Description

[Technical Field]

[0001] The present invention relates to a cosmetic cover. [Background technology]

[0002] Conventionally, there are many known wall structures such as continuous window sashes and curtain walls in which adjacent panel sections are connected by mullions. For example, Patent Document 1 below proposes a wall structure that has fire resistance and includes mullions and panel units attached to the mullions. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-139308 Summary of the Invention [Problem to be solved by the invention]

[0004] However, because the mullions of wall structures are typically made of extruded aluminum, the amount of heat lost from the mullions is large. As a result, when the outside temperature is low, the surface temperature of the indoor side of the mullions drops, creating the problem of condensation. This is particularly noticeable when the indoor humidity is increased for virus prevention measures, etc. Another problem is that because the mullions are made of extruded aluminum, there are often restrictions on the design of the mullion surface, making it difficult to improve the appearance quality.

[0005] The present invention has been made in consideration of the above circumstances, and its objective is to provide a decorative cover that can reduce the amount of heat that flows out of the support and improve the appearance quality. [Means for solving the problem]

[0006] In order to solve the above problems, the decorative cover of the present invention is a decorative cover that covers a post that connects multiple adjacent panel sections, and is characterized in that it comprises a wooden cover body that covers the protruding sections that protrude outward from the multiple panel sections, and an attachment section for attaching the cover body to the post, and the cover body has a front section covering section that covers the front section of the post, and a front section covering section that covers the front sections on both sides of the front section.

[0007] According to the present invention, the cover body that covers the protruding portion is made of wood and includes a facing covering portion that covers the facing portion of the mullion and facing covering portions on both sides of the facing portion. This allows a wide area of ​​the protruding portion of the mullion that protrudes outward from the adjacent panel portions to be covered with wood that has excellent insulating properties. This reduces the amount of heat loss from the mullion, even if the mullion is made of a material with good thermal conductivity, such as metal. In addition, since the protruding portions that protrude outward from the adjacent panel portions are covered by the cover body, the outer surface of the cover body is visible from the outside instead of the protruding portions of the mullion, so the design of the cover body can improve the appearance quality of the mullion. Therefore, the decorative cover of the present invention can reduce the amount of heat that flows out of the mullion and also improve the appearance quality.

[0008] In the present invention, the cover body may be provided with a recess in which the protruding portion covering portion and the protruding portion covering portion are provided and which can accommodate the protrusion.

[0009] In this way, the facing and recessed portions of the mullion can be covered by the cover body simply by accommodating the protruding portion of the mullion in the recess. Also, since the decorative cover can be attached by fitting the recess of the decorative cover into the protruding portion of the mullion, the decorative cover can be easily attached to the mullion.

[0010] In the present invention, the mounting portion may include an engaging portion provided downward on the inner surface of the recess and an engaged portion provided upward on the protrusion, and the engaging portion may be able to engage with the engaged portion by placing the recess over the protrusion and moving the cover body downward.

[0011] In this way, the cover body can be attached to the protruding part of the upright by simply placing the recess over the protruding part of the upright and moving the cover body downward. This makes the decorative cover installation easy, and the cover body can be easily attached to uprights installed in existing buildings.

[0012] In the present invention, the locking portion and the locked portion may be made of a common bent plate member, and may have a fixing piece that can be fixed to either the inner surface of the recess or the visible portion, and a protruding piece that protrudes from the fixing piece so as to be away from the inner surface or the visible portion and can be used for either the locking portion or the locked portion.

[0013] In this way, the bent plate member can be used in common for both the locking portion and the locked portion, so the mounting portion can be constructed simply, making the work of mounting the decorative cover even easier.

[0014] In the present invention, the cover body may be configured to be arranged in multiple rows one above the other so as to continuously cover the protrusion, and may have an outer surface in which the amount of protrusion from the upright protrusion increases from the upper end side to the lower end side.

[0015] In this way, each decorative cover that covers the protruding portion of the mullion can be made significantly shorter than the mullion, making it easier to handle before attaching it to the mullion. Also, even when multiple decorative covers are arranged side by side, when rain or dew droplets adhere to the outer surface and flow down, the flowing water is less likely to adhere to the upper end of the lower cover body, preventing water from seeping inside the lower cover body and improving the durability of the cover body.

[0016] In the present invention, the panel portion may have a window panel that separates the inside of the room from the outside, and the cover main body may cover the protrusion that protrudes to the outside of the room.

