Description

Application for application of Article 30, Paragraph 2 of the Patent Act Published on January 20, 2015 in distribution distribution material (Capybara-san PC Cushion)

The present invention relates to an operation aid that is placed on a table and used with a part of the upper limb resting on it.

Regarding the operation aid, various forms have been proposed, for example, as disclosed in Patent Documents 1 and 2 mentioned below. However, since these operating aids are used by resting a part of the upper limb (hand, wrist, forearm, elbow, upper arm, and shoulder), specifically the hand, wrist, or forearm, they are not effective in reducing fatigue of the upper limb. Although it is effective, it is not very effective in reducing fatigue in the neck, back, and lower back.

Fatigue of the neck, back, and lower back is related to the posture of the upper body during operation. That is, compared to when the posture of the upper body is proper, the burden placed on the neck, back, and lower back is greater when the posture is leaning forward. There is also the possibility of developing medical conditions that interfere with daily life, such as cervical disc herniation or lumbar disc herniation.

The carried article 12 preferably has an exterior made of cloth or the like and is preferably filled with an elastic material, and has elasticity as a whole. As the elastic material in this case, for example, low resilience foam, high resilience foam, synthetic cotton, natural cotton, down, feather, a combination thereof, etc. can be used as appropriate. In addition, since the held article 12 does not necessarily have to be highly elastic as long as it can be deformed, in this case, instead of the elastic material, or in addition to the elastic material, for example, synthetic resin beads, synthetic Resin pipes, buckwheat hulls, combinations thereof, etc. may be used as appropriate.

Furthermore, as shown in FIGS. 4(A) to 4(C), the carried article 12 has a recess 12a at or near the center in the front height direction, and the deepest part of the recess 12a or the deepest part thereof. Two deformable connection auxiliary parts 12b are provided in the vicinity so as to substantially face the two connection members 11a, and each connection auxiliary part 12b has a connection member 12c. Examples of the connecting member 12c include a circular string sewn to the auxiliary connection part 12b with a thread (see FIG. 5), the other of the convex and concave members of a snap button, and the hook-side member and loop-side member of a hook-and-loop fastener. Any means that can easily and safely connect and disconnect can be used as appropriate.

Furthermore, since the carried article 12 also plays a role of giving the operator 30 a sense of relief and security, it is preferably a stuffed toy imitating a character or an animal. In this case, the connection auxiliary part 12b is made to resemble a finger, and eyes, ears, a mouth, feet, etc. are added to the held article 12 as appropriate. Such a stuffed toy can provide the operator 30 with a higher sense of relief and security, and can also provide a comfortable feeling.

Next, referring to FIG. 5, a procedure for connecting and disconnecting the auxiliary tool main body 11 and the carried article 12 will be described.

When connecting the auxiliary tool main body 11 and the held article 12, as shown in FIG. 11a, as shown in FIG. 5(B), connect the connecting auxiliary part so that the connecting member (annular string) 12c of the held article 12 is firmly engaged with the connecting member (button) 11a of the auxiliary tool main body 11. 12b is moved. Further, when connecting means other than those described above are used as the connecting members 11a and 12c, for example, when snap buttons are used, the connection can be made by engaging the convex member and the concave member with each other, and the connecting members 11a and 12c When a hook-and-loop fastener is used as the hook-and-loop fastener, the hook-side member and the loop-side member may be engaged with each other for connection.

As mentioned above, the assisting tool main body 11 is provided with two connecting members 11a spaced apart from each other in the longitudinal center position on the back side (see FIGS. 3(B) to 3(D)). ), the held article 12 is provided with a recess 12a at or near the center in the front height direction, and two deformable connection auxiliary parts 12b are provided at or near the deepest part of the recess 12a. Each connection auxiliary portion 12b is provided with a connection member 12c so as to substantially face each connection member 11a (see FIGS. 4(A) to 4(C)). Therefore, each connection member 11a of the auxiliary tool main body 11 and each connection member 12c of the held article 12 are connected at a position closer to the center in the length direction of the auxiliary tool main body 11.

On the other hand, when releasing the connection between the auxiliary tool main body 11 and the held article 12, as shown in FIG. It is sufficient to extract it from 11a. Further, when connecting means other than those described above are used as the connecting members 11a and 12c, for example, when snap buttons are used, the connection can be released by disengaging the convex member and the concave member, and the connecting members 11a and 12c can be disconnected. When a hook-and-loop fastener is used as the hook-and-loop fastener 12c, the connection can be released by disengaging the hook-side member and the loop-side member. Since the connecting procedure and the disconnecting procedure are simple operations, they do not require much time, and the auxiliary tool main body 11 and the held article 12 can be reliably connected even though they are simple operations.

Next, referring again to FIGS. 1 and 2, a preferred example of a method for using the operation aid 10 in which the aid main body 11 and the held article 12 are connected will be described.

Each of the connection auxiliary parts 12b of the carried article 12 is deformable and has a certain length, so even if the height position of the carried article 12 is slightly different, the auxiliary tool main body 11 placed on the table 40 There will be no misalignment.

