Description

Technical Field

[0001] The present invention relates to a claw sharpener for cats, and more particularly to a claw sharpener for cats that also serves as cat furniture.

Background Art

[0002] Cats have fast-growing claws and need to sharpen their claws frequently. In households, they use wooden furniture to sharpen their claws, which causes a lot of damage to the furniture. Therefore, conventionally, claw sharpeners for cats that can be used indoors have been used. In FIG. 6 of Japanese Patent No. 7405339, an invention of a claw sharpener for cats is disclosed in which a dome-shaped cover is attached on top of a box-shaped storage part that houses a claw sharpening member, and cats can sleep in it. Also, in FIG. 1 of Utility Model Registration No. 3054686, a claw sharpener for cats is disclosed in which a claw sharpening member is provided on the roof of a triangular cat furniture with an empty interior.

[0003] A claw sharpener for cats that also serves as cat furniture has the merit of saving the installation space and cost of cat furniture and claw sharpeners for cats. However, conventional claw sharpeners for cats that also serve as cat furniture have a fixed shape as furniture, and cats easily get bored with them.

[0010] In these figures, 1 is a cat scratching post made from multiple pieces of cardboard. This cat scratching post 1 consists of a combination of lower and upper first and second cat scratching post members 2 and 3, and is designed to be used in conjunction with cat furniture. Specifically, the cat scratching post 1 has a tunnel-shaped horizontal opening 4. The horizontal opening 4 has an internal space, into which cats can enter and exit, or lie down on their sides. The first and second cat scratching post members 2 and 3 are formed symmetrically.

[0011] The lower first cat scratching post 2 has a cup shape with a base when viewed from the front (see Figure 4). The first cat scratching post 2 includes a laminated scratching post 2a formed by stacking many flat, identically shaped corrugated cardboard pieces 21a upright in the front-to-back direction and integrating them by adhesive. Thick, reinforcing corrugated cardboard pieces 21b, which have the same shape as the corrugated cardboard pieces 21a when viewed from above, are glued to the front and back to form an integrated structure. The corrugated cardboard pieces 21a and 21b have a cup shape with a base at their lower ends (see Figures 5 and 6). The first cat scratching post member 2 has a base portion 22, a left rising portion 23, a right rising portion 24, and a large-diameter upward-facing first recess 25 recessed below these portions. The height of the left end 26 (upper surface of the left rising portion 23) and the right end 27 (upper surface of the right rising portion 24) of the upper surface of the first cat scratching post member 2 is the same. The left end 26 of the upper surface is a wave-shaped first fitting portion 29 including a central mountain-shaped fitting projection 28, and the right end 27 of the upper surface is a wave-shaped second fitting portion 31 including a central mountain-shaped fitting projection 30. The fitting projection 28 protrudes upward toward the third fitting portion (reference numeral 40 in Figure 7) of the second cat scratching post member 3, which will be described later, and the fitting projection 30 protrudes upward toward the fourth fitting portion (reference numeral 42 in Figure 7), which will be described later. The first cat scratching post component 2 has a scratching surface on its top.

[0012] The upper second cat scratching post 3 has a cup shape that faces downward when viewed from the front (see Figure 7). The second cat scratching post 3 includes a laminated scratching post 3a formed by stacking many flat, identically shaped corrugated cardboard pieces 31a upright in the front-to-back direction and integrating them by adhesive. Thick, reinforcing corrugated cardboard pieces 21b, which have the same shape as the corrugated cardboard pieces 21a when viewed from above, are glued to the front and back to form an integrated structure. The corrugated cardboard pieces 31a and 31b have a downward-facing cup shape with ears on the left and right sides of their upper ends (see Figures 8 and 9). The second cat scratching post member 3 has a pair of left and right ear portions 32, a top portion 33 with ear portions 32 attached, a left downward-sloping portion 34, a right downward-sloping portion 35, and a large-diameter downward-facing second recess 36 recessed above these portions. The height of the left end 37 (underside of the left downward-sloping portion 34) and the right end 38 (underside of the right downward-sloping portion 35) of the lower surface of the second cat scratching post member 3 is the same. The left end 37 of the lower surface is a corrugated third fitting portion 40 including a central valley-shaped fitting groove 3, and the right end 38 of the lower surface is a corrugated second fitting portion 42 including a central valley-shaped fitting groove 41. The fitting groove 39 can be fitted and detachably fitted with the fitting projection 28, and the fitting groove 41 can be fitted and detachably fitted with the fitting projection 30. The second cat scratching post component 3 has a scratching surface on its underside.

