JP 2002-119355 A

  By the way, in a chair provided with the operation member as described above, in order to provide a sense of unity and improve the aesthetics, a member smoothly connected to the operation member in appearance is provided adjacent to the operation member, or operability is improved. In some cases, an operation member may be disposed adjacent to each other. That is, in a chair provided with an operation member, another member (adjacent member) may be provided adjacent to the operation member. Thus, when moving so as to change the posture of the operation member provided with the adjacent member, a gap may be generated between the operation member and the adjacent member. When the user of the chair inserts a finger into the gap, the finger of the user is pinched between the operation member and the adjacent member when the posture of the operation member returns to the original posture. Usually, the urging force for returning the operation member to the original posture is set to be weak, and it is designed so that the user does not hurt the finger. However, if the finger is pinched between the operation member and the adjacent member, the user feels uncomfortable.

  In addition, such a problem is not restricted to a chair, For example, it arises in general furniture provided with the operation member by which attitude | positions, such as a desk which can adjust the height of a top, are changed.

  The present invention has been made in view of the above-described problems, and in furniture including an operation member whose posture is changed, a user's gap is provided between an operation member and an adjacent member disposed adjacent to the operation member. An object of the present invention is to prevent a user from feeling uncomfortable by pinching a finger.

  The present invention adopts the following configuration as means for solving the above-mentioned problems.

  A first invention is furniture including an operation member which is changed from a steady posture to an operation posture by an operation of a user, and an adjacent member disposed adjacent to the operation member, the furniture including the operation member or the adjacent A configuration is adopted in which a shielding portion is provided which is provided on the member and which closes a gap generated by the operation member and the adjacent member when the operation member is in the operation posture.

  According to the present invention, when the operating member is in the operating posture, the gap generated by the operating member and the adjacent member is closed by the shielding portion. Therefore, the user's finger can be prevented from being pinched between the operation member and the adjacent member, and the user can be prevented from feeling uncomfortable.

  According to a second aspect, in the first aspect, the operating member is formed in a horizontal shape extending in a horizontal direction and a plate shape whose front and back surfaces are directed upward and downward, and the distal end side is raised about the central axis. And the adjacent member is provided with a flange that is arranged at the same height as the operation plate in the operation member in the steady posture and that has a front and back surfaces that are directed upward and downward. Is adopted.

  According to the present invention, since the operation plate included in the operation member and the flange of the adjacent member are arranged side by side at the same height when the operation member is in the steady posture, a sense of unity between the operation member and the adjacent member is obtained. It becomes more beautiful and aesthetic. On the other hand, since the position of the operation member is changed by moving the tip of the operation plate up and down, a gap is easily generated between the operation plate and the flange. On the other hand, since the present invention includes the above-described shielding portion, it is possible to prevent the user's finger from being sandwiched between the operation member and the adjacent member even in such a furniture excellent in unity. It is possible to prevent the user from feeling uncomfortable.

  In a third invention according to the second invention, the shielding portion protrudes downward from an edge of the operation plate on the flange side, and directs front and back surfaces in a direction in which the operation member and the adjacent member are arranged. Adopt a configuration consisting of shielding pieces.

  According to the present invention, since it can be provided integrally with the operation plate, it is possible to provide a shielding part without increasing the number of parts. Furthermore, when the operation plate is viewed from above, the shielding piece is less noticeable in appearance, and the shielding piece does not impair the beauty.

  According to a fourth aspect of the present invention, in the third aspect of the present invention, the shield piece has an inclined side that goes downward from the back side to the tip side of the operation plate.

  For example, in the case where the operation plate is disposed at a position where it is difficult for the user to see, the possibility of the user's fingertips hanging on the root of the operation plate is increased. Since the base of the operation plate is close to the pivot, it is necessary to operate the operation plate with a very strong force when changing the posture of the operation plate with the fingertip on the base of the operation plate. On the other hand, the operability may give a bad impression. On the other hand, according to the present invention, the shielding piece has an inclined side that goes downward as it goes from the back side to the tip side of the operation plate. For this reason, when a large force is applied to the back side (that is, the base side) of the operation plate, the user's fingertip moves toward the distal end side of the operation plate along the inclined side of the shielding piece provided at the edge of the operation plate. It becomes easy to move, and the user's fingertip can be guided to the front end side of the operation plate which is easy to operate without being conscious of the user. Therefore, according to the present invention, the operation member can be operated with a weak force, and the operability is excellent.

  According to a fifth invention, in any one of the second to fourth inventions, the operation member includes a connection portion connecting the operation plate and the pivot, and a protrusion provided on the lower surface of the connection portion. Adopt the configuration.

  According to the present invention, since the connection portion is provided, the operation plate can be provided further away from the pivot, and the operation of the operation plate can be performed with a weaker force. Furthermore, the protrusion part is provided in the lower surface of the connection part. For this reason, even when the operation plate is disposed at a position that is difficult for the user to see, the protruding portion interferes with the user's fingertip hanging on the lower surface of the connecting portion close to the pivot. And the user's fingertip can be guided to the front end side of the operation plate that is easier to operate.

  According to a sixth invention, in any one of the second to fifth inventions, the second invention includes a lever that is moved along the upper surface of the flange, and is rotatable by a user moving the lever. A configuration in which the operation member is provided is adopted.

  According to the present invention, since the operation member and the second operation member can be provided close to each other, the operability is excellent. Furthermore, according to the present invention, it is possible to prevent the finger of the user from being pinched between the operation member and the adjacent member in the furniture excellent in such operability.

  7th invention is a chair provided with the operation member provided in the side part or lower part of a seat, and the adjoining member arrange | positioned adjacent to the said operation member, Comprising: In any one of said 1st-6th invention. Adopt a configuration that consists of a certain furniture.

  According to the present invention, it is possible to prevent the user's finger from being pinched between the operation member and the adjacent member, and to provide a chair that does not give the user a sense of discomfort.

  According to the present invention, when the operating member is in the operating posture, a gap generated between the operating member and the adjacent member is closed by the shielding portion, and the user's finger is prevented from being sandwiched between the operating member and the adjacent member. It is possible to prevent the user from feeling uncomfortable.
