JP5760061B2 - A joinery consisting of an inner shoji and an outer shoji with a handle - Google Patents

Description

  More particularly, the present invention relates to a joinery in which a scissor is cut in a longitudinal hook so that a finger can be easily inserted into the pull of a handrail. .

Usually, a joinery composed of shojis has two or more shojis with inner and outer shojis, and at least one of them is moved left and right along the sill to be fully closed, half open, or fully open. Or
Normally, when opening the shoji, aside from the courtesy manners, move the inner shoji by placing your finger on the chisel or vertical rail of the inner shoji, or insert your finger into the pull handle provided on the chisel of the outer shoji. Or move the handicapped child by placing your fingers on the vertical fence or vertical rail of the handicapped child.

  However, when the shoji is fully opened, the inner shoji and the outer shoji are completely attracted, and the vertical chisel of the outer shoji and the chisel of the inner shoji overlap. At that time, it is easy to move the inner shoji because both the inner hoist and the vertical rail are on the near side. So difficult.

In other words, shoji paper is usually attached to the outside of the shoji, so if you turn your fingers to the outside of the shoji and try to put your fingers on the vertical fence or vertical rail of the shoji, the shoji paper will be in the way. I can't guess.
In addition, even if you try to apply your fingers to the pulling hand provided on the downside of the shoji, the shovel and the inside of the shoji are fully opened when they are fully open. Since it overlaps exactly with the shoji shochu, the shochu of the inner shoji on the front side gets in the way, and you cannot put your fingers into the hand of the shoji.

  Therefore, usually, insert the thumb or forefinger or middle finger into the gap between the medial fold and the medial fold, grab the medial fold, apply considerable force to the fingers, Will be moved. Or, care must be taken so that the shoji and the shoji are completely attracted so that the chisel of the shoji and the chisel of the shoji do not overlap, that is, do not fully open the shoji. Did not get.

In order to solve this problem, as shown in FIG. 7 , when the shoji is fully opened, a leftover (outward dimension) is provided between the shochu of the shoji and the shoji of the inner shoji. A method is known in which a finger is inserted into the hand of a handicapped child by using the left part (from the left part).
However, this method has a problem that the effective opening lateral dimension when fully opened is narrowed by the amount left behind.
In addition, when the shoji is fully opened, the leftover is obstructed, and the screen door, the sash such as an aluminum sash, the outer window frame itself such as a rain door, or the frame of the outer window is provided outside. In addition, it is difficult to put a finger on the key and the like, it is difficult to open the outer window frame, and it is difficult to open the key of the outer window.

In Cited Document 1, a rod-shaped member that is long enough to fit between two adjacent bars in a shoji is formed, and a groove that accommodates the tip of a human finger is formed on one side of the rod-shaped member. A shoji handle that has been made is disclosed.
However, the shoji handle composed of such rod-shaped members is troublesome to install on the shoji, and the installed beam is easily damaged, the appearance is unsightly, and it is necessary to bother to purchase it. It was.

In view of this, there has been a demand for a fitting that can easily and efficiently open and close the external shoji in a joinery that includes the inner shoji and the external shoji having a handle.
In particular, in recent years, there are many windows (including sweeping windows that can enter and exit) that are provided with outer window frames such as screen doors, aluminum sashes, and shutters on the outer side of the shoji screen. Since it is difficult to close the door, a fitting that can easily and efficiently open and close the shoji has been particularly desired.

JP 2007-077671

  The present invention has been made in view of the above-described background art, and its problem is to provide a joinery that can easily and efficiently open and close the shoji, particularly when the shoji is fully opened. In addition, an object of the present invention is to provide a “joint made up of inner and outer shojis” in which the first movement of the outer shojis is easy.

  As a result of intensive studies to solve the above-mentioned problems, the present inventor has found that when the shoji is fully opened, the longitudinal hand It has been found that the above-mentioned problems can be solved if a notch is provided in the heel portion, and the present invention has been completed.

  That is, the present invention is a joinery composed of a hand-operated child and a hand-operated child having a handle provided in a concave shape in a downarm, and when the door is fully opened, the hand-operated child and the hand-operated child are attracted to each other. The part of the inner heel of the inner tract located in the front part of the hand of the hand so that it is easy to insert a finger into the hand of the hand of the outer hand It is intended to provide a joinery characterized by being provided with a notch.

