will be located. That is, the pallet 24 is arranged in a slightly downwardly inclined state toward the front.

For this reason, as shown in FIG.
Even when the rear end of the pallet 4 is lifted from the ground surface by the height of the connecting rod 3, the front end of the pallet 24 can be brought into contact with the ground surface. Moreover, in this case, the rear support 4B,
On the 5B side, since the chain 8 is not loosened, there is no possibility that the chain 8 will come off the sprockets 26 on the rear sides of the pallet 24.

Therefore, the vehicle C can be smoothly put on the pallet 24, and there is no possibility that the underbody is damaged when getting on the pallet 24. Also, for example, when the pallet 24 is lowered to the lowered position, the timing of stopping the drive of the motor 20 is delayed, and the chain 8 is loosened, the coil spring 11 of the chain stopper 7 may be used.
Is released, and the support member 12 is moved upward. Accordingly, since the chain 8 is pulled by the support member 12 and the chain 8 is always maintained in a tensioned state, there is no possibility that the chain 8 comes off the sprockets 26 on the front and rear sides of the pallet 24. Note that the spring force of the coil spring 11 is such that the chain 8 can be pulled up, but not so much as to pull up the pallet 24.

Next, when raising the pallet 24, the counter shaft 17 is rotated counterclockwise in FIG. Then, each chain 8 is retracted upward in the columns 4A, 4B via the respective sprockets 18, 19, and the pallet 24 is raised by the retraction of the chains 8. Also, at the time of this ascent, the chain 8 on the sprocket 18 side is repelled at a higher speed than the chain 8 on the sprocket 19 side, as at the time of the above-mentioned descent. Therefore, as shown in FIG. 2, when the pallet 24 is raised to the raised position and the driving of the motor 20 is stopped, the pallet 24 is arranged in a slightly upwardly inclined state toward the front.

[0034] For this reason, automatic car C on the pallet 24,
It is possible to reliably prevent the pallet 24 from slipping off from the front end side of the pallet 24 that is automatically mounted on the vehicle. In addition, since the wheel stopper 30 is formed in the rear end edge of the pallet 24,
Automobile C will never slip off from the rear end side of the pallet 24. Therefore, when causing boarded the vehicles C on the pallet 24, it is configured to be positioned slightly downward inclined state toward the same pallet 24 forward, by placing the pallet 24 in the raised position, the automatic Car C on pallet 2
4 can be stably mounted. Therefore, unlike the related art, there is no need to provide a wheel stopper on the pallet 24.

As described above, in this embodiment, with the pallet 24 lowered to the lowered position, the pallet 24 can be arranged in a slightly downwardly inclined state toward the front. Therefore, the vehicle C can be smoothly loaded on the pallet 24, and it is not necessary to displace the connecting rod 3 backward to a position where the connecting rod 3 does not interfere with the pallet 24, so that the installation area of the device can be minimized. it can.
In addition, as the pallet 24 rises, the pallet 24 gradually becomes slightly inclined forward.
There is no possibility that automobile C sliding down from the side narrowing rests car on the front end side of the pallet 24.

Incidentally, in the conventional parking device shown in FIG. 8, it is necessary to form the sloping guide surface on the front end side of the pallet 49 gently in order to make the entry of the car as smooth as possible. 49 protrudes forward. However, in the present embodiment, the pallet 24 itself may be inclined slightly downward toward the front, so that the inclined surface 24a is formed on the lower surface of the pallet 24 in addition to the guide surface 28a. Therefore, the protrusion of the pallet 24 can be suppressed accordingly. Therefore, this is also effective in reducing the installation area of the device.

In this embodiment, even if the chain 8 becomes loose for some reason, the chain stopper 7 prevents the chain 8 from being loosened.
Is pulled and is always kept in a tensioned state, so that it is possible to reliably prevent the chain 8 from being detached from the sprockets 26 on both the front and rear sides of the pallet 24, thereby preventing the pallet 24 from moving up and down.

Further, even when the chain 8 is entirely extended with the change in diameter, the coil spring 11 of the chain stopper 7 can be used.
Is released, the chain 8 is always maintained in a tensioned state. Further, since the coil spring 11 protrudes from the upper surfaces of the columns 5A and 5B in accordance with the elongation of the chain 8, it is possible to determine the elongation of the chain 8, that is, the life of the chain 8 based on the amount of protrusion.

When the pallet 24 is lowered to the lower position shown in FIG. 1, the timing for stopping the driving of the motor 20 may be slightly delayed to slightly move the support member 12 upward. In this way, when the motor 20 is started to start the retraction of the chain 8, the motor 20 is first loaded with a load enough to compress the coil spring 11, and thereafter, a large load necessary to raise the pallet 24 is applied. Load is applied. Therefore, when starting the motor 20, a large load is not suddenly applied to the motor 20, so that the starting power of the motor 20 can be reduced. Therefore, power consumption can be suppressed.

It should be noted that the present invention is not limited to the above-described embodiment, and may be embodied by changing the configuration of each unit as follows, for example, without departing from the spirit of the present invention. It is. (1) As shown in FIG. 6, the same motor 31 is arranged at the upper end of the front and rear columns 4A and 4B located on the left side, and the sprocket 1 is driven by the motor 31.
Rotate 8, 19 respectively. In this case, the rotation speeds of the sprockets 18 and 19 by the motor 31 are the same. (2) The present invention can be applied to various storage devices other than the parking device of a car.
To be embodied in a storage device for placing and storing objects. (3) The sprocket 19 on the side of the rear support 4B is connected to the countershaft 17 via a speed reduction mechanism including a plurality of gears.
Operatively connected to (4) A wire is used instead of the chain 8 as the cord-like member. In addition, corresponding to this, both sprockets 1
8 and 19 as winding drums and sprockets 2
6 is a guide pulley. In this case, each winding drum
It is needless to say that the diameters are different from each other. (5) The inclination ratio of the pallet 24 at the ascending position and the descending position is appropriately changed by appropriately changing the ratio of the diameters of the sprockets 18 and 19 .

[0041]

According to the present invention as described in detail above, it is possible to incorporated rides the car smoothly on the table, can be placed without fear of falling on the mounting table and the car Further, the installation area can be reduced as much as possible, and an excellent effect that the cord-like member is not loosened is exhibited.
