Description

  The present invention relates to a locking device for a shoji screen applied to a sliding sash, a single-drawing sash, and the like.

  In order to lock the sliding door such as a sliding sash, it is common to use a crescent that also serves as a draw, without mentioning a specific example. Is locked to a receiving bracket installed on the side of the other shoji's summoning side or on the vertical side, and the locking operation is performed.

  The crescent used as a shoji locking means has to perform a so-called locking operation as a separate operation after closing the shoji, and therefore requires a double operation of the closing operation and the locking operation, so that the operation is complicated. In some cases, the locking operation may be forgotten, which is not preferable for crime prevention.

  The present invention has been devised to provide a locking device suitable for crime prevention by paying attention to the drawbacks of such a conventional example and automatically performing a locking operation in conjunction with a shoji closing operation.

  A locking piece that has a hook-shaped receiving piece projecting in one direction on the other side of the door on the vertical frame side or the shoji door toe, and is rotated and locked to the receiving piece when the shoji is closed. Is pivotally attached to the other one, and a longitudinally moving piece that is connected to the locking piece to rotate it is assembled to the other one, and a receiving provided on the other one. An actuating piece that is provided with a regulating piece on the longitudinal moving piece that is artificially locked to the edge and regulates the rising of the longitudinal moving piece due to spring biasing, and that separates the regulating piece from the receiving edge when the shoji is closed. Is configured to protrude from the one side.

  According to the present invention, when the door toe is moved in the vertical frame direction of the window frame when the shoji is closed, it is locked to the receiving edge provided on either the door toe or the vertical frame and is biased by the spring. The restricting part projecting on the other side opens the locked state of the restricting part that restricts the ascent of the vertically moving piece with respect to the receiving edge. The locking piece that is raised and connected to the upper end of the longitudinally moving piece can be rotated and locked to the receiving piece on the other one side to automatically lock the shoji.

  Therefore, a sliding door device suitable for crime prevention can be obtained without forgetting the locking operation.

  The drawings show an embodiment of a locking device for a shoji according to the present invention, FIG. 1 is a longitudinal sectional view of the main part, FIG. 2 is a transverse sectional view of FIG. 1, and FIG. 4 is a sectional view taken along line xx of FIG. 3, and FIG. 5 is a front view schematically showing a sliding sash.

  In the embodiment, the present invention is applied to a so-called sliding sash A in which the inside and outside shojis d ′ and d are different from each other. The sliding sash A in the embodiment is a crescent to the summon 1 ′ of the shoji d ′. 2 is provided with a receiver on the summit of the shoji d, and when the shoji is closed, the crescent 2 is locked to the receiver and is locked in the summit of the inner and outer shoji d, d ′. The locked state is also obtained in the relationship between the door toe 3 and 3 'of d and d' and the vertical frames 4 and 4 'of the window frame w, that is, by using the device according to the present invention (the locking device by the crescent and the like). By using it together, it is expected to have a further crime prevention effect.

  Needless to say, the present invention can also be applied to a one-way sash.

  Hereinafter, the locking device of the relationship between the outer frame d of the sliding sash A of the embodiment, the leading edge 3 and one vertical frame 4 of the window frame w will be described. The only difference between the locking device of the door toe 3 'and the other one vertical frame 4' is that each member such as the locking piece 6 is symmetrically arranged with respect to the inner edge d 'side. Since the remaining points have the same configuration, the detailed description thereof is omitted.

  The door toe cage 3 (of the external shoji d) protrudes from the hollow main body 3a having a rectangular cross section and the inner and outer parts 3a ′ and 3a ″ of the hollow main body 3a so as to be opposed to each other in the indoor and outdoor directions. It is composed of inner and outer fin pieces 3b, 3b, 3c, 3c, and the glass panel 7 is engaged with an engagement groove formed by the inner fin pieces 3b, 3b and the inner piece 3a ″. In combination, the outer fin pieces 3c and 3c are engaged with the indoor and outdoor pieces 4a and 4a of the vertical frame 4 when the shoji is closed so as to improve the water tightness together with the sealing material not shown. It is.

