Detailed Description

FIG. 1 shows a schematic view of a

In fig. 1, a device is shown configured as a garment 101 having an outer layer comprising an outer surface 102 having high visibility characteristics. A plurality of light emitting devices may be connected to the control unit via a wire connection, and each of these devices is fixed to the outer layer 102. In the embodiment shown in fig. 1, a first LED group 111 and a second LED group 112 are shown. In this embodiment, each of the light emitting device groups is disposed on a circuit board, and the circuit board is fixed on the inner surface of the outer layer. The light emitting devices pass through corresponding holes in the outer layer and each group is held within a molded rubber strip attached to the outer surface 102.

The outer layer is made of a fluorescent material to which a reflective tape 113 is fixed. In one embodiment, the retroreflective tape is secured by edge stitches 114 and portions of the wireties are constrained under the retroreflective tape 113 between the edge stitches 114. Further, as shown in fig. 1, the light emitting device may be located on an outer layer including the light reflecting band 113. In the embodiment of fig. 1, the rear of the garment is provided with a similar set of LEDs.

The main zipper 115 is shown in a closed position in use in figure 1.

FIG. 2

In fig. 2, the garment 101 is shown with the zipper 115 in an open position for easy removal of the garment. The pocket zipper 201 is in a closed state.

FIG. 3

The pocket zipper 201 can be conveniently opened with the main zipper 115 in an opened state, in which the pocket is in an opened state in fig. 3. The pocket can be opened when the main zipper is in the closed position, but use of the pocket during work in hazardous conditions is not recommended. Thus, necessary articles are inserted at the time of starting to use the clothes, and then the articles can be removed while taking off the clothes. Thus, the position of the pocket zipper is deliberately close to the position of the main zipper to avoid using the pocket during use.

The pocket itself is defined by an outer pocket layer 301 and an inner pocket layer 302. In addition, a cavity in the outer pocket layer 302 allows the exposed wire connector portion 303 to be received in a pocket to preset a connection to the control unit at the start of a shift.

FIG. 4

At the start of the shift, the operator puts on clothes as shown in fig. 4. In this state, the pocket zipper 201 is open, providing access to the exposed connector portion 303. The charging control unit 401 is connected to the exposed connector portion 303, and then the control unit 401 is held in a pocket. The pocket zipper 201 is then closed to provide a condition similar to that shown in figure 2, and the main zipper is then closed to provide a condition substantially similar to that shown in figure 1.

FIG. 5

In fig. 5, the garment 101 is shown with the main zipper in an open state. In addition, the pocket zipper 201 is also in an open state. Further, a lining zipper 501 is provided to provide a passage between the outer and inner layers 502 when in an open condition as shown in fig. 5.

The opening of the lining zipper as shown in fig. 5 is not normal operation when the garment is worn, and the lining zipper and the pocket zipper shown in fig. 5 are both open for illustrative purposes only. In use, the operator is not advised to use the lining zipper 501. In this embodiment, the liner zipper 501 is purposefully obscured by the pocket zipper 201. Thus, the entire assembly is designed so that under normal use conditions, the lining zipper is less likely to be known to the operator. However, the lining zipper can provide easy access to the active element LED groups when maintenance and service procedures are required.

FIG. 6

A zipper such as a lining zipper 501 is shown in fig. 6. The zipper comprises a stringer 601 defined by two halves of the zipper engaged together. The size of the chain 601 is defined by a chain gauge 602. In the art, the gauge dimensions are indicated by numbers, with larger numbers indicating wider chain widths. In one embodiment, the pocket zipper 201 has a first chain gauge and the liner zipper 501 has a second chain gauge, wherein the first chain gauge for the pocket zipper is larger than the second chain gauge for the liner zipper. In one embodiment, the chain gauge of the main zipper 115 is similar to the chain gauge of the pocket zipper 201.

The zipper in fig. 6 includes a slider 603 that moves up and down the chain to open or close the zipper. For the liner zipper 501 shown in FIG. 6, raising the slider 603 will open the zipper, and similar operations on the pocket zipper 201 and main zipper 115 will cause these zippers to close. A pull tab 604 extends from the slider 603 to assist in the manual movement of the slider 603. In this embodiment, the pull tab for the liner zipper 501 is smaller than the similar pull tabs for the pocket zipper 201 and the main zipper 115.

