Description

Technical Field

[0001] The present invention relates to a surface mounting frame for clamping an end portion of a surface mounting sheet material covering a subfloor, and a method of using the surface mounting frame.

Background Art

[0002] Conventionally, a method of using a wall mounting member has been known (Patent Document 1). This method of using a wall mounting member includes a substrate portion attached to a wall surface of a building and a pair of standing plate portions formed to rise from the substrate portion. The tip portions of the standing plate portions are bent in a substantially U-turn shape and elastically pressed against each other to come into contact. Wave-shaped uneven surfaces are formed on the cross-sections of the tip portions of the pair of standing plate portions, and the concave and convex portions of the pair of uneven surfaces are engaged with each other to come into contact. Cuts extending to the substrate portion are alternately made in the pair of standing plate portions at intervals in the longitudinal direction thereof, so that the wall mounting member is formed to be foldable along the wall surface. The wall mounting member is folded along the wall surface and attached to the wall surface. A functional material having the same thickness as the height of the wall mounting member is fixed on the inner and / or outer wall surfaces of the folded wall mounting member. The peripheral portion of a wall cover sheet material is sandwiched and locked between a pair of wave-shaped uneven surfaces of the tip portions of the wall mounting member that are pressed against each other to come into contact.

Problems to be Solved by the Invention

[0004] However, the method of using the wall mounting member described in Patent Document 1 has a problem in that when installing it on a wall surface of a building, if the wall cover sheet material is sandwiched between the tips of the wall mounting member and the position adjustment of the wall cover sheet material (such as adjusting the curvature of the fabric if the wall cover sheet material is made of cloth, etc.) is performed, the force that clamps and locks the wall cover sheet material is too strong, making it difficult to adjust its position. Furthermore, the method of using the wall mounting member described in Patent Document 1 did not provide sufficient force to clamp and secure the wall cover sheet material, depending on its thickness (for example, if it was thin).

[0005] In view of these points, the present invention aims to provide a mounting frame and a method for using the mounting frame that can achieve "facilitation of position adjustment of the mounting sheet" and "improvement of the clamping force of the mounting sheet" by setting the resistance load when sliding the clamped mounting sheet material in the longitudinal direction of the frame to 60 N / 100 mm or less, and the resistance load when sliding the frame in a substantially perpendicular direction to the frame to 43 N / 100 mm or more. [Means for solving the problem]

[0006] The first feature of the present invention is that the covering frame 1 is a covering frame that clamps the end of a covering sheet material that covers a base surface, and the covering frame is a frame material having a longitudinal direction, and when the end of the covering sheet material with a thickness of 1.20 mm is clamped, the resistance load when the covering sheet material is slid along the longitudinal direction is 60 N / 100 mm or less, and when the end of the covering sheet material with a thickness of 0.15 mm is clamped, the resistance load when the covering sheet material is slid along a direction substantially perpendicular to the longitudinal direction is 43 N / 100 mm or more.

[0007] A second feature of the covering frame 1 according to the present invention is that, in addition to the first feature described above, it has a base plate that abuts against and is fixed to the base surface, a support plate rising from the base plate, a plurality of tongue pieces protruding from the side surface of the support plate, and an edge plate that rises from the base plate and can hold the end of the covering sheet material between itself and the tip of the tongue pieces.

[0008] A third feature of the covering frame 1 according to the present invention is, in addition to the first feature described above, that it has a base plate that abuts against and is fixed to the base surface, one support plate rising from the base plate, a plurality of one tongue pieces protruding from the side surface of the one support plate, another support plate rising from the base plate, and a plurality of other tongue pieces protruding from the side surface of the other support plate and capable of gripping the end of the covering sheet material between itself and the tip of the one tongue piece.

[0009] A fourth feature of the covering frame 1 according to the present invention is, in addition to the second or third feature described above, that the Shore hardness of the tongue piece as measured by a JIS-Z-2246:2000 Type D testing machine is between 50 HS and 80 HS, and the Shore hardness of the support plate as defined in JIS-Z-2246:2000 is greater than 80 HS and 150 HS or less, or that the Shore hardness of the one tongue piece and the other tongue piece as measured by a JIS-Z-2246:2000 Type D testing machine is between 50 HS and 80 HS, and the Shore hardness of the one support plate and the other support plate as measured by a JIS-Z-2246:2000 Type D testing machine is greater than 80 HS and 150 HS or less.

