Description

Technical Field

[0001] This utility model relates to a combination device, which includes a protective helmet for sports activities and an eyeglasses frame including two temples for wearing.

[0002] This invention is particularly applicable to combination devices used in sports or leisure activities (such as cycling). This invention can also be applied to other sports or activities requiring protection against head injuries, including skateboarding, horseback riding, mountain climbing, or scooter riding. Background Technology

[0003] Helmets for this purpose typically include an outer shell configured to at least partially accommodate the wearer's head, the shell being made of a rigid material, particularly a thermoplastic polymer, reinforced with fibers when necessary.

[0004] It is known that such helmets, especially cycling helmets, typically include multiple ventilation sections arranged on the helmet to allow ventilation for the wearer's head.

[0005] To protect the wearer's eyes during activities, especially from sunlight, wind and / or dust, the wearer may also wear eyeglasses with two temples for wearing, each temple resting on one of the wearer's ears.

[0006] During the wearer's activities, the wearer may need to remove the glasses, for example, depending on changes in light and / or weather conditions, and may need to store the glasses.

[0007] Therefore, known protective helmets are designed for use with specific eyeglasses to form a combination device that is particularly commercially viable. In such combinations, the helmet includes at least a pair of side vents, the positions of which are designed to allow one temple of each eyeglass to slide into a storage position on the helmet.

[0008] This arrangement allows the wearer to easily store their glasses when they don't want to wear them, while also making them readily available when they do want to wear them, without having to rummage through backpacks or extra storage compartments.

[0009] To keep the eyeglasses in a stored position on the helmet, the eyeglasses and / or helmet are arranged such that, in the stored position, each temple of the eyeglasses applies a radial clamping force on the edge of the corresponding ventilation section.

[0010] Specifically, document EP-4154747 describes a combined device in which each ventilation section carries a holding device for eyeglasses. Each holding device includes a resilient retainer and a guide. The resilient retainer is at least partially positioned within the ventilation section to retain the temple by friction, and the guide is used to guide the temple to align with the resilient retainer.

[0011] This arrangement is not entirely satisfactory because it requires additional parts to be added to the helmet, thus increasing the complexity of implementation. Furthermore, the elastic retainer wears down with use, which, over time, compromises the retention of the eyeglasses in their stored position on the helmet. Utility Model Content

[0012] The present invention aims to improve upon the prior art by providing a combined device in which eyeglass components can be held in a stored position on a protective helmet in a simple and reliable manner.

[0013] Therefore, this utility model proposes a combined device including a protective helmet and eyeglasses. The protective helmet is used for sports activities, and the eyeglasses include two temples for wearing. The protective helmet includes a shell configured to at least partially accommodate the wearer's head. The protective helmet has at least one pair of side vents positioned to allow the temples to slide into a storage position on the protective helmet, in which a temple segment of each temple applies a radial clamping force on the edge of the corresponding side vent. The combined device is characterized in that each temple segment has a retaining portion for holding the temple in the storage position, the retaining portion dividing the corresponding temple segment into an upstream portion and a downstream portion, configured such that the radial separation distance of the upstream portions is less than the radial separation distance of the downstream portions.

[0020] The following description of the assembly, taken in conjunction with the accompanying drawings, includes a protective helmet 1 for sports activities and eyeglasses 2.

[0021] The helmet 1 shown is particularly suitable for sports or recreational activities such as cycling. Helmet 1 can also be used for other sports or activities that require protection against head injuries, including skateboarding, horseback riding, mountain climbing, or scooter riding.

[0022] The helmet 1 includes a shell 4 configured to at least partially accommodate the wearer's head, particularly at least the upper part of the head.

[0023] In this specification, spatial positioning terms (front, back, outside, inside, left, right, etc.) are used with reference to the relative position of the helmet 1 or eyeglasses 2 relative to the wearer's head when the wearer is wearing the helmet and / or eyeglasses. Specifically, the term "longitudinal" refers to the direction parallel to the sagittal midline planes P and P' of the helmet 1 or eyeglasses 2. Figure 2 and Figure 2a The vertical direction is indicated by the term "radial," which refers to the direction perpendicular to the midline of the sagittal plane (also in...). Figure 2 and Figure 2a (The middle is the horizontal direction).

[0024] The outer shell 4 is made of a rigid material that has good impact resistance while being lightweight enough to ensure the wearer's comfort. For this purpose, the outer shell 4 can be made by injection molding of thermoplastic polymer materials, especially acrylonitrile butadiene styrene (ABS) and polycarbonate (PC), reinforced with fibers when necessary.

[0025] The helmet 1 also includes an inner liner 5, which is disposed within the outer shell 4 to accommodate the wearer's head. As shown, the inner liner 5 has a lower edge 5a that contacts the wearer's forehead and temples, especially above the wearer's eyebrows and ears, when the wearer wears the helmet 1.

