Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Fig. 4 to 12 illustrate a hinge assembly according to a first embodiment of the present application, which includes a guide body 10, a first elastic member 20, a second elastic member 30, a first connecting member 40, and a second connecting member 50. Referring to fig. 9 and 10, the guiding body 10 has a first end surface 11 and a second end surface 12 opposite to each other. The first end surface 11 includes a front end surface 111 for abutting against the pile head end surface 621 to normally open the temple 70, and an outer side surface 112 and an inner side surface 113 respectively disposed on both sides of the front end surface 111. The second end face 12 includes a rear end face 121 configured to abut against the temple end face 721 to normally open the temple 70, and an upper side face 122 and a lower side face 123 respectively disposed on both sides of the rear end face 121. The first end surface 11 is provided with a first guide groove 13 in the horizontal direction, the second end surface 12 is provided with a second guide groove 14 in the vertical direction, and the first guide groove 13 and the second guide groove 14 are arranged in the guide body 10 in an intersecting manner, so that the two guide grooves are communicated in the guide body 10.

Referring to fig. 4 and 7, the first elastic element 20 is disposed in the receiving cavity 611 of the pile head 60 of a pair of glasses. The second elastic element 30 is arranged in a housing cavity at the end of a temple of a pair of spectacles. The first connecting member 40 is connected to the first elastic member 20, is slidably extensible and retractable in the axial direction of the receiving cavity 611 of the pile head 60, and has a first connecting end 41 protruding beyond the pile head end surface 621. The second link 50 is connected to the second elastic member 30, is slidably extendable and retractable in the axial direction of the accommodating chamber of the temple end, and has a second link end 51 protruding from the end face 721 of the temple end. The first elastic member 20 and the second elastic member 30 may be springs or other elastic members.

Referring to fig. 4, 6 and 7, the first connection end 41 of the first connection member 40 enters the first guide groove 13 of the guide body 10, and the second connection end 51 of the second connection member 50 enters the second guide groove 14 of the guide body 10. The first guide slot 13 and the second guide slot 14 are communicated with each other, and the communicating portion enables the first connecting end 41 and the second connecting end 51 to be hinged in the guide body 10 and to be mutually rotating spindles, the first connecting end 41 can pivot along the first guide slot 13 of the guide body 10, and the second connecting end 51 can pivot along the second guide slot 14 of the guide body 10.

The first guide groove 13 restricts the first connecting piece 40 to swing only along the groove direction of the first guide groove 13; the second guide groove 14 restricts the second link 50 from swinging only in the groove direction of the second guide groove 14. When the first connecting piece 40 is assembled on a pair of spectacle frames, the first connecting piece 40 is configured to compress the first elastic piece 20, and when the temple 70 is in the normal open state, except the first connecting end 41 entering the first guide groove 13, other parts are accommodated in the accommodating cavity 611 of the pile head 60, and the front end surface 111 of the first end surface 11 of the guide body 10 is attached to the pile head end surface 621; under the elastic force of the first elastic member 20 disposed in the receiving cavity 611, the first connecting end 41 extending out of the pile end surface 621 pulls the second connecting end 51 hinged thereto, thereby tightening the guide body 10 so that the first end surface 11 on the side of the first guide groove 13 of the guide body 10 abuts against the pile end surface 621. Similarly, the second connecting member 50 is configured to compress the second elastic member 30, the second connecting end 51 is acted upon by the counter spring force, and the guide body 10 is pulled taut by pulling the first connecting end 41 so that the second end face 12 is tightened against the temple end face 721. The first elastic piece 20 and the first connecting piece 40 are matched with the first end face 11 to realize the swinging and elastic return of the glasses legs 70 relative to the pile head 60 in the horizontal direction, and the second elastic piece 30 and the second connecting piece 50 are matched with the second end face 12 to realize the swinging and elastic return of the glasses legs 70 relative to the pile head 60 in the vertical direction, so that the glasses legs 70 rotate relative to the pile head 60 in multiple directions.

