However, in the invention of the piggyback sea otter in Patent Document 1, since it is only placed on the top plate of the desk, it is not possible to support the chest or the like leaning forward, and the support of the chest or the like is insufficient. In the invention of the head holder of Patent Document 2, when the base is placed on the knee of another worker on the top plate, the support column on which the jaw is received wobbles and the head is not sufficiently supported, which causes a burden on the knee. There was a case. The invention of the auxiliary tool of Patent Document 3 could not support the chest and the like tilted forward as in the invention of Patent Document 1, even if the spring was provided, and the support of the chest and the like was insufficient. ..

It is well known that personal computers are widely used because personal computers are extremely useful for accurately and quickly processing and storing vast amounts of information that should be generated and handled in the field such as business. Since a personal computer is generally placed on a desk and used, a worker who handles information such as business will continue to work for a long time toward the personal computer placed on the desk. In that case, you will have to keep facing the desk for a long time, so you will not be moved except for the fingertips necessary for computer work, and the neck that continues to support the heavy head and the shoulders that connect to it will have neck pain and stiff shoulders due to so-called poor blood circulation. Will be generated. In addition, it is not uncommon for eye fatigue to occur due to stiff shoulders and the like.
Forcing workers to work on their desks with a personal computer while having such a physical burden is not only painful for the workers, but also reduces work efficiency and hinders the smooth operation of the business. There was a problem.

The present invention has been made to solve the above-mentioned problems, and supports the chin of a worker who unconsciously takes a forward leaning posture while having a heavy head when working on a desk such as a personal computer. The purpose of the present invention is to provide a death cushion that can reduce the burden on the neck, shoulders, etc. while promoting the correction of the forward leaning posture, and is easy to move according to the working position, and the death cushion main body used for the death cushion. ..

In order to achieve the above object, the death cushion main body and the death cushion of the present invention have the following configurations.

The terminal in the front direction of the base support member 41 may be slightly upward in order to facilitate holding the end portion of the top plate 80 of the desk in combination with the pressure contact member 51 described later.

The strut shaft 21, that is, the jaw receiving portion 22, can be moved in the vertical direction by rotating the jaw receiving portion 22 and the positioning nut 24 provided at the lower end with respect to the strut shaft 21. This is because the screw thread 23, which is the first positioning means, and the nut 35, which is the second positioning means, are screwed together. The jaw receiving portion 22 can have various shapes, but the jaw receiving portion 22 may rotate according to the rotation of the strut shaft 21, and the jaw receiving portion 22 has a cushion 70 as described later. When wrapped in, for example, a disk shape is preferable as a shape that easily rotates in the wrapped state and easily receives the jaw of the worker P.

A description will be given when the death cushion main body 1 (FIG. 2) is supported by the edge of the desk top plate 80 based on FIGS. 3 and 4. FIG. 4 is a view of FIG. 3 from the A direction (front surface). Since the worker P uses his / her jaw on the jaw receiving portion 22 from the rear surface side of the death cushion 90A (see FIG. 20), the left and right sides of FIG. 4 are the left and right sides as seen from the worker P. The same applies to FIGS. 5 to 7. The base support member 41 includes a flat plate-shaped base support member vertical piece 41a and a base support member horizontal piece 41b, and the base support member 41 is attached to the extension holding member 32 by the base support member vertical piece 41a. It is connected and supported by the edge of the desk top plate 80 by the base support member horizontal piece 41b. Then, in order to support the death cushion main body 1 (FIG. 2) more stably, it is preferable that the base support member 41 is formed so as to extend perpendicularly to the axis M toward the front surface. Since the jaw receiving portion 22 can move in the vertical direction within a range corresponding to the length of the screw thread 23 which is the first positioning means formed below the strut shaft 21, the movable range is shown in FIGS. 3 and 4. .. The same applies to FIGS. 5 to 9 and 12 and 13 described later.
In the death cushion main body 1 (FIG. 2), the strut shaft 21 may be on the rear surface side of the holding portion 30. In this case, the nut 35 and the guide portion 36 also need to be provided on the rear surface side of the holding portion 30. When the support column 21 is on the rear surface side, for example, if the base portion 40 is made heavy, the death cushion main body 1 (FIG. 2) is supported by the edge portion of the top plate 80 of the desk without falling to the rear surface side.

