In particular, it relates to goggles that can switch between a ventilation state that allows external air to be introduced into the goggles and a non-ventilated / sealed state that does not allow external air to be introduced into the goggles. Background Technology

[0002] As a type of goggles designed to prevent lens fogging and allow external air to enter the goggles, Patent Document 1 describes goggles with a vent at the top of the main body. In the goggles described in Patent Document 1, a cover that covers the vent from the front is provided on the main body of the goggles, preventing foreign objects flying from the front from entering the goggles through the vent.

[0003] Prior art literature Patent documents Patent document 1: Japanese Patent Application Publication No. 10-192335. Summary of the Invention

[0004] The problem that the invention aims to solve However, in the goggles described in Patent Document 1, even though they can prevent the intrusion of relatively large foreign objects flying from the front, since there is no component to block the vent, they cannot prevent, for example, dust from entering the goggles through the vent, thus limiting the environment in which they can be used comfortably and thus limiting their application.

[0005] The present invention was made in view of the above-mentioned problems, and its object is to provide a pair of goggles that can be easily and reliably switched between a ventilation state in which external gas is introduced into the goggles and a non-ventilation state in which external gas is not introduced into the goggles, thereby expanding its uses so that it can be used comfortably in a variety of environments.

The frame (20) is elastically deformable and airtightly abuts against the peripheral portion (12) of the goggle lens (10), connecting with the goggle lens (10). The at least one vent (30) is disposed in the abutment area between the peripheral portion (12) of the goggle lens (10) and the frame (20). By partially elastically deforming the frame (20), a ventilable gap (31) is formed between the peripheral portion (12) of the goggle lens (10) and the frame (20), allowing ventilation. When the partial deformation is eliminated, ventilation is blocked. The aforementioned retaining member (40) is disposed on the aforementioned periphery (12) of the aforementioned goggle lens (10) in such a way that it can engage with the aforementioned frame (20) at the aforementioned at least one ventilation section (30) when ventilation is possible, thereby maintaining the aforementioned local elastic deformation in the aforementioned frame (20).

[0007] In the goggles disclosed in this application, the aforementioned retaining member (40) includes a protrusion (41). The aforementioned protrusion (41) is provided on the aforementioned periphery (12) of the aforementioned goggle lens (10) in such a way that it can engage with the aforementioned frame (20) at the aforementioned at least one ventilation section (30) when ventilation is possible.

[0008] In the goggles disclosed in this application, at least one ventilation section (30) is provided on the upper and lower parts of the aforementioned frame (20).

[0009] In the goggles disclosed in this application, at least one ventilation section (30) is provided on the upper part of the aforementioned frame (20). Furthermore, the goggles disclosed in this application also have a barrier section (21). The barrier section (21) is provided on the outer side of the aforementioned upper part of the aforementioned frame (20) to prevent foreign objects from entering the aforementioned at least one ventilation section (30) from the direction of the user's face.

[0010] The effects of the invention The goggles according to the present invention can be easily and reliably switched between an ventilated state that allows external gas to be introduced into the goggles and a non-ventilated state that does not allow external gas to be introduced into the goggles, thereby expanding their applications so that they can be used comfortably in a variety of environments.

[0022] Hereinafter, the protective goggles according to embodiments of the present invention will be described in detail based on the accompanying drawings. Furthermore, the embodiments described below are specific examples preferred for carrying out the present invention, and thus various technical limitations are made. However, unless specifically indicated in the following description as limiting the invention, the present invention is not limited to these embodiments.

[0023] <Implementation Method> The following is for reference Figures 1 to 4 To illustrate the protective goggles involved in the embodiments of the present invention. Figure 1 This is a frontal perspective view showing the goggles of the embodiment with the ventilation section open. Figure 2 This is a rear perspective view showing the goggles according to the embodiment with the ventilation section open. Figure 3 This is a frontal perspective view showing the goggles of the embodiment with the vent closed. Figure 4 This is a rear perspective view showing the goggles according to the embodiment, with the ventilator closed.

[0024] like Figure 1 , Figure 2 As shown, the goggles of this embodiment include a goggle lens 10, a frame 20, a retaining member 40, and at least one ventilation section 30. Furthermore, the goggles of this embodiment are worn on the user's face via a strap 50. In the following description, the front-back, left-right, and up-down directions are defined based on the user wearing the goggles.

[0025] In this embodiment, the goggle lens 10 is formed of a relatively rigid resin material and has a lens portion 11 and a peripheral portion 12 that can be connected to other components. Preferred resins for the goggle lens 10 include, for example, polycarbonate, polyamide, polyester, and cellulose resin.