[0017] In this way, it is possible to easily form a continuous window that can reduce the amount of heat loss in the mullions and improve the appearance quality. [Effects of the Invention]

[0018] According to the decorative cover of the present invention, the amount of heat that flows out of the mullion can be reduced, and the appearance quality can be improved. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is a perspective view showing the state in which the decorative cover is attached to the upright, Fig. 2 is a side view showing the state in which the decorative cover is attached to the upright, Fig. 3 is a cross-sectional view showing the state in which the decorative cover is attached to the upright, which corresponds to the cross section AA in Fig. 2. Fig. 4 is a longitudinal cross-sectional view showing the state in which the decorative cover is attached to the upright, (a) showing the upper end side and (b) showing the lower end side.

[0021] The decorative cover 10 of this embodiment is a cover that covers the mullions 12 that connect the adjacent panel portions 11 together.

[0022] The mullions 12 connect the window panels of the continuous sash that separates the interior 18 from the exterior 19, and are made of extruded aluminum profiles. The upper and lower ends of the mullions 12 are fixed to the upper frame 13 and lower frame 14, and the mullions are installed vertically. Support portions 15 for supporting the panel portions 11 are provided on both the left and right sides of the mullions 12, and protrusions 16 are provided on the exterior 19 side so as to protrude further than the panel portions 11 on both sides. The support portions 15 and protrusions 16 are provided continuously over almost the entire length of the mullions 12.

[0023] The decorative cover 10 is arranged to cover the protruding portion 16 that protrudes toward the outside 19 side of the mullion 12. The decorative cover 10 comprises a wooden cover body 17 and an attachment portion 21 for attaching the cover body 17 to the mullion 12.

[0024] FIG. 5 shows the cover body 17, where (a) is a side view and (b) is a cross-sectional view taken along the line BB in (a).

[0025] The cover body 17 covers almost the entire protruding portion 16 of the mullion 12 that protrudes outward from the multiple panel portions 11. This cover body 17 has a facing portion covering portion 23 that covers the facing portion 22 of the mullion, and facing portion covering portions 25 that cover the facing portions 24 on both sides of the facing portion 22. In this embodiment, the facing portion 22 on the outdoor 19 side of the mullion 12 is made of a flat surface, so the facing portion covering portion 23 is arranged facing and approximately parallel to the flat surface of the facing portion 22.

[0026] 5, the cover body 17 of this embodiment has the facing portion covering portion 23 and the facing portion covering portion 25 integrated together, and has a recess 26 formed therein that can accommodate the protrusion 16. The width of the recess 26 corresponds to the width of the facing portion 22 of the protrusion 16 of the mullion 12, and is formed to a width that can accommodate the protrusion 16. The depth of the recess 26 in the indoor / outdoor direction corresponds to the protrusion dimension of the facing portion 24 from the surface of the multiple panel portions 11 to the facing portion 22 of the protrusion 16 of the mullion 12.

[0027] As shown in Figures 1 and 2, a plurality of cover bodies 17 are arranged vertically to continuously cover substantially the entire length of the protruding portion 16 of the upright 12. The plurality of cover bodies 17 may be formed to have lengths that divide the entire length of the upright 12 into several substantially equal parts. Both side surfaces of the cover body 17 are formed parallel to each other. The width of the cover body 17 is formed to be substantially constant along the entire length, but the outer surface 41 on the front side is inclined so that the amount of protrusion from the protruding portion 16 of the upright 12 increases from the upper end to the lower end.

[0028] 2 and 5(a), a notch 27 is formed in the lower end of each cover body 17 to accommodate the upper end of another cover body 17 arranged adjacently below. The notch 27 of the cover body 17 is formed on the side of the mullion 12. When the cover bodies 17 are arranged adjacently above and below, the upper end 42 of the other lower cover body 17 is accommodated in the notch 27 of the upper cover body 17.

[0029] Figure 6 shows a curved plate member as an engaging part attached to the cover body, (a) being an oblique view and (b) being a side view, and Figure 7 shows a curved plate member as an engaged part attached to the protruding part of the upright, (a) being an oblique view and (b) being a side view.

[0030] The mounting portion 21 includes a locking portion 31 provided on the inner surface of the recess 26 facing downward, and a locked portion 32 provided on the protruding portion 16 facing upward.

[0031] 6(a) and 6(b), the locking portion 31 has a fixing piece 33 that can be fixed to the inner surface 43 of the recess 26, and a protruding piece 34 that protrudes from the fixing piece 33 and is spaced apart from the inner surface 43. A connecting piece is provided to connect the fixing piece 33 and the protruding piece 34, and the bent plate member 35 is formed in a crank shape in side view.