  According to the joinery of the present invention, in the joinery comprising the inner shoji and the outer shoji having a handle provided in a concave shape on the downside, the shoji is fully opened, Even when the shoji and the shoji are almost completely attracted and the chisel of the shoji and the shochu of the shoji overlap, it becomes easier to insert fingers into the hand of the shoji, It is possible to easily, efficiently and easily start the movement of the external shoji from the fully open state and easily close it.

In addition, since it is only necessary to make a cut in the part of the longitudinal spatula of the inner shingles located in the front part of the pulling hand provided in the vertical spatula of the external shoji, it is also possible to simply make a cut into the existing internal shingles later, It is not necessary to replace the entire inner shoji or “joint made up of inner and outer shoji”, and there is no need to install new parts, so it is possible to improve the joinery of the present invention at a very low cost. is there.
In addition, cuts are made in relatively strong vertical fences, and the mechanically weak vertical bars and horizontal bars are not touched, so there is no worry of damaging or breaking the shoji.

Even when the shoji is fully open, insert your thumb, forefinger, middle finger, etc. into the narrow gap between the chisel of the shoji and the shoji of the shoji, grab the chisel of the shoji, and put considerable force on the fingers Thus, it is not necessary to move the external shoji, and it is possible to start closing the shoji from the fully open state even by a person who does not hurt the finger and has weakness in the finger.
Further, according to the joinery of the present invention, since it is not necessary to put a finger into a narrow gap between the longitudinal spatula of the inner shoji and the shoji of the outer shoji, the shoji sill is placed so that the space between the inner shoji and the outer shoji is narrowed. Etc. (between grooves) can also be designed.
Also, care must be taken that the shoji and the shoji are completely attracted so that the chisel of the shoji and the shochu of the shoji do not overlap, that is, the shoji is not fully opened. There is no need.

As can be seen in the joinery as described above (as shown in FIG. 7 ), there is no problem that the lateral dimension of the effective opening when fully opened is narrowed by the amount left behind (extended dimension). When this is done, the remaining part will interfere with the operation of the outer `` sashes such as screen doors, aluminum sashes, outer window frames such as shutters, or keys provided on the frame of the outer window '', etc. There is no problem that it is difficult.

Furthermore, by providing the incision of the inner fold of the above-mentioned shoji from the side of the chisel to the back rather than the front of the chisel, it is difficult to see the notch from the front of the inner limb (from the inside of the shoji). The appearance as a joinery is not impaired.
In particular, since the original shape as a shoji has not changed much at least from the appearance, the traditional form of shoji can be protected.

  Further, as shown in FIG. 2 or FIG. 4, the incision of the longitudinal hook of the above-mentioned inner shrimp has a substantially elliptical spherical shape that spreads from the inside of the incision toward the outside from the side face to the back face. If it is provided, it becomes easier to insert fingers into the handle, and there is no problem aesthetically. In addition, since the volume of the cut portion can be reduced while maintaining the ease of inserting fingers, there is no problem that the longitudinal scissors of the inner pouch are inferior in strength due to the cut.

Furthermore, as shown in FIG. 6, if the pulling handle provided in the vertical manner is provided in the recessed portion of the entire pulling handle, when the fitting of the present invention is fully opened, Since a space is created in the vertical fold of the shoji screen, fingers are inserted into the space, and it is easier to insert fingers into the puller.
Also, if your fingers are inserted into the combined space of “the cut portion provided on the vertical hook of the inner shoji” and the above-mentioned “recess provided in front of the hand of the external shoji (the space in front of the hand)” Since it is good, the volume of the incision provided in the downspout of the inner pouch can be reduced, and the downpipe of the pouch does not deteriorate in strength.

In particular, the joinery of the present invention has a structure in which an outer window frame such as a screen door, an aluminum sash, or a shutter (including a sweeping window that can enter and exit) is provided (hereinafter referred to as “ When the shoji is fully opened, it is not only between the shoji and inner shoji but also between the shoji and the outer window frame. However, it is difficult to insert a finger, and in that case, it is extremely difficult to close the shoji (see FIG. 1B).
According to the present invention, even when there is the outer window frame, the above-described problems are solved, and there is no need to insert a finger into the gap simply, efficiently, and easily. It is possible to start closing the shoji from the fully open state without the need to put in.

It is a photograph which shows the external shoji and the inner shoji of the conventional joinery installed near the outside window frame. (A) It is not fully open, and shows a state where the inner and outer shojis are not completely brought together.

  Hereinafter, the present invention will be described, but the present invention is not limited to the following specific embodiments, and can be arbitrarily modified within the scope of the technical idea.

