Abstract
Disclosed is a scissor-like waste disposal device having handles
at one end and blades at the other end. The blades have upstanding
side walls which form a receptacle for waste upon assuming a closed
position. One blade has a finger extending across the engaging
blades to prevent waste between the blades from moving out of
engagement. A plastic bag is provided secured to the pivot of the
scissor and arranged to act as a shield in a first position and, in
a second position, to be pulled over and secure therewithin the
waste and the blades. To this end a twist wire is affixed within
the marginal end of the bag at its opening.

Description
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 becoming the 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 and personal 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 U.S. 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.
Still another device is proposed by Johnston in U.S. 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 to one 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 one's home or place of business.
Even where it is not inconvenient to carry a waste removing device,
all of these devices provide certain disadvantages 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 manipulation to retrieve
waste. Furthermore, the narrow engaging surfaces of the jaws and
the sharply curving walls thereof, will cause, it is believed, the
refuse to 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.
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.

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 forming 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. The 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.
In 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 enclosing therewithin 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 three-sided 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 18 with the finger 28, 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 dog's 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.
It 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.
