FIGS. 4 and 5 are schematic views showing the main part of FIG. 3 in plan and side views;

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes a dog brushing hair removal device having a comb 12 on the body 10. The dog brushes that are prone to hair on the comb teeth 12 of the body 10 are illustrated and described, but the invention is not limited thereto. The body 10 has comb teeth 12 formed on at least one surface of the body 10 and has a handle 15 for grasping on one side.

According to the present invention, a movable plate 20 having a through-hole 22 for tightly covering a comb 12 is supported on the body 10 so as to be movable up and down. Although the movable plate 20 having the through holes 22 is a known structure as in the above-mentioned patent documents, tightness surrounding the combs 12 is an important design element. The smaller the clearance between the comb teeth 12 and the through holes 22, the easier hair removal is, and the hair hindering phenomenon can be prevented. However, in this case, since the frictional force required for the up-and-down movement of the movable plate 20 increases, there is a possibility that the hair removing function is lowered or inconvenience due to repetitive operation is caused.

In the detailed configuration of the present invention, the through hole 22 of the movable plate 20 is formed as a long hole to cause a sliding contact with the comb 12. If the area of the comb teeth 12 in the body 10 is formed as a curved surface, the interval between the comb teeth 12 becomes wide, which makes it more difficult to cause the movable plate 20 to smoothly move up and down in a conventional manner. When the through hole 22 is formed as a long hole, the movable plate 20 can be moved up and down, and the hair of the dog is pushed out by the sliding contact of the comb teeth 12 in this process. The length of the slot may be formed differently from the center and the periphery of the comb teeth 12.

According to the present invention, the movable unit (30) has a structure in which the rotary motion of the knob (31) mounted on the body (10) is arranged to switch the up and down movement of the movable plate (20). The movable means 30 causes the movable plate 20 to move up and down by using a force (rotational force) that the user manually rotates the knob 31. [ 1 shows a state in which the knob 31 is rotatably mounted on the outer end of the knob 15 and FIG. 3 shows an example in which the knob 31 is rotatably mounted on the inner end of the knob 15 do.

The movable unit 30 includes a drive shaft 32 concentrically connected to the knob 31, a movable shaft 33 disposed at a lower portion of the movable plate 20 and connected to the drive shaft 32, And a movable link (38) interposed between the movable plate (20) and the movable shaft (33) so as to rotate. The drive shaft 32 is connected to the knob 31 in a concentric manner and is rotatably supported on the body 10. The movable shaft (33) is installed so as to maintain a certain clearance in the lower portion of the movable plate (20). The movable link (38) is provided to switch the rotational motion of the movable shaft (33) to the up and down movement of the movable plate (20). Of course, these actuating means 30 are implemented in somewhat different shapes and sizes in Figures 1 and 3, but operate on the same principle.

Fig. 1 shows an embodiment in which two movable shafts 33 are applied to a brush having a circular body 10, and Fig. 3 shows a modified example in which two movable shafts 33 having a square shaped body 10 are applied . Fig. 1 is suitable for a small brush as compared with Fig. 3, but is not limited thereto. In any case, the movable link 38 is applicable to a structure in which two link members are connected by the joint pin 48. [ The movable link 38 is articulably connected at least one end thereof via a hinge 25 or a ring (not shown).

3, which is a modified example of the present invention, further includes a bevel gear 45 for transmitting power to the opposite movable shafts 33 in the knob 31. As shown in FIG. The rotational force of the knob 31 is transmitted from the concentric drive shaft 32 to the movable shaft 33, the movable link 38 and the movable plate 20 via the bevel gear 45 and the driven shaft 42.

On the other hand, reference numeral 43 for supporting both ends of the movable shaft 33 is indicated by a bearing symbol, but is not limited thereto. That is, a bushing may be used instead of the bearing, or the bearing and the bushing may be excluded, and the same may be supported on the resin material body 10 as it is. The drive shaft 32 is also supported in the same manner as the movable shaft 33.

The movable unit 30 further includes a worm 35 and a worm wheel 36 for increasing the torque in the power transmission path from the knob 31 to the movable plate 20 do. The worm 35 and the worm wheel 36 constituting the worm gear function not only to increase the force (torque) for moving the movable plate 20 but also to prevent the reversal. These worm gears are provided between the knob 31 and the movable plate 20, more effectively between the drive shaft 32 and the movable shaft 33, as shown in Figs.

In the case of Fig. 1, the worm 35 is partly coupled to the drive shaft 32 as shown in Fig. 2 (a), or a worm tooth is formed. 3, the driven shaft 42 between the drive shaft 32 and the movable shaft 33 is constituted by a worm 35, as shown in Fig. In any case, when the knob 31 is turned, a rotational force in a state in which the torque is increased by deceleration is transmitted to the movable plate 20 via the worm gear, the movable shaft 33, and the movable link 38.

In the detailed construction of the present invention, the worm 35 is formed in a double spiral structure having a left spiral and a right spiral so as to be engaged with the one worm wheel 36 and the other worm wheel 36, respectively. In Fig. 2 (a), the worm 35 on one side is the left spiral and the worm 35 on the other side is the right spiral. Since the worm wheels 36 on both sides rotate in opposite directions by the rotation of the knob 31, the two side movable links 38 symmetrically move with respect to the center line as shown in FIG. 2 (b). This can be applied in the same manner in Fig. 4 to implement the same operation.

1 and 2, while the user rotates the knob 31 to one side, the movable link 38 is slowly unfolded to raise the movable plate 20, and the movable plate 20 is brought into close contact with the through- Scrape the comb teeth (12) which are in contact with each other and push the hairs out to remove them. When the knob 31 is turned to the other side, the movable plate 20 descends and returns to the original position, so that the dog can be combed. Of course, even if combing the movable plate 20 at the intermediate positions of Figs. 2 (a) and 2 (b) in consideration of the fur length of the dog, its position is maintained by the worm gear. Such a symmetrical operation of the movable link 38 is useful in the configuration of Fig. 3 in which the pair of movable shafts 33 are arranged in the longitudinal direction of the body 10. [

3 to 5, up and down movement of the movable plate 20 is caused according to the rotating direction of the knob 31 by the same operating principle as that described above. 5, reference numeral 20 'denotes a state in which the movable plate 20 is maximally raised.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
