Description

This invention relates to a joinery component, specifically one having a cover member on its surface, with a cap provided between the cover member and a mating member positioned opposite the end face of the cover member.

In joinery, some profiles have cover members attached to the surface facing the interior. Caps are fitted to the ends of the cover members to seal the gap between them and mating components such as picture frames (see, for example, Patent Document 1).

Japanese Patent Publication No. 2001-193358

By the way, the cap in Patent Document 1 is supported by the frame by fitting it onto the end of the profile. Therefore, if there are dimensional or assembly errors in the profile, there is a concern that a gap may form between the cap and the mating member.

In view of the above circumstances, the present invention aims to provide a joinery component that can eliminate gaps between the mating member and the cap, without being affected by dimensional or assembly errors in the profiled material.

To achieve the above objective, the joinery according to the present invention comprises a profile with a cover member, the cover member having a cap between it and a mating member positioned opposite the end of the cover member, and at least one of the cover member and the cap is provided with a biasing member that biases the cap toward the mating member relative to the cover member.

According to this invention, since a biasing member is provided between the cover member and the cap, it is not affected by dimensional errors or assembly errors in the profiled material. Furthermore, because the biasing member biases the cap relative to the cover member, there is no concern that a gap will form between the mating member and the cap even if there are dimensional or assembly errors in the cover member.

The following describes in detail preferred embodiments of the joinery according to the present invention, with reference to the attached drawings. For convenience, the terms "depth direction" and "face direction" may be used below. The depth direction is the direction along the depth of the joinery, as indicated by arrow A in the figure. The surface along the depth direction may be referred to as the depth surface. The face direction, in the case of elements extending horizontally, such as bottom frames, is the direction along the vertical axis perpendicular to the depth direction. In the case of elements extending vertically, such as vertical frames, the face direction is the direction along the horizontal axis perpendicular to the depth direction. The surface along the face direction may be referred to as the face surface.

Figures 1 to 7 show a joinery that is an embodiment of the present invention. The joinery illustrated here is a stepped window, in which an upper vertical sliding window (window section) and a lower fixed window (window section) are constructed within a single frame 10. The frame 10 is constructed by assembling an upper frame 11, a lower frame 12, and left and right vertical frames 13 around the perimeter, and by spanning a transom (profile) 14 between the left and right vertical frames 13 along the left-right direction.

A vertical sliding window is constructed by supporting a sash 20 in an openable and closable manner within an upper frame section 10A, which consists of an upper frame 11, a transom 14, and left and right vertical frames 13. The sash 20 is constructed by attaching an upper frame 22, a lower frame 23, and left and right vertical frames 24 around an upper panel 21, such as a double-glazed glass panel. In the illustrated example, link mechanisms 1, called friction stays, are provided between the upper frame 11 and the upper frame 22, and between the transom 14 and the lower frame 23, allowing the sash 20 to be opened so that it protrudes outwards. A fixed window is constructed by attaching a lower panel 15, such as a double-glazed glass panel, to a lower frame section 10B, which consists of a transom 14, a lower frame 12, and left and right vertical frames 13.

The upper frame 11, lower frame 12, vertical frame 13, and transom 14 that constitute the frame body 10 are each composed of an exterior metal frame section 11A, 12A, 13A, and 14A, which are extruded profiles formed from a metal such as aluminum alloy, and an interior resin frame section 11B, 12B, 13B, and 14B, which are extruded profiles formed from resin.

Of these, the metal frame portion 13A of the vertical frame 13 is constructed by connecting the outer metal outer frame member 13A1 on the outer circumference side with the inner metal frame members 13A2 and 13A3 on the inner circumference side. The outer metal frame member 13A1 is a continuous piece between the upper frame 11 and the lower frame 12, and the upper frame portion 10A and the lower frame portion 10B have the same cross-sectional shape. In contrast, the inner metal frame members 13A2 and 13A3 are divided vertically at the transom 14, and the upper frame portion 10A and the lower frame portion 10B are configured to have different cross-sectional shapes. That is, the inner metal frame member 13A2 of the upper frame portion 10A has a cross-sectional shape corresponding to a vertical sliding window, and the inner metal frame member 13A3 of the lower frame portion 10B has a cross-sectional shape corresponding to a fixed window. Similarly, the resin frame portion 13B of the vertical frame 13 is divided vertically at the transom 14. The upper resin frame material 13B1 of the upper frame portion 10A has a cross-sectional shape corresponding to a vertical sliding window, while the lower resin frame material 13B2 of the lower frame portion 10B has a cross-sectional shape corresponding to a fixed window.

