[Detailed Description of the Invention] The present invention relates to a sash frame attachment device used for attaching a sash frame to an opening in a wall or roof of a building.

Conventionally, when attaching a sash frame to an opening in the wall or roof of a building, it is common to screw the sash frame to the member that forms the opening, such as a steel frame or a wooden frame. It was hot. However, since the entire circumference of the sash frame must be screwed, it is very troublesome to install on site, especially when working outdoors in winter or in places with poor working conditions. The problem was that it was inconvenient and often took too much time.

The present invention was developed in view of the above problems, and is a sash that can be installed simply by fitting the sash frame to the peripheral frame attached to the opening in the wall or roof of a building. It is an object of the present invention to provide a frame mounting device.

Specifically, a locking protrusion is formed on the inner periphery of a peripheral frame that is framed in a rectangular shape and is attached to an opening in a wall, roof, etc., facing toward the opening, and a locking protrusion is formed on the peripheral frame. A rotating locking piece is attached to the outer periphery of the sash frame to be fitted, which is biased toward the locking protrusion of the peripheral frame by a spring body and engages with the locking protrusion when the sash frame is fitted; It is an object of the present invention to provide a mounting device for a sash frame in which the rotational locking piece can be released from engagement with the locking protrusion by operating it through an opening for removal operation formed in the sash frame.

Hereinafter, embodiments of the present invention will be described based on the drawings. Fig. 1 is a front view showing an embodiment of the present invention in use, Fig. 2 is an enlarged sectional view taken along the arrow-line in Fig. 1, and Fig. 3 is the main part in Fig. 2. FIG. 4 is a partially cutaway side view viewed from the direction of the arrow in FIG. 3.

In the figure, reference numeral 1 denotes a peripheral frame, which is attached to a panel member 3 that forms an opening 2 by assembling frame members into a rectangular shape. The inner frame body 5 is bent to leave a substantially rectangular gap between the inner frame body 5 and the inner frame body 5. Outer frame body 4
A mounting piece 6 that can be inserted into the panel member 3 is formed on the panel member 3, and the inner frame body 5 is fixed to the outer frame body 4 at two places. A locking protrusion 7 having a triangular cross section is provided on the vertical frame 5a of the inner frame 5 forming the inner periphery of the peripheral frame 1 so as to protrude along the longitudinal direction so as to face the opening 2 side. There is.

In the figure, reference numeral 8 denotes a sash frame, which has a substantially inverted L-shape in cross section, and extends around the outer periphery of the left and right vertical frames 8a facing the vertical frame 5a of the inner frame 5 constituting the peripheral frame 1. Three movable locking pieces 9 are attached at each location. This rotation locking piece 9 has a contact portion 9 having an I-shaped cross section.

A rectangular mounting hole 11 is provided in the central mounting portion 9c, and a shaft 12 with a rectangular cross section is provided in this mounting hole 11.
is inserted. One shaft 12 passes through three rotation locking pieces 9, and the mounting portion 9c of the rotation locking piece 9 is attached to a shaft support member 13 bolted to the sash frame 8 and having an inverted U-shaped cross section. It is supported by a shaft. Further, a spring body 14 is loosely inserted into the mounting portion 9c of the rotation locking piece 9, one end is in contact with the abutment portion 9a, the other end is fixed in contact with the shaft support member 13, and the rotation locking piece 9 The entire body is urged to rotate toward the locking protrusion 7 of the peripheral frame 1.

A holding part 15 is provided on the outer frame 8b of the sash frame 8 in a protruding manner at a position corresponding to the locking protrusion 7 when the sash frame 8 is attached to the peripheral frame 1. This clamping part 1
5 is a cushion member 15b (for example, made of soft synthetic resin) fitted into the groove 15a, which cooperates with the abutting portion 9a of the rotary locking piece 9 to sandwich the locking protrusion 7;
This allows the rotational locking piece 9 to exert its engagement force. Further, an opening 16 is provided in the vertical frame 8a of the sash frame 8 at a position corresponding to a recess 10 provided in the operating portion 9b of the rotation locking piece 9, and a lid 17 is placed over the opening 16. This opening 15 is used to rotate the rotation locking piece 9 against the biasing force of the spring body 14 by inserting the tip 18 of a screwdriver from here and pressing it against the recess 10. It is.

