Description

WO 00/65906 PCT/CAOO/00465 -1 MANURE OR URINE COLLECTING DEVICE WORN BY THE ANIMAL Technical Field This invention relates to a device for mounting or wearable on a domestic animal particularly on a dog for collecting its excrement. Background Art Human invents flush toilets to dispose of our body excrements, but has neglected to provide similar means for removing excrements for our domestic animals such as dogs. Most responsible dog owners do take precaution to clean up the excrment for their dogs; however, often dogs are allowed to defecate and leave the excrement on roadways, public park lands, and even on the lawns of private properties. The excrement not only creates an unhealthy environment but it also fouls the roadways, and public park lands such that people can not have free enjoyment of these public places without the danger of being soiled by such animal waste. Furthermore, leaving dog excrement on other people's lawn and property is grossly irresponsible of the dog owner and it is an encroachment on the private property right. For generations, dogs bring to people a lot of appreciated functions and happiness such as guarding against burglars, rescuing owner from danger and guiding blind people to cross the street. Till today's industrial society, dogs are the lonely people's best friends and they can reduce family conflicts between the busy working parents and their children. As a result, nowadays, dogs live with their owners as a member of the family in our society; in addition, regarding the pets' inoculation, the pet-owners or the whole society spend great efforts in preventive medicine to resolve important problems. Yet till recently, even though much work is done in researches in order to provide nutritious foods for the dog and to explore the best inoculation for maintaining its health, there is one issue left for a long time without much attention, namely, the dogs' sanitary facilities. Because of this lacking, many families owning dogs are painfully spending a SUBSTITUTE SHEET (RULE 26) WO 00/65906 PCT/CAOO/00465 -2 lot of money on their dogs, and such big expenses inherently decrease these families' life quality and environmental sanitation. Human invent flush toilet to solve the problem of disposing our own body's excrement, but we forget to help the "other kind" of the family members by providing similar equipment for solving the dogs' same basic body needs. This is a big and serious shame for this high standard society which improves human's ecology, but ignores the same problem facing their pet animals. People who love horses like to clean the horse excrement quickly so as to maintain the horse barn in a clean condition so as to maintain the air in the barn fresh to breath. They try to carry out the cleaning jobs as a daily routine for preventing the horses from stepping on the manure and spreading it around to create a hard to remove stinky smell in the barn. The horse owner pay a high cost and labor to maintain such cleanliness. However, often time, they may use an excessive amount of water to wash the barn which can cause a negative impact on the environment. The present invention not only can solve the above problems in a reasonable way, but can also improve the quality of the environment to bring happiness to the people who love 5 horses. With the use of the present invention, dairy cows can stay in a healthy environment to produce clean milk and it reduces the need of using clean drug and high medicine such as antibiotics to maintain their good health. The present invention lends itself to changing the "cow barn" into a "cow house" which can be just as clean as a human house. At the same time, a large D amount of the excrement can be collected for use as a high quality natural fertilize, which can reduces the pollution of the environment and stress. As a result, it will provide the best quality of milk with the daily cost of as little as two shopping bags. Moreover, the cow's excrement can be collected and cleaned at one place completely so as to resolve the threats and troubles to the environment pollution of the society by the animal farming business. SUBSTITUTE SHEET (RULE 26) WO 00/65906 PCT/CAOO/00465 -3 The issues and problems which may be resolved by the present invention are illustrated in the following examples and explanations: a. For example, it is not a pleasant experience when we take a walk in the public park and step on some animal excrement. When we pass by the grass or sit down on any bench in the park 5 and noticing animal excrement around us, this is another unpleasant evidence. Fortunately, majority of dog owners are aware of cleaning up after their dogs in order to keep the environmental sanitation. However, the feeling of bending down and cleaning up dogs' excrement is similar to cleaning up a person's excrement regardless of the different opponents. As a consequence, we become our lovely dogs' long term servants! We feel awkward and embarrassed 0 by doing this disrespectful service. Inconspicuously, we develop resistance and confusion in our mind, somehow, we already built up a strong relationship with our dogs. By doing so for years especially for an elderly person, this is certainly bad for the blood pressure and there is such an urgent need to solve this problem immediately. b. For the majority of dog