The horizontal direction refers to the horizontal rotation of the temple 70 in the frame from the state where the temple 70 is normally opened to the state where the temple 70 is closed, or from the state where the temple 70 is normally opened to the state where the temple 70 is excessively opened to the outside. The vertical direction means a direction perpendicular or substantially perpendicular to the horizontal direction.

In the spectacle arm of US10365501, with reference to fig. 1 to 3, when the spectacle arm is rotated horizontally outwards, the first connecting element 4, together with the toe end element 6 and the first spring 8, is rotated relative to the guide body 3, because the toe end element 6 is pressed against the end face 3a of the guide body 3 by the force of the compressed first spring 8, so that during the rotation, friction occurs between the end face 6a of the toe end element 6 and the end face 3a of the guide body 3. After the temples 2 are rotated for many times, the appearance plating layer on the end surfaces 3a of the guide bodies 3 is worn, which affects the quality of the product.

In the embodiment of the present application, referring to fig. 8 to 10, the first end surface 11 includes a front end surface 111 for abutting against the pile head end surface 621 to make the temple 70 normally open, and an outer side surface 112 and an inner side surface 113 respectively disposed on two sides of the front end surface 111. The front end surface 111 and the outer side surface 112 of the first end surface 11 are provided with a high convex surface and a low surface, wherein the high convex surface includes a front high convex surface 111a provided on the front end surface 111, an outer high convex surface 112a provided on the outer side surface 112, and the low surface includes a front low surface 111b provided on the front end surface 111, and an outer low surface 112b provided on the outer side surface 112. Wherein, on the front end surface 111, the front high convex surface 111a is higher than the front low surface 111b so that the front high convex surface 111a abuts against the end surface 621 of the pile head, the front low surface 111b is provided with a coloring layer, and the height difference between the front high convex surface 111a and the front low surface 111b is larger than the thickness of the coloring layer. When the front end surface 111 of the guide body 10 abuts against the toe end surface 621, the front end high convex surface 111a contacts the toe end surface 621, and the front end low surface 111b does not contact the toe end surface 621 because its surface is lower than the front end high convex surface 111 a. Typical colored layers include a plating layer or an ip plating layer, an electrophoretic layer, and an oil color layer. Thus, when the temple 70 is rotated in various horizontal directions, including a state in which the temple 70 is closed to a state in which the temple 70 is normally opened, or a state in which the temple 70 is excessively opened to the outside to a state in which the temple 70 is normally opened, the pile tip end surface 621 can only contact and wear to the high convex surface of the front end surface of the guide body 10, and the colored layer on the low surface does not contact the pile tip end surface 621, so that the colored layer is prevented from being worn by the pile tip end surface 621, and since the front end surface 111 of the first end surface 11 is exposed to the user when the temple is normally closed, the above arrangement ensures product quality.

In the embodiment of the present application, referring to fig. 9, the front high convexity 111a extends from the connection between the front end surface 111 and the inner side surface 113, passes through the front end surface 111, and extends to at least a portion of the outer side surface 112, and forms an outer high convexity 112a on the outer side surface 112. The front end surface 111 has two front high convex surfaces 111a on both sides of the first guide groove 13, the number of the front high convex surfaces 111a and the number of the front low surfaces 111b are two, and the two front high convex surfaces 111a are located between the two front low surfaces 111b, that is, the front high convex surfaces 111a are horizontally disposed on both sides of the horizontal guide groove, and the front low surfaces 111b are disposed on both outer sides of the front high convex surfaces 111 a. In other embodiments of the present application, the front end surface 111 may also include two front end low surfaces 111b located between the two front end high surfaces 111a and extending to at least a portion of the outer side surface 112. In the present embodiment, at the front end surface and the outer side surface, a high convex surface including the front high convex surface 111a and the outer high convex surface 112a is used for contacting the pile head end surface 621 to be worn, and the other area is set as a low surface to avoid being worn, so that the product quality is more improved.