The resin frame portion 11B of the upper frame 11, the resin frame portion 12B of the lower frame 12, and the resin frame portion 13B of the vertical frame 13 each have outer peripheral mounting plate portions 11a, 12a, and 13a that extend in the depth direction toward the interior of the room. These are connected to the interior frame (mating member) 2 by screwing in screw members S1 via the outer peripheral mounting plate portions 11a, 12a, and 13a. The frame 2 is, for example, a thick plate formed from wood, and is attached to a structure (not shown) in a manner that protrudes further into the room than the outer peripheral mounting plate portions 11a, 12a, and 13a.

The resin frame portion 14B of the transom 14 is composed of an upper frame cover member 14B1, a lower frame cover member 14B2, and an inner cover member (cover member) 14B3. The upper frame cover member 14B1 is provided on the upper frame portion 10A and is positioned on the interior side of the sash 20, which is positioned in the closed position, on the metal frame portion 14A of the transom 14. The lower frame cover member 14B2 is provided on the lower frame portion 10B and is positioned on the interior side of the lower panel 15, on the metal frame portion 14A of the transom 14. More specifically, the upper frame cover member 14B1 and the lower frame cover member 14B2 are provided with an engaging piece 14a and a cover mounting plate portion 14b, respectively, and the metal frame portion 14A of the transom 14 is provided with an engaging groove 14c in the portion corresponding to the engaging piece 14a. The upper frame cover member 14B1 and the lower frame cover member 14B2 are supported on the metal frame portion 14A of the transom 14 by engaging the engaging piece 14a with the engaging groove 14c. The cover mounting plate portion 14b is provided so as to protrude further into the room than the metal frame portion 14A of the transom 14, and its position in the depth direction corresponds to the outer peripheral mounting plate portions 11a, 12a, and 13a.

The inner cover member 14B3 covers the visible surface of the metal frame portion 14A of the transom 14 that faces the interior of the room, and is provided between the cover mounting plate portion 14b of the upper frame cover member 14B1 and the cover mounting plate portion 14b of the lower frame cover member 14B2. More specifically, as shown in Figure 8, the inner cover member 14B3 is configured to be symmetrical in shape vertically, and has a main cover plate portion 16a, two screw receiving portions 16b, and a back plate portion 16c. The main cover plate portion 16a is a flat plate that extends along the visible direction. The dimensions of the main cover plate portion 16a along the vertical direction are larger than the metal frame portion 14A of the transom 14, and are configured to span the width between the cover mounting plate portion 14b of the upper frame cover member 14B1 and the cover mounting plate portion 14b of the lower frame cover member 14B2. The screw receiving portions 16b extend outwards from both the upper and lower edges of the main cover plate portion 16a. In the illustrated example, the screw receiving portions 16b are provided in a hollow shape with openings at both end faces. Engaging notches 16d are provided on the opposing inner surfaces of the two screw receiving portions 16b. The engaging notches 16d have a rectangular opening, with an engaging surface 16e on the outer periphery. The engaging surface 16e is a plane extending in a direction perpendicular to the longitudinal direction of the inner cover member 14B3. The backing plate portion 16c is a flat plate positioned parallel to the main cover plate portion 16a, on the outside of the main cover plate portion 16a, and is located between the opposing inner surfaces of the two screw receiving portions 16b.