[0026] In one embodiment, the lens portion 11 is a flat plate-shaped component integrally formed with a right eye lens and a left eye lens, and bends backward toward the right or left from the central portion of the portion that serves as the boundary between the right eye lens and the left eye lens.

[0027] The peripheral portion 12 is a frame-shaped portion extending rearward from the outer periphery of the lens portion 11 and is integrally formed with the lens portion 11. Regarding the peripheral portion 12, in the embodiment, the width dimension of the peripheral portion 12, which is the dimension of the extension rearward from the outer periphery of the lens portion 11, is not constant, and increases as it moves from the center of the lens portion 11 toward the right or left.

[0028] like Figure 1 , Figure 2 As shown, the frame 20 is formed of a material capable of elastic deformation and is airtightly abutting against the periphery 12 of the goggle lens 10, thus connecting with the goggle lens 10. Additionally, the frame 20 has a padding portion 20a that abuts against the user's face. In this embodiment, the frame 20 is formed of a relatively soft material. If the material of the frame 20 is resin, thermoplastic elastomers such as polyurethane, vinyl chloride, and styrene-based elastomers are preferred. Furthermore, rubber materials such as silicone rubber, synthetic rubber, and natural rubber are also preferred as materials for the frame 20. Furthermore, in order to facilitate the opening and closing operation of the ventilation section 30 described later and to stably maintain the open and closed states of the ventilation section 30, the hardness of the frame 20 material is preferably Shore A 50° to Shore A 95°, more preferably Shore A 60° to Shore A 90°.

[0029] like Figure 1 , Figure 2 As shown, at least one ventilation section 30 is disposed in the contact area between the periphery 12 of the goggle lens 10 and the frame 20. The contact area refers to the area where the periphery 12 of the goggle lens 10 overlaps and contacts the frame 20.

[0030] Moreover, such as Figure 1 , Figure 2 As shown, at least one ventilation section 30 allows ventilation by forming a ventilation gap 31 between the periphery 12 of the goggle lens 10 and the frame 20 through local elastic deformation of the frame 20. Figure 3 , Figure 4 As shown in the diagram, the local elastic deformation of frame 20 is eliminated and gap 31 is closed, preventing airflow.

[0031] Additionally, in this embodiment, at least one ventilation section 30 is provided on both the upper and lower parts of the frame 20. Figures 1 to 4 In the embodiment shown, four ventilation sections 30, two on the left and two on the right, are provided on the upper and lower parts of the frame 20. Furthermore, the upper and lower parts of the frame 20 refer to the portion above the center of the highest and lowest points in the vertical direction of the frame 20, and the portion below it.

[0032] Next, refer to Figure 5 , Figure 6 The present invention will now be described in more detail regarding the goggle lenses and frames involved in the embodiments thereof. Figure 5 This is a perspective view showing the lens of the goggles involved in the embodiment. Figure 6 This is a perspective view showing the framework involved in the implementation method.

[0033] like Figure 5 As shown in the diagram, in this embodiment, the goggle lens 10 has an abutting area at the rear end of the peripheral portion 12 that abuts against the frame 20, and a fitting portion 12a is provided in the rear end of the peripheral portion 12, excluding the vent 30. The fitting portion 12a is a curved strip-shaped part provided at the rear end of the peripheral portion 12 by adding an edge to the rear end of the peripheral portion 12. In addition, a plurality of engaging recesses 12b are formed in the fitting portion 12a to engage with the frame 20.

[0034] like Figure 6 As shown in the diagram, in this embodiment, the frame 20 has a fitting groove 20b in the area of ​​the contact region that abuts against the goggle lens 10, excluding the ventilation portion 30, which engages with the fitting portion 12a of the goggle lens 10. In the fitting groove 20b, a plurality of engaging protrusions 20c are formed that engage with a plurality of engaging recesses 12b of the goggle lens 10.

[0035] The fitting portion 12a of the goggle lens 10 engages with the fitting groove portion 20b of the frame 20, and multiple engaging recesses 12b engage with multiple engaging protrusions 20c. Thus, in the contact area excluding the vent 30, the frame 20 and the goggle lens 10 are connected, and elastic deformation is constrained. On the other hand, at the vent 30, the frame 20 is not connected to the goggle lens 10 and can elastically deform. Applying force to the frame 20 at the vent 30 allows for localized elastic deformation of the frame 20.

