Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to fittings such as a stepped window and a continuous window, which are provided with two frames having frames on all four sides, and in which the two frames are arranged side by side with the adjacent frames connected to each other. .

The fittings include a so-called stepped window configured by combining frames vertically and a continuous window configured by combining frames horizontally. When combining frames, a structural member is interposed between adjacent frames, and each frame is connected to the structural member. For example, when a stepped window is constructed by combining frames vertically, a structural member is interposed between the lower frame of the frame positioned above and the upper frame of the frame positioned below. The lower frame and the upper frame are connected to each other (for example, see Patent Document 1).

JP 2015-108272 A

By the way, when the adjacent lower frame and upper frame are connected via a structural member, not only can the facing surface of the structural member be visible from the inside of the room, but also the boundary between the structural member and the lower frame and the structural member and the upper frame can also be visually recognized from the inside of the room. For this reason, when considering the appearance quality of fittings, it is preferable to cover the area from the lower frame of the frame located above to the upper frame of the frame located below with a cover member.

Here, in fittings, it is common to use aluminum alloys or resin materials that are extruded as frames and stiles, which are components of fittings. Therefore, it is preferable to apply an extrusion molded product also for the cover member. However, in fittings that connect the lower frame and the upper frame via structural members, the dimension from the upper lower frame to the lower upper frame is extremely large, so a large cover member is required. Therefore, considering the production cost and extrusion moldability, it is not necessarily preferable. In particular, resin materials are often used for parts of fittings located on the indoor side in consideration of heat insulation and design. Therefore, when the cover member is extruded from a resin material, there is a concern that the above-mentioned problems will become more pronounced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide fittings capable of improving the appearance quality of mutually connected frames without causing problems of manufacturing cost and formability.

In order to achieve the above object, a fitting according to the present invention is a fitting provided with two frame bodies having frames on all four sides, wherein the two frame bodies are arranged side by side with the adjacent frames being connected to each other. each of the frames connected to each other is provided with a cover mounting piece at a position corresponding to each other, and each of the cover mounting pieces is provided with a cover mounting portion having the same position in the prospective direction, A first cover member is attached to the cover attachment piece via the cover attachment portion on one of the adjacent frames, and a second cover member is attached to the cover attachment piece via the cover attachment portion on the other of the adjacent frames. A cover member is attached, the first cover member and the second cover member having a prospective extension extending in a prospective direction and extending along the prospective direction from an extending edge of the prospective extension. and a rear extension portion covering the rear surface of the frame facing the inside of the chamber, connected to the cover mounting piece via the rear projection portion, and the extension edge portion of the rear extension portion being connected by a connecting member. The first cover member and the second cover member are connected to each other, and are formed such that at least the prospective extension and the prospective extension have the same cross-sectional shape as each other. .

According to the present invention, since the facing surfaces of the mutually connected frames are covered by the mutually connected first cover member and the second cover member, the first cover member and the second cover member are separately molded. It is possible to cover the facing surfaces of interconnected frames without incurring manufacturing cost or formability problems.

Here, the projected direction is a direction along the depth of the fittings, as indicated by an arrow A in the drawing. A surface along the prospective direction may be referred to as a prospective surface. In this embodiment, the term "finding direction" is also used. In the case of items such as the upper frames 12 and 22 and the lower frames 13 and 23 that extend along the horizontal direction, the viewing direction is a vertical direction orthogonal to the viewing direction. In the case of vertical frames 11, 21, etc., which extend along the vertical direction, the horizontal direction perpendicular to the viewing direction is called the viewing direction. A plane along the viewing direction may be referred to as a viewing plane.

As shown in FIGS. 4 and 5, the lower frame 13 constituting the upper frame 10 and the upper frame 22 constituting the lower frame 20 have nail fins 13a, 22a and cover mounting pieces 13b, 22b, respectively. is provided. The nail fin portions 13a and 22a are plate-shaped portions extending from the outer peripheral portions of the lower frame 13 and the upper frame 22 along the viewing direction to the outer peripheral side. These nail fins 13a and 22a serve as connecting parts to the frame when the frames 10 and 20 are used alone. That is, the nail fins 13a and 22a are superimposed on the surface of the building body facing the outside of the room and are screwed or nailed to support the lower frame 13 and the upper frame 22 on the building body. . In the present embodiment, when the two frames 10 and 20 are vertically arranged so that the positions of the vertical frames 11 and 21 along the direction of projection match each other, the vertical frames 11 and 21 are positioned on the same plane. Nail fillets 13a and 22a are provided on the frame 13 and the upper frame 22, respectively.