[Technical Field] The present invention relates to a joinery composed of an inner shoji and an outer shoji having a handle provided in a concave shape on a downside.
1 (a) and 1 (b) show an example of a conventional inner scissor 13, an outer shoji 12, a pulling handle 21, a vertical spat, etc. without a cut. FIG. 1 (a) shows a state in which the external shoji 12 is not completely attracted, and FIG. 1 (b) shows that the internal shoji 13 and the external shoji 12 are attracted, and the vertical spats overlap each other. Indicates the state.
Here, “inner shoji” refers to a shoji that is pulled to the room side or inside when the joinery 11 has at least two shoji, and when the shoji moves on the inside of the sill, A shoji that moves through the groove. “External shoji” means a shoji that is pulled to the corridor, garden, or outside when the joinery 11 has at least two shojis. When the shoji moves on the sill, A shoji that moves through the groove.

  The joinery of the present invention has at least two shojis, the inner shoji 13 and the outer shoji 12, but may have three or more shoji. In that case, if there is at least one shoji drawn to the room side or inside as viewed from the shoji, it is referred to as “foreign shoji”. In addition, when viewed from the shoji, if there is at least one shoji that is pulled to the corridor, the garden, or the outside, it is called “inner shoji”. Therefore, there may be a shoji that is both the external shoji 12 and the internal shoji 13.

In the external shoji 12, there is usually a concave handle 21 on the vertical shaft 14 of the external shoji. When opening and closing the shoji, usually the fingers are inserted into the “concave handle” of the shoji 12 and the shoji 12 is moved to the left and right.
At that time, for example, as shown in FIG. 1B, when the shoji 12 is fully opened and is completely brought into contact with the inner shoji 13, the shochu of the shoji is overlapped. It becomes impossible to insert a finger into the “concave handle” in FIG.

In such a case, the fitting of the present invention is provided with a notch 22 at least in the part of the longitudinal rod 15 of the inner limb located at the front portion of the handle 21 so that a finger can be easily inserted into the handle 21 of the outer cover 12 in such a case. It is provided.
FIG. 2 shows a joinery of the present invention, in which the outer shoji 12 is fully opened and the inner shoji 13 and the outer shoji 12 are attracted to each other and the vertical spats overlap each other.
When the scissors 22 are completely overlapped by providing the incisions 22 in the inner shoji 13, unlike the state shown in FIG. A finger can be inserted into the “concave puller”, and the external shoji 12 can be easily started to close.

  Since the joinery of the present invention is characterized by the inner shoji 13 in which the notch 22 is cut in the vertical shaft 15, the present invention refers to the “extrinsic child 12 having the inner arm 13 and the pulling handle 21 provided in a concave shape on the vertical shaft 14. In the joinery 11 constituted by the above, when the inner sward 13 and the outer sword 12 are attracted when fully opened, the vertical sword 14 of the outer sword and the vertical sword 15 of the inner limb overlap each other. The inner pouch is characterized in that a notch 22 is provided in a portion of the longitudinal hook 15 of the inner shuffler located in the front portion of the handle 21 so that fingers can be easily inserted into the handle 21 of the outer cover 12. But there is.

  The size of the notch 22 provided in the inner shoji 13 is such that a finger can be easily inserted into the handle 21 of the outer shoji 12, and at least the inner shroud located somewhere in front of the handle 21 of the outer shoji 12. The incision 22 of the inner limb 13 need not be in front of all the portions of the handle 21 of the outer limb 12. In other words, when the pulling handle 21 provided in a concave shape is vertically long, the notch 22 may be provided only in a part of the front portion of the pulling handle 21. Therefore, it may be a notch 22 having a vertical length such that only one or two fingers are inserted.

  Conversely, when the handle 21 is vertically short, the notch 22 may also be present in the front portion of the portion without the handle 21 including the front portion of the handle 21. The notch 22 may be continuous with the “notch 22 in the front portion of the puller 21”. Thus, for example, there may be an incision 22 over substantially the entire length of the scissor 15 of the inner limb.

