US Pat. No. 6,683,394 JP 2001-269377 A

  At present, a chair used in a waiting room of a public facility such as an airport lobby is desired to have a chair as described in Patent Document 2 in which the upper and lower bodies of a seated person can be placed comfortably on the seated body. Yes. Further, even in the case of such a type of chair, it is desirable that the power plug outlet is provided near the seating position.

However, in a chair of the type described in Patent Document 2, when the power plug insertion port is installed below the side of the seating area of the seating body, the sole of the seated person is placed on the floor when the power plug is detached. The occupant must bend down greatly forward and downward in an unstable state that does not reach the surface. For this reason, the power plug cannot be easily attached or detached.
In addition, in a chair of the type described in Patent Document 2, when the power plug outlet is installed below the side of the seating area of the seating body, the seated person relaxes on the seating body and deposits the body Since the insertion port of the power plug is located at a position where the line of sight is difficult to reach from the head of the head, it is disadvantageous also in terms of anti-theft.

  Therefore, the present invention provides a chair having an area for placing a leg of a seated person on the front and back of the seating area of the seating body and an area for supporting the back. Try to provide a chair.

In order to solve the above-described problems, the chair according to the present invention includes a support structure that stands on the floor, a seat on which a seat occupant is placed, and a seat that is positioned outward of the seat. And a side structure having an insertion port for a power plug, wherein the seating body is supported by the support structure and supports a seated person's buttocks on the upper surface side, and the seating area Extending from the front part of the upper part to the front upper side and supporting the above-knee part of the leg of the seated person on the upper surface side, and extending from the front part of the above-knee support area to the front lower part. A knee support region that supports the lower part of the leg of the seated person on the upper surface side, and a back support that extends from the rear part of the seating area toward the rear upper side and supports the back part of the seated person on the front side. It has a region, wherein the the receptacle is a side view, above the upper surface of the knee support area of the seating member , Yet, Oite behind a position of the boundary portion between the knee support region and the knee support area, are disposed facing the front side in front of the side structures, the upper surface of the side structure Is an article placement surface that is continuous in the front-rear direction.

  As a result, the seated person who put the body on the seating body can extend above the upper surface of the above-knee support area by extending the arm forward with the shoulder located near the back support area as the center, and It is possible to easily access the insertion port located behind the boundary between the upper support region and the lower knee support region. Therefore, the power plug of the power-utilizing device can be removed from the insertion port relatively easily. In addition, the insertion port is positioned near the upper part of the knee of the seated person placed on the above-knee support area, or near the waist of the seated person placed on the seat area. When a third party other than the seated person tries to touch the power plug attached to the insertion port, the third party can easily enter the line of sight of the seated person. Therefore, it is advantageous also in terms of anti-theft.

In this case, since the above-knee support area extends from the front part of the seating area toward the front upper side, the seated person can move his / her knee part from side to side relatively easily with the sitting posture. For this reason, the insertion port is arranged close to the position where the seated person's knee moves, which is a psychological burden when a malicious third party tries to approach the insertion port. Therefore, by adopting this structure, the anti-theft property can be further improved.

In this case, since the outlet of the power plug faces away from the upper body of the seated person, when the seated person is taking a nap on the seated body, the armtip or foot of the seated person is different. It becomes difficult to get close to the entrance.
Further, in this case, the upper surface of the side structure can be used for placing an article. At this time, even if water drops or the like may flow down from the article placed on the upper surface of the side structure, the power plug insertion port is provided in the side structure so that it is directed forward. Water droplets can be prevented from flowing into the mouth.

The side part structure may be formed to have a longitudinal length that reaches a side part of the back support region of the seating body in a side view.
In this case, it becomes difficult to create a space for an object or a part of the body to enter between the side structure and the back support region or the seating region of the seating body, which improves usability. In addition, since the side part of the side structure is interposed between the upper body of the seated person who has the upper body in the back support area and the power plug insertion port, the armtips and legs of the seated person You won't accidentally touch the vicinity of the outlet.

The front end portion of the article placement surface may be positioned in front of the insertion port.
In this case, even if water drops may drop from the article placement surface, the front end of the article placement surface is positioned in front of the insertion port, so that the water droplets enter the power plug insertion port. Direct inflow can be prevented.

  According to this invention, the insertion port of the power plug of the side structure is higher than the upper surface of the above-knee support region of the seating body in a side view, and the boundary between the above-knee support region and the below-knee support region. Since the seat is a chair having an area for placing the leg part of the seated person on the front and back of the seating area of the seating body and an area for supporting the back part, the seating person inserts the seat. The power plug can be easily attached to and detached from the battery, and it is advantageous in terms of anti-theft performance.

In this embodiment, the side structure 30 is supported by the seating body 20 by fastening the connection bracket 36 to the lower surface of the seating area A1 of the seating body 20, but the side structure 30 May be a structure connected to the support structure 10. Further, the side structure 30 may be directly supported on the floor surface.

