  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same or an equivalent part in several drawing.

  FIG. 3 is a partially cutaway exploded perspective view of the sliding door lock 1 according to the present embodiment. As shown in FIG. 3, the lock 1 for the sliding door is formed with a flat rectangular tube-shaped lock storage space 2b inside one end of the opening / closing tip 2a, which is the end of the sliding door 2, and the lock storage space 2b has a lock. The sickle lock 3 which is an example of a main body is accommodated.

  The sliding door 2 is formed with an indoor side handle 4 at an almost intermediate height on the opening side of the opening / closing front end 2 a and on the side surface on the indoor side, and on the outdoor side surface of the sliding door 2 on the opposite side of the indoor side handle 4. The outdoor handle 5 is formed. That is, the indoor and outer handles 4 and 5 are disposed on both sides of the lock storage space 2b.

  The sliding door 2 is arranged at the entrance of a required room or space such as an indoor toilet or a washroom, etc., slides on the sill to open and close the entrance and the like, and contacts the door frame 8 (see FIG. 5) when the door is closed. It has an open / close tip 2a.

  As shown in FIG. 3, the sliding door 2 has an opening 2 c communicating with the lock storage space 2 b at the end of the opening / closing tip 2 a, and a band-like sealing plate is formed in the opening 2 c. 2d is provided and closed. The sealing plate 2d is formed with an entrance / exit 2e through which a distal end portion of a sickle lock body 3a described later enters and exits and an entrance / exit port 2f through which the distal end portion of the trigger stopper 6 enters and exits.

  As shown in FIGS. 4 and 5, the sliding door 2 has a metal rectangular flat mounting base 2g attached to the side wall in the lock storage space 2b, and the sickle lock 3 is disposed on the mounting base 2g.

  The sickle lock 3 includes a hook-shaped sickle lock main body 3a and a sickle cam portion 3b integrally coupled to the sickle lock main body 3a. The sickle lock 3 has a sickle cam portion 3b rotatably attached to a mounting base 2g by a support shaft 3c. The sickle cam portion 3b has a notch 3d. A round bar-shaped operating shaft 3e is fitted in the notch 3d in an orthogonal direction with a little play, and the operating shaft 3e reciprocates in a direction perpendicular to the axis (vertical direction in the figure indicated by a white arrow in FIG. 4). Thus, the sickle lock body 3a reciprocates between the locking position shown in FIG. 5 and the unlocked (opened) locking position shown in FIG. Reference numeral 3f denotes a V-shaped torsion spring that elastically holds the sickle lock body 3a at the locked position and the unlocked position, respectively. The torsion spring 3f has a V-shaped corner portion formed of a coil spring, a pair of left and right V-shaped tip portions are formed in an annular shape, and one of the annular tip portions is a protrusion (not shown) of the mounting base 2g. ), And the other tip is rotatably fitted on the outer periphery of the protrusion protruding from the sickle cam portion 3b. Reference numeral 3g denotes a sickle stopper which is supported at the unlocking position of the sickle lock body 3a.

  The sickle lock 3 is provided with a round bar-shaped trigger stopper 6 in the lock storage space 2b. The trigger stopper 6 has a hemispherical tip portion (left end portion in the figure) protruding outward from the entrance / exit 2 f of the opening / closing tip 2 a of the sliding door 2. The trigger stopper 6 is configured to be able to appear and retract by elastically supporting a rear end portion thereof with a coil spring 6a.

  The trigger stopper 6 is formed with a fitting recess 6b in the middle portion in the axial direction for fitting, for example, the lower end portion of the dog-shaped stopper cam 7 in the figure. The upper end portion of the stopper cam 7 in the figure is detachably engaged with the locking recess 3h of the sickle cam portion 3b.

  For this reason, as shown in FIG. 5, when the sliding door 2 is closed and the open / close tip 2a contacts the door frame 8, the protruding end of the trigger stopper 6 is pushed into the lock storage space 2b by the door frame 8. I will be immersed. For this reason, the stopper cam 7 rotates by a required angle around the support shaft 7a, and the upper end portion of the stopper cam 7 in the figure is released from the engagement state with the locking recess 3h of the sickle cam portion 3b. Thereby, rotation of the sickle-lock main body 3a is attained.

  Therefore, as shown in FIG. 5, after the engagement between the sickle cam portion 3b and the trigger stopper 6 is released, when the operation shaft 3e moves to the upper locking position in the direction perpendicular to the axis, for example, the sickle lock body 3a. Rotates around the support shaft 3c, engages with a locking shaft 8a horizontally mounted on the vertical frame of the door frame 8, and is locked.