A modified example of the death cushion main body 1 (FIG. 2) will be described with reference to FIGS. 5 and 6. The death cushion main body 1A of the modified example of FIG. 5 has an inverted U shape in which the holding portion 30A is closed, and the two first auxiliary bridge holding members 33A form a cross mark (a pair of extension holding members). 32A, the bridge holding member is 31A, and the base support member is 41A). In the death cushion main body 1B of the modified example of FIG. 6, the holding portion 30B forms a substantially sail shape of a yacht. The holding portion 30A in FIG. 5 has a shape symmetrical with respect to the axis M in the left-right direction, while the holding portion 30B in FIG. 6 has a shape substantially symmetrical with respect to the axis M, that is, a shape slightly distorted in the left-right direction. Even if the shape is like the holding portion 30B provided with the pair of extension holding members 32B, the cushion 70 to be described later can be held (the base support member is 41B).
Further, for example, when the upper portion of the holding portion 30B is lengthened with respect to the death cushion main body 1B, the bridge holding member 31B and the first auxiliary bridge member 33B are moved upward accordingly, and the nut 35 is moved to the first auxiliary bridge. When moved to the holding member 33B, the first auxiliary bridge holding member 33B becomes the bridge holding member 31Bα. In this case, the first auxiliary bridge holding member is located above the bridge holding member. This is because the vertical positional relationship between the bridge holding member and the auxiliary bridge holding member may be arbitrary. Further, it is natural that the auxiliary bridge member is unnecessary if it is possible to have the function as the holding portion without the auxiliary bridge holding member.

The death cushion main body 1C will be described with reference to FIG. 7. The holding portion 30C of the death cushion main body 1C is symmetrical with respect to the axis M in the left-right direction, and is configured to include a single flat plate-shaped member 32C straddling the axis M. The second positioning means 35 is provided on the flat plate member 32C. The auxiliary piece 39 is provided to separate the nut 35 from the flat plate member 32C in order to leave a gap between the positioning nut 24 and the flat plate member 32C so that the positioning nut 24 can rotate. be. Therefore, if the flat plate-shaped member 32Cα having a raised portion is formed instead of the auxiliary piece 39, the auxiliary piece 39 is unnecessary. For that purpose, since the flat plate-shaped member 32C has a single shape, molding with plastic can be used. Moreover, if it is molded from plastic, it is possible to reduce the manufacturing cost. The base portion 40 (not shown) is formed by connecting the base support members 41 to the flat plate-shaped member 32C at both left and right ends of the flat plate-shaped member 32C.

The death cushion main body 1D, which is a modified example, will be described with reference to FIGS. 8 and 9. In the death cushion main body 1D, the support shaft 21D is on the rear surface side of the holding portion 30D. The left and right sides shown in FIG. 9 are opposite to the left and right sides shown in FIG. 4 and the like because the worker P uses the death cushion main body 1D from the support column shaft 21D on the rear surface side of the holding portion 30D. In this case, for example, if the base support member 41 is made heavy, the death cushion main body 1D is supported by the edge of the top plate 80 of the desk without falling to the rear surface side.
In the death cushion main body 1D, the first positioning means is a combination in which the female screw portion 21d provided inside the support column shaft 21D and the male screw 25d connected to the grip portion 25 are screwed together. On the other hand, the second positioning means is a fastener 35d on the axis M provided on the bridge holding member 31D. The grip portion 25 is rotatably supported by the bridge holding member 31D by fasteners 35d and screws. The guide portion 36D is fixed to a portion where the pair of extension holding members 32D are bonded inside the pair of extension holding members 32D by screws. A detent screw 37 penetrates the extension holding member 32D and reaches the detent groove 21e slightly below the guide portion 36D so that the strut shaft 21D does not rotate. The length of the detent groove 21e in the longitudinal direction is slightly longer than the movable range. Since the bridge holding member 31D is located at the lower end of the holding portion 30D, the pair of extension holding members 32D are connected to the bridge holding member 31D at both ends of the bridge holding member 31D and are extended upward.

