Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
【Example】
FIGS. 1 and 2 show an example in which the present invention is applied to a glass support frame of a curtain wall. A glass support frame (2) is formed between left and right adjacent sets (1) and (1 ′), and the support frame (2) is formed. Of the left vertical frame (3) of the left vertical frame (3), the bottom wall portion facing the side end surface of the glass (5) in the glass fitting groove (4) having a filing margin. The glass movement restricting block (7) is rotatably supported at 6), and the restricting block rotation stopper (9) is supported by the outdoor bead fitting groove (8). (10) is an outdoor bead, (11) is an indoor bead fitting groove, and (12) is an indoor bead.
[0011]
The restricting block (7) has a relatively thick restricting portion (14) protruding from a relatively thin substrate (13) as shown in FIG. 4, and the substrate (13) has an axis at a key point. A substantially crescent-shaped restricting portion (14) formed in a sector shape having a hole (15) and having an arc-shaped side concentric with the arc-shaped side of the substrate (13) at a position near the arc-shaped side on the plate, The arc-shaped side protrudes from the substrate (13) so as to project slightly outward from the arc-shaped side. (16) is a through hole provided on one side of the substrate (13).
[0012]
The above-described shaft hole (7) is positioned so that the restricting block (7) can pass the restricting portion (14) toward the glass fitting groove (4) groove and under the outdoor bead fitting groove (8). In the present embodiment, the screw (17) and the nut (18) are fastened to the bottom wall (6) in a rotatable temporary holding state by a screw (17) and a nut (18).
[0013]
In this case, when the regulation part (14) is positioned behind the outdoor bead fitting groove (8) as shown in FIG. 3A by the rotation of the regulation block (7), the regulation part (14) 14) retreats to a position (glass movement allowable position) which deviates from the horizontal movement course of the glass (5), and rotates the regulation block (7) clockwise or counterclockwise from that position, as shown in FIG. If the straight side of the substrate (13) comes into contact with the step (19) in the chamber in the fitting groove (4) as shown in FIG. Takes a position (glass movement restriction position) within the horizontal movement course of the glass (5).
[0014]
The rotation stopper structure is as follows. First, a portion corresponding to the regulating block (7) of the outdoor bead fitting groove (8) having a U-shaped groove (8 ') with a lip in cross section is notched (P). As shown in FIG. 5, the rotation stopper (9) is a stopper body that bends an intermediate portion of a stainless steel plate having a width insertable into the groove (8 ′) of the bead fitting groove (8) into a U-shape. Arm plates (21) and (21) are formed at (20) and extend at right angles from both ends of the U-shape. In this embodiment, rubber is further provided in the U-shape of the stopper body (20). A square pillar-shaped filling piece (22) made of an elastic material such as a synthetic resin is fitted and bonded.
[0015]
The two arm plates (21) and (21) of the rotation stopper (9) as described above are inserted into the groove (8 ') of the bead fitting groove (8) from the cutout in the depth direction of the groove (8'). The stopper body (20) is displaceably inserted and the stopper block (7) is positioned in the notch (P) so that the restriction block (7) can move forward and backward.
[0016]
In this case, when the two arm plates (21) and (21) are in contact with the lip in the groove (8 '), the stopper body (20) is elastically moved deeper than the rear surface of the fitting groove (8). When the regulating block (7) is in the glass movement allowable position as shown in FIG. 3A, the stopper body (20) prevents the regulating portion (14) from moving forward. While being elastically pressed against the outer surface of the restricting portion (14). In this embodiment, the temporary holding of the restriction block (7) is performed by using both the screw (17) and the nut (18) that support the restriction block (7) and the press-contact of the stopper body (20). Is going.
[0017]
When the regulating block (7) is at the glass movement regulating position, the regulating portion (14) separates from the pressure contact with the stopper main body (20), and allows the stopper main body (20) to move forward. When the restricting block (7) is rotated to the glass movement restricting position, the stopper body (20) is automatically moved to a position near the end of the restricting portion (14) deeper than the outer surface of the restricting portion (14) due to its elastic force. , Thus locking the restriction block (7) so that it cannot rotate.
