DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a handling aid for lifting and transporting loads, having a hand grip and a bracket which is connected to the ends of said hand grip and to which it is possible to connect retaining or lifting means, such as sling chains, hooks, eyelets or gripping tools.
A handling aid, designed as a gripper hand tool, of the type in question is known, and a pin of a connection fork for a hook is mounted rotatably in the bracket of said handling aid. This handling aid leaves something to be desired since it can only be used for special applications.
SUMMARY OF THE INVENTION
The object of the invention is to provide a handling aid which permits rapid and convenient exchange of retaining or lifting means and consequently can be used for a wider variety of applications than the known handling aid. This object is achieved according to the invention in that, in the case of a handling aid of the generic type, the bracket has at least one longitudinal slot at whose end facing the hand grip there is arranged an introduction opening for parts of the retaining or lifting means, which parts are supported on those sections of the bracket which bound the longitudinal slot, and in that the longitudinal slot extends from the introduction opening into the vicinity of the vertex of the bracket.

DESCRIPTION OF THE BEST MODES FOR CARRYING OUT THE INVENTION
The handling aid represented in FIGS. 1 to 6 has a hand grip 1 and a bracket 2 which comprises two bracket halves 3 and 4. The hand grip 1, which is equipped at its ends with eyelets 5 and 6 for the attachment of shackles (not shown), has a slightly convex shape and is provided, on its side facing the bracket 2, with grip hollows 7, 8, 9, 10 for the fingers of the user, this permitting it to be positioned comfortably in the hand. The top of the hand grip 1 defines a substantially straight edge.
In the immediate vicinity of the ends of the hand grip 1, the arcuate bracket 2 has introduction openings 11 and 12, which are adjoined by longitudinal slots 13 and 14. Fitted into the longitudinal slot 14 is a link 15 of a length of chain which forms a retaining or lifting means 16 and at whose free end a hook 17 is fastened. The length of chain is retained by a part 18 which is formed by a link and is supported in a hollow-like guideway 19 on that side of the bracket half 4 which faces the hand grip 1.
The top ends of two pins made of elastic material project into the longitudinal slot 14, in the vicinity of the introduction opening 12, and the tips of these pins form latching protrusions 20, 21 for the link 15 and prevent said link from slipping out of the longitudinal slot 14 when the length of chain is relieved of its load.
In the region of the vertex 22 of the bracket 2, the latter has a stop 23 which is formed by a reinforcement web and is intended for the link 15 of the retaining or lifting means 16.
Extending from the introduction opening 11 is a guide duct 24, into which there is guided a head-like part 26 which is arranged at the end of a retaining rod 25, is formed by a body of rotation, and is supported on that section of the bracket half 3 which bounds the longitudinal slot 13. In the case represented, a retaining or lifting means 27 formed by a g
