LUGGAGE HANDLES
Abstract
A composite luggage handle formed of a bail-shaped reenforcing
core of rigid material having a central portion and two lateral
legs diverging from the ends thereof which terminate in mounting
pintles. 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.

Description
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 2--2 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 10--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 feed-channels 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 handle.
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.
