Definitions

  • This invention relates to developments in fasteners for windows and doors.
  • Fasteners for windows and doors are well known in the art in a number of designs.
  • the traditional design is a simple rotatable lever attached to the window which moves a rotational bolt into a recess in the window frame. These types are frequently made from cast metal although other methods could be used.
  • the rotational bolt is rotationally attached to a base plate by which the fitting is attached to a window.
  • a spigot extends from the rotational bolt for attachment to the handle.
  • a handle of this type is shown in Figure 1 .
  • the handle is usually fitted at the point of manufacture and is usually specified when specifying the windows.
  • the handle is chosen from the available designs. Due to the volume and throughput the window manufacturer usually has ample stock of the different available closure designs.
  • the handle is usually integrated with the fitting prior to assembly, often during manufacture, and the whole fitting attached to the window. An example of such a fitting is shown at Figure 2 .
  • top end window products in particular steel or aluminium framed windows that are design imitations of historic windows, but which are made to modern standards, it is often a requirement that the window handles are made to a specific, sometimes bespoke, design so as to maintain the character of the windows.
  • These windows are often required to be used when renovating historic or protected buildings where it is required to maintain the character of the building with minimum visual change.
  • These more bespoke type windows have the same or similar type espagnolette fasteners as other modern windows and the same types of fittings as shown in Figure 2 are usually used, albeit with a different visual appearance. Accordingly, aside from the standard modern handle designs that window manufacturers carry in stock, there may be many design variants, both in actual shape and in finish, from which the handle can be chosen for these specialised windows.
  • German patent application DE222439 , British patent application GB00028 , and US application US68956 disclose various methods of affixing door knobs or handles onto a tapered spindle extending through a door.
  • European application EP1321604 discloses a method of attaching a handle to a door or window leaf, the handle comprising a spindle and two projections which extend through the frame and receive fixing screws.
  • US application US2005/0156441 and Chinese Utility Model CN202380809 disclose handles for windows or doors, wherein the handle is retained on a boss plate by a circlip.

  • the internal shape of the tapered hole preferably conforms to the external shape of the taper on the pivotal shaft.
  • the tapered hole may have a chamfered inlet edge and the shaft may be provided with a corresponding chamfer at the base of the shaft.
  • the internal shape of the tapered hole preferably conforms to the external shape of the taper on the second end of the pivotal shaft and the tapered hole has a chamfered inlet edge.
  • the tapered second end of shaft may further comprise a chamfer at the base of the taper.
  • the fastener comprises the fastener body for attachment to the closure; the pivotal shaft extending through said fastener body, said pivotal shaft having the first end and the second end wherein the first end is located on the first side of the fastener body and the second end is located on the second side of the fastener body such that, in use it extends therefrom in a direction away from the closure; and the handle.
  • the first end is provided with the drive means configured to drive one or more latches to secure said closure, and the second end is provided with the taper for receiving the handle thereon.
  • the handle has the tapered hole therein for receiving said second end of the shaft and the internal shape of the tapered hole conforms to the external shape of the taper on the second end of the pivotal shaft and the tapered hole has the chamfered inlet edge.
  • the fastener comprises the fastener body for attachment to the closure; the pivotal shaft extending through said fastener body, said pivotal shaft having the first end and the second end wherein the first end is located on the first side of the fastener body and the second end is located on the second side of the fastener body such that, in use it extends therefrom in a direction away from the closure; and the handle.
  • the first end is provided with the drive means configured to drive one or more latches to secure said closure, and the second end is provided with the taper for receiving the handle thereon.
  • the handle has the tapered hole therein for receiving said second end of the shaft and the tapered hole has the chamfered inlet edge and the shaft is provided with the corresponding chamfer at the base of the shaft.
  • the handle can be provided with a keyway formed on the interior surface of its tapered hole.
  • the handle has a threaded hole therein between an outer surface thereof and the tapered hole, and wherein a screw is provided in said threaded hole.
  • the screw may be a grub screw.
  • the fastener of the invention may comprise a handle having a tapered hole therein for receiving said second end of the shaft, wherein the taper of the shaft is provided with a recess therein for receiving a further fastener; and wherein the handle has a threaded hole therein between an outer surface thereof and the tapered hole, and wherein a screw is provided in said threaded hole so that it extends through said tapered hole into said recess.
  • the threaded hole in the handle may be offset from, and overlap, the recess.
  • the screw may be provided with a tapered end and the threaded hole and the recess may be arranged such that tightening the screw through the threaded hole into the recess pulls the shaft into the tapered hole.
