However, in such a conventional open-and-close surface lattice, since it is installed outside the window and protrudes from the window to the outside, the use of the outdoor space of the window is restricted, and the window portion There is a problem of detracting from the appearance of. In addition, there is a problem that it cannot be attached to a window that opens to the outdoor side by a vertical sliding window or the like.
In addition, a locking device is required for the surface lattice for crime prevention. It is desirable that this locking device is easy to operate, and moreover, it is desirable that it can be operated safely.

  The present invention has been made in view of the above circumstances, and by installing the face lattice on the indoor side of the window sash, the face lattice is prevented from projecting outside the window, and the window portion An object of the present invention is to provide an open / close type face lattice that can be maintained in the appearance and has a locking device that is easy to operate and safe.

In order to achieve the above object, the surface lattice according to claim 1 is an openable and closeable surface lattice installed on the indoor side of a window sash of an opening of a building,
A pair of guide rails arranged opposite to each other on the indoor side of the window sash, a plurality of lattice members provided movably along these guide rails, and a connecting member for connecting adjacent lattice members together A blindfold provided along one side of the opening of the building and capable of accommodating all or part of the lattice member, and preventing the lattice member from moving toward the blindfold when the surface lattice is closed And a locking device
The locking device is
A first protrusion that is pivotally provided on the guide rail and that is pushed by the lattice member by the movement of the lattice member at the time of closing the surface lattice to rotate the lock member; and A locking member having a second projecting portion that is positioned on the blindfolded portion side of the lattice member with rotation and prevents movement of the lattice member to the blindfolded portion side;
A stopper that engages with the lock member to prevent rotation of the lock member when the lock member is prevented from moving;
When the engagement between the stopper and the lock member is released, the lock member is prevented from rotating, and the lock member is rotated by moving the lattice member at the tip to the opposite side of the blindfold. A safety stopper for releasing the movement prevention is provided.

In the first aspect of the invention, when the surface lattice is closed, that is, when the lattice member moves along the guide rail in a direction away from the blindfold, the lattice member at the tip pushes the first protrusion of the lock member. The lock member rotates, and with the rotation of the lock member, the second protrusion of the lock member is positioned on the blindfold side of the lattice member at the distal end, thereby moving the lock member toward the blindfold side of the lattice member at the distal end. Movement is prevented. At this time, a stopper is engaged with the lock member to prevent the lock member from rotating.
Even if the engagement between the stopper and the lock member is released, the safety stopper prevents the lock member from rotating. Therefore, the lattice member is still restrained by the lock member, and the lattice opening operation using a spring or the like is performed. The lattice member does not move immediately due to the auxiliary member or the like. When the operator moves the lattice member at the tip to the side opposite to the blindfold, the rotation prevention of the lock member of the safety stopper is released, and the rear lattice can be opened.

  According to a second aspect of the present invention, in the invention according to the first aspect, the stopper is provided rotatably on the guide rail, and an urging member is provided between the stopper and the lock member. The locking member rotates against the urging force of the urging member when the face lattice is closed, and the urging force of the urging member engages the engaging portion between the locking member and the stopper. It is characterized by combining.

  In the invention according to claim 2, when the surface lattice is closed, that is, when the lattice member moves along the guide rail in a direction away from the blindfold, the lattice member at the tip pushes the first protrusion of the lock member. The lock member rotates against the urging force of the urging member provided between the lock member and the stopper, and the lock member is moved to the blind portion of the lattice member at the tip as the lock member rotates. The second projecting portion is located, thereby preventing the leading lattice member from moving toward the blindfolded portion. Furthermore, when the movement of the lattice member of the lock member is prevented, the engaging portion of the lock member and the stopper is engaged by the urging force of the urging member, and the lock member is prevented from rotating.

  According to a third aspect of the present invention, there is provided the surface lattice according to the second aspect, wherein the stopper is rotated against the urging force of the urging member by turning a key, and the stopper, the locking member, An engagement release member for releasing the engagement is provided.

  In the invention described in claim 3, if there is no key for the disengagement member, the engagement between the stopper and the lock member cannot be released, and therefore the face lattice cannot be opened.

