Description

Glasses with glasses legs with adjustable angles

Technical Field

The invention relates to the field of glasses, in particular to glasses with adjustable angles of glasses legs.

Background

Spectacles are simple optical devices manufactured for correcting eyesight or protecting eyes, and consist of lenses and spectacle frames, and the types of the spectacles are various, for example, sunglasses can resist strong sunlight and are often worn by the public as ornaments. The lenses are primarily functional, while the frame provides not only support, but also decorative purposes. The support of the frame is mainly provided by the legs which are close to the skin of the temple part, and the pile head is not in direct contact with the user. However, because the distance between the head and the temples on the two sides of each person is different, a pair of glasses frames can be too tight or too loose for different persons, and the comfort is affected. And the friction between the glasses legs and the skin is reduced due to sweating when the user wears the glasses for sports, and the glasses can fall off. In the process of frequently taking off and wearing the glasses, the angle between the two temples is increased continuously, so that the glasses need to be held by hands frequently when being worn. The prior art mainly adopts the method of breaking the glasses legs for the conditions so as to adjust the maximum opening of the glasses; or the ear hanging part of the glasses legs is provided with an elastic rope or a clamping foot for positioning; the former adjustment mode can cause the injury to the mirror leg, and the mirror leg can resume original shape in the short time, and the latter adjustment mode then has the aesthetic property poor, carries inconveniently, the bodily form shortcoming such as poor.

Detailed Description

The embodiment of the invention provides a pair of glasses with adjustable supports, which are used in the field of glasses, as shown in figures 1-3, and comprise a set of glasses frames 1, a nose bridge support 2, a fixed support 3 and glasses legs 4, wherein the tail end of the fixed support 3 is provided with an upper cover 31, the front ends of the glasses legs 4 are provided with lower covers 41, the upper cover 31 at the tail end of the fixed support 3 is pivoted with the lower cover 41 at the front ends of the glasses legs 4, a ratchet mechanism 5 is arranged between the upper cover 31 and the lower cover 41, and the glasses legs 4 can only be driven inwards relative to the fixed support 3 under the action of the ratchet mechanism 5.

As shown in fig. 3, the ratchet mechanism 5 includes a button 51, a ratchet 52, a pawl 53, a spline shaft 54, and a spring 55, the ratchet 52 is annularly arranged inside the upper cover 31, the spline shaft 54 is vertically and fixedly arranged at the center of the lower cover 41, the pawl 53 is vertically sleeved on the spline shaft 54, the spring 55 is arranged at the lower side of the pawl 53, the button 51 can move up and down with the pawl 53, and the ratchet 52 and the pawl 53 are engaged with each other. Under the support of the spring 55, the pawl 53 is just meshed with the ratchet wheel 52, the spline shaft 54 is driven to rotate together in the process that the glasses legs 4 horizontally rotate inwards, the spline shaft 54 drives the pawl 53 to rotate together, the pawl 53 is in rotary fit in the ratchet wheel 52, the glasses legs 4 can only rotate inwards in one direction due to the action of the teeth of the pawl 53 and cannot rotate outwards, and the symmetrical side ratchet wheel mechanisms 5 also have the function of adjusting the angles of the glasses legs 4. Because the ratchet wheel 52 and the pawl 53 generate a click matching sound in the meshing process, the hand feeling of angle adjustment of a user is facilitated.

As shown in fig. 3, when the temple 4 needs to be folded or unfolded quickly, the button 51 is only pressed down, the button 51 drives the pawl 53 to move downwards, so that the pawl 53 is completely disengaged from the ratchet 52, thereby realizing the quick folding or unfolding of the temple 4, after the required angle is adjusted, the button 51 is loosened, and under the return action of the spring 55, the pawl 53 returns to the position where the pawl is re-engaged with the ratchet 52, thereby realizing the unidirectional rotation and playing the role of adjusting the angle. To achieve the above cooperation, the lower end cylinder of the button 51 is hollow, the inner diameter is larger than the spline shaft 54, the depth of the lower end cylinder of the button 51 is larger than the thickness of the detent 53, and meanwhile, the cavity depth of the front end of the glasses leg 4 is larger than the thickness of the detent 53.

For the meshing effect of the ratchet wheel 52 and the pawl 53, the pawl 53 is made of engineering plastics in the prior art, and 4 pieces of pawls 53 are arranged in an equal angle distribution.

As shown in fig. 2, the scale 6 is arranged on the surface of the upper cover 31, and the pointer 7 is arranged on the surface of the button 51, so that the angle symmetrical adjustment of the ratchet mechanisms 5 on two sides is facilitated.

As shown in fig. 4, when the ratchet 52 and the pawl 53 of the ratchet mechanism 5 of the left side glasses leg 4 are engaged, the pawl 53 can only rotate anticlockwise, so that inward adjustment is realized; similarly, when the ratchet mechanism 5 of the right side glasses leg 4 is engaged with the ratchet 52 and the pawl 53, the pawl 53 can only rotate clockwise, so that inward adjustment is realized.

As shown in fig. 5, the folding state of the left side temple 4 of the glasses is shown, when the button 51 is pressed, the ratchet 52 and the pawl 53 are disengaged, the left side temple 4 is folded rapidly, and the left and right temples can be folded step by step.

This glasses passes through the cooperation of ratchet 52 pawl 53, and the inboard one-way regulation mirror leg angle of follow prevents the vexation that often drops because of the angle grow between the mirror leg in the glasses use, and is respond well, also can be in the button presses the in-process completely, turns back fast or expand mirror leg, convenient to use.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
