Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a support mechanism for a locking device of a safe deposit box facility, and in particular, the invention relates to a support mechanism for a locking device of a safe deposit box facility. The present invention relates to a support mechanism for a locking device.

[Conventional technology]

Various systems have existed in the past for banks to allow customers to use safe deposit boxes based on individual use contracts, but one type of equipment is a system in which protective boxes (safe deposit box cases) assigned to customers are stacked in a matrix. Some items are stored in storage shelves and taken out automatically or manually each time they are used. As a storage shelf used in such equipment, for example, a shelf having a structure as shown in FIG. 4 has been used. That is, protective box A
A plurality of shelf boards B supporting the protective box B are stacked and attached to the support column C, and a notch A' for locking is formed in the lower corner of the rear end of the protective box A. A notched hole B' corresponding to the recessed portion is bored, and a locking hook D that engages with the recessed portion through the hole is pivotally supported by the rear strut C. By being locked with this locking hook D, the protection box A is always prevented from falling.When a safe deposit box is used, the locking hook D is engaged with the rod E, lever F, It may be released by the lock release actuating means H via the interlocking rod G or the like. In addition, as other locking means, locking pieces are provided on the rear end surfaces of the protective boxes stacked on the shelf board, and locking metal fittings are arranged in rows at positions corresponding to the locking pieces on the rod (vertical rod). However, there is also one that moves this rod up and down to engage and disengage the engagement fitting with the locking piece.

[Problem that the invention attempts to solve]

The storage shelf protective box locking means described above requires many complicated and specialized structural parts to be used as a locking device for safe deposit box equipment, and in order to accommodate these, large-scale construction including storage shelves and protective boxes is required. In addition, there are many types of parts such as locking hooks, rods, levers, etc., which increases the cost.Furthermore, the main parts are located on the back side of the storage shelf, making assembly and maintenance difficult. Since the structure is attached to the outside of the shelf, it occupies extra space, which is wasteful. In addition, it requires power to operate, the shock when locking and unlocking is large, and it is impossible to maintain each state unless you continue to apply force to both the locking side and the unlocking side with an electromagnetic solenoid, etc., which requires energy. In addition to consuming electricity, it was difficult to provide a fail-safe during a power outage, and there remained concerns about the reliability of all-lock operation.

Therefore, we used an all-lock lock that consists of a vertical rod that can move up and down with a locking part that locks one end of the metal fall prevention metal fitting that is installed on the front of the storage shelf, and its operating mechanism. A device was proposed, but
The following problems arose.

(a) When an eccentric cam and rollers are used as the operating mechanism, the rod (vertical rod) tends to move laterally, so precision of the axis of the drive shaft is required, which increases manufacturing costs.

(b) In either case when the vertical rod is pushed up to the locked position or lowered to the unlocked position,
This state cannot be maintained unless it is continuously energized by an electromagnetic solenoid or the like.

(c) Precision is also required in manufacturing and assembly.

(d) In order to maintain the accuracy of the shaft center, many pedestals are required, and there are concerns about the accuracy and workability of the bearing.

The present invention aims to solve the above-mentioned problems and provide a support mechanism for a locking device that is inexpensive, has excellent workability, and operates reliably.

[Means for solving problems]

As a specific means to achieve the above object, the present invention includes a fall prevention metal fitting to prevent the protective box provided on the front side of the storage shelf from falling, and a vertical fall prevention metal fitting to lock the fall prevention metal fitting in the locked position. A rod, and a drive shaft to which a cam member for moving the vertical rod up and down via a connecting plate is fixed, a loosely fitting pin is attached to the bearing of this drive shaft, and a loosely fitting pin is fitted to the connecting plate. A locking cutout is provided in which a long hole is bored to restrict the movement of the vertical rod in the lateral direction, and a plunger provided on the bearing is fitted into the shaft when the vertical rod is in the locked position. This invention proposes a support mechanism for a locking device characterized by the formation of a notch.

[Effect]

The vertical rod moves up and down by rotating a drive shaft to which a cam member is fixed, and at its top dead center position, one swingable end of the fall prevention fitting is locked at the upper protection box fall prevention position, Lock up. A loosely fitting pin attached to the bearing of the drive shaft fits into a long hole drilled in the connecting plate, and restricts movement of the vertical rod in the lateral direction.
When the vertical rod is in the locked position, the plunger is fitted into a locking notch formed in the connecting plate to maintain the locked state.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to examples and drawings.