[0010] These features make it easier to adjust the position of the covering sheet material H (such as adjusting the weave if the covering sheet material H is made of fabric) when installing the covering sheet material H on a substrate S such as a wall surface in a building, while the end of the covering sheet material H is clamped in place and the covering sheet material H is slid along the longitudinal direction L of the covering frame 1 to 60 N / 100 mm or less, and when sliding the covering sheet material H on a substrate S such as a wall surface in a building, while the end of the covering sheet material H is clamped in place and the covering sheet material H is slid along the longitudinal direction R of the covering frame 1 to 43 N / 100 mm or more. This makes it easier to adjust the position of the covering sheet material H (such as adjusting the weave if the covering sheet material H is made of fabric) when installing the covering sheet material H on a substrate S such as a wall surface in a building, while the end of the covering sheet material H is clamped in place and the covering sheet material H is slid At the same time, unlike Patent Document 1, the surface sheet material H can be gripped with sufficient clamping force regardless of its thickness (even when it is thin) ("Improved clamping force of surface sheet material"). Furthermore, fabric alignment adjustment refers to adjusting the orientation of the pattern, or the warp and weft directions of the fabric, when the covering sheet material H is a woven or knitted fabric.

[0011] In addition, the presence of a substrate 2, a support plate 3, multiple tongue pieces 4, and an edge plate 5 also facilitates "adjustment of the position of the covering sheet material" and "improves the clamping force of the covering sheet material." Furthermore, by having a substrate 2, one support plate 3A, multiple one tongue pieces 4A, another support plate 3B, and multiple other tongue pieces 4B, it is possible to "facilitate position adjustment of the covering sheet material" and "improve the clamping force of the covering sheet material."

[0012] Furthermore, by setting the Shore hardness of tongue piece 4, one tongue piece 4A, and the other tongue piece 4B to 50HS or more and 80HS or less, and the Shore hardness of support plate 3, one support plate 3A, and the other support plate 3B to be greater than 80HS and 150HS or less, it is possible to "facilitate position adjustment of the covering sheet material" and "improve the clamping force of the covering sheet material".

[0015] A third feature of the method of using the covering frame 1 according to the present invention is that, in addition to the first feature described above, the covering frame has a base plate that abuts against and is fixed to the base surface, a one support plate rising from the base plate, a plurality of one tongues protruding from the side surface of the one support plate, a other support plate rising from the base plate, and a plurality of other tongues protruding from the side surface of the other support plate and capable of clamping the end of the covering sheet material between itself and the tip of the one tongue, wherein the plurality of one tongues include a one tongue on the covering side and a one tongue on the back side, and the plurality of other tongues include a other tongue on the covering side and a other tongue on the back side, and the method of using the covering frame 1 according to the present invention has a temporary fixing step of clamping the end of the covering sheet material between the one tongue on the covering side and the other tongue on the covering side, and after the temporary fixing step, the method of clamping the end of the covering sheet material between the one tongue on the covering side and the one tongue on the back side and the other tongue on the covering side and the other tongue on the back side.

Modes for Carrying Out the Invention

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. <Mounting Frame Body 1> In FIGS. 1 to 7, a mounting frame body 1 according to the present invention is shown.

[0023] This covering frame 1 is a frame material that holds the end of the covering sheet material H, which will be described later, covering the base surface S, which will be described later, and has a longitudinal direction L (that is, the covering frame 1 is formed in a long shape). The longitudinal direction L of the covering frame 1 may be approximately straight or curved, and the base surface S may also be approximately flat or curved. The covering frame 1 can be configured in any way as long as the covering sheet material H described above can be stretched between multiple covering frame 1s. For example, each covering frame 1 may be fixed to the base surface S at a predetermined distance so that the covering sheet material H can be stretched between at least two covering frame 1s (see Figures 4 and 5).

[0024] As shown in Figure 1, the covering frame 1 according to the first embodiment of the present invention may have a configuration that includes a substrate 2, a support plate 3, a tongue piece 4, and an edge plate 5. The cover frame 1 of the first embodiment may be a modified example shown in Figure 2. As shown in Figure 3, the mounting frame 1 according to the second embodiment of the present invention may also have a configuration comprising a substrate 2, one support plate 3A, one tongue piece 4A, the other support plate 3B, and the other tongue piece 4B, and the mounting frame 1 may have a configuration other than those shown in Figures 1 to 3. The following describes each component.

[0025] <Board 2> As shown in Figures 1 to 5, the substrate 2 is a member that abuts against and is fixed to the aforementioned base surface S, and is a plate-shaped member having a longitudinal direction (the same direction as the longitudinal direction L of the covering frame 1). It can be said that this substrate 2 has the same configuration in the first embodiment, its modified form, and the second embodiment. On the substrate 2, one or more minute protrusions 2a may be formed on the surface side (exposed side) of the portion where the support plate 3, etc., described later, is not raised, and these minute protrusions 2a may be formed continuously along the longitudinal direction of the substrate 2.

[0026] The formation of these minute protrusions 2a helps to absorb the impact of fixing (such as stapling) when the covering frame 1 is fixed to the base surface S with fixing members T such as staples (approximately U-shaped nails) (see Figures 1 and 3), thereby reducing cracking of the substrate 2 and the covering frame 1. There are no particular restrictions on the material of substrate 2, but for example, it may be made of a hard material. In this invention, "hard" refers to a material whose Shore hardness, as defined in JIS-Z-2246:2000, is greater than 80HS and 150HS or less.