The zipper includes a first tape 611 and a second tape 612. Each band having a single bandwidth 613. The movement of the slide 603 is limited between a top stop 614 and a bottom stop 615. The zipper used is substantially as described in US 2065250.

FIG. 7

Fig. 7 schematically shows a cross section of an embodiment with a main zipper chain 701, a pocket zipper chain 702, and a lining zipper chain 703, all in a closed state.

An outer layer 704 is shown having a high visibility outer surface 102 and an inner surface 705 as previously described. Inner layer 502 includes a hidden surface 706 and an exposed surface 707. The outer pocket layer 301 and the outer pocket layer 302 define a pocket 708 for receiving the control unit 401, which in turn may be connected to a connector.

To provide access to the devices held between the inner surface of the outer layer and the hidden surface of the inner layer during service and maintenance, a lining zipper is provided. However, the use of a lining zipper is not recommended during use, and the present embodiment provides a structure that facilitates the effective concealment of the lining zipper behind the pocket zipper. Further, by placing both the liner zipper and the pocket zipper in a position adjacent to the main zipper, manipulation of the liner zipper and the pocket zipper during use is avoided. Thus, when the main zipper is closed and access to the pocket zipper is difficult, the liner zipper is inaccessible. However, as described in the description of fig. 4, the pocket zipper is easily accessible when the main zipper is in an open state. To this end, a first stitch 711 secures the first pocket fastener tape 721 to the inner pocket layer 302, the first main fastener tape 731, and the first liner fastener tape 741.

In one embodiment, second stitches 712 secure outer layer 704 to second pocket fastener strip 742 and outer pocket layer 301 to provide access to pocket 708.

Further, in one embodiment, third stitches 713 secure the inner layer 502 to the second liner fastener strip 742 to provide access to the area between the inner layer 502 and the outer layer 704.

FIG. 8

Fig. 8 shows another wearable device as a garment, which is also used to enhance visibility of the operator in a hazardous environment. The garment has an outer layer with an outer surface 801 having high visibility characteristics, and an inner surface substantially in contact with the hidden surface of the inner layer, which also has an exposed surface for contact with an operator when worn.

Also, a plurality of light emitting devices may be connected to the control unit via the wire connector. However, in the embodiment of fig. 8, the outer layer includes a plurality of windows including a first window 811, a second window 812, and a third window 813, and the respective LED devices are located behind the windows. The light emitting device group is disposed on the circuit board, and a transparent material placed over the window is fixed on the inner surface.

In one embodiment, the transparent material includes a first extension portion extending over the circuit board and a second extension portion extending over the first extension portion. The advantage of the structure shown in fig. 8 over the structure shown in fig. 1 is that the LED device is not exposed and protected by a transparent material. However, this makes it more difficult to contact the damaged LED device, and thus the effect of the lining zipper is enhanced. In addition, the lining zipper also facilitates retrofitting of LED devices of the type shown in fig. 8.

FIG. 9

In one embodiment, a flexible printed circuit board provides a substrate for supporting a first light emitting device. In this embodiment, the second light emitting device and the third light emitting device are also supported by the flexible printed circuit board.

A first set of contacts is provided for connection to an input side of the wire connector and a second set of contacts is provided for connection to an output side of the wire connector. The contacts are pre-tinned to assist in soldering of the wire connectors.

The connector is assembled using a ribbon cable to be connected with the flexible printed circuit board. The first ribbon cable section has conductors soldered to the first set of contacts and the second ribbon cable section has conductors soldered to the second set of contacts.

A heat-shrinkable lining (hot-line heat-shrink) is applied to the soldered connection of the first ribbon cable section. Similarly, a heat shrink liner is applied to the solder connection of the second ribbon cable section.

A group of three LED devices on a substrate of a flexible printed circuit board may be considered as an LED strip. To form a connector, a plurality of LED strips are connected by cables, and in one embodiment, four strips are connected in this manner. Each strip may comprise three light emitting devices, but it will be appreciated that other configurations of devices are possible.

In some wire connectors, the device may emit a single color of light in response to activation by the control unit. However, in another embodiment, different colored devices may be included in each strip. Further, in another embodiment, a single device may produce multiple colors, and color selection is effected in response to a data cable included in the hub receiving control data. Thus, the cables within the hub typically include power cables and data cables. Further, in addition to transmitting data to the various devices, the data cable may also be configured to receive data from a detection device connected to the hub.

After the application of the heat shrink liner, a transparent silicone protective coating may be applied, which is suitable for operation at temperatures in the range of-65 ℃ to 200 ℃. In one embodiment, the silicone coating has a thickness of 200 microns, thereby preventing excessive bending of the flexible printed circuit board to ensure that the shoulder features remain in place.

FIG. 9

After the barrier film is fixed to the inner surface, the template 901 is placed on the second protective film. Template 901 includes a first hole 911, a second hole 912, and a third hole 913. The spacing between the holes is adapted to the spacing between the individual LED devices within the LED group. Thus, the holes 911-913 define the locations of the windows for the LED devices.

FIG. 10 shows a schematic view of a

After the template 901 has been applied, a twist cutting operation (twist cutting operation) is performed by a drill 1001 at the location of each of the holes 911-913, as described in the description of fig. 9. The twist cutting operation is used to form clean cut holes in the second protective film, the upper adhesive layer, the barrier film, the adhesive outer layer, and the light reflecting tape.

FIG. 11

After three holes are twist cut through the adhesive film, the second protective film is removed so that the adhesive film presents an unprotected upper adhesive layer for receiving the transparent plastic material.

FIG. 12

The transparent plastic material 1201 includes a central portion 1202, a first flap 1203 and a second flap 1204.

To define the respective windows, a central portion 1202 of the transparent plastic material 1201 is positioned over a first hole 911, a second hole 912 and a third hole 913, which include a first window 1211, a second window 1212 and a third window 1213.

FIG. 13

In one embodiment, the gasket 1301 (possibly composed of a foam-based material) is secured by an upper adhesive layer. Shim 1301 includes first shim hole 1311, second shim hole 1312, and third shim hole 1313. The gasket holes 1311-1313 are aligned with the respective windows 1211-1213.

FIG. 14

The LED bar is positioned above the pad 1301. The first, second, and third pad holes 1311, 1312, and 1313 are provided to be interference-fitted with the first, second, and third light emitting devices 111, 112, and 113, respectively.

Thus, light emitting devices 111-113 are held within respective gasket holes 1311-1313 by applying pressure in the direction of second arrow 1401.

FIG. 15 shows a schematic view of a

In one embodiment, a protective layer 1501 is provided over the LED strip after the light emitting devices are received in the holes on the spacer 1301, as described in the description of fig. 14.

The first flap 1203 is folded on the rear surface of the substrate (flexible printed circuit board), in this embodiment, so that the first flap 1203 is in contact with the protective layer 1401. Thereafter, the second flap 1204 is further folded over the substrate-folded first flap 1203. Furthermore, by connecting the further folded second flap to the folded first flap, the whole assembly is made safe and waterproof.

FIG. 16

Fig. 16 shows a cross section from XVI to XVI. A respective window 1213 is provided for each light emitting device. The holes through the reflective tape are covered by a transparent plastic material 1201 which defines a first flap 1203 and a second flap 1204.

The first flap 1203 is folded around the base panel and then the base panel is secured by the second flap 1204 by further folding the second flap over the first flap 1203. The transparent plastic material 1201 is secured to the inner surface of the outer layer by an adhesive film cut out of the hole.

In this embodiment, the substrate is a flexible printed circuit board. The adhesive film comprises a central barrier layer to which the light reflecting tape is adhered by a first adhesive layer and to which the transparent plastic material 1201 is adhered by an upper adhesive layer.

In this embodiment, the pad 1301 surrounds the light emitting device. This embodiment also includes a protective layer 1501 and an adhesive film 1601 is disposed between the first flap 1203 and the second flap 1204 to fully secure the second flap 1204 to the folded first flap 1203.
