The damper assembly is coupled to the hinge frame and fixed.

And the upper surface of the hinge frame is mounted to have a predetermined inclination, the bottom surface of the housing is preferably formed to have an inclination in the opposite direction to the inclination of the upper surface of the hinge frame.

And it is preferable that the adjusting bolt is screwed to the rear end of the guide hole, so that the position of the damper can be adjusted by the rotation of the adjusting screw.

Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the drawings.

As shown in Figure 1 attached to the damping hinge for furniture according to an embodiment of the present invention (hereinafter referred to simply as a hinge) is a hinge (100, 200, 300) for elastically opening and closing the door (D) and the hinge support The damper assembly 40 which attenuates the closing shock of a door when the door D is closed is comprised.

The hinge includes a door fixing part 100 fixed to the door D, a main body fixing part 200 fixed to a main body (inner side) of the furniture, and the door fixing part 100 and a main body fixing part ( Link portion 300 for rotatably connecting the 200 is included.

The door fixing part 100 is fixed to the opening and closing door (D) of the furniture, it is fixed to the inner surface of the door (D). In general, the door fixing part 100, the flange portion 112 in the state in which the cup portion 110 is inserted into a groove (not shown) formed on the inner surface of the door, the inner surface of the door by a plurality of fastening screws. It is fixed to the door by being fixed to it.

And the main body fixing part 200 is a part which is fixed to the inner wall surface of the main body of the furniture (hereinafter referred to as the "main body"). In general, the main body fixing part 200 includes a mounting plate 210 fixed to the inner side of the furniture body, and a hinge frame 220 fastened on the mounting plate 210. The mounting plate 210 is fixed to the inner surface of the body (M) by using a screw as a plate-like member. And the hinge frame 220 is fastened to the mounting plate 210, it is generally configured to be adjustable between the gap.

The hinge frame 220 has an upper surface 222 and both side surfaces 224 extending downward from both sides of the upper surface 222, and is made from a plate having a predetermined thickness. The inside of the upper surface 222 and the two side surfaces 224 is generally empty, the hinge frame 220 is mounted to the mounting plate 210 by the fastening screw in the state in which the mounting plate 210 is inserted between the two side surfaces 224. Is fixed to the joint. In this case, the hinge frame 220 with respect to the mounting plate 210, it is possible to adjust the height of the predetermined interval and position to both sides.

The link unit 300 connects the door fixing part 100 and the main body fixing part 200 to each other. The link unit 300 is rotatably connected to a plurality of links according to the opening and closing angle of the door. By the internal structure of the link unit 300, the door fixing portion 100 is able to rotate with respect to the main body fixing portion 200, and has an elastic force in a predetermined direction. That is, due to the configuration of the above-described hinge, when the door (D) is closed by a certain angle, it is subjected to elastic force in the completely closing direction is to close the door to the body (M) completely. This elastic force is generated by the internal configuration of the link portion 300 substantially. The hinge described so far is a configuration of a general hinge, the impact of the moment when the door is completely closed by the elastic force described above.

According to the present invention, as shown in Figure 1, the damper assembly 400 is provided on the upper surface of the hinge frame 200. The damper assembly 400, as shown by the arrow, impact that may occur at the moment of closing by contact with the door fixing portion 100 of the door or hinge before the door D is rotated in the closing direction and completely closed. It absorbs the predetermined attenuation action.

The damper assembly 400 of the present invention is mounted on the upper surface 222 of the hinge frame 220. Mounting the damper assembly 400 on the upper surface 222 of the hinge frame 220 is for the following performance. 5 schematically shows the hinge H for convenience of illustration. As shown in FIG. 5, the door D is rotatably supported by the main body M by the hinge H. As shown in FIG. Here, the center of rotation of the door (D) can of course be said to be inside the hinge (H). Therefore, the outer side of the door (the direction away from the hinge) based on the hinge (H) can be said to be a point far from the center of rotation.

That is, in FIG. 5, the point B is more than the point A, and the point C is more distant from the center of rotation than the point B. When the damper assembly 400 is in contact with the closing door and exhibits a damping function, when the damper assembly 400 comes into contact with the damper assembly 400, the damper assembly 400 may have a greater impact than when the damper assembly 400 starts to contact with the damper assembly 400. In other words, when the damper assembly 400 exhibits a damping function, at the point A, since the section is very short, more load is applied. Therefore, the damper assembly 400 in contact with the door (D) at the point C rather than the point B will be able to exhibit a softer and more stable attenuation ability.

