Description

The present invention relates to a harness for workers, and more specifically to a harness worn by workers who perform work using portable information processing devices.

In recent years, the use of portable information processing devices such as smartphones and tablet computers has become increasingly common when inspecting structures such as highways, in order to improve work efficiency and share information. For example, Patent Document 1 discloses a work support system that supports inspection and maintenance work on facility equipment by allowing workers inspecting equipment at facilities such as roads, tunnels, bridges, buildings, and apartment buildings to input inspection results into a mobile device such as a smartphone, which then transfers the input inspection results to a center server for storage.

JP 2015-49828 A

However, when workers inspecting the roads, tunnels, bridges, etc. mentioned above use portable information processing devices such as tablet computers, they must handle them with care to prevent work from being stopped due to dropping or damage to the device. Furthermore, even when the portable information processing device is not in use, for example, while traveling to a work location or while working with tools or equipment, they must handle it with care to prevent work from being stopped due to dropping or hitting a structure or damage to the device.

In one aspect, the present invention aims to reduce the burden on workers involved in handling portable information processing devices.

Figure 3 is a side view illustrating an example of how to use the worker's garment according to one embodiment.

The worker wearable device 1 (hereinafter referred to as "wearable device 1") illustrated in Figures 1 and 2 is worn by a worker performing work using a portable information processing device 2 (hereinafter referred to as "tablet terminal 2"), such as a tablet computer. Examples of work using the tablet terminal 2 include inspection work on roads, tunnels, bridges, etc. The tablet terminal 2 is a general-purpose computer that has a touch panel display with a position detector (digitizer) as an input unit superimposed on the display surface, such as an LCD display, and a communication interface that enables wireless or wired communication with external devices. The tablet terminal 2 may also have a photographing function, such as a digital camera.

As illustrated in Figures 1 to 3, the wearing device 1 has a device holding section 100 on which a tablet device 2 is placed and held, and a protection section 120 connected to the device holding section 100. The device holding section 100 is configured to be able to place and hold a tablet device 2 with the touch panel display 200 of the tablet device 2 in an open state (in other words, a state in which the worker 3 can observe and operate the touch panel display 200) (see Figure 3). Furthermore, the device holding section 100 in the wearing device 1 of this embodiment is provided with an opening/closing section 110 that allows a digital camera mounted on the surface of the held tablet device 2 facing the device holding section 100 to be used while the tablet device 2 is held by the device holding section 100. The opening/closing section 110 and the surrounding configuration of the device holding section 100 will be described later with reference to Figure 5.

The device holding unit 100 is preferably configured to be able to place and hold multiple types of tablet terminals 2 with similar external dimensions, and is not limited to a specific model. Furthermore, the device holding unit 100 is preferably configured to be able to hold a tablet terminal 2 with a case 4 attached, as described below with reference to FIG. 4, for example. The case 4 may be a hard case that provides one or more functions for protecting the tablet terminal 2, such as shock resistance, dust resistance, and waterproofing. When the device holding unit 100 holds a tablet terminal 2 without a case 4 attached, it may have additional functions for protecting the tablet terminal 2.

The protective unit 120 is connected to the device holding unit 100 in such a manner that its relative position with respect to the device holding unit 100 can be changed between a position where it covers and protects the touch panel display 200 of the tablet terminal 2 held by the device holding unit 100, and a position where the worker 3 can observe and operate the touch panel display 200 of the tablet terminal 2. The configuration of the connection between the device holding unit 100 and the protective unit 120 is not limited to a specific configuration. For example, the device holding unit 100 and the protective unit 120 are connected by sewing together one side of a piece of cloth (fabric) used to make the device holding unit 100 and one side of another piece of cloth used to make the protective unit 120. Alternatively, the device holding unit 100 and the protective unit 120 may be connected by a single piece of cloth having a portion used as the material for the device holding unit 100 and a portion used as the material for the protective unit 120.

The relationship between the connecting portion of the device holding unit 100 with the protective unit 120 and the orientation of the tablet terminal 2 held by the device holding unit 100 is not limited to a specific relationship. For example, if the screen displayed on the touch panel display 200 when the worker 3 operates the tablet terminal 2 is a screen suitable for display in landscape orientation, one of the edges of the device holding unit 100 along the long side of the tablet terminal 2 on which the tablet terminal 2 is placed is connected to the protective unit 120.

