Description
A frame structure made of hollow members AKTIENGESELLSCHAFT FUR VOGT-PATENTVERWERTUNGEN C: 33912 The present invention concerns a frame structure comprising hollow1 members of polygonal cross-section, with at least one coupling unit interconnecting a pair of members.
Hollow frame members of metal and plastics material having a rectangular cavity cross section are used as components for a variety of constructions, such as frames for windows and doors, frameworks and the like. Hitherto many such structures have been screw connected or welded. Since in most cases small sub-assemblies or even individual fabrications are concerned, the final result involved considerable work and was costly.
Proposals for connecting the frame members by braced coupling units were unsatisfactory for various reasons. It was found, more especially, that in practice the dimensional tolerances of the hollow frame members were so wide that sufficient rigidity of standardised coupling units in the frames could not be attained simultaneously with adequate accuracy of joining.
It is an object of the present invention to provide a hollow frame member structure having internal expanding coupling units, which fulfil all normal and practical requirements and are cheaper than known structures.
According to the present invention there is provided a frame structure made of hollow members of polygonal cross-section, and having at least one coupling unit expanded into an end of a frame member, wherein the coupling unit has loosely interconnected flats braced in at least two directions in pairs against the inside surfaces of the frame member.
It has been found that certain hollow frame members marketed which normally are of rectangular or square cross-section have dimensions which diverge to a minimal extent from standard in a diagonal direction, but the dimensions of the flat inside surfaces may vary considerably. In order, therefore, in all cases to obtain an accurate position of the coupling units in such hollow members and hence a flush alignment of abutting section ends, it is preferable to ensure that the coupling units are located by supporting them from the corners of the hollow members. In a preferred embodiment of the invention, the flat parts of a coupling are positioned by elements the projecting shanks of which are provided with embossed grooves 10. Ribs 11 (Fig. 3) engage in this groove 10 to locate spreaders 12, so that these spreaders are secured to the shanks of the angle irons 2 and 3 and are displaceably mounted. As shown in Fig. 2, one spreader 12 is provided with a tapped bore to receive a spreader bolt 13» the tip of which engages in a recess in the other spreader 12. Detween the semi-cylindrical outer surfaces of the spreaders 12 and between the angle formed by each two abutting flats 2 - 5 a spreading cylinder 14 is loosely inserted. As indicated in Fig. 1, the two halves of the assembled coupling unit are initially held together by means of a self-adhesive tape bound 15.
A corner connection as shown in Fig. 1 is produced by mitre-cutting the hollow frame ends, whereupon a hole 16 to receive the spreader bolt 13 is bored by means of a jig on one side of each hollow frame member 1. The flat 2 is provided with a corresponding hole l6'. The unit assembled in accordance with Fig. 1 and Fig. 2 respectively is now inserted into one frame end. Then the bolt 13 is inserted and tightened. This forces the two central spreaders apart and the spreading cylinders 14 are pressed outwardly into the corners. This locates one leg of the unit formerly by the corners of a frame member. The positioning of all flats 2 - 5 is effected by abutment of the wires 8 against the most accurate parts of the hollow frame i.e. the corners. The flats 2 - 5 and wires 8 are so dimensioned that these parts when mounted in a frame engage in the hollow parts substantially without clearance, and the flats are of the correct size to be accurately located. At the same time a considerable spreading movement of each flat is is possible. Unevenesscs of the flat inside surfaces of the hollow members therefore do not affect the location of the coupling unit in the framework. After firmly locating one leg of the coupling unit in a hollow member 1, the other hollow member may be slipped over the other leg and located on the coupling in the manner described. It is, of course, also possible first to slip the two hollow members on to the coupling unit and then to insert the two spreader bolts and tighten them. possible for the coupling unit. The latter shape is suitable for use with special fittings such as hollow section members provided with fittings such as locks or strips.
The use of the parts 4 and 5 as shown in Figs. 1 - 4 has the advantage that all angles can be made of flat iron strip. In mass production it may be preferable to stamp the parts 4 and 5 from one sheet to avoid having to weld them together.
Corresponding parts in Figs. 5 to 7 are given the same designations , as in Figs.. 1 - 4. The coupling unit in this embodiment does- not connect two abutting mitred ends, but is fastened to one frame member and connects it with another member at right angles thereto. The two oppositely disposed flats 2' and 3' are joined together by a yoke 20 to form a U-shaped stirrup, which by means of self-tapping screws 21 is fastened to the frame member 22. The remaining parts correspond to the elements with similar designations in Figs. 1 - 4, except that in place of the semi-cylindrical spreaders 12, flat bars 12' with bevelled edges are provided. Between the spreading cylinder 14 and the flats 2' and 3' there are thin retaining plates 23.
As shown in Fig. 7» these effect exact location positioning of the parts 8 and 14 when these are connected to form a unitary structure by means of one of the loose flat bars 4 and 5 respectively, and are held together by adhesive tape 15 at one or two points. The coupling action corresponds to that shown in Figs. 1 - 4 and requires no detailed description. During assembly the stirrup 2, 20, 3' is first screwed in position, then two prepared units as shown in Fig. 7 are inserted from the side, then the member 1 is mounted and finally the screw 13 introduced.
Fig. 8 shows one use of coupling units in accordance with Figs. 5 - 7, six such units being screwed to the surfaces of a cube to connect up six frame members.
Fig. 9 shows an alternative embodiment for particularly narrow frame members. In place of the usual two spreaders only one spreader 12' is rovided which acts on two spreading cylinders 14. These brace the flat 35750/2 - 6 - whilst screw 13 presees the flat 2 against the inner wall of the frame member Further embodiments are also possible. Instead of positioning elements in the form of loose wires joined to the parts 4 and 5» they may, if necessary, form an integral whole therewith. Thus flats 2 - 5 may be used the outer edges of which, like the wires 8, engage withou 'clearance in the corners of the hollow members 1. This is possible only if the edges are part cut away so that Only individual positioning toeth remain, the positioning teeth of the flats 2 and 3 engaging in gaps between the positioning teeth of the flats 4 and 5.
The hollow frame members may have cross-sections which are polygonal, e.g. triangular or hexagonal.
The parte 8, 12 and 14 may be displaceably held together in cages instead of by means of adhesive tape, so as to facilitate assembly. These parts may also have different croes-sections from those shown. It is also possible to combine two spreading cylinders 14 by a resilient inwardly curved bridge, the spreading force of the screw 13 acting on the apex of this bridge. In this case the two parts. corresponding to the cylinders 14 and the bridge connecting them may be formed integrally as an extended section or stamping. .
The frame structure may also comprise inner carrying hollow members for instance of steel and. outer hollow covering members for instance of aluminium or plastics material slid thereon. As an example the inner hollow member may have a cross section as shown in Fig. 6 and may be enclosed by any suitable outer hollow member. Preferably, the inner hollow member may be slotted for instance in the corners of its profile within reach of the spreading cylinder's 14, the inner member being thus slightly spread when the bolt of the coupling unit is tightened. The inner hollow member is thereby pressed against the outer profile for securing the same in the desired position. The outer hollow member has holes for inserting and tightening the screws 13. This modification of the frame structure also allows simple and cheap manufacture in that hollow members may be shifted into each other and interconnected by means of coupling units.
