DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a drawer rail attached to the left and right side walls of a drawer provided with a front panel along the depth direction of a cabinet body, and opposed to the drawer rails on inner left and right walls of the body. And a plurality of load transport rollers interposed between the drawer rail and the support rail on each side to allow the drawer to move, and a depth direction in the drawer rail. A housing extending along the housing, a spring provided in the housing, a slide mounted in the housing so as to be slidable along a depth direction thereof and to receive the action of the spring, and a pivot attached to the slide. A drawer closing device comprising: a mounted pivot portion; and a closing means comprising a projection provided on the side wall of the main body for capturing the pivot portion. That.

[0002]

2. Description of the Related Art Recent drawers are provided with an extension guide fitting, which is provided with a main body support rail and a drawer side draw rail on both sides of the drawer so as to make the sliding movement of the drawer as easy as possible. I do. Rollers, balls or similar slides can be provided to carry the load between the drawer side draw rail and the body side support rail, depending on which conditions are drawn for running and load smoothness. Is given to

[0003] In many cases it has been shown that closed drawers are not completely moved into the resulting rear end position in the body and protrude from the body of the furniture by their front panels. As a result, a situation occurs in which someone strikes the drawer, sequentially injuring a person and damaging the drawer.

[0004] The protrusion of the front panel of the drawer from the front of the furniture creates a situation where the drawer is inadvertently pulled out and is not completely stored in the body of the furniture. However, even if the drawer is pushed with too much energy into the body of the furniture, the drawer may jump back forward again due to the excessive energy.

A drawer locking device is disclosed in British Patent No. 1,
No. 117,071 and in this device 2
A pivot member is provided that can be moved between the two end positions. The pivot member is loaded by a helical spring and is pushed to its respective end position by the spring after it has passed the dead center. The pivot member is attached to a side wall of the furniture. The drawer has on its side wall a projection which is moved into the slot of the pivoting member in the end area of the running path of the drawer. Finally, the projection pushes the pivot member past the dead center position, where the pivot member itself pulls the drawer backwards through the projection.

[0006]

As described above, conventionally, there has been a problem that a closed drawer is not completely moved to a storage position at a rear end and slightly protrudes from a front panel of a furniture body.

It is an object of the present invention to provide a closure device in which the drawer is pulled over a longer distance in the body. In doing so, the drawer can be pulled as evenly as possible. It is another object of the present invention to provide such a closure device which can be mounted on a drawer to save space.

[0008]

According to the invention, it is provided that the spring urges the slide against the housing towards the front panel, whereby the drawer can be pulled out of the cabinet body. This is achieved by a drawer closing device characterized by being drawn out by linear sliding.

[0009] In an advantageous manner, it is provided that the pivoting part, the slide and the spring are mounted on the housing. Such a housing can be easily and quickly attached to the drawer rail.

The housing is attached to the front end of the drawer rail in a convenient manner. In this way, the pivot member can be easily adjusted if there is a disadvantageous pivot. If the drawer rail has a U appearance, the housing is mounted inside the rail.

Hereinafter, two embodiments of the present invention will be described with reference to the accompanying drawings.

[0012]

FIG. 9 shows the essential parts of the drawer and drawer cabinet, namely the cabinet body side wall 1, the body bottom 6, the drawer bottom 2, the two drawer side walls 3 and the drawer rail 5 arranged in the lower area of the drawer frame. The support rail 4 attached to the rear wall 7 and the main body side wall 1 is shown. A plurality of additional transport rollers 29 are interposed between the drawer rail 5 and the support rail 4 on each side, and the drawer can be moved with a slight force.

The drawer rail 5 is attached to the drawer side wall 3 in a conventional manner.

A closing device is arranged at the front end of each drawer rail 5. An important part of the closing device is the housing 9,1
9, pivot levers 11 and 21, slides 10 and 20, springs 13 and 25, and guide rods 12 and 24. These parts are attached to a drawer or drawer lever 5. In this embodiment, the springs 13, 25 are helical compression springs.

The bolts 14 or 22 are arranged on the support rail 4.

In the embodiments according to FIGS. 3, 4 and 7, the pivoting part 11 can be rotated about a vertical axis 15. The pivoting lever 11 has a projection 27 which locks into a recess 29 drilled behind the slide guide groove 18 when the closing device is placed under stress. This position is shown in FIG. In doing so, the drawer is opened. If the drawer is moved to the right, the pivoting lever 11 remains in that position until it hits a projection 14 attached to the support rail 4. In this way, the pivoting lever 11 is turned counterclockwise and the projection 2
7 is moved from its locked position in the recess 28. At this stage, the compression spring 13 can move the slide 10 together with the pivot lever 11 to the left with respect to the housing 9. However, it involves a relative movement, i.e. the pivoting part 11 is supported by the slide 10 at the projection 14 and the spring 13
Press the entire drawer to the right into the furniture body until it collides against the surface of the drawer.

If the drawer is opened, ie moved to the left from the position shown in FIG.
And the position of the pivoting lever 11 does not change until the recess 28 is flush with the projection 27. By doing so, the spring 13 is tightened. If the recess 18 reaches the projection 27, the pivoting part is rotated clockwise and the projection 14 is released.

At this stage, the drawer can be pulled freely without having to overcome the force of the spring.

The embodiments according to FIGS. 5, 6 and 8 operate according to the same principle, only the pivoting part 21 being pivoted about a horizontal axis 26. The pivoting part 21 rests on a slide 20 which can again be moved in a straight line, ie in a straight line in the housing 19, and which is loaded by a compression spring 25. When the drawer is closed (FIG. 6), the compression spring 25 is relaxed and the pivoting part 21 encloses a projection 22 which is attached to the main rail 4.

If the drawer is opened, the pivot 2
1 and slide 20 remain on projection 22 while compression spring 25 is tightened.

However, if the recess 28 is above the projection 27 above the pivoting part 21, the pivoting part 21 is rotated counterclockwise under the action of the compression spring, so that the projection 27 projects into a recess 28 arranged above the projection and collides with the bolt edge 23.

The projection 22 is thus released and the drawer can be withdrawn without obstruction.

When the drawer is closed, the same operations take place as in the embodiment described above. That is, the pivoting portion 21 remains in the position shown in FIG. 5 until it reaches the projection 22 in the furniture body. If the drawer is pushed further into the furniture body, the pivoting part 21 is rotated and the projection slides out of the recess 28 through the bolt edge 23. At this stage, the compression spring 25 is
Then, the drawer rail 5 and the whole drawer are pushed into the body of the furniture.

The housing 9 or 19 can be provided with both projections and has a recess which fits into the pull-out rail 5 in the punching or in which the tongues which have also been punched out of the pull-out rail 5 are locked again. Can be.

Of course, the compression spring 25 is connected to the housing 9,
Instead of at 19, it can be reinforced with a stamped tongue of the drawer rail 5. Similarly, guide rods 12,2
4 can be guided into such a tongue (FIGS. 5, 6).
reference).

[0026]

As described above, according to the present invention, the pivot portion is attached to the slide, and the slide is loaded by the spring and can be slid linearly in the pulling-out direction of the drawer. Thus, it is possible to provide a drawer closing device in which the drawer can be pulled over a longer distance.
