Description

[Detailed explanation of the idea] This invention relates to an electric sliding fireproof storage.

As this type of sliding fireproof storage, there has been known a sliding fireproof storage as seen in Japanese Utility Model Publication No. 54315/1983, which was developed by the applicant of the present invention.

This device has a pair of casings that are open on only one side and is arranged with their openings facing each other, and is movable so that both casings can be joined and separated. In order to fasten and fix the bodies in a joined state, a running handle and a tightening handle are provided protruding from the side of one of the casings, and by rotation or rotation of these handles, the casing is moved. The movement and tightening operation are performed in a state where both the casings are joined.

By the way, this type of sliding fireproof safe has a large opening and takes up less installation space compared to conventional fireproof safes with doors that open and close, considering its internal volume. In recent years, larger sizes have come into use.

However, moving or manually tightening such a sliding fireproof warehouse requires an extremely large amount of human power. The present inventors have also proposed that the tightening operation can be performed by remote control using an electric motor as a drive source.

However, in the event of a power outage or other unforeseen circumstances, these electrically powered traveling and tightening operations become completely ineffective, so these operations can be switched to manual operation. It is necessary to do so.

The present invention was developed in view of the above-mentioned background, and it is designed to switch between electric driving, tightening operation when connecting the casings, and the above-mentioned manual operation by switching the clutch. The purpose is to make the mechanism extremely simple.

Hereinafter, one embodiment of this invention will be described in detail based on the drawings.

FIG. 3 shows details of the drive mechanism, which consists of a running drive motor 8 and a tightening drive motor 9 arranged and fixed on both sides of the handle shaft 7a of the handle 7, which is located approximately in the center. It is equipped with

The traveling drive motor 8 has an output shaft 8c connected to its tip via a reducer 8a and an electromagnetic clutch 8b.
is provided protrudingly, and this output shaft 8c is pivotally supported by a bearing bracket 10, and is also axially installed perpendicularly to the axial direction of this output shaft 8c via bevel gears 11 and 12 provided at the tip thereof. The output is transmitted to the intermediate shaft 13.

A sprocket 14 is mounted on the intermediate shaft 13, and this sprocket 14 is connected via a chain 16a to a second sprocket 15 provided at the lower part of the intermediate shaft 13, that is, at the same position as the wheel 4, as shown in FIG. Although the second sprocket 15 is not shown, the same sprocket is provided coaxially with the second sprocket 15, and this sprocket 15 is connected to the sprocket coaxially with the wheel 4 via a chain 16b. Accordingly, the rotational power of the motor 8 rotates the wheels 4, thereby making it possible to move the housing 3 along the running rail 1.

Also, like the traveling drive motor 8, the tightening drive motor 9 has an output shaft 9c connected to its tip via a reducer 9a and an electromagnetic clutch 9b.
A bevel gear 19 is mounted on the protruding end of the bearing bracket 18 and is coaxial with the handle shaft 7a perpendicular to the bevel gear 19. It meshes with a bevel gear 20a provided on the intermediate shaft 20.

This intermediate shaft 20 passes through the fireproof storage main body 3a, and has its tip protruding into the interior panel 3c, and a pinion 21 is mounted on this protruding end.
is meshed with a large-diameter gear 22 that is mounted and protruded from the inner surface of the fireproof storage main body 30, thereby further slowing down the rotation of the intermediate shaft 20 and increasing the torque.

A pair of sprockets 23, 23 are integrally mounted on the tip of this large-diameter gear 22, and each of these sprockets 23 connects to a drive sprocket 24 provided above and below the side edge of the opening 3b of the housing 3, respectively. , 24 via chains 25, 25 (see FIG. 1).

The structure of the tightening mechanism in this part is shown in FIGS. 4 and 5.

In the figure, 26 is a gear mounted on the same axis as the sprocket 24, and 28 is this gear 2.
6, which rotates by meshing with gear 2.
Reference numeral 8 is provided at one end of a shaft 29 extending along the width direction of the housing 3 .

Locking pins 30 are provided at both ends of this shaft 29.
A disk 30 with a portion a protruding eccentrically is provided integrally.

On the other hand, on both inner walls of the opening of the casing 2, a fifth
As shown in the figure, a cam block 31 is formed,
The end surface of this cam block 31 is connected to the locking pin 3.
A cam groove 31a is formed facing the locking pin 30a and extending along the rotational direction of the locking pin 30a.