[0026] Specifically, the outer shell 4 forms a shell having an inner wall, and the inner liner 5 abuts against the connected inner wall, for example by bonding or overmolding, and the inner liner may be made based on expanded polystyrene (EPS).

[0027] The inner liner 5 may at least partially cover the inner padding—especially elastic foam material—and the inner liner may be wrapped in a fabric layer to ensure the wearer's comfort when wearing the helmet 1.

[0028] To improve the helmet's retention on the wearer's head, the helmet 1 may also be equipped with an internal retainer, particularly made of plastic, which is positioned behind the wearer's neck and has a reversible tightening mechanism near the neck, for example, in the form of a rotary knob.

[0029] As a replacement or combination of these rear tightening mechanisms, the helmet 1 may also be equipped with two side straps, which are connected to the outer shell 4 and / or inner liner 5 at their upper parts and have complementary mechanisms at their lower parts to allow them to be connected in reverse under the wearer's chin.

[0030] The eyeglasses 2 includes two temples 3 for wearing, each of which rests on one of the wearer's ears when the wearer wears the eyeglasses.

[0031] In the illustrated embodiment, the eyeglasses 2 includes a frame 6, which is fitted with at least one optical lens 7, and temples 3 are mounted on respective sides of the frame.

[0032] Specifically, the eyeglasses 2 shown is an optical protective shield, sized to allow the eyeglasses to cover the upper half of the wearer's face. To this end, the eyeglasses 2 includes a lower edge with a groove 8 for resting against the wearer's nose bridge when wearing the eyeglasses. This groove is equipped with a flexible structure 9 to improve wearer comfort.

[0033] In a variant not shown, the eyeglass component 2 may also take the form of eyeglasses, with its frame 6 comprising two parts, particularly in the form of a hoop, the two parts being connected by a nose bridge, each carrying an independent optical lens.

[0034] The optical lens 7 includes a wall made of transparent material through which the wearer sees objects when wearing the eyeglasses 2.

[0035] Therefore, the wall 7 can be made of a transparent thermoplastic polymer material to reduce the risk of breakage in the event of an impact to the helmet 1 and / or the eyeglasses 2.

[0036] Preferably, the wall 7 may have optical properties to adapt to ambient brightness in order to protect the wearer's eyes from the harmful effects of solar radiation, and in particular to reduce the risk of glare for the wearer during their activities.

[0037] Furthermore, in the illustrated embodiment, both the frame 6 and the optical lens 7 are curved so that when the wearer wears the eyeglasses 2, they can be as close to the eyes as possible, thereby reducing the risk of air and / or dust passing between the frame and the eyes, and also improving the wearer's vision through the optical lens 7.

[0038] Combination Figure 1 and Figure 2 Each temple 3 is equipped with a hinge 10 for mounting the temple on the frame 6 between an unfolded wearing configuration and a folded configuration. In the unfolded wearing configuration, the temple extends rearward in a generally longitudinal direction to the rear of the frame 6. In the folded configuration, the temple folds rearward in a generally radial direction to the rear of the frame. This folding configuration allows for a reduction in the volume of the eyeglasses 2 when not in use, for example, allowing it to be stored in a pocket or in a case designed for this purpose.

[0039] Helmet 1 is also provided with at least two side vents 11, the positioning of the at least two side vents being changed to allow the temples 3 to slide into place respectively, so as to place the eyeglasses 2 in a storage position on helmet 1, in which a temple section 3a of each temple 3 applies a radial clamping force on the edge 12 of the corresponding side vent 11.

[0040] This arrangement allows the wearer to conveniently store the glasses when they do not want to use them, while also making them easy to access by following a particularly intuitive gesture when they want to wear them.

[0041] When the eyeglasses 2 is equipped with foldable temples 3, its storage position on the helmet 1 is achieved with the temples in an unfolded configuration. In this way, the wearer can save time when storing the eyeglasses 2 on the helmet 1 or removing the eyeglasses 2 from the helmet for use, without having to perform the additional operation of folding or unfolding the temples 3.

[0042] like Figure 1 , Figure 3 , Figure 4 As shown, the helmet 1 is provided with a pair of side ventilation sections 11, which are respectively arranged on the upper left and upper right sides of the helmet so as to receive the temples 3 of the eyeglasses in the storage position at the front of the helmet. This provides the wearer with an easy-to-access and intuitive position to store the eyeglasses.

[0043] Specifically, the eyeglasses 2 in the storage position are flipped horizontally and vertically relative to their wearing position, especially so that the groove 8 resting on the wearer's nose faces upward.

[0044] Preferably, the helmet 1 also includes other ventilation sections 14a-14d, which are arranged on the helmet to allow ventilation of the wearer's head. Figure 1 , Figure 3 and Figure 4 Helmet 1 also includes:

[0045] -Front upper part:

[0046] - Two lower ventilation sections 14a are formed near the lower edge 5a, arranged radially and symmetrically distributed on both sides of the sagittal midline section P of the helmet;

[0047] - Three upper ventilation sections 14b are radially aligned and symmetrical with respect to the same sagittal midline section P;

[0048] -Top: A central ventilation section 14c, extending roughly toward the top of the wearer's head, aligned longitudinally with the front central upper ventilation section 14b;

[0049] - Rear section: Two ventilation sections 14d are arranged radially and symmetrically distributed on both sides of the sagittal midline section P.

