DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device for facilitating the carrying of bags having loop handles, or other loads such as tied up parcels, paint pots, ski boots, etc., that are capable of being hooked to said device.
A grip for facilitating the carrying of lightweight packages closed by means of a tie has been proposed (FR-A-1.356.457), and is constituted by a tube made of wood or cardboard in which a metal shaft, ended at each of its ends by a hook, passes in order to enable the string surrounding the package to be transported to be hung thereon.
This grip, made out of two heteroclite materials (wood/metal or cardboard/metal), has the following disadvantages: uncomfortable, due especially to the rigidity of its central body which does not generate any shock absorbing effect during walking, the shocks resulting from the oscillations caused by the carrier's walk being integrally transmitted to his hand and arm, these shocks further promoting the ill-timed tearing of the hanging bags; distribution of the loads at the ends of the grip, in view of the straightness of its rigid central body and of the invariable position of the suspension points of said loads, the carrier's hand thereby being constantly biased to resist this lack of balance; reasons, the application of a too heavy load at its ends can cause the irreversible bending of the cardboard, and even the tearing thereof, with possible unfortunate consequences for the carrier's hand which is then put into contact with the wire (shearing of the fingers)
To remedy this latter disadvantage, the document FR-A-388.910 proposes a grip, still made of heteroclite materials, but whose central portion is made of a flexible material, such as leather. However, the flexibility of the leather is limited, such that after several uses of the grip under substantial loads, it does no longer recover its initial shape. In addition, it does not permit any absorption of the shocks caused by the carrier's walk.
The object of the invention is especially to remedy these disadvantages and deficiencies of the carrying grips described in the aforementioned documents.
According to the invention, this goal is achieved due to a carrying grip whose central body forming the grip itself is made of a material having an elastic deformation capability, and in that said body includes two flexible portions or arms that are superposed, spaced apart and separated by an elongated opening extending between the end zones constituting the hooks.
The carrying grip comprising the aforementioned characteristics procures numerous advantages.
The flexibility of the grip provides an exceptional comfort during the transport of loads, on the one hand, and imparts a very substantial stability to the grip, when the latter is loaded, on the other hand.
The comfort results from the flexibility of the central portion which plays the role of a shock absorber, and thus considerably reduces the shocks caused especially by the oscillations from a user's walk.
This characteristic thus makes it possible to eliminate the pain caused to the hands by the loop handles, as well as the risks of an ill-timed tearing of the bags.
The stability is acquired by the curvature of the grip that assumes the shape of an inverted "U" under load, which makes it possible to offset the points of application of the three parallel, but opposite, forces that are exerted on the grip, namely: two downward vertical forces at the ends, and one upward vertical force in the center.
This offset creates a polygon of forces whose equilibrium is all the more stable as the loads will be heavy and the curvature, consequently, substantial, even in the case of an unequal load distribution.
The grip cannot break abruptly in view of the fact that in the case of too heavy loads hanging from its ends, it is the abutment or one of its arms that will break first, such that the carrier will be alerted and will have the time to put the bags down on the ground before the grip breaks completely.
The grip can be placed comfortably on the fore-arm or "slung" over