The cover mounting pieces 13b and 22b are plate-like portions that extend toward the interior of the room from the viewing surfaces of the lower frame 13 and the upper frame 22 that face the interior of the room. These cover attachment pieces 13b and 22b are portions to be connected to the picture frame when the respective frames 10 and 20 are used alone. have. The positions of the screw insertion holes 13b1 provided in the cover mounting piece 13b of the lower frame 13 and the screw insertion holes 22b1 provided in the cover mounting piece 22b of the upper frame 22 are aligned with each other along the projection direction of the vertical frames 11 and 21, In addition, when the two frames 10 and 20 are vertically aligned with the left and right positions aligned, they are formed so as to face each other.

A connecting structural member 30 and a cover 40 are arranged between the upper lower frame 13 and the lower upper frame 22 having the above-described structure. The connecting structural member 30 is for connecting between the lower frame 13 and the upper frame 22, and is made of steel. In this embodiment, a connecting structural member 30 having a rectangular cylindrical shape is applied.

To this connection structural member 30, the connecting screw S1 is screwed together with the nail fin portion 13a of the lower frame 13 and the nail fin portion 22a of the upper frame 22 in contact with the facing surface facing the outside of the room. The frame 13 and the upper frame 22 are connected. In other words, by connecting the lower frame 13 and the upper frame 22 to the connecting structural member 30, the upper frame 10 and the lower frame 20 are in a state where the positions along the projection direction of the vertical frames 11 and 21 are aligned with each other. are interconnected with each other. Although not shown in the drawing, the connecting screw S1 is screwed at a plurality of positions along the length of the nail fins 13a and 22a.

The cover 40 covers a portion of the connecting structural member 30 exposed to the interior side, a boundary portion between the connecting structural member 30 and the upper lower frame 13, and a boundary portion between the connecting structural member 30 and the lower upper frame 22. It has a first cover member 40A attached to the upper lower frame 13 and a second cover member 40B attached to the lower upper frame 22. As shown in FIG. The first cover member 40A and the second cover member 40B are extruded members molded from a resin material, and are configured to have a substantially uniform cross-sectional shape over the entire longitudinal length. In the present embodiment, a first cover member 40A and a second cover member 40B each having the same cross-sectional shape and having a prospective extension portion 41 and a prospective extension portion 42 are applied. The prospective extension part 41 extends substantially horizontally along the prospective direction. The edge portion of the prospective extension portion 41 located on the exterior side contacts the inner surfaces 13b2 and 22b2 of the cover attachment pieces 13b and 22b, and the cover is attached by the attachment screws S2 screwed through the screw insertion holes 13b1 and 22b1. It is attached to the pieces 13b, 22b. The bottom extension portion 42 is bent substantially at a right angle from the extension edge of the projection extension portion 41 and extends vertically. The extension dimension of the bottom extending portion 42 is approximately 1/2 of the distance between the cover mounting piece 13b provided on the upper lower frame 13 and the cover mounting piece 22b provided on the lower upper frame 22. As shown in FIG.

As is clear from the drawing, the first cover member 40A has a prospective extension portion 41 extending downward from the prospective extension portion 42, while the second cover member 40B has a prospective extension portion 41 and upwardly extending therefrom. A facing extension 42 extends toward. The extension edges of these extension extensions 42 are in contact with each other without gaps, and are connected to each other by connection members 43 .

Hereinafter, detailed configurations of the first cover member 40A, the second cover member 40B, and the connecting member 43 will be described with appropriate reference to FIGS. As described above, since the first cover member 40A and the second cover member 40B have the same cross-sectional shape, only the first cover member 40A will be described, and the second cover member 40B will be described. Suppose that the same code|symbol is attached.

The prospective extension portion 41 of the first cover member 40A has a plurality of hollow portions 41a and is configured in a thick plate shape. A mounting piece accommodation recess 41b and a threaded groove 41c are provided in a portion of the prospective extension portion 41 with which the cover mounting piece 13b (22b) abuts. The mounting piece accommodating recess 41b is a recess for eliminating a step between the cover mounting piece 13b (22b) and the projected extension portion 41 when the cover mounting piece 13b (22b) is brought into contact with the cover mounting piece. It is formed to a depth corresponding to the plate thickness of 13b (22b). The threaded groove 41c is formed along the length of the prospective extension portion 41 and opens into the mounting piece accommodation recess 41b. Further, a plate-like portion 41d is provided in the intermediate portion of the prospective extension portion 41. As shown in FIG. The plate-like portion 41d has a single plate-like shape, is a portion that connects adjacent hollow portions 41a, and is formed along the outer surface of the hollow portion 41a.

