DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a receiving portion in contact with one surface of an earlobe and a fastening portion in contact with multiple surfaces of the earlobe.
The present invention relates to a step-type tightening device for tightening an earlobe by moving a tightening portion in a direction of a receiving portion to wear ear ornaments.

[0002]

2. Description of the Related Art A method of wearing earrings to an earlobe includes:
There are a screw (screw) type, a clip (sandwich) type, a piercing (piercing) type, and the like. Although the former two methods, which do not require perforation, can be easily used by anyone, there is a problem in that they are unsuitable. The clip type is the simplest but does not allow any adjustment, and in most cases it is either loose or painful. Therefore, the screw type occupies the mainstream, but has a drawback that it is difficult to maintain a constant tightening force as usual with screwing. Once loosened due to shaking or vibration during wear, the screw does not return to its original position unless it is re-closed, so there are many cases where the screw is easily detached from the earlobe and lost.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and the problem is that the attachment and detachment are easy.
In addition, it is an object of the present invention to provide an apparatus for wearing ear ornaments, which can maintain a constant tightening force and has high safety.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a main body in which a receiving portion is arranged on one side and a fastening portion is arranged on the other side, and a through-hole portion for passing the fastening portion is provided in the main body. , The fastening part is provided with a plurality of grooves in the moving direction,
The engagement with the groove, the protrusion having a curved surface that can be detached, the engagement,
A means is provided for being incorporated in the main body so as to be movable in the disengagement direction, and for urging the projection elastically in the engagement direction.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The device of the present invention has a receiving portion in contact with one surface of an earlobe and a tightening portion in contact with the other surface of the earlobe, and tightens the earlobe by moving the tightening portion toward the receiving portion. , Belongs to the device to wear earrings.
In such an apparatus configuration, the present invention is characterized in that the tightening position can be selected stepwise.

[0006] The receiving portion and the tightening portion are for clamping the earlobe from both sides. It can be said that the receiving part is the side that receives the compression by the tightening part, while the tightening part is the side for operating. Therefore, in the place where the decorative body as the ear decoration is attached,
The receiving side will be selected.

The device according to the invention has a body for arranging the receiving part on one side and the clamping part on the other.
Thus, the body is a means for providing the receiving part and the fastening part in the proper positions. When the receiving portion and the fastening portion are provided on both sides of the main body, the space between the receiving portion and the fastening portion is a space for accommodating the earlobe. But you should not be trapped in this look.

[0008] The main body is provided with an opening for passing the fastening portion. The opening is provided for movably passing the fastening portion and holding it by means described later. The tightening portion can be moved in the direction of the receiving portion, and has a plurality of grooves provided in the moving direction. This groove serves as one element of the positioning means for holding the fastening portion at a desired position. The projection having a curved surface that can be engaged and disengaged from the groove is incorporated into the main body so as to be movable in the engagement and disengagement directions. The projection is the other element of the positioning means, but exerts a resilient action to always urge in the direction of engagement. Various springs can be used to obtain this force.

[0009] An isolation portion may be provided between the grooves. The isolation part adjusts the pitch by isolating the adjacent groove part and makes an edge at the boundary.

The projection is preferably a spherical surface or a cylindrical surface. These curved surfaces securely engage with the shallow groove portion and are easy to disengage, and the accuracy of the curved surface gives a sense of moderation to the engagement and disengagement operations. Since the size of the protrusion consisting of a curved surface, the depth of the groove, and the angle of the slope forming the groove and the pitch are important factors for smooth engagement and disengagement, the optimal numerical values that have been studied beforehand are selected. Is done.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the drawings. The device of the embodiment has a receiving portion 11 on one side.
And the other side has a main body 10 in which a fastening portion 12 is arranged. Between the receiving portion 11 and the fastening portion 12 is a space 13 into which an earlobe enters.

The body 10 of the embodiment is formed in a substantially U-shape.
Has a structure in which a tubular member 15 having an opening 14 is attached to the other end side so as to movably attach the fastening portion 12 toward the receiving portion 11. It is assumed that the opening 14 is correctly oriented in the direction of the receiving portion 11.

The fastening portion 12 is a shaft-like member that is long in the moving direction, and has a contact 12a for contacting the earlobe at the distal end and an operating member 12b for moving operation at the base end. A plurality of grooves 16 are provided in an intermediate portion of the fastening portion 12 in the moving direction. The groove portion 16 is formed in a shallow, substantially V-shaped configuration with a gentle slope, and an isolation portion 17 is provided between the adjacent groove portions 16, and a pitch interval of the groove portion 16 including the isolation portion 17 will be described later. The diameter is set to be substantially the same as the diameter of the sphere as 18. This pitch is also set smaller than the diameter of the sphere.

In the embodiment, a steel ball for a ball bearing is used as the projection 18. Therefore, a high-precision product can be obtained at a relatively low price. A steel ball having the above-mentioned diameter is provided in the tubular member 15 by elastic biasing means 19.
And can be engaged with and disengaged from the groove 16. Therefore, the ratio of the protrusion 18 entering the groove 16 is shallow, and is set to 10% to 40% of the diameter (or the pitch), preferably about 20%.

In order to engage the projection 18 with the groove 16,
As the elastic urging means 19, the coil spring is a cylindrical member 1.
5 is incorporated. The coil spring is assembled in a compressed state between the end of the main body 10 and the steel ball, and the tightening portion 12 having the groove 16 is pressed by the urging force into the cylindrical member 1.
5 is pressed against the closed end member 20. At this time, it is desirable that two or more shaft portions or isolation portions on both sides of the groove contact the end member 20 and the wall surface of the passage portion 14 at the same time.

The decorative body 21 is attached to the opposite side of the receiving portion 11. In addition, the above-mentioned contact 12a and operation element 12b
Are attached to both ends of the shaft of the fastening portion 12 by caulking or the like. In addition. In the case of the embodiment using steel balls for the projections 16, a stainless steel wire is used for the biasing means 19, and the other components are formed of a material that can withstand the use of these steel balls and steel wires.

Therefore, by gripping the operating element 12b with a fingertip and pushing or pulling the fastening portion 12 in the axial direction, the projection 18 engaging with the certain groove portion 16 is pushed to the isolation portion 17 by a shallow slope, The next groove 16 is engaged. During the engagement, the projection 18 is seated in the groove 16 and is stable without loosening, and is also caught on the edge 22 at the boundary between the groove 16 and the isolating portion 17, so that there is no possibility that the projection 18 comes off due to unexpected vibration or impact.

FIG. 3 shows a modification of the apparatus according to the present invention.
This has a groove portion 26 whose cross section is shallow and curved with a gentle slope, and the illustrated example is formed of an arc having substantially the same diameter as the projection 18. An isolation portion 27 is provided between the groove portions 26.
Also in this example, the ratio of the protrusion 18 entering the groove 26 may be about the same as that in the above example. Since other configurations may be the same as those in the above-described example, reference numerals are used, and description thereof is omitted. In addition, 28 shows a non-slip.

Although the illustrated groove 16 has a symmetrical shape, there is no difference in the pushing / pulling operation force. However, by making it asymmetric, the direction toward the contact 11 becomes a gentle slope, and the opposite direction is the same. If the inclination is steeper, it is possible to easily move in the tightening direction but hardly move in the loosening direction. See FIG.

[0020]

Since the present invention is constructed and operates as described above, it is possible to perform the attaching / detaching operation and the operation of increasing / decreasing the tightening force only by pushing and pulling the tightening portion. Since it is easy and does not loosen naturally, the earrings do not come off during wearing, and the effect of high safety is achieved.
