  The present invention relates to a device for collecting excrement of pet animals, and more particularly, to a device for collecting excrement of dog for sanitary treatment of excrement discharged during walking of a dog in a simple and low cost manner.

Conventionally, excrement discharged during a walk of a dog cannot be left as it is, especially in residential areas, so carry a plastic bag or paper bag, pick up the fallen stool with a scoop, etc. It was. At this time, the excrement of pets such as dogs often has a strong odor, and if it comes into contact with the hands, it is difficult to remove the odor and it is not preferable for hygiene, so this situation should be improved. Various collection devices have been proposed.

For example, as a method of collecting excrement before it falls to the ground, there is a type of collection device that attaches a bag-like object to the dog's bottom, or a bag-like object at the end of a rod-like object There was a type in which the collecting device was made to follow the buttocks of the dog by hand according to the movement of the dog. However, in the former type of collection device, it often shifts due to the dog's intense movement, or when the dog sits in the middle of excretion, it shifts from the buttocks and does not function. In order to follow the movement of the dog, if the dog moves violently during excretion, or if the dog's excretion timing cannot be judged accurately, the excrement will be dropped on the ground, eventually falling to the ground In many cases, it would be necessary to collect the materials manually.

For example, Patent Document 1 discloses a collection device in which an outer frame provided with a handle is hollowed and a bag-like object is glued to the hollowed portion, but a follow-up operation to a dog's buttocks is required. For this reason, it was inevitable that spilled excreta was lost. For this reason, after all, a recovery device for recovering excrement once dropped on the ground is required, and various recovery tools have been proposed. Such a technique is disclosed in, for example, Patent Document 2 or Patent Document 3, and among these, in Patent Document 2, a scissor-like excrement gripping device is provided with a locking portion that locks the bag portion, and the gripping device.

Preferred embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram showing a schematic configuration of a waste collection device 10 according to an embodiment of the present invention. As shown in FIG. 1A, the excrement collection instrument 10 of the present embodiment is connected so that the left and right arm portions 40 are movable via a connecting portion 50 in the vicinity of one tip portion. The collection bag support 20 is connected to the other tip of the arm 40. A collection bag 30 is connected to the collection bag support unit 20.
Here, the collection bag support portion 20 has a substantially cylindrical tubular structure that is open at both ends (the cross section may be circular, elliptical, or substantially rectangular), and the collection bag 30 is It has a bag-like shape with one end opened.

The collection bag 30 is formed in such a manner that the opening of the collection bag 30 is once passed through the inside of the inner diameter portion of the collection bag support 20 and the opening is folded back by a predetermined width. It is attached to the outside of the support portion 20. Here, the folded portion of the collection bag 30 is fixed by a predetermined fastener.
With such a configuration, the left and right arm portions 40 are configured such that the other end portion can be opened and closed with the connecting portion 50 as a fulcrum.
Further, a connecting angle adjusting unit 52 is connected to the left and right arm portions 40 in the vicinity of one end, and the connecting angle adjusting unit 52 allows a scissor angle (opening / closing angle) of the left and right arm portions 40 to be a predetermined angle or more. It is restricted not to open.

Further, an elastic body 60 is fixed to the left and right arm portions 40, and a force that widens the scissor angle (opening / closing angle) of the left and right arm portions 40 acts by the elastic body 60. After narrowing the opening and closing angle by applying a force in the direction of narrowing (the force in the direction of pressing the left and right arm portions 40 from the outside) and then releasing the pressing force, the reaction force of the elastic body 60 is then applied to the left and right arms. The part is automatically opened and can return to the opening / closing angle limited by the connecting angle adjusting part 52. Then, the excrement that has fallen on the ground applies a force to press the left and right arm portions 40 from the outside, so that the left and right introduction ports 30A sandwich the excrement and pass through the inside of the collection bag support portion 20 from the introduction port 30A. Then, it is collected in the collection bag 30.

