Slingback for capturing cats that sit on your lap

Abstract

When picking up a cat to put it in a sling bag, the cat would often get upset and try to run away. Because of its floating clavicle and elastic ligaments, the cat was, to put it dramatically, like a jelly-like animal. When picking up a cat with one hand, the human fingers would compress the cat's belly, bones, and chest, resulting in minor harm. Unlike the human body, which has connected clavicles and non-elastic ligaments, cats are delicate. The challenge is to place the cat into the bag without compressing it when it comes onto the owner's lap. [Solution] The bag's sides are designed to be reversible, allowing the bottom surface to be exposed. The bag is then spread out on the owner's lap with the bottom exposed, and when a cat comes onto the bottom surface, the sides of the bag can be reversed, allowing the cat to be placed inside without being touched.

Description

Technical Field

[0001] The present invention relates to a bag for carrying a cat. The bag may be in the form of a neck-hung bag, a shoulder bag, or a sling bag. Hereinafter, these bags are collectively referred to as "the bag" in the present application. In recent years, sling bags for cats have begun to spread. The present application provides a bag characterized by being capable of accommodating a cat without touching the same, so as not to cause discomfort to the cat. To achieve non-contact accommodation, the bag is integrated with the wearer thereof, and is a special bag that acts as a trap for catching semi-wild cats. Background Art

[0002] It is pleasant for an owner when a cat sits on their lap while the owner is sitting working at home. However, this becomes troublesome when the owner wants to leave their seat for a short errand. It is thought that if the cat is placed in a sling bag, the owner can freely stand up and sit down. However, when an owner tries to pick up the cat to put it in the bag, the cat often slips away through the owner's hands. A web search reveals that many owners have this same trouble, which is surprising. According to an online article, things that cats dislike include loud noises, unpleasant odors, being touched when sleeping or by surprise, and they also do not particularly like having their paws, belly or tail touched. However, this does not fully convince people, because cats are fine with these things on days when they are in a good mood. The inventor not only reconsidered this issue from a cat's perspective but also conducted a thorough consideration by imagining the physical structure of a cat. First, if a cat's position is accurately replaced with that of a human, the situation corresponds to a human lying on the lap of a 10-meter giant, and then being lifted by the giant's fingers just like a pallet cargo lifted by the two forks of a forklift. Since the giant's fingers are forced between the human and the ground contact surface, it is painful if they dig into the abdomen, and hurts if they hit a bone. Alternatively, a cat may be lifted by holding its shoulders with both hands. At this time, because cats have a special body structure including floating clavicles and elastic ligaments, a cat's lungs are more easily compressed than human lungs. When putting a cat into a bag, the cat is often held with one hand, which further increases the degree of compression. It is speculated that this is equivalent to a human having their nose and mouth blocked. While this is fine for a short time, it becomes very difficult to breathe if it lasts a long time.

[0003] The conclusion is that "picking up a cat in a relaxed sleeping position and holding it with one hand is a painful, suffocating, and harmful act for the cat." Even if a human holds the cat gently and slowly, it compresses the cat's abdomen, bones, and lungs, causing physical harm. The reason this went unnoticed for thousands of years is that the cat's protests were subtle, consisting of gentle nips, scratches, and moving away, as the pain wasn't severe. Therefore, humans didn't notice the cat's protest behavior and interpreted it as capriciousness. It is also likely that humans, with their connected clavicles and non-elastic ligaments, were unable to perceive the cat's pain. Even after examining prior patent applications for sling bags for cats, there were no prior patents for a design that could accommodate a cat without causing harm. While there are various designs of sling bags, the basic shape of all of them is a deep pocket. Therefore, even if you try to spread the bag on the owner's lap, the sides of the bag's gusset and the handle straps overlap the seat. If a cat comes on top of that, the cat will be sitting on top of the gusset and handles. Then, in order to put the cat into the bag, you have to lift the overlapping parts, which is a design that inevitably causes harm to the cat. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Utility Model Registration No. 3137915: Small Animal Sling (Shoulder Bag for Puppies) [Patent Document 2] Utility Model Registration No. 3129906: Small Animal Sling (Shoulder Bag for Puppies) [Patent Document 3] Utility Model Registration No. 3095896: Small Animal Carrier Bag [Patent Document 4] Utility Model Registration No. 3095095: Pet Bag [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] The objective of this invention is to house a cat in a sling bag without causing harm. As a prerequisite, it is necessary that the sling bag does not prevent the cat from sitting on the owner's lap, so that is also a prerequisite. After considering solutions to the two problems mentioned above, I came up with the idea of ​​a basic configuration where the owner spreads an apron on their lap, and when the cat climbs on, wraps it in the bottom of the apron to create a sling bag. By adding a handle to the bottom of the apron and hanging the handle around the owner's neck, a cat-carrying neck bag is complete. When we tried the prototype apron bag, the cat remained calm and didn't seem to feel much discomfort, staying inside the bag the whole time. The cat didn't seem to mind being lifted up with the apron. When lifted with the apron, the cat's abdomen, bones, and lungs are not compressed, and its entire body remains relaxed, allowing it to stay relaxed. Based on the prototype, the essence of the invention must be that, before placing a cat inside, "the bottom of the bag is exposed, and the sides of the bag can be turned inside out into the space below the bottom, or they can be detached." When placing a cat inside, "the sides of the bag can be turned back without touching the cat, returning the bag to its original shape with the cat still inside." To put it bluntly, without fear of misunderstanding, the challenge in setting the trap for capturing semi-wild cats is to transform the bag so that the bottom surface is exposed. The second challenge in capturing the cat is to create a bag whose sides can be reversed so that the cat can be wrapped and placed inside. The object in question is not particularly complex. However, the bag transforms into two different shapes. Moreover, the shape transformation is not just a standalone transformation; it only makes sense when combined with the "user sitting in a chair with the transformed bag attached." The "pseudo-lap blanket shape" is intended as a trap to catch cats, which are semi-wild animals. The "transformation process into a cat-carrying bag" is a transformation process that allows the bag to be stored without touching the cat, so as not to offend it. [Means for solving the problem]

