Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates generally to handheld mechanical devices. More particularly, the invention concerns a novel, handheld article grasping device that can be used to grasp articles having contaminated surfaces such as door handles and the like.
2. Discussion of the Prior Art
Research has established that various types of harmful bacteria can survive for long periods of time on the surfaces of articles such as door handles; gate handles; mailbox handles; toilet flush handles; paper towel dispenser handles; sink faucet handles; handles on trash receptacle lids and like surfaces which are continuously contacted and contaminated by large numbers of people. Surfaces, such as surfaces on door handles, particularly those located in public buildings, are infrequently cleaned thereby permitting a substantial build up on the surfaces of easily spread, harmful bacteria. Transfer of the harmful bacteria from the hand of the user to the nose and mouth or eyes can cause serious illness. Similarly, if one has a cut or abrasion on the hand that contacts the door handle through which the harmful bacteria can penetrate, serious repercussions can follow. It is this serious cross-contamination problem that the present invention seeks to mitigate by providing an easy to use, easy to transport, handheld apparatus that can be used to grip and operate articles having highly contaminated surfaces.

DESCRIPTION OF THE INVENTION

Referring to the drawings and particularly to FIGS. 1 through 5, one form of the article grasping apparatus of the present invention for grasping objects such as door handles and the like comprises a housing 14 having spaced-apart top and bottom structures 16 and 18 respectively and first and second side structures 20 and 22 respectively, which cooperate to define an internal chamber 14 a (FIG. 5). As best seen in FIGS. 3, 7 and 8, first side structure 20 includes an elongated chamber 24, the purpose of which will presently be described.
Connected to housing 14 for movement between a first stowed position shown in FIG. 6 and a second deployed position shown in FIG. 8 is a uniquely configured grasping member 26. As illustrated in FIG. 5 of the drawings, grasping member 26 includes an end or hub portion 28 disposed within internal chamber 14 a and an interconnected arm portion 30 that is receivable within elongated chamber 24 of the first side structure when grasping member is in the stowed configuration shown in FIG. 6. As indicated in the drawings, arm portion 30 terminates in a generally hook-shaped extremity 32.
Deployment means, the character of which will presently be described, is carried by housing 14 and functions to move the grasping member 26 from its stowed position to its deployed position. In the present form of the invention, this important deployment means comprises a torsion spring 34 (FIG. 5) that is carried by housing 14 in the manner indicated in FIG. 5 of the drawings. Torsion spring 34, which is of conventional construction, has a longitudinal axis 37, a first end 40 that is connected to bottom structure 18 and a second end 42 that is connected to a pushbutton 44 that forms a part of the operating means of the invention. The torsion spring 34 is constructed and arranged to turn second end 42 about longitudinal axis 37, while first end 40 is held fast by the bottom structure 18 of the housing 14.
The important operating means of the invention, which is carried by housing 14, functions to operate the deployment means of the invention in a manner to cause grasping member 26 to move from its stowed position to its deployed position. In the present form of the invention, the operating means comprises the previously identified pushbutton 44 to which the upper end 42 of the torsion spring 34 is connected. As indicated in FIGS. 6, 7 and 8 of the drawings, pushbutton 44 is slidably received within a central bore 46 formed in the end portion 28 of the grasping member 26 for movement against the urging of torsion spring 34 between a first position shown in FIG. 6A and a second position shown in FIGS. 7 and 7A.
As best seen in FIG. 7A, the central bore 46 of the end portion 28 includes a pair of semicircular-shaped, inwardly extending ring-like segments 46 a that cooperate to define a pair of oppositely disposed grooves 50 and 52. As indicated in FIGS. 5 and 6A, pushbutton 44 is provided with opposing, outwardly extending tongues 54 and 56 that are selectively, slidably received within opposing groves 50 and 52. More particularly, when the grasping member 26 is in its stowed position (FIG. 6) and when pushbutton 44 is in its upstanding position (FIG. 6A), tongue 54 is received within groove 50. However, when the grasping member is in its deployed position (FIG. 8), tongue 56 is received within groove 50 and tongue 54 is received within groove 52 thereby locking the grasping member in its deployed position.
Turning to FIG. 5, it is to be noted that bottom structure 18 of the housing includes an upstanding rim portion 58 and an upstanding spring locating member 60 over which the lower portion of torsion spring 34 is received. As best seen in FIGS. 5 and 7A, pushbutton 44 further includes a pair of opposing stop ears 62 and 64 which are constructed and arranged to engage the rim portion 58 of the bottom wall structure when pushbutton 44 is in the second, depressed position shown in FIG. 7A. Stop ears 62 and 64 function to control the downward movement of pushbutton 44 once the pushbutton is depressed in the manner shown in FIGS. 7 and 7A.
When the apparatus of the invention is not in use, the grasping member 26 is in the stowed position shown in FIG. 6 and the stop button 44 extends upwardly through an opening 16 a formed in top or cover structure 16. When the apparatus is in the configuration shown in FIG. 6 of the drawings, it is quite compact and can be easily carried in the users pocket or purse. When it becomes necessary to open the door, or to grasp some other contaminated object, the grasping member 26 can be easily deployed by simply pushing down on pushbutton 44 against the urging of torsion spring 34 in the manner indicated by the arrow in FIG. 6. As the pushbutton is moved into the position shown in FIGS. 7 and 7A, tongue 54 will clear groove 50 permitting the preloaded torsion spring 34, which is connected to the pushbutton, to rotate the grasping member initially into the position shown in FIG. 7 of the drawings and then into the fully deployed position shown in FIG. 8. Once the stop ears 62 and 64 are in engagement with upstanding rim portion 58, the user can release the downward forces exerted on the pushbutton thereby permitting the torsion spring to move the pushbutton upwardly into the position shown in FIGS. 8 and 8A. As the pushbutton moves toward its starting position, tongue 54 will move into groove 52 thereby locking the gripping member 26 in its deployed, extended position as shown in FIG. 8. In the present form of the invention, tongue 54, along with groove 52 comprises the locking means of the invention for releasably locking the gripping member 26 in its deployed position.
When the apparatus user has finished using the apparatus a downward force exerted on the pushbutton will permit the grasping member 26 to be manually returned to its stowed position against the urging of torsion spring 34. This movement of the grasping member into its stowed position will once again reload the torsion spring so that the deployment operation can be accomplished in the manner described in the preceding paragraph.
In order for the apparatus to be securely gripped by the user during operation, side structure 22 is provided with a longitudinally extending, yieldably deformable elastomer strip 65 (Figure one).
Having now described the invention in detail in accordance with the requirements of the patent statutes, those skilled in this art will have no difficulty in making changes and modifications in the individual parts or their relative assembly in order to meet specific requirements or conditions. Such changes and modifications may be made without departing from the scope and spirit of the invention, as set forth in the following claims.
