Description

[Detailed description of the invention] The present invention relates to a makeup brush with a pencil-shaped case, and in particular, to provide a makeup brush with a structure in which two brushes are used by rotating an operating tube and alternately inserting and removing two brushes from the tip of the case. This is the purpose.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In each figure, reference numeral 1 denotes a rotary operation cylinder with a closed upper end, which has a step-like shape with a large diameter section at the bottom and a small diameter section at the top. An operating rod 4 extending upward is integrally provided on a portion of the periphery of the top wall 3. As shown in FIGS. 3a and 3b, the operating rod 4 has a triangular cross section with its base facing inward, and its upper end has an inwardly downward slope.

Reference numeral 5 denotes a gripping cylinder, which has a grooved line 6 around its lower end that fits into the protruding line 2, and a lower part including this grooved line 6 is rotatably fitted into the small diameter part of the operating cylinder 1, and is held upward. A guide plate 7 with two guide holes is fixed to the upper part of its inner surface. The outer diameter of the portion of the grip tube 5 excluding the lower fitting portion is slightly smaller, and the cap 8 is fitted into this smaller diameter portion. Therefore, the cap 8, the lower fitting part of the grip tube 5, and the rotation operation tube 1
The large diameter portions are formed to have approximately the same diameter. still,
If the grip tube 5 is extended, the cap 8 is not necessarily required.

9 and 10 are two brushes. These brushes 9,
The support members 11 and 12 are fixed to the upper ends of long support columns 11 and 12, respectively. The support columns 11 and 12 are inserted into guide holes in the guide plate 7 and hang down to near the bottom of the gripping tube 5. The hanging ends of the support columns 11 and 12 are respectively fitted with elevators 13 and
14 is fixed to the lifting member 11 to constitute a pair of lifting bodies.

Since the elevators 13 and 14 have symmetrical shapes,
To explain one 13, as shown in Figures 4a and 4b, this consists of the periphery of the semicircular part A on the top surface and the periphery of the small area of the bottom surface B, which hangs perpendicularly to one corner of the semicircular part. , the inner surface C is a vertical surface, and the outer peripheral surface D is a conical spherical surface (for convenience, it is referred to as an inverted eccentric semi-conical shape), that is, the shape of the outer peripheral surface D is displaced in the circumferential direction. The degrees of diagonal downward oblique movement are different depending on the position of the elevators 13 and 14, and the elevators 13 and 14 are housed in the grip cylinder 5 so as to be movable up and down, with their vertical surfaces facing each other. Cord-shaped springs 15, 16 surrounding the pillars 11, 12, respectively, are inserted between the elevators 13, 14 and the guide plate 7, and these springs 15, 16 independently move the elevators 13, 14. It is pressed downward.

That is, the elevators 13 and 14 are supported by springs 15 and 16, respectively.
Since the shape is an inverted eccentric semi-conical shape as described above, when the rotary operation tube 1 and therefore the operation rod 4 are rotated in the forward and reverse directions, the circumference of the operation rod 4 relative to the outer circumferential surface of the elevators 13 and 14 changes. The elevators 13 and 14 move up and down by the positional displacement in the direction.

Here, in the present invention, the relationship between the rotation of the rotary operation cylinder 1, that is, the operation rod 4, and the raising and lowering of the pair of elevators 13 and 14 is established as follows. Figure 2 shows a state in which the operating rod 4 is rotated by the rotary operating barrel 1 from the reference position 0° to the maximum operating angle of 180° one half of the way in the direction of arrow A, and the elevator 13 is pushed up to the highest position. As shown in the figure, if the rotary operating barrel 1 is rotated in the direction of the arrow B to return it to the reference position 0° from this state, the elevator 13 will be gradually lowered by the spring 15 in response to this rotation, and the rotating operating barrel 1 will be lowered. When reaching the reference position of 0°, the elevator 13 descends to the lowest position. FIG. 5 is a side view of this state.

Next, if the rotary operation barrel 1 is rotated around the other half in the direction of arrow C from the reference position 0° to the maximum operating angle of 180°,
This time, the elevator 14 is pushed up by the operating rod 4 against the spring 16 and rises to the highest position, and from this state, if the rotary operating barrel 1 is returned to the reference position 0° in the direction of arrow D, it will be at the lowest position. descend to FIG. 6 is a plan view showing the relationship between the rotation operations of the rotation operation barrel 1. As shown in FIG.

Therefore, when the rotary operation barrel 1 is at the reference position 0°, both brushes 9 and 10 are hidden within the cap 8 as shown in FIG. When this happens, either brushes 9 or 10 are sent out from the cap 8.

As mentioned above and shown in the drawings, the cosmetic brush of the present invention has an elongated pencil shape, making it convenient to carry.Also, when not in use, the brushes 9 and 10 are both stored in the cap 8, so the brushes themselves are There is no risk of dirt or other objects being soiled by the brush, and furthermore, it is extremely simple to use as the rotary operation cylinder 1 only needs to be rotated relative to the grip cylinder 5. Further, the mechanism for taking in and taking out the brush is composed of a pair of simple-shaped elevators 13, 14, an operating rod 4, and springs 15, 16, and does not require screws or the like, so it can be easily constructed.
