Description

technical field

This utility model relates to a handle for panels, more precisely, a retractable handle.

The retractable handles are concealed handles, i.e. handles that have a recess inside the door to accommodate a handle body for moving the door.

Typically, such handles consist of an internally hollow parallelepiped-shaped body, which is internally equipped with locking and actuating elements of the locking body, which can be pulled out for the intended movement. To attach such a handle to the panel, the frame is attached to the panel and the handle is attached to it with the help of perimeter screws.

In particular, a retractable handle is known which has an outer housing frame for supporting a handle and a latch, between the handle and the latch there being a shaft rotatably mounted on the housing and non-rotatably in the handle to permit opening and to allow the latch to be closed by the handle, the housing having interior walls that project from one another, the shaft including first and second drive bushings, each of the drive bushings having three distinct circular sections for mounting in circular apertures, each of the drive bushings having an inner and an outer end with the inner ends touching, the first drive socket having a pin protruding from the inner end, and the second drive socket having a passage through the pin to receive the pin and connect the sockets together.

As can be seen from the brief description above, this is a particularly complex product, the construction and assembly of which is very complex and takes a lot of time and money.

Therefore, the aim of the utility model is to produce an easy-to-assemble retractable handle in order to facilitate production and assembly and reduce costs.

This objective is achieved by a retractable handle for moving panels, characterized in that it consists of a main frame formed by a top plate perforated in two places with a rectangular profile of equal height and different length, where in one of the holes there is a gripping and moving element and in the other hole a flexible button connected to the plate by a connecting flap with elastic properties. Below the plate there is a pair of bushings located at the end of the screwed elements and a frame with a parallelepiped profile to match the cavity, the frame providing through holes at the end opposite the push button suitable for a pin for engage the gripping and moving element.

Other advantages are listed in the other descriptions, which better define the meaning of the solution chosen here.

Detailed description of the invention

The invented retractable handle consists of a front plate (1), on the surface of which two substantially rectangular recesses are provided for receiving a gripping and moving element (2) and a push button body (3) respectively, and a below the plate (1) pair of bushings (4) located in engagement with the wall of the panel or door to which the handle is attached. Also proceeds a frame 5 with a parallelepipedal profile, the frame (5) being provided with through holes at the end opposite the push button to receive a pin 6 for fixing the gripping and moving element (2) to the plate (1). the plate (1).

Ideally, the body of the push button 3 is connected to the plate 1 by means of a tab (7) designed to be flexible with elastic properties.

How from the 2 until 5 As can be seen, the push button body (3) consists of a flat plate on the underside of which an L-shaped lug (8) protrudes vertically, on the horizontal side of which a vertical tooth (9) directed towards the main plate is provided. A transverse trailing edge 10 is provided on the underside of the frame (5) level with the button body (3). The gripping and moving element (2) is connected to the push button body (3) via the pin (11). Use the screws (12) to attach the handle to the panel or door.

The sockets (13) arranged at the lower end of the plate (1) are used to accommodate the screws (12) and are connected to the housing and Gasket bushings connected. The housing and sealing bushings (4) ideally consist of a cuboid body in which a cylindrical bore is formed in the center, on one longitudinal surface of which a protruding V-shaped part (14) is removed, at the level of which - along the cylindrical wall - a elongate engagement groove is provided with a protruding pin provided on the connecting surface between the bushings and the body frame of the moving and gripping ring (2a).

Ideally, the engagement pin (6) has a torsion spring (16) whose leg ends are mounted on stops (17) located on the inside of the gripping element (2) or on one of the vertical walls of the frame (5) (the latter for reasons of readability not shown in the figures) are arranged.

The assembly is relatively simple: the operator mounts the gripping and movement ring - with the help of the locking bolt, which may be fitted with a torsion spring - on the frame and inserts the handle body into the hole previously made in the panel or door. He then inserts the sleeve into the bushings, creating a tight connection between the bushings and the frame, and bolts everything together. The gripping element is then held in the rest position by the engagement between the tine and the button so that the surface of the panel or door is flat.

When it is necessary to open the panel or the door, a push of the button is enough to release the moving and gripping element. If a torsion spring is provided, the gripping and moving element is brought into a comfortable position, e.g. as in 4 and 5 shown.

From the above description it is clear that the solution now described solves the previously encountered problems by producing a retractable handle that is easy to manufacture and assemble, which facilitates production and assembly and keeps costs down.

Although a particularly recommended embodiment of the invention has been concretely described here, there can be many analogous solutions that do not depart from the scope of protection defined by the accompanying descriptions.
