CEILING SUSPENSQION ELEMENT Filed March 18, 1957 INVENTOR Lloyd MQNoir ATTORNEY United States Patent O 2,951,279 CEILING SUSPENSION ELEMENT Lloyd L. McNair, 214 w. 901 St., Dallas, Tex.
Filed Mar. 18, 1951, Set. No. 646,738
1 Claim. c1. 50-468) This invention relates to a ceiling suspension element, and it concerns more particularly a device capable of being embedded in a concrete structure, such as an upper floor of a building, for use in suspending a ceiling, pipe or fixture therefrom.
An object of the invention is to provide a device for use with concrete or other ceilings, and by means of which suspension bars or rods for metal lath or other ceiling material may be quickly and economically applied.
Another object of the invention is to provide a device of the type described in which the suspending means for the rods or bars are so arranged that, when the forms for the concrete have been removed, no cavities will show or be left in the ceiling until such time that the device is utilized, when the exposed bottom surface is removed with a knife or other instrument, whereupon the suspending means will drop down into position to immediately receive the rods or bars.
Another object of the invention is to provide such a device which includes a piece of bent wire having a straight intermediate portion which, in its applied position, extends horizontally across a cylindrical cavity molded in the underside of the adjacent concrete structure and having a pair of upwardly and outwardly bent end portions which, in their applied positions, are embedded in the concrete and advantageously may be sup ported upon the reenforcing rods, and which also includes a loop of wire which loosely surrounds the intermediate portion of the first mentioned wire and is movable vertically as well as horizontally with respect thereto, the arrangement being such that the loop is suspended from the first mentioned wire when in its lowermost position and provides a support for the rods or bars comprising the ceiling material which is capable of being adjusted in any desired position.
A further object of the invention is to provide such a device which comprises, in combination with a piece of bent wire and a wire loop as above described, a cylinder having a removable cover and preferably formed of soft plastic material capable of being cut with a knife, the cylinder and its cover, in their applied positions, forming a mold for the cavity formed in the under side of the concrete structure and also as a container which encloses the wire loop and the intermediate portion of the first mentioned wire and is capable of maintaining them in predetermined position relative to each other and with respect to the concrete structure so that the device may be conveniently handled as a single unit, and optionally, a nail positioned axially with respect to the cylinder and extending through the end of the cylinder and its cover, for use in securing the device to a form preparatory to molding the concrete structure around it.
The invention will be readily understood by referring to the following description and the accompanying drawing, in which:
Fig. 1 is a perspective view showing a device embodying the invention in inverted position;
' Fig. 1;
Patented Oct. 25, 1960 ice Fig. 3 is a perspective view showing a pair of such devices as applied to a form for a concrete structure preparatory to molding the concrete;
Fig. 4 is a perspective view showing the concrete structure, with the devices embedded therein, before removing a the form;
{for engagement with the bars or rods supporting the ceiling;.and
Fig. 7 is a fragmentary, sectional, elevational vlew,
taken on a median line, of the device as shown in Fig. 6.
Referring to Figs. 1 and2 of the drawing, the device of the invention includes a piece of bent wire 1 having a straight middle portion 2, a pair of intermediate portions 3 which are bent substantially at right angles to the middle portion 2, and a pair of end portions 4 which are bent obliquely outwardly from the intermediate portions 3, the several portions 2, 3 and 4 lying in a common plane.
A wire loop 5 loosely surrounds the middle portion 2 of the wire 1 and a length of suspension wire 5' can be attached thereto, as shown in Fig. 6. The wire loop 5 and the middle portion 2 of the wire 1 are received bodily within a cylinder 6, which has a friction type cover 7. The cylinder 6 and the cover 7 preferably are made of soft plastic material capable of being cut with a knife, and have mutually aligned notches 8 and 9 formed in the adjacent edges thereof for engagement by the protruding intermediate portions 3 and end portions 4 of the wire 1. The cover 7 serves to seal ofI all concrete and grout from the cylinder 6 and its enclosed parts, and provides a compact and economical unit.
The length of the middle portion 2 of the wire 1 advantageously may be such that when the intermediate portions 3 and the end portions 4 are swung pivotally about the middle portion 2, the intermediate portions 3 bind against the adjacent surfaces of the cylinder 6, whereby the wire 1 is maintained in the position shown in Fig. l. The adjacent surfaces of the cylinder 6 may be notched for engagement with the intermediate portions 3 if desired, or alternatively, outwardly extending lugs 10 may be formed on the cylinder 6.
A nail 11, which is aligned axially with the cylinder 6, extends through the end of the cylinder 6 and its cover 7, the point of the nail 11 extending outwardly beyond the cover 7 and the head of the nail -11 being positioned adjacent the opposite end of the cylinder 6, which is closed.
Referring to Figs. 3 and 4 of the drawing, a pair of devices embodying the invention, as above described, are shown attached to the decking boards 12, which with the side board 13 form a concrete structure 15.
Fig. 5 shows the concrete structure 15 with the boards 12, 13 removed, leaving the cover 7 exposed and the nail 11 protruding downwardly below the concrete structure 15.
As shown in Figs. 6 and 7, the center portion of the cover 7 has been cut away, so that the wire loop 5 drops below the concrete structure 15 for engagement with the bars or rods (not shown) which support the ceiling. The point of the nail 11 has been cutoff.
The invention may be modified in various ways without departing from the spirit and scope thereof.
What is claimed is:
Ceiling suspension means, capable of being embedded in a concrete structure for use in suspending a ceiling therefrom, comprising a 'piece of bent wire having a straight first intermediate portion which, in its applied position, extends horizontally across a cylindrical cavity molded in the underside of anadjacent concretestruc- 'ture, and having a pair of second intermediate portions adjoining the first intermediate portion, on opposite sides thereof, and bent substantially at right angles thereto,
and a pair of end portions adjoining the respective second intermediate portions and bent obliquely outwardly therefrom, the several portions lying in a common plane and .the second intermediate portions and the end portions,
- intermediate portion of the first mentioned wire extending through it, the cylinder and the cover having mutually aligned notches in their adjacent edges through which the first intermediate portion of the first mentioned wire is passed, the second intermediate portions and the end portions of the first mention wire being positioned exteriorly of the cylinder, the length of the first intermediate portion of the first mentioned wire being such a 4 that when the second intermediate portions and the end portions thereof are swung pivotally about the first intermediate portion the second intermediate portions bind against the adjacent sides of the cylinder, abutments carried by the cylinder for yieldable engagement with the second intermediate portions of the first mentioned wire to restrain them against being swung pivotally about the first intermediate portion thereof, and a nail positioned near the center of the cylinder and extending throughthe end of the cylinder, and through its cover, for use in securing the device to a form preparatory to molding the concrete structure around it.
