Definitions

  • the present invention relates to a door handle assembly and more particularly to a device for mountins door handles on doors.
  • a door handle assembly generally comprises a pair of handles disposed one to either side of the door and mounted on a handle shaft which extends through a circular hole in the door.
  • a latch is installed in the door so that its bolt extends from the outer edge of the door and can be retracted by rotation of the handle shaft.
  • Tne handle shaft is mounted on a pair of mounting disks which are fitted concentrically on either side of the door about the circular hole through which the handle shaft passes.
  • the pair of mounting disks may either be connected by clamp means which draw the disks toward each other or alternatively each disk may be screwed to the surface of the door surrounding the aperture.
  • an escutcheon plate is arranged to be mounted over each of the mounting disks.
  • the escutcheon plate has an externally threaded boss which is sized to threadedlv connect with a complementary internally threaded boss on the mounting disk.
  • the escutcheon plate is attached to its respective mounting disk by rotating the escutcheon plate onto the threaded boss of the mounting disk.
  • the escutcheon plate serves to conceal the mounting disk and provides a more aesthetic appearance for the door handle.
  • One problem in fitting escutcheon plates to door handles has been that with continued use of the handle the escutcheon plate loosens from its mount on the mounting disk. Although this is not a serious problem it can be quite annoying to the user.
  • One object of this invention is to reduce this problem.
  • a door furniture mounting device comprising a pair of flat annular mounting disks, means to mount said disks on either side of the door concentrically about an appropriately sized aperture in the door, and a pair of escutcheon plates, each 0 escutcheon plate being arranged to be mounted on one of said mounting disks and whereby each said escutcheon plate is prevented from being inadvertently loosened from its mount on its respective mounting disk by first tongue means extending from the mounting disk or the escutcheon plate and engaging on a surface of the escutcheon plate or the mounting disk respectively when the 5 plate and disk are in a predetermined mounted relationship, to oppose relative loosening of the plate and disk from said mounted relationship.
  • the first tongue means extends from the mounting disk and is arranged to engage on an inside surface of the escutcheon plate.
  • the escutcheon plate is preferably threadedly connected to the mounting disk.
  • the first tongue means is preferably arranged so that when the escutcheon plate is rotated in order to mount it on the mounting disk the first tongue means frictionally engages with the inside surface of the escutcheon plate. With the continued rotation of the escutcheon plate the first tongue means bites harder into the inside surface of the escutcheon plate thus reducing the likelihood of the escutcheon plate loosening from its mount on the mounting disk.
  • an annular mounting disk and an escutcheon plate pair said escutcheon plate being arranged to be mounted on said mounting disk and whereby said escutcheon plate is prevented from being inadvertently loosened from its mount on its respective mounting disk by first tongue means extending from the mounting disk or the escutcheon plate and engaging on a surface of the escutcheon plate or the mounting disk respectively when the plate and disk are in a predetermined mounted relationship, to oppose relative loosening of the plate and disk from said mounted relationship.
  • a mounting disk for an escutcheon plate comprising a substantially annular mounting disk having attachment means for mounting an escutcheon " plate onto said disk and first tongue means extending from the mounting disk and arranged for engagement-with an inside surface of the escutcheon plate when the escutcheon plate is attached to the disk when the plate and disk are in a predetermined mounted relationship to oppose relative loosening of the plate and disk from said mounted relationship.
  • the first tongue means of each mounting disk comprises at least one tongue formed integrally with the disk and having a free end pressed away from the plane of the disk in a direction towards the escutcheon plate when the escutcheon plate is mounted on the disk.
  • the free end of the tongue points substantially in the same direction as the escutcheon plate is rotated in order to mount the escutcheon plate on the mounting disk.
  • the mounting disk has second tongue means.
  • the second tongue means comprising at least one tongue formed integrally with the disk and having a free end pressed away from the plane of the disk in a direction away from the escutcheon plate when the escutcheon plate is mounted on the disk.
