Description

Door and window frames

The present invention relates to a door and window frame arranged around a door or other door and window body.

In the past, in this invention, for example, as described in Patent Document 1, there is a door and window frame, which comprises: a vertical frame body having an opening portion at the upper end connected to the internal space; a horizontal frame connected to the upper end side of the vertical frame body and extending horizontally; a connecting piece welded to the end side of the vertical frame body; and screws for assembling the horizontal frame to the vertical frame body and the connecting piece.

When this type of door and window frame is installed on the inner edge of the opening of the main body of a building, etc., a portion that protrudes slightly from the main body wall to the front side is ensured on the vertical frame main body and the horizontal frame. The protruding size of this portion is sometimes called the protrusion or protrusion size.

Therefore, when the door and window frame is installed on the inner edge of the opening of the main body wall, in order to ensure the size of the protrusion, a part of the opening at the upper end of the vertical frame body is sometimes exposed to the outside of the main body wall. In addition, in such cases, there is a risk that impurities or pests may invade the exposed opening or that operators may come into contact with the opening.

Therefore, in the door and window frame of Patent Document 1, a separate rectangular frame-shaped cover member is fitted into the opening at the upper end of the vertical frame body and fixed by welding or the like.

<Specific implementation form>

Next, the specific implementation form with the above characteristics is described in detail according to the diagram.

In the following description, "width direction" refers to the horizontal width direction of the door and window frame (left and right direction according to Figure 1). In addition, "depth direction" refers to the thickness direction of the door and window frame that is roughly orthogonal to the "width direction".

Also, "frame inner side" refers to the inner side of the door and window frame, and "frame outer side" refers to the outer side of the door and window frame.

FIG1 shows an example of a door and window equipped with the door and window frame of the present invention.

The door and window 1 has a door and window main body A capable of opening and closing, and a door and window frame B surrounding the door and window main body A in a rectangular frame shape, and the door and window frame B is embedded in the inner edge of the opening of the wall in the main body of a building, etc.

According to the example in the figure, the door and window body A is a roughly rectangular plate-shaped door. In the door and window body A, one end side of the door width direction is rotatably supported by a hinge a1 on a vertical frame member 10 of the door and window frame B. In the figure, symbol a2 is a knob used for opening and closing operations, etc.

The door and window frame B has a vertical frame member 10 extending in the vertical direction, an upper frame member 20 connected to the upper end of the vertical frame member 10 at a substantially right angle and extending in the width direction, and a lower frame member 30 connected to the lower end of the vertical frame member 10 at a substantially right angle and extending in the width direction.

Two vertical frame members 10 are arranged at intervals in the horizontal width direction.

Each vertical frame member 10 is extended in the vertical direction with a substantially C-shaped cross-section, and has an upward opening portion 10a at its upper end that communicates with the space inside the vertical frame member 10. The opening portion 10a is closed by a closing portion 23a of the upper frame member 20 described later.

To explain in detail, each vertical frame member 10 has a frame inner side plate portion 11 that is continuous in the vertical direction to form a surface on the inner side of the frame, wide plate portions 12, 12 that extend from one end side and the other end side of the frame inner side plate portion 11 in the depth direction toward the outer side of the frame in the width direction, and inward plates 13, 13 that protrude inwardly in a mutually opposing manner from the end portion of the wide plate portion 12 on the outer side of the frame on one end side and the end portion of the wide plate portion 12 on the outer side of the frame on the other end side (see Figures 3 and 4).

The frame inner plate portion 11 has a convex portion 11a protruding toward the inner side of the frame at the center in the depth direction. The convex portion 11a makes the convex cross-sectional shape continuous in the vertical direction.

When the door and window body A in the open state is fully closed, the protrusion 11a acts as a door stopper to receive the surface of the door and window body A in the closing direction.

In addition, a fitting portion 14a is provided on the upper end side of the inner side plate portion 11 of the frame so as to fit in a manner that the fitting portion 20a of the upper frame member 20 does not move in the width direction and the depth direction.

The fitting part 14a is formed by providing a cutout part 14 which is open at the top and recessed downward at the center of the depth direction of the upper end side of the frame inner side plate part 11 of the vertical frame member 10. That is, the edge parts on both sides of the cutout part 14 function as the fitting part 14a. Each fitting part 14a is formed in the shape of a flat plate protrusion that intersects the upper frame member 20 at approximately right angles.

In addition, a small cutout portion 14b is provided on the lower edge of the cutout portion 14, where the cutout portion 14 is cut at the center of the edge in the depth direction.

To explain in detail, the small cutout 14b cuts the lower edge of the cutout 14 into a concave shape at a position corresponding to the convex portion 11a, and the upper end of the convex portion 11a is also cut open.

Furthermore, the cutout portion 14, the fitting portion 14a and the small cutout portion 14b of the above structure are provided on the lower end side of the inner side plate portion 11 of the frame in a vertically symmetrical manner.

The wide plate portions 12, 12 on both sides are respectively formed into flat plates roughly orthogonal to the inner side plate portion 11 of the frame, and are continuous over the entire length of the vertical frame member 10.