10 is a partially enlarged view of the portions of the first and second positioning means and the detent screw 37 of FIGS. 8 and 9. FIG. 10 is a cross-sectional view taken along the line CC of FIG. 11 (b).
Descriptions of the first and second positioning means and the like will be added based on FIGS. 10 and 11. In FIG. 10, the male screw 25d extending from the inside of the support column shaft 21D is fixed to the grip portion 25. As shown in FIGS. 10 and 11B, the holding portion 25b in which the male screw 25d is extended downward is sandwiched between the upper end portion 25e of the gripping portion 25 and the upper end portion 25f of the gripping portion, and is held by a screw. It is rotatably supported by the recess 35a of the fastener 35d fixed to the member 31D. On the other hand, as shown in FIG. 11A, since the detent screw 37 is in contact with the strut shaft 21D, for example, as shown in FIG. 910, the grip portion 25 is rotated in the F direction to rotate the strut shaft. Even if the 21D is moved upward and the grip portion 25 is rotated in the E direction to move the support shaft 21D downward, the support shaft 21D does not rotate.

Based on FIGS. 12 and 13, the death cushion main body 1E further provided with the pressure contact portion 50 formed at the lower end of the holding portion 30E and press-contacting the edge portion of the top plate 80 of the desk from below will be described. FIG. 13 is a view of FIG. 12 as viewed from the G direction (front surface).
In the death cushion main body 1E, the first positioning means is the six positioning through holes 21F provided in the support column shaft 21E, and the second positioning means is the positioning convex portion 35G provided in the bridge holding member 31E. The guide portion is a guide convex portion 36E formed inside the pair of extension holding members 32 at a portion where the pair of extension holding members 32 are connected. The guide convex portion 36E has a raised gap so that the support column shaft 21E can slide, following the method of forming the positioning convex portion 35G described later. The strut shaft 21E is bent substantially vertically in the front direction at the upper end, and the jaw receiving portion 22E is connected thereto.

The pressure contact portion 50 includes a pair of pressure contact members 51 having flexibility, and one of the pair of pressure contact members 51 is below the base portion 40, that is, the base support member 41 at predetermined intervals, respectively, and the holding portion 30E. It is connected to the. The holding portion 30E below the base portion 40 corresponds to the portion of the extension holding member 32 between the lower surface and the lower end of the top plate 80 of the desk or the first auxiliary bridge holding member 33E. With respect to a predetermined interval, in the case of the first auxiliary rack holding member 33E, the maximum interval is the interval to both ends thereof, and in the case of the extension holding member 32, the interval between the extension holding members 32. On the other hand, if the holding portion 30 is a single flat plate-shaped member 32C, the maximum is the width to both ends of the flat plate-shaped member 32C with respect to the predetermined interval. In FIG. 13, the pressure contact member 51 is connected to the lower ends of the pair of extension holding members 32. For example, if the pressure welding member 51 and the pair of extension holding members 32 are each formed of an iron flat plate and connected by welding, the pressure welding member 51 can be made flexible. Any known technique including a clamp can be used as the pressure contact portion.
At the end portion 52 in the front surface direction of the pressure contact member 51, the distance L1 between the end portion 52 and the base support member 41 is smaller than the thickness L2 of the top plate 80 of the desk. When the desk top plate 80 is inserted between the base support member 41 and the pressure contact member 51, the pressure contact member 51 has flexibility, so that the distance L1 expands to L2, and the distance L2 becomes L1 accordingly. The pressure contact portion 50, that is, the death cushion main body 1E is supported by the edge portion of the top plate 80 of the desk due to the restoring force that tries to return to. Since the tip of the end portion 52 is bent in the direction opposite to that of the desk top plate 80, the desk top plate 80 is easily inserted between the base support member 41 and the pressure welding member 51. Therefore, in this case, even if the column shaft 21E is on the rear surface side of the holding portion, it is not always necessary to make the base support member heavier.