The device holding unit 100 and the protective unit 120 can maintain the tablet device 2 held by the device holding unit 100 in a state protected by the protective unit 120 by fastening a flap 121, which is provided on the side (upper end) of the protective unit 120 opposite the connection part with the device holding unit 100, to the device holding unit 100. The method for fastening the flap 121 to the device holding unit 100 is not limited to a specific method. The flap 121 can be fastened to the device holding unit 100 by a fastener such as a hook-and-loop fastener or a snap button. Instead of the flap 121, a connector such as a side release buckle can be used to connect the belt on the device holding unit 100 side to the belt on the protective unit 120 side, thereby maintaining the touch panel display 200 of the tablet device 2 in a state protected by the protective unit 120.

When wearing the harness 1 of this embodiment, as shown in FIG. 3, the worker 3 wears it so that they can operate the tablet device 2 while wearing it. That is, the face of the protective part 120 opposite the face that faces the device holding part 100 (in other words, the face that faces and protects the touch panel display 200 of the tablet device 2) faces the front of the worker 3 (e.g., the chest or abdomen). For this reason, the protective part 120 is equipped with a belt part that positions the protective part 120 in front of the worker 3 when worn, with the connecting part with the device holding part 100 facing downward. The belt part of the harness 1 shown in FIGS. 1 to 3 includes a pair of shoulder straps 140, 145, a pair of waist straps 150, 155, and a cushion part 160.

The pair of shoulder straps 140, 145 are each belt-like components whose length can be adjusted using a tape adjuster (not shown) or the like. One end of each of the shoulder straps 140, 145 is attached to the side of the protective unit 120 opposite the side to which the device holding unit 100 is connected, and the other end is attached to the cushion unit 160. When wearing the wearing device 1, the shoulder strap 140 attached to the right end of the protective unit 120 is placed over the right shoulder of the worker 3, and the shoulder strap 145 attached to the left end of the protective unit 120 is placed over the left shoulder of the worker 3. By adjusting the length of the shoulder straps 140, 145, the vertical position (height) of the protective unit 120 in front of the worker 3 can be adjusted so that, for example, the worker 3 is positioned to easily operate the tablet terminal 2.

The pair of waist wrap sections 150, 155 are each belt-like components whose length can be adjusted using a tape adjuster or the like (not shown), and consist of two belts connected by a connector such as a side release buckle (not shown). Of the two connected belts of the waist wrap section 150, one end of one belt is attached to the lower side of the right side of the protection section 120 (close to the connection with the device holding section 100), and one end of the other belt is attached to the cushion section 160. Of the two connected belts of the waist wrap section 155, one end of one belt is attached to the lower side of the left side of the protection section 120 (close to the connection with the device holding section 100), and one end of the other belt is attached to the cushion section 160. When wearing the wearing device 1, for example, first, the connection between the two belts by the connectors of either or both of the waist wrap section 150 and waist wrap section 155 is released, and then each of the pair of shoulder strap sections 140, 145 is hung over the shoulder. Thereafter, the two belts, with either or both of the waist wrapping section 150 and the waist wrapping section 155 now disconnected, are connected. At this time, the length of the waist wrapping sections 150, 155 is adjusted to position the protective section 120 in the left-right direction, thereby adjusting the left-right position (height) of the protective section 120 in front of the worker 3. Furthermore, for example, by adjusting the length of the waist wrapping sections 150, 155 to match the waist size of the worker 3, the position of the protective section 120 in front of the worker 3 can be stabilized, preventing the protective section 120 and device holding section 100 from shaking when the worker 3 moves.

The cushion part 160, to which the pair of shoulder straps 140, 145 and the pair of waist straps 150, 155 are attached, distributes the load on the back of the worker 3 wearing the harness 1.

