Description

Swimming goggles and head band structure

Technical Field

The present invention relates to swimming goggles and a headband structure, and more particularly to swimming goggles and a headband structure that a user can comfortably wear.

Background

When swimming, the user often wears swimming goggles (or goggles) to protect his eyes. Before wearing the swimming goggles, a user can adjust the head band of the swimming goggles to a longer length so that the head band can easily surround the head; the user then tightens the headband (i.e., reducing the length of the headband around the portion of the head) to secure and seal the goggles around the eyes. In order to avoid water infiltration into the goggles, the goggles are required to be moderately compressed around the eyes, but should not be excessively compressed, which may cause health damages such as discomfort of skin around the eyes and increase of intraocular pressure.

Therefore, the user usually performs several adjustments of the headband length, and starts swimming after confirming that the swimming goggles are not pressed around the eyes excessively. Sometimes, the user does not find the headband to be too tight or too loose until swimming, and then adjusts the headband length again. It is not very convenient for the user to adjust the length of the headband to provide the headband with the proper tightness (tension).

In addition to swimming goggles, goggles used in other sports or occasions, etc., the user may also have the inconvenience of adjusting the length (tightness) of the headband when wearing them.

The technical features in the above summary of the invention may also be used as technical content of the embodiments, or may be used as possible variations of the embodiments. The orientations (such as front-back, left-right, two-sided, vertical, horizontal, etc.) are relative and can be defined according to the usage status of the present invention, and are not limited to the present invention.

Referring to fig. 1A to 1C, in the preferred embodiment of the present invention, a pair of swimming goggles 1 and a headband structure 20 are provided, the swimming goggles 1 include a swimming goggle body 10 and the headband structure 20.

The swimming goggles body 10 basically includes a lens assembly 11 and a plurality of side connecting members 12, the lens assembly 11 covers and protects the eyes and the surroundings when the user wears the swimming goggles 1, and the lens assembly 11 has different configurations according to the type of the swimming goggles 1, in this embodiment, the swimming goggles 1 are used for general swimming, so the swimming goggles assembly 11 may include two lenses 111, two frames 112, a nose bridge 113, two contact pads 114, and the like. Lens 111 may be a glass or plastic lens, frame 112 covers and surrounds the periphery of lens 111, nose bridge 113 is disposed between two frames 112 and connects two frames 112 (nose bridge 113 and frame 112 may be integrally formed, one being molded); in other embodiments, the lenses 111 and the frame 112 can be integrally formed. A contact pad (or skirt) 114 is disposed on the frame 112 and extends rearward from the frame 112; the contact pad 114 is flexible or soft, and can conform to the face of the user (the swimming goggles wearer) to deform so as to fit the face and prevent the infiltration of moisture; in other embodiments, the two lenses 111 can be connected lenses, and the two contact pads 114 can also be connected contact pads.

The lens assembly 11 may be a portion of any swimming goggles with the u-turn belt structure removed, and the lens assembly 11 will be described in detail and with the modifications of the embodiment and the details thereof being known to those skilled in the art.

The side connecting members 12 are respectively disposed on two sides (left and right sides) of the lens assembly 11, i.e., on the outer side (inner side not connected to the nose bridge 113) of one of the frame frames 112. The side connecting members 12 are used to connect the belt bodies 21 of the belt structures 20, so that the belt bodies 21 can pass through the side connecting members and the belt bodies 21 can not fall off. The side connecting member 12 is typically a ring or the like having a through-hole, and the side connecting member 12 may be integrally formed with the frame 112. In other embodiments, the side connecting members 12 and the lens assemblies 11 are manufactured separately, and then the side connecting members 12 can be assembled to the frames 112 of the lens assemblies 11.

Referring to fig. 2A and 2B, in the present embodiment, the side connecting member 12 includes a protrusion 121 and two barbs 122, the protrusion 121 is disposed on the frame 112 and transversely extends from the frame 112, and the barbs 122 are disposed on the protrusion 121 and extend toward the frame 112 without contacting the frame 112. The bump 121 and the two barbs 122 form a T-shaped structure. The belt body 21 can pass through the space between the protrusion 121 and one barb 122, then bend, and pass through the space between the protrusion 121 and the other barb 122; specifically, the belt 21 is hung on the bump 121 and then is restrained by the two hooks 122 without falling off. Since the barbs 122 are soft or flexible, the user can pull the barbs 122 to hang the belt 21 on the protrusions 121 conveniently.

Referring to fig. 1A to 1D again, the headband structure 20 of the swimming goggles 1 will be described. The headband structure 20 includes the above-mentioned band 21, an adjusting member 22, a positioning member 23 and a fixing member 24. The belt body 21 has elasticity, and can be stretched by a user to store elastic potential energy. Belt body 21 is preferably a bungee strap that is substantially stretchable and non-flat, facilitates sliding of adjustment member 22, and the like. In other embodiments, the belt body may be made of silicone rubber (silicone rubber), thermoplastic rubber (thermoplastic rubber) or polyvinyl chloride (polyvinyl chloride), and the belt body 21 may also be a braided rope (braided strap).

