JP 2003-90161 A

By the way, when the above-mentioned ledge structure is adopted, the ledge must be structured to be detachable from the ridge, and when attached to the ridge, it is not easily detached from the ridge and it is necessary to reliably support the glass. There is. For this reason, the finding dimension and the expected dimension of the heel increase, and the protruding width dimension from the window frame (protruding dimension in the prospective direction) also increases.
Therefore, the weight of the shoji increases, and since the pressing edge is necessary in addition to the heel, the number of members increases and the cost increases. In addition, since the size of the eyelid is increased, the area of the glass is reduced, and there is a disadvantage that the viewability, the daylighting property, and the designability of the window are deteriorated.
For this reason, there has been a demand for a joinery that can easily replace a face material such as glass in a state in which a shoji is suspended from the joinery frame without providing a ledge.

  An object of the present invention is to provide a joinery that can easily replace a face material without using a ledge and in a state where a shoji is suspended in a joinery frame.

The joinery of the present invention is a joinery comprising a joinery frame, a shoji that is rotatably attached to the joinery frame, and an arm that spans between the joinery frame and the shoji and regulates the opening angle of the shoji. The shoji is arranged in parallel to the rotation axis of the shoji, and when the shoji is opened, a door toe is formed between the joinery frame and a suspension provided in parallel to the door toe. A barb, two connecting rods disposed between ends of the door-end rod and the suspension rod, and two rod-connecting fittings for connecting the two connection rods and the door-end rod. The connecting bracket includes a connecting portion attached to the connecting rod and an attaching portion to which the door tip rod is attached, and the door tip rod is arranged in a longitudinal direction of the connecting rod with respect to the attaching portion of the rod connecting bracket. Attached to the saddle connecting bracket from the prospective side of the door toe By inserting the connector, the Tosakikamachi is connected to the connecting rail via the rail connecting fitting attachment portion of the stile connecting fitting, when the door head rail is mounted, the Tosakikamachi An exposed portion that is exposed to the prospective surface, and the arm includes a mounting bracket that is attached to the exposed portion of the flange coupling bracket, and an arm main body that is rotatably provided with respect to the mounting bracket. The attachment bracket is detachably provided along the longitudinal direction of the connection rod with respect to the flange connection bracket, and the attachment bracket is inserted into the exposed portion of the flange connection bracket from the attachment bracket, so that the attachment bracket is connected to the flange connection characterized Rukoto mounted on brackets.

The joinery of the present invention is a joinery in which the rotation axis of the shoji is horizontal, such as a protruding window, an inside fall window, and an outside fall window, and the rotation axis is provided at the end of the shoji (the suspension base side). Alternatively, it may be a joinery in which the rotation axis of the shoji is in the vertical direction, and the rotation axis is provided at the end of the shoji, such as an open window (single-opening, double-opening).
Further, the joinery of the present invention may be a joinery in which the rotation axis is not the end of the shoji, such as a horizontal axis rotation window or a vertical axis rotation window. In the case of the horizontal axis rotation window or the vertical axis rotation window, one of the two coffins parallel to the rotation axis may be a door-end coffin and the other is a hanging coffin. It is sufficient to use the side fence that facilitates the replacement of the face material such as the door toe. Furthermore, the joinery of the present invention may be a horizontal sliding window or a vertical sliding window.
Moreover, as a connection tool, a screw may be sufficient and a pin for connection may be sufficient.

