Application October 9, 1953, Serial No. 385,173
1 Claim. (Cl. 248-29) This invention relates to improvements in anchor bolt structure for mounting such as pictures, wall brackets, and any other mountings, on plaster lath and like walls, and the primary object of the invention is to provide a more practical, reliable, and eflicient device of this kind which can be installed through a hole in a wall with greater accuracy as to position, and without marring the exposed surface of the wall, and which will not ordinarily become loosened in the wall hole but can be easily tightened without marring the exposed surface of the wall.
Another important object of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration rather than limitation, a specific form of the invention is set forth in detail.
In the drawings:
Figure 1 is a fragmentary perspective view partly broken away, showing an installation in accordance with the invention;
Figure 2 is an enlarged fragmentary transverse vertical section taken on the line 2--2 of Figure 1;
Figure 3 is a view similar to Figure 1, showing the illustrated anchor bolt device installed for hanging a picture or the like;
Figure 4 is a View similar to Figure 3, showing the device in a preliminary stage of installation; and
Figure 5 is an exploded view of the said device.
Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the illustrated anchor bolt structure or device, which is generally designated 7, comprises an anchor bar 8, a headed sleeve 9, a positioning wire 10, a screw 11, and a wrench 12 which can also serve as mounting means for a picture or the like.
The anchor bar 8 is preferably a piece of half-round stock having a flat side 13 for engaging the rear side 14 of a wall panel 15 through which a hole 16 has been made, with the anchor bar 8 extending across the hole 16, the anchor bar 8 being substantially longer than the diameter of the hole 16, and provided with a central threaded hole 17 bevelled at its rearward end, as indicated at 17 The headed sleeve 9 comprises a tubular externally threaded part 18 preferably smaller in diameter than the wall hole 16, and perrnissibly somewhat shorter than the width of the wall panel 15, although the tube 18 can be longer. On one end of the tube 18 is fixed a concentric solid cylindrical head 19 of substantially the same diameter as the hole 16 and adapted to have a plug fit therein, as particularly well shown in Figure 2 of the drawings. The head 19 has a lateral annular flange 20 on its outer end which is arranged to engage the exposed surface 21 of the wall panel 15.
The flange 20 is provided in its peripheral edge with diametrically opposed rounded notches 22, 22 for a purpose hereinafter disclosed.
The positioning wire 10 comprises a length 23 of 2,765,134 Patented Oct. 2, 1956 flexible wire having fixed on one end thereof the disc stop or abutment 24 whose peripheral edge is bevelled on its outer or front side, as indicated at 25. The disc 24 is slightly larger in diameter than the threaded hole 17 of the anchor bar 8 and arranged so that the bevelled side 25 seats in the bevelled end 17 of the threaded hold 17 whereby the disc 24 has a positioning purchase upon the anchor bar 8, in a manner and for a purpose hereinafter explained.
The screw 11 has a threaded shank 26 and a rounded slotted head 27, the shank 26 being arranged .to be threaded into or through a central threaded bore 28 extending through the sleeve head 19. The screw 11 is adapted to be passed through an opening provided in an object to be mounted on the wall panel 15 or suspension means for such object can be instead hung over the screw behind its head 27.
The wrench 12 comprises an elongated rectangular body having a flat outer side 29 and an inner side 30 which has a flat central portion 31 and longitudinally vertically bevelled or tapered end portions 32, 32. The wrench is provided with a smooth central hole 33 therethrough in which the shank 26 of the screw 11 can freely turn, the hole 33 being smaller than the screw head 27, so that the screw head 27 can be tightened against the outer side 29 of the wrench 12 for holding the wrench 12 in an object supporting position, such as is exemplified in Figures 1 and 2 of the drawings. The wrench has on the intermediate portion 31 of its inner side 38, two longitudinally spaced and diametrically opposed pieces 34, 34 which fit the notches 22, 22 in the flange 20 on the head 19 of the sleeve 9, for a purpose hereinafter explained, as well as for preventing rotary shifting of the wrench 12 when installed as shown in Figures 1 and 2. The pins 34, 34 are shorter than the thickness of the head flange 20 so that the free ends of the pins will not reach behind the head flange 20 and mar the wall panel surface 21.
The above described device is installed as follows:
The anchor bar 8, with the wire length 23 extending through its threaded hole 17 and the disc 24 engaged with the rear end of the hole 17, is pushed rearwardly through the wall panel hole 16 until the anchor bar 8 goes behind the wall panel 15. Thereupon the wire length 23 is pulled forwardly so as to seat the disc 24 in the anchor bar hole 17, position the anchor bar 3 across the wall hole 16 at the rear side of the wall panel 15, and the wire length is held to maintain this position of the anchor bar 8.
The headed sleeve 9 is then passed over the wire length 23 into the wall hole 16 and engaged with the anchor bar hole 17 and threaded therein by rotating the head by means of the wrench 12, the pins 34, 34 being engaged in the head flange notches 22, 22, until the head flange 20 is tightened against the exposed surface of the wall panel 15. At this point the wire 10 is pushed through the sleeve 9 and dropped behind the wall panel 15 by pushing the wire rearwardly through the bore of the sleeve 9.
The screw 11 is then threaded into the threaded bore 23 of the sleeve head 19 as far as necessary, either to provide a nail for hanging an object or to clamp an object between the screw head 27 and the outer end of the sleeve head 19.
Optionally, the wrench 12 can be clamped in place at the outer end of the sleeve head 19 by passing the screw 11 through the hole 33 of the wrench 12 and tightening the screw head 27 thereagainst.
What is claimed is:
In an anchor bolt device, an anchor bar adapted to engage the rear side of a wall panel and to extend across a hole provided through the wall panel, said anchor bar having a central threaded hole, a headed sleeve comprising a head fitting the wall hole and a reduced diameter externally threaded tube extending rearwardly from said head through the wall hole, said tube having a rear end threaded in the hole of the anchor bar, said head having 'a lateral flange engaging the front of the wall, said head flange having circumferentially spaced notches, an article supporting member cernprising an elongated body having a central hole therethrough, and spaced pinson said body engaging the head flange notches for rotating the headed sleeve fer threading said tube into the threaded hole in the anchor bar, the bore in the sleeve head being threaded, and a screw having a shank extending through the hole of said member and threaded in the threaded bore of the head and a head bearing against the outer side of said member.
