Description

[0001] DAMPING APPARATUS FOR SLIDER [0002]

The present invention enables the adoption of a pneumatic damper of a relatively large size so as to maintain the cleanliness of the buffer around the shock absorber without worrying about leakage, maximize the life span of the shock absorber without sacrificing the trouble, reduce the manufacturing cost by reducing the cost, And more particularly, to a slider shock absorber having a damper housing portion for simplifying the structure.

2. Description of the Related Art Generally, a drawer of a sliding door or a drawer of furniture is provided with a roller device which is guided by a door frame or a rail provided on a furniture body to slide and move, thereby achieving a smooth opening and closing operation with less force.

 Such a sliding door or a drawer (hereinafter referred to as a "slider") smoothly slides and moves while opening and closing the sliding door. In particular, the sliding door or the sliding door collides against the door frame or the drawer body due to self weight and sliding inertia during closing operation, And various research and development have been carried out to solve this problem.

As an alternative to this problem, separate shock absorbers disclosed in Patent Registration No. 10-1180141 (August 30, 2012) (hereinafter referred to as "Prior Art") are used.

As shown in FIG. 1, the prior art includes a case 110a, 110b for guiding the movement of the hook 150 and receiving the damper 130, a damper 130 to which the hook 150 is mounted at the tip, And a tension spring 170 for returning the spring 150.

In such a shock absorber, a latch fixed to the slider is fitted in the hook 150, so that the closing operation of the slider is buffered by the damper 130. [

In the closed state of the slider, the length of the rod withdrawing length of the damper 130 and the length of the tension spring 170 are shortest when the latch is fitted in the hook 150. When the slider starts to be opened, And the rod of the damper 130 to which the hook is fixed move together and the tension spring 170 is stretched.

The hook 150 is guided and guided in the guide groove 111 formed in the case to allow the release of the latch so that the latch is released from the buffer and the slider So that the hook 150 is kept in a rotated state by the guide groove 111. [

This can be achieved by forming the guide groove formed in the case to bend to one side from the forward end of the straight section (see Fig. 4).

In addition, when the slider in the open state is moved, the slider is moved to return to the movable state by pushing the hook 150 in the rotated state while the slider is moving, so that the latch is engaged with the hook, And the slider is restored to the slow speed by the restoring force of the tension spring 170 to prevent the slider from colliding with the door frame or the drawer body.

In such a slider damping device, the damping force of the damper is very important. However, it is difficult to increase the size of the case and the damper receiving portion due to the limitation on the space to be installed, thereby limiting the diameter of the damper to determine the damping force.

2, the damper receiving portion of the case 110 is configured to surround four or three sides of the damper body 130 of the cylindrical body, A hydraulic damper is adopted which can expect a larger damping force in comparison with a pneumatic damper in the case of the same diameter because the space of the damper housing part becomes smaller.

However, in the case of a hydraulic damper, there is a problem in that the oil leakage occurs due to the lapse of time, and the periphery is contaminated dirty, the structure is complicated and there is a risk of failure, and the structure is complicated and the cost is increased.

The reason why the hydraulic damper is adopted in the prior arts despite these problems is that the size of the damper housing space directly connected to the diameter of the damper 130 in the case is small as described above, It does not have sufficient damping force.

In addition, as shown in FIGS. 1 and 2, when the body is divided into two members 110a and 110b, the case 110, which surrounds the cylindrical damper on four or three sides as described above, It is easy to take out the mold from the mold at the time of manufacturing, but the number of molds and parts is increased, and the number of assembling holes is increased, so that the productivity is lowered.

For this reason, in recent years, it is a general trend that the case is molded by molding into a single body in which the damper is surrounded on three sides.

However, in the case of the integral type case in which the cylindrical damper is surrounded on three sides, the undercut must be taken out, so that the structure of the mold becomes very complicated.

The mold for integrally formed case must have a structure in which the undercut core is divided into a plurality of parts and sequentially removed so that not only the mold cost but also the breakdown frequently occurs and the life is extremely shortened.

Meanwhile, in the prior art, when the hook is formed as a single body, the hook mounted on the slider can not be inserted into the hook when the hook is located in the straight section which is reciprocable in the guide groove of the case.