The inner cover member 14B3 is positioned between the upper frame cover member 14B1 and the lower frame cover member 14B2 by overlapping the cover mounting plate portion 14b of the upper frame cover member 14B1 and the cover mounting plate portion 14b of the lower frame cover member 14B2 onto the screw receiving portion 16b, and then screwing the screw member S2 into the screw receiving portion 16b via the cover mounting plate portion 14b. As described above, the resin frame portion 13B of the vertical frame 13 is divided vertically at the transom 14 by the upper resin frame material 13B1 provided on the upper frame portion 10A and the lower resin frame material 13B2 provided on the lower frame portion 10B. Therefore, the inner cover member 14B3 is positioned so that both end faces face the inner circumference surface 2a of the picture frame 2. The dimensions of the inner cover member 14B3 along its longitudinal side are set so that there is a gap between its end face and the inner circumferential surface 2a of the left and right frame 2. Caps 30 are provided between both end faces of the inner cover member 14B3 and the inner circumferential surface 2a of the frame 2 to close the aforementioned gaps.

The cap 30 is molded, for example, from resin, and is configured to be shared on both the left and right sides of the inner cover member 14B3. As shown in Figure 9, the cap 30 is configured to be symmetrical vertically to correspond to the inner cover member 14B3, and has a cap body 30a, an inner surface guide portion (guide portion) 30b, an outer surface guide portion (guide portion) 30c, and two edge guide portions (guide portions) 30d.

The cap body 30a is a flat plate shape with dimensions that allow it to be positioned opposite the end face of the inner cover member 14B3. More specifically, the cap body 30a has an intermediate base portion 31a, two wide portions 31b, two support plate portions 31c, and two narrow portions 31d. The intermediate base portion 31a is a flat plate shape with a width that allows it to cover the end face of the main cover plate portion 16a and the end face of the back plate portion 16c. The dimensions of the intermediate base portion 31a along its vertical axis are configured such that the upper edge overlaps the upper screw receiving portion 16b, and the lower edge overlaps the lower screw receiving portion 16b. The two wide portions 31b protrude outwards from both the upper and lower ends of the outdoor-side edge of the intermediate base portion 31a. Each wide portion 31b is configured such that its protruding edge toward the outdoor side is positioned approximately midway between the screw receiving portions 16b. The two support plate portions 31c extend outward from the outdoor-facing edge of the wide portion 31b and are positioned between the two screw receiving portions 16b. The two narrow portions 31d extend along the visible direction from the portions located on the indoor side of both the upper and lower ends of the intermediate base portion 31a and are configured to have a width sufficient to cover the end face of the main cover plate portion 16a.

The inner and outer guide portions 30b and 30c extend from both side edges of the cap body 30a, approximately parallel to each other. The inner guide portion 30b extends from the portion between the wide portions 31b on the outdoor side edge of the intermediate base portion 31a. The outer guide portion 30c extends from the indoor side edges of the intermediate base portion 31a and the narrow portion 31d. The extension dimension of the outer guide portion 30c is set to be shorter than that of the inner guide portion 30b.

The edge guide portion 30d extends outward from both the upper and lower edges of the outer surface guide portion 30c, and is configured to cover the upper and lower edges of the main cover plate portion 16a. The outer peripheral edge of the edge guide portion 30d is connected to the narrow portion 31d.

Furthermore, the cap 30 has hook portions 32 on each of the two support plate portions 31c, and notches 33 and leaf spring portions (biasing members) 34 on each of the two wide portions 31b. The hook portions 32 protrude substantially horizontally from the upper edge of the upper support plate portion 31c and the lower edge of the lower support plate portion 31c, respectively, in the same direction as the outer surface guide portion 30c. Hook claws 32a are provided at the protruding ends of the hook portions 32. The hook claws 32a are protrusions provided on the surfaces of the hook portions 32 that are on the outer circumference side of each other. The protruding dimension of the hook claws 32a is configured to gradually increase toward the base end side of the hook portion 32. The upper hook claw 32a and the lower hook claw 32a are set so that the mutual width dimension at the tip side is smaller than the mutual distance between the two screw receiving portions 16b, and the mutual width dimension at the base end side is larger than the mutual distance between the two screw receiving portions 16b. The distance from the base end of the hook portion 32 to the hook claw 32a is set to be greater than the distance from the end face of the inner cover member 14B3 to the engagement surface 16e. The notch 33 is a square-shaped through-hole formed in the portion extending from the intermediate base portion 31a to the wide portion 31b. The leaf spring portion 34 is a rectangular flat plate that protrudes from the inner peripheral edge of the notch 33 in the same direction as the outer surface guide portion 30c. The protrusion dimension of the leaf spring portion 34 is set to gradually increase toward the outer circumference. This leaf spring portion 34 can elastically deform when an external force is applied, reducing its protrusion dimension from the wide portion 31b. In the unloaded state, the leaf spring portion 34 protrudes to its maximum extent from the wide portion 31b, and the distance from the protruding edge to the outer peripheral end face of the hook claw 32a is set to be smaller than the distance from the end face of the inner cover member 14B3 to the engagement surface 16e.