[0027] <Support plate 3, one side support plate 3A, other side support plate 3B> As shown in Figures 1 to 5, the support plate 3, etc., is a member that rises from the substrate 2 in a cross-sectional view, and is a plate-shaped member having a longitudinal direction (the same direction as the longitudinal direction L of the covering frame 1). The support plate 3, etc., may rise from the surface facing the substrate 2 at the middle of its width. Furthermore, the one support plate 3A and the other support plate 3B are components present in a single covering frame 1.

[0028] As shown in Figure 1, the support plate 3 of the first embodiment may be bent in a crank shape midway up in the rising direction (also called the direction from the surface side to the back side, the vertical direction, or the thickness direction of the surface sheet material H) after rising from the substrate 2, and may extend further in the rising direction for a predetermined distance from this crank portion. Furthermore, the support plate 3 of the first embodiment may have a canopy portion formed on the side opposite to the direction of protrusion of the tongue piece 4 etc., which will be described later, protruding from the side of this extended portion, and protruding in the opposite direction. As shown in Figure 2, the modified support plate 3 of the first embodiment does not necessarily have the crank portion, extension portion, or overhang portion described above. Instead, after rising from the substrate 2, it may be bent in a roughly L-shape midway in the rising direction, and the tongue piece 4 described later may protrude from the tip side (side in the rising direction) of the roughly L-shaped portion. Furthermore, the modified support plate 3 of the first embodiment may be formed with a lower rising height than the support plate 3 of the first embodiment.

[0029] As shown in Figure 3, the one support plate 3A and the other support plate 3B may rise from the surface facing the substrate 2 at a predetermined distance from the surface facing the substrate approximately in the center in the width direction, and each of the one support plate 3A and the other support plate 3B may have the crank portion, extension portion, and overhang portion described in the support plate 3 of the first embodiment formed thereon. Furthermore, the rise height of the support plate 3 in the first embodiment and the rise height of the one support plate 3A and the other support plate 3B in the second embodiment (the rise height of the covering frame 1) is not particularly limited, but may be, for example, 10 mm or more and 20 mm or less (14 mm, etc.), and the rise height of the support plate 3 in the modified example of the first embodiment is also not particularly limited, but may be, for example, 4 mm or more and 9 mm or less (7 mm, etc.). There are no particular restrictions on the material of support plate 3, etc., but for example, it may be made of a hard material.

[0030] <Tongue piece 4, one tongue piece 4A, the other tongue piece 4B> As shown in Figures 1 to 5, the tongue pieces 4, etc., are members that protrude in cross-sectional view from the side surface of the support plate 3, etc., as described above, and are plate-shaped members having a longitudinal direction (the same direction as the longitudinal direction L of the covering frame 1). The tongue piece 4 may protrude from the side of the tip of the support plate 3, or from the side of the middle or base of the support plate 3 in the rising direction. The angle of protrusion may be slightly downward (towards the substrate 2) or slightly upward (towards the opposite side of the substrate 2). For example, it may be between -5° and 20° (more than 5° upward and less than 20° downward). Furthermore, one tongue piece 4A and the other tongue piece 4B are components present in a single covering frame 1.

[0031] As shown in Figure 1, there may be multiple tongue pieces 4, for example, a tongue piece 4a on the facing side (the tip side in the rising direction) and a tongue piece 4b on the back side (the base end side in the rising direction). The tongue piece 4b on the back side protrudes from the side of the crank portion (midway up the rising direction) of the support plate 3 described above, and the tongue piece 4a on the front side protrudes from the side of the tip of the extended portion of the support plate 3 described above. In the first embodiment, the tongues 4a on the fronting side and 4b on the back side may be of a length that reaches the edge board 5 (described later), or they may be of a length that does not reach the edge board 5 (i.e., there may be a gap between the tips of the tongues 4a and 4b and the edge board 5). The length of the tongue 4a on the fronting side may be shorter than, longer than, or approximately equal to the length of the tongue 4b on the back side. Also, the thickness of the tongue 4a on the fronting side may be thinner than, thicker than, or approximately equal to the thickness of the tongue 4b on the back side.

[0032] In Figure 2, there are multiple tongue pieces 4, and for example, there may be a tongue piece 4a on the covering side and a tongue piece 4b on the back side (base end side in the rising direction). In the modified example of the first embodiment, the tongue piece 4a on the covering side may protrude from the upper side of the tip of the approximately L-shaped portion of the support plate 3, and the tongue piece 4b on the back side may protrude from the lower side of the tip of the approximately L-shaped portion. In the modified version of the first embodiment, the tongue 4a on the front side and the tongue 4b on the back side may be of a length that reaches the edge plate 5 (described later), or they may be of a length that does not reach the edge plate 5 (that is, there may be a gap between the tips of the tongues 4a and 4b and the edge plate 5). The length of the tongue 4a on the front side may be shorter than, longer than, or approximately equal to the length of the tongue 4b on the back side. Also, the thickness of the tongue 4a on the front side may be thinner than, thicker than, or approximately equal to the thickness of the tongue 4b on the back side.