  According to the surface lattice of claim 1, since the surface lattice is installed on the indoor side of the window sash, the surface lattice does not protrude to the outside of the window, and the appearance of the window portion can be kept beautiful. it can. Further, in order to close the surface lattice, when the lattice member is moved in the direction away from the storage portion along the guide rail, the leading lattice member pushes the first protrusion of the lock member, and the leading lattice member Since the movement to the storage unit side is prevented, that is, the surface lattice is locked, the surface lattice can be easily locked. Furthermore, even if the engagement between the stopper and the lock member is released, the grid member is not moved immediately by the safety stopper, which is safe and the operator moves the grid member at the tip to the side opposite to the blindfold. Only by making it possible to cancel the rotation prevention of the locking member of the safety stopper and to open the face lattice, the operation is simple.

  According to the surface grid of the second aspect, the same effect as that of the invention according to the first aspect can be obtained, and in order to close the surface grid, the lattice member is arranged along the guide rail. If the grid member at the tip pushes the first protrusion of the lock member, the tip grid member is prevented from moving toward the housing portion, that is, the surface grid is moved. Since it is in the locked state, it is possible to easily lock the surface lattice. In addition, when the lock member is prevented from moving the lattice member, the engaging portion of the lock member and the stopper is engaged by the urging force of the urging member, so that the locking operation of the surface lattice can be performed more easily. The locked state can be made stronger.

  According to the surface grid of the third aspect, it is possible to obtain the same effect as that of the second aspect of the invention. Since the engagement cannot be released and the face lattice cannot be opened, it is more advantageous in terms of crime prevention.

On the indoor side of the frame body 5, a lifting and lowering screen door 7 that opens and closes in the vertical direction is attached.

In the opening K of the building, a surface grid 20 is installed on the indoor side of the vertical sliding window sash 1 as follows.
That is, along the left and right frame G, a pair of guide rails 21, 21 are arranged to face each other and are fixed to the housing by screws 22. A plurality of pipes (lattice members) 32 that are guided by the guide grooves 23 and 23 of the guide rails 21 and 21 and are provided at intervals in the vertical direction are provided to be movable in the vertical direction.

  At both ends of each pipe 32, there are provided insertion portions 33, 33 inserted into the respective guide grooves 23, 23, respectively. On the pipe 32 side of the insertion portion 33, a neck portion 34 that is recessed in the indoor / outdoor direction is formed, and this neck portion 34 is inserted into the narrowed portion 24 that is narrowly narrowed in the guide groove 23, whereby the narrowed portion The pipe 32 moves in the vertical direction while the neck portion 34 is restricted from moving in the left-right direction and the indoor / outdoor direction by 24.

  As shown in FIG. 3 and FIG. 4, the adjacent pipes 32 are disposed between the respective insertion portions 33 of the respective pipes 32 and the adjacent upper insertion portions 33 and between the adjacent lower insertion portions 33. Wires (connecting members) 36, 36 for connecting the two are provided. That is, the upper ends of the wires 36 are fixed to the upper insertion portion 33 of the insertion portions 33 and 33 adjacent to each other, and are inserted into the holes provided in the lower insertion portion 33, When the side insertion portion 33 is lowered and comes to the lower end portion of the wire 36, the lower insertion portion 33 is locked to the enlarged diameter locking portion 37 provided at the lower end portion of the wire 36. The lower insertion portion 33 is prevented from further descending. As a result, as shown in FIG. 3, the interval between the lower insertion portion 33 and the upper insertion portion 33 is kept constant, and the lower insertion portion 33 is placed on the upper side as shown in FIG. When approaching the insertion portion 33, the lower insertion portion 33 can be freely raised without being restricted by the wire 36. In other words, the interval between the adjacent pipes 32 and 32 is kept constant, and the lower pipe 32 can freely rise and approach the upper pipe 32 without being restricted by the wire 36. .

  As shown in FIG. 5, the insertion portions 33A and 33A at both ends of the lowermost pipe 32 extend longer to the outside (opposite the pipe 32) than the other insertion portions 33. An attachment portion 38 to which one end portion (lower end portion) of the wire 48 for lifting the pipe 32 is fixed is provided.