[0032] On the other hand, as shown in Figures 7(a) and (b), the engaging portion 32 has a fixed piece 33 that can be fixed to the visible portion 22, and a protruding piece 34 that protrudes from the fixed piece 33 so as to be spaced away from the visible portion 22 and is used as the engaging portion 32.

[0033] In this embodiment, the locking portion 31 and the locked portion 32 are formed from a common bent plate member 35. A flat fixing piece 33 and a flat protruding piece 34 are provided in a stepped shape via a bent portion on the bent plate member 35. By fixing the fixing piece 33 to the inner surface 43 of the recess 26 or the visible portion 22, a gap is formed between the fixing piece 33 and the protruding piece 34, and the fixing piece 33 is used as the locking portion 31 or the locked portion 32.

[0034] Such a decorative cover 10 can be attached to the mullions 12 as follows: In this case, the decorative cover 10 is attached to the mullions 12 after they have already been installed with the adjacent panel sections 11 connected together.

[0035] First, as shown in Figures 6(a) and 6(b), the bent plate member 35 is fixed in advance as the locking portion 31 to the inner surface 43 of the recess 26 of the cover body 17. At this time, the bent plate member 35 is fixed upside down to the decorative cover 10 placed at the top of the upright 12 (see Figures 2 and 4(a)).

[0036] 7(a) and (b), a bent plate member 35 is fixed in advance as an engaging portion 32 at a predetermined position on the facing portion 22 of the upright 12. The predetermined position corresponds to the position where the engaging portion 31 of each decorative cover 10 is disposed on the facing portion 22 of the upright 12. At this time, the bent plate member 35 disposed at the top position of the upright 12 is left unfixed.

[0037] 2 and 4(b), the decorative cover 10 at the lowest position of the upright 12 is attached to the upright 12. At this time, the recess 26 of the cover body 17 is placed over the protrusion 16, and then the cover body 17 is moved downward to engage the locking portion 31 with the locked portion 32.

[0038] Next, the decorative cover 10 placed adjacently directly above is attached. In the same manner as the decorative cover 10 in the lowest position, the locking portion 31 on the cover body 17 of the decorative cover 10 placed above is locked with the locked portion 32. At this time, the cutout portion 27 of the upper cover body 17 is positioned to accommodate the upper end portion 42 of the lower cover body 17. Thereafter, the same process is repeated until the decorative cover 10 in the highest position is attached.

[0039] 2 and 4(a), to attach the decorative cover 10 in the uppermost position, the recess 26 of the cover body 17 of the decorative cover 10 in the uppermost position is placed over the protrusion 16, and the cover body 17 is moved downward so that the locking portion 31 on the lower side of the decorative cover 10 is locked with the locked portion 32. As a result, the locking portion 31 on the lower end side of the decorative cover 10 in the uppermost position is locked with the locked portion 32 of the protrusion 16.

[0040] Next, the protruding piece 34 of the bent plate member 35 placed at the top of the upright 12 is engaged upside down with the engaging portion 31 attached upside down to the upper end of the decorative cover 10 at the top position. In this state, the fixing piece 33 of the bent plate member 35 is positioned so as to protrude upward from the cover body 17. The decorative cover 10 at the top position is attached to the upright 12 by fixing this fixing piece 33 at the top position of the upright 12 with a screw or the like. In this way, by attaching multiple decorative covers 10 in a row and attached to the protruding portion 16 of the upright 12, the decorative cover 10 continuously covers almost the entire length of the upright 12.

[0041] As shown in FIG. 1, sawtooth grooves 45 are formed in the vertical direction on the outer surface 41 of the cover body 17 of this embodiment. The grooves 45 are formed over the entire length of the cover body 17. The grooves 45 serve as flow paths for rainwater and the like. The grooves 45 also serve a design purpose, so the size and shape of the grooves may be changed as appropriate. The grooves 45 do not necessarily have to be formed.

