DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is excellent in weight balance characteristics at the time of reversing, enables smooth reversing operation of a shoji without requiring any force, and allows the degree of opening of the shoji to be wide over a wide angle range. The present invention relates to a reversing reversing window that can be arbitrarily adjusted and that can reliably close a shoji while ensuring airtightness.

[0002]

2. Description of the Related Art In recent years, several windows have been proposed in which a shoji can be turned over so that the outer surface of the window can be easily cleaned. However, most of this type of window is a side-sliding type reversing window, and a so-called overturning window, a sliding window, a protruding window, etc., which is opened and closed using the upper or lower end of the shoji as a rotation axis. There are few examples of reversing windows for smoke windows and ventilation windows. However, in the case of a sliding window or a protruding window, the shoji is opened to the outside and the glass is particularly dirty because it is exposed to the wind and rain. Is higher.

[0003]

However, in the case where the sliding door of the sliding window can be turned over, the sliding direction of the sliding door and the direction of gravity coincide with each other, so that the holding structure during the sliding operation poses a problem. Become. For example, when the shoji is particularly in a horizontal state during the reversing operation, a considerable rotational moment acts on the shoji, but if the operator is left with a force opposing this, the reversing operation itself becomes heavy labor. With
As soon as the operator accidentally releases his hand from the shoji, the shoji shimmers and rotates to cause breakage of the glass, which is extremely dangerous.

[0004] On the other hand, in the case of a conventional protruding window, there are many simple structures in which a protruding bar is simply connected to the lower end side of a shoji, and when the window is opened, this protruding bar is attached to a fastener of a frame portion. And hold the open state. In other words, it is a simple structure that can be adjusted in two stages of opening and closing, and there are few devices that can be held at an arbitrary inclination angle according to the occupant's preference.

[0005] Therefore, a main object of the present invention is to provide an excellent weight balance characteristic at the time of reversing, to enable smooth reversing operation of the shoji without requiring any force, and to make the shoji suddenly even if the hand is accidentally released. In addition to making it possible to adjust the degree of opening of the sliding door over a wide angle range, the sliding door can be securely closed while ensuring airtightness. It is to provide an inversion window.

A swing arm rotatably connected is provided, and the other ends of the first link and the second link are rotatably connected to the other end of the swing arm. is there. In this case,
It is desirable that the mounting position of the swing arm with respect to the shoji is within a range of ± 10% from the center point of the shoji vertical frame.

[0007] In addition, the structure for ensuring that the shoji can be closed while ensuring airtightness, the shoji has a protruding rod at the lower end side, and the protruding rod penetrates to the window frame side. The protruding rod has a rotating portion rotatable around the axis on the base side for attachment to the shoji, and is horizontally adjacent to the distal end side at least in the fenestration state. A bent portion around the axis is provided, and when the shoji is closed, the bent portion is protruded about the rotation center and the handle portion of the rod is bent upward to draw the shoji to the window frame surface and abut and hold the shoji. It is characterized in that it can be stored sideways along the lower frame of the shoji by turning it to the side.

In this case, in order to make it possible to arbitrarily adjust the degree of opening of the shoji over a wide angle range, the projecting rod is made freely extendable and engaging holes are formed at predetermined intervals along the longitudinal direction. The sliding door can be held at a predetermined opening / closing angle by engaging an opening adjustment pin member, which is formed on the opening / closing holding bracket and has a front end portion that can freely protrude and retract into the through hole.

More specifically, as shown in FIGS. 1 and 2, the window frame 2 comprises a wooden frame 2A on the indoor side and a metal frame 2B on the outdoor side, as shown in FIGS. The shoji 3 is accommodated in the metal frame 2B when the window is closed. On the indoor side surface of the wooden frame 2A, the projecting bar 4 is held at a predetermined projecting position at the lower end thereof, and is opened and closed as a contact fitting when the sliding bar 3 is locked by operating the projecting bar 4. A metal fitting 6 is provided, and a ventilating device 5 having an openable / closable ventilation door 5a is provided on the upper end side. For the window frame 2, as shown in FIG.
The screen door 9 can be provided on the indoor side of the opening.