  As shown in FIG. 1, a box (blindfold) 41 is disposed on the upper part of both guide rails 21, 21 and is fixed to the upper casing. In the box 41, a cylindrical winding member 42 for winding the pipe 32 is rotatably provided. That is, as shown in FIGS. 5 to 8, the shaft 43 is fixed between the left and right side plates of the box 41 so as to extend in the left-right direction. The cylindrical members 44, 44 are rotatably fitted, and the end portions of the cylindrical winding member 42 are inserted outside the large diameter portions of the rotating members 44, 44, respectively, and fixed by screws. Yes. A torsion coil spring (biasing member) 46 is provided between the take-up member 42 and the shaft 43, and this torsion coil spring 46 is elastically deformed when the pipe 32 is unwound and thereby takes up. The member 42 urges the pipe 32 in the winding direction to rotate the winding member 42 in the winding direction.

  A bevel wheel 47 that gradually becomes smaller in diameter toward the outside is fixed to the outside of the small diameter portion of each cylindrical member 44 by a screw. In each bevel wheel 47, a groove around which a wire (drawing member) 48 for pulling up the pipe 32 is wound is formed in a spiral shape. One end portion (upper end portion) of the wire 48 is fixed to the large diameter side of the bevel wheel 47, while the other end portion (lower end portion) is connected to the attachment portion 38 of the lowermost pipe 32 as described above. All the pipes 32 are pulled up together by pulling up the lowermost pipe 32 with a wire 48.

  In the box 41, a winding guide 51 is fixed to the outside of each cylindrical member 44, and each pipe 32 wound around the winding member 42 is guided by each winding guide 51, so that the winding member 42 It is neatly wound around the outer periphery. A hook-shaped end of a torsion coil spring (biasing member) 53 is engaged with the neck 34 of the proximal end pipe 32, that is, the neck 32 of the pipe 32 wound up first, and the torsion coil spring 53 The other end is locked to the box 41. The torsion coil spring 53 is elastically deformed when the pipe 32 is wound around the winding member 42, thereby urging the pipe 32 in a direction of being drawn out from the winding member 42. The pipe 32 is provided to facilitate feeding.

  When the pipe 32 at the front end, that is, the lowermost pipe 32 is lowered to close the surface lattice 20, the winding member 42 rotates, and the pipes 32 are successively fed out from the winding member 42. At this time, the wires 36 provided between the insertion portions 33, 33 of the adjacent upper and lower pipes 32, 32 are expanded to a predetermined distance between the adjacent upper and lower pipes 32, 32, and each pipe 32 is expanded. Are successively fed from the winding member 42. Further, a wire 48 for pulling up the pipe 32 is fed out from the bevel wheel 47. Further, as the winding member 42 rotates in the feeding direction of the pipe 32, the torsion coil spring 46 is elastically deformed, and the winding member 42 is biased in the winding direction of the pipe 32.

  On the other hand, when the surface lattice 20 is opened, that is, when the winding member 42 is rotated in the winding direction of the pipe 32 by the torsion coil spring 46, the wire 48 is wound around the bevel wheel 47, whereby the lowermost pipe. 32 goes up. When the lowermost pipe 32 rises, the wire 36 provided between the insertion portions 33, 33 of the adjacent upper and lower pipes 32, 32 rises and the lower pipe 32 rises. Since the lower pipe 32 is sequentially approached to the upper pipe 32, the lower pipe 32 is sequentially stacked on the lower pipe 32. The pipes 32 are in close contact with each other, and the pipes 32 are wound around the winding member 42.

  The bevel wheel 47 is formed so as to gradually become smaller in diameter toward the outer side, and the wire 48 is gradually wound from the large-diameter portion by the groove of the small-diameter portion. The amount of winding is increased using the large diameter portion, and then the load gradually increases, so that the winding is gradually performed on the small diameter portion.

