Thus, the deformation of the first projecting piece 32 can be prevented, the first projecting piece 32 of a window frame 2 need not be thickened, and the window frame 2 can be used in common with other sashes.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiver mounting structure for a sash locking device for pulling or locking a sliding door in a casement window or a sliding window, and a sash having the locking device.

[0002]

2. Description of the Related Art In a casement window or a sliding window, a sash locking device including a cam latch handle rotatably attached to a shoji and a receiving member attached to a window frame and engaged with the cam latch handle is used. Used. The receiving device of such a locking device is screwed to the window frame. However, when a positive pressure or a negative pressure is applied to the sash by wind, the load is concentrated on the receiving portion, so that the rigidity of the window frame is increased. It was attached to a high hollow portion (hollow portion) (see Japanese Utility Model Registration No. 2570477).

[0003]

By the way, in recent buildings, in order to form a comfortable living space and reduce energy used for cooling and heating to save energy, the heat insulation performance of outer walls and fittings is required. It is valued. For this reason, even as a sash window that constitutes the window of the building,
Insulation sashes having heat insulation performance are increasingly used.

[0004] At this time, the present applicant arranges a heat insulating cover on the inner peripheral surface exposed to the indoor side when the shoji is closed in the window frame in order to prevent dew condensation, so that the heat insulating performance and the dew preventing performance can be improved. We are developing a heat insulating sash with improved quality. Here, when a metal window frame made of aluminum or the like comes into contact with the heat-insulating cover, the heat insulating performance and the dew-proofing performance are reduced. Therefore, it is desired to reduce the contact area between the heat insulating cover and the metal window frame. I have. For this reason, we prototyped a window frame without the interior surface of the hollow part to which the receiver was attached.

However, in such a window frame, the receiving member is fixed to a mounting piece projecting from the inner peripheral surface of the window frame with a screw or the like. At this time, for example, in the case of a sliding window or the like in which a shoji opens to the outside of the window, when a positive pressure is applied to the shoji, the entire window frame passes through a sealing material (airtight material) that abuts over the entire length of the shoji. The force is not applied to the receiver because it receives the force, but if a negative pressure is applied, the force concentrates only on the receiver with the cam latch handle engaged, and the mounting piece with the receiver There was a risk of deformation.

In order to prevent such deformation, it is conceivable to improve the rigidity by increasing the thickness of the mounting piece.
In that case, there is a problem that a dedicated window frame to which the receiving device is attached must be manufactured. In particular, in the case of the side-slide windows, the receiver is usually attached to the lower frame.
Since this lower frame is also used for other casement windows such as a vertical sliding window, it is not necessary to make the lower frame mounting piece thicker for the horizontal sliding window. There is a problem that the manufacturing cost of the lower frame of the vertically sliding window also increases. On the other hand, if different lower frames are manufactured for the horizontal sliding window and the vertical sliding window, the types of lower frames increase,
There is a problem that the production efficiency is reduced and the production cost is increased.

An object of the present invention is to eliminate the need for thickening the mounting piece even when the receiving member is fixed to a mounting piece other than the hollow portion of the window frame, such as when the heat insulating cover is mounted. An object of the present invention is to provide a sash locking device receiving structure and a sash which can prevent deformation of the sash.

[0008]

SUMMARY OF THE INVENTION The present invention provides a handle rotatably mounted on a shoji which is openably and closably mounted on a window frame, and a receiver fixed to the window frame and engageable with the handle. The mounting structure for a receiving device in a sash locking device comprising a receiving device, wherein a receiving device mounting piece protrudes from an inner peripheral surface of a window frame, and either the indoor side or the outdoor side of the receiving device mounting portion is provided. And a reinforcing member is arranged on the side of the receiving member mounting piece and the receiving member in the direction of opening the sliding door.

In such a receiver mounting structure, the portion where the receiver is mounted is located on the side of the sliding door opening (for example,
Since the reinforcing member is placed on the outside of the window that opens to the outside (outside of the window), when the wind pressure is applied only to the receiver with which the handle engages (when a negative pressure is applied on the outside window), the load is applied to the reinforcing member. And the deformation of the receiving member mounting piece can be prevented. The load due to the wind pressure in the direction in which the shoji closes is supported and dispersed by the entire window frame when the shoji is pressed against the window frame via the airtight material, so that deformation occurs even in a portion where the reinforcing member is not provided. Nothing.

