HANDLE Filed Sept. 7, 1951 (E re United States Patent HANDLE Application September 7 195 1, Serial N 0. 245,582

'5 Claims. (Cl. 74-543) This invention relates to handles, and particular to handles for hand operated air pumps and the like. A handle in accordance with the illustrative embodiment of the invention is the subject of an application for design patent, Serial No. D. 16,554, now Design Patent No. 172,689, filed on even date herewith.

The object of the invention is to simplify the construction as well as the. means and mode of operation of handles whereby such handles may not only be economically manufactured, 'but will be more eflicient and satisfactory in use, adaptableto a wide variety of applications, having relatively few parts and unlikelyfito get. out f repa r. j

A further object of the invention is to obtain a handle of simple and inexpensive construction of general application to air pumps and like devices wherein a piston is reciprocated by hand through pressure and return strokes.

Another object of the invention is to utilize in a pump or the like a handle molded from a soft, resilient and deformable material.

A further object of the invention is to present a molded handle as described constructed and arranged as a conventional handle but to absorb in its base the thrust of the operators hand on the pressure stroke.

Still another object of the invention is to provide a simple and effective means for attachment of the molded handle to the piston rod.

A further object of the invention is to provide a handle possessing the advantageous structural features, the inherent meritorious characteristics and the mode of operation herein described.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention intended to be protected by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation, as hereinafter described or illustrated in the accompanying drawings, or their equivalents.

Referring to the accompanying drawings, wherein is found the preferred but obviously not necessarily the only form of embodiment of the invention,

Fig. 1 is a perspective view of a handle embodying the present invention;

Fig. 2 is a side view thereof, a portion being shown in section;

Fig. 3 is a transverse sectional view; and

Fig. 4 is a perspective view of the insert.

Like parts are indicated by similar characters of reference throughout the several views.

Referring to the drawings, a handle in accordance with the illustrative embodiment of the invention includes a grip member 11 made of a relatively soft, resilient and deformable material, for example rubber or rubber substitute. The member 11 is molded in a single piece and comprises a generally rectangular base or body portion 12 made relatively thick.

A strap 13 merges with the ends of the body 12 and extends in spaced overlying relation thereto, the strap being relatively thinner than the body and tapering both as to. width and thickness as it extends from the body 12.

Theunderside or lower surface of the body 12 is flat. The top side or upper surface thereof isformed with undulations 14- arranged to receive the backs of the fingers: of the operators hand. Thus, in gripping the handle the strap 13 is accommodated. in the palm of the hand while, the back of the fingers at or adjacent the knuckles overlie the. undulations 14. On the upward stroke of the handle, which is effected under light or no resistance, a pulling force is exerted through the strap 13.. On the downward stroke, which is the. pressure stroke, the opera-tor. presses against the relatively soft body 12 with a. closed fist, the backs of the fingers being receivedv between the undulations 14.

There is longitudinally disposed .in the base or body 12 a reinforcement bar 15. The bar 15 is flat and rectangular, conforming substantially to the shape of the body 1 2., and is embedded in: the. material of the handle as a part of the molding operation.

.For attachment of the handle to the piston rod or shaft, a stem orstud 16 is secured to the bar 15 and projects from the bottom thereof in perpendicular relation to the bar. The stem. 16 is preferably integrally united with the'ba'r 1 5 andi's relatively short, projecting through and beyondthe'body 12 only a distance. sufficient to permit it to be received in a tubular sleeve 17 representing the piston rod. In its projecting portion, the stem 16 has an indented formation 18, formed in the side surface of the stem by annular grooving, notching or the like. Opposite or in line with the indented formation, the wall of the sleeve 17 is crimped into such formation. Relative axial motion between the stem and sleeve thereby is inhibited. The connection effected by crimping in the wall of sleeve 17 is sufficiently positive as to sustain the retracting or upward stroke of the handle. It is not,'however, relied on to sustain the whole of the greater axial thrust exerted during the downward or pressure stroke, this thrust being in the main absorbed by the sleeve directly, the upper end thereof being extended to abut the lower surface of body 12.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise but one of several modes of putting the invention into effect.

Having thus described my invention, I claim:

1. A one-piece unitary handle made of a relatively soft resilient and deformable material, including a relatively thick approximately rectangular body portion and a hand grip portion extending as a relatively thin strap from the ends of said body in spaced overlying relation thereto, the upper surface of said body having an undulating formation to receive the backs of the fingers of the operators hand.

2. A handle according to claim 1, characterized by a reinforcing bar embedded in said body portion beneath the surface thereof.

3. A handle for a pump or the like, including a relatively thick generally rectangular body and a hand grip portion extending as an integral strap from the ends of said body in spaced overlying relation to said body, the upper surface of said body having an undulating formation to receive the back of the fingers of the operators hand and said body and strap being formed of a relatively soft resilient and deformable material, a reinforcing bar embedded in said body, and a stem secured to said bar and projecting perpendicularly therefrom through the lower surface of said body.

4. A handle for a pump or the like, including a generally rectangular body and an integral strap merging with the ends of said body and extending in spaced overlying relation to said body, said body and strap being formed of a relatively soft resilient and deformable material and said body being relatively thicker than said strap and having an undulating formation in its upper surface, a reinforcing bar embedded in said body, and a stem integrally united with said bar and projecting perpendicularly therefrom through the lower surface of said body, said stem being formed outside said body with a formation for attachment of the handle with means operated thereby.

5. A handle assembly for a pump or the like, including a grip member made of a relatively soft, resilient and deformable material and having a relatively thick base portionand an overlying relatively thin strap portion, the side of said base portion facing said strap having an unulating formation to receive the backs of the fingers of the operators hand, a stem of a relatively rigid unyielding material received in said base portion on the opposite side thereof and projecting therefrom, the projecting part of,

said stern being indented in the side surface thereof, a

tubular sleeve receiving said stem, said sleeve having a portion crimped into cooperative engagement with the indented formation on said stem, a reinforcement bar embedded in said base portion and of the same material as said stem, said bar and stem being integrally united.
