    The support stick is provided between the summing fence of the movable inner shoji (hereinafter referred to as the inner shoji) and the outer shoji frame of the sliding shoji and one-sided shoji. The position where the sticker is provided is placed on the lower frame of the opening frame along the lower arm of the sliding shoji and the outer shoji (1). It is better not to install it obliquely from the viewpoint of crime prevention, but to provide it on the lower frame between the lower arm of the shoji and the window base on the inner side of the lower frame of the opening frame. This is because the glass near the crescent that locks the internal and external shoji is usually broken by an intruder, and if the stick is tilted, it is easily removed by placing the hand on the stick.

    It is difficult to remove if the stick is dropped into the groove between the window sill and the lower arm of the shoji. In particular, when a stick is inserted obliquely near the horizon and pushed in, a great horizontal force acts between the shoji of the inner shoji and the outer shoji, which is convenient for crime prevention but difficult to remove. Therefore, in the case of a stick, if it is placed between the window sill and the shoji, both ends should be provided with a little sump for the summon bowl and the outer shoji. Then the thief may detect this and remove it.

The groove 3j may be the mounting portion. Further, the entire width between the window sill 3h and the external shoji 7 may be used as a mounting part, and the stick 21 may be disposed on the rail 3b. That is, the mounting portion is selected mainly by the lower frame of the opening frame and the shape around the window frame.

    Next, each part will be described in detail.

(Door-to-door member)
The door contact member 22 is made of rubber, a relatively elastic synthetic resin elastomer or the like. As shown in FIG. 6, the door stop member 22 has a mounting cone shape having a center line in the direction of finding (lateral direction along the wall surface). The top of the door stop member 22 has a hole 22a, an end face 22b, and a hole bottom 22c. The door contact member 22 is a member that faces the direction in which the tapping screw 22f inserted into the screw hole further provided from the hole bottom 22c faces the direction of the summoning rod 12 of the inner shoji 6 (the lateral direction along the wall surface). It is screwed and fixed to the lower end of the material 12b.

(Meeting contact part for door-to-door contact)
A screw member 23 having a fitting portion 23a1 loosely fitted in the hole 22a of the door stop member 22 is provided on the side of the sticking rod 21 with respect to the door stop member 22. The screw member 23 is screwed into the end of the length adjusting rod 27. The end portion of the length adjusting rod 27 forms a contact portion 23a2 of the door-to-door contact member fitting contact portion 23a. The mating portion 23a1 and the abutting portion 23a2 together constitute a door-to-door member fitting abutting portion 23a. The hole 22a and the fitting portion 23a1 are provided with a dimensional difference so that the fitting rod 21 can be fitted with the coil spring 24 side up even if the fitting rod 21 is greatly inclined, for example, about 45 degrees. The fitting portion 23a1 may be tapered so that the mouth side of the hole 22a is large and the hole bottom diameter is small and conical.

(Length adjustment rod)
The length adjusting rod 27 is a round bar having a plurality of steps and sequentially reducing the diameter from the door stop side. The length adjusting rod 27 has a screw 27b at the left end in FIG. The male screw 27b is screwed into the nut 34 so that the position in the longitudinal direction can be adjusted. The length adjusting rod 27 is provided with a two-surface width portion 27c on which a spanner can be hung.

(First spring support member)
The first spring support member 26 includes a screw member 23, a cylindrical tube 25, a nut 34, and a length adjustment rod 27. Then, by adjusting the longitudinal position of the length adjusting rod 27 with respect to the nut 34, the length of the first spring support member 26 is adjusted, and the total length of the support rod 21 is changed.

(Cylindrical tube 25)
The nut 34 described above is fixed to one end of the cylindrical tube 25. In this fixing method, the nut 34 is press-fitted into the cylindrical tube 25. Alternatively, the nut 34 is inserted into the cylindrical tube 25 and the cylindrical tube 25 is caulked toward the nut 34. Or press-fit and use both. The nut 34 and the cylindrical tube 25 may be welded. One end of a coil spring 24 is fixed to the cylindrical portion 25 a at the other end of the cylindrical tube 25. In this fixing method, the outer diameter of the coil spring 24 is made larger than the inner diameter of the cylindrical portion 25a, and the coil spring 24 is inserted into the cylindrical portion 25a with the diameter reduced by twisting, or the twist is released. Or just press fit.

