1 claim.
This invention relates to an anchoring plug adapted to be embedded in various types of walls for supporting articles.
An object of the invention is the provision oi a plug stamped from two pieces of metal to form a sheath for the reception of a hre core, portions of the sheath having a series of key hole slots through which portions of the nbre core are forced when a wood screw in driven into the core for attaching a support to a wall, a pocket having been drilled previoinsly into the wall for the reception of the sheath.
A further object of the invention is the provision of a plug having the body thereof stamped from a single piece of metal to form a bottom and a pair of curved side walls rising integrally from the bottom thereof with key hole slots arranged transversely in said walls, portions of a core of brous materials being forced through said slots while expanding the side walls when a screw is driven into the core, the outer free ends of the side walls being connected together in spaced relation by a flanged cap having a central perforation through which the screw is driven for supporting a bracket or hook, the metal plug being received within a pocket drilled into a wall of a building. The screw may secure an article directly to the wall.
The invention is best understood from a consideration of the following detailed description in connection with the accompanying drawings, nevertheless, it is to be borne in mind that the invention is not conned to the disclosure but is susceptible of such changes and modications as shall deiine no material departure from the salient features of the invention as expressed in the appended claim.
In the drawings:
Figure l is a longitudinal vertical section of my anchoring plug shown in position ina pocket formed in the plaster of a wall,
Figure 2 is a longitudinal side view of the plug in an inoperative position,
Figure 3 is a transverse vertical section taken along the line 3 3 of Figure 2,
Figure 4 is a plan view of a metal blank from which a sheath of the plug is manufactured, and
Figure 5 is an enlarged longitudinal side view of a core formed of iibrous materials which is adapted to be inserted into the metal sheath.
Referring more particularly to the drawings I l) designates a section of a wall of a building. The wall may be formed of plaster of the type commonly employed for the purpose or the walls may be constructed of concrete or any well known 2 material. A pocket Il is drilled into the wall to a predetermined depth to provide an inner closed end i2 which will act as a barrier to ants or other insects.y
A metal sheath I5. is pressed into shape from a blank It illustrated in Figure 4. This blank consists principally of a central member I I from which extend flat metal strips I3 having the same width as the diameter of said central member. Hor-fever, during the stamping process, the strips i8 are pressed into the form of transversely curved side walls 2B of the sheath while the said walls are bent upwardly along the dotted lines 2 l. The member il forms the bottom wall of the sheath. Openings 22 which are modiiied forms of key-hole slots are ont through the metal strips I8. These openings include a circular passage 25 and diametrically disposed slots 26 projecting from the circular passage. During manufacture, the bottom is stamped to form a recessed base for the ber.
A cap 3B is circular and has an annular inturned ange 3| pinched onto the out-turned anges 32 on the outer free ends of the transversely curved side walls 20 of the sheath I5. The center of the cap is indented as shown at 35 and is provided with a passage 35 to receive a wood screw 3l. A length of brous material 38 (Fig. 5) forming a core or ller is placed in the sheath I5. A bracket, hook or other attaching means 4I) is secured to the plug by the head of the Screw. It must be borne in mind that many articles may be secured by the head of the screw 31 directly to the plug without the use of brackets or hooks.
The filler or core 38 is composed of three or more strands of brous materials, such as paper. Each strand consists of a thin narrow strip of paper which is rolled or twisted. The strands are then coiled as shown.
The pocket II (Fig. 1) is drilled into the wall which may be formed not only of plaster or cement but may be formed of plaster board or tile. As shown, the pocket terminates short of the rear face of said wall. The complete unit shown in Figure 2 is pressed into .the pocket by the thumb of the operator. The filler 38 housed within the sheath I5 is compressed in the inner end thereof by hammering the screw I1 into the nller for not only compressing said nller in the inner end of the sheath but for causing the iiller to expand its side walls of the sheath against the walls of the pocket. The sheath is formed of aluminum so that it will expand readily. The screw is withdrawn.
At this time, the inturned ange 3| on the cap 3% is in flat Contact With the front face of the wall l0. An opening in the bracket im, hook, or article which is adapted to be attached to the wall is alined with the opening 3l in the cap 3Q and the screw is inserted through said alined openings. A screw driver is employed for forcing the screw into the compacted ller 38. The modied form of key-hole slots 22 permits the fibrous materials to come into frictiona-l Contact with walls of the pocket Il while bending or stretching to some extent the transversely curved walls 2U of the sheath l5 so that said Walls will be expanded more readily against the walls of the pocket H. While the metal from which the blank I6 and cap 3|! are stamped is preferably aluminum, or some other soft or malleable metals, copper or brass may he employed.
When it is desired toremove the plug from the pocket, the screw 3'! is withdrawn and the cap 3i! is removed by any suitable instrument. screw is returned and screwed into the ller or iibrous core 38. A claw hammer or pliers are employed in pulling out the screw and core. The pliers will be used to withdraw the sheath i5.
It will be noted that the inner end of the sheath is expanded against the inner portions of the walls of the pocket. In this manner, there is no danger of cracking or chipping the outer surface of the Wall lll. This is particularly true when the pocket has been drilled into a tile or other l fragile or brittle material which may chip Where the pressure is exerted near the surface thereof. The plugs as will be appreciated may be used a number of times.
What I claim:
An expansion plug for a pocket in a Wall comprising a sheath formed from an elongated blank The of soft metal and including a pair of transversely curved side walls connected together at the inner ends thereof by a bottom portion and having radially outwardly directed ianges at their outer ends, a fibrous filler in the inner end of the sheath, said iiller comprising several strands of fibrous material, the strands being twisted together to form a solid unit, a disc having an annular inwardly directed ange at its outer odge and an aperture at its center, said ange of said disc engaging said outwardly directed flanges on the outer ends of said side walls and serving as a cap member therefor, and a screw inserted through said aperture and threaded into the filler to expand the iiller and thereby expand the side walls of the sheath against the walls of the pocket, the side walls of the sheath being provided with a plurality of key hole slots to acilitate the expansion of said side walls and to allow portions of said filler to frictionally engage the wai-ls of the pocket.