For example, as shown in FIG. 2, the size of the notch 22 provided in the inner impingement 13 is slightly larger than the size of the handle 21 of the external obstacle 12, and is preferably large enough to see the entire handle 21. It is particularly preferable that the size is substantially the same.
It is preferable that the opening 25 in the inner surface of the vertical hook of the incision 15 of the inner shoji is substantially the same shape as the shape of the handle 21 of the outer shoji 12 or a shape larger than the shape of the handle 21.
The “back of the downspout” of the inner shoji 13 refers to the side facing the external shoji 12, and the handle 21 can be seen by the presence of the notch opening 25 in the back 16 of the downspout. You can put your fingers in

The specific size of the opening 25 at the depth of the downpipe of the notch 22 is not particularly limited, but the vertical direction is usually 14 mm or more and “the full length of the shoji downpipe”, preferably 17 mm to 100 mm. More preferably, it is 40 mm-80 mm, Most preferably, it is 50 mm-70 mm, More preferably, it is 55 mm-60 mm.
With the above length, there is no excess or deficiency with respect to 55 mm, which is the normal vertical length of the handle 21.

The lateral direction is usually 15 mm to “the full width of the shoji warp”, preferably 17 mm to 35 mm, and particularly preferably 20 mm to 30 mm.
If it is the said length, there will be no excess and deficiency with respect to 13 mm which is the normal horizontal length (width) of the handle 21 and the distance from the edge of a vertical hook.
In addition, the shape of the notch 22 that is long in the horizontal direction and penetrates the vertical saddle 15 of the inner shoji from left to right is not excluded, but because the shoji paper of the inner shoji 13 is not pasted on the penetrating portion, Since the shoji paper flutters at the part or wind enters from the part, it is preferable that the paper does not penetrate.

The size of the opening on the side surface 17 of the vertical gutter of the notch 22 is not particularly limited, but the vertical direction is preferably about the same as the size of the opening 25 on the back surface.
Although the size in the horizontal direction from the front to the back is not particularly limited, it is preferably 13 mm to 30 mm, and particularly preferably 15 mm to 20 mm. If it is too long, the appearance may be impaired, and the strength of the downpipe 15 may be weakened.

In the present invention, it is preferable that the notch 22 of the longitudinal hook 15 of the above-mentioned inner limb is provided from the side face 17 to the inner surface 16 of the longitudinal ridge so that it is difficult to see from the front side of the inner limb 13.
For example, in FIG. 2, the notch 22 is provided from the side face 17 to the back face 16 of the inner shovel of the shoji, and is not provided on the front face 18.

By making the cuts 22 in this way, when the shoji is viewed from the front (from the inside), that is, from the room side, the cuts 22 cannot be seen and the appearance is not impaired, and the shape of the traditional shoji is improved in appearance. Can keep.
In general, a person who is about to start closing the external shoji 12 from the fully open position stands at an opening location where the external shoji 12 will be closed, so that the hand 21 can be easily seen from the location through the notch 22. There is an effect that it is easy to insert.

  There is no particular problem with the shape of the notch provided in the longitudinal rod 15 of the inner shuffle as long as it is easy to insert a finger into the handle 21 of the outer shoji 12. Shape (an example is shown in FIG. 3), a shape (not shown) provided on a substantially prismatic side surface such as a substantially triangular prism, a substantially quadrangular prism, etc., uniformly in the vertical direction, from the inside to the outside of the cut. A shape provided in a substantially elliptical spherical shape that spreads out (an example is shown in FIGS. 2 and 4) and the like are preferable. The shape of the cut is not particularly limited, but is preferably long in order to easily insert a finger.

FIG. 3 shows an example of the cuts 23 that are provided in a substantially elliptical side surface uniformly in the vertical direction. FIG. 3 (a) is a perspective view of the cutout 23 provided in the longitudinal spatula 15 of the inner limb from the outer limb 12 side, that is, from the outside, in a state where the outer limb 12 is not present (a state where it does not overlap with the outer limb). FIG. 3B is a cross-sectional view taken along the line AA, in which the vertical scissors 15 are cut in substantially the middle of the cut 23.
If the cut is provided in the shape of a substantially elliptical column, when the finger is inserted into the cut 23, the finger naturally moves in the back direction along the side of the substantially elliptical column that is the wall of the cut 23 (disorder 12). It is easy to insert into the handle 21 of the external shoji 12. Moreover, it is preferable also in appearance.