  As shown in FIG. 6, the operation shaft 3 e has the outdoor operation knob 9 and the indoor operation knob 10 attached and fixed to both ends in the axial direction. The outdoor operation knob 9 reciprocates between the lock position and the unlock position in the arrow direction (vertical direction) in the figure on the bottom surface 5a of the upper part of the vertically long bottomed rectangular tube-shaped outdoor handle 5 in the figure. It is configured to be slidable.

  Further, the indoor side operation knob 10 is capable of reciprocating between a locking position and an unlocking position in the arrow direction (vertical direction) in the figure on the bottom surface 4a of the vertically long bottomed rectangular tube-shaped indoor side handle 4 in the figure and slides. It is configured to be movable. That is, the indoor operation knob 10 and the outdoor operation knob 9 move up and down in conjunction with the vertical movement of the operating shaft 3e.

  As shown in FIG. 6, the indoor side puller 4 and the outdoor side puller 5 are respectively formed on the indoor side and the outdoor side of the sliding door 2, and are vertically long rectangular attachment openings 2h communicating with the lock storage space 2b (see FIG. 6). 3), each is fitted and attached to form a digging pull.

  Further, as shown in FIG. 7A, the indoor operation knob 10 has a rectangular planar shape made of a metal flat plate such as stainless steel, and its outer surface is formed by a substantially smooth surface, which is the upper limit position of reciprocation. In the locking position, an indoor gap ga into which, for example, one user's finger can be inserted is formed between the upper end surface in the figure of the indoor operation knob 10 and the inner surface of the indoor handle 4 in the figure. .

  On the other hand, as shown in FIG. 7 (b), the outdoor operation knob 9 is also formed into a rectangular planar shape by a flat plate made of metal such as stainless steel, and the outer surface thereof is formed of a substantially smooth surface. Between the upper end surface of the operation knob 9 in the drawing and the inner end of the upper end portion of the outdoor handle 5 in the drawing, a minute gap gb that is very narrower than the indoor gap ga is formed. The outdoor minute gap gb is a gap into which a flat body such as a coin c and a driver shank tip d shown in FIG.

  When the outdoor operation knob 9 is in the locking position, which is the upper limit position of the reciprocation, the required large display portion 11 such as red is exposed below the lower end of the outdoor operation knob 9 in the figure. The display unit 11 is formed on the bottom surface 5a of the outdoor handle 5 and when the outdoor operation knob 9 is in the unlocked position of the reciprocation lower limit position, it is shielded by the outdoor operation knob 9 and cannot be visually observed. The outdoor operation knob 9 is exposed and visible when it slides (moves) to the upper limit unlocking position. When the display unit 11 can be seen, for example, it indicates that the room such as a toilet is in use or full, and when it cannot be seen, it indicates an empty room or the like.

  The sliding door lock 1 is provided with a blocking mechanism for blocking the locking operation operated by the indoor operation knob 10 in the outdoor operation knob 9 and the outdoor handle 5 as necessary.

  That is, as shown in FIGS. 8A and 8B, the blocking mechanism is provided with the lock member 12 and the slider 12x on the lower and upper portions of the rear surface 9a of the outdoor operation knob 9, respectively, while the bottom surface of the outdoor handle 5 is provided. A locking plate 13 shown in FIG. 10 or the like is provided in the upper part of FIG.

  As shown in FIGS. 9A to 9C, the lock member 12 has a lock member main body 12a formed in a horizontally long rectangular shape by a required metal plate or the like. A small rectangular leaf spring portion 12b, which is an example of an elastic portion, is formed by notches formed on both sides in the width direction.

  As shown in FIGS. 9B and 9C, the leaf spring portion 12b is formed such that the lower end portion in the drawing protrudes toward the locking plate 13 from one surface of the lock member main body 12a.

  The lock member 12 has a pair of left and right projections 12c and 12d as an example of a locked portion protruding from the lock member main body 12a on both sides of the leaf spring portion 12b.

  As shown in FIG. 9C, these convex portions 12c and 12d protrude in the same direction as the protruding direction of the leaf spring portion 12b, but the protruding amount is smaller than the protruding amount of the leaf spring portion 12b. However, the protruding tips of the convex portions 12c and 12d are relatively more than the leaf spring portion 12b when the leaf spring portion 12b is greatly pressed toward the lock member main body 12a and elastically compressed as will be described later. Protrusively outward.

