Description

System to move a panel for a built-in appliance or similar with functionality anti-crush.

The present invention relates to a system of  panel scrolling, provided with functionality adequate anti-crush to avoid or at least reduce substantially the risk of crushing the fingers during the panel movement. From now on reference will be made specific to a decorative panel for an appliance built-in and in particular to an installed appliance in a kitchen cabinet which wraps it completely (which is called "fully integrated"), while it is clear that that is said applies to any other similar application of a panel that moves level with other adjacent elements.

It is known that this type of decorative panels It is used to camouflage a built-in home appliance of way that matches the kitchen furniture. This is achieved applying to the door, by various means, a panel provided with the Same look as the other doors. This way there is no any visible element that distinguishes the device appliance of the other elements that make up the kitchen, its control being accessible only when the door is open.

In addition, below the panel applied to the door there is also a socket that acts as a bottom panel complementary to maintain the continuity of the coating while allowing the door to open. Examples of systems assembly and displacement of the lower panel or socket in which the socket is mounted through a parallelogram hinge fixed to the base of the machine itself and operated through a integral bar with the door, are set out in the European application EP-1380250 published and in European applications not yet published n ° 03425504.2 and n ° 04425132.0 all in the name of the same applicant.

Although functional, these solutions are not completely satisfactory since the systems described in these applications determine, during the closing movement, a risk of crushing the fingers in the cracks that they form between the panel and the adjacent elements. This risk depends in particular on the length of the drive bar of the system and the presence of corners along the edges of the panel and the elements adjacent to it.

Therefore, the object of the present invention is to provide a panel scroll system that overcomes the above mentioned disadvantages.

This object is achieved through a system in which the panel is mounted through a hinge of parallelogram and the rod that receives movement from the bar drive is divided into two elements joined by a spring.

The main advantage of the system displacement according to the present invention is the reduction substantial crushing of the fingers, which can be determine by properly adjusting the return spring that joins the two pieces of the articulated rod.

An additional advantage of this solution is that it You can apply as a replacement to any type of system known displacement, since it only involves the replacement of a rigid rod by an articulated rod provided with a return spring, without significant changes in cost or size.

These and other advantages and characteristics of displacement system according to the present invention will be made evident to those experts in the field from the following detailed description of two embodiments of the same, with reference to the attached drawings, in which:

Figure 1 is a schematic side view of a displacement system according to the invention in which the drive bar is attached to the upper rod; Y

Figure 2 is a view similar to the previous one showing a second embodiment in which the bar of drive is attached to the lower rod.

With reference to figure 1 it is observed that a displacement system according to the invention carries a panel decorative 2 arranged level between a decorative panel 1 of the door of a dishwasher and a panel of a reinforcement piece of the furniture (for example, the front face of a drawer).

This system includes a hinge of parallelogram comprising a lower rod 3, formed of so that it is mounted on the reinforcement panel and a top rod which in turn is composed of pieces 4 and 5. These rods are articulated on the base of the dishwasher through the respective fixed pins A and B, while their previous ends are connected, through the respective mobile pins A 'and B' to a plate carrying panel 2. A drive bar 7 is articulated through a pin I to the upper rod to transmit the movement to the system.

The novel aspect of the system according to the present invention is that it is provided with the rod "of drive ", in this case the upper rod, articulated because it is composed of pieces 4 and 5 articulated through the pin H and joined by a return spring 6.

More specifically, the back piece 4 of the rod is fixed on the machine through pin B, while the previous piece 5 is mobile and in turn is attached to the back 4 through pin H and spring 6 which is disposed between the rear end of the movable part 5 and the part fixed 4.

Thus, during the closing of the door illustrated in Figure 1, the crushing of the fingers both in the X position above the panel 2 and in the Y position below the panel 2 (in broken lines) is greatly reduced measured because the presence of an obstacle causes the movement of the movable part 5 around the pin H with the corresponding extension of the spring 6. In order to avoid the failure of the spring, an end stop (not shown) is preferably provided which limits the rotation of the mobile part 5, still guaranteeing an X or Y space of at least
12.5 mm

Obviously, a similar operation of the displacement system when the drive is achieved through the lower rod, as represented in figure 2.

The structure of the system is in fact similar, with a parallelogram hinge comprising a top rod 8 and a lower rod composed of parts 9 and 10. These rods are articulated on the base of the dishwasher through of the respective pins C and D, while their ends above are attached through the respective pins C 'and D 'to a plate carrying panel 2. A bar of drive 12 is articulated through a pin L to the Lower rod to transmit the movement to the system.

Since the "drive" rod in this case is the lower rod, it is said rod that is articulated since it is composed of pieces 9 and 10 articulated through pin E and connected through a spring return 11.

More specifically, the back piece 9 of the rod is fixed on the machine through pin D, while the previous piece 10 is mobile and in turn is attached to the back 9 through pin E and spring 11 which is disposed between the rear end of the movable part 10 and the fixed part 9.

Thus the crushing of the fingers both in the X position as in the Y position it is greatly reduced thanks to the rotation of the moving part 10 around the pin E with the corresponding spring extension 11.

Finally, it is clear that if both the rod upper as the lower are "drive" rods They have to be both articulated.

It is clear that the embodiment previously described and illustrated of the displacement system according to the invention is only a susceptible example of various modifications. In particular, the exact form and arrangement of the levers and pins can be changed slightly from according to specific needs, as long as it keep the type of scrolling described above on the panel 2 with specific anti-crush functionality.
