Summary of the Invention

Problems to be Solved by the Invention

[0004] In the frames disclosed in Patent Documents 1 to 3, the frame members constituting each side of the frame are joined to each other by fastening such as screwing (see, for example, FIGS. 2 and 3 of Cited Document 1). In order to perform such screwing, screw receiving portions (such as a screw pocket 26N) are formed in the frame members (see, for example, FIG. 4 of Cited Document 1). In the frame members of Patent Documents 1 to 3, this screw receiving portion is formed at the central portion of the frame member (the center of the frame member in the thickness direction of the panel body). Here, if the screw receiving portion is formed in the center of the frame member, for example, even if the upper frame member is installed in the opposite direction, there will be little difference in appearance compared to when it is installed correctly (it may be difficult to notice the difference in installation direction). There is no problem if there are no restrictions on the installation direction of the frame member, but if there are restrictions on the installation direction of the frame member, such as the glass groove not being in the center, then if the incorrect installation direction goes unnoticed and the frame member is assembled into the panel body as is, a defective product will be manufactured.

[0005] In view of the above, the present invention aims to provide a frame structure composed of a plurality of frame members joined together, which can reduce the likelihood of incorrect mounting orientation of the frame members (making it easier to notice the mistake).

[Modes for carrying out the invention]

[0018] The embodiments of the present invention will be described in detail below with reference to the drawings. Note that the following embodiments are merely examples of how the present invention can be implemented, and do not limit the present invention to their scope.

[0019] Figure 1 is a schematic diagram showing a door as an example of a panel body using the frame of an embodiment according to the present invention, and Figure 2 is a front view showing the frame of this embodiment (without the trim attached to the lower frame member). The frame 1 of this embodiment is a frame for holding a fitted member 200 such as glass or louver member attached to the panel body 100, and is composed of a plurality of frame members (upper frame member 11a, lower frame member 12, left frame member 11b, right frame member 11c) that are joined together, and is a frame that is incorporated into the opening 101 formed in the panel body 100. In the following explanation, the direction that corresponds to the thickness when incorporated into the panel body 100 will simply be referred to as the "thickness direction." Also, for convenience, the side of the frame body 1 to which the trim strip 13 is attached will be referred to as the "indoor side," and the opposite side as the "outdoor side." Note that "indoor side" and "outdoor side" are for convenience in this explanation and do not exclude the case where the side to which the trim strip 13 is attached is the outdoor side (and the panel body according to the present invention can be installed in locations where there is no distinction between indoors and outdoors (locations that do not separate indoors and outdoors)).

[0020] The basic structure of frame 1 is the same as the frame (opening frame) shown in Patent Documents 1 to 3, and is a frame (for example, with a visible width of 1.5 mm) configured such that when assembled as a panel, the design surface of the frame in a front view (Figure 1) becomes thinner. As shown in Figure 2, the frame 1 of this embodiment is a rectangular frame in which the upper frame member 11a, lower frame member 12, left frame member 11b, and right frame member 11c are joined to each other by fastening members, which are screws (tapping screws) TS. The upper frame member 11a and the lower frame member 12 have tapping holes (fastening member receiving parts and screw receiving parts) TH for screwing (fastening) the left frame member 11b and the right frame member 11c together, and the upper and lower frame members are screwed together from both sides by sandwiching them between the left and right frame members. Each frame member of this embodiment is made of an aluminum profile. The frame 1 is assembled by first joining the frame members together (as shown in Figure 2), and then incorporated into the panel body, into which the glass or other fitting members 200 are fitted. Furthermore, the various components of the panel bodies other than the frame 1, and the process of assembling them as a panel body using the frame 1 to which each frame member is joined, are based on concepts similar to those disclosed in Patent Documents 1 to 3, and therefore, their explanation here will be omitted or simplified.

[0021] Figure 4 is an end view of the lower frame member 12 (the cross-section has the same shape). The lower frame member 12 has the following basic configuration: Side portions 121a and 121b located at both ends in the thickness direction (left-right direction in Figure 4), Connecting parts 123 and 129 that extend in the thickness direction and connect the side parts 121a and 121b, A receiving groove 125 for receiving the fitting member 200, When incorporated into the opening 101 of the panel body 100, the inner surface portion 122 (122a, 122b) of the opening constitutes the inner surface (side surface in the thickness direction) of the opening 101, A stepped recess 124a formed between the trim 13 and the side portion 121a, and a stepped recess 124b formed at the joint between the side portion 121b and the inner surface portion 122b of the opening, which is recessed inward in the thickness direction, A tapping hole (fastening member receiving part and screw receiving part) TH formed in the connecting part 123, A V-shaped groove 127 is formed on the opposite side of the connecting portion 123 from the surface in which the tapping hole TH is formed, and serves as a marker indicating the center position of the tapping hole TH. A support member 126b that supports the backup material BM (see Figure 5), It is equipped with. The trim strip 13, which forms the inner surface portion 122a of the opening and the receiving groove 125 when attached to the lower frame member 12, is a member that is attached to the frame body 1 (lower frame member 12) when fitting in the glass or other fitting member 200. Since the trim strip 13 is of the same concept as that described in the frame body (opening frame body) shown in Patent Documents 1 to 3, its explanation here will be omitted or simplified.