(Coil spring)
The coil springs 24 are made at the same pitch as that of the wire having a circular cross section, or at a pitch larger than the diameter of the wire by a minute dimension. The coil spring 24 can be fixed to the cylindrical portion 25a and the cylindrical tube 28 having the same diameter as the cylindrical portion 25a by the above-described method. In this example, the spring force of the coil spring 24 is about 8 kg, and the cylindrical tube 25 pulls the central portion of the coil spring 24 perpendicularly to the support rod 21 in the longitudinal direction. , 28 are about 30 degrees with respect to the horizontal line.

(Second spring support member)
The second spring support member 30 includes a cylindrical tube 28 having a cylindrical portion 28a and a top 31 having a door-to-door-side fitting contact portion 31a.

(Cylindrical tube 28)
The other end side of the coil spring 24 described above is fixed to one end of the cylindrical tube 28. Since this fixing method is the same as the fixing method of the one end side 24a of the solid coil spring 24 and the cylindrical portion 25a, description thereof will be omitted.

A top 31 is fixed to the other end of the cylindrical tube 28. In this fixing method, the fixing portion 31b is press-fitted or caulked into the cylindrical tube 28, or both. Alternatively, the top 31 may be fitted into the cylindrical tube 28 and welded.
The top 31 is provided with a mating contact portion 31a on the side opposite to the door. The fitting contact portion 31a has a protruding fitting portion 31a1 and a contact portion 31a2 which is an end face of the fixed portion 31b of the top 31. The fitting portion 31a1 has a root at a portion that continues to the contact portion 31a2, and has a taper that tapers from the root toward the tip. The base of the fitting portion 31a1 is sized to fit loosely into the hole 29b of the bracket 29. The abutting portion 31a2 is a conical protrusion. The apex angle of this cone is large. Since the conical apex angle of the abutting portion 31a2 is large, the second spring support member is fitted in the state in which the fitting portion 31a1 is fitted in the hole 29b facing the horizontal direction of the bracket 29 when the contact portion 31a2 is moved by the action described later. Even if the center line of the counter-door-side fitting contact portion 31a intersects the center line of the hole 29b of the bracket 29 with the tilt of the cylindrical tube 28, which is a component of 30, the contact portion 31a2 is the edge of the hole 29b. The bracket 29 contacts the stopper portion 29c. Thereby, engagement / disengagement with the 2nd spring support member 30 with respect to the bracket 29 is made smooth.
The screw member 23, the length adjusting member 27, the cylindrical tube 25, the coil spring 24, the cylindrical tube 28, and the top 31 described above have a center line in a straight line in a natural state (a free state in which no external force is applied).

(Operation member)
As shown in FIGS. 4 and 7, an operation member 32 is fixed to the cylindrical tube 28. The operation member 32 is disposed substantially along the longitudinal direction of the coil spring 24 from the position a fixed to the cylindrical tube 28 toward the right in FIG. When using the stick 21, the operating member 32 is at the top.

    As shown in FIG. 7, the one end 32 a of the operation member 32 is formed in the shape of a circle along the circumferential direction of the cylindrical tube 28 and goes around the lower side of the cylindrical tube 28. The one end 32 a is fixedly fixed to the cylindrical tube 28 by installing a blind rivet 35 in a hole at the one end 32 a and a hole penetrating in the radial direction of the cylindrical tube 28.

    The operation member 32 is provided with a spring holding piece 32c having the same shape as the one end 32a so as to hold the coil spring 24. The cross-sectional shape perpendicular to the longitudinal direction of the connecting rod 21 of the spring holding piece 32c is substantially the same as the one end 32a shown in FIG.

    The other end 32b of the operation member 32 is bent upward so as to be easily hooked with a finger and serves as a handle.

    Except for the one end 32a and the spring holding piece 32c described above, the cross section perpendicular to the longitudinal direction of the operation member 32 has an arc shape with a central angle of about 90 degrees.

    The spring holding piece portion 32 c of the operation member 32 is at substantially the center in the longitudinal direction of the coil spring 24. Therefore, the force for bending the coil spring 24 can be selected by selecting the length from the spring holding piece 32c to the other end 32b serving as a handle. A lock 37 may be provided on the operation member 32. When the key is rotated downward from above to the lock 37, the external screw in the lock 37 rotates and descends and is screwed into the female screw 25b (see FIG. 6) provided in the cylindrical tube 25.