Moreover, as an arm part and an elastic body used for this invention, not only the Example described in FIG. 1 (A) but the following structures may be sufficient.
For example, as shown in FIG. 1B, the plate-like elastic body 60 can be deformed into a coil spring-like elastic body 62. In this case, the elastic body 62 is arranged so as to surround the connecting portion 50 so that the connecting portion 50 and the central axis are common. Then, both ends of the elastic body 62 are linearly extended so as to be in contact with the left and right arm portions 40, respectively. For this reason, the elastic body 62 always applies a force that widens the scissor angle (opening / closing angle) of the left and right arm portions 40, and applies a force in the direction of pressing the left and right arm portions 40 from the outside of the arm portion. After narrowing the opening / closing angle, just release the pressing force, and then the left and right arm parts automatically open due to the reaction force of the elastic body 62 until the opening / closing angle limited by the connecting angle adjusting part 52 is reached. You can go back.

Alternatively, as shown in FIG. 1 (c), the arm portion may be configured so as not to provide an elastic body separately from the arm portion but to give elasticity to the entire arm portion or a part of the arm portion. In this case, the arm portion 42 is configured to include linear portions 42B and 42C that extend to the left and right with the curved portion 42A as the center. The arm part 42 can be configured to have elasticity at least in the curved part 42A. For this reason, after applying a force in the direction of pressing the left and right arm portions 42 from the outside of the arm portion to narrow the opening and closing angle, it is only necessary to release this pressing force, and then the reaction force based on the elasticity of the curved portion causes the left and right The arm part can be automatically opened and returned to the original opening / closing angle.

In FIG. 2, the collection bag support portion 20 is connected to the end portion 40 </ b> D of the arm portion 40, and a state in which the collection bag support portion 20 is connected at an angle α that forms a slight acute angle with respect to the axis of the arm portion 40 is shown. However, the present invention is not limited to this. For example, the connection angle α can be adjusted with a bolt or the like.

FIG. 3 is a side view showing the configuration of the excrement collection device according to the embodiment of the present invention as seen from the X direction in FIG. Here, in FIG. 3, the cross-sectional shape of the collection bag support portion 20 is shown by a circular broken line, but this cross-sectional shape is not limited to a circle but may be an ellipse or a rectangle.

FIG. 4A is a diagram showing a mechanism until the collection bag 30 is connected in combination with the collection bag support portion 20 in the embodiment of the present invention.
The collection bag support part 20 has an outer surface (20A to 20C) and an inner surface (20D), and has a cylindrical shape with a substantially cylindrical cross section with both ends open. The outer side of the collection bag support portion 20 is composed of a large outer diameter portion 20A, a step portion 20B, and a thin outer diameter portion 20C, and the inner side of the collection bag support portion 20 is continuous from the large outer diameter portion to the thin outer shape portion. It is comprised by the internal diameter part 20D which has a cross-sectional shape.
Here, the material of the collection bag support portion 20 has a shape that includes the above-described stepped portion (or a concave portion or a convex portion) and needs only to have a certain level of strength, for example, paper such as cardboard. It may be made of a material, or may be a material such as a resin typified by metal or plastic. In this regard, for example, when a resin is used, it can be made transparent or translucent, and in that case, there is an effect that it is possible to work while visually confirming whether or not excrement has been captured.

In addition, it is not always necessary that the step part (or the concave part or the convex part) is formed over the entire circumference, and only two step parts (or the concave part or the convex part) are provided facing each other. There may be. The inner diameter of the collection bag support 20 is adjusted by adjusting the size of one opening (upper part) and the other opening (lower part: a part connected to the cavity of the collection bag 30). It is possible to prevent the excrement once taken into the cavity of the collection bag 30 from leaking outside (for example, the lower opening is narrower than the upper opening).
The collection bag 30 has a bag-like structure with an opening at the top. For example, a bag made of vinyl or polyethylene can be used, or a bag of paper can be used.