In addition, the inward plates 13, 13 on both sides are formed into flat plate protrusions that are spaced apart and face each other in the depth direction. A plurality of positioning pieces 15 are fixed at appropriate intervals in the vertical direction between the inward plates 13, 13 (see FIG. 3). The positioning pieces 15 are positioned on the unillustrated fixing member (anchor, etc.) on the side of the main body opening.

The vertical frame member 10 constructed as described above is formed by bending a flat metal plate, and before the bending, the cutout portion 14 is formed by pressing or the like.

In addition, the upper frame member 20 integrally comprises: a frame inner side plate portion 21, which is continuous in the width direction so as to form a downward surface of the frame inner side; upward plates 22, 22, which respectively face upward from one end side and the other end side in the depth direction of the frame inner side plate portion 21; and inner plates 23, 23, which protrude inwardly so that the upper end side of the upward plate portion 22 from one end side and the upper end side of the upward plate portion 22 from the other end side face each other (see Figures 2, 3 and 5).

The inner side plate portion 21 of the frame has a convex portion 21a protruding downwardly from the inner side of the frame at the center in the depth direction. The convex portion 21a makes the convex longitudinal cross-sectional shape continuous in the width direction over the entire length of the upper frame member 20.

The convex portion 21a is engaged with the small cutout portion 14b of the vertical frame member 10 at the end side in the width direction (see FIG. 3 ). That is, the convex portion 21a in the horizontal direction is in contact with or close to the upper end portion 11a1 of the convex portion 11a in the vertical direction to form a horizontal shape.

Moreover, when the door and window body A in the open state is fully closed, the protrusion 21a serves as a door stopper for receiving the surface on the closing direction side of the door and window body A (specifically, the upper end side portion of the surface).

The upward plates 22, 22 on both sides are respectively formed into flat plates roughly orthogonal to the inner side plate 21 of the frame, and are continuous in the width direction over the entire length of the upper frame member 20.

Furthermore, the inward plates 23, 23 on both sides are formed as flat plate protrusions that are spaced apart and face each other in the depth direction, and are continuous in the width direction over the entire length of the upper frame member 20.

The inward plates 23, 23 are appropriately spaced in the width direction, and a plurality of positioning pieces 25 are fixed by welding or the like. The positioning pieces 25 are positioned on the side of the main body opening by a fixing member (anchor, etc.) not shown in the figure.

Moreover, the upper frame member 20 formed as above is provided with: an engaged portion 20a engaged with the engaging portion 14a of the vertical frame member 10 to prevent movement in the width direction and the depth direction; and a closing portion 23a to close the opening portion 10a of the vertical frame member 10 at the outer side of the frame than the engaged portion 20a.

The two sides of the embedded part 20a in the depth direction of the upper frame member 20 are respectively formed into slits (or grooves) of the embedded part 14a in the shape of a protruding piece on the frame inner side plate part 21, the upper plate part 22 and the closing part 23a.

In other words, the engaged portion 20a penetrates the inner side plate portion 21, the upward plate portion 22, and the inner plate portion 23 in the U-shaped longitudinal section, and the end portion in the depth direction passes through the frame in the vertical direction.

The closing portion 23a is formed by extending the portion of each inner plate 23 other than the fitted portion 20a toward the outer side of the frame closer to the fitted portion 20a in a flat plate shape. The closing portion 23a is close to or in contact with the upper edge of the vertical frame member 10.

To explain more specifically, the top of the closing portion 23a is approximately flush with the upper end of the vertical frame member 10. Moreover, the protruding end of the frame outer side of the closing portion 23a is close to or in contact with the inner surface of the inner plate portion 13 of the vertical frame member 10 (see Figure 2).

Furthermore, the lower side portion of the closed portion 23a in the upper frame member 20 is a portion extending the frame inner side plate portion 21 and the upper plate portion 22 toward the outer side of the frame, and this portion is located in the opening portion 10a of the vertical frame member 10. In addition, as another example other than the illustrated example, part or all of the aforementioned portion located in the opening portion 10a may be omitted.

The upper frame member 20 of the above-mentioned structure is formed by bending a flat metal plate, and before the bending, the through-slit-shaped fitting portion 20a is formed by pressing or the like.

Furthermore, the vertical frame member 10 and the upper frame member 20 constructed as above are integrally connected via a connector 40 (see FIG. 4 ) disposed at the inner angle portion therebetween.

The connector 40 is a triangular member with a roughly L-shaped cross section, and one portion thereof is fixed to the vertical frame member 10 by welding or the like.

When connecting the vertical frame member 10 and the upper frame member 20, the other part of the connector 40 is connected and fixed to the upper frame member 20 by means of a locator such as a screw. The symbol 20b in FIG. 5 is a hole for inserting the aforementioned locator.

In addition, as another example, the aforementioned other piece of the connector 40 may be connected to the upper frame member 20 by welding.