When the worker 3 wears the harness 1, as illustrated in FIG. 3 , the device holding unit 100 can be opened forward, using the connection between the device holding unit 100 and the protective unit 120, which is positioned in front of the worker 3, as a fulcrum. The opened-forward device holding unit 100 is supported at a predetermined angle (e.g., 80 to 90 degrees) relative to the protective unit 120 by a hanging band 130 having a first hanging unit 132 and a second hanging unit 134. For example, as viewed from the worker 3 wearing the harness 1, the left end of the device holding unit 100 is supported by the first hanging unit 132, and the right end is supported by the second hanging unit 134. Therefore, the worker 3 can, for example, view and operate the touch panel display 200 of the tablet terminal 2 held by the opened-forward device holding unit 100, even if the worker 3 does not hold the device holding unit 100 himself. Specific examples of how to attach the hanging band 130 will be described later with reference to Figures 4 to 6.

On the other hand, when the tablet device 2 is not in use, the device holding unit 100 is closed so that the touch panel display 200 of the tablet device 2 held by the device holding unit 100 faces the protective unit 120. For example, the flap 121 (see FIG. 1) provided at the top end of the protective unit 120 can be fastened to the device holding unit 100. The flap 121 and the device holding unit 100 can be fastened using a fastener such as a hook-and-loop fastener, allowing the device holding unit 100 to remain closed when the tablet device 2 is not in use. Furthermore, by adjusting the lengths of the pair of shoulder straps 140, 145 and the pair of waist straps 150, 155, the protective unit 120 can be positioned (placed) in front of the worker 3 to prevent misalignment during work. Therefore, the worker 3 wearing the harness 1 of this embodiment can carry the tablet device 2 without the tablet device 2 interfering with the worker 3's work when not in use. Furthermore, when the device holder 100 is closed, the touch panel display 200 of the tablet terminal 2 is protected by a protective section 120 located between the tablet terminal 2 and the front of the worker 3. This reduces the burden on the worker 3 regarding handling the tablet terminal 2 when the tablet terminal 2 is not in use.

Figure 4 is a perspective view illustrating an example configuration of a device holding section in a worker wearable device according to one embodiment. Figure 5 is a partially enlarged front view illustrating an example configuration of the opening/closing section of the device holding section and its surrounding area. Figure 5(a) illustrates the state of the device holding section 100 when the camera is not in use, and Figure 5(b) illustrates the state of the device holding section 100 when the camera is in use. Figure 6 is an exploded perspective view illustrating an example method of creating a device holding section.

As shown in FIG. 4, the surface 101 of the device holding section 100 of the wearing device 1 of this embodiment, which faces the protective section 120 when closed, is provided with a pair of holding members 102, 103 that hold the tablet terminal 2, and fastening members 104 to 107.

The pair of holding members 102, 103 extend along the upper and lower edges of the tablet terminal 2 placed on the surface 101 of the device holding unit 100 as viewed from the worker 3, and prevent the tablet terminal 2 from shifting in the front-to-back direction when in use (or the up-to-down direction when not in use) and from falling off (falling) from the device holding unit 100. As illustrated in FIG. 6 , each of the pair of holding members 102, 103 has a first portion attached (e.g., sewn) to the surface 101 of the device holding unit 100, a second portion extending from the first portion and facing the side of the tablet terminal 2, and a third portion extending from the second portion and facing the edge of the top surface of the tablet terminal 2 (the surface on which the touch panel display 200 is provided). The third portions of the holding members 102, 103 each have a portion extending along the left edge and a portion extending along the right edge of the tablet terminal 2 at the left and right ends as viewed from the worker 3 wearing the harness 1. The second portions of the holding members 102, 103 are designed to be easily deformed so that they can hold multiple types of tablet terminals 2 with different thicknesses. The third portions of the holding members 102, 103 are designed to be less prone to deformation, for example, by inserting a core material to prevent the tablet terminal 2 from falling off. The configuration and manufacturing method of the holding members 102, 103 are not limited to any specific configuration or manufacturing method. For example, the holding members 102, 103 may each be made using an elastic material that allows the cross-sectional shape of the transverse section (the cross-sectional shape in a plane including the front-to-back and up-to-down directions in Figure 3) to be deformed, as long as the function of holding the tablet terminal 2 is not impaired.

