Abstract
Description
Technical Field
[0001] The utility model relates to the field of glasses, in particular to an angle-adjustable temple and glasses. Background Art
[0002] The spectacle frame is an important part of glasses. The spectacle frame mainly includes a spectacle frame and temples. The spectacle frame and the temples are generally hinged together. When the temples are unfolded, the temples hook on the ears to achieve fixation; when the temples are folded, the temples are basically attached to the spectacle frame, reducing the overall occupied space of the glasses and facilitating the storage of the glasses.
[0003] The temple itself is generally an integral structure. After being assembled with the spectacle frame, it generally only has one mechanical degree of freedom, that is, the rotational degree of freedom within a certain angle around the hinge.
[0004] In some scenarios, such as when reading a book or newspaper with a downward view angle, some glasses wearers are used to pulling down the glasses, that is, only hanging the glasses lightly on the nose while making the front of the lens face downward. This is because usually the eyesight is mostly horizontal, while when reading a book or newspaper, the eyesight is obliquely downward. After such adjustment, the position and angle of the lens are more suitable for the downward eyesight. However, this habit requires the wearer to fiddle with the glasses every time, and in this scenario, the glasses are also likely to be worn insecurely. Content of the Utility Model
[0005] The problem to be solved by the utility model is to provide an angle-adjustable temple and glasses, which change the common integral temple into a relatively movable front temple and rear temple. By adjusting the included angle between the front temple and the rear temple, the habits of glasses wearers in some usage scenarios can be satisfied.
[0006] To solve the above problems, the utility model provides an angle-adjustable temple and glasses. To achieve the above object, the technical solution adopted by the utility model to solve its technical problems is:
[0007] An angle-adjustable temple, comprising: a front temple capable of being assembled with a spectacle frame; a rear temple movably assembled with the front temple through a rotating shaft; a positioning mechanism including a compression spring and a positioning bead located at the junction of the front temple and the rear temple, one end of the compression spring being in contact with the positioning bead; the opposite surfaces of the front temple and the rear temple are respectively provided with a blind hole and a plurality of pits; the compression spring is located in the blind hole; the positioning bead is selectively in contact with the pits, and the connecting direction between different pits is perpendicular to the axis direction of the rotating shaft.
[0008] The beneficial effects of adopting the above technical solution are as follows: First, in this technical solution, the common one-piece temple is changed into a relatively movable front temple and a rear temple. The front temple and the rear temple have the freedom to adjust the included angle with each other, and correspondingly, it is convenient to adjust the included angle of the frame and lens connected to the front temple relative to the rear temple, thus meeting the wearing habits of wearers in some usage scenarios of glasses. That is, for example, when looking down at a book or newspaper. By bending the relatively straight front temple and rear temple, the lens is oriented obliquely downward, which can meet the usage habits of the wearer, and at the same time, the state of the temple and the glasses is relatively stable.
[0009] Secondly, the positioning bead, compression spring, and positioning pit are used to temporarily position the locking position of the front temple and the rear temple, ensuring that the front temple and the rear temple are at the preset included angle each time. The combination form of the positioning bead, compression spring, and positioning pit achieves a balance between adjustment and locking. The front temple and the rear temple need to withstand a certain external force to change the included angle, and will not be changed under a small external force.
[0010] Finally, the rotating shaft allows only one degree of freedom of rotation around the rotating shaft between the front temple and the rear temple, and the positions of several concave pits are used to temporarily lock the front temple and the rear temple at a certain rotation position.
[0011] As a further improvement of the present utility model, the concave pit is located on the front temple, and the blind hole is located on the rear temple.
[0012] As a further improvement of the present utility model, the number of concave pits is two.
[0013] The beneficial effects of adopting the above technical solution are as follows: The two concave pits mean that there are two extreme position states between the front temple and the rear temple.
[0014] As a further improvement of the present utility model, the positioning bead is a sphere, the diameter of the positioning bead is greater than the diameter of the compression spring, and the inner diameter of the blind hole is greater than the diameter of the positioning bead.
[0015] The beneficial effects of adopting the above technical solution are as follows: The compression spring provides the elastic force for the positioning bead to move towards the concave pit in the clockwise direction, and the blind hole provides positioning and linear guiding functions for the compression spring and the positioning post.
[0016] As a further improvement of the present utility model, the compression spring is surrounded by a hollow cavity, the positioning bead is fixed with a limiting rod, and the limiting rod is inserted into the hollow cavity of the compression spring.
[0017] The beneficial effects of adopting the above technical solution are as follows: With the limiting rod, it is more difficult for the positioning bead and the compression spring to become loose.
[0018] As a further improvement of the present utility model, the inner wall of the concave pit is a concave curved surface, and the space surrounded by each concave pit is a spherical segment.
