Razor with handle having articulable joint
View Patent ↗A razor has a handle with an articulable joint intermediate the cutting blade and the portion of the handle grasped by a user. The joint includes a spring mounted around a pivot pin which in combination with a resilient sleeve disposed over the joint urges the joint to an initial position in resistance to a force applied by the user during shaving.
1. A razor comprising a head containing at least one blade, a handle connected to the head, the handle comprising a first portion and a second portion, the first portion being closer to the head than the second portion, one of the first portion and the second portion having an extension located in a recess in the other of the first portion and the second portion, spaced aligned apertures in the other portion and in the extension, a pivot pin extending through the spaced aligned apertures to form a joint whereby the first portion and the second portion are pivotally connected to each other at the joint and whereby a force created during use of the razor when the blade is pressed against skin of a user urges the first portion to rotate about the joint and move away from an initial non-use position, the extension being maintained surrounded by and totally confined within the other portion during rotational movement of the first portion, a resilient spring mounted around the pivot pin, the spring reacting around the first portion of the handle to create resistance to the force and to urge the first portion toward the initial position, a sleeve being tightly mounted over the first portion and the second portion and completely covering the joint, and at least a portion of the sleeve being resilient and being disposed against the first portion of the handle to create resistance to the force and to urge the first portion to the initial position whereby both the spring and the sleeve simultaneously create resistance to the force to urge the first portion to the initial position.
2. The razor of claim 1 wherein the resilient portion has greater resistance to the force than the resistance of the spring.
3. The razor of claim 1 , wherein the spring is a torsion spring having a central coil section and two oppositely extending legs with one of the legs in the first portion and the other of the legs in the second portion, and the coil section being positioned coaxially about the pivot pin.
4. The razor of claim 3 wherein the sleeve is retained in complete surface to surface contact with the first portion and the second portion.
5. The razor of claim 4 wherein the sleeve is mounted to the first portion and the second portion free of any external fastening elements.
6. The razor of claim 1 , wherein the sleeve has inner surfaces which are of smooth linear shape.
7. The razor of claim 1 , wherein the first portion and the second portion are collinear where they abut each other and the sleeve is straight.
8. The razor of claim 1 , wherein the first portion is curved and the second portion is straight, and the sleeve is located at and over and conforms to the curved first portion and the straight second portion.
9. The razor of claim 1 , wherein the resilient portion of the sleeve has a different resiliency than other portions of the sleeve.
10. The razor of claim 1 wherein the resilient portion of the sleeve is indented.
11. The razor of claim 1 , wherein the entire sleeve is resilient and provides the same resistance to the force as the resilient portion.
12. The razor of claim 1 wherein the sleeve is removably mounted over the joint.
13. A razor comprising a head containing at least one blade, a handle connected to the head, the handle comprising a first portion and a second portion, the first portion being closer to the head than the second portion, one of the first portion and the second portion having a forked extension, the forked extension including spaced tines, aligned apertures extending through the tines, the other of the first portion and the second portion having a recess, the forked extension being located in the recess, the other of the first portion and the second portion having spaced apertures aligned with the apertures extending through the tines, a pivot pin extending through the apertures of the tines and the apertures of the other portion to form a joint whereby the first portion and the second portion are pivotally connected to each other at the joint and whereby a force created during use of the razor when the blade is pressed against skin of a user urges the first portion to rotate about the joint and move away from an initial non-use position, a resilient spring mounted around the pivot pin and located between the tines in a central portion of the recess, the spring reacting against the first portion of the handle to create resistance to the force and to urge the first portion toward the initial position, a sleeve being tightly mounted over the first portion and the second portion and completely covering the joint, and at least a portion of the sleeve being resilient and being disposed against the first portion of the handle to create resistance to the force and to urge the first portion toward the initial position whereby both the spring and the sleeve simultaneously create resistance to the force to urge the first portion to the initial position, and wherein the resilient portion has greater resistance to the force than the resistance of the spring.
14. The razor of claim 13 wherein the entire sleeve is resilient.
15. A razor comprising a head containing at least one blade, a handle connected to the head, the handle comprising a first portion and a second portion, the first portion being closer to the head than the second portion, one of the first portion and the second portion having a forked extension, the forked extension including spaced tines, aligned apertures extending through the tines, the other of the first portion and the second portion having a recess, the forked extension being located in the recess, the other of the first portion and the second portion having spaced apertures aligned with the apertures extending through the tines, a pivot pin extending through the apertures of the tines and the apertures of the other portion to form a joint whereby the first portion and the second portion are pivotally connected to each other at the joint and whereby a force created during use of the razor when the blade is pressed against skin of a user urges the first portion to rotate about the joint and move away from an initial non-use position, a resilient spring mounted around the pivot pin and located between the tines in a central portion of the recess, the spring reacting against the first portion of the handle to create resistance to the force and to urge the first portion toward the initial position, a sleeve being tightly mounted over the first portion and the second portion and completely covering the joint, and at least a portion of the sleeve being resilient and being disposed against the first portion of the handle to create resistance to the force and to urge the first portion toward the initial position whereby both the spring and the sleeve simultaneously create resistance to the force to urge the first portion to the initial position.
16. A kit comprising a razor and a set of a plurality of sleeves, each of the sleeves being selectively and removably mountable on the razor, the razor comprising a head containing at least one blade, a handle connected to the head, the handle comprising a first portion and a second portion, the first portion being closer to the head than the second portion, one of the first portion and the second portion having a forked extension, the forked extension including spaced tines, aligned apertures extending through the tines, the other of the first portion and the second portion having a recess, the forked extension being located in the recess, the other of the first portion and the second portion having spaced apertures aligned with the apertures extending through the tines, a pivot pin extending through the apertures of the tines and the apertures of the other portion to form a joint whereby the first portion and the second portion are pivotally connected to each other at the joint and whereby a force created during use of the razor when the blade is pressed against skin of a user urges the first portion to rotate about the joint and move away from an initial non-use position, a resilient spring mounted around the pivot pin and located between the tines in a central portion of the recess, the spring reacting against the first portion of the handle to create resistance to the force and to urge the first portion toward the initial position, each of the sleeves when selectively mounted on the razor being tightly mounted over the first portion and the second portion and completely covering the joint, and at least a portion of the sleeve when selectively mounted on the razor being resilient and being disposed against the first portion of the handle to create resistance to the force and to urge the first portion toward the initial position whereby both the spring and the sleeve when selectively mounted on the razor simultaneously create resistance to the force to urge the first portion to the initial position, and the plurality of the sleeves having differing resiliency characteristics.
