Definitions

  • the invention concerns a method for the mounting of door fittings, for example a door handle rosette, on two opposite sides of a door leaf/door plate, in which door leaf/plate there is drilled at least one through-going hole, and comprising a fixing arrangement consisting of an elastic expandable material and comprising a hollow leg with a first outer diameter and with a first inner diameter in the formation of a cavity in the whole longitudinal axis of the leg, said leg terminating at each end in a first and a second end surface.
  • the invention also concerns a fixing arrangement for the mounting.
  • the mounting units are configured in a stiff, non-expandable material, which means that the pre-drilling must be effected with great accuracy.
  • a fixing arrangement for door rosettes and the like is known from German patent publication no. 2,615,322.
  • the fixing arrangement consists of two or three parts made of a plastic material, which are put together to form an assembled plastic part.
  • the arrangement comprises several loose parts, which means that it is difficult and troublesome to assemble in connection with the door rosette.
  • the plastic part will serve as a bracing stay, in that in its normal two-part version, where only one plastic part sits in each side of the door, no rigidity is achieved around the door handle fixture. In these cases there will therefore be a distinct "sponge effect" when a tightening of the plates towards each other is effected.
  • the fixing arrangement In connection with the use of the fixing arrangement, there is thus first carried out a clamping of the conical end of the fixing arrangement on the threaded stub which sits on the rosette, either integrated herewith or disposed loosely in a hole arranged for this purpose in the rosette. After this has been pressed in, the complete rosette is now set in place in the holes which are in the door. It is ensured that the length of the fixing arrangement corresponds to the thickness of the door, which can be done by cutting the fixing arrangement to a suitable size. It is thus characteristic that the fixing arrangement is a loose unit, for which reason the door fittings are produced smooth with holes for mounting, including mounting of thread-stubs, or with at least one integrated thread-stub on at least the one door fitting.
  • a rosette is then mounted from the other side, and a screw is now inserted through the holes in this rosette.
  • the screw used is a so-called trap-screw, which is characterised in that it has at least a thread in the one end, and under the head at the other end it has a further head with a diameter which is less than the outermost head, but still larger than the thread on the screw.
  • This trap-screw is inserted into the fixing arrangement, and when it meets with resistance, a screwing-in is effected. It is thus easy to engage the threaded stub on the other door rosette as a consequence of the screw being guided via the fixing arrangement.
  • the screw is screwed in to the bottom, and in that the screw is configured with said under-head, which is designated a "trap", an expansion of the walls of the fixing arrangement occurs, whereby these will expand out against the limiting surfaces of the hole. It is hereby ensured that the screw sits firmly in its attachment. Due to the through-going extent of the fixing arrangement, it is also ensured that a bracing between the door plates is effected.
  • leg in the other area has an outer diameter which exceeds the rest of the fixing arrangement, in that this ensures that the part which is placed over the stub and is subsequently inserted in the pre-drilled hole, sits tightly between the surrounding walls of the hole and the outer walls of the stub itself.
  • the fixing arrangement is a loose unit, i.e. it is not integrated with the door fittings.
  • the invention also concerns a fixing arrangement as disclosed in the introduction, and where the leg in the one end area - the plug-stub area - has an outer diameter which exceeds the first outer diameter, said plug-stub area extending from the first end surface of the fixing arrangement and for a given distance from this surface.
  • the fixing arrangement is particularly suitable for use in connection with the method as disclosed in claims 1-3.
  • the fixing arrangement according to the invention and as further disclosed in claim 5 there is achieved the forming of an area, the so-called thread-lock, where the result of the narrowing-down is that the screw will cut a thread in the elastic material.
  • the plug-stub area has some dimensions which are suitable in connection with the pressing-on of the stub of the door handle/rosette.
  • Fig. 1 shows a fixing arrangement 1 produced in an elastic and expandable plastic material, for example nylon.
