[0001] Pet transport and waste removal equipment. Background Art

[0002] There have always been several contradictions between dog owners in cities and ordinary citizens: 1) The danger of dogs attacking people around them in public places (elevators, lobbies, shopping malls, restaurants, offices, etc.) and health concerns; 2) The pollution of the environment caused by dogs' excretion in public places (buildings, streets, parks, etc.); 3) The need for short-term custody of dogs in public places. Many solutions have been proposed for these problems, such as the solutions with application numbers 202320964356, 202222380015, 201811139148, and 202022362165 are to solve the problem of picking up dog feces; the solutions with application numbers 201911027168 and 201520716834 are about how to prevent dogs from attacking people. At present, no existing solutions have been found to solve the above three problems at the same time. These solutions all have major defects, and they cannot fundamentally eliminate the adverse effects of dogs on citizens from the entire process of dogs from home to public places. For example, if people and dogs ride together in an elevator, the smell of the dog in the narrow space is unbearable. In addition, there is currently no good solution for dog feces on the grass in the park. We can only hope that the sanitation workers will find it and be willing to clean it up the next day. This wish is often not realized. Even if it can be realized, many citizens have already stepped on it before that. What's worse, some dog owners with low moral standards let their dogs defecate in the corridor, and the dog owners walk away without doing anything. For the consequences caused by the fault of the dog owner, bystanders or managers are often powerless and can only let it go. Therefore, quite a number of citizens currently have great opinions on dog keeping and hope that the city will ban dog keeping. However, dog keeping is a psychological need of some people in modern society, and the government cannot legislate to prohibit it.

[0003] In view of this, I invented a device that can better solve the above problems. Summary of the invention

[0004] In the following descriptions, "civilized dog walking cart" is sometimes referred to as "dog walking cart" or "cart". The three names refer to the same thing.

[0005] The civilized dog-walking cart comprises a body system 1, a linkage picking-up system 2, an animal box system 3, a telescopic handle system 4, a telescopic rear wheel system 5, and a warning sign 6.

[0006] The linkage picking system 2 is located inside and on the body system 1. After the animal defecates in a public place, the dog walker can place the two front wheels of the dog walking cart on both sides of the excrement and pick up the excrement into the plastic bag of the cart through the linkage picking system 2. This method is more civilized than picking up with bare hands, and dog walkers are more willing to accept it.

[0007] When the dog needs to be sent to the square or park downstairs, the dog can be put into the animal box system 3 on the dog-walking trolley, and then the trolley and the dog can be pulled to the elevator. The trolley enters the elevator, and the telescopic handle system 4 shrinks to the minimum state. The trolley and other citizens coexist peacefully in the elevator without conflict. When the dog arrives at the dog-walking location, the box door 32 is opened to let the dog come out and move freely. If the dog excretes during the period, the linkage picking system 2 on the trolley is used to collect the excrement in the trolley. At the end of the dog walk, let the dog enter the animal box system 3, pull it to the elevator, and pull it back home. There is no conflict or unpleasantness between the dog and the citizens, and the dog and public facilities during the whole process. If the dog wants to enter a public place such as a shopping mall, a restaurant, or an office building, the trolley can be placed in a special area in the lobby downstairs, and the dog or pet can be left in the animal box system 3. When the owner comes back, the trolley can be pulled away. During this period, the dog or pet will not conflict with citizens or factory facilities.

[0008] When returning home, the animal box system 3 is separated from the vehicle body system 1, and the plastic bag (not shown) on the receiving box 212 is taken out together with the dog's excrement for other treatment.

[0009] The animal box system 3 is a box that can accommodate animals. It can be integrated with the vehicle body system 1 to allow the dog-walking cart to perform the function of animal transportation, and can also be separated from the vehicle body system 1 to perform operations such as excrement cleaning or storage carts.

[0010] In order to facilitate pushing and pulling the trolley, the present invention also designs a telescopic handle system 4. The telescopic handle system 4 can adjust the extension length and the height from the ground to suit people of different heights to move the trolley comfortably. When the telescopic handle system 4 is retracted to the minimum, the entire trolley can be placed in the animal box system 3 to reduce the storage area.