owners can not sleep late in the morning because of the mental 5 pressure of having to arrange for their dog's defecation. Such mental pressure exists regardless if the owners are retired people. All dog owners must necessarily wake up on time every day including weekends and holidays by putting away their fatigue, just to serve their adorable dogs. They worry that their dog would defecate inside the house which is difficult to clean and it fouls the air in the house to present another difficult task for cleaning. The excrement may not be simply 0 cleaned by watering, since it would result in a tremendously wet place; and furthermore, the bad smelly polluted water would flow into the septic tank to result in the increase in pollution for people who live in an apartment and are restricted by the space. Therefore, many dog owners must clean the dog's excrement and remind themselves repeatedly to remember that the first thing to do each morning would be to clean up the dog's excrement. This task present more burden SUBSTITUTE SHEET (RULE 26) WO 00/65906 PCT/CA0O/00465 -4 for an elderly dog owner because of the long period of not feeling free from the anxiety and worry such that they can not sleep comfortably; as a result, they are more prone to having a lot of medical problems, accordingly the stressful situation must be resolved right away. c. Suspicious dog owners: Walking dogs in the park is one of the happiest moments for dog owners; however, they may become suspicious to other people who are also using the park. For example, a dog owner may be suspected of not having cleaned up the dog's excrement in the park even though the excrement is not discharged by his dog. No one saw the previous dog owner who did not clean up after his dog; therefore, nobody would blame the previous dog owner. By saying "hello" or smiling to other people in the park becomes an unpleasant experience, since he or she may be the one who is being suspicious of leaving dog excrement in different places on the grass in different times previously. The dog owners must squeeze their heart tightly and hope to show on their faces that they are innocent dog owners and that they are not the ones who do not take responsibility for their dog's excrement. This results in a very unhealthy pressure in their heart for many dog owners. Doctors who specialized in heart treatment warn their patients to avoid as much as possible such unnecessary stress to their heart. d. The reason for the subconsciousness of realizing having violated a civil regulation for a long period of time and the shame of yet letting it happening repeatedly: Some dog owners taking their dogs to the park by car, would push their dogs off the car quickly and they would get off the car slowly and take a slow walk. In the meantime, their dogs would run around the park to defecate freely. The dog owners knowing that their lovely dogs have already finished defecating would then simply bring their dogs home without cleaning after their dogs even though the excrement causes environment pollution and it causes other people trouble. When such habit continues day after day, year and year, it could cause a shameful conflict in the conscience of such irresponsible dog owners. Day after day, it causes unhealthy thoughts such as anxiousness and SUBSTITUTE SHEET (RULE 26) WO 00/65906 PCT/CAOO/00465 -5 depression to build up for some of those unhealthy people. This subconscious shame would show on their face as if they have stolen a small object in a department store every day. Unconsciously, this bad habit becomes part of these people's character. e. Labor service is a very expensive service in our society nowadays. Manufacturers help us to eliminate time-consuming activities by offering us meat packing in the supermarket and electrical equipment. Yet, considering over the life of a long live dog, a dog owner would have spent a tremendous amount of time in cleaning after the dog than the time he would spend in performing any other labor service. Sometimes, the dog may change its defecating time or the owner may vary his schedule of taking it out for a walk. On the street, we may see some dog owners leading their dogs with one hand and holding a plastic excrement collecting bag in the other hand, and because of the above mentioned schedule changes some owners may forget to bring toilet paper and the excrement collecting plastic bag so that after the dogs have defecated, the owners can only stand there and become perplex of what to do next. Thus, cleaning up excrement is a worthless labor service. In our society today, a lot of dog owners spend tremendous amount of time in caring their pets with affections and, in doing so, the owners have become the dogs' slaves. This is an oppressed situation. The above examples well illustrate the circumstances facing most dog owners today. My idea is to help to resolve the unseen, untouched problem in our environment. I hope I can give a complete resolution of the problem. The advantages of the present invention are as follows: a. From now on, we can surely solve the dog owner's labor service for their dogs and reduce the obstacle to their regular sleeping schedule to the minimum. b. We help our dogs to improve their life quality just the way we help our living quality by using flush toilet; in addition, it improves the