[0033] As shown in Figure 3, there may be multiple tongue pieces 4A and 4B. For example, tongue piece 4A may include tongue piece 4Aa on the front side and tongue piece 4Ab on the back side, and tongue piece 4B may include tongue piece 4Ba on the front side and tongue piece 4Bb on the back side. One tongue piece 4Ab on the back side protrudes from the side of the crank portion (midway in the rising direction) of the one support plate 3A described above, the other tongue piece 4Bb on the back side protrudes from the side of the crank portion (midway in the rising direction) of the other support plate 3B described above, one tongue piece 4Aa on the covering side protrudes from the side of the tip of the extended portion of the one support plate 3A described above, and the other tongue piece 4Ba on the covering side protrudes from the side of the tip of the extended portion of the other support plate 3B described above. In the second embodiment, the one tongue piece 4Aa on the front side, the one tongue piece 4Ab on the back side, the other tongue piece 4Ba on the front side, and the other tongue piece 4Bb on the back side may be of a length where their tips touch each other, or of a length where they do not touch each other (that is, there may be a gap between the tip of the one tongue piece 4Aa on the front side and the tip of the other tongue piece 4Ba on the front side, and / or between the tip of the one tongue piece 4Ab on the back side and the tip of the other tongue piece 4Bb on the back side). The lengths of the one and other tongue pieces 4Aa and 4Ba on the front side may be shorter, longer, or approximately equal to the lengths of the one and other tongue pieces 4Ab and 4Bb on the back side. Furthermore, the thickness of the one and other tongue pieces 4Aa and 4Ba on the front side may be thinner, thicker, or approximately equal to the thickness of the one and other tongue pieces 4Ab and 4Bb on the back side. Furthermore, in the second embodiment, the end of the covering sheet material H can be clamped between the tip of one tongue piece 4Aa on the covering side and the tip of the other tongue piece 4Ba on the covering side, and the end of the covering sheet material H can be clamped between the tip of one tongue piece 4Ab on the back side and the tip of the other tongue piece 4Bb on the back side in the second embodiment.

[0034] As shown in Figures 1-5, the distance D between the tip of the tab 4a on the front side and the tip of the tab 4b on the back side (front-to-back distance) is not particularly limited. For example, the lower limit may be 1 mm or more or 2 mm or more, and the upper limit may be 10 mm or less or 7 mm or less (e.g., 3.7 mm or 1.1 mm). The tip of the tongue-shaped piece 4, etc., may be branched into multiple parts in a cross-sectional view. There are no particular restrictions on the material of the tongue pieces 4, etc., but for example, they may be made of a soft material as described later, and this soft material may be attached in layers to the side surface of the support plate 3, etc., between the base end of the tongue piece 4a on the front side and the tongue piece 4b on the back side. In this invention, "soft" refers to a material with a Shore hardness of 50 HS or more and 80 HS or less as defined in JIS-Z-2246:2000.

[0035] <Edge board 5> As shown in Figures 1 and 2, and Figures 4(a) and 5(a), the edge plate 5 is a plate-shaped member that rises from the substrate 2 in a cross-sectional view and is capable of clamping the end of the covering sheet material H between itself and the tip of the tongue piece 4 described above, and has a longitudinal direction (the same direction as the longitudinal direction L of the covering frame 1). The edge plate 5 may rise from the surface facing the widthwise end of the substrate 2. Furthermore, the rising height of the edge plate 5 in the first embodiment (the rising height of the covering frame 1) is not particularly limited, but may be, for example, 10 mm or more and 20 mm or less (14 mm, etc.), and the rising height of the edge plate 5 in the modified version of the first embodiment is not particularly limited, but may be, for example, 4 mm or more and 9 mm or less (7 mm, etc.). There are no particular restrictions on the material of the edge board 5, but for example, it may be made of a hard material.

[0036] <How to use the mounting frame 1> Figures 4 and 5 show a method of using the mounting frame 1 according to the present invention (hereinafter referred to as "method of use"). In this method of use, the edges of the covering sheet material H that covers the base surface S are clamped by the covering frame 1 described above. The method of use may include the temporary fixing process P1 and the final fixing process P2 described later, or it may include other processes. First, the temporary fixing process P1 and the permanent fixing process P2 will be described below.