[0011] The dog-walking cart is also designed with a retractable rear wheel system 5. When the animal box system 3 needs to be placed on the body system 1, the retractable rear wheel system 5 can be extended to both sides to increase the stability of the dog-walking cart; when the animal box system does not need to be placed on the body system 1, the retractable rear wheel system 5 can be retracted inward to a minimum to reduce the footprint.

[0012] This scheme also designs warning signs 6 for dog walkers to carry. When the dog walker does not carry a dog-walking cart and his dog excretes in a public place, the dog walker can take out warning signs 6 and place them on both sides of the excrement to remind passers-by not to step on the excrement.

[0013] Municipal management departments can encourage dog walkers to buy dog ​​walking carts and carry them when walking their dogs. They can also provide a certain number of carts in public places for dog walkers to use. At the same time, they can also encourage citizens to use nearby carts to clean up animal excrement when they find animal excrement in public places, thus forming a civilized and harmonious natural and social environment.

DETAILED DESCRIPTION

[0016] like Figure 3 and Fig.13 The civilized dog-walking cart comprises a body system 1, a linkage picking system 2, an animal box system 3, a telescopic handle system 4, a telescopic rear wheel system 5, and a warning sign 6. The body system 1 comprises a carriage 11 and a front wheel 12; the carriage 11 comprises a transverse carriage 111 and a longitudinal carriage 112; the linkage picking system 2 comprises a transverse unit 21, a longitudinal unit 22, and a picking unit 23; the transverse unit 21 is located in the transverse carriage 111, and the longitudinal unit 22 and the picking unit 23 are located in and above the longitudinal carriage 112; the transverse unit 21 comprises a guide rod 211, a receiving box 212, and a transverse rope 213; the longitudinal unit 22 comprises a longitudinal frame 221, a longitudinal rope 222, a public pulley 223; the up and down movement of the longitudinal moving frame 221 pulls the longitudinal moving rope 222 to move in the vertical direction, and the vertical movement of the longitudinal moving rope 222 drives the common pulley 223 to rotate, and the rotation of the common pulley 223 drives the lateral movement of the transverse moving rope 213, and the lateral movement of the transverse moving rope 213 drives the receiving box 212 to move left and right along the guide rod 211, thereby realizing the linkage between the longitudinal moving frame 221 and the receiving box 212; the picking unit 23 includes a handle 231, a pull rod 232, The connecting arm 233, the grab bucket 234, and the spring 235; the handle 231 is fixedly connected to the pull rod 232; the pull rod 232 is slidably located in the middle tube 2212 of the longitudinal moving frame 221, and the longitudinal moving frame 221 drives the entire picking unit 23 to move together; after the two front wheels 12 straddle the animal excrement on the ground, the longitudinal moving frame 221 moves downward to a low position, and the receiving box 212 moves to the left end of the transverse moving compartment 111 in a linked manner; at this time, the operator pinches the handle 231 and the longitudinal moving frame 2 The upper transverse tube 2211 of 21 allows the two grab buckets 234 to close, thereby picking up animal excrement from the ground; the longitudinal moving frame 221 rises to a high position, and the receiving box 212 moves to the right end and directly below the grab bucket; the operator removes the pinching force between the handle 231 and the upper transverse tube 2211, and the spring 235 pushes the pull rod 232 to move downward a short distance, thereby forcing the two grab buckets 234 to open, and the fallen excrement is caught by the receiving box 212 directly below, thereby completing the cleaning of animal excrement in public places.

[0017] Furthermore, the longitudinal movement unit 22 also includes a frame lock 225. Fig.13The frame lock 225 includes a lock plate 2251 and a lock bolt 2252; the lock bolt 2252 can be extended or retracted relative to the lock plate 2251, thereby controlling the longitudinal movement unit 22 to move freely up and down or be locked at a desired height.

