Description

Detailed Description of the Invention

[0001]

This invention relates to bathing facilities such as public baths,
Regarding metal lockers installed in sports facilities,
In particular, the present invention relates to a locker having an outset structure in which the door body is attached to the outside of the storage portion of the locker body.

[0002]

2. Description of the Related Art A locker having an outset structure in which a door body is attached to the outside of a storage portion of a locker body has a door stopper rubber 9 attached to the door body. There is a little gap.

A locker having an outset structure generally has a longer distance between the lock 3 and the barbed fitting hole 5 than a locker having a door fitted so as to fit in the opening of the storage portion of the locker body 1. The length of the barb piece 4 is also long.

Therefore, when the tip of the tool B such as a burl is put in the gap between the locker body 1 and the door body 2 to pry open the door body 2, the barb pieces 4 are bent and deformed as shown in FIG. ,
Since the lock 3 is broken and the door 2 is opened, there is a problem that it is easy to be stolen.

Therefore, the bar bar 4 is made thicker to make it hard to bend, or the tip of the bar bar 4 is formed in a hook shape to prevent theft by prying, but a door using a tool such as a bar is used. I couldn't stand the theft of breaking open.

[0006]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a locker which can improve the rigidity of the door body against prying by adding parts having a simple structure.

[0007]

Therefore, according to the present invention, a door body 2 formed by bending a metal plate is attached to a locker body 1 having a front open storage portion so as to be openable and closable outside the storage portion. A locker in which a lock 3 that can be locked by inserting a barb piece 4 into a barb piece insertion hole 5 formed on the inner surface of the opening of the storage part is attached to the door body 2, and the lock piece is fitted into the locker body 1. A reinforcing metal fitting 6 having an elongated barb piece passing hole 6d through which the barb 4 can pass is attached to the inner surface of the door body 2 at a position corresponding to the hole 5.

When the door body 2 of the locker of the present invention is pry open with a tool such as a bar, the door body 2 bends, and the reinforcing metal fitting 6 attached to the door body 2 falls down on the side of the lock bar main body 1 into which the bar bar is fitted and the bar bar. The one-side insertion hole 5 and the bar-bar passage hole 6d of the reinforcing metal member 6 come close to each other. Therefore, when the door body 2 is pry open with a tool such as a burl, the barb pieces 4 are not subjected to bending force but to shearing force, and the barb pieces 4 are less likely to be broken.

The door body 2 is formed by forming a bent portion 2a bent in a U shape at the outer peripheral end portion, and further engages the reinforcing metal fitting 6 with the bent portion 2a at the outer peripheral end portion of the door body 2. It is preferable to provide the claw pieces 6c, 6c.

With this arrangement, when the door body 2 is pryed open by a tool such as a bar, a pulling force is applied to the mounting portion of the reinforcing metal fitting 6 with the door body 2, but the claw of the reinforcing metal fitting 6 is applied. Since the pieces 6c, 6c are engaged with the U-shaped bent portion 2a of the door body 2, the pulling force applied to the attachment portion between the reinforcing metal fitting 6 and the door body 2 is weakened.

[0011]

DETAILED DESCRIPTION OF THE INVENTION The structure of the locker of the present invention will be described below with reference to the drawings of FIGS. In addition, in this embodiment, a locker for a large number of people, in which storage units are provided on the upper, lower, left and right sides, will be described, but a locker for one person to several people can be used.

FIG. 1 is a perspective view of a locker of the present invention. In the figure, reference numeral 1 is a box-shaped metal locker main body 1 having an open front, and the inside of the locker main body 1 is divided into a plurality of sections. Is formed. Each of the storage parts is provided with a door body 2 which is openably and closably attached by an offset hinge (not shown).

Therefore, the door body 2 covers each of the storage parts from the outside thereof.

Further, a lock 3 is attached to the door body 2, and the lock piece 3 of the lock 3 is locked / unlocked by fitting / removing into / from the lock piece fitting hole 5 of the locker body 1. .

FIG. 2 is an exploded perspective view of the door body 2 as seen from the inside, and the structure of the door body 2 will be described in detail.

The door body 2 is formed by bending a thin metal plate, and has a bent portion 2a bent in a U-shape at the outer peripheral end, and the door portion 2 is formed by the bent portion 2a. In addition to having a thickness, the rigidity of the door body 2 is enhanced. Further, the bent portion 2a on the open end side opposite to the hinge of the door body 2 is provided with an inner bent portion 2c bent further inward so as to avoid the interference between the steel plate cutting surface and the user's body. It has become. In the inner bent portion 2c, slits 2b, 2b into which a claw piece 6c of a reinforcing metal fitting 6 to be described later can be inserted are formed vertically. Further, the door body 2 is formed with a lock hole 7 for attaching the lock 3.