In the figure, reference numeral 19 denotes an interior member, which is in contact with a part of the sash frame 8. In the figure, 20 is an opening/closing body such as a window.

Further, in the illustrated example, the inner frame body 5 of the peripheral frame body 1 is partially provided corresponding to the installation position of the rotation locking piece 9, but it may be a so-called one-piece frame member. Of course. The number of rotation locking pieces 9 to be installed is also not limited to the illustrated example.

The frame members of the peripheral frame 1 and the sash frame 8 are mainly formed of extruded materials such as aluminum.

Next, a case will be described in which the sash frame 8 is attached to and removed from the peripheral frame 1 in the illustrated embodiment.

First, the installation of the sash frame 8 will be explained. In this case, the sash frame 8 is placed in a position where it can fit into the inner circumference of the peripheral frame 1, and the sash frame 8 is placed in a position where it can fit into the inner periphery of the peripheral frame 1, and the sash frame 8 is moved from the outside of the opening 2 toward the inside [in the direction of arrow X in the figure]. , the sash frame 8 is pushed in while pressing the abutting portion 9a of the rotary locking piece 9 against the locking protrusion 7. Then, the contact portion 9 rotates by the tip of the locking protrusion 7 against the biasing force of the spring body 14, and overcomes the locking protrusion 7.

The abutting portion 9a that has overcome the locking protrusion 7 is the spring body 1
4, the locking protrusion 7 is rotated back toward the root side, and comes into contact with the vertical frame 5a of the inner frame body 5 and stops. At this time, the cushion member 15b of the clamping portion 15 provided on the outer frame 8b of the sash frame 8 comes into contact with the inner frame body 5, and works together with the rotation locking piece 9 to exert a clamping force. Further, a part of the sash frame 8 comes into contact with the interior member 19. That is, the sash frame 8 is supported and fixed simply by fitting into the peripheral frame 1. Then, the opening/closing body 20 such as a window may be attached in this state.

Next, the case where the sash frame 8 attached as described above is removed from the peripheral frame 1 will be explained. In this case, the lid 1 of the opening 16 provided in the vertical frame 8a of the sash frame 8
7 is removed, and the tip 18 of a screwdriver is inserted through the opening 16 and pushed in while applying it to the recess 10 of the rotation locking piece 9. Then, the rotational locking piece 9 rotates against the biasing force of the spring body 14, as shown by the two-dot chain line in the figure, and is released from the engagement state with the locking protrusion 7.

This operation may be performed at one location on each of the left and right sides of the sash frame 8. One shaft 12 is inserted into the mounting hole 11 of the rotation locking pieces 9, which are provided three on each side of the left and right sides, and since this shaft 12 has a rectangular shape, one rotation lock When the stopper piece 9 rotates, the other rotational locking pieces 9 also rotate in conjunction. That is, this interlocking arrangement allows the sash frame 8 to be easily removed.

Then, as described above, the rotation locking piece 9 is attached to the locking protrusion 7.
When the sash frame 8 is pulled outward from the opening 2 (in the direction opposite to the direction indicated by the arrow X in the figure) while keeping it separated from the sash frame 8, the sash frame 8 easily separates from the peripheral frame 1.

As explained above, the sash frame mounting device according to the present invention forms a locking protrusion on the inner periphery of the peripheral frame attached to an opening in a wall, roof, etc., and also forms a locking protrusion on the outer periphery of the sash frame. Since the rotating locking piece is attached which is biased by a spring body and engages with the locking protrusion of the peripheral frame, the attachment of the sash frame to the peripheral frame is simply a matter of attaching the sash frame to the peripheral frame. This can be done very simply and easily just by fitting them together. Furthermore, in on-site construction, especially in outdoor construction in the winter or in locations with poor working environments, it can be expected to greatly reduce the burden on workers, and at the same time, it has the great effect of reducing the economy.

Furthermore, since the rotation locking piece can be operated from the opening formed in the sash frame, there is an effect that the locking piece can be easily removed by releasing the engagement state with the locking protrusion by an operation from the outside.