[0018] Furthermore, the civilized dog walking car also includes an animal box system 3. Fig.21 The animal box system 3 includes a box body 31, a box door 32, a locking rod 33, a hinge 34, a bottom buckle piece 35, and a side clamp rod 36; the vehicle body system 1 also includes an upper buckle hole 14 and a side clamp ring 15; put the animal box system 3 on the trolley, tilt the box body 31 to allow the two bottom buckle pieces 35 to be buckled into the two upper buckle holes 14, and then press the box body 31 downward by hand, and the two side clamp rods 31 will be buckled into the two side clamp rings 15, thereby fixing the entire animal box system 3 on the vehicle body system 1, so that the animal box system 3 is firmly connected to the vehicle body system 1, so that animals can be conveniently stored or transported in public places.

[0019] Furthermore, the civilized dog walking cart also includes a telescopic handle system 4. Fig.17 The telescopic handle system 4 comprises a guide slot unit 41, a left fork arm 42, a middle fork arm 43, a right fork arm 44, a left mounting rod 45, a middle distance rod 46, and a handle 47; the left fork arm 42, the middle fork arm 43, and the right fork arm 44 are respectively connected end to end to be pivotally connected to form a telescopic structure; the left fork arm 42 further comprises an upper short arm 421, a lower long arm 422, an upper fixed head 423, and a lower movable head 424; the guide slot unit 41 comprises a bottom plate 411, a guide slot 412, and a locking bolt 413; the upper fixed head 423 is connected to the ... The left mounting rod 45 is pivotally connected; the locking bolt 413 passes through the lower movable head 424 and the guide groove 412 respectively; when the handle 47 is pulled to the right, the telescopic handle system 4 extends to the right, and at the same time, the lower movable head 424 and the locking bolt 413 slide upward along the guide groove 412, and tightening the locking bolt 413 can lock the telescopic handle system 4 in the extended state, and the trolley can be pulled to move; the reverse operation can lock the telescopic handle system 4 in the retracted state to facilitate the storage of the trolley.

[0020] Furthermore, the upper short arm 421 of the telescopic handle system 4 is shorter than the lower long arm 422, and the guide groove plate 41 is installed on the carriage 11 at an angle. This design allows the handle 47 of the telescopic handle system 4 to change height when extended, so that people of all heights can find a suitable handle height to comfortably pull the trolley. When retracted, the overall volume can become smaller to facilitate storage of the trolley.

[0021] Furthermore, the civilized dog walking car also includes a telescopic rear wheel system 5. Fig.18The telescopic rear wheel system 5 comprises two half-insertion frames 51, a middle gear 52, and a rear wheel 53; the half-insertion frame 51 comprises a thick tube 511, a thin tube 512, a connecting plate 513, and a rack 514; the rack 514 is located on the inner surface of the thick tube 511; during installation, the two half-insertion frames 51 are reversed and inserted so that the two thin tubes 512 are respectively inserted into the two thick tubes 511; the middle gear 52 is located on the front and rear central axis planes of the vehicle body system 1 and is also located at the center of the square frame surrounded by the two half-insertion frames 51; the size of the middle gear 52 can reliably drive the racks 514 on both sides to move in the opposite direction, so that the two rear wheels 53 can move away from or close to each other with the front and rear central axis planes of the vehicle body system 1 as the symmetry plane to increase the stability of the trolley when in use or reduce the volume of the trolley to facilitate storage of the trolley.

[0022] Furthermore, the civilized dog walking car also includes a warning sign 6. Fig.23 The warning sign 6 includes a base 61, a vertical wing 62, and a warning word 63; the base 61 is heavy and can be round or square, the vertical wing 62 is inserted in the center of the base 61, and the warning word 63 is located on the vertical wing 62; when an animal defecates in a public place and there is no cart on hand, the warning sign 6 can be placed next to the excrement to attract the attention of passers-by to avoid stepping on the excrement, while also avoiding causing disgust to passers-by.

[0023] Furthermore, the warning sign 6 is made of bright colors to attract the attention of passers-by more easily, and an electronic flashing device can be added to improve the warning effect.

[0024] The civilized dog-walking cart is small in size, easy to operate, and inexpensive, so it is popular with the public. Management departments can encourage dog owners to bring their own carts, and also encourage residential buildings, office buildings, shopping malls, restaurants, park roadsides, and grass fields to be equipped with several such carts for public use. In this way, I believe that the city's sanitation will be greatly improved, the public will be more friendly, and the society will be more civilized and harmonious.
