Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for automatically storing and laying chairs that can store a large number of chairs in a large conference hall, gymnasium, etc., and can efficiently lay the stored chairs.

[Conventional technology and its problems]

When using a gymnasium, exhibition hall, or large conference hall as a place for meetings or ceremonies, a large number of chairs must be arranged.
At the site, many people spend a long time arranging folding chairs, and when the work is finished, they have to clean them up, which is a difficult task.

In order to make this kind of work even a little easier, we use a stackable cooking chair 1 as shown in Figs. The chairs 1 are also stacked one on top of the other on a push-type rack 2. Although a large number of chairs 1 can be easily transported at one time by using such a hand-operated moving rack 2, loading and unloading the chairs 1 onto the hooks 2 still requires manpower and is labor-intensive. be. In particular, when the number of chairs increases, the loading and unloading positions become higher, making work more difficult.

Incidentally, stair-type movable seats are sometimes installed in large auditoriums, etc., but this requires quite a large amount of equipment, and the rear seats are quite high, making it difficult to approach and being heavy and damaging the floor. also occurs.

The purpose of the present invention is to eliminate the disadvantages of the conventional example, to automatically store and install chairs, and the device itself is compact and can be operated by one person, and it does not take up much space in the room. To provide a method for automatically storing and laying a chair that can be installed even in a room.

[Means for solving problems]

In order to achieve the above object, the present invention provides a large number of hooks on a cart so that they can be moved in both vertical directions in parallel at small intervals,
The gist is to use each hook to lift or lower horizontal tie members of chairs that can be stacked one after another.

[Effect]

According to the present invention, when storing, the chairs are hung one by one on the moving hooks while moving the trolley, so that the chairs hung at low positions can be automatically stacked up and down in a suspended state. can. Furthermore, when laying the chairs, by moving the hook in the opposite direction, the chairs that have been hoisted and stored can be sequentially lowered from the bottom while moving the trolley, and the chairs can be laid.

〔Example〕 Embodiments of the present invention will be described in detail below with reference to the drawings.

First, the apparatus used in the method of the present invention will be explained first.

FIGS. 1 and 2 show a first example, and numeral 3 in the figures is a truck having wheels 4. The trolley 3 may be of a self-propelled type equipped with a motor or of a hand-propelled type without a drive mechanism.

On the trolley 3, a large number of hooks 7 are provided protruding from a bar 5 in parallel at small intervals, and the bar 5 is provided to be movable up and down in both directions. In the figure, reference numeral 6 denotes a support holder for the bar 5. The bar 5 is slidably housed in the holder 6, and the hook 7 protrudes from the vertical slit of the holder 6.

Although not shown in the drawings, the mechanism for vertically moving the bar 5 may be one using a hydraulic or air cylinder as a driving source, a mechanism equipped with a lifting mechanism using a motor and gears or a chain, or a mechanism incorporating a screw jack inside the bar 5.
This can be moved using a motor or a manual handle.

This bar 5 is installed at a low and central position on the front side of the truck 3, and trapezoidal guide plates 8 extending in the left-right direction of the truck 3 are erected in parallel on both sides thereof.

Note that the width between the guide plates 8, 8 is narrower than the width between the legs 1a of the chair 1 of the stackable stand-up king chair, which will be described later, and the top (upper side portion) of the guide plate 8 is This corresponds to or is very close to the position of the hook 7 at the top of the bar 5 when it is completely housed.

Further, a lift 10 is provided along the oblique side 8a of the guide plate 8 with a hook 9 protruding from an endless band such as a link chain or belt, and a front plate 13 is provided upright on the front side of the truck 3. A sliding plate 14 was attached to the inside.

Next, the method of the present invention performed using the above-mentioned apparatus will be explained.

10 and 11 show a chair 1 targeted by the laying machine of the present invention. This is a cooking chair like the conventional one, and the backrest IC and the seat plate 1d are continuous, and there is a pipe underneath. Legs 1a with continuous lower ends made of material are provided on the left and right sides, and horizontal connecting members 1b are provided on the front surfaces of the legs 1a. Further, a convex portion 1e is provided on the lower surface of each leg 1a, so that the convex portion 1e makes contact with the floor or the like without rattling.

First, a case where such chairs 1 are arranged and stored will be described.

If the trolley 3 is advanced so that the ends of the guide plates 8, 8 are inserted between the legs la of the chair 1, the horizontal tie material 1
b corresponds to the oblique side 8a of the guide plate 8.

Furthermore, if the rift 10 is driven in this state, the endless band rotates and its hook 9 moves, and this connects the horizontal tie member 1b to another point laterally shifted from the contact point of the guide plate 8. The horizontal connecting member 1b is pushed up along the oblique side 8a of the guide plate 8 along with the movement of the endless band.

In this way, when the chair 1 ascends the guide plate 8 and reaches the upper end position of the bar 5 housed in the holder 6, the hook 7 at the top of the bar 5 is placed in the center of the horizontal tie member 1b. Then, the bar 5 rises by one pitch to suspend the chair 1.

Thereafter, the next chair 1 is also moved along the guide plate 8 by the lift 1.
0 and is suspended from the hook 7 of the next stage of the bar 5, and as shown in FIG. go. In this case, the front corner of the leg 1a of the chair 1 has a sliding plate 14
A stable holding condition can be obtained by making contact with the

As described above, once a large number of chairs 1 are stored in a suspended state, the trolley 3 itself can be placed in a place where it will not get in the way.

On the other hand, in order to lay out the chairs 1 stored on the multi-carriage 3, the operation reverse to the above-mentioned storage is performed. That is, the chair 10 is reversed, and the bar 5 is lowered one pitch at a time, starting with the lowest chair 1, and placed on the floor in order to set it in a predetermined position.

FIG. 4 shows a second example of the device, in which a vertical lift chain 11 is provided in place of the liftable bar 5, and hooks 12 protruding from each pitch of each component link of this lift chain 11 are used to lift the chair. 1 can be hung and stored.

In addition, in both the first example and the second example, the mechanism for pushing up the chair 1 along the guide plate 8 is a lifting mechanism using an endless body.
In place of the lift chain 11, a rotatable telescoping arm with a hook at the end is provided, and the end is used as a hook to hang the chair 1 on the flanges, and by reducing the size of the arm, the chair 1 is It is also possible to raise the number by 1.

5 and 6 show a third example of the device. In this example, two lift chains 16 each having a large number of hooks 15 protruding from each constituent link are installed diagonally in parallel on the trolley 3.
Furthermore, two small lift chains 17 are provided in parallel to the lower end of this lift chain 16 so that their upper ends overlap in a horizontal position. The lift chain 17 has small protrusions 18 that protrude and retract outward, and the distance between the two is about the same as the leg 1 of the chair 1.
The lift chain 1 shall be slightly smaller than a.
The mutual spacing between the numbers 6 and 6 is such that the distance between the numbers 6 and 6 goes inside the lift chain 17.

Next, the method of the present invention using this device will be explained.

To store the chair 1, one end of the trolley 3 is inserted between the legs la of the chair 1 being placed. If you do this, chair 1
The horizontal tie member 1b is hooked to one of the hooks 15 of the stationary lift chain 16.

Further, the lift chain 17 enters into the leg 1a, and a small protrusion 18 projects from its lowermost position and engages with the lower surface of the leg 1a.

After doing this, lift chain 16. 17 by one pitch at the same speed, chair 1 becomes horizontal tie member 1.
b and the lower surfaces of legs 1a are supported by hooks 15 and small protrusions 18, respectively, and rise slightly. In the same way, the next chair 1 to be stored is stacked one on top of the other with the lower side of the previous chair 1 inserted, and is supported by the next hook 15 and small protrusion 18 and raised. After that, lift the chair 1 little by little, and in that case, the upper chair 1 will be connected to the lift chain 1.
Although the support at 7 is removed, the chair 1 stacked on top of each other at the bottom supports it, so the horizontal state will not collapse.

In order to lay a large number of chairs 1 stored in a stacked state on the trolley 3 one by one, the lift chain 16
．． 17 in the opposite direction, and the chairs 1 are sequentially dropped from the trolley 3 starting from the lower part in a reverse operation to that during storage, and the chairs 1 are laid in a predetermined position.

7 to 9 show a fourth example of the device, which is the same as the third example in that a lift chain 16 is provided on the cart 3, but a guide frame 19 is inclined parallel to the lift chain 16. was installed so that its lower end was close to the floor.

The guide frames 19 are constructed as a part of the frame on the trolley 3, and two guide frames 19 are arranged in parallel, but the mutual spacing between the frames 19 and 19 is slightly larger than the distance between the legs la of the chair 1.

Next, the method of the present invention using the above-mentioned device will be explained.The chair 1 used is slightly different from the above-mentioned case. A type with an outward horizontal protrusion If formed nearby is used.

To store the installed chair 1 on the trolley 3, insert one end of the trolley 3 between the legs la of the chair 1, and
b is hooked to the hook 15 of the lift chain 16, and the horizontal protrusion 1f is engaged on the guide frame 19.

After doing this, if the lift chain 16 is rotated by one pitch, the chair 1 can be attached to the horizontal connecting member 1b using the hook 15.
, and at the same time the horizontal protrusion 1f lifts up the guide frame 19.
By sliding up the top, it can be lifted while maintaining a horizontal position.

Thereafter, in the same manner, the next chair 1 is placed under the previous chair 1 and lifted up using the next hook 15. The chairs 1 that are stored one after another are lifted up in a stacked state as described above, so they are placed on the trolley 3 in a stable state that does not easily collapse.
stored above.

On the other hand, to install chairs 1 one by one, lift chain 1
6 is rotated in the opposite direction, and the guide frame 19 is slid down one by one from the trolley 3 and laid at a predetermined position.

〔Effect of the invention〕

As described above, the automatic chair storage and installation method of the present invention is capable of automatically performing all chair installation and storage operations at a venue, and can greatly reduce the labor and time required to set up a venue. . In addition, the entire device used is lightweight and compact, so it can be easily operated by one person without damaging the floor, and it does not take up much space and can be placed in a part of the room, making it easy to store chairs. It becomes convenient. Furthermore, by arranging the devices in parallel and operating them simultaneously, it is possible to accommodate an even greater number of chairs.