Accordingly, when the slider is installed, it is necessary to assemble the hanger in a state that the hanger is inserted into the hook, thereby complicating installation and assembling work, which may waste time and labor and make the worker difficult.

In addition, when the hook 150 is rotated and the hook 150, which has been in a rotating state after exiting the shock absorber, collapses into the straight section of the guide groove while leaving the position for some reason such as an external impact, There is a problem that the slider can not be completely closed because the slider can not enter into the hook.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a slider shock absorber in which a damper housing portion of the present invention is extended will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 3 to 9, the slider shock absorber 1 having the damper housing part according to the present invention is provided with a guide groove 11 for guiding the movement of the hook, which is fixed to a fixed body including a door frame of a sliding door, A damper 30 mounted on the damper housing portion 13 of the case 10 and a damper 30 mounted on the tip of the rod 33 of the damper, A hook 50 into which the latch 2 fixed to the slider is inserted and a tension spring 70 fixed to the hook 50 at one end and fixed to the case 10 at the other end for returning the damper 30. [ And the case 10 is formed such that both directions opposed to the damper housing part 13 are opened.

The case 10 includes a lower support surface 132 formed between the damper accommodating space and the tension spring 70 and an upper support surface 131 formed on the lower support surface 132, The damper housing portion 13 is formed by the upper portion 135 and the lower portion support surface 131. At least one support ridge 133 and 133a for supporting the damper 30 are formed on the upper support surface 131 and the lower support surface 132, .

The support protrusions 133 and 133a are curved in correspondence with the radius of the cylindrical damper main body 31 and are disposed alternately with respect to the centers of the upper support surface 131 and the lower support surface 132 (See Figs. 3, 4, and 6 to 9).

The supporting ridges 133 and 133a are formed in such a manner that the curved portion 133r starts from the upper supporting surface 131 and the lower supporting surface 132 and cooperates with the supporting ridges 133 and 133a, And the lower part.

The support protrusions 133 and 133a may be arranged symmetrically with respect to the upper support surface 131 and the lower support surface 132 (see FIG. 9).

As described above, the supporting ridges 133 (133a) are opposed to each other at the upper and lower portions, so that a more rigid supporting force can be obtained.

In addition, the upper support surface 131 may have a thickness 131t that is thinner than the thickness 132t of the lower support surface (see FIG. 10).

In addition, the support protrusion 133a of the support protrusion 133a may have a larger protruding dimension than the support protrusion 133 of the damper insertion port 132 (see FIG. 9).

As described above, the damper housing portion 13 of the case installed in the limited space supports the damper 30 only in the upper and lower directions. In this way, the size of the damper housing space is significantly increased So that it is possible to accommodate the damper main body 31 having a diameter of about 3 mm or more.

Considering that the diameter of the existing damper is usually 8 mm or less, the diameter of the damper is increased by about 3 mm or more, and thus the damper capacity is greatly expanded compared with the prior art.

Accordingly, in the present invention, it is possible to install a damper of a relatively large size and adopt a pneumatic damper.

In other words, the pneumatic damper is separated from the hydraulic damper in the case of the same diameter in the damping force of the damper 30. However, according to the present invention, the damper accommodating portion 13 is opened in both directions opposite to each other, Can be adopted. Therefore, it is possible to provide a sufficient damping force exceeding that of a conventional hydraulic damper.

In this way, since the pneumatic damper can be adopted, there is no fear of leakage, so that the periphery of the buffer device is kept clean, and the structure is simple, thereby maximizing the life without worrying about trouble and reducing the cost.

Further, since the case 10 is opened in both the opposite directions in the damper housing portion 13, there is no problem in the undercut when the case 10 is taken out from the mold even if the case is formed as a single body without being divided.

Accordingly, the structure of the mold is simple and the cost is reduced, the life of the mold is prolonged, thereby improving the productivity and reducing the manufacturing cost of the damper.

Meanwhile, as described above, the support protrusions 133 are formed on the upper support surface 131 and the lower support surface 132, respectively, so that it is difficult to assemble the dampers.

The thickness 131t of the upper supporting surface in the damper housing portion 13 is thinned to further improve the ductility of the resin material.

