Description

[Detailed Description of the Invention] The present invention relates to a window shutter that has a handrail provided inside the shutter curtain and can project outward in conjunction with the raising and lowering of the handrail.

Utility Model Publication No. 48-19464 as a technology to project outside together with the guide rail when the shutter is down. Jitsukō 49
-2938th Jitsuko Sho 49-3946 bells are known.

1 Utility Model Publication No. 48-19464 has a U-shaped support rod attached to the window frame so that it can rise and fall freely, and both ends of the support rod are slidably engaged with the guide grooves of the guide rail, and the upper part of the guide rail is It is cut at the lintel, connected at the hinge, and pivoted so that it can swing freely in the front and rear directions.

Since the U-shaped support rod was installed on the drainage board across the window sash, there was a drawback in that the window sash side became a collection of dust that could not be cleaned out.

The guide rail is cut at the top and hinged for swinging.

Because the guide rail was thin and narrow, small hinges had to be used, which caused problems in terms of strength.

2 Utility Model Publication No. 49-29380, which was filed by the applicant of the present invention, connects the lower end of the guide rail with a blocking plate that prevents the shutter curtain from falling to provide strength, and the protruding pieces are foldable. It is.

However, the extruded piece protruding from the guide rail was weak against crosswinds and could not provide sufficient strength.

3 Utility Model Publication No. 49-39462 is a system in which a disk-shaped support plate is fixed to the winding shaft, and the top of the guide rail is fixed to this with bolts, and the entire shutter rotates together with the rail using the bearing 4 as the pivot point. The protrusion angle is determined by a suitable support rod.

The present invention aims to improve the above-mentioned protruding window shutter and provide a protruding window shutter that is superior in various aspects such as sunshading effect, ventilation effect, safety, and design.Please refer to the attached drawings below. Examples will now be described.

A shutter case 1 is attached to the upper part of the window frame, and a known winding device 2 is housed inside.

3 is a shutter curtain, which is guided by a protruding guide rail 4 to be opened and closed.

The protruding guide rail 4 is located inside the vertical frame 5, and its upper end is hinged with a hinge fitting 6 so as to be rotatable back and forth, and its lower end is fixed to the lower frame 7.

8 is fixed to the building with a drainage board.

9 is a handrail.

The handrail 9 consists of a Kasagi 9a, a handrail 9b1 and a handrail seat 9c.
Rollers 10 are attached to both ends of the cap 9a, and the rollers 10 roll within roller guides 11 provided on the protruding guide rail 4.

A hinge fitting 12 is attached to the main sliding seat 9c,
The hinge fitting 12 is fixed to the lower edge of the window.

The handrail can be swung by pushing or pulling the Kasagi indoors or outdoors.

Reference numeral 13 denotes a lock built into the handrail 9b, which can be locked and unlocked by lifting and dropping the opening provided in the lower frame 7.

Details of the lock 13 are shown in FIGS. 4 and 5.

14 is a wide handrail for attaching a lock attached to the center of the cap 9a.

The handrail 14 is formed wide as shown in FIG. 5, and has a lock mounting groove 15 on the indoor side.

Reference numeral 16 denotes a support body for the lock 13, which is appropriately fixed in the lock mounting groove 15.

An opening is provided in the lower frame 7 corresponding to the position of the lock 13.

If the upper part of the lock 13 is raised and lowered, it can be inserted into and removed from the opening in the lower frame, and locking and unlocking can be easily performed.

Referring to Figure 6, the end of the Kasagi on the handrail (Figure 1
The details of the section (as viewed from the arrow) are shown.

11 is a bearing hole 17 of the shaft 10a of the roller 10 made of synthetic resin.
The bearing block is made of synthetic resin and has a Kasagi edge closure 17b integrally molded on the side thereof.

The bearing block 17 is shaped like a ring that fits exactly into the hollow part 18 of the Kasagi-9a.

19 is a handrail mounting groove provided on the lower surface of the cap 9a.

Referring to FIG. 7, details of the projecting guide rail 4 according to the present invention are shown.

A shutter guide 20 of a window shutter and a roller guide 11 are arranged side by side on the protruding guide rail 4, and these are integrally formed of aluminum or the like.

21 is a mounting groove for a sound-deadening resin or the like.

22 is a hollow portion provided at the rear of the roller guide 11.

A protruding guide rail is pivotally supported at the upper end of this hollow portion via a back plate so as to be protrusive.

The roller 10, which is supported by a bearing block 17 fitted into the cap 9a, rolls within the roller guide 11 and can project the window shutter.

FIG. 8 is an exploded detailed view of the upper support structure of the protruding guide rail 4 mentioned above.

The hinge fitting 6 is composed of a bracket mounting portion 6a and a guide rail pivot portion 6b.

Reference numeral 25 denotes a bracket mounting block, and the notches 26 and 27 of the bracket 24 are hooked onto the hook.

28 is a mounting hole. The guide rail pivot portion 6b is integrally provided at the lower end of the bracket attachment portion 6a, protrudes in an inverted shape, and has a pin hole 29 provided at the lower end.

On the other hand, in the protruding guide rail 4, the roller guide 11 and the shutter guide 20 of the window shutter are integrally molded. After aligning it with the pin hole 29, a pin 33 is inserted and it is rotatably attached.

With the above configuration, in order to project the shutter in the state shown by the solid line in FIG. 3, first, (1) lift the lock 13 to release the lock.

(2) Hold the handrail cap 9a and move it forward (outward, third
When the handrail 9 protrudes in the direction (imaginary line in the figure), the handrail 9 rotates around the hinge fittings 12 on both sides of the handrail seat 9c, and the rollers 10 on both sides of the Kasagi roll within the roller guides 11.

Accordingly, the protruding guide rail 4 is protruded forward and opened as shown by the imaginary line in FIG.

With the above configuration, the shutter guide and roller guide are arranged side by side and integrally molded, making it easy to manufacture, and the protrusion of the protruding guide rail can be operated in conjunction with the protrusion of the handrail at the same time, making the operation extremely smooth. It will be done.

The protruding guide rail is supported by a hinge at the top and only rotates at this point, so there are no steps on the guide rail, and the window shutter opens and closes smoothly, with very little noise.

The upper part of the protruding guide rail is pivoted, and when it is protruded, the kasagi at the top of the handrail touches the bottom frame, and the handrail seat at the lower end of the handrail is hinged to the lower edge of the window, so the handrail itself is reinforced. It plays the role of preventing shaking.

Therefore, even if the shutter is down when it protrudes, it can withstand crosswinds and drafts from below.

When the shutter of this application is protruded, there is no step in the guide rail and the upper guide part holds the shutter appropriately, so it is easy to change the opening degree of the shutter in this state, and it also maintains the set position. is also possible.

Therefore, it has excellent operability and ventilation, and generates little noise.

Since the protruding guide rails are connected by the lower frame, the inner diameter is kept constant and strong.

When the handrail is not protruding, it is used as a normal handrail, and when it is protruding, the handrail is fully extended and closes the opening at the bottom of the shutter, making it safe for children to fall.

If the shutter is fully opened and the guide rail is used to protrude, the handrail will fall down almost horizontally and close the opening below the shutter, so it can also be used to dry futons and laundry.