The fastening members 104 to 107 are flap-shaped members provided along the left and right edges of the tablet terminal 2 placed on the surface 101 of the device holding unit 100, as viewed from the worker 3. By fastening them to the holding member 102 or the holding member 103, they prevent the tablet terminal 2 placed on the surface 101 of the device holding unit 100 from shifting left and right. The method of fastening the holding member 102 to the fastening members 104 and 105, and the method of fastening the holding member 103 to the fastening members 106 and 107, are not limited to any particular method. The holding member 102 to the fastening members 104 and 105, and the holding member 103 to the fastening members 106 and 107, are fastened, for example, by hook-and-loop fasteners.

As described above, the device holding unit 100 in the wearing device 1 of this embodiment is provided with an opening/closing unit 110 that allows a digital camera provided on the surface 101 of the held tablet terminal 2 that faces the device holding unit 100 to be used while the tablet terminal 2 is held by the device holding unit 100. Here, with reference to Figure 5, an example of the configuration of the opening/closing unit 110 and its surroundings in the device holding unit 100 will be described.

Some tablet devices 2 held by the device holding portion 100 of the wearing device 1 of this embodiment have a camera 210 on the side opposite the side on which the touch panel display 200 is provided. When carrying this type of tablet device 2, for example, images of inspection locations taken by the tablet device 2's camera 210 can be recorded and stored together with the inspection results, and the images can be used for diagnosis, etc.

However, if the camera 210 of the tablet terminal 2 held by the device holding unit 100 is always exposed, there is a risk that the lens may become scratched or dirty during work, making it impossible to take appropriate photographs. For this reason, with the attachment 1 of this embodiment, when the camera 210 of the tablet terminal 2 is not in use, the opening/closing unit 110 is left unfolded to cover the camera 210, as shown in FIG. 5(a), thereby preventing the lens of the camera 210 from becoming scratched or dirty during work. On the other hand, when taking photographs with the camera 210 of the tablet terminal 2, the opening/closing unit 110 is folded back to expose the camera 210, as shown in FIG. 5(b). This makes it possible to take images of inspection locations, for example, without using a camera separate from the tablet terminal 2 that has the same functions as the camera 210, and without removing the tablet terminal 2 from the device holding unit 100.

The configuration of the opening/closing section 110 in the device holding section 100 is not limited to a specific configuration. For example, a reversibly foldable opening/closing section 110 may be provided by dividing a resin plate for supporting the tablet terminal 2, sandwiching the resin plates between pieces of cloth, and sewing them together to create the device holding section 100. Alternatively, a reversibly foldable opening/closing section 110 may be provided by sandwiching a single resin plate with a thin, linear fold between pieces of cloth, and sewing them together to create the device holding section 100.

If the opening/closing section 110 is provided on the device holding unit 100, the portion of the first part of the holding member 102 that overlaps with the opening/closing section 110, such as the fastening member 105, cannot be attached to the device holding unit 100, which may result in the tablet device 2 not being able to be held stably. For this reason, in the wearing device 1 of this embodiment, as illustrated in FIG. 5(b), a reinforcing member 111 is provided in the upper left corner of the device holding unit 100, which is opened by folding back the opening/closing section 110, to which the first part of the holding member 102, such as the fastening member 105, can be sewn. For example, as illustrated in FIG. 6, the reinforcing member 111 has a first part 111a extending from the upper left corner along the top edge of the opened device holding unit 100 as viewed by the worker 3 wearing the wearing device 1, and a second part 111b extending from the upper left corner along the left edge. The first portion 111a and second portion 111b of the reinforcing member 111 may be made by sewing separate belt-shaped pieces of cloth (fabric) together in an L shape, or by folding a single belt-shaped piece of cloth (fabric) into an L shape.

The first portion 111a of the reinforcing member 111 extends beyond the boundary (fold line 110a) of the opening/closing section 110 to the portion of the device holding section 100 that holds the tablet terminal 2, and the portion 111c that overlaps with the device holding section 100 is sewn to the device holding section 100. The first portion of the holding member 102 is sewn to the portion of the first portion 111a of the reinforcing member 111 that overlaps with the opening/closing section 110.

