ABSTRACT:
BACKGROUND OF THE INVENTION
(1) Field of the Invention
The invention pertains to a hair removal or depilatory device for use on the body. In particular, the device pertains to a hand-held and manually manipulated depilatory device. These types of depilatory devices have at least one abrasive surface. The depilatory device removes the hair by rubbing or buffing the abrasive surface against the body where hair removal is desired. The result of using the device allows hair removal without pain, odor, chemicals or mess.
(2) Description of the Related Art
Over the years, many devices have been developed to remove unwanted hair and skin from the body via an abrasive means. The abrasive surfaces of the prior art devices are typically symmetrical along both a longitudinal axis in length and a lateral axis in width. The contour of the abrasive surface is usually smooth and without any protrusions or projections. The prior art devices typically are hand-held and manipulated and accordingly incorporate some method for gripping and handling the device via the hand or fingers. Additionally, the prior art devices' abrasive surface is typically flat or planer although, some of the prior art devices are comprised of a curved or rounded abrasive surface.
As stated earlier, the prior art devices are typically symmetrical along both their longitudinal length and lateral width. A disadvantage of the symmetry is that both sides serve the same purpose as the other in regards to its ability to conform to and reach areas on the body.
Prior art devices typically have an abrasive surface whose contour is smooth or gently curving and do not have any projections or protrusions. These devices usually have an abrasive surface that has either rounded ends, squared ends, or squared ends with rounded corners. A disadvantage of these prior art configurations is that the contours of the abrasive surface do not allow for convenient access to and removal of hair or skin in confined or difficult to reach crevices or locations upon the body. Additionally, accurate removal of hair from locations where maintaining a defined hairline is desirable is difficult with the prior art devices. These disadvantages of the prior art devices can be overcome by a device having ends of different sizes to allow for the removal of hair in large unobstructed areas with the larger end while the user can utilize the smaller end for tighter or more confined, difficult to reach locations of hair removal. Additionally, the different size ends would allow the use of the smaller end for hair removal where accuracy is more important than quickness.
Prior art devices typically have a hand or finger hold. These can range from allowing the user to hold and manipulate the device with a few fingers to requiring the use of the entire hand. Some prior art devices have handles that are collapsible or removable. The prior art devices typically utilize a rigid hand or finger hold. A disadvantage of these prior art devices' hand or finger holds is that the shape or configuration of the hand or finger hold is not always conducive to sustained gripping and manipulation. Additionally, the hand or finger holds of the prior art devices that are flexible are not contoured to conform to the configuration of the fingers. Thus continued manipulation of the device can lead to fatigue or pain in the hand or fingers. These disadvantages of the hand or finger holds of the prior art can be overcome by designing a finger hold that is flexible and/or conforms to the contours of the fingers.
SUMMARY OF THE INVENTION
The present invention provides a device for removing hair from the body, but may also be employed in any application that requires removal of hair or skin cells from the body via an abrasive method. The device is basically comprised of a body, a finger hold, and an abrasive surface. The device has a bottom surface that is generally flat. The bottom surface may also be curved or rounded and still perform the desired function of the device. The abrasive surface of the device can be integral to the bottom surface or can be a separate abrasive sheet that can be secured to the bottom surface of the device. The use of a separate abrasive sheet allows for the removal of worn-out abrasive sheets and replacement with a new abrasive sheet thus increasing the useful life of the device. Use of a removable and replaceable abrasive sheet further allows for the device to be used in applications requiring differing levels of abrasion. That is, different abrasive sheets can employ differing levels of coarseness depending upon the desired application, thereby increasing the versatility of the device.
In the preferred embodiment, the abrasive sheet has an adhesive backing that is utilized to secure the abrasive sheet to the bottom surface of the device. However, in alternate embodiments, the sheet may be secured to the bottom surface by other suitable means.
The present device has opposing ends of unequal surface area. The advantage of having unequal surface areas on opposing ends of the device is that it allows for more efficient removal of hair from easily accessible and large areas of the body by utilizing the end having a larger surface area. The smaller surface area or narrower end can then be utilized in areas requiring finer or closer attention to detail where the accuracy of the hair removal is more important than the quickness of hair removal.
The device has an abrasive surface whose contour includes generally pointed projections. The generally pointed projections of the abrasive surface allows for the removal of hair in difficult to reach locations on the body. The contour allows the user to reach confined areas or crevices on the body with the generally pointed projections of the abrasive surface that can not be reached by an abrasive surface having the contours of the prior art. The device also has generally pointed corners. The generally pointed corners also facilitate hair removal in difficult to reach locations on the body. In addition, these abrasive projections and corners also allow for the accurate removal of hair from areas where the removal of hair from specific locations and not other locations is important, such as where a well defined hairline is desired.
The finger hold of the device is designed to facilitate the rubbing and buffing motion employed in the removal of hair or skin. The finger hold is tapered inwardly as it extends longitudinally to facilitate comfort and the transfer of force from the fingers to the device. The finger hold also tapers inwardly as it extends upwardly from the top surface of the device. This tapering also aides in the comfort experienced by the user when manipulating the device by providing a secure grip on the device. The finger hold is recessed in the middle of the device where the bottom surface of the device is at its smallest lateral width. The finger hold smallest lateral width dimension, is laterally smaller than the smallest lateral width dimension of the bottom surface immediately below the finger hold. From the location on the finger hold where it is at its smallest lateral width, the finger hold flares laterally outwardly as it extends longitudinally towards the opposing ends of the device. The recessed finger hold allows for removal of hair from tight or confined areas without the user's fingers obstructing or interfering with the ability of the abrasive surface to reach these difficult areas. The finger hold is also designed with generally parallel webbed members or grips that deform from the pressure of the user's fingers to create a more comfortable and efficient means to manipulate the device.
The device is made of a pliable material such as rubber or any other suitable material. The pliable nature of the material allows the device to deform in order to conform to the surface features and contours of the body where hair or skin removal is desired. The device may also be made of a rigid material, such as a hard plastic or any other suitable material, where deformation of the device and