[0022] The receiving groove 125 has an entrance portion 1251 into which the fitting member 200 is inserted, and as you move inward from the entrance portion 1251 (towards the back in the insertion direction of the fitting member 200), there is a space in which the thickness direction is larger than that of the entrance portion 1251. The receiving groove 125 is offset in the thickness direction; that is, the center position of the frame member 12 in the thickness direction and the center position of the receiving groove 125 in the thickness direction are different. In other words, the distance from one end in the thickness direction to the entrance portion 1251 (the length in the thickness direction of the inner surface portion 122a of the opening) and the distance from the other end in the thickness direction to the entrance portion 1251 (the length in the thickness direction of the inner surface portion 122b of the opening) are different. The reason the receiving groove 125 is offset from the center is that the trim strip 13 is standardized in the frame bodies corresponding to panel bodies of different thicknesses. As the thickness of the panel bodies differs, the thickness of the frame members also changes accordingly, but since the trim strip 13 is standardized (the thickness of the inner surface portion 122a of the opening is constant), the receiving groove 125 is offset from the center as a result.

[0023] The tapping holes TH in the lower frame member 12 are fastening holes into which the two lower tapping screws TS shown in Figure 2 are screwed, and as shown in Figure 4, they are formed at an offset position from the center CL in the thickness direction of the lower frame member 12. This configuration is designed to prevent incorrect mounting directions (and to allow for immediate detection of errors) when the mounting orientation of the frame member is determined by the offset of the receiving groove 125 from the center (the function based on this configuration will be explained later). In this embodiment, the tapping hole TH is offset to the side of the inner surface portion 122a of the opening. That is, "the screw receiving portion (tapping hole) is offset to the side where the distance from the end in the thickness direction of the frame member to the receiving groove is shorter."

[0024] The receiving member 126b that supports the backup material BM (see Figure 5) is located on the outdoor side of the entrance portion 1251, at the rear (downward in Figure 4) position, and is formed in a position that faces the fitting member 200 when the fitting member 200 is inserted. Furthermore, the support member 126b is not limited to being formed continuously in the longitudinal direction of the lower frame member 12, but may also be formed intermittently (as long as it can support the backup material BM).

[0025] Furthermore, the configuration of the tapping holes TH (the point that their formation position is offset from the center) and the basic configuration of the lower frame member 12, other than the receiving member 126b, are based on the same concepts as those described in the frame bodies (opening frame bodies) shown in Patent Documents 1 to 3, so no further explanation is provided here.

[0026] Figure 3 is an end view showing the frame member 11. In this embodiment, the upper frame member 11a, the left frame member 11b, and the right frame member 11c are made of a frame member 11 having the end face shape (and cross-sectional shape) shown in Figure 3. That is, the upper frame member 11a, the left frame member 11b, and the right frame member 11c are formed by cutting the common frame member 11 to the length corresponding to each member. The frame member 11 has the following basic configuration: Side portions 111a and 111b located at both ends in the thickness direction (left-right direction in Figure 3), A connecting portion 113 extends in the thickness direction and connects the side portions 111a and 111b, A receiving groove 115 for receiving the fitting member 200, When incorporated into the opening 101 of the panel body 100, the inner surface portion 112 (112a, 112b) of the opening constitutes the inner surface (side surface in the thickness direction) of the opening 101, Step recesses 114a, 114b are formed at the joint between the side portions 111a, 111b and the inner portions 112a, 112b of the opening, and are recessed inward in the thickness direction. A tapping hole (fastening member receiving part and screw receiving part) TH formed in the connecting part 113, A V-shaped groove 117 is formed on the opposite side of the connecting portion 113 from the surface in which the tapping hole TH is formed, and serves as a marker indicating the center position of the tapping hole TH. Support members 116a and 116b that support the backup material BM (see Figures 5 and 6), Reinforcement parts 118a, 118b, It is equipped with.

