The present invention relates generally to cosmetic, surgical, dental and hobby tools and implements. More particularly, the present invention relates to tweezers.
Human hands are very useful for many tasks of manual manipulation of physical objects, but some objects are too small to handle easily bare-handed. When an object too small to be handled easily with human hands is encountered, tweezers are typical instruments that is useful to such a task. Typical tweezers are a pinching implement making use of two third-class levers connected at one fixed end, the fulcrum point of each lever, with pinching tips at the opposite end.
Tweezers have many uses. One common use for tweezers is in cosmetics and beauty, including plucking pair from the face or eyebrows, applying fake eyelashes, and fixing jewelry. Other cases of manipulating small objects for which tweezers are useful or essential are removing splinters, manipulating surface-mount electronic parts and small mechanical parts for models and precision mechanisms such as watches. Other specialized uses for tweezers include picking out gold flakes in gold panning, and removing bones from fish fillets in a process known as pin boning. Tweezers may also be used in various medical and dental procedures, among many other applications.
Tweezers can have many different types of tips for different applications. For example, tweezer tips typically used for cosmetics and beauty include slanted tip, pointed tip, pointed-slant tip, round tip, flat tip, and jagged tip. Each one is more particularly suited to various applications than others, such as removing different lengths and types of hairs, applying cosmetic products such as fake eyelashes, removing splinters, and providing various degrees of precision and control. Tweezers also have many applications in dental and surgical fields, such as picking up gauze and holding needles in the operating room.
The object of the present invention is to provide a double-ended tweezer that is able to combine multiple types of tweezer tips for multiple applications in a single implement.
All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention. The present invention is to be described in detail and is provided in a manner that establishes a thorough understanding of the present invention. There may be aspects of the present invention that may be practiced without the implementation of some features as they are described. It should be understood that some details have not been described in detail in order to not unnecessarily obscure focus of the invention.
The present invention is a double ended tweezer for multifunction purposes. Different types of tweezer ends are more suited to different applications. The double ended nature of the present invention allows a single tweezer implement to comprise two types of tweezer tips in order to perform two or more tweezer related functions.
Referring to
In the preferred embodiment of the present invention, the first lateral arm 1 and the second lateral arm 2 each comprise a first side 11 and a second side 12. The first side 11 and the second side 12 of the first lateral arm 1 and the second lateral arm 2 are oriented parallel to the central axis 6. The first side 11 and the second side 12 are positioned opposite and parallel to each other on the first lateral arm 1 and the second lateral arm 2. In the preferred embodiment, the first side 11 and the second side 12 of the first lateral arm 1 and the second lateral arm 2 are flat, or substantially flat. The first lateral arm 1 and the second lateral arm 2 may be embodied with slight curves, inflection points or other geometric features that facilitate ease of use or aesthetics, but the first lateral arm 1 and the second lateral arm 2 are substantially flat, thin and elongated.
The connecting arm 3 is connected at an arm connecting angle 31 to the first lateral arm 1 and the second lateral arm 2. The connecting arm 3 is preferably connected to the second side 12 of the first lateral arm 1 adjacent to the first end 7, and the connecting arm 3 is connected to the first side 11 of the second lateral arm 2 adjacent to the second end 8. In the preferred embodiment of the present invention, the arm connecting angle 31 is an acute angle measured clockwise from the second side 12 of the first lateral arm 1 to the connecting arm 3 and counterclockwise from the first side 11 of the second lateral arm 2 to the connecting arm 3. This arrangement provides squeezing functionality at both the first end 7 and the second end 8.
In the preferred embodiment, the first pinching tip pair 4 and the second pinching tip pair 5 each comprise a first tip 41 and the second tip 42. The functionality of the present invention is realized when a user applies compressive force to the first lateral arm 1 and the second lateral arm 2 near the first end 7 or second end 8 in order to bring together the first tip 41 and the second tip 42, thereby clasping an object between the first tip 41 and the second tip 42 for manual manipulation.
The first tip 41 of the first pinching tip pair 4 is connected to the first lateral arm 1 at the first end 7, and the second tip 42 of the first pinching tip pair 4 is connected to the second lateral arm 2 at the first end 7. Similarly, the first tip 41 of the second pinching tip pair 5 is connected to the first lateral arm 1 at the second end 8, and the second tip 42 of the second pinching tip pair 5 is connected to the second lateral arm 2 at the second end 8.
The first pinching tip pair 4 and the second pinching tip pair 5 may take a number of different forms that are more appropriate for various specialized applications. In one embodiment, the first pinching tip pair 4 is a slanted tweezer end pair 110. In another embodiment, the first pinching tip pair 4 is a straight tweezer end pair 112. In another embodiment, the first pinching tip pair 4 is a curved head pair with straight ends 114. In another embodiment, the first pinching tip pair 4 is a curved head pair with slanted ends 116. In another embodiment, the first pinching tip pair 4 is a nail clipper head 118.
Additionally, in one embodiment the second pinching tip pair 5 is a tweezer nipper end pair 120. In another embodiment the second pinching tip pair 5 is a pointed end pair 122. In another embodiment, the second pinching tip pair 5 is a slanted tweezer end pair 110. In another embodiment the second pinching tip pair 5 is a curved head pair with straight ends 114. In another embodiment the second pinching tip pair 5 is a curved head pair with slanted ends 116.
Combining the above embodiments for the first pinching tip pair 4 and the second pinching tip pair 5 results in a plurality of desired embodiments for the present invention. In a first preferred embodiment of the present invention shown in
In a ninth embodiment shown in
It should be noted that although several specific embodiments comprising different combinations of pinching tips have been disclosed, any other desired combination of types of pinching tips may also be comprised in the present invention.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
The current application is a continuation in part of U.S. Design patent application Ser. No. 29/521,395 filed on Mar. 23, 2015.
