Abstract

A fastening device, e.g. for windows has a cover and a base plate. The base plate 10 has a sloping end 11 and straight end 12 and is provided with fixing holes 13 to receive screws by which the base plate may be fixed to a window frame. The base plate is also provided with a threaded bore 14 to receive a grub screw 15. The cover 16 has a dovetail shaped end portion 17 adapted to engage in the inclined portion 11 of the base plate 10. The cover 16 also has an end portion 18 adapted to engage over the corresponding end portion 12 of the base 10. In the cover is a countersunk bore 19 which received the grub screw 15. There is also a bore 20 through which a pivot pin 24 or rivet for a handle 23 may pass. The base plate 10 has upstanding walls which, when the cover is assembled on the base plate, conceal the sidewalls of the cover. A locking pin 25 extending from the handle can engage a bore in the top of screw 15. <IMAGE>

Description

SPECIFICATION Handle with locking cover This invention relates to fastenings of the type which employ a handle such as window fastenings and in which there is a cover to which the handle is attached and a base plate, for attachment to a fixed member or to a window for example, over which the cover fits.
An object of the invention is to provide a construction in which the cover can be held onto the base plate by a simple dovetail fixing at one end and by a single screw, such as a grub screw.
In accordance with the invention a fastening device comprises a base plate, a cover adapted to support pivotally a handle, and means for connecting the cover to the base plate comprising at one end a dovetail fixing and a single screw by which the cover may be held fixed in position on the base plate.
Preferably the end of the cover remote from the dovetail fixing is shaped so that is drops over the base whereby both ends of the base are concealed by the cover.
Preferably the base plate has a pair of upstanding walls running along its two longitudinal sides, the longitudinal walls, in use, concealing the edges of the cover.
It is preferable also that the grub screw contains a bore in its head into which a locking pin may be engaged so as to lock the handle to the cover and base plate when required.
In the accompanying drawings: Figure 1 is an exploded view, partly in section, of a base plate and cover embodying this invention; Figure 2 is a plan of the base plate and cover shown in Fig. 1; and Figure 3 is an elevation partly in section showing a handle in chain lines and a locking pin by which the handle may be locked to the base plate and cover.
As illustrated in Fig. 1 the base plate 10 has a sloping end 11 and straight end 12 and is provided with three fixing holes 13 to receive fixing screws by which the base plate may be fixed to a window frame or similar fixed structure.
The base plate is also provided with a threaded bore 14 to receive a grub screw 15.
The cover 16 has a dovetail shaped end portion 17 adapted to engage in the inclined portion 11 of the base plate 10. The cover 16 also has an end portion 18 adapted to engage over the corresponding end portion 12 of the base 10. In the cover is a countersunk bore 19 which receives the grub screw 15.
There is also a bore 20 through which a pivot pin or rivet for a handle may pass.
The base plate 10 has upstanding walls 21,22 which, when the cover is assembled on the base plate, conceal the sidewalls of the cover.
As shown in Fig. 3 a handle 23 is pivoted on a post 24 which passes through the aperture 20 in the cover 16. There is a locking pin 25 which may be moved axially downwardly so as to engage in a bore 26 in the grub screw 15. The locking pin is not shown in detail but may be, for example, of the type shown in our published UK patent specification 2146063A or in our UK patent application 8432512.
In use the base 20 is attached for example to a window frame 27 by means of countersunk screws and then the cover 16 with the handle 23 attached of course, is slid into the space between the upstanding walls 21 and 22 so that the dovetail member 17 engages the sloping end 11 of base 10. The end 18 of the cover is then engaged over the end 12 of the base plate and the grub screw 15 is then screwed through the countersunk bore 19 into the threaded bore 14.
Because the grub screw 15 is a countersunk screw it cannot be threaded too far into the bore as has happened previously with similar arrangements in which a simple grub screw is used.
The single grub screw fixing in combination with the dovetailed end 17 ensures that the cover is held firmly in position. When the handle 23 is in the position shown in Fig. 3 the grub screw 15 is covered by the handle and so cannot be removed. When the handle is locked in position by the locking pin the handle itself cannot be moved, the grub screw cannot be tampered with, and the hole assembly is secure.
Additional retaining pips may be provided such as pips 28 in the walls of the base which in assembly, engage in the cover. The process applied to the cover during assembly will cause the pips 28 to form depressions in the cover which cooperate with the pips to locate the cover.
