The present invention relates to a rail for a drawer, and more particularly to a damping device for a drawer rail and a furniture equipped with the device to prevent the impact caused when the drawer collides with the furniture when the drawer installed in the furniture is closed.

The furniture is provided with drawers for storing various items. Generally, a guide bar is formed on the furniture, and a drawer is placed on the furniture so that the furniture can be opened and closed.

The drawer is formed with a handle so that when the drawer is pulled, the drawer slides along the guide bar, protrudes forward and opens, and the pushed surface is closed in its original position.

At this time, the noise is often generated when the drawer is opened and closed by the friction force between the drawer and the guide bar. If the drawer has a lot of contents, the drawer does not open well because the friction force increases due to its own weight.

In order to solve the above problems, a rail such as a train rail is installed on the guide bar, and a sliding bar sliding along the rail is installed thereon, and a rolling bearing is installed between the rail and the sliding bar so that the sliding bar can slide smoothly on the rail. do.

When the drawer is installed on the sliding bar, the drawer can be opened and closed very smoothly when the drawer is opened and closed, and since rolling bearings are installed, the sliding bar does not generate noise even if the weight of the drawer is heavy, and thus the slide bar is smooth. Many provided rails are employed.

The drawers with the above-mentioned rails open and close smoothly when they are opened and closed, so they are convenient to use.However, when the drawer is pushed in without pulling the handle until the drawer is completely closed, the drawer is thumped and closed due to the acceleration force. Injuries can also occur if your fingers are caught between furniture.

Therefore, by attaching a shock-absorbing member such as rubber to the front end of the drawer to reduce the noise, such a configuration does not fundamentally solve the physical injury caused by noise or finger pinch, etc. generated when the drawer is closed.

The present invention is to solve the problems as described above, the furniture drawer does not accelerate even if you close the drawer when you close the drawer when you close the drawer is not accelerated and damped so that it closes gently without damping, fingers, etc. To provide a damping device for the drawer rail and furniture to which the device is mounted so as not to be pinched.

The present invention is a damping groove and a damping rail is formed in the longitudinal direction in order to achieve the above object, the front end of the damping rail is bent downward housing and the engaging groove is formed; A moving trolley installed on the damping rail and reciprocating; A hollow cylinder connected to one end of the housing; A cylinder rod inserted into the cylinder to be in close contact with the front end of the cylinder to have a constant frictional force, and a rear end of the cylinder rod being connected to the moving table; It provides a damping device for a drawer rail, characterized in that one end is fixed to the outer side of the cylinder and the other end is fixed to the moving cart.

In addition, the bracket is attached to one side of the furniture drawer and the upper rail is formed; One side is installed on the rail of the bracket and slides back and forth, and the other side is a sliding bar fixed to the furniture drawer; A housing installed at one side of the rail and having a damping groove and a damping rail formed in a longitudinal direction thereof, and a front end of the damping rail bent downward to form a locking groove; A moving trolley installed at the damping rail to reciprocate; A hanging bar formed downward in the sliding bar and protruding to engage with the moving cart; A hollow cylinder connected to one end of the housing; A cylinder rod inserted into the cylinder so that the front end is in close contact with the inner diameter of the cylinder and the rear end is connected to the moving cart; The front end is fixed to one side of the cylinder and the rear end is fixed to the reciprocating moving trolley; provides a furniture equipped with a damping device for a drawer rail comprising a.

On the rail 20, a sliding bar 30 reciprocating along the rail is installed, and the sliding bar 30 is coupled with the drawer to interlock when the drawer is opened and closed. That is, when the drawer is pulled, the drawer is pulled along the sliding bar 30 and pushed to close along the sliding bar 30.

One side surface of the sliding bar 30 is formed with a catch 40 to be engaged with the moving trolley to be described later, the catch is composed of the first, second, third locking projections 42, 44, 46 protruding downward.

A side of the rail 20 has a damping groove 52 of a predetermined length in the longitudinal direction, the housing 50 having a pair of damping rails 54 formed on both sides of the damping groove 52 is coupled, the damping rail A locking groove 56 bent downward is formed at the tip of 54.

The damping groove 52 is provided with a moving cart 60 to reciprocate. The moving cart 60 is formed with a pair of first and second locking parts 62 and 64 opposed to each other at a predetermined interval, and a lower part of the damping groove 52. A spring fixing portion 66 protruding downward is formed, and support bars 68 are formed on both sides of the front side to cover the damping rails 54.

A hollow cylinder 70 is coupled to the front end of the housing 50, and the partition wall 80 is formed therebetween, and the partition wall 80 is formed with a communication port 82 communicating with each other.

The cylinder 70 has a head portion 92 whose tip is in close contact with the inner diameter of the cylinder 70 and a rod portion 94 extending from the head portion and connected to the moving cart 60 through the communication port 82. The cylinder rod 90 is formed, and the head part 92 is coated with the cushioning material (not shown) which gives a friction force with the cylinder 70. In addition, the outer periphery of the head 92 is formed with one or several oil holes 96 in communication with the outside in the longitudinal direction, it is possible to release the vacuum pressure generated when the cylinder rod 90 back and forth.

The lower end of the cylinder rod is formed with a spring mounting portion 110 is opened, the spring mounting portion is provided with a spring 120, one end of the spring 120 is fixed to the front end of the spring mounting portion 110 of the spring 120 The other end is connected to and fixed to the spring fixing portion 66 of the mobile truck 60.

Referring to the operation of the drawer rail according to the present invention configured as described above are as follows.

As shown in FIG. 3, the bracket 10 is fixed to the furniture around the drawer, and the sliding drawer fixed to the drawer is pulled when the drawer closed while the sliding bar 30 fixed to the drawer is installed on the rail 20 of the bracket. Bar 30 is pulled simultaneously.

When the sliding bar 30 is pulled, the moving rod 60 engaged with the catch 40 and the first and second locking protrusions 42 and 44 is pulled, and the cylinder rod 90 connected to the moving cart 60 is pulled and the spring is pulled. 120 is tensioned. The moving trolley 60 proceeds along the damping rail 54, and the support trolley 60 formed on both sides of the moving trolley 60 is located in the locking groove 56 formed at the tip of the damping rail 54. The front part of the falling into the locking groove 56 is fixed. Therefore, the spring 120 maintains a tensioned state.

When the front portion of the moving trolley 60 falls into the locking groove 56, as shown in FIG. 4, the second locking protrusion 44 is released from the moving trolley 60 while the sliding bar 30 continues. That is, the sliding bar 30 proceeds freely in the released state in the moving cart 60 until the drawer is completely opened.

On the contrary, when the drawer is closed, the open drawer is pushed along the sliding bar 30 while the drawer is caught by the first catching part 62 while being pushed by the inertia force of the drawer and the front portion of the moving cart 60 is locked. 56)
