## Background
FIELD OF THE INVENTION
The present invention relates to a pet animal utensil, particularly to a device for pet animal droppings collection, more particularly to a device for pet dog droppings collection.
BACKGROUND OF THE INVENTION
Presently, there is an increasing number of domestic pet animals with years. People are fond of carrying pet animals going for a stroll. However, the accompanying problem is that the pet animals leave over their droppings in public spaces such as streets, gardens, and lawns. Pet animals relieve or discharge themselves everywhere not only causing serious environmental sanitation problem, but also badly affecting people who walk around if the droppings are not timely removed out.
For environmental sanitation sake, pet animal raisers have the responsibility to timely remove their pet animal droppings. Currently, the primary method for collecting pet animal droppings is placing waste paper or plastic bag by hands underneath a pet animal, then wrapping the droppings and throwing into a garbage can. Handling pet animal droppings in such a way is both not good for hygiene and inconvenient.
Japan Patent JP2000333584 discloses a handling means for dog excreta. Operating such handling means comprises pulling up and down a web. The primary shortcomings are inconvenient in operation and not good-looking.
Japan Patent JP9224518 teaches another kind of means for dog droppings collection. The problems of this kind of means are that the distance between the point of support and the point of action in the open-close mechanism is too small, leading to an uneasy open-close operation for the open-close mechanism and that the loading arm is movable, so that the plastic bag opening not always is able to be normally opened.
U.S. Pat. No. 4,878,703 discloses a means for pet animal droppings handling. Said means needs additional executing mechanism for automatically opening-closing a droppings collection bag. Therefore, it is relatively complicated in both of its construction and mechanical design.
U.S. Pat. No. 4,225,169 relates to another kind of means for pet animal droppings collection. Said means comprises an umbrella-like manipulator. When it is required to collect droppings, which fell onto ground by pet animals, the manipulator in the closing state is encased with a collection bag, then the manipulator is opened to pick up the droppings and put them directly in the collection bag, which has already been encased on the manipulator. Such a design allows the avoidance of handling the droppings directly by hands, but the pet animal droppings have already dirtied the public places.
Although the droppings collection means disclosed in the above-mentioned patents have performed their individual goals, they still have the problems of complicated structure and uneasy operation, or they are merely used for collecting the excreta, which are already on ground with the disadvantage of environmental sanitation. Therefore, there is a need to provide to pet animal raisers a more convenient and more hygienic device for pet animal droppings collection.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1 and FIG. 2, there is shown a device for pet animal droppings collection of the present invention as a preferred embodiment, comprising a long and thin hollow pole 3 which is connected at its upper end with a handle 1 and at its lower end with a fixing panel 9, and in which a metal lever 6 is placed. There is a curve portion 7 of about 130° at a connection site of the handle 1 with the hollow pole 3, on which is provided a hole in communication with the hollow portion of hollow pole 3, as shown in FIG. 4. Said metal lever 6 passes through said hole and has its upper end extending out to connect with a button 2, its lower end extending out to connect with an operating mechanism 4. FIG. 3 shows a perspective view, which illustrates a droppings collection bag 5 mounted onto said operating mechanism 4. The hollow pole 3 has a length in the range of about 0.6 m to 0.9 m, allowing the user to place the droppings collection bag 5 at the rear of the pet animal without bending his/her body.
As shown in FIG. 4, a curve portion 7 is arranged on the connection site of the handle 1 and the hollow pole 3 with a curvature of about 130°, which facilitates the user to stand by the pet animal holding said collection device. When said handle 1 is held in hand, the button 2 at the upper end of the metal lever 6 is under control by fingers of the user who may push down the button 2 to open the droppings collection bag 5 to let the pet animal eject its droppings directly into the collection bag 5.
FIG. 5 shows the connection relationship between the operating mechanism 4 and the metal lever 6 of said device for pet animal droppings collection. It can be clearly seen that said operating mechanism 4 is composed of a movable assembly 10 and a collection bag supporting assembly 11, the metal lever 6 extends out of the hollow pole 3 to connect to the movable assembly 10 mounted on the fixing panel 9. Thus, through said fixing panel 9, said operating mechanism 4 is fixed on the lower end of the hollow pole 3, between which end and said operating mechanism 4 a spring 8 is cross-connected. Under the action of said spring 8, said operating mechanism 4 is kept in a closing state. When the spring 8 is forced, said operating mechanism 4 is driven to be opened.
Now referring to FIG. 6 to FIG. 9, they are, respectively, the front-views and the rear-views of said operating mechanism 4 in the opening state and in the closing state. It can be seen from these views that there is provided a slot 14 in the middle or the central position of the fixing panel 9, which guides the metal lever 6 to move up and down upon opening and closing said operating mechanism. As above-mentioned, said operating mechanism 4 is composed of the movable assembly 10 and the collection bag supporting assembly 11.
