Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a structure capable of automatically adjusting the elasticity of temples, and a glasses product using the automatic adjustment structure. Background Art

[0002] As we all know, glasses are used to improve vision, protect the eyes, or for decorative purposes. Glasses are typically composed of lenses and a frame. The frame consists of a front frame, a bridge, temples, and temples. The lenses are mounted on the front frame, the bridge is located in the center of the frame, the temples are attached to the left and right sides of the frame, and the temples are hingedly attached to the temples in a retractable and expandable manner. To wear a pair of glasses, place the bridge on your nose and the temples on your ears.

[0003] Ordinary glasses lack a wraparound design, the temples lack specialized elasticity, and the frames are narrow. For those with larger faces, the sides of the head can be squeezed when wearing these glasses. Over time, these temples can create indentations, causing discomfort and pressure. Furthermore, as the temples are stretched by the head, the inelastic temples can cause the front frame to bend backwards at the center bridge, causing changes in the lens fitting data (pupillary distance), which can affect the wearer's eye health.

[0004] In view of this, the inventor, relying on his professional technical level and accumulated rich experience in long-term research, design and manufacturing, as well as his familiarity with product structure and performance, has developed a new structure suitable for temples after repeated research, design, experimentation, modification and testing. Utility Model Content

[0005] The purpose of the utility model is to provide an elastic automatic adjustment structure for the temples, so that the angle of the temples can not only be automatically adjusted when unfolded, but also can prevent excessive opening, so that the angle can be opened wider within a certain range to adapt to users with different head circumferences, improve wearing comfort, and ensure the stability of the front frame.

[0006] The purpose of the present utility model is to provide glasses using the above elastic automatic adjustment structure.

[0007] In order to achieve the above purpose, the solution of the utility model is:

[0008] The invention relates to an elastic automatic adjustment structure for a temple. A hinge portion and a limit block are formed at the fork of the front section of the temple. The front end of the hinge portion is hinged to the rear end of the stud. The hinge portion forms a group of inner grooves and a group of outer grooves on the inner and outer sides, respectively. The inner and outer grooves are arranged in an interlaced manner, so that an elastic corrugated section is formed on the hinge portion. The elastic corrugated section has a rectangular wave shape when viewed from above. The limit block extends from the back to the front at the fork of the temple. The limit block is located outside the elastic corrugated section. The front end of the limit block is suspended in the air. A movable gap is retained between the limit block and the elastic corrugated section in normal state. When the temple is extended outward, the front end of the limit block gradually approaches the elastic corrugated section or abuts against the elastic corrugated section to limit the position.

[0009] The limit blocking piece blocks the outer section groove on the outer side of the elastic corrugated section.

[0010] There are three to four inner and outer grooves respectively.

[0011] The inner and outer grooves are arranged in a staggered manner from front to back, with the inner grooves in front and the outer grooves in the back.

[0012] The depth of the inner groove is shallower than that of the outer groove, so that the restoring force of the temple is greater and the temple can better embrace the head.

[0013] The position-limiting blocking piece extends forward in a smooth transition at the bifurcation of the temple, and the hinge portion protrudes inward at the bifurcation of the temple.

[0014] A pair of glasses, composed of lenses and a frame; the frame includes a front frame, a middle beam, a stud and temples; the lenses are mounted on the front frame, the middle beam is located in the middle of the front frame, and the front ends of the studs are mounted on the left and right sides of the front frame; the temples have an elastic automatic adjustment structure, and the front end of the temples is bifurcated to form a hinge part and a limit block; the front end of the hinge part is hinged to the rear end of the stud, so that the temples are hinged and mounted on the stud in an expandable or retractable manner, and the hinge part forms a set of inner grooves on the inner side and the outer side respectively and a group of external grooves, and the internal grooves and the external grooves are arranged in an interlaced manner, so that an elastic corrugated section is formed on the hinge portion, and the elastic corrugated section is in the shape of a rectangular wave when viewed from above; the limit block extends from the back to the front at the bifurcation of the temple, the limit block is located on the outside of the elastic corrugated section, and the front end of the limit block is suspended in the air. A movable gap is retained between the limit block and the elastic corrugated section in normal state, and when the temple is expanded outward, the front end of the limit block gradually approaches the elastic corrugated section or abuts against the elastic corrugated section to limit the position.

[0015] The frame is a half-frame frame or a full-frame frame, the front frame of the frame is a half-frame frame or a full-frame frame, the lenses are installed in the half-frame frame or the full-frame frame, and the pile heads are arranged on the left and right sides of the half-frame frame or the full-frame frame.

[0016] The frame is a frameless frame, the front frame of which is composed of a center beam and a pile head, the lenses are installed between the center beam and the pile head, and the pile heads are arranged on the left and right sides of the frameless frame.

