[Description of Embodiments]



[0012] The sheet for assembling a device and the device according to the present invention are described hereinafter in detail. The device constructed using the sheet for assembling a device of the present invention is described first.

[0013] A device 1 shown in Fig. 1 is a device for grabbing/pinching various articles, the device 1 including a movable mechanism body 20, a supporting body 40, and a connecting part 60 that connects the movable mechanism body 20 and the supporting body 40 to each other and holds the movable mechanism body 20 and the supporting body 40 in an angle adjustable manner.

[0014] In the following description, a base end means an end portion on the connecting part side, and a tip end means an end portion opposite to the connecting part. As to the connecting part, similarly, a tip end thereof faces the same direction as the tip ends of the other parts, and a base end of the same faces the same direction as the base ends of the other parts.

<Movable mechanism body>



[0015] As shown in Figs. 1 to 4, the movable mechanism body 20 is composed of:

a base body 22 having a predetermined length and having one or more bent portions;

a drive body 24 disposed parallel to the base body 22 and having one or more bent portions;

a bent portion connecting portion 26 for connecting the base body 22 and the drive body 24 to each other at the bent portions thereof; and

a movable mechanism base end portion 28 for integrating the base body 22 and the drive body 24 with each other at base ends thereof.



[0016] The base body 22, composed of a tip end portion 22a on the tip end side and a base portion 22b on the base end side, is a portion that connects the tip end portion 22a and the base portion 22b, and is provided with one bent portion 22c forming the bent portion. Also, the tip end portion 22a is composed of a plate-shaped portion 22a-1 being plate-shaped and located at the tip end,
a reinforcement portion 22a-2 connected to the plate-shaped portion and consisting of a hollow triangular prism, and a bendable portion 22a-3 being the connection between the plate-shaped portion and the reinforcement portion.
The elongated plate-shaped base portion 22b is hollow as is formed by folding a sheet described hereinafter. Furthermore, the tip end portion 22a is thinner than the plate-shaped base portion 22b, whereby the base portion 22b can freely rotate with the bent portion 22c as a fulcrum. The bent portion 22c is formed by continuously connecting a bottom surface of the reinforcement portion 22a-2 to an edge portion of the tip end of the plate-shaped base portion 22b, the edge portion being located on the side opposite to the supporting body 40, that maximize the movement of the drive body 24.

[0017] The drive body 24 is composed of a first moving portion 24a on the tip end side, a third moving portion 24c on the base end side, and a second moving portion 24b positioned therebetween, and is provided with a first bent portion 24d connecting the first moving portion 24a and the second moving portion 24b, and a second bent portion 24e connecting the second moving portion 24b and the third moving portion 24c. The first moving portion 24a and the second moving portion 24b are of substantially the same length, but may have different lengths. In contrast, the third moving portion 24c is longer than the first moving portion 24a or the second moving portion 24b. With each bent portion, the first moving portion 24a and the second moving portion 24b are rotatable with respect to the second moving portion 24b and the third moving portion 24c, respectively, and the drive body 24 is made thicker than the base body 22 so that the drive body 24 can be prevented from bending toward the side opposite to the supporting body 40 and can be bent efficiently toward the supporting body 40. Specifically, as shown in Figs. 1 and 2, each of the first to third moving portions 24a, b, c is in the shape of a hollow prism (triangular prism in the present embodiment), and the first and second bent portions 24d, e are formed by connecting parts of the edge portions of these triangular prism-shaped bottom surfaces on the supporting body 40 side, and the first to third moving portions 24a, b, c are formed by bringing the upper portions of the triangular prism-shaped first to third moving portions 24a, b, c (i.e., at least parts of the edge portions of the triangular prism-shaped bottom surfaces except for the connected parts thereof) into abutment to have a thickness that prevents the first to third moving portions 24a, b, c from bending in a direction opposite to the supporting body. Moreover, the first moving portion 24a and the second moving portion 24b are provided with, on side surfaces thereof on the supporting body 40 side, V-shaped first moving portion auxiliary part 24f and second moving portion auxiliary part 24g for efficiently bending the bent portions. The first moving portion auxiliary part 24f and the second moving portion auxiliary part 24g are provided in such a manner that V-shaped, substantially right angle portions thereof are positioned on the supporting body 40 side. Also, the first moving portion 24a and the second moving portion 24b are connected to each other by part of the edge portions of the bottom surfaces, whereas the second moving portion 24b and the third moving portion 24c are connected to each other by attaching a connecting part 24c-1 (see Fig. 3) to an outer surface of the triangular prism-shaped body of the second moving portion 24b, the connecting part 24c-1 being provided on the bottom surface of the triangular prism-shaped body of the third moving portion 24c. The tip end portion 22a is connected to the first moving portion auxiliary part 24f at a distal end side from the first moving portion 24a of the first moving portion auxiliary part 24f, and the second moving portion auxiliary part 24g is connected to the edge portion of the base portion 22b on the supporting body 40 side at the distal end side from the second moving portion 24b.

