JPS6039423Y2 - Pull-out handle moving door - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a door with a movable handle.

Conventionally, the opening/closing devices for relatively heavy iron doors, such as vault doors, have been either swinging or sliding doors, but regardless of which method they are, they cannot be opened from the outside when the door is opened. This was not desirable from a security perspective as the situation inside the safe could be detected.

In order to solve this inconvenience, it is possible to install a door that moves in a direction perpendicular to the entrance to the vault, but it is difficult to manually push such a door directly. However, since such doors are made of iron plates and are heavy, it is not easy to push them manually.

On the other hand, if a drive mechanism using electric power is provided, the production cost is high, it is easy to break down, and furthermore, it is inconvenient because it becomes impossible to move during a power outage.

An object of the present invention is to provide a pull-out movable door with a simple structure that can be easily moved manually.

Hereinafter, the present invention will be explained based on the illustrated embodiments.

In FIGS. 1 to 3, reference numeral 1 indicates, for example, a wall of a vault.

This wall 1 is provided with an opening 2.

A pull-out door 3 is fitted into this opening.

However, a fitting member 4 (see FIGS. 2 and 3) is fixed to each side forming the opening 2, and the edge of the back side of the door 3 fits into this fitting member 4. It looks like this.

At least two drive wheels 5 are installed on both left and right sides of the bottom of the door 3.
and a driven wheel 6 are rotatably provided by a support member 7.

The wheels 5 and 6 are movable along a pair of rails 9 embedded in the floor 8 in a direction perpendicular to the plane of the opening 2.

However, the rail 9 is made of channel material and is buried so that its open surface faces to the side, and when the wheels 5 and 6 are fitted into this channel by knowing the open surface, the wheels 5, 6. In addition, the door 3 is prevented from floating up.

A bundle 10 is rotatably supported on the front surface of the door 3 at a position where the operator can easily operate it in a standing position.

A transmission device for transmitting the drive of the bundle 10 to the drive wheels 5 is provided on the back side of the door 3.

An example of the above transmission device is shown in FIG.

In FIG. 4, a bevel gear 13 is fixed to the rear end of a support shaft 11 that is coaxial with the bundle 10.

A main shaft 12 is rotatably provided in the horizontal direction perpendicular to the shaft 11 and in the left-right direction of the door 3, and a bevel gear 14 fixed to the intermediate portion of this main shaft meshes with the bevel gear 13. As a result, the nozzle shaft 11 and the main shaft 12 are connected, and the rotational force of the nozzle shaft 11 is transmitted to the horizontal main shaft 12.

Both ends of the main shaft 12 are supported on the door 3 by bearings 15.15, and bearings 15.
, 15, a sprocket 16.16 is fixedly attached to the main shaft 12.

The drive wheels 5, 5 have coaxial sprockets 17.17.
The sprocket 16 and the sprocket 17 of the wheel 5 are fitted with a transmission edge 18, which is an endless power transmission member such as a chain.

The sprockets 17.17 are located laterally on the open sides of the channel-like tracks 9, 9, in a groove-like space formed in the floor 8.

The above transmission device is housed within a protective surface 19 and a protector 20 embedded in the door 3 (see FIGS. 1 and 3).

The upper surface and both side surfaces of the door 3 form an inclined surface that tapers toward the back surface of the door 3.

A fitting member 4 is fixed to the inner surface of the opening 2 provided in the wall 1, and is adapted to loosely fit into the inclined surface of the side surface of the door 3 when the door is closed.

Since the embodiment of the present invention is barked as described above,
In FIG. 4, when the bundle 10 is rotated in the direction of the arrow a, the main shaft 12 is rotated in the direction of the arrow A via the bevel gears 13 and 14.

Therefore, the sprocket 16 fixed to the main shaft 12 rotates the transmission edge 18, such as a chain, in the direction of arrow C to drive the drive wheel 5.
is driven in the direction of arrow d, and the door (not shown) is moved in the direction of arrow e.

Since the above transmission device is provided integrally with the door 3, the door 3 moves along the rail 9 as shown by the two-dot chain line in FIG.

FIG. 5 shows another embodiment of the transmission device.

The embodiment of FIG. 5 transfers the driving force of the bundle 10 to the drive wheels 5 without using the pair of bevel gears in the previous embodiment.
, 5.

That is, in FIG. 5, a sprocket 30 is fixed to the bundle shaft 11, and a sprocket 31 is also fixed to the horizontal main shaft 12, and these sprockets 30 and 3
1 are connected by a transmission edge 32 such as a chain.

Therefore, in the embodiment shown in FIG. 5 as well, the rotational force of the bundle 10 is
18, 17 to the drive wheels 5, which allows the door to be moved back and forth.

As a locking device for the door, a cylinder lock, a combination lock, etc. may be provided to lock the rotation of the bundle.

As described above, the pull-out bundle moving door of the present invention has a pair of channel-shaped rails buried in the floor with their open surfaces facing the sides, and the open surfaces of the pair of rails are clearly visible within each channel. Because the running wheels are installed on both the left and right sides of the bottom of the door, there is no risk of the door falling over even if no special anti-falling member is installed, and there is no risk of the door getting caught on the rails or obstructing the passage of trolleys, etc. There's nothing left to do.

The reason why such an effective bark was realized is that the power transmission mechanism first transmits the rotational force of the bundle to the horizontal shaft, and then transmits the power from both sides of the horizontal main shaft to the running wheels on both sides via the endless power floor member. This is because the bark was used to transmit information.

Further, according to the present invention, the structure is simple and the manufacturing cost is low, and heavy iron doors and the like can be easily opened and closed manually.

In addition, since the rotational force of the rotary operation bundle is once transmitted to the horizontal main shaft, and the rotational force is transmitted from both ends of this horizontal main shaft to the running wheels on both the left and right sides, the running wheels on both the left and right sides are rotationally driven at the same time. The door runs smoothly without skewing.