[0037] <Temporary fixing process P1> As shown in Figure 4, the temporary fixing step P1 is a step in which, in the case of the covering frame 1 of the first embodiment, the end of the covering sheet material H is sandwiched between the tongue piece 4a on the covering side and the edge plate 5 (see Figure 4(a)), and in the case of the covering frame 1 of the second embodiment, the end of the covering sheet material H is sandwiched between one tongue piece 4Aa on the covering side and the other tongue piece 4Ba on the covering side (see Figure 4(b)). In this temporary fixing process P1, with the end of the covering sheet material H of a predetermined thickness held by the covering frame 1, it is possible (or rather, it is easy to slide along the longitudinal direction L) of the covering frame 1, making it easier to adjust the position, such as adjusting the weave direction M. The weave direction M refers to the orientation of the pattern, or the warp and weft directions of woven or knitted fabrics, if the covering sheet material H is a woven fabric, or the orientation of the pattern if the covering sheet material H is a sheet-like material such as a film made of synthetic resin (see Figure 4(b), etc.).

[0038] <Main fixing process P2> As shown in Figure 5, if the covering frame 1 is of the first embodiment, the fixing process P2 is a process in which the end of the covering sheet material H is sandwiched between the tongue piece 4a on the covering side and the tongue piece 4b on the back side and the edge plate 5 after the temporary fixing process P1 of the first embodiment (see Figure 5(a)). If the covering frame 1 is of the second embodiment, the fixing process P2 is a process in which the end of the covering sheet material H is sandwiched between one tongue piece 4Aa on the covering side and one tongue piece 4Ab on the back side and the other tongue piece 4Ba on the covering side and the other tongue piece 4Bb on the back side after the temporary fixing process P1 of the second embodiment (see Figure 5(b)). This final fixing step P2 can also be described as a step in which, in the temporary fixing step P1, with the end of the covering sheet material H of a predetermined thickness being held by the covering frame 1, the covering sheet material H is slid along a direction R that is substantially perpendicular to the longitudinal direction L of the covering frame 1, and then pushed in further, or it can be described as being difficult to slide along that substantially perpendicular direction R. As shown in Figure 5, the "substantially perpendicular direction R" in this invention may be a direction R1 that is substantially perpendicular to the longitudinal direction L of the covering frame 1 and substantially along the covering side surface (exposed surface) of the covering sheet material H, or a direction (normal direction) R2 that is substantially perpendicular to the longitudinal direction L of the covering frame 1 and substantially perpendicular to the covering side surface (exposed surface) of the covering sheet material H. This normal direction R2 of the covering side surface can also be described as a direction that pushes the covering sheet material H further into the covering frame 1 or pulls the covering sheet material H out of the covering frame 1.

[0039] <Resistive load (adjustment force) for longitudinal sliding> In the covering frame 1 and its usage described above, the resistance load when sliding the 1.20 mm thick covering sheet material H along its longitudinal direction L while clamping its end may be 60 N (Newtons) / 100 mm or less. This resistance load when sliding along the longitudinal direction L can also be called an adjustment force, as it facilitates the adjustment of the position of the fabric weave M, etc., in the covering sheet material H. It can be said that a lower value for this adjustment force is preferable, and it may be 60 N / 100 mm or less as mentioned above, preferably 43 N / 100 mm or less, and even more preferably 40 N / 100 mm or less (such as 32.29 N / 100 mm or 50.12 N / 100 mm). Up to this point, we have mentioned the upper limit of the adjustment force, but it can also be said that the lower limit is 0 N / 100 mm or more.

[0040] <Resistance load (holding force) for sliding in a nearly orthogonal direction> In the mounting frame 1 and its usage described above, the resistive load when sliding the mounting sheet material H, which is 0.15 mm thick, along a direction R that is approximately perpendicular to the longitudinal direction L, while the end of the mounting sheet material H is clamped, may be 43 N (Newtons) / 100 mm or more. This resistive load when sliding along this approximately perpendicular direction R is related to the mounting frame 1 maintaining the state in which it clamps the end of the mounting sheet material H, and can therefore be said to be a holding force. It can be said that a higher value for this holding force is preferable, and it may be 43 N / 100 mm or more as mentioned above, preferably 70 N / 100 mm or more, and even more preferably 90 N / 100 mm or more (such as 45.58 N / 100 mm or 100.28 N / 100 mm). Up to this point, we have mentioned the lower limit of the adjustment force, but it can also be said that the upper limit is 400 N / 100 mm or less. In particular, if the holding force is the resistance load when sliding the covering sheet material H in the direction of pulling it out of the covering frame 1, then the higher the value, the more it can be said that the loosening, sagging, wrinkles, and indentations that occur when touching the covering sheet material H after it has been stretched between at least two covering frames 1 can be reduced.