The second portion 111b of the reinforcing member 111 extends beyond the boundary (fold line 110a) of the opening/closing section 110 to the portion of the device holding section 100 that holds the tablet terminal 2, and the portion 111d that overlaps with the device holding section 100 is sewn to the device holding section 100. Fastening members 105 and 107 are also sewn to the second portion 111b of the reinforcing member 111. Note that in Figure 6, fastening member 107, which is attached to the portion of the device holding section 100 that holds the tablet terminal 2, is also sewn to the reinforcing member 111, but fastening member 107 may also be sewn directly to the device holding section 100.

In a wearing device 1 having such a reinforcing member 111, the first portion of the holding member 102 and the fastening member 105 described above with reference to Figure 3 are attached to the device holding part 100 via the reinforcing member 111 by, for example, sewing them to the reinforcing member 111. This allows the upper left corner of the tablet terminal 2 held by the surface 101 of the device holding part 100, as viewed from the worker 3 (the area where the camera 210 is located on the back), to be stably held.

The position of the opening/closing part 110 is not limited to the upper left corner of the device holding part 100 as illustrated in FIGS. 1 and 5. For example, if the camera of the tablet terminal 2 held by the device holding part 100 is located in the upper right corner in FIG. 1, the foldable opening/closing part 110 may be provided in the upper right corner of the device holding part 100. Furthermore, the shape of the foldable part of the opening/closing part 110 is not limited to the triangular shape illustrated in FIGS. 5(a) and 5(b), but may also be a substantially rectangular shape that includes all or part of the left end, all or part of the right end, or all or part of the top end of the device holding part 100.

Furthermore, as described above with reference to Figure 3, the wearing device 1 of this embodiment is provided with a hanging band 130 that supports the opened device holding part 100. As illustrated in Figures 4 and 6, the hanging band 130 in the wearing device 1 of this embodiment is made up of a single band (belt) that includes a first hanging part 132 that supports the device holding part 100 at the left end of the device holding part 100, and a second hanging part 134 that supports the device holding part 100 at the right end of the device holding part 100.

The hanging band 130, which consists of a single band, has one end 131 attached to the protective part 120 at a position that is the upper left corner as seen by the worker 3 wearing the harness 1, and the other end 133 attached to the protective part 120 at a position that is the upper right corner as seen by the worker 3 wearing the harness 1. The one end 131 and the other end 133 of the hanging band 130 are, for example, sewn to the protective part 120.

The first hanging portion 132 of the hanging band 130, continuing from one end 131, is attached to the device holding portion 100 so as to support the device holding portion 100 between the end of the device holding portion 100 on the left side as viewed from the worker 3 wearing the harness 1, which is connected to the protective portion 120, and the opposite end. Specifically, as illustrated in FIG. 6, the first hanging portion 132 is sewn to the second portion 111b of the reinforcing member 111, and is attached to the device holding portion 100 via the reinforcing member 111, thereby supporting the opened device holding portion 100. At this time, the first hanging portion 132 is sewn to the second portion 111b of the reinforcing member 111, between the portion of the second portion 111b where the fastening member 105 is sewn and the portion of the fastening member 107 where the fastening member 107 is sewn.

Furthermore, the first hanging portion 132 and the second hanging portion 134 of the hanging band 130 in the wearing device 1 of this embodiment are different portions of a single band. As illustrated in FIG. 6 , the hanging band 130 has, between the first hanging portion 132 and the second hanging portion 134, a first intermediate portion 135 extending along the second portion 111b of the reinforcing member 111, and a second intermediate portion 136 extending along the first portion of the holding member 102. The first intermediate portion 135 is sewn to the second portion 111b of the reinforcing member 111. A section 136a of the second intermediate portion 136 overlapping with a section 102a of the first portion of the holding member 102 sewn to the surface 101 of the device holding unit 100 is sewn to the device holding unit 100 together with the first portion of the holding member 102. Of the second intermediate region 136, the region 136b that overlaps with the region 102b sewn to the second portion 111b of the reinforcing member 111 in the first region of the retaining member 102 is sewn to the reinforcing member 111 together with the first region of the retaining member 102.