[0019] The beneficial effects of adopting the above technical solution are as follows: The surface of the positioning bead is a convex curved surface. After the positioning bead comes into contact with the concave pit, there is a sufficient contact area, ensuring the stability of the contact positioning.
[0020] As a further improvement of the present utility model, the front temple has a rear extension piece extending towards the rear temple, the rear temple has two front extension pieces extending towards the front temple, and the rear extension piece is located between the two front extension pieces; the concave pit is located at the top of the rear extension piece; the rotation axis is located at the root of the rear extension piece.
[0021] The beneficial effects of adopting the above technical solution are as follows: The front extension piece and the rear extension piece are staggered with each other, playing a role in limiting and protecting the junction of the front temple and the rear temple, preventing the front temple and the rear temple from tilting in other directions, and avoiding deformation and damage of the front temple and the rear temple.
[0022] As a further improvement of the present utility model, the length of the rear temple is greater than the length of the front temple.
[0023] The beneficial effects of adopting the above technical solution are as follows: The long length of the rear temple is convenient for arranging blind holes and also for the rear temple to contact the wearer's ear.
[0024] A pair of glasses includes the angle-adjustable temple mentioned above.
[0025] As a further improvement of the present utility model, the spectacle frame is movably assembled with the front temple through a rotation axis; the lens is located in the spectacle frame; the axis of the rotation axis and the axis of the rotation shaft are skew perpendicular to each other.
[0026] The beneficial effects of adopting the above technical solution are as follows: The rotation axis realizes the folding and storage of the temple and the spectacle frame. The rotation shaft plays a role in adjusting the front temple and the rear temple. The respective orientation relationships of the rotation axis and the rotation shaft illustrate that when the glasses are worn, the front temple and the rear temple basically swing in the vertical plane, thereby realizing the up and down adjustment of the lens orientation.

[0035] The following will further elaborate on the content of the present utility model in conjunction with specific embodiments:
[0036] To achieve the object of the present utility model, an angle-adjustable temple includes: a front temple 1 that can be assembled with the spectacle frame 8; a rear temple 2 that is movably assembled with the front temple 1 through a rotating shaft 3; a positioning mechanism including a compression spring 4 and a positioning bead 5 located at the junction of the front temple 1 and the rear temple 2, with one end of the compression spring 4 in contact with the positioning bead 5; the opposite surfaces of the front temple 1 and the rear temple 2 are respectively provided with blind holes 22 and a plurality of concave pits; the compression spring 4 is located in the blind hole 22; the positioning bead 5 selectively contacts the concave pits, and the connecting direction between different concave pits is perpendicular to the axis direction of the rotating shaft 3.
[0037] The rear temple 2 can contact the wearer's ear.
[0038] The beneficial effects of adopting the above technical solution are as follows: First, this technical solution changes the common integrated temple into a relatively movable front temple and rear temple. The front temple and the rear temple have the freedom to adjust the included angle with each other, which correspondingly facilitates the included angle between the frame and lens connected to the front temple and the rear temple, thus meeting the wearing habits of wearers in some usage scenarios of glasses. That is, for example, when looking down at books or newspapers. By bending the relatively straight front temple and rear temple, the lens is oriented obliquely downward, which can meet the usage habits of the wearer, and at the same time, the state of the temple and the glasses is relatively stable. Second, the positioning bead, compression spring, and positioning pit are used to temporarily position the locking position of the front temple and the rear temple, ensuring that the front temple and the rear temple are at the preset included angle each time. The combination form of the positioning bead, compression spring, and positioning pit achieves a balance between adjustment and locking. The front temple and the rear temple need to withstand a certain external force to change the included angle, and will not be changed under a small external force. Finally, the rotating shaft allows only one degree of freedom of rotation around the rotating shaft between the front temple and the rear temple, and the positions of several pits are to temporarily lock the front temple and the rear temple at a certain rotation position.
[0039] In some other embodiments of the present invention, the pit is located on the front temple 1, and the blind hole 22 is located on the rear temple 2.
[0040] In some other embodiments of the present invention, the number of pits is two.
[0041] The pit may include an upper pit 12 and a lower pit 13. The upper pit 12 and the lower pit 13 are in different positions, and the shapes and sizes of the spaces surrounded by the upper pit 12 and the lower pit 13 are the same.
[0042] The upper pit 12 and the lower pit 13 enable the front temple 1 and the rear temple 2 to have two extreme positions. One is that the longitudinal directions of the front temple 1 and the rear temple 2 coincide with each other, that is, the included angle at the junction is 180°, and the other is that the included angle between the longitudinal directions of the front temple 1 and the rear temple 2 is 171°.
[0043] The beneficial effects of adopting the above technical solution are: The two pits mean that there are two extreme position states between the front temple and the rear temple.
