Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a click motion device that rotates while positioning.

[Conventional technology]

Conventionally, there has been a click motion device as shown in FIG. 6 that rotates while positioning. That is, the shaft 52 of the fixed member 51 is connected to the rotating member 53.
A bolt 57 is passed through the center hole 54 of the shaft 52 and screwed onto the shaft 52, and a rotating member 53 is rotatably connected to the fixed member 51. Furthermore, the fixing member 51
A plurality of holes 51a are provided in the circumferential direction on the joint surface of the rotating member 53, and a ball member 55 that fits into the hole 51a and a spring 56 that presses the ball member 55 are provided on the joint surface of the rotating member 53. Therefore, the rotating member 5
3 relative to the fixed member 51, it becomes difficult to rotate when the ball member 55 fits into the hole 51a, but otherwise rotates smoothly. Therefore, the rotating member 53 can be fixed at a predetermined position on the fixed member 51.

[The problem that the idea attempts to solve]

However, in the conventional click motion device, it is necessary to form parts such as a ball member, a spring, etc., and a recess for accommodating them, which causes problems in that machining is troublesome and costs are increased.

The present invention was devised in view of the above-mentioned problems, and an object of the present invention is to provide a click motion device that can be manufactured at low cost and easily.

[Means to solve the problem]

The click motion device according to the present invention was devised to achieve the above object, and has the following configuration.

(a) Consists of a fixed member and a rotating member.

(b) A fixed magnet shall be provided on the side surface of the fixed member, and a rotating magnet shall be provided on the side surface of the rotating member.

(c) The rotating member shall be configured such that its rotating magnet is joined to the fixed magnet of the fixed member so that it can freely rotate relative to the fixed member.

(d) The joint surfaces of the fixed magnet and rotating magnet shall be magnetized with different magnetic poles alternately radially from approximately the center.

[Effect]

Since the click motion device according to the present invention has the above configuration, when the rotating member is rotated with respect to the fixed member, the rotating magnet rotates while being connected to the fixed magnet. Different magnetic poles are alternately magnetized on the joint surfaces of the rotating magnet and the fixed magnet, so if the same magnetic poles overlap, they will repel each other and the rotating member will rotate smoothly, but if different magnetic poles overlap, they will attract each other. rotation becomes difficult. Therefore, the rotating member makes a click movement with respect to the fixed member.

〔Example〕

An embodiment in which the click motion device according to the present invention is applied to the joints of a doll will be described below with reference to FIG.

Reference numeral 1 denotes a hollow doll body molded from synthetic resin, and a circular magnet 2 with a hole 2a formed in the center is embedded in the shoulder portion. The surface 2b of this magnet 2 has different magnetic poles N radially from the center,
S is alternately magnetized. 3 is a doll's upper arm molded from synthetic resin, and a circular magnet 4 with a hole 4a formed in the center is embedded in the base, and a shaft member 3a of the upper arm 3 projects from this hole 4a. It's becoming like that. This magnet 4 is also the magnet 2
Similarly, different magnetic poles N and S are alternately magnetized radially from the center on the surface 4b.

Therefore, when the shaft member 3a of the upper arm part 3 is inserted into the hole 2a of the magnet 2, the magnets 4 and 2 are attracted to each other, and the upper arm part 3 is easily attached to the body 1. When this upper arm part 3 is rotated, the surface 4b of the magnet 4 embedded therein and the surface 2b of the magnet 2 embedded in the torso 1
The upper arm part 3 is connected with the shaft member 3a as the center.
rotates. At this time, the surface 2b of the magnet 2 and the magnet 4
When the surfaces 2b of the magnets 2b are joined with the same polarity, they repel each other and the magnets 4 separate, and when they are joined with different polarities, they attract each other and are attracted to each other. Therefore, when the surfaces 2b of the magnets 2b are joined with the same polarity, they attract each other and are attracted to each other. Rotation becomes difficult. Therefore, the upper arm part 3 can be fixed in a state tilted at a predetermined angle with respect to the body 1. Note that by making the magnetized regions of the magnets 2 and 4 thinner, the angle of inclination of the upper arm portion 3 can be made thinner.

