In order from the preformed member of Figure 23 and 24, to form flashlight, one user separates with bottom 352 top 350 of foam card with preformed member, then, the user folds into a vertical orientation with

end

300 and 302, then, folded edge 354,355 is so that contact pin 304 and 306 is by hole 404 and 406.Then, folded edge 356,357 and 358 is so that contact pin 304 and 306 location are by hole 404 and 406.At last, peel off back sheet 160, disclose double-sided belt, then, wall 358 is bonded to the upper surface of wall 354.Adopt this structure, construct 76 to 88 and do to strengthen or the sides 354,357 and 358 of Zhi Chengping, thereby provide synthetic flashlight, its look and feel as flashlight.

Being shown in Figure 26 and 27 is that the another kind of reflector assembly 10 improves, and wherein, side protective cover 48 comprises the chock plug 49 that extends from its lower surface, and the rear portion of sheet 14 comprises hole 51 by therebetween down.Reflector holding plate 142 comprises two leg extensions 143, and they have the hole 145 of the receivability chock plug 49 by therebetween.Like this, the rear portion of reflector 10 remains on down the rear portion of sheet 14 regularly, prevents any relative motion.

Be shown among Figure 28 is a flashlight 600 on being formed at the bottom of the cardboard.Yet different with the preformed member of flashlight among the former figure, flashlight 600 is formed on the foam card 140 simply.For operator torch 600, can be by isolating the bottom 143 of flashlight 600 from foam card 140, and remove contact pin 200, with this, flashlight 600 can take off from card simply.In this pattern, construct 76,78,80,82,84,86 and 88 and make fingerhold structure 303, push away the switch that flap 30 is actuatable flashlight 600 to allow the operator with its thumb.In this embodiment, structure 76 to 88 in use will be outstanding along roughly downward direction.

Another embodiment of the flashlight of user's assembling is disclosed among Figure 30 to 39, wherein, Figure 30 to 32 relates to a reflector assembly 500 of revising, and Figure 33 to 36 relates to the foam card 550 of modification, and Figure 37 to 39 relates to the stereogram of decomposition of the sheet material body 600 of all parts and modification.These will be explained in detail hereinafter.

Being shown among Figure 30 to 32 is a reflector assembly 500, and it is similar to reflector assembly 10, and identical part is represented with identical label.

Reflector assembly 500 is with reflector assembly 10 differences, has several improved features.

Lens subassembly 500 has the protective cover 48 on top flat 12; it (only illustrates one of them among Figure 31 by means of all clips or barb 502; another is on the inner surface of the protective cover of opposite side) be fixed in the egative film 14, described barb is clipped in down in the depression 504 on the bottom side of sheet 14.And in the leg 16 of four barbs of reflector assembly 10 one still remains in the reflector assembly 500, that is, and and the leg 16 of that barb of the most close lens 20.By fixing between sheet 14 and the top flat 12 under the interval, to compare with reflector assembly 10, lens subassembly 500 will have the rigidity of big level.

What extend along direction backward from the back of top flat 12 is a hook 506.This hook 506 will be by a hole 552 (seeing Figure 33), it be positioned at top castle shape leg on the foam card 550 on preceding surface.Hook 506 will help to prevent separating of reflector assembly 500 and foam card 550.If requirement, can comprise one with the barb of hook 506 shoulder at interval, with the groove that provides a hole 552 to locate therein, this groove will prevent top flat 12 towards or deviate from the motion of foam card 550.Do not have such shoulder, hook 506 only prevents that top flat 12 from deviating from the motion of foam card 550.

Upwardly extending from top flat 12 is a wedge shape area supported 508, it have with foam card 550 on the similar outward appearance of castellated leg.508 pairs of sheet material bodies around

reflector assembly

500 and 550 formation of foam card of supporting member provide additional supporting.

Lens subassembly 500 comprises edge 510, a location, and it forms an apron 512 on top flat 12, is forming apron 514 on the sheet 14 down.As can be seen from Fig. 32, apron 514 is taperings, that is, than in the zone 518 at place, the bottom of apron 514, apron 514 moves apart the bigger distance of lens 20 1 in the zone 516 at the connecting line place of sheet 14 down.

