DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window frame having a decorative frame on an outdoor side.

[0002]

2. Description of the Related Art Window frames can be classified into the following two types based on the difference in the connection structure between upper and lower frames and left and right vertical frames. That is, in the first type, both ends of the upper and lower frames and the left and right vertical frames are cut at right angles in the longitudinal direction, and in many cases, both ends of the upper and lower frames abut on opposing surfaces of the left and right vertical frames. Then, a screw is penetrated from the outside of the vertical frame into the vertical frame, and is further screwed into a screw hole provided in the upper and lower frames to be connected. The second type cuts both ends of the upper and lower frames and the left and right vertical frames at 45 degrees with respect to the longitudinal direction, cuts the upper frame, the upper surface of the vertical frame, and the lower frame. The surface and the cut surface at the lower end of the vertical frame are respectively abutted, and a screw is usually penetrated from the outside of the vertical frame into the vertical frame, and further screwed into screw holes provided in the upper and lower frames for connection.

In the first type of connection structure, the connection strength between the upper and lower frames and the vertical frame is large, and watertightness is secured at the contact surface between the cut surface of the upper and lower frames and the opposite side surface of the vertical frame. Although it has the advantage of being easy to maintain, the vertical line that appears on the contact surface between the cut surface of the upper and lower frames and the vertical frame has a weak point that it is inferior in design, especially when the window is viewed from the outdoor side. is there. In the second type of connection structure, the abutting surface is inclined at 45 degrees and extends along a line extending radially outward from the center of the window.
Better than kind. However, since the connection strength of each frame is relatively weak, when an external force is applied, a V-shaped minute gap is apt to be generated on the abutting surface, and the rainwater falls down on the window frame due to the capillary action generated in the minute gap. There is a risk of infiltration into the body.

In view of the above, in the first type of window frame having high connection strength and high water tightness, a frame material having both ends cut at 45 degrees on the outdoor side portion of the window frame is joined by abutting the cut surfaces. In some cases, it is desired to provide a decorative frame having high designability (hereinafter simply referred to as a frame). Conventionally, in order to attach a picture frame to a window frame, as shown in FIGS. 7 and 8, a structure in which a picture frame (OF) is added to an outdoor end of a window frame WF has been adopted. FIG. 7 shows a case in which a window frame WF1 is used in which the outdoor side end extends to the vicinity of the outdoor side surface of the exterior material E of the outer wall W, and a sealing material S is packed between the exterior material E and the window frame WF1.
The frame material constituting the frame is screwed to the outdoor end of F1. FIG. 8 is a view in which a frame OF is connected to the outdoor end of the window frame WF2, and a sealing material S is filled between the frame OF and the exterior material E.

[0005]

In the case of FIG. 7, it is necessary to increase the wall thickness of the outer wall W of the building, and the frame OF protrudes more outward than the outer wall W. As in the case of the window frame, there is a problem in connection strength, and a minute gap that impairs the appearance is often generated at the abutting portion of the 45-degree cut surface. Further, since the sealing material S does not seal a gap between the frame OF and the outdoor end face of the window frame WF1, it is impossible to prevent rainwater from entering through the gap.

[0008] In the case of FIG. 8, the amount of projection of the frame OF from the outer wall W is reduced, but a small gap is formed between the frame OF and the window frame WF 2. There is a problem that is impaired. Further, the problem that a minute gap is generated in the cut surface at 45 degrees due to insufficient connection strength of the frame and the appearance is impaired is the same as the case of (a).

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to attach a picture frame to an outdoor portion of a window frame without easily increasing the wall thickness. It is an object of the present invention to provide a window frame with a frame, which can ensure the watertightness and the strength, and maintain the aesthetic appearance of the frame.

[0008]

In order to solve the above-mentioned problems, a window frame with a frame according to the present invention has a simple design for both the window frame and the frame. That is, the window frame extends in the longitudinal direction of each frame along a common vertical plane parallel to the window opening surface at the outdoor end of the upper frame, the lower frame, and the left and right vertical frames constituting the window frame. A bottom wall is formed, and a protruding edge protruding outward from a portion of each bottom wall opposite to the center of the window frame and extending in a longitudinal direction of each frame is formed, and the window frame is assembled. In this state, a fitting recess is formed in which the bottom wall and the protruding edge of the entire frame can be fitted into the frame continuously in a rectangular shape. In addition, the frame is formed by connecting four frame members of upper, lower, left and right, each of which is cut at 45 degrees in the longitudinal direction, at the cut surface, and is connected to the fitting recess of the window frame. It is characterized by being fixed. With the above configuration, the window frame is formed with a fitting recess whose outer periphery is continuous in a rectangular shape at the outdoor end. The frames are connected by abutting the 45-degree cut surfaces at both ends of the four frame materials. Therefore, the frame has a good appearance. Further, when mounted on the window frame, the periphery thereof is surrounded by the protruding edge and the bottom wall constituting the fitting recess, so that the weak point of insufficient strength in the case of the butt connection of the 45-degree cut surface is overcome. I have. Therefore, generation of a minute gap on the butted surface is prevented, and watertightness between the frame and the window frame is also ensured.

