1963 J. H. LINDSTROM SUSPENSION DEVICE FOR CEILING BOARDS AND THE LIKE Filed July 21, 1958 JOHAN HARALD LIA/05mm,
DECEASED 5y OLOV LINDSTROM Aonzursreme By W M w w/ A O RAIL-V5 United States Patent 3,108,334 SUSPENSION DEVICE FOR CEILING BOARDS AND THE LIKE Johan Harald Lindstriim, deceased, late of Lidingo,
Sweden, by Olov Lindstriim, administrator, Nysatravagen 8, Lidingo, Sweden Filed July 21, 1953, Ser. No. 750,636 4 Claims. (Cl. 20-4) This invention relates to a suspension device for ceiling boards and the like.
The primary object of the invention is to provide a suspension device comprising two adjoining tongues or the like of resilient material which extend from a fastening means and have their lower free ends shaped into uniform, oppositely directed and substantially V-shaped projections which are adapted to cooperate with upwardly directed flanges extending from the edges of the ceiling boards. The suspension device according to the invention is characterized by the fact that the lower free limbs of the V-shaped projections are directed obliquely down wardly and have a length such that they cross each other so that upon insertion of the flanges of the ceiling boards the extremities of the projections will snap into recesses in said flanges from opposite sides of the flanges.
Further objects of the invention and the advantages thereof will become apparent from the following description, reference being had to the accompanying drawing which illustrates two embodiments, chosen by way of example, of the suspension device. In the drawing:
FIG. 1 is a front view of an embodiment of the suspension device with the ceiling boards mounted in position;
FIG. 2 is a side View thereof;
FIG. 3 is a front View of the suspension device according to a second embodiment with the ceiling boards mounted in position;
FIG. '4 is a side view thereof; and
FIG. is a vertical cross section of a ceiling as mounted.
With reference to the drawing the suspension device consists of an elongated open arcuate fastening means 1 and two identical pairs of substantially vertically extending tongues 2 of resilient material extending therefrom.
The two tongues 2 in each pair are arranged in side by-side relationship and diverge slightly from each other transversely of the elongation of the fastening means 1.
The suspension device according to FIGS. 1 and 2 is intended for use with ceiling boards 3 having their edges provided with upwardly directed flanges 4 of a relatively small dimension. At their lower free ends the two tongues Z are shaped into uniform, oppositely facing and substantially V-shaped convolutions 5 which are adapted to engage in recesses 6 in the flanges 4 of the ceiling boards 3 from opposite sides of the flanges. The upper parts 7 of the V-shaped projections 5 are substantially horizontal, extending from the divergent lower ends of the tongues 2, the parts 7 extending toward and past each other, and the lower parts -8 are directed obliquely downwardly toward and crossing each other, extending from the free ends of the upper parts 7. The transition between the parts 7 and 8 is rounded. Furthermore, above the l I l l l l l l l l a position opposite the recesses 6, they will snap thereinto. The upper substantially horizontally extending parts 7 of the convolutions 5 will engage with the upper edges of the recesses '6 so that the parts 7 will support the ceiling boards 3. Furthermore, the bent-out portions 9 will abut the upper edges of the flanges '4 so that the V-shaped convolutions 10 will grasp the portions of the flanges 4 lying above the recesses 6. The ceiling boards 3 are thus securely held by the V-shaped members .10.
When for some reason or other the ceiling boards 3 are to be taken down, this can be done simply by inserting a flat object, e.-g. a metal sheet, between the flanges 4. Said sheet will engage the downwardly directed parts 8 of the two tongues 2, moving said tongues apart whereby the convolutions 5 are disengaged from the recesses 6 in the flanges 4. The boards 3 can then be taken down without difliculty.
The suspension device according to FIGS. 3 and 4 which is intended particularly for use with ceiling boards 3a having relatively large flanges 4, differs from the embodiment in FIGS. 1 and 2 above only in that the tongues 2 have no bent-out portions 9 and consequently no V- shaped convolutions 10. In this case, however, the lower parts 8 of the V-shaped convolutions 5- are adapted to abut the lower edges of the recesses 6 so that the convolutions 5 will securely hold the ceiling boards 3a.
For mounting of the ceiling boards 311 one proceeds in the same manner as described above. [For taking down the boards no tool whatever is necessary, since the flange portion below the recess 6 may serve as a tool. By pushing one ceiling board 3a upwards the other ceiling board 3a can thus be removed.
The fastening means 1 consists of an elongated open arcuate hook member which is adapted to grasp a tubular member 12 mounted on the ceiling 11. The fastening means 1 being provided with two pairs of tongues 2, four ceiling boards 3 can be secured to the same suspension device. The recesses 6 in the flanges 4 have to be posi tioned at the adjoining corners of the four ceiling boards 3.
During the building of the ceiling a pair of, or possibly three or more, tubular members .13 are secured to the ceiling 11. These tubular members 13 which need not be exactly adapted to the length of the room, are arranged so as to be parallel to each other. 011 said tubular members 13 a plurality of tubular members 12 are laid at right angles to the tubular members 13 and spaced apart by the width of the ceiling boards 3. The tubular members 12 are secured to the tubular members 13 by wires or clamps 14 or the like so that the distances between the tubular members 12 may easily be adjusted. After that, suspension devices are secured to the tubes 12 and finally the ceiling boards 3 are fastened to said suspension devices. The walls 15 are provided with ribs 16 or the like on which the edges of the ceiling boards may rest.
While the invention has been described in two preferred embodiments in the foregoing specification, it is readily appreciated that the invention is not restricted to said embodiments as several modifications may be resorted to within the scope of the appendant claims.
What is claimed and desired to be secured by Letters Patent is:
1. A ceiling board installation, comprising a plurality of ceiling boards having upstanding flanges around the edges thereof and having apertures in said flanges, the apertures in abutting adjacent flanges being aligned, and a plurality of suspension devices each comprising a fastening means, at least one pair of resilient tongues depending from said fastening means, and oppositely facing V- shaped convolutions on the ends of said tongues, said convolutions having upper parts extending substantially horizontally toward and past each other and having lower parts extending obliquely downwardly toward and crossing each other, said V-shaped convolutions extending into said apertures and the upper edges of said apertures resting on said substantially horizontal upper parts to support said ceiling boards.
2. A ceiling board installation, comprising a plurality of ceiling boards having upstanding flanges around the edges thereof and having apertures in said flanges, the apertures in abutting adjacent flanges being aligned, and a plurality of suspension devices each comprising an elongated open arcuate fastening means, a plurality of pairs of resilient tongues depending from said fastening means, the tongues in each pair diverging from each other in a direction transversely of the direction of elongation of said fastening means, and oppositely facing V-shaped convolutions on the ends of said tongues, said convolutions having upper parts extending substantially horizontally from the divergent lower ends of said tongues toward and past each other, and having lower parts extending obliquely downwardly from the ends of said upper parts toward and crossing each other, said V-shaped convolutions extending into said apertures and the upper edges of said apertures resting on said substantially horizontal upper parts to support said ceiling boards.
3. A ceiling board installation as claimed in claim 2 in which said lower parts of said convolutions engage the lower edges of said apertures.
4. A ceiling board installation as claimed in claim 2 in which each tongue has a further V-shaped convolution between said fastening means and the lower end of said tongue, said further V-shaped convolutions each having a laterally extending portion engaging the upper edge of a flange.
