Description

HINGE STRUCTURE FOR THE ARTICULATION OF A TILTABLE SHUTTER TO A LOAD-BEARING SIDE WALL OF THE BODY OF A FURNITURE PIECE}

The present invention relates to a hinge structure for the articulation of a tilting shutter against a load bearing side wall of a furniture piece body.

This hinge structure applies in particular to, but is not limited to, the interior furniture sector, for example for the articulation of the tilt shutter of the kitchen wall unit.

Known tilt shutters are attached to the body of the piece of furniture via a pair of hinges attached to the inner side of the two pieces of furniture flanks.

Each hinge generally includes a joint quadrangle formed from a frame attached to a flank of the piece of furniture, and a pair of equalizers connecting the frame to the connecting rod and the connecting rod fixed to the shutter.

The hinge should be able to provide the possibility of separation from the piece of furniture body support surface by moving it relative to the shutter in the initial open phase relative to the support piece of furniture itself so that there is no interference between them during rotation.

The articulated rectangle of the known solution is generally designed such that the opposite sides generally have a similar size to function as a substantially joint parallelogram in the initial opening phase of the shutter.

The problem with this one hinge structure is its poor stability during its rotation.

In fact, since the configuration adopted for the joint rectangle is very similar to the joint parallelogram, the instantaneous rotation axis of the connecting rod draws a trajectory that is considerably far from the connecting rod itself.

Thereby, during the rotation of the shutter, the two rectangular portions may be subjected to non-uniform deformation so that the shutter is twisted.

Thus, in order to stabilize the shutter, it is necessary to connect the joint squares of the two hinges directly to synchronize the deformation, thereby preventing the undesirable twist of the shutter.

Nevertheless, this solution entails additional stabilizing elements, limiting the unused space inside the piece of furniture.

Therefore, the technical problem of the present invention is to manufacture a hinge structure for the articulation of the tilting shutter to the load bearing side wall of the main body of the piece of furniture, which eliminates the aggregated technical disadvantages of the prior art.

In the scope of this technical problem, one object of the present invention is to manufacture a hinge structure for the articulation of the tilted shutter on the load-bearing sidewall of the body of the piece of furniture, which provides the necessary stability for the shutter without the need for the use of additional stabilizing elements. It is.

Another object of the present invention is the articulation of the tilted shutter to the load-bearing sidewall of the body of the piece of furniture, in the initial opening phase, so that the optimum trajectory of the shutter is moved away from its support surface to prevent interference between them during rotation. It is to make the hinge structure of the dragon.

Another object of the present invention is to produce a hinge structure for the articulation of the tilting shutter on the load bearing side of the main body of a simple and compact piece of furniture as well as being efficient and reliable.

These and other objects as well as technical objects are achieved according to the invention by producing a hinge structure for the articulation of the tilting shutter against the load bearing side wall of the body of the piece of furniture according to claim 1.

Substantial similarity between the connecting rod and the frame in the closed position of the shutter ensures that the shutter is removed from its support surface in its initial open phase without interference between them, while a significant difference between the length of the connecting rod and the frame of the momentary axis of rotation of the connecting rod It should be noted that the trajectory remains close to the connecting rod itself, such that the hinge can provide the necessary stability to the shutter without using additional stabilizing elements.

Other features of the invention are further defined in the dependent claims.

Other features and advantages of the present invention are intended for illustration and are apparent from the description of the preferred but non-limiting embodiment of the articulating hinge structure of the tilted shutter on the load bearing side walls of the body of the piece of furniture according to the results shown in the accompanying non-limiting drawings.

Referring to the above drawings, the hinge structure 1 for the joint of the tilt shutter 2 is shown on the load-bearing side wall or the flank 3 of the main body of the furniture piece 4.

In particular, the furniture piece 4 has a bottom part 5, a rear part 6 and a cap 7 in addition to the right and left flanks 3 (only the left flank is shown).

The right and left flanks 3, the cap 7 and the bottom 5 are formed in the front part with a front support surface 8 for the shutter 2 in the closed position.

Two are needed for the articulation of the shutter 2 to the flank 3, but only one hinge structure 1 is shown (for the left).

It can be seen that the right hinge has a structure similar to the left hinge described in detail below.

The hinge structure 1 includes a joint rectangular portion formed by the frame 9 attached to the side wall 3, a connecting rod 10 fixed to the shutter 2, and a first hinge axis between the frame 9. 12 and a first balancer 11 having a second hinge shaft 13 with the connecting rod 10, a fourth hinge shaft 15 with the frame 9 and a fourth with the connecting rod 10. A second balancer 14 having a hinge axis 16.

The hinge shafts 12, 13, 15, 16 rotate in the open position of the shutter 2 between the closed position and the open position around the (horizontal) instantaneous rotational axis indicated by reference numeral 17 in FIG. 1. Are basically horizontal and parallel to each other (in FIG. 1, the construction lines are instructed to identify the momentary axis of rotation 17 in the open position of the shutter 2).

The first balancer 11 is located below the second balancer 14 in a common vertical plane and has a profile that matches the second balancer 14 that matches in the closed position of the shutter 2.

One of the important features of the present invention is that the distance between the first hinge axis 12 and the third hinge axis 15 is less than half the distance between the second hinge axis 13 and the fourth hinge axis 16, The plane 18 common to the first and third hinge axes 12 and 15 is substantially parallel to the plane 19 common to the second and fourth hinge axes 13 and 16.

In particular, in Fig. 1, the configuration taken by the joint rectangular portion in the closed position of the shutter 2 is shown in bold; In addition to the surfaces indicated by reference numerals 18 and 19, the surface 20 common to the first and second hinge axes 12 and 13 and the surface 21 common to the third and fourth hinge axes 15 and 16. ).

In addition, in FIG. 1, the dashed-dotted line is a trajectory 22, 23 drawn by each of the second and fourth hinge axes 13, 16 of the connecting rod 10 between the closed position and the open position of the shutter 2. ) Respectively.

Preferably, the distance between the first hinge axis 12 and the third hinge axis 15 is at least 1/3 of the distance between the second hinge axis 13 and the fourth hinge axis 16.

In the closed position of the shutter 2, the surface 18 common to the first hinge axis 12 and the third hinge axis 15, and the second hinge axis 13 and the fourth hinge axis 16 are common. The phosphor face 19 has an inclination of 0 ° to 12 ° with respect to the vertical plane parallel to the anterior support surface 8.

The frame 9 comprises a fixing plate 25 for the side wall 3 on which the elastic linear actuator 26 is mounted for operating the first balancer 11.

The elastic linear actuator 26 has a fifth hinge axis 27 for the stationary plate 25 and a sixth for the extension 29 of the first balancer 11 extending beyond the first hinge axis 12. It has a hinge axis 28.

In an advantageous manner, the elastic linear actuator 26 is arranged in a downward inclination from the rear part to the front part of the flank 3 and around the fifth hinge axis 27 from the open position of the shutter 2 to the closed position. Preferably has a limited angular range of up to 30 °.

This makes it possible to further limit the size of the frame 9 on the flank 3 of the piece of furniture 4.

The elastic linear actuator 26 more precisely consists of a gas spring, which is a cylindrical body 30 having a fifth hinge axis 27 with respect to the stationary plate 25 and an extension 29 of the first balancer 11. And a stem having a sixth hinge axis 28 for.

The extended end stop of the stem 31 from the cylindrical body 30 of the elastic linear actuator 26 determines the open position of the shutter 2, and at the open position of the shutter 2, the shutter 2 and the furniture piece It is designed so as not to generate interference between the caps 7 of (4).

The first balancer 11 also interferes with a known type of deceleration device 33 mounted on the stationary plate 25 in order to reduce the closing of the shutter 2 near the closing position of the shutter 2. It has a radial protrusion 32.

The vibration of the elastic linear actuator 26 is one side of the surface common to the fifth hinge axis 27 and the sixth hinge axis 28 common to the first hinge axis 12 and the fifth hinge axis 27. From the shutter 2 to the other side in the vicinity of the closed position. In this movement, there is an inversion of the direction of rotational moment exerted by the elastic linear actuator 26 at the first balancer 11.

In essence, during the initial opening phase of the shutter 2, the elastic linear actuator 26 generates a rotation moment discordant from the rotation moment applied by the user, but during the final closing phase of the shutter 2, the elastic linear actuator Numeral 26 generates a rotation moment in harmony with the rotation moment applied by the user to stabilize the shutter 2 in the closed position.

In addition, in the final closing phase of the shutter 2, the intervention of the deceleration device 33 prevents a strong collision of the shutter 2 with respect to the front support surface 8.

The hinge structure 1 of the present invention is a rotational moment generated in the first balancer 11 by the rotational moment generated in the first balancer 11 by the weight of the shutter 2 and in the opposite direction generated in the first balancer 11 by the elastic linear actuator 26. Between the moments, in every configuration taken by the joint rectangle, the first surface after the initial opening phase of the shutter 2 (ie, the surface common to the fifth hinge axis 27 and the sixth hinge axis 28 is the first After moving up and down the plane common to the hinge axis 12 and the fifth hinge axis 27), it is possible to create a substantially equilibrium.

In the first balancer 11 due to the change in the arm of the rotational force with respect to the first hinge axis 12 generated in the first balancer 11 by the elastic linear actuator 26 and the weight of the shutter 2. Between the change of the arm of the reverse rotational force with respect to the first hinge axis 12 which occurs, there may in fact be a substantial direct proportionality.

In fact, for the movement of the shutter 2, the user only has to apply enough manual rotational force to unbalance the substantial balance that the first balancer 11 receives.

Due to the fact that it imparts desirable stability to the shutter by maintaining an instantaneous rotational axis of the articulation square connecting rod proximate to the connecting rod itself, without employing additional stabilizing elements and preventing undesirable shutter distortion. It has been found that the hinge structure according to the invention is a particularly useful method.

The hinge structure of the present invention may all have various changes and modifications within the scope of the inventive concept, and all details may be replaced by technically equivalent details.

In practice, the materials used as well as the sizes may be in any format depending on the requirements and state of the art.