[0018] The bent portion connecting portion 26 is provided by connecting the bent portion 22c and the second bent portion 24e to each other. As described hereinafter, the base body 22 and the drive body 24 are connected to each other at the respective bent portions 22c, 24e thereof by forming the base body 22 and the drive body 24 from a continuous sheet, that is, by forming a part of the base portion 22b of the base body 22 and a part of the second moving portion 24b of the drive body 24 from a continuous sheet.

[0019] The movable mechanism base end portion 28 formed by integrating base ends of the base body 22 and the drive body 24 is composed of a movable connecting portion 28a that connects the base body 22 and the drive body 24 in such a manner that the base ends thereof are located in different positions in a height direction, a protruding piece 28b that comes into contact with the connecting part 60 without being tightly fixed thereto, and a biasing part 28c that is located between the protruding piece 28b and the base end of the drive body 24 and connected to the top of the movable connecting portion 28a and the third moving portion 24c. Note that the protruding piece 28b may be movable along a surface of the connecting part 60. The movable connecting portion 28a is formed into a triangular prism (equilateral triangle in the present embodiment) so as to be able to fix the base body 22 and the drive body 24 in a stable manner, and is formed so as the smallest surface (side surface) of the triangular prism to be positioned on the connecting part 60 side. The biasing part 28c is a hollow quadrangular prism and has substantially the same height as the third moving portion 24c.

[0020] A triangle is formed by the base portion 22b, the third moving portion 24c, and the movable connecting portion 28a when viewed laterally, by connecting the tip end side of the third moving portion 24c and the tip end side of the base portion 22b to each other using the bent portion connecting portion 26 and by connecting the base end side of the third moving portion 24c and the base end side of the base portion 22b to each other using the movable connecting portion 28a in such a manner that the base ends are located in different positions in the height direction. Since this triangle is configured so as to be deformable within a range in which the base portion 22b, the third moving portion 24c, and the movable connecting portion 28a virtually do not deflect (a small degree of deflection is inevitable depending on the materials for configuring the base portion 22b, the third moving portion 24c, and the movable connecting portion 28a), the force applied to the third moving portion 24c is transmitted appropriately to the second moving portion 24b, the first moving portion 24a, and the like.

<Supporting body>



[0021] The supporting body 40 is composed of a supporting body main body 42 having a length corresponding to the movable mechanism body 20, and, in the present embodiment, has an elastic portion 46 that is connected to the connecting part 60 and biases the supporting body main body 42.

[0022] The supporting body main body 42 is in the shape of a thumb of a human and has a thick base end and a thin tip end. The supporting body main body 42 is provided with three inclined portions 46a, b, c from the base end to the tip end, forming a wave. Accordingly, by acting with the movable mechanism body, any object can be pinched easily.

[0023] The elastic portion 46 is formed by providing a single sheet in an arc shape, between the base end of the supporting body main body 42 on the side opposite to the movable mechanism body 20 and the base end of the connecting part, the sheet being described hereinafter. Accordingly, connecting the supporting body 40 and the connecting part 60 to each other causes the elastic portion 46 to act as a plate spring, so that when a force acting in the direction opposite to the movable mechanism body 20 is biased to the supporting body main body 42, the supporting body main body 42 is biased in the direction opposite thereto, whereby an object can be pinched in a favorable manner.

