Description
BACKGROUND OF THE INVENTION
With the ever increasing adoption by urban dwellers of pets,
particularly dogs, the city sidewalks and limited park areas have
become so soiled as to become a hazard to pedestrians and to deny
the public enjoyment of the few outdoor relaxation facilities that
do exist. In an effort to counteract this situation, the civic
authorities have enacted ordinances requiring pet owners or
handlers to clean up after their pets or be subject to heavy fines,
so that the public areas should remain relatively clean.
To comply with the ordinances, the owners must carry cleaning
materials when walking their pets to clean up feces after it has
been dropped. Such materials usually comprise a quantity of tissues
or the like for cleaning purposes, and a disposable receptacle for
such tissues after use. This is a messy job, requiring bending and
stooping, and the handler may become soiled in the process. Various
devices or tools have been proposed to assist in the cleaning
process but leave much to be desired. Basically, these tools are in
the nature of a scoop for shoveling the feces, or tongs for
grasping the feces. Even if provided with disposable covers, these
tools are subject to becoming soiled in use and must be cleaned,
and, in any event, are not completely effective because they are
capable of removing only the major portion of the feces, the
balance being scraped over the surface.
SUMMARY OF THE INVENTION
A sanitary device according to the present invention comprises an
elongate wand, conveniently having the configuration of a walking
stick or cane, that is constituted by a body portion and a sleeve
telescopic thereon and normally covering one end of the body
portion. A pair of spring arms are fixed to the normally covered
end of the body portion to spring apart when they are freed by
retraction of the sleeve. A disposable receptable of flexible
material having sleeve portions along at least the opposite sides
of its open top is mounted by its sleeve portions on the spring
arms so that the top of the receptacle is spread open when the
sleeve is retracted and the arms spring apart.
In preparation for an outing, the handler retracts the sleeve,
squeezes the spring arms together, fits the sleeve portions of a
receptacle on the arms, wraps the receptacle around the arms, and
slides the sleeve outwardly to enclose the wrapped arms. When the
pet indicates that it is ready to perform its act of nature, the
handler retracts the sleeve to free the arms which spring apart to
open the receptacle for use. The handler holds the wand to dispose
the open topped receptacle beneath the pet to catch the feces as it
is dropped. The handler then slides the sleeve to collapse the
arms, carries it to a refuse container where he further extends the
sleeve to expel the receptacle. The feces has not touched the
ground surface or any permanent part of the device. According to a
modification the spring arms may be connected to an electric source
so that the device also can function as an electric prod as
protection against muggers and the like.

DETAILED DESCRIPTION OF THE INVENTION
Referring now in detail to the drawings, specifically to FIG. 1, a
sanitary device for pets according to the present invention
comprises a wand 10 including a body portion 12 and a sleeve 14
slidable on the lower end of the body portion. At its opposite end
the body portion 12 may be provided with a handle for convenience
in carrying and at its lower end the sleeve 14 may be provided with
a collar 18 simulating the foot of a walking stick so that the
overall general appearance of the device may be that of a cane. As
better shown in FIGS. 2 and 3, the body portion may be provided
with a stud 20 that extends through a bayonet slot 22 in the sleeve
to limit the telescopic movement of the latter, the slot having a
laterally extending branch at its upper end to secure the sleeve in
extended position until use of the device is necessary.
At its lower end the body portion is provided with a slot 24
extending axially thereof and within which are fitted the base ends
26 of a pair of spring arms 28, the arms being anchored in position
by a diametrically disposed rivet 30. As best shown in FIG. 3, the
arms normally tend to spring apart and include arcuate cam portions
32 adjacent their base ends with relatively straight main portions
terminating in angularly bent tip portions 34. Thus in normal
condition, prior to operation, the arms are compressed toward each
other and retained by the sleeve when the latter is extended.
In addition to the foregoing wand structure the device includes a
disposable receptacle 40, best shown in FIGS. 5 and 6. Conveniently
this receptacle may be formed of a moisture-proof material such as
pliofilm and may be a relatively flat envelope having portions of
its upper open end folded over and secured to provide sleeve
portions 42. The envelope may be formed of any suitable flexible
material but a plastic material is advantageous both because it is
moisture-proof and has greater tensile strength, but readily may be
formed into an envelope by heat sealing the edges and the free edge
of the sleeve portion.
In operation, the sleeve 14 is retracted on the body 12 to expose
the arms 28 whereupon the arm tips 34 are inserted into the open
ends 44 of the sleeve portions of a receptacle 40. When the
receptacle is fully mounted on the arms 28, the arms are compressed
toward each other and the envelope is wrapped around the arms
whereupon the sleeve 14 is extended outwardly to the limit imposed
by the slot 22 and stud 20 so that the arms and the receptacle are
fully enclosed within the sleeve, as shown in FIG. 2. The device is
then ready for the handler to take the pet for his airing and the
device has the overall appearance of a walking stick or cane so
that there is nothing unusual about its appearance.
When the pet gives indication that it wishes to relieve itself the
handler then twists the sleeve to unlock the bayonet slot 22 and
retracts the sleeve to enable the arms to spring apart and open the
receptacle as shown in FIG. 7. The handler then holds the wand with
the open topped bag immediately beneath the pet to receive feces as
it is discharged by the pet. When the pet has finished, the handler
then extends the sleeve outwardly so that the open end of the
sleeve engages the cam portions 32 and cams the arms toward each
other to close the open end of the receptacle. The handler then
proceeds to the nearest trash collection receptacle and further
extends the sleeve to expel the receptacle from the arms into the
collector and fully enclose the arms so that the complete operation
has been performed without the feces touching the ground surface of
any part of the device.
According to a modification shown in FIGS. 8-11, the device also
may serve as an electric prod as a defense against muggers and
other types of thieves who are so common in the urban areas. In
this event, the arms 28' may comprise rods which are mounted in an
insulated end portion of the body portion 12' and connected by
suitable conductors 48 with a power source 50 such as batteries
enclosed within the upper end of the body portion and which may be
retained by a screw cap 52 or the like. A switch 54 is included in
the circuit with the conductors 48 and power source 50, so that the
operator readily may manually control energization of the arms
28'.
In this instance the receptacle 40' must be of a non-conductive,
insulating material and it must have two separate sleeve portions
42 on opposite sides thereof to enable the arms to extend
completely through the sleeve portions of the receptacle with their
ends exposed beyond the receptacle. After the receptacle is
mounted, the arms then are urged toward each other and the
receptacle is wound around the major portions of the arms to
insulate them from each other. In the event that the handler is
approached by a mugger he immediately retracts the sleeve 14' to
expose the ends of the arms 28' and closes the switch 54 so that
the arms constitute electric prods that will serve to shock the
assailiant.
The modified structure shows variations in configuration that may
be employed. For example, the sleeve 14' may be provided with
interned lugs 22' that are slidable in longitudinally extending
slots 20' in the body portion 12' to limit telescopic movement of
the sleeve. In addition, the configuration of the arms per se may
be different in that the cam portions 32' may be relatively
straight rather than curved but in all respects the operation of
the arms by the sleeve is identical to that of the previously
described embodiment. Obviously, the arms, and preferably the cam
portions, can be of rigid material and attached by spring means to
the body portion.
