  In the joinery of Patent Document 1, the design property is improved by covering the other heel with one heel, but there is a problem that the user is difficult to open and close the shoji. That is, by shielding the other eyelid with the one eyelid, it becomes difficult for the user to grip the shielded side eyelid. Therefore, the conventional joinery has the subject that designability and opening / closing operability cannot be made compatible.

  This invention is made | formed in view of the said subject, The objective is to provide the fitting which can improve the designability, ensuring the opening / closing operativity of a shoji.

  A joinery according to one aspect of the present invention is for opening and closing an opening formed in a wall surface of a building. The joinery includes a first sliding member including a first face member disposed in the opening, a first rod attached to a peripheral edge of the first face member, and the first face member in the opening. A second shoji that includes a second face material arranged side by side, and a second saddle attached to the periphery of the second face material, a first vertical frame portion of the first saddle, and a second saddle Between the butted state in which the second vertical frame portion is abutted with each other and the separated state in which the first vertical frame portion and the second vertical frame portion are separated from each other, the first shoji and the second shoji And a support mechanism for supporting the first and second shojis so that at least the second shoji can move along the wall surface. The first vertical frame portion is attached to a vertical edge of the first face material on the second face material side, a first main body portion that is abutted against the second vertical frame portion, and the first vertical frame portion, It is located on the first face material side with respect to the butting line with the second vertical frame part, and protrudes from the first main body part on the side away from the first face material in the thickness direction perpendicular to the first face material. And the second vertical frame from the support in the moving direction of the first and second shojis so as to shield the second vertical frame when viewed from the thickness direction in the butted state. And a shielding part extending to the part side. A gap having a size capable of inserting a finger is formed between the distal end portion of the shielding portion and the second vertical frame portion. The front end portion of the shielding portion is folded in a curved shape toward the space between the shielding portion and the second vertical frame portion.

  According to this joinery, the second vertical frame portion can be shielded by the shielding portion of the first vertical frame portion in the abutted state of the first vertical frame portion and the second vertical frame portion.

Thereby, the user can insert the finger deeper in the moving direction (up to the first face material side).

  In the joinery, the third wall portion and the fourth wall portion may be arranged so as to face the second face material side, and may be connected via a curved surface portion.

  According to this configuration, since the curved surface portion exists between the third wall portion and the fourth wall portion extending in different directions, when the user performs the opening / closing operation of the first shoji or the second shoji, Even when the finger hits the connecting portion between the wall portion and the fourth wall portion, the pain of the finger can be reduced.

  In the fitting, the second vertical frame portion is attached to a vertical edge of the second face material on the first face material side, and a second main body portion that is butted against the first vertical frame portion, and the thickness direction. And a finger hook portion rising from the second main body portion on the side away from the second face material. The gap in the thickness direction between the front end portion of the shielding portion and the finger hanging portion may be larger than the gap in the moving direction between the finger hanging portion and the fifth wall portion.

  According to this configuration, the user inserts his / her finger in an oblique direction in the gap between the front end portion of the shielding portion and the finger-hanging portion so that the user can insert the finger beyond the finger-hanging portion to the back side (fifth wall portion side). can do. For this reason, in the opening / closing operation of the second shoji, the user can easily put his finger on the finger rest.

  In the joinery, the tip of the shielding portion includes a first plane extending in the moving direction, a second plane extending in the thickness direction, and a curved surface connecting the first plane and the second plane. May be included.

  According to this configuration, when the first shoji is movable, the pain of the finger can be reduced when the user performs the opening operation of the first shoji by holding the tip of the shielding portion.