  • the fastener may further comprise latches and an espagnolette fastening device and said latches are driven by the handle via the espagnolette device.
  • FIG. 1 a traditional type window fastener 2 commonly used with metal framed windows is shown.
  • the fastener 2 has a base plate 4 by which it is attached to the window by screws via screw holes 6.
  • a post 8 extends from the base plate 4 and a handle 10 is connected to the end of the post 8 by peening 12 the end of the post 8 so that it fastens to the post 8.
  • the handle 10 has a latch 14 extending therefrom which interacts with a second part of the latch (not shown) that is located on the window frame so as to secure the window relative to the window frame.
  • FIG. 2 shows a traditional type fastener for use with an espagnolette type fitting 100, for example as used in uPVC type windows.
  • the handle 102 has an shaft 104 that is permanently attached hereto, for example by shrink fitting, expansion fitting, or push fitting, although other known fitting methods will be apparent to the skilled person, and which extends through a base plate 112 and which has a shaped end 106 that can drive an espagnolette type fitting.
  • the handle 102 is retained it the fitting by means of a circlip 108.
  • a retaining ring washer can be push fitted onto the shaped end 106 to retain the handle on the base plate 112.
  • the fitting is attached to the frame of a window during manufacture by screws (not shown) which pass through the attachment holes 110.
  • the fastener 20 has a body 22 for attachment to the closure part of, for example, a window or door.
  • a shaft 24 extends through the body 22 and is retained therein by a circlip 26 that fixes in a groove 28 of the shaft. In this way the shaft 24 is free to rotate in the plate 22. When fixed in place the shaft 24 passes through the body 22 so that it extends on both sides thereof.
  • One end of the shaft 24 is shaped in a substantially square shape 30 so that it may be received in a latch fitting, for example in a drive mechanism of an espagnolette type fitting, such that its rotation secures the closure, e.g. window, in a closed position.
  • a latch fitting for example in a drive mechanism of an espagnolette type fitting, such that its rotation secures the closure, e.g. window, in a closed position.
  • the end 30 of the shaft may have any shape suitable for driving in a rotary motion
  • the other end of the shaft is provided with a taper 32 on which is received a handle 34.
  • the taper is a machine taper, and may be a Morse taper.
  • the handle 34 has a corresponding internal taper 36 so that when placed on the shaft the two tapers retain the handle 34 in place on the shaft. In this way, turning the handle will turn the shaft and activate the espagnolette or other latch type mechanism to allow the closure to be opened or closed.
  • the taper 32 may be provided with a key 38 that locates in a corresponding slot 40 in the interior of the tapered hole 36 in the handle 34.
  • the tapered end of the shaft 24 may be provided with a recess 42 therein and the handle 34 may be provided with at hole 44 so that a further fastener 46 can be passed from through the hole 44 to locate in the recess 42. In this manner the handle 34 is prevented from pulling away from the shaft 24.
  • Either the recess 42 or the hole 44 may be provided with a thread and the further fastener 46 may, for example, be a grub screw that fastens to the thread.
  • the fastener 20 may also include an espagnolette fastening device having a drive hole in which the end 30 of the shaft is received so as to operate the latches of the espagnolette type device.
  • FIG. 5 and 6 an alternative embodiment of the invention is shown. This embodiment is similar to that shown in Figure 3 and as can be seen the handle attachment by means of the machine taper is the same.
  • this is replaced with a cog 50.
  • the cog 50 not only retains the shaft 24, which is shorter in this embodiment, in the handle body 22.
  • the shaft 23 is shorter and as such does not extend beyond the body 22. Instead the cog 50 acts on a drive arm 52 to slide between two positions. In use the drive arm 52 will act on an espagnolette type fixture in the window frame to operate remote latches.
  • the shaft 24a has a taper 32a at one end thereof which is substantially square in cross section, as opposed to circular in the previous arrangement.
  • the handle 34a has a square tapered hole 40a therein for receiving the tapered end 32a of the shaft 24a.
  • a chamfer 54 is provided around the opening of the tapered hole 40a, and a corresponding chamfer 56 is provided at the base of the tapered section 32a of the shaft 24a.
  • base of the tapered section it is meant that the chamfer on the pivotal shaft 24a is provided at the end of the taper that is towards the first end of the pivotal shaft, as depicted in the drawings, i.e. the widest section of the taper.
  • the handle 34a is provided with a threaded hole 44 extending therethrough to open into the tapered hole 40a, in which a screw 46 is received.
  • the tapered end 32a of the shaft 24 is provided with a recess 42 therein into which the screw 46 can be tightened to retain the handle on the shaft.