[0013] When the second cat scratching post 3 is placed on top of the first cat scratching post 2 from above and pressed down, the third fitting part 40 fits detachably into the first fitting part 29. At the same time, the fitting groove 39 fits detachably into the fitting projection 28, and the fourth fitting part 42 fits detachably into the second fitting part 31, and the fitting groove 41 fits detachably into the fitting projection 30, so that the first and second cat scratching post 2 and 3 become one unit. The first recess 25 and the second recess 36 then combine to form a single horizontal hole 4. The horizontal hole 4 has a space inside which a cat can enter and exit and lie down on its side. In addition, the entire inner surface of the horizontal hole 4 is a scratching surface, so a cat can enter and scratch its claws.

[0014] Next, the method of using the above-described embodiment will be explained. The first cat scratching post component 2 can be used on its own or as a bed-shaped cat scratching post with its top surface as the scratching surface (see Figure 4). By placing the second cat scratching post 3 on top of the first cat scratching post 2 and pressing it down, engaging the first fitting part 29 and the third fitting part 40, and engaging the fourth fitting part 42 with the second fitting part 31, it can be used as a house-shaped cat scratching post 1 with a side opening 4 that allows the cat to enter and exit and lie down on its side (see Figures 10 and 1). The second cat scratching post 3 can also be used as a bed-shaped cat scratching post by reversing its orientation so that the second recess 36 faces upward and is supported by the left and right ear portions 32 (see Figure 11).

[0015] According to this embodiment, by placing the second cat scratching post 3 on top of the first cat scratching post 2 and fitting them together in two layers, a cat scratching post 1 can be realized that can also be used as a cat furniture with a single side opening for the cat to enter, exit, and lie down on. Furthermore, by removing the second cat scratching post 3, the first cat scratching post 2 can be used alone as a bed-shaped scratching post with a first recessed area 25 at the bottom. Also, the second cat scratching post 3 can be used alone as a bed-shaped scratching post with a second recessed area 36 at the bottom by reversing its orientation. Furthermore, the first cat scratching post 2 and the second cat scratching post 3 are fitted together in two stages, upper and lower, by a fitting structure that includes a fitting projection 28 and a fitting groove 39 extending in the front-rear direction on the left end of the first and second cat scratching post 2 and 3, and a fitting structure that includes a fitting projection 30 and a fitting groove 41 extending in the front-rear direction on the right end of the first and second cat scratching post 2 and 3. As a result, the second cat scratching post 3 is less likely to come off even when a cat enters and exits the lateral hole 4, and the structure is stable. [Examples]

[0016] Next, a cat scratching post according to a second embodiment of the present invention will be described with reference to Figures 12 to 20. Figure 12 is a front view of the cat scratching post according to the second embodiment of the present invention, Figure 13 is a top view of Figure 12, Figure 14 is a left side view of Figure 12, Figures 15(1) to (3) are a front view, top view, and left side view of the third cat scratching post member in the middle of Figure 12, Figures 16(1) to (3) are a front view, top view, and left side view of the laminated corrugated cardboard scratching post piece in Figure 15, Figures 17(1) to (3) are a front view, top view, and left side view of the laminated corrugated cardboard scratching post piece in Figure 15, and Figures 18 to 20 are explanatory diagrams of the assembly method of the cat scratching post of Figure 12. Note that the same reference numerals are used for the same components as in the first embodiment described above. The second embodiment is a cat scratching post that also serves as cat furniture, combining three upper and lower cat scratching post components. By combining the three components, it is possible to form two horizontal holes on the top and bottom.

[0017] In Figures 12 to 14, 1A is a cat scratching post made from multiple pieces of cardboard. This cat scratching post 1A consists of three layers: the first and second cat scratching members 2 and 3 in the lower and upper sections, and the third cat scratching member 5 in the middle section, and is designed to be used in conjunction with cat furniture. Specifically, the cat scratching post 1A has two tunnel-shaped upper and lower first and second horizontal openings 6 and 7, allowing cats to enter and exit the internal space of the first and second horizontal openings 6 and 7, or to lie down in the internal space. The first, second and third cat scratching members 2, 3 and 5 are formed symmetrically.

