ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a stage-by-stage tightness-adjustable hair clip structure which can be opened at one single end or at both ends. The tightness of the hair clip can be adjusted stage by stage according to the amount of a user's hair.
Most of the conventional hair clips are composed of a base plate, a leaf spring and a clip plate. Such hair clips are openable at one end rather than at both ends.
The earliest hair clip pertains to a one-stage hair clip which cannot be adjusted in tightness so that a user with less hair or more hair can hardly suitably use such hair clip. A multi-stage hair clip has been developed to solve this problem. However, such hair clip can be only opened at one end rather than at both ends.
Moreover, it is known that the consumers include right-handed users and left-handed users which use the hair clip by different way. The existing hair clips are all designed for the right-handed users, while the requirement of the left-handed users is always neglected. In addition, due to the limitation of the opening direction of the hair clip, the conventional hair clips are equipped with decorative articles in one single direction. Therefore, it is necessary to provide a hair clip which can be opened at both ends so that the requirements of both the right-handed users and left-handed users can be satisfied.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a stage-by-stage tightness-adjustable hair clip structure including a base plate, a leaf spring and a clip plate. Each end of the base plate is disposed with a pair of latch boards. Each end of the leaf spring is disposed with a pair of fork legs. Each end of the clip plate is disposed with a pair of latch lugs. Accordingly, the hair clip are openable at both ends. The present invention includes five different aspects as follows:
1. The latch board of the base plate is disposed with a row of intercommunicated latch holes and the latch lug of the clip plate is disposed with a tenon for selectively inserting into the latch holes and assembling the clip plate with the base plate, whereby the tightness of the hair clip can be adjusted as necessary.
2. A latch hook extends from the latch board of the base plate and the latch lug of the clip plate is disposed with an engaging socket, whereby the latch hook can be hooked in the engaging socket to assemble the clip plate with the base plate and the tightness between the clip plate and the base plate is adjustable.
3. A latch arm extends from the latch board of the base plate for engaging with the engaging socket of the latch lug of the clip plate so that the clip plate is assembled with the base plate and the tightness between the clip plate and the base plate is adjustable.
4. The base plate is disposed with a rack and the leaf spring is also disposed with a cooperative rack, whereby a tenon of the clip plate can be selectively engaged with the racks to assemble the clip plate with the base plate and the tightness between the clip plate and the base plate is adjustable.
5. A rack extends from the fork leg of the leaf spring for engaging with the engaging socket of the clip plate, whereby the clip plate is assembled with the base plate and the tightness between the clip plate and the base plate is adjustable.
The openable end of each of the above aspects can be replaced by a conventional pivot end to form a hair clip which is openable only at one end.
The present invention has the following advantages:
1. The hair clip of the present invention can be opened at both ends in two directions so that both right-handed users and left-handed users can use the hair clip.
2. The tightness of the hair clip can be adjusted stage by stage according to the amount of the user's hair.
3. The decorative articles can be disposed on the hair clip in at least two directions.
The present invention can be best understood through the following description and accompanying drawing, wherein:
