Hereinafter, a slide rail automatic closing apparatus according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in the drawings, an automatic closing apparatus for a slide rail according to an embodiment of the present invention includes a housing 20 coupled to a fixed rail provided on both inner surfaces of a drawer body and having a movable member receiving groove 21 formed on one side thereof, A moving member 30 received in the moving member receiving groove 21 of the moving member 30 and moved on the moving member receiving groove 21 and a spring 40 provided between the moving member 30 and the housing 20, And a damper (45).

The housing 20 is partially open at one side and the moving member receiving groove 21 is formed therein. Both side walls of the moving member receiving groove 21 guide the sliding movement of the moving member 30 And a spring insertion portion 2 and a damper insertion portion 22 are formed on the other side of the housing so that the spring 40 and the damper 45 are inserted along the longitudinal direction of the automatic closing device, 23 are formed.

The moving member guide hole 22 is formed with a linear movement section for horizontal movement of the moving member and a bending section connected to the linear movement section for rotating the moving member. The bending section is formed by bending at least 90 degrees in the linear movement section to prevent the moving member from being separated.

The spring insertion portion 23 is a portion where the spring is inserted, and a groove or a projection is formed at one side of the spring insertion portion to fix one end of the spring. In the present invention, it is preferable that the spring uses an elongated spring for smooth operation as well as for extending the service life.

The damper 45 is inserted into the damper inserting portion 24, and the rod end is coupled to the moving member, and the moving member is buffered while the rod is drawn or drawn in accordance with the movement of the moving member.

That is, when the drawer is retracted, the damper is restored to its original position along the linear motion section while being separated from the bending section. At this time, since the movable member is restored at high speed due to the restoring force of the spring, And is provided to mitigate the impact of the moving member.

The damper 45 normally uses a gas shock absorber.

Here, the moving member 30 of the present invention is configured to move on the moving member receiving groove 21 by being hooked on the operating member 10 provided on both side surfaces of the drawer in accordance with the draw-in and draw-out of the drawer, Unit.

Specifically, the moving member 30 has two guide projections 31 spaced from each other to be moved along the moving member guide hole 22 by being inserted into the moving member guide hole 22 on both side walls thereof, A damper engaging groove 32 is formed at the rear end of the moving member facing the damper inserting portion 24.

One of the guide protrusions 31 is a protrusion 31a moved along the linear movement section and the other is moved along the linear movement section and then moved to the bending section when the moving member is rotated, The protrusion 31b is caught in the bending section so that the member is not restored.

An elastic deformation portion 33 is formed at the front end of the moving member and an operating member engaging groove 34 is formed at an intermediate portion of the moving member adjacent to the elastic deformation portion 33 so as to be caught by the operating body 10. [ .

The elastic deformation portion 33 is formed with a deformation space 33a on the inner side and a sloped surface 33b on one side and is formed in a substantially triangular shape when viewed from the front.

The reason for forming the elastically deformed portion 33 is that the operating body is caught in the operating member catching groove 34 while pulling the drawer after mounting the first slide rail, So that the inclined surface is inserted into the actuating member retaining groove 34 while being pushed into the deforming space 33a.

In addition, even when the movable member is in the home position for various reasons during operation of the slide rail, the operating member may be pulled out from the operating member latching groove. In this case, the operating member may be artificially hooked onto the latching groove .

On the other hand, in the related art, a buffer is formed in the housing to perform this role. However, since the housing includes the moving member guide hole 22, the spring inserting portion 23, the damper inserting portion 24, and the like, the structure of the housing is complicated when the cushioning portion is formed, In case of damaging the cushion part during use, the entire housing needs to be replaced, which leads to an increase in maintenance cost. On the other hand, when the elastic member is formed in the moving member as in the present invention, the structure of the housing is simplified The strength can be improved, and the moving member can be replaced only when the elastic deforming portion is broken, so that the maintenance cost can be reduced.

Here, the support member 35 is formed on the inside of the operating member retaining groove 34 at a width smaller than the width of the elastic deforming portion to be connected to the end of the elastic deforming portion 33 to support the elastic deforming portion. The supporter 35 supports the elastically deformed portion 33 to prevent excessive deformation of the elastically deformed portion, thereby reducing the fatigue of the elastically deformed portion and preventing the elastically deformed portion from being damaged.

At this time, if the support portion 35 is equal to the width of the elastic deformation portion 33, the elastic deformation portion may not be easily deformed, and therefore, it is preferable that the width is smaller than the width of the elastic deformation portion.

On the other hand, a spring engagement portion 36 is formed to protrude from the other side of the moving member opposite to the operating member engagement groove 34 with a predetermined length facing the spring insertion portion 23.

The spring engaging portion 36 is formed at a position facing the spring inserting portion 23 in order to maintain the spring and the damper in parallel with each other.

The spring engagement portion 36 is cut from the end portion to engage with one end of the spring to form a spring engagement groove 36a.

At this time, the spring engaging portion 36 is formed to be inclined in the front end direction of the moving member so that the spring engaging portion 36a is not easily detached in a state where the spring is engaged with the spring engaging groove 36a.

In addition, it is preferable that the length of the spring engagement groove 36a is longer than the neck diameter of the spring by 1.5 times or more. The reason for this is that one end of the spring is moved on the spring engagement groove during the rotation operation of the movable member so that the spring is automatically adjusted in accordance with the operation of the movable member and can maintain the parallel state with the damper.

Therefore, as the spring and the damper are maintained in parallel, the movable member can be restored smoothly, and the fatigue of one end of the spring coupled to the movable member can be reduced, so that the breakage of the spring can be reduced.

The damper coupling groove 32 is formed so as to be perpendicular to the spring coupling groove so that the damper coupling direction is different from the coupling direction of the spring inserted into the spring coupling groove 36a, Is formed so that a flow groove 32a is formed in the same direction as the spring engagement groove 36a.

Accordingly, the rod of the damper is automatically positioned in the flow groove 32a during the turning operation of the moving member, thereby maintaining the parallel state with the spring, and damages of the damper and the damper coupling groove can be reduced.

A reinforcing protrusion 36b is formed on one surface of the spring coupling portion 36 in the tension direction of the spring coupled to the spring coupling groove 36a. The strength of the spring engagement portion 36 is increased due to the formation of the reinforcing projection, so that breakage of the spring engagement portion due to the tension of the spring can be reduced.

In the present invention, it is preferable that the damper coupling groove 32 and the spring coupling groove 36a are formed not in the same direction but in a mutually perpendicular direction. 9, the damper 45 must be coupled to the damper coupling groove 32 without moving, and the spring (not shown) 40 are coupled to the spring engagement grooves 36a so as to be moved up and down by a predetermined amount.

As described above, according to the present invention, since the movable member is formed as one unit and the structure is improved, the damper and the spring are parallel to each other, and the elastic deformation portion is formed, to be.