According to the present invention, the door toe is attached to the connecting rod with a connecting tool such as a connecting screw. Since this connecting tool is inserted into the scissors connecting fitting from the prospective surface of the door-end scissors (screwed in the case of screws), the connecting tool is exposed when the shoji is opened. For example, in the case of an inward-facing window, the upper arm is a door toe, and when the shoji is opened, the prospective surface (upper surface) of the upper arm and the connecting tool are exposed to the operator who opened the window. Therefore, the operator can easily remove or insert the connector using a screwdriver or the like.
Moreover, since the door toe is provided so as to be detachable along the longitudinal direction of the connecting rod with respect to the rod connecting bracket (the direction in which the door toe is found), if the door is opened and the connecting tool is removed, The door toe can be easily attached and detached. Therefore, with the shoji attached to the joinery frame, a face material such as glass can be incorporated into the cage or the face material can be exchanged. Therefore, it is possible to easily replace the face material without using a ledge, and to improve the workability and maintainability of the face material.
In addition, since there is no need to use a ledge, compared to conventional shojis that use ledges, the size and expected dimensions of the heel can be reduced, and the width from the window frame can be reduced. The cost can be reduced. In addition, since the size of the eyelid can be reduced as compared with a conventional shoji using a ledge, the exposed area of the glass can be increased, and the viewability, lighting, and design of the window can be improved.
When using a connection screw as a connection tool, the connection rod and the suspension genre form a screw hole in the suspension genre and screw the connection screw from the connection rod to the screw hole of the suspension genre, as with a common shoji. However, it may be connected using a connecting bracket in the same manner as the door toe.

According to the present invention, since the mounting bracket of the arm is mounted on the exposed portion exposed to the prospective surface of the door-end rod in the rod-connecting bracket, the mounting bracket can be removed with the door-end rod attached.
If the mounting bracket is removed, the shoji can be opened greatly. For this reason, maintenance of parts, such as an airtight material, replacement work of the arm itself, etc. can be easily performed without disassembling the shoji. Further, the shoji can be detached from the window frame without disassembling, and the maintenance work of the shoji itself can be easily performed.

  Furthermore, a connecting hole into which the connecting tool for the door-toe fence is inserted and a connecting hole into which the connecting tool for the mounting bracket is inserted in the mounting portion of the saddle connecting bracket, along the expected direction of the shoji. It is preferable that the connecting hole of the connecting tool for the mounting bracket is provided on the side in which the shoji is opened compared to the connecting hole of the connecting tool for the door toe.

For this reason, when removing the connection tool for attachment brackets with a driver etc., compared with the case where the connection tool for door-end fences is removed, possibility that a joinery frame will interfere becomes low and can remove easily.
It is only necessary to remove the door-end fence only when the face material is installed or when it is replaced due to damage, and the frequency of removal is low. On the other hand, the arm mounting bracket needs to be removed during maintenance work of parts such as an airtight material, and the frequency is higher than the frequency of removing the door toe. Therefore, maintenance workability can be improved by configuring the fitting for the mounting bracket so that it can be easily attached and detached.

Further, the joinery of the present invention is a joinery comprising a joinery frame and a shoji that is rotatably attached to the joinery frame, and the shoji is arranged in parallel with the rotation axis of the shoji to When the door is opened, a door toe is formed with an opening between the door frame, a hanging heel provided in parallel with the door toe, and the door toe and the end of the hanging awn Two connecting rods and two hook connecting brackets for connecting the two connecting rods and the door toe hook, the hook connecting metal having a connecting hole into which a connecting tool for attaching the door toe rod is inserted.

According to the present invention, the door toe is attached to the connecting rod with a connecting tool such as a connecting screw. Since this connecting tool is inserted into the scissors connecting fitting from the prospective surface of the door-end scissors (screwed in the case of screws), the connecting tool is exposed when the shoji is opened. For example, in the case of an inward-facing window, the upper arm is a door toe, and when the shoji is opened, the prospective surface (upper surface) of the upper arm and the connecting tool are exposed to the operator who opened the window. Therefore, the operator can easily remove or insert the connector using a screwdriver or the like.
Moreover, since the door toe is provided so as to be detachable along the longitudinal direction of the connecting rod with respect to the rod connecting bracket (the direction in which the door toe is found), if the door is opened and the connecting tool is removed, The door toe can be easily attached and detached. Therefore, with the shoji attached to the joinery frame, a face material such as glass can be incorporated into the cage or the face material can be exchanged. Therefore, it is possible to easily replace the face material without using a ledge, and to improve the workability and maintainability of the face material.
In addition, since there is no need to use a ledge, compared to conventional shojis that use ledges, the size and expected dimensions of the heel can be reduced, and the width from the window frame can be reduced. The cost can be reduced. In addition, since the size of the eyelid can be reduced as compared with a conventional shoji using a ledge, the exposed area of the glass can be increased, and the viewability, lighting, and design of the window can be improved.