On the contrary, the width that remains unchanged basically of the edge that forms by apron 512.

The characteristic of the tapering of the apron 514 in the end half at edge 510 one is: when the front 602 of flashlight sheet material body 600 (seeing Figure 37) when being folded into reflector assembly 500, the circular port 604 by therebetween can be positioned on the edge 510 more easily.

If requirement, 510 the peripheral region at the edge can be provided with continuous or discontinuous bead perpendicular to edge 510, and hole 604 will be by wherein.One or more like this beads will help front 602 is remained on the certain position at edge 510.

Another serious difference between reflector assembly 10 and the reflector assembly 500 is that reflector assembly 500 has a back plate 520 that extends downwards.This back plate will be clipped between two parts of contact.Contact 522 substitutes the contact 150 of Figure 22.Contact 522 has the front portion 524 of the positive terminal of a joint lamp or bulb 24.In case contact 522 is positioned on the plate 520, the assembling reflector assembly 500 can be positioned on foam card 550 near, the foam card will keep battery, and the bottom that makes contact 522 and face 526 contact with the positive terminal of hithermost battery in foam card 550.

As shown in figure 30, the terminal of protective cover 48 comprises an elongated rib 530.This rib 530 will thus, by sheet material body 600, be welded to (as shown in figure 38) on the backer board 700 to allow rib 530 and chock plug 42 by the otch 606,608 and 610 of Figure 37 together with chock plug 42.

Backer board 700 is inverted U-shaped, and wherein, the leg 702 of U-shaped will engage and be welded on the rib 530, and elongate rib 542 will engage and be welded on the core 704 of backer board 700.U-shaped curve 703 on plate 700 provides a stopper or locator, so that accurately locate the palm side of thumb or finger, with open (ON) of actuation switch.

The chock plug 42 of reflector assembly 10 is substituted by the elongate rib 542 by hole 606, and therefore also is welded on the backer board 700.By ultrasonic welding process rib 530 and rib 542 are welded on the backer board 700, reflector assembly 500 is installed on the sheet material body 600 at the position at three intervals, therefore, provides the sub-assembly of a relative stiffness.

Sheet material body 600 is that with the difference of previous described embodiment the width of central plate 615 is different from the width of other plate 616,617,618 and 619.That is, body forms an irregular pentagon, and previous embodiment forms the pentagon of a rule.By the plate 615 that has big width is provided, the flashlight that assembles becomes such situation: to be shelved on the plane surface be in all limits 616,617,618 or 619 any one if be placed to, then being positioned at the battery of plate 615 vicinities and the weight of other parts will force flashlight to rotate, so that plate 615 is positioned at the bottom, thus, battery and other parts are in the equilbrium position.By the contact pin on rounding end face 602 and 300 304 and 306, also help the ability of this rotation or seeking balance position.

Because contact pin 304 and 306 keeps some elasticity or elastic force is arranged because of the amount of deflection behind the sheet bending, so, these contact pin 304 and 306 also help to keep flashlight to be in nonequilibrium position, unless the plate 615 that flashlight is placed in first example is positioned on the flat surface.

By flashlight in a single day look for the position of balance, plate 615 is positioned on the bottom, do not pay attention to opening (ON) and can not taking place of actuation switch.

Previous embodiment utilizes two-sided bringing that plate 619 is connected on the plate 617, yet, advantageously, providing a series of contact pin 620 along the outward flange of plate 619, it can be by being formed in the groove 622 between plate 617 and the outer flap 624.

The foam card 550 of Figure 33 to 36 is similar to the foam card 70 of Figure 17 to 19, and identical part will be represented with identical label.

Main difference comprises: the foamed material and the parts of wall 98 front portions are removed, make foam card 550 more simple.Therefore, by means of reflector assembly 500, foam card 550 is not staking out and props up sheet material body 600 that it just directly is fixed on the sheet material body 600.
