Field of the Invention The present invention relates to a rail piece suspended from a window upper frame and an engaging groove provided on a sliding door frame, and the rail piece is engaged with the rail piece. The present invention relates to a device for preventing a sliding door moving along a sliding door. 2. Description of the Related Art Sliding door sashes which move along the rail pieces by engaging rail pieces suspended from a window upper frame with engagement grooves provided in a sash upper frame are required. In general, when removing from the window frame, it is performed using a kendon method. For example, when the kendon method is locked in a mutual relation between the inner and outer sashes like a sliding sash, the inner and outer sashes are removed. In some cases, the sliding door may be removed by performing the removing operation at the same time, which is not preferable for crime prevention. [0003] For this reason, a restrictor is screwed to the window upper frame side to restrict the rise of the shoji, so that the shoji cannot be removed. [0004] The above conventional example is structurally
Although it is possible to reliably control the removal of the shoji from the window frame by the stub operation, there is an inconvenience that the regulator must be removed one by one to remove the shoji when necessary. The present invention has been devised in view of the drawbacks of the conventional example in order to provide a novel structure of a shoji slip-preventing device. [0006] In a shoji that moves along the rail piece by engaging a rail piece suspended from the window upper frame and an engaging groove provided in the shoji upper frame with each other, A pair of opposing support pieces are erected on the base of the stopper body screwed to the bottom wall of the mating groove with an engagement gap with which the rail pieces engage with the ascending operation of the sash. A restricting piece is fitted to the supporting piece so that the fitting piece is fitted to the supporting piece so as to be able to adjust the rotation angle from the outside of the engaging groove, and the restricting piece is attached to the pair of fitting pieces. The fitting pieces are connected to each other at an eccentric position of the rotation axis to form a regulating piece that closes the engagement gap. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a longitudinal sectional view, FIG. 2 is a transverse sectional view of FIG.
3 is a cross-sectional view taken along the line XX of FIG. 2, FIG. 4 is a cross-sectional view taken along the line YY of FIG. 2, and FIG. 5 is a schematic front view showing an arrangement position of the stopper. In the embodiment, a rail piece 2 is hung on an upper frame 1 of a window frame F, and the rail piece 2 and an engaging groove 4 provided in the upper frame are engaged with each other so that the inner and outer shojis are engaged. B, B 'are assembled to the window frame F, and the upper frame 3 of the outer shoji (hereinafter simply referred to as shoji) B
The stopper A is attached to the window frame F to prevent the sliding door B from coming off the window frame F by the contact relation between the stopper A and the rail piece 2 of the window upper frame 1. It is not necessary to limit only to the sliding sash as in the example. The release stopper A comprises a stopper main body 5 and a regulating piece 6 attached to the stopper main body 5, and the stopper main body 5 is provided on the bottom wall 4a of the engaging groove 4 of the upper frame 3. The rail piece 2 is located immediately below the base 7 and the rail piece 2 secured by the screw 12.
Are formed with a pair of indoor and outdoor support pieces 9 and 9A erected on the base 7 with an engagement gap 8 for engagement. A circular support hole 10 is provided in one of the support pieces 9 on the indoor side constituting the stopper body 5, and the other support piece 9 is provided.
A is provided with a circular support portion 10A which is located on the same axis as the support hole 10 and has substantially the same diameter. The support portion 10A is provided on the other support piece 9A on the side opposite to the one support piece 9 as described above, and has a lower height than the support piece 9 like the support piece 9. A pair of elastic pieces 11 protruding in an arc shape at the upper end of the main body 9A '
The main body 9 is formed so that the inner peripheral surface thereof is continuous with the inner surface of the main body 9.
The semicircular recess 10A '(main part 9A') formed in A '
Is formed by recessing a portion corresponding to the support hole 10 in the outdoor direction), and the inner wall of the recess 10A 'forming the support portion 10A has the recess 10A'. An arc-shaped guide slot 13 is provided along the inner peripheral surface. Then, the restricting piece 6 is attached to the supporting portion 10A.
One of the fitting pieces 14A is rotatably engaged with the other fitting piece 14 of the regulating piece 6 in the support hole 10, and is connected between the fitting pieces 14, 14A. The restricting piece 15 is disposed at an eccentric position from the axis and is aligned with the engagement gap 8, while a protrusion 16 provided on the outdoor end face of one fitting piece 14 </ b> A is engaged with the guide slot 13. In addition, the regulating piece 6 is assembled to the apparatus main body 5 as described above. The regulating piece 6 has a peripheral end of one fitting piece 14 on the inner peripheral surface of the support hole 10 and another fitting piece 14.