14 (a) is a partially enlarged view when the positioning through hole 21F of FIGS. 12 and 13 and the positioning convex portion 35G are combined, and FIG. 14 (b) is a sectional view taken along the line H-H of FIG. 14 (a).
As shown in FIG. 14A, two slits are inserted in the longitudinal direction across the strut shaft 21E at a position where the lateral direction of the bridge holding member 31E is divided into three equal parts, and the portion between the two slits is inserted. , A convex through hole 35 g corresponding to the positioning through hole 21F which is the first positioning means is opened. After that, as shown in FIG. 14B, a portion between the two slits is raised to open a gap so that the support shaft 21E can slide in the gap. Positioning of the support column shaft 21E can be performed by communicating the positioning through hole 21F and the convex through hole 35g and then inserting the shaft of the positioning screw 38 into both holes.
Further, a spring 38g (not shown) locked to the head of the positioning screw 38 can be provided between the head of the positioning screw 38 and the bridge holding member 31E. After pulling the head of the positioning screw 38 in the direction away from the bridge holding member 31E, the support column shaft 21E is slid to an appropriate position, and the positioning through hole 21F and the convex through hole 35g are communicated with each other to connect the head of the positioning screw 38. When free, the elastic force of the spring 38g allows the shaft of the positioning screw 38 to communicate with both holes. In this case, since the positioning screw 38 is attached to the positioning convex portion 35G, it should be treated as a second positioning means. On the other hand, when the spring 38g is not provided, the positioning screw 38 functions as an auxiliary means of the first or second positioning means.
According to the position of the positioning through hole 21F, the position of the support shaft 21E in the vertical direction can be selected according to the position of the jaw of the worker P. Since the death cushion main body 1E of FIG. 13 has six positioning through holes 21F, it is possible to select the position in six stages.

Based on FIG. 15, the death cushion main body 1F provided with the power cordless lighting 60 on the front surface thereof will be described. The lighting 60 includes a lighting main body 63, a lighting pedestal 61 that receives the lighting main body 63, and a lighting support portion 62 that connects the lighting pedestal 61 to a pair of extension holding members 32 by two screws. Since the illumination support portion 62 has a U-shaped notch that can accommodate the outer diameter of the column shaft 21, it can be easily attached to or detached from the extension member 32. When the lighting is insufficient in the environment where the worker P works on the desk, it is preferable to use the death cushion main body 1F provided with the lighting 60. The lighting is timely selected from known lighting. With power cordless lighting with a built-in alkaline battery or the like, it is not necessary to take power from an outlet, so the Death Cushion body 1F can be used wherever you like without being bothered by the power cord. On the other hand, if you want to save battery power, you can use a light with a power cord. The angle of the light emitted from the illumination surface 63a can be adjusted by bending the illumination pedestal 61 downward. It should be noted that the use of the death cushion main body 1F means that the death cushion using the death cushion main body 1F is substantially used.

Based on FIG. 16, the death cushion 90 in which the cushion 70 provided with the jaw cushion 76 is held in the death cushion main body 1 (FIG. 1) will be described. For the cushion 70 and the chin rest cushion 76, a flexible material such as urethane foam or a rubber material can be used. The chin rest cushion 76 is held in contact with the upper surface of the chin rest portion 22. The cushion 70 is held in contact with the holding portion 30 by the support piece 33a on the opposite side of the base portion 40. The cushion 70 placed and held on the support piece 33a is a pair of hook-and-loop fasteners 77 and 77A connected to the cushion 70 at different positions in the vertical direction, for example, on the front side of the death cushion main body 1 (FIG. 1). Are held by engaging each pair in pairs. In addition, the cushion 70 can be held by tying it with a string or putting a large rubber band on it. The chest of the worker P is cushioned 70, and the jaw of the worker P is cushioned by the chin cushion 76, so that the death cushion 90 can be comfortably used. Further, since the death cushion 90 has an arrowhead shape toward the upper side, the workability is excellent when the worker P extends his arm from the rear surface side to the front surface side to perform the work.