[Glass construction and maintenance procedures]
Next, a procedure for maintenance such as construction and replacement of the glass 26 in the small ventilation window (inside-down window) 6 will be described.
In the ventilation small window 6 of the present embodiment, as will be described below, the glass 26 can be installed and replaced in a state where the ventilation small window 6 is suspended (incorporated) in the inner shroud 4.
First, the shoji 20 is opened. Since the ventilation small window 6 is an inward-facing window, the upper ridge 21 side falls to the indoor side with the lower ridge 22 side as the rotation axis. Since the upper collar 21 is exposed indoors, the operator removes the connection screw 34 from the screw hole 251A of the collar connection fitting 25 using a screwdriver as shown in FIG.
Next, the upper rod 21 is pulled out obliquely upward, specifically, in a direction along the longitudinal direction of the vertical rods 23 and 24. At this time, a notch 213A is formed in the upper collar 21, and the notch 213A allows the upper collar 21 to move without interfering with the collar coupling metal 25. The upper collar 21 can be pulled out in the attached state.

  If the upper collar 21 is pulled out, the upper surface side of the shoji 20 is opened, so that the glass 26 can be installed between the vertical fences 23 and 24 or the glass 26 can be replaced. When the arrangement of the glass 26 is completed, the upper rod 21 may be disposed between the vertical rods 23 and 24 and attached using the connecting screw 34, contrary to the removal procedure.

[Parts and shoji maintenance procedures]
Next, maintenance procedures for parts such as the draining material 51, the airtight material 52, the screen door 60 described later, and the maintenance of the shoji 20 will be described.
Also in this case, the shoji 20 is first opened. Since the upper rod 21 is exposed indoors, the operator removes the connecting screw 35 from the screw hole 251B of the rod connecting bracket 25 using a screwdriver as shown in FIG. As a result, the mounting bracket 41 can be removed from the collar coupling bracket 25. That is, since the mounting bracket 41 is disposed in the exposed portion of the flange coupling bracket 25, that is, in the gap portion between the protruding piece 214 and the mounting piece 215 of the upper flange 21, it is obliquely upward, specifically, the vertical rods 23, 24. It can move without interfering with the upper collar 21 by pulling it out in the direction along the longitudinal direction. For this reason, the attachment bracket 41 can be removed in a state where the upper collar 21 is attached to the collar connection bracket 25.
If the mounting bracket 41 is removed from the shoji 20, the shoji 20 can be opened widely, and the screw of the stopper component 145 can be removed with a screwdriver or the like.
Next, the stopper part 145 is removed from the notches of the rails 131 and 141. Then, the slide member 43 of the inward-turning arm 40 is pulled out from the cutout portions of the rails 131 and 141 and removed. Thereby, the inward-turning arm 40 can be removed from the window frame 10 and the shoji 20.

Since the mounting bracket 41 can be removed from the shoji 20, the parts of the arm 40 such as the mounting bracket 41, the arm body 42, and the slide member 43 can be exchanged without disassembling the shoji 20.
Further, if the arm 40 is removed, the opening angle of the shoji 20 can be increased, so that the draining material 51, the airtight material 52, and the screen door 60 can be easily replaced and maintained without disassembling the shoji 20.
Furthermore, if the shoji 20 is rotated greatly, the arc-shaped recess 225 can be removed from the shoji mounting piece 121. Therefore, the shoji 20 can be removed from the window frame 10 without disassembling the shoji 20, and the maintenance work of the shoji 20 can also be performed.

In order to return the shoji 20 to the original state, a procedure reverse to the above procedure may be performed. That is, the slide member 43 of the inward-turning arm 40 is inserted into the notches of the rails 131 and 141 and guided to the rails 131 and 141, and the stopper part 145 is attached to the notches of the rails 131 and 141.
Further, the mounting bracket 41 of the inward-turning arm 40 is arranged while the groove 411 is inserted into the stepped screw 27. Then, the attachment bracket 41 may be attached to the flange connection bracket 25 using the connection screw 35.

