Abstract

PURPOSE: To provide a suspender for spectacle frame which prevents the spectacle frame, suspended from the neck from falling unexpectedly owing to the loosening of a loop into which a temples is inserted by stopping a clamping adjuster from sliding on a fitting ring with a simple constitution without spoiling the outward appearances. CONSTITUTION: An insertion hole into which the fitting ring 7 of a clamping adjuster is inserted is formed out of a group of guide holes which are sectioned in a long circle shape so that the length directions of the cross section shapes of the guide holes cross each other at right angles, and the bundle part 8 of the fitting ring 7 is twisted by 90 deg. in the guide holes. When the clamping adjuster 9 is going to slide, the fitting ring 7 is twisted at another position, so a reaction force is received from the fitting ring 7 to provide braking action.

Description

Detailed Description of the Invention

The present invention relates to a spectacle frame suspending tool for suspending spectacles from a neck when the spectacles are removed.

[0002]

2. Description of the Related Art An eyeglass frame suspending tool is intended to prevent the eyeglasses from dropping due to an inadvertent impact while the eyeglasses are in use, or to suspend the eyeglasses that are frequently worn and removed from the neck to prevent loss. It is used as an accessory for eyeglasses.

Since it is worn with glasses, it is also used as an accessory.

Such a conventional eyeglass frame hanging tool is described, for example, in Japanese Utility Model Laid-Open No. 56-75720.

This will be described with reference to FIGS. 7 and 8. A suspending tool 100 includes a suspending cord 101 and a suspending cord 101.
It includes a set of flexible mounting rings 103 provided at both ends of the mounting ring via a coupling tool 102, and a tightening adjusting tool 105 for pressing and holding a binding portion 103a of the mounting ring 103 in the insertion hole 104.

Both ends of the hanging string 101 are connected to the connecting ring 1.
It is connected to the attachment ring 103 by a metal connector 102 composed of 02a and 102b.

The attachment ring 103 is a binding portion 103a.
Is a cylindrical insertion hole 1 formed in the tightening adjustment tool 105.
By inserting 04, two upper and lower loops 103
It is divided into b and 103c.

The inner diameter of the insertion hole 104 is slightly shorter than the outer diameter of the elastic mounting ring 103 bundled, and the bundling portion 103a of the mounting ring is compressed in the insertion hole 104, and the insertion hole 104 is inserted. Cannot be easily separated from.

As shown in FIG. 8, of the upper and lower loops, the connecting ring 102b is inserted in the upper loop 103b in the figure, and the temple 106 of the spectacle frame is inserted in the lower loop 103c to be connected to each other. ing.

When the spectacle frame suspending tool 100 configured as described above is mounted on the spectacle frame, the temple 106 of the spectacle frame is inserted through the loop 103c of the mounting ring 103 from the handle end, and then the tightening adjusting tool. 1
Loop 10 while sliding 05 toward the temple 106
3c is squeezed to prevent the attachment ring 103 from falling off the temple 106.

[0011]

As described above, in the conventional eyeglass frame suspending tool 100, the tightening adjuster 105 and the mounting ring 103 are configured so that they do not easily slide with each other. Since the insertion hole 104 of the tool 105 has a cylindrical shape, it gradually loosens during use,
There is a problem that the loop 103c through which the temple 106 is inserted expands and the eyeglasses suspended from the neck fall off.

On the other hand, when the eyeglass frame is not attached to the eyeglass frame, the insertion hole 104 of the tightening adjuster 105 has a cylindrical shape, so that the tightening adjuster 105 easily comes out of the mounting ring 103 and is inserted into the insert hole 104 again. There is a problem that it is difficult to insert the attachment ring 103 and only the tightening adjustment tool 105 is lost.

As for the latter problem, as shown in FIG. 9, a swelling portion 103d is formed in the loop 103c so as to be close to the tightening adjuster 105, and the eyeglass frame is suspended to prevent the tightening tool 105 from coming off. Although the tool 101 is known, when it is attached to an eyeglass frame, the bulging portion 103d hits the ear and causes discomfort, and the appearance is also impaired.

There is also known a device in which the binding portion 103a of the mounting ring 103 is wrapped with a wire to bind the tightening adjuster 105, but the size of the loop 103c cannot be adjusted and the workability of assembly is also improved. It is bad and cannot be adopted.

The present invention has been made in order to solve the above-mentioned problems, and the sliding of the tightening adjusting tool with respect to the mounting ring is braked and the temple is inserted through the simple structure without deteriorating the appearance. An object of the present invention is to provide a suspending tool for an eyeglass frame in which a loop does not gradually expand and a tightening adjusting tool does not come out of a mounting ring.

[0016]

In order to solve the above-mentioned problems, the invention of claim 1 comprises a pair of flexible mounting rings provided at both ends of a hanging string via connecting tools. It is equipped with a tightening adjustment tool that presses and holds the binding part of the mounting ring in the insertion hole, insert the temple of the spectacle frame through the loop of the mounting ring, and squeeze the loop while sliding the tightening adjustment tool to fix the mounting ring. In the hanging tool of the eyeglass frame attached to the temple,
The insertion hole is composed of a set of guide holes that communicate with each other in the tightening adjustment tool, and the inner diameter of each guide hole gradually increases from the communication part that presses and holds the binding part of the mounting ring toward the opening. The guide hole is formed so that the cross-sectional shape orthogonal to the axial direction of the guide hole is oval, and the longitudinal direction of the cross-sectional shape of one guide hole is orthogonal to the longitudinal direction of the cross-sectional shape of the other guide hole. It is characterized by that.

Further, the invention of claim 2 is characterized in that the tightening adjusting tool is formed of beads.

Further, the invention of claim 3 is characterized in that the communicating portion is a cylindrical hole.

[0019]

According to the invention of claim 1, the insertion hole is constituted by a guide hole communicating with the communication part in the tightening adjuster, and each guide hole is formed so that the cross-sectional shape orthogonal to the axial direction is oval. In addition, since the longitudinal directions of the cross-sectional shapes of the guide holes are orthogonal to each other, the mounting ring inserted through the cylindrical hole is twisted 90 degrees by the pair of guide holes. When the tightening adjuster tries to slide, another portion is twisted due to the movement of the binding portion, so that a larger sliding operation force is required due to the reaction force from the mounting ring. Therefore, the loop through which the temple is inserted does not gradually expand, and the tightening adjuster does not slip out of the mounting ring.

Further, since both end portions of the insertion hole are guide holes wider than the insertion hole, even if the tightening adjustment tool accidentally comes out of the attachment ring, the attachment ring can be easily inserted into the insertion hole.

According to the invention of claim 2, since the tightening adjusting tool is formed of beads, when the hanging tool of the spectacle frame is used as an accessory, it can be regarded as a part of the accessory, and the overall appearance is There is no loss.

According to the third aspect of the invention, since the communication portion is a cylindrical hole, the bundling portion of the mounting ring is compressed by the cylindrical hole and the sliding of the guide ring together with the mounting ring is braked.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A suspending tool for an eyeglass frame according to an embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a front view of a main part of a suspending tool 1 for an eyeglass frame mounted on a temple 11 of the eyeglass frame, and FIG. 2 is a side view of FIG.

In the figure, reference numeral 2 is a hanging string, in which a narrow nylon string 2a is penetrated through a large number of color-coded colored beads 3.

The hanging string 2 has a length sufficient to suspend the eyeglasses from the neck on the chest, and both ends of the hanging string 2 are fixed to the bottom of the stopper fitting 4 which is a connecting tool so as not to come off.

The stopper fitting 4 is formed by folding a pair of hemispheres connected at the bottom into a spherical shape, and integrally forming a connecting small ring 5 above one hemisphere 4a.

The connecting small ring 5 is further connected to a mounting ring 7 via a metal connecting ring 6.

The attachment ring 7 is made of a flexible and stretchable synthetic rubber, and the binding portion 8 of the attachment ring 7 is inserted into an insertion hole 10 formed in the tightening adjustment tool 9 so that the attachment ring 7 is vertically separated. It is divided into two loops 7a and 7b.

As shown in FIG. 3, this tightening adjustment tool 9
Is obtained by processing a transparent spherical bead, and has an insertion hole 10 formed from the upper side to the lower side so as to penetrate the center thereof.

The insertion hole 10 is a set of guide holes 10b, 10b that communicate with each other at the central communication portion 10a in the tightening adjustment tool 9.
c.

The inner diameter of the communicating portion 10a is slightly smaller than the width of the elastic mounting ring 6 bound together, and the binding portion 8 of the mounting ring is compressed in the insertion hole 10 so that It is not easy to leave.

Each of the guide holes 10b and 10c is provided with a tapered guide surface 10d or 10e whose width gradually increases from the inner diameter of the communicating portion 10a toward the opening, and the cross-sectional shape orthogonal to the axial direction is oval. Has become.

Then, the longitudinal direction of the cross-sectional shape of one guide hole 10b (left-right direction in FIG. 3a) is orthogonal to the longitudinal direction of the cross-sectional shape of the other guide hole 10c (vertical direction in FIG. 3a). Has been formed.

As shown in FIG. 3a, the longitudinal lengths L of the openings 10f and 10g, which appear as oval shapes, are sufficiently longer than the binding width of the mounting ring 6, so that the mounting ring 6 is guided into the guide hole 10b. Even if it is inserted from any of 10c, it can be easily inserted into the insertion hole 10 by being guided by the tapered guide surfaces 10d and 10e.

At this time, since the longitudinal directions of the cross-sectional shapes of the guide holes 10b and 10c are orthogonal to each other, the mounting ring 6 is naturally twisted 90 degrees above and below the cylindrical hole 10a.

FIG. 4 is a perspective view showing a state in which the attachment ring 7 is inserted into the tightening adjuster 9. The upper loop 7a and the lower loop 7b sandwiching the tightening adjuster 9 are
As a result, the surfaces formed by the loops are orthogonal to each other.

As shown in FIGS. 1 and 2, the connecting ring 6 is inserted into the lower loop 7b of the upper and lower loops, and the temple 11 of the spectacle frame is inserted into the upper loop 7a.
Is inserted.

It is desirable that the mounting ring 7 is as small and light as possible so that an excessive load is not applied to the spectacle frame, but from the workability of inserting the insertion hole 10 of the tightening adjustment tool 9, the ring has an extremely small diameter. The thing cannot be adopted. Therefore, the loop 7b below the attachment ring through which the tightening adjuster is inserted has a large diameter to some extent, but the upper and lower loops 7a and 7b have their surfaces formed by the loops orthogonal to each other as described above. The surface formed by the loop 7b is always parallel to the temple 11 (see FIG. 2), and even if the loop 7b has a large diameter, it does not come into contact with the temporal region and cause discomfort.

When the hanging tool 1 for the spectacle frame according to this embodiment is attached to the spectacle frame, the tightening adjuster 9 is slid toward the temple 11 to squeeze the upper loop 7a.

FIG. 5 is a perspective view showing a state in which the suspending tool 1 for the spectacle frame is thus attached to the temple 11.

FIG. 6 shows a tightening adjuster 12 of the second embodiment in which the communication portion 10a of the tightening adjuster 9 of the first embodiment is a cylindrical hole 13a.

The insertion hole 13 is composed of a central cylindrical hole 13a and guide holes 13b and 13c which communicate with each other at both ends of the cylindrical hole 13a.

The inner diameter of the cylindrical hole 13a is slightly shorter than the width of the elastic mounting ring 6 bound together, and the binding portion 8 of the mounting ring is compressed by the cylindrical hole 13a.

Therefore, the mounting ring 7 has a cylindrical hole 13a.
Is compressed by the guide holes 13b and 13c on both sides.
Since it is twisted by 90 degrees, sliding with the tightening adjustment tool 12 is braked.

The conventional tightening adjuster 10 shown in FIG.
Since the insertion hole 104 is a cylindrical hole, the tightening adjustment tool 12 according to the second embodiment can easily be formed by processing both ends of the insertion hole 104 to form the guide holes 13b and 13c.

In the first and second embodiments described above, beads are used for the tightening adjuster 9, but the present invention is not limited to this, and is not limited to a spherical shape, as long as a cylindrical hole and a guide hole can be formed. Other shapes such as a rectangular parallelepiped may be used, and materials such as other metals and synthetic resins may be used.

Also, the hanging string 2 has been described as an example of a thin string and colored beads, but the hanging string 2 is not limited to this and may be a chain or the like as long as it can be connected to the attachment ring 7.

[0049]

As described above, according to the present invention, the tightening adjuster for the mounting ring has a simple structure in which the insertion hole is a guide hole that communicates with the communication portion in the tightening adjuster, and the appearance is not impaired. The sliding of the can be braked, the loop through which the temple is inserted does not gradually expand, and the tightening adjustment tool does not come out of the mounting ring.

Further, since both end portions of the insertion hole are formed as guide holes wider than the insertion hole, the work of inserting the insertion hole can be performed easily, and even if the tightening adjustment tool accidentally comes out of the mounting ring, it can be easily attached to the insertion hole. The ring can be inserted.

Furthermore, since the upper and lower loop forming surfaces of the mounting ring are orthogonal to each other, the surface of the loop on the side where the temple is not inserted is always parallel to the temple, and the loop of the mounting ring hits the temporal region. No discomfort.

According to the invention of claim 2, since the tightening adjusting tool is formed of beads, when the hanging tool of the spectacle frame is used as an accessory, it can be regarded as a part of the accessory, and It does not spoil the appearance. In particular, when the hanging string is formed of beads, the tightening adjuster necessary for the function is seen as a part of the hanging string, and is integrated as a design.

According to the third aspect of the invention, since the communication portion is a cylindrical hole, the bundling portion of the mounting ring is compressed by the cylindrical hole with a predetermined width, and cooperates with the guide hole to surely slide with the mounting ring. Can be braked.