[0036] like Figure 6 As shown in the diagram, the frame 20 of the embodiment also includes a barrier portion 21. The barrier portion 21 protrudes from the outer side of the upper part of the frame 20, surrounding the ventilation portion 30 disposed on the upper part of the frame 20 from the direction of the user's face, to prevent foreign objects from intruding into the ventilation portion 30 from the direction of the user's face.

[0037] Next, in addition to the above Figures 1 to 6 In addition, refer to Figures 7 to 11 To explain the retaining component. Figure 7 This is a front view showing the goggles involved in the embodiment. Figure 8 yes Figure 7 The AA-line cross-sectional diagram is a closed AA-line cross-sectional diagram of the ventilation section. Figure 9 This is a perspective view showing the ventilated portion of the goggles according to the embodiment, which is cut off at the AA line. Figure 10 yes Figure 7 The AA-line cross-sectional view is the AA-line cross-sectional view of the open ventilation section. Figure 11 This is a perspective view showing the ventilated portion of the goggles according to the embodiment, cut off at the AA line.

[0038] like Figure 1 , Figure 2 As shown, the retaining member 40 is disposed on the periphery 12 of the goggle lens 10 in such a way that it can engage with the frame 20 at at least one ventilation section 30 when at least one ventilation section 30 is ventilated, thus maintaining local elastic deformation in the frame 20.

[0039] like Figure 5 As shown in the diagram, in this embodiment, the retaining member 40 includes a protrusion 41. The protrusion 41 is provided at at least one ventilation section 30 protruding from the periphery 12 of the goggle lens 10 toward the user's face.

[0040] Furthermore, the protrusion 41 is disposed on the periphery 12 of the goggle lens 10 in such a way that it can engage with the frame 20 at at least one ventilation section 30 when ventilation is possible, thereby maintaining the local elastic deformation of the frame 20. If the engagement between the protrusion 41 and the frame 20 is released, the local elastic deformation of the frame 20 is eliminated, the gap 31 is closed, and at least one ventilation section 30 cannot be ventilated.

[0041] In addition, such as Figure 5 As shown, in the area at the rear end of the peripheral portion 12 of the goggle lens 10 where a vent 30 is provided, a cover plate 42 is disposed opposite to the protrusion 41 in the vertical direction. Between the cover plate 42 and the protrusion 41, there is a space equivalent to... Figure 6 The gap in the thickness of the peripheral portion 22 of the frame 20 shown in the figure.

[0042] like Figure 7 , Figure 8 , Figure 9 As shown, when at least one ventilation section 30 is closed and cannot be ventilated, at at least one ventilation section 30, the peripheral portion 22 of the frame 20 is clamped by the protrusion 41 and the cover plate 42 to ensure the airtightness of the ventilation section 30 in the non-ventilation state.

[0043] In addition, such as Figure 10 , Figure 11 As shown, when at least one ventilation section 30 is open and ventilation is possible, at at least one ventilation section 30, the peripheral portion 22 of the frame 20 is located on the inner side of the goggle lens 10 further than the protrusion 41, and a gap 31 is formed between the goggle lens 10 and the frame 20.

[0044] The above is for reference only. Figures 1 to 11 As explained, in the goggles according to the embodiment, the frame 20 is elastically deformable and airtightly abuts against the periphery 12 of the goggle lens 10. At least one ventilation portion 30 is disposed in the abutment area between the periphery 12 of the goggle lens 10 and the frame 20. By the partial elastic deformation of the frame 20, a ventilation gap 31 is formed between the periphery 12 of the goggle lens 10 and the frame 20, allowing ventilation. When the partial deformation is eliminated, ventilation is not allowed. The retaining member 40 is disposed on the periphery 12 of the goggle lens 10 in such a way that it can engage with the frame 20 at at least one ventilation portion 30 when ventilation is allowed, thus maintaining the partial elastic deformation in the frame 20.

[0045] Therefore, by simply performing operations such as locally elastically deforming the frame 20 and then eliminating that local elastic deformation, it is possible to switch between a ventilated state (allowing external gas to enter the goggles) and a non-ventilated or sealed state (preventing external gas from entering the goggles). Furthermore, by maintaining the local elastic deformation within the frame 20, the retaining member 40 can stably maintain the ventilated state, expanding its applications and enabling comfortable use in a wide variety of environments.

[0046] More specifically, as a means of switching between ventilated and non-ventilated states, one could consider, for example, providing a vent in the goggle lens 10 and a cover for opening and closing the vent. However, if a cover for opening and closing the vent is provided, the number of parts in the goggle increases, and additional fixing components are required to secure the cover in both open and closed states, further increasing the number of parts in the goggle.