  A rectangular hollow device base frame 8 is engaged with a vertical middle portion of the hollow main body 3a of the door toe 3 through a window provided on the indoor side piece 3a "" of the main body 3a. The outer part piece 3a ″ is fixed to the main body 3a with a bolt 9, and the outer part piece 3a ″ of the main body 3a and the part of the device base frame 8 overlapping the outer part piece 3a ″ are attached to the device base frame 8. The hook-shaped locking piece 6 that enters and exits between the outer fin pieces 3c and 3c while rotating through the doorway 10 provided in the piece 8a is supported by a support shaft 11 that is laterally provided on the base frame 8 in the base piece 6b. It is pivotally pivoted.

  The locking piece 6 is composed of a slightly circular base piece 6b and a hook-shaped tip piece 6a projecting from the base piece 6b, and the tip piece 6a passes through the doorway 10 and the door piece main body 3a (device base frame). 8) The door toe 3 is engaged between the indoor and outer pieces 4a, 4a of the vertical frame 4 (when the shoji is closed) and protrudes between the outer fin pieces 3c, c so that the door contact 12 of the vertical frame 4 ( As described above, it is provided on the door toe 3 so as to be engaged with the hook-shaped receiving piece 13 projecting from the indoor / outdoor pieces 4a and 4a).

  The base piece 6b of the locking piece 6 includes a notch 14 which is pivotally attached to the apparatus base frame 8, that is, the door rod 3 by the support shaft 11 so as to be able to rotate in the horizontal direction, and is long in the radial direction of the support shaft 11, The notch 14 is engaged with (connected to) the longitudinally moving material 15 (at the upper end portion of the longitudinally moving material 15) by engaging a pin 16 provided on the longitudinally moving material 15 side.

  The notch 14 provided in the base piece 6b of the locking piece 6 may be replaced with a long hole, and the longitudinal direction of the notch 14 is arranged along the radial direction of the support shaft 11. When the pin 16 moves along the notch 14 along with the longitudinal movement of the pin 16, the locking piece 6 is smoothly rotated around the support shaft 11, and the locking and disengaging operation of the locking piece 6 with the receiving piece 13 is stable. To do. Therefore, if the locking piece 6 is rotated about the support shaft 11 by pressing the locking piece 6 of the pin 16 (with respect to the edge of the notch 14), the notch 14 (originally replacing the notch) is used. The long holes) do not necessarily have to follow the radial direction.

  The longitudinally moving member 15 is vertically engaged with the device base frame 8 below the locking piece 6 and has a vertically long groove-shaped main portion 15a having an opening in the lower side and the outdoor side surface. The upper part 15a 'of the part 15a is provided with upright part pieces 15b, 15b which are erected relative to each other via the locking piece 6, and the pin 16 installed between the upright part pieces 15b, 15b is attached to the locking piece 6 It is engaged with the notch 14 of the base piece 6b and is connected to the locking piece 6. Between the pressure receiving piece 17 provided at the intermediate portion in the vertical direction of the apparatus base frame 8 and the upper piece 15a 'of the main portion 15a. It is arranged so as to be urged in the upward direction by a coil spring 18 interposed therebetween. Then, the locking piece 6 is pressed via the pin 16 by the ascending of the longitudinally moving member 15 due to this urging, and is urged to rotate in a direction to be locked to the receiving piece 13, and is locked to the receiving piece 13. The state is maintained by the urging of the coil spring 18.

  Further, the return lever 19 is connected to the indoor side piece 15 ″ of the main body portion 15 a of the longitudinal moving material 15 through the neck portion 19 a, and the neck portion (connecting portion) 19 a is provided in the apparatus base frame 8. The return lever 19 is overlapped with the indoor side piece 3 a ″ ″ so as to engage with the long hole 20, and the return lever 19 is installed on the outside (indoor side) of the door toe 3 on the indoor side. is there.