The second hanging portion 134 of the hanging band 130, continuing from the other end 133, is attached to the device holding unit 100 so as to support the device holding unit 100 near the right side of the device holding unit 100 as viewed from the worker 3 wearing the harness 1, opposite the end where it connects to the protective portion 120. Specifically, as illustrated in Figures 4 and 6, the second hanging portion 134 is folded back toward the sewn portion of the first portion of the holding member 102 at a position between the top end of the device holding unit 100 and the sewn portion of the first portion of the holding member 102, and continues to the second intermediate portion 136. In other words, the end of the second hanging portion 134 opposite the other end 133 is sewn to the surface 101 of the device holding unit 100 together with the first portion of the holding member 102, allowing the second hanging portion 134 to support the opened device holding unit 100.

In this way, by supporting the open device holding unit 100 with the first hanging portion 132 on the left side of the tablet terminal 2 and the second hanging portion 134 on the right side as viewed from the worker 3, left-right tilt (twist) of the device holding unit 100 is suppressed, and the device holding unit 100 can be stably supported. Furthermore, by creating the hanging band 130 from a single belt and attaching the first intermediate portion 135 and the second intermediate portion 136 between the first hanging portion 132 and the second hanging portion 134 to the device holding unit 100 via the reinforcing member 111, the strength of the upper end of the device holding unit 100 can be increased. This reduces the burden on the worker 3, who must be careful not to drop the tablet terminal 2 due to the tilt of the open device holding unit 100, for example. Furthermore, because the device holder 100 can be stably supported, it is possible to prevent a decrease in the visibility and operability of the touch panel display 200 of the tablet terminal 2 due to shaking of the device holder 100, etc. Note that the configuration and attachment method of the first intermediate portion 135 and second intermediate portion 136 of the hanging band 130 are not limited to the configuration and attachment method described above with reference to Figure 6.

Furthermore, the first hanging part 132 and the second hanging part 134 that support the opened device holding part 100 may have different distances from the top end of the device holding part 100 to the position that supports the device holding part 100, as shown in Figures 4 and 6, for example. In this case, for example, by moving the attachment position of the second hanging part 134 on the opposite side (i.e., the right end) of the device holding part 100 from the left end where the opening/closing part 110 is provided closer to the top end, it is possible to suppress a decrease in the ease of holding the tablet terminal 2, the operability of the tablet terminal 2, etc.

Figure 4 shows an example of a method for placing and holding a tablet terminal 2 with a case 4 attached on the surface 101 of the device holding unit 100. When placing the tablet terminal 2 on the surface 101 of the device holding unit 100, the fastening members 104 and 106 at the left end of the device holding unit 100 are removed from the holding members 102 and 103, respectively, and the tablet terminal 2 with the case 4 attached is inserted between the surface 101 of the device holding unit 100 and the second and third portions of the holding members 102 and 103. Then, for example, the fastening members 104 and 106 are fastened to the holding members 102 and 103, adjusting them so that the tablet terminal 2 with the case 4 attached is properly held by the second and third portions of the holding members 102 and 103. This adjustment may include, for example, adjusting the fastening positions of the fastening members 105 and 107 at the right end of the device holding unit 100 and the holding members 102 and 103. By adjusting the fastening positions of the holding members 102 and 103 and the fastening members 104 to 107, the tablet terminal 2 placed on the surface 101 of the device holding unit 100 can be properly held in place to prevent it from falling off.

The case 4 is not limited to a specific configuration as long as it is compatible with the type of tablet device 2 (model, external dimensions, etc.). The case 4 may be a hard case that includes components made of a hard material and provides one or more of the following functions to the tablet device 2: impact resistance, waterproofing, dustproofing, etc. The case 4 may be separate from the tablet device 2 (detachable), or may be integrated with the housing of the tablet device 2. Note that the tablet device 2 held by the device holding unit 100 may not have the case 4 attached.

The configuration of the members used to hold the tablet terminal 2 on the surface 101 of the device holding unit 100 is not limited to the combination of holding members 102, 103 and fastening members 104-107 described above with reference to Figure 4. For example, the members for holding the tablet terminal 2 may be a combination of holding members extending along the left, bottom, and right edges of the tablet terminal 2 placed on the surface 101 of the device holding unit 100 as seen by the worker 3, and fastening members provided on the top edge.

