Description
Background of the Invention
1. Field of the Invention
The field of invention relates to retrieving tools, and more particularly pertains to a new and improved retrieving tool that selectively and readily enables interchangeable jaws to be utilized dependent on application desired.
2. Description of the Prior Art
The use of retrieving tools for remote pick-up of various items is well known in the prior art. Generally these items are directed to the retrieval of a single class of debris and the like and are not subject to a ready interchange of jaws.
For example, U.S. Pat. No. 3,910,619 to Schmieler wherein a pick-up scooper utilizes an illumination device proximate the handgrip portion of the tool to illuminate the scoop and closure lid that may be manipulated by the supporting hand of the user. Propelling means are provided in the receptacle and the operatable manually propellent material scooped into the entry of the receptacle. Essentially the device is ostensibly intended to be used during periods of dim light.
U.S. Pat. No. 4,005,892 to Williams sets forth a cane-like retrieving tool wherein debris is received within a fixed scoop positioned proximate a lowermost portion of the cane with the addition of a pivotal lid cooperating with the scoop.
U.S. Pat. No. 4,042,269 to Skermetta sets forth a scoop for use as a portable toilet for pets wherein a container is mounted relative to an elongate pole and wherein a pivoted flap overlies the container for selective containment of debris therein and further including a pivotal bottom of the container to assist in depositing debris accepted within the container.
U.S. Pat. No. 4,299,419 to Kalan sets forth a fireplace ash cleaning shovel wherein a lowermost scoop utilizes a pivoted closure lid manipulatable at a remote position from the lid to accept ash from a fireplace therewithin.
U.S. Pat. No. 4,316,627 to Solypa sets forth a manure collection device for use with household pets and the like wherein a bottom scoop utilizes a tined arrangement for accepting manure to be deposited within the container with a pivoted lid for secure containment of the manure deposited to enable remote disposal of the manure.
As such, it may be appreciated that there is a continuing need for a new and improved retrieval tool that utilizes easily replaceable jaw sets for adapting the tool to the retrieval of debris and the like of various configurations and in this regard, the present invention substantially fulfills this need.

Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIG. 1 thereof, a new and improved retrieval tool embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
More specifically, the retrieval tool of the instant invention essentially comprises an elongate conduit vertically disposed terminating an uppermost portion with a downwardly directed handle 12 angulated at an acute angle relative to the body 11 and terminating in a padded covering 13 for grasping by a user. Pivotally spaced from the handle 12 is an actuation handle 14 pivotally secured to a bracket 15. The actuation handle has secured thereto the forward end of a flexible cable 19 slidably mounted within a sheath 20 fixedly secured relative to the housing 11.
A lowermost terminal end of the body 11 is threadedly mounted within a threaded socket 17 formed within an upwardly directed cylindrical boss 18. The boss 18 integrally formed to an underlying housing 21.
A lowermost terminal end of the flexible cable 19 is secured to an actuation pin 22 that is directed orthogonally outwardly of an upper pivotal receiving jaw 25 pivotally mounted to the housing 21 within a cavity 23 formed within the housing 21 by means of an elongate pivot connection 26. A lower fixed receiving jaw 24 is integrally formed to the housing 21 and projects forwardly thereof to cooperate with the upper pivotal receiving jaw 25. The receiving jaws 24 and 25 are arranged to receive a jaw set 27, as illustrated in FIG. 3 for example.
The jaw set 27 includes an upper pivoted grasping jaw 28 resiliently mounted to a lower fixed grasping jaw 29 by means of a coextensive "C" spring 30 transversely aligned relative to the upper and lower grasping jaws 28 and 29 and are secure thereto by means of conventional rivets 31 or the like. The "C" spring 30 is secured within respective arcuate recesses formed in the upper and lower grasping jaws.
The lower grasping jaw 29 is formed with a rearwardly directed extension 32 extending rearwardly of the grasping jaw 29 and of a length to exceeded the length of the lower fixed jaw 24 and associate housing 21 such that the extension 32 is directed rearwardly through a complementary opening 33a. The extension 32 is formed with an elongate slot 33b for accepting an "L" shaped securement plate 33 therethrough. The securement plate 33 is normally positioned within a housing bracket 34 and integrally formed to a rear face of the housing 21 whereupon lifting of the securement plate 33 relative to the bracket 34, the lower grasping jaw 29 may be slit rearwardly and upon directing the securement plate again downwardly, it will engage the jaw extension 32 through the associated slot 33b.
Since the jaw set 27 comprising the upper and lower grasping jaws 28 and 29 are secured together by means of the elongate "C" spring 30, the jaw set 27 will remain in operative position, as illustrated in FIG. 3, and upon grasping of the actuation handle 14, the lower terminal end of the flexible cable 19 will draw the associated actuation pin 22 upwardly and thereby close the jaw set 27 of the tool 20.
The FIGS. 5a and 5b set forth a first example of a series of jaw sets that may be utilized by the instant invention. The upper grasping jaw 28a is formed with an serrated arcuate recess complementarily coacting with lower serrated arcuate recess 36a for the grasping of aluminum cans and the like. The jaw set represented in FIGS. 6a, 6b, and 6c utilize a downwardly directed plate 37 integrally formed to the upper grasping jaw 28b cooperating with an enlarged projection 38 orthogonally formed to the lower grasping jaw 29b wherein the downwardly directed plate overlaps the enlarged projection 38 upon closure of the grasping jaws 28b and 29b for securement of flexible debris, such as paper, therebetween.
The third jaw set illustrating jaws 28c and 29c employ a series of cooperating upper and lower magnets 40 and 41 for the collection of metallic debris, such as nails, wire and the like. The fourth jaw set illustrated in FIGS. 8a, 8b, and 8c utilize a lower fixed grasping jaw 29d formed with a series of projecting tines with an overlapping upper pivotal grasping jaw 28c formed with a cavity 41 to secure weeds and the like therebetween.
As to the manner of usage and operation of the instant invention, the same should be apparent from the above description and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be set forth.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