Next, the locking device R for the surface lattice 20 will be described.
As shown in FIGS. 9 to 11, a plate-like lock member (rotating member) 61 is provided at the lower end of each guide rail 21. The lock member 61 is rotatably attached by a pin 64 to an attachment plate 63 fixed to a wall 25 in the guide rail 21 orthogonal to the guide groove 23 of the guide rail 21 by a screw 62. A pair of second projecting portions 65A and a first projecting portion 65B are formed at the distal end portion of the lock member 61, and a recess between the second projecting portion 65A and the first projecting portion 65B. The opening width of 66 is set slightly larger than the outer diameter of the pipe 32.
A stopper 67 is rotatably attached to the attachment plate 63 by a pin 68 on the lower side of the lock member 61. The upper end portion of the stopper 67 is formed in a mountain shape. A tension coil spring (biasing member) 69 is provided between the stopper 67 and the lock member 61, and by this tension coil spring 69, the stopper 67 and the lock member 61 are close to each other on the opposite side to the guide groove 23. It is energized to do.

When the surface lattice 20 is open, as shown in FIG. 9, the lock member 61 is urged by the tension coil spring 69 so that the second protrusion 65A and the first protrusion 65B face upward. The first protrusion 65B on the lower side protrudes into the guide groove 23. On the other hand, the stopper 67 is in an oblique state, and the mountain-shaped top portion 71 is in contact with the end portion of the rear end surface of the lock member 61.
When the lowermost pipe 32 descends in order to close the surface lattice 20, the first protrusion 65B on the lower side of the lock member 61 is pushed to lock against the urging force of the tension coil spring 69. The member 61 is rotated around the pin 64 toward the guide groove 23 (clockwise in the figure). At this time, the stopper 67 is rotated to the opposite side of the guide groove 23 by the rear end surface of the lock member 61 with the rotation of the lock member 61, and becomes substantially upright (see FIG. 10).
When the surface lattice 20 is fully closed, that is, when the lowermost pipe 32 is lowered to the lowest position, as shown in FIG. 11, the lock member 61 moves the second protrusion 65A and the first protrusion 65B downward. The upper second protrusion 65 </ b> A protrudes into the guide groove 23. The upper second protrusion 65A prevents the pipe 32 from moving upward and enters a locked state. At this time, the mountain-shaped top portion 71 of the stopper 67 is engaged with the concave portion 72 on the side surface of the lock member 61 and is engaged with each other by the urging force of the tension coil spring 69, whereby the lock member 61 does not move in this state. To be done.

  As shown in FIGS. 2 and 11, an engagement release member 75 using a key 74 is attached in the vicinity of each stopper 67 of each guide rail 21. By turning the key 74, the pressing piece 76 of the disengagement member 75 is pressed downward against the urging force of the tension coil spring 69 against the bent portion 78 of the lower end portion of the stopper 67. As a result, the top 71 of the stopper 67 is separated from the recess 72 of the lock member 61 and the engagement is released, and the lock member 61 is released from the top 71 of the stopper 67 by the urging force of the tension coil spring 69. It rotates so that it may shift | deviate from the engagement position of the recessed part 72 of 61. FIG. Therefore, the lock member 61 can be freely rotated by turning the key 74. When the key 74 is rotated once, the above engagement can be released. Therefore, when the hand is released from the key 74, the pressing piece 76 is moved from the pressing position to the original position by the torsion coil spring (biasing member) 79. It comes to return.

  As shown in FIGS. 9 to 11, a plate-like closing member 81 is rotatably attached to the lock member 61 by a pin 82. As the locking member 61 rotates about the pin 64 toward the guide groove 23 side (clockwise) of the guide rail 21, the pin 82 moves toward the guide groove 23 side (clockwise) around the pin 64. By gradually rotating, the closing member 81 gradually moves toward the guide groove 23 so as to close the opening of the guide groove 23.