[0018]
Since the glass fitting groove (4 ') of the other vertical frame (3') in the glass supporting frame (2) is not provided with a filing allowance, an appropriate block member is provided with a bottom wall portion in the glass fitting groove (4 '). As an example, in this example, in the present example, the same member as the above-mentioned restriction block (7) is used as a block material (23) and similarly fastened to the glass movement restriction position with a screw and a nut, and a through hole ( A screw is screwed in from 16) and fixed so that it cannot rotate.
[0019]
The operation of the above example will be described below together with the glass fitting operation. As shown in FIG. 3, the restricting block (7) is temporarily held by tightening the screw (17) and the nut (18) and pressing the rotation stopper (9), and the indoor bead (12) has a fitting groove (12). The glass (5) is attached to the left and right vertical frames (3) and (3 ') by a flap operation while the outdoor bead (10) is not mounted, but the outdoor bead (10) is not mounted. , (4 ′), and adjust the right and left positions of the glass, and then insert a screwdriver or the like through the gap between the glass (5) and the outdoor bead fitting groove (8) to remove the regulating block (7). The glass is rotated to the glass movement restriction position in FIG. 2 against the temporary holding. By the rotation, the restricting portion (14) faces the side end surface of the glass (5) at a small interval, thereby taking a posture to prevent dangerous left and right movement of the glass (5), and at the same time, the restricting portion (14). ) Is separated from the pressure contact of the rotation stopper (9) with the stopper body (20), so that the stopper body (20) resiliently advances near the side end of the regulating portion (14), and thereby the regulating block (7). ) Automatically locks unrotatable.
[0020]
Next, a series of outdoor bead (10) is mounted in the groove (8 ') of the outdoor bead fitting groove (8), and at that time, the arm plate (21) of the rotary stopper (9), (21) and the filling piece (22) are pushed further inward by the depth of the fitting groove (8 '), whereby the stopper body (20) is brought into contact with the restricting portion (14) as shown in FIG. The bead (10) prevents the rotation stopper (9) from being locked to the locked position while the lock is strengthened by advancing far enough from the outer surface.
[0021]
If the control block (7) is not rotated to the glass movement control position in the installation of the outdoor bead (10), the stopper body (20) is moved from behind to the control section (14) of the control block. Since the bead (10) is pushed and floats, making it impossible to mount the bead (10) in the fitting groove (8 '), it is not necessary to forget to rotate the regulating block (7) to the glass movement regulating position.
[0022]
As another embodiment, the regulating block (7) is supported so as to be freely rotatable, and the regulating block (7) is temporarily held only by elastic pressing of the rotation stopper (9). Can be obtained in substantially the same manner as in FIGS. According to this example, as shown in FIG. 3, when the rotation stopper (9) that temporarily holds the restriction block (7) is lifted at the glass movement allowable position to release the press-contact, the restriction block (7) is under its own weight. It will rotate to the glass movement restriction position of FIG.
[0023]
【The invention's effect】
According to the invention of claim 1 of the present application, if the regulating block is temporarily held by the temporary holding means in advance at the allowable position of the surface material before the surface material fitting operation, the on-site work of the surface material fitting can be performed smoothly. In addition to the above, the restricting block, which has been rotated to the position for restricting the movement of the face material after the face material has been fitted, is locked non-rotatably by a rotation stopper, thereby preventing rotation of the control block due to vibration, impact, etc., and dangerous side movement of the face material. can be suppressed, the rotation stopper when mounting the bead to the outdoor Kanagawa bead fit groove when not move forward even pushed to the bead, know that restricting block is not rotated yet face plate movement restricting position Therefore, the rotation operation of the regulation block to the face material movement regulation position can be performed without forgetting.
[0024]
According to the second aspect of the present invention, in addition to the effect of the first aspect of the invention, the elasticity of the rotation stopper allows the restricting block to also serve as the temporary holding at the face material movement allowable position, and allows the restricting block to be used. When the stopper is rotated to the face material movement restricting position, the restricting block can be automatically locked in a non-rotatable manner by the elasticity of the stopper body.
