Description

[Detailed description of the invention] [Purpose of the invention] "Industrial application field" The present invention relates to a window provided adjacent to an inside corner.

“Prior Art and Problems” When installing a shutter on a window with a wall next to the opening as described above, it is not possible to provide a door pocket on the inside corner with a normal sliding door type. It's impossible. Furthermore, shutters are usually made of multiple pieces, each of which is divided into sections. If a storm door is to be attached to such a window, it must be a folding shutter, but since the door is supported on a cantilever, it does not lock tightly when opened and may be unstable depending on the structure.

The invention disclosed in Japanese Patent Application Laid-Open No. 51-35536 constructs a bathtub shower by providing a door between the bathtub and its exterior, and by replacing the link of the fixed double slider mechanism with the door. I try to store it in. However, this conventional example requires as many door guide strips as there are doors, and has the disadvantage that the width of the guide strip increases when used for multiple shutters.

The present invention solves the problems with the above-mentioned window in which a wall surface is arranged as an inside corner next to the opening,
An object of the present invention is to provide a window with a shutter structure that can be stably supported.

[Structure of the invention]

``Means for Solving the Problems'' The present invention provides a window in which a wall surface is arranged with the outside side adjacent to an opening and an inside corner. established,
The guide strips are continuous at the corner of the entrance corner, and are rotatable around a vertical shaft fitted into each of the upper and lower guide strips, and guide means that is movable while being guided by the guide strips are guided through the opening. The upper and lower vertical axes of the guide means are arranged on the same center line on both sides of the upper and lower ends of the shutter to be opened and closed, and the shutter is composed of a plurality of sheets, and the upper and lower guide strips on the external side of the opening are one strip, This window is characterized by having the same number of guide strips on the top and bottom of the wall as the number of shutters.

"Operation" When the shutter on the entrance corner side is pushed outward, the guide means is guided by the upper and lower guide strips of the wall and the upper and lower guide strips of the opening, and the shutter rotates toward the interior corner wall. It continues to move forward and overlaps with the wall. The other shutters are first moved to the entrance corner along the guide strips above and below the opening, and then similarly moved to the wall side, but the shutters are moved one by one to the guide strips closer to the wall using multiple guide strips above and below the wall. It can be paid. Closing the shutters is the opposite of the above.

"Example" Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is a plan view, Fig. 2 is a front view from the outside of Fig. 1, Fig. 3 is a sectional view taken along line GG in Fig. 2, and Fig. 4 is a view of the upper side corresponding to Fig. 1 from below. This is a plan view.

A wall 20 is arranged on the outside side adjacent to one side of the opening 3 to form an inside corner, and on the other side, a wall 24 is arranged at right angles so as to form a crank shape together with the opening 3 and the wall 20. The upper and lower parts of the opening 3 are the upper frame 1 of the opening frame 9.
1. Horizontal guide grooves 13 and 14 are provided along the outer side of the lower frame 12 as guide lines for the upper frame 11 and the lower frame 12, respectively.
and are provided by integral or separate members. A plurality of horizontal guide grooves 15, 15', 16, 1 are provided on the upper and lower sides of the wall 20 as guide lines along the wall 20.
Rails 22, 23 provided with 6' are fixed.
The upper guide groove 13 and guide grooves 15, 15' as well as the lower guide groove 14 and guide grooves 16, 16' are bent at the inside corner and are continuous.

Two shutters 17, 17' are provided in the opening 3,
It is supported by upper and lower guide grooves 13 and 14. That is, the number of shutters 17, 17' and the guide grooves 15, 15' or 16 provided above and below the wall 20,
The number of threads 16' is the same.

Vertical shafts 18, 18' are fixed on the same center line at positions directly above the end surfaces of the vertical frames on both sides of the upper ends of the shutters 17, 17', that is, near the four corners of the shutters 17, 17'. Rollers 19, 19' are rotatably engaged with the vertical shafts 18, 18'.
Swivel wheels 21, 21' are attached to both sides of the lower end of the shutter 17 so as to be rotatable about the center line vertically below the shutter 18'. These own stocks 21, 21' are vertical axes and have no caster angle, and when a wheel with a small scrub radius and a wheel tread near the vertical axis passes through the corner of the guide grooves 14, 16 or 14, 16'. This is suitable because there is little misalignment between the center and the rollers 19, 19'.