  A plate-like interlocking member 84 is provided at the upper end of the guide rail 21. The interlocking member 84 is substantially L-shaped, and a bent portion thereof is rotatably attached to a mounting plate 86 fixed to the upper end portion of the wall 25 by a screw 85 by a pin 87. The upper end of the closing member 81 is rotatably attached to one end of the interlocking member 84 by a pin 88, and the upper end of an elongated plate-like connecting member 91 is attached to the other end by a pin 92. It is pivotally attached. A lock member 61 is rotatably attached to the lower end portion of the connecting member 91 by a pin 94. As a result, when the lock member 61 rotates about the pin 64 toward the guide groove 23 side (clockwise) of the guide rail 21, this rotational movement is transmitted to the interlocking member 84 via the connecting member 91, and the interlocking member 84. Rotates around the pin 87 toward the guide groove 23 (clockwise), and the upper end of the closing member 81 moves toward the guide groove 23 along with this rotation, and the opening of the guide groove 23 Block. Therefore, the lower end portion of the closing member 81 is moved to the guide groove side by the lock member 61, and the upper end portion is moved by the interlocking member 84, so that the closing member 81 closes the entire opening portion of the guide groove 23.

  On the side of the closing member 81 on the guide groove 23 side, a recess 96 is formed at a position corresponding to each pipe 32. When the closing member 81 covers the guide groove 23, the recess 96 is placed in each recess 96. Each pipe 32 is positioned so that interference between the closing member 81 and each pipe 32 is avoided.

  In the surface lattice 20 configured as described above, when the pipe 32 is drawn out from the winding member 42 and lowered to close the surface lattice 20, as shown in FIG. The first protrusion 65B on the lower side of the lock member 61 is pushed downward, and the lock member 61 is moved toward the guide groove 23 of the guide rail 21 against the biasing force of the tension coil spring 69 as shown in FIG. The pin 64 is turned around (clockwise in the figure). At this time, the stopper 67 is rotated to the side opposite to the guide groove 23 by the rear end surface of the lock member 61 as the lock member 61 is rotated, and becomes substantially upright. Further, as the locking member 61 rotates, the lower end portion of the closing member 81 attached to the locking member 61 rotates toward the guide groove 23 around the pin 64, and at the same time, the closing member attached to the interlocking member 84. The upper end portion of 81 is rotated around the pin 87 toward the guide groove 23, whereby the closing member 81 moves toward the guide groove 23.

  When the lowermost pipe 32 is lowered to the lowest position, as shown in FIG. 11, the lock member 61 further rotates, and the lock member 61 sets the second protrusion 65A and the first protrusion 65B to the lower side. The upper second protrusion 65A protrudes into the guide groove 23, and the pipe 32 is prevented from moving upward by the second protrusion 65A. It becomes a state. At this time, the mountain-shaped top portion 71 of the stopper 67 is engaged with the concave portion 72 on the side surface of the lock member 61 and engaged with each other by the urging force of the tension coil spring 69 so that the lock member 61 does not move in this state. Is done. Further, with the rotation of the lock member 61, the closing member 81 moves to the guide groove 23 side and closes the opening of the guide groove 23.

  On the other hand, to open the surface lattice 20, first, the key 74 is turned, and the bent portion 78 of the stopper 67 is moved downward against the urging force of the tension coil spring 69 by the pressing piece 76 of the engagement release member 75. Push. As a result, the top portion 71 of the stopper 67 is separated from the recess 72 of the lock member 61 and the engagement is released. Thus, the lock member 61 can be freely rotated.

  When the lock member 61 can freely rotate, the winding member 42 is rotated in the winding direction of the pipe 32 by the torsion coil spring 46, and the wire 48 is wound around the bevel wheel 47, so that The side pipe 32 rises. When the lowermost pipe 32 is raised, the second protrusion 65A on the upper side of the lock member 61 is pushed upward, so that the lock member 61 is on the side opposite to the guide groove 23 of the guide rail 21 (counterclockwise in FIG. 11). Direction) about the pin 64. At this time, the locking member 61 is given a force to rotate by the urging force of the tension coil spring 69. As the locking member 61 rotates, the closing member 81 moves away from the guide groove 23 of the guide rail 21 so that the opening of the guide groove 23 is opened and each pipe 32 can be freely raised. Thus, each pipe 32 is wound around the winding member 42.

In this surface lattice 20, since the surface lattice 20 is installed on the indoor side of the window sash 1, the surface lattice does not protrude outside the window, and the appearance of the window portion can be kept beautiful. .
Further, since the closing member 81 that closes the opening of the guide groove 23 of the guide rail 21 when the surface lattice 20 is closed is provided, the screw in the guide rail 21 or the member that moves the lattice member 32 may be removed. Therefore, even when the window sash 1 is opened from the outdoor side, it is possible to prevent the surface lattice 20 from being opened, which is effective for crime prevention.