The lock 3 has a well-known structure in which a sickle-shaped barb piece 4 rotates as a key is inserted into a keyhole and rotated.
The barb pieces 4 are in an upward position when unlocked, and the barb pieces 4 are in a lateral position when locked.

The inner surface of the door body 2 is closer to the open end side (the door body 2
At the position close to the barb fitting hole 5 between the barb fitting hole 5 and the lock 3 when the is closed), the reinforcing metal fitting 6 is attached by welding the leg portions 6a, 6a by spot welding.

The reinforcing metal fitting 6 has two legs 6a, 6a in contact with the inner surface of the door body 2 and a main body of the reinforcing metal fitting having a size capable of protecting the lock 3 extending in a direction orthogonal to the inner surface of the door body 2. 6b,
It is composed of two claw pieces 6c, 6c extending from the upper and lower ends of the reinforcing metal body part 6b to the open end side of the door body 2, and at the position corresponding to the barbed piece fitting hole 5 of the reinforcing metal body part 6b when the door is closed, the bar bar piece. Through hole 6d
Are formed. It is preferable that the barb passage holes 6d have the minimum width and length through which the barb 4 can pass. The two claw pieces 6c, 6c of the reinforcing metal member 6 are shaped so as to pass through the slits 2b, 2b of the door body 2 and just fit into the bent portion 2a.

FIG. 3 is a cross-sectional view seen from a plane side showing a state in which the door body 2 is closed and the lock 3 is locked.

As shown in the drawing, a gap L is provided between the rocker body 1 and the reinforcing metal fitting 6 in order to prevent interference with the rocker body 1 when the door body 2 is opened and closed. Further, the tip of the barb piece 4 passes through the barb piece passing hole 6d and is fitted into and removed from the barb piece fitting hole 5.

A small gap is formed between the locker body 1 and the door body 2 by the contact rubber 9.

In this locked state, a tool B such as a bar
When is inserted between the locker body 1 and the door body 2, the tip of the tool B hits the reinforcing metal fitting 6 and is prevented from being pushed deeply, making it difficult to pry open.

If the door body 2 is opened in this state, the open end side of the door body 2 is bent toward the front side (downward in FIG. 4, as shown in FIG. 4) and deformed as shown in FIG. At this time, the reinforcing metal fitting 6
Since the leg portions 6a are welded to the door body 2, as the door body 2 bends, the reinforcing metal fitting 6 leans toward the bar bar insertion hole 5 side, and the gap L between the rocker body 1 and the reinforcing metal fitting 6 becomes narrower.
Therefore, the barb pieces 4 are subjected to shearing force instead of bending force, and the barb pieces 4 are less likely to be broken.

At this time, a force (an upward force in FIG. 4) for peeling off the spot welding of the legs 6a, 6a of the reinforcing metal fitting 6 is applied, but the claw pieces 6c, 6c are slits 2b of the door body 2. ，
Since it enters into the bent portion 2a through the space between 2b and is caught by the bent portion 2a, the force applied to the spot welded portions of the leg portions 6a, 6a is weakened. Therefore, the reinforcing metal fitting 6
The spot welded portions of the legs 6a, 6a of the are difficult to come off from the door body 2.

As described above, the locker of the present invention has a rigidity higher than that of the conventional locker when the door body is pry open by a tool such as a bar.

[0027]

As described above, in the locker of the present invention, the barb pieces 4 are less likely to be broken, and the rigidity against the prying of the door body is improved, and the locker has an excellent antitheft effect. Is. Further, in the locker of the present invention, since only one component is added to the conventional locker, there is also an effect that the cost increase can be reduced.

Further, as in the invention described in claim 2, the door body 2 is one in which a bent portion 2a bent in a U-shape is formed at the outer peripheral end portion, and the reinforcing metal fitting 6 is further provided with a door body. If claw pieces 6c, 6c that engage with the bent portion 2a of the outer peripheral end of 2 are provided, when the door body 2 is pryed open by a tool such as a bar, the reinforcing metal fitting 6 is attached to the door body 2. Although the pulling force is applied to the portion, since the claw pieces 6c, 6c of the reinforcing metal fitting 6 are engaged with the U-shaped bent portion 2a of the door body 2, the reinforcing metal fitting 6
The tensile force applied to the attachment part between the door and the door 2 is weakened,
Furthermore, the rigidity of the door body against prying open is improved.
