Abstract

PURPOSE:To simplify installation of a device by a method wherein a pallet is supported in a cantileverlike state by means of stays on both sides of the rear erected to a leg frame. CONSTITUTION:With a state in which a pallet 1 is lowered, an automobile C is placed on the pallet 1. When, with a control panel controlled, a drive geared motor mounted to the pallet 1 is run, a drive sprocket 15 is rotated in a state to be geared with a chain 11 and an auxiliary chain 12, and the pallet 1 is raised by means of the main chain 11 serving as a fixed rack. When the pallet 1 is then maintained approximately in a horizontal direction by means of rollers 9 and 10 of a frame 7 and raised by a given amount, rise of the pallet 1 is stopped, and a parking space is ensured below the pallet 1. When energization to the motor is disconnected, braking is applied to block lowering of the pallet 1.

Description

[Detailed description of the invention]

(a) Industrial application field The present invention relates to a two-tier parking device for parking a car on the lower two levels, and more specifically, the present invention relates to a two-tier parking device for parking a car on the lower two levels, and more specifically, the parts on which the car is placed are placed on two columns located at the rear. This invention relates to a two-stage, pillar-type parking device that is supported by a two-stage parking system. (b) Conventional technology Recently, due to high land prices and increase in automobiles, etc. In urban areas, there is a shortage of parking spaces, and two-tier parking systems are attracting attention in order to make effective use of space. Generally, in a two-tier parking device, a pallet is suspended and supported by four pillars on the front, rear, left, and right sides, and the pallet is raised and lowered by a hoisting mechanism made of wires, chains, etc. built into these four pillars. For this reason, the two front pillars become an obstacle when placing the car on a pallet, so-called parking. Especially when the road facing the parking device is narrow, the front two pillars obstruct the car and make it difficult to park the car in the garage. In addition, these front columns can get in the way when opening and closing the door.Furthermore, in order to drive the hoisting mechanisms of the four columns synchronously, an interlocking device that interlocks all of these hoisting mechanisms is required. is necessary, which complicates the structure. Therefore, various two-tier parking devices have been devised in which a pallet is supported by two or one support. For example, a pallet is supported by one branch at the center of both the left and right sides via a guy 1-roller so that it can be raised and lowered, and two columns on both sides drive the pallet up and down using lifting devices such as hydraulic cylinders and hoists. One-post system on each side, where the pallet is supported by one post at the center of either the left or right side, and the two-post system on each side, where the barre/soto is supported by two posts at the front or rear of either the left or right side. There is also a rear single-post system in which the rear end of the barre-soto is guided by a single central post and is driven up and down by a hydraulic cylinder via a link. (c) Problems to be solved by the invention However, although the two-pole system on both sides improves the ease of parking, there are many problems with getting in and out of the car because there is a pillar in the center. In order to erect it, foundation work is required. . In addition, with the one-post system on each side, it may be possible to improve the ability to get on and off from one side, but the "C" problem still occurs when getting on and off from the other side, and a large overturning torque acts on one post. Therefore, large-scale foundation work is required to firmly support the pillars.In addition, although the two-pole system on one side improves the ease of entering and exiting the garage from one side, it is difficult to enter the garage from the other side. Moreover, the ease of getting on and off the pallet is not improved, and large-scale foundation work is required because the column overturning torque acts as described above.Furthermore, in the rear single column system, a hydraulic cylinder is installed at the rear end of the pallet to raise and lower the pallet. It requires a special space such as a hydraulic cylinder and a link, which is not space efficient.It also requires a hydraulic cylinder and has poor energy efficiency because it converts electrical energy into hydraulic pressure.Furthermore, the problem of hydraulic leakage is unavoidable, so it is not possible to use a link. Combined with the complicated structure, there is a risk of a lack of reliability.Therefore, the present invention improves the ease of entering and exiting the garage by adopting a two-support system on both sides of the rear, and also reduces the need for foundation work for installing the supports. It is an object of the present invention to provide a two-tier parking device which can be of a mounted type without the need for a parking device and which also improves reliability. For example, as shown with reference to FIGS. 1 to 3,
The pallet (1) on which C) can be placed is placed between the supports (2) and (2).
In the two-stage parking device (3), which is guided so as to be raised and lowered by the pallet, and which drives the pallet (1) up and down; Leg play) (6) and (6) respectively have the above-mentioned pillars (2). (2) are erected, and support frames (7

put it in the garage. At this time, the two-stage parking device (3) does not have a support in front of it, so even if the 1111 road is narrow, the driver can easily park the garage without being obstructed by the support. Even if the door on the driving sound side of a car is on either the left or right side, it can be opened and closed without being obstructed by the branch office, and the driver can easily get out of the car (C).

Due to the presence of the chain (11,), (12), the drive sprocket (15a), (15b) is sufficiently wrapped around the corner, which prevents the chain and sprocket from coming off, and also prevents the chain from coming off. The load is distributed and supported by the chain links and sprocket teeth. Further, the weight load acting on the pallet (1) normally acts only on the main chain (1F) and does not act on the auxiliary chain (12). Therefore, depending on the use, the auxiliary chain (12)
Even if the main chain (11) breaks, the auxiliary chain (12) or butt (1) can be reliably supported after the play (17) moves. . Note that although the above-mentioned symbols in parentheses are in contrast to the 11th surface, they do not limit the same structure. Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. The two-stage parking device 3, as shown in FIGS. 1 to 4,

