Mode for Carrying Out the Invention

[0019] Using FIGS. 1 to 8, the schematic configuration of the helmet 1 according to an embodiment of the present invention will be described. The helmet 1 according to this embodiment has a hammock (not shown) and a headband, each formed of a soft synthetic resin or the like, detachably attached inside a cap body 2 formed of a hard material such as synthetic resin.

[0020] As shown in FIGS. 1 to 3, the helmet 1 according to this embodiment includes, in addition to the cap body 2, a holder cover 3 and a card holder 4. The holder cover 3 is a plate-shaped transparent member that is fixed to the cap body 2 with a gap provided from the surface of the cap body 2. The card holder 4 is a plate-shaped member that is inserted into an insertion portion P (see FIG. 3) formed by the gap between the cap body 2 and the holder cover 3 while holding a card CS (see FIGS. 6 to 8).

[0021] As shown in FIGS. 1 to 3, a bulging portion 2a that bulges to the left side is provided on the left side surface of the cap body 2 (the left side surface as viewed from the user of the helmet 1). This bulging portion 2a is formed to have a predetermined thickness along the outer curved shape of the cap body 2. As shown in FIG. 2, a rectangular concave portion is formed in the bulging portion 2a, and side groove portions 21·21 are formed on both inner sides of this concave portion, and a tip side groove portion 22 is formed on the lower inner side.

[0022] A holder cover 3 made of synthetic resin is fitted into the concave portion of the bulging portion 2a. The holder cover 3 is a member mainly formed of a cover main body portion 31 that is a plate-like portion, and is formed in a substantially rectangular shape in front as shown in FIG. 4(b). The holder cover 3 is made of a transparent (or translucent) material so that the card CS held by the card holder 4 can be read visually or by an access control device or the like. The cover main body portion 31 is curved so as to cover the open portion outside the concave portion formed along the outer curvature of the cap body 2. A bottom portion 31a is formed at the lower part of the inner surface (the surface on the side of the cap body 2) of the cover main body portion 31.

[0023] Side protrusion portions 32·32 that can be inserted into the side groove portions 21·21 of the concave portion are formed on the left and right side edges of the cover main body portion 31 respectively. Also, tip side protrusion portions 33·33 that can be inserted into the tip side groove portion 22 of the concave portion are formed on the lower side edge of the cover main body portion 31. Further, two drainage holes passing through the cover main body portion 31 are formed in the vicinity of the lower edge of the cover main body portion 31.

[0024] As shown in FIG. 4(b), lock release portions 34·34 having elasticity are formed on the left and right side edges of the cover main body portion 31 respectively. A lock release protrusion 34a protrudes from the inner side (the side facing each other) of each lock release portion 34. Also, locking portions 35·35 are formed above the lock release protrusions 34a·34a.

[0025] When assembling the holder cover 3 to the cap body 2, as shown by the arrows in Fig. 2, insert the holder cover 3 into the recess of the bulging portion 2a from above, and insert the side protrusions 32·32 into the side grooves 21·21 and the tip-side protrusions 33·33 into the tip-side grooves 22 respectively. In this state, by fixing the holder cover 3 to the cap body 2, an inserted portion P is formed by the outer peripheral surface of the cap body 2 and the holder cover 3 as shown in Fig. 3.

[0026] In this embodiment, ultrasonic welding on the abutting surfaces of each other is adopted as the fixing method of the holder cover 3 and the cap body 2. However, as a method of fixing the holder cover 3 to the cap body 2, it is also possible to adopt other methods such as screwing, adhesion with an adhesive, thermal welding, laser welding, etc.

[0027] The card holder 4 is a member mainly formed by a holder main body portion 41 which is a plate-like portion, and is formed in a substantially rectangular shape in front view as shown in Fig. 4(a). The holder main body portion 41 is slightly smaller than the inserted portion P, and is formed in a curved shape along the curvature of the inner surface of the recess of the bulging portion 2a.

[0028] On the upper end side of the holder main body portion 41, a closing portion 42 having a recess 48 which is a handle is provided. The closing portion 42 is configured to completely close the opening portion of the inserted portion P when the card holder 4 is attached to the cap body 2 (see Fig. 1).

[0029] On the lower end side which is the insertion-side tip of the holder main body portion 41, a spring portion 43 which is an elastic member is formed. In this embodiment, the spring portion 43 is formed in a leaf spring shape. When the card holder 4 is attached to the cap body 2, the lower end side of the holder main body portion 41 faces the bottom portion 31a of the cover main body portion 31, and the spring portion 43 can be elastically deformed to the compression side by being pressed against the bottom portion 31a (see Fig. 6).

[0030] As shown in Fig. 4(a), on the left and right sides of the holder main body 41, elastic locking members 44, 44 protrude outward to the left and right. Further, at the left and right ends of the holder main body 41, first claw portions 45 are formed at four positions so as to be able to hold the card CS. In the card holder 4 of the present embodiment, a second claw portion 46 longer than the first claw portion 45 is provided at the left end of the holder main body 41 so that even a small card CS can be stably held. As shown in Fig. 4(a), when holding the large card CL with the card holder 4, only the first claw portion 45 can be used.

[0031] In the holder main body 41, a finger insertion hole 47 penetrating the holder main body 41 in the thickness direction is opened near the upper side of the central portion in the left - right direction. The user of the helmet 1 can easily remove the card CS by inserting the fingertip from the back side of the finger insertion hole 47 and lifting the card CS so as to push it out.

[0032] When attaching the card holder 4 to the cap body 2, as shown by the arrows in Figs. 3 and 5, the card holder 4 is inserted into the insertion portion P from above. At this time, the spring portion 43 in the card holder 4 abuts against the bottom portion 31a of the holder cover 3 and elastically deforms to the compression side as shown in Fig. 6. Further, the locking members 44, 44 are elastically deformed inward by the side walls of the holder cover 3 (above the locking portions 35), and then the elastic deformation is released outward below the locking portions 35, 35. At this time, the locking members 44, 44 are arranged at the same vertical position as the unlocking protrusions 34a, 34a of the unlocking portions 34, 34.

[0033] Since the locking members 44, 44 protrude outward below the locking portions 35, 35, the upward displacement of the card holder 4 is restricted by the locking portions 35, 35. That is, the state in which the spring portion 43 is elastically deformed to the compression side as shown in Fig. 6 is maintained by the locking members 44, 44 and the locking portions 35, 35. That is, the card holder 4 is fixed by the holder cover 3 inside the insertion portion P. At this time, the card CS held by the card holder 4 is visible from the outside of the helmet 1.

[0034] When removing the card holder 4 from the insertion part P, the unlocking parts 34·34 are pressed inward as shown in Fig. 7. As a result, the unlocking protrusions 34a·34a elastically deform the locking members 44·44 inward, and the displacement restriction of the card holder 4 upward by the locking parts 35·35 is released. At this time, the elastic energy of the spring part 43 is released, and as shown in Fig. 8, the spring part 43 moves the card holder 4 upward on the side opposite to the insertion side in the insertion part P. Thereby, the user of the helmet 1 can remove the card holder 4 from the insertion part P, and the unlocking of the locking member is maintained.

[0035] As described above, in the helmet 1 according to the present embodiment, the card holder 4 can be removed from the insertion part P only by pressing the unlocking parts 34·34 without bending the holder main body part 41 or applying a large force to the card holder 4. Therefore, the card holder 4 can be removed from the cap body 2 with one hand, and the operation of removing the card CS from the card holder 4 can be simplified, reducing the work burden on the user.

[0036] Also, in the helmet 1 according to the present embodiment, since the card holder 4 can be removed from the insertion part P only by pressing the unlocking parts 34·34 without bending the holder main body part 41, the possibility of damage to the card holder 4 can be reduced. That is, since the progress of deterioration in the card holder 4 can be delayed, it is possible to suppress costs such as replacement costs. Thus, according to the helmet 1 according to the present embodiment, it is possible to remove the card holder 4 with one touch by one hand, reducing the work burden on the user when removing the card CS, and also reducing the possibility of damage to the card holder 4.

[0037] In the helmet 1 according to the present embodiment, although the spring portion 43 has a leaf spring shape, its shape is not limited as long as it can be elastically deformed on the compression side. Other shapes such as coil springs, disc springs, torsion bars, and spiral springs can be adopted. In addition, it is also possible to form the elastic member with a resin material other than a spring. However, from the viewpoint of being integrally formed with the card holder 4 by resin molding, it is preferable that the spring portion 43 has a leaf spring shape.

[0038] In addition, as the material of the card holder 4, polycarbonate, ABS, polystyrene, polyethylene, polypropylene, polylactic acid, etc. can be used. However, from the viewpoint of having fatigue characteristics that can withstand the repeated reciprocating motion in the spring portion 43, it is preferable to adopt polycarbonate.

[0039] In the helmet 1 according to the present embodiment, the spring portion 43, which is an elastic member, is formed at the insertion-side tip of the card holder 4. However, it is also possible to arrange the elastic member at other locations. For example, it is also possible to adopt a configuration in which a spring portion, which is an elastic member, is provided at the bottom 31a of the holder cover 3 facing the insertion-side tip of the card holder 4.

[0040] In the helmet 1 according to the present embodiment, the inserted portion P has an upwardly open shape, and the card holder 4 is configured to be inserted downward. However, the insertion direction of the card holder 4 is not limited, and it is also possible to adopt a configuration in which it is inserted by sliding in the horizontal direction. In this case, the spring portion, which is an elastic member, is provided at either the insertion-side end of the card holder 4 or the portion of the holder cover 3 facing the insertion-side end.

[0041] Further, in the helmet 1 according to the present embodiment, the locking members 44·44 are provided on the card holder 4, and the unlocking portions 34·34 are provided on the holder cover 3. However, the arrangement of the locking members and the unlocking portions can be other configurations. That is, the locking members can be provided on the holder cover 3 and the unlocking portions can be provided on the card holder 4.

[0042] Further, in the helmet 1 according to the present embodiment, by adopting a so-called push-type unlocking method in which the unlocking portions 34·34 are pressed to unlock the locking members 44·44, the workability and durability during unlocking are improved. However, other configurations such as a pull type or a latch type can be adopted as the unlocking method other than the push type.

[0043] Further, in the helmet 1 according to the present embodiment, the locking members 44·44 are provided at two upper positions on both the left and right sides of the card holder 4 to prevent malfunction of accidental unlocking. However, the number of locking members is not limited to the present embodiment and can be provided at one position or three or more positions.

[0044] Also, when the locking members 44·44 are provided at two or more positions, the installation positions are not limited. However, from the viewpoints of preventing malfunction and ease of unlocking, it is preferable to provide them at two upper positions on both the left and right sides as in the present embodiment. Further, from the viewpoint of ease of unlocking, the locking members 44·44 are preferably provided on the side opposite to the insertion side of the card holder 4 (the upper end portion in the present embodiment).

[0045] Further, in the present embodiment, a closing portion 42 is provided on the upper end side of the holder main body portion 41, and the closing portion 42 is configured to close the opening portion of the insertion portion P when the card holder 4 is attached to the cap body 2. Thereby, it is possible to prevent dust, dust, rainwater, etc. from entering the inside of the insertion portion P. Note that the closing portion can also be configured to be separated from the card holder 4.

[0046] In addition, in the present embodiment, the inserted portion P is formed by the outer peripheral surface of the cap body 2 and the holder cover 3, and the card holder 4 is inserted into the inserted portion P. However, the helmet card holding mechanism including the inserted portion P may be configured as a single unit, and the helmet card holding mechanism may be detachably attached to the cap body 2.

[0047] Specifically, a holder cover formed of a transparent member that can be attached to the cap body 2 of the helmet and having the inserted portion P, and a card holder inserted in a state of holding a card in the inserted portion P constitute a helmet card holding mechanism. Then, an elastic member that can be elastically deformed to the compression side by being pressed by the other is provided on either the insertion-side tip of the card holder or the bottom of the inserted portion P that faces the insertion-side tip.

[0048] Furthermore, at least one of the card holder and the holder cover is provided with a locking member that maintains the state in which the card holder is inserted into the inserted portion and the elastic member is elastically deformed. Then, by releasing the locking member in a state where the card holder is inserted into the inserted portion P, the elastic energy of the elastic member is released, and the elastic member moves the card holder to the side opposite to the insertion side in the inserted portion P, thereby maintaining the release of the locking member.

[0049] In the helmet card holding mechanism configured as described above, the card holder can be removed from the inserted portion P simply by releasing the locking member without bending the card holder or applying a large force to the card holder. Therefore, the card holder can be removed from the cap body 2 with one hand, the operation of removing the card from the card holder is simplified, and the work burden on the user can be reduced.