[0041] <Exam> In the tests of the present invention, examples and comparative examples 1 and 2 are prepared for the covering frame 1 described above, and the "adjustment force" and "holding force" for two types of covering sheet material H are investigated for these examples and comparative examples 1 and 2. First, we will explain the examples and comparative examples 1 and 2 in detail.

[0042] <Examples> The configuration of the mounting frame 1 in the embodiment is the first embodiment shown in Figure 1, with a rise height of 14.0 mm, a mounting-back distance D of 3.7 mm, and a length of 2.2 mm from the base to the tip of the tongue piece 4b on the back side.

[0043] <Comparative Example 1> Comparative Example 1 has a substrate that abuts against and is fixed to a base surface S, one support plate rising from the substrate, one substantially sawtooth-shaped uneven portion formed on the side surface of the one support plate from the middle to the tip in the rising direction, another support plate that rises from the aforementioned substrate, is bent in a substantially L-shape in the middle of the rising direction, and rises again from the tip of the substantially L-shaped portion, and the other substantially sawtooth-shaped uneven portion formed on the side surface of the rising portion of the other support plate. In the configuration of Comparative Example 1, the rise height is 22.5 mm, and since there are no multiple tongue pieces, there is no front-to-back distance D, and the height from the valley to the peak of the approximately sawtooth-shaped unevenness on one and the other is 1.0 mm.

[0044] <Comparative Example 2> Comparative Example 2 has a substrate that abuts against and is fixed to the base surface S, a support plate that rises from the substrate and is bent at approximately 45° in the middle of the rising direction, a tongue piece that protrudes from the tip of the support plate toward the substrate (downward), and an edge plate that rises from the substrate and can hold the end of the covering sheet material between itself and the side surface of the tongue piece. In the configuration of Comparative Example 2, the rise height is 26.0 mm, and since there is only one tongue, there is no front-to-back distance D, and the length from the base to the tip of the tongue that protrudes downward is 4.0 mm.

[0045] In the test, the "adjustment force" and "holding force" of the two types of surface sheet material H were measured by sliding them as shown in Figures 6(a) and (b), and the results are shown in Table 1 and Figure 7 below. Here, the longitudinal length of each of the Examples and Comparative Examples 1 and 2 is 100 mm in the measurement of "adjustment force" shown in Figure 6(a), while it is 50 mm in the measurement of "holding force" shown in Figure 6(b). Therefore, the value obtained by doubling the measurement value in Figure 6(b) is taken as the "holding force" and is shown in Table 1 and Figure 7. The measurement value in this test may be the average value of the values ​​measured for multiple (e.g., three) test pieces in each of the Examples and Comparative Examples 1 and 2. Furthermore, the substrate S for the examples and comparative examples 1 and 2 is a substantially flat surface in all cases. Furthermore, the two types of surface sheet material H are: Surface sheet material H-1 (thickness 1.20 mm, weight 379 g / m²) 2 Manufactured by Kawashima Textile Selkon Co., Ltd., 2021 product number: FT6537), surface sheet material H-2 (thickness 0.15mm, weight 120g / m²) 2 These are woven fabrics manufactured by Kawashima Textile Selkon Co., Ltd. (2021 product number: ME8280).

[0046] [Table 1]

[0047] <Evaluation of the exam> From Table 1 and Figure 7, the mounting frame 1 of the embodiment has an "adjustment force" of 60 N / 100 mm or less for mounting sheet material H-1 with a thickness of 1.20 mm, which is "32.29 N / 100 mm" or "50.12 N / 100 mm" regardless of whether it is the temporary fixing process P1 or the final fixing process P2, thus "facilitating the position adjustment of the mounting sheet material". Furthermore, the "holding force" for mounting sheet material H-2 with a thickness of 0.15 mm has an "improvement in clamping force of 43 N / 100 mm or more", which is "45.12 N / 100 mm" or "100.28 N / 100 mm" regardless of whether it is the temporary fixing process P1 or the final fixing process P2, thus "improving the clamping force of the mounting sheet material". On the other hand, the configuration of Comparative Example 1 lacks multiple tongue pieces, and therefore does not have a front-to-back distance D. Since it is held between the approximately sawtooth-shaped protrusions on one and the other, the "adjustment force" for the 1.20 mm thick front sheet material H-1 is 67.34 N / 100 mm, which exceeds 60 N / 100 mm. Therefore, it is very difficult to adjust the position of the front sheet material H-1. Furthermore, the "holding force" for the 0.15 mm thick front sheet material H-2 is 41.82 N / 100 mm, which is less than 43 N / 100 mm. Thus, it cannot reduce the occurrence of loosening, sagging, wrinkles, dents, etc., of the front sheet material H-2 stretched between at least two Comparative Example 1s. Furthermore, in the configuration of Comparative Example 2, since there is only one tongue piece, there is no front / back distance D, and the "holding force" against the 0.15 mm thick front sheet material H-2 is only "20.88 N / 100 mm", which is less than 43 N / 100 mm. Therefore, it can be said that it is not possible to reduce the occurrence of loosening, sagging, wrinkles, and indentations of the front sheet material H-2 etc. stretched between at least two Comparative Example 1s. In the embodiment, there are "adjustment force" and "holding force" in the temporary fixing process P1 and "adjustment force" and "holding force" in the main fixing process P2. However, it can also be said that only the "adjustment force" for the 1.20 mm thick surface sheet material H-1 in the temporary fixing process P1 may be 60 N / 100 mm or less, and only the "holding force" for the 0.15 mm thick surface sheet material H-2 in the main fixing process P2 may be 43 N / 100 mm or more. Furthermore, regardless of the specific values ​​of "adjustment force" or "holding force," simply having the temporary fixing process P1 and the final fixing process P2 described above (in other words, the multiple tongues 4 etc. include tongues 4a etc. on the covering side and tongues 4b etc. on the back side) can also be said to facilitate "position adjustment of the covering sheet material" and "improve the clamping force of the covering sheet material."