(bracket)
As shown in FIGS. 2 and 3, the base 29 a of the bracket 29 is in contact with and fixed to the lower heel 16 or the door-to-door ridge 17 of the pelvis 7 between the pelvis 7 and the guide rail 3 b. As a fixing method, a screw member (not shown) is inserted into the lower rod 16 or the door rod 17 (not shown) through a hole 29d provided in the base 29a. Alternatively, a hole having the same diameter as the hole 29d is formed in the hole 29d and the lower rod 16 or the door stopper rod 17 at the same position as the hole 29d, and these holes are used to fix the holes with blind rivets.

    As shown in FIG. 6, the bracket 29 is L-shaped when viewed from above, and the stopper 29c bent from the base 29a is a hole into which the fitting part 31a1 of the counter-door-side fitting contact part 31a is fitted. 29b is provided. The hole 29b has a size that allows the fitting portion 31a1 to be loosely fitted.

(Function)
As shown in FIGS. 2, 4, 5, and 6, the stick 21 is straight when no external force is applied. A door-to-door member 22 is fixed to the summoning bowl 12. A bracket 29 is fixed to the lower rod 16 or the door rod 17. It is assumed that the stick 21 is removed from the mounting portion S between the door stop member 22 and the bracket 29.

    When starting use of the stick 21, the length of the stick 21 is adjusted with respect to the distance L between the stopper portion 29 c of the bracket 29 and the end face 22 b of the door stop member 22. The length of the support rod 21 is adjusted by adjusting the screwing amount of the length adjustment rod 27 into the nut 34. Then, the distance between the end face (impact portion 23a2) of the collar 27d of the stick 21 and the end face (impact portion 31a2) of the top 31 is made to correspond to the distance L.

    Then, as shown in FIG. 8, the coil spring 24 is bent by holding the handle on the other end 32 b side of the operation member 32 and the first spring support member 26. As a result, the length between the top of the screw member 23 of the connecting rod 21 and the tip of the fitting portion 31a1 of the top 31, that is, the length δ of the bending of the connecting rod 21 is shorter than the distance L. In this state, the support rod 21 is inserted between the door stop member 22 and the bracket 29 so that the fitting portion 23a1 at one end matches the hole 22a of the door stop member 22 and the fitting portion 31a1 at the other end is bracketed. It is made to correspond to the 29 holes 29b. Next, when the handle which is the other end 32b of the operation member 32 and the hand holding the first spring support member 26 are loosened to loosen the curvature of the coil spring 24, the fitting portion 23a1 at one end becomes the door. The contact member 22 is inserted into the hole 22a. The other end fitting portion 31 a 1 is inserted into the hole 29 b of the bracket 29. And if the force which is going to bend the coil spring 24 from both hands which have the handle (32b) and the 1st spring support member 26 is removed, the coil spring 24 will become straight. At this time, if the fitting portion 31 a 1 is first fitted into the hole 29 b of the bracket 29, attachment is easy. At this time, the fitting portion 23 a 1 at one end completely enters the hole 22 a of the door stop member 22, and the contact portion 23 a 2 contacts the end surface 22 b of the door stop member 22. Similarly, the fitting portion 31 a 1 at the other end completely enters the hole 29 b of the bracket 29, and the abutting portion 31 a 2 contacts the stopper portion 29 c of the bracket 29.

    In addition to the above, the coil spring 24 may be bent and attached after one end of the stick 21 is fitted into the door stop member 22 or the bracket 29.

    Here, assuming that the distance between the contact portions 23a2 and 31a2 of the support rod 21 is greater than the length L, the force that the contact portion 23a2 hits the door stop member 22 and the contact portion 31a2 are applied to the bracket 29. The hitting force is equal. To adjust this force, the operation member 32 side of the stick 21 is held by hand and a spanner is applied to the two-sided width portion 27c of the length adjustment rod 27 to rotate. Since the distance between the abutting portions 23a2 and 31a2 is limited to L, when the length adjusting rod 27 is rotated, if there is a gap between the coil spring lines, the amount of compression deflection of the coil spring 24 changes. Therefore, the summoning rod 12 of the inner shroud 6 is pressurized in a direction to close the inner shroud 6 on the basis of the mounting position of the bracket 29 to the outer shoji 7. When the stick 21 presses the door stop member 22, the door stop member 22 is elastic and thus compressed. Further, the distance L between the contact portions 23a2 and 31a2 may be made smaller. However, it is limited to the range in which the stick 21 is not detached from the door stop member 22 and the bracket 29.