  • the fixing arrangement comprises a leg part 2 formed as a cylinder and with an outer diameter 6 and an inner diameter 5, said inner diameter 5 forming a cavity 9 into which a screw can be inserted.
  • the leg part 2 of the fixing arrangement terminates in a second end surface 12 which extends substantially at right-angles to the longitudinal axis of the leg part.
  • the leg part continues over in a plug-stub part 10 which is similarly cylindrical in configuration, but its outer diameter exceeds the first outer diameter 6.
  • the inner diameter of the plug-stub part 10 is similarly larger than the first inner diameter 5, and is preferably conical in configuration with the largest diameter facing towards its end surface, i.e. the first end surface 11. This end surface extends parallel with the second end surface 12.
  • plug-stub part By configuring the plug-stub part as described, it is ensured that its outer diameter lies against the hole which is drilled in the limiting, surrounding surfaces of a door, and that the inner part is such that it fits the stub which is fastened to a door rosette/fitting.
  • the fixing arrangement also comprises an area in the leg part 2 which has a smaller diameter than the inner diameter 5, this inner diameter 13 being preferably 0.3 mm smaller.
  • a lock part i.e. that when the screw is inserted in the fixing arrangement via the cavity and starting from the second end surface 12, the screw will meet with resistance when it reaches the thread-lock part 4, which means that when the screw is rotated, the cutting of a thread is effected in the inner surface of the thread-lock part.
  • Fig. 3 shows a cross-section of the fixing arrangement 1 shown in fig. 1 seen from the one end, and where it will be seen that its outer surface is provided with so-called flukes 7, preferably four in number, which extend parallel with the longitudinal axis of the leg part and are displaced 90° in relation to one another. With these flukes it is prevented that the fixing arrangement turns when the screw cuts the thread in the thread-lock 4.
  • Fig. 2 shows the fixing arrangement 1 when this is mounted in a door, and thus the figure shows two door plates 14 extending in parallel and through which at least one hole 15 has been drilled, and where on the outer side of each door plate there is a door fitting 8, for example in the form of a door rosette.
  • the diameter of the hole is typically in the order of 8 mm.
  • a lock-casing 20 is inserted between the door plates. The mounting is carried out in that the one door rosette, on its surface facing towards the door plate 14, is provided with at least one threaded stub 3, and the fixing arrangement 1 is pressed with its plug-stub part down over the thread-stub part, so that this sits firmly on the rosette.
  • trap-screw 16 which is characterised in that the axis part comprises a tread part 17, and where the head part 18 in the area under the head has a so-called trap 19, said trap being characterised in that it has a diameter which is larger than the diameter of the thread itself, but is smaller than the actual head part.
  • the plug thus serves as a bracing stay, in that it increases the rigidity around the door handle fitting, and particularly in connection with doors of steel plate there is a distinct sponge effect which is prevented by the present invention.
  • the effect of the fixing arrangement is thus that the mounting of the fitting adapts itself to the holes which are pre-drilled in the door plate, said holes lying typically around 8 mm o/d.
  • the dimensions of the plug are thus preferably a length of approx. 75 mm, which is adapted to the relevant door thickness, an outer diameter 6 of 5.3 mm and an inner diameter 5 of 3.9 mm which, however, at the thread-lock lies at around 3.7 mm o/d.
  • the length of the actual plug-stub part is preferably 11-12 mm, and it has an inner diameter of 5.1-5.7 mm, in that as mentioned the diameter is changed when the inner cavity of the plug-stub part is conical in shape.
  • the fixing arrangement available for use with standard doors of 40 mm has a length just under 40 mm.
  • the flukes provided on the outer surface of the fixing arrangement 1 have a thickness which is typically 0.75-1 mm, and a height of approx. 0.2 mm. These are provided on the external side of the plug-stubs.
  • the plug can be used both in connection with "loose” polygon thread-stubs which are secured by polygon-shaped holes in the door handle plate/rosette, or in connection with bolt-welded thread-stubs.
