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.

  Needless to say, the present invention is not limited to the above-described embodiments, and can be variously modified without departing from the scope of the invention. For example, in the above-described embodiment, the wires 36 and 36 are used as connecting members for connecting adjacent pipes (lattice members) 32, but instead of this, as shown in FIG. Adjacent lattice members 32 may be connected to each other using a connecting member 36a. That is, the insertion portion 33a at the end of the lattice member 32 is provided with a slit penetrating in the vertical direction, and the plate 36a is inserted into the slit. A protrusion-like locking portion 36b is provided at the lower end of the plate 36a, and the insertion portion 33a is hooked on the locking portion 36b when the plate 36a is lowered. The lower end of the plate 36a is bent obliquely outward to be provided with an inclined portion 36c. The upper end portion of the plate 36a is fixed to the insertion portion 33a of the adjacent upper lattice member 32.

  Thereby, while maintaining the space | interval between the lower insertion part 33a and the upper insertion part 33a constant, when the lower insertion part 33a approaches the upper insertion part 33a, it is controlled by the plate 36a. The lower insertion portion 33a can be raised freely without any problem. In other words, the spacing between the adjacent lattice members 32 and 32 is kept constant, and the lower lattice member 32 can freely move up and approach the upper lattice member 32 without being restricted by the plate 36a. It has become. Since the inclined portion 36c is provided, even if the end of the insertion portion 33a hits the plate 36a when the insertion portion 33a moves up, the plate 36a escapes outward, so that the upward movement of the insertion portion 33a is not hindered. .

  Further, as shown in FIG. 13, as the connecting member, adjacent lattice members 32 may be connected to each other by using a pantograph type link mechanism 36f. When the lattice members 32 are connected using links in this way, the distance between adjacent lattice members 32 moves in the same manner at any location, and therefore, the lattice members 32 become narrower or wider at the same interval. Further, in the case of a surface lattice using a link mechanism, the lattice member 32 is not wound up, but is provided along one side of the opening of the building with the distance in the moving direction of the lattice member 32 as close as possible. A part of the lattice member 32 is accommodated in the blindfold. If it does in this way, since the load at the time of the movement of the lattice member 32 does not change, it can be moved with good balance.

  In the above-described embodiment, the wire 48 is used as a pulling member (moving means) for pulling up the lattice member 32. Instead, a ball screw 48a may be used as shown in FIG. . In other words, the nut portion (slider) 48b may be connected to the end portion of the lattice member 32, and the screw shaft 48c may be rotated so that the nut portion 48b moves on the screw shaft 48.

  Further, as shown in FIG. 15, a strip-shaped plate 48f made of steel or the like that moves by means of winding or the like is provided as a drawing member of the lattice member 32, and a guide portion 48g provided on the plate 48f is provided with a lattice member. You may make it attach the edge part of the lattice member provided in the lower side, or the base board 32a, and move this along the guide groove 48h.

  Further, as means for moving the lattice member, a pinion may be fixed to the end of the lattice member and the pinion may be moved by a rack, or the lattice member may be connected to a predetermined portion of the belt, and the belt may be connected to the pulley. It is also possible to move the chain by rotating the sprocket or by connecting a lattice member to a predetermined part of the chain and rotating the sprocket.

  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 auxiliary mechanism for assisting winding of the winding member 42. Instead, 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.

  Further, as the interlocking mechanism between the locking device R and the closing member 81 for preventing the lattice member 32 from moving toward the blindfold 41 when the surface lattice 20 is closed, for example, a structure as shown in FIGS. You can also. 16 to 18, the same components as those in FIGS. 9 to 11 are denoted by the same reference numerals, and the description thereof is omitted or simplified.

  As shown in FIGS. 16 to 18, the configuration of the lock member 61, the stopper 67, the disengagement member 75 using the key 74, the closing member 81, etc. is the same as the configuration shown in FIGS. 9 to 11. In this example, 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 103 provided on 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.