[Installation procedure of screen door]
Next, a procedure for attaching the screen door 60 to the ventilation small window 6 will be described with reference to FIGS.
The screen door 60 includes a screen door 61 assembled in a square shape, and a screen 62 attached to the screen door 61. The screen door fence 61 includes a fin portion 611 protruding outward from the indoor side edge.
The fin portion 611 is in contact with the portion of the upper frame 11 and the vertical frames 13 and 14 to which the draining material 51 is attached from the indoor side, and is used as an allowance for the window frame 10. For this reason, the screen door 60 can be prevented from falling off to the outdoor side, and the screen door 60 can be attached and detached from the indoor side.

As shown in FIG. 7, such a screen door 60 removes the mounting bracket 41, opens the shoji 20 widely, and inserts it into the window frame 10 through the opening. At this time, a screen door stopper 65 is attached to the upper inner surfaces of the vertical frames 13 and 14 along the rails 131 and 141. A long hole is formed in the screen door stopper 65, and is attached to be slidable in the vertical direction by a screw 66 inserted through the long hole portion.
When the screen door 60 is attached, the screen door stopper 65 is moved upward.

Then, as shown in FIG. 8, the lower arm of the screen door rod 61 is engaged with the screen door guide rail 122 formed on the upper surface of the lower frame 12.
Further, as shown in FIG. 9, each fin portion 611 of the screen door 61 is brought into contact with the draining material 51 of the upper frame 11 and the vertical frames 13 and 14. Then, the screen door stopper 65 is slid downward and brought into contact with the indoor surface of the fin portion 611 of the screen door 61 to prevent the screen door 60 from falling down indoors.

Then, the mounting bracket 41 is attached to the shoji 20, and the shoji 20 is returned to the original state.
In addition, when removing the screen door 60, it can carry out in the reverse procedure of said attachment procedure.

According to this embodiment, the following effects can be obtained.
(1) The upper eaves 21 in the shoji 20 of the ventilation small window 6 are screwed from the upper surface (expected surface) of the upper eaves 21 to the eaves coupling fitting 25 attached to the inner surface upper ends of the vertical eaves 23 and 24. It is attached with a connecting screw 34. Furthermore, since the notch 213A is formed in the upper collar 21, there is no inconvenience that when the upper collar 21 is removed, the upper collar 21 is caught by the collar coupling metal 25 and cannot be removed.
For this reason, if the shoji 20 is opened, the operator can easily remove the connecting screw 34 and the upper collar 21. For this reason, the construction and replacement work of the glass 26 can be performed in a state where the shoji 20 is suspended from the window frame 10, and the workability and maintainability of the glass 26 can be improved.
Furthermore, since there is no need to use a ledge, it is possible to reduce the size and expected size of the heel and the width of the window frame compared to conventional shojis that use the ledge. The number of points can be reduced, and the cost can be reduced. Further, since the size of the eyelids can be reduced as compared with the conventional shoji screen using the ledge, the exposed area of the glass 26 can be increased, and the viewability, lighting, and design of the window can be improved.

(2) The mounting bracket 41 of the arm 40 is also attached to the flange coupling bracket 25 with a coupling screw 35 that is screwed from the upper surface (expected surface) of the upper collar 21. Therefore, if the shoji 20 is opened, the operator can easily remove the connecting screw 35 and the mounting bracket 41 (arm 40) from the shoji 20.
For example, when the mounting bracket 41 is screwed to the side surfaces (connection pieces 233, 243) of the vertical rods 23, 24, the summing rod 4C or the door-to-door rod 4D provided outside the vertical rods 23, 24 is used. If the expected dimension is large, the screw of the mounting bracket 41 may not be removed even if the shoji is opened. In addition, when the ventilation small window 6 is attached to the FIX window, there are cases where the casing is disposed outside the vertical rods 23 and 24 and the screw of the mounting bracket 41 cannot be removed even if the shoji is opened. In these cases, the arm 40 cannot be removed without disassembling the inner shroud 4 itself in which the ventilation window 6 is incorporated, and it becomes difficult to perform maintenance work on components such as the airtight member 52.
On the other hand, in this embodiment, the connecting screw 35 and the mounting bracket 41 can be removed from the upper surface side of the upper collar 21, and the arm 40 can be removed without being affected by the accommodation of the side faces of the vertical collars 23 and 24. Therefore, maintenance work for components such as the airtight member 52 and maintenance work for the shoji 20 can be easily performed. Moreover, the small window 6 for ventilation can be provided not only in a sliding window but in a FIX window.