[0006] The primary objective of this invention is to "contain a cat in a bag without causing harm." The means to achieve this is to spread out the bottom surface of the bag, which can enclose the cat, in the place where the cat is likely to come. Then, when the cat steps onto the bottom surface of the bag, the sides of the bag can be raised to return to their original shape, thus creating a bag that can be restored to its original form. In this plan, the most suitable "place where the cat is likely to come" is on the lap of the owner (the person wearing the bag). The second challenge is "to ensure that the cat does not come onto the wearer's lap." In order for the cat to feel safe enough to climb onto the wearer's lap, first, the edge of the bottom of the bag placed on the wearer's lap must be visible from the cat's perspective on the floor. Furthermore, the sides of the bag and the neck strap must not overlap the bottom of the bag. This can be described as exposing the bottom of the bag, and it has the same meaning as transforming the bag into a pseudo-lap blanket shape. Considering all of this together, the solution would be to construct a bag that can transform into two forms: one that can be transformed into a pseudo-lap blanket shape during the trap-setting stage and another that can be transformed into a bag shape during the cat-catching stage. Before explaining the configuration of the present invention's bag, there is a point that requires attention. When expressing the up, down, left, right, front, and back of the components and their positions, misunderstandings can arise if it is not decided which transformed state and on what basis to express them. In the present invention's bag, when the bag is transformed into a bag, the up, down, left, and right directions will be expressed with the wearer wearing the bag as the reference point. The bottom surface of this cat-carrying bag will be called the bag bottom surface, and the sides surrounding the four sides of this bag bottom surface will be named the ventral side, shin side, left side, and right side, respectively, based on the wearer's reference direction (up and down).

[0007] To express the solution of this invention more specifically, a pseudo-apron is formed that reaches from the wearer's abdomen to their thighs, a first neck strap made of a ring-shaped string that can be worn around the neck is attached to the upper part of this apron, and a second neck strap made of a ring-shaped string is attached to the lower part of this apron, forming a bag-like portion at the bottom of the apron (when the wearer puts the first and second neck straps around their neck) that serves as a cat carrier bag. When transforming into a "pseudo-lap blanket shape" (trap-setting stage), the first neck strap on the ventral side is wrapped around the neck of the wearer seated in a chair, the bottom of the bag is placed on the wearer's lap, the shin-side sides are turned inside out and spread outwards, the second neck strap hangs down to the wearer's feet, and the left and right sides can be turned inside out and spread outwards or removed, respectively, to form a bag. This bag is capable of transforming into a pseudo-lap blanket shape, and the bottom of the bag can be exposed. To enable this transformation, each side is designed to be able to be tightly attached to and easily separated from one another. When transforming into a "cat containment bag shape" (cat capture stage), the bag is constructed by first placing the first neck strap around the user's neck, then adding the second neck strap, and forming the left and right sides using left and right side forming means (through-strap assembly method or drawstring bottom covering method).

