A guy and strand hook for mounting on utility poles including a hub portion having an asymmetrical guy wire loop-retaining portion such as a rearwardly facing groove channel or seat, and a laterally extending lug overlying one end of the channel and a vertical lug overlying the other end of the channel.
What I claim is
1. A guy hook for mounting on a utility line pole or the like comprising a body adapted to be mounted vertically on a utility pole or the like, said body including a lower heel portion and an interconnected upper hub portion, means defining a bolt passage between said hub and heel portion adapted for the reception of a securing bolt, loop-retaining groove means defining a seat for the reception of the loop of a guy wire on the upper hub portion adjacent the pole, said seat extending transversely of said body, and asymmetrical means on said upper hub portion asymmetrically located as to vertical and horizontal portions of said loop-retaining groove means, for preventing disengagement of the loop of guy wire therefrom after the guy wire is in place.
2. The structure of claim 1 wherein the asymmetrical means includes a substantially horizontal lug at one side of the upper hub portion and a substantially vertically extending lug at the opposite side of said upper hub portion.
3. The structure of claim 1 wherein the seat includes a channel extending transversely of the body and has an arcuate lower surface and an oppositely arcuate upper surface.
4. The structure of claim 2 wherein said horizontal lug has an arcuate lower surface conforming to and comprising an extension of the arcuate upper surface of said channel.
5. The structure of claim 3 wherein said asymmetrical means includes a horizontal lug which extends out of the vertical plane of said hub.
6. The structure of claim 3 wherein said asymmetrical means includes a vertically extending lug which lies within the horizontal plane of said hub.
7. The structure of claim 3 wherein the radius of curvature of said lower arcuate surface is substantially less than the radius of curvature of said upper arcuate surface.
This invention relates to a guy hook for attachment to utility line poles or the like, and more particularly to the loop-retaining portion of such a hook.
The invention is an improvement on the hook described in applicant' s copending application Ser. No. 655,160, filed July 21, 1967, now abandoned.
Previously known guy hook structures have comprised an upper hub portion having a horizontal channel adapted for the reception of a securing bolt, and a lower heel portion including spikes for engaging the pole. The hub portion is usually offset from the pole, and contains a loop-receiving channel in its rear or pole-confronting face. It is necessary that the angle of inclination of the loop in the channel vary considerably from a sharp downward incline through horizontal, to an upward incline in accordance with the terrain and the location of the anchorage of the guy wire.
Various expedients have been employed to enhance the security of the retention of the guy wire loop in the channel, including crossheads, hooks and the like, but these are subject to slippage of the loop upon release of tension on the guy wire, and consequent disengagement of the loop from its associated hook or crosshead. The loop may be handmade in the strand itself or one of the several prefabricated strand-ending loop devices. For example, a U-shaped rod can be used as well as others.
One of the objects of the present invention is to provide means for securely retaining the loop in its associated channel or seat, and to protect the same against disengagement, while at the same time permitting pivotal movement of the loop about a horizontal as well as a vertical axis.
A further object of the invention is the provision of such a hook which is sturdy and durable in construction, reliable and efficient in operation, and relatively simple and inexpensive to manufacture and utilize.
In one aspect, the invention consists in a plate resisting overturning under sudden or accidental strains, and an offset hub having a groove or seat in the rear face thereof. An opening is provided for the reception of a securing bolt. The upper portion of the hub overlying the groove is provided at the top end with a laterally extending lug projecting beyond the horizontal plane of the hub, and at its other side with a horizontally extending lug lying substantially within the horizontal plane of the hub, the distance between the underside of horizontal lug and upper side of lug being substantially greater than diameter of strand and strand-holding device used with it.
Other features, objects and advantages of the invention will become apparent from the following description and drawings, which are merely exemplary.
In the drawings:
FIG. 1 is a front elevational view of a guy hook according to the present invention;
FIG. 2 is a side view partially in elevation and partially in section as seen from the right of FIG. 1; and
FIG. 3 is a top plan view.
Similar reference characters refer to similar parts throughout the several views of the drawing.
Referring now to the drawing in detail, the hook of the present invention is generally indicated at 10, and includes a heel 11 provided on its rear or pole-engaging face with a series of spikes 12. The heel portion bears against the pole and resists overturning under applied strains on the guy wire. In the form shown, an offset portion 13 extends between sidewalls 14 defining a channel 15 and terminating in a flat hub surface 16. A bore is defined by a tubular wall 17 which is adapted to receive a bolt for securing the hook to a pole or the like.
The rear portion of hub surface 16 which is offset from its associated pole is provided with a loop-receiving seat, groove or channel 18 which may be of a substantially semicircular cross section at its center, the lower wall of which falls away at its ends 19 to define a bottom wall of seat 18 which may be arcuate. The upper portion 20 may be arcuate, but with a materially greater radius of curvature. The top portion 21 of the hub is of substantial thickness, and portion 20 defines the top wall of groove or seat 18.
At one side of the top portion 21 a laterally projecting lug 22 having a lower surface 23 with a radius of curvature corresponding to that of the upper portion 20 extends laterally out of the substantially horizontal plane of hub surface 16 to prevent disengagement of a loop inserted in groove or seat 18, in the event of slack occurring in the guy wire or the like to which the loop is attached.
The other side of top portion 21 carries a substantially vertically extending lug 25 having a substantially flat outer surface 26 aligned with the sidewall of hub surface 16, to preclude, upon the occurrence of slack in the guy wire and subsequent twisting thereof, any lateral slippage of the loop. In assembling the strand loop onto the hook, it is turned parallel to the ground and at right angles to the through bolt, dropped over the loop-retaining means into the seat, and then turned to a position substantially parallel to the through bolt.
The combination of vertical and horizontal lugs which present an asymmetrical configuration serves to retain the loop securely against a variety of conditions, and results in a material saving in time and effort in connecting guy wires and the like to utility poles.
Similarly, the arrangement of the upper and lower arcuate walls of channel 18, if used, permits vertical pivoting of the loop to accommodate a wide variety of angles of inclination of the guy wire, both above and below the horizontal.
Obviously, the hook may be made in any desired size, or of any suitable material according to the purpose for which it is to be employed.
It is to be understood that changes in various details of construction and arrangements of parts can be made without departing from the spirit of the invention.