The fixing device 70 has a function of fixing the vicinity of the opening 30A of the collection bag 30 to the stepped portion 20B of the thin outer diameter portion 20C of the collection bag support portion 20, and the inner shape thereof is a cross section of the thin outer diameter portion 20C. It has a shape that is almost equal to the outer shape.
The fixing device 72 is a rubber band-like device having elasticity, and has the same function as the fixing device 70.
The collection bag 30 passes through the opening 30A from the lower part of the collection bag support part 20 to the upper part of the collection bag support part 20 along the inner diameter part 20D. The opening is folded back by a predetermined width and is fixed outside the collection bag support 20 by a fixing device 70 or 72. The width at which the collection bag 30 is folded back is sufficient if it is at least the width of the large outer diameter portion 20A outside the collection bag support portion 20 plus the width necessary for fixing with the fixing device 70 or 72.
In addition to the folded portion of the collection bag 30 being fixed by the fixing device 70 or 72, the pinching portion 30B is formed by the presence of the step 20B, so that the collection bag 30 can be easily removed from the collection bag support portion 20. It is fixed so that it does not slip so as not to come off.

As described above, since the collection bag 30 and the collection bag support unit 20 are combined with the left and right arm units 40 having a structure that can be opened and closed, the collection bag support unit 20 is covered by the collection bag 30 and As a result of part of the collection bag 30 forming the introduction part 30A, the excrement can be collected simply by operating the left and right arm parts 40. It becomes possible to collect excrement without polluting the unit 20. And since the collection | recovery bag 30 is disposable, there exists an effect that it can be stored hygienically without polluting the excrement collection | recovery instrument. Further, since the collection bag can be diverted to a shopping bag or a garbage bag, it can be constructed at a low cost and has an excellent economic effect.

In FIG. 4A, the large outer diameter portion 20A is shown to have a certain thickness, but for example, an annular cardboard or the like may be attached to the thin outer portion, and the main point is the step 20B. It is only necessary to form a concave portion or a convex portion, and the shape is not limited to the illustrated shape.
Further, the opening of the large outer diameter portion 20A is shown in FIGS. 4A (A) and (B) as having a certain thickness, but is not limited to this, and is made of, for example, metal or resin. In such a case, the thickness may be changed in a tapered shape like the introduction portion 20E of the collection bag support portion shown in FIG. 4A (c). According to such a shape of the opening portion, a certain thickness is generated in the opening portion depending on the material of the collection bag support portion 20, but it is not affected by the material and prevents the excrement from being caught when the excrement is taken up. be able to.

FIG. 4B is a diagram illustrating an example in which a collection bag support unit 22 is used instead of the collection bag support unit 20. As described above, in order to fix the folded portion of the collection bag, it is sufficient to provide a stepped portion (or, as a result, a concave portion or a convex portion), and as shown in FIG. By providing the groove 22B, the same function as described above can be achieved. Of course, in this case as well, it is not necessary to provide a groove over the entire circumference, and it is only necessary to provide a notch portion so as to face a part.
In this case as well, as in the description of FIG. 4A, the collection bag support portion 22 is covered with the collection bag 30 and a part of the collection bag 30 forms the introduction portion 30A. It is possible to collect excrement without polluting the collection bag support part 20 as well as human hands.
In FIG. 4A and FIG. 4B, the total lengths of the collection bag support portion 20 and the collection bag support portion 22 are shown slightly longer than the outer diameter. However, the total length is not limited to this. It may be formed to be the same or shorter than the diameter.

According to FIG. 5, the collection bag 30 passes through the inner diameter portion 20 </ b> D on the inner side of the collection bag support portion 20 to the right end opening portion of the collection bag support portion 20 and then passes through the opening portion of the collection bag 30. A state in which the bag is folded by a predetermined width is fixed on the outside of the collection bag support portion 20 by the fixing device 70 or 72.
Also, it is shown that the inner diameter portion 20D inside the collection bag support portion 20 has a substantially continuous cross section (as opposed to having a step 20B on the outside). As a result, the excrement 90 can smoothly pass through the inner diameter portion 20 </ b> D and be introduced into the collection bag 30.