  Further, in order to close the surface lattice 20, when the lattice member 32 is fed out from the winding member 42 in the box 41 and the lattice member 32 is lowered along the guide groove 23 of the guide rail 21, the lattice member at the tip end 32 pushes the first protrusion 65B of the lock member 61 downward to rotate the lock member. As the lock member rotates, the closing member 71 moves to the guide groove 23 side of the guide rail 21. Since the opening of the guide groove is closed, the closing operation of the closing member 81 can be easily performed.

  Further, the interlocking mechanism between the locking device R and the closing member 81 that prevents the lattice member 32 from moving toward the blindfold 41 when the surface lattice 20 is closed can be configured as shown in FIGS. . As shown in FIGS. 12 to 14, the configuration of the lock member 61, the stopper 67, the disengagement member 75 using the key 74, the closing member 81, etc. is substantially the same as the configuration shown in FIGS. 9 to 11. The same components are denoted by the same reference numerals, and the description thereof is omitted or simplified.

In the present embodiment, the lock member 61 and the elongated plate-like interlocking member 101 are connected by an operation link piece 102. The interlocking member 101 is inserted into a guide portion provided in the guide rail 21 and extending in the vertical direction so as to be movable up and down.
The interlocking member 101 and the closing member 81 are connected to each other by link pieces 104 and 104 at two locations, upper and lower. The closing member 81 is formed with guide grooves 105, 105 that extend horizontally at two locations on the upper and lower sides, and a pin 106 provided on the guide rail 21 side is inserted into each guide groove 105, whereby the closing member 81 is inserted. Is designed to move horizontally.

  Further, a plate-shaped safety stopper 111 is rotatably attached to the lock member 61 by a pin 121. A locking portion 123 bent toward the lock member 61 is formed at one end of the safety stopper 111 (see FIG. 15), and a locking window portion 125 is formed in the lock member 61 (see FIG. 15). 16). The locking part 123 is inserted into the window part 125 of the lock member 61, and the tip part projects from the opposite side of the lock member 61. A tension coil spring (biasing member) 126 is provided between the locking stopper 123 side portion of the safety stopper 111 and the outer peripheral portion of the lock member 61. The safety stopper 111 is urged counterclockwise in FIGS. 12 to 14 by the tension coil spring 126, so that the locking portion 123 comes into contact with the edge of the window portion 125 of the lock member 61. It has become. At this time, the other tip portion of the safety stopper 111 protrudes into the recess 66 of the lock member 61. When the projecting portion 127 projecting into the recess 66 is pressed, the safety stopper 111 rotates clockwise around the pin 121 against the urging force of the tension coil spring 126. At this time, the locking portion 123 moves in the window portion 125 of the lock member 61. The biasing force of the tension coil spring 126 that biases the safety stopper 111 is set to be smaller than the biasing force of the tension coil spring 69 that biases the lock member 61. Further, in this embodiment, the recess 66 has an entrance that is slightly larger than the outer diameter of the pipe 32, and the entrance is wide at the back.

When the locking member 61 rotates around the pin 64 in a state where the protruding portion 127 of the safety stopper 111 protrudes into the recess 66 of the locking member 61, the protrusion (locking portion) 131 provided on the guide rail 21 The locking portion 123 of the safety stopper 111 comes into contact (see FIG. 17). When the locking part 123 comes into contact with the protrusion 131, the locking part 123 crosses the inside of the window part 125 of the lock member 61, so that the edge part of the window part 125 hits the locking part 123 and the lock member 61 rotates. It becomes impossible to move.
On the other hand, when the protruding portion 127 of the safety stopper 111 is pressed and pushed out from the recess 66 of the lock member 61, the distance between the locking portion 123 and the pin 64 that is the rotation center of the lock member 61 is short. Thus, even if the lock member 61 rotates about the pin 64, the locking portion 123 of the safety stopper 111 does not contact the protrusion 131, and therefore the lock member 61 can freely rotate.

