The legs of the core are covered with molded bodies of hard plastic material and runner bars of the same plastic material of reduced section extend between the ends of the molded bodies in addition to the central portion of the core. A filler of soft material is folded onto the central portion of the bars and core to provide a comfortable gripping area, and this filler may be provided with an outer covering of sheet material.

14 Claims, 11 Drawing Figures PATENTEDAPR 18 I972 SHEET 2 BF 2 INVENTORS [00 E Male/ 5 362/4 6; $2 450 TTORNEY LUGGAGE HANDLES This invention relates to luggage handles, and particularly handles molded of hard synthetic plastic materials which are reenforced with rigid bars extending therethrough and which, in addition, are provided with soft gripping portions.

It is the object of the present invention to provide rugged and economical luggage handles which may be molded at low cost from synthetic plastics, which incorporate core reenforcements in addition to plastic runner bars of diminished cross-section at the central portions of the handles, around which may be connected gripping portions of soft material, which may or may not be provided with a covering on the exterior thereof.

It is another object of the invention to provide a rugged luggage handle which incorporates a wire-core reenforcement and which, in addition, is provided with a light-weight central portion cooperating with the wire reenforcement so that a soft padding material may be combined therewith to afford a gripping portion which is comfortable, esthetic in appearance, and lasting.

Other objects and purposes will appear from the following detailed description of the invention, taken in conjunction with the accompanying drawings, wherein FIG. 1 is a front view of the luggage handle in accordance with the invention, partly in elevation and partly in section;

FIG. 2 is a vertical sectional view along line 22 of FIG. 1;

FIG. 3 is an enlarged sectional view of the upper portion of FIG. 2;

FIG. 4 is a front view of the molded handle before the central gripping portion is applied thereto;

FIG. 5 is a front view of a second embodiment of the luggage handle in accordance with the invention, partly in elevation and partly in section;

FIG. 6 is a vertical sectional view along line 6-6 of FIG. 5;

FIG. 7 is an enlarged sectional view of the upper portion of FIG. 6;

FIG. 8 is a front view of the molded handle frame shown in FIG. 5, before the gripping portion is applied thereto;

FIG. 9 is a fragmentary front view of the handle shown in FIG. 5, with a modified fastening for the outer covering;

FIG. 10 is an enlarged vertical sectional view along line l0 10 of FIG. 9; and

FIG. 11 is a fragmentary perspective view of the metallic fastening plate shown in FIGS. 9 and 10.

In the drawings are shown a bail-shaped luggage handle H comprising a wire core reenforcement of metal or other rigid material constituted by a central portion 1 wherefrom extend

lateral legs

2,2, which terminate at their free ends in

pintles

3,3, respectively. The lateral legs of the reenforcing bar are embedded within bodies of hard

plastic material

5,5, of any desired curvature and cross-section, which are molded around the reenforcing bar by known injection or compression molding procedures, leaving free the terminal ends of the

pintles

3 and 3 for connection to the hardware affixed to any item of luggage or carrying cases, as is well known in the art.

The ends of the molded bodies or

legs

5,5 remote from the pintles terminate in

edges

6,6 between which extend runner bars 7 and 8 of the same plastic material of which the

legs

5,5 are molded. In fact, these runner bars serve as material feedchannels which allow the gating on one side only of the mold to fill the entire mold during the casting operation. The provision of these runner bars of plastic material, in addition to the reenforcing core, results in a reduction of the amount of molding material required for the handle, without reducing the strength or the loading capacity thereof.

The handle is completed by providing a filler 10 of soft material, at the central portion between the

edges

6,6. This filler member may be of a molded spongy texture such as polyurethane foam, which preferably is formed in one piece and folded at the median line 11 of the internal surface of the molded body, so that the filler embraces both the runner bars 7 and 8, as well as the reenforcing bar 1, as shown in FIGS. 2 and 3.

The interior surface of the soft handle portion 10 may be provided with grooves 13 to accommodate the contours of the runner bars and reenforcing bar or, if desired, the internal surfaces of the filler portion may be smooth, reliance being had upon the yieldability of the foam material to adapt its contours to the shape of the bars extending across the arch of the bandle.

If desired, the juxtaposed edges 12 of the two halves extending from the hinge line 11 may be united with adhesive, especially so if the filler has an external skin surface of such appearance and texture which does not require an outer covering.

In the illustrated embodiment, an outer covering 15 of sheet material, which may be of leather, plastic, fabric, or any other sheeting, is applied to the external surface of the filler and is sewed by stitches 16 to encompass the molded body of the filler. This stitching can be executed by conventional sewing or stitching operations, as well as by riveting or by heat seaming developed by ultrasonic or radio-frequency energy.

The color and texture of the covering 15 may be selected to blend with the colors and finish of the plastic

lateral legs

5,5.

The provision of the multiple bars in the plane of the pintles results in a reduction in the amount of molding material for the handle, without sacrificing any strength characteristics thereof, while imparting maximum carrying comfort by virtue of the filler of soft material which complements the handle assembly at the central portion thereof.

Another embodiment of the invention is illustrated in FIGS. 5 to 8. In this construction, the reenforcing bar is composed of a central portion 21, from the opposite ends of which diverge the

leg portions

22 and 22, which terminate in outwardly directed

pintles

23,23, respectively. The

lateral legs

25,25 are shaped in any desired manner in encompassing relation to the

portions

22,22 of the reenforcing bar. The bar may be of different sections other than circular and, in fact, may be formed of any strong rigid material other than metal.

In this embodiment, the outermost runner bar 27, of cylindrical outline, extends between the

inner edges

26,26 of the

legs

25,25. The second runner bar is molded integrally with the reenforcing bar 21 which may extend centrally thereof or eccentrically, as shown in FIGS. 6 and 7.

The filler 30 of sponge material, such as polyurethane foam, is folded around the

bars

28 and 27 and is maintained in close contact with the

runner bars

27 and 28 by means of a covering 35 of leather, fabric or plastic sheet material which may, in addition, be provided with perforations 38 on its entire surface or only at the bottom portion thereof, whereat the same is carried in the hand. This improves the grip of the handle and also induces ventilation of the handle.

As shown in FIG. 6, stitches 36 serve to unite the opposite edges of the cover 35. These stitches may be formed by threads, or they may be imitation stitches if the opposite edges of the Sheet are united by heat seaming. The covering may be composed of several parts instead of being an integral piece of sheeting.

FIGS. 9 to 11 show an alternate mode of uniting the opposite edges of the outer covering sheet 35. In this case, a channel-shaped clamp 40, of sheet metal, provided with barbs 41, is superposed upon the mating edges of the cover sheet, so that upon penetration of the barbs into the latter, the sheet serves to encase the molded filler of soft material at the central part of the handle.
