A device for closing and/or opening a drawer (13) of a piece of furniture. This device comprises a latch (1) and its respective retainer (4), where one is attached to the piece of furniture and the other is attached to the drawer (13). The device is characterized by the fact that the latch (1) is fastened to a plate (2) equipped with means (12) suitable for positioning the plate precisely with respect to the retainer (4), and by the presence of elastic means (8) suitable for exerting a pushing force on the drawer (13) of the piece of furniture in the opening direction.

Description

The circuit breaker lock device of drawer guide system

Technical field

The present invention relates to a kind of device of closing and/or opening of moving-member of furniture.More particularly, relate to and a kind ofly have element and elastic mechanism so that the drawer of opening.

Background technology

Now, the door bolt type device of several types or latch be used to open or close or at least-given function-convenient furniture door or drawer moves when designing according to them.These latches produce slight resistance when closing; This power is stored within the flexible member, and in thereafter inverse operation, discharges when opening.

When utilizing the opening of the convenient drawer of latch, drawer remains on its fastening position under the effect of proper device, this device both can be the element that separates with latch also can with its integrator, such as hook type arrangements, magnet, or the like.

At this moment,, at first must touch drawer, be released in the elastic energy of storage when closing, produce an edge then and open the thrust of direction on drawer to unclamp latch in order to open drawer.An advantage of said apparatus is not need handle or similar grasp device on the drawer, and these devices may be undesirable from aesthetic or other angles.

In the up-to-date drawer of technology, the latch of the above-mentioned type directly is fixed on furniture and is installed on the frame part and drawer of drawer; Unfortunately, their arrangement often causes that owing to size or position inaccuracy drawer blocks or can not close tight fully.If the function of latch can not normally act on sometimes, possibility is because of drawer and handle does not match and/or because drawer is not fully opened, make that opening drawer becomes very difficult.

Summary of the invention

Main purpose of the present invention provides the closing and/or device for opening of drawer guide system of a pin-type that can overcome above-mentioned shortcoming.Moreover, this device also should economically be made with being easy to.

This purpose utilize the described pin-type of claim 1 close and/or device for opening accomplished.

Because its good performance, device of the present invention can be rapid, accurately and easily assembles.The assembling of this device does not need to utilize special instrument and fixation, guarantees can not be damaged or break away from its fixing drawer guideway.Set total joint precision, the rule of latch proper handling is guaranteed.Latch also comprises a flexible member, under its effect the opening procedure of drawer is become easily or fully need not be manual.

Corresponding claims have illustrated most preferred embodiment of the present invention.

The specific embodiment

Below be with reference to above-mentioned accompanying drawing, to the detailed description of the most preferred embodiment of drawer slide (following) with " G " mark.Above-mentioned drawer slide comprises a latch 1 that is fixed on the plate 2, and described plate is fixed on the guide rail 3 of drawer 13.Do not show second guide rail among the figure, it is usually located in the drawer, and constitutes guidance system together with first guide rail.In this embodiment of the present invention, latch 1 is fixed on the fixed guide 3, but also can still be fixed within the scope of the invention on the rail plate 5.

Retainer 4 constitutes an integral body with rail plate 5, and is stretched out by the sidewall of " C " shape with two ribs.Like this, above-mentioned retainer facilitates on the guide rail that is fixed on the left and right sides.

Latch 1 can, such as, utilize a bender element 11, maybe can utilize suitable method to be fixed on the plate 2, with integral body of its formation as welding or the mode fastened.On plate 2, have two short and small, by such as, the tongue piece 12 of die forming.These tongue piece protruding plate faces, and because material and manufacturing process can apply flexible clamping force on the surface of fixed guide 3.The standing part 3 of drawer slide G comprise two cardinal principles elongated or the seam shape, the hole that can hold tongue piece 12.Slip can be pinned the tongue piece 12 in plate 2 corresponding holes, and this mechanism makes plate 2 and fixed guide 3 integrators.

Scope of the present invention also comprises processes the tongue piece in the fixed part 3 of drawer slide G, or to fixing with the slide unit 5 similar plates of drawer slide G.

In switching process, latch with and other guide rails, be rail plate 5 in the present embodiment, the interaction of the retainer of one.Retainer 4 can directly process from the material of guide rail 5, also can use welding or screw on guide rail.Retainer 4 can interact with the latch that is suitable for keeping drawer to cut out, no matter and it is a magnetic, machinery, or alternate manner.

Operation to drawer slide is illustrated below.When closing drawers, rail plate 5 moves along the direction of arrow " C ", and a rib of retainer 4 promotes the handle 6 of latch 1, is located at position shown in Figure 2.On this position, magnet 7 is inhaled retainer 4 on latch 1, because latch is in the position of pinning, keeps drawer to close.In order to open drawer, must act on slight thrust thereon.This thrust makes rib 4 pushing handles 6 of retainer, and it is released in unillustrated retainer from figure.At this moment, the elastic energy of storage reappeared when latch was closed drawer, and this energy is converted into power and promotes rail plate 5 along the direction of opening.Above-mentioned effect only can make drawer partially open, and whole the opening of drawer needs to rely on second elastic mechanism.

Advantageously, elastic mechanism comprises that such as an extension spring 8, the one end is fixed on the retainer 9 of fixed guide 3, and the other end links to each other with the retainer 10 of rail plate 5.Spring 8 combines with the thrust of opening drawer.Particularly, the power that the power that spring 8 provides and latch produce combines, to increase opening stroke or drawer being opened till positive stop fully of drawer.The selection of spring should with the coupling mechanism force of the reversible maintaining body of aforesaid drawer, machinery or magnetic consistent.

Of the present invention open and/or shutoff device also can be used for the different different embodiment of latch size.Such as, handle 16 is longer than the handle among Fig. 1 embodiment 6 in the embodiment shown in Figure 1A.This embodiment since flexible member and latch become one and increased the stroke of handle, so that open the mobile increasing of drawer, thereby need not open and increase an additional spring 8 for ease of drawer.

The described specific embodiment of presents is not construed as limiting the scope of application of this patent, and the scope of this patent is included in all embodiment in claims.
