Abstract

TWO OR MORE COOPERATING BENT EDGES OF A PLURALITY OF SHEET METAL OR THE LIKE MEMBERS ARE RELEASABLY ASSEMBLED THROUGH THE USE OF A SINGLE OR MULTI-CHANNELED STIRRUP MEMBER WHICH STRADDLES THE BENT EDGE PORTIONS OF THE SHEET MEMBERS TO BE JOINED. A RESILIENT FLEXIBLE CLIP IS POSITIONED AGAINST ONE SIDE WALL OF THE STIRRUP DEVICE WITHIN ONE OF THE CHANNELS SO AS TO BIASINGLY ENGAGE THE BENT EDGE PORTION OF AN ASSOCIATED SHEET MEMBER THEREBY FORCING IT INTO ABUTTING ASSEMBLED RELATIONSHIP WITH A COOPERATING BENT EDGE PORTION OF A SIMILAR SHEET MEMBER WHICH MAY BE

ARRANGED IN COMMON OR PERPENDICULAR PLANE. THE STIRRUP DEVICE MAY HAVE ONE OR MORE CHANNEL MEMBERS DEPENDENT UPON THE SHAPE AND POSITION OF THE SHEET MEMBERS RELATIVE TO ONE ANOTHER AND UPON THE NUMBER OF CLIPS NECESSARY TO PROVIDE A BIASING FORCE ON THE BENT EDGE PORTIONS OF THE SHEET MEMBERS SO AS TO MAINTAIN THEM IN ASSEMBLED ABUTTING RELATIONSHIP.

FIXING ARRANGEIAENTS 5 Filed oct. 24, 196e' l l y 's sheets-sheet s 3,606,41 l Patented Sept. 20, 1971 Int. c1. 151611 /06 U.S. Cl. 287-189.36 6 Claims ABSTRACT OF THE DISCLOSURE Two or more cooperating bent edges of a plurality of sheet metal or the like members are releasably assembled through the use of a single or multi-channeled stirrup member which straddles the bent edge portions of the sheet members to be joined. A resilient flexible clip is positioned against one side wall of the stirrup device within one of the channels so as to rbiasingly engage the bent edge portion of an associated sheet member thereby forcing it into abutting assembled relationship with a cooperating bent edge portion of a similar sheet member which may be arranged in common or perpendicular plane. The stirrup device may have one or more channel members dependent upon the shape and position of the sheet members relative to one another and upon the number of clips necessary to provide a biasing force on the bent edge portions of the sheet members so as to maintain them in assembled abutting relationship.

This invention relates to a facility for the releasable assembly of two sheet-metal members whose juxtaposed bent edges are straddled by a stirrup clipped in position, the facility being distinguished by the combination of an appropriate shaped stirrup with one or two clips of the kindv which can compensate for dimensional tolerances and which connect the stirrup to one or both of the sheet-metal members.

Using a facility of this kind, which does not damage thevassembled sheet-metal members in any way, assembly and: disassembly can proceed in situ very rapidly and without tools and Without previous adjustments, so that the elements can be transported prior to assembly in a very small bulk and without any need to crimp the sheet-metal members with auxiliary section members, thus providing a very low-cost solution to the problem of providing assemblies using sheet-metal members.

Details of the invention will be disclosed by the description, reference being made to the accompayning drawings, wherein:

FIG. 1 is a perspective view, and FIG. la a view in horizontal section, showing the assembly of two sheetmetal members in alignment which form the base of a metal furniture item;

FIG. 2 is a perspective view and FIG. 2a a view in horizontal section of the assembly shown in FIG. 1 plus a third sheet-metal member which is perpendicular to the iirst and which forms a partition in the item of metal furniture;

FIG. 3 is a perspective view and FIG. 3a a view in horizontal vsection of a corner assembly using two sheetmetal members having the same edge lip;

FIG. 4'is a perspective view and FIG. 4a a view in horizontal section of a corner assembly using two sheet-metal members having different edge lips;

FIG. 5 is a perspective View showing the assembly of a side panel to a top panel;

FIG. 6 is a perspective view and FIG. 6a a View in horizontal section of a variant of the assembly of two aligned sheet-metal members;

FIG. 7 is a perspective view and FIG. 7a a view in section'of two aligned sheet-metal members comprising, as in FIG. 6, edge lips which nest in one another, and with the use of a single-channel stirrup member and a clip made of round or square spring steel known as piano wire, and

FIG. 8 is a perspective view and FIG. 8a a view in section of the assembly of two aligned sheet-metal members having larger edge lips so that clips can be introduced into the single-channel stirrup member from either side of such lips.

Referring to the drawings, two aligned sheet metal members 1, 2 form base elements and have the same edge lip and are dimensioned to receive a three-channel stirrup member 3 whose central channel straddles the two edge lips of the members 1, 2, the two lateral channels each receiving a clip 4 of a kind adapted to take up dimensional tolerances.

In `FIG. 2 a partition sheet 5 is introduced into one of the lateral channels before the positioning of the clip 4.

In FIG.3, the lateral sheet-metal member having the same edge lip as the base sheet-metal member is connected to the three-channel stirrup member 3 by a spot weld 6, assembly being by a single clip 4.

FIG. 4 shows a corner assembly between a lateral sheetmetal member 7 having an extra 90 bend and a base sheet-metal member 2, with the use of the same threechannel stirrup member 3 and tWo clips 4.

FIG. 5 shows an assembly between a vertical panel 8 and a top panel 9 with the use of an angle-iron whose vertical arm 10 is rigidly secured to the vertical panel 8 by a two-channel stirrup 11, a clip 12 which can take up dimensional differences also being used, the horizontal arm 13 of the angle-iron being rigidly secured to the horizontal panel 9 by a second two-channel stirrup member 11 and a second clip 12 of the same kind as the first clip 12.

FIG. 6 shows the assembly of two panels in alignment with one another; one panel, 2, has the same edge lip as has been shown in the previous drawings, but the other panel 14 has a reversed edge lip in which the edge lip of the member 2 engages, assembly being by means of a twochannel stirrup member 11 and a clip 4.

FIG. 7 shows two sheet-

metal members

2, 14 assembled in alignment with one another; the

members

2, 14 have edge lips which nest in one another. The assembly uses a single-channel mmeber 15 and a clip 16 made of round or square spring steel stock.

FIG. 8 shows the assembly of two sheet-

metal members

17, 18 in alignment with one another, the

members

17, 18 having relatively large edge lips for the introduction of securing clips; the assembly also uses a wide single-channel stirrup member 19 and two clips 4 of a kind adapted to take up dimensional tolerances.