  In the surface lattice 20 using such a locking device R, when the pipe 32 is drawn out from the winding member 42 and lowered to close the surface lattice 20, as shown in FIG. The pipe 32 pushes the first protrusion 65B on the lower side of the lock member 61 downward, and the lock member 61 is guided to the guide rail 21 against the urging force of the tension coil spring 69 as shown in FIG. The pin 64 is rotated around the groove 23 side (clockwise in the figure). At this time, this rotational movement of the lock member 61 is transmitted to the interlocking member 101 by the link piece 102, and the interlocking member 101 linearly moves upward. The upward linear movement of the interlocking member 101 is transmitted to the closing member 81 by the link pieces 104 and 104, and the closing member 81 moves horizontally toward the guide groove 23 side.

  When the pipe 32 pushes the first projecting portion 65B of the lock member 61, the projecting portion 127 of the safety stopper 111 projecting into the recessed portion 66 is pressed, whereby the safety stopper 111 of the tension coil spring 126 is pressed. It rotates clockwise around the pin 121 against the urging force and is pushed out from the inside of the recess 66, and the locking part 123 moves in the window part 125 of the locking member 61, and the locking part 123 and the locking member The distance from the pin 64, which is the rotation center of 61, is shortened. Therefore, even if the lock member 61 rotates clockwise around the pin 64, the locking portion 123 rotates beyond the protrusion 131 without hitting the protrusion 131.

  When the lowermost pipe 32 is lowered to the lowest position, as shown in FIG. 14, the lock member 61 is further rotated, and the lock member 61 moves the second protrusion 65A and the first protrusion 65B downward. The upper second protrusion 65A protrudes into the guide groove 23, and the pipe 32 is prevented from moving upward by the second protrusion 65A. It becomes a state. At this time, the mountain-shaped top portion 71 of the stopper 67 is engaged with the concave portion 72 on the side surface of the lock member 61 and engaged with each other by the urging force of the tension coil spring 69 so that the lock member 61 does not move in this state. Is done. Further, with the rotation of the lock member 61, the closing member 81 moves to the guide groove 23 side and closes the opening of the guide groove 23.

  On the other hand, in order to open the surface lattice 20, from the state shown in FIG. 14, first, the key 74 is turned, and the bent portion of the stopper 67 is turned to the urging force of the tension coil spring 69 by the pressing piece of the disengagement member 75. Push down. As a result, the top portion 71 of the stopper 67 is separated from the recess 72 of the lock member 61 to be disengaged, and the lock member 61 is released from the top portion 71 of the stopper 67 and the recess 72 of the lock member 61 by the biasing force of the tension coil spring 69. The lock member 61 is released from the restraint of the stopper 67.

  However, at this time, since the pipe 32 is on the second protrusion 65A side of the recess 66 of the lock member 61, the protrusion 127 of the safety stopper 111 protrudes into the recess 66 of the lock member 61. 123 hits the protrusion 131 and the rotation of the lock member 61 is prevented. Thereby, when the key 74 is turned and the engagement of the locking member 61 of the stopper 67 is released, the pipe 32 is prevented from rising immediately.

  In order to release the rotation blocking state of the lock member 61 by the safety stopper 111, the pipe 32 is manually pushed down slightly. As a result, the pipe 32 moves to the first protrusion 65B side of the recess 66 of the lock member 61, so that the protrusion 127 of the safety stopper 111 is pressed and pushed out of the recess 66 of the lock member 61. The locking portion 123 moves within the window portion 125 of the lock member 61, the distance between the locking portion 123 and the pin 64 that is the rotation center of the lock member 61 is shortened, and the lock member 61 is centered on the pin 64. The locking member 123 of the safety stopper 111 does not come into contact with the protrusion 131 even when the protrusion 131 is rotated, so that the lock member 61 can freely rotate.

