United States Patent 3,093,402 COMBINATIN CANE AND RETRIEVER Earl L. Sisson, Stratford, Conn., assignor to Clark Metal Products incorporated, Fairfield, Conn., a corporation of Connecticut Filed Dec. 29, 1960, Ser. No. 79,257 3 Claims. (Cl. 294-19) The present invention relates to a combination cane and retriever particularly for use by arthritic, lame or other incapacitated persons who are incapable of or have dithculty in bending over to pick up small articles, an obje-ct of the invention being to provide a sturdy cane which maybe used in the manner of ya conventional cane, and having retriever means at the tip end of the cane adapted for convenient operation by means associated with the handle of 'the cane, so that the thumb or the linger of the hand gripping the handle may be employed to actuate the retriever means.

A further object is to provide a combination cane and retriever having a rubber tip removably engaged upon the tip end of the `cane and which has the dual purpose of providing the conventional non-slipping tip for the cane as well as a protective closure for the retriever means in its retracted inoperative position. A further object is to provide such rubber tip having novel means for retaining it in position upon the cane and which permits of its ready removal and replacement Ifor the purpose of utilizing the retriever means.

Other objects and advantages will become apparent from a consideration of the yfollowing detailed description taken in connection with the accompanying drawings wherein a satisfactory embodiment of the invention is shown. However, it will be understood that the invention is not limited to the details disclosed but includes all such variations and Inodilications as fall Within the spi-rit of the invention and the scope of the appended claims.

In the drawings:

FIG. 1 is .a side elevation of a combination cane and retriever according to the invention;

FIG. 2 is a sectional View on an enlarged scale and partially broken away showing the combination cane and retriever in its normal inoperative position with the rubber tip in place;

FIG. 3 .is a horizontal sectional View taken along the line 3-3 of FIG. 2;

FIG. 4 is a sectional View of the rubber tip removed from the cane;

FIG. 5 is a sectional View showing the retriever means in its projected open position; and

FIG. 6 is a sectional view of the tip end of the cane showing the retriever means in partially retracted closed position.

Referring to the drawings, the combination cane and retriever according to the invention comprises a tubular shaft 10, preferably of steel, provided upon its upper end with a laterally extending handle 11, preferably of molded plastic material, secured to the shaft by engaging the upper end of the shaft in the opening of an annular internal ange 12 at :the lower end of the hub portion 13 of the handle, the shaft being provided with a crimped bead 14 engaging the lower side of the flange 12 and a retaining tiange 15 bent outwardly at its upper edge upon the upper side of the flange 12. The hub portion 13 is provided with a cylindrical pocket 16 in axial alignment with the shaft in which there is slidably tted a push button 17 secured by a cross-pin 18 upon the upper end of a push rod 19 extending downwardly in the shaft through a lianged bearing bushing 20 seated within the upper end of the shaft. A helical expansion spring 21 is engaged about the rod between the bus-hing 20 and the lower end of the push button 17, the latter having a recess 22 in its lower end in which the upper end of the spring is seated. The spring exerts pressure upon the button to normally draw the rod upwardly within the shaft to retract the retriever member 23 connected to its lower end, as seen in FIG. 2.

The retriever member 23 is formed of a band of spring tempered metal, preferably spring steel, having a gen erally hair pin shape and consisting of a pair of side legs 214-24 joined at their upper ends by a knob like bight 25 engaged in the notched lower end 26 of the rod 19 and secured by swaging the sides of the notched ends inwardly beneath the knob like hight. The upper portions 27 of the side legs are straight and are normally pressed against each other in parallel relation, as seen in FIG. 2, the intermediate portions 2S are inclined and diverge downwardly, and the lower portions 29 are straight and normally disposed in parallel spaced relation, being provided at their lower terminal ends with outwardly bent shoulder portions 30 and inwardly bent finger portions 31 which are normally in opposed contacting relation with each other.

In upwardly spaced relation to the lower end of the shaft lo there is provided an inwardly embossed annular rib 32 dening a restricted opening with-in the shaft and which is normally engaged by the lower end portionsv 29 of the retriever member to retain its side legs in closed position, the shoulder portions 30 in this closed position being disposed beneath the rib and thus acting as stops to limit the upward movement of the rod 19 under the pressure of the spring 21. The rib 32 also defines a pocket in the lower end of the shaft of greater depth than the height of the shoulder portions 30 above the linger portions 31, so that in the fully retracted position the linger portions are enti-rely within the pocket.

The rubber tip 33 is provided with a pocket 34 having a metal disk 35 seated against its base and which normally provides a rigid cover for the lower end of the rod 19 to protect the retracted retriever, the latter being slightly spaced upwardly from the disk in the retracted position, as seen in FIG. 2. An internal annular rib 36 is provided upon the wall of the pocket 34 which snaps into the external annular groove 37 provided by the inwardly embossed annular rib 32 of the shaft, so that while the tip is normally etlectually retained in place it may be readily removed or re-engaged by virtue of the flexibility of its side wall enabling the rib 36 to be snapped into and yout of the groove 37. It will be noted that the annular rib 32 serves a three-fold purpose: one, it provides a stop means to limit the retracted position of the retriever; two, it provides the external groove 37 for retaining the rubber tip; and three, it functions as a cam to draw the projected open retriever into closed position during its retraction, `as will presently more fully appear.

In operating the retriever the rubber tip is removed and thereupon the retriever is projected by depressing the button 17, as seen in FIG. 5, the spring tension of the side legs of the retriever causing them lto spring outwardly to their open position as the intermediate inclined portions 28 of the side legs come into position within the opening of the annular rib 32. In the open position small articles, pieces of paper, or the like may be readily engaged within the open retriever and through release 0f the button 17 the retriever is retracted and closed as the lower portions 29 of the side legs come into the opening of the annular ribl 32, thus gripping the retrieved articles as the retriever moves to its partially retracted position as seen in FIG. 6. The retriever may be retained in this partially retracted position either by continuing pressure upon the button 17, or by the gripped article engaging the lower end of the shaft to hold the retriever in its partially retracted position. raised from the iloor or ground as desired itis released by again depressing the push button 17 to open the retriever member. Thereupon the spring 21 retracts the retriever member to its closed position, as seen in FIG. 2, and the rubber tip 33 is replaced to enclose and protect the retriever and enable the conventional use Of the cane.

What is claimed is:
