Description

Glasses that can be easily disassembled

The present invention relates to the technical field of glasses.

Known types of glasses are available, such as glasses, reading glasses, sunglasses, and the like.

The commonality of these glasses is nothing more than two lenses and two mirror feet. The lenses are joined together by a bridge, each of which has a connecting arm adjacent thereto that pivotally connects the connecting arm to the temple through a hinge structure.

Conventional hinge structures typically have a shaft and a plurality of pivoting ears that are inserted side by side and side by side and are inserted by the shaft to support movement of the temple relative to the lens between a deployed position and a folded position.

The shafts are mostly screwed and locked into side-by-side pivots. The temples can only be removed from the glasses by loosening the screw. Conversely, if you want to put the temples back, in addition to having all the pivots up and down side by side, you should also align the holes in the center of the pivot ear, and the screws can be smoothly locked. Therefore, the assembly of the hinge structure is quite troublesome, and it consumes too much human resources and wastes time.

Therefore, how to make the glasses easily disassemble the temples has become an urgent problem to be solved in this creation.

In view of this, the case provides a new type of glasses, the main purpose of creation It is: It is easy to assemble and easy to disassemble. It is convenient for the temples to be removed from the glasses and has the function of easy replacement.

Due to the above objectives, the created glasses include two lenses, two mirror legs, two connected frames, and two folding devices, each of which is combined with the frame.

The folding device comprises: a shaft integrally designed with the temple and substantially perpendicular to the length of the temple; a sleeve outside the shaft, the sleeve forming a receiving structure; a supporting member passing through a connecting arm Attaching the support member to the lens or the frame, the support member has a coupling hole and a through hole communicating with each other, allowing the shaft and the sleeve to be simultaneously inserted into the coupling hole of the support member; and a positioning assembly including a latching member The latch member is mounted to the through hole of the support member to reciprocate between an exposed position and a retracted position.

In the exposed position, the latch member partially exposes the coupling hole and the receiving structure of the latching sleeve does not affect the rotation of the temple with the shaft centered on the shaft.

In the retracted position, the sleeve is released from the through hole according to the retracting of the clip, and can be separated from the joint hole along with the shaft, which not only has the function of easy disassembly of the temple, but also has the advantages of convenient assembly and easy replacement. The variability of the different colors of the glasses and the temples.

Wherein, the receiving structure comprises upper and lower conical surfaces and a circumferential surface engaging the lower conical surface, and the gathering of the two conical surfaces is defined as the bottom end of the receiving structure.

The sleeve further includes a top end, a bottom end, and a groove that cuts off the edge of the sleeve to the middle portion and passes through the top end and the bottom end, allowing the shaft to pass through the opening of the groove Into the middle of the sleeve. The outer surface of the shaft forms at least one plane substantially parallel to the wall surface of the recess, and the sleeve can be rotated in the same direction as the shaft but cannot rotate about the shaft.

One end of the shaft has a head for preventing the sleeve from falling, and the other end is connected with a flat portion, and the flat portion is integrally formed with the temple, and the thickness thereof is different to form a drop portion.

In addition, the support member has a sloped surface and a blocking portion for determining the expansion of the temple to a maximum angle, the inclined surface being formed at a falling portion of the support member facing the temple.

The positioning assembly also has a screw that locks into the through hole of the support member and a spring that is inserted into the through hole of the support member and causes the latching member to be in an exposed position. As for the outline of the clip, it is selected from one of a spherical, bullet-shaped, elliptical and cylindrical group.

Figure 1 is a combination of a preferred embodiment of the present invention.

Figure 2 is an exploded view of the folding device.

Figure 3 is a combined cross-sectional view of the folding device.

Figure 4 is a cross-sectional view of the folding device at another angle.

Referring to Fig. 1, the specific configuration of the spectacles 10 is exemplified by two lenses 11, two temples 13, two frames 14, and a two-folding device 20, which are connected together by a nose bridge 12.

Each frame 14 is generally L-shaped and is bonded to the lens 11. The short side of the frame 14 is welded to a substantially U-shaped support arm 16, and the free end of the support arm 16 is pivotally connected to a nose pad 18. In this embodiment, the frame 14 extends a connecting arm 15 along the longitudinal direction, and the connecting arm 15 is connected to the temple 13 through the folding device 20, so that the temple 13 is hung on a user's ear. On the flower. In some embodiments, the connecting arm 15 is separate from the frame 14, and the connecting arm 15 can be secured to the side of the lens 11 by screwing or riveting.

As shown in Figures 2 to 4, the folding device 20 is composed of a shaft 24, a sleeve 30, a support member 40 and a positioning assembly 50.

The shaft 24 is substantially cylindrical, has a flat portion 22 at one end and a head 26 at the other end, and forms a plane 21 on the outer surface of the shaft 24. Therein, the cross section of the head 26 is larger than the cross section of the shaft 24. Since the flat portion 22 and the temple 13 are integrally formed and have different thicknesses to form a drop portion 28, the shaft 24 and the temple 13 are also integrally designed to be substantially perpendicular to the longitudinal direction of the temple 13.

The sleeve 30 has a substantially cylindrical shape, and a recess 33 is formed through the top and bottom ends 31, 32 from the edge of the sleeve 30 to the intermediate portion, so that the top and bottom ends 31, 32 of the sleeve 30 have a close proximity. In the U-shaped area, the sleeve 30 is allowed to fit over the outside of the shaft 24.

Briefly, the shaft 24 enters the intermediate portion of the sleeve 30 through the opening 34 of the recess 33. Under the condition that the bottom end 32 is blocked by the head 26, the sleeve 30 does not fall along the length of the shaft 24 due to gravity. At the same time, the plane 21 is substantially parallel to the wall surface of the recess 33, and the restricting sleeve 30 is rotatable in the same direction as the shaft 24, but is not rotatable about the shaft 24.

In addition, a receiving structure is formed on the outer surface of the sleeve 30. In the figure, the receiving structure includes upper and lower conical surfaces 35, 36 and a circumferential surface 37 that engages the lower conical surface 36. The converging portion 38 defining the conical surfaces 35, 36 is the bottom end, so that the receiving structure is substantially V. Shaped groove.

The support member 40 and the connecting arm 15 are designed to be integrated. The support member 40 has a coupling hole 42 and a through hole 44 communicating with each other, allowing the shaft 24 and the sleeve 30 to be simultaneously inserted into the coupling hole 42 of the support member 40. The support member 40 also has a blocking portion 46 and a slope 48. The blocking portion 46 is formed on the edge of the support member 40, and is located on the support arm 15 The different ends of the piece 40. The inclined surface 48 abuts the blocking portion 46, and the two are designed to be integrated.

The positioning assembly 50 is composed of a screw 52, a spring 54 and a latching member 56. After the spring 54 and the latching member 56 are sequentially inserted into the through hole 44 of the supporting member 40, the supporting member 40 is locked by the screw 52. The through hole 44 is sufficient. Wherein, one end of the spring 54 abuts against the screw 52, and the other end is provided with the required force against the latching member 56, so that the latching member 56 reciprocates between an exposed position and a retracted position, and the exposed position is normal. . In the present embodiment, the latch member 56 has a substantially bullet shape that partially exposes the coupling hole 42 of the support member 40 without leaving the through hole 44.

In the exposed position, the latching member 56 catches the receiving structure of the sleeve 30 (usually the upper and lower conical faces 35, 36) at a portion where the engaging hole 42 is exposed. At this moment, the spring 54 applies a force to the latching member 56 to block the sleeve 30, preventing the shaft 24 and the temple 13 from easily leaving the support member 40.

In the retracted position, the sleeve 30 releases the latching relationship according to the retracting of the latching member 56 into the through hole 44, and can separate from the engaging hole 42 along with the shaft 24, thereby achieving the function of easily disassembling the temple 13 .

When the shaft 24 is inserted into the coupling hole 42 together with the sleeve 30, the sleeve 30 (usually the circumferential surface 37) will urge the latch member 56 to move from the exposed position to the retracted position until the gathering portion 38 of the receiving structure faces the through hole 44. until. At the same time, the latching member 56 is returned from the retracted position to the exposed position, and the receiving structure of the sleeve 30 (usually the upper and lower conical faces 35, 36) is re-locked, and the assembly of the temple 13 and the support member 40 is easily completed. .

Thus, centering on the shaft 24, the temple 13 reciprocates relative to the support member 40 between a deployed position and a retracted position.

The position of the unfolding (such as the solid line in FIG. 4) referred to herein means that the falling portion 28 of the temple 13 faces the inclined surface 48 of the support member 40. At this moment, the blocking portion 46 is located at the mirror Outside the foot 13, it is determined that the temple 13 is deployed to the maximum angle.

The position of the fold (as indicated by the dashed line in Fig. 4) referred to herein means that the temple 13 is swung to a certain angle toward the inside of the support member 40. During the folding, the latching member 56 does not interfere with the circular motion of the upper and lower conical surfaces 35, 36, so that the shaft 24 is rotated at the coupling hole 42 of the support member 40 without being affected by the latching member 56. Therefore, the rotation of the temple 13 is very smooth.
