Abstract

A door panel comprises front and rear metal panels 1, 2 formed and joined together such that a box- section portion 23 is provided on the hinge side of the door, and a wall portion 25 on the other, sufficiently wide to receive a lock. A flange 29 extends behind a part of the door frame 34, so that if hinges 32 are broken, outward movement of the door is prevented. <IMAGE>

Description

SPECIFICATION Sheet metal panel assemblies This invention relates to sheet metal panel assemblies, more particularly but not exclusively for use as doors for example for locks and cupboards.
According to the present invention there is provided a sheet metal panel assembly comprising first and second sheet metal panels, the assembly having a wall portion in which the panels are contiguous and secured together; a box section, the transverse walls of the box section being spaced apart by steps formed in one or both of the panels; and a marginal portion in which the panels are contiguous and secured together. Preferably the transverse edges of the panel assembly are formed into stiffening conformations, e.g. by folding them.
Embodiments of the invention will now be described by way of example with reference to the accompanying drawings, in which:~ Fig. 1 is a horizontal section through a locker door; Fig. 2 is a vertical section of the upper part of the door on the line A-A of Fig. 1; and Fig. 3 is a horizontal section through a second embodiment of locker door, hung on a doorframe.
The locker door shown in figs. 1 and 2 of the drawings comprises a front panel 1 and a rear panel 2 both formed from sheet steel. At the hinged side of the door (on the right in fig. 1) the front sheet 1 is bent rearwardly to form a hinge mounting edge 3 and again to form a stiffening flange 4. A reinforcing strip 5 may be mounted at the inner face of the edge wall 3.
The front panel 1 is bent, in its central region, through right angles, first rearwardly and then forwardly to form an inner (hinge-side) wall 6 and an outer wall 7, linked by a step 8. The outer wall 7 terminates in a forwardly-bent flange 9.
The rear panel 2 is bent, adjacent the hinge side of the panel, first rearwardly, then forwardly, to form an inner margin 10 and an outer wall 1 1, linked by a step 12. The wall 1 1 forms a back wall extending away from the hinge side to make contact with the wall 7 of the front panel 1, and is bent forwardly around the flange 9 of the panel 1 to form an outer flange or edge wall 14, which is bent around the forward edge of the latter to form a handle conformation 15 extending for the height of the door and having a reversely bent safetyedge formation 16.
It will thus be apparent that both outside edges of the front panel, and the outer edge of the rear panel, are formed into stiffening conformations.
The panels 1 and 2 are secured to each other by electrical resistance welds such as spot welds at positions indicated at X, i.e. between wall 6 and margin 10 and between walls 7 and 1 with the steps 8 and 12 transversely spaced. The door so formed includes a box section 17 on its inner hinge side, the panels being secured to each other at an outer wall portion and an inner marginal portion on either side of the box section.
To complete the door, the steps 8 and 12 (and possibly also the edge walls 3 and 14) are notched at their top and bottom ends to receive channel section rails such as 18 (fig. 2). The sides of the channel members, such as 19 and 20 are spot welded to the front and rear panels 1 and 2.
With this construction, a stiff perimeter frame is formed for the door and the latter is further reinforced by the box section consisting of the steps 8 and 12 and the portions of the front and rear panels 1 and 2 between them. A lock 21 can be readily secured to the rear panel 2 by poprivets 22 extending through both the front and rear panels, without the need for spacers since the two panels are in contact with each other in this region.
Suitable decorative extruded plastics strips can be fitted in the top and bottom channel section rails.
The second embodiment of panel assembly shown in fig.3, again exemplified by a locker door, again comprises front and rear panels 1 and 2.
The front panel I comprises a channel section 23 on the hinge side of the assembled door, between an inner (hinge-side) margin 24 and an outer wall 25. The front panel is formed by bending a flat panel forwardly, near its centre, to form the wall 25, bending the remainder twice rearwardly, to form a first step or outer channel wall 26 and then the channel base 27, and bending the remainder forwardly, to form a second step or inner channel wall 28 and a flange forming inner margin 24, parallel to the wall 25.
The rear panel 2 is flat across the width of the door and has an inner forwardly bent flange 29 and an outer forwardly bent edge wall 30 and handle conformation 31.
The front and rear panels are again spot welded (X) together with the wall 25 and margin 24 of the front panel contacting the flat rear panel. The channel 23 of the front panel, and the flat rear panel thus define a box section 17 separating an outer wall portion and an inner marginal portion.
Hinges 32, of which one is shown in fig.3, are mounted on the second step 28 of the channel 23 and on the opposite edge 33 of the door frame 34.
The door thus extends past the hinge and behind and beyond the edge 33 of the doorframe. This arrangement prevents the hinge side being forced apart by use of a jemmy and even if the hinge is worked loose the flange 29 will act as a locking bar to hold the door in behind the frame.
1. A sheet metal panel assembly comprising first and second sheet metal panels, the assembly having a wall portion in which the panels are contiguous and secured together; a box section, the transverse walls of the box section being spaced apart by steps formed in one or both of the panels; and a marginal portion in which the panels are contiguous and secured together.
2. An assembly according to claim 1 in which the outside edges of the panel assembly are formed into stiffening conformations.