In the embodiment of the present application, referring to fig. 6, 8, 11a, 12, the hinge assembly further includes a first flange 63 provided on the toe end 621; when the temple is pivoted to the outside of the pile head in the horizontal direction with respect to the pile head, corresponding to the first connection end 41 being pivoted to the outside along the first guide groove 13, the first flange 63 abuts against the rear end portion of the outer side face 112 of the first end face 11 so that the outward pivoting angle of the first connection end 41 is less than 90 °. Namely: when the first connecting member 40 and the compressed first elastic member 20 and the toe end surface 621 rotate relative to the guide body 10 until the toe end surface 621 abuts against the outer side surface 112 of the guide body 10, and the central axis of the first connecting member 40 rotates by approximately 90 ° but less than 90 ° relative to the central axis of the first connecting member 40 at the position where the temples are normally opened, for example, between 70 ° and 85 °, the first flange 63 abuts against the rear end portion of the outer side surface 112 of the guide body 10, so that the rotation of the first connecting member 40 at a larger angle is prevented, and the toe end surface 621 can be prevented from contacting a larger area of the outer side surface 112, thereby preventing the wear of the toe end surface 621 at a larger area. At the same time, the situation as in fig. 11b is avoided, namely: when the angle of the outward pivoting of the first connecting member 40 is greater than or equal to 90 °, the first connecting member 40 and the pile head end surface 621 cannot automatically rebound to the original position and are blocked; when the front end surface 111 of the guiding body 10 is provided with a high convex surface 111a and the high convex surface 111a extends to at least a part of the outer side surface 112, if the first flange 63 is not provided on the pile head end surface, the situation as shown in fig. 11b occurs in particular: the first link 40 pivots outwardly through an angle greater than 90 deg. resulting in a rebound detent condition. Referring to fig. 9 and 11a, the first flange 63 is disposed such that the front high convex surface 111a on the front end surface 111 of the guide body 10 extends only to the front side of the outer side surface 112, and the outer high convex surface 112a of a small area is formed on the outer side surface 112, so that more areas on the outer side surface 112 are protected from surface abrasion due to the surface thereof being lower than the outer high convex surface 112a, and the product quality is improved greatly.

In the present embodiment, referring to fig. 12, the first flange 63 is in the form of a strip disposed along the outer edge of the toe end 621. Adopt and set up the scheme of first flange 63 at banker's head terminal surface, the beneficial effect still lies in: so that the width dimension of the dealer head 60 can be made relatively small.

When the second link 50 and the compressed second elastic member 30 and the temple-end face 721 are rotated with respect to the guide body 10, as before, the rotation is performed by the pivoting of the second guide groove 14 in the up-down direction of the guide body 10. Referring to fig. 14, when the temple end face 721 is rotated to abut against the upper side 122 of the guide body 10 and the central axis of the second connecting member 50 is rotated approximately 90 ° but less than 90 ° with respect to the central axis thereof at the position where the temple is normally opened, wherein the second flange 73 provided along the upper side edge of the temple end face 721 abuts against the front end of the upper side 122 of the guide body 10, further rotation at a larger angle is prevented, and the temple end face 721 is prevented from contacting the front end of the upper side 122 of the guide body 10 by a larger area, thereby preventing wear of the outer side 112 of the guide body 10 by a larger area. Meanwhile, the side arms 70 can be rebounded more easily in the vertical direction, and the situation that the side arms 70 cannot rebound to the original positions due to clamping stagnation of the second connecting piece 50 and the side arms 50 when the pivoting angle of the second connecting piece 50 is larger than or equal to 90 degrees is avoided. The function of the other second flange 73 is the same.

In the present embodiment, referring to fig. 15, the second flange 73 has a strip shape, and the two second flanges 73 are respectively provided on the upper and lower side edges of the end surface 721 of the temple.
