Benefits of technology

[0016] If a camming rib is mounted on the auxiliary base stand, the holder can be driven at least from the folded position towards the operative position automatically in response to movement of the auxiliary base stand from the second position towards the first position. In place of the camming rib, a geared transmission mechanism may be employed for transmitting movement of the auxiliary base stand between the first and second positions to the holder to thereby drive the holder between the folded and operative positions.

Problems solved by technology

Hence, the smaller the combination holder and battery charger is, the more unstable it is on a supporting surface, for example, a desk top or a shelf when the home appliance is placed thereon.
These attempts, however, is in contradiction to downsizing.
Another problem arising from downsizing of the combination holder and battery charger is found in difficulty in snugly and neatly accommodating an electric wire which extends outwardly from a charger unit built in the combination holder and battery charger for electric connection with a domestic power outlet.
Unless care is taken, the plug pins or blades may give rise to damage to the surface finish of a housing of either the electric appliance or the combination holder and battery charger.
The combination holder and battery charger of a type utilizing the plate fixture requires a mounting structure exposed to the outside of the housing for accommodating the plate fixture and, therefore, lacks a pleasing appearance.
By way of example, where the plate fixture prior to being secured to the wall surface is fitted to the housing of the combination holder and battery charger by the use of slide grooves formed in the housing and cooperating slide rails formed in the plate fixture, the slide rails tend to be exposed to the outside of the housing, resulting in degradation of the aesthetic appearance.
Also, when the electric appliance is placed on and held by the combination holder and battery charger, the electric appliances imposes a load on the embracing frame and, therefore, the holder tends to be slid downwardly, failing to hold the electric appliance stably.

first embodiment (figs.1 to 3)

[0056] First Embodiment (FIGS. 1 to 3)

[0057] Referring first to FIGS. 1 to 3, there is shown the combination holder and battery charger according to a first embodiment of the present invention. The illustrated combination holder and battery charger includes a generally rectangular box-like housing 2 accommodating fixedly an electric charger unit 23 therein and a holder 1 carried by the housing 2 for movement between folded and operative positions as will be described later. The housing 2 includes a generally rectangular top wall 2a, front and rear walls 2b and 2c and a pair of side walls 2d, all of which may be assembled of one-piece construction by the use of a plastics molding technique so as to open downwardly. The housing 2 also includes a bottom plate 3 used to close the bottom opening of the housing 2 with the charger unit 23 encased therein.

second embodiment (fig.4)

[0072] Second Embodiment (FIG. 4)

[0073] In an embodiment shown in FIG. 4, the housing 2 has its bottom formed with a bottom plate chamber 26 in the form of a cavity opening downwardly of the housing 2 and also laterally outwardly in a direction perpendicular to the longitudinal sense of the bottom of the housing 2, and the bearing boss 31 is formed at a geometric center of the shape of the bottom plate chamber 26 so as to protrude downwardly. One of opposite sides of the bottom plate chamber 26 is formed so as to communicate with a lower end of the slide space 21. The load support 27 in the embodiment shown in FIG. 4 for supporting the housing 2 is defined at the bottom of the housing 2 at a location adjacent each of the opposite side walls 2d so as to protrude downwardly from a level flush with an upper bottom surface of the bottom plate chamber 26, and has an inner face inwardly recessed to define a rounded inner face having the center of curvature lying in alignment with a longit...

third embodiment (figs.5 to 8a)

[0076] Third Embodiment (FIGS. 5 to 8A)

[0077] In an embodiment shown in FIGS. 5 to 8B, and referring particularly to FIG. 5, the top wall 2a of the housing 2 is partly stepped down to define a storage space 22 of a size sufficient to accommodate the apertured holder plate 11 therein. Specifically, when the holder 1 is in the folded position, the apertured holder plate 11 is nested within the storage space 22 with its top surface held in flush with a top surface of the top wall 2a of the housing 2. Also, as shown in FIG. 6, the bottom plate 3 in this embodiment is formed integrally with the housing 2.

[0078] The combination holder and battery charger may additionally include a linkage means is provided for drivingly linking the holder 1 and the base plate 4 together such that as the base plate 4 is turned about the bearing boss 31 the holder 1 can be moved with the slide plate 12 guided by the slide grooves 7. In the embodiment shown in FIGS. 5 to 8B, the linkage means includes a camm...

Abstract

A combination holder and battery charger for holding a battery operated electric appliance and also for recharging the battery in the electric appliance includes a housing having top and bottom surfaces opposite to each other. An auxiliary base stand is operatively disposed on the bottom surface of the housing and capable of assuming one of first and second states. This auxiliary base stand when in the first position has at least a portion thereof protruding laterally outwardly from a contour of the bottom surface of the housing, but that portion of the auxiliary base stand to enable the combination holder and battery charger to be supported stably on a support surface. The combination holder and battery charger may include a wall attachment for securement of the combination charger and holder to a wall surface.

Description

[0001] 1. Field of the Invention[0002] The present invention generally relates to a combination holder and battery charger for a battery operated home appliance such as, for example, a rechargeable electric shaver, a rechargeable hair curler, a rechargeable toothbrush and a battery operated skin cleaner of a kind that requires, or is combined with, a combination holder and battery charger.[0003] 2. Description of the Prior Art[0004] The battery operated home appliances of a kind referred to above includes at least one built-in storage battery that requires an occasional charging to electrically recharge it. A battery charger for reenergize the built-in storage battery available either in combination therewith or as an optional item is designed to concurrently serves as a holder for supporting or holding the elongated home appliance while the latter is not in use and / or being recharged.[0005] In recent years, some of the battery operated home appliances are being manufactured with th...