[0027] The receiving groove 115 has an entrance portion 1151 into which the fitting member 200 is inserted, and as you move inward from the entrance portion 1151 (towards the back in the insertion direction of the fitting member 200), there is a space in which the thickness direction is larger than that of the entrance portion 1151. The receiving groove 115 is offset in the thickness direction; that is, the central position of the frame member 11 in the thickness direction and the central position of the receiving groove 115 in the thickness direction are different. In other words, the distance from one end in the thickness direction to the entrance portion 1151 (the length in the thickness direction of the inner surface portion 112a of the opening) and the distance from the other end in the thickness direction to the entrance portion 1151 (the length in the thickness direction of the inner surface portion 112b of the opening) are different. The reason the receiving groove 115 is offset from the center is that the receiving groove 125 of the lower frame member 12 is offset for the reasons mentioned above, and the configuration is designed to match this (the groove positions are aligned).

[0028] The tapping holes TH are fastening holes into which the two upper tapping screws TS shown in Figure 2 are screwed when the frame member 11 is used as the upper frame member 11a. As shown in Figure 3, they are formed at an offset position from the center CL in the thickness direction of the frame member 11 (upper frame member 11a). This configuration, similar to the lower frame member 12, is designed to prevent errors in the mounting direction of frame members when the mounting direction is predetermined (and to allow for immediate detection of errors) (the function based on this configuration will be explained later). In this embodiment, the tapping hole TH is offset to the side of the inner surface portion 112a of the opening. That is, "the screw receiving portion (tapping hole) is offset to the side where the distance from the end in the thickness direction of the frame member to the receiving groove is shorter." In addition, if the frame member 11 is used as the left frame member 11b and the right frame member 11c, the tapping hole TH is not required; however, in this embodiment, the parts are standardized. The left frame member 11b and the right frame member 11c have through holes (not shown in particular) for inserting and locking tapping screws TS.

[0029] The support members 116a and 116b that support the backup material BM (see Figures 5 and 6) are formed at positions on both sides of the entrance portion 1151, towards the back (downward in Figure 3), and are positioned opposite the fitting member 200 when the fitting member 200 is inserted. The outdoor receiving member 116b is formed in a rib shape that protrudes downward from the inner surface portion 112b of the opening. The indoor receiving member 116a is formed by the inner surface of the stepped recess 114a. In other words, "the inner surface of the stepped recess on the side with the shorter distance from the end in the thickness direction to the receiving groove functions as the receiving member." Furthermore, the distance L1 from the end of the inlet portion 1151 to the receiving member 116a on the indoor side and the distance L2 from the end of the inlet portion 1151 to the receiving member 116b on the outdoor side are approximately the same (see Figure 3). In other words, "the distance from one end of the inlet portion in the thickness direction to the receiving member on one side and the distance from the other end of the inlet portion in the thickness direction to the receiving member on the other side" are approximately the same. Furthermore, the support member 116b is not limited to being continuously formed in the longitudinal direction of the frame member 11, but may also be formed intermittently (as long as it can support the backup material BM).

[0030] The reinforcing parts 118a and 118b are connected to the side parts 111a and 111b and the connecting part 113 in a tapered manner at the point where they intersect perpendicularly in a cross-sectional view, thereby increasing the cross-sectional area and increasing the section modulus of the frame member 11.

[0031] Furthermore, the basic structure of the frame member 11, other than the configuration of the tapping holes TH (the point that the formation position is offset from the center), the reinforcing parts 118a and 118b, and the receiving member 116b, is the same concept as that described in the frame bodies (opening frame bodies) shown in Patent Documents 1 to 3, so further explanation is omitted here.

[0032] Figure 5 is a cross-sectional view of the panel body 100 along line AA in Figure 2, and Figure 6 is a cross-sectional view of the panel body along line BB in Figure 2 (Note that Figure 2 shows only the frame body 1 without the trim 13 attached, while Figures 5 and 6 are cross-sectional views of the panel body as it is configured). In this embodiment, the panel body 100 is formed by assembling the panel body by incorporating the frame body 1 (frame body 1 in the state shown in Figure 2), then fitting the interlocking members 200 into the receiving grooves 115 and 125 by inserting them diagonally into the upper and lower frame members using a skewing method, and into the left and right frame members, before attaching the trim 13, temporarily fixing the interlocking members 200 by inserting the backup material BM into the gap between the receiving grooves 115 and 125 and the interlocking members 200, and finally fixing them with the sealing material SM. In this process, the formation of receiving members 116a, 116b, and 126b prevents the backup material BM, which is used to temporarily fix the fitting member 200, from falling into the spaces within the receiving grooves 115 and 125. Based on the fact that the receiving groove described above is offset from the center, the space is particularly wide on the outdoor side. In conventional frames, the backup material BM tends to fall into this outdoor space. However, according to this embodiment, the receiving members 116b and 126b prevent the backup material BM from falling into the outdoor side of the space. This significantly improves work efficiency and also reduces construction time. Furthermore, since L1 and L2 shown in Figure 3 are substantially the same, the fitting member 200 can be temporarily fixed (positioned) with backup material BM of the same size on both sides, making it easy to center the fitting member 200 (positioning it in the center in the depth direction within the receiving grooves 115 and 125), which can improve the finish of the product and also improve workability. Furthermore, a support member for the backup material BM may also be provided on the trim strip 13. That is, on the lower frame member 12, a support member may be provided at a position on the interior side of the entrance portion 1251, and at a position facing the fitting member 200 when the fitting member 200 is inserted. This ensures that the backup material BM is also supported on the interior side (trimming strip side) of the lower frame member.

