Description

[Detailed description of the invention] <Industrial application field> The present invention is a vertically movable shelf used in general stock shelves, tableware disinfection storage cabinets that store large quantities of tableware, cold storage cabinets, etc. This invention relates to a device for lifting and lowering members.

<Prior art> Conventionally, as a stock shelf for placing and stocking a large number of articles on a shelf board, a stocking device in which each shelf board is suspended from above by a chain or wire was developed in 1988-44807. It is proposed by the publication No.

When this storage device does not store items,
All the shelves are lowered and stacked, and each time a shelf is used to place an item, each shelf is raised in sequence using a chain or wire to increase the number of items stored. It has a very good structure.

<Problems to be solved by the invention> However, although the edges of each shelf board are connected to four chains, etc. at regular intervals, the chains of each shelf board are almost completely irremovably connected. Therefore, there was a problem in that the interval between the shelf boards could not be easily changed depending on the size of the stored items. Also,
When the shelves are lowered and stacked, the chains and wires bend randomly on both sides of the shelves, resulting in an unsightly appearance, and the chain rings may get caught on other parts, such as the protrusions on the connecting parts. There was a risk that the shelves would not be able to rise horizontally.

The present invention was made to solve the above problems, and it is possible to easily change the mounting position of the shelf member to the hanging tool and to easily remove the shelf member.
To provide a shelf member elevating device capable of creating an orderly state by bending hanging tools in a certain direction when the shelf members are lowered to a stacked state.

<Means for Solving the Problems> For this purpose, the shelf member elevating device of the present invention has four shelves in which a plurality of shelf members are suspended from above within a shelf frame.
In a shelf member lifting device that is arranged so that it can be raised and lowered by being supported by book hanging devices at approximately four corners, and is equipped with a hoisting device that winds up the book hanging devices, shelf supports are arranged at regular intervals on two book hanging devices on both sides. is held horizontally, the shelf member is horizontally locked between both shelf support members,
It is constructed by providing bending directivity imparting means for imparting bending directivity to the hanging tool between the shelf support members.

<Function> In this way, the shelf member is held by the hanger and the shelf member is locked to the shelf member, so that the shelf member can be easily attached and detached depending on the stored items. In addition, since the hanging tools between each shelf member are given a certain bending directionality, when the shelf members are lowered and stacked, the hanging tools between them will bend only inward, for example, and will not bend in an orderly manner. The problem caused by creating a condition and bending randomly is eliminated.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

Fig. 1 shows a front view of a shelf device having a shelf member 2 that can be raised and lowered, and Fig. 2 shows a right side view thereof. A plurality of members 2 are supported so as to be horizontally movable. Four hanging tools 3a to 3d are suspended from above within the shelf frame 1, and shelf support members are attached at regular intervals to both sides of these hanging tools 3a to 3d. That is, the right side shelf support member 20 is horizontally fixed to the hangers 3a and 3d, and the left side shelf support member 20 is horizontally fixed to the hangers 3b and 3c. Hanging tools 3a to 3d
As the material, a wire rope, a thin wire, or a wire rope whose periphery is covered with fibers can be used, and a rope that is flexible and can be elastically deformed to some extent is preferable.

Convex curved surface portions 20a are provided at both ends of the shelf support member 20.
As shown in FIG. 3, hanging tools 3a to 3d hanging down from above are pressed and fixed to the curved surface portion 20a of this shelf support member 20 by a presser 4, and are connected so as to extend downward. . Presser foot 4
is fastened and fixed to the shelf support member 20 with screws 16 so as to press the hanger against the curved surface portion 20a. This holding tool 4 holds the metal plate on the curved surface part 2 of the hanging tool.
It is bent into a semicircular cross section so as to have an inner surface with approximately the same curvature as 0a, and the upper and lower edges are bent slightly outward, and mounting holes for passing the screws 16 are provided on both sides. Note that, in order to prevent the hanging tool from slipping, the curved surface portion 20a and the inner peripheral surface of the presser tool may be subjected to blank processing, uneven processing, or the like.

In this way, since the hanging tools 3a to 3d are press-fixed to the curved surface portion 20a of the shelf support member 20, the entry side and the exit side of the hanging tools following this fixed portion will be in the first position when no vertical tension is applied. As shown in FIG. 5, it acts so as to extend in the tangential direction of the curved surface portion 20a. As a result, the hanging tools 3a to 3 between the upper and lower shelf support members 20
d is given an inward bending directionality (inward direction of the shelf member).

In addition, two pairs of hanging tools 3a, 3d and 3 on both sides
A plurality of shelf support members 20 are connected to each of b and 3c at regular intervals in the form of a ladder, the lower ends of each of the hangings 3a to 3d are fixed to the lower part of the shelf frame 1, and the upper ends thereof are fixed to the lower part of the shelf frame 1. It is hooked onto and connected to the winding rollers 6 to 9 of the winding device 5 provided.

As shown in FIG.
One shaft 10 is supported horizontally directly above a and 3d,
Four winding rollers 6 to 9 are mounted on a shaft 10, and the shaft 10 is connected to a motor 11 with a reducer mounted on a shelf frame.
are connected by a chain and a sprocket, and a motor 11 drives a shaft 10 to rotate in the direction of the arrow in FIG. The winding roller 6 is located directly above the hanging tool 3a, the winding roller 8 is located right above the hanging tool 3d,
The upper end of the hanging tool 3a projects onto the upper plate of the shelf frame 1 and is immediately connected to the winding roller 6, and the upper end of the hanging tool 3d is similarly connected to the winding roller 8.

On the other hand, guide pulleys 12 and 13 are provided on the left side of the shelf frame 1 in FIG. Similarly, the lifting tool 3c is also bent in the direction of the hoisting device 5 via the guide pulley 13, the tip of the lifting tool 3b is connected to the hoisting roller 7, and the tip of the lifting tool 3c is bent in the direction of the hoisting device 5. It is connected to roller 9.

Since the winding rollers 6 and 7 and the winding rollers 8 and 9 of the winding device 5 are located close to each other, it is also possible to form two grooves on the same roller. Further, a limit switch 14 is provided at the top of the shelf frame 1 to detect the rising end of the shelf member 2, and when the uppermost shelf member 2 reaches the rising end, the rod is pushed up and the limit switch 14 is pushed by the rod.
The operation of this switch causes the motor 11 of the hoisting device 5 to be stopped.

The shelf member 2 is formed into a pipe frame structure as shown in FIG. It is horizontally locked between the shelf support members 20 on both sides so that the corner notches fit into the shelf support members.

In order to simplify the structure, guide rails for guiding the vertical movement of each shelf member 2 are not provided, but guide rails may be provided to prevent the shelf members 2 from shaking.

The shelf device configured in this manner is used, for example, when the shelf is not in use or when there are few stored items 15, with all the shelf members 2 positioned at the lowest position, as shown in FIG.

In this case, each hanging tool 3a to 3d is connected to each shelf support member 2.
Since it is pressed and fixed to the curved surface portion 20a of 0 from the outside by the presser 4, bending directionality is imparted to the inside when the hangers 3a to 3d are not tensioned, and the shelf members 2 in the stacked state are The hanging tools 3a to 3d in between are each neatly bent inward as shown in FIG. Therefore, the hangers 3a to 3d between the stacked shelf members may be bent in an unsightly manner, or the hangers bent outward may be caught between the shelf frame 1, or may be damaged by other members. There will be no sagging problems.

When placing many stored items, the hoisting device 5 is driven to rotate the hoisting rollers 6 to 9 in the counterclockwise direction in FIG.
to raise the shelf member 2. Hanging tool 3
The shelf members 2 are pulled up in sequence from the upper tier by winding up steps a to 3d, and when two tiers of shelf members are used, the shelf members 2 are in a state as shown in FIG. 7. In this case as well, since the stored items 15 can be placed on the shelf member at a low position, it is easy to take in and take out the stored items.

If you want to put more items on the shelf,
Similarly to the above, the hoisting device 5 is driven to raise the shelf members 2 in order, and the stored items 15 are placed in order on the newly spaced lower shelf members 2,
If the uppermost shelf board 2 is raised until it reaches the upper limit, the stored items 15 can be placed using all the shelf members 2.

Further, since the shelf member 2 can be easily attached to and removed from the shelf support member 20, tall items can be stored by removing any shelf member 2 as shown in FIG.

When taking out the stored item 15, perform the operation opposite to the above, and start taking out the stored item at the lowest level.As the stored item 15 is taken out, the hoisting device 5 is rotated in the opposite direction, and the lifting devices 3a to 3d and lowering the shelf members 2 in order, the stored items 15 are always taken out at the lowest position, making it easy to take out the items.

Therefore, even if the height of the shelf is increased, the number of items stored
5 can be easily put in and taken out.

On the other hand, when changing the height position, that is, the vertical spacing of the shelf support member 20, loosen the screw 16 and
This can be easily done by shifting the fixing position to the shelf support member 20 in ~3d, and there is almost no damage to the hanging tool even if the position of the shelf support member 20 relative to the hanging tool is changed, so the hanging tool can be used for a long period of time. can be used.

FIG. 9 is a perspective view showing another embodiment, in which holes are provided at both ends of a rectangular plate-shaped shelf support member 30, and hanging tools 3a to 3d are vertically inserted into these holes. On the other hand, stoppers 31 are screwed to the hangers 3a to 3d at regular intervals.
The shelf support member 30 is supported by the shelf support member 30, and the shelf member 2 is locked onto the shelf support member 30 so that the notches at the lower four corners of the shelf member 2 are fitted. Furthermore, the hanging tool 3a
A bender 32 is attached to the intermediate portion of ~3d.
This bending member 32 surrounds the hanging tools and is formed in a substantially dogleg shape, and acts to slightly bend the hanging tools 3a to 3d. Therefore, these benders 3
If the bending direction of 2 is set to a certain direction inside the shelf members 2, when the shelf members 2 are lowered and stacked, the hanging tools 3a to 3d can be bent in an orderly manner inside between the shelf members 2. I can do it.

In the above embodiment, the curved surface portion 20a is formed at the end of the shelf support member 20, but even if the curved surface portion 20a is formed as an end with a rectangular cross section and a presser with a substantially trapezoidal cross section is pressed and fixed thereon, the hanging tool will not bend. can be given gender.

<Effects of the invention> As explained above, according to the shelf member lifting device of the present invention, the shelf members are held at regular intervals by the hanging tools, and the shelf members are supported by the shelf members, so that the shelf members can be easily moved. By widening the space between the shelf members, it is possible to store large items. In addition, since bending directionality is imparted to the hanging tools between the shelf members by the bending directionality imparting means,
When the shelf members are lowered and stacked, the hanging tools between the shelf members are bent in a certain direction and are arranged in an orderly manner, preventing problems such as the hanging tools getting caught between the shelf frames or getting tangled. Does not occur.
