Filed June 6, 1958, Ser. No. 740,447 1 Claim. c1. 85-24) This; invention pertains to I an anchor for bolts; r
A P ma y i. .,.o theinventionis th provisionof anchor means for bolts which anchor means areyinsertable into sockets formed in building members such as walls, floors, or the like.
The general purpose of anchors of. this type is: to-provide an expandable seat for a bolt. placed therein;so as to securely connect the bolt to the building member. These anchors are normally utilized where it is desired to secure a panel covering or the like to a building member which, because of the material of which the building member is constructed, does not provide a suitable vehicle for receipt of the bolt.
Another objective of the present invention is to form the bolt anchors constructed and assembled thereunder of a material of the character or type known as, and sold under the trademark Polypenco nylon, or an equivalent thereof. This material is a non-oxidizing plastic and therefore will not rust or otherwise discolor Walls or the like. Also, the bolts placed therein will not become bound to the anchor assembly by the corrosion thereof.
Forming the anchors of a material of the above mentioned class has been found to result in the following additional advantages: low'weight, high strength, and acid and alkali resistent.
Another object is the provision of bolt anchors which may be readily color-coded for visual identification of the various sizes thereof.
Another object is the provision of a bolt anchor wherein no special tools are required in accomplishing the installation thereof.
A further advantage resides in the fact that anchors constructed and assembled in accordance with the teachings of this invention may be removed from the building member in which they have been placed by a simple drilling process.
A still further object is the provision of a bolt anchor having a self-locking action inherent in the construction thereof. Also, the construction employed allows the provision of a reduced outer diameter of the assembly which, in turn, results in a lessened expense in the construction and installation thereof.
Another object resides in the provision of an anchor for bolts comprising a substantially hollow, frusto-conical main body portion, a substantially hollow cylindrical sleeve having a pair of opposed open ends, the truncated end of the main body portion being inserted into one of the open ends of the sleeve, a bolt threadedly connected within the main body portion, and means for preventing the rotational movement of the main body portion relative to the sleeve.
Among the further objects and advantages of the instant invention is the provision of an anchor for bolts of the class described supra, the anchor assembly being non-complex in construction and assembly, inexpensive to manufacture, and durable in use.

Figure 2 is an exploded perspective view ofthe anchor assemblyandbolt;
Figure 3 is a perspective view of the sleeve portion of the anchor assembly;
Figure .4 is an enlargedend elevational view. of. the anchor assembly and bolt; 1
Figure 5 is a detailcross-sectional view ofthe assembled device taken. substantially along the vertical plane of the line 55 of Figure 4, looking in the direction of the arrows; and Y Figure 6 is a side elevational view .of. the device in place in a socket formedin a building member, and showing a panel or the likebeing held flush against the. building-member.v
Referring to the drawing, general reference numeral 10 connotes the anchor assembly which is formed of a plastic material, such as, for example, that known as Polypenco nylon. The assembly 10 is seen to include a frusto-conical main body portion 12 having an inwardly threaded, cylindrical bore 14 extending longitudinally therethrough, the bore 14 being coaxial with the longitudinal axis of the main body portion. As best seen in Figures 2 and 5, the main body portion 12 has a pair of opposed open ends 16, 18 providing ingress and egress to the bore 14. The main body portion also is provided with a plurality of longitudinally extending, alternate lands 20 and grooves 22, for a purpose to be described more fully below.
The second major portion of the anchor assembly 10 is a substantially cylindrical hollow sleeve 24 having a pair of opposed open ends 26, 28. The sleeve 24 has a frusto-conical opening 30 formed therein and extending longitudinally and convergingly from the open end 28 to a juncture thereof with a coaxial bore 32 extending inwardly from the opposed open end 26, the aforementioned juncture being adjacent the open end 26. The sleeve 24 also is provided with a plurality of alternate lands, 34 and grooves 36 extending longitudinally the length of the opening 30. The sleeve 24 has longitudinal slots38 formed therein which extend inwardly from the end 28 in order that the sleeve 24 may be flared in a manner to be explained below.
In operation, a cylindrical socket 40 is former in a building member 42 to which it is desired to mount a panel 44 or the like, and the assembly 10 is placed therein. An opening 46 is formed in the panel 44 which is positioned over the socket 40 and a cylindrical bolt 48, having a head 50, is passed therethrough and threadedly connected to the threaded bore 14 of the main body portion 12.
With special reference to Figure 5, it is seen that when the end '16 of the main body portion 12 is inserted into the opening 30 of the sleeve 24, the alternate lands 20 engage in the grooves 36 and the other alternate lands 34 engage the groove 22, thus effectively eliminating any rotational movement of the main body portion 12 relative to the sleeve 24.
When the head 50 of the bolt 48 is pressed against one side of the panel 44 and the end 26 of the sleeve 24 is against the opposed side of the panel 44, further rotation of the bolt '48 causes the main body portion 12 to be drawn into the sleeve 24, and to flare the slotted end thereof in wedge fashion. Thus, the slotted end of the sleeve presses and frictionally engages against the sides of the socket 40 and efiects a secure connection of the panel 44 flush to the building member 42.
Having described and illustrated a single embodiment of this invention, it will be understood that the same is offered merely by way of example and that .this invention is to be limited only by the scope of the appended claim.
What is claimed is:
A bolt anchor for insertion in a bolt hole having a given diameter, said bolt anchor comprising a substantially frusto-conical body portion formed of nylon, plastic, resilient material and having a threaded bore formed therein and extending the full length thereof, said body portion including an enlarged base end and an opposing diminished end, said body portion tapering from the base end to the diminished end thereof, said body portion including a plurality of longitudinally extending, substantially triangular, exterior serrations thereon; an elongated, substantially cylindrical, hollow sleeve formed of said material, said sleeve including a pair of opposing open ends, .said sleeve having normally a given uniform diameter less than said given diameter of said bolt hole, said sleeve including an inner end portion having a plurality of circumferentially spaced, longitudinally extending slots formed therein, said inner end portion including a plurality of longitudinally extending, substantially triangular, interior serrations therein; the diminished end of the body portion being adapted for insertion into the inner end portion of the sleeve, the serrations of the body portion inter-engaging with the serrations of the inner end portion of the sleeve to prevent relative rotation therebetween, the insertion of the body portion into the sleeve serving to flare the inner end portion outwardly to at least the diameter of the hole thereby to frictionally engage the same therein; and an elongated, threaded bolt adapted for insertion through the sleeve for engagement with the threaded bore of the body portion thereby to draw the body portion into the sleeve to further flare the inner end portion thereof.