[0008] In the case of the aforementioned threaded-through assembly method, threading holes are made in advance at six locations: the upper right ventral side, the upper right shin side, the upper right side of the shin, the upper left side of the shin, the upper left shin, and the upper left ventral side. The starting end of the second neck strap is sewn and fixed to the area near the ventral side that contacts the upper right ventral side when the bag is in its back shape. Then, the second neck strap is threaded through the six threading holes: the upper right ventral side, the upper right shin, the upper right side of the shin, the upper left side of the shin, the upper left shin, and the upper left ventral side. The end of this second neck strap is sewn and fixed to the area near the ventral side that contacts the upper left ventral side when the bag is in its back shape to form the bag. In the case of the aforementioned drawstring bag bottom cover method, a drawstring bag large enough to completely enclose the bottom of the bag is made in advance, an elastic cord is threaded through the opening of this drawstring bag, this drawstring bag is sewn to the lower end of the elastic band, and the upper end of this elastic band is sewn to the upper back of the front side, and the bag is constructed so that (when the first and second neck straps are put around the neck and the drawstring bag is placed over the bottom of the bag from below) the drawstring bag becomes the left side and the right side. The backend is configured to satisfy each of the above constituent requirements. This concludes the solution to the problem. [Effects of the Invention]

[0009] This cat carrier bag allows you to enclose a cat that has come to the bottom of the bag while it remains relaxed, thus "allowing you to house the cat in the bag while maintaining its willingness to stay in it." The cat will remain calm in the bag after being housed, and will also be more likely to come onto your lap. Even if the cat comes onto your lap while you are sitting and working, you can house the cat in the bag, allowing you to stand up and move around without worrying about disturbing your cat. Traditionally, cats were picked up by their owners and placed in a bag. However, this often caused discomfort to the cats due to fingers digging in, bone contact, and lung compression, leading them to escape. Furthermore, cats that had repeated unpleasant experiences would become reluctant to sit on their owners' laps. Because cats have floating clavicles and elastic ligaments, their lungs are easily compressed, and even prolonged improper holding positions can cause them to have difficulty breathing. The bag of this invention is designed to transform into a pseudo-lap blanket shape on the wearer's lap during the trap-setting stage, thus attracting cats by making them think (there are no obstructions on their lap, so they can jump on safely). Furthermore, the bag of this invention is designed so that when a cat is caught, the sides of the bag can be reversed and wrapped around the cat without touching it, thus exhibiting a "feedback effect that encourages cats to stay."

Since it is difficult to illustrate the thickness of the fabric and elastic band, they have been conceptually represented with thicknesses. [Figure 7] It is a perspective view of the backpack of Example 3. MODE FOR CARRYING OUT THE INVENTION

[0011] The sling bag of the present application can be designed as an apron type, a box type, a bag type, or the like. Each type will be described in Examples 1 to 3. EXAMPLES

[0012] With reference to FIGS. 1 and 2, a method of using the bag 1 of Example 1 will be described while describing deformations thereof. FIG. 1 shows a state in which user A, the first person from the left, wears the bag 1 while sitting on a chair B, and the bag is formed into a pseudo knee-laying shape. The second person in FIG. 1 shows a state where a cat C has come onto the bottom surface 2 of the bag. The third person in FIG. 1 shows a state where the bag 1 has a bag shape. If a user holds the round neck strap 10 hanging on the shin side, pulls it, and puts it around the neck, the apron body deforms to enclose the cat C, forming the bag 1. Since no load is applied to the cat C during the process of the cat C getting on the knee and being accommodated in the bag, the cat C can remain relaxed while being housed in the bag 1. This section explains the structure of this bag 1. The bag 1 of this invention, in its bag shape, is located above the knee of the third person in Figure 1. The positions of each component will be explained using the front, back, left, right, up, and down reference points for user A in this bag shape. The bag 1 is formed from fabric made of general apron material, roughly in the shape of an apron. The side in contact with user A's abdomen is the ventral side 3, the side on the shin is the shin side 4, the left side is the left side 5, and the right side is the right side 6. A ring-shaped neck strap 9 is sewn to the upper end of the ventral side 3. A shape-retaining core material 7 is sewn to the upper edges of each side 3 to 6 of the bag 1 in this bag shape. This core material 7 is similar to the core material 7 sewn to the collar of a dress shirt, and the sewing method is also the same. Eyelets 8 are fixed in a total of four places: near both ends of the core material 7 on the left side 5 and near both ends of the core material 7 on the right side 6. Eyelets 8 are donut-shaped metal fittings that serve as holes for threading straps. Two eyelets 8 are attached to each of the two ends of the core material 7 on the shin side 4. There are a total of eight eyelets 8. Then, the neck cord 10 is threaded through the eight eyelets 8 in order at both ends of the core material 7 on the right side 6, both ends of the core material 7 on the shin side 4, and both ends of the core material 7 on the left side 5. When the neck cord 10 is threaded through the first eyelet 8, it comes out from the front to the back of the apron fabric. When it is threaded through the next eyelet 8, the neck cord 10 comes out from the back to the front of the apron fabric. The reason for attaching two eyelets 8 to both ends of the core material 7 on the shin side 4 is to bring the neck cord 10 out to the front of the apron fabric. The starting end of the neck cord 10 is sewn to the right end of the core material 7 on the ventral side 3, and the ending end of the neck cord 10 is sewn to the left end of the core material 7 on the ventral side 3. This process completes the back 1 shown in Figure 2.