In the above embodiment, the shoulder joint of the doll was explained, but it goes without saying that it can be used for the neck joint, ankle joint, etc.

Next, another embodiment in which the present invention is applied to a toy gun battery will be described based on FIG. 2.

Reference numeral 11 is a cannon barrel molded from synthetic resin, and circular magnets 12 with a hole 12a formed in the center are embedded symmetrically on both sides of the base thereof. On the surface 12b of the magnet 12, different magnetic poles N and S are alternately magnetized radially from the center. 13
is a base molded from synthetic resin, and is composed of two halves 14 and 15. A circular magnet 16 with a hole 16a formed in the center is embedded in the side wall 14a of one divided body 14, and the other divided body 1
A circular magnet 17 with a hole 17a formed in the center is embedded in the side wall 15a of the magnet 5, and the holes 16a, 17
Shaft members 14b, 15 of side walls 14a, 15a from a
b is starting to stand out. This magnet 16,
Similarly to the magnet 12, the magnet 17 also has surfaces 16b and 17b.
Different magnetic poles N and S are alternately magnetized radially from the center, but when embedded in the side walls 14a and 15a, they are embedded so that the different poles face each other rather than symmetrically.

Therefore, the cannon barrel 11 is assembled by inserting the shaft members 14b, 15b of the divided bodies 14, 15 of the base 13 into the holes 12a formed on both sides of the barrel 11.
By integrating 5 with bolts, adhesive, etc.
It will be rotatably attached to the base 13.
When the cannon barrel 11 is rotated, the surface 12b of the magnet 12 embedded therein is exposed to the side walls 1 of the base 13.
Surface 1 of magnets 16 and 17 embedded in 4 and 15
The barrel 11 rotates around the shaft members 14b, 15b while being connected to either one of the shaft members 6b, 17b. At this time, the surface 12b of the magnet 12 and the magnet 1
When the surfaces 16b and 17b of 6 and 17 are joined with the same polarity, they repel each other, and when they are joined with different polarities, they attract each other.
The above-mentioned rotation is performed smoothly when the poles are of the same polarity, but rotation is difficult when the poles are of different poles. Moreover, the magnet 16,
17 is embedded so that the opposite poles face each other, so for example, in FIG. 2, the magnet 16 and the gun barrel 1
1 When the magnet 12 on the left side is attracted to each other, the magnet 17 and the magnet 12 on the right side of the gun barrel 11 are repelling each other, so the gun barrel 11 is strongly pressed against the side wall 14a, and in the opposite case, The gun barrel 11 is the side wall 1
5a, and the gun barrel 11
can be fixed more strongly than in the embodiments described above in a state where it is tilted at a predetermined angle with respect to the base 13.

Furthermore, another embodiment in which the present invention is applied to a transmission will be described based on FIG. 3.

Reference numeral 21 indicated by a two-dot chain line is a mission case, and a circular magnet 22 with a hole 22a formed in the center is embedded in the upper part. The surface 22b of this magnet 22 has different magnetic poles N and S radially from the center.
are alternately magnetized. Reference numeral 23 denotes a speed change lever, which is composed of a grip portion 23a, a central shaft portion 23b, and a swing shaft portion 23c. This central shaft portion 23b
is inserted into the hole 22a of the magnet 22, and a circular magnet 24 is fixed thereto. The lower surface 24b of this circular magnet 24 is connected to the surface 22b of the magnet 22, and similarly to the surface 22b of the magnet 22, different magnetic poles N and S are alternately magnetized radially from the center. ing. 26
is a sliding gear part that is slidably attached to a driving shaft 27 provided in the case 21, and has a large gear 26a and a small gear 26b, and has a large gear 26a and a small gear 26b.
The tip of the gear c is adapted to engage with a recess 26c surrounded by a large gear 26a and a small gear 26b. Further, the large gear 26a slides to mesh with a small gear 28a fixed to the driven shaft 29, and the small gear 26b also slides to mesh with a large gear 28b fixed to the driven shaft 29.