FIG. 4 shows an example of the notch 24 provided with a substantially elliptical spherical shape in which the incision of the scissors 15 of the inner limb extends from the inside to the outside of the incision. FIG. 4A is a perspective view of the incision portion provided in the longitudinal spatula 15 of the inner shingles from the side of the outer shingles 12, that is, from the outer side in a state where the outer shingles 12 are not present (a state where they do not overlap with the outer hand children). FIG. 4B is a cross-sectional view taken along the line B-B in which the vertical rod 15 is cut at substantially the middle of the cut 24.
The shape of the cut 24 in this case is a shape that does not include the major axis or minor axis of an approximately elliptic sphere, and a shape that is cut parallel to the major axis is particularly preferable. When the shape does not include the major axis or minor axis of the substantially elliptical sphere, the shape extends from the inside of the cut 24 toward the outside, and the fingers can be easily inserted. The shape of the notch 24 is not particularly limited, but is preferably vertically long because it is easy to insert fingers.

  When the cut is provided in such a shape, when the finger is inserted into the cut 24, the finger naturally moves in the back direction along the side of the substantially elliptical spherical surface that is the wall of the cut 24 (on the side of the external obstacle 12). ) And is easily inserted into the handle 21 of the external shoji 12. Also, in the vertical direction, the finger naturally bends toward the middle of the handle 21 along the side of the substantially elliptical spherical surface that is the wall of the cut 24, and is easily inserted into the handle 21 of the external screen 12. In addition, it is particularly preferable in terms of appearance.

In the present invention, as shown in FIG. 5, the notch 22 of the scissors 15 of the shoji is provided so as to penetrate through the scissors 15 from the front surface 18 to the back surface 16 of the scissors 15. Is also preferable. FIG. 5A is a perspective view of the incision 22 provided in the longitudinal spatula 15 of the inner limb from the outer limb 12 side, that is, from the outside, in a state where the outer limb 12 is not present (a state where it does not overlap with the outer limb). FIG. 5 (b) is a cross-sectional view taken along the line CC of FIG.
Although FIG. 5 shows a case where a curved surface is penetrated, the surface may penetrate.
If it is penetrated, the appearance will be different from that of the normal shovel 15 of the shoji, but the fingers can be more easily inserted into the handle 21 of the shoji 12.

  In the present invention, as shown in FIG. 6, the handle 21 is provided as a whole on the depressed portion of the vertical saddle 14 of the external shoji, and when fully open, fingers are placed on the pull 21 of the external shroud 12. In order to facilitate the insertion, the joinery 11 in which the space 26 is provided in the portion of the vertical rod 14 of the outer shingles at the front portion of the handle 21 is further preferable.

If the pull handle 21 provided in a concave shape on the downpipe 14 is provided in a recessed portion as a whole pull handle, that is, if a space 26 is formed in the part of the vertical peg 14 of the outer screen of the front handle 21, Fingers are also inserted into the space 26, and it becomes easier to insert fingers into the puller 21.
In addition, since a finger can be inserted into the combined space of the “cut portion” of the inner shoji 13 and the space 26 of the outer shoji 12, the corresponding portion of the notch 22 provided on the longitudinal spatula 15 of the inner shoji. The volume can be reduced, and in particular, the depth can be reduced. Therefore, the longitudinal fistula 15 of the pouch is not inferior in strength by the notch 22.
That is, since the downspout 15 of the inner shoji and the downspout 14 of the external shoji can share the thinning of the downspout, the strength of the downspout does not deteriorate.

In recent years, a shoji sash has been installed inside a “outdoor window frame” such as a window having a structure in which an outer window frame 31 such as a screen door, an aluminum sash, or a shutter is provided. In many cases. In this case, the joinery 11 is installed close to the outer window frame 31.
The joinery of the present invention is preferable because the effect of the present invention described above is particularly effective when it is installed close to the outer window frame 31.

That is, as shown in FIG. 1B, when the outside window frame 31 is provided, when the shoji is fully opened, not only the outside shoji 12 and the inside shoji 13 but also the outside shoji 12 and the outside. It becomes difficult to insert a finger between the window frame 31, that is, it becomes difficult to pick up the vertical rod 14 of the external shoji with the finger, and the external shoji 12 is very difficult to close.
In the fitting of the present invention, even when the outer window frame 31 is provided, such a problem is solved, and there is no need to insert a finger into the gap simply, efficiently, and easily. It is not necessary to pick the heel 14 with fingers, and it is not necessary to apply force to the fingers, and it is possible to start closing the external shoji 12 from the fully open state.

  The fitting 11 according to the present invention is easy to open and close the external shoji 12, and it is easy to start closing the external shoji 12 from the fully open state. Therefore, the joinery 11 is widely used in any building or the like in which the shoji is used. It is also used to improve the existing inner shoji 13.
