Description

Bicycle Helmet

The present invention relates to a bicycle helmet having a casing and a goggle, wherein the casing has an arched accommodating space between an outer side and an inner side thereof, and the goggle is movably received in the accommodating space and It can be moved between the open position and the lower position. The goggles include a protection portion and a holding portion having an operation member on the upper side. The housing has an operating channel on its outer side that extends radially (with respect to the arched shape of the receiving recess) to the receiving recess of the housing, wherein the operating member of the goggle is engaged in the operating channel, Thereby abutting on the outer side of the housing is such that the goggle can be displaced between the split position and the lower position of the cover.

In such a bicycle helmet, at least the protective portion of the goggles is transparent, and the goggles provide protection for the wearer's eyes of the bicycle helmet in a position under the cover, for example, preventing airflow, falling objects, dust particles or insect. In order to be also used for light resistance, the goggles can be colored or can be provided with another filter device. If the user of the bicycle helmet does not need or does not want the goggles (for example, during the transportation or storage of the bicycle helmet), the goggles can be moved to the cleaving position by the operating member, and In the open position, the protective portion of the goggles is at least partially Moved into the accommodating space of the helmet shell.

Some users desire to be able to replace the goggles, for example, to choose to use goggles with or without sun protection, or to replace damaged goggles.

The types of bicycle helmets are known, for example, in the patent No. EP 2 254 462 A1 and the patent No. EP 2 689 680 A2. The bicycle helmet described in these patents includes replaceable goggles, wherein in order to replace the goggles, first, the operating member of the goggles must be separated from the goggles so that the goggles can be completely removed from the helmet. . After inserting the same goggles or new goggles, the operating member must be fixed to the goggles again. Some users regard this as difficult because during the assembly process, the goggles are not easily visible through the operating channel to secure the fixed components of the operating member.

Accordingly, it is an object of the present invention to provide a bicycle helmet having goggles that has a simple and robust design and that simplifies replacement of the goggles.

In order to satisfy the object, a bicycle helmet having the features of claim 1 is specifically provided, wherein the housing has a guiding channel on its inner side, the guiding channel extending to the inner side and the outer side. The gap between the accommodations. The guide channel is extended to the front side edge of the housing and communicates there (ie, the front side edge of the housing).

The guiding channel extends from the inner side of the helmet shell until the receiving space (specifically, facing the receiving space or the head The arched radial shape of the helmet shell). The guiding channel is extended to the front side edge of the helmet shell (specifically, in the longitudinal direction of the bicycle helmet), in particular, the guiding channel and the operating channel of the helmet shell can be along the bicycle helmet Common longitudinal extension. However, the guiding channel can be wider than the operating channel. Preferably, at least the width of the guiding channel corresponds to the width of the retaining portion of the goggles, at least the front side edge of the guiding channel, that is, at least the area of the front side edge of the helmet shell.

Because the guiding channel communicates with the front side edge of the housing, the retaining portion of the goggles (including the operating member) can be introduced into the receiving space or into the inner guiding channel of the helmet shell. Therefore, for the replacement of the goggles, the retaining portion of the goggle can be inserted into or placed in the guiding channel (specifically, in a radial direction opposite to the arch of the helmet shell), and is disposed on the goggles. The operating member on the holding portion can be introduced into the operating channel from this position. For this purpose, preferably, the operating member moves in the direction of the outer side of the helmet shell, and at the same time provides the movement of the retaining portion of the visor toward the longitudinal direction (ie, along the accommodating gap).

A limitation can be selectively made: for the retaining portion of the goggles to be introduced into the receiving recess or for the operating member to be inserted into the operating channel, the operating member itself and/or a portion of the helmet shell is temporarily slightly elastically bent.

The goggles can also be selectively guided separately by the guiding channel, as will be explained in more detail.

A bicycle helmet, especially a bicycle helmet of the present invention, generally having a concavely arched inner side and an upper convexly curved outer side, The term "outside" and "inside" of the present invention is related to the arched surface. The description of the position and orientation of the present invention normally refers to the arrangement of the bicycle helmet on the wearer's head for its intended use. For example, the term "front side" means that the bicycle helmet is disposed on the forehead area of the user and faces one side of the user's gaze direction, and the term "back side" means that the bicycle helmet is located at the wearer's head. The rear extent with the neck thus faces away from one side of the wearer's gaze direction. The "longitudinal direction" should be understood as a direction extending between the front side and the rear side of the bicycle helmet.

The cleavage position of the visor corresponds to an "upward position", in which the holding portion of the visor is completely accommodated in the accommodating space of the housing, and the protection portion is mostly or completely accommodated in the housing The housing is accommodated in the gap. Conversely, the position under the cover of the goggles corresponds to a "downward position" in which the retaining portion is mostly or completely accommodated in the receiving space of the housing, but the protecting portion is mostly or completely The outer space of the housing is removed.

Preferably, according to the arch shape of the receiving space, the goggles can be bent to be easily accommodated in the receiving space. Preferably, the retaining portion of the goggles is extendable and extends from the protecting portion toward the longitudinal direction of the bicycle helmet. The operating member of the goggle protrudes from the upper side of the holding portion.

Preferably, at least the protective portion of the goggles is transparent such that the user of the bicycle helmet can act as a transparent protective windshield. For example, weather-induced falling objects, such as raindrops or snow particles, can isolate the eyes of the bicycle helmet user by the protective portion of the goggles, so that the sight and visibility can be minimized even in harsh climates. Degree reduction. The protective portion of the goggles may further have the properties of commercial sunglasses, such as coloring. In the protective portion, techniques such as ultraviolet absorption and/or light reflection can be particularly provided. Different goggles can be provided on the helmet depending on individual needs or the aesthetics of the user. Therefore, the purpose of the simple replacement function of the goggles contemplated by the present invention is a particular advantage for the user, for example, because the goggles can be quickly replaced without being complicated according to the weather conditions at the time.

The housing of the helmet can have a dome of shock absorbing material, such as expanded polystyrene foam (EPS). The housing has a shell of polyvinyl chloride (PVC), polyethylene terephthalate (PET), polycarbonate (PC) or acrylonitrile butadiene styrene (ABS). Vents may be provided in the outer casing and the dome, preferably in alignment with one another to ensure particularly effective ventilation of the user's head surrounded by the bicycle helmet.

Preferred embodiments of the invention are described below and in the accompanying claims.

In a preferred embodiment, the guiding channel at least partially overlaps the outer operating channel. Understandably, at least a portion of the inner guiding channel overlaps the outer operating channel such that the guiding channel is disposed at least partially aligned with the operating channel. Preferably, a through hole between the inner side and the outer side of the casing is formed on the overlapping area of the guiding channel and the operating channel. When the visor is connected to the helmet shell, in the region of the through hole, an operating member disposed on the retaining portion of the visor can be simply inserted into the operating channel from the inner side of the bicycle helmet (specifically Ground, in the position under the cover of the goggles). However, such overlap is not absolutely necessary, especially when the operating member is elastically compressible, as will be described later.

In another embodiment, the guiding channel overlaps the operating channel of the housing along its corresponding longitudinal section a distance that corresponds at least to the length of the operating member of the goggle. Thereby, the operating member can be simply inserted into the front side section of the operating channel from the inside of the bicycle helmet.

In a preferred embodiment, the guiding channel of the housing is widened relative to the front side of the rear side section, wherein the width of the guiding channel at least the width of the front side section corresponds to the width of the holding portion of the goggles. And wherein the width of the guiding channel in the rear side section is smaller than the width of the holding portion of the goggles. Preferably, the overlapping region of the guiding channel and the operating channel (when present) is located on the widened front side of the guiding channel. Therefore, the holding portion of the goggles can be introduced into the accommodating space along the widened area. The lateral boundary of the guiding channel on the rear side section can be fitted to the holding portion, thereby ensuring good guiding of the holding portion and defining displacement of the goggle in the longitudinal direction.

In another preferred embodiment, the bicycle helmet has a closure member on a region of the front side edge of the housing that is detachably fixed to the inner side of the housing to close the guiding channel. After the operating member previously described is inserted into the operating channel, and preferably after the retaining portion of the goggle has at least partially entered the receiving space of the helmet shell, the closing member can be coupled to the helmet housing The front side edge closes the front side edge of the helmet shell, thereby blocking the goggle from unintentionally disengaging from the receiving space of the helmet shell. In contrast, in order to selectively separate the goggles from the helmet shell, The process is performed in the reverse order, that is, first, the closure member is removed from the front side edge of the housing, and the operating member of the goggle is displaced inwardly, thereby removing the outer operation channel, and finally, the The goggles can be pulled to the front to completely remove the accommodating gap of the helmet gap. Since the closure for the guiding channel and the recess required for this purpose are provided on the inside of the helmet shell, the housing system is rather robust.

In a preferred embodiment, the closure member can be inserted into the guide channel of the housing by a force fit and/or a form fit. For example, the insert closure can be held in place in a sandwiched or snapped manner. Alternatively, an additional fastener can be provided between the closure and the housing (eg, at least one screw, at least one pair of hook and loop fastener assemblies or a displaceable bolt).

The closure can be formed from a flexible material. In particular, the closure can be formed from an elastic material (that is, a material that can be bounced back). This feature is a particular advantage when the closure is held in a clamping manner on the guiding channel of the housing. When a snap mechanism is provided for securing the closure, the flexible material can be reduced or at least more suitable for making the components of the closure since a relatively small external force must be applied to secure and release the closure.

In another preferred development of the present invention, the retaining portion of the goggle has an engaging member on a lower side thereof, and the engaging member is engaged in a guiding channel of the housing and in a position under the cover of the goggle The engaging member contacts the closure. Thus, the engagement member cooperates with the closure member such that the closure member defines engagement with the end of the visor and the engagement member of the visor engages against the end when it reaches the position under the cover of the visor. At this time, the goggles can be guided by the engaging member being engaged in the guiding channel, and The visor moves between the splayed position and the lower position of the cover.

Preferably, the engaging member is molded as a single member or is fixed to the holding portion of the goggle.

Regarding one of the embodiments of the closure as described below to define a variable end engagement, the position of the goggles in the lower position of the cover can be adjusted by the user so as to be particularly advantageous for the goggles. Joints.

In a preferred embodiment, the closure member can be selectively fixed to the at least one first positioning point or the second positioning point on the housing, so that the sealing member is at the first positioning point and the second positioning point The length of the different guiding channels is defined on the two positioning points. For the position of the goggles under the cover, it is thereby possible to define a position at which the at least two different ends are joined. In particular, the closure can be rotated 180° or rotated 90° (for up to four different positioning points) into the guiding channel relative to the first positioning point (for two different positioning points). Therefore, by the variable length of the guiding channel, the position of the goggles under the cover can match the eye or nose of the helmet user, so that in the position of the cover, the protection portion of the goggles is completely longitudinally Covers the eye area of the helmet user, but does not abut the nose of the helmet user. Due to the swaying motion of the bicycle helmet during travel, it is particularly desirable to avoid the protection of the protection portion on the bridge of the nose, as they may cause pain to be applied to the skin of the nose. The eye area is still completely covered as intended, so that the protection portion can effectively protect the eye of the helmet user.

Alternatively or additionally, the closure has a recess on at least one end face and is opposite the other end face of the closure (specifically, phase The recess defines a larger length of the guiding channel than one of the end faces disposed opposite the end face. For example, the recess can be formed as a rectangular recess on the end face of the closure member to engage the engagement member of the aforementioned goggles in the lower position of the goggle. Therefore, in the lower position, the engaging member and the goggles are held in a relatively suitable position by the side edges of the recess, thereby avoiding the swaying motion of the goggles, for example, the bicycle is irregular. Travel on the surface. Furthermore, the width of the recess can be slightly smaller than the width of the joint. Thereby, the engaging member that engages the recess is held in the recess by the clamping method (the position under the cover), and by the manual operation of the operating member of the visor, the engaging member that engages the recess is only under the cover The position is displaced in the direction of the open position. In addition, in the displacement of the goggle from the cleaving position to the lower position of the cover to generate the clamping state, it is necessary to appropriately engage the engaging member of the goggles without suddenly engaging the closing member, thereby slightly increasing the effect. The means of force is necessary to indicate to the user of the bicycle helmet the arrival of the position under the cover. In this regard, the use of the flexible material of the closure can facilitate the development of the above features.