[0047] In addition, the vent cover is designed to protrude from the main body of the goggles when open, and it is also designed to prevent damage or unintentional closure during use, such as due to collisions with other parts, such as security helmets, and to ensure that the ventilation and non-ventilation states can be switched stably.

[0048] According to the embodiment, the goggles can be ventilated through the gap 31 formed by the local elastic deformation in the frame 20. When the local elastic deformation is eliminated, ventilation is not possible. Therefore, no other parts such as a cover are needed, which can reduce the number of parts. Furthermore, the ventilation part 30 and the retaining member 40 can be provided in such a way that each part does not protrude from the goggle body, which can prevent damage or failure caused by collision with other parts, and can stably switch between the ventilation state and the non-ventilation state.

[0049] In particular, such as Figure 2 , Figure 10 , Figure 11 As shown, the frame 20, which enables the ventilation section 30 to be in the ventilated state, undergoes localized elastic deformation toward the interior of the goggle lens 10. This allows the protrusion 41 forming the retaining member 40 to not protrude outwards from the goggle lens 10. During use, this prevents the locally elastically deformed frame 20 or protrusion 41 from colliding with or breaking from other components, or from unintentionally switching from the ventilated state to the non-ventilated state, thus enabling more stable switching between the ventilated and non-ventilated states. Furthermore, since the ventilation section 30, retaining member 40, and other components do not protrude outwards, the gap 31 is not blocked even when a safety helmet is worn, allowing for stable ventilation.

[0050] Additionally, as referenced Figures 1 to 11As can be explained, in the goggles according to the embodiment, the retaining member 40 includes a protrusion 41, which is formed on the periphery 12 of the goggle lens 10 in such a way that it can engage with the frame 20 at at least one ventilation section 30 when ventilation is possible at at least one ventilation section 30.

[0051] Therefore, by simply applying force to the frame 20 at the ventilation section 30 and hanging or removing the periphery 22 of the frame 20 from the protrusion 41, the ventilation state and the non-ventilation state can be switched more easily. Furthermore, since the elastically deformable frame 20 is hung on the protrusion 41 in the ventilation state, even if vibration is applied from the outside, the frame 20 can be easily maintained in the state of being hung on the protrusion 41, thus stably maintaining the ventilation state.

[0052] Additionally, as referenced Figures 1 to 11 As explained, according to the embodiment of the goggles, at least one ventilation section 30 is provided at the upper part and at least one at the lower part of the frame 20. Therefore, heated air inside the goggle lens 10 can be discharged through the upper ventilation section 30, and fresh air can be introduced into the interior of the goggle lens 10 through the lower ventilation section 30. This prevents foreign objects from entering through the ventilation section 30 and simultaneously allows for ventilation to prevent, for example, lens fogging.

[0053] Additionally, as referenced Figures 1 to 11 As explained, according to the embodiment of the goggles, at least one ventilation section 30 is provided in the upper part of the frame 20, and a barrier section 21 protrudes from the outer side of the upper part of the frame 20 to prevent foreign objects from entering the at least one ventilation section 30 from the direction of the user's face. Therefore, it is possible to prevent sweat from the forehead from entering the interior of the goggle lens 10, and to more reliably prevent the lens from becoming blurry.

[0054] The above is with reference to the attached diagram ( Figures 1-11 The embodiments of the present invention are described in the above description. However, the present invention is not limited to the above embodiments and can be implemented in various forms (e.g., below (1)-(4)) without departing from its spirit.

[0055] (1) The right eye lens and the left eye lens may be formed separately rather than integrally, or independent peripheral portions may be provided in each of the right eye lens and the left eye lens, and the goggles of the present invention may be formed by two eye cup-shaped goggles.

[0056] (2) When two eye-washing cup-shaped goggles are provided, the independent frames can be connected to the two goggles respectively. When the independent frames are connected to the two goggles respectively, it is preferable to form at least one ventilation part in each of the contact areas between the two goggles and the two frames.

[0057] (3) When two eye-washing cup-shaped goggles are provided and the independent frames are connected to the two goggles respectively, it is more preferable to form at least one ventilation section at the upper and lower parts of the two frames.

[0058] (4) The retaining component is not limited to a protrusion, as long as it can maintain the local elastic deformation in the frame. For example, a female thread can be formed on the goggle lens so that the top of the screw abuts against the periphery of the frame at the ventilation part, and the screw is screwed in from the outside of the goggle lens toward the inside, thereby forming a ventilation gap between the periphery of the goggle lens and the frame.
