Abstract

Facing for a door frame having a case (16) extending on and into the door opening comprises a cladding member (18) securable to one side of the door case (16) and defining the rabbit (26) for the door (28) and a lining member (20) which is securable to the other side of the case (16) and connectable to the cladding member (18). The member 18 is secured to the case 16 by the studs 36 and has a web 48 adapted to engage ribbed incisions 46 in the member 20. The above facing is made of extruded plastics but in a modified arrangement are made of wood, laminated chip board, extruded plastics or drawn metal, see Figs. 3 and 4 (not shown). <IMAGE>

Description

SPECIFICATION Facing for a Door-frame The invention relates to facing for a frame secured in a structure for a room door or the like.

Facings for door frames are known. The known facings are placed on the door frames so that the rabbet is retained as a cavity. This means that the thickness of the facing plates has to be added to the thickness of the frame and the width of the door opening is correspondingly reduced. For the measurements of known facings, this lead to a 50 mm reduction in the width of the opening.

With is in mind, it is the aim of the present invention to construct facing so that, in addition to other advantages, the width of the door opening is reduced only slightly. This aim is achieved in that the facing according to the invention comprises two interlockable shaped members, one of which is a cladding plate which can be placed on the rabbet side of the old case on and in the rabbet thereof and contains the rabbet for the door panel whilst the other is a lining plate which can be placed on the depth of the old case. The rabbet of the old case therefore does not remain as a cavity representing loss of space but is filled by the facing according to the invention. This saves space and the door opening is reduced by only a minimum. A further advantage resides in the fact that the one lining plate is a shaped member covering the entire depth of the old case.As will be explained, this lining plate can be made of any desired width.

Hitherto, two shaped members had to be juxtaposed in order to cover deep door cases.

The cladding plate according to the invention comprises a longer limb and a shorter limb connected at right-angles to each other. The shorter limb is insertable in the rabbet of the old case and contains the rabbet for receiving the door panel. The shorter limb is provided with a locking web for engaging the lining plate and has a groove open to the rabbet for inserting a sealing lip. The facing according to the invention is secured to the old case by studs. In one suitable construction, the inside of the longer limb is provided with a ribbed aperture for pushing over the head of a stud or the like that is likewise ribbed. The individual facing plates can be adhered in position. For this purpose, spots of hot adhesive are sprayed onto the old door case at two or three positions. The facing plates of the invention are desirably extruded from plastics material.However, they can also be made from wood, chipboard, steel or aluminium. When extruded from plastics material, the longer limb of the cladding plate has a cavity extending through it longitudinally which surrounds a flat iron bar for stiffening purposes. The inside of the longer limb may also comprise a longitudinally extending recess for inserting a double-sided adhesive strip.

It has already been mentioned that the lining plate according to the invention can cover any desired depth of the door case. The lining plate of the invention comprises a plurality of juxtaposed individual members of modular dimensions, each module corresponding to the usual door case depth, and the individual members are easily separable from each other. The lining plate is therefore made or spread or extruded to a large width. It is severed into the individual members depending on particular requirements. The cladding plate according to the invention is 10 mm thick and the lining plate is 12 mm thick.

When using the facing according to the invention, the door opening is therefore reduced by only about 24 mm, compared with 50 mm hitherto.

The edges of the individual lining plate members contain grooves which are ribbed on both sides so that abutting members can be interconnected by inserted feathers. The ribbed grooves according to the invention extend over the entire width of the lining plate members and are interrupted only by individual transverse members. The individual members can therefore also be cut to the desired width outside the modular dimension and plugged together to the desired width by means of feathers.

It has been mentioned that the facing plates are preferably extruded from plastics material and could also be of metal or timber. For high requirements, they are made from timber or an angle member is extruded from plastics material and the exposed plates consist of timber or laminated chipboard. Preferably, attention is given to the same colour. In such a construction, the facing comprises a plastics angle member which is insertable in the rabbet of the old case and to which wooden cover plates can be applied.

The angle member comprises a rabbet for the door panel and a sealing lip which comes to abut the door panel. The cover plates are connectable to the angle member by a feather and groove joint. The edges of the cover plates can be covered by decorative angle bars.

Examples of the invention will now be described with reference to the drawing, wherein: Fig. 1 is a cross-section through one embodiment of facing applied to an old case; Fig. 2 is a section through the lining cover plate; Fig. 3 is a section through the second embodiment consisting of timber cover plates, and Fig. 4 is a section through a third embodiment comprising a plastics or metal angle member and timber cover plates.

Fig. 1 shows the masonry 12 with a plaster layer 14 and the old case 16. The cladding plate 18 according to the invention and the lining plate 20 according to the invention are placed over the two sides of the case 16. The cladding plate 18 consists of a longer limb 22 and a shorter limb 24. The shorter limb 24 is disposed in the rabbet of the old case 16 and itself comprises a rabbet 26 for the door panel 28. The door panel 28 abuts a sealing lip 30 disposed in a groove of the shorter limb 24. A flat iron bar can be inserted in a longitudinally extending cavity 32 of the longer limb 22. This serves to reinforce the entire facing.

A double-sided adhesive strip can be inserted in an incision 34 which is open to the inside.

However, in general mounting with the aid of studs will be sufficient. One stud 36 is illustrated.

It has a head 38 with a screwthread. An aperture 40 with ribs is pushed onto it. The cladding plate 18 also comprises a web 42 under which a cover plate is pushed.

The lining plate 20 is shown in more detail in Fig. 2. It consists of a plurality of individual members 44. The individual members 44 are identical and have a width of 320 mm. The lining plate is cut to size at the factory. This exposes the internally ribbed incisions 46. These are pushed onto the web 48 of tha cladding plate 18 that is visible in Fig. 1. Every depth of case can be covered by cutting the lining plate 20 to the desired width. Individual members 44 can be interconnected with so-called concealed feathers.

The embodiment shown in Figs. 1 and 2 is extruded from plastics material. However, for high requirements the timber embodiment of Fig. 3 is suitable. An angle member 50 is inserted in the rabbet of the old case 1 6 and itself contains a rabbet 52 for the door panel. A sealing lip 54 is disposed in the rabbet 52. A lining cover plate 56 and cladding cover plates 58 adjoin the angle member 50. They are interconnected by feathers 60. Angular decorative bars 62 cover the exposed edges of the cladding plates 58. The elements shown in this Fig. 3 embodiment are of wood or laminated chipboard. The cover plates can be secured to the old case by means of hot adhesive which is sprayed as spots on the old case.

Fig. 4 shows an embodiment in which the angle member 50 is extruded from plastics material or drawn from metal. In other respects, this embodiment corresponds to the Fig. 3 embodiment. The sealing lip 30 also engages over the lining cover plate 56 and covers its exposed edge.