As shown in FIG. 3, the supporting structure of the shoji 3 on the metal frame 2B is formed with two protruding lines 2a, 2a parallel to the inner side of the metal frame 2B near the indoor side. A slider 11 is provided that is movable along these ridges 2a, 2a, and the upper end side of the sash 3 is rotatably supported on a bracket piece 11a of the slider 11 with a support shaft 16. Further, a link fixing member 12 is fixed at an intermediate position on the inner side surface of the metal frame 2B by welding, bolts or the like. A swing arm 15 is provided in which the two links 14 are rotatably connected with support shafts 17 and 18 and one end of which is connected to the side of the shoji 3 by a support shaft 21. The other ends of the first link 13 and the second link 14 are rotatably connected to each other by support shafts 19 and 20. Note that these one set of sash support members 13, 14, and 15 are provided on both sides of the sash 3. The structural characteristics of the sliding door support structure will be described in detail in the section on the operation at the time of inversion, which will be described later, together with the operation.

On the other hand, as shown in FIG. 4, a projecting rod 4 attached to the lower end of the shoji 3 is installed so as to penetrate a wooden frame 2A and a through hole 6a formed in the opening / closing metal fitting 6, and The degree of opening of the sash 3 is adjusted for each predetermined angle by the amount of protrusion of the protrusion rod 4. As shown in detail in FIG. 5, the protruding rod 4 is attached to a lower frame 3B of the shoji 3 by a bolt or the like.
And a rotating head 4B, a joint shaft 4C having a substantially circular cross section, and handles 4D and 4E having a rectangular cross section.
And the handle portions 4D and 4E are
An insertion portion 4e extending from the end handle portion 4E is inserted into the one handle portion 4D, and can be extended just like a handle of a folding umbrella. The hole 4d is for engaging a biasing button formed on the insertion portion 4e when the handle portion 4E is expanded or contracted, and serves as an operation member for maintaining a state at the time of extension or releasing the extension. is there.

As shown in FIG. 7, the opening / closing holding bracket 6 has a through hole 6a through which the protruding rod 4 is penetrated, and when the protruding rod 4 is turned down to lock the sash 3 as shown in FIG. A receiving portion 6b having an L-shaped cross section for receiving and supporting the projecting rod 4 is formed, and the through hole 6a is formed in a side portion.
An opening adjustment pin member 6c having a tip protruding therein is provided. The opening degree adjusting pin member 6c is set in a resilient state by an internally provided urging means (not shown), or a tip end portion of the opening adjusting pin member 6c can be freely protruded and retracted into the through hole 6a by manual operation. , 4E formed in the side portions at predetermined intervals, thereby engaging the engagement holes 4c, 4c,... To maintain the protruding state and hold the shoji 3 at a predetermined open angle state.

The joint shaft 4 of the projecting rod 4
Both ends of C are connected to the rotary head 4B and the handle 4D with the shafts 4a and 4b, respectively, and are hinge portions H1 and H2 bent around the horizontal axis, and the rotary head 4B is attached to the mounting base side. Intervening joint shaft part 4
The handle portions 4D and 4E after C both rotate around the axis. This structure plays an important role in ensuring smoothness when opening / closing the shoji 3 and ensuring airtightness when the shoji 3 is closed. Specifically, FIG.
As shown in FIG. 7, the mounting and fixing portion 4A of the projecting bar 4 is shifted upward by the distance K as the sash 3 is opened, and the hinge structure easily absorbs the distance K corresponding to the shift. And the opening and closing operation of the shoji 3 can be performed smoothly.