A peripheral end of the contact portion A comes into contact with an inner peripheral surface of the support portion 10A so that the rotation is smoothly performed. The restriction piece 15 eccentrically arranged on the rotation axis includes a fitting piece 14, 14
At the peripheral end position of A, the rail pieces 2 are arranged along the rotation axis (the axis) to regulate the engagement of the rail pieces 2 with the engagement gaps 8 (that is, the rise of the shoji B). A position deviating from the position of the rotation axis, which is a line (in the eccentric position), moving from a low place to a high place by rotating the regulating piece 6 to regulate the engagement of the rail piece 2 into the engaging gap 8. It is good if it is arranged. The engagement between the projection 16 and the guide slot 13 is not always necessary for the embodiment of the present invention, but in the case of the embodiment, one end 13 'of the guide slot 13 is connected to the other end 13'.
By moving the projection 16 in the ″ direction (by rotating the regulation piece 6), it is regulated at an intermediate position on the other end 13 ″ side of the guide elongated hole 13 (by the cross-sectional shape of the regulation piece 15). Piece 15
Can be restricted with respect to the engagement gap 8 of the rail piece 2, and can be moved only between both ends of the guide slot 13 of the projection 16, so that unnecessary rotation operation of the restriction piece 6 is unnecessary. Can be prevented. In the embodiment, one fitting piece 14A of the regulating piece 6 is used.
Are formed in a gear shape, and a large number of receiving grooves 1 are formed in a circular peripheral end surface.
Are arranged side by side at equal intervals, and a locking ridge 18 provided on the inner surface of the distal end of the elastic piece 11 constituting the supporting portion 10A so as to be locked in an arbitrary receiving groove 17 is provided. Locking ridge 18
Are always engaged with one of the receiving grooves 17 so as to regulate the rotation of the regulating piece 6. However, the regulating piece 15 is engaged with the engaging gap 8 of the rail piece 2. Is moved to a position where the restricting piece 15 is moved from a low place to a high place, the moving position may be maintained. Groove 1
It is not necessary to provide 7, and only a pair of (or a single) receiving groove 17 may be engaged with the locking ridge 18 (only one may be provided) only when it moves to the regulation position. (Engagement of the locking ridge 18 with respect to the receiving groove 17 is performed by the elastic piece 11.
Is carried out by elastic deformation). Further, the means for maintaining the moving position does not need to be limited to the structure as in the embodiment. For example, the restricting piece 15 is formed in a rectangular cross section, and the base end is fixed to the base 7 on the outer peripheral surface. If the distal end side of the spring piece is pressed into contact, the movement of the restriction piece 15, that is, the rotation of the restriction piece 6, can be restricted, and the same function as in the embodiment can be expected. Further, in the embodiment, a window hole 20 for inserting a tool is provided in the indoor side wall 4b which is the upper frame part piece constituting the engaging groove 4 (the upper frame piece 3a overlapping the indoor side wall 4b is also provided). A receiving groove provided with a tool tip from the interior side of the fitting piece 14 of the regulating piece 6 from the indoor side through the window hole 20 (through the window hole 20A in the embodiment). When the engaging piece 14 is rotated by engaging with the engaging piece 21, the regulating piece 6 is rotated by the engaging relationship between the fitting piece 14 and the support hole 10 and the engaging relationship between the fitting piece 14A and the support portion 10A. As a result, the regulating piece 15 moves upward while rotating from the lower part of the engagement gap 8, and the protrusion 6 also moves along the guide slot 13 from one end 13 ′ to the other end 13 ″. Move, and by the rotation operation,
The state in which the restricting piece 15 has moved to the uppermost position (movement past it is, as described above,
''), And the state position is maintained in the engagement relationship between the locking ridge 18 and the receiving groove 17, and in this state, the engagement gap of the rail piece 2 is maintained. 8 to the engagement groove 4 is restricted from being engaged with the bottom wall 4a, and even if the shoji B is lifted by the steadily operation to be removed from the window frame F (upper frame 1), the shoji B does not rise. It will be regulated and will be removed. When the regulating piece 6 is rotated to the original position at the fitting piece 14 as necessary, the regulating piece 15 is retracted from the regulating position, and the rail piece 2 is moved from the engaging groove 4 to the engaging groove. The gap 82 is engaged, and the sliding door B can be removed from the window frame F by a stub operation. Since the present invention has the above-described configuration,
Regardless of the position of the sash with respect to the window frame, the engagement of the rail piece with the engagement groove of the rail piece up to the position where the sash can be raised can be restricted, and the sash can be prevented from being removed by the tentative operation. Since the engagement of the rail piece with the engagement gap is regulated by the regulation piece eccentric from the rotation axis of the fitting piece or the regulation piece, it is only necessary to rotate the fitting piece or the regulation piece. Since the regulation can be released, it is possible to perform the removal by a sword and to perform the operation without a complicated operation as required.