Since the load is supported by providing the reinforcing member, it is not necessary to increase the thickness of the receiving portion mounting piece of the window frame, and a sash (for example,
The vertical sliding window and the horizontal sliding window can be shared. For this reason, the number of types of window frames can be reduced and production efficiency can be improved,
Parts management becomes easy, manufacturing costs can be reduced, and assembly efficiency can be improved. Furthermore, since the reinforcing member is reinforced with a reinforcing member different from the receiving member, the receiving member itself does not need to have a special structure. For this reason, the receiving device can be shared with the sash receiving device having the hollow portion, and the manufacturing cost can be further reduced.

[0011] At this time, the reinforcing member has a reinforcing surface portion disposed on the side of the receiving member mounting piece and the receiving member in the direction of opening the sliding door.
The reinforcing member is formed in an L-shaped cross section with a locking surface portion orthogonally disposed from an end of the reinforcing surface portion, and an edge of the locking surface portion is locked by the window frame to open the sliding door of the reinforcing member. It is preferable that rotation to the side is prevented.

With this configuration, when wind pressure is applied only to the receiving member, the load can be transmitted to the window frame from the locking surface portion locked to the window frame and supported by the window frame. For this reason, it is not necessary to screw the reinforcing member to the window frame, and the assemblability is improved, and since there is no need to support the load only with the reinforcing member, the thickness of the reinforcing member can be relatively thin, and the like. Cost can also be reduced.

The sash of the present invention incorporates a window frame in which the upper frame, the lower frame, and the left and right vertical frames are framed four times, and the upper frame, the lower frame, and the left and right vertical frames are framed in a four-cycle frame, and the face material is incorporated. A sash comprising a shoji, wherein a handle rotatably attached to one of the frames of the shoji and a window frame corresponding to the frame to which the handle is attached. A receiving member mounting piece protruding from a peripheral surface, a receiving member fixed to one of the indoor side and the outdoor side of the receiving member mounting piece and capable of engaging with the handle, and a receiving member mounting piece; A reinforcing member disposed on the side of the receiver in the sliding door opening direction.

Even in such a sash, when wind pressure is applied only to the receiver engaged with the handle, the load can be supported by the reinforcing member, and the deformation of the receiver mounting piece can be prevented. Also, since the load is supported by the reinforcing member,
It is not necessary to increase the thickness of the mounting member of the window frame, and the window frame can be shared with other sashes or the like. For this reason, the number of types of window frames can be reduced, thereby improving production efficiency, facilitating parts management, reducing manufacturing costs, and improving assembly efficiency. Furthermore, since the reinforcing member is reinforced with a reinforcing member different from the receiving member, the receiving member itself does not need to have a special structure.
For this reason, the receiving device can be shared with the sash receiving device having the hollow portion, and the manufacturing cost can be further reduced.

At this time, the reinforcing member includes a receiving member mounting piece and a reinforcing surface portion disposed on the side of the receiving device in the direction of opening the shoji.
The reinforcing member is formed in an L-shaped cross section with a locking surface portion orthogonally disposed from an end of the reinforcing surface portion, and an edge of the locking surface portion is locked by the window frame to open the sliding door of the reinforcing member. It is preferable that rotation to the side is prevented.

With such a configuration, when wind pressure is applied only to the receiving member, the load can be transmitted to the window frame from the locking surface portion locked to the window frame and supported by the window frame. Eliminating the need to screw the reinforcing member to the window frame improves the assemblability and eliminates the need to support the load with only the reinforcing member, so the thickness of the reinforcing member can be made relatively thin, reducing costs. it can.

Further, the receiving member is provided with a receiving member main body and a fixing portion extending from the receiving member main body,
The exposed surface portion exposed to the indoor side when the shoji is closed in the window frame in which the receiving device is fixed is covered with a heat insulating cover,
It is preferable that the fixing portion of the receiving member is inserted into an opening formed in the heat-insulating cover and attached to the receiving member attaching piece.

