RU222262U1 - Scratching post with the possibility of repeated replacement of working material - Google Patents

Abstract

The utility model relates to light industry, and more specifically to products for caring for animals, mainly cats, and is intended for use in sharpening claws. A scratching post for cats consists of four main elements: 1) clamp 1 (Fig. 1); 2) block for sharpening claws 2 (Fig. 1); 3) base 3 (Fig. 1); 4) legs 4 (Fig. 1), in the amount of three pieces. The block for sharpening claws is made in the form of a pipe 22 (Fig. 3) with a rope 29 wound around it in a spiral (Fig. 4). The ends of the rope 29 (Fig. 4) are fixed at the opposite ends of the pipe using crowns 16 (Fig. 3,4), 28 (Fig. 3, 4). The outer diameter of the pipe 22 (Fig. 3) and the rope 29 (Fig. 4) can be different. But the internal diameter of the pipe 22 (Fig. 3) depends on the diameter of the selected rope 29 (Fig. 4). The formula for calculating the minimum internal diameter of pipe 22 (Fig. 3) is as follows: Dmin=4Dk+17, where Dmin is the minimum internal diameter of pipe 22 (Fig. 3), mm; Dk – rope diameter, mm. The claw sharpening block is attached to the base 3 (Fig. 1) by placing it on a pin 31 (Fig. 5), which passes through the holes 17 (Fig. 3,4) of the crowns 16 (Fig. 3, 4), 28 (Fig. 3 , 4) and is fixed with clamp 1 (Fig. 1). The stability of the entire structure is ensured by three legs 4 (Fig. 1), which are screwed into the base body at an angle of 120° relative to each other. The entire structure (Fig. 1) is installed vertically on any horizontal surface. In case of wear of the rope 29 (Fig. 4), the spent rope is removed from the crowns 16 (Fig. 3,4) and 28 (Fig. 3, 4), unwound from the pipe 22 (Fig. 3) and disposed of. Restoring the working surface of the sharpening block occurs by fixing one end of the rope on the crown 16 (Fig. 3, 4) from the end of the pipe 22 (Fig. 3), winding the rope to the crown 28 (Fig. 3, 4), located at the opposite end of the pipe 22 (Fig. 3) and fixing the second end of the rope on the crown 28 (Fig. 3,4). The winding order is reverse. The diagram of fixing the rope in the crown is shown in Fig. 4. The possibility of replacing the working material of the rope 29 (Fig. 4) ensures the durability of this scratching post in comparison with similar models, which are completely recycled after the working material of the claw sharpening block is worn out.

Description

The utility model relates to light industry, and more specifically to products for caring for animals, mainly cats, and is intended for use in sharpening claws.

A scratching post-post for cats is known, containing a post with a rope wound around it, which is mounted on a base and secured. The post is most often made of cylindrical wood with a diameter of 50 mm and a height of 400 mm. A rope with a diameter of 5 mm is secured to a post with glue. The base is most often made of a square-shaped sheet of plywood or chipboard, the length and width usually do not exceed 500 mm, and the thickness is 16 mm (see GB 2611173 A, 03/29/2023).

The disadvantage of the known scratching post is that the rope of the claw sharpening block (post) is torn by the cat's claws, rendering it unusable. After this, it is necessary to replace the block for sharpening the claws (column) with a new one, if the design of the scratching post provides for this possibility, or replace the entire claw post, which is not economically viable.

The technical problem that the claimed utility model is aimed at achieving is to increase the service life of a cat scratching post without installing new replacement parts.

The technical result to be achieved by the claimed utility model of a cat scratching post is that the cat scratching post contains a base with a block for sharpening claws installed on it, which is fixed with a clamp and three legs for installation on a horizontal surface, while the design of the block for sharpening claws provides the possibility of replacing the rope after it is worn out, and it is also possible to replace the entire claw sharpening unit after the rope is worn out.

The cat scratching post ensures its high durability without installing new replacement parts due to the ability to use the same block for sharpening claws.

To achieve the above technical result, a block for sharpening claws with the ability to replace the rope was developed. The system for fixing the rope on pipe 22 (Fig. 3) consists of two crowns - 16 (Fig. 3,4) and 28 (Fig. 3,4), which hold the rope on pipe 22 (Fig. 3) without any adhesive composition. The base 3 (Fig. 1) is also designed for the possibility of mounting a block for sharpening claws 2 (Fig. 1) on the base 3 (Fig. 1) with subsequent fixation with a clamp 1 (Fig. 1). The stability of the entire structure is ensured by a support in the form of a tripod, consisting of three screw-in legs 4 (Fig. 1) into the base 3 (Fig. 1). Additionally, the legs 4 (Fig. 1) are equipped with anti-slip caps 61 (Fig. 5).

Thus, the claimed utility model of the scratching post provides the ability to repeatedly replace the rope without the use of additional means and tools, which is as cost-effective as possible.

The scratching post for cats consists of four main elements: clamp 1 (Fig. 1), block for sharpening claws 2 (Fig. 1), base 3 (Fig. 1), legs 4 (Fig. 1) - three pieces.
