Description

Folding leg mechanism for furniture.

Field of the Invention

The invention relates to a leg mechanism folding to be used in any type of furniture, mainly on tables, which allows transport and assembly simple.

Background of the invention

Currently there are countless designs and mechanisms aimed at acting as legs or supports of all kinds of furniture, however, there are few modalities that allow the legs are folded for easy transport and handling of A simple and effortless way.

Moreover, the mechanisms that are known to ensure the blocking of the legs once deployed, they are, to date, complicated or difficult to handle by the user, since they require the use of additional tools.

Description of the invention

The present invention offers a novel folding leg mechanism for furniture, easily foldable and Folding with a simple locking mechanism. The design of this mechanism responds to the need to use a leg mechanism folding with 90º turn. This can be operated manually without great effort and without the use of tools of any kind.

The mechanism of the invention comprises a leg with a built-in lock and unlock insert, which is operated with a lever, which in one of its positions leaves free the leg for possible rotation and in the other position, the leg is locked in the maximum turning position. Also the mechanism It includes a safety stop that also prevents the rotation of the leg once deployed, so that in order to fold the leg once the locking lever is in position corresponding unlocking, the leg must be displaced longitudinally so that it is released from the action of the stop and You can be turned 90º for its dejection.

Likewise, the mechanism is integrated into the board thickness.

Description of a preferred embodiment of the invention

The mechanism consists of two parts, visibly differentiated and shown in the figures 1-7:

- One leg (1), and

- An integrated insert (3) nailed to the furniture, where the locking mechanism is housed.

The leg (1) is made of aluminum and section rectangular with an insert (5) in the housing closest to the interlocking with two conical housings (9) and with a support (2) adjustable to the ground, at its other end, as seen in the figures 7.

The insert (3) comprises a locking mechanism which consists, as can be seen in figure 7, in one piece of aluminum in which the different pieces that allow the movement of locking shafts (6) that will be inserted in the conical housings (9) of the insert (5) of the leg (1). Each axis of Lock (6) consists of two pieces joined together by threaded so that it can be adjusted by turning the end piece the length of each axis and therefore its blocking pressure on the conical housings Both the insert (3) and the mechanism that houses, are integrated within the thickness of the board.

The insert (3) has a projection with a hole oval (10) inside which the axis of rotation (4) is housed by which the insert (3) is attached to the leg (1) so that it allows lower the leg (1) thanks to its turn. On the other hand, the insert (3) It contains a stop (11) that blocks the rotation of the leg (1) to avoid its dejection, as a safety mechanism, as shown in figures 1-6.

Inside the insert (3) two axes slide (6), with movement of exit and entrance that cross the holes (12) of the insert (3) for guiding the locking shafts (6). These axes are held and pushed by means of a transmitter. of movement (7). The movement transmitter (7) is pushed by a manual actuation lever (8), which is attached to the insert (3) and to the transmitter (7) by means of two axes. The position angle of the transmitter (7) with the operating lever (8) and with the insert (3) it causes the mechanism to be completely locked while the lever (8) is not operated manually.

The operation of the mechanism requires a manual intervention, as shown in the figures 1-5. The leg (1) in original position is totally down on the insert (3). The leg is turned (1) until place it at 90º with respect to the insert (3), sliding it in such so that it fits with the stop (11) of the insert (3). Once in this position the lever is operated (figures 6, 5 and 4), which causes the two locking shafts (6) are inserted in the housings (9) of the leg and prevent the rotation of the leg. When the lever (8) is in the locked position, figure 4, the mechanism does not leave the accidental unlocking it without manual intervention. This This is because the situation of the shafts (6), the lever (8) and the transmitter (7) makes it impossible to reverse the mechanism.

To lower the leg again, the lever (8) to its rear position, which pulls the axles (6) of lock, subsequently, to unlock the leg rotation (1) it Raise is above the stop (11), freeing this from the action lock the stop, and the leg is turned 90º for folding.
