Description

  The present invention relates to a handle provided at an end portion of a sliding door and the like and a sliding door provided with the handle.

  Conventionally, pulling doors for opening and closing sliding doors are attached to predetermined positions on both door surfaces of sliding doors provided at entrances of rooms, buildings, etc., such as bags and shoji screens. Generally, a pulling handle has a finger hanging concave portion on which a finger is hung and an attachment hook portion for fixing the finger hanging concave portion to a predetermined position on the door surface, which are integrally molded and perforated at a predetermined position on the door surface. It is designed to be fitted into the mounting recess (for example, Patent Document 1).

  However, when the handle is provided on the door surface as in the sliding door according to Patent Document 1, it is necessary not to completely retract the sliding door, but to provide a remnant that protrudes from the door pocket and serves as a clue. Therefore, the effective opening of the sliding door is narrowed by the amount left behind. In order to solve this, there has been proposed a pulling handle that allows a finger to be hooked even when the sliding door body is completely pulled into the door pocket (for example, Patent Documents 2 and 3).

  In the pull handle according to Patent Document 2, a recess into which a finger can be inserted from the end face side is formed on the end face of the sliding door main body so as to straddle one surface side of the sliding door main body. A locking portion is formed to be recessed in the thickness direction and to hook the finger inserted from the end face side.

  Further, a puller according to Patent Document 3 includes a substantially concave-shaped main body that is fitted in a concave portion provided in the mouth of a sliding door, and a pressing member provided in the main body, and a pressing plate and a handle plate that constitute the pressing member. When the handle plate of the holding member is pushed to the side opposite to the side where the hand is placed, the holding plate moves along the inner buttock that is the guide, and the handle plate also moves the hand. Since it moves on the side opposite to the hung side, a larger space is secured on the hung side.

  The pulling handle according to Patent Document 2 can pull out the sliding door in a state where it is completely drawn into the door pocket by inserting a finger from the end face side and hooking it to the locking portion, but it is operated because the clue is small. There was a problem that it was difficult. Moreover, when pulling out the sliding door fully retracted into the door pocket, there is a problem that it can be operated only from one side of the sliding door.

  Furthermore, in the pulling handle according to Patent Document 3, the tip portion of the pressing plate is formed in a T shape, and the tip portion of the T shape moves in the concave portion on the back side of the handle plate, so the moving range of the pressing plate is small. In particular, a thin sliding door has a problem that it is difficult to operate because the clue is small. In addition, since the clue is not a flat surface, there is a problem that the touch feeling is not good in the operation of pulling out the sliding door.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a pulling handle that can sufficiently take a clue when opening and closing the sliding door, and a sliding door provided with the pulling handle.

  Another object of the present invention is to provide a pulling door that can be easily pulled out from both sides of the sliding door even when the sliding door main body is completely pulled into the door pocket, and a sliding door provided with the pulling handle.

  Still another object of the present invention is to provide a handle having a good touch feeling and excellent operability and design, and a sliding door equipped with the handle.

  According to the present invention, the handle has an upper arm portion, a lower arm portion, and a connecting arm portion that connects the upper arm portion and the lower arm portion, and has a cross section (the center of the thickness of the sliding door to which the pull handle is attached). A cross-section cut by a line) is configured to have a U-shape having an open end, and a frame member fitted and fixed to a notch recess formed at the end of a sliding door, and an open end side Centering on the pivot shaft pivotally supported by the upper arm portion and the lower arm portion between the clue member provided between the upper arm portion and the lower arm portion and the connecting arm portion and the clue member of the frame member And a partition plate mounted on the frame member so as to be rotatable. The rotation shaft is located on the connecting arm portion side of the partition plate, and the partition plate gradually increases in thickness toward the opening end side of the frame member. It has a taper part.

  As described above, the pulling handle according to the present invention has a tapered portion in which the thickness gradually increases toward the opening end side of the frame member. The sliding door can be pulled out from both sides of the sliding door even when the sliding door body is completely pulled into the door pocket. Furthermore, when the sliding door is fully opened, even if the partition plate protrudes from the sliding door surface (door plate surface), the taper portion slides on the door pocket and rotates, so that the partition plate is moved from the protruding state to the original state. It can return to the state smoothly.

  The surface of the other end of the partition plate preferably has a convex arc-shaped cross section, and the surface on the partition plate side of the clue member preferably has a concave arc-shaped cross section corresponding to the convex arc-shaped cross section. Thereby, the clearance gap between a partition plate and a clue member is small, and it can prevent seeing through the other through the clearance gap of this handle from one side of a sliding door.

  It is also preferable that a stopper for limiting the rotation angle of the partition plate is provided on each of the lower surface of the upper arm portion and the upper surface of the lower arm portion of the frame member. Thereby, it can prevent that a partition plate rotates large and a clearance gap opens, and can prevent the problem that the other side of a sliding door can be seen.

  It is also preferable that the clue member has a thickness smaller than the door plate thickness of the sliding door, and that concave grooves are formed on both surfaces in the thickness direction. Thereby, even if the sliding door main body is completely pulled into the door pocket, both side surfaces of the pulling handle can be picked, and the drawer operation is facilitated.

  It is also preferable to further include a pair of U-shaped frames that are mounted from both side surfaces of the frame member and can be fitted into the notch recesses. As a result, the appearance of the handle becomes good, the design can be improved, and various door panel thicknesses can be accommodated.

  According to the present invention, by using the above-described pull handle of the present invention, the sliding door can be sufficiently taken from both sides of the sliding door without fear of pinching the finger, and the sliding door body is completely attached to the door pocket. Even in the retracted state, the drawer operation can be performed from both sides of the sliding door. Furthermore, a sliding door excellent in operability and design can be provided.

  According to the handle of the present invention, since the partition plate has a tapered portion whose thickness gradually increases toward the opening end side of the frame member, there is no risk of pinching a finger when opening and closing the sliding door, and the clue is from both sides. The sliding door can be taken out from both sides of the sliding door even when the sliding door body is completely pulled into the door pocket. Further, when the sliding door is fully opened, even if the partition plate protrudes from the sliding door surface, the tapered portion slides against the door pocket, so that the partition plate can smoothly return from the protruding state to the original state. .

  According to the sliding door of the present invention, by using the above-described pulling handle of the present invention, there is no fear of pinching fingers, the clues can be taken sufficiently from both sides of the sliding door, and the sliding door body is completely retracted into the door pocket.