In the present invention, the damper assembly 400 is installed on the upper surface 222 of the hinge frame 220 for this reason. That is, by installing the damper assembly 400 in the position as far as possible from the hinge (H), it is in contact with the inner surface of the door at the position that is the most spaced apart from the hinge (H) to provide a more smooth and smooth damping function I'm doing it.

First, the configuration of the damper assembly 400 will be described with reference to FIG. 6. In the illustrated embodiment, the damper assembly 400 includes a housing 410 and a damper 420. The housing 410 is preferably injection molded and has a guide hole 412 into which the damper 420 can enter. The housing 410 has a structure that can be mounted on the upper surface 222 of the hinge frame 220. In the illustrated embodiment, the bottom of the housing 410 is provided with a plurality of elastic hooks 432 and 434 extending rearward. The elastic hooks 432 and 434 are formed integrally with the housing 410 by a synthetic resin material, and are preferably configured in a pair arranged in a straight line.

The damper 420 is accommodated in the guide hole 412 of the housing 410. The damper 420 includes a normal, preferably cylindrical cylinder 422, and a shaft 424 provided to extend coaxially outward from the inside of the cylindrical cylinder 422. The damper 420 itself is already known, so detailed description thereof will be omitted and outlined. A fluid having a viscosity is embedded in the cylinder 422, and a piston or plunger (not shown) connected to the shaft 424 is installed. And the piston or plunger is provided to be movable in the axial direction in the interior of the cylinder, it is configured so that the above-described fluid flows along the inside or outside of the piston or plunger by a predetermined amount. Therefore, when an external force is applied to either side of the cylinder 422 or the shaft 424, a damping function is provided by the relative movement of the fluid and the piston. In addition, a spring is also built into the cylinder 422, and the damper, which has a damping function while being compressed, returns to its original position (a state in which the cylinder and the shaft are maximized in length) by the force of the spring.

According to the present invention, the cylinder 422 protrudes a predetermined distance toward the front of the guide hole 412 of the housing 410, and in such a state that the door (D) is closed in contact with the cylinder 422 and a predetermined damping The process goes on.

The other end of the guide hole 412 of the housing 410 is screwed to the adjustment bolt 414 is threaded on the outer periphery. Of course, the thread processing corresponding to the inner periphery of the other end of the guide hole 412 of the housing 410 is provided. By adjusting the position by rotating the adjusting bolt 414, it is possible to substantially adjust the degree of protrusion of the cylinder 422 of the damper 420, which is the point at which to start the contact with the closed door Means that can be determined.

And the inside of the guide hole 412, the coil spring 416 may be further installed in the assembled portion of the shaft 424. The spring 416 may absorb the impact of the door more safely and may also perform a function of restoring the damper 420 to its original position.

The pair of elastic hooks 432 and 434 formed on the bottom surface of the housing 410 is coupled to the pair of engaging holes 232 and 234 formed on the upper surface 222 of the hinge frame 220, as shown in FIG. . As the elastic hooks 432 and 434 extend rearward, a spacing t (see FIG. 6) formed between the bottom surface of the housing 410 is substantially fitted to correspond to the thickness of the hinge frame 220. It must be decided.

The elastic hooks 432 and 434 extend backward and have a predetermined distance t because the force is always applied to the rear when the door contacts the damper 420 while the door is closed.

Naturally, the locking holes 232 and 234 may also be formed in a straight line, that is, in a pair arranged in the longitudinal direction on the upper surface 222 of the hinge frame 220. The width of the locking holes 232 and 234 and the width of the elastic hooks 432 and 434 may also be appropriately adjusted so that the elastic hooks 432 and 434 are not easily separated when they are coupled to the locking holes 232 and 234. In order to more easily fit the elastic hooks 432 and 434 into the engaging holes 232 and 234, the spacing t of the elastic hooks 432 and 434 is relatively large at the inlet side so that the elastic hooks 432 and 434 can be inserted smoothly and the interval t The rear part of the) is preferably determined to be firmly fitted to the thickness of the hinge frame 220 to be fastened with sufficient friction. In the illustrated embodiment, the locking hole 232 is formed in a shape having a two-stage width having a relatively wide width of the front portion (left side) and a relatively narrow width of the rear portion (right side). .