Based on FIG. 17, the death cushion 90 in which the cushion 70 provided with the jaw cushion 76 is held in the death cushion main body 1 (FIG. 2) will be described. For the cushion 70 and the chin rest cushion 76, a flexible material such as urethane foam or a rubber material can be used. The chin rest cushion 76 wraps the chin rest portion 22. In order for the jaw support cushion 76 to serve as a cushioning material between the jaw support portion 22 and the jaw of the worker P, the jaw support cushion 76 may be held on the upper surface of the jaw support portion 22. The cushion 70 wraps most of the support shaft 21 and the holding portion 30 below the jaw receiving portion 22 inside. After wrapping the death cushion body 1 (FIG. 2) as described above, the cushion 70 is connected to the cushion 70 on the front side of the death cushion body 1 (FIG. 2), for example, at different positions in the vertical direction. The hook-and-loop fasteners 77 and 77A are held by engaging each pair in pairs. In addition, the cushion 70 can be held by tying it with a string or putting a large rubber band on it. The chest of the worker P is cushioned 70, and the jaw of the worker P is cushioned by the chin cushion 76, so that the death cushion 90 can be comfortably used. Further, since the death cushion 90 has an arrowhead shape toward the upper side, the workability is excellent when the worker P extends his arm from the rear surface side to the front surface side to perform the work.

Based on FIGS. 18 and 19, the death cushion 90A having the lighting main body 63 supported by the edge of the top plate 80 of the desk will be described. FIG. 19 is a front view of the Death Cushion 90A. The cushion 70A is modeled after a bear. In addition, the modeling of the cushion 70A can be modeled on a pet animal such as a cat or a dog, or the bear or the like, which is not generally a pet animal but can cause attachment similar to a pet animal. The bear cushion 70A has a bear head 71, a bear neck 72, a bear hand 73, a bear foot 74, a bear upper back 75, and a lighting body 63, and has a death cushion body 1F. It is constructed with a space that can be wrapped inside it.
The death cushion 90A wraps the jaw receiving portion 22, the strut shaft 21, and the holding portion 30 of the death cushion main body 1F inside. The upper part of the jaw receiving part 22 and the support shaft 21 is on the bear's head 71 and the bear's neck 72, and the lower part of the support shaft 21 and the pair of extension holding members 32 are on the bear's shoulder and the upper part of the bear's back. From 75 to the abdomen, the base 40 is wrapped in the bear's hand 73, and the pressure contact portion 50 is wrapped in the bear's foot 74. The worker P adjusts the strut shaft 21 to a height suitable for the position of his / her jaw, and then wraps the jaw receiving portion 22, the strut shaft 21, the holding portion 30, and the like with the cushion 70A. The bear neck 72 has a stretchable portion such as a so-called slack so that the bear's head 71 can move upward.
For example, using a cushion 70A having a notch having a fastener extending from the bear's head 71 to the bear's foot 74 near the center in the left-right direction on the rear surface side of the cushion 70A, the worker P can use the cushion 70A from the notch to the death cushion main body 1F. Can be wrapped around. Since the lighting main body 63 is provided on the front surface of the death cushion main body 1F, the lighting main body 63 is provided on the front surface of the death cushion 90A. The lighting body 63 may be hung on the neck 72 of the bear or the like with an appropriate string or the like instead of the death cushion body 1F.

