10 Claims, 4 Drawing Figures ARTICLE COLLECTING DEVICE BACKGROUND OF THE INVENTION This invention relates to devices for picking up articles and more particularly to devices intended to engage and collect such articles as, for example, refuse of various types.
. More and more refuse and trash are becomingthe pressing problem of society. In particular, it is noted that there are an increasing number of government laws, ordinances, and regulations directed to individuals to properly-dispose of trash. In this connection, government agencies are requiring individuals to dispose of refuse caused by their industry andpersonal activities, including excrement left by pets.
Various suggestions have been made to provide implements capable of picking up trash, refuse, the excrement of animals, and the like. One such device is proposed by Fisher in U.S. Pat. No. 3,281,178. This device provides a frame as an integral part of an elongated handle. The frame supports a plastic bag which may be removed when desired, for disposal.
Another suggested device is a pair of pivotally mounted tongs carrying thereon a tissue container. This device, proposed by Gruber in US. Pat. No. 3,560,039, is intended to dispose of animal excrement by means of first engaging the excrement in the tongs and then removing it from the tongs by means of the tissues secured at the pivot. a
Still another device is proposed by Johnston in US. Pat. No. 3,328,066. Johnston proposes an elongated handle With tongs, not unlike those of Gruber. The tongs are integral with lever arms which are, in turn, pivotally secured toone another. The jaws of the tongs,
suggested by Johnston, are provided with lateral coplanar plates which, upon closing, form a pocket to hold trash therewithin.
All of these devices have a number of disadvantages. They have in common a bulkiness which makes them cumbersome to carry about and use. In addition, the construction of these devices is so intricate as to make it uneconomical to dispose of immediately after a single use. Bulkiness aside, there is the problem of carrying an instrument which is filthy from the trash or excrement it has collected, back to ones home or place of business.
Even where it is not inconvenient to carry a waste removing device, all of these devices provide certain dis; advantages in the manner in which the refuse is picked up. In devices of the type proposed by Fisher, for example, refuse and particularly moist and semi-fluid excrement is pushed ahead of the open-mouthed receptacle. Unless another implement is used, at least a substantial part of the waste is likely to remain unremoved. The
devices of the type proposed by Gruber and Johnston are similarly inefficient. Waste, and in particular animal excrement, rarely conforms to such a shape as to permit closing jaws to conveniently and cleanly grasp and retain such matter. More than that, there is believed to be required a considerable amount of dexterity and manipulationto retrieve waste. Furthermore, the narrow engaging'surfaces of the jaws and the sharply curving'walls thereof, will cause, it is believed, the refuset'o be pushed outwardly as the jaws close. This is particularly true where such waste is powdery or dust-like.
In general, closing jaws or tongs are inefficient in holding portions of most particles. Thus, there is not provided in the aforementioned devices a sanitary method of waste removal. Gruber suggests the use of tissues. However, Gruber suggests the use of tissues provided in a container. In such a setting, the device must first gather the waste and then a separate tissue must be removed and placed about the waste. This is believed to be highly cumbersome and inconvenient. First, the waste must be removed and grasped by the tissue. Contact with waste cannot be avoided. Second, in such movement, the dropping of waste cannot be avoided. Furthermore, none of the devices discussed herein provide any means for shielding the hands of the user, particularly where the device requires that the hands be placed near the waste.
SUMMARY OF THE INVENTION It is an object of this invention to provide a waste collecting device which is economical to manufacture, and convenient to use.
It is an object of this invention to provide a waste collecting-device which may be, if desired, disposable.
It is still another object of this invention to provide a sanitary method of removing such waste as, for example, animal excrement.
It is still another object of this invention to provide means for protecting the hands of the user from the waste and means for enclosing and disposing of the waste. 7
In fulfillment of these objectives there is provided a device for removing waste or refuse. Generally, this device is a pair of pivotally mounted lever arms. Means are provided, at one end of the lever arms, to collect the waste or refuse. A bag 'or receptacle is provided secured at its closed end and proximate the pivot point of the lever arms. The bag is so arranged that it may be disposed about and enclose therewithin the collecting means.
In another aspect of this invention, there is provided a scissor like device having handle and blade portions.
The blade portions have substantially lateral walls. Upon closing the blades upon, for example, waste, the blades overlap and the lateral walls form, in combination with said blades, a receptacle.
BRIEF DESCRIPTION OF THE DRAWING DESCRIPTION OF THE PREFERRED EMBODIMENT Disclosed is a device 10 for picking up articles such as, for example, waste and the like. One such use may be, as has been previously indicated herein, to remove animal excrement.
The device 10 comprises two scissor arms 12 and 14 which includes handle portions 16 and blade portions 18 and 20. The two scissor arms 12 and 14 may be pivotally secured to one another by any well-known means, such as a pin 22 located between the handle portions 16 and the blades 18 and 20. The blades 18 and 20 may be substantially planar members with the perimeters thereof defining rectangles. The rectangular blades 18 and 20 may be arranged with the large dimensions fonning the engaging edges 24 and 26 thereof.
