9 Claims.

This invention relates to improvements in door handles, drawer pulls and like hardware articles.

The main objects of this invention are:

First, to provide a hardware article of the door handle type which may be very economically produced in a wide variety of shapes and at the same time is economical in structure and strong and durable.

Second, to provide an article of hardware of this type in which the exterior is formed of moldable thermoplastic material and may be made in a wide variety of designs so far as longitudinal and transverse conformation is concerned and in a wide range of colors for adapting the same to finish and color schemes of related parts.

Objects relating to details and economics of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.

Preferred embodiments of the invention are illustrated in the accompanying drawing, in which:

Fig. 1 is a fragmentary side elevation partially in central longitudinal section on line l--l of Figs. 2 and of a door handle embodying our invention.

Fig. 2 is a fragmentary front elevational view, the casing being partially in transverse longitudinal section.

Fig. 8 is a fragmentary side elevational View partially in central longitudinal section of an adaptation of our invention to a drawer pull.

Fig. 9 is a cross section on line 9-9 of Fig. 8.

In the embodiment of our invention illustrated, I designates the spindle or chill of a door handle, the outer end of this spindle terminating in'a laterally turned arm 2 as shown in Fig. 1. 3 is a combined supporting bearing and escutcheon unit.

In Figs. 1 to 7 inclusive, we illustrate our invention as embodied in a door handle. In this embodiment, we provide a tubular longitudinally curved handlebar or core member 4 formed of 2 sheet metal. This core member is longitudinally and transversely conformed or shaped to the desired design. At its base end, the core member has a rearwardly facing opening il receiving the spindle. The arm of the spindle is curved to fit against the outer wall 5 of the handle bar and is Welded thereto at 6, thus providing a rigid connection for the sheet metal handle bar or core to the spindle arm, the spindle arm constituting a reinforcing and supporting member for the sheet metal handle bar or core so that it may be formed of quite light gauge stock and still possess rigidity and strength and this is particularly true inasmuch as the member 4 is of tubular section.

The handle bar or core member has a heel portion 1 which extends rearwardly beyond the spindle as is clearly shown in the drawing. At its inner side, the handle bar or core member has a longitudinal slot 8 extending from the opening 4| at its base end to its tip.

The tubular casing 9 is preformed of material that is commonly known in the art as thermoplastic material, this material being of a non-metallic nature and rendered plastic and moldable by heat. Tenite is a suitable example but other moldable thermoplastic materials may be used. The casin 9 is cross-sectionally shaped to closely embrace the handle bar or core member and is preferably in supported engagement therewith throughout as is illustrated .in the longitudinal and sectional views of the draw- The side walls H] of the casing are in practice preferably plasticized and molded around the side and inner walls H of the core member and the edges [2 of the casing are turned inwardly into interlocking engagement with the longitudinal slot 8, see Figs. 1, 3, 5 and 6. The inturned portions I2 are plasticized and turned inwardly and the inturned portions are preferably in side by side abutting relation as shown at IS, the width of the groove being substantially twice the wall thickness of the casing. By reference particularly to Figs. 5 and 6 it will be noted that the longitudinal edge portions of the tubular core member 4 adjacent the longitudinal slot 8 thereof are disposed in planes substantially at right angles to the inturned edge portions l2 of the casing 9 which are disposed in said slot. This facilitates a relatively strong handle structure of substantial cross sectional area from a relatively small amount of metal in the core member 4 and thermoplastic material in the tubular casing 9. The edges of the heel portion of the casing are turned inwardly at I 4 around the edges of the heel portion of the handle bar or core, see Figs. 1 and 4. This not only effectively secures and integrally unites the casing to the handle bar or core member but it provides a very attractive structure, there being no exposed metal parts and therefore no finishing of metal parts is required.

The casing being formed of thermoplastic material, as previously described, may be of a wide range of colors and forming the core member or. handle bar of sheet metal, it maybe readily formed in quite a wide range of designsthat is,

so far as longitudinal curvature or shape and cross-sectional shape is concerned.

In Figs. 8 and 9, we illustrate our invention in a drawer pull designated generally by the numeral [5. In this structure, the handle bar or core member I6 is symmetrical at each end and is provided with inwardly facing base openings IT. The attaching member It is disposed within and welded to the walls of the core member at IS. The casing 2i! is formed of thermoplastic moldable material and in this case is conformed longitudinally and cross-sectionally to the core member as has been described. The core member l6 has its longitudinal edges slightly spaced from each other forming a longitudinal slot 2'! extending between the openings ll. The edges of the casing are turned inwardly into the slot as shown at 22 substantially as in the handle embodiment which has been described. The edges 23 are flanged inwardly around the edges of the base opening I! substantially as in the handle embodiment.

We have illustrated and described two embodiments which we consider highly practical. We have not attempted to illustrate or describe other embodiments or adaptations as we believe this disclosure will enable those skilled in the art to embody or adapt our invention as may be desired.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:
