Abstract
A retractable trash spear device comprises an elongated tubular handle member having opposite ends with an elongated rod element therein having a pointed end and being axially movable between an extended position with the pointed end projecting from one end of the handle member and a fully retracted position with the pointed end completely within the handle member. The handle member has an elongated slot formed therein adjacent its other end, and a manual actuating element is adjustably attached to the rod element and extends out of the slot for selectively moving the rod element between its retracted and extended positions. A coil spring in the handle member surrounding the rod element biases the rod element towards its retracted position. The lower end of the slot in the handle member has a right angle extension thereon for holding the actuating element thereby to hold the rod element in its extended position.

Description
Background of the Invention
1. Field of the Invention
This invention relates generally to trash spear devices.
2. Description of the Prior Art
Spear devices have been used for many years for retrieving litter from the ground and commonly comprise a stick having a pointed object on one end thereof, such as a nail, for impelling trash thereon. Such prior trash spear devices are hazardous by reason of the pointed end and further, the trash impelled thereon must be manually removed therefrom. It is therefore desirable to provide a trash retrieving device of the spear type which eliminates much of the hazard of prior spear devices and the requirement of manually removing trash therefrom.
Summary of the Invention
A retractable trash spear device comprises an elongated tubular handle member having opposite ends. An elongated rod element is disposed in said handle member and has a pointed end, the rod element being axially movable between an extended position with the pointed end projecting from one end of the handle member, and a fully retracted position with the pointed end substantially completely within the handle member. The handle member has an elongated slot formed therein adjacent its other end, and a manual actuating element is attached to the rod element at a point spaced from the pointed end and extends out of the slot for selectively moving the rod element between its retracted and extended positions. Spring means is provided in the handle member for biasing the rod element toward the retracted position, and means is provided for selectively holding the rod element in its extended position. In one embodiment of the invention, an enlarged, flat member is secured to the one end of the handle member so that the device can also be used for compacting trash in a receptacle.
It is accordingly an object of the invention to provide an improved retractable trash spear device.
Another object of the invention is to provide an improved retractable trash spear device additionally usable as a trash compactor.
The above-mentioned and other features and objects of this invention and the manner of attaining them will become more apparent and the invention itself will be best understood by reference to the following description of an embodiment of the invention taken in conjunction with the accompanying drawings.

FIG. 1 is a side elevational view of the improved retractable trash spear device of the invention in its extended position;
FIG. 2a is an enlarged, side, cross-sectional view showing the upper part of the device of FIG. 1 in the retracted position;
FIG. 2b is a side, cross-sectional view showing the lower portion of the device of FIG. 2a;
FIG. 3 is a fragmentary, side elevational view of the upper portion of the device of FIG. 1 with the hand grip member removed; and
FIG. 4 is a fragmentary, side, cross-sectional view showing an embodiment of the invention additionally usable for compacting trash.
Description of the Preferred Embodiment
Referring now to FIGS. 1-3 of the drawings, the improved retractable trash spear device of the invention, generally indicated at 10, comprises an elongated tubular handle member 12 having open top end 14 and open bottom end 16. Elongated, axially extending slot 18 is formed in handle member 12 extending downwardly from top end 14 and having right angle extension 20 formed in its bottom end for a purpose to be hereinafter described.
Elongated rod element 22 is provided disposed in handle member 12 and having top end 24 and sharp pointed bottom end 26. Rod element 22 is selectively movable between an extended position with pointed end 26 projecting from bottom end 16 of handle member 12, as shown in FIG. 1, and a fully retracted position completely within handle member 12, as shown in FIGS. 2a and 2b.
In order to move rod element 22 between its extended and retracted positions, ferrule member 28 is slideably mounted on rod element 22 at a point adjustably spaced from bottom end 26. Manual actuating member 30 has its inner end 32 threaded in opening 34 in ferrule member 28 to engage rod element 22, inner end 32 of actuating member 30 extending outwardly through slot 18. The threaded engagement of inner end 32 of actuating member 30 in opening 34 in ferrule member 28 permits axial adjustment of ferrule member 28 on rod element 22, thereby selectively to determine the desired extend of the projection of pointed end 26 from end 16 of handle member 12 in the extended position, and to accommodate periodic sharpening of end 26 which reduces the overall length of rod 22. Movement of actuating member 30 to the right, as viewed in FIGS. 1 and 3, in its lower position at the bottom end of slot 18 so that inner end 32 enters right angle extension 20, as shown in dashed lines at 32a in FIG. 3, serves to retain rod element 22 in its extended position.
Spring seat member 38 is retained in end 16 of handle member 12 by suitable threaded fastener 38 and has central opening 40 therein through which pointed end 26 of rod element 22 extends in the extended position. Spring seat member 42 is slideably mounted on rod element 22 in handle member 12 and is adjustably secured to rod element 22 by suitable set screws 44. Coil spring 46 surrounds rod element 22 in handle member 12 and has its opposite end 48, 50 respectively engaging spring seat members 36, 42, thereby biasing rod element 22 to its retracted position, as best seen in FIG. 2b. Handle grip member 52 formed of suitable resilient material is positioned on top end 14 of handle member 12 and exposes the operating section of slot 18.
It will now be seen that the hazard of prior trash retrieval spear devices is greatly reduced with the improved retractable spear device of the invention since pointed end 26 of rod element 22 need only be extended during the operation of retrieving trash from the ground and may at other times be retracted. Further, it will be seen that trash may be removed from pointed end 26 and deposited in a suitable receptacle by merely retracting rod element 22 and thus, the user need not touch the trash or debris on pointed end 26.
Referring now to FIG. 4 in which like elements are indicated by like reference numerals and similar elements by primed reference numerals, an enlarged trash compacting member 54 is provided having a substantially flat bottom surface 56. Compacting member 54 is secured to a collar element 58, as by welding at 60. Bottom end 16 of handle member 12 is inserted in collar member 58 so as to engage inner portion 36' of compactor member 54 which thus serves as a seat for bottom end 48 of spring 46. Collar member 58 and compactor member 54 are secured to bottom end 16 of handle member 12 by suitable set screw 62. Inner portion 36' of compactor member 54 has center opening 40' therein through which pointed end 26 of rod element 28 extends in the extended position.
It will now be seen that the embodiment of FIG. 4, with the rod element 22 retracted as above described, can additionally be used for compacting trash deposited in a receptacle, such as a plastic trash bag.
While there have been described above the principles of this invention in connection with specific apparatus, it is to be clearly understood that this description is made only by way of example and not as a limitation to the scope of the invention.
