Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flip-up device suitable for application mainly to a counter passage top plate.

In counters that are generally installed in a straight line, the inside (
A passageway is provided in the middle part of the counter or in the part that touches the wall to allow access between the office side (office side) and the outside (customer side), and the top plate in this passageway is separated from the other top plates and one end is pivoted. When entering or exiting, this top plate is pivoted upward to open the passage.

However, as mentioned above, in the conventional aisle top plate, one end is pivoted to the end of the fixed side top plate, and when entering or exiting, the free end is lifted up and held up by hand. It is necessary to pass through the aisle while supporting the top plate and return it to a horizontal state by hand, which makes it difficult to operate when entering and exiting.In addition, a large amount of force is required to lift the top plate and pass while supporting it. At counters in offices, shops, etc., this operation is often carried out by women and girls, so there is a problem in that it is not easy to perform this operation.

In view of this, the present invention was devised for the purpose of providing a flip-up device for a passage top board that can be opened and closed with extremely little force and that can remain stationary in the open/closed position. , a structure in which the aisle top plate is supported by a gas spring, and the waist is made to automatically flip up the aisle top plate using the expansion force of this gas spring, and also to be in a closed state using the force of the gas spring itself. It is characterized by being kept stable.

Hereinafter, the present invention will be described with reference to embodiments shown in the drawings.

The embodiment shown in the figure is a case where the counter 1 is attached to one end of an existing counter 1 to form an entry/exit passage 2 as shown in FIG.

That is, it has a side plate 3 fixed to one end face of the existing counter 1, and this side plate 3 is fixed to the counter 1 with bolts 4.

As shown in an enlarged view in FIG. 2, the base end of a passage top plate 5 is attached to the upper end of the side plate 3 by a hinge 6 so as to be able to pivot upwardly about a shaft 7 thereof.

On the other hand, a gas spring 8 is connected between the upper part of the side plate 3 and the lower surface of the free end of the passage top plate 5.

The gas spring 8 includes an outer cylinder 8a filled with gas, a piston 8b that is airtightly inserted into the outer cylinder 8a, and a rod 8C that is coupled to the piston and whose outer end projects outside the outer cylinder 8a. The rear end of the outer cylinder 8a is pivotally attached to a bracket 9 fixed to the upper end of the side plate 3 by a shaft 10, and the tip of the rod 8C is attached to a bracket 11 fixed to the lower surface of the free end of the passage top plate 5. The rod 8C is pivoted by a shaft 12, and the shaft 12, which is the pivot point of the rod 8C, pivots the shaft 7 of the hinge 6, which is the pivot of the passage top plate 5, and the outer cylinder 8a of the gas spring 8. It is located below the line A connecting each axis with the shaft 10.

Therefore, when the passage top plate 5 is closed in the horizontal position, the gas spring 8' is positioned below beyond the point of consideration, so that it biases the free end of the passage top plate 5 downward. It remains closed without flapping even when subjected to vibrations.

A stopper 13 regulates the position where the passage top plate 5 is closed in a horizontal state.

In this stopper 13, a stopper member 16 is attached to a stopper support portion 14 fixed to the lower surface of the passage top plate 5 via an adjustment bolt 15, and an elastic material 17 such as rubber is fixed to the surface of this stopper member 16. The elastic material 17 of this stopper member 16 is configured to abut against the side surface of the side plate 3.

The mounting position of the stopper member 16 is adjusted in advance by the adjustment bolt 15 so that the passage top plate 5 is in a horizontal state when the stopper member 16 comes into contact with the side plate 3.

Next, the operation of the above embodiment will be explained.

When the passage top plate 5 is placed in the horizontal closed position as shown by the solid line in FIGS. 1 and 2, the stopper member 16 comes into contact with the side surface of the side plate 3 via the elastic material 17, and the position is determined. At the same time, a line B connecting the front and rear pivots 10.12 of the gas spring 8 connects the pivot 7 of the passage top plate 5 and the gas spring 8.
Since it is located below the line A that connects the rear end pivot 10, the rod 8c can extend even if the piston 8b is pressurized by the gas pressure in the gas spring 8. As a result, the passage top plate 5 kept closed.

Next, when passing through the passage 2, if the free end of the passage top plate 5 is lifted upward, the rod 8C will be pushed in just as slightly as necessary to cross the line A connecting the shafts 7 and 10, and the passage will pass.
Thereafter, the passage top plate 5 is pivoted upward by the releasing force of the gas sealed in the outer cylinder 8a of the gas spring 8 and pressurized by the piston 8b, and when the rod 8c is fully extended, the line shown by the chain line in FIG. It will be stopped like this.

After passing, when the free end of the passage top plate 5 is pushed down, the rod 8c is pushed and the piston 8b in the outer cylinder 8a of the gas spring 8 short-circuits while compressing the gas. When the stopper member 16 comes into contact with the side surface of the side plate 3 and its position is determined, the rod 8c is pushed out a little to keep the passage top plate 5 in a stable state as described above.

In addition, if the passage top plate 5 is attached to the side plate 3 as in this embodiment, the effect that it can be used by attaching it to the side end of the existing counter 1 can be obtained.
The passage top plate 5 may be attached to the side end of the counter, and the object to be attached is not limited to the counter, but may be other fixing members.

Moreover, if a vertical swing door is attached to the passage 2,
The function as a counter can be further satisfied.

As explained above, the present invention connects the aisle top plate, which is pivotably supported upward to form the aisle at the side end of the counter, to the counter side and the free end side of the aisle top plate. Since it is configured to open and move using the gas pressure of the gas spring, there is no need to manually turn the passage top plate when entering or exiting through the passage, and there is no need to support it by hand until the passage is completed. It eliminates the hassle of time, and at the same time does not require much effort, and even women and girls can easily open and close it.

In addition, in the closed position where the aisle top plate is in a horizontal position, the force of the gas spring maintains that state, so it does not flap around and can always be kept in a stable condition. have