(3) Furthermore, since the removal of the upper collar 21 and the removal of the arm 40 (mounting bracket 41) can be performed independently, the maintenance work of the glass 26 and the parts can be easily performed by removing the minimum parts. It can be carried out.

(4) Since the screen door 60 has the fin portion 611 of the screen door rod 61 in contact with the draining material 51 from the indoor side, it can be reliably prevented from dropping to the outside, and the screen door 60 can be easily detached from the indoor side. The maintenance work of the screen door 60 can be easily performed.
Furthermore, since the attachment hole of the screen door stopper 65 is a long hole and is arranged so as to be movable in the vertical direction along the rails 131 and 141, the screen door stopper 65 can be rotated indoors and outdoors. It can be surely prevented. For this reason, the fall of the screen door 60 to the indoor side can be reliably prevented.

(5) Since the connecting screw 35 of the mounting bracket 41 is disposed indoors from the connecting screw 34 of the upper collar 21, that is, on the side farther from the window frame 10 when the shoji 20 is opened, the connecting screw 35 is connected. It can be easily attached / detached compared to the screw 34. For this reason, parts maintenance work, such as the airtight material 52 having a higher maintenance frequency than the glass 26, can be performed more easily.

(6) Since the flange connecting bracket 25 is formed in a U-shaped cross section and the plate portion 253 is provided so as to be able to contact the notch 213A when the upper flange 21 is attached, the upper flange 21 is secured when the connecting screw 34 is screwed. It is possible to prevent the mouth from opening.

In addition, this invention is not limited to the said embodiment, Including other structures etc. which can achieve the objective of this invention, the deformation | transformation etc. which are shown below are also contained in this invention.
For example, as the heel coupling fitting 25, for example, a L-shaped fitting having a mounting portion 251 and a coupling portion 252 may be used.
Contrary to the above-described embodiment, the connecting screw 34 of the upper collar 21 may be arranged indoors with respect to the connecting screw 35 of the mounting bracket 41, that is, on the side farther from the window frame 10 when the shoji 20 is opened. Good.

It can be used for various swing-type fittings.
In addition, in the case of a horizontal axis rotation window or a vertical axis rotation window, it is only necessary to use one of the two parallel bars parallel to the rotation axis as a door head bar and the other as a hanging bar bar, and in particular, it is incorporated in a shoji bar. What is necessary is just to use the heel of the side where it is easy to exchange face materials, such as glass, as a door-end heel.
Moreover, the small window 6 for ventilation of this invention is not limited to the structure provided in the lower part of the inner impeller 4 of the sliding sash 1, and may be provided in the upper part of the inner impeller 4. As shown in FIG. In that case, the upper eaves 4A becomes the eaves facing the door-end eaves. Moreover, the small window 6 for ventilation of this invention may be provided in the external shoji 3 of the sliding sash 1, and may be provided in both the external shoji 3 and the internal shoji 4.
Furthermore, the small window 6 for ventilation of this invention is not restricted to what is provided in the sliding shoji of the sliding sash 1. FIG. For example, in a one-way window configured by incorporating a stationary screen and a sliding screen in a sash frame, the ventilation small window 6 may be mounted on either the upper side or the lower side of the stationary screen or the sliding screen. Further, in the FIX window configured by providing only the fixed shoji in the sash frame, the ventilation small window 6 may be incorporated in either the upper or lower portion of the fixed shoji.

  In addition, the present invention only needs to be configured so that at least the door toe can be removed from the coffin fitting.