The belt 21 can pass through and be hooked on the two side connecting members 12 of the lens assembly 11, and then the two end portions of the belt 21 can be arranged side by side (can be further fixed by the fixing member 24) to form a first surrounding portion 211, a second surrounding portion 212, and an overhanging portion 213, which are integrally formed and extended, and these portions are located behind the lens 111. The first and second surrounding

portions

211 and 212 are substantially half-circles, surround at least from both sides to the rear side of the head of the user, and contact the head of the user when tightened, and the hanging portion 213 does not contact the head of the user but hangs behind the head. The length changes of the first surrounding portion 211, the second surrounding portion 212, and the hanging portion 213 are opposite to each other, and when the first surrounding portion 211 and the second surrounding portion 212 are shortened, the hanging portion 213 is lengthened.

Next, the adjusting member 22, the positioning member 23, and the fixing member 24 of the headband structure 20 will be described. The adjusting member 22 is located in front of the positioning member 23 and the positioning member 23 is located in front of the fixing member 24 with respect to the lens assembly 11 (or the head of the user). In other words, the adjusting member 22 is located between the swimming goggle body 10 (the head of the user) and the positioning member 23, and the positioning member 23 is located between the adjusting member 22 and the fixing member 24.

The adjusting member 22 and the positioning member 23 are slidably disposed on the belt body 21, and the fixing member 24 is fixedly disposed on the belt body 21. In addition, the adjusting member 22 and the positioning member 23 also sandwich the belt body 21 to increase the static friction between the adjusting member 22 and the belt body 21 and the static friction between the positioning member 23 and the belt body 21.

More specifically, the adjusting member 22 applies a first clamping force to the belt body 21, the positioning member 23 applies a second clamping force to the belt body 22, and the static friction between the adjusting member 22, the positioning member 23 and the belt body 21 can be obtained by multiplying the static friction coefficient by the first clamping force and the second clamping force. When one of the adjusting member 22 (fixing member 23) and the belt body 21 is subjected to a force exceeding the static friction force, the two members will slide relative to each other. Fixing member 24 need not slide relative to band body 21.

Further, the adjustment member 22, the positioning member 23, and the fixing member 24 are provided on the suspended portion 213. The relative sliding of the adjusting member 22 and the belt body 21 can adjust the relative lengths of the first surrounding portion 211, the second surrounding portion 212 and the hanging portion 213. When the user wears the swimming goggles 1, the adjustment member 22 may be slid forward to abut against the head of the user by applying a force so that the first and second surrounding

portions

211 and 212 gradually tighten the head of the user. After the first surrounding portion 211 and the second surrounding portion 212 are tightened, a proper pulling force (or tightening force) is generated, so that the lens assembly 11 will not press the face of the user excessively and water will not infiltrate; the proper tension is preferably 0.6 to 1.1kg, and more preferably 0.8 kg.

Referring to fig. 3, the first clamping force F1 applied by the adjusting member 22 is set according to the pulling force to be maintained after the strap 21 (the first surrounding portion 211 and the second surrounding portion 212) is tightened on the head of the user. Assuming that the proper tension after tightening is 0.6-1.1 kg, the static friction between the adjusting member 22 and the belt body 21 is 0.6-1.1 kg accordingly. When the user applies force to make the tightening force exceed the proper pulling force, the static friction force between the adjusting member 22 and the strap 21 cannot bear the tightening force; then, the adjusting member 22 and the strap 21 automatically slide relatively to each other, so that the strap 21 is slightly loosened (as shown by the dotted line), and the tightening force of the strap 21 is reduced to a set proper tension.

Thus, the user can wear the swimming goggles 1 without worrying about the loss due to the excessive tightening force of the belt body 21. In addition, when wearing the swimming goggles 1, the user can apply a force to make the belt body 21 have a larger tightening force, and then stop applying the force to make the adjusting member 22 and the belt body 21 automatically slide relatively, so as to make the belt body 21 have a proper tension. In other words, the belt 21 can be pulled with a suitable tension by reducing the length of the belt 21 once.

After the relative sliding movement of the adjuster member 22 and the belt body 21 is stopped, the user can move the positioning member 23 against or close to the adjuster member 22. In this way, the proper length of the first surrounding part 211 and the second surrounding part 212 (i.e. the proper position of the adjusting member 22 on the band body 21) can be marked by the positioning member 23, so that when a user takes in or uses the swimming goggles 1, the user does not worry about that the adjusting member 22 will slide backwards to a large extent inadvertently to make the first surrounding part 211 and the second surrounding part 212 loosen excessively (even if the tightening force of the band body 21 is lower than the set proper tension).