Therefore, when the shift lever 23 is rotated, the lower surface 24b of the magnet 24 fixed thereto rotates while being in contact with the surface 22b of the magnet 22 embedded in the case 21. At this time, when the lower surface 24b of the magnet 24 and the surface 22b of the magnet 22 are connected with the same polarity, they repel each other, and when they are connected with different polarities, they attract each other, so the rotation described above is performed smoothly between the same polarities, and the rotation is performed between the opposite polarities. becomes difficult. Therefore, the shift lever 23 can be fixed in a state tilted at a predetermined angle with respect to the case 21, so that, for example, when the large gear 26a is engaged with the small gear 28a or when the small gear 26b is engaged with the large gear 28b, can be maintained.

Furthermore, another embodiment in which the present invention is applied to a toy car will be described with reference to FIG.

Reference numeral 31 indicated by a two-dot chain line indicates the body of a toy car, and a circular magnet 32 with a hole 32a formed in the center is embedded in the upper part. The lower surface 32b of this magnet 22 has different magnetic poles N radially from the center,
S is alternately magnetized. Reference numeral 33 denotes a handle lever, which is composed of a grip portion 33a, a central shaft portion 33b, and a swing shaft portion 33c.

This center shaft portion 33b is connected to the hole 32 of the magnet 32.

4 is fixed, and the magnet 34 is attached to the swing shaft portion 33c.
It is embedded in the base 33d of. The upper surface 34b of this circular magnet 34 is connected to the lower surface 32 of the magnet 32.

Similar to the lower surface 32b, different magnetic poles N and S are alternately magnetized radially from the center. 36, 36
is a steering member that is swingably provided on the vehicle chassis, and its front end is connected by a connecting member 37.
A recess 37a is formed approximately at the center of the connecting member 37, and the tip of the swing shaft 33c engages with the recess 37a.

Therefore, when the handle lever 33 is rotated, the upper surface 34b of the magnet 34 fixed to the handle lever 33 moves against the body 3.
The magnet 32 rotates while being in contact with the lower surface 32b of the magnet 32 embedded in the magnet 1. At this time, the upper surface 34b of the magnet 34
When the lower surfaces 32b of the magnets 32 are connected with the same polarity, they repel each other, and when they are connected with different polarities, they attract each other. Therefore, the above-mentioned rotation is performed smoothly when the poles are the same, but rotation is difficult when the poles are the same. Therefore, since the handle lever 33 can be fixed in a state tilted at a predetermined angle with respect to the body 31, for example, when the handle lever 33 is rotated to the right, the connecting member 37,
The front wheels can be maintained in a rightward direction via the steering member 36, and conversely, when rotated to the left, the front wheels can be maintained in a leftward direction.

As explained above, the click motion device according to the present invention can be used in various fields, and therefore is not limited to the above embodiments.

Further, in the above embodiment, the shape of the magnet is circular, but it goes without saying that it may be square, triangular, or the like.

Furthermore, in the click exercise device according to the present invention,
Intermittent metallic sounds are generated due to the repulsion and attraction of the joined magnets, which can be interesting.

Furthermore, in the above embodiments, the rotation of the rotating member is restricted by the shaft member, but it may be arranged as shown in FIG. 5. That is, a boss portion 43 having a fitting recess 42 is formed at the base of the fixing member 41, and a fixed magnet 45 having a thickness thinner than the depth of the fitting recess 42 is embedded in the fitting recess 42. The surface 45b of this magnet 45 is also magnetized with different magnetic poles N and S alternately radially from the center. On the other hand, a boss portion 48 having a fitting recess 47 is also formed at the base of the rotating member 46, and a rotating magnet 49 that is thicker than the depth of the fitting recess 47 is embedded within the fitting recess 47. The surface 49b of this rotary magnet 49 is also magnetized with different magnetic poles N and S alternately radially from the center.

The upper part 49a of this rotating magnet 49 is fixed to the fixing member 41.
Even if the rotary member 46 is fitted into the fitting recess 42, the rotation of the rotary member 46 is restricted as in the previous embodiment.
