ABSTRACT:
FIELD OF THE INVENTION
This invention relates generally to a bracket for mounting an enclosure to a supporting structure, and in particular to a mounting bracket kit for removably mounting an enclosure to a post.
BACKGROUND OF THE INVENTION
It is commonly necessary for linemen repairing or installing electrical power lines, telephone lines, and associated equipment to use instruments or tools which are conveniently housed in an enclosure which can be mounted to the utility pole at the work site. Preferably such an enclosure should be a weather tight box capable of being quickly and securely attached to, and removed from, a pole, such as a wooden or concrete utility pole, or a metal lamp pole, under adverse weather conditions. Frequently the enclosure, such as a tool box or an instrument box, is rather heavy and the bracket for mounting the enclosure to a pole must be strong and dependable. Such mounting brackets may need to be used repeatedly with one or more types of enclosures.
Previously such attachments were made with rope or wire or other improvised solutions dictated by the particular installation and frequently such devices were not entirely satisfactory. Such ad hoc solutions can be time consuming and unsafe. Such devices for mounting the enclosure are not always dependable or reusable and could possibly defeat the weather tightness of the enclosure.
U.S. Pat. No. 4,827,504 shows a mounting plate with straps passing through the plate for attaching a utility box to a pole. The utility box is connected to the plate with bolts passing through mounting ears on the box that engage threaded openings in the plate. Mounting and removing the box requires a lineman to use a tool for screwing and unscrewing the mounting bolts. In some locations, especially under adverse weather conditions, installing the bolts and manipulating the tool could be difficult and hazardous.
Although, various other devices for mounting objects, such as sporting equipment, lamps, shelves, ladders and the like to a support are known, there remains a need for a dependable, reusable enclosure mounting bracket, which is especially suitable for quick installation and removal, and secure mounting of an enclosure to a supporting base, which does not require the use of tools and which does not threaten the integrity of the enclosure.
SUMMARY OF THE INVENTION
Briefly stated the invention is for an enclosure mounting bracket kit containing at least one mounting bracket with an adjustable strap for attaching an enclosure to a post, such as a utility pole or a beam. The enclosure, such as an instrument box or tool box, includes a flange external to the enclosure which is provided with mounting holes for attaching to one or more mounting brackets.
The mounting bracket of the invention includes an elongated horizontal rigid bar having front and rear side surfaces and first and second ends; first and second elongated studs protruding from the front side surface adjacent the first and second ends respectively for penetrating the mounting holes of the flange; at least one through-hole in each of the first and second studs transverse to a long axis of the stud so that when each of the first and second studs penetrates a mounting hole the through-hole penetrates the flange; first and second releasable pins for positioning in each through-hole and gripping each of the first and second studs respectively; a block attached to the rear side surface of the bar between the first and second studs, the block having a surface generally conforming to the outside surface of a post; and an adjustable strap attached to the rear surface for encompassing the post.
In a preferred embodiment of the invention, the mounting bracket has a ratchet tensioning device attached to the rear surface adjacent the first end for retaining one end of the strap and tightening the strap around the post; a holder attached to an opposite end of the strap; and a hold-down attached to the rear side surface adjacent the second end for restraining the holder when the strap is tightened.
In another embodiment of the invention, the enclosure mounting kit further includes a second mounting bracket which includes an elongated horizontal rigid bar having front and rear side surfaces and first and second ends; first and second elongated studs protruding from the front side surface adjacent the first and second ends respectively for penetrating the mounting holes of the flange; at least one through-hole in each of the first and second studs transverse to a long axis of the stud so that when each of the first and second studs penetrates a mounting hole the through-hole penetrates the flange; first and second releasable pins for positioning in each through-hole and gripping each of the first and second studs respectively; and a block attached the rear side surface of the rigid bar between the first and second studs, the block having a surface generally conforming to the outside surface of the post.
The enclosure is preferably attached to the post; (a) either with one mounting bracket with the strap and ratchet and one mounting bracket without the strap and ratchet or (b) with two mounting brackets, each having a strap and a ratchet.
The novel aspects of this invention are set forth with particularity in the appended claims. The invention itself, together with further objects and advantages thereof may be more fully comprehended by reference to the following detailed description of a presently preferred embodiment of the invention taken in conjunction with the accompanying drawings.
