Description

Invisible handle

Technical Field

The utility model relates to a be applied to the handle of door plant, specifically be an invisible handle.

Background

Invisible handles are well known products with a recess embedded in the door panel that receives a gripping element for moving the door panel.

Generally, such handles consist of a parallelepiped hollow inside, containing the bolt and means for moving said bolt, the latter being pulled out when it is desired to open or close the door panel. Such handles are typically secured to the door panels by the use of screws to secure the frame to the door panels.

Specifically, the invisible handles available on the market are mainly composed of a housing which can accommodate a handle and a plug. The handle and the bolt are fixed in the shell through the rotating shaft, and the bolt can rotate together when the handle rotates, so that the action of inserting or pulling the bolt is completed. The housing is formed by spaced side walls and the shaft is formed by two bushings, each bushing having three different circular cross-sections to facilitate free rotation thereof while being secured in the circular recess. The inner ends of the two bushings are mutually contacted when being installed, the inner end of one bushing is provided with a protruding thin rod, and the inner end of the other bushing is provided with a central opening for accommodating the thin rod, so that the two bushings are connected and fixed.

SUMMERY OF THE UTILITY MODEL

As can be seen from the brief description above, such pull handles are complex in construction, requiring a great deal of effort in construction and assembly, meaning a great deal of time and financial investment.

Therefore, the utility model aims at designing an invisible handle, which has the characteristics of easy manufacture and assembly and can reduce the production cost.

To achieve this object, we have designed a handle for door panels, characterized in that it consists of a main frame, the surface of which is a rectangular plate, on which two rectangular openings of equal width and unequal length are cut, one of them having a pull ring placed in it and the other having a push button placed in it, the push button being connected to the surface of the frame by means of an elastic connecting tongue, and being movable up and down. And a pair of sleeves capable of accommodating screws are arranged at two ends below the surface rectangular plate, and a parallelepiped frame corresponding to the opening is arranged. The frame is provided with a through hole at an end opposite to the button, and the through hole can accommodate a rotating shaft for fixing the pull ring.

Detailed Description

The invisible handle designed by the invention is composed of a front plate 1, two rectangular openings are arranged on the surface of the front plate, the rectangular openings are respectively used for accommodating a gripping element 2 and a button 3, and a pair of fixing bushings 4 are arranged below the front plate 1 and are used for fixing the handle and a door panel. Below the front plate 1 is a parallelepiped frame 5 integral therewith, said frame 5 being provided, at the end opposite to said push-button, with a through hole for housing a rotating shaft 6 which fixes said grip element 2 to said front plate 1. Attached to the front plate 1 under the surface of the gripping element is a ring structure 2a.

The preferred solution is to connect the button 3 to the plate 1 by using an elastic connection tongue 7, enabling the button 3 to move up and down.

As shown in fig. 2 to 5, the button 3 consists of a flat plate, under which there is an "L" shaped tongue 8, on the long side of which there is a thin rod 9 perpendicular to the surface of the button. A cross bar 10 for limiting the moving range of the button is arranged on the bottom surface of the frame 5 below the button 3. The grip element 2 is normally snapped together with the push button 3 by means of the projection 11. The screw 12 is used to secure the handle to the door panel.

Sleeves 13 at the lower ends of the front plate 1 are provided for receiving said screws 12, said fixing bushes 4 being able to form a stable engagement with said sleeves 13 thanks to the particular shape configuration of said sleeves 13 and of the portion of the frame 5 to which they are attached. In particular, in the preferred solution, the main structure of the fixing bush 4 is parallelepiped, with a longitudinal cylindrical opening inside, and "V" shaped slots 14 on the sides. The end of the frame 5 where the gripping element 2 is placed is connected to the sleeve 13 by means of a pin 15, the "V" shaped slot 14 of the fixing bush 4 being intended to engage with the pin 15.

In a preferred embodiment, the shaft 6 is provided with a torsion spring 16, the two ends of the torsion arm of which are fixed to detents 17, one of which is located on the inner surface of the grip element 2 and the other of which is located on the side wall of the frame 5 (the second detent is not shown for the sake of readability of the drawing).

This structure makes the assembly process relatively simple: the operator only needs to mount the gripping element on the frame through the rotating shaft (which can be provided with a torsion spring), and then the handle is integrally inserted into the preset opening on the door panel; then the fixed bushing and the sleeve are required to be tightly inserted and form stable connection with the handle frame, and finally the screw is screwed. Typically, the grip element snaps with its protrusion into the button, thereby maintaining the appearance of the door panel in a flat condition.

When the door panel needs to be opened, the gripping element can be released only by pressing the button. With the torsion spring, the grip element will be ejected to a position for convenient use, as shown in fig. 4 and 5.

From the foregoing, it will be appreciated that the present invention solves the problems described above, while also reducing production costs, by realizing a hidden pull tab that is easy to manufacture and assemble.

The solution described above is only a preferred embodiment of the invention, and many other variants are possible beyond this, without departing from the scope of protection defined in the appended claims.