Said movable assembly 10 comprises a pair of L-shaped actively movable parts 13 and a pair of I-shaped follow-up movable parts 12. Said two pairs of the movable parts 12 and 13 are, respectively, fixed on said fixing panel 9 in a rotatable way, while one end of said L-shaped actively movable parts 13 is connected with said metal lever 6 in a rotatable way. Preferably, said one pair of I-shaped follow-up movable parts 12 comprises individually two metal panels, said two metal panels are, respectively, secured to both sides of said fixing panel 9 at the same position to increase the strength of the operating mechanism 4.
Said collection bag supporting assembly 11 is comprised of one pair of symmetrically arranged L-shaped supporting parts 17 and 18, wherein two long end portions of said L-shaped supporting parts 17 and 18 are used for mounting the collection bag, said parts 17 and 18 being kept closely together when the pet animal droppings collection device is in closing state, while two short end portions are rotatably connected with two pairs of the movable parts 12 and 13, respectively, and take an arc movement with said two pairs movable parts 12 and 13. Said L-shaped supporting parts 17 and 18 make an angle of about 120° with said hollow pole to allow the user to easily stand by the pet animal placing the droppings collection bag 5 at the rear of the pet animal. In order to easily mount and dismount the droppings collection bag 5, the oppositely arranged ends of the long end portions of L-shaped supporting parts 17 and 18 are fork-shaped.
As one end of said movable assembly 10 is fixed on the fixing panel 9 and the other end is connected to the collection bag supporting assembly 11, on each side of the metal lever 6 there forms a parallelogram 16. By controlling the button 2, the metal lever 6 is moved up and down so as to drive the two parallelograms 16 to open or close, thereby the droppings collection bag 5 can be easily mounted and dismounted and its bag opening can be easily opened.
FIG. 10 shows a droppings collection bag 5 employed by the present invention, which may be made of plastic materials or degradable materials for disposable use.
There is a hollow cavity 19 on the opposite two sides of the bag opening respectively, said L-shaped supporting parts 17 and 18 are inserted in via an entry 20 of said hollow cavity 19, making the collection bag 5 to be firmly mounted on the operating mechanism 4. In order to more easily mount the droppings collection bag 5, a tough or hard inner lining may be placed in the hollow cavity 19 of said collection bag 5. In addition, there is a rope 21 around the bag opening of the droppings collection bag 5, which in one hand is used for fixing said collection bag 5, and in the other hand, is used for tying the bag opening after pet animal droppings are collected, and then the bag 5 is thrown into a garbage can or box.
When not in use, under the tension action of the spring 8 set between the lower end of the hollow pole 3 and the operating mechanism 4, the operating mechanism 4 is closed up, the pet animal droppings collection device of the present invention is returned to its closing state (shown in FIG. 1), making it easy to carry about.
When the user finds his/her pet animal has a call of nature, he/she just simply mounts the droppings collection bag 5 carried with the user via its entry 20 of the bag opening onto the two L-shaped supporting parts 17 and 18 of the operating mechanism 4. The user then holds the handle 1 and slightly pushes down the button 2 to make the metal lever 6 placed inside the hollow pole 3 to move downward along the slot 14 of the fixing panel 9. Such a downward movement of the metal lever 6 allows the movable assembly 10 to force the spring 8 to drive the movable assembly 10 which, in turn, drives the collection bag supporting assembly 11 to move in opposite direction to thereby open up the droppings collection bag 5. At this point, the user can place the droppings collection bag 5 at the rear of the pet animal to receive the droppings ejected by the pet animal. After that, the user moves his/her fingers away from the button 2 to let the spring 8 restore and draw back the movable assembly 10, which makes the collection bag supporting assembly 11 closing up, followed by the closing up of the droppings collection bag 5. Finally, the user can dismount the droppings collection bag 5, tie up the bag opening with the rope 21, and discard the bag into a garbage can.
The device for pet animal droppings collection of the present invention is very handy, easy to operate. It is unfolded when in use, while it is folded when not in use. Therefore, it is convenient to carry about. In addition, the collection device according to the invention has a simple design in the mechanical movement and the mechanical power, without the need of any additional or complex mechanism, which therefore reduces the production cost.
Although the present invention has been illustrated by one preferred embodiment in combination of the drawings, it is understood for the skilled artisans of the art that a number of modifications and variations can be made without going beyond the spirit and scope, for example, the operating mechanism of the pet animal droppings collection device can take other shapes, all these modifications and variations are within the protective scope which are claimed by the present invention.