is erected parallel to the pillar 2. Furthermore, the upper end of the member 19 and the support column 2 are connected and reinforced by a beam-like reinforcing member 21 and a brace-like auxiliary member 22. A large number of sliding grooves are formed along its length, and the wall thickness becomes progressively thicker from the front to the rear (see Figure 4). In addition, a box-shaped projection 40 for storing a drive motor etc. is formed in the center of the rear part of the body and slightly protrudes from the upper surface of the thick part, and rollers 27 for preventing lateral vibration of 1V are rotatably supported on both sides of the rear end. In addition, the guide plate 36 may be attached only to the right side in the drawing, or it may be attached to the left side depending on the situation of the road ahead, or it may be attached to both the left and right sides. As shown in FIG. 7, rails 4a, 4a are formed inside the support column 2.2 over its entire length.Furthermore, on both rear sides of the pallet 1,
A support frame 7.7 is fixed upwardly at a substantially right angle to the pallet 1, and rollers 9.10 are rotatably supported at the upper and lower ends of the support frame. The upper roller 9 rolls into contact with the front wall of the rail 4a, and the lower roller 10 rolls into contact with the rear wall of the rail 4a, supporting the pallet 1 in a cantilevered state while maintaining the horizontal state and allowing it to move up and down. . Furthermore, supporting members 26 and 26 are fixedly installed on both sides of the rear part of the pawn knot, and rotatably support the rollers 27, 27 for preventing lateral vibration. It makes contact with the ball and prevents the lateral swing of the barre. A chain 11 serves as a fixed rack for the lifting drive device.

．． 23, the tension of the chain is adjusted and applied. - On the other hand, one chain 11 is directly fixed to the upper end of the cover member 19 by a bolt 37 and a nut 39, and the other chain 12 is fixed to the upper end of the cover member 19 by a bolt 17)) and a knot. 17c, therefore one chain 1
1 constitutes the main chain on which the driving force for raising and lowering the pallet 1 always acts, and the other chain 12 is normally absorbed by the drive 11 and the spring 17a and does not act.
It constitutes an auxiliary chain that functions only when the main chain 11 is cut. Further, brackets 30 are fixed to both sides of the pallet 1, and an interlocking drive shaft 31 is rotatably supported by bearings 29 and 29 attached to both brackets 30. At both left and right ends of the interlocking drive shaft 31 protruding outward from the bracket 30, there are two
driving sprockets 15a, 15b, 15

The main chain 11 and the auxiliary chain 12 have drive sprockets 15a and 1 located downward from one side.
5b, and the idler sprocket 16 located above;
．． It is wound so as to extend downward toward 23. Furthermore, a drive geared motor 13 with a built-in brake is disposed inside the box-shaped protrusion 40 in the thick part of the pallet 1 along the axial direction of the interlocking drive shaft 31, and an output shaft of the geared motor 13 is further disposed. A drive gear 33 is fixed to the drive gear 33, and the drive gear 33 meshes with a driven gear 35 fixed to the interlocking drive shaft 31. Next, the operation of the present two-tier parking device 3 will be explained. With the pallet 1 lowered, the driver places the car C on the pallet 1. At this time, since the present two-tier parking device 3 does not have a support on the front side, the support does not get in the way when parking the car in the garage, and the guide plate 36 protruding from the front side allows the front to move forward. Even when the road is narrow, the car can be easily placed on the pallet 1, and the driver can easily get out of the car without any props getting in the way when opening either the left or right door. Note that the drive geared motor 13 and gears 33 and 35 protrude above the pallet 1.
The box-shaped protrusion 40 that accommodates the box-like projection 40 is arranged so as to avoid the lowest ground height of the vehicle, so that it does not interfere with the bottom of the vehicle. Then, by operating the operation panel, the driver drives the drive car 1 to motor 1:3, and the rotation of the motor is transmitted to the interlocking drive shaft 31 via the float 33.35, and the rotation is driven. The signal is transmitted to sprockets 15a and 15b. 1τ亥1) The μ moving sprocket rotates while meshing with the main chain 11 and the auxiliary chain 12, and the main chain 11 is used as a fixed rack to hold the pallet 1.
let At this time, even if the pallet 1 shakes sideways due to vibrations caused by the lifting and lowering, the rollers 27 fixed to the pallet 1 and the chisel 1 to rail 26 that guide the t-rollers 27 prevent the pallet 1 from shaking sideways 11T. In addition, in the said parcel 1, there is

The load is transmitted to the column 2 via the rows 3 and 10 of the support frame 7, and is further supported by the leg plates 5 extending beyond the center of gravity. Then, when it rises by a predetermined amount, t・jl・1・kir: t +, 艷f−

The main chain 11 and the auxiliary chain 12 are connected to drive sprockets 15a, 15b and idler sprockets 16a, 16.
By b, the chain is sufficiently wrapped around the corners to prevent the chain from falling off the sprocket, and the load is supported in a distributed manner by the large number of chain links and sprocket teeth. Furthermore, normally the weight of the pallet 1 acts only on the main chain 11 and not on the auxiliary chain 12. As a result, auxiliary chain 1
2 is free from wear and fatigue, and even if the main chain 11 breaks, the auxiliary chain, which is as good as new, will reliably support the pallet 17 after moving by the amount of play 17 at its upper end. (g) As described in detail, according to the present invention, the pallet (1) is supported cantilevered by the two pillars (2), (2) 17, - on both rear sides, so that the pallet (1) can not be placed in the garage by the pillars. Moreover, it does not interfere with the opening and closing of the door, and improves the performance of parking the vehicle in the garage and the performance of the driver getting on and off the vehicle. Also, the two pillars (2), (2) are leg frames (6). (6) The overturning torque acting on the pallet (1), which is erected, is supported by the leg frame via the pillars.
