Abstract
Description
Technical Field
[0001] This utility model relates to a frame and temple assembly structure that allows the second locking tooth and the first locking tooth to pivot smoothly relative to each other by retracting and compressing the second elastic slot and the first elastic slot. Background Technology
[0002] Currently, the connection between the frame and temples of most eyeglasses, whether using metal hinges or plastic inserts, has the drawback of the hinges or inserts gradually loosening, causing the temples to wobble. Moreover, when the glasses are unfolded, they tend to slip off automatically, making them difficult to securely wear.
[0003] There is a Chinese utility model patent application, CN219143217, published on June 6, 2023, entitled "A Novel Glasses with a Gear-Driven Rhythmic Rotating Slingshot Hinge." It discloses that the glasses include a frame, a headstock, temples, and a slingshot hinge. The slingshot hinge includes a gear positioning part formed at the end of the headstock, a toothed insert that meshes with the gear positioning part, a socket formed at the end of the temples to allow the toothed insert to pass through and move axially, and a spring disposed in the socket to allow the toothed insert to move axially. One end of the toothed insert has a toothed portion that meshes with the gear positioning part, and the other end has a insert portion that passes through the socket. The gear positioning part of the pin head rotates around the hinge axis through meshing with the toothed insert, and the toothed insert can reciprocate axially under the action of the spring in the insertion hole of the temple, so that the temple can rotate elastically relative to the pin head in a rhythmic and multi-angle manner. This avoids the collision between the temple and the pin head under the action of inertial force in ordinary slingshot hinges, and improves the durability of the slingshot hinge and the glasses.
[0004] While the prior art patent allows the toothed part of the toothed insert to engage with the gear positioning part on the post head to fix the temple of the eyeglasses to the frame, ensuring a secure and stable position, the pivoting motion of the toothed insert relative to the gear positioning part requires the extension and contraction of a spring to achieve the elastic pivoting effect. This necessitates the addition of spring components and a spring-accommodating insertion hole, resulting in increased component complexity, structural inconsistencies, and manufacturing difficulties.
[0005] Another patent application, No. TWM434225, published in Taiwan on July 21, 2012, describes a "pivotal structure for eyeglasses temples." It discloses an eyeglass frame comprising a frame, two temples, and two lenses. The temples are pivotally connected to both sides of the frame, which are connected to the temples by screws. Two pivoting devices are used to connect the frame and the temples. The pivoting device includes a ratchet and a locking block. The ratchet is positioned on both sides of the frame and consists of several protruding locking teeth. The locking block is attached to the front end of the temples and is pressed by an elastic element. The locking block can engage with the ratchet. Therefore, when the temples are opened or closed, the locking block can engage with the ratchet or disengage to allow for segmented opening and closing, preventing deformation and adapting to various face shapes.
[0006] The previous patent also required the extension and contraction of an elastic element (spring) to achieve the effect of elastic pivoting and swinging. Since it required the addition of an elastic element component and a positioning groove structure to accommodate the elastic element, it also had the disadvantages of increased components, complex structure and difficulty in manufacturing, and therefore was not ideal in use. Utility Model Content
[0007] Therefore, considering the aforementioned drawbacks of the current eyeglass frame and temple connection structure, the purpose of this invention is to provide an eyeglass frame and temple connection structure.
[0008] This utility model provides a frame and temple combination structure for eyeglasses, characterized in that it includes:
[0009] A frame with at least one first pivot part on each side, the first pivot part having a recessed hole, the periphery of the first pivot part having a plurality of first locking teeth, the first pivot part having a first elastic groove near the position of the first locking teeth, and the inner side of the first pivot part having a gradually tapering slope at the point where the first locking teeth extend toward the recessed hole.
[0010] Two temples, movably pivotally connected to the first pivot portion on both sides of the frame. At least one end of each temple has a second pivot portion, and the second pivot portion has a pin that is correspondingly embedded in the recessed hole for limiting and fixing. The second pivot portion has a plurality of second locking teeth protruding at the position corresponding to the first locking teeth. The second locking teeth mesh with the first locking teeth and can be elastically pivoted relative to each other. One end of the temple has a second elastic slot near the side of the second locking teeth. When the second locking teeth and the first locking teeth pivot relative to each other and their tips intersect, the second elastic slot and the first elastic slot can be retracted and compressed respectively, so that the second locking teeth and the first locking teeth can smoothly pivot relative to each other.