[0017] After adopting the above scheme, the utility model forks at the front section of the temple to form a hinge part and a limit block, and forms an elastic corrugated section on the hinge part. The rectangular wave shape of the elastic corrugated section has both elastic properties and a certain strength than the ordinary water corrugated shape, which can ensure the supporting performance of the temple, so that when the temple is opened, the rectangular wave shape of the elastic corrugated section can bend outward to provide space for the temple to elastically expand, increase the opening angle of the temple, and realize automatic adjustment of the expansion angle of the temple. As a result, the pressure of the glasses on the contact surface of the head is greatly reduced, the comfort and experience of wearing glasses are improved, and it is suitable for users with various head circumferences, especially people with relatively wide heads and faces who need to wear glasses.

[0018] At the same time, the utility model can assist in optimizing the clamping force of the temples by limiting the top position of the elastic corrugated section on the outside of the elastic corrugated section through the limit block, limit the maximum bending degree of the elastic corrugated section, prevent the deformation problem of the temples after infinite pulling and magnification, and enable the unfolding angle of the temples to be controlled within a certain range to prevent the temples from opening excessively.

[0019] Moreover, the present invention concentrates the elasticity of the glasses on the elastic corrugated sections of the temples. When the temples are opened at a large angle, only the elastic corrugated sections are elastically deformed and deflected. The limit blocks also limit the unfolding angle to a greater opening within a certain range, while the front frame does not deform. This ensures the stability of the front frame and lenses of the glasses, and effectively avoids the phenomenon in the prior art of changes in lens fitting data (pupillary distance) caused by reverse bending deformation of the front frame of the glasses, thereby affecting the user's eye health.

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.

[0035] It should be noted that the terms upper, lower, inner, outer, first, second, etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the technical features indicated, unless otherwise clearly and specifically defined.

[0036] like Figures 1 to 8As shown, the present invention discloses an elastic, automatically adjustable temple structure suitable for eyeglasses. The basic structure of eyeglasses consists of a lens 10 and a frame. The frame includes a front frame 20, a center beam (a conventional component not shown), a stud 30, and temples 40. The lens 10 is mounted on the front frame 20, with the center beam located in the center of the front frame 20 and the front ends of the studs 30 mounted on the left and right sides of the front frame 20.

[0037] The key point of the present invention is that the front section of the temple 40 is bifurcated to form a hinge portion 41 and a limit block 42 .

[0038] Among them, the front end of the hinged part 41 is hinged to the rear end of the pile head 30, so that the temple 40 is hingedly installed on the pile head 30 in an expandable or foldable manner, and the hinged part 41 forms a group of inner grooves 411 and a group of outer grooves 412 on the inner side and the outer side respectively, and the inner grooves 411 and the outer grooves 412 are arranged in an interlaced manner, so that an elastic corrugated section 410 is formed on the hinged part 41, and the elastic corrugated section 410 is in the shape of a rectangular wave when viewed from above.

[0039] The limiting block piece 42 extends from the back to the front at the bifurcation of the temple 40, and is located on the outside of the elastic corrugated section 410. The front end of the limiting block piece 42 is suspended in the air, and a movable gap d is retained between the limiting block piece 42 and the elastic corrugated section 410 in a normal state. When the temple 40 is expanded outward, the front end of the limiting block piece 42 gradually approaches the elastic corrugated section 410, and finally the front end of the limiting block piece 42 can be against the elastic corrugated section 410 (such as Figure 6 and Figure 7 As shown), the elastic corrugated section 410 is limited in bending outwards, thereby achieving the purpose of limiting.

[0040] In this way, when in use, the special rectangular wave shape design of the elastic corrugated section 410 of the utility model has both elastic properties and a certain strength compared to the ordinary water corrugated shape, which can ensure the supporting performance of the temple 40, so that when the temple 40 is opened, the rectangular wave shape of the elastic corrugated section 410 bends outward to provide space for the temple 40 to elastically expand, thereby increasing the opening angle of the temple 40 and realizing automatic adjustment of the expansion angle of the temple 40. As a result, the pressure of the glasses on the contact surface of the head is greatly reduced, and the comfort and experience of wearing glasses are improved, so that the utility model can adapt to users with various head circumferences, especially people with relatively wide heads and faces who need to wear glasses. At the same time, during use, the utility model assists in optimizing the clamping force of the temple 40 by limiting the top position of the elastic corrugated section 410 on the outside of the elastic corrugated section 410 through the limiting baffle 42, limits the maximum bending degree of the elastic corrugated section 410, and prevents the deformation problem of the temple 40 after infinite pulling and magnification, so that the expansion angle of the temple 40 can be controlled within a certain range, thereby effectively preventing the temple 40 from opening excessively and further improving the embracing effect of the temple 40. In addition, the present invention concentrates the elasticity of the glasses on the elastic corrugated section 410 of the temple 40. When the temple 40 is opened at a large angle, only the elastic corrugated section 410 undergoes elastic deformation and deflection. The limit block 42 also limits the temple 40 to be able to open further only within a certain range. The limit block 42 is not deformed and will not affect the appearance of the temple 40. Moreover, the front frame 20 is also not deformed, thus ensuring the stability of the front frame 20 and the lens 10 of the glasses, and effectively avoiding changes in the lens fitting data (pupillary distance) caused by the reverse bending deformation of the front frame 20 of the glasses, thereby affecting the user's eye health.