[0033] Next, we will explain the function of the tapping holes TH, which are formed at an offset position from the center CL in the thickness direction of the frame member, in order to prevent errors in the mounting direction of the frame member (and to allow for immediate detection of errors). For the purposes of this explanation, other examples of frame members (frame members with different thicknesses corresponding to differences in panel thickness) are shown in Figures 7 and 8. The frame member 11-1 shown in Figure 7 and the lower frame member 12-1 shown in Figure 8 are frame members that correspond to panel bodies with a greater thickness than the frame member 11 and lower frame member 12 described above, and their basic configuration is the same as that of the frame member 11 and lower frame member 12 (the same reference numerals are used for identical components). As mentioned above, the trim strip 13 is a common part among members with these thickness variations, and as a result, the widths of the inner surfaces 112a and 122a of the openings are the same. As the thickness of the frame members increases, the widths of the inner surfaces 112a and 122a of the openings remain the same, and the width of the entrance portion of the receiving groove is also the same, so the widths of the inner surfaces 112b-1 and 122b-1 of the openings increase (the offset amount increases). Furthermore, in the frame member 11-1 in Figure 7 and the lower frame member 12-1 in Figure 8, the outdoor receiving members 116b-1 and 126b-1 are formed to connect the inner surfaces of the openings 112b-1 and 122b-1 with the connecting parts 113-1 and 123 (forming a bridging shape). This improves the rigidity and strength of the frame member, allowing the thickness of the connecting parts to be reduced compared to frame member 11, and also eliminating the need for reinforcing parts 118a and 118b. On the other hand, the outdoor receiving members 116b and 126b of frame member 11 and lower frame member 12 are formed in a rib shape that protrudes downward from the inner surface of the opening 112b (not forming a bridging shape). This is the minimum structure that functions as an opposing part (receiving member) capable of holding a portion of the backup material (rib-shaped part). In this way, at least the necessary rigidity and strength are ensured while reducing the amount of material used, thereby reducing material costs and weight load.

[0034] Figure 10 illustrates a conventional frame member connection in which a tapping hole is formed at the center of the frame member in the thickness direction. Figure 10(a) shows the correct orientation of the connection between frame members (left frame member 11b-P and upper frame member 11a-P) having the same thickness as the frame member 11 of this embodiment, while Figure 10(b) shows the incorrect orientation of the connection. Similarly, Figure 10(c) shows the correct orientation of a connection between frame members (left frame member 11-1b-P and upper frame member 11-1a-P) having the same thickness as the frame member 11-1 described above, while Figure 10(d) shows an incorrect orientation of the connection. As shown in Figures 10(a) and (c), when connected in the correct orientation, the receiving groove is correctly formed (the width W for inserting the fitting member is correctly formed). On the other hand, in the cases of Figures 10(b) and (d), the width W of the receiving groove is too small, making it impossible to correctly position the fitting member 200. When the tapping hole is formed at the center in the thickness direction of the frame member, as shown in Figures 10(b) and (d), even if the mounting direction of the frame member is incorrect, there is little difference in appearance (each frame member is connected flush), and it is easy to overlook the difference in mounting direction. If the incorrect mounting direction is not noticed and the assembly is then put into the panel body, a defective product will be manufactured.

[0035] Figure 9 illustrates the connection of the frame members in this embodiment. Figure 9(a) shows the correct orientation of the connection between the frame members 11 (left frame member 11b and upper frame member 11a) in this embodiment, while Figure 9(b) shows the incorrect orientation of the connection. Similarly, Figure 9(c) shows the correct orientation of the connection between the frame members 11-1 (left frame member 11-1b and upper frame member 11-1a) as described above, while Figure 9(d) shows the incorrect orientation of the connection. As can be seen from Figures 9(b) and (d), the tapping holes TH are formed at an offset position from the center CL in the thickness direction of the frame members. Therefore, if the frame members are connected in the wrong direction, a step (misalignment) will occur in the connection between the frame members. Thus, it is clear that the mounting direction is incorrect. In fact, when attempting to assemble the parts, the difference in direction (misalignment between parts) can be noticed at the stage of aligning the screw holes, thus preventing assembly in the wrong direction.