ecological environment. SUBSTITUTE SHEET (RULE 26) WO 00/65906 PCT/CAOO/00465 -6 c. Dog owners use different unofficial tools and materials to remove their dog's excrement. My invention helps to simplify all of these unnecessary steps and solves this problem totally. d. The most important consequence is to bring happiness to the elderly dog owners and to put them in the position of able to rest at ease. They can reduce the causes of high stress and anxiety. All of these help the whole society to reduce the high expenses in the use of resources and it is beneficial for people to change their bad habits that are caused by caring for the dog. e. The device of my design can be provided on the dog in advance without having to dispose of the excrement collection bag right away. Accordingly, it helps to alleviate all the problems mentioned above; and it would be pleasant and convenient to bring the dog in visiting friends or in traveling. f. From now on, we will no longer meet frequently dog owners leading a dog with one hand and holding a plastic excrement collection bag in the other hand, and wasting their time, awaiting their dog to defecate. This brings happiness to these dog owners. g. In addition, the benefits of this invention can solve potential conflicts, arguments stresses, and water pollution in city areas around the animal farming business. h. The present invention can truly change a "milk cow barn" to a "milk cow house". . Since discovering the problem, and researching and designing to resolve the problem, my invention helps to bring awareness to such issue in our society of high standard of living. Personally, in consideration of the importance of such knowledge, I wish to support others to further the study in this area, and I wish to devote 30% of the net profit derived from the present invention to people who come from very poor families and who respect their parents and their family members so that they may continue their study in this area.

A circular opening 74 having an expandable extension slit 75 is formed in the diaper strap 70 to SUBSTITUTE SHEET (RULE 26) WO 00/65906 PCT/CAOO/00465 -17 permit the tail of the dog to extend therethrough. A generally L-shaped attachment tubular member 76 is mounted on the diaper strap 70. The tubular member 76 has a collection opening 77 which will abut the anus of the dog when the harness 12 is properly mounted on the dog. The tubular member 76 has a free end 78 extending outside from the diaper strap 70 for receiving an excrement collection bag (not shown) to be removably mounted thereto, and an excrement collection bag supporting pouch 79 is provided on the strap to support the weight of the excrement collection bag after it has been filled. A slit opening 80 is formed in the diaper strap 70 to permit the penis of a male dog to be extending therethrough, and a urine collection bag as shown in Figure 45 may be mounted on the diaper strap 70 for collecting the urine discharge from the dog. A urine collection bag supporting pouch 81 is provided on the diaper strap to support the weight of the filled urine collection bag after it has been filled such that the latter would not dislodge from the mounting when the dog is moving or running. As best shown in Figure 45, the urine collection bag is provided with a back flow preventing valve 82 to prevent leakage of the urine from the bag when it is filled. The valve 82 may be in the form of a pivotal flap attached to one side of the neck of the bag. A further alternative embodiment of the device according to the present invention is best shown in Figure 47. The disposable harness 12 is similar to that shown in Figure 41, except the excrement collection bag 83 is in the form of a flexible bag having a stiff mounting neck portion 84 with an enlarged rim 85 such that the excrement collection bag 83 may be mounted to the diaper strap 70 by simply inserting the enlarged rim 85 through a slit opening 86 formed in the diaper strap 70. Similarly, the urine collection bag 87 has a substantially L-shaped neck portion 88 and an enlarged mouth 89 which may be inserted through the slit opening 80 for mounting to the diaper strap 70 for collecting any urine discharge from the dog. The urine collection bag 87 is also provided with a back flow preventer valve 90 to prevent the urine inside the bag to spill SUBSTITUTE SHEET (RULE 26) WO 00/65906 PCT/CAOO/00465 18 outwards therefrom. The urine collection bag 87 is also provided with a back flow preventing valve 90 as best shown in Figure 48. It can be appreciated that the present device not only greatly reduces the hardship of requiring the dog owner to face the problem of having to walk the dog outdoors even during adverse weather conditions and having to wait for the dog to defecate and then cleaning after it, but it also eliminates the potential of any unattended dog excrement from contaminating the ecological environment. Obviously numerous modifications and variations of the device of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practised otherwise than as specifically described herein. As stated above, I would encourage others to improve on the present device and I would like to donate 30% of the profit derived from the present invention to those who require financial assistance in seeking such further improvements to my invention.
