Patented June 6, 1939 SUSPENSION DEVICE Hermann Knig, Berlin-Schmockwitzwerder, Germany, assignor to C. Lorenz Aktiengesellschaft, Berlin-Tempelhof, Germany, a company Application August 12, 1936, Serial No. 95,507 In Germany August 15, 1935 v3Claims.
The invention relates to the means employed f on an aircraft, ship or vehicle :for suspending from a wall or ceiling apparatus which are sensitive to shocks, such apparatus as for example as radio apparatus. Such suspension is usually accomplished with the aid of springs` or elastic Y'straps or strings fixed to the sensitive apparatus i n and attached to projections of the wall or ceil- I ing by means of hooks or catches.
vThese arrangements have the disadvantage that the apparatus cannot be detached readily and that in addition the springs, straps or strings remain v y attached to the apparatus whenever this is detached, and will 'then be troublesome.
In the novel arrangement the elastic means oi suspension are xed to a frame which serves to apparatus to be protected from n ment. Fig. 2, drawn to a larger scale than Fig. 1,
represents a section on the line 2-2 of Fig. l, the plan 'View thus shown being partially sectioned. Fig. 3 represents a section on line 3-3 of Fig. 2.y Fig. 4 is aview of a certain portion of the frame intended for carrying the apparatus to be 'protectedl from shocks, this frame being shown completely in Figs. 1 and 2. Fig. 5 is a side View of Fig. 4. Figs. 3, 4, 5 are drawn to a slightly larger scale than Fig. 2.
A denotes an apparatus sensitive to shocks, which as shown in Figs. 1 and 2 is suspended yfromV elastic strings C by means of a frame B, Yin order to be protected from shocks. The apparatus A has recessed projections H adapted to receive the frame B, as represented in Fig. 3. i
'Ihe projections H have each a finger n. By `means of the lingers n the apparatus A is to rest upon frame B.
Frame B is made in two parts which are tubular and U-shaped and are slideably i'ltted together in the manner appearing from Fig. 2, so that they may be displaced with respect to each other. One of the two frame portions carries a lever D connected by a lever E with the other frame portion. K denotes the joint which is 5 common to levers D, E. As shown in Figs. 2, 4, 5 the levers D, E constitute a toggle device of the kind peculiar to the well-known bottle closures. Pivots F, xed to one of the two frame portions and carrying lever D, extend through longitudinal Slots G provided in the other frame portion. By moving lever D in the direction of the.V arrow in Fig. 5 the two portions of the frame B are shifted into one another andare thus caused to be engaged rigidly by the projections H. In order then to detach the apparatus A from frame B the lever D has to be moved in -the direction opposite to that shown in Fig. 5. The amount by which the frame portions are displaced with respect to each other is determined by the distance between the joints K and F and should be slightly greater than the tube diameter of frame B.
The round corners of the frame B are fitted with clips S to which the elastic strings C are fastened in any suitable manner.
What is claimed is:
l; In an apparatus sensitive to shocks, an open supporting frame for said apparatus composed of two U-shaped parts having their legs slidably fitted together, a toggle lever device for moving 30 said U-shaped parts with respect to each other to close and open said frame around said apparatus, and an elastic suspension for said frame.
2. An arrangement according to claim 1, wherein the said apparatus has recessed projections adapted to engage the frame.
3. An arrangement according to claim 1, wherein the said apparatus has a projection recessed to form fingers, one of which is longer than the other, to adapt it to rest upon said frame.
