Description

{HINGE FOR PRIVATE BOX}

In everyday life, we often use lockers or lockers (lockers, lockers, lockers for temporary storage of school supplies or supplies, lockers or lockers for storing personal belongings in underground shops, The storage compartment is provided with a locker door with a lock on the front of the compartment and is installed in most multi-stage form for the majority use.

However, when a locker door is closed, the locker may be slightly different, but the door may open slightly or the door may be closed more or less at any moment.

If the door is closed or opened arbitrarily, there is a fear that the body of the passer who passes in front of the locker may be caught or bumped on the opened door, and the inside of the chamber is exposed to the outside, Can occur.

To solve this problem, a locker having a door closing function for keeping the locker door in a closed state has been proposed. For example, there is a registered utility model 20-0176179, registered utility model 20-0449640, etc. , And further proposed Patent Registration No. 1010096110000 proposed by the present inventor to solve the problems of the above two inventions.

However, in the case of the above-mentioned Patent No. 1010096110000 proposed by the present inventor, there is a problem that the elastic closing piece (refer to FIG. 9) which is heat-treated so as to have elasticity is broken well and the door closing maintaining function is not maintained frequently.

The reason why the elastic piece is broken is that the elastic body 140 of the hinge 100 is installed between the fixed bracket 100a and the rotary bracket 120 as shown in FIG. 143 are easily squeezed and the resilience inherent to the elastic pieces 143 due to the squeezing of the elastic pieces 143 is weakened or lost.

Since the elastic member 143 is manufactured by heat treating the metal material, if the heat treatment is inappropriate, the elastic force is weak and the door closing function is weakened. On the contrary, when the elastic member 143 is excessively broken, 143 are required to be heat-treated, so that it is difficult to manufacture and the manufacturing cost is increased. In particular, the reliability of the hinge operation is deteriorated.

One of the solutions to the above problem is to increase the thickness of the elastic member so as not to break the elastic piece. However, when the thickness of the elastic piece increases, the space between the fixed bracket 100a and the rotary bracket 120 becomes large, not.

In addition, when the elastic body 140 is replaced, the locking protrusion 142 and the locking ring 144 provided in the elastic body are easily broken and become defective as described above in the manufacturing process. Further, when the elastic body 140 is replaced, The elastic bracket 120 and the fixing bracket 100a are separated from each other so that the elastic body can be replaced.

In this case, since the door 1a of the locker is first separated from the rotary bracket 120 (the bolt is loosened) and then the hinge pin 130 is removed, the elastic body can be replaced, so that the replacement of the elastic body is inconvenient and troublesome. For further details, reference may be made to Korean Patent No. 1010096110000.

The present invention has been made to solve the problems of the above-mentioned Patent No. 1010096110000, and the present invention has been accomplished with the present invention.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a hinge for a locker having a door closing and holding device for reliably securing the reliability of the door closing function of the hinge for a locker and improving the durability of the elastic body .

It is another object of the present invention to provide a hinge for a locker having a door closing and holding device that facilitates assembly and repair of a locker hinge.

It is another object of the present invention to provide a hinge for a locker with a door closing maintenance device which reduces manufacturing cost of a locker hinge and improves durability.

In order to solve the main object of the present invention,

The hinge pin is used to pivotally connect the resilient body having elasticity with the supporting plate of the fixing bracket and the supporting plate and the projection of the rotating bracket so that the protrusion of the plate body passes through the supporting plate and is positioned at the through hole of the rotating bracket It is characterized by its implementation by installing.

Since the projections located in the through holes are elastically corresponding to each other in the through hole when the door is opened and closed, the door closing state can be clearly maintained without interfering with the opening and closing operation of the door.

According to another aspect of the present invention,

The supporting plate of the rotary bracket fixed to the inner side surface of the door is fixed to the supporting plate of the fixing bracket fixed to the upper and lower side inner walls of the chamber when the hinge is assembled to be rotatable through the hinge pin, And the elastic body is coupled to the support plate through the hinge pin on the back surface so that the elastic body can be easily replaced when the door is not detached from the rotary bracket during the replacement of the elastic body and only the hinge pin is detached.

Means for solving the other object of the present invention is characterized in that,

The above-described fixed bracket, the rotating bracket and the elastic body can be integrally combined with the hinge pin to realize the hinge for the single-type locker, and the pair of the double-hinged door hinge can be symmetrically joined to each other by using the longer hinge pin. It is characterized by its dual type hinge.

The elastic body of the present invention is characterized in that the body having a certain length is configured to have an elastic shape in the shape of an arch or a body.

Since the elastic body is not coupled between the brackets but is coupled to the outside of the support plate, the elasticity of the elastic body is not lost (uncompressed) during the opening and closing operation of the door, and when the door is closed, the protrusion of the elastic body passes through the support plate And is positioned in the through hole of the support plate, so that the closed state of the door can be reliably maintained.

Further, since the elastic plate of the present invention is assembled together with the support plate of the rotation bracket and the support plate of the fixing bracket via the hinge pin when pivotably assembled, the assembly is easy.

Further, in the hinge of the present invention, when the elastic body is replaced during use, since the elastic body can be directly replaced without removing the locker door from the rotary bracket by removing the hinge pin, the hinge repairing operation becomes easy and convenient.

Further, since the elastic body of the present invention is formed in an arc shape or a bent shape and has elasticity, a skilled heat treatment technique is not required and it is not necessary to equip the elastic piece, the latching jaw and the hooking ring like the conventional elastic body, The manufacturing cost is reduced, and the manufacturing is facilitated.