The assembly of the damper 30 with respect to the case 10 is carried out by pulling up the upper support surface 131 which is relatively thin in thickness from the case made of a resin and is lifted up by ductility so as to prevent the interference of the support protrusions 133 The damper is simply inserted.

It will be appreciated by those skilled in the art that the portions referred to as 'upper support surface' and 'lower support surface' can be changed to 'left support surface' or 'right support surface' depending on how the case 10 is disposed .

3, 10 to 15, the hook 50 includes a stator 51 fixed to the rod 33 of the damper, a stator 51 fixed to the stator 51, And a mover 53 which is elastically supported by the resilient member 55. The mover 53 is provided with a locking step 531 at one side for preventing the mover 53 from separating from the stator 51, The stator 51 may be provided with a stop jaw 511 corresponding to the engagement jaw 531.

The elastic member 55 may be a compression spring and the mover 53 may be provided with a spring support rod 532 to which a compression spring is inserted. A through hole 513 through which the end 514 and the spring support rod 532 slide can be formed (see FIG. 10).

The stator 51 is divided into two members 51a and 51b for assembling the mover 53 and the two members 51a and 51b are formed with corresponding concave and convex portions 512a, (512b) may be formed.

In the present invention having the hook having such a configuration, since the hook 50 is divided into the stator 51 and the mover 53, insertion of the latch fixed to the slider, such as the door or the drawer, It is possible to insert it even if it is positioned at

12, when the hook 50 is positioned in the straight section of the guide groove 11 and the latch is not inserted, as shown in FIG. 12, The compression spring as the elastic member 55 is pressed and the mover 53 is pushed so that the latch 2 can be inserted into the hook while the latch 2 The elastic member 55 returns the mover 53 to its original state and restrains the movement of the claw 2 together with the stator 51 b, c).

The hook 50 is guided to the guide groove 11 at the tip end of the case 10 after the hook 2 is inserted into the hook 50 in the case where the slider is opened, (See d and e in FIG. 12) so that the latch 2 can be released from the shock absorber and the latch 2 is released from the shock absorber so that the slider can freely be opened completely The latch 2 is pushed and returned to the movable state by pushing the hook 50 in the rotating state and the latch is fitted in the hook 50 so that the movement of the latch and the slider is transmitted to the damper 30 And the slider is restored to the slow speed by the restoring force of the tension spring 70 to prevent the slider from colliding with the door frame or the drawer main body is the same as the operation state in the prior art.

As described above, the hook 50 is divided into the stator 51 and the mover 53, and the mover 51 is configured so as to be able to move inward by the external pressure, Since it is possible to insert the shock absorber, there is no need to assemble the shock absorber in the state where the shock absorber is inserted into the hook when installing the shock absorber, so that the installation work is remarkably simple and drastically reduces air and time.

Also, when the hook 50 is positioned in the guide groove straight section during use, and the latch 2 is located outside the hook, the inconvenience that the hook of the latch can be inserted and the slider is not closed is prevented.

13 to 15, the mover 53 is formed with at least one guide protrusion 538, and the stator 51 has the guide protrusion 538 A slide groove 518 to be inserted and slid can be formed.

The guide protrusions 538 and the slide grooves 518 may be formed on both sides facing each other (see FIG. 15).

As described above, since the guide protrusion 538 is formed in the mover 53 and the slide groove 518 is formed in the stator 51, the protruding and retreating operation of the mover 53 is accurately performed to improve the quality characteristics.

3, reference numeral 516 denotes a damper rod coupling groove of the hook, and 517 denotes a tension spring fitting portion.

As described above, according to the slider shock absorber having the damper housing part extended according to the present invention, the damper housing part of the case supports the damper only in the upper and lower directions to expand the damper accommodating space to allow the pneumatic damper to be adopted. There is no fear that the damper can be kept clean, the damper is not broken, the lifetime is maximized, the cost is reduced, the structure of the case molding die is simplified, the malfunction of the die is reduced,

Further, since the hook is divided into a stator and a mover and the mover is configured to be able to be immersed by external pressure, even if the hook is located at any position of the case, the latch can be inserted into the hook, It is an excellent technology.