[0042] Next, the effects of the decorative cover 10 of this embodiment will be described. According to the decorative cover 10 of this embodiment, the cover body 17 covering the protruding portion 16 is made of wood and includes a protruding portion covering portion 23 that covers the protruding portion 22 of the mullion 12 and a protruding portion covering portion 25 that covers the protruding portions 24 on both sides of the protruding portion 22. Therefore, a wide area, i.e., substantially the entire exposed portion of the protruding portion 16 of the mullion 12 that protrudes outward from the panel portion 11, can be covered with wood, which has excellent insulating properties. This reduces the amount of heat loss from the mullion 12 to the outside, even if the mullion 12 is made of a material with good thermal conductivity, such as aluminum or other metal. At the same time, because the protruding portion 16 that protrudes outward from the panel portion 11 is substantially entirely covered by the cover body 17, the outer surface 41 of the cover body 17 is visible from the outside instead of the protruding portion 16 of the mullion 12. Therefore, the design of the cover body 17 improves the appearance quality of the mullion 12.

[0043] In addition, in this embodiment, the cover body 17 is provided with a recess 26 that has the facing portion covering portion 23 and the facing portion covering portion 25 and can accommodate the protrusion 16. Therefore, simply by accommodating the protrusion 16 of the mullion 12 in the recess 26, the facing portion 22 and the facing portion 24 of the mullion 12 can be covered by the cover body 17. This makes it easy to attach the decorative cover 10 to the mullion 12.

[0044] Furthermore, in this embodiment, the mounting portion 21 has a locking portion 31 provided downward on the inner surface of the recess 26 and a locked portion 32 provided upward on the protrusion 16, and by placing the recess 26 over the protrusion 16 and moving the cover body 17 downward, the locking portion 31 can be locked with the locked portion 32. Therefore, simply by placing the recess 26 over the protrusion 16 of the upright 12 and moving the cover body 17 downward, the cover body can be attached to the protrusion 16 of the upright 12, making the installation of the decorative cover 10 easy. For example, the cover body can be easily attached even to a upright 12 that has already been installed.

[0045] Furthermore, in this embodiment, the locking portion 31 and the locked portion 32 are formed from a common bent plate member 35, and this bent plate member 35 has a fixing piece 33 that can be fixed to either the inner surface of the recess 26 or the visible portion 22, and a protruding piece 34 that protrudes from the fixing piece 33 so as to be away from the inner surface or the visible portion 22 and can be used for either the locking portion 31 or the locked portion 32. Therefore, since the bent plate member 35 can be used in common for both the locking portion 31 and the locked portion 32, the mounting portion 21 can be configured even more simply, and the installation work of the decorative cover 10 can be made even easier.

[0046] In addition, in this embodiment, multiple decorative covers 10 are arranged vertically, allowing for continuous coverage of the protrusions 16. This allows each decorative cover 10 to be significantly shorter and more compact than the uprights 12, making it easier to handle before attaching it to the uprights 12 and improving workability and portability. Furthermore, each cover body 17 has an outer surface in which the amount of protrusion from the protrusions 16 of the uprights 12 increases from the upper end to the lower end. Therefore, when water droplets, such as rain or dew, adhere to the outer surface and flow down, the flowing water is less likely to adhere to the upper end of the lower cover body 17. This prevents water from seeping inside the lower cover body 17, making it easier to prevent deterioration of the cover body 17.

[0047] Furthermore, in this embodiment, the panel portion 11 is a window panel that separates the room 18 from the outside 19, and the cover body 17 covers the protruding portion 16 that protrudes toward the outside 19. Therefore, it is possible to easily form a continuous window that can reduce the amount of heat loss from the room 18 to the outside 19 in the mullions 12 and improve the appearance quality.

[0048] In the above embodiment, an example of a transparent window panel that separates the interior 18 and exterior 19 of the room was described as the panel portion 11, but this is not particularly limited, and the present invention can be similarly applied even if the panel portion is a partition panel, such as a curtain wall.

[0049] In addition, in the above-described cover body 17, an example has been described in which the recess 26 is provided by integrating the front-portion covering portion 23 and the front-portion covering portion 25, but the two may be provided separately. In that case, the recess 26 does not need to be provided.

[0050] Furthermore, in the above embodiment, the locking portion 31 and the locked portion 32 are configured to be able to be locked by moving the cover body 17 downward, but this is not particularly limited. Other attachment means can be used as long as the decorative cover 10 can be stably attached to the upright 12.

[0051] In the above embodiment, the locking portion 31 and the locked portion 32 are made of the common bent plate member 35, but they may be made of different members. Furthermore, the locking portion 31 may be a portion formed integrally with the cover body 17, and the locked portion 32 may be a portion formed integrally with the upright.

[0052] Furthermore, in the above embodiment, all of the cover bodies 17 have outer surfaces that protrude more from the upper end to the lower end and are provided with cutout portions 27, but the shape of the cover bodies 17 is arbitrary and can be various shapes. [Explanation of symbols]
