Description

{Damper for furniture gas cylinder}

The present invention relates to a gas cylinder damper for a furniture, and more particularly, to a gas cylinder damper for a furniture which can be easily installed in a flap changer of a kitchen.

Generally, a damper for a furniture is installed in a door that is opened and closed by a hinged type, so that it absorbs impact applied when the door is closed and smoothly closes, thereby preventing noise and preventing damage to the door.

Recently, a lot of flap shelf-type cabinets are installed in the kitchen in terms of design. The flap is a cabinet that pushes up the door to the upper side unlike the existing cabinet which opens the doors to the right and left. The flap is provided with a cylinder for opening and closing the door, and a damper is provided to prevent noise and impact generated when the door is opened and closed separately. That is, since a damper must be provided separately from the cylinder, it is inconvenient to carry out a double operation.

Further, since the damper directly contacts the door, there is a problem that damage due to the damper occurs in the door that contacts the damper as the number of times of use increases.

Like parts are designated with like reference numerals throughout the specification.

1 to 3, a gas cylinder damper for a furniture according to an embodiment of the present invention will be described.

FIG. 1 is a perspective view showing a gas cylinder damper for a furniture according to an embodiment of the present invention, FIG. 2 is a side view of the gas cylinder damper for furniture shown in FIG. 1, Is a side view of the damper. 1 to 3, a gas cylinder damper for a furniture according to an embodiment of the present invention includes a first fixing part 10, a second fixing part 20, a cylinder part 30, and a buffer guide part 40, .

The first fixing part 10 is connected to the door 100 and the first fixing part 10 is provided with a buffer part 11 for absorbing the impact of the door 100.

The gas cylinder damper for a furniture according to an embodiment of the present invention can be installed in a door that rotates in the left and right direction around the furniture. Alternatively, the gas cylinder damper can be installed in a door that rotates vertically .

The first fixing part 10 includes a plate 12 and a buffer part 11. The buffer part 11 may include a bracket 111 and a moving part 112. [

The bracket 111 is a member connected to the plate 12. The bracket 111 may be formed separately from the plate 12 and coupled to the plate 12 by bolting or welding or otherwise formed integrally with the plate 12.

The moving part 112 is inserted into the bracket 111 and is a member reciprocating linearly along the longitudinal direction of the bracket 111.

The second fixing part 20 is a member connected to the furniture 200. The second fixing portion 20 may be formed of a metal material such as an iron plate or aluminum in a flat plate shape, or may be formed of plastic. The second fixing part 20 can be screwed to the furniture 200 using bolts or the like.

The cylinder part (30) is a member hinged to the second fixing part (20). The length of the cylinder part 30 can be adjusted by opening and closing the door 100. Specifically, the cylinder portion 30 includes a rotation portion 31, a piston 32, and a housing 33.

The rotary part 31 is hinged to the second fixing part 20 and rotates about the second fixing part 20 as a door as the door 100 is opened and closed.

The piston 32 is connected to the rotation part 31 and the housing 33, and a part of the piston 32 is inserted into the housing 33.

The housing 33 is a member whose one end is connected to the buffer guide portion 40 and whose length is fixed.

The distance between the first fixing part 10 and the second fixing part 20 is changed according to the rotation of the door when the door 100 is opened. At this time, the piston 32 is inserted into the housing 33, or protruded to the outside of the housing 33, and the length of the piston 32 protruding outside the housing 33 is adjusted to connect the door and the furniture.

A method of inserting the piston 32 into the housing 33 or protruding outwardly and rotating like the rotation part 31 to control the opening of the door is a known method and thus a detailed description thereof will be omitted.

One end of the cushioning guide portion 40 is connected to the cylinder portion 30 and the other end thereof is hinged to the first fixing portion 10.

