Abstract
A shaver includes an improved locking mechanism for securing a shaving head to the shaver while allowing for simple and convenient removal thereof. The shaver further includes an adjustable shaver head that effectively follows the contours of the face or body. The shaver can be extended to use with a backshaver that has a first handle portion connected to a second handle portion by a joint assembly that allows the handle portions to be adjusted to varying angles and locked at a desired angle.
Claims9
A shaver comprising:
- a shaver head having a lower end that has a recess, and a circular raised ring extending from the lower end having at least two spaced-apart L-shaped grooves;
- and
- a handle base having a mounting base that includes a circular groove having at least two spaced-apart bumps provided in a wall of the circular groove, with each of the bumps being fitted inside a corresponding L-shaped groove when the shaver head is connected to the handle base, and the mounting base further including a locking projection that is fitted inside the recess of the shaver head when the shaver head is connected to the handle base.
A shaver head comprising:
- a head portion that includes a shaving element, the head portion having a lower end, with a connection shaft extending from the lower end, the connection shaft having opposing transverse rotating shafts extending therefrom, and opposing baffles adjacent the rotating shafts and extending from the connection shaft;
- and
- a base portion having a housing, with positioning racks extending in the housing to receive corresponding rotating shafts for rotation therein, the base portion further including a plurality of springs positioned adjacent the positioning racks, and each spring aligned with a corresponding baffle so as to be biased against the corresponding baffle for providing a restoring force to the circumferential rotation of the connection shaft.
A backshaver, comprising:
- a first handle portion having a first end and a second end, with a shaver head carried at the first end;
- a second handle portion;
- a joint assembly comprising:
- a housing having a first joint housing connected to the first handle portion and a second joint housing connected to the second handle portion, the first and second joint housings pivotable with respect to each other;
- a first circle of inner teeth arranged inside the first joint housing;
- two blocks retained inside the first joint housing, each block having one group of raised teeth that is adapted to be meshed inside certain teeth of the first circle of inner teeth;
- a biasing element arranged between the blocks and biasing the blocks away from each other to push the groups of raised teeth against the certain teeth of the first circle of inner teeth;
- a second circle of inner teeth arranged on an opposite side of the first circle of inner teeth;
- a raised tooth plate provided inside the second circle of inner teeth, the raised tooth plate having at least two groups of teeth along its periphery, the raised tooth plate movable up and down with respect to the second circle of inner teeth to first and second positions, respectively, the at least two groups of teeth of the raised tooth plate being meshed with certain teeth of the second circle of inner teeth in the first position, and the at least two groups of teeth of the raised tooth plate being separated from the teeth of the second circle of inner teeth in the second position;
- and
- a driving block that is secured to the raised tooth plate, the driving block moving the raised tooth plate up and down with respect to the second circle of inner teeth.