When the cap 30 described above is inserted between the two screw receiving portions 16b with the outer guide portion 30c aligned with the surface of the main cover plate portion 16a, the hook claws 32a come into contact with the screw receiving portions 16b, causing the hook portions 32 to elastically deform toward each other. Subsequently, when the cap 30 is moved further in the insertion direction, as shown in Figure 10, the hook portions 32 return to their original state due to elastic restoring force when the hook claws 32a pass the engagement surface 16e, resulting in the hook claws 32a being inserted into the engagement notch 16d. As a result, the hook claws 32a face the engagement surface 16e, restricting the movement of the cap 30 toward detachment from the inner cover member 14B3.

During this time, the leaf spring portion 34 provided on the cap 30 abuts against the end face of the back plate portion 16c against the inner cover member 14B3, and becomes elastically deformed as the hook claw 32a passes the engagement surface 16e. Therefore, when the external force moving the cap 30 in the insertion direction is removed from the above state, the elastic restoring force of the leaf spring portion 34 biases the cap 30 toward detachment relative to the inner cover member 14B3, causing the hook claw 32a to abut against the engagement surface 16e, and maintaining the state in which the cap 30 is attached to the inner cover member 14B3. As a result, the inner cover member 14B3 with caps 30 attached to both ends can be handled as a single component, which is advantageous in terms of handling.

In the joinery frame 10 in which the cap 30 is provided on the inner cover member 14B3 as described above, if, for example, the frame 2 is already attached to the building structure, by bringing the cap 30 into contact with the inner circumferential surface 2a of the frame 2, the leaf spring portion 34 will elastically deform appropriately, making it possible to attach the inner cover member 14B3 to the building structure without creating a gap between the inner cover member 14B3 and the frame 2. On the other hand, it is also possible to attach the frame 2 after the joinery is attached to the building structure. In this case, by bringing the frame 2 into contact with the cap 30, the leaf spring portion 34 will elastically deform appropriately, making it possible to attach the frame 2 to both ends of the inner cover member 14B3 without any gaps. The above-mentioned effects can be achieved without being affected even if there are dimensional errors or assembly errors in the inner cover member 14B3 or the cap 30, because the amount of elastic deformation of the leaf spring portion 34 will change appropriately to adjust for these errors. Of course, since the cap 30 does not hold the metal frame portion 14A of the transom 14, it is not affected even if there are dimensional or assembly errors in the metal frame portion 14A. Moreover, when the cap 30 is in contact with the frame 2, the leaf spring portion 34 is elastically deformed, in other words, the leaf spring portion 34 biases the cap 30 toward the frame 2 relative to the inner cover member 14B3. As shown in Figure 12, even if the inner cover member 14B3 shrinks relative to the metal frame portion 14A due to the effects of heat, there is no concern that a gap will form between the frame 2 and the cap 30. That is, if the inner cover member 14B3 shrinks by a dimension d from the state shown in Figure 12(a), the biasing force of the leaf spring portion 34 moves the cap 30 to protrude toward the frame 2 relative to the inner cover member 14B3 each time. As a result, as shown in Figure 12(b), there is no risk of a gap forming between the cap 30 and the frame 2, and the appearance quality is prevented from being compromised. When the cap 30 moves relative to the inner cover member 14B3 due to the biasing force of the leaf spring portion 34, the inner surface guide portion 30b, the outer surface guide portion 30c, and the edge guide portion 30d each act as guides. Therefore, the cap 30 moves only along the longitudinal direction of the inner cover member 14B3, preventing problems such as the cap 30 shifting in the transverse direction.

