Description:
BACKGROUND OF THE INVENTION
[0001]1. Field of the Invention
[0002]The present invention relates to a hair clamping device and, more particularly, to a hair-clamping device that provides enhanced hair clamping effect and allows convenient operation.
[0003]2. Description of the Prior Art
[0004]FIG. 9 shows a conventional hair clamping member 1' including an elastic band 11' and an engaging member 12' coupled between two ends of the elastic band 11' to form a loop. The hair clamping member 1' can be folded to form a couple of loops to reduce the opening for clamping hair. However, greater force is required to enlarge the opening for receiving hair of a user or removing the band 11' from the hair of the user, leading to inconvenient operation. Furthermore, the hair is liable to be torn off during removal of the band 11' due to improper operation.
[0005]FIGS. 10 and 11 show another conventional hair clamping member 2' integrally formed of plastic material. A plurality of teeth 21' are formed on an end of the hair clamping member 21'. A coupling hole 22' is formed in the other end of the hair clamping member 21'. The hair clamping member 21' can be bent, and the end can be inserted through the coupling hole 22' until one of the teeth 21' is engaged with the coupling hole 22'. Such a hair clamping member 2' allows adjustment of clamping tightness as well as easy operation. However, the hair clamping member 2' risks falling from the hair of the user, for the hair clamping member 2' is not resilient and the human hair is oily.
[0006]Hair clamping can also be achieved by tying, which is however inconvenient in operation.
BRIEF SUMMARY OF THE INVENTION
[0007]An objective of the present invention is to provide a hair clamping member that provides enhanced hair clamping effect and allows convenient operation.
[0008]A hair clamping device according to the preferred teachings of the present invention includes a base having a bottom wall and two parallel, spaced sidewalls on two opposite sides of the bottom wall, defining a compartment between the bottom wall and the two sidewalls.

DETAILED DESCRIPTION OF THE INVENTION
[0027]A hair clamping device according to the preferred teachings of the present invention is shown in FIGS. 1-8 of the drawings. According to the preferred form shown, the hair clamping device includes a base 1, a cover 2, an elastic element 3, an engaging plate 4, and a strap 5. The base 1 is made of rigid material and includes a bottom wall 11 and two parallel, spaced sidewalls 12 on two opposite sides of the bottom wall 11, defining a compartment 13 between the bottom wall 11 and the sidewalls 12. The bottom wall 11 includes a strap coupling portion 14 in the most preferred form shown as a slot. The sidewalls 12 include two aligned pivot holes 15.
[0028]The cover 2 is mounted on top of the compartment 13, leaving an opening 131 in an end of the compartment 13. The cover 2 includes two parallel, spaced lugs 21 each having a pin hole 25 aligned with the pivot holes 15 of the base 1. A pivotal member 16 in the most preferred form shown as a pin is extended through the pivot holes 15 of the sidewalls 12 and the pin holes 25 of the cover 2 to pivotally connect the cover 3 with the base 1. The cover 2 includes an engaging portion 22 on an inner face thereof facing the compartment 13. In the most preferred form shown, the engaging portion 22 is a protrusion having an inclined face 23 at an acute angle with the cover 2. An ornament 24 is mounted on an outer face of the cover 2 opposite to the inner face.
[0029]According to the most preferred form shown, the elastic element 3 is a torsion spring including a coil portion 31 mounted around the pivotal member 16 and first and second tangs 32 and 33 respectively attached to the bottom wall 11 and the inner face of the cover 2. The elastic element 3 biases the cover 2 to cover the base 1 without covering the opening 131.
[0030]The engaging plate 4 is made of rigid material and includes an insertion portion 42 having a coupling portion. According to the most preferred form shown, the coupling portion includes a plurality of parallel coupling holes 421, 422, 423 spaced from one another in a longitudinal direction of the engaging plate 4. A strap engaging portion 41 in the most preferred form shown as a slot is provided on an end of the engaging plate 4. An inclined face 43 is formed on the other end of the engaging plate 4 and at an acute angle with the engaging plate 4. The strap 5 is made of resilient material and includes first and second ends respectively coupled to the strap engaging portions 14 and 41.
[0031]In use, the strap 5 is wound around hair of a user (FIG. 6), with the engaging plate 4 inserted via the opening 131 of the base 1 into the compartment 13. The inclined face 43 of the engaging plate 4 is moved across the inclined face 23 of the cover 2 such that the cover 2 moves away from the base 1 (FIG. 3). When the coupling hole 421 is moved to a position aligned with the engaging portion 22 of the cover 2, the engaging portion 22 is moved by the resiliency of the elastic element 3 into the coupling hole 421 to reliably clamp the hair of the user in a loop formed by the strap 5. Since the strap 5 is made of resilient material, disengagement of the hair clamping device from the hair of the user is avoided.
[0032]It can be appreciated that the clamping tightness of the hair clamping device can be adjusted by engaging the engaging portion 22 of the cover 2 with another coupling hole 422, 423 (see FIG. 5). The ornament 24 on the cover 2 can cover the cover 2 and the base 1 to provide aesthetically pleasing effect.
[0033]When removal of the hair clamping device from the hair of the user is required, the user holds the cover 2 or the ornament 24 and moves the cover 2 away from the base 1, disengaging the engaging portion 22 from the coupling holes 421, 422, 423 and allowing removal of the engaging plate 4 from the base 1. The resiliency of the strap 5 assists in rapid removal of the engaging plate 4 from the base 1, providing enhanced operational convenience. Operation of moving the cover 2 away from the base 1 by holding the ornament 24 also assists in operational convenience.
[0034]The pivotal connection between the base 1 and the cover 2 can be arranged at the other end of the base 1 opposite to the strap coupling portion 14 and at the other end of the cover 2, with the elastic element 3 mounted around the pin 16 in a corresponding position. The strap 5 can be coupled to the base 1 and the engaging plate 4 by other suitable methods including but not limited to bonding. The ornament 24 can be omitted. Furthermore, the engaging plate 4 can include only one coupling hole.
[0035]Thus since the invention disclosed herein may be embodied in other specific forms without departing from the spirit or general characteristics thereof, some of which forms have been indicated, the embodiments described herein are to be considered in all respects illustrative and not restrictive. The scope of the invention is to be indicated by the appended claims, rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
