EXPANSIBLE HANGER BARS FOR SUPPORTING ELECTRIC OUTLET BOXES Filed Feb. 9, 1953 IN VEN TOR.
nited EXPANSIBLE HANGER BARS FDR SUPPORTING ELECTRIC OUTLET BOXES The present invention relates to expansible hanger bars for supporting electric outlet boxes, and has for its main object the provision of a hanger bar embodying a tubular portion, preferably of a square formation on transverse cross section, and a threaded rod receivable within said tubular portion, and whereby the two may adjustably expand when one is rotatably shifted with relation to the other.
Another object of the present invention is the provision of a hanger bar of the character indicated wherein the tubular portion and the threaded rod at their free ends may be provided with a set of prongs capable of being driven into a pair of adjacent wooden joists in ceilings or walls.
Another object of the present invention is the provision of a hanger bar of the character indicated wherein the tubular portion thereof may be made of an oblong strip of metallic material, which when suitably bent may have a pair of complementary sections, each provided with a threaded recess, the two recesses forming a threaded bore when the section are in their contacting operative position for the purpose of receiving the threaded rod.
With the above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.
In the drawing forming a part of this application, and in which like designating characters refer to corresponding parts throughout the several views;
Fig. 1 illustrates a side elevational view of the hanger bar made in accordance with the present invention, engaged by its ends with a pair of spaced joists, and having an electric outlet box suspended thereon in an operative position;
Fig. 2 is a transverse cross sectional view, on line 22 of Fig. 1, illustrating the manner of afiixing an electric outlet box to the hanger bar;
Fig. 3 is a longitudinal cross sectional view through the outer end of the tubular portion of the hanger bar with prong-supporting plate swivelly supported upon the end of said tubular portion of the hanger bar;
Fig. 4 is a side elevational View of the tubular portion of the hanger bar of another construction;
Fig. 5 is a transverse cross sectional view on line 55 of Fig. 4; and
Fig. 6 is an end elevational view of the tubular portion of the hanger bar illustrated in Fig. 4.
Referring in detail to the present drawing there is shown a hanger bar which includes tubular portion 10 provided with a longitudinal bore 11. The body portion of said tubular portion 10 adjacent said bore 11 and within the inner end thereof is threaded as at 12 for receiving therewithin in a threaded relation threaded rod 13.
The free end of said threaded rod 13 carries in a rigid relation plate 14 from which a plurality of prongs 15 project in an outward direction. The opposite end of tubular portion 10 of the hanger bar is provided with a reduced lug 16, round in a transverse cross section, which passes through plate 17 which plate by its outer face supports a plurality of prongs 18. The outer end of said lug 16 is hammered down to define rivet head 19. The diameter of said lug 16 is smaller than the diameter of the bore in plate 17 through which said lug 16 is passed, permitting free rotary movement of said lug 16 within said plate 17. By virtue of this arrangement plate 17 is freely swivelled upon the outer end of said tubular portion 10 of the hanger bar.
From the hereinabove description it will be seen that when the hanger bar is placed between and transversely of a pair of spaced joists 20, and prongs 15 carried by the threaded rod 13 are pressed against the adjacent surface of the adjacent joist 29 said latter prongs will be driven into said joist for maintaining said threaded rod 13 in a stationary relation with respect to said joists 20. When a rotary movement to the tubular portion 10 of the hanger bar is applied, first by hand, and when prongs 18 have been engaged with the adjacent opposite joist 20, with a wrench, and a rotary movement to said tubular portion 10 is continued to be applied, said tubular portion 10 will shift upon threaded rod 13. By virtue of this action the two parts of the hanger bar, that is tubular portion 10 and threaded rod 13 will expand, with the result that prongs 15 carried by threaded rod 13 and prongs 18 carried by tubular portion 10 of the hanger bar will be fully driven into the adjacent and respective joists 20, as is seen in Fig. 1, for rigidly supporting the hanger bar between the pair of adjacent joists and in a firm engagement therewith through prongs 15 and 18.
It is noted that during the rotary shifting movement of tubular portion 10 of the hanger bar plate 17 and prongs 18 are stationary, that is they do not rotate with said tubular portion 10 by virtue of the swivelled connection of said tubular portion 10 with said plate 17 through said lug 16, as was hereinabove described.
In an encompassing and longitudinally sliding relation with said tubular portion 10 of the hanger bar is collar 21, which is square on transverse cross section, and which upon each of its four faces is provided with a threaded bore 22.
