Abstract

Handle is provided for battery operated razors. In some implementations, the handle includes a simple, efficient mechanism for both securing a battery cover to the handle of a razor and at the same time providing a high reliability electrical contact between the battery and electronics of the razor. The mechanism includes a closing system, including a first conductive component slidably attached within the battery cover and biased toward a predetermined axial position, and a second conductive component secured to the interior wall of the grip portion. The first conductive component is configured to interact with the second conductive component and move axially within the battery cover during engagement of the battery cover with the grip portion.

First claim

1 - 11 . (canceled)

12 . A battery operated razor comprising:
a grip tube having an exterior wall defining a chamber having an interior wall and an open end; a battery cover having an exterior wall defining a cavity having an interior wall and an open end, the battery cover removably mounted on the grip tube, wherein the grip tube chamber and battery cover cavity are configured to contain one or more batteries, and a closing system comprising a first threaded portion at the grip tube chamber open end and a second threaded portion at the battery cover cavity open end mating with the first threaded portion, the closing system including a first conductive component and a second conductive component, the first conductive component is slidably attached to the interior wall of the battery cover cavity and biased toward a predetermined axial position, the second conductive component is secured to the interior wall of the grip tube chamber; the first conductive component comprises an L-shaped member extending circumferentially about the interior wall of the battery cover cavity proximate the battery cover open end providing a contact surface facing the open end, the first conductive component L-shaped member comprises a first end and a second end opposite the first end, the first end having a vertical leg extending axially from the contact surface toward the open end of the cavity forming a first conductive component end stop and the second end having a kinked portion proximate the second end extending axially away from the contact surface toward the battery cover open end; the second conductive component comprises an L-shaped member extending circumferentially about the interior wall of the grip tube chamber and providing a contact surface facing the grip tube chamber open end, the L-shaped member comprises a first end and a second end opposite the first end, the first end having a vertical leg extending axially from the contact surface away from the grip tube chamber open end forming a second conductive component end stop, the second end having a protrusion proximate the second end extending from the contact surface, toward the grip tube chamber open end; wherein during attachment of the battery cover to the grip tube, the first conductive component contact surface interfaces with the second conductive component contact surface wherein the kinked portion of the first conductive component contact surface interferes with the second conductive component contact surface deflecting the first conductive component axially as the kinked portion slides circumferentially along the contact surface of the second conductive component producing an audible click as the kinked portion slides over the protuberance on the second conductive component contact surface and contacting the first conductive component end stop with the second conductive component end stop subsequent to the audible click.

13 . The razor of claim 12 wherein the first conductive component comprises a first end, a second end and an elongate middle section therebetween, wherein the L-shaped member is disposed at the first end, the elongate middle section is slidably attached to the interior wall of the battery cover cavity and the second end includes a spring mechanism biasing the first conductive member toward the predetermined axial position.

14 . The razor of claim 13 wherein the spring mechanism comprises an axial spring disposed between the second end and the battery cover cavity.

15 . The razor of claim 13 wherein the spring mechanism is structurally integral with the second end.

16 . A battery operated razor comprising:
a grip tube having an exterior wall defining a chamber having an interior wall and an open end; a battery cover having an exterior wall defining a cavity having an interior wall and an open end, the battery cover removably mounted on the grip tube, wherein the grip tube chamber and battery cover cavity are configured to contain one or more batteries, and a closing system comprising a male threaded portion on the exterior wall of the grip tube at the grip tube chamber open end and a female threaded portion on the interior wall of the battery cover cavity open end, the closing system including a first conductive component slidably attached to the interior wall of the battery cover cavity and biased toward a predetermined axial position, and a second conductive component secured to the interior wall of the grip tube chamber, the first conductive component and the second conductive component are configured to interact during engagement of the battery cover with the grip tube wherein the first conductive component moves axially within the battery cover during engagement; the first conductive component comprising a first end, a second end and an elongate middle section therebetween, the elongate middle section is slidably attached to the interior wall of the battery cover, the first end comprises an L-shaped member, the L-shaped member extends circumferentially providing a contact surface toward the open end of the battery cover cavity arranged perpendicular to the elongate middle section, the L-shaped member comprises a vertical leg extending axially toward the open end of the cavity at a first end forming a first conductive member end stop and a kinked portion near a second end opposite the first end rising above the contact surface toward the open end of the cavity, the second end forms a U-shaped portion having a first leg extending radially away from the elongate middle section to a bend and a second leg extending from the bend parallel to the first leg, back towards the elongate middle section, the second leg is attached to the interior surface of the battery cover allowing the first leg to deflect axially and to bias the first conductive component as it moves axially within the battery cover; the second conductive component comprising an elongate section and a first end secured at the open end of the grip tube chamber, the first end comprising an L-shaped member comprising a contact surface facing the open end of the grip tube chamber and extending circumferentially, the L-shaped member includes a vertical leg extending axially away from the contact surface at a first end forming a second conductive member end stop and a protuberance on the contact surface near a second end of the L-shaped member opposite the first end; wherein during attachment of the battery cover to the grip tube, the first conductive component contact surface interfaces with the second conductive component contact surface wherein the kinked portion of the first conductive component contact surface interferes with the second conductive component contact surface deflecting the first conductive component axially as the kinked portion slides circumferentially along the contact surface of the second conductive component creating an audible click as the kinked portion slides over the protuberance and contacting the first conductive component end stop with the second conductive component end stop subsequent to the audible click.

17 . The razor of claim 16 wherein the first conductive component comprises a spring holder, wherein the second leg of the U-shaped portion includes a battery spring biasing one or more batteries within the battery cover cavity and the grip tube chamber into contact with an electrical contact at an end of the grip tube chamber opposite the grip tube chamber open end.
