No. 293,529 Claims priority, appiieation italy Aug. 30, 1961 2 Claims. CL L20- 11) This invention relates to a frame of plastic for room doors, which is readily attachable to the door case previously anchored in its respective yaperture in a Wall thereby fully covering the junction of the plaster and case.
The main characteristic feature of the improved frame resides in the fact that the two uprights and top beam comprise each a channel-member of plastic (such as polyvinyl chloride) which engages by resilient deformation and snap action achoring means secured to the door case.
The invention will be described in detail with reference to the drawings, wherein:
FIG. l is a diagrammatical elevational View of a room door provided with the improved frame,
FIG. 2 is a cross sectional view of a channel-member of plastics forming the frame in its inoperative condition before assembly,
FIG. 3 is a cross sectional part-view on an enlarged scale on line IIL-III of FIG. 1, showing the frame in its assembled condition, and
FIGURES 4 and 5 are modifications of the structure shown in FIG. 3.
The frame for room doors comprises two uprights and a horizontal top beam, each made from an extruded channel-member of resilient plastics cut to length, the cross section of which in an inoperative condition before assembly is shown in FIG. 2. The channel member comprises a web section 1 and a pair of wings 2. An inwardly turned hook-shaped flange 3 is formed on the free edge of each of the wings 2. The web section 1 is formed with a step 4 imparting to the section a saw-tooth prole. The step 4 provides an abutment for a door panel.
I1 disassembled condition of the member the web section 1 is of a slightly inwardly bowed profile by an extent A with respect to the reference plane denoted by L connecting the corners of the member. The angles B formed by the wings 2 with respect to the plane L are smaller than 90.
Reference C denotes a wooden member of a door case cemented in a wall M, the latter being covered by layers I of plaster.
The anchoring means shown in FIG. 3 comprises a double frame formed by longitudinally extending anchoring strips 5 of pressed Wood fiber or the like, secured by means of nails or screws 6 to the opposite sides of the door case C to cover the junction between the case and plaster layers I. The two strips 5 are interconnected by a bridging strip '7 of plywood or pressed wood fibers whereby a kind of underframe is formed.
The strips 5 and bridging strip 7 are preferably secured to the door case C with the aid of a jig or model accurately reproducing the dimensions of the door frame.
The strips 5 are each undercut at 5a to provide a recess for snap engagement by the anges 3 on the channel member of plastic which is tted on the nnderframe and is resiliently deformed from its original shape to resiliently close around the strips 5 and bridging strip 7. In this manner the originally bowed web section of the channel member straightens up by the extent A whereby the step 4 finds a iirm support on the bridging strip 7.
Shims are preferably interposed between the bridging strip 7 and door case C at the region of the door hinges.
The assembly of the channel members of plastics on Patented Apr. 2S, 1964 ice the underframe is easily and readily accomplished even by unskilled workers.
According to the modiication shown in FIG. 4 the anchoring structure for the frame comprises a strip 11 of plywood or the like curved to a channel-profile substantially matching the inner shape of the channel member of plastics. The wings of the channel-formed wooden strip 11 are nailed to the case member C by means of nails 14 through interposition of shims 12 in the form of strips or spaced lugs providing between each of the edges of the strip 11 and plastered wall a recess 13 into which the respective hooked flange 3 snappingly engages on assembly.
According to the modification shown in FIG. 5 the anchoring structure comprises two wooden strips 5 and a bridging strip 7, as in the case of FIG. 3. An inward step 5a, 5b is formed in each longitudinal edge of each strip 5 and the outer faces of the latter are symmetrically rounded in cross-sectional prolile, as indicated by 5c.
The step 5a serves for anchoring the flange 3 of the channel member of plastic, the opposite step 5b having the bridging strip 7 bearing thereon, which may, if desired, be secured to the door case C by a number of nails 8.
The rounded portions 5c on the strips provide a dimensional allowance between the channel member of plastic and the underfrarne on assembly.
The whole cross-sectional profile of the strips 5 is advantageously symmetrical with respect to a mid-plane (as embodied by nails 6 in FIG. 5), whereby no trouble arises as to the right orientation of the strips on assembly.
What I claim is:
1. In combination with a door case member framing an aperture in a wall, an underframe structure providing a pair of continuous anchoring strips on opposite sides of the wall secured to and extending lengthwise of the member, said anchoring strips each having a recess along the edge thereof adjacent the wall, and an extruded channel member of resilient plastic iitted on the underframe structure, said channel member comprising a web section, a pair of wings integral with the web section each including an inwardly turned hooked ange engaged over the respective anchoring strip in the recess therein, and a saw-tooth-like step formed on the web section lengthwise of the latter providing a stop-abutment for a door panel; said wings being of a length equal to the width of the continuous strips, and said wings each forming an acute angle with the plane passing through the two corners of the channel member and said web section being inwardly bowed with respect of said plane in disassembled condition of the channel member with respect of the underframe structure, whereby the channel member is resiliently deformed in assembled condition and the anges are snappingly engaged in said recesses.
2. The combination defined in claim 1 wherein said anchoring strips are disposed in an arrangement to cover the junction between the door case member and the Wall, and -a bridging strip extending between said anchoring strips and rigidly secured thereto, the bridging strip providing a support for the web section of the channel member.