The bottom extension portion 42 of the first cover member 40A, like the projection extension portion 41, has a plurality of hollow portions 42a and is configured in a thick plate shape. It has a piece 42c and an engaging groove 42d. The connecting pieces 42b are plate-like portions that are connected to each other by a connecting member 43, which will be described later. In the present embodiment, there are provided a plate-like connecting board portion 42b1 extending in the projection direction along the outer surface of the hollow portion 42a, and a clamping piece portion 42b2 provided on the extending edge portion of the connecting board portion 42b1. A connecting piece 42b is formed by doing so. The clamping piece portion 42b2 is bent from the extending edge portion of the connecting board portion 42b1 toward the outdoor side and then bent so as to bulge toward the prospective extension portion 41 . The engaging piece 42c is a plate-like portion extending parallel to the connecting substrate portion 42b1. In the present embodiment, an engagement piece 42c is provided at a portion that is closer to the interior than the inner surface of the hollow portion 42a. The engagement groove 42d is formed along the length of the extension portion 42 and opens at a portion of the extended end surface of the hollow portion 42a that is located outside the engagement piece 42c.

The connecting member 43 is integrally formed of metal such as steel, and has an engaging plate portion 43a, two restraining plate portions 43b, and two clamping plate portions 43c. The engaging plate portion 43a has a flat plate shape with a plate thickness that can be inserted into the engaging groove 42d, and is configured to have different lengths in the vertical and horizontal directions. The dimension of the long side is slightly shorter than twice the distance from the tip edge of the connecting piece 42b to the engaging groove 42d. The dimension of the short side is configured to be shorter than twice the distance from the tip edge of the connecting piece 42b to the engaging piece 42c. Slanted surfaces 43d parallel to each other are provided at one diagonal corner of the engaging plate portion 43a. The two restraining plate portions 43b are formed by cutting and raising the engaging plate portions 43a in the same direction. More specifically, the restraining plate portion 43b is bent from the engaging plate portion 43a and then extended parallel to the engaging plate portion 43a. A gap is secured so that the can be fitted almost without a gap. These two restraining plate portions 43b extend away from each other toward the short side from a portion close to the center of gravity position C of the engaging plate portion 43a. A space shorter than twice the distance from the tip edge of the connecting piece 42b to the engaging piece 42c is secured between the restraining plate portions 43b. The two clamping plate portions 43c are rectangular plate-like portions that are bent in a direction opposite to the pressing plate portion 43b from an edge located on the long side of the engaging plate portion 43a. The clamping plate portions 43c are provided at portions opposite to each other with respect to an imaginary bisecting plane α that bisects the length of the engaging plate portion 43a. Between the clamping plate portions 43c, a space larger than twice the distance from the tip edge of the connecting piece 42b to the bulging portion of the clamping piece portion 42b2 is secured. As is clear from the drawing, the engaging plate portion 43a, the two restraining plate portions 43b, and the two clamping plate portions 43c of the connecting member 43 described above form rotationally symmetrical shapes about the center of gravity position C of the engaging plate portion 43a. Each is formed as follows.

In the first cover member 40A and the second cover member 40B constructed as described above, as shown in FIG. are kept connected to each other. That is, as shown in FIG. 6, with the connecting pieces 42b of the first cover member 40A and the second cover member 40B opposed to each other, the length of the engaging plate portion 43a extends along the length of the first cover member 40A and By arranging the connecting member 43 so that the holding plate portion 43c faces the connecting piece 42b, the engaging plate portion 43a can be inserted between the engaging pieces 42c. At this time, the clamping piece portion 42b2 of the connecting piece 42b is arranged between the two clamping plate portions 43c. Therefore, when the connecting member 43 is rotated clockwise in FIG. 6B from this state, the engaging piece 42c is fitted between the engaging plate portion 43a and the restraining plate portion 43b as shown in FIG. Therefore, the connecting member 43 is maintained in a state of being engaged between the first cover member 40A and the second cover member 40B, and the holding piece portion 42b2 of the first cover member 40A and the second cover member 40B are held. The piece portion 42b2 is held between the two holding plate portions 43c. As a result, the first cover member 40A and the second cover member 40B are kept connected to each other, and the cover 40 is constructed.