[0011] The eyeglasses frame and temples are combined in such a structure that: two first pivot parts are respectively provided on both sides of the frame, one above the other, and the two first pivot parts are respectively provided with the recessed holes on the upper and lower sides.
[0012] The frame and temples of the glasses are combined in such a structure that the periphery of the two first pivot joints is provided with the first locking teeth.
[0013] The eyeglasses frame and temples are combined in a structure in which the two first pivot points are respectively provided with the first elastic slot.
[0014] The eyeglasses frame and temples are combined in a structure in which the inclined surfaces are provided on the opposite inner sides of the two first pivot joints.
[0015] The eyeglasses frame and temples are combined in the following manner: one end of the temples is provided with two second pivot parts that are opposite each other, and the two second pivot parts are provided with the inserts corresponding to each other, and the two inserts are correspondingly embedded in the two holes for limiting and fixing.
[0016] The eyeglasses frame and temples are combined in such a structure that: the two second pivot parts are respectively provided with second locking teeth at the positions corresponding to the first locking teeth.
[0017] The eyeglasses frame and temples are combined in a structure in which the first elastic slot is located between the recess and the first locking tooth.
[0018] The above-mentioned technical features have the following advantages:
[0019] 1. By means of the intermeshing and transmission of the second locking tooth and the first locking tooth, the temple can be reliably pivoted relative to the frame, and the two temples can be smoothly pivoted, unfolded or retracted and positioned relative to the frame.
[0020] 2. When the second locking tooth and the first locking tooth pivot relative to each other and their tips intersect, the second elastic slot and the first elastic slot can be retracted and compressed respectively, so as to facilitate the smooth relative pivoting of the second locking tooth and the first locking tooth without being obstructed, and without causing the second locking tooth and the first locking tooth to malfunction due to wear, thus extending their service life.
[0021] 3. The two first pivot joints have tapered inclined surfaces on their inner sides, which allow the two inserts to be elastically compressed relative to each other when passing through the two inclined surfaces. After they are separated from the inclined surfaces, they can be elastically opened up so that the inserts can be elastically locked into the insertion holes, thereby facilitating assembly and preventing them from falling off.
[0022] 4. Furthermore, the temple posts can be flexibly engaged in the recessed holes of the frame, ensuring a tight fit that is not easily loosened, thus overcoming the lack of durability of conventional metal screws. Assembly and disassembly are also quite easy. Attached Figure Description

Furthermore, "first," "second," and "third," etc., only indicate the distinction between components with the same attributes and do not indicate a necessary assembly order or quantity.
[0033] Please see Figure 1 , Figure 2 and Figure 3 As shown, this embodiment of the utility model provides a frame and temple combination structure for eyeglasses, comprising: a frame 1 and temples 2, wherein:
[0034] The frame 1 has two first pivot portions 11 on each side, one above the other, each with a corresponding recessed hole 12. A plurality of first locking teeth 13 are provided around the periphery of each first pivot portion 11. A first elastic slot 14 is located near the first locking teeth 13 on each first pivot portion 11, between the recessed hole 12 and the first locking teeth 13. A tapering slope 15 is provided on the inner surface of each first pivot portion 11 where the first locking teeth 13 extend towards the recessed hole 12.
[0035] The two temples 2 are the two first pivot parts 11 that are movably pivotally connected to both sides of the frame 1. Each temple 2 has two opposing second pivot parts 21 at one end, with a corresponding upper and lower insert 22 on each second pivot part 21. These inserts 22 are correspondingly embedded in the two recessed holes 12 of the frame 1 for positioning and fixation. Furthermore, each second pivot part 21 has a plurality of protruding second teeth 23 at the position corresponding to the first retaining teeth 13. These second teeth 23 engage with the first retaining teeth 13 and can pivot elastically relative to each other, thereby causing the two temples 2 to pivot arbitrarily open or close and be positioned relative to the frame 1. A second elastic slot 24 is provided on one end of each temple 2 adjacent to the second retaining teeth 23.