FIG. 1 is a perspective view showing a preferred example of a locking device for a safe deposit box facility embodying the present invention. In FIG. 1, the locking device consists of a protective box holder 1 attached to a side column C in a multi-layered manner to support a protective box A.
Fall prevention fittings 1 installed on the front of 3, 13',
a vertical rod 2 attached to the side pillar C so as to be movable up and down;
It consists of an operating mechanism 3 that moves the vertical rod 2 up and down. The operating mechanism 3 includes an eccentric cam 33 which is a push-up member fixed to a drive shaft 34, and a roller portion 32 which is provided on a connecting plate 31 integral with the vertical rod 2 and moves up and down in contact with the eccentric cam 33. Consisting of The loose fitting pin 40a attached to the base plate 40 integrated with the bearing 34a of the drive shaft 34, the elongated hole 31b drilled in the connecting plate 31 and into which the loose fitting pin 40a fits, and the connecting plate 31 are in the raised position. At this time, the locking notch 31a of the connecting plate into which the plunger 36 provided on the base 40 is fitted constitutes a main part of the support mechanism of the present invention, as will be described later.

The fall prevention fitting 1 is a rod-shaped body bent at the middle, and one end is loosely fitted into the fixing hole of the protective box holder 13', and the other end is fitted into the elongated hole 11 of the other protective box holder 13. It is loosely fitted to be able to swing vertically, and is biased upward by a spring member 12. When the swingable end portion 1a moves upward, the intermediate bent portion 1b or the end portion 1a of the fall prevention fitting 1 blocks the entrance and exit path of the protective box A, thereby preventing it from falling off. Normally, the protective box A is biased by a spring to the fall prevention position. (not shown) to push down the path blocking portions 1a and 1b of the fall prevention fitting 1.

The vertical rod 2 is provided with vertically elongated elongated holes 21 corresponding to the fall prevention fittings 1 of each stage, and the elongated holes 21
When the vertical rod 2 is moved upward, the vertical rod 2
The end portion 1a of the fall prevention fitting 1 is connected to the protective box holder 1.
3. Press against the upper end of the elongated hole 21 of the fall prevention fitting 1.
is locked in the protective box fall prevention position. and,
This locked state is locked by the action of a plunger 36, which is a locking means to be described later. Therefore, when the vertical rod 2 is moved upward, even if someone enters the safe deposit box during maintenance or inspection, the locking device cannot be locked by the locking means 3.
Unless the all-lock device that is locked and unlocked in step 6 is unlocked, the vertical rod 2 cannot be lowered and the protective box A cannot be taken out.In other words, it is locked and communicates with the vertical rod. All storage shelves will be locked.

The operating mechanism 3 is a mechanism that moves the vertical rod 2 up and down, and FIG. 2 is a perspective view showing in detail an example of the operating mechanism used in the present invention. In FIG. 2, the operating mechanism includes a connecting plate 31 that moves vertically together with the vertical rod 2, and a roller section 3 attached to the connecting plate 31.
2, and an eccentric cam 3 that pushes up the vertical rod 2 to the locked position via the connecting plate 31 and the roller portion 32.
3, and a drive shaft 34 on which the eccentric cam 33 is mounted.
and a motor 35 that rotates the drive shaft 34, a plunger 36 that fits into the locking notch 31a of the connecting plate 31 at the position where the vertical rod 2 has moved upward, and a plunger 36 that is attached in the direction of the notch 31a. an elastic member 37 that urges the elastic member 37; a lock releasing means 38 that pulls out the plunger 36 from the notch 31a against the urging of the elastic member 37; It consists of a lower end stop position adjustment mechanism 39 provided at the lower end of the vertical rod 2 so as to maintain a desired gap between it and the eccentric cam 33. In the above mechanism, when the motor 35 rotates the drive shaft 34, the long diameter edge of the eccentric cam 33 faces upward, contacts the roller portion 32, and pushes the vertical rod 2 up to the locking position via the connecting plate 31. . At that position, the plunger 36 is urged by the elastic member 37 and the connecting plate 3
Even if the long diameter edge of the eccentric cam 33 rotates downward and returns to the released state, the connecting plate 31 remains in the upper position and the vertical rod 2 is held in the locked position. . With the conventional protection box locking means shown in FIG. 4, the state could not be maintained unless the locking side and the release side were continuously energized by an electromagnetic solenoid, etc., but the operation of this embodiment According to the mechanism, once the vertical rod 2 is pushed up to the locked position, it is locked by the plunger 36 and the locked state is maintained, so there is no need to worry about continued consumption of energy.
The lock is released when the plunger 36 is pulled out by the lock release means 38, the vertical rod 2 is lowered, and the oar lock device is unlocked. The unlocking means 38 is equipped with both an electromagnetic solenoid and a manual lever, and can be manually unlocked using a key in the event of a power outage. can be operated under normal conditions.

