Description

in 150424

BACKGROUND OF THE INVENTION The present invention relates to a carrier belt with a gripper molding of electrical accumulators, in particular starter batteries.

In order to facilitate the transport of batteries, for example at workstations or charging stations, various gripping and lifting devices have been used in connection with the batteries.

For example, British Patent Specification 1,222,962 discloses a braided polypropylene support cord, the ends of which are accommodated in bores in the housing cover and molded into them by casting resin.

From U.S. Pat. No. 3,797,876, a carrier belt is also known which also consists of polypropylene and has thickened ends.

These ends are passed through two wide and two narrow holes in a special gripping strip at the edge of the box and in such a way that the thickings via side incisions are passed through the narrow holes which are smaller than the thicknesses.

A disadvantage of these known carrier strands is that by carrying a relatively heavy battery they will be able to cut into the palm of the hand.

Attempts have been made to remedy this disadvantage by means of assistance

of casings pulled over the carrier strings - cf. United States

U.S. Patent No. 3,092,520. However, these casings can be easily displaced 25 e, thus impairing the carrying properties.

According to the invention, a carrier of the kind mentioned initially is characterized in that a flattened gripping strip is inseparably attached to the carrier by injection molding 30 around the carrier.

Through the flattened molding and a rounding at the edges, such a gripping strip is well in hand, and it also has the advantage that it can be lowered into a recess and thus flush with the surface of the housing. The carrier cord is preferably a braided cord made of polypropylene. Also the grab bar may consist of polypropylene injection molded around the carrier cord.

The invention also relates to an apparatus for making a carrier cord. The apparatus is peculiar in that it consists of two mold gates with vertical in relation to the longitudinal axis of the gripper strip extending brackets for the cordel. This allows an impeccable injection of the cordella.

The invention will be explained in more detail below with reference to the drawing, in which 1 shows a carrier belt according to the invention with a gripper strip; FIG. 2 shows an apparatus for making a carrier belt with a gripping strip; and FIG. 3 Carrying strap with grab bar used in connection with a battery holder.

The FIG. 1, the gripping strip 1 is attached to a carrier cord 20 3. The gripper strip, like the carrier cord, is made of polypropylene.

It is made flat and is rounded along the edges. It is more than 8 cm long and has a width of more than approx. 1.5 cm. The thickness is about 0.5 cm. The gripping strip 1 is provided with slots 2. The slots 2 can be returned to the manufacture of the gripping strip, which is injection molded around the carrier cord 3. The gripping strip is manufactured by means of a spraying tool, e.g. consists of two mold parts 5 and 6. In these mold parts, the cord 3. is inserted the cord 3 by means of strips 4 which are offset relative to each other in the mold parts 5 and 6. After the closure of the mold parts, the support cord 3 is injected with polypropylene so that the moldings 4 of the finished product appear as slots 2. Without the moldings, impeccable re-spraying of the carrier cord would not be possible.

35 The carrier belt with the grab bar is attached to an accumulator in such a way that it is also possible to apply grab bars in the event that there is no recess in the accumulator container so that the stackability of the accumulator is maintained.

150424 A particular advantage of this recessed version of the handle is that a frame clamp can be used in a vehicle. For such a frame clamp, the handle must be able to be lowered. For this purpose, at opposite sides of the accumulator 5, the container 7 is provided, for example at the surfaces, a box-shaped projection 8. At the bottom 9 of this projection 8 there are some openings 10. The openings 10 serve to insert thickened ends 11 of the cord 3. thickened ends are inserted from below through insertion openings 12 of slots 10 13 ending in retaining openings 14. The holding openings 14 have a smaller diameter than the thickened ends 11 of the cord, so that the cord is held in this way. The fact that the middle portion of the bottom 9 of the box-shaped projection with the insertion openings 12 is raised relative to the 15 sides means that the ends 11 of the carrier cord will not be able to exit the slots 13. The cover 15 of the container is thus formed. the box-shaped projections are covered, and in this area there is a through-shaft 16 in the cover 20, so that a box-shaped projection 8 and the shaft 16 form a cavity for receiving the gripping strip 1, thereby fully integrating the gripping strip and the carrier cord into the periphery of the battery. . 25 Patent claims. A carrier belt with a plastic gripper molding list for electric accumulators, in particular starter batteries, characterized in that a flattened gripper strip (1) is inextricably fastened by injection molding around the carrier cord. 35 Carrying cord according to claim 1, characterized in that both the gripping strip (1) and the cord (3) consist of polypropylene.
