Retractable razor assembly
View Patent ↗A retractable razor assembly includes a foldable blade support for mounting a razor blade or cartridge, and a mounting assembly connected to the blade support that can extend and retract the blade support from a handle and can stabilize the foldable blade support when extended. The adjustment assembly, when extended from the handle, remains substantially stationary to promote stability of the blade or cartridge, and to thereby promote comfort and safety during use of the razor assembly. A packaging system for containing and for displaying operation of the retractable razor includes at least a portion that provides visual inspection of the razor assembly. The packaging system further enables a consumer to physically interact with the razor assembly while contained therein. The packaging system permits a consumer to actuate the adjustment assembly to display its extension and retraction, and to provide a demonstration of the different operating states of the razor assembly.
1. A retractable razor assembly comprising:
a blade support including a first surface constructed and arranged to receive and to mount at least one blade assembly to the blade support;
a blade mounting assembly connected to the blade support including a first mounting element and a second mounting element, the first and second mounting elements moveably connected to one another via a tongue and groove combination including a longitudinal groove that the first mounting element defines along a portion of its length that is configured to receive at least a portion of a longitudinal tongue that the second mounting element defines along a portion of its length to couple the first and second mounting elements, the groove being further configured to permit the tongue to slide along at least a portion of the groove such that the second mounting element slides against the first mounting element that remains stationary relative to the second mounting element;
an upper portion of the first mounting element defining an opening configured to receive at least a portion of a fixing stem defined along a second surface of the blade support to pivotally connect the blade support to the first mounting element;
an upper portion of the second mounting assembly defining a protrusion and the second surface of the blade support defining a channel configured to receive at least a portion of the protrusion and to permit the protrusion to slide along a length of the channel;
an inner cylinder defining along a portion of its length two guide slots;
a protruding stem defined along an outer surface of each of the first and second mounting elements, the stems configured such that each guide slot of the inner cylinder accepts a portion of one stem when the blade mounting assembly is inserted within an interior of the inner cylinder;
an outer cylinder constructed and arranged to receive the inner cylinder and the blade mounting assembly, an interior surface of the outer cylinder defining a first spiral guide path and a second spiral guide path extending along a length of the outer cylinder, each of the first and second guide paths configured to receive at least a portion of one of the protruding stems, the first spiral guide terminating to a detent configured and disposed in an upper portion of the outer cylinder to receive at least a portion of the protruding stem along the second mounting element and to bias the portion of the protruding stem against the detent to provide resistance to movement; and
an actuating element constructed and arranged to operatively connect to the inner cylinder to join the actuating element to the outer cylinder and to rotate the inner cylinder within the outer cylinder,
wherein where the actuating element is rotated, the inner cylinder and the blade support assembly rotate vertically within the outer cylinder with the protruding stems sliding vertically along the first and second spiral paths and the guide slots of the inner cylinder, and where the blade support assembly emerges from the outer cylinder, the first mounting element completes its extension first with the second mounting element sliding along the groove of the first mounting element to extend its protrusion, and the protrusion gliding along the blade support channel and pushing the blade support vertically such that the blade support pivots about the fixing stem to a horizontal orientation relative to the outer cylinder and the detent receives the portion of the protruding stem of the second mounting element to lock the blade support in place.
2. The retractable razor assembly of claim 1 wherein the first mounting element is larger than the second mounting element in terms of size and weight to provide stability to the blade support.
3. The retractable razor assembly of claim 1 wherein the second mounting element protrusion slides along the blade support channel and pushes the blade support to a first open position at a horizontal orientation to the outer cylinder and to retract the blade support to a second retracted position at a vertical orientation to and within the outer cylinder.
4. The retractable razor assembly of claim 1 wherein the outer cylinder is sized and configured to enclose the blade support and the blade mounting assembly when the blade support is in the retracted position.
5. The retractable razor assembly of claim 1 wherein the first spiral guide path is longer than the second spiral guide path.
6. The retractable razor assembly of claim 1 wherein the guide slots of the inner cylinder have different widths from one another and the protruding stems of the first and second mounting elements have different sizes from one another.
7. The retractable razor assembly of claim 1 wherein the guide slots of the inner cylinder are diametrically opposed, and wherein the protruding stems of the first and second mounting elements are diametrically opposed.
8. The retractable razor assembly of claim 1 wherein the guide slots of the inner cylinder are disposed asymmetrically relative to one another, and wherein the protruding stems of the first and second mounting elements are disposed asymmetrically relative to one another.
9. The retractable razor assembly of claim 1 wherein the inner cylinder includes one or more tabs along an outer surface and the actuating element includes one or more notches, each notch adapted to receive at least a portion of one of the tabs.
10. The retractable razor assembly of claim 1 wherein the one or more tabs of the inner cylinder includes two tabs diametrically opposed and the one or more notches of the actuating element includes two notches diametrically opposed.