Based on FIGS. 20 to 22, it will be described that the death cushion 90A has an action of making the worker P unconsciously notice that he / she is in a forward leaning posture and urging the worker P to correct the forward leaning posture. .. The state in which the worker P is working on the desk using the death cushion 90A is as shown in FIG. 20, for example. That is, the worker P puts his chin on the top of the bear's head 71a, puts the base of the neck on the back side of the bear's head 71, and the chest on the upper back 75 of the bear, and puts both hands on the heaven of the desk. Stretch it on the board 80 and work toward a personal computer, for example. Even if the posture of the worker P is like this at the beginning of the work, as the work time elapses, the eyesight etc. deteriorates as the work time elapses, and the momentum is unconscious when trying to see the screen of the personal computer. In the meantime, he leans forward and wins. In such a case, the chest of the worker P pushes the cushion 70A near the virtual line N, so that the worker P exerts a force on the death cushion 90A to the front. Further, the base of the neck of the worker P also pushes the cushion 70A. Depending on the shape of the cushion, there may be variations in the position where the worker P pushes the cushion, but considering the burden on the body of the worker P, the chest of the worker P should be given priority to push the cushion. Is preferable.
Therefore, the operation will be described below. The force exerted by the worker P on the death cushion 90A is a force acting on the death cushion main body 1F via the cushion 70A. The action is the same as the action on the death cushion main body 1 (FIG. 1) when the worker P uses the death cushion 90 (FIG. 16). Therefore, in the following description of the action, the death cushion main body 1 This is done based on (Fig. 1).

FIG. 21 is an explanatory diagram of a state such as a force acting on the death cushion main body 1 (FIG. 1) supported by the top plate 80 of the desk when the posture of the worker P is not the forward leaning posture. A force F1 acts on the jaw receiving portion 22 in the vertical direction from the jaw of the worker P. If the posture of the worker P is not a forward leaning posture, the force F2 acting on the death cushion main body 1 (FIG. 1) from the worker P toward the front in the vicinity of the virtual line N is very small. The force F1 acts on the edge of the desk top plate 80 in the vertical direction, and balances with the force RF1 due to the reaction. On the other hand, the force RF2 is generated toward the rear surface by the moment due to F2, but since the force F2 is very small, the upper portion 100, which is the portion above the top surface 81 of the desk, is relative to the vertical line V at the edge of the desk. Therefore, the lower portion 110, which is a portion below the top surface 81 of the desk, hardly tilts backward with respect to the vertical line V. If so, the force RF2 causes the worker P to hardly sense the action of the force on the abdomen.
However, as shown in FIG. 22, as the forward leaning posture of the worker P increases, the force AF2 acting on the death cushion main body 1 (FIG. 1) from the worker P toward the front surface increases. Along with this, the degree to which the upper portion 100 tilts forward with respect to the vertical line V increases, a force F3 is generated at the point of action 42a, and the degree to which the lower portion 110 tilts backward with respect to the vertical line V also increases. That is, the change width X is generated. Then, the worker P notices that he / she is in a forward leaning posture by sensing the action from the force RAF2 that has increased corresponding to the change width X in the abdomen. In that case, the worker P who claims that the forward leaning posture is not a good posture can correct the forward leaning posture.