Subsequently, the operator 30 places the forearms 32 at both longitudinal ends of the auxiliary device main body 11 while holding the carried article 12 with the upper arm 31, elbow, and forearm 32. Thereafter, the operator 30 operates the keyboard 21 of the computer 20 placed on the desk 40 with his fingertips while looking at the display 22. The maximum length L11 of the auxiliary tool main body 11 is longer than the maximum width W12 of the held article 12, so that the operator 30 can visually recognize the portion on which the forearm 32 can be placed on both lengthwise ends of the auxiliary tool main body 11. Therefore, the action of placing the forearm 32 on the auxiliary tool main body 11 can be performed without difficulty.

In the usage state shown in FIGS. 1 and 2, although the held article 12 is partially deformed in response to the position adjustment and the holding, the posture of the upper body of the operator 30 is Since the held article 12 interposed between the person 30 and the table 40 provides a corrective action, the posture of the upper body does not lean forward excessively. In addition, in the usage state shown in FIGS. 1 and 2, the held article 12 held by the upper arm 31, elbow, and forearm 32 of the operator 30 has its front side in contact with the auxiliary tool main body 11 or the table 40, and its back side. is in contact with the chest 34 and abdomen 35 of the operator 30, the lower end is in contact with the thigh 36 of the operator 30, and the part above the deepest part of the recess 12a is in contact with the auxiliary device main body 11, so that the holding The article 12 does not shift or oscillate during operation.

In this embodiment, the explanation has been made as an operation aid used when operating an electronic device such as a computer placed on a table, but the use is not limited to operating an electronic device such as a computer. It can also be used when doing some kind of work, such as reading or drawing.

Next, the effects obtained by the operation aid 10 in this embodiment described above will be explained. Incidentally, E1 to E8 described later are symbols indicating effects.

(E1) The operation aid 10 has an aid main body 11 on which the forearm 32 of the operator 30 can be placed, and also holds an article 12 that can be held by the upper arm 31, elbow, and forearm 32 of the operator 30. Since the carried article 12 can prevent the upper body from leaning forward, it can contribute to reducing fatigue in the upper limbs as well as the neck, back, and lower back. Furthermore, the held item 12 held by the upper arm 31, elbow, and forearm 32 of the operator 30 also plays a role in giving the operator 30 a sense of relief and security, and thus contributes to reducing mental fatigue during operation. can do. Furthermore, by holding the carried article 12, it is possible to operate electronic equipment such as a computer while maintaining a constant distance between the left and right forearms 32 and between the upper arms 31.

(E2) Since the auxiliary tool main body 11 and the held article 12 each have connection members 11a and 12c for removably connecting each other, the auxiliary tool main body 11 and The held article 12 can be easily connected and disconnected.

(E3) When the auxiliary device main body 11 and the held article 12 have elasticity, the fatigue of the upper limbs can be effectively reduced by the auxiliary device main body 11, and the held article 12 can be held naturally with the upper limbs without discomfort. The sense of relief and security given to the operator 30 can be further enhanced.

(E4) Since the connections between the connecting members 11a of the auxiliary tool main body 11 and the respective connecting members 12c of the held article 12 can be made at a position closer to the center in the length direction of the auxiliary tool main body 11, the operator 30 can attach the forearm to the auxiliary tool main body 11. 32, these connecting members 11a and 12c do not get in the way.

(E5) The maximum length L11 of the auxiliary tool main body 11 is longer than the maximum width W12 of the held article 12, and the forearm 32 can be placed on both ends of the auxiliary tool main body 11 in the length direction from the operator 30. Since it is clearly visible, the action of placing the forearm 32 on the auxiliary tool main body 11 can be performed without difficulty.

(E6) The held article 12 held by the upper arm 31, elbow, and forearm 32 of the operator 30 is in a state where the portion above the deepest part of the recess 12a is in contact with the auxiliary tool main body 11. will not shift or sway during operation.

(E7) When the carried item 12 is a stuffed toy imitating a character or an animal, it is possible to give the operator 30 a higher sense of relief and security, and in addition, it can also give the operator 30 a comfortable feeling. Can be done.

(E8) When the carried article 12 is a stuffed toy imitating a character or an animal, the connecting auxiliary part 12b is made to imitate a finger, thereby eliminating the sense of discomfort with the connecting auxiliary part 12b and improving the external appearance. In addition, it is possible to deepen the attachment and fondness that the operator 30 has for the operation aid 10.

Next, a modification of the operation aid 10 described with reference to FIGS. 1 to 5 will be described. Incidentally, M1 to M5 described later are symbols indicating modified examples.

(M1) Although a case has been shown in which the holding article 12 is provided with the connection auxiliary part 12b and the connection auxiliary part 12b is provided with the connection member 12c (ring-like string, etc.), the connection auxiliary part 12b is eliminated and the connection member 12c is provided. may be provided directly on the held article 12.

(M2) Although the maximum length L11 of the auxiliary tool main body 11 is longer than the maximum width W12 of the held article 12, the maximum length L11 of the auxiliary tool main body 11 is made equal to the maximum width W12 of the held object 12.