[0036] Based on the above, in the method for manufacturing the panel body of this embodiment, The steps include: forming a frame by joining multiple frame members together by screwing them into tapping holes (screw receiving parts); The steps include checking whether the multiple joined frame members are misaligned in the thickness direction (i.e., whether there are any steps or discrepancies), The steps include forming a panel body incorporating a frame without misalignment, Steps include attaching the fitting member to the frame, By doing so, the production of defective products is reduced. Furthermore, "checking whether the multiple joined frame members are misaligned relative to each other in the thickness direction" can be judged at a glance, as can be understood from the above, and does not require much effort to check, making it unlikely to be overlooked (as mentioned above, the fact that they are assembled in the wrong direction in the first place is prevented). Furthermore, even if an oversight occurs, a frame with misaligned connections between frame members cannot be incorporated into a panel, thus effectively preventing the manufacture of defective panel units.

[0037] As described above, the panel body 100 (frame body 1) and its manufacturing method according to this embodiment make it possible to reduce the chances of incorrectly attaching the frame members (making it easier to notice the mistake), and effectively prevent the manufacture of defective panel bodies. Furthermore, in the panel body 100 (frame body 1) of this embodiment, the receiving members 116a, 116b, and 126b are formed, which prevents the backup material BM for temporarily fixing the fitting member 200 from falling into the space within the receiving grooves 115 and 125. As a result, workability is greatly improved and construction time is reduced.

[0038] Furthermore, according to this embodiment, the tapping hole TH is offset toward the side of the trim 13 (indoor side), that is, "the screw receiving portion (tapping hole) is offset toward the side where the distance from the end in the thickness direction of the frame member to the receiving groove is shorter," which provides the advantage of easily forming through holes for inserting the tapping screws TS in the left frame member and the right frame member. If the tapping hole TH is provided on the exterior side, it is necessary to form an insertion hole for the tapping screw TS on the exterior side as well. However, a receiving member is formed on the exterior side (particularly 116b-1 in Figure 7 and 126b-1 in Figure 8), and a greater machining force is required to form an insertion hole there. Furthermore, applying a large machining force may cause deformation or damage to the member. According to this embodiment, such problems are reduced.

[0039] In the embodiment, a frame is shown as an example in which the design surface (visible side) of the frame becomes thinner when assembled as a panel body. However, the present invention is not limited to this, and a frame with a thicker visible side may also be used. Furthermore, although the embodiment uses a rectangular frame constructed with four frame members as an example, the present invention is not limited to this (for example, a frame of any polygonal shape or circular shape may also be used).

[0040] The function of forming tapping holes (screw receiving parts) at a position offset from the center in the thickness direction of the frame member, thereby preventing errors in the mounting direction of the frame member, is useful when there are restrictions on the mounting direction of the frame member. However, even when there are no restrictions on the mounting direction of the frame member, the screw receiving parts (fastening member receiving parts) may be formed at an offset position. Furthermore, "forming the fastening member receiving portion at a position offset from the center in the thickness direction of the frame member" indicates that the position of the center of the fastening member receiving portion in the thickness direction and the center in the thickness direction of the frame member are not the same. Here, "center of the fastening member receiving portion" refers to the center of the fastening member (one screw) when one fastening member is arranged as in this embodiment, and to the centers of the fastening members when multiple fastening members are arranged (for example, the midpoint between two screws when two screws are arranged).

[0041] In this embodiment, the upper frame member and the lower frame member are shown as being screwed together from both sides by the left and right frame members, but the present invention is not limited to this, and any arrangement in which the frame members can be joined together is acceptable (for example, the left and right frame members are sandwiched between the upper and lower frame members, or any other arrangement in which the frame members can be joined, and the concept of the present invention can be applied to these). Furthermore, in this embodiment, the upper frame member 11a, left frame member 11b, and right frame member 11c are shown as being formed based on a common frame member 11. However, the present invention is not limited to this, and each member may be formed independently. For example, the left and right frame members may be frame members without tapping holes (screw receiving parts) (frame members with a different configuration from the upper frame member) (whether tapping holes (screw receiving parts) are required for each member will depend on the arrangement of the joints of each frame member).