Therefore, if the drive motor 9 is driven to rotate and the tightening shaft 29 is rotated, the locking pin 30 is rotated.
a enters into the cam groove 31a along the cam groove 31a, and in a state where the casings 2 and 3 are joined, the two are firmly fastened while pressing the joint part.

In addition, the casings 2 and 3 are fastened with the same structure on the lower side, and thereby the upper, lower, left and right 4
Both openings are closed simultaneously at both locations with uniform fastening force.

The locking mechanism using the combination lock 6 in this fastened state is clearly seen in FIG.

This device includes a dial shaft 32 connected to the dial lock 6 and protruding from the inner surface of the fireproof storage main body 3a, a conversion mechanism 33 for sliding the rotation of the dial shaft 32 orthogonally to this shaft, and a conversion mechanism 33 for sliding the rotation of the dial shaft 32 orthogonally to this axis. At the tip of the mechanism 33, the large diameter gear 2
The lock lever 34 is provided with a lock lever 34 that protrudes freely into and out of a locking groove 22a formed in a part of the dial 2, and when the respective dials 6 are rotated to match the signs, the lock lever 34 is engaged from the position shown in the figure. When it comes out of the stopper groove 22a, the lock is released.

Next, the clutch mechanism of the handle 7 will be explained.

The handle shaft 7a of the handle is cylindrical, and the end of the intermediate shaft 20 is fitted into the end of the handle shaft 7a that projects into the exterior panel 3b. A clutch gear 4 is attached to the handle shaft 7a.
A front friction clutch 41 is integrally connected to the tip of the clutch gear 40 and faces a front friction clutch 42 formed at the end of the intermediate shaft 20.

Further, the clutch gear 40 and a clutch gear 43 adjacent to the clutch gear 40 are integrally mounted on the intermediate shaft 13 for traveling.

In FIG. 3, the clutch gear 40 and the front friction clutch 41 are connected to each intermediate shaft 1.
The friction clutches 42 and clutch gears 43 provided at 3 and 20 are in a separated state, that is, both clutches are in a disengaged state.

That is, in this state, the casing 3 alone or together with the casing 2 can automatically travel by the drive motor 8, and can also be unfastened or tightened by the rotation of the motor 9. ing.

Further, for example, by stopping the travel drive motor 8 and operating the handle 7, the housing 3 or the housings 2 and 3 can be moved.
When you want to run the handle, pull the handle 7 toward you to move the handle shaft 7a, and engage the clutch gear 40 with the clutch gear 43 mounted on the intermediate shaft 13. It is now possible to travel by rotating the wheel at step 7. In this case, the electromagnetic clutch 8b of the motor 8 is disengaged, and the housing 3 can be moved only by rotating the handle 7.

Next, when it is desired to engage and disengage the tightening mechanism by operating the handle, press the handle 7 to move the handle shaft 7a and engage the front friction clutches 41 and 42 with each other. The shaft 7a is directly coupled to the intermediate shaft 20, and the tightening mechanism can be tightened or released via this shaft.

In this case as well, the electromagnetic clutch 9b is in a disengaged state because the motor 9 is not activated.

The neutral position of the handle shaft and the sliding operation of the handle shaft 7 for coupling the driving mechanism to the traveling mechanism or coupling the tightening mechanism to the drive system can be performed, for example, via a link mechanism. , and it goes without saying that the operating lever of this link mechanism can be provided to protrude toward the front of the exterior panel 3b.

In addition, when both casings of the sliding fireproof storage are tightened via the tightening mechanism, the clutch of the handle shaft is placed on the tightening mechanism side, and when the tightened condition is released, the clutch is placed on the traveling side. Furthermore, it is also possible to automatically set it to an intermediate position by external remote control, etc., in a state where it is in a mode in which running, tightening, and release are performed via each drive motor. .

As explained in detail in the embodiments above, in the electric sliding fireproof storage according to the invention, a motor for traveling and a motor for driving the rotation of the tightening shaft are provided in the casing constituting the sliding fireproof storage. It is possible to automatically travel, tighten and release the tightening through the handlebar, and if necessary, it is also possible to travel or tighten and release the tightening by operating the manual handle as necessary, so it is especially useful during power outages or other emergencies. This eliminates the inconveniences caused by switching to an electric type.

In addition, during manual operation, it can be used for traveling or for tightening between the two casings by switching one handle and clutch, so the mechanism required for electric and manual switching is extremely simplified. Therefore, it has various advantages such as being able to house these mechanical parts compactly within the housing.
