Description

Fork with height adjustment for hitch of drawer autocierres.

Field of the Invention

This invention concerns a device that is knows with the name of fork and that, mounted in the drawer, at closing this comes a time when it is hooked by a mechanism which is called "autocierre" and which is responsible for promoting the closing of the drawer in a final section of its route without needing that the push from the user is then maintained, with which is to ensure that the drawer will always be perfectly closed and the message is transmitted to the user that to close the Drawer is enough a moderate thrust, which ends up translating closures softer and better drawer and furniture life.

Prior art

In this field it happens that the location of the self-closing mechanism may vary depending on whether it is on the side of the furniture or in the guide on which the drawer slides; in any case, the fork and the self-closing are installed in different elements that move relatively and that is precisely in this displacement when the joint operation has to be produced by which the fork has to be hooked by the self-closing to fulfill its
function.

This mode of operation requires a considerable precision for correct operation during the usual long life of a drawer, for example that of a kitchen furniture that has to withstand a lot of performances; and, in addition to what has been said, the scope of this precision It is also affected by the fact that the drawers themselves usually incorporate height adjustment means for leveling in the furniture.

In this regard, not only are several known fork solutions, but forks are also known equipped with means capable of height adjustment that allow to adapt to each particular installation.

Among the known solutions of forks with height adjustment there are some in which its constitution is complex and expensive, requiring complicated and expensive operations at the time of factory assembly; Other known solutions in this regard are cumbersome to handle and / or its regulation is not precise and / or progressive enough; For example, solutions that could be called encapsulated are known in that the movable part that varies the working height of the fork is like a box encased in its entire contour by the fixed part of the
same.

Explanation of the invention and advantages

Faced with this state of affairs, the invention that concerns us refers to a fork with height adjustment for drawer autocierres hitch, which consists of a body fixed, box-shaped open at its back and top, and a mobile body that has its back flush with the fixed body and that on its sides and front it has vertical sliding adjustment in the sine of the fixed body, whose fixed and mobile bodies are attached each other by a plane in which the fixed body has a horizontal striatum that is in sliding operating relationship by frontal coupling with a horizontal splined reciprocal of the mobile body; the fixed body has a lower hole and a top hole for two tie down screws to the drawer through of the mobile body, as well as a window that is elongated vertically and that on one of its sides it has a rack teeth liable to engage with the carving of the phillips tip of a screwdriver; said movable body consists of a bracketed head that at all times emerges with respect to the fixed body and a tail slider coupled to this fixed body, whose mobile body has a conical seat for the phillips tip that, at the end of the Sliding operating stroke in the fixed body, this conical seat it is located in operative relation with the ends of the teeth of zipper, whose movable body has a lower neckline and a upper slide through which the screws pass through; and whose fixed and mobile bodies have conjugate guidance means Slider from the second to the first.

This solution responds to a philosophy constructive box and lid that is very simple to manufacture, which employs a minimum amount of material and that is assembly enormously simple by simple sliding of the mobile body in the fixed body

As for its regulatory capacity, taking into account that striates can become very thin, this system of regulation allows the progression to be by very small jumps and that, therefore, be of great precision.

In the description of the preferred embodiment which is discussed below clearly explains the way perform the simple maneuver to adjust the height with the fork installed in the drawer.

As for the drive for regulation It is also very simple and fast, since it is enough to use a tool as usual and common as is the phillips tip of a screwdriver that is always available in the provision of own tool of a furniture installer.