The picture frame has an inner wall continuous in a rectangular shape along a vertical plane common to the indoor side end, and an outer wall extending from the outer peripheral end of the inner wall in the outdoor direction and continuous in a rectangular shape. However, it is desirable that the fixing member be fixed in a state in which it is in close contact with the bottom wall and the protruding edge of the fitting concave portion of the window frame. Thus, the picture frame formed by abutting and connecting the 45-degree cut surfaces is firmly fixed to the fitting recess of the window frame, and is significantly reinforced. Window frames are also reinforced by frames.

[0010] The projecting edge of each frame of the window frame projects outward from a mounting edge for fixing the frame to the outer wall, and the projecting edge receives a sealing material packed between the window frame and the exterior material. It is desirable to double as a receiving member. Thereby, the sealing operation can be easily and quickly performed, and the watertightness is improved.

More specifically, the upper frame 1 has a bottom wall 11 extending in the longitudinal direction of the upper frame along a vertical plane at an outdoor end of a main wall 13 for holding the window closing member CM at the center of the window. In the case of the upper frame 1, a protruding edge 12 extending horizontally in the outdoor direction from the upper end of the bottom wall 11 is formed. Have been. Since the outer mounting edge 14 for fixing the upper frame 1 to the building outer wall W extends further upward from the upper end of the bottom wall 11, the projecting edge 12 is attached to the mounting edge 14.
It is projected to the outdoor side more. In the illustrated example, the bottom wall 11 and the protruding edge 12 are continuous in an inverted L-shaped cross section. At the indoor side end of the main wall 13 of the upper frame 1, an inner mounting edge 15 for fixing the upper frame 1 to a wooden frame 7 described later is formed.

In the lower frame 2, a bottom wall 21 extending in the longitudinal direction of the lower frame 2 along a vertical plane is formed at an outdoor end of a main wall 23 for holding the window closing member CM at the center of the window. And the end of the bottom wall 21 opposite to the center of the window frame, that is,
In the case of the lower frame 2, a protruding edge 22 extending horizontally from the lower end of the bottom wall 21 in the outdoor direction is formed. Since the outer mounting edge 24 for fixing the lower frame 2 to the building outer wall W extends further downward from the lower end of the bottom wall 21, the protruding edge 22 protrudes more outward than the mounting edge 24. Will be.
The bottom wall 21 and the protruding edge 22 are continuous in an L-shaped cross section. The main wall 23 of the lower frame 2 has a required strength,
As in the related art, one square tube is formed together with the bottom wall 21, the lower wall 26, and the inner wall 27. At the indoor side end of the main wall 23, an inner mounting edge 25 for fixing the lower frame 2 to a wooden frame 7 described later is formed.

The left and right vertical frames 3 and 4 are provided at the outdoor end of the main wall 33 for holding the window closing member CM at the center of the window with respect to the left vertical frame 3 of FIG. A bottom wall 31 extending in the longitudinal direction of the vertical frame is formed along a vertical plane parallel to the window opening surface. In addition, in the case of the vertical frame 3, A protruding edge 32 extending horizontally in the outdoor direction from the outer wall end of the bottom wall 31 is formed. Since the outer mounting edge 34 for fixing the vertical frame 3 to the building outer wall W extends further from the end of the bottom wall 31 toward the outer wall, the protruding edge 32 projects more outward than the mounting edge 34. It will be. And the bottom wall 31 and the protruding edge 3

In the illustrated example, the bottom wall 3 is used to secure the required strength.
It is preferable that one square tube is formed together with the outer wall 36 and the inner wall 37. However, when the window closing member CM is lightweight or does not open and close, the main walls 33 and 43 of the vertical frames 3 and 4 may not constitute a part of the cylindrical body. At the indoor side end of the main wall 33, an inner mounting edge 35 for fixing the lower frame 2 to a wooden frame 7 described later is formed.

When the upper and lower frames and the left and right vertical frames are assembled into a rectangular frame as usual, the bottom wall 1 of each frame is
1, 21, 31, 41 are continuous in a rectangular shape along a common vertical plane parallel to the window opening surface, and the protruding edges 12, 22,.
32, 42 are continuously formed in a rectangular shape along four surfaces perpendicular to the window opening surface, and the bottom wall and the protruding edge form a fitting concave portion H that is open in the outdoor direction.