[0041] The optimized design of the present invention is that the limit block 42 is on the outside of the elastic corrugated section 410, completely blocking the outer groove 412. In this way, it can not only better support the elastic corrugated section 410, limit its bending amplitude, and control the temple 40 from excessive expansion, but also make the overall outer side of the temple 40 more beautiful.

[0042] The optimized design of the present invention is that there are three to four inner grooves 411 and outer grooves 412, respectively. This number not only ensures sufficient flexibility for the temple 40, but also makes the structure relatively simple and easier to manufacture. Furthermore, the inner grooves 411 and outer grooves 412 are preferably arranged in a staggered arrangement from front to back, with the inner grooves 411 in front and the outer grooves 412 in the back. The inner grooves 411 are shallower than the outer grooves 412, allowing the elastic corrugated sections 410 to bend outward more easily, thus increasing the restoring force of the temple 40 and allowing the temple 40 to better embrace the head.

[0043] The optimized design of the present invention is that the limit block 42 smoothly transitions and extends forward at the bifurcation of the temple 40, making the appearance of the temple 40 smoother and more beautiful. The hinged portion 41 protrudes inward at the bifurcation of the temple 40, so that an angle a is formed between the hinged portion 41 and the rear section of the temple 40, and the embracing effect is also better.

[0044] The present invention also discloses a pair of glasses utilizing the aforementioned automatic elastic adjustment structure for temples. The glasses are composed of lenses 10 and a frame. The frame includes a front frame 20, a center beam (a conventional component not shown), a post 30, and temples 40. The lenses 10 are mounted on the front frame 20, with the center beam located in the center of the front frame 20 and the front ends of the post 30 mounted on the left and right sides of the front frame 20. As previously described, the temples 40 have an automatic elastic adjustment structure.

[0045] The key to the present invention lies in the bifurcation of the front end of the temple 40 to form a hinged portion 41 and a stopper 42. The front end of the hinged portion 41 is hingedly connected to the rear end of the base 30, allowing the temple 40 to be hingedly mounted on the base 30 in an expandable or retractable manner. The hinged portion 41 forms a set of inner grooves 411 and a set of outer grooves 412 on the inner and outer sides, respectively. The inner and outer grooves 411 and 412 are arranged in an interlaced manner, forming an elastic corrugated section 410 on the hinged portion 41. The elastic corrugated section 410 has a rectangular wave shape when viewed from above. The limit block 42 extends from the back to the front at the bifurcation of the temple 40. The limit block 42 is located on the outside of the elastic corrugated section 410. The front end of the limit block 42 is suspended in the air. A movable gap d is retained between the limit block 42 and the elastic corrugated section 410 under normal conditions. When the temple 40 is expanded outward, the front end of the limit block 42 gradually approaches the elastic corrugated section 410 and can eventually rest against the elastic corrugated section 410, so that the elastic corrugated section 410 is restricted from bending outward, thereby achieving the purpose of limiting.

[0046] The present invention, due to the special rectangular wave shape of the elastic corrugated section 410, has both elasticity and a certain strength, ensuring the support performance of the temple 40. When the temple 40 is opened, the rectangular wave shape of the elastic corrugated section 410 bends outward, providing space for the temple 40 to elastically expand, increasing the opening angle of the temple 40, and realizing automatic adjustment of the expansion angle of the temple 40, significantly reducing the pressure of the contact surface of the glasses on the head, and improving the comfort and experience of wearing glasses. At the same time, the present invention uses the limit block 42 on the outside of the elastic corrugated section 410 to limit the elastic corrugated section 410, thereby limiting the maximum bending degree of the elastic corrugated section 410, effectively preventing the temple 40 from excessively opening, and further improving the hugging effect of the temple 40.

[0047] The frame of the present invention can be a half-frame or full-frame frame. The figure shows a half-frame frame, in which the front frame 20 is a half-frame frame, the lens 10 is installed in the half-frame frame, and the pile heads 30 are arranged on the left and right sides of the half-frame frame.

[0048] The frame described in the present invention can also be a frameless frame, which is not shown in the figure. In this case, the front frame of the frame is composed of a center beam and a pile head to form a frameless frame, and the lenses are installed between the center beam and the pile head, and the pile heads are set on the left and right sides of the frameless frame.

[0049] The present invention concentrates the elasticity of the glasses on the elastic corrugated section 410 of the temple 40. When the temple 40 is opened at a large angle, only the elastic corrugated section 410 is elastically deformed and deflected. The limit block 42 limits the temple 40 from being opened further to a certain range. The limit block 42 does not deform and does not affect the appearance of the temple 40. The front frame 20 also does not deform, ensuring the stability of the front frame 20 and the lens 10 of the glasses, and effectively avoiding changes in the lens fitting data (pupillary distance) caused by the reverse bending deformation of the front frame 20 of the glasses, thereby affecting the user's eye health.

[0050] The above description is only an example of the implementation of the present invention and does not limit the scope of protection of the present invention. It should be noted that after reading this specification, equivalent changes made by those skilled in the art based on the design ideas of this case will fall within the scope of protection of this case.