  Thereafter, when the hand is released from the pipe, the winding member 42 is rotated in the winding direction of the pipe 32 by the biasing force of the torsion coil spring (opening operation assisting member) 46, and the wire 48 is wound around the bevel 47. Going, this raises the lowermost pipe 32. When the lowermost pipe 32 is raised, the second protrusion 65A on the upper side of the lock member 61 is pushed upward, and the lock member 61 is on the side opposite to the guide groove 23 of the guide rail 21 (counterclockwise in FIG. 14). Direction) about the pin 64. At this time, the locking member 61 is given a force to rotate by the urging force of the tension coil spring 69. This rotational movement of the lock member 61 is transmitted to the interlocking member 101 by the link piece 102, and the interlocking member 101 linearly moves downward. The downward linear movement of the interlocking member 101 is transmitted to the closing member 81 by the link pieces 104, 104, and the closing member 81 moves horizontally to the side opposite to the guide groove 23 of the guide rail 21 to open the guide groove 23. The part is opened and each pipe 32 can be freely raised, and each pipe 32 is wound around the winding member 42.

  Even in the thus configured surface lattice 20, the surface lattice 20 is installed on the indoor side of the window sash 1, so that the surface lattice does not protrude outside the window and the appearance of the window portion is aesthetically pleasing. In addition, since the closing member 81 that closes the opening of the guide groove 23 of the guide rail 21 when the surface lattice 20 is closed is provided, a screw or a member that moves the lattice member 32 in the guide rail 21 is provided. Therefore, even when the window sash 1 is opened from the outdoor side, it is possible to prevent the surface lattice 20 from being opened, which is effective for crime prevention.

  Further, in order to close the surface lattice 20, when the lattice member 32 is fed out from the winding member 42 in the box 41 and the lattice member 32 is lowered along the guide groove 23 of the guide rail 21, the lattice member at the tip end 32 pushes the first protrusion 65B of the lock member 61 downward to rotate the lock member. As the lock member rotates, the closing member 71 moves to the guide groove 23 side of the guide rail 21. Since the opening of the guide groove is closed, the closing operation of the closing member 81 can be easily performed.

  Furthermore, even if the engagement between the stopper 67 and the lock member 61 is released, the safety stopper 111 prevents the lock member 61 from rotating, so that the pipe 32 is still restrained by the lock member 61, so that the torsion coil spring The grid member is not immediately moved by the urging force of 46, and it is safe, and the operator can release the prevention of the rotation of the lock member 61 of the safety stopper 11 only by pushing down the grid member 32 slightly. Since the grid can be opened, the operation is simple.

  9 to 11 may be provided with a safety device using the safety stopper 111, the protrusion 131, etc. shown in FIGS.

However, as shown in FIGS. 18 and 19, the surface lattice 20 is installed on the wall surface of the room. May be. If it does in this way, there is an advantage which does not narrow opening K.

  In the above-described embodiment, the lattice member 32 is completely accommodated in the blindfold 41. However, the entire lattice member 32 is not necessarily accommodated, and a part of the lattice member may be accommodated. . Moreover, the blindfolded part 41 does not need to be formed in a box shape, and it is sufficient if the lattice member is hidden.

  In the above-described embodiment, the lattice member 32 is moved in the vertical direction. However, the present invention is not limited to this, and the lattice member 32 may be moved in the horizontal direction. Furthermore, when the opening is formed obliquely, a blindfold may be provided along one side of the opening and moved toward the blindfold.

  Moreover, for example, a rod-shaped member or the like can be used as the lattice member, and a cylindrical member can also be used for weight reduction. The lattice member can be stored in the blindfolded portion by winding the lattice member around the winding member, or the lattice members can be stored in close contact with each other, or can be folded and stored. It does n’t matter how you do it. The blindfold may be provided adjacent to one end of the guide rail, or one end portion of the guide rail may be used as the blindfold. The connecting member may be a linear member such as a wire, or may be a plate-like member, for example. In addition, the connecting member may connect adjacent lattice members so as to be accessible, or may simply connect them.

  In the above-described embodiment, the torsion coil spring (biasing member) 46 is provided between the winding member 42 and the shaft 43 as an opening operation assisting member that assists the winding (opening operation) of the winding member 42. However, instead of this, a mainspring spring or a constant load spring may be used. When a constant load spring is used, the load can be made almost constant regardless of the stroke. Two such constant load springs may be used.