(Example)
Three volunteer subjects gave their impressions of using the Death Cushion 90 (Fig. 17) supported by the edge of the desk top plate 80 (the upper end of the desk top plate 80). A: Jaw and chest, etc. The effects related to supporting (maintaining the correct posture) and B: the effects related to lighting are summarized.
Subject 1
Situation before use: When working on a desk for a long time, it became a burden to support the weight of the head with the neck and shoulders, and stiff shoulders and headaches were likely to occur. When I was working on the desk for a long time, I had a bad posture because I was stooped or sat deep in a chair and leaned against the backrest. I work at my desk only with fluorescent lights in the room, such as at night, but it was hard to see because my body was in the shadow.
A: When I put my chin on the Death Cushion 90, I felt that the strength of my neck and shoulders was naturally relaxed. Since the height can be adjusted according to my sitting height, I was able to maintain a good posture even during long hours of desk work.
B: It was very easy to see because the lighting was coming out from my own eyes, so even the small work did not become a shadow.
Subject 2
Situation before use: When I worked on the desk for a long time, I leaned against the back of the chair, but before I knew it, I was leaning forward again. When I was working on the desk for a long time, I got stooped, or I sat deep in a chair and leaned against the backrest, and my posture got worse. I use a lighting stand on the desk opposite to myself, and when I stand up and read a book, the book is easy to read, but it is difficult to see because of shadows.
A: Most of the desk work is done by leaning forward, but it became easier because it supported the leaning forward. By putting the chest from the abdomen to the death cushion, I was able to naturally be aware of my posture.
B: When I read a book on my desk, I stand up and read it, but it was very easy to read because it was illuminated from my direction.
Subject 3
Situation before use: When I worked on the desk for a long time, I got sick by putting my elbows on the desk and putting on my cheeks. Looking directly at a lighting fixture (fluorescent lamp, etc.) could make your eyes worse.
A: It supports my head without having to wear a cheek stick, so I can work for a long time. I got sick by putting on my cheeks, but I was able to keep my posture with the Death Cushion 90.
B: Since lighting equipment (fluorescent lamps, etc.) did not enter my eyes, I did not look directly at it and it was kind to my eyes.
From the above results, it was confirmed that the Death Cushion 90 has an effect of encouraging the subject in the forward leaning posture to notice it and maintain the correct posture, and an effect of making the subject very easy to see the object to be worked on. Even if the desk work is performed in a forward leaning posture as in subject 2, the death cushion 90 has the effect that the forward leaning posture is supported and eased while being naturally aware of one's posture. was there.

According to this embodiment, (1) a strut portion 20 having a strut shaft 21 and a jaw receiving portion 22 at the upper ends of the strut shaft 21, and a holding portion 30 in which the strut shaft 21 is arranged inside to hold the cushion 70. In the death cushion main body 1 provided with the base portion 40 for supporting the holding portion 30, the strut shaft 21 has a first positioning means for determining the vertical position of the jaw receiving portion 22, and has a predetermined shape by the holding member. The holding portion 30 formed in has a second positioning means on the axis M of the support column shaft 21 corresponding to the first positioning means, and the base portion 40 is attached to the upper end portion of the top plate 80 of the desk. The base portion 40 is connected to the holding portion 30 from near the center to below the center in the vertical direction of the holding portion 30 so as to be supported, and extends substantially perpendicular to the axis M of the column shaft 21 toward the front surface. The material of the support portion 20, the holding portion 30, and the base portion 40 is metal such as iron or reinforced plastic, and the desk work is performed on the desk. As the forward leaning posture of the worker P with respect to the desk on which his / her jaw is placed on the receiving portion 22 becomes large, the support portion 20 and the holding portion 30 above the upper surface of the top plate of the desk (top surface 81 of the desk). Based on the point of action 42a in which the upper portion 100 along the axis M composed of the holding portion 30 of the above is in contact with the upper surface of the top plate of the desk (top surface 81 of the desk) at the tip portion of the base portion 40. When tilting forward with respect to the vertical line V at the edge of the desk while maintaining it along M and being substantially perpendicular to the base 40, the upper surface of the top plate of the desk (of the desk) in the holding portion 30 The lower portion 110 along the axis M formed by the holding portion below the top surface 81) is maintained along the axis M and substantially perpendicular to the base portion 40 with respect to the vertical line V. As the degree of backward tilt increases, the worker P senses the action of the force due to the lower portion 110 on the abdomen, the worker P is not in the forward leaning posture, and the lower portion 110 tilts backward with respect to the vertical line V. The death cushion body 1 is characterized in that it hardly senses the action of force on the abdomen when there is almost nothing to do.
Therefore, when the jaw of the worker P is placed on the chin receiving portion 22, the worker P is in a forward leaning posture, and the upper portion 100 is pushed to the front by the worker's chest or the like, the upper portion 100 is the edge portion of the desk.
