Description

OBJECT OF THE INVENTION

Turntable locking device.

FIELD OF THE INVENTION

This device is intended to be used preferably for the articulated assembly of constituent plates of seats in children's chairs and folding highchairs.

BACKGROUND OF THE INVENTION

There are different devices for locking child seats and folding highchairs. For example, the one constituted by a strap that relates the seat to the frame that constitutes the rear support, in Utility Model No. 200401524, and that corresponding to PCT WO 2008/028598 which is incorporated in a transverse axis where the seat is articulated , the backrest and the front and rear legs.

SUMMARY OF THE INVENTION

The object of this invention is a rotating plate locking device, which rotates transversely between two stringers and allows the plate to be stabilized in two positions, one of deployment in a practically horizontal arrangement, and one of folding practically aligned in the same plane determined by the stringers. .

For this, the device is arranged on each side of the plate and is characterized by comprising under it a longitudinal plate which on its back forms a support bending against the rear face of the crossbar and which at its front is coupled to a stop integral with the side edge of the plate and which rests against the front face of the crossbar.

The coupling of the plate to the stop comprises anchoring means elastically requested that allow its separation for the unlocking of the device, the stop presenting a push button related to the anchoring means to obtain the unlocking of the device and the free rotation of the plate.

These and other characteristics will be better derived from the detailed description that follows, to facilitate which is accompanied by two sheets of drawings in which a practical case of embodiment has been represented that is cited only by way of non-limiting example of the scope of the present invention

In the drawings:

Figure 1 shows in perspective the device object of the invention in blocking arrangement,

Figure 2 illustrates in an external side elevation the device in an unlocked arrangement,

Figures 3 and 4 represent this device seen in plan in lock and unlock arrangement, respectively, and

Figure 5 shows the device seen in inner side elevation.

DETAILED DESCRIPTION

According to the drawings, this locking device (1) is arranged on each side of the plate (2) which by means of shafts (9) is rotatably coupled between two stringers (4).

This device comprises under the plate (2) a longitudinal plate (3) which in its back forms a support bending (5) against the rear face of the crossbar (4) and which at its front is coupled to a stop

(6)

integral with the side edge of the plate (2) and which rests against the front face of the crossbar (4).

The coupling of the plate (3) to the stop (6) comprises anchoring means (7), elastically requested (such as the spring 10) that allow its separation (3 ') with respect to the stop for unlocking the device (figure 4). For this purpose, the stop (6) comprises a button (8) related to the anchoring means (7) to obtain, when pressed (8 '), the release of the device allowing the free rotation of the plate (2) along its axis (9) with which the plate can be placed

(2)

 in a folded arrangement practically aligned in the same plane determined by the stringers (4) (figure 2). The locking of the unfolded position of the plate (2) is achieved automatically, by recovering the spring (10), by turning it down until the stop (6) hits the crossbar (4) (figures 1 and 5).

A preferred case of application of this locking device is in a high chair where the plates would be two, one would constitute the seat and the other the footrest, and the stringers would constitute the front legs.

The invention, within its essentiality, can be carried out in other embodiments that differ only in detail from that indicated by way of example only, to which the protection sought will also be achieved. Therefore, this rotating plate locking device can be manufactured in any shape and size, with the most appropriate means and materials and with the most convenient accessories, the component elements being able to be replaced by other technically equivalent ones, as all of this is included within the spirit of the claims.

Claims (3)

1. Rotating plate locking device, which rotate transversely between two stringers, characterized in that it is arranged on each side of the plate and comprises therein a longitudinal plate therein which at its rear forms a support bending against the rear face of the stringer, and that on the front 5 is coupled to a supportive stop of the side edge of the plate and which rests against the front face of the crossbar. 2. Turntable locking device according to claim 1, characterized in that the coupling of the plate to the stop comprises anchoring means that are elastically requested which allow its separation with respect to the stop for unlocking the device. 3. Turntable locking device according to claim 2, characterized in that the stop comprises a button related to the anchoring means to obtain the unlocking of the device and the free rotation of the plate.