One of the blades 18 may have a finger 28 extending laterally with respect to the rectangular shape thereof and across the engaging edges 24 and 26 of both blades 18 and 20. The finger 28 may have a surface coplanar with the surface of the remainder of the blade 18 and form a rectangular extension thereof with at least one edge coincident with one edge of the blade 18.
The blades 18 and 20 overlap at their respective engaging edges 24 and 26. The opposed edges of each blade 18 and 20 may have substantially laterally upstanding side walls 30 and 32. The front of each blade 18 and 20, opposite the handle portions 16, may also have substantially laterally upstanding side walls 34 and 36. The engaging edges 24 and 26 of the blades 18 and 20 may be beveled with the apices 38 thereof being located adjacent the bottom surfaces of the blades 18 and 20. The application of the apices 38 will be more fully discussed hereinbelow.
Secured to the scissor arms 12 and 14 by the pin 22 may be a bag 40. The bag 40 may be secured at a closed end 42 which is opposite an open end 44 thereof. The marginal edge 44 defining the opening of the bag 40 may have a flexible semi-rigid member 46 therein. The member 46 may be made of any well-known material, such as a wire of metal or plastic.
The scissor arms 12 and 14 may be made of any commonly known material suitable for the purpose set forth herein. Thus, such materials as a semi-rigid or rigid plastic may be useful. Preferrably, the scissor arms 12 and 14 may be made of a thin and flexible plastic of approximately one eighth of an inch in thickness. The side walls 30, 32, 34, and 36 may extend upwardly, with respect to the blades 18 and 20, to a height of approximately 1 or 2 inches. .T he rectangularly shaped blades 18 and 20 may be, for example, approximately 3 by 6 inches. The swivel pin 22 may be made of metal or plastic, such as for example, a simple copper cotter pin. The bag 40 may be made of any well-known material, such as a transparent polyethelyne.
ln assembly, the two scissor arms 12 and 14 may be arranged for securing one to the other. The closed end 42 of the bag 40 may be open at this time and placed with the opposed sides of the bag 48 and 50 on opposed arms 12 and 14. The bag 40 may be arranged with the body thereof drawn over the blades 18 and 20. The pin 22 may then be inserted through the bag 40 and arms 12 and 14 (FIG. 2) and the end 42 of the bag 40 sealed shut thereabout by well-known means, such as heat or the like. Thereafter, the bag 40 may be drawn across and enclosingtherewithin the handle portions 16.
The blades 18 and 20 are so dimensioned as to form two scraping arms. When closed, the walls 30, 32, 34, and 36 together with the blades 18 and 20 form a threesided receptacle (FIG. 3). The blades 18 and 20 may be arranged so that either one is below the other and the front walls 34 and 36 close tightly upon one another (FIG. 3 Preferrably, the blade is with the finger 2s, 6
may be placed beneath the other blade 20 and the front wall 30 thereof disposed in front of the blade 20.
The plastic construction suggested herein provides for an easily disposable waste collecting device. In use, a hand 52 may be inserted into the bag 40 and engage the handle portions 16. The bag 40 acts as a shield to protect the hand 52 from any waste to be collected. Waste 54, such as the excrement of an animal, may be gathered in the device 10 by placing the blades 18 and 20 flat on the ground 56. As the blades 18 and 20 are closed, the excrement 54 may be expected to be moved toward the front end of the arms 12 and 14. This movement is the natural result of the action of the engaging edges 24 and 26 of the blades 18 and 20. The overlapping of the blades 18 and 20 will, to some degree, retain the waste 54 thereon. The finger 28, however, blocks the movement of the excrement 54 from proceeding outside the confines of the device 10. The apices 38 of the beveled edges 24 and 26 aid in the scraping action against the ground 56 necessary to remove a moist waste 54.
Upon completion of this activity, the bag 40 may be drawn or disposed about the blades 18 and 20 and the wire 46 twisted shut, sealing the excrement 54 therewithin. The entire assembly may then be conveniently disposed of in any garbage can, sewer, or the like.
The benefits of a device 10 of this type are immediately apparent. For example, a person walking a dog can conveniently carry this light device 10, remove the dogs excrement and dispose of it with the device 10 and not have to carry any part back to his residence.
Another example of the usefulness of this device 10 is in the picking up of loose and small particles of waste. The scissor action tends to gather these particularly hard to remove particles.
The shape of the blades 18 and 20 need not, of course, be rectangular. Any desired shape, including semi-circular or elipsoid, may be used. The upstanding walls may thus conform to the shape of the marginal edges. The walls, however, need not be placed at the marginal edges and may assume any desire configuration. If desired, a fourth wall may be provided on the disclosed device 10 across at least a portion of the blades adjacent the pivot pin 22.
lt is also clear that the bag 40 may be secured to any scissor or lever type device and so dimensioned that it may be disposed over the jaws or blades thereof.