Electric outlet box 23 has upon its peripheral side a plurality of indents 24, which when forced out of the body portion of said peripheral side will define openings through which electric wires may be extended. Externally threaded stud 25 by its outwardly flanged end 26 is extended through a central opening made in the end wall 27 of box 23. Winged locknut 28 threadedly engages said stud 25 and bears by its free ends against the inner face of said end wall 27. The opposite end of said stud 25 has a countersunk bore for receiving the head of a flathead screw 29. Said screw 29 is adapted to engage anyone of said threaded bores 22 and when so engaged said stud 25 is firmly clamped to the adjacent face of said collar 21, said screw by its threaded end bearing against the face of said tubular portion 10 of the hanger bar.
By virtue of the arrangement described it will be noted that before applying outlet box 2.3 to collar 21 the collar is adjusted upon said tubular portion 10 of the hanger bar, and when said collar 21 has been brought to a desired point upon said tubular portion 10 of the hanger bar the outlet box 23 is then rigidly engaged with said collar through the medium of said screw 29.
The modified form of the invention illustrated in Fig. 4 contemplates making the tubular portion of the hanger bar out of an oblong strip of metallic material, which when properly formed will define connecting end member 30 from which lug 31 projects. Each of the sides 32 adjacent their opposite ends is provided with solid block 33. Adjacent the inner face of each of said blocks 33 a complementary threaded groove 34- is made. The two grooves 34 when said blocks are brought in a mutual contactual relation define threaded bore 35 for receiving therewithin in a threaded adjustable relation threaded rod 13. In order that the ends of said sides 32 having said blocks 33 would not spread away from each other but would be maintained in a rigid mutual relation a plurality of metallic bands 36 are passed around said sides 32 and at their portions wherein said blocks 33 are located. Each of said sides is provided with a pair of inwardly extending Wings 37. A pair of said wings 37 along the opposed edges of said sides 32 define a solid wall section 38. A pair of opposed walls 38 in conjunction with the adjacent portions of sides 32 define a tubular section for adjusting thereon in a longitudinal relation collar 21. That tubular section is capable of supporting outlet box 23 with screw 29 engaging thereat either one of said sides 32 or one of said wall sections 38. Lug 31 receives plate 17 carrying prongs 18, and when the free end of said lug 31 is thereupon hammered down the same will define rivet head such as head 19 for preventing the disengagement from lug 31 the prongcarrying plate such as plate 17. Of course plate such as plate 17 should be swivelled upon lug 31 for the purposes already mentioned.
From the hereinabove description it will be seen that tubular portion 10 or sides 32 of the hanger bar are capable of rotation by means of ordinary wrench. Collar 21 is preferably provided with a threaded bore on each of its four sides in order that that bore 22 may receive screw 29 for supporting box 23, which has been brought.
to the lowermost position by rotatably turning tubular portion 10 or sides 32 of the hanger bar.
It is further observed that the conventional hanger bars now in general use are afiixed to the joists by passing nails or screws through the ends of the hanger bar and driving the screws or nails into the joists. This operation necessarily requires complete exposure of the joists and this in turn requires a large opening to be made either in the ceiling or in the wall. On the other hand, the present invention requires a comparatively small opening in the ceiling in order to insert therethrough the hanger bar including the tubular portion 10 or sides 32, as the case may be, with the cooperating threaded rod 13, with collar 21 already in an operative position. When said parts have been inserted through the opening made, with prongs 15 pressed against one of the joists 20, all that is required to drive said prongs 15 as well as prongs 18 into the respective joists is the manipulation of the tubular portion 10 or sides 32 by means of a wrench, until both of said prongs 15 and 18 have been fully driven into their respective joists. Thereupon collar 21, already on the tubular portion 10 or sides 32 is shifted for adjusting said collar within the opening made in the ceiling or the wall, and thereupon affixing the outlet box 23 to said collar by means of screw 29 as was already described.
It is also noted that collar 21 is inserted upon sides 32 of the modified form of invention shown in Fig. 4 before prong-carrying plate has been mounted upon lug 31 and before said lug 31 has been hammered down, or if preferred said collar 21 may be inserted from the opposite end of that portion of the hanger bar before bends 32 have been applied.
Of course, screw 29 driven through one of said bores 22 will strongly bear against the adjacent face of the tubular portion 10 of the hanger bar or one of the sides 32 or walls 38, thereby maintaining said collar 21 in a strong engagement with the hanger bar, preventing the same from shifting in either direction with relation thereto.
It is further noted that prongs 15 and 18 fully driven into the joists will render the hanger bar capable of supporting electric fixtures of considerable Weight, more so than the conventional hanger bars.
The present hanger bar is most particularly adapted for use in connection with the ceilings or walls already made and plastered, particularly in cases Where the location of additional electric outlets are required after the dwelling has been built and its ceilings and walls have been plastered.
Affixable to the free lower end of said stud 25 in a threaded relation is a hollow rod upon which any type of electric fixture may be suspended.
While there is described herein preferred embodiments of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
