HEAD LAMP WITH COMFORTABLE BACK HEAD

Abstract

The disclosed invention relates to a head lamp including a front main band and a rear main band present along the sagittal suture, wherein a front surface of the rear main band in contact with the back head of the user is concave. The head lamp has improved wearing comfort and reduced failure rate.

Claims

1. A head lamp, comprising: a front main band and a rear main band present along a sagittal suture of a user, wherein the front main band is coupled with a front support band that extends in right and left directions in a middle of an overall length of the front main band, and is also coupled with the rear main band on a rear part such that the front main band and the rear main band are movable relative to each other, wherein the rear main band includes: an insert member inserted into the front main band; a movable member extending from the insert member to a battery box; and the battery box extending from the movable member, and wherein a front surface of the battery box is sufficiently concave and has a proper concave curvature such that, when the user wears the head lamp on their head, a most concave part in the front surface is located near a occipital protuberance of the user but is not in direct contact with the same, instead contacting surroundings of the occipital protuberance.

2. The head lamp according to claim 1, wherein the front surface of the battery box has a specific shape such that a horizontally widest part of the front surface is a part horizontally extending from the most concave part.

Description

DESCRIPTION OF DRAWINGS

[0015] FIG. 1 is a side view illustrating a state of wearing the conventional head lamp, which includes a main band to be fitted along the sagittal suture, on the head of a user.

[0016] FIG. 2 is a front-side perspective view illustrating the head lamp proposed in the present disclosure.

[0017] FIG. 3 is an exploded rear-side perspective view illustrating both of a front main band and a rear main band of the head lamp proposed in the present disclosure.

BEST MODE

[0018] Hereinafter, configurations of the conventional head lamp will be briefly described with reference to FIG. 1.

[0019] A light source 11 is a device to receive electricity and emit light and may be hinge-coupled to the front end 121 of a front main band 12. The front main band 12 may be formed in an overall S-shape from the top of the head to a part coupled with a front support band 13, and then, extended in a J-shape and hinge-coupled with the light source 11 at the end of the J-shape. The front support band 13 may be coupled at a starting portion of the J-shape and extend in a bow shape in right and left directions, while a rear main band 14 is inserted into a hole 122 on a rear part at which the S-shape starts. The rear main band 14 is formed in an overall smooth “>” shape in a side view and may include a battery box 15 provided on a lower part, wherein a rear support band 16 is coupled at the bottom of the battery box 15 and extends in a bow shape in right and left directions.

[0020] The front support band 13 may contact the forehead of the user while the rear support band 16 may contact a lower part of the back head, thereby facilitating safe fitting of the head lamp on the head of the user.

[0021] With respect of the head band, depending upon an insertion depth of the rear main band 15 into the hole 122 of the front support band 13, a distance between the front support band 13 and the rear support band 16 may vary and be adjusted to match a size of the head.

[0022] Hereinafter, embodiments of the present disclosure will be described in detail with reference to FIGS. 2 and 3.

[0023] FIG. 2 is a perspective view illustrating the head lamp proposed in the present disclosure. FIG. 3 is an exploded rear-side perspective view illustrating both a front main band and a rear main band in the head lamp proposed in the present disclosure. The description regarding from a light source 21 to the front main band 22 is substantially the same as that of the conventional head lamp.

[0024] The rear main band 25 is formed in an overall smooth “>” shape in a side view and may include: an insert member 251 provided on a front part, which is inserted into a hole 222 of the front main band 22 and adjusts a size of the head lamp; a movable member 252 starting from the rear end of the insert member 251 and extending in a circular arc form backward and downward; and a battery box 253 extending downward from the movable member 252. The battery box 253 is provided with a battery 254 to supply electricity to the light source 21 and a control member 255 to adjust electric current flowing from the battery to the light source 21.

[0025] A front surface 257 of the battery box 253 may generally have a diamond shape slightly longer in a vertical direction wherein right and left sides and the bottom side were cut out, and may be an overall concave and curved surface.

[0026] When the user wears the head lamp of the present disclosure on their head, the most concave part 258 of the front surface 257 may be located nearest the external occipital protuberance of the head without, however, being in direct contact with the same. The reason therefor is that the most concave part 258 is sufficiently deep as compared to a periphery part 259 [dotted part], and the periphery part 259 slightly spaced from the most concave part 258 may contact with the back head of the user. “d” in FIG. 2 is the depth of the most concave part. In this case, the widest protruding part in right and left directions in the front surface 257 is substantially a part horizontally extending from the most concave part 258.

[0027] Accordingly, as compared to the conventional head lamp including the rear support band 16 to support the lower part of the back head of the user, the head lamp with the above configurations may more widely support surroundings of the occipital protuberance of the user by the periphery part 259 in the front surface 257 of the rear main band 25, thereby accomplishing excellent wearing comfort and high stability.

[0028] The control member 255 may receive electric power from the battery 254, adjust electric current and supply electricity to the light source.

[0029] Consequently, the present embodiment has advantages over the conventional head lamp, including: improved wearing comfort at the front surface of the rear main band; high stability of the head lamp; and simple manufacturing process and reduction in failure rate owing to omission of a rear support band.