The width of the guide grooves 16 and 16' is the same as that of the guide groove 14, respectively.
The guide grooves 15 and 15' each have the same width as the guide groove 13.

As shown in the figure, at least circular portions are formed at the intersections of the guide grooves 14 and the guide grooves 16, 16', respectively, so that the movable wheels 21, 21' can rotate about vertical axes.

The shoji for opening and closing the opening 3 is made up of four shojis: outer shojis 7, 7' and inner shojis 8, 8', but this portion can also be an inward-opening shoji.

The operation of opening the shutters 17, 17' from the closed position of the shutters 17, 17' in FIG. 1 will be described. When the inner shoji 8 is opened and the shutter 17 on the right side is moved to the right, it shifts slightly and then stops. In that position roller 19
are located at the corners where the guide grooves 13 and 15 meet, and the movable wheel 21 is also located at the position where the guide grooves 14 and 16 meet, so that the shutter 17 cannot be moved to the right in the facing direction. Next, when the shutter 17 is pushed outward,
The roller 19 enters the guide groove 15 as it is, and the swivel wheel 21 rotates 90 degrees about its own vertical axis, changes direction, and enters the guide groove 16. When the shutter 17 is pushed, the roller 19 and the swivel wheel 21 move into the guide grooves 15 and 1.
The roller 19' and the free wheel 21' roll in the guide grooves 13 and 14, respectively, and take the position shown by the two-dot chain line in FIG.
If you move the left end of 7 to the right, the shutter 17 will be attached to the wall 20.
The roller 19' is at the matching corner of the guide grooves 13 and 15, and the swivel wheel 2
1' are located at the matching corners of the guide grooves 14 and 16.
In this state, the shutter 17 is completely opened.
The length of the guide grooves 15 and 16 is such that the shutter 17 can fit therein, and the edge of one end of the shutter 17 is located at the dead end of the guide grooves 13 and 14.

Next, to open the shutter 17' on the left side of FIG. 1, open the outer shoji 7' and move it to the right.
The shutter 1 moves by rolling the shutters 3 and 14.
The end of the shutter 7' hits the edge of the shutter 17 that was opened earlier and stops. In this position, the roller 19 of the left shutter is in a position where the guide grooves 13 and 15' meet, and the swivel wheel 21 is also in the same position as the guide grooves 14 and 16'.
This is the position where the two are compatible. Here, shutter 1 on the left side
7' outward, the roller 19 remains in the guide groove 15', and the swivel wheel 21' rotates 90 degrees around its own vertical axis to change direction and move into the guide groove 16'.
to go into. When the shutter 17' is pushed, the roller 19 and the swivel wheel 21 roll in the guide grooves 15' and 16', respectively.
The roller 19' and the free wheel 21' are connected to the guide grooves 13 and 14.
When the left end of the shutter 17' is moved to the right, the shutter 17' is in a position parallel to the wall 20. , the roller 19' has the guide groove 13,1
5', and the swivel wheel 21' comes to the matching corners of the guide grooves 14 and 16'. In this state, the shutter 17' is completely opened. If you push the shutter 17', which was closed later, slightly outward in the direction of view, it will not close by force. That is, the length of the guide grooves 15' and 16' is preferably greater than the width of the shutter 17 so that the shutter 17' on the left side in FIG. 1 can be accommodated sufficiently.

To close the shutter, first move the shutter 17' that was closed slightly inward and move the vertical stile portion on the indoor side to the left, so that it can be closed in the opposite way to when it was opened. The shutter 17 that was previously closed can be closed by moving the vertical stile portion on the indoor side to the left in the opposite direction to when it was opened.

In the embodiment, there are two shutters, but there is no problem with two or more shutters, and the number of shutters and the guide grooves provided on the rails 22 and 23 are made equal.