    After the adjustment of the length of the stick 21 is completed, the stick 21 is detachably mounted on the mounting portion S of the lower frame 3 between the bracket 29 and the door stop member 22.

  In order to remove the straight stick 21 between the door stop member 22 and the bracket 29, the operation member 32 may be lifted by holding the handle on the other end 32b side. When the handle is lifted, the coil spring 24 is strengthened and the radius of curvature is reduced.

    At this time, the fitting portion 23a1 at the head of the screw member 23 decreases the degree of fitting into the hole 22a of the door stop member 22. Further, the fitting portion 31a1 that is the protrusion of the top 31 reduces the insertion depth of the bracket 29 into the hole 29b. Then, the fitting portion 23a1 of the screw member 23 is removed from the hole 22a of the door stop member 22, or the fitting portion 31a1 of the top 31 is removed from the hole 29b of the bracket 29, so that one end of the connecting rod 21 is restrained. When the hand is loosened after being unwound, the coil spring 24 is restored straight and the stiff bar 21 becomes straight. In the state where the handle is lifted and the coil spring 24 is curved in the above, a space is formed between the coil spring 24 and the lower frame 3. By supporting the coil spring 24 portion with a finger or the like from this space, the hole of the door contact member 22 is formed. It is possible to select whether the fitting portion 23a1 of the screw member 23 is removed first from 22a or the paired opening fitting portion 31a1 which is the projection of the top 31 is removed first from the hole 29d of the bracket 29.

    In addition, partial opening of the inner impeller 6 is realizable by making the space | interval of the door stop member 22 and the bracket 29 larger than the length of the connecting rod 21. FIG. That is, the distance L is set larger than the distance between the contact portions 23a2 and 31a2 of the connecting rod 21. Moreover, also in the said Example, the partial opening of the inner impeller 6 is realizable by adjusting the screwing amount to the nut 34 of the length adjustment rod 27. FIG.

    In the above, if the length of the stick 21 is adjusted initially, it is not necessary to adjust it every time it is used. The attachment of the support rod 21 to the mounting portion S is performed by bending the coil spring 24 using the operation member 32.

    To remove the support rod 21 from the mounting portion S, the coil spring 24 is bent using the operation member 32 and removed. Thus, since the coil spring 24 or the elastic force of the door stop member 22 or the elastic force of the both is held along the lower frame 3, the inner shoji 6 is closed without any force and is pushed by the spring force. Even if the burglar destroys the crescent and vibrates the inner shoji 6, it remains closed without rattling. And even if the burglar finds the stick 21 that is hard to intrude, it is difficult to find out how to remove it because the mounting portion S is in the narrow groove of the lower heel 16 of the shoji 7 and the window base 3h of the lower frame 3. Usually, the stick is lifted up and removed, so if it is attempted to lift the adjustment rod 27 with any tool, it cannot be lifted by the fitting of the door stop member 22 and the screw member 23. In particular, when the lock 37 is locked, the very sticky bar becomes an integral bar and cannot be lifted. Even if the cylindrical tube 28 of the second spring support member 30 is to be lifted, the bracket 29 and the top 31 are engaged and cannot be lifted. Since the coil spring 24 is covered with the operation member 32 when viewed from above, the coil spring 24 is difficult to find.

    In the above-described embodiment, when the inner shroud 6 is opened with the support stick 21 removed from the mounting portion S, the door-contact member 22 of the inner shroud 6 hits the bracket 29 and the inner shunt 6 is partially opened.

    Further, when the length adjusting rod 27 is screwed into the nut 34 and the length of the sticking rod 21 is shortened, the inner shoji 6 can be partially opened so that a person cannot enter and exit.

    When the length of the stick rod 21 is short, an extension rod rod 36 shown in FIG. The rod rod 36 of a round bar has a fitting contact portion having a fitting portion 23a1 loosely fitted in the hole 22a of the door contact member 22 and an contact portion 23a2 in contact with the hole bottom 22c of the door contact member 22 at one end. 23a. The other end of the round rod rod 36 is provided with a male screw 36a.

    The extension rod rod 36 removes the screw member 23 from the length adjustment rod 27, and the screw member 23 is screwed in, so the screw 36a is screwed and fixed to the screw 27e. When the extension rod rod 36 is used, the bracket 29 is fixed to the door-to-door rod 17 which is a rod at the edge of the rigid frame 5.

    When the support rod 21 using the extension rod rod 36 is removed from the mounting portion S, the inner impeller 6 can be almost fully opened.
