' TOGGLE BOLT Filed April 10, 1942 i INVENTOR. 31/ 7035 fi/Wamr 4 T TOQNEY Patented Nov. 3, 1942 I umrao STATES. PATENT OFFICE Application April 10. im, Serial No. 438,359 Claims. (01.85-3) "This invention relates to toggle bolts and has for one of its objects the provision of an improved toggle bolt, which shall be constructed and ar-' ranged as to automatically accommodate itself to varying space conditions" found within walls where it is desired to use toggle bolts.

Another object of my invention is to provide an improved toggle bolt which shall be characterized by the simplicity of its construction and by the simplicity of the manner .of its use, and which at the same time shall be highly efficient in use and represent a general improvement in the art.

Other objects of my invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts which will be exemplified in the construction hereinafteridescribed and of which the scope of application will be indicated in the claims.

In the accompanying drawing, in which is shown various possible embodiments of this invention:

Fig. 1 is vertical sectional view through a portion of a wall construction with a toggle bo1t,.con structed in accordance with my invention, attached thereto;

Fig. 2 is an elevational view of the toggle bolt shown in Fig. 1, but illustrating the manner of attaching the same in position;

Fig. 3 is a cross-sectional view taken substantially along the line 33 of Fig. 2;

Fig. 4 is a vertical sectional view of a portion of a wall construction, similar to Fig. 1, but showing the application of a modified form of my toggle bolt constructed in accordance with my invention; and

Fig. 5 is a perspective view of the Fig. 4 form of toggle bolt.

Referring now in detail to the drawing I have shown in Figs. 1 to 3 a toggle bolt Ill constructed and arranged in accordance with my invention and effectively positioned in a wall. For purposes of illustration I have shown a wall structure comprising a front wall II, a rear wall I2 spaced therefrom and a cross support II of the customary materials employed in the art.

The toggle bolt of my invention comprises a frame I5 having a top wall I 50, side walls I5!) and end walls lie and I5d. Each of the side walls I5b is provided with longitudinal slotted openings I i. A block I1 is freely disposed within the channel of the frame II formed between the side walls Ilb. The said block I! is provided with projecting pins I. on opposite sides thereof which are freely slidable in the openings I6, so that the block I1 is held captively attached to the frame III and is slldably movable in the direction of the longitudinal axis of the said frame. The movement of the said block I! is limited by the end walls lid and IIib of the slots IS. The block I! is provided with a threaded opening I9 having its axis at right angles to the axes of the pins I8. Received in the opening I! is the threaded shank 20a of a bolt 20 having the customary enlarged head 20b. The top wall l5a of the frame I5 is provided with a slotted opening 2| and the end wall I5d is provided with a notch 22 extending upwardly from the bottom edge thereof. The purpose and function of the opening 2| and notch 22 will become apparent, in the following description of the manner of using the toggle bolt of my invention as above described. When it is desired to attach a member 21 to a wall, it is merely necessary to make an opening 25 in the outer wall I I sufiiciently large for the toggle bolt frame I5 to pass therethrough. The bolt 20 is first threadedly turned in the block I! until the bolt shank 20a touches the wall I50 and the pins l8 abut the walls I6b of the slots I6. This will maintain the frame I5 in a position with its longitudinal axis parallel to the axis of the bolt 20 and in which position the frame is passed through the opening 25. After this the bolt is unscrewed from its former position to its dotted line position (Fig. 2) until the frame I5, due to gravity, will pivot about the pins I8 and will automatically drop to the dotted line vertical position with the shank 20a of the bolt freely passing through the slotted opening 2I in the wall I in as shown in Fig. 2. While, in the last named position of the frame I5, the bolt is screwed inwardly in the block I! until the frame is held up against the inner surface of the wall I I to hold the member 21 in place.

It is thus seen from the above described construction that the toggle bolt of my invention will automatically adjust itself to whatever space conditions are met within the walls.- Thus, for example, in Fig. 1 I have shown a condition in which there is a cross beam I4 and for that reason it is noted that the frame I5 is in a higher vertical position with respect to the bolt 20 than tha shown in Fig. 2 which represents a condition where no such obstruction as the member I4 is present.

In Figs. 4 and 5 I have shown a modified form of my invention in which, instead of the frame I5, I'employ a simple flat plate of metal III or similar rigid material to which I attach a pair of spaced flexible wire members 3| and 32. The said wires 3| and 32 may be attached to the plate 30 in any suitable manner known to the art, such as, for example, by providing holes in the plate 30 into which the wire ends are received and held in position by solder (see Fig. 4). The plate 30 is provided with a threaded through opening 35 disposed between the wires 3| and 32. With this form of my invention a hole 36 is first made in the outer wall II and the plate 30 passed therethrough by first flexing the wires 3| and 32 so that they will lie parallel to the longitudinal axis of the plate 30, as shown by the dotted lines 3| and 32' in Fig. 5 of the drawing. After insertion the plate 30 is restored to vertical position, and in abutting relation with the inner surface of the wall II, as shown in Fig. 4, and with the wires 3| and 32 projecting through the opening 36. The plate 30 is thus held in position by pulling on the wires 3| and 32. While in such last named position the bolt 40 is threadedly passed through the plate opening 35 and the member 31 thus fastened in position. The wires 3| and 32 may then be clipped off, if desired, as in Fig. 4 or they may be left to project beyond the outer surface of the wall II to be utilized for hanging pictures or other articles thereon. In the latter case the member 31 may serve as a washer with openings to permit the wires 3| and 32 to pass therethrough.

If desired, instead of separate wire members 3| and 32, the said members 3| and 32 may be joined by a loop portion 38 (see Fig. 5) to provide a U-shaped member in which the free ends of the legs 3| and 32 are fastened to the plate 30.

It will thus be seen that there is provided a. device in which the several objects of my invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention I claim as new and desire to secure by Letters Patent:
