Description

[Technical field]

[0001] The present invention relates to a helmet to which an umbrella can be attached, and a sunshade member fixing jig for fixing a sunshade member to a helmet. [Background technology]

[0002] Helmets are used in a wide range of applications, including civil engineering sites, factories, farms, and other work sites, as well as so-called DIY and outdoor leisure activities (fishing, camping, etc.). Due to their structure, helmets have poorer breathability than hats and tend to accumulate heat, which can lead to discomfort for the wearer. For this reason, helmets with a sunshade function have been proposed (see, for example, Patent Documents 1 to 3).

[0003] However, conventional helmets with sunshade functions have a problem in that the sunshade members are fixed to the helmet and can only block sunlight from a specific direction. For example, when wearing a helmet while fishing on a breakwater, the wearer is exposed to sunlight from behind when he starts fishing, but as time passes, the sun moves and he is exposed to sunlight from the side. In such a case, conventional helmets with sunshade functions have a problem in that they cannot block sunlight sufficiently. [Prior art documents] [Patent documents]

[0011] Hereinafter, the present embodiment will be described with reference to the accompanying drawings. In the accompanying drawings, functionally identical elements may be indicated by the same numbers. Note that the accompanying drawings show embodiments and implementation examples according to the principles of the present disclosure, but these are for understanding the present disclosure and are not to be used to interpret the present disclosure in a limiting manner. The description in this specification is merely a typical example and does not limit the scope or application of the present disclosure in any sense.

[0012] In the present embodiment, the description is given in sufficient detail for a person skilled in the art to implement the present disclosure, but it should be understood that other implementations and forms are possible, and that changes in configuration and structure and substitutions of various elements are possible without departing from the scope and spirit of the technical ideas of the present disclosure. Therefore, the following description should not be interpreted as being limited thereto.

[0013] [First embodiment] A helmet 1 according to a first embodiment of the present invention will be described with reference to Figures 1 to 7. First, an outline of the overall structure of this helmet 1 will be described with reference to the perspective view of Figure 1. This helmet 1 comprises a helmet main body 10 and a sunshade member fixing jig 20 that is attached to the helmet main body 10 via a hole H1 (see Figure 2) formed near the top of the helmet main body 10.

[0014] One example of the sunshade member attached to the sunshade member fixing jig 20 is a commonly available umbrella (the length of the handle is preferably cut or adjusted to a length shorter than that of a general umbrella). However, it is also possible to use other types of sunshade members that have a structure similar to that of an umbrella and can provide shade, and any sunshade member that has a handle that can be attached to the sunshade member fixing jig 20 and a sunshade member that can be attached to the handle will suffice. Since the diameter of a helmet is about 25 cm to 30 cm, the diameter of the umbrella is preferably about 30 to 50 cm, and the length of the handle is preferably about 20 to 40 cm.

[0015] The helmet 1 may be a helmet of a known structure that is generally available at a home improvement store or the like. However, a hole H1 for attaching a sunshade member fixing jig 20 is provided at the top of the helmet 1 (see FIG. 2). The sunshade member fixing jig 20 includes a rotating shaft member 21 that is attached to the surface of the helmet body 10 via the hole H1 and forms a rotating shaft, and a curved plate member 22 that is attached (a part of which is fixed) to the rotating shaft member 21 and can rotate around the rotating shaft of the rotating shaft member 21 (the center of the hole H1 in FIG. 1).

[0016] The configuration of the sunshade member fixing jig 20 will be described in detail with reference to Figures 3 to 6. The rotating shaft member 21 of the sunshade member fixing jig 20 further includes a first member 211 provided on the front side of the helmet body 10, and a second member 212 provided on the back side of the helmet body 10 and configured to be able to fit with the first member 211 through a hole portion H1. The first member 211 and the second member 212 fit with each other through the hole portion H1 of the helmet body 10, so that the rotating shaft member 21 can rotate around the rotation axis relative to the helmet body 10.

[0017] The first member 211 has a cylindrical shape with a height of about 2 to 5 cm and a diameter of about 1.5 to 4 cm, extending in the normal direction of the surface of the helmet body 10, and is provided with an insertion hole 213 formed downward from its upper end, and a fixing screw 214. The size of the first member 211, including the length, diameter, etc., can be changed according to the thickness and length of the handle of the sunshade member to be attached, the size of the umbrella, etc., and is not limited to a specific size. The insertion hole 213 is preferably formed to extend horizontally with respect to the rotation axis (the central axis of the hole H1), but is not limited to this.

[0018] The insertion hole 213 may have a depth of about 1.5 cm to 4 cm from the upper end, and for example, an umbrella handle is inserted into it. The fixing screw 214 is screwed into the side surface of the first member 211 so as to be able to reach the insertion hole 213. By screwing the fixing screw 214, the umbrella handle can be fixed to the first member 211. That is, the first member 211 constitutes a sunshade member fixing part for fixing a sunshade member such as an umbrella, similar to the sunshade member fixing part 222 described later.

[0019] The curved plate member 22 of the sunshade member fixing jig 20 is configured to include a sliding curved plate 221 and a sunshade member fixing portion 222, and is configured to be rotatable about the rotation axis of the rotating shaft member 21. The sliding curved plate 221 is fixed to the first member 211 of the rotating shaft member 21, and is configured to be rotatable together with the rotating shaft member 21 around the rotation axis.

[0020] The sliding curved plate 221 has a curved shape that approximately matches the surface shape of the helmet body 10. As an example, the sliding curved plate 221 can have a shape that includes a first curved surface portion near the rotating shaft member 21, and a second curved surface portion that is located at a position separated from the rotating shaft member 21 and has a shape obtained by bending the first curved surface portion along the circumferential direction.

[0021] The sunshade member fixing part 222 is formed so as to extend from the second curved surface part of the sliding curved plate 221 in a direction substantially perpendicular to the surface of the helmet body 10. The sunshade member fixing part 222 may have substantially the same structure as the first member 211 of the rotating shaft member 21, with an insertion hole 223 penetrating near its center and a fixing screw 224 screwed into its side surface.

[0022] The sunshade member fixing part 222 functions as a sunshade member fixing tool for attaching the sunshade member at a position separated from the rotating shaft member 21. The sunshade member fixing part 222 can be cylindrical with a height of about 2 to 5 cm and a diameter of about 1.5 to 4 cm. The insertion hole 223 can be about 1.5 to 4 cm deep from the upper end, into which a part of the sunshade member (for example, an umbrella handle) described later is inserted. The fixing screw 224 is screwed into the side surface of the sunshade member fixing part 222 so as to be able to reach the insertion hole 223.

[0023] Since the sliding curved plate 221 has the curved shape as described above, the sliding curved plate 221 always has a large contact area with the surface of the helmet body 10, even when rotating around the rotating shaft member 21, and therefore can stably hold the sunshade member without being affected by wind, etc.

[0024] The rotating shaft member 21 will be described in more detail with reference to Fig. 4 and Fig. 5. Fig. 4 shows a state in which the first member 211 and the second member 212 are engaged with each other, and Fig. 5 shows a state in which the two are separated before being engaged with each other. The second member 212 includes a base portion 2121, a hole insertion portion 2122, and a first member insertion portion 2123.

[0025] The base 2121 is a lower end of the second member 212, and has a diameter larger than that of the hole H1. The base 2121 is located on the back side (wearer side) of the helmet body 10 when the mounting of the rotating shaft member 21 to the helmet body 10 is completed. The hole insertion part 2122 has a diameter slightly smaller than that of the hole H1, and is inserted into the hole H1. The first member insertion part 2123 is inserted into a hole (not shown) provided below the first member 211. After the second member 212 is inserted and fitted into the first member 211, a groove C1 extending in the circumferential direction around the rotating shaft is formed between the hole insertion part 2122 and the first member 211, and the sliding curved plate 221 is fitted into this groove C1.

[0026] 6, the sliding curved plate 221 has a U-shaped recess V1 that fits into the above-mentioned groove C1. The curved plate member 22 is fixed to the rotating shaft member 21 by sandwiching the groove C1 with this U-shaped recess V1.

[0027] Next, the operation of the helmet 1 and the sunshade member fixing jig 20 of the first embodiment will be described with reference to FIG. 7. When the handle of an umbrella UB as a sunshade member is fixed to the sunshade member fixing part 222, the umbrella UB is fixed to the helmet 1 at an inclination with respect to the rotation axis AX (the center of the hole part H1). As shown in FIG. 7(a), when the sliding curved plate 221 is rotated so that its longitudinal direction faces the rear of the helmet 1, the umbrella UB is inclined backward with respect to the helmet 1. This allows the wearer of the helmet 1 to effectively avoid solar radiation from behind himself. The sliding curved plate 221 can be rotated, for example, by the wearer pinching the sunshade member fixing part 222 or the handle of the umbrella UB with his fingers and moving it in the circumferential direction.

[0028] On the other hand, if sunlight comes from the front of the wearer of the helmet 1 over time, as shown in Fig. 7(b), the sliding curved plate 221 can be rotated as shown by the arrow AR so that the sliding curved plate 221 faces the front of the helmet 1. This causes the umbrella UB to tilt forward relative to the helmet 1, making it possible to effectively avoid sunlight coming from the front of the helmet 1.

[0029] Although not shown in the figures, when sunlight comes from the side, the sliding curved plate 221 can be oriented to face the side of the helmet body 10, so that the umbrella is tilted to the side and sunlight from the side can be effectively avoided. This sliding curved plate 221 can be rotated in any direction 360°, and the sliding curved plate 221 can be rotated according to the direction of sunlight to change the orientation of the umbrella UB. This type of operation is extremely effective when staying in the same place for a long time, such as when fishing from a breakwater. In addition, sunlight can be effectively blocked when exposed to sunlight for a long time during outdoor work or leisure activities.

[0030] It is also possible to attach the umbrella UB to the first member 211 instead of the sunshade member fixing part 222. In that case, since the first member 211 is formed along the rotation axis, the inclination angle of the umbrella UB does not change even if the sliding curved plate 221 rotates. In the time period around 12 o'clock when the sunlight comes from a substantially vertical direction, it is also effective to attach the umbrella UB to the first member 211. Also, in case of rainy weather, it is effective to attach the umbrella UB to the first member 211. In this way, the umbrella UB can be selectively attached to the first member 211 or the sunshade member fixing part 222, and it becomes possible to effectively use the umbrella UB according to the outdoor weather, etc.

[0031] As described above, the helmet 1 and sunshade member fixing jig 20 of the first embodiment can block sunlight in response to changes in the direction of the sunlight, thereby improving the wearing comfort of the helmet wearer.

[0032] [Second embodiment] Next, a helmet 1 and a jig 20 for fixing a sunshade member according to a second embodiment of the present invention will be described with reference to Fig. 8 and Fig. 9. Fig. 8 is a perspective view for explaining the configuration of the jig 20 for fixing a sunshade member according to the second embodiment, and Fig. 9 is a perspective view showing a usage form. The same components as those in the first embodiment are given the same reference numerals in Figs. 8 and 9, and duplicated descriptions will be omitted below.

[0033] The sunshade member fixing jig 20 of the second embodiment additionally includes a fixing unit 23 for attaching an umbrella, which is a sunshade member, as shown in Fig. 8. This fixing unit 23 is composed of a base 231 and a sunshade member fixing part 232.

[0034] 9, the base 231 has a U-shaped recess V2. This U-shaped recess V2 fits into the groove C2 of the first member 211, thereby fixing the fixing unit 23 to the first member 211. The umbrella is fixed to the fixing unit 23 by inserting the umbrella handle into the insertion hole 232A and tightening the fixing screw 232B.

[0035] The fixing unit 23 may be fixed to the sunshade member fixing part 222 via the groove C3 instead of being fixed to the first member 211 via the groove C2. In either case, the angle of the umbrella changes as the rotating shaft member 21 rotates, and the sun can be blocked according to the direction of the sun's radiation.

[0036] [others] The present invention is not limited to the above-described embodiment, and includes various modified examples. For example, the above-described embodiment has been described in detail to clearly explain the present invention, and is not necessarily limited to those having all of the configurations described. In addition, it is possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. In addition, it is possible to add, delete, or replace a part of the configuration of each embodiment with another configuration.

[0037] For example, in the above-described embodiment, the shape of the sliding curved plate 221 is bent in one circumferential direction, but the shape of the sliding curved plate 221 is not limited to this, and various shapes can be adopted as long as it is capable of contacting the surface of the helmet body 10 at multiple points.

[0038] In addition, the example of using the fixing screws 224, 214 to fix the umbrella UB to the sunshade member fixing part 222 and the first member 211 has been described, but the form is not important as long as fixing is possible. For example, as shown in Fig. 10, a cylindrical member 251 may be fixed to the end of the handle UBX of the umbrella UB, and this cylindrical member 251 may be fixed to the sunshade member fixing part 222.

[0039] A protrusion 252 is provided around the cylindrical member 251, and this protrusion 252 fits into a fitting groove 241 formed on the inner circumference of the sunshade member fixing part 222. The cylindrical member 251 is inserted until the protrusion 252 passes the lower end of the fitting groove 241, and then rotated in any direction, thereby fixing the handle UBX of the umbrella UB to the sunshade member fixing part 222. In order to adjust the angle of the umbrella UB, the first member 211 and the sunshade member fixing part 222 can further be provided with a ball joint or the like.

[0040] In the above embodiment, the rotating shaft member 21 itself is configured to be rotatable relative to the helmet body 10, but the present invention is not limited to this, and the rotating shaft member 21 itself may be fixed to the helmet body 10, and the curved plate member 22 may be configured to be rotatable around the rotating shaft member 21.
