Definitions

  • This invention relates to handles for windows or doors and also to a spindle for use with such handles.
  • Figures 1 and 2 show a conventional window handle for a window or door, which is conventionally manufactured from zinc or aluminium dye cast.
  • the handle has two main components in the form of a lever 2 to operate a spindle 7 and a rose 6, which is a fixed based that is fastened to the window opening sash that is to be operated.
  • the lever 2 and the rose 6 are typically joined by a riveting operation.
  • Within the lever 2 positioned coaxially with a point of rotation of the lever 2 is a cavity with tapered walls.
  • the cavity is arranged to receive the spindle 7 in a friction fit.
  • the spindle 7 is conventionally produced from an industry standard square section mild steel bar that is sized to pass through a spindle hub of a window lock operated by the lever 2.
  • the end of the spindle 7 that fits into the lever cavity mentioned above is typically reduced to a cylindrical profile which allows the spindle 7 to be mechanically press fitted into the lever cavity to form a tight interference fit, from which the spindle cannot generally be removed.
  • each window manufacturer will offer one or two profile (thickness) choices to their customers and provide correspondingly sized spindles that the customer will need with their chosen profile.
  • casement window handles are sold into the replacement market, typically through DIY stores. Most stores will only stock a small range of handles and will not provide a choice of spindle length for the customer. Consequently, a handle that has been purchased may not be suitable for the window system of the purchaser, because of an incorrect spindle length in relation to the window that it should fit, which leads to the customer returning the handle to the store.
  • a spindle for use with handles for windows and doors, the spindle comprising a head section having first abutment means adapted to abut corresponding second abutment means of the handle with which the spindle is to be used, wherein the first abutment means are adapted for axial abutment with the second abutment means.
  • the first abutment means are preferably located at an end of the spindle, preferably on an end face of the spindle.
  • the first abutment means are preferably include locking means, which may be clip means.
  • the first abutment means may be retaining means, adapted to retain the spindle at the corresponding second abutment means.
  • the second abutment means may be a locking member, which may be a locking pin.
  • the first and second abutment means may be adapted for inter-engagement with each other.
  • the spindle is preferably adapted to be received in a cavity of the handle, preferably in a tapered cavity.
  • the spindle may comprise a tapered neck section, which may be adapted to be received in a cavity of the handle.
  • the spindle may comprise a body section adjacent to the neck section, the body section being adapted in use to extend away from the handle.
  • the spindle may comprise a shoulder section between the neck section and the body section, wherein the shoulder section is preferably adapted to abut an exterior of the handle.
  • the spindle may be made of a plastics material, preferably a reinforced plastics material, reinforced with one or more fibre, wherein the fibre may be glass.
  • the plastics material may comprise a polymeric material.
  • the plastics material may be selected from one of the following: polyester, polyamide, polyurethane, polyacrylate, polystyrene, polycarbonate, polyalkene, preferably polyamide, which is preferably nylon, or may be glass-reinforced nylon.
  • the elastic properties of plastics material are advantageously used to allow the first abutment means to removably attach to the second abutment means.
  • the spindle may include a reinforcing insert that may be internal to a body of the spindle.
  • the reinforcing insert may be metal and may have an angled cross-section, which may be an obtuse angled cross-section.
  • a handle for windows and doors comprising a handle section for operating a lock and a cavity for receiving a spindle adapted to extend into the lock, the cavity being adapted to receive the spindle and comprising second abutment means, wherein the second abutment means are adapted for axial abutment with first abutment means of the handle.
  • the first abutment means are preferably located at an end of the spindle, preferably on an end face of the spindle.
  • the first abutment means are preferably include locking means, which may be clip means.
  • the first abutment means may be retaining means, adapted to retain the spindle at the corresponding second abutment means.
  • the second abutment means may be a locking member, which may be a locking pin.
  • the second abutment means may extend across the cavity, preferably from sidewalls thereof.
  • the first and second abutment means may be adapted for inter-engagement with each other.
  • an assembly comprising a handle for windows and doors and a spindle, the handle comprising a handle section for operating a lock and a cavity for receiving the spindle, which is adapted to extend into the lock, the spindle comprising a head section having first abutment means adapted to abut corresponding second abutment means of the handle, wherein the first abutment means are adapted for axial abutment with the second abutment means.
  • a kit of parts comprising at least one spindle as described in the first aspect of the invention and at least one handle as described in the second aspect of the invention.
  • Figure 3a shows a handle mechanism 8 for a window or door, which comprises a lever 10 and a rose 12.
  • the lever 10 is journalled in the rose 12, typically by spin-riveting techniques, to allow for relative rotation between the two to operate a lock mechanism (see 54 in Figure 7 ) located in a window opening sash 50 to which the handle is in use attached.
  • the handle 8 also incorporates a lock mechanism 14 that allows the lever 10 to be locked to the rose 12.
  • a spindle 16 is located in a tapered spindle receiving cavity 18, also known as a core, of the handle 8.
