Jan. 19, 1965 R. VINCENS DEMOUNTABLE DOOR HINGE 2 Sheets-Sheet 1 Filed Oct. 15, 1962 Jan. 19, 1965 R. VINCENS DEMOUNTABLE DOOR HINGE 2 Sheets-Shut 2 Filed Oct. 15, 1962 I This invention relates to? cabinets of which the frame structure consists of metalframes made of sections of the i United States Patent:()

type described and illustrated in the US. Patent No.

' The aforesaid patent also contemplates the possibility of fitting doors on a rack of this character for converting same into a cabinet, and'to this 'end the rack receives at the four'corners of .its front face fittings constituting the i female elements of door-hinges which are adapted to receive the pins of the door-hinges. i 7

However, the doors thus mounted are objectionable inthat in their closed position they project from the front face of the cabinet and show relatively large Clearances along their outer edges, thusperrnitting the ingress of dust into the cabinet. i I a It is the essential object of the invention to provide an improved door mounting arrangement for collapsible metal cabinet according to the aforesaid patent, 'which is characterized in that two 'strips carrying the door hinge plates are secured respectively on the upper portion and on the lower portion of the front frame of the cabi- "net, and act as fillistered casings to these doors.

Other features of the door mountingarrangement ac- FEGURE 4, is a horizontal section taken upon the line IV1V of FIG. 3; q

FIGURE 5 is a part-sectional View showing the device for locking one of thedoor hinges; and

FIGURE 6 illustrates thefltting of a beading on a door.

To facilitate the understanding of the present invention,-

only the upper strip of the cabinet will be described hereinafter, but it is clear that the lower strip is of similar design.

door hinges, so as to constitute the element of a fillistered casing for thes e doors. i

As shown in the figures, the hinge of each door is shifted outwardly from the main plane of the relevant door to permit an angular movement of about 270 of the door; thus, in the fullyopen position each door can engage the corresponding side post of the cabinet an free its front face completely. The 'lower flange of strip 1 has a hole 32 formed in the'vicinit-y of its outer edge and'overlying this hole is a welded inverted cup 8 constituting the female element of the door hinge. 7 Each door has;secured along its vertical outer'edge a channel section 9 vhaving a half-round bottom, this 'section protruding from the front face of the cabinet by a length correspondingsubstantially to the thickness of the side posts of the cabinet.

Fitted in the upper end of section 9 is a bushing 1 formed with a top flange 11 bearing on the upper end of this section. This bushing 10 is also formed with an axial bore 12 adapted to receive the male element 13 of the door hinge. This male element has a lower extension in the form of a rod 14 bent at right angles, the

outer; horizontal portion 15 ofthis rod extending rearwardlyand cooperating with a lock plate 16 secured on the door liner; to this end, this lock plate 16 has a U- shaped aperture formed therein (Fl-G. 5), the vertical base 17 of hisaperture being narrow enough to prevent the .sliding engagement of said bent portion 15 therein, and having a length corresponding to the stroke of the male element 13 from its retracted position to its engaged position in the female element 8; the two horizontal portions 19 of this aperture form therebetween a locking lug 26 the purpose of which will be explained presently; on the other hand, the width of eachho rizontal portion 19 permitsthe free sliding movement of rod 15.

The lower flange 6 of strip 1 is provided as usual with a door stop 22 and formed with notches 21 adapted to be engaged by the door espagnolette bolt.

The free edge ofthe lower flange 6 of strip 1 is also provided preferably with a plurality of notches 18 to facilitate the removal of this strip if desired, by inserting therein a screwdriver or other similar tool acting as a lever. t i

.The lower strip is exactly similar to the upper strip,

' except that it is mounted upside down, that vis, with its The strip 1 consists essentiallyof a channel section of a length equal to the width of the cabinet and of a width permitting the straddling of the upper cross member 5 of the front frame of the cabinet.

Theupper flange 2 of this strip haspunched lugs 3 formed in the vicinityof its free edge for snappily engaging the free edge of the upper flange 4 of said cross member 5; the free edge 31 of the lower flange 6 of strip 1 is bent upwards at right angles to'its plane so as to engage the free edge ofthe lower flange 7 of said cross member 5; thus, the strip 1 is locked on cross member 5 by the lugs ,3 and the bent portion of its lower flange, as shown in FIG. 3.

T 0 permit the engagement offlthe lower flange 6 of this strip under the cross member 5, the former is formed with notches 6a at either end, thewidth of each notch corresponding substantially to the thickness of the vertical side posts of the front frame of the cabinet.

When the strip 1 is anchored on the cross member 5 it projects from the cabinet front face by a distance corresponding substantially to the thickness of the doors and lower flange identical wtih the upper flange of the upper strip; preferably, the male element 23 of the lower door hinge is molded integrally with the lower bushing 24; otherwise, this bushing 24 is exactly similar to the upper bushing 16. n

Small plates 26 are secured on the ends of each strip 1 for occluding the section thereof which protrudes from the front face of the cabinet.

' The method of assembling this structure is clearly shown in the exploded view of FIG. 2.

Firstly, the upper strip 1 is fitted in position by anchoring its lower'flange 6 on the lower flange of the upper cross member 5 of the cabinet, then this upper strip 1 is'pushed home backwards until the punched lugs 3 on its upper flange are snapped in position for locking engagement with the free orinner edge of the upper flange 4 grease? 20 closed, thus lockinglsaid element 23 in its operative 1 impart a more pleasant appearance to, the cabinet, but in this case, it is'diificult to line also the channel members 24 are preferably made by. mold- 3. In a collapsible metal cabinet having a frame struc ture comprising two frames consisting of vertical upright sections and'horizontal transverse sections assembled by resilient mutual engagement and doors having section 9 of the doors'as described hereinabove and illustrated in the drawings.

'TAccordingto another feature characterizing this invention, these channel'members 9 may be covered by asuit- I ably' shaped beading adapted to conceal the vertical edge of the door lining. I

To this end, this beading 27 has a cross-sectional configuration corresponding substantially-to that of channel elements along their'edges and mounted by means of hinge pintl'es on the corners of thefront frame, and lateral and bottom panels, a pair of get-up strips secured respectively on the upperand lower transverse sections of the front frame,.each get-up strip consisting of a U-sectioned element of a length corresponding to the frame width, of a height permitting of straddling said transverse sections and of a depth exceeding the frame depth by a distance corresponding to the thickness of the door and their hinge pintles, one of the Wings of said element' having punched therein inthe vicinity of its free edge projections capable of engaging elastically from behind said free edge the member 9, and its outer flange is bent twice at right V angles inwardly, its free edge 28 being adapted to engage a vertical slot 29 formed to this end in the door.

. FIGURE 6 illustrates the fitting of this beading, which is simply threaded on the aforesaidichannel member 9.

Although the present invention has been described in conjunction with a preferred embodiment, it is to be understood that modifications and variations may be resorted to without departing from the spirit and scope of the invention, asthose skilled in the art will readily understand. Such modifications and variations are considered to be within the purview and scope of the invention. and