  The slider 12x has a slider body that is substantially the same shape and size as the lock member body 12a, but does not include the leaf spring portion 12b and the pair of convex portions 12c and 12d, and slides on the opposing surface of the locking plate 13. It is formed on a simple smooth surface.

  FIG. 10 is a front view of a locking plate 13 which is an example of a locking member. The locking plate 13 is fitted and fixed to the outer peripheral edge of the opening of the bottom surface 5 a of the outdoor handle 5 and is disposed opposite to the lock member 12.

  The locking plate 13 is formed with a vertically long insertion hole 13b in the drawing through which the operating shaft 3e penetrates in the thickness direction at a substantially central portion of a substantially rectangular flat plate-shaped locking plate body 13a. A pair of vertically long engagement holes 13c and 13d, which is an example of a locking portion, are formed on both the middle and left and right sides.

  The insertion hole 13b and the engagement holes 13c and 13d are formed in such a length that the operating shaft 3e can reciprocate between the locking position and the unlocking position in the direction perpendicular to the axis (vertical direction in FIG. 10).

  FIG. 11 shows the relative positional relationship between the locking plate 13 when the outdoor operation knob 9 is moved to the locking position and the pair of left and right projections 12c and 12d of the lock member 12 shown in FIG.

  That is, as shown in FIG. 1, when the outer surface of the outdoor operation knob 9 is pressed toward the indoor handle 4 side (left side in FIG. 1) by the user's finger or the like, the leaf spring portion 12b of the lock member 12 is locked. It is pressed to the 13th side and is crushed elastically. For this reason, the convex portions 12c and 12d of each lock member 12 protrude relatively larger toward the locking plate 13 than the leaf spring portion 12b. Accordingly, in FIG. 11, the pair of left and right protrusions 12 c and 12 d of the lower lock member 12 are locked to the lower end portions of the pair of left and right engagement holes 13 c and 13 d of the locking plate 13, and the outdoor operation knob 9. Is prevented from moving downward, i.e., to the unlocked position.

  On the other hand, as shown in FIG. 11, the upper end in the drawing of the operating shaft 3e is locked to the upper end in the drawing in the central insertion hole 13b of the locking plate 13, so that the indoor side operation knob 10 and the outdoor operation knob are As shown in FIG. 7B, a minute gap gb is formed between the upper end of the outdoor operation knob 9 and the upper end of the outdoor handle 5 in the drawing. The

  Next, the operation of the sliding door lock 1 will be described.

  First, when a user enters a required room such as a toilet and closes the sliding door 2, the head protruding outward from the trigger stopper 6 collides with the outer surface of the vertical end of the vertical frame of the door frame 8, as shown in FIG. Then, it is immersed in the lock storage space 2b.

  For this reason, the stopper cam 7 rotates around the supporting shaft 7a and is disengaged from the locking recess 3h of the lock cam portion 3b. Thereby, the sickle lock main body 3a can be rotated in the locking direction.

  Therefore, as shown in FIG. 3, when the user places a finger on the lower end in the figure of the indoor operation knob 10 from the indoor side such as a toilet and pushes it upward in the figure, the operation shaft 3e moves upward in the figure, As shown in FIG. 7A, the indoor operation knob 10 slides to the locking position. For this purpose, as shown in FIGS. 4 and 5, the sickle lock body 3a is rotated about its support shaft 3c by the upward movement of the operating shaft 3e in the figure and is engaged with the latching shaft 8a of the door frame 8. And locked.

  FIG. 7A is a front view when the indoor operation knob 10 is slid to the locked position. Between the upper end in the figure of the indoor operation knob 10 and the inner surface of the upper end of the indoor handle 4 in the figure. For example, a room-side gap ga into which about one finger of the user can be inserted is formed.

  On the other hand, as shown in FIG. 7 (b), the outdoor operation knob 9 slides to the locking position in conjunction with the operating shaft 3e, and the outdoor operation knob 9 is located below the outdoor operation knob 9 in the drawing, in the unlocked position. A display portion 11 of a required color such as “red” indicating “full” or “in use”, which has been shielded by the back surface 9 a of the operation knob 9, appears.

  A minute gap gb that is much narrower than the indoor gap ga is formed between the upper end in the figure of the outdoor operation knob 9 and the inner surface of the upper end part of the outdoor handle 5 in the figure.