As another example, the connector 40 may be omitted and the vertical frame member 10 and the upper frame member 20 may be directly connected by a positioner or the vertical frame member 10 and the upper frame member 20 may be directly connected by welding.

In addition, the lower frame member 30 is a member that is vertically symmetrical with the upper frame member 20, and the connection structure with the vertical frame member 10 is also vertically symmetrical.

The lower frame member 30 may also be configured in a manner other than the above-mentioned configuration or may be omitted.

Next, the effects of the features of the door and window 1 are described in detail.

According to the above structure, the connection part between the vertical frame member 10 and the upper frame member 20 is positioned with high precision by the engagement of the engagement part 14a and the engaged part 20a.

Therefore, it is possible to facilitate the operation of connecting and fixing the vertical frame members 10 and the upper frame members 20 by welding or screwing, resulting in good manufacturing operability in the factory and good assembly operability based on the reduction method on site.

Furthermore, if the engaged portion 20a of the upper frame member 20 is engaged with the engaging portion 14a of the vertical frame member 10, the opening portion 10a at the upper end of the vertical frame member 10 can be closed by the closing portion 23a. Therefore, when the door and window frame B is set at the main body opening, the upper end of the vertical frame member 10 is not opened corresponding to the protruding size portion, and as a result, impurities or pests will not invade the opening or contact the operator.

<Variation example>

In addition, in the door and window frame B of the above-mentioned embodiment, the structure of the left and right vertical frame members 10, 10 is applied to the upper frame member, and the structure of the upper frame member 20 is also applied to the left and right vertical frame members. In other words, it is also possible to set the structure of the door and window frame B constructed above to rotate the horizontal angle by 90 degrees to appropriately adjust the longitudinal and transverse dimensions. In this structure, the vertical frame member 10 constructed above is called the upper frame member (or horizontal frame member), and the upper frame member 20 constructed above is called the vertical frame member.

Even in such a case, the end side of the upper frame member of the structure based on the vertical frame member 10 can function as the above-mentioned closing portion. That is, the opening at the upper end of the vertical frame member of the structure based on the upper frame member 20 can be closed by the end side (closing portion) of the upper frame member of the structure based on the vertical frame member 10.

Furthermore, according to the door and window frame B of the above-mentioned embodiment, the convex portion 11a (door stop portion) of the vertical frame member 10 and the convex portion 21a (door stop portion) of the upper frame member 20 are configured in a horizontal state as described above (see FIG. 3 ), but as another example, the two convex portions (door stop portions) may also be configured in a vertical state as in the door and window frame B' shown in FIG. 6 and FIG. 7 .

To explain in detail, in the door and window frame B', the frame inner side plate portion 11 of the vertical frame member 10 has a protrusion 11a' protruding toward the inner side of the frame in the up-down direction, and the upper end portion 11a1' of the protrusion 11a' is flush with the inner edge of the lower side of the cutout portion 14 (see Figure 7).

In other words, the vertical frame member 10 of the door and window frame B' is obtained by omitting the small cutout portion 14b from the vertical frame member 10 of the door and window frame B (see FIG. 3 ) and aligning the upper end portion 11a1' of the protrusion 11a' with the inner edge of the lower side of the cutout portion 14.

In the door and window frame B', a notch 21b' is provided on the frame inner side plate 21 of the upper frame member 20 to engage with the protrusion 11a' of the vertical frame member 10.

In other words, the upper frame member 20 of the door and window frame B' is provided with a cutout portion 21b' relative to the upper frame member 20 of the door and window frame B (see FIG. 3 ).

Furthermore, the convex portion 11a' of the vertical frame member 10 is configured to be vertically fitted with the cutout portion 21b' so that the convex portion 21a of the upper frame member 20 passes upward (see FIG. 6).

Therefore, according to the door and window frame B' shown in Figures 6 and 7, similar to the above-mentioned door and window frame B, on the basis of good assembly workability based on the reduction method in the field, when it is set at the main body opening, it is possible to prevent the formation of an opening at the upper end of the vertical frame member 10 corresponding to the protruding size portion.

In addition, the vertical frame member 10 and the upper frame member 20 of the above-mentioned embodiment are respectively configured to have a substantially C-shaped cross-sectional shape, but as another example, they may also be configured to have a cross-sectional shape of "ㄈ" or "口", an interface without an end ring, or other cross-sectional shapes.

Furthermore, according to the above-mentioned implementation, the above-mentioned door and window frame B is applied to the frame member of the door, but as another example, the above-mentioned door and window frame B can also be applied to the frame member (or center column, etc.) of the door, folding door, balanced door, water-stop door, window sash, screen window, partition partition or shutter device.

Furthermore, according to the above-mentioned implementation, the door and window frame B is constructed as a four-sided frame, but as another example, it can also be constructed as a three-sided frame in which the lower frame member 30 is omitted.

As another example, in a door and window frame having a vertical frame between left and right vertical frame members, the structure can also be applied to close the opening portion at the upper end of the vertical frame.

Furthermore, the present invention is not limited to the above-mentioned implementation modes and can be appropriately modified within the scope that does not change the gist of the present invention.