<Connecting part>



[0024] The connecting part 60 is configured to hold the movable mechanism body 20 and the supporting body 40, with a predetermined space therebetween. The connecting part 60 is a hollow quadrangular prism and is provided with a taper at the base end thereof tapering from the supporting body 40 side toward the movable mechanism body 20 side. The base end of the supporting body 40 and a tip end 60-1 of the connecting part 60 are connected to each other directly, and the base end of the movable mechanism body 20 and the tip end of the connecting part 60 are connected to each other by fixing a fixing part 62 to the base end 22b of the base body 22, the fixing part 62 being provided at the tip end 60-1 of the connecting part 60, at a position different from (or away from) the connecting position between the supporting body 40 and the connecting part 60. Thus, the movable mechanism base end portion 28 is in contact with the connecting part 60 in a free state. Since the movable mechanism base end portion 28 is in contact with the connecting part 60 in a free state, the angle of the movable mechanism body 20 with respect to the supporting body 40 can freely be adjusted by moving the position of the movable mechanism base end portion 28 on the connecting part 60. Moreover, auxiliary walls 64 are provided on both left and right sides (i.e., the positions sandwiching the movable mechanism base end portion 28) of a surface of the connecting part 60 at the movable mechanism body 20 side, so that the movable mechanism base end portion 28 can be moved without stress.

<Effects>



[0025] When using the device, the device can be operated using various driving members such as a servomotor, and how the device is operated by human fingers is described using Figs. 5 to 8.

[0026] As shown in Fig. 5, a thumb is inserted into the base end of the connecting part 60, and an index finger presses the protruding piece 28b that is brought into abutment with the connecting part 60. Then, when pinching a circular object to be pinched A at the tip end side, the object to be pinched A is placed in the position where the object to be pinched A comes into abutment with a tip end portion of the supporting body main body 42 as shown in Fig. 6, and then the index finger is moved so as to push the index finger toward the tip end side, thereby pushing the protruding piece 28b (not shown) and the biasing part 28c toward the tip end, and consequently, the third moving portion 24c is pushed toward the tip end side, and the second moving portion 24b and the first moving portion 24a are moved toward the supporting body 40, with the second bent portion 24e as a fulcrum, in accordance with the shape of the object to be pinched A, and then the position of the supporting body is kept against the pinching pressure by taking advantage of the action of the elastic portion 46, whereby the object to be pinched A can be pinched. Moreover, in order to hold the object to be pinched A tight, the protruding piece 28b and the biasing part 28c can be pushed toward the tip end side by placing the object to be pinched A on the base portion 22b side and pushing the index finger as shown in Fig. 7. Then the third moving portion 24c is pushed toward the tip end side. In accordance with the shape of the object to be pinched A, the second moving portion 24b with the second bent portion 24e as a fulcrum is moved, and the first moving portion 24a with the first bent portion 24d as a fulcrum is moved toward the supporting body 40 side, so as to hold the object to be pinched A in such a manner to wrap the entire object to be pinched A. Not only the circular object to be pinched A but also a rectangular object to be pinched B shown in Fig. 8 can be held in the same manner of pinching as shown in Fig. 6 and in the same manner of wrapping as shown in Fig. 7.

<Assembly, effects>



[0040] A method for assembling the sheet of the present embodiment, that is, a method for manufacturing the device of the foregoing embodiment, is described hereinafter. Note that the order of formation is merely an example; the device may be assembled in another assembly order.

[0041] First, as shown in Fig. 10, the second moving portion forming portion 244 is folded to form the second moving portion 24b. In other words, starting from the first margin 244d, the second moving portion forming portion 244 is folded and the first margin 244d is attached to the first surface 244a to form a triangular prism. The second moving portion auxiliary part forming portion 248 is folded to integrate, and then the height forming portion 248c is folded to attach the second margin 244e to the second moving portion auxiliary part forming portion 248. In so doing, starting from the first margin 242d, the first moving portion forming portion 242 is also folded and the first margin 242d is attached, to form the first moving portion 24a.