In order to lock the shoji 3, as shown in FIG. 8, after closing the shoji 3, the handles 4 D and 4 E are bent upward about the hinge H 2 of the protruding rod 4 as the center of rotation. At this time, the door side of the shoji 3 is drawn toward the wooden frame 2A by the so-called leverage principle, and the indoor side surface of each shoji frame abuts against the sealing material 8 arranged and fixed on the back surface of the wooden frame 2A. Air-tightness is surely ensured. From this state, in order to store the protruding bar 4 in the lower frame portion, as shown in FIG. 9, the handle portions 4D and 4E are turned sideways and locked by the locking members 7 as indicated by wavy lines.

Incidentally, the shoji 3 is turned over for cleaning the glass when necessary. The supporting state at the time of the reversal of the shoji 3 is based on the operation stage diagrams shown in FIGS.
The operation will be described together with the operation of the first link 13 and the second link 14.

The reversing operation of the shoji 3 is performed by pulling out the protruding rod 4 from the through hole 6a of the opening / closing holding bracket 6 while the shoji 3 is being opened, and further lowering the rotating support at the upper end of the shoji 3 by the slider 11. You just need to do it. It is desirable to guide the slide-out while supporting the lower end of the shoji 3 with one hand while holding the protruding rod 4 until the middle of the reversal. The inversion operation can be easily performed.

The position of the support shaft 21 of the swing arm 15 is
It is preferable that the distance be within ± 10% from the center point of the vertical frame. Basically, by setting the center position, the right and left weight balance is balanced with respect to the support shaft 21 which also serves as a suspension point of the shoji.
Further, by supporting the shoji 3 with the two links 13 and 14, the swing arm 1
The fifth and second links 14 function as tension members in terms of stress, and the first link 13 functions as a compression member.
That is, during the reversing operation, the second link 14 functions as a tension support member that suppresses the rotation of the shoji 3 in the direction of gravity, and then the first link 13 supports the swing arm 15 in a direction to push up the swing arm 15. Since it functions as an arm member, the balance of force is structurally ensured, and the position of the swing arm 15 is uniquely determined by the two first links 13 and the second links 14 in each operation stage. Therefore, almost all of the weight of the shoji 3 is supported by these supporting members. Therefore, the supporting state of the shoji 3 is very stable.

In other words, even with the structure including the second link 14 and the swing arm 15, the reversing operation of the shoji 3 is possible, but in this case, it is necessary to support the weight of the shoji 3 by hand. Also, if you accidentally release your hand from the shoji 3 during operation, the shoji 3 suddenly slides out and is very dangerous,
Since the supporting structure of the shoji 3 is stable and the weight of the shoji 3 is supported, the reversing operation of the shoji 3 can be performed without requiring any force. Even if the hand is accidentally released, the shoji 3 does not start abruptly because the slider 11 moves upward relatively slowly and the shoji 3 closes.

By the way, it is desirable to provide a metal fitting for holding the inverted state of the shoji 3 for wiping the glass. In this example, as shown in FIG. 13, a hook member 22 is provided for the first link 13, and an inversion holding metal fitting 23 with which the hook member 22 is engaged is provided on the side of the metal frame 2 </ b> B. The holding metal fitting 23 at the time of reversing has a receiving engagement portion 23a with which the hook member 22 is engaged formed inside a plate material having a hat-shaped cross section, and a mounting bolt portion is formed as a vertically elongated hole so as to be vertically oriented. When the shoji 3 is completely turned over, it is slid up and down so that the receiving engagement portion 23a is engaged with the hook member 22 of the first link 13 and Hold the inverted state of.

[0023]

As described in detail above, according to the present invention, the shoji is supported by the two links and the swing arm, so that it has excellent weight balance characteristics at the time of reversing and smoothly without any force. Can be reversed. In addition, even if the hand is accidentally released from the shoji, the shoji does not suddenly slip down. Furthermore, while being able to adjust the opening degree of a shoji over a wide angle range,
At the time of locking, the shoji frame can be completely brought into close contact with the window frame surface by the effect of drawing the shoji by the bending of the protruding rod, so that the shoji can be reliably closed while ensuring airtightness.