FIG. 6 (a) is a diagram showing a schematic configuration of an excrement collection instrument according to an embodiment of the present invention. FIG. 1 shows an example in which the collection bag support portion 20 is connected to the ends of the left and right arm portions, but it is sufficient that the collection bag support portion 20 is provided in either one of the arm portions. As shown, a lid portion 80 (such as a lid for the opposing collection bag support portion 20) may be provided at the tip of the arm portion on one side.
In this case, as shown in FIG. 6B, the lid portion 80 is covered with a bag-like object 32 having an opening portion, and the opening portion is attached to the arm portion 42 by a substantially “U-shaped” fastener. It may be fixed. Further, as shown in FIG. 6C, the shape of the lid 80 may be formed in a substantially rectangular parallelepiped, and a sealing member 34 that covers the entire lid 80 may be attached to the surface. When such a configuration is taken, the excrement can be collected without soiling the lid 80 when the excrement is collected. And since the bag-like thing 32 and the sealing member 34 are disposable, there exists an effect that the excrement collection | recovery instrument can be stored hygienically.

FIG. 7 is a schematic side view showing the operation of the excrement collection instrument according to the embodiment of the present invention based on the configuration shown in FIG.
According to FIG. 7 (a), by applying a force to press both side portions 42C and 42B of the arm portion 42 from the outside, the bending portion 42A is bent and the interval between the lid portion 80 and the collection bag support portion 20 is narrowed. To go. Next, the lid part carries the excrement 90 to the introduction port of the collection bag support part 20 while pushing it. Then, the excrement 90 is gradually carried into the collection bag support portion 20 and dropped into the collection bag 30 and collected by tilting the excrement collection device 10 as a whole.

  FIG. 7 (b) is a view showing a mechanism for taking excrement when the projection 82 </ b> A is provided on the lid 82. By providing this protrusion 82A, it is carried into the inlet so as to support the lower part of the excrement, so that the excrement can be reliably recovered.

FIG. 8 is a schematic perspective view showing an outline of the excrement collection device when it is configured to have a connection angle between the arm part, the lid part, and the collection bag support part. FIG. 9A shows a state of viewing this from the x1 direction and the x2 direction.
According to FIGS. 8 and 9 (a) and 9 (b), the recovery bag support 24 is inclined by an attachment angle θ from a direction (vertical direction) perpendicular to the bottom surface of the recovery bag support. 42B is connected, and similarly, the arm portion 42C is connected to the lid portion 84 so as to be inclined by the attachment angle θ. Here, in the same manner as described with reference to FIG. 4A, the collection bag support portion 24 has a horizontal portion partially extending in the cross section, which is composed of an outer surface (24A to 24C) and an inner surface (24D). It has a cylindrical shape with a surface.

Next, based on FIG. 8, an operation in the case where the excrement collection instrument has this structure will be described.
First, by applying a force to the left and right arm portions to be pressed from the outside by a human hand 100, the curved portion is deformed, and the interval between the lid portion 84 and the collection bag support portion 24 is narrowed. Move. Then, the excrement 90 is carried to the inlet of the collection bag support portion 24 so as to be pushed by the lid portion 84. In this case, the arm portion 42B, the collection bag support portion 24, and 42C, and the lid portion 84 each have a structure that is inclined by the attachment angle θ, so that the arm portion 42B is maintained with the wrist 102 being substantially straight. 42C can be operated, so if the attachment angle θ is not given (when θ is approximately 0 degrees), it is necessary to return the wrist and operate, compared to that case, it is necessary to return the wrist. There is an effect that the operation can be made easily.

In this case, when the collection bag support portion 24 is formed of a thick member, the lower part of the introduction port for introducing the excrement is gradually introduced toward the entrance (toward the entrance). A slant portion having a slant shape (which reduces the thickness) may be provided.
9A and 9B show a configuration in which the mounting angle θ is fixed. However, as shown in FIGS. 9C and 9D, the mounting angle θ can be adjusted. It may be.