  Accordingly, as the lock member 61 rotates about the pin 64 toward the guide groove 23 side (clockwise direction) of the guide rail 21, this rotational movement is transmitted to the interlocking member 101 by the link piece 102, and the interlocking member 101 is moved upward. Move straight to. This upward 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 toward the guide groove to close the opening of the guide groove 23.

  On the other hand, when the surface lattice 20 is opened, if the lock member 61 rotates about the pin 64 on the opposite side to the guide groove 23 of the guide rail 21 (counterclockwise in FIG. 18), this rotational movement is caused by the link piece 102. Is transmitted to the interlocking member 101, 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.

  As shown in FIGS. 19 and 20, guides 108 (upper and lower in this example) made of synthetic resin such as POM (Duracon) are attached to the interlocking member 101, and the guides 108 are guide parts 103 of the guide rails 21. The interlocking member 101 moves smoothly up and down. In this way, it is possible to prevent the interlocking member 101 from being caught by the guide portion 103 and twisting the interlocking member 103, and to reduce wear of the interlocking member 101 and the guide portion 103.

  In the above-described embodiment, the locking device R that prevents the lattice member 32 from moving toward the blindfold 41 when the surface lattice 20 is closed is automatically performed as the lattice member 32 is lowered, and the lattice of the locking device R is further reduced. Although the movement preventing operation of the member 32 and the closing operation of the closing member 81 are interlocked, this may be performed manually. That is, for example, as shown in FIGS. 21 and 22, one end of an interlocking member 101 that can be moved up and down is connected to an operation link piece 111 that is rotated by a key 74. Are connected by L-shaped plate-like link pieces 114 and 114 at two upper and lower positions, respectively, and after this, the lattice member 32 is lowered, and then the key 74 is manually turned to turn the closing member 81 into the guide groove of the guide rail 21. 23, the opening of the guide groove 23 may be closed, and the movement of the lattice member 32 may be blocked by the recess 96 of the closing member 81.

  Further, as a lock device that prevents the lattice member 32 from moving toward the blindfold 41 when the surface lattice 20 is closed, for example, the lock member 61 is manually rotated using a key to restrain the lattice member. You may comprise. Further, as shown in FIG. 23, a lock member 61 is provided on a crosspiece (horizontal member) 116 provided at the lowermost position on the lower side of the lattice member 32, and this is manually rotated using a key to be locked. You may make it do. Further, when the lateral member 116 is provided with an interlocking mechanism such as a combination of a cylinder and a link mechanism so that the left and right lock members 61 and 61 are operated in conjunction with each other, the left and right lock members can be operated with one key. The operation can be performed, and the trouble of closing the face grid can be saved.

  As shown in FIG. 24, insertion portions 33h provided at both ends of a pipe (lattice member) 32 are circularly formed on a large-diameter head 33i, a neck 33j thinner than the head 33i, and a tip of the neck 33j. With an enlarged fixing portion 33k, the head 33i is disposed on the guide rail 21 side, while the neck portion 33j is inserted into the end of the pipe 32, and a screw penetrating the fixing portion 33k and the pipe 32 is used. The insertion portion 33h is attached to the pipe 32. As described above, since the outer diameter of the neck portion 33j inserted into the pipe 32 is reduced and a gap is provided between the inner diameter of the pipe 32, the pipe 32 is largely inclined by α degrees with respect to the insertion portion 33h. The tip of the neck 33j does not contact the inner surface of the pipe 32. Therefore, even if the pipe 32 is moved to be detached from the insertion portion 33h and the pipe 32 is slightly inclined with respect to the insertion portion 33h, the tip portion of the neck portion 33j does not come into contact with the inner surface of the pipe 32. It can be prevented from being damaged, and is effective in crime prevention measures. The insertion portion 33h is made of zinc die casting or the like, and is made of a stainless steel pipe of the pipe 32 or the like. A bar 121 made of aluminum or the like is inserted into the pipe 32, thereby preventing crimes from being easily cut, thereby enhancing the crime prevention effect.