If the exposed surface of the window frame is covered with a heat insulating cover, dew condensation on the window frame can be suppressed, and the heat insulating performance and the dew-proofing performance of the window frame can be further improved. In addition, by inserting the fixing part of the receiver from the opening of the heat insulating cover, only the receiving body is exposed on the surface of the heat insulating cover,
Since the fixing portion and the reinforcing member of the receiver can be hidden, the design can be improved. In addition, when wind pressure is applied to the receiver, the force is supported by the reinforcing member, so that even when the receiver is inserted with an opening formed in the heat insulating cover, a large stress is applied to the heat insulating cover. And the breakage of the heat insulating cover can be prevented.

Further, the window frame to which the receiving member is attached is composed of a non-ferrous metal indoor member and an outdoor member, and a heat insulating member connecting the indoor and outdoor members. Is preferably formed.

When such a window frame is used, since the heat insulating member is interposed between the indoor and outdoor members, heat transfer between the indoor and the outdoor can be reduced, and the heat insulating performance and the dew-proofing performance can be improved. Also,
Since the heat transfer from the outdoor side to the receiving member can be reduced, the occurrence of dew condensation at the receiving portion can also be suppressed.

Further, the receiving member mounting piece extends from the edge of the indoor member on the side of the heat insulating member toward the indoor side from a position away from the heat insulating member side edge, and extends from the rising portion to the heat insulating member side. It is preferable to be formed with an extension part and a mounting part extended from the extension part to the sash side.

As the heat insulating member disposed between the indoor and outdoor members, a heat insulating resin or the like is previously formed in a strip shape, and the strip-shaped heat insulating member is caulked and fixed by each of the indoor and outdoor members. There is a resin-injection-type heat-insulating member formed by injecting and solidifying a resin into a space (heat-insulating material injection pocket) between indoor and outdoor members. At this time, if the receiving piece is formed along the resin injection pocket, when the resin 100 is injected, the resin 100 rises along the receiving piece 101 as shown in FIG. As a result, the raised portion 102 must be cut and finished after the resin is solidified, and the production efficiency is reduced.

On the other hand, as in the present invention, if the receiving piece is bent in the shape of a crank and the rising portion is provided away from the resin injection pocket, no bulge is formed when the resin is injected. No finishing work is required later, and the production efficiency can be improved. Further, if the concave portion formed by the rising portion and the extending portion of the receiving member mounting piece is used as, for example, a locking portion of the heat insulating cover, the work of mounting the heat insulating cover can be facilitated.

Installed. In such a side sliding window 1, as shown in FIG. 2, a cam latch handle 7 rotatably attached to a shoji 3 is provided.
1 and the cam latch handle 71 fixed to the window frame 2.
Sash locking device 70 comprising
Is provided.

Specifically, the cam latch handle 71 includes a mounting base 71A mounted on the indoor side surface of the indoor member 52B of the lower frame 52, a rod-shaped lever 71B rotatably mounted on the mounting base 71A, This lever part 7
An engaging portion (cam latch) 71 </ b> C that protrudes from the end of 1 </ b> B and engages with the receiving member 72 is formed.

As shown in FIG.
A rectangular parallelepiped receiving body 72A to which the engaging portion 71C of the cam latch handle 71 is engaged, and a plate-shaped fixing portion 72B embedded in the receiving body 72A and extending downward from the receiving body 72A. It is comprised including. The fixing portion 72B is formed with two insertion holes 72D in which nuts 72C are fixed on the outdoor side. The fixing portion 72B of the receiving member 72 is provided with an opening 26 formed in the heat insulating cover 26.
E and is attached to the indoor side surface of the attachment portion 32C of the first projection 32 inside. That is, the first protruding piece 32 is protruded from the inner peripheral surface of the window frame 2, and serves as a receiving member mounting piece for mounting the receiving member 72.

On the outdoor surface of the mounting portion 32C to which the fixing portion 72B is mounted, a part of the covering portion 26A corresponding to this portion is cut out and is exposed to the outside. In the cutout portion of the covering portion 26A, in other words, in the portion where the first protruding piece 32 and the receiving member 72 are provided, the portion on the opening direction side (outside of the door) of the shoji 3 is
A reinforcing member 80 is provided.