[0044] In some other embodiments of the present invention, the positioning bead 5 is a sphere, the diameter of the positioning bead 5 is greater than the diameter of the compression spring 4, and the inner diameter of the blind hole 22 is greater than the diameter of the positioning bead 5.
[0045] In the uncompressed state of the compression spring 4, the sum of the axial length of the compression spring 4 and the diameter of the positioning bead 5 is greater than the depth of the blind hole 22.
[0046] The beneficial effects of adopting the above technical solution are: The compression spring provides an elastic force for the positioning bead to move clockwise towards the pit, and the blind hole provides positioning and linear guiding functions for the compression spring and the positioning post.
[0047] In some other embodiments of the present utility model, the compression spring 4 encloses a hollow cavity, the positioning bead 5 is fixed with a limiting rod, and the limiting rod is inserted into the hollow cavity of the compression spring 4.
[0048] The compression spring 4 is a spiral compression spring, which naturally forms a hollow cavity.
[0049] The beneficial effect of adopting the above technical solution is that after the limiting rod is provided, it is more difficult for the positioning bead and the compression spring to become loose.
[0050] In some other embodiments of the present utility model, the inner wall of the concave pit is a concave curved surface, and the space enclosed by each concave pit is a spherical segment.
[0051] The space enclosed by each concave pit can be a space equal to a hemisphere or a space smaller than a hemisphere.
[0052] The diameter corresponding to the inner wall of the concave pit is not less than the diameter of the positioning bead 5.
[0053] The opening edge of the concave pit can also be transitioned through an external rounded corner.
[0054] The beneficial effect of adopting the above technical solution is that the surface of the positioning bead is a convex curved surface, and after the positioning contact between the positioning bead and the concave pit, there is a sufficient contact area to ensure the stability of the contact positioning.
[0055] As Figure 1 shown, in some other embodiments of the present utility model, the front temple 1 has a rear extension piece 11 extending towards the rear temple 2, the rear temple 2 has two front extension pieces 21 extending towards the front temple 1, and the rear extension piece 11 is located between the two front extension pieces 21; the concave pit is located at the top of the rear extension piece 11; the rotating shaft 3 is located at the root of the rear extension piece 11.
[0056] The beneficial effect of adopting the above technical solution is that the front extension piece and the rear extension piece are staggered with each other, which plays a role in limiting and protecting the junction of the front temple and the rear temple, avoiding the front temple and the rear temple from skewing in other directions, and avoiding deformation damage of the front temple and the rear temple.
[0057] In some other embodiments of the present utility model, the length of the rear temple 2 is greater than the length of the front temple 1.
[0058] The beneficial effect of adopting the above technical solution is that the long length of the rear temple is convenient for arranging blind holes and is also convenient for the rear temple to contact the wearer's ear.
[0059] A pair of glasses includes the angle-adjustable temples mentioned above. A front temple 1 and a rear temple 2 combined form a complete temple. The glasses include two temples, that is, two front temples 1 and two rear temples 2.
[0060] In some other embodiments of the present utility model, the spectacle frame 8 is movably assembled with the front temple 1 through a rotary shaft 7; the lens 6 is located in the spectacle frame 8; the axis of the rotary shaft 7 and the axis of the rotation axis 3 are skew perpendicular to each other.
[0061] The rotation axis 3 and the rotary shaft 7 are essentially the same, both are movably hinged, and only one mechanical degree of freedom for relative rotation is retained between the two components they connect.
[0062] The beneficial effects of adopting the above technical solutions are as follows: the rotary shaft realizes the folding and storage of the temple and the spectacle frame. The rotation axis plays a role in adjusting the front temple and the rear temple. The respective orientation relationships of the rotary shaft and the rotation axis illustrate that when the glasses are worn, the front temple and the rear temple basically swing in the vertical plane, so as to realize the up and down adjustment of the lens orientation.
[0063] Regardless of the change in the angle between the front temple 1 and the rear temple 2, this is to make the included angle between the lens 6 and the line of sight passing through the lens 6 closer to 90°.
[0064] For clearly showing the structural principle, Figures 1 to 3 At the same time, it is also a partial sectional view. Figure 6 Compared with Figure 5 , Figure 5 is the use state when the wearer's line of sight is horizontal. At this time, the front temple 1 and the rear temple 2 coincide on the same straight line. Figure 6 is the use state when the wearer's line of sight is downward. At this time, the front temple 1 and the rear temple 2 form a certain obtuse angle. It can be seen that Figure 6 the front surface of the lens 6 in Figure 5 is more oriented obliquely downward than the front surface of the lens in
[0065] The above embodiments are only used to illustrate the technical concept and features of the present utility model. The purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it. It should not be used to limit the protection scope of the present utility model.
