7 Claims. (Cl. 248-205) This invention relates to an adjustable anchor particularly intended for use with metal door bucks.
Quite frequently it is desirable to support outlet boxes, thermostats, signs, telephone outlets, tubing, and other devices from a metal door buck. Anchors for this purpose have been proposed in the past as will be exemplified by the disclosure of the patent to Habel, No. 2,045,594, issued in 1936. The present invention constitutes an improvement over prior art devices of these types from the standpoints of simplicity, cost, ease of installation, rigidity and degree of adjustability.
It is among the objects of the present invention to provide an adjustable anchor comprising a base member having a web portion terminating at one end in a flange, and a bracket member having a web portion terminating at its ends in a flange and an arm respectively, one of the web portions containing a slot and the other an opening for the reception of fastening means, each of the web portions containing a threaded opening therethrough adjacent its flange for the reception of a screw, the fastening means securing the web portions in superimposed relationship, the arm and flanges extending in the same general direction with the arm disposed between the flanges. One of the web portions preferably carries guide elements for restraining relative transverse movement of the other, for which purpose flanges along the side edges of such webportion are eminently satisfactory. The flanges are disposed substantially at right angles to the web portions and are substantially equal in length. The bracket member is preferably of substantially J-shape in elevation and except for the fastening means and screws, there are only two parts involved.
A more complete understanding of the invention will follow a description of the accompanying drawing wherein:
Fig. l is a side elevation of an adjustable anchor according to the present invention, shown in its assembled position with respect to a door buck depicted in section;
Fig. 2 is an end view of the anchor only; and
Fig. 3 is an exploded view of the anchor.
A typical metal door buck is depicted in section in Fig. 1 as provided with a stop 12, parallel flanges 14 and opposed flanges 16. The adjustable anchor 18 constituting the subject matter of the present invention includes a base member 20 and a bracket member 22 having web portions 24 and 26 respectively. The web portion 24 of the base member 20 terminates at one end in a flange 25 and along its side edges carries integral flanges 28 forming a channel for the reception of the web portion 26 carried by the bracket member 22.
The web portion 24 of the base member 20 is provided with a pair of threaded openings 30, either of which may receive a screw 32 introduced through a slot 34 provided in the web portion 26 of the bracket member 22. The web portion 26 terminates at one end in a flange 36 similar to the flange 25 of the base memher, and at its other end in an arm 38 containing any May desired number of openings 40, depicted as slots, to receive fastening means for the attachment of outlet boxes, plumbing accessories, or any other type of accessory or fixture desired. The web portion 24 of the base member 29 is provided with a threaded opening 42 adjacent its flange 25 forthe reception of a screw 44. Similarly, the web portion 26 of the bracket member 22 is provided with a threaded opening 46 adjacent its flange 36 for the reception of a screw 48. The end of the web portion 24 remote from the flange 25 is shown in Fig. 2 as containing a notch 50 serving as a seat for the screw 48 when the parts are relatively retracted.
The parts of the adjustable anchor are assembled by introducing the web portion 26 of the bracket member 22 between the flanges 28 of the base member 20 so that the slot 34 will register with either of the threaded openings 30 whereupon the screw 32 will be introduced through the slot into the threaded opening. With these parts relatively retracted, the anchorwill be introduced between the flanges 16 of the door buck 10 until the two parts of the anchor can be extended as far as possible so that its flanges 25 and 36 will engage the flanges 14 of the door buck. Under these conditions, the screw 32 will be tightened to maintain the parts of the anchor in rigid assembled relationship. Then the screws 44 and 48 will be advanced until the ends of the flanges 25 and 36 engage the inturned flanges 16 of the door buck, whereupon the installation is complete. At this time the device to be supported can be attached by suitable fastening means introduced through the slots or other openings 40 provided in the arm 38 of the bracket member.
By virtue of the provision of clamping screws 44 and 48 adjacent their respective flanges 25 and 36, a high degree of rigidity is assured to the anchor itself as well as to the device or devices to be supported therefrom.
In order to adapt the anchor to walls of various thicknesses, the arm 38 of the bracket member 22 can be bent to provide such diflerent degrees of offset as may be desired.
Whereas only one specific form of the invention has been described with reference to the accompanying drawing, the invention should not be restricted thereto beyond the scope of the appended claims.
1. An adjustable anchor comprising a base member having a web portion terminating as an entirety at one end in a flange, and a bracket member having a web portion terminating as an entirety at one end in a. flange and at its other end in an arm, one of said web portions containing a slot and the other an opening for the reception of fastening means, each of said web portions containing a threaded opening therethrough adjacent its flange for the reception of a screw, a screw received in each of said threaded openings and extending beyond said web portions, said fastening means securing said web portions in superimposed relationship, said arm and flanges extending in the same general direction with said arm disposed between said flanges.
2. An adjustable anchor as set forth in claim 1 wherein one of said web portions carries guide elements for restraining relative transverse movement of the other.
3. An adjustable anchor as set forth in claim 1 wherein one of said web portions is provided with flanges along.
its side edges for restraining relative transverse movement of the other.
4. An adjustable anchor as set forth in claim 1 wherein said flanges are disposed substantially at right angles to said web portions.
5. An adjustable anchor as set forth in claim 1 wherein said flanges are substantially equal in length.
6. An adjustable anchor as set forth in claim l where in said bracket member is substanllally J-shaped in elevation.
7. An adjustable anchor as set forth in claim 1 wherein the length of said arm exceeds that of each of said flanges.