  Then, the return lever 19 is continuously provided, the main body part piece on the side of the outer fin part piece 3c of the hollow main body 3a adjacent to the indoor side part piece 15a '' of the longitudinally moving material main part 15a, and the The slit 29 is provided between the indoor side piece 15a ″ and the main piece is provided with elasticity on the free end side at the lower end so that the regulating piece 21 (the longitudinal moving material 15 is made of synthetic resin). The locking protrusion 22 is formed on the outer surface of the free end portion of the restricting piece 21 (on the outer side piece 3a ″ side of the door tip main body 3a or on the side facing the door stop 12). A receiving edge 23 that the locking protrusion 22 locks against the urging force of the coil spring 18 is provided with the device base frame 8 and the door end rod main body 3a (the outer side piece 3a ″ thereof). It is comprised by the upper edge of the fitting opening 25 of the action | operation piece 24 provided opening.

  The actuating piece 24 is provided on the apparatus base plate 26 attached to the door stop 12 of the vertical frame 4 with bolts 9A together with the receiving piece 13 so as to protrude below the receiving piece 13 in the direction of the door toe 3. Therefore, when the shoji is closed, it is inserted into the insertion opening 25, and when it is inserted, the restriction piece 21 (the lower end of the restriction piece 21 in the embodiment) is pressed to release the engagement state of the engagement protrusion 22 with respect to the receiving edge 23. Thus, the restriction of the biasing force of the coil spring 18 is released.

  The positional relationship between the operating piece 24 and the regulating piece 21 is, of course, a positional relationship in which the locking protrusion 22 is separated from the receiving edge 23 when the operating piece 24 (the tip) contacts the regulating piece 21. At the same time, the receiving piece 13 is also arranged in a positional relationship in which the locking piece 6 can be locked, and the position adjustment can be performed by the engagement positional relationship between the bolt 9 </ b> A and the device substrate 26 and the long hole 27.

  Accordingly, the operation of the return lever 19 with the fingertip (lowering) causes the longitudinally moving material 15 to descend against the bias of the coil spring 18, and the regulation piece 21 provided in the longitudinally moving material 15 is associated with the downward movement. The stop protrusion 22 also descends while being in sliding contact with the inner surface of the piece 8a of the device base frame 8 (the door toe main part 3a), reaches the position of the fitting entrance 25, and its elasticity acts on the fitting entrance 25. It latches on the receiving edge 23 comprised with an edge. In this state, the notch 14 at the base of the locking piece 6 is pulled down by the pin 16 of the longitudinal moving material 15, so that the locking piece 6 rotates and the tip piece 6 a is in an upright state, so to speak. It will be in the state accommodated in the hollow part 3a.

  At this time, when the shoji d is moved in the closing direction, that is, moved in the direction of the door toe 3 and the door stop 12, the door 25 protrudes from the insertion slot 25 to the restriction piece 21 and the vertical frame door stop 12 in this position. The actuating piece 24 presses the restricting piece 21 relatively, and the engaging protrusion 22 provided on the pressed restricting piece 21 is momentarily released from the engaging state with respect to the receiving edge 23, and at the same time, the coil spring is released. The vertical motion material 15 rises along the hollow portion 3a of the door toe 3 by the elasticity (biasing) of 18 and the pin 16 installed on the upper end portion of the vertical motion material 15 by the rise of the vertical motion material 15. Presses the edge of the notch 14, and as a result, the locking piece 6 rotates about the support shaft 11, and the hook-shaped tip piece 6a protrudes from the hollow portion 3a through the doorway 10 and is received at this position. It is locked to the piece 13 and locked, and this state is due to the biasing action of the coil spring 18 as described above. It is maintained Te.

  When the shoji is opened, the return lever 19 is operated to lock the latching protrusion 22 of the restricting piece 21 to the receiving edge 23, thereby obtaining the state when the shoji is opened.

  Note that the receiving piece 13 may be arranged on the side of the shoji d (the door toe 3), and the locking piece 6 may be arranged on the side of the window frame w (the vertical frame 4). Since the material 15 and other members are also to be installed, the vertical frame 4 has a form (configuration) corresponding thereto.
