Removable toggle link

#This invention relates to a removable shackle or link. More particularly, the invention relates to a link removably insertable in an apertured member for the purpose of securing a chain, rope, cable or the like.

#There are numerous applications requiring a loop or hook to which is secured a chain or similar flexible tie. One such example is exemplified in the hauling of automobiles on a transport trailer. It is necessary to secure the automobiles to the trailer by means of tie-down chains. Numerous devices are presently in use which are typically welded to the framework of the trailer in order to secure the chains. The location of such devices on the trailer naturally depends upon the dimensions of the vehicle to be secured. If the tie-down devices are arranged to secure a vehicle of a particular size, and it is then necessary to secure a different sized vehicle, the tie-down devices must be re-located. This commonly involves cutting the device from the trailer frame and re-welding it at a new location. The expense of time and labor are substantial drawbacks to this method.

#Consequently, there is a need for a removable link or shackle which can be readily positioned at various locations on the trailer frame. The primary object of this invention is to meet this need.

#In the accompanying drawing, which forms a part of the specification and is to be read in conjunction therewith, and in which like reference numerals are employed to indicate like parts in the various views:

#FIG. 1 is a perspective view of a removable link constructed in accordance with a preferred embodiment of the invention;

#FIG. 2 is a side elevational view of the link shown in an open position to be inserted through an aperture of a plate member;

#Referring to the drawing in more detail, the link basically comprises a bifurcated closed loop formed by first and second hook members 10 and 11. The first hook member 10 includes a base or toggle 10a which is integrally joined approximately at a right angle at the inner end thereof by a shank 10b. The shank 10b, in turn, is integrally joined with a bight or hook portion 10c which extends upwardly from the shank and presents a uniform curve to the end 10d of the hook portion. The end 10d terminates short of the shank 10b or hook portion 10c in order to provide an opening to the bight of the hook portion 10c. Thus, the hook member 10 is generally in the shape of the numeral "2". The back surface of the "2" is flat and lies in a common plane, while the front and side surfaces are contoured in relief from the back surface as illustrated. In section (FIG. 5), the hook portion 10c is substantially quarter-round.

#The second hook member 11 is identical in configuration to the first hook member 10 and includes a toggle 11a integrally joined approximately at right angles at the inner end thereof by a shank 11b. The shank 11b, in turn, integrally flows into the bight or hook portion 11c which extends upwardly from the shank 11b in a uniform curve to the terminal end 11d.

#With the flat surfaces (i.e., back plane) of each hook member 10 and 11 in confronting arrangement, the members 10 and 11 are pivoatlly pinned together, as by a rolled pin 12, at the junctures of the shanks 10b and 11b with the bases 10a and 11a. In the closed position as illustrated in FIG. 1, the toggle bases 10a and 11a of the hook members extend in opposite directions and the shank 10b and 11b and bight 10c and 11c portions form a continuous, teardrop loop. As illustrated in FIG. 5, the bight portions 10c and 11c in section form a substantially half-round interior surface to facilitate coupling engagement with a ring 13 or the like.