As described above, the dimension of the first cover member 40A along the viewing direction is approximately the distance between the cover attachment piece 13b provided on the upper lower frame 13 and the cover attachment piece 22b provided on the lower upper frame 22. 1/2. Therefore, the cover 40, which includes the first cover member 40A and the second cover member 40B connected by the connecting member 43, has a dimension along the viewing direction of the cover attachment piece 13b provided on the upper lower frame 13 and the lower upper frame 13. 22 is substantially equal to the mutual interval with the cover mounting piece 22b. As a result, when the mounting screws S2 are screwed into the screw grooves 41c of the prospective extensions 41 through the screw insertion holes 13b1 and 22b1 of the respective cover mounting pieces 13b and 22b, the chambers of the connecting structural member 30 are secured by the cover 40. The part exposed to the inside, the boundary part between the connecting structural member 30 and the facing surface 13c of the lower frame 13 facing the room, and the boundary part between the connecting structural member 30 and the facing face 22c of the upper frame 22 facing the room are covered without gaps. It is possible to improve the appearance quality of fittings.

Moreover, since the cover 40 is formed by connecting the first cover member 40A and the second cover member 40B as described above, a large mold is required even when the resin material is extruded. Therefore, not only is it advantageous in terms of manufacturing cost, but it is also favorable in terms of moldability. Furthermore, in the embodiment, since the first cover member 40A and the second cover member 40B have the same cross-sectional shape, only one mold is required for extrusion molding, which reduces the manufacturing cost. It becomes possible to plan

Furthermore, since the plate-like portions 41d are provided in the prospective extension portions 41 of the first cover member 40A and the second cover member 40B, they can be easily bent via the plate-like portions 41d. Therefore, even if there is a molding error in the first cover member 40A or the second cover member 40B, for example, the screw insertion holes 13b1 and 13b1 of the cover mounting pieces 13b and 22b can be opened by appropriately bending the plate-like portion 41d. The screw groove 41c can be easily matched with 22b1, and the mounting work can be facilitated. Moreover, since high molding accuracy is not required for the first cover member 40A and the second cover member 40B, it is advantageous in terms of manufacturing cost.

Incidentally, as shown in FIGS. 4 and 7, the fore end face of the cover 40 is covered by a series of frames 50 arranged over the vertical frames 11 and 21, so that it is visible from the outside. There is no Also, between the lower frame 13 and the upper frame 22, a gap is formed in a portion on the exterior side of the nail fins 13a and 22a, which can be closed by filling the sealing material 60. It is possible, and there is no possibility that the nail fin portions 13a and 22a and the connecting structural member 30 will be visually recognized.

In the above-described embodiment, the connection member 43 is exemplified by one that maintains the state of connection between the first cover member 40A and the second cover member 40B by simply rotating the connection member 43, but the present invention. is not necessarily limited to this.
For example, as in Modified Example 1 shown in FIGS. 9 and 10, a connecting member 143 having an engaging plate portion 143a and two clamping plate portions 143b is applied, and after a rotational operation, the engaging piece 42c is engaged. A screw S3 may be screwed into the plywood portion 143a.

Moreover, as shown in Modified Example 2 of FIG. That is, a connecting member 243 having elastic pinching pieces 243b that can be elastically expanded is applied to both side edges of a plate-shaped clip base 243a. By clamping the clamping piece portion 42b2 and the clamping piece portion 42b2 of the second cover member 40B, the work of connecting the first cover member 40A and the second cover member 40B can be facilitated.

Furthermore, as in Modified Example 3 of FIG. 12, a connecting member 343 having a simple shape in which both side edges are simply bent or a connecting member (not shown) having a simple flat plate shape is applied to engage the first cover member 40A. The screw S4 may be screwed into the connecting member 343 via the mating piece 42c and the engaging piece 42c of the second cover member 40B. By applying such a simply-shaped connecting member 343, the manufacturing cost of the connecting member 343 can be reduced.

Modifications 1 to 3 described above are different in the configuration of connecting members 143, 243, and 343, and the rest of the configuration is the same as in the embodiment. Accordingly, in Modifications 1 to 3, the same reference numerals are assigned to the same components as in the embodiment.