[0048] <Other> The present invention is not limited to the embodiments described above. The structure, shape, dimensions, and other components of the mounting frame 1 and its usage method, as well as the overall structure, can be modified as appropriate in accordance with the spirit of the present invention. The configuration of the mounting frame 1 is basically the second embodiment, but the one and the other support plates 3A and 3B do not have crank portions, extension portions, or overhang portions formed on them. Instead, after rising from the base plate 2, they may be bent in a roughly L-shape midway in the rising direction, and multiple one and the other tongue pieces 4A and 4B may protrude from the tip surface side (side surface in the rising direction) of the roughly L-shaped portion (in other words, even if it is a modified version of the second embodiment). The one and the other support plates 3A and 3B of this modified version of the second embodiment may be formed with a lower rising height than the one and the other support plates 3A and 3B of the second embodiment. The base portion in the rising direction of the support plate 3, etc., may be thinner than the crank portion or the extended portion, and its thickness may be, for example, 1.0 mm or more and 1.5 mm or less (1.2 mm, etc.). There may be three or more tongue pieces 4, one tongue piece 4A, and the other tongue piece 4B. In this case, there will be multiple tongue pieces 4a on the front side and / or multiple tongue pieces 4b on the back side. The tip of the tongue piece 4a on the covering side may be inclined downward, or the base end of this downwardly inclined portion may have a portion made of a soft material that protrudes in the opposite direction to the eaves portion of the support plate 3. A protruding portion of a hard material may be formed only on the lower side of the base end of the tongue piece 4b on the back side, and the tongue piece 4b on the back side, which is made of a soft material, may be formed above this protruding portion (in other words, the protruding portion of the hard material can be said to support the tongue piece 4b on the back side). The mounting frame 1 may be constructed integrally by extrusion molding (for example, extrusion molding via an extruder, cooling water tank, take-up machine, and cutting machine in that order), and the material constituting the mounting frame 1, or the Shore hardness of that material as defined in JIS-Z-2246:2000, may be not limited to the two types mentioned above, but may be one type or three or more types. The covering sheet material H, which is held by the covering frame 1 described above, the base surface S covered by the covering sheet material H, and the cushioning layer material C will be explained in detail below.

