Description

June 23, 1970 Y. DIVDRY CLIP Filed Oct. 24, 1968 United States Patent C II Yves Didry, 44 Avenue Paul Vaillant Couturier, Montreuil-sous-Bois, France Filed Oct. 24, 1968, Ser. No. 770,213 Claims priority, application France, Oct. 26, 1967,
26,01 Int. Cl. F16h 5/06 US. Cl. 287-18935 4 Claims ABSTRACT OF THE DISCLOSURE In one known system for assembling two metal section members without damage to their surfaces, a bracket in the form of a right angled member is clamped against the inner surface of each of the two metal section members by a spring clamping plate.
In this known system, bending of the spring strip enables the same to be introduced into the associated section member and provides the force for anchoring the terminal edges of the spring strip in the section member, by construction, however, spring strip width governs the internal dimension of the section member and angle-iron wall thickness, the internal dimension of the section member being the sum of spring strip width and angle-iron wall thickness.
This feature is a disadvantage for some constructions, since the three members which it is required to assemble together may differ in their dimensions for reasons of manufacture; consequently, a clip of the kind described is of use only for accurately dimensioned metal structures and cannot be used for assemblies of structures made of materials, such as concrete, which are associated with less dimensional accuracy.
Another disadvantage of such a clip is that an appropriate extraction tool must be used to remove the clip at disassembly.
The clip according to the invention obviates these two disadvantages, thus improving operating conditions and reducing building costs.
The clip according to the invention is embodied from round or square spring steel bent to form at least three arms-one central arm and two lateral arms-the ends of the lateral arms serving mainly for anchorage. The two dihedrons formed by the bending step between the central arm and the two lateral arms are of variable opening to help take up dimensional tolerances in the items which it is required to assemble.
The clip can be stressed in its bending plane and in a plane perpendicular thereto to provide a torsion giving improved anchorage of the ends of the lateral arms in the dihedron formed by the section-member lip with its adjacent plane.
The plan size of the clip according to the invention varies in inverse proportion to its longitudinal extent, its minimum plan size corresponding to the clip being c0mpletely flati.e., to the shape of the round or square spring steel stock before the same is bent to form the three arms. Between this minimum size and the siZe ice in any operative position, the clip automatically adjusts itself to a shape causing the central arm to bear in the right dihedron of the connecting angle-iron and the ends of the lateral arms to be anchored in the dihedron which the section-member lip forms with its adjacent plane, the effectiveness of the clip resulting from the fact that its two ends are anchored by the load. However, the anchorage of at least one of the two lateral arms can be rendered temporarily inoperative by using an ordinary lever to separate the two ends of the lateral arms from one another. This feature makes adjustment very easy, enabling as it does the angle-iron to be slid relatively to the bearing section member without any need to withdraw the clip, the anchorage of which is restored immediately the two ends of the lateral arms cease to be separated from one another.
Details of the invention will be disclosed by the description, reference being made to the accompanying drawings wherein:
FIG. 1 is a perspective view of a section-member assembled with its connecting angle-iron with the use of the clip according to the invention in its preferred form of square spring steel stock, the central arm of the clip being trapezoidal in shape to spread the bearing load over the angle-iron;
FIG. 2 is an end view of the assembly shown in FIG. 1;
FIG. 3 is a perspective view showing the same sectionmember assembled with the same angle-iron but using the simplest embodiment of the clip according to the invention, the clip of this embodiment having three arms, the two lateral arms being of different lengths and inclinations;
FIG. 4 is an end view of the assembly shown in FIG. 3;
FIG. 5 is a perspective view showing the same sectionmember assembled with the same angle-iron but using an embodiment of the clip according to the invention wherein one of the two lateral arms has a number of bends;
FIG. 6 is an end view of the assembly shown in FIG. 5;
FIG. 7 is a perspective view showing the same section member assembled with the same angle-iron but with the use of a clip according to the invention wherein the central arm is loop-shaped in order, as in the case shown in FIGS. 1 and 2, to spread the bearing load over the angle-iron;
FIG. Sis an end view of the assembly shown in FIG. 7.
In the drawings, a known form of section-member comprises three surfaces 13 and a lip 4; a known of con necting angle-iron comprises a plane 5 tangential to seetion-member surface 1 and a plane 6 tangential to sectionmember surface 2, the planes 5, 6 forming the sides of a right dihedron.
Referring to FIGS. 1 and 2, the clip has a central arm 7 which is in a trapezoidal shape so as to increase the bearing surface of angle-iron plane 5, the plane of the trapezium forming, before introduction of the clip into the section-member, a dihedron angle of with the plane of the two lateral arms 8, 9 of the clip, this dihedron becoming acute-angled after introduction into the section member; the two ends of the lateral arms become anchored in the dihedron formed by section-member lip 4 and the surface 3 adjacent lip 4.
Referring to FIGS. 3 and 4, the clip central arm 1 is simply recti inear so as to bear in the right dihedron of the angle-iron 5, 6.
Referring to FIGS. 5 and 6, one of the lateral arms of the clip comprises three bends 1012; the other items are unchanged as compared with FIGS. 3 and 4.
Referring to FIGS. 7 and 8, the central arm of the clip comprises a loop 13 which, as in the case shown in FIGS. 1 and 2, helps to spread the bearing load over angle-iron plane 5, the plane of the loop forming, before introduction of the clip into the section-member, a 90 dihedron with the plane of the two lateral arms 8, 9, such dihedron becoming acute-angled, as can be seen in FIG. 8, after introduction into the section member.
A clip of this kind is very easy to position, whatever the shape of its central arm may be, and it is self-removing immediately one of the ends of the lateral arms is raised above the lip 4.
What I claim is:
1. A clip for connecting two angled structural members one within the other, where one member is channel-shaped with a lip on one leg, comprising a bar of spring steel having a substantially greater length than its thickness, the bar having a central arm and two lateral arms being of different length and inclination than the central arm; a variable angle formed between the lateral arms and the central arm when the clip is inserted against the inner surface corner of a structural member; the ends of the lateral arms being anchored by the load in the dihedral which the lipped leg of the channel member forms with its adjacent plane.
2. A clip as defined in claim 1, wherein the bar of steel is round.
3. A clip as defined in claim 2, wherein the central arm forms a closed loop for frictional engagement in an oblique plane to the plane of the lateral arms and in a plane parallel .to the planes of thelegs of the channelshaped member.
4. A clip as defined in claim 1, where the bar of steel is square.
