Device for fixing the escutcheon plate of handles and the like

Abstract

 Device for fixing the escutcheon plate of handles and the like comprising a sub-plate (1) which defines a cylindrical tang (3) which supports the handgrip (4) of a handle and can be accommodated in a through hole (21) defined in an escutcheon plate. The escutcheon plate has, at the lateral portion of its lower end, a threaded through hole (25) in which a threaded grub screw (26) can be inserted; the grub screw abuts against an abutment (30) defined at the lower end of the sub-plate in order to retain the escutcheon plate in position by means of the engagement of the through hole of the plate against the cylindrical tang and of the grub screw against the abutment.

Description

[0001] The present invention relates to a device for fixing the escutcheon plate of handles and the like.

[0002] As is known, the escutcheon plates of handles and the like are currently fixed to door- or window-frames by means of through front screws which connect the plate to the frame; the escutcheon plate rotatably supports the handgrip of the handle.

[0003] With this embodiment, the screws, arranged frontally on the escutcheon plate, create a rather unpleasant aesthetic effect which derives from the visible presence of the screws.

[0004] A principal object of the invention is indeed to eliminate the problems described above by providing a device for fixing the escutcheon plate of handles and the like which allows to stably connect the escutcheon plate to the door- or window-frame without the presence of front screws which are aesthetically unpleasant.

[0005] Within the scope of this object, a particular object of the invention is to provide a fixing device which allows to obtain a stable connection of the escutcheon plate while allowing to easily remove it if required.

[0006] Another object of the present invention is to provide a device for fixing the escutcheon plate of handles and the like which, by virtue of its peculiar constructive characteristics, is capable of giving the greatest assurances of reliability and safety in use.

[0007] A further object of the present invention is to provide a device for fixing the escutcheon plate of handles and the like which can be easily obtained starting from commonly commercially available elements and materials and is furthermore competitive from a merely economic point of view.

[0008] With these and other objects in view, there is provided, in accordance with the invention, a device for fixing the escutcheon plate of handles and the like, characterized in that it comprises a sub-plate which defines a cylindrical tang which supports the handgrip of a handle and which can be accommodated in a through hole defined in an escutcheon plate, said escutcheon plate having, at the lateral portion of its lower end, a threaded through hole in which a threaded grub screw can be inserted, said grub screw abutting against an abutment defined at the lower end of said sub-plate in order to retain said escutcheon plate in position by means of the engagement of said through hole against said cylindrical tang and of said grub screw against said abutment.

[0009] Further characteristics and advantages of the present invention will become apparent from the following detailed description of a preferred embodiment thereof, illustrated only by way of non-limitative example in the accompanying drawings, wherein:

figure 1 is a schematic plan view of the sub-plate;

figure 2 is a sectional exploded view of the device for fixing the escutcheon plate of handles and the like;

figure 3 is a view of the fixing device in assembled position.

[0010] With reference to the above figures, the device for fixing the escutcheon plate of handles and the like, according to the invention, comprises a sub-plate, generally designated by the reference numeral 1, which advantageously has an elongated body having, at its longitudinal ends, holes 2 in which screws 2a for fixing the sub-plate to the door can be inserted.

[0011] In a median portion, the sub-plate 1 is provided with a cylindrical tang 3 which rotatably supports the handgrip 4 of a handle.

[0012] More in detail, the cylindrical tang internally defines a seat 5 in which a gasket 6, arranged around the coupling tang 7 of the handgrip, is arranged.

[0013] A return spring 8 and a retainer plate 9 are furthermore connected to the tang of the handgrip; said retainer plate is kept in position by means of an elastic ring 10 which is coupled to the tang and retains the square pin 11 for the actuation of the lock.

[0014] A covering escutcheon plate 20 is applied over the sub-plate 1 and is provided, at a median portion, with a through hole 21 which is accommodated at the cylindrical tang 4.

[0015] A threaded through hole 25 is provided at the lateral surface of the lower end of the escutcheon plate 20, and a grub screw 26 engages therein; said grub screw abuts against an abutment 30 defined by the lower end of the sub-plate.

[0016] In this manner, the escutcheon plate is retained by virtue of the fact that, by tightening the grub screw, when said grub screw abuts against the abutment 30, in practice there is a pulling action on the escutcheon plate which makes the through hole 21 engage against the cylindrical tang 3, thus firmly fixing the escutcheon plate over the sub-plate.

[0017] With the described arrangement, there are no unaesthetic visible front screws, and support of the handle is furthermore not entrusted to the escutcheon plate but to the sub-plate, which is directly fixed on the door- or window-frame and the like.

[0018] From what has been described above it can thus be seen that the device according to the invention achieves the proposed aim and objects and in particular the fact is stressed that an extremely functional and practical fixing device is provided which allows to easily and rapidly remove the escutcheon plate simply by acting on the threaded grub screw 26.

[0019] In practice, the materials employed, so long as they are compatible with the specific use, as well as the contingent shapes and dimensions, may be any according to the requirements.

[0020] Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the scope of each element identified by way of example by such reference signs.

Claims

1. Device for fixing the escutcheon plate of handles and the like, characterized in that it comprises a sub-plate (1) which defines a cylindrical tang (3) which supports the handgrip (4) of a handle and can be accommodated in a through hole (21) defined in an escutcheon plate (20), said escutcheon plate having, at the lateral portion of its lower end, a threaded through hole (25) in which a threaded grub screw (26) can be inserted, said grub screw abutting against an abutment (30) defined at the lower end of said sub-plate in order to retain said escutcheon plate in position by means of the engagement of said through hole against said cylindrical tang and of said grub screw against said abutment.

2. Fixing device, according to claim 1, characterized in that said sub-plate has an elongated shape and is provided with holes (2) for the engagement with screws (2a) for fixing to the door- or window-frame and the like.