  • the second tongue means being adapted to locate the disk concentrically of an appropriately sized aperture in a door.
  • Figure 1 is a horizontal cross-section through part of a door fitted with a latch and door handle assembly and mounting disk according to an embodiment of the invention
  • Figure 2 is a perspective view of a mounting disk according to an embodiment of the invention.
  • Figure 3 is a side view of a segment of the mounting disk shown in Figure 1.
  • Figure 1 shows part of a door 10 fitted with a latch 12, handle 14 and escutcheon plates 16.
  • Escutcheon plates 16 are of a conventional construction and their outer faces may have a decorative finish.
  • Each escutcheon plate 16 has centre opening 18 in which the handle is held captive and this opening 18 is surrounded by an inwardly projecting central boss 20.
  • Each escutcheon plate 16 also has an in- turned peripheral rim 22 so that an annular channel 24 is defined between the rim 22 and the boss 20.
  • the boss 20 has an external screw thread 26.
  • Each disk 28 has an essentially circular perimeter 30 and a circular central opening 32. Opening 32 is surrounded by an outwardly projecting central flange 34.
  • Flange 34 has an internal screw thread 36 so that the boss 20 of the escutcheon plate 16 can be screwed into the flange 34 of the mounting disk 28.
  • Mounting disks 28 are mounted to the door 18 in the conventional manner. Examples of typical mounting arrangements are shown in the applicants U.S. patent no. 4037865.
  • Each mounting disk 28 has a plurality of tongues 60 spaced about the circumference of the disk.
  • the tongues 60 extend in a substantially tangential direction to the circumference of the disk 28 and project upwardly above the surface 28a of the disk 28, in the same direction as which the flange 34 extends.
  • the tongues 60 are pressed from the disk 28 and preferably each tongue 60 has a pointed end 64 for engaging with the internal surface 66 of the escutcheon plate 16.
  • the pointed end 64 of each tongue 60 points substantially in the same direction as the escutcheon plate 16 is rotated in order to mount the escutcheon plate 16 on the disk 28.
  • the escutcheon plates 16 When the disk 28 and the latch 10 have been mounted to the door, the escutcheon plates 16 must be -mounted to their respective disks 28. This is done by simply rotating each of the escutcheon plates 16 onto the flange 34 of its respective mounting disk 28. As the escutcheon plate 16 is rotated onto the flange 34 and approaches the desired mounted relationship the internal surface 64 of the escutcheon plate 16 contacts against the ends 64 of the tongues 60. Continued rotation of the escutcheon plate 16 causes the ends 64 of the tongues 60 to bite into the inside surface 66 of the escutcheon plate 16. This contact between tongues 60 and the internal surface 66 eventually makes it very difficult to rotate the escutcheon plate 16 any further.
  • the escutcheon plates 16 are not likely to be inadvertently loosened from their position on each of their respective mounting disk 28.
  • the inside surface 66 of the escutcheon plate may be serrated in order to help the end 64 of each of the tongues 60 to grip onto the inside surface 66 of the escutcheon plate.
  • Each mounting disk 28 in addition to tongues 60 has a plurality of tabs 70.
  • Tabs 70 are formed integrally with the disk 28 and have a free end 72 pressed away from the surface 28a of the disk 28, in a direction opposite to that which tongues 60 are pressed. Tabs 70 extend in a substantially radial direction. Each adjacent tab 70 and tongue 60 pair define a recess 75. In the mounted position, the free ends 72 of the disk 28 engage against the wall of the handle shaft aperture . Alternatively, in doors where there is no large diameter handle shaft aperture and tabs 70 cannot enter the aperture, the tabs 70 can be deformed by engagement with the door face to allow the disks 2S to lie flat against the door face.
  • the previously described embodiment of the invention provides a simple and inexpensive way in which to ensure that the escutcheon plate 16 is not inadvertently loosened from the mounting disk 28.