  As described above, in the chair 1 according to this embodiment, the insertion port 34a of the power plug is above the upper surface of the above-knee support region A2 of the seating body 20 in a side view, and further above the above-knee support region. It arrange | positions in the position which becomes back rather than the boundary part P of A2 and lower knee support area | region A3. For this reason, a seated person who puts his / her body on the seating body 20 can easily access the power plug insertion port 34a by extending his / her arm forward with the shoulder located in the vicinity of the back support area A4 as the center. Can be accessed. That is, the seated person can easily remove the power plug of the power-use device to be used from the insertion port 34 a of the side structure 30 while keeping the posture in which the legs are stretched and seated on the chair 1.

Here, when the insertion port 34a is located at a more rear part, for example, in the vicinity of the front surface of the back support region A4 in the seating body 20, the seated person can move his wrist Work to move the arm locally or move the arm on the side opposite to the side where the insertion port 34a is arranged must be performed. Such a movement causes fatigue of the shoulders and arms of the seated person. However, in the case of the chair 1 according to this embodiment, the seating person stresses the arms and shoulders because the insertion port 34a is located at an appropriate front. You can move without.
In addition, when the insertion port 34a is located in front of a front part, for example, the boundary portion P between the above-knee support area A2 and the below-knee support area A3 in the seating body 20, the seated person's hand Is difficult to reach the insertion port 34a. Therefore, in this case, it is necessary to perform an operation in which the seated person gets down from the seating body 20 once or stands on the upper surface of the seating body 20 and moves forward. Such an operation is troublesome for the seated person and there is a risk of sliding off from the seating body 20.

  Further, particularly in this embodiment, the insertion port 34a is arranged at a position slightly above the upper surface near the rear part of the above-knee support region A2 of the seating body 20 in a side view. The power plug can be attached to and removed from the insertion port 34a very easily in a state where the plug is naturally extended forward.

Further, in the chair 1 according to this embodiment, the power plug insertion port 34a is located above the upper surface of the above-knee support region A2 of the seating body 20 in a side view, and further, above the above-knee support region A2 and below the knee. Since the insertion port 34a is disposed behind the boundary portion P with the support area A3, the insertion port 34a is located near the upper part of the knee of the seated person placed on the above-knee support area A2 or sitting. It will be located in the vicinity of the waist of the seated person placed on the area A1. For this reason, when a malicious third party tries to touch the power plug attached to the insertion port 34a, the third party can easily enter the eyes of the seated person. Therefore, in the case of the chair 1 according to this embodiment, it is advantageous also in terms of the anti-theft property.

  In the case of the chair 1 of this embodiment, the above-knee support region A2 of the seating body 20 extends so as to incline from the front part of the seating region A1 to the front upper side. The part can be moved from side to side relatively easily. For this reason, the insertion port 34a is arranged close to the position where the knee of the seated person moves, but a malicious third party approaches a portion where a person is likely to move. I don't like that. Therefore, by adopting this structure, the anti-theft property can be further improved.

  Further, in the chair 1 according to this embodiment, the power plug insertion port 34a is provided on the front surface of the side structure 30 so as to face the front side. It faces in the direction away from the head of the seated person. For this reason, when the seated person takes a nap on the seated body 20, the armtip and the leg of the seated person are unlikely to approach the insertion port 34a. For this reason, it is advantageous in terms of safety.

Moreover, in the chair 1 which concerns on this embodiment, the side part structure body 30 which has the insertion port 34a in the front surface is formed in the front-back length which reaches the side part of the back support area | region A4 of the seating body 20 by a side view. . For this reason, it is difficult to create a space for an object or part of the body to enter between the side structure 30 and the back surface support area A4 or the seat area A1 of the seat body 20. Therefore, when the chair 1 is used, the article does not fall on the floor surface, or a part of the body is caught, and the convenience of the seated person is improved.
Further, according to this structure, the side plate 37 portion of the side structure 30 is interposed between the upper body of the seated person who has the upper body in the back support area A4 and the insertion port 34a. It is possible to prevent a person's arm tip or foot from touching the vicinity of the insertion port 34a by mistake.

  Moreover, in the chair 1 which concerns on this embodiment, let the upper surface of the side part structure 30 arrange | positioned at the side part of the seating body 20 be the article mounting surface 32a which continues in the front-back direction. For this reason, the upper surface of the side structure 30 can be used as a table for placing articles or writing. In the case of the chair 1 according to this embodiment, since the insertion port 34a is provided on the front side of the side structure 30 and the upper surface is the article placement surface 32a, the beverage placed on the article placement surface 32a. Even if the water droplets flow down from the container or the like, it is possible to prevent the water droplets from flowing into the insertion port 34a.

  In particular, in the case of this embodiment, the top plate 32 of the side structure 30 is more forward than the front wall 33 so that the front end portion 32a-E of the article placement surface 32a is positioned in front of the insertion port 34a. Therefore, even when a water droplet may drop from the front end portion 32a-E of the article placement surface 32a, it is possible to prevent the water droplet from flowing directly into the insertion port 34a.

  In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary. For example, in the above-described embodiment, the insertion port 34a is provided in the front wall 33 of the side structure 30, but the insertion port 34a is formed in the above-knee support region A2 of the seating body 20 in a side view. The article placement surface 32a of the side plate 37 or the top plate 32 of the side structure 30 is located above the upper surface and at a position behind the boundary portion P between the above-knee support region A2 and the below-knee support region A3. You may make it provide on top.