[0036] During assembly, such as Figure 1 , Figure 2 and Figure 3As shown, the two second pivot portions 21 of the temple 2 are brought closer to the two first pivot portions 11 of the frame 1. This allows the corresponding upper and lower inserts 22 of the two second pivot portions 21 to move towards the insertion hole 12 via the opposite inner surfaces of the two first pivot portions 11 and the inclined surfaces 15 of the first retaining teeth 13. When the two inserts 22 move up and down along the tapering inclined surfaces 15 respectively [as...] Figure 4 As shown, because the two inserts 22 are limited and pressed by the two inclined surfaces 15, the two inserts 22 will elastically approach each other until they pass through the two inclined surfaces 15 and reach the position of the two insertion holes 12. At this point, the two inserts 22 are no longer limited and pressed by the two inclined surfaces 15, and the two inserts 22 are stretched apart by their elasticity, so that the upper and lower inserts 22 are respectively inserted into the two insertion holes 12 and fixed in place. Figure 5 [As shown]. Simultaneously, the second locking teeth 23 protruding from the two second pivot portions 21 can correspondingly engage with the first locking teeth 13 on the periphery of the two first pivot portions 11 [as shown]. Figure 6 As shown in the image.
[0037] When it is necessary to adjust the opening or closing of the temple 2 relative to the frame 1, such as Figure 6 As shown, the temple 2 pivots relative to the frame 1 around the two inserts 22. This allows the second locking teeth 23 of the two second pivot joints 21 to rotate relative to the first locking teeth 13. When the second locking teeth 23 and the first locking teeth 13 pivot relative to each other and their tips intersect [as shown in the image]... Figure 7 [As shown], when the second locking teeth 23 are subjected to a reaction force from the first locking teeth 13, they elastically compress the second elastic slot 24, causing it to deform slightly, allowing the second locking teeth 23 to elastically retract. Simultaneously, when the first locking teeth 13 are subjected to a reaction force from the second locking teeth 23, they elastically compress the first elastic slot 14, causing it to deform slightly, allowing the first locking teeth 13 to elastically retract. This allows the second locking teeth 23 to smoothly pass through the first locking teeth 13 for engagement and pivoting [e.g.]. Figure 8 As shown, this allows the two second pivot parts 21 to pivot relative to the two first pivot parts 11 without being obstructed, and to smoothly and elastically pivot and transmit power, so as to drive the two temples 2 to pivot and unfold or fold and position arbitrarily relative to the frame 1.
[0038] Thus, by means of the second locking teeth 23 of the temple 2 engaging with the first locking teeth 13 of the frame 1, the temple 2 can be reliably pivoted relative to the frame 1, thereby allowing the two temples 2 to pivot and unfold or retract and be positioned relative to the frame 1 at will. Furthermore, when the second locking teeth 23 and the first locking teeth 13 pivot relative to each other and their tips intersect, the second elastic slot 24 and the first elastic slot 14 can be retracted and compressed respectively, facilitating the smooth relative pivoting of the second locking teeth 23 and the first locking teeth 13 without obstruction or wear, thus extending their service life.
[0039] The two first pivot portions 11 have tapered inclined surfaces 15 on their opposite inner sides. When the two inserts 22 pass through these inclined surfaces 15, they can be elastically compressed relative to each other until they are disengaged. Then, they elastically expand, allowing the inserts 22 to be elastically engaged within the mounting holes 12, thus facilitating assembly and preventing detachment. Furthermore, the inserts 22 of the temple 2 can elastically engage within the mounting holes 12 of the frame 1, ensuring a tight fit and preventing loosening. This overcomes the durability issues of conventional metal screws, and makes assembly and disassembly quite easy.
[0040] Based on the above description of the embodiments, it should be fully understood that the operation, use and effects of this utility model are as follows. The above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of implementation of this utility model. That is, any simple equivalent changes and modifications made in accordance with the claims and description of this utility model are within the scope of this utility model.