Preferably, the first clamping force applied to the belt body 21 by the adjusting member 22 is smaller (i.e. not larger) than the second clamping force applied to the belt body 21 by the positioning member, and more preferably, the first clamping force is smaller than the second clamping force, i.e. the positioning member 23 is more difficult to slide on the belt body 21 than the adjusting member 22. In this way, after the positioning member 23 abuts against the adjustment member 22, the adjustment member 22 is more surely prevented from sliding backward.

Referring to fig. 4A, 4B and 5, the specific structure of the adjusting member 22 and the positioning member 23 will be described. The adjusting member 22 includes a housing 221 and at least one through hole 222 (e.g., two through holes 222), and the two through holes 222 are disposed on the housing 221 and penetrate the housing 221 in a front-back manner. The through hole 222 may be an elliptical hole or a circular hole. The through hole 222 further includes a plurality of teeth 2221, and the teeth 2221 are arranged along the circumferential direction of the through hole 222. Strap 21 can be passed through aperture 222 and then pressed against teeth 2221, i.e., teeth 2221 can dig into strap 21, deforming strap 21, thereby increasing the static friction between teeth 2221 and strap 21. By increasing the amount of interference between teeth 2221 and band body 21, the first clamping force that adjustment member 22 applies to band body 21 can be increased.

The positioning member 23 includes a housing 231, a pressing member 232 and a spring 233. The pressing piece 232 is partially disposed in the housing 231 and partially protrudes out of the housing 231; the user can press the pressing member 232 to move the pressing member 232 into the housing 231. The spring 233 is disposed in the housing 231 and may be located under the pressing member 232; one end of the spring 233 may abut against the housing 231 and the other end abuts against the pressing piece 232. The housing 231 includes at least one through hole 2311 (or two through holes 2311), and the pressing member 232 also includes at least one through hole 2321 (or two through holes 2321), and the inner diameter of the through

holes

2311, 2321 may be larger than the outer diameter of the belt body 21. The tape 21 can pass through the through

holes

2311 and 2321, and then be pressed by the pressing member 232, and clamped by the pressing member 232 and the housing 231. More specifically, the spring 233 pushes the pressing member 232 outward, so that the tape body 21 in the through hole 2321 of the pressing member 232 is also pushed, but the tape body 21 in the through hole 2311 of the housing 231 is not pushed; therefore, the belt body 21 at the boundary between the housing 231 and the pressing member 232 is bent, and the hole edges of the through

holes

2311 and 2321 sink into the belt body 21, so that the positioning member 23 and the belt body 21 are difficult to slide relatively. By increasing the elastic force of the spring 233, the second clamping force of the positioning member 23 to the tape body 21 can be increased. Once pressing piece 232 is pressed without pressing band body 21, positioning member 23 and band body 21 can easily slide relatively. The

apertures

2311, 2321 may also include teeth (not shown) to increase gripping force.

The adjustment member 22 may also adopt the implementation of the positioning member 23 and vice versa. In addition to the above-described embodiments, the adjusting member 22 and the positioning member 23 may be configured to press the belt body 21.

Referring back to fig. 1D, the fixing member 24 is used to fix the two end portions of the belt 21 as mentioned above, and when the two end portions are integrally formed, bound, adhered, etc., the fixing member 24 is not required. In addition, when the both end portions of the tape body 21 are not fixed to each other, the fixing member 24 is not required to be provided.

Referring to fig. 1B, the band body 21 can be bent to form a first surrounding portion 211 and a second surrounding portion 212, and then the bending portion 214 (i.e. the connection portion of the first surrounding portion 21 and the second surrounding portion 212) can be hooked on the side connection member 12. Referring to fig. 6, in other embodiments, the two end portions of the strap 21 can also be directly fixed to the side connectors 12 (tied to the side connectors 12 or clamped by the side connectors 12, etc.), forming a single surrounding portion 212; the adjustment member 22 is moved to increase or decrease the length of the surrounding portion 212 to adjust the tightening force of the surrounding portion 212.

In summary, the headband structure provided by the present invention can automatically adjust the band to a proper tightness, so that the swimming goggles can be comfortably worn, and the inconvenience of adjusting the length of the headband is improved. The headband structure can be used in swimming goggles, as a component of swimming goggles, or in devices such as goggles that can be worn on the head, so that the devices can be worn comfortably.

The above-mentioned embodiments are only used to illustrate the implementation of the present invention and to explain the technical features of the present invention, and are not used to limit the protection scope of the present invention. Any arrangement which can be easily changed or equalized by those skilled in the art is within the scope of the present invention, and the scope of the present invention is defined by the appended claims.