[0018] The third cat scratching post 5 has a gutter shape when viewed from the front (see Figure 15). The third cat scratching post 5 includes a scratching post laminate 5a formed by stacking many flat, identically shaped corrugated cardboard pieces 51a upright in the front-to-back direction and integrating them by adhesive, and thick, reinforcing corrugated cardboard pieces 51b, which have the same shape as the corrugated cardboard pieces 51a when viewed from above, are glued to the front and back to integrate them (see Figures 16 and 17). The third cat scratching post member 5 has a left downward-sloping portion 52 and a left upward-sloping portion 53 at its left end, and a right downward-sloping portion 54 and a right upward-sloping portion 55 at its right end. Between the left downward-sloping portion 52 at the left end and the right downward-sloping portion 54 at the right end, there is an upwardly recessed third recess 56, and between the left upward-sloping portion 53 at the left end and the right upward-sloping portion 55 at the right end, there is a large-diameter downwardly recessed fourth recess 57.

[0019] The height of the left end 58 (the lower surface of the left downward-sloping portion 52) and the right end 59 (the lower surface of the right downward-sloping portion 54) of the lower surface of the third cat scratching post member 5 are the same. The left end 58 of the lower surface is a wave-shaped fifth fitting portion 61 including a central valley-shaped fitting groove 60, and the right end 59 of the lower surface is a wave-shaped sixth fitting portion 63 including a central valley-shaped fitting groove 62. The fitting groove 60 can be fitted and detachably fitted with the fitting projection 28 of the first cat scratching post member 2, and the fitting groove 62 can be fitted and detachably fitted with the fitting projection 30. The fitting projection 28 of the first cat scratching post member 2 protrudes upward toward the fifth fitting portion 61 of the third cat scratching post member 5, and the fitting projection 30 protrudes upward toward the sixth fitting portion 63.

[0020] The height of the left end 64 (upper surface of the left rising portion 53) and the right end 65 (upper surface of the right rising portion 55) of the upper surface of the third cat scratching post member 5 are the same. The left end 64 of the upper surface is a wave-shaped seventh fitting portion 67 including a central mountain-shaped fitting projection 66, and the right end 65 of the upper surface is a wave-shaped eighth fitting portion 69 including a central mountain-shaped fitting projection 68. The fitting projection 66 protrudes upward toward the third fitting portion 40 of the second cat scratching post member 3, and the fitting projection 30 protrudes upward toward the fourth fitting portion 42. The fitting projection 66 can be fitted and detachably fitted into the fitting groove 39, and the fitting projection 68 can be fitted and detachably fitted into the fitting groove 41. The third cat scratching post component 5 has scratching surfaces on both its top and bottom.

[0021] When the third cat scratching post 5 is placed on top of the first cat scratching post 2 from above and pressed down, the fifth fitting part 61 fits detachably into the first fitting part 29. At the same time, the fitting groove 60 fits detachably into the fitting projection 28, the sixth fitting part 63 fits detachably into the second fitting part 31, and the fitting groove 62 fits detachably into the fitting projection 30, becoming a single unit. The first recess 25 and the third recess 56 then combine to form a single first horizontal hole 6. The first horizontal hole 6 has a space inside which a cat can enter and exit and lie down on its side. Furthermore, the entire inner surface of the first horizontal hole 6 is a scratching surface, allowing a cat to enter and scratch its claws.

[0022] When the second cat scratching post 3 is placed on top of the third cat scratching post 5 from above and pressed down, the third fitting portion 40 fits detachably into the seventh fitting portion 67, and at the same time, the fitting groove 39 fits detachably into the fitting projection 66, while the fourth fitting portion 42 fits detachably into the eighth fitting portion 69, and at the same time, the fitting groove 41 fits detachably into the fitting projection 68, becoming one unit. The fourth recess 57 and the second recess 36 then combine to form a single second horizontal hole portion 7. The horizontal second hole portion 7 has a space inside which a cat can enter and exit and lie down on its side. In addition, the entire inner surface of the second horizontal hole portion 7 is a scratching surface, allowing a cat to enter and scratch its claws. The first and second cat scratching posts 2 and 3 have the same configuration as in the first embodiment.

