Abstract

ABSTRACT OF THE DISCLOSURE
Conventionally, resilient straps are provided with a hook at each end and are used as tie-down straps for various purposes. These normally do not have any means for adjustment so that a variety of sizes is required to suit certain circum-stances. The present device consists of a hook formed from spring steel wire or the like and having an angulated other end adapted to receive a flat resilient strap of elastomeric material, in an adjustable manner, and to clamp same at the desired posi-tion on the strap against slippage during extension and use of the strap. The angulated other end includes a cross bar extend-ing perpendicularly from said hook portion and a closed loop portion spaced from said cross bar defining a strap engaging open side space between said first cross bar and said closed loop.

Description

BACKGROUND OF THE INVENTION
The present invention relates to new and useful im-provements in hooks for tie-down straps associated with said hooks.

Normally these devices are known as BUNGEE cords and consist of substantially circular cross section elastic material either synthetic or natural with a hook permanently attached to each end, usually by a clamping or clinching method. This means that although the cords can be utilized as hold-down devices in a variety of locations, adjustability is not possible except by tying knots in the cords or by the limited adjustability provid-ed by the elasticity of the cord itself.

~, ' . ' , ' . ' "
'; ' ' ;' . ',' ' ' 1~68882 Therefore, it is usual to have a selection of such Bungee cords of varying lengths so that the required length can be selected depending upon circumstances.

SUMMARY OF THE INVENTION
The present invention overcomes these disadvantages of fixed lengths cords by providing a hook element and an elastomeric strap therefor which is adjustable as desired as to the position of the hook upon the strap and which furthermore is firmly clamped in the desired position as soon as the strap is extended as it would be during use.
' One aspect of the invention consists of a hook element for adjustable connection to an elastic type hold-down strap having a substantially rectangular cross section; said element comprising in combination a substantially U-shaped hooked one end, said hooked one end including a free standing leg and a `
further leg spaced therefrom, a connecting bar extending as an extension of said further leg, and a strap engaging other end formed on the distal end of said connecting bar, said strap en-gaging other end including a first strap engaging cross bar situated perpendicular to said connecting bar and a closed loop ~`-extending from said first cross bar and being spaced from said first cross bar to define an opening between said first cross bar and said closed loop, said opening being open on one side thereof and closed on the other side thereof to facilitate the engagement and disengagement of the associated hold-down strap.

strap having a substantially rectangular cross section; said hook element including a substantially U-shaped one end, one leg of said U-shaped one end continuing substantially spaced and parallel to the other leg thereof and forming a connecting bar, connected by one end thereof to said one leg, the other end of said connecting bar angulating substantially at right angles to said connecting bar and in the same plane as said U-shaped one end thus forming a first strap engaging cross bar, and then angulating substantially at right angles to lie parallel :
to but spaced away from said connecting bar, then angulating again substantially at right angles to lie spaced and parallel to said first cross bar and thereby forming a third cross bar, then angulating back towards said first cross bar and extending inwardly to form a second cross bar spaced and parallel to and lying between said first and third cross bars, thereby defining an opening between said first and second cross bars, said open-ing being open on one side thereof and closed on the other side ~ thereof. :~
:
A further aspect of the invention is to provide a de-vice of the character herewithin described which is simple in construction, economical in manufacture and otherwise well suit-ed to the purpose for which it is designed.

With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, my invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which:

DETAILED DESCRIPTION
Proceeding therefore to describe the invention in detail, the hook element collectively designated 10 is preferably formed from spring steel wire having a circular cross section, but it will be appreciated that other mate-rials and other cross sectional configurations can be used, depending upon design parameters.

i .~

:~
It is designed to be used with an elastomeric or resilient strap 11 which is in the form of a flat strap having a substantially elongated rectangular cross section-al configuration so that it is particularly suited for use - with the hook element as will hereinafter be described.

.
The hook element consists of a substantially U-shaped hook portion collectively designated 12 having a free ~tanding leg 13 on one side and a further leg 14 spaced and ' `: 106888Z
parallel therewith, with the substantially semi-circular curved portion 15 joining the inner ends of the two legs as clearly illustrated.

Leg 14 then continues in the form of a connect-ing bar 16, substantially spaced and parallel with leg 13 then terminates in a strap engaging other end collectively designated 17.

, : :' This strap engaging other end is formed by an-gulating the distal end of the connecting bar 16 substan-10. tially at right angles and towards leg 13 thus forming a ~ -first strap engaging cross bar 18 clearly illustrated in . the drawings. The portion forming the first cross bar 18 .! .
`c, then angulates again at right angles to form a portion 19 ~.

`~ which is substantially parallel to the connecting bar 16, ..

but extends in a direction opposite to the connecting bar .'~
; 16. It then angulates again substantially at right angles ~
:i to form a second cross bar 20 spaced and parallel to the first cross bar 18 and then extends upwardly as indicated --~r by reference character 21 and then inwardly to form a third cross bar 22 lying spaced and parallel and between the first ~ -and second cross bars 18 and 20 so that part of the portion 19, the portion 21 and the second and third cross bars 20 and 22, form a closed 1QP designated 23 in the drawings.

It will be observed that the said strap engaging ~s 25 other end is in the same plane as the hook end 12.
, .~ .

~ 1 ., .
' In use, the end of the strap 11 is first passed ~ ~
. ~.

: - 5 : - . . , .. . . .,, . ~ ,. .
~. . ., ; :, . : .,: , . .: . . -.. . .. . .. . . . ..

through the loop 23 from one side thereof and then passes over the third cross bar 22 and between the first and third cross bars 18 and 22, then curves over the first cross bar and again engages the closed loop 23 from the opposite side thereof so that it lies over the portion of the strap which first passed through the closed loop 23. The distal end of the strap 11 then exits and lies upon the standing part of the strap with this portion engaging behind the second cross bar 20.

The configuration and threading of this strap with the end 17 is clearly shown in Figures 3 and 4. This, together with the elastomeric material from which the strap is made of, enables the strap to readily be adjusted yet to clamp firmly in position as soon as tension is placed `~ 15 upon the strap which occurs when the strap is extended and the hook engaged upon anchoring point as is conventional.
~ , .

It will be appreciated that various sizes can be manufactured as desired.

Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit ; and scope of the claims without departing from such spirit ~

and scope, it is intended that all matter contained in the -accompanying specification shall be interpreted as illustra-tive only and not in a limiting sense.