In another embodiment, the closure has at least one predetermined breaking point or point to be selectively matched to provide an additional or new recess on the closure by breaking or cutting the closure a predetermined portion to increase the length of the guiding channel for the engaging member. Thereby, the bicycle helmet user can increase the length of the guiding channel in a simple manner, so that the position of the goggles under the cover is suitable for personal needs.

Alternatively or additionally, in order to adjust the length of the guiding channel, in another preferred embodiment, the closure can The housing is selectively secured to at least a first longitudinal position or a second longitudinal position such that the closure defines a different length of the guiding channel in the first longitudinal position and the second longitudinal position. Thus, the closure can be secured to at least two different longitudinal positions on the helmet shell.

Another alternative includes providing a combination of a plurality of closures to the bicycle helmet user, and for the engagement member, each of the closures defines a different location for the end engagement. For example, on each of the closure members, the recessed recesses for the joint member can have different lengths. The length of the guiding channel can be correspondingly changed by various options of the closure.

In another preferred embodiment, the housing includes a dome and an insert. The dome has a vacant area on its inner side, wherein the insert is inserted into the dome and permanently fixed to the dome. The guiding channel is formed on the insert. The receiving space is formed between the dome and the insert. Since the accommodating void is formed in a simple manner by the spacing between the insert that has been inserted into the vacant area and the dome, the use of a separate insert simplifies the manufacture of the helmet. Both the dome and the insert can be formed of a shock absorbing material, in particular, all of the same material.

In another embodiment, the operating member is resiliently compressible, for example, formed from foam or as a spring portion. Specifically, due to the feature, the overlapping of the guiding channel and the operating channel can be omitted, and the operating member can be compressed on the guide of the goggle (with the holding portion) into the receiving space. Until the operational channel is reached. Upon reaching the operating channel, the operating member expands therein and automatically engages therein. Due to the radial boundary of the receiving gap, the compression occurs approximately in the radial direction (phase For the arch of the accommodating gap). In contrast, the operating member is compressed from the outside (through the operating channel) to remove the goggles from the receiving space. In this embodiment, since the front side boundary of the operation channel defines the goggles and the end of the operation member is engaged, the goggles do not accidentally fall out of the accommodation space, and thus can be completely omitted. Closure.

Preferably, the operating member is molded as a single member or is fixed to the retaining portion of the visor, thereby avoiding unintended separation of the operating member from the retaining portion of the visor.

As shown in Figures 1a, 1b and 2, a bicycle helmet 11 includes a housing 13 and a transparent goggle 15 . An arched accommodating gap is formed between the inner side and the outer side of the bicycle helmet 11, and the visor 15 is movably received therein. In terms of structure, the accommodating space 17 shown in this embodiment is formed between the dome 19 and the insert 21, and the insert 21 is inserted into the inner vacant area of the dome 19 and is permanently fixed thereto. This insert 21 is shown in detail in Fig. 4. In Figures 1a and 1b, the goggles 15 are in the cleaved position, allowing the goggles 15 to be fully guided into the receiving recesses 17.

a guiding channel 23 is formed on the insert 21; it faces in the radial direction (with respect to the arch of the receiving recess 17 or the helmet shell 13) An arched shape extends outwardly from the inner side of the helmet shell 13 to the receiving recess 17, and it extends longitudinally to the front side edge of the housing 13 to communicate there (Fig. 1b). A plurality of venting holes 25 are provided in the housing 13 to facilitate ventilation of the coated wearer's head during use of the bicycle helmet 11.

This goggles 15 is shown in detail in Fig. 3. It includes a tongue-like retaining portion 27 and a protective portion 29 in the form of a sheet, and the protecting portion 29 is attached to the lower cover position for protecting the eyes of the wearer of the bicycle helmet 11. The operating member 31 is formed on the upper side of the holding portion 27. The engaging member 37 (dashed line as shown in FIG. 3) is formed on the lower side of the holding portion 27. The goggles 15 are curved and have a concave portion 33 on the area of the protection portion 29, so that when the goggles 15 are located under the cover, the nose bridge of the helmet user is fitted over the concave portion, such as Said later.

At least under the cover of the goggles, the protecting portion 29 is turned out of the receiving space 17, as shown in FIG. The holding portion 27 of the goggles 15 is received in the receiving space 17. An operation channel 35 for engaging the operating member 31 of the visor 15 is formed on the outer side of the bicycle helmet 11 so that the manual operation can move the visor 15 at the cleavage position and the lower cover position (Fig. 2). between. For this purpose, the operating channel 35 extends radially inwardly (with the arch of the receiving recess 17 or the arch of the helmet shell 13 ) inwardly from the outer side of the helmet shell 13 to the receiving recess 17 . On the inner side, the engaging member 37 is formed on the holding portion 27 to be engaged in the guiding channel 23 (Figs. 1a and 1b). In Figure 1a, it is detachably fixed to the inside of the casing 13 (for example, by clamping configuration) The member 39 closes the front end of the guiding channel 23, that is, the area of the front side edge of the casing 13. In Figure 1b, the closure 39 is removed. Specifically, as shown in FIG. 1b, the guide channel 23 is widened before the edge adjacent the edge of the housing 13 with respect to the rear side of the center of the helmet. The width of the front side of the guiding channel 23 corresponds at least to the width of the holding portion 27 of the goggles 15.

Specifically, in FIG. 5, the operation channel 35 can be viewed from below, partially overlapping the guiding channel 23, and the portion 49 of the overlapping region extends into the widened portion of the guiding channel 23, And the portion 49 of the overlapping region has the length of the operating member 31.

A particular advantage of the illustrated bicycle helmet 11 is that the goggles 15 can be replaced in a simple manner.

After the goggle 15 is installed, after the closure member 39 is removed from the helmet shell 13, the goggles 15 are placed in the inner side of the housing 13 with the retaining portion 27 along the guiding channel 23 The front side section is located in front of the front side, and the upper side operating member 31 is engaged into the operation channel 35 of the housing 13. Then, the goggles 15 can be introduced into the accommodating space 17 until the visor 15 is completely accommodated in the accommodating space 17. In this regard, the operating member 31 is engaged in the operating channel 35, and the engaging member 37 is engaged in the guiding channel 23. The closure member 39 is then inserted into the wider portion of the guide channel 23, as shown in Figure 1a. Therefore, the closure member 39 fixes the visor 15 in the accommodating recess 17, and at the same time defines the end joint for the engaging member 37 of the visor 15 in the forward direction (the cleavage position of the visor 15). .

The closure member 39 is detachably inserted into the guiding channel 23 in. Thus, the goggles 15 can be selectively removed again in reverse order, for example, to replace the goggles 15 with different goggles.

A partial view of Fig. 1b is shown in Fig. 5, and the protective portion 29 of the visor 15 is almost completely turned out of the accommodating space 17. Specifically, FIG. 5 presents an enlarged view of a region of the guiding channel 23 and a region of the operation channel 35, and shows the covering portion in a broken line. The perspective below corresponds to the view of the inside of the helmet equivalent to Figure 1b. As already mentioned, the inner guiding channel 23 at least partially overlaps the outer operating channel 35, i.e. the guiding channel 23 is at least partially aligned on the outer operating channel 35. As described, for the attachment of the goggles 15, the free end of the retaining portion 27 of the goggles 15 having the upper operating member 31 can be inserted into the portion 49 of the overlapping region of the widened portion of the guiding channel 23. For this purpose, the width of the guiding channel 23 in the front side section (widening) is slightly larger than the width of the holding portion 27 of the goggles 15. The width of the guiding channel 23 in the rear side section is smaller than the width of the holding portion 27, that is, the lateral boundary of the guiding channel 23 is fitted to the holding portion 27. Here, where the retaining portion 27 is not visible, it is indicated by a dashed border.

Figure 6a shows a partial cross-sectional view of the bicycle helmet 11 and the section extends vertically through the guiding channel 23 and the operating channel 35 in the longitudinal direction. As shown in FIG. 6a, the goggles 15 are located at a transitional position between the cleaving position and the lower position of the cover, the operating member 31 is engaged in the operating channel 35, and the engaging member 37 is coupled thereto. Guided in the channel 23. As shown in Fig. 6a, the portion of the bicycle helmet 11 disposed above the visor 15 includes the dome 19 and the outer casing 41 except for the previously illustrated embodiment. As shown in Figure 6a, the bicycle helmet 11 is provided The portion below the goggles 15 is comprised of the insert 21, the closure 39, and an optional inner liner 43.

Figure 6a shows an alternative embodiment. Figure 6b generally corresponds to Figure 6a, but in this alternative embodiment, the operational channel 35 does not overlap the guiding channel 23. Furthermore, in Fig. 6b, the closure member 39 for inserting the guide channel 23 is not provided. In this embodiment, preferably, the operating member 31 is elastically compressible, so that the retaining portion 27 of the goggles 15 can be introduced into the receiving recess 17 on the one hand, and on the other hand, The introduced goggles 15 are fixed in the accommodation space 17. In other words, the operating member 31 is compressed in the longitudinal section 51 of the accommodating recess 17, and the operating channel 35 and the guiding channel 23 do not overlap there, and the operating member 31 reaches the operating channel 35. The operating member 31 is automatically engaged in the operating channel 35. Due to the corresponding radial boundary of the accommodating recess 17, the compression of the operating member 31 occurs substantially in the radial direction (the arch shape with respect to the accommodating recess 17). The boundaries are formed by the dome 19 and the insert 21, as shown in Figure 6b.

Figures 7a, 7b and 7c show different embodiments of the closure 39. The closure member 39 shown in Fig. 7a has a generally rectangular recess on the end face which forms a recess 45 for the engagement member 37. In this regard, the depth of the recess defines the effective length (Fig. 1a) of the guide channel 23 into which the closure 39 is inserted. In particular, the depth of the recess also defines the position of the visor 15 such that the engaging member 37 engages the recess 45 of the closure member 39 and the visor 15 pivots out of the accommodating space as much as possible ( Cover the position). The closure 39 can select two different positioning points One of the closures 39 is fixed to the helmet shell 13 , that is, the closure member 39 faces the guide channel 23 with one of the end faces having the recesses 45 or the oppositely disposed end faces for the cover of the goggles 15 The lower position defines two different end joints.

Alternatively or additionally, the closure member 39 can be selectively inserted into the guiding channel 23 at different positions in the longitudinal direction, whereby the length of the guiding channel can likewise be varied.

With the possibility of using these changes, the protective portion 29 of the goggles 15 is precisely disposed in front of the eye area of the helmet user in the position of the cover, and the protection portion 29 does not abut the helmet wearer. The bridge of the nose.

The embodiment of the closure member 39 shown in Fig. 7b corresponds to Fig. 7a, and a predetermined breaking point 47, 47' is added to the closure member 39. For example, the predetermined breaking points 47, 47' can be implemented by perforations. The position of the recess 45 can be changed toward the center of the closure member 39 by breaking (e.g., by means of a screwdriver) the portion of the closure member 39 defined by the predetermined breaking point 47, 47'. The range of rotation of the goggles 15 can be increased by the fact that the protective portion 29 of the goggles 15 is more rotated out of the receiving recess 17 in the lower position of the cover. A viable means of applying this change is such that the protective portion 29 is accurately placed in front of the eye area of the helmet user in the position under the cover.

Figure 7c shows another embodiment of the closure member 39, i.e., a relatively concave portion of different depths is provided on the end face. The recesses define their recesses 45, 45', but only one of them serves as the joint member 37. The ends are joined. As in the embodiment shown in Figure 7c, the closure member 39 can be rotated 180° to selectively insert the guide channel 23. The closure member 39 is fixed thereto, and its recesses 45, 45' are joined as ends for the engagement member 37. Thus, the position of the protection portion 29 can be varied in a particularly simple manner and there are no additional appliances in the position under the cover of the goggles 15.