FIGS. 25 to 28 show examples of the connecting structure between the cylindrical members 123 and 123 and the bevel wheels 47 and 47, which are rotatably fitted to the outer sides of both ends of the shaft 43 and to which the winding member 42 is fixed. FIG.
As shown in FIG. 25, the torsion coil spring (biasing member) 46 is provided as an auxiliary mechanism that assists in winding the winding member 42. That is, the torsion coil spring 46 is provided between the one cylindrical member 123 and the shaft 43 fixed between the left and right side plates of the box 41, and elastically deforms when the lattice member 32 is extended, As a result, the winding member 42 urges the pipe 32 in the winding direction to rotate the winding member 42 in the winding direction.

  Since the spring 46 has a weak elastic force with repeated use, it may be necessary to adjust the number of turns. At this time, it is necessary to separate the bevel wheel 47 around which the wire 48 is wound so as not to rotate together with the wind-up member 42. However, if the bevel wheel 47 is fixed to the cylindrical member 44 with a screw or the like. It is not easy to remove the screw, and the adjustment of the number of turns of the spring 46 is not easy.

Gear-shaped fitting recesses 132 and 132 and grooves 133 and 133 are alternately formed in the inner peripheral portion of the shaft portion 131 of the bevel wheel 47, and the insertion portion 125 of the tubular member 123 is pivoted from the shaft portion 131 of the bevel wheel 47. By slightly moving in the direction, the cylindrical member 123 can be rotated with respect to the bevel wheel 47. That is, as shown in FIG. 27, in a state where the insertion portion 125 of the cylindrical member 123 is inserted into the shaft portion 131 of the bevel 47, the fitting protrusions 124 and 124 are fitted into the fitting recesses 132 and 132, respectively. Thereby, the cylindrical member 123 and the bevel wheel 47 rotate together. On the other hand, as shown in FIG. 28, when the insertion portion 125 of the tubular member 123 is slightly extracted from the shaft portion 131 of the bevel wheel 47, the fitting convex portion 124 on the distal end side of the tubular member 123 is the groove portion 133 of the bevel wheel 47. And the base-side fitting convex portion 124 is located outside the shaft portion 131, whereby the cylindrical member 123 is rotatable with respect to the bevel wheel 47. Further, in a state where the insertion portion 125 of the cylindrical member 123 is pushed into the shaft portion 131 of the bevel wheel 47 rather than the state of FIG. 27, the fitting convex portions 124 and 124 of the cylindrical member 123 are the groove portions 133 and 133 of the bevel wheel 47, respectively. Thus, the cylindrical member 123 is rotatable with respect to the bevel wheel 47.

Therefore, in FIG. 25, when the cylindrical members 123, 123 on both sides connected via the winding member 42 are moved slightly to the left, the cylindrical members 123, 123 are respectively moved with respect to the bevels 47, 47. The winding member 42 and the two cylindrical members 123, 123 that are integrated in this state can be rotated to adjust the winding number of the spring 46. As shown in FIG. 25, a gap is provided between the right cylinder member 123 and the screw 135 fixing the spring 46 to the shaft 43 so that the cylinder member 123 can be moved to the left side. (Play) t is provided.
As described above, when the cylindrical member 123 to which the winding member 42 is attached and the bevel 47 are connected by the connecting portion that is in the fitted state and the released state by the axial movement operation of the cylindrical member, the winding is performed. It is possible to easily adjust the elastic force of a spring (biasing member) 46 as a winding assist mechanism (opening / closing assist mechanism) for assisting the winding of the member 42.

  Also, as shown in FIG. 29, if the tip surfaces 137, 137 of the bevels 47, 47 on both sides are brought into contact with the inner surface 41a of the box 41, the left and right positioning as shown in FIG. Therefore, the washer 138 and the split pin 139 are not required.