  This minute gap gb is a minute gap into which even one user's finger cannot be inserted, and the outer surface of the outdoor operation knob 9 is formed of a smooth surface made of metal such as stainless steel, and there is no finger hook. There is a difficulty in unlocking by moving a certain outdoor operation knob 9 to a lower unlocking position in the figure.

  That is, since the outer surface of the outdoor operation knob 9 is configured to be a smooth surface without finger catching, for example, as shown in FIG. 1, the outer surface of the outdoor operation knob 9 tends to be pressed toward the indoor handle 4 side. For this reason, when the outer surface of the outdoor operation knob 9 is pressed toward the indoor handle 4 side, the leaf spring portion 12b of the lock member 12 protruding on the locking plate 13 as shown in FIG. As shown in FIG. 4, the locking plate 13 is pressed and crushed.

  For this reason, the pair of left and right projections 12c and 12d of the lock member 12 protrude relative to the locking plate 13 relative to the leaf spring portion 12b, and the pair of left and right engagements of the locking plate 13 as shown in FIG. It protrudes inward of the holes 13c and 13d, and is locked to the lower ends of the engagement holes 13c and 13d in the figure. For this reason, a slight gap is formed between the slider 12x and the opposing surface of the locking plate 13 by the tension of the leaf spring portion 12b of the lock member 12.

  As a result, the outdoor operation knob 9 is locked at the locking position, and sliding (moving) to the unlocking position is prevented.

  As a result, when the locking operation is performed by the indoor operation knob 10 on the indoor side, the unlocking cannot be performed by the outdoor operation knob 9 on the outdoor side.

  However, there are cases where it is more convenient to be able to perform the unlocking operation on the indoor side on the outdoor side due to some circumstances such as an emergency.

  In this case, as shown in FIG. 2 and FIG. 12A, only the upper part of the outer surface of the outdoor operation knob 9, that is, the slider 12 x side is pressed toward the indoor handle 4 side. Then, the slider 12x on the upper side of the outdoor operation knob 9 is pressed against the locking plate body 13a, and the slider 12x comes into contact with the opposing surface of the locking plate body 13a, so that the entire outer surface of the outdoor operation knob 9 is inclined. To do.

  For this reason, a minute gap gb is formed between the upper end of the outdoor operation knob 9 and the outdoor handle 5, and the outer opening of the minute gap gb is slightly enlarged.

  Then, in this state, as shown in FIG. 12B, next, a flat body such as a coin c or a tip of a driver is inserted into the minute gap gb, and the room operation is performed by the finger of the outdoor operation knob 9. Stop pressing.

  Then, as shown in FIG. 2, the leaf spring portion 12 b of the lock member 12 of the outdoor operation knob 9 is restored to the original position by the elastic restoring force, and a gap is formed between the locking plate body 13 a and the lock member 12. Is done.

  Accordingly, the engagement state between the pair of left and right convex portions 12c and 12d of the lock member 12 and the pair of left and right engagement holes 13c and 13d of the locking plate 13 shown in FIG. For this reason, the locked state of the lock member 12 and the locking plate 13 is released. Thereby, the outdoor operation knob 9 can be slid (moved) to the unlocked position.

  Therefore, in this unlocked state, that is, the state where the outdoor operation knob 9 is not pressed indoors, the outdoor operation is performed by the flat body such as the coin c or the driver tip d inserted in the minute gap gb. The upper end of the knob 9 in the figure is pressed and simply pushed down to the unlocking position below. Thereby, the locking operated inside the room can be unlocked outside the room.

  In other words, according to the lock 1 for the sliding door, the lock operated on the indoor side by the indoor operation knob 10 cannot be unlocked by the outdoor operation knob 9 on the outdoor side unless the unlocking method is known. For this reason, unlocking by mischief of a child who does not know this unlocking method can be prevented.

  Even when unlocked, when the outdoor operation knob 9 is pressed toward the indoor side puller 4, the locking member 12 is locked to the locking plate 13, so that the locking operation cannot be performed.

  However, in an emergency, etc., the lock can be unlocked by the above unlocking method.

  In the above embodiment, the case where the locking position is provided at the upper part of the indoor and outer handles 4 and 5 and the unlocking position is provided at the lower part has been described. However, the present invention is not limited to this. The vertical positional relationship between the locking position and the unlocking position may be reversed.

  While various embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the present invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the scope of the present invention.
