  2. Description of the Related Art Conventionally, as a sliding door finger pinching prevention tool, a protector 30 (corresponding to a stopper in the present invention) which is simply attached to a pull handle has been proposed as disclosed in Japanese Patent No. 4246137. In this conventional example, in order to use the protector main body 30B, the finger is pushed into the finger rest 30f1 below the pivotal support portion 42 of the protector main body 30B (the portion opposite to the protruding side) while swinging by pushing the finger rest. In order to make it into the stowed state, the lower surface of the protector body 30B is pushed up to bring it into a vertical state.

Japanese Patent No. 4246137

  In the conventional example, as shown in FIG. 4, the protector body 30 </ b> B is held in a vertical state (stored state) with the small concave portion 44 </ b> R engaged with the small protrusion 44 </ b> P of the handle 10. However, if the engaging force is increased, a large force is required when the protector body 30B is rotated to shift between the vertical state (stored state) and the horizontal state (use state), and the operability is deteriorated. If the force to be combined is reduced, when the protector body 30B is in the vertical state (stored state) and the sliding door 50 is opened with force, the protector body 30B held in the vertical state (stored state) is rotated forward by the impact. If this happens, when the tip of the protector main body 30B comes into contact with the adjacent overlapping wall or the surface of the sliding door, and the sliding door 50 is to be closed in this state, the protector Or broken body 30B, there is a problem that or damage the wall or sliding door overlap adjacent to each other. Further, if the protector main body 30B is rotated many times, there is a problem that the engaging portion is naturally worn and the engaging force is reduced.

  Further, as shown in FIG. 5, a portion of the protector body 30B opposite to the protruding side of the pivotal support portion 42 is a finger pad 30f1 serving as an operation portion for setting the storage state to the use state. 10, the protector main body 30B protrudes forward and enters the use state. Therefore, the protector main body 30B protrudes from the rear portion of the puller 10 in the use state. However, there is a problem that it may not be attached to a thin sliding door.

  According to the present invention, the stopper (corresponding to the protector body 30B of the conventional example) can be reliably maintained in the stored state even if the sliding door is opened vigorously without impairing the operability, and the thickness is reduced. It is an object of the present invention to provide a sliding door finger pinching prevention tool that can be used.

In order to solve the above-mentioned problems, the present invention provides a sliding door finger pinching prevention tool attached to a sliding door that is opened and closed by a pulling handle, wherein a stopper is attached to the lower portion of the pulling handle or the case so as to be slidable and rotatable by a shaft. The stopper is configured so that it can be changed to a storage state that is substantially perpendicular to the use state protruding from the handle or the case surface, and the stopper is provided with an operating portion in the upper part in the storage state and a shaft through which the shaft is inserted in the lower part. The shaft hole has a shape in which a lower substantially circular rotation hole and an upper non-circular locking hole are continuously provided, and the shaft has a non-circular cross section. When the stopper is in the stowed state, the shaft engages with the locking hole of the shaft hole, and the stopper cannot be rotated, and when the stopper is slid upward from the stowed state, the shaft disengages from the locking hole. The stopper can be turned Configured to, stopper, and rotates forward to slide from the retracted state to the upward by the operation unit, is brought into contact with its base at the bottom of the opening of the pull tab or case, from the pull or case surface In addition to being changed to the protruding use state, the operation unit is configured to be able to change to a substantially vertical storage state by rotating backward from the use state and sliding downward. It is a finger pinching prevention tool for sliding doors.

  The present invention is configured so that the stopper can be changed to a use state protruding from the surface of the handle or the case by an operation of sliding the stopper upward from the housed state and then rotating forward, thereby impairing the operability. Even if the sliding door is opened without force, the stopper can reliably maintain the storage state, does not easily rotate from the storage state, the stopper breaks, or the adjacent overlapping wall or sliding door can be removed. There is an effect that it is not hurt.

  In addition, the stopper can be slid upward from the stored state by the operation unit provided at the upper part in the stored state and turned forward so that the portion behind the shaft hole of the stopper can be moved backward. Since it is not necessary to make it protrude largely, the whole thickness can be made thin and there is also an effect that it can be attached to a thin sliding door.

  The stopper 7 is attached to the handle 1 so as to be slidable and rotatable about a shaft 8. The handle 1 includes a handle body 2 and a cover plate 3, and is integrated with screws 12 and 13. ing.

  The pulling body 2 has an upright portion 17 erected along the periphery of the opening back surface of the vertical rectangular surface plate 16. The upright portion 17 is provided with bearing holes 18 and 18 having substantially oval through holes so as to face the lower side plate.

  The stopper 7 is vertically long in the stowed state in the vertical state, and is provided with a shaft hole 19 penetrating in the left-right direction in the lower part and an operation part 22 protruding to the front side of the upper end part. The shaft hole 19 has a shape in which a lower circular rotation hole 20 and an upper oval locking hole 21 are continuously provided.

  The shaft 8 is provided with a circular flange 26 at one end of a rod-shaped portion 25 having a substantially oval cross section, and a portion of the rod-shaped portion 25 is engaged with the locking hole 21 of the shaft hole 19. The stopper 7 is non-rotatable and is in a vertical state (see FIGS. 3 and 6). A part of the rod-like portion 25 is disengaged from the locking hole 21 of the shaft hole 19, and the rod-like portion of the shaft 8 is formed in the rotation hole 20. In a state where the entire portion 25 is located, the stopper 7 is in a rotatable state (see FIGS. 7 and 8).

  Then, the stopper 7 is inserted into the lower part of the pull handle 1, and the shaft 8 is inserted into the one bearing hole 18, the shaft hole 19 and the other bearing hole 18 from the opposite side of the flange portion 26, and the end portion is connected to the E ring 9. stop. Accordingly, the stopper 7 is slidably and rotatably attached to the pull handle 1.

  The pull handle 4 on the opposite side of the pull handle 1 to which the stopper 7 is attached is composed of the pull handle main body 5 and the cover plate 6 in the same manner as the pull handle 1 and is integrated by screws 14 and 15. In FIG. 5, mounting legs 23 and 24 are provided on the upper and lower portions, and the stopper 7 is not mounted. From the front and back surfaces of the sliding door T, the handle 1 and the handle 4 to which the stopper 7 is attached are disposed, and the mounting screws 10 and 11 are screwed onto the mounting legs 23 and 24 of the handle 4 from the side of the pulling handle 1 and attached.

The operation will be described.
When the stopper 7 is in a vertical state and a part of the rod-like portion 25 of the shaft 8 is engaged with the locking hole 21 of the shaft hole 19 (see FIGS. 3 and 6), the sliding door T is fully opened. It can be completely overlapped with the adjacent wall K, but it is convenient when you want to widen the opening, such as when carrying a large load.

  From this state, when the stopper 7 is slid upward with the operation portion 22, the rod-like portion 25 of the shaft 8 is disengaged from the locking hole 21 of the shaft hole 19, and the whole is located in the rotation hole 20 and can be rotated forward. (See FIG. 7). When the stopper 7 is further rotated forward from this state, the base of the stopper 7 comes into contact with the lower opening of the handle 1 so that the stopper 7 is slightly inclined downward and protrudes from the handle 1 (see FIG. 8). It becomes. This state is a normal use state. When the sliding door T is opened, the protruding side surface of the stopper 7 abuts on the side surface of the adjacent wall K, and the sliding door T does not completely open and does not overlap the adjacent wall K. The fingers placed on the handle 1 are not pinched.

  When the stopper 7 is rotated backward and slid downward from the use state, the stopper 7 is stored in a state where a part of the rod-like portion 25 of the shaft 8 is engaged with the locking hole 21 of the shaft hole 19 in the vertical state. It will be in a state (refer to Drawing 3 and Drawing 6).

  In addition, the finger pinching prevention tool for the sliding door according to the present invention is not used as the handle 1 by attaching the stopper 7 to the handle 1 as in this embodiment. You may make it attach the stopper 7 to a case.