The reinforcing member 80 is disposed on the side of the first protruding piece 32 and the receiving member 72 in the direction in which the shoji 3 opens (outside of the door), and is in contact with the outside surface of the mounting portion 32C.
1 and a locking surface portion 82 that is orthogonally disposed from an end (lower end) of the reinforcing surface portion 81 and extends toward the second projecting piece 33.
Are formed in an L-shaped cross section. Note that the thickness of the reinforcing surface portion 81 is substantially the same as the thickness of the covering portion 26A. Further, the edge of the locking surface portion 82 is inserted between the upper surface of the indoor main body 31 and the locking portion 33C when the reinforcing surface portion 81 is brought into contact with the mounting portion 32C. Locked. Thereby, rotation of the reinforcing member 80 in the opening direction of the shoji 3 is prevented. The reinforcing surface portion 81 and the mounting portion 32C of the reinforcing member 80 have the through holes 72D formed in the fixing portion 72B.
The insertion holes 81A and 32D are formed at positions corresponding to. Bolts 83 are inserted through the insertion holes 81A, 32D, and 72D from the reinforcing surface portion 81 side, and the bolts 83 are screwed into the nuts 72C.
The protruding piece 32 and the fixing portion 72B are connected to each other.

In such a side sliding window 1, when a negative wind pressure is applied to the shoji screen 3, the cam latch handle 71
The load concentrates on the receiver main body 72A with which is engaged. When the load is concentrated on the receiving body 72A, the fixing portion 72B and further the mounting portion 32C try to rotate and deform counterclockwise in FIG. Since they are connected by the nut 72C, the load can be supported by the reinforcing member 80. Also, the reinforcing member 80 does not rotate even if an excessive load is applied because the locking surface portion 82 is locked to the locking portion 33C.
B can be prevented from being deformed.

According to this embodiment, the following effects can be obtained. That is, since the reinforcing member 80 is arranged on the outdoor side of the attachment portion 32C to which the fixing portion 72B of the receiving member 72 is attached, even if the negative wind pressure is applied only to the receiving member 72 with which the cam latch handle 71 is engaged. Receiver 72
Can be supported by the reinforcing member 80, and the deformation of the first protruding piece 32 can be prevented.

Further, since the load of the receiving member 72 is supported by providing the reinforcing member 80, the first projecting piece 3 of the window frame 2 is supported.
The thickness of the window frame 2 does not need to be increased, and the window frame 2 can be shared with other sashes. For this reason, the number of types of the window frames 2 can be reduced, so that production efficiency can be improved, parts management can be facilitated, manufacturing costs can be reduced, and assembly efficiency can be improved. Further, the receiving member 72 is connected to a reinforcing member 8 different from the receiving member 72.
Since it is reinforced with zero, it is not necessary to make the receiving member 72 itself a special structure. For this reason, the receiving member 72 can also be shared with the sash receiving member having the hollow portion, and the manufacturing cost can be further reduced.

Further, the reinforcing member 80 is provided with a reinforcing surface portion 81 and a locking surface portion 82 and is formed in an L-shaped cross section, and the edge of the locking surface portion 82 is locked by the locking portion 33C to form the reinforcing member. Since the rotation of the shutter 80 in the direction of opening the sliding door is prevented, when a negative wind pressure is applied only to the receiving member 72, the load is transmitted to the indoor member 22 from the edge of the locking surface portion 82 to transmit the load to the indoor member 22. It can be supported by the member 22. For this reason, the reinforcing member 8
0 is not required to be screwed to the interior member 22 to improve the assemblability, and since it is not necessary to support the load only by the reinforcing member 80, the thickness and the like of the reinforcing member 80 can be made relatively thin. Can also be reduced.

The indoor member 2 to which the receiving member 72 is fixed is
2, the exposed surface portion exposed to the indoor side when the shoji 3 is closed is covered with the heat insulating cover 26, so that dew condensation on the window frame 2 can be suppressed, and the heat insulating performance and dew-proofing performance of the window frame 2 can be reduced. Can be more enhanced.

Further, the fixing portion 72B of the receiving member 72 is inserted into the opening 26E formed in the heat insulating cover 26, so that the first
Since it is attached to the protruding piece 32, only the receiver main body 72A is exposed on the surface of the heat insulating cover 26, and the fixing portion 72B of the receiver 72, the reinforcing member 80, and the like can be hidden.
The design can also be improved. In addition, when a negative wind pressure is applied to the receiving member 72, the force is supported by the reinforcing member 80, so that the opening 26 </ b> E is formed in the heat insulating cover 26 and the receiving member 7 is formed.
Even if 2 is inserted, a large stress is not applied to the heat-insulating cover 26, and the heat-insulating cover 26 can be prevented from being damaged.

Further, since the receiving member mounting piece for mounting the fixing portion 72B of the receiving member 72 is formed on the indoor member 22, since the heat insulating member 23 is interposed between the indoor and outdoor members 21, 22, the indoor and outdoor members are provided. Heat transfer can be reduced, and the heat insulation performance and dew-proof performance can be improved. In addition, since the heat transfer from the outside of the room to the receiving member 72 can be reduced, the occurrence of dew condensation at the receiving member 72 can be suppressed.

Further, since the first protruding piece 32 is bent in a crank shape and the rising portion 32A is provided away from the edge of the heat insulating member 23, the swelling occurs when the resin is injected when the heat insulating member 23 is formed. Since it is not formed, the finishing work is not required later, and the production efficiency can be improved. Further, since the locking portion 26D of the heat insulating cover 26 is locked by the concave portion formed by the rising portion 32A and the extending portion 32B of the first projecting portion 32, the heat insulating cover 2
6 can be easily installed.

Further, since a part of the covering portion 26A is cut out, when the reinforcing member 80 is disposed, the positions of the covering portion 26A and the reinforcing surface portion 81 can be aligned to form a flat surface. Thus, the design of the side window 1 can be improved.

The present invention is not limited to the above embodiment. For example, in the embodiment, the first protruding piece 32
Is bent in a crank shape to provide the rising portion 32A away from the edge of the heat insulating member 23. However, the present invention is not limited to this.
For example, the heat insulating member 23 may be linearly protruded from an edge or a position away from the edge. However, when the rising portion 32A is bent in a crank shape and provided away from the edge of the heat insulating member 23, no swelling is formed at the time of resin injection when the heat insulating member 23 is formed. This is preferable in that the finishing process is unnecessary and the production efficiency can be improved.

Further, in the above-described embodiment, the fixing portion 72B of the receiving member 72 is inserted into the opening 26E of the heat insulating cover 26. However, the present invention is not limited to this. For example, the mounting portion between the mounting portion 32C and the fixing portion 72B may be used. Only a part of the heat insulating cover 26 corresponding to the above may be cut out in advance, and after the mounting part 32C and the fixing part 72B are mounted, a heat insulating cover for closing this part may be mounted.

Further, the edge of the locking surface portion 82 is
3, but is not limited to this.
For example, the locking surface 82 may be fixed to the indoor main body 31 with a bolt or the like.

Further, the receiving member 72 is not limited to the one mounted on the indoor side of the first projecting piece 32, and may be mounted on the outdoor side, for example.

As the window frame, a general aluminum window frame may be used, or a non-ferrous metal outdoor member such as an aluminum resin composite window frame or an aluminum wood composite window frame may be used. Or you may use the window frame etc. comprised with the wooden indoor member. Furthermore, also as a shoji, a general window frame made of aluminum may be used, or a heat insulating shoji made of a non-ferrous metal outdoor member, an indoor member, and a heat insulating member connecting these members may be used. . Moreover, you may use the heat insulation sash which combined the frame member comprised by joining the non-ferrous metal outdoor member and the wooden indoor member. In addition, the heat insulating covers 11 and 26
Alternatively, as the synthetic resin forming the indoor members 51B and 52B, coloring may be performed by adding an appropriate pigment, or a synthetic resin mixed with wood flour and having a woody appearance may be used.