As such, when inserting a tablet terminal 2 from the right side of the device holding unit 100 to which the second hanging part 134 is attached, if the second hanging part 134 is attached in a position corresponding to the insertion port, for example, the second hanging part 134 may get caught when inserting the tablet terminal 2, preventing smooth insertion. Furthermore, for example, when worker 3 operates the tablet terminal 2 with his or her right hand, if the second hanging part 134 is attached in a position corresponding to the insertion port, the second hanging part 134 may hit the right hand, making operation difficult. Therefore, for example, as illustrated in Figures 4 and 6, by attaching the second hanging part 134 to the device holding unit 100 in a position close to the top end of the device holding unit 100, it is possible to prevent the second hanging part 134 from getting caught when inserting the tablet terminal 2 and to prevent the presence of the second hanging part 134 from making it difficult to operate the tablet terminal 2.

In addition, in the wearing device 1 of this embodiment, either the first hanging portion 132 or the second hanging portion 134 of the hanging band 130 may be omitted. For example, if the worker 3 operates the tablet terminal 2 with his or her right hand, omitting the second hanging portion 134 at the right end can prevent a decrease in operability due to the presence of the second hanging portion 134. Furthermore, the hanging band 130 may be separated into a first band having the first hanging portion 132 and a second band having the second hanging portion 134, for example, by omitting part or all of the first intermediate portion 135 and the second intermediate portion 136.

Furthermore, the wearing device 1 of this embodiment is configured to enable the entire series of tasks, including tasks using the tablet device 2, to be performed safely and efficiently. In other words, the wearing device 1 of this embodiment is designed so that carrying the tablet device 2 does not interfere with tasks that do not use the tablet device 2.

Figure 7 is a partially enlarged perspective view illustrating an example configuration of an article hanging section in a worker's harness according to one embodiment. Figure 8 is a rear view illustrating another example of use of a worker's harness according to one embodiment.

The work performed by the worker 3 wearing the harness 1 of this embodiment may include work using the tablet terminal 2, and is not limited to a specific task. The work performed by the worker 3 wearing the harness 1 may be inspection work on roads, tunnels, bridges, etc., as described above. Furthermore, since standards (e.g., color, etc.) are established for the clothing and various harnesses worn by the worker 3 depending on the type of work, it is preferable that the harness 1 meets such standards. For example, workers 3 working on highways, etc., are required to wear work clothes made of highly visible fabrics (e.g., fluorescent orange-red) or retroreflective materials so that they can be clearly seen by passing vehicles, etc. When such workers 3 wear the harness 1, it is preferable to select the color, etc., of the material of the harness 1 to minimize the reduction in visibility caused by the harness 1.

For example, in the wearing device 1 illustrated in FIG. 1 , it is preferable to use fabric of a color that is the same as or similar to the color of the work clothes worn by the worker 3 (e.g., fluorescent orange-red, etc.) on the surface of the device holding unit 100 opposite the surface 101 that holds the tablet terminal 2. In other words, on the surface that is visible in front of the worker 3 when the device holding unit 100 is closed, the color of the work clothes that is hidden by the wearing device 1 can be compensated for by the color of the device holding unit 100 of the wearing device 1, thereby preventing a decrease in visibility. Furthermore, by using a highly visible color (e.g., fluorescent orange-red, etc.) for the surface that is visible in front of the worker 3 when the device holding unit 100 is closed, a highly visible color can be added, for example, in cases where high visibility is not required for the color of the work clothes worn by the worker 3 (e.g., when gray, navy blue, etc. work clothes are acceptable). Note that the highly visible color is not limited to the fluorescent orange-red illustrated, and other colors may be used.

The wearing device 1 illustrated in FIG. 1 has four reflective tapes 112-115 extending in the left-right direction on the surface that is visible in front of the worker 3 when the device holding unit 100 is closed. Each of the reflective tapes 112-115 is a fabric tape with a retroreflective material on the outward-facing surface, and is sewn to the device holding unit 100. Three of the four reflective tapes 112-115, 112-114, each have five loop portions divided in the left-right direction. For example, the reflective tape 112 is sewn at six locations, including both ends in the left-right direction, to the surface 108 of the device holding unit 100 opposite the surface 101 that holds the tablet terminal 2, as shown in FIG. 7. The portions of the reflective tape 112 between the two adjacent sewn portions and the surface 108 of the device holding unit 100 form loop portions 112a, 112b, etc. Although not shown, similar loop portions are also provided on reflective tapes 113 and 114.