The buffer guide portion 40 may be formed of a metal material or may be formed of a plastic material such as the first fixing portion 10 or the second fixing portion 20 without any particular limitation. The cushioning guide part 40 has a protrusion 43 protruding in the longitudinal direction of the moving part 112 at a part of one end connected to the cylinder part 30. Therefore, when the door is closed, the protruding protrusion 43 comes into contact with the moving part 112.

When the door 100 is opened, as shown in FIG. 2, the moving part 112 protrudes from the bracket 111 as much as possible. At this time, the piston 32 is also maintained in a state where it protrudes from the housing 33 as much as possible. The straight distance between the first fixing part 10 connected to the door 100 and the second fixing part 20 connected to the furniture 200 is shortened and the piston 32 is moved toward the inside of the housing 33 So that the rotation of the door is naturally induced. At the same time, the rotation part 31 rotates about the second fixing part 20 so that the door 100 can be contacted with the furniture 200 and closed. The principle that the piston 32 is inserted into the inside of the housing 33 or the rotation part 31 rotates around the second fixing part 20 is similar to the method when the door of a general furniture is closed.

As shown in FIG. 2, before the door is closed, the cushioning guide portion 40 has a protruding portion 43 protruding from the first fixing portion 10 and protruding from the moving portion 112, . When the protrusion 43 of the cushioning guide portion 40 contacts the moving portion 112, the cushioning guide portion 40 applies a force to the moving portion 112, and a portion of the cushioning portion 40 protruding outside the bracket 111 The portion 112 is inserted into the bracket 111. The buffer guide 40 contacts the moving part 112 and a force for moving the moving part 112 acts as a damper for mitigating the impact when the door is closed.

Specifically, when the door is closed, the movement of the door is controlled by the movement of the cylinder part 30, and the door is tightly closed. When the distance between the door and the furniture becomes narrow, the cushioning guide part 40 contacts the moving part 112, 112) to reduce the moving speed of the door, which weakens the closing force of the door to the furniture, thereby weakening the impact on the door and furniture. Further, the door is slowly closed to the furniture, so that the noise generated when the door is closed can be prevented.

The moving part 112 protrudes outward from the bracket 111 due to the spring installed inside the bracket 111 when the door is opened and the force received from the cushioning guide part 40 when the cushioning part contacts the cushioning guide part 40. [ The moving part 112 can move toward the inside and the outside of the bracket 111 because the inside of the bracket 111 is filled with oil or the like. The method of linearly moving the moving part 112 into the bracket 111 after coming into contact with the cushioning guide part 40 is similar to the operation principle of other known general damper.

The gas cylinder damper for furniture according to an embodiment of the present invention includes a cylinder for opening and closing a door and a damper for preventing a shock applied to a door from being integrally formed, and a cylinder and a damper There is an effect that can be. Also, by preventing the damper from directly touching the door, the effect of preventing damage to the door can be expected.

On the other hand, the first fixing part 10 may be provided at one end thereof with a contact part 13 which can be in contact with the buffering guide part 40.

The contact portion 13 may be connected to the first fixing portion 10 by an adhesive, or by various methods such as bolting or welding.

The contact 13 may, but need not, be formed of a material capable of absorbing impact, such as a sponge or rubber.

The protruding portion 43 of the cushioning guide portion 40 is pressed against the contact portion formed in the first fixing portion 10 when the cushioning guide portion 40 contacts the moving portion 112 to reduce the moving speed of the door, (13). At this time, when the contact portion 13 is formed of a material such as sponge or rubber, the noise and impact generated when the buffer guide portion 40 hits the first fixing portion 10 can be reduced. In addition, it is possible to prevent a phenomenon that the buffer guide portion 40 is in contact with the first fixing portion 10 due to frequent closing of the door, thereby wasting a part of the first fixing portion. That is, since the cushioning guide portion 40 is in contact with the contact portion 13 other than the first fixing portion 10 and the contact portion 13 is worn out due to frequent closing, only the contact portion 13 needs to be replaced. 10 can be prevented from being damaged.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, Of the right.
