Description:

BACKGROUND OF THE INVENTION

This invention relates apparatus for adjusting the tension in a cable that is being used in supporting other structure, for example bay and bow windows of a building.

At the present, there are devices that are mountable to a building for mounting one end portions of cables while the opposite end portions of the cables are attached to a load, for example bay and bow windows, to aid in supporting such a load in a desired condition.

In order to provide novel devices that are relatively inexpensive and usable to adjust the tension in a cable or a rope that is at least partially supporting a load, this invention has been made.

SUMMARY OF THE INVENTION

The cable bracket mechanism includes an elongated bracket having a flange at one end that generally extends at right angles to the main body of the bracket for having one end portion of a cable stud connected thereto and a hook portion at the opposite end of the main body for being connected through suitable mechanism to a load being supported. The other end of the cable is attached to a building by suitable means, for example by a cable clamp or cleat. The bracket and stud permit adjusting the tension in the cable.

An object of this invention is to provide new and novel means for adjusting the tension in a cable or rope that is utilized in supporting a load from a supporting structure. A further object of this invention is to provide new and novel cable bracket apparatus that is usable for at least partially supporting structure such as a bay or bow window and permitting easily making an adjustment to obtain a desired elevation and/or leveling of such windows. A still further object of the invention is to provide a new and novel bracket that is usable in conjunction with a cable for supporting structure such as a bay or bow window and facilitating the adjustment of tension in the cable.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and in particular to FIG. 1, there is diagrammatically shown a cable clamp or cleat 11 mounted by nails or screws 12 to an exterior wall 13 or to an overhanging part (not shown) of a building, for example a house, above a bow or a bay window 14 which is generally shown in outline other than for the dotted line showing of a mullion 14A, a seat board 14B, and a top board 14C of the window. The mullions 14A are remote from the house exterior wall. Rods and/or cables 18 are extended downwardly through the mullions while suitable fasteners 17, for example washers and nuts are mounted to the lower ends of the rods in supporting relationship to the seat boards.

For connecting the upper end of the rods to the clamps or cleats 11, there is provided the cable bracket mechanism, generally designated 20, of this invention. The cable bracket mechanism includes an elongated flexible cable 22 which may be made of twisted metal strands and has one end portion secured to the exterior wall by a cable clamp or cleat 11 while the opposite end of the cable is extended into an axial bore (not shown) in the non-threaded end portion 20 of an axially elongated metal stud, generally designated 23. The cable is suitably joined to the stud, for example by a swaging operation.

The end portion of the stud opposite the cable is threaded at diametrically opposed threaded parts 24 while diametrically opposed flats 25 extend between the diametric threaded parts. The threaded end portion of the stud is extended through an oblong cable stud aperture 27 that extends longitudinally through the flange 28 of a longitudinally elongated bracket B, the aperture being sufficiently spaced from the main body 29 whereby a nut 35 may be threaded thereon. Advantageously, the aperture 27 is of a size and shape to permit the stud threaded portion being moved through the aperture along the axial length thereof while preventing the stud being rotated relative to the flange.

The bracket B has the main body 29 that for the majority of its length is rectangular, has transversely spaced longitudinal edges 29E and is of a longitudinal length many times greater than its transverse width which in turn is many times greater than its thickness. The flange is joined to one longitudinal end portion of the bracket main body 29 to extend at generally right angles thereto. The longitudinally opposite end portion of the main body becomes progressively more narrow along bracket end part 29A in a direction away from the flange. The main body has a generally planar surface 29C extending transversely between the main body longitudinal edges 29E from at least the narrow end part 29A to the flange and an opposite planar surface 29B that extends longitudinally from the narrow end part to the main body end portion to which the flange is joined. The narrow end part of the main body is integrally joined to the hook portion 30 which is reversely curved relative to the narrow end part. The hook portion opens in a direction generally toward an extension of the flange on the opposite side of the main body from which the flange extends. Thus, the hook portion is curved such that after extending longitudinally away from the main body, it is curved to extend further away from the plane of the planar surfaces of the main body in a direction opposite the direction that the flange extends away from the main body planar surfaces and extends at least somewhat longitudinally toward the flange. Accordingly, at least part of one of the narrow end part 29A and the hook portion are in overlapping relationship to the free terminal transverse edge 30A of the hook portion which is spaced from the main body surface 29B.

The hook portion is extendable through the opening 31A in the leg 30B of the eye bracket 31. The eye bracket leg 31B is joined to eye bracket leg 31C which extends at an obtuse angle to leg 31B, for example about 160 to 105 degrees. The leg 31C is mounted to the window board 14C by having the rod extended though a rod aperture (not shown) in leg 31C and is removably retained in a mounted relationship thereto by fasteners such as a nut 33 threaded on the top end of the rod 18 to retain a washer 32 in abutting relationship to the member 14C of the window. In using the apparatus of this invention, the eye bracket is attached to the window top board with the rod 18 extended through the rod aperture and the washer 32 and nut 33 mounted on the rod, the bracket hook is portion extended through the eye bracket aperture 31A, the threaded end portion of the stud is extended through the flange aperture and a nut 35 is threaded on the threaded end portion of the stud to be intermediate the flange and the bracket hook portion with there being a lock washer 37 between the flange and nut 35 and the free end portion of the cable attached to the wall 13 by the clamp and cleat 11 to retain the cable in a taut condition. Thereafter, the nut 35 is further threaded on the stud to increase the tension in the cable, or unthreaded an appropriate amount to decrease the tension in the cable, depending what is required to support the window in the desired condition. With more than one cable bracket mechanism being utilized, appropriate adjustments are made in each of the cable bracket mechanism used until the window is supported in a level condition at the elevation as desired.

Advantageously, the bracket B is formed integrally as a single unitary unit. In place of the eye brackets being mounted to the rods 18, the eye brackets may be mounted to the window remote from the wall 13 by screws (not shown) extended through apertures in the eye bracket leg 31C. Additionally, instead of the narrow end part extending at an angle relative to the main body such as shown in FIG. 3, it may be at least in part a planar continuation of the rectangular portion of the main body, or as another alternative, the hook portion may be joined to the rectangular, planar main body portion and progressively curve to initially extend longitudinally away from the flange in a direction opposite that from which the flange extends away from the main body and thence in a direction toward an extension of the flange away from the main body on the opposite side of the main body from which the flange extends while at the same time being of a much narrower dimension than the transverse dimension of the main body rectangular portion. Also, in place of the threaded portion of the stud having flats and the bracket flange aperture being of a shape such as shown in FIG. 4, the second embodiment of the stud and bracket of the cable bracket mechanism may be the same as that of FIGS. 1-4 other than that the threaded portion 40A of the stud 40 is circular whereby the thread extends continuously helically around the stud, and the aperture 41 of the bracket flange 42 is circular and of a slightly larger diameter than the maximum diameter of the threaded portion.