As shown in FIG. 3, which is a plan view of the closed door, the upper surface 222 of the hinge frame 220 may have a predetermined inclined surface, and all hinges currently developed and commercialized are the same. . In addition, the cylinder 422 of the damper assembly 400 preferably contacts the door D at a right angle if possible. It is not preferable to move away from the right angle because the component force of the external force applied by the door D acts in a direction away from the hinge frame 220. In practice, however, the door is in a closed state and is substantially perpendicular to the wall when viewed from the top view, so that the damper 420 and the door D are in contact with each other at a substantially right angle. However, if possible, the cylinder 422 of the damper 420 and the door D are preferably in contact with each other at a right angle. Therefore, as shown in FIG. 3, the bottom surface of the housing 410 is formed as an inclined surface corresponding to the top surface of the hinge frame 220, so that the top surface 430 of the housing 400 is substantially the door D. It is preferable to install so as to be close to the right angle.

Next, the overall operation using the damping mechanism of the present invention will be described with reference to FIGS. 1 and 3.

1 shows a state in which the door begins to close in a perspective view, and FIG. 3 shows a state in which the door is completely closed in plan view. As illustrated, when the door D is closed to some extent, the cylinder 422 of the damper assembly 400 comes into contact with the door D side. In the present invention, as described above, the cylinder 422 is preferably in contact with the outer side of the door (direction away from the hinge) so that the damper assembly 400 can perform the damping operation most smoothly and smoothly.

Therefore, it is preferable that the cylinder 422 of the damper assembly 400 is in contact with the K portion of the door D, which is more outer than the door fixing part 100 of the hinge. When the cylinder 422 contacts a part of the door fixing part 100 of the hinge H while the door is closed, that is, the cylinder 422 is a part 100K of the door fixing part 100 in FIG. 1. There may be a case of contact with. However, the cylinder 422 is in contact with a part of the door fixing part 100, the door fixing part 100 is assembled in a state protruding than the inner surface of the door, so that it is close to the front end of the cylinder 422 Since the door fixing part 100 has a substantially close distance from the rotating shaft, the door fixing part 100 is not enough to exhibit a smooth and smooth damping performance.

Accordingly, the tip of the cylinder 422 of the damper assembly 400 may be said to be in direct contact with the inner surface of the door D, rather than in contact with a part of the door fixing part 100 of the hinge. For example, it is preferable to contact the part K of the door of FIG. As described above, when the direct contact with the portion K of the door D, the contact between the cylinder 422 and the door is a relatively far point from the center of rotation of the door, as described above, a more smooth damping operation is possible. And at the same time there is an advantage that the door (D) and the cylinder 422 can be in contact with the right angle as possible.

Therefore, as shown in FIG. 3, when the door D is completely closed with respect to the main body M, the cylinder 422 completely enters the guide hole 412 of the housing 400, and thus, the damper 420. It closes while the damping function is exerted. This substantially means that when the door D is completely closed, the impact of the impact with the main body M can be suppressed, so that the parts can be used for a long time and the noise can be sufficiently suppressed. .

In the illustrated embodiment, the housing 410 is configured to not protrude outward from the upper surface of the hinge frame 220, that is, the width of the housing 410 is less than or equal to the width of the hinge frame 220. It cannot be limited to this. For example, the housing 410 may be molded to have a larger width than the hinge frame 220. In another embodiment, the housing 410 may be molded in a shape in which the width of the housing 410 extends outward from one side of the hinge frame 220.

As described above, according to the present invention, the damper assembly 400 is fixed to the upper surface of the hinge frame 200 so that the cylinder 422 and the door start contacting at a point relatively far from the center of rotation of the door. It can be seen that. And it can be seen that by using a pair of elastic hooks and engaging holes extending to the rear, by fixing the damper assembly to the upper surface 222 of the hinge frame 220, it is possible to maintain a firm coupling state.

As described above, various modifications are possible to those skilled in the art without departing from the basic technical scope of the present invention, and the protection scope of the present invention is defined in the appended claims. It is obvious that it should be interpreted on the basis of.

As described above, the hinge according to the present invention can expect the following effects.

First, according to the present invention, by integrating the damper assembly into the hinge, it can be seen that the shock generated when the door is closed can be absorbed. Therefore, it is expected that the furniture can be protected from impact while suppressing the occurrence of noise due to the closing operation of the door as much as possible. In addition, the smooth closing operation of the door is actually due to the multi-functionality of the furniture can be a matter of course to further improve the ease of use.

In addition, according to the present invention, since the damper assembly is mounted on the upper surface of the hinge frame, the assembly process may be substantially convenient and the effect of improving productivity due to the improvement of workability may be expected.

In addition, by mounting the damper assembly on the upper surface of the hinge frame, the portion where the cylinder of the damper comes into contact with the door becomes a point relatively far from the rotation axis of the door. Therefore, it can be said that the advantage of enabling smooth and smooth operation during damping operation is expected.