[0023] Next, the method of use of the second embodiment described above will be explained. The first cat scratching post component 2 can be used on its own or as a bed-shaped cat scratching post with its top surface as the scratching surface (see Figure 4). The second cat scratching post 3 can also be used as a bed-shaped cat scratching post by reversing its orientation so that the second recess 36 faces upward and is supported by the left and right ears 32 (see Figure 11). The third cat scratching post component 5 can also be used independently as a bed-shaped cat scratching post with its top surface as a scratching surface (see Figure 15).

[0024] By placing the third cat scratching post 5 on top of the first cat scratching post 2 and pressing it down, engaging the first fitting part 29 and the fifth fitting part 61, and engaging the sixth fitting part 63 with the second fitting part 31, it can be used as a house-shaped cat scratching post 1a with a first side opening 6 that allows the cat to enter, exit, and lie down on its side (see Figures 14 and 15). The top surface of the third cat scratching post 5 is bed-shaped. The cat can scratch both the inner surface of the first side opening 6 and the top surface of the cat scratching post 5.

[0025] By placing the second cat scratching member 3 on top of the cat scratching post 1a shown in Figure 19 and pressing it down, fitting the seventh fitting part 67 and the third fitting part 40, and fitting the fourth fitting part 42 into the eighth fitting part 69, it can be used as a fish-shaped cat scratching post 1A with two upper and lower first and second horizontal holes 6 and 7 that allow cats to enter, exit, and lie down on their sides (see Figures 20 and 12). Cats can scratch their claws on the inner surfaces of the first and second horizontal holes 6 and 7. Furthermore, by placing the second cat scratching post 3 on top of the first cat scratching post 2 and pressing it down, engaging the first fitting part 29 and the third fitting part 40, and engaging the fourth fitting part 42 with the second fitting part 31, it can be used as a house-shaped cat scratching post 1 with a side opening 4 that allows cats to enter and exit and lie down on their sides (see Figures 10 and 1).

[0026] According to this second embodiment, by placing and fitting the third cat scratching post 5 on top of the first cat scratching post 2, and then placing the second cat scratching post 3 on top of the third cat scratching post 5 to fit them in three stages (upper, middle, and lower), a cat scratching post 1A can be realized that can also be used as cat furniture with two upper and lower first and second horizontal holes 6 and 7 that allow cats to enter, exit, and lie down. Furthermore, even if the second cat scratching post 3 is removed, it can still be used as cat furniture 1a with one horizontal hole. Moreover, even if the first cat scratching post 2 and the third cat scratching post 5 are used individually, they can be used as a bed-shaped cat scratching post with an upwardly recessed first recess 25 and a fourth recess 57. Also, even if the second cat scratching post 3 is used individually, by reversing its orientation, it can be used as a bed-shaped cat scratching post with a downwardly recessed second recess 36. Furthermore, by fitting the first cat scratching post 2 and the second cat scratching post 3 in two stages, one above the other, it can be used as a cat scratching post 1 that also functions as cat furniture and has a single horizontal hole 4. Furthermore, the first cat scratching post 2 and the third cat scratching post 5 are fitted together vertically and detachably by a fitting structure including a fitting projection 28 and a fitting groove 60 extending in the front-rear direction on the left end side, and a fitting structure including a fitting projection 30 and a fitting groove 62 extending in the front-rear direction on the right end side. As a result, even if a cat enters and exits the lateral hole 6, the third cat scratching post 5 is unlikely to come off, and the structure is stable. Furthermore, the third cat scratching post 5 and the second cat scratching post 3 are fitted together vertically and detachably by a fitting structure including a fitting projection 66 and fitting groove 39 extending in the front-rear direction on the left end side, and a fitting structure including a fitting projection 68 and fitting groove 41 extending in the front-rear direction on the right end side. As a result, the second cat scratching post 3 is less likely to come off even when a cat enters and exits the lateral hole 7, and the structure is stable.

[0027] In the first and second embodiments described above, fitting protrusions were provided on the first and second fitting parts of the first cat scratching post member and on the seventh and eighth fitting parts of the third cat scratching post member, and fitting grooves were provided on the third and fourth fitting parts and on the fifth and sixth fitting parts. However, conversely, fitting grooves may be provided on the first and second fitting parts of the first cat scratching post member and on the seventh and eighth fitting parts of the third cat scratching post member, and fitting protrusions may be provided on the third and fourth fitting parts and on the fifth and sixth fitting parts.