On the other hand, in FIGS. 2 and 3, OF is a picture frame. The frame OF is formed by connecting four frame members (51 to 54) made of the same metal shape as the window frame WF in a rectangular shape. As in the conventional case, each frame material is formed in a hollow shape and has the same cross-sectional shape.
The frame is cut at five degrees, the cut surfaces are abutted, and each end of an L-shaped corner block (not shown) is pressed into one of the frame materials to form a rectangular frame. . In the present invention, each frame material extends along the common vertical plane at the indoor side end.

Since 2, 22, 32, and 42 also serve as the receiving member of the sealing material, the sealing material is firmly received, and the sealing operation can be performed easily and quickly. Also, the protruding edges 12, 22, 3
Since 2, 42 are provided outside the outer mounting edges 14, 24, 34, 44, rainwater is prevented from penetrating to the nailing portion of the mounting edge, and the window frame mounting stability is maintained for a long time. Will be retained. Also, even if the sealing material S deteriorates,
There is no danger of rainwater seeping through between the window frame and the picture frame.

Since the main part of the present invention is in the frame mounting structure as described above, the type of the window closing member CM and the holding structure thereof are arbitrary. The illustrated first embodiment of FIG.
A panel, for example, a glass plate is used as the window closing member, and is fitted and killed. For this reason, the holding structure of the window closing member is a pair of inner and outer locking edges 1 provided on the main walls 13 and 23 of the upper and lower frames.
6, 17, 28, 29, and locking edges 38, 48 and pressing edges 39, 49 provided on the main walls 33, 43 of each vertical frame. 5 and 6 show an example in which a panel with a frame, for example, a glass sash is held openably and closably as the window closing member CM. The illustrated example has a holding structure for holding the glass sliding door in the form of a hinged door. That is, one end of a pair of upper and lower horizontal V-shaped links 9 is pivotally connected to the upper and lower sides of the hinged door 10, and the other end is hinged to the upper frame 1 and the lower frame 2, near the center of the free end of the hinged door. The door is unlocked and locked or the hinged door is opened and closed via a handle 100 attached to the door. The glass shoji can also be held in a single sliding door or sliding door format.

According to the above embodiment, the lower frame 2, the vertical frames 3, 4
Since the bottom walls 21, 31, and 41 are formed by a part of the hollow portion, the strength of the window frame itself is very large, and the strength of holding the frame of the fitting recess H of the window frame is also large. Is suppressed to the utmost, and the window frame is prevented from giving a distortion force to the frame. Therefore, even if the frame has a structure in which the 45-degree cut surfaces at both ends of each frame material are abutted and joined, no wedge-shaped minute gap is generated on the abutted surface, so that the design of the frame is improved. Damage is prevented. Also, the protruding edges 12, 22 provided on each frame of the window frame,
32, 42 are projected more outwardly than the outer mounting edges 14, 24, 34, 44, and the sealing material S is packed between the exterior material 105 of the building outer wall W and the projecting edge, so that the sealing operation is simple and quick. Can be. Further, since the protruding edge also serves as a sealing material receiving member, watertightness is ensured even if the expected width of the main wall of the window frame is reduced, so that it is not necessary to increase the wall thickness of the building outer wall. That is, it is possible to mount the window frame with a frame while minimizing the amount of protrusion from the outer wall of the building, using the existing outer wall of the building as it is. Further, since the sealing material is packed between the protruding edge and the exterior material, a decrease in window frame mounting stability due to infiltration of rainwater into the fixing portion of the mounting edge is prevented.

[0022]

As described above, according to the present invention, each of the upper frame, the lower frame, and the left and right vertical frames constituting the window frame has an outdoor side end along a common plane parallel to the opening surface. With a bottom wall extending in the longitudinal direction of the frame, and a projecting edge protruding in the outdoor direction from a portion of the bottom wall opposite to the center of the window frame, and a protruding edge extending in the longitudinal direction of each frame, the frame is continuously formed in a rectangular shape. A fitting recess that can be fitted is formed, and the picture frames are connected by abutting 45-degree cut surfaces at both ends in the longitudinal direction, and are fitted and fixed in the fitting recesses of the window frame. When installing the picture frame on the outdoor part of the frame, the picture frame can be easily installed without increasing the wall thickness, that is, without increasing the wall thickness, watertightness is ensured, and strength is ensured. Thus, the beauty of the picture frame is maintained.

According to the second aspect of the present invention, the inner wall and the outer wall of the frame are fixed in a state in which they are in close contact with the bottom wall and the protruding edge of the fitting recess of the window frame, so that the frame and the window frame are mutually reinforced. In addition, the design of the frame is maintained, and the watertightness is improved. Claim 3