[0013] To reiterate, the first person on the left in Figure 1 has user A sitting on chair B with the flat neck strap 9 of bag 1 around their neck and the apron body spread out on their lap like a lap blanket (trap setting stage). When cat C climbs onto their lap, the round neck strap 10 is placed around the user's neck, and the round neck strap 10 pulls on each side 4-6, causing them to stand up and the apron body to transform into a bag shape, allowing cat C to be taken into the bag as shown in the third person in Figure 1 (cat capture stage). After cat C is taken into the bag, user A can stand and walk around and work without worrying about the cat. Although I used apron fabric as an example for easier understanding, the purpose of this invention is not an apron. Therefore, any flexible material such as mesh or leather may be used to construct back 1. [Examples]

[0014] Refer to Figures 3 and 4 to describe the box-type embodiment 2. Embodiment 2 has a similar configuration to embodiment 1, but the bottom surface 12 of the bag and the four sides 13-16 are clearly separated and made of rigid plate material. In Figure 3, the first person from the left is sitting on chair B, wearing the bag 11, with the bag 11 spread flat on his lap. In Figure 3, the second person has a cat C on the bottom surface 12 of the bag. In Figure 3, the third person has the bag 11 in its bag shape. By holding the round neck strap 20 hanging down on the shin side and pulling it, the sides 14-16 of the rigid plate material rise up to enclose the cat C, forming a box-shaped bag 11. The structure of the bag 11 in Example 2 will now be explained. The bag 11 of this application is located above the knee of the third person in Figure 3. The positions of each component will be explained using the user's front, back, left, right, up, and down orientation as a reference for this bag shape. The side in contact with the user's abdomen is the abdominal side 13, the side facing the shin is the shin side 14, the left side is the left side 15, and the right side is the right side 16. An apron body in the shape shown in Figure 4 is cut out, and a core material 17 for maintaining the shape is sewn onto the shin side 14, the left side 15, the right side 16, and the bottom surface 12 of the bag. The core material 17 used in Example 2 is a hard material similar to the brim of a hat. In Figure 4, the dotted patterned surfaces represent the surfaces into which the core material 17 is sewn. Only the core material 17 on the bottom surface 12 of the bag is a concave curved surface to soften the contact with the user A's abdomen. Rings 18 for threading strings are sewn onto both ends of the outer upper edge of the shin side 14, the left side 15, and the right side 16 (a total of 6 places). Then, as in Example 1, the neck strap 20 is threaded through the six rings 18, and both ends of the neck strap 20 are sewn to the ventral side 13 to complete the bag 11. The method of using the back 11 in Example 2 is the same as in Example 1, and the deformation is as shown in Figure 3. [Examples]

[0015] A third example of a bag-type bag will be described with reference to Figures 5, 6, and 7. Example 3 is a bag 21 that employs a drawstring bag bottom covering method as a means of forming the left and right sides. In Figure 5, the first person from the left is sitting on chair B, with a cat C on the bottom of the bag spread out over his lap. In Example 3, the bag 21 transforms from a pseudo-lap blanket shape to a bag shape in two stages. The second person's bag 21 in Figure 5 is in the first stage of bag transformation, and is transformed by putting the neck strap 23 on the shin side around the neck. The third person's bag 21 in Figure 5 is in the state after completing the second stage of transformation, and is transformed by covering the bottom of the bag with the drawstring bag 24 sewn to the back of the abdominal side. The structure of the bag 21 in Example 3 will now be described. A narrow rectangular pseudo-apron, approximately the width of the body, is formed. A ring-shaped flat neck strap 22 is sewn to the upper end of this apron, and a ring-shaped round neck strap 23 is sewn to the lower end of this apron. Furthermore, a drawstring bag 24 is formed that is large enough to put over the apron wrapped around the cat C from below. An elastic cord is threaded through the opening of this drawstring bag 24, and this drawstring bag 24 is sewn to the lower end of the elastic band 25. The upper end of this elastic band 25 is sewn to the upper back of the ventral side to complete the bag of Example 3. The method of using the bag in Example 3 is the same as in Example 1, and the deformation is as shown in Figure 5. The flat neck strap 22 and the round neck strap 23 may be configured with a wider width only in the area that directly touches the neck to reduce pressure on the neck and shoulders. Also, although the example bag has an open top that allows cat C to escape, it is possible to make it so that escape is not possible by covering the top with a cloth or closing it with a zipper. [Industrial applicability]