FIGS. 3A and 3B are side views showing an example of the support mechanism of a locking device embodying the present invention. FIG. 3A shows the locked state, and FIG. 3B shows the unlocked state. In both figures, a connecting plate 31 is fixed to the lower end of the vertical rod 2, and a roller portion 32 is attached to the connecting plate 31. As already explained, the locking device of the present invention is locked and unlocked by moving the vertical rod 2 up and down. At the position where the connecting plate 31 is pushed up, the notch 31a of the connecting plate 31
A plunger 36, which is a locking means, is inserted into the
As shown in Figure A, the connecting plate 31 and the vertical rod 2 are locked. This plunger 36 can be pulled out to the right in the drawing by a lock release means such as a solenoid 38b or a manual key 38d, and the unlocked connecting plate 31 and vertical rod 2 can be lowered. At this time, unless the downward direction of the connecting plate 31 is always stable and the contact between the roller part 32 and the eccentric cam 33 is not made in the correct corresponding position, failure is likely to occur, and of course, the drive shaft of the eccentric cam 33 The desired correspondence relationship cannot be maintained unless the precision of the shaft center of 34 and the workability of its bearing are stable. Therefore, in the present invention, as shown in FIG. 3, the substrate 40 is fixed to the bearing 34a of the drive shaft 34, and on the other hand, a vertically elongated elongated hole 31b is bored in the connecting plate 31, A loosely fitting pin 40a from the substrate 40 is inserted into the elongated hole 31b.
By fitting them together, the movement of the connecting plate 31, that is, the vertical rod 2, in the lateral direction is restricted. Since the loose fitting pin 40a is fixed to the base plate 40, the vertical movement of the connecting plate 31 is limited to the shape and dimensions of the elongated hole 31b, and the upper part is in the locked position shown in FIG. 3A, and the lower part is in the locked position. It will be in the unlocked position shown in Figure 3B.
Of course, this is one condition of the operating limit, and the stroke of the connecting plate 31 is also determined by the shape and dimensions of the eccentric cam 33, and furthermore, by providing a stopper at the lower end of the vertical rod. is also restricted. However, in any case, the movement in the horizontal direction is determined by the correspondence between the elongated hole 31b and the loose fitting pin 40a, and naturally the correspondence in the horizontal direction between the roller portion 32 and the eccentric cam 33 is also stable, and the vibration is stable. etc. will disappear. Furthermore, in the present invention, the plunger 36 as a means for locking the connecting plate 31, and the solenoid 38b and manual key 38d as means for releasing the lock are also attached to the base plate 40, so that the operating mechanism and the support mechanism are integrally constructed. It has a sturdy structure. Also,
Since the bearing 34a is only subjected to the drag force of the rollers from above, it can be a simple one such as a U-shaped groove as shown in this embodiment, and has the advantage of being easy to assemble and adjust. It is also possible to use a type that allows you to insert it. In addition, in this example,
Although the coupling plate 31 and the bearing 34a are connected by the loosely fitting pin through the substrate 40, a structure may be adopted in which the loosely fitting pin is attached to a part of the bearing itself.

The above mechanism is configured for each vertical rod and operating mechanism at the intermediate portion of the drive shaft 34 of the eccentric cam 33, and the bearing 3
4a are each stabilized, it is sufficient for the drive shaft itself to be pivotally supported at both ends by simple pillow blocks, etc., and great precision during manufacture is not required.

[Effect of idea]

As described above, according to the present invention, it is possible to provide a support mechanism for a locking device that is easy to adjust, has good workability, is inexpensive, and operates reliably, and has the following effects.

(a) It can be assembled and maintained from the front, the locking device works reliably, and the manufacturing cost is low.

Only when the vertical rod is pushed up to the locked position does the plunger engage the locking notch in the connecting plate.
Since it is pushed in by the elastic member, energy loss is extremely small.

(b) Since it is only necessary to adjust the push-up member and the abutment member, the accuracy of the axis of the drive shaft is not necessary.
Easy to manufacture and assemble.

(c) Since there is no need to achieve axial accuracy of the drive shaft, it can be manufactured at low cost.

(d) Since the bearing is incorporated into the locking device unit, workability is good.

(e) Since both ends of the drive shaft are simply supported by pillow blocks, equipment costs can be reduced.