[0050] Combination Figure 1 and Figure 2b It is known that the outer shell 4 has openings 15, the side ventilation section 11 is connected to these openings, and the temple section 3a directly applies radial clamping force to the corresponding openings 15.

[0051] In this way, the eyeglasses can be stored in the helmet 1 without the need for additional parts on the helmet, which simplifies manufacturing while ensuring the reliable storage of the eyeglasses on the helmet.

[0052] As shown in the figure, the outer casing 2 has partial recesses 16, and openings 15 are formed within these recesses. Specifically, as... Figure 2b As shown, the edge 12 of the opening 15 is provided with a sharp edge 17, and the corresponding temple section 3a is subjected to a radial clamping force on the sharp edge.

[0053] Combination Figure 2 Each temple section 3a is provided with a retaining part 18 for holding the temple in a storage position. The retaining part divides the corresponding temple section 3a into an upstream part 3b and a downstream part 3c. The temple is configured such that when the temple is in the unfolded configuration, the radial separation distance D1 of the upstream part 3b is less than the radial separation distance D2 of the downstream part 3c.

[0054] In the instruction manual, the terms "upstream" and "downstream" are obtained with reference to the direction of movement of the temple 3 when it is inserted into the corresponding retaining ventilation section 11.

[0055] Therefore, each temple 3 extends from the upstream portion 3b in the opposite direction to the retaining portion 18 until the free end 19 of the temple, which is used to first insert the ventilation portion 11 during the process of placing the eyeglasses 2 in the storage position on the helmet 1. The radial distance D1 is arranged relative to the spacing with the ventilation portion 11 so that the temple is placed under radial stress on the helmet during the insertion phase.

[0056] Specifically, the extension of the upstream portion 3b is arranged to be placed on one ear of each wearer wearing the eyeglasses 2, and to improve the wearer's comfort, the extension may be provided with an elastomer cover.

[0057] Preferably, each temple 3 is arc-shaped from its free end 19 to its upstream portion 3b, so that when the wearer wears the eyeglasses 2, the temple can fit against the part of the head located behind the wearer's ear.

[0058] Subsequently, each temple 3 extends from the downstream portion 3c in the opposite direction to the retaining portion 18 until it reaches the frame 6, and is connected to one side of the frame at the downstream end, in particular by means of the folding hinge 10 of the corresponding temple 3 as described above.

[0059] In particular, the radial distance D2 is greater than the radial distance D1, and the partial release of the radial stress of the temple 3 allows the retaining part 18 to be embedded in the opening 15 when the temple 3 slides to the end in the side ventilation part 11, thereby making the retention reliable.

[0060] Preferably, and as Figure 2 , Figure 2a and Figure 2b As shown, each of the retaining parts 18 is arc-shaped and is connected to the downstream part 3c through the radial shoulder 20. When the upstream part 3b slides to the end in the corresponding ventilation part 11, the radial shoulder will abut against the sharp edge 17 to prevent the temple 3 from moving out of the storage position.

[0061] Specifically, each temple 3 is made of a material that is arranged to allow the temple to undergo slight elastic deformation as it slides into the corresponding ventilation portion 11, especially as... Figure 2 and Figure 2a The outward radial spacing indicated by the middle arrow F, the shoulder 20 abuts against the sharp edge 17 by the elastic reset of the temple at the end of the slide.

[0062] This prevents the downstream part 3c from accidentally sliding out of the ventilation section 11, thereby preventing the eyeglasses 2 from falling off in the storage position, especially under the influence of gravity, such as when the wearer lowers their head forward.

[0063] In order to remove the eyeglasses 2 when you want to remove the eyeglasses from the helmet, the wearer can grasp the eyeglasses and apply a radially outward pulling force to disengage the radial shoulder 20 from the sharp edge 17, thereby allowing the temple 3 to be removed from its vent 11 by applying a longitudinally forward pulling force.

[0064] Helmet 1 and eyeglasses 2 can be sold together or separately, which allows consumers to choose helmet 1 based on its technical and / or appearance (color, pattern, material, etc.) characteristics, while simultaneously choosing one or more eyeglasses 2 based on equipment type (shield, glasses, etc.), optical performance (sun protection level, etc.) and / or appearance (color, pattern, shape, etc.) preferences.

[0065] This arrangement also makes it easier for consumers to replace damaged eyeglasses 2 and / or helmet 1, especially when the optical lens 7, frame 6 and / or temple 3 are damaged, or the helmet 1 and / or its accessories (internal padding, locking device near the head, etc.) are damaged. It is not necessary to replace the entire helmet 1 / eyeglasses 2 assembly; only the damaged parts need to be replaced.