[0042] Next, as shown in Fig. 11, the movable connecting portion forming portion 282 of the movable mechanism base end portion forming portion 280 is folded, to attach the first margin 282d to the front surface portion 222a of the base portion forming portion 222 and attach the second margin 282e to the front surface 282a. Then, as shown in Fig. 12, the margin 286f of the biasing part forming portion 286 is folded, and the margin 286f is then attached to the front surface 286b.

[0043] Subsequently, as shown in Fig. 13, the third moving portion forming portion 246 is folded. Specifically, the first surface 246b, the second surface 246c, and the third surface 246d of the third moving portion forming portion 246 are folded, and the second margin 246e is attached to the first surface 246b, to form a triangular prism. Then, the entire triangular prism is folded toward the movable mechanism base end portion forming portion 280, attaching the first margin 246a to the movable mechanism base end portion forming portion 280, and then the triangular prism shaped-body is folded to attach only a tip end side of the third margin 246f to an outer surface of the triangular prism-shaped body of the second moving portion 24b, to connect the second moving portion 24b and the third moving portion 24c to each other.

[0044] As a result, the drive body 24 is completed.

[0045] In addition, as shown in Fig. 14, the base body forming portion 220 is folded. Specifically, the base portion forming portion 222 is folded to attach the margin portion 222e to the front surface portion 222a, then each surface of the tip end portion forming portion 224 is folded to attach the margin portion 224d to the front surface portion 224a connected to the first side surface, and the plate-shaped body forming portion 226 is attached to the first surface 247b of the first moving portion forming portion 242.

[0046] The movable mechanism body 20 is completed by the foregoing assembly operation.

[0047] The supporting body 40 and the connecting part 60 are assembled next. As shown in Fig. 15, the short surface 610, the first side surface 620, and the second side surface 630 are folded, to stack and attach the first long surface 640 and the second long surface 650 to each other. Further, the first and second side surfaces 420, 430 of the supporting body forming portion 400 are folded separately, to attach the margins 442, 452.

[0048] Then, the first and second elastic portion forming portions 462, 464 are attached, completing the supporting body 40.

[0049] Finally, as shown in Fig. 16, the first margin 604 of the connecting part 60 is attached to the movable connecting portion, and the second margin 606 is attached to the base end of the base portion so as to wrap the second margin 606 therearound.

[0050] The sheet of the present embodiment is made out of paper, and an adhesive is used to attach each margin. Any adhesion method can be used for adhering/attaching, and not only various adhesives but also heating, welding and the like can be used depending on the material of the sheet.

[0051] Note that the sheet for assembling a device and the device according to the present invention are not limited to those of the foregoing embodiment, and the present invention can be modified in various ways within the scope of the present invention.

[0052] For example, the device of the present invention described above may be formed by connecting the separately produced parts by means of adhesion using welding or an adhesive without using the sheet of the present invention described above.
In addition, in a case where a plurality of bent portions exist, it is sufficient that at least one of the bent portions be connected, and all of the plurality of bent portions do not need to be connected.

[0053] The thickness of the tip end portion 22a of the base portion 22b does not need to be smaller than the thickness of the base portion 22b. Moreover, the device of the present invention described above may be constructed so as to be entirely or partially in the form of an assembled device by means of a method of pouring a material such as resin into a mold, without using the sheet of the present invention described above.

[0054] Furthermore, the elastic portion 46 described above does not need to be provided.

[0055] Also, an example in which the supporting body is configured without any movable mechanism has been described above, but the configuration of the supporting body is not limited thereto; the movable mechanism body can be installed as the supporting body, and the supporting body can be configured with two movable mechanism bodies.

[0056] In addition, the movable mechanism body and the supporting body can be connected to a drive mechanism such as a motor so as to be configured to operate automatically.