  • Openings 20 are provided in the rose 12 to receive fixings (not shown) to allow the rose 12 to be fixed to a window opening sash 50.
  • the lever 10 is assembled with the rose 12 by means of a rivet form 22 at a base part of the lever 10 as it emerges from the rose 12. Similarly, an enlarged section 24 of the lever above the rose 12 ensures that the lever is retained on the rose 12.
  • the spindle 16 is secured in the spindle receiving cavity 18 by means of a friction fit and also by means of a steel retaining pin 26 which is received in a semi circle clip section 28 located on an end of the spindle 16.
  • the spindle 16 comprises the semi circular clip section 28 and also a neck section 30, together with a body section 32.
  • the neck section 30 is tapered towards the clip section 28 at a draft angle corresponding to a draft angle of the spindle receiving cavity 18 to allow for a good friction fit.
  • the neck section 30 has a generally square shape with chamfered corners. This cross-section allows for good transfer of torsional forces between the lever 10 and a lock mechanism 54 that is operated by the lever 10.
  • the length of the body section 32 is chosen to ensure proper engagement thereof with the lock section 54 of the window opening sash 50 to above.
  • the semi circular clip 28 is secured to the retaining pin 26 by a push fit action.
  • the steel retaining pin 26 is received in openings 34 on either side of a spigot 36 of the lever 10 that projects into the rose 12.
  • the steel retaining pin 26 is received in the openings 34 in the spigot 36 by means of an interference fit.
  • the spindle 16 may be made of glass-reinforced nylon and may have a strengthening metal insert 17 (see Figure 6d ) running inside the spindle 16 along the length thereof.
  • the insert provides additional torsional stability.
  • an intermediate plate 38 which incorporates an opening 40 through which the spigot 36 of the lever 10 projects into a corresponding opening 42 of the rose 12.
  • the intermediate plate 38 also incorporates a catch element 44 for engagement with the lock mechanism 14 in the lever 10.
  • openings 46 for receipt of the steel retaining pins 26 are present in side elevations 48 of the intermediate plate 38.
  • the spindle 16 With the steel retaining end 26 in position in the lever 10 the spindle 16 can be pushed into engagement with the lever 10 until there is an interference fit between the neck section 30 and the spindle receiving cavity 18 and the semi circular clip 28 is secured to the steel retaining pin 26.
  • This arrangement of the spindle 16, which has a well defined neck section 30 with the semi circular clip 28, allows for precise location of the spindle in relation to the lever 10 and rose 12. This compares to the prior art method of a circular cross-section of spindle being pushed into circular opening in which an amount of engagement between the two is difficult to define because of the nature of the interference fit.
  • the benefit of the precise location of the spindle 16 with relation to the lever 10 and rose 12 is that the body section 32 of the spindle 16 extends away from the handle 8 to a well defined point defined by the length of the body section 32. It is the length of the body section 32 that extends into a window opening sash 50 to a point required by the Eurogroove position for the lock mechanism 54. Different thicknesses of window opening sash 50 require different lengths of spindle 16. Given that the relative positions of the spindle 16 and handle 8 are well defined in the example described above it means that the relative location of the spindle 16 with respect to the window opening sash 50 is also well defined.
  • the handle 8 has wide application in many types of windows and doors. This is because the same handle 8 can be used with a spindle 16 that has been specifically chosen for a given window or door. Thus, compared to the prior art, which required a specific handle and spindle pair, there is much wider application for the handle and spindle arrangement described herein.
  • a supplier can supply a handle 8 with a variety of lengths of spindle 16 to allow for the handle 8 to be fitted to numerous different sizes of window opening sash or door. In this way there are considerable reductions in redundancy of handle and spindle pairs, which could otherwise only be used in one thickness of window opening/or door.
  • a bespoke length of spindle 16 can be manufactured to the correct length.
  • the system described herein has the advantage that the spindle 16 is removable to allow the handle 8 to be used on a different thickness of window openings sash 50 or door.
  • the use of plastics material for the spindle 16 allows the clip 28 to be formed on the spindle and allows the clip 28 to function well and function in a repeatable way that is harder to achieve with metal spindles.
  • the invention takes into account current mass production techniques which takes into account the draft angle of the handle core detail.
  • the draft angle of the core detail provides the parallel walls that are matched on the tapered end of the spindle to provide a Morse taper type fit which is necessary to transfer the torsion loads from the spindle drive into the handle body.
  • the new invention is concerned with providing a handle which has interchangeable spindles that can be mass produced, economically.
  • the novelty comes from manufacturing a spindle from plastics material thereby utilising the principle of a mechanical clip property of the plastics material to engage the steel pin and thus hold it securely and positively in position within the lever cavity.
  • the spindle is proposed to be manufactured using over moulded steel reinforcement techniques to provide adequate mechanical strength to the spindle.
  • the additional novelty comes from utilising the draft taper of the lever core to produce a Morse taper type fit between the spindle and lever to provide a sound mechanical method of transferring the mechanical torsion loads.
