Description

  The present invention relates to a suction cup type door handle used when opening and closing a sliding door or a hinged door.

  Sliding doors made of aluminum sashes are provided on the verandas and windows of condominiums and single-family homes, but generally these doors are not equipped with door knobs. For this reason, when a resident opens and closes a sliding door, he / she can put his / her finger on the vertical frame of the sliding door or press the palm against the glass surface of the sliding door to transfer the hand force to the sliding door. Yes.

  However, the method of transmitting force to the sliding door by placing a finger on the vertical frame or pressing the palm of the glass on the glass surface often does not properly transmit the force to the sliding door, making it difficult to open and close the sliding door. There is a case.

  In order to cope with such a problem, a suction cup type door knob has been proposed (for example, see Patent Document 1). The suction cup type door knob is composed of a suction cup that can be adsorbed on a surface to be attached and a knob for rotation provided on the opposite side of the suction face of the suction cup.

  If the door knob of patent document 1 is used, a door knob can be easily attached to a sliding door by making a suction cup adsorb | suck to the to-be-attached surface of a sliding door. Moreover, since the door knob is fixed by the suction force of the suction cup, it can be easily detached from the sliding door.

<Installation operation>
Next, with reference to FIG. 6 and FIG. 7, the operation | movement at the time of attaching the door handle 1 to the non-attachment surface of an opening / closing member is demonstrated. 6A to 6C show a state in which a part of the inner peripheral surface of the cylindrical portion 21 of the knob 20 and the cylindrical portion 31 of the cam member 30 (about 1/2 of the circumference) is developed on a plane. Moreover, Fig.7 (a), (b) shows the state before the attaching part 2a is attached to a to-be-attached surface, and the state after being attached.

  When attaching the door handle 1 to the non-mounting surface of the glass door as an opening / closing member, the suction cups 11 of the mounting portions 2a and 2b are pressed against the non-mounting surface 5 of the glass door 4 as shown in FIG. The air between the suction cup 11 and the non-mounting surface 5 is removed. Thereafter, the knobs 20 of the attachment portions 2a and 2b are rotated clockwise.

  As shown in FIGS. 6A to 6C, the protrusion 24 provided on the bottom 22 of the cam member 20 and the cam surface 34 of the knob 30 are always in contact with each other. On the cam surface 34, a convex portion 341, an inclined portion 342, and a concave portion 343 are formed.

  FIG. 6A shows a state before the knob 20 is turned. The protrusion 24 is in contact with the convex portion 341 of the cam surface 34, that is, the lowest portion of the inclined portion 342. In this state, as shown in FIG. 7A, the suction surface 12 of the suction cup 11 is in contact with the mounted surface 5 of the glass door 4 in a flat state.

  Next, as shown in FIG. 6B, when the knob 20 is manually rotated in the direction indicated by the arrow (clockwise), the protrusion 24 moves upward along the inclined surface of the inclined portion 342, and accordingly. The knob 20 also moves upward (in a direction away from the glass door 4).

  As described above, the tip of the locking portion 26 provided on the inner peripheral side of the knob 20 is sandwiched between the suction cup 11 and the ring-shaped locking portion 18 provided on the cylindrical portion 13 (see FIG. 2). ), The knob 20 and the cylindrical portion 13 move together in the central axis X direction. On the other hand, the peripheral part of the suction cup 11 is pressed in the direction of the glass door 4 by the tip part of the cam member 30. Further, the suction cup 11 is prevented from being pulled and shifted by the flange 14 in the central direction.

  As described above, since the peripheral portion of the suction cup 11 is made of a softer material than the central portion, when the knob 20 is turned clockwise, the peripheral portion of the suction cup 11 extends and the central portion extends from the glass door 4. It moves in the direction of leaving, and a gap is formed between the suction surface of the suction cup 11 and that portion is in a negative pressure state.

  When the knob 20 is turned from the state shown in FIG. 6B to the state shown in FIG. 6C, the protrusion 24 is fitted into the concave portion 343 of the cam surface 34 and is held in that state. Further, the tip of the protrusion 341 of the cam surface 34 abuts on the protrusion 25. FIG. 7B shows a front view of the mounting portion 2a in this state. In this state, as shown by a broken line, the gap between the suction surface 12 of the suction cup 11 and the glass door 4 is maximized, and the suction cup 11 is strongly pressed against the glass door 4 by atmospheric pressure.

  The other attachment portion 2b of the door handle 1 is also attached to the glass door 4 by the same operation. In this state, since the attachment portions 2a and 2b are strongly pressed against the glass door 4 by atmospheric pressure, the attachment portions 2a and 2b can be moved to the glass door even if the grip portion 3 is gripped by a human hand and pulled with a considerable force. Can not be peeled off from 4. In this way, the door handle 1 realizes the same function as a fixed door handle attached to a sliding door or the like, and the door handle 1 can open and close the sliding door or the like.

  On the other hand, when removing the door handle 1 from the glass door 4, if the knob 20 of the mounting portions 2 a and 2 b is turned counterclockwise, the protrusion 24 of the knob 20 is detached from the recess 343 of the cam surface 34. The mounting portions 2a and 2b are reversed from the state shown in FIGS. 6A to 6C to return to the state shown in FIG. 7A, and are in a negative pressure state formed between the suction cup 11 and the glass door 4. Is resolved. As a result, the suction cup 11 can be easily removed from the glass door 4.

  As described above, if the suction cup type door handle of the present invention is used, the attachment portion can be attached to or detached from the attachment surface by a simple operation of turning the knob. Further, the suction cup type door handle of the present invention has a rotating knob arranged between the suction cup and the gripping part, and the gripping part is directly connected to the suction cup. Operability can be realized.

  In the above-described embodiment, the knob 20 and the cylindrical portion 13 can be moved together in the axial direction by sandwiching the locking portion 26 of the knob 20 between the suction cup 11 and the locking portion 18. However, the movement in the axial direction may be realized by other configurations.

  The suction cup type door handle of the present invention can be used not only to open and close sliding doors and hinged doors, but also to open and close refrigerators and storages, and its application range is wide.