In the embodiments described above, an example is shown in which the inner cover member 14B3, which is disposed on the surface of the transom 14, is the target for attachment of the cap 30. However, the present invention is not limited to this. For example, the cover member of the mullion that spans vertically between the upper frame and the lower frame may be the target for attachment of the cap, or other profiles besides transoms and mullions, i.e., the upper frame, lower frame, and vertical frame, may be the target for attachment of the cap. In these cases, the specific shape of the cover member and the specific shape of the cap are not limited to those shown in the embodiments. Also, although a picture frame 2 is given as an example of a mating member, it does not necessarily have to be a picture frame 2. Any other member that is positioned opposite the end of the profile may be used. In this case, it is not necessarily required to attach caps to both ends of the profile. Furthermore, in the above-described embodiment, when the mating member is the picture frame 2, the outer peripheral mounting plate portion 13a provided on the resin frame portion 13B of the vertical frame 13 is brought into contact with the inner peripheral surface 2a. However, as shown in the modified examples in Figures 13 and 14, the outer peripheral mounting plate portion 13a of the resin frame portion 13B may be positioned in the recess 2b provided in the picture frame 2. Additionally, while a leaf spring portion 34 integrally molded with the cap 30 is exemplified as the biasing member, it is not necessary for it to be integral with the cap 30, nor is it necessary for it to be in the shape of a leaf spring. The biasing member may also be provided on the cover member. In this case as well, the biasing member does not necessarily need to be integral with the cover member.

As described above, the joinery according to the present invention is a joinery in which a profile comprises a cover member, and the cover member is provided with a cap between it and a mating member positioned opposite the end of the cover member, and at least one of the cover member and the cap is provided with a biasing member that biases the cap toward the mating member relative to the cover member.
According to this invention, since a biasing member is provided between the cover member and the cap, it is not affected by dimensional errors or assembly errors of the profiled material. Moreover, because the biasing member biases the cap toward the mating member relative to the cover member, there is no concern that a gap will form between the mating member and the cap even if there are dimensional errors or assembly errors in the cover member.

Furthermore, in the above-described joinery, the present invention is characterized in that the profile is a mullion or transom provided between adjacent window sections, the cover member covers the interior surface of the profile, and the cap is provided between the cover member and a frame provided on the interior side of the frame, with the frame being the mating member.
According to this invention, the gap between the cover member, which is installed on the mullion or transom, and the picture frame can be sealed with a cap.

Furthermore, the present invention is characterized in that, in the above-described joinery, the biasing member is integrally provided with the cap.
According to this invention, it is possible to prevent a gap from forming between the mating member and the cap without increasing the number of parts.

Furthermore, the present invention is characterized in that, in the above-described joinery, the cap has a cap body positioned opposite the end face of the cover member, and a leaf spring portion that extends inclined in a direction gradually approaching the end face of the cover member from the cap body, and functions to bias the cap body toward the mating member by contacting the end face of the cover member.
According to this invention, the biasing force of the leaf spring portion provided on the cap maintains the gap member in contact with the mating member.

Furthermore, the present invention is characterized in that, in the above-described joinery, the cap is provided with a guide portion that guides the relative movement of the cover member along its longitudinal direction.
According to this invention, the cap material moves only along the longitudinal side of the cover member because it is guided by the guide portion.

Furthermore, the present invention is characterized in that, in the above-described joinery, the cap is provided with a hook portion that engages with the cover member when moved toward the mating member, thereby restricting longitudinal movement due to the biasing force of the biasing member.
According to this invention, the biasing force of the biasing member keeps the hook portion engaged with the cover member, making it possible to attach the cap to the cover member in advance.
