Patent Application
20050007066
This invention relates to charging stands, and more particularly, to charging stands having a cover that can be closed for storage of a rechargeable appliance such as a hair trimmer, beard trimmer or the like, or opened and set on a table with the appliance in a raised position.
Charging stands have been used for storing rechargeable hair trimmers and other appliances and charging their internal batteries. The charging stand typically has a base and a cradle. The stand supports the hair trimmer in an inclined position. Power is provided through contacts in the charging stand, which in turn receives power through a power cord that is routed under or behind the base of the charging stand.
When traveling, the stand must be taken to charge the clipper, but the stand is bulky and awkward to pack, and the clipper is typically packed separately, usually uncovered. Thus, there is a need for compact charging stands that can be conveniently packed in luggage. There is also a need for storage devices for appliances such as hair trimmers and other rechargeable personal care items.
In keeping with one aspect of the invention, a charging stand for selectively enclosing and exposing an appliance such as a hair trimmer having a rechargeable battery includes a base and a cover. The base has an access opening for supporting the appliance, and electrical contacts for charging the battery. The cover fits over the base to define an interior space for enclosing the appliance, and can be secured to the base in at least two positions. In a first position, the cover encloses the appliance with the base. In the second position, the cover exposes the appliance when the appliance is in a raised position.

The rechargeable unit 12 includes a housing 16 with a working end 18 which, as illustrated, is equipped with a bladeset 20. On the opposite end of the housing 16 from the working end 18 is a charging end 22. The charging end 22 may have a pair of contacts (not shown) for charging an internal rechargeable battery or batteries.
The charging stand 10 includes a cover 26 for supporting the base 14 upon a substrate such as a table, countertop or shelf when the charging stand is in a fully open position, as in
The base 14 has essentially the same configuration as the cover 26, so that the cover fits on the base when the cover 26 is closed to form a case. The base 14 and cover 26 may be plastic or any other suitable material, and may be opaque, or clear for viewing the rechargeable unit 12 through the storage unit 10.

A panel 42 is also disposed on the rounded top region 30 of the front piece 33 above the top wall 36 and extends along two sides of the base interior space 43, outwardly disposed from the side walls 38. The rear piece 35 has an edge 44 adjacent to the side panel 42, and a lateral detent (not shown) which is continuous around the side panel. The side panel 42 fits inside the edge 44.
The base 14 defines a docking recess 47 for receiving the rechargeable appliance 12. The front of the recess 47 is formed by the front piece 33, and the back of the recess 47 is formed by the rear piece 35. The front of the recess 47 may have a graphics area 31 for brand identification or other indicia.

Typically, there are two contacts on each of the rechargeable unit 12 (contacts not shown) and the base 14 which are located in adjacent relationship to each other. While the preferred embodiment has two contacts 56, it is contemplated that the number and positioning of the contacts may vary to suit the application, such as a personal digital assistant or other digital device, provided there is at least one contact 56 constructed and arranged for making physical and electrical contact with a contact on the rechargeable unit 12. Recharging is achieved by the electrical connection between the rechargeable unit 12 contacts and the base 14 contacts, and the connection is typically maintained through the physical engagement of the corresponding metallic contacts on both the unit and the base.
The contacts 56 may be configured for causing an enhanced, more consistent wiping contact action between the contacts on the rechargeable unit 12 and the contacts 56 on the base 14. In the preferred embodiment, the wiping engagement is created by the contacts 56 forming an inclined surface above the floor 52, defining an inverted “U” shape. It is also contemplated that the contacts 56 need not project through the floor 52, but may be flush or recessed, depending on the configuration of the contacts on the rechargeable unit 12.
Also included in the docking recess 47 is a curved wall 58 which follows the curvature of the housing 16 of the rechargeable unit 12. The docking recess 47 forms a receptacle for the charging end 22 and the curved wall 58 extends upwardly a length suitable to maintain the rechargeable unit 12 in the recess. Extending over the outer periphery of the curved wall 58 at each side of the docking recess 47 is the side panel 42. The side panel 42 is molded to the front part that forms the recess 47, to form the front piece 33. Ends 60 of side walls 38 are angled such that the edge portions 62 of the side walls are further from the top region 30 than the back-side portion 63 (best seen in
For inserting and removing the rechargeable unit 12, an access opening 68 is defined by the curved wall 58 and walls 36, 38 and 40 of the base 14. During insertion of the rechargeable unit 12 into the base 14, as illustrated in

A rounded side 82 and an angled side 84 are located on either side of the bottom 70, the angled side having a generally oval shape and forming a generally 45-degree angle with the bottom. Located above the angled side 84 on the rear piece 35 of the base 14 is an inclined recess 86 for the socket 76. The recess 86 has a bottom 88 inclined perpendicular to the direction of inclination of the recess. Centrally disposed on the recess bottom 88 is the socket 76, configured to receive the male end of the cord 80 when the charging stand. 10 is in an open position, or when the socket 74 is otherwise inaccessible (best seen in
Above the inclined recess 86 is an elongated groove 94 which generally forms a “V” in profile. Two opposing groove sides 96 are disposed laterally across the rear piece 35 of the base 14. Due to the generally rounded shape of the base 14, the depth of the groove 94 from the surface of the rear piece 35 is greatest at the center and tapers towards the sides of the groove. Located on one of the groove sides 96 are two protrusions 97. The groove 94 and the protrusions 97 are configured to engage the cover 26 when the charging stand 10 is in the fully open position.

Located at the lower end 100 of the cover 26 are two legs 110 longitudinally aligned with the upper end 98 of the cover 26. Two feet 112 are disposed at the end of legs 110 on both sides of a groove receiving edge 114 and are pivotably engaged with the base 14 at the bottom region 32. The feet 112 have a generally perpendicular alignment with the legs 110 (best seen in
As seen in
In order to convert the charging stand 10 to an open position, the cover 26 and the base 14 are first separated by releasing the latch 126. Once separated, the cover 26 is pivoted beneath the base 14 approximately 315 degrees until the groove receiving edge 114 of the cover 26 engages the groove 94. The base 14 is supported by the cover 26 at the groove receiving edge 114 and the access opening 68 of base 14 is exposed for inserting or removing the rechargeable unit 12.
In this fully open position, the base 14 and the cover 26 form approximately a 45-degree angle, although an upright position or any angle of inclination suitable for retaining the rechargeable unit 12 within the base 14 is contemplated. The angled side 84 of the bottom 70 is angled such that when the groove receiving edge 114 engages the groove 94, the angled side lays flat on the table or other substrate. Also contacting the table and supporting the base 14 are the feet 112, now normal to the substrate, and the top wall 102 of the cover 26. The central curve 124 of the cover 26, however, does not contact the table, as seen in
While particular embodiments of the charging stand have been shown and described, it will be appreciated by those skilled in the art that changes and modifications may be made thereto without departing from the invention in its broader aspects and as set forth in the following claims.
