Description

P/00/01 1 Regulabon 3.2 AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION INNOVATION PATENT Invention Title: Folder device with a power supply The following statement is a full description of this invention, including the best method of performing it known to me: FOLDER DEVICE WITH A POWER SUPPLY The invention relates to a folder device, more particularly to a folder device with a power supply mounted on a spine thereof. 5 In commercial venues, such as restaurants, cafes, etc., information sheets, suchasmenus, orderingsheets, bills, etc., are usually clamped on a folder for positioning purposes and for providing conveniences to customers to read/look at the contents of the information 10 sheets, or to sign or write thereon. However, in some restaurants or cafes, because dim light is arranged in the premises in order to produce a romantic atmosphere, it is difficult for a customer to clearly see a menu or bill held by a folder handed by a waiter or to sign 15 or write thereon. An object of this invention is to provide a folder device incorporating a power supply for a light source. Accordingly, a folder device with a power supply according to this invention comprises: a folder body 20 having two panels, a spine interconnecting the panels, and an inner side defined by the panels and the spine; and a battery case having a base casing, a cover, and a battery chamber confined by the base casing and the cover. The base casing is fixed to the spine. The cover 25 is connected detachably to the base casing. Other features and advantages of the present invention will become apparent in the following detailed 2 description of the preferred embodiment with reference to the accompanying drawings, of which: Figure 1 is an exploded perspective view of the first preferred embodiment of a folder device according to 5 the present invention; Figure 2 is a sectional view of the first preferred embodiment; Figure 3isasectionalviewtakenalongline III III; Figure 4 is a sectional view taken along line IV-IV; 10 Figure 5 is an exploded perspective view of the second preferred embodiment of a folder device according to the present invention; and Figure 6 is a sectional view of the second preferred embodiment. 15 Before the present invention is described in greater detail with reference to the accompanying preferred embodiment, it should be noted herein that like elements are. denoted by the same reference numerals throughout the disclosure. 20 Referring to Figures 1 and 2, the first preferred embodiment of a folder device of this invention is shown to include a folder body 10, a battery case 20 and a battery unit 30. The folder body 10 has first and second panels 11, 25 12 that are movable between an opening position and a closing position, a pine 13 interconnecting the first and second panels 11, 12. The spine 13 has an outer face 3 131 and a plurality of nuts 132 embedded therein. The battery case 20 has a base casing 21, a cover 22, a plurality of screws 23 and a battery chamber 24 confined by the base casing 21 and the cover 22. 5 The base casing 21 has a first portion 25, a second portion 26, and two slide grooves 213 formed respectively in two opposite sides of the base casing 21 and extending from the first portion 25 to the second portion 26. The first portion 25 has a substantially 10 U-shaped cross section, and includes a bottom wall 251, a pair of lateral walls 252 extended from two opposite sidesof thebottomwall251, andanendwall253connected to one end of the bottom wall 251 and one end of each lateral wall 252. The bottom wall 251 is formed with 15 a plurality of through holes 254 that are respectively aligned with the nuts 132. A pole 211 is disposed on the end wall 253, and another pole 212 is disposed on another end wall of the second portion 26, which is opposite to the end wall 253. A plurality of screws 20 23 extend through the respective through holes 254 into the respective nuts 132, thus mounting fixedly the base casing 21 to the outer face 131 of the spine 13. The cover 22 is connected detachably to the base casing 21, and includes a stationary portion 27 covering 25 the first portion 25, and a movable portion 28 covering the second portion 26. Referring again to Figure 3, the stationary portion 27 of the cover 22 has a substantially 4 U-shaped cross section, two opposite slide 271 respectively engaging the opposite sides of the base casing 21, and two slide hooks 272 respectively provided on the opposite sides 271 to engage the respective slide 5 grooves 213 of the first portion 25. Referring to Figure 4, the movable portion 28 of the cover 22 has a substantially U-shaped cross section, a top wall 281, two opposite sidewalls 282 connected to the top wall 281, two slide rails 283 formed respectively on the 10 sidewalls 282, and an end plate 284 connected transversely to the top wall 281 and the two sidewalls 282. The two slide rails 283 engage slidably the respective slide grooves 213 of the second portion 26. The end plate 284 is opposite to the end wall 253 of 15 the base casing 21 and is used to close an open end of the battery chamber 24. The battery unit 30 includes multiple batteries 31 mounted in the battery chamber 24 of the battery case 20 for electrical connection with the poles 211, 212. 20 Referring back to Figures 2, 3 and 4, the stationary portion 27 is positioned to the first portion 25 of the base casing 21 through an engagement of the slide grooves 213 with the slide hooks 272. When the movable portion 28 is dctachcd from tho occond portion 26 of tho banc 25 casing 21, the battery chamber 24 is opened at one side distal from the end wall 253 of the base casing 21 to fill the batteries 31. To close the battery chamber 5 24, the battery chamber 24 may be attached to the base casing 21 by sliding the slide rails 283 of the movable portion 28 along the slide groove 213 to move the end plate 284 toward the battery unit 30. When the movable 5 portion 28 abuts against and is stoppedby the stationary portion 27, the batteries 31 are connected to the poles 211, 212. The power generated by the battery unit 30 can be supplied to a light-emitting element (not shown) for illuminating the folder device. 10 It is worth to mention that, the surfaces of the base casing 21 and the cover 22 may be provided with a coating layer 40 having the same color as the folder body 10 to hide the battery case 20. The coating layer 40 can also improve the aesthetic appearance of the folder 15 device. Referring to Figures 5 and 6, the second preferred embodiment of the folder device according to this invention is shown to include a folder body 10, a battery case 20' and a battery unit 30. The battery case 20? 20 has a base casing 21, a cover 22', a plurality of screws 23 and a battery chamber 24 confined by the base casing 21 and the cover 22'. The second preferred embodiment differs from the first preferred embodiment in that: The slide grooves 213 of the base casing 21 are 25 provided only in the first portion 25. The second portion 26 has a first side 261, and a second side 262 that is formed with a locking hole 263'. The movable 6 portion 28' of the cover 22' has a substantially U-shaped cross section, a connection end 281' connected pivotally to the first side 261, a free end 282' movable to the second side 262, and a locking piece 283' disposed on 5 the free end 282' and interlockable with the locking hole 263'. Preferably, the movable portion 28' and the second portion 26 of the base casing 21 are integrally formed as one piece. The second preferred embodiment is operable to pivot 10 the movable portion 28' relative to the base casing 21 for opening and closing operations so that the battery unit 30 can be conveniently removed and replaced.