[0049] <Covering sheet material H> As shown in Figures 4 and 5, the covering sheet material H is a component that covers the substrate surface S, which will be described later, and can also be said to be a component stretched between at least two covering frames 1. There are no particular limitations on the thickness of this covering sheet material H, but for example, the lower limit may be 0.05 mm or more or 0.10 mm or more (e.g., 0.15 mm), and the upper limit may be 3.00 mm or less or 2.00 mm or less (e.g., 1.20 mm). Furthermore, the surface of the covering sheet material H can also be described as the side that is stretched over the covering frame 1 and exposed (exposed surface). The covering sheet material H can be in any configuration as long as it is stretched between multiple covering frames 1, but for example it may be in the form of a sheet, and the sheet-like covering sheet material H may be made of cloth, a sheet-like material such as a synthetic resin film, etc. Here, "textiles" refers to woven fabrics, knitted fabrics, nonwoven fabrics, and combinations thereof. If the covering sheet material H is a woven fabric, any weave structure is acceptable, such as plain weave, twill weave, satin weave, double weave, or multi-layer weave (double weave or more). If the covering sheet material H is knitted, it can be any of the following: warp knitting such as Denby knit (tricot knit), Raschel knit, double Raschel knit, Van Dyke knit (Atlas knit), or cord knit; or weft knitting such as plain knit (single jersey knit), rib knit, or pearl knit. If the covering sheet material H is a nonwoven fabric, it may be, for example, a needle-punched nonwoven fabric in which fibers are caught on reciprocating needles and intertwined with each other. Alternatively, it may be a thermal-bonded nonwoven fabric containing heat-fusible fibers and formed by heating, a spunbond nonwoven fabric or stitch-bonded nonwoven fabric in which long fibers (filaments) spun from a nozzle are laminated and bonded on a moving screen, etc., and bonded by a needle-punching method. When the covering sheet material H is a fabric such as a woven, knitted, or nonwoven fabric, the fibers that make up (weave, knit) them may include polyester fibers such as polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), and polybutylene terephthalate (PBT), nylon (polyamide) fibers, polyolefin fibers such as polyethylene (PE) and polypropylene (PP), rayon fibers, cupro fibers, acetate fibers, acrylic fibers mainly composed of polyacrylonitrile (PAN), synthetic fibers such as polyvinyl alcohol (PVA) fibers (vinylon fibers) and polyurethane (PU) fibers, as well as other fibers such as silk, cotton, hemp, wool, and glass fibers, and these may be used individually or in combination. Furthermore, if the covering sheet material H is a woven, knitted, or nonwoven fabric, the fineness of the fibers that make up (weave, knit) them may be any value, but for example, the total fineness should be between 20 dtex and 3000 dtex. If the surface sheet material H is a sheet-like material such as a film, the materials constituting it may include polyvinyl chloride (PVC) resin, polyester resins such as polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), and polybutylene terephthalate (PBT), synthetic resins such as polyamide (PA) resin, or these may be used individually or in combination. The covering sheet material H may be any shade of red, orange, yellow, green, blue, purple, black, or white, and its saturation and brightness may also be any value. The pattern of the covering sheet material H may also be any pattern, such as floral or plant patterns, animal patterns, geometric patterns, solid colors, or patterns created by surface irregularities. The surface sheet material H may optionally be given extender pigments or fillers such as titanium dioxide and calcium carbonate, or deodorants, antibacterial agents, antifungal agents, flame retardants, water repellents, stain repellents, colorants, fragrances, foaming agents, etc. The timing of the addition of these substances may be before or after the surface sheet material H is constructed (woven, knitted, etc.), and the method of addition may be any.

[0050] <Substrate surface S> As shown in Figures 1-5, the base surface S is the surface covered by the surface covering sheet material H described above, and can also be said to be the surface covered by the surface covering frame 1 (to which the surface covering frame 1 is attached). The base surface S may be the wall surface, ceiling surface, floor surface, or outer surface of an indoor column in a building, or it may also be the front and back surfaces of a door or a screen. The base surface S may be a nearly flat surface or a curved surface that curves along a certain direction. The covering frame 1 used to cover such a substrate S can also be considered part of the interior system (interior materials).

[0051] <Cushioning layer C> As shown in Figures 4 and 5, the cushioning layer material C is a component located between the surface sheet material H and the substrate surface S. The cushioning layer C can be in any configuration as long as it is present between the surface sheet material H and the substrate surface S. For example, it may consist of only one layer, or it may consist of multiple layers, such as a low-density layer and a high-density layer. There are no particular restrictions on the material of cushioning layer C, but it may be, for example, a fibrous web (nonwoven fabric, etc.). In particular, if the cushioning layer material C is a nonwoven fabric, as described above, it may be, for example, a needle-punched nonwoven fabric in which fibers are caught on reciprocating needles and intertwined with each other. Alternatively, it may be a thermal-bonded nonwoven fabric containing heat-fusible fibers and formed by heating, a spunbond nonwoven fabric or stitch-bonded nonwoven fabric in which long fibers (filaments) spun from a nozzle are laminated and bonded on a moving screen, etc., and bonded by a needle-punching method. When the cushion layer material C, which is a fibrous web, is a nonwoven fabric, the fibers that make up (weave, knit) them include polyester fibers such as polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), and polybutylene terephthalate (PBT), nylon (polyamide) fibers, polyolefin fibers such as polyethylene (PE) and polypropylene (PP), rayon fibers, cupro fibers, acetate fibers, acrylic fibers mainly composed of polyacrylonitrile (PAN), synthetic fibers such as polyvinyl alcohol (PVA) fibers (vinylon fibers) and polyurethane (PU) fibers, and other fibers such as silk, cotton, hemp, and wool. These may be used individually or in combination. The cushioning layer C may contain glass fibers, or it may consist solely of glass fibers (in this case, it can be said that the cushioning layer C is composed of glass wool). In addition to the materials mentioned above, the cushioning layer C may also be made of synthetic resin foam (such as urethane foam) obtained by foaming synthetic resins such as polyurethane.

[0052] The method of using the covering frame 1 may include other steps, for example, a frame installation step of attaching the covering frame 1 to the base surface S with fixing members T, etc., or a cushion installation step of providing a cushion layer material C between the covering sheet material H and the base surface S. In this case, the method of using the covering frame 1 can also be described as the method of installing the covering sheet material H (or interior system). [Industrial applicability]
