Patent Application
20060129187
This invention relates to a tweezers comprising a pair of pincers or clamping mechanism on both ends, the pincers having different tips for different purpose.
Current tweezers only have one head on a body with a stationary and a moving end. The body is generally constructed from two identical elongated thin flat sheets. The two elongated flat sheets are fused together at one end to form the stationary end resulting in a pair of free opposing ends. The fusion at one end causes the opposite end to open up or space apart, consequently, allowing movement at this end as pressure by the fingers for example, is exerted or released at the outside surfaces of the elongated flat sheets proximal to the free end.
There are different types or applications of tweezers, there are those for cosmetic purposes, usually for plucking unwanted hair, there are those used in surgery for holding or gripping tissues, blood vessels, organs and the like, there are those used in dentistry for clamping a tooth, there are those used in weaving and embroidery for plucking or inserting a thread, etc. In these applications, each tweezers has its own head. Head in this application is used to denote a pincer of the tweezers with its tips. None of these tweezers offer the flexibility of having two heads instead of one. With individual tweezers having only one head, one has to carry or prepare each individual tweezers needed. Also occasions when only one tweezers with one head is at hand, one has to adjust and make do with what one has causing sub-optimal functions.
It is therefore an object of this invention to provide a tweezers with more than one head for variable purpose or function.
It is also an object of this invention to minimize the number of individual tweezers needed to carry on a desired function or operation.
It is a further object of this invention to provide a tweezers with interchangeable heads.
This invention relates to a double headed tweezers, comprising a body having a pair of elongated movable pincers on one end and another pair of elongated movable pincers on an opposite end, the body formed from two flat elongated units of identical length fused stationarily at a location between the opposing movable pincers, each pincers having a tip, the tip opening and closing according to pressure exerted on the pincers. The tips at the end of the pincers are of various sizes and are shaped for a desired function. The double headed tweezers is fused together by welding or staking. The pincers can be formed differently, one way is from two straight flat elongated units, another, from two curved elongated units and another from one straight and one curved elongated units. A wide top and bottom surfaces of different geometric shape is recommended for the tweezers.
Instead of welding or staking a portion of the body between the opposing pincers with their corresponding tips, the double headed tweezers can have a connector having an opening at each lateral end; a first tweezers having a pincer with a tip on one end and a connecting piece on another end inserting into the opening of one lateral end of the connector; and, a second tweezers having a pincer with a tip on one end and a connecting piece on another end inserting into the opening of the other lateral end of the connector. The tips of the first and second tweezers are of various sizes and are shaped according to a desired function. The pincers are recommended to have a wide top surface of different geometric shape. The connector allows one tweezer to be replace by another tweezer thereby making the different tips of the tweezers interchangeable.
Other embodiments of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein it shows and describes only certain embodiments of the invention by way of illustration. As will be realized, the invention is capable of other and different embodiments and its several details are capable of modification in various other respects, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not as restrictive.
Aspects of the present invention are illustrated by way of example, and not by way of limitation, in the accompanying drawings, wherein:
The detailed description represented herein is not intended to represent the only way or the only embodiment in which the claimed invention may be practiced. The description herein is provided merely as an example or examples or illustrations of the claimed invention and should not be construed as the only way or as preferred or advantageous over other embodiments or means of practicing the invention. Any tweezers with a multiple head, that is more than one in a single body is within the scope of this invention. The detailed description includes specific details to provide a thorough understanding of the claimed invention and it is apparent to those skilled in the art that the claimed invention may be practiced without these specific details. In some instances, well known structures and devices are shown in block diagrams or drawn with broken lines in order to either avoid obscuring the main concepts of the invention or to show the relationship of one part to the other.
A simple way of manufacturing a two headed tweezers is to take two flat elongated units of a desired length, for example, a 4-5 inch length is sufficient to have a tweezers with two heads at both ends; cut these units to form a body 2 of the tweezers according to the desired shape of the pincers 3; shape the ends of the pincers to the desired tip 5; and fuse at a location between the opposing pincers to make the fusion point stationary while keeping the two opposing pincers free to move. The tweezers are fused together for example by welding or by staking. Other means of fusion are acceptable so long as the two elongated units are kept connected with each other, for example, the two flat elongated units forming the body of the tweezers can also be joined by screws such as that shown in
As shown in
With two different tips in one tweezers, one can use one tip and simply flip the tweezers and use the other tip. For example, one can pluck the hair with the square tip 6 at an area above or below the eyebrows, and then simply flip the tweezers to pluck the short hair or those on the borders to shape the eyebrows with the pointed tip 7 without putting one tweezer aside and looking for the other tweezer. Alternately, the two heads can snap in and out from two sides of a connector 10 as shown in
While the embodiments of the present invention have been described, it should be understood that various changes, adaptations, and modifications may be made therein without departing from the spirit of the invention and the scope of the claims.