Pens 5, chalk, tools, inspection equipment, whistles, and other items carried during work can be hung on the loop portions of the reflective tapes 112-114 using a hook member such as a carabiner 6. Items such as pens 5 are connected to the hook member such as a carabiner 6 using, for example, an elastic curl cord 7 or a wire reel. By fastening the hook member to the loop portions, various items that can be used during work can be carried efficiently and the items can be prevented from falling. The loop portions of the reflective tapes 112-114 are not limited to the pens 5 and other items described above; they can also be used to hang and carry small items such as pouches and bags that hold pens 5 and other items.

In addition, by providing reflective tapes 112-115, for example, portions of the work clothing that use retroreflective material and are therefore hidden by the harness 1 can be compensated for by the reflective tapes 112-115 provided on the device holding portion 100 of the harness 1, thereby preventing a decrease in visibility. Furthermore, by providing reflective tapes 112-115, visibility can be increased, for example, in cases where high visibility is not required for the color of the work clothing worn by the worker 3. Note that while the harness 1 shown in FIG. 1 has four reflective tapes 112-115, the number of reflective tapes is not limited to four. Furthermore, the number of reflective tapes provided with the above-mentioned loop portions and the number of loop portions provided on one reflective tape are not limited to any particular number.

Furthermore, the wearing device 1 is not limited to loops using the above-mentioned reflective tape 112-114, and may be provided with loops using a cloth (fabric) other than reflective tape. For example, the loop 116 at the upper right end of the device holder 100 shown in FIG. 1 can be used to attach a camera separate from the tablet terminal 2, and may be provided with black cloth.

Furthermore, work using the tablet terminal 2 may be performed by a worker 3 wearing a fall arrest device (safety belt), sometimes called a full harness. For this reason, the pair of shoulder straps 140, 145, pair of waist straps 150, 155, and cushion part 160 described above in the harness 1 of this embodiment are preferably designed to allow a worker 3 wearing a fall arrest device to easily wear the harness 1 and perform work safely.

For example, as shown in Figure 8, the back of a worker 3 wearing a fall arrest device 9 has a lanyard attachment part 900 to which one end of a lanyard (lifeline) is attached. If the lanyard attachment part 900 of the fall arrest device 9 overlaps with the cushion part 160 of the attachment device 1, the lanyard attachment part 900 may be pressed against the back of the worker 3, causing discomfort or pain. For this reason, it is preferable that the pair of shoulder strap parts 140, 145, pair of waist strap parts 150, 155, and cushion part 160 of the attachment device 1 of this embodiment be arranged so that the attachment device 1 can be worn without interfering with the lanyard attachment part 900 of the fall arrest device 9, as shown in Figure 8.

Furthermore, when a worker 3 wearing a fall arrest device 9 also wears the harness 1, before, during, or after work in which the lanyard hook is attached to a lifeline or scaffolding erected at the work site, the worker may detach the hook from the lifeline or scaffolding to move around or perform other work. For this reason, the harness 1 of this embodiment preferably has hanging portions 122, 123 such as D-rings on the protective portion 120 for hanging the lanyard hook detached from the lifeline or scaffolding, as illustrated in Figures 1, 2, and 4, for example. In this way, the worker can hang the lanyard hook detached from the lifeline or scaffolding on the hanging portions 122, 123, leaving both hands free to operate the tablet device 2 or perform other tasks.

As mentioned above, the wearing device 1 described with reference to Figures 1 to 8 is merely one example (one embodiment) of the wearing device 1 according to the present invention. The wearing device 1 according to the present invention may be modified in configuration, some components may be omitted, or other components not illustrated may be added, without departing from the spirit of the present invention. For example, the device holding part 100 and the protective part 120 in the wearing device 1 may be connected by a stepless hinge or the like, so that the angle of the device holding part 100 relative to the protective part 120 can be adjusted and maintained at a fixed angle.
