Description

The present invention relates to fasteners and fixtures for panel-shaped members.

For example, panel-shaped members such as solar cell modules installed on the roofs of buildings such as houses are known. Such a panel-shaped member is fixed to the installation surface by an appropriate fixture according to the type of roof to be installed.

Patent Document 1 discloses a plurality of solar cell panels mounted on a slope. The support unit that supports the solar cell panel has a lower member, an upper member (fastener) arranged on the lower member, and an intermediate member arranged between the lower member and the upper member ( For example, see FIG. 1A of Patent Document 1). The frame at the end of the solar cell panel is placed on the lower member and is pressed from above to below by the bent portion (pressing portion) of the upper member. As a result, the frame at the end of the solar cell panel is sandwiched between the bent portion of the upper member and the lower member. Further, in Patent Document 1, the upper member has a pair of bent portions in order to press the frames at the ends of the two solar cell panels adjacent to each other.

Japanese Unexamined Patent Publication No. 2014-173360

The inventor of the present application, when a plurality of panel-shaped members such as a solar cell module are arranged side by side, adjusts the distance between the panel-shaped members to an accurately designed value or is accurately uniform. I found it difficult to set the value. For example, depending on the condition of the roof on which the panel-shaped member is installed, it may not be possible to arrange the plurality of lower members in a straight line and accurately. In this case, the distance between the panel-shaped members adjacent to each other may be larger or smaller than a predetermined value. Further, depending on the condition of the roof, restrictions are imposed on the installation position of the fixture for fixing the panel-shaped members, and as a result of the restrictions on the positions of the panel-shaped members, the panel-shaped members adjacent to each other are also restricted. The spacing between them may deviate from the pre-designed design value.

As described above, when the spacing between the panel-shaped members varies, it may be difficult for the fastener to press the end of the panel-shaped member from above to below. Therefore, even if the spacing between the panel-shaped members varies, a fastener that easily presses the end of the panel-shaped member from above to below and a fixing tool that uses the fastener are desired.

The fastener according to one aspect includes a first pressing portion that presses the end of one of the first panel-shaped members adjacent to each other from above, and the other second panel of the panel-shaped members adjacent to each other. It has a second pressing portion that presses the end of the shaped member from above. The distance between the first pressing portion and the second pressing portion is variably configured.

The fixture according to one aspect includes the above-mentioned fastener and a support member provided with a loading portion that supports the first panel-shaped member and the second panel-shaped member from below. The first pressing portion and the second pressing portion are arranged so as to face the loading portion.

According to the above aspect, even if the distance between the panel-shaped members varies, it becomes easy to press the end of the panel-shaped member from above to below.

The panel-shaped member 10 may be, for example, a solar cell module. The panel-shaped member 10 may be installed on an installation surface 50 such as a roof of a building.

In the following, the X direction in the figure may be referred to as a horizontal direction, and the Y direction in the figure may be referred to as a vertical direction. Further, the Z direction in the figure corresponds to a direction substantially orthogonal to the installation surface or the panel of the panel-shaped member 10.

In the present embodiment, as an example, the panel-shaped member 10 is installed on an installation surface 50 having irregularities. In the example shown in FIG. 1, the installation surface 50 has a plurality of convex portions 52 extending in the vertical direction, and the plurality of convex portions 52 are arranged side by side at a predetermined pitch in the horizontal direction. As such an installation surface 50, for example, there is a roof having a seaming. In this case, the convex portion 52 corresponds to the standing seaming.

In FIG. 1, a plurality of panel-shaped members 10 are arranged side by side in the vertical direction and the horizontal direction. Not limited to the example shown in FIG. 1, the panel-shaped members 10 may be arranged along only one of the vertical direction and the horizontal direction, and only one panel-shaped member 10 may be installed.

The panel-shaped member 10 is fixed to the installation surface 50 by the fixture 100. As shown in FIG. 1, each panel-shaped member 10 may be fixed by a plurality of fixtures 100.

The panel-shaped member 10 may have a panel portion and a frame portion. When the panel-shaped member 10 is a solar cell module, the panel portion corresponds to a photoelectric conversion panel that converts solar energy into electrical energy, and the frame portion corresponds to a frame provided around the photoelectric conversion panel.

The fixture 100 may have a support member 300 and a fastener 400. The support member 300 is fixed to the installation surface 50 by a plurality of second fastening members 700. The support member 300 may extend laterally. When the installation surface 50 has the convex portions 52 as described above, the support member 300 may extend over at least two convex portions 52 in the lateral direction. The support member 300 may be sufficiently shorter than the length of the panel-shaped member 10 in the lateral direction, and may be substantially as long as the length of the panel-shaped member 10 in the lateral direction.

The support member 300 may have a substantially U-shape when viewed from the lateral direction (see FIG. 3). Specifically, the support member 300 may have a bottom portion 310 and a pair of side portions 320. The pair of side portions 320 may be erected upward from both ends in the vertical direction of the bottom portion 310. The bottom 310 and the pair of side 320s form a substantially U-shape when viewed laterally.

The support member 300 may have an upper portion extending inward in the vertical direction from the upper ends of the pair of side portions 320. The upper portion of the support member 300 constitutes a loading portion 330 that supports the end portion of the panel-shaped member 10 from below. The support member 300 may have a pair of loading portions 330 that support the ends of the panel-shaped members 10 adjacent to each other from below.

The support member 300 may have a gap 340 between the pair of loading portions 330 for passing the first fastening member 490. The first fastening member 490 fastens the support member 300 and the fastener 400 described later to each other.

The first fastening member 490 may be composed of members such as bolts and nuts. In this case, the first fastening member 490 may have a bolt including a core portion 492 and a head portion 494, and a nut 496. The diameter of the head 494 is larger than the diameter of the core 492. In this case, the size of the gap 340 in the vertical direction is preferably larger than the diameter of the core portion 492 in the vertical direction and smaller than the diameter of the head portion 494 in the vertical direction. As a result, the head 494 is maintained without coming out of the space 350 formed on the lower side of the upper portion of the support member 300.

Further, the gap 340 through which the first fastening member 490 is passed may extend in the lateral direction. As an example, the gap 340 may extend from one end to the other end of the support member 300 in the lateral direction. As a result, in a state where the first fastening member 490 is loosened, the first fastening member 490 is configured to be slidable in the lateral direction with respect to the support member 300 together with the fastener 400 described later. Thereby, the position of the fastener 400 can be adjusted according to the installation position of the panel-shaped member 10.

The fastener 400 is configured to press the end of the panel-shaped member 10 placed on the loading portion 330, for example, a frame (not shown) from above to below. In the present embodiment, the fastener 400 has a first member 420, a second member 440, and a first fastening member 490. The second member 440 may be composed of a member different from the first member 420.

The first member 420 presses the first contact portion 422 that contacts the side portion of the panel-shaped member 10 and the end of one of the first panel-shaped members of the panel-shaped members 10 adjacent to each other from above. It may have a portion 424 (see FIGS. 4 and 5).

The first contact portion 422 has a surface erected with respect to the installation surface 50 so as to abut the side portion of the panel-shaped member 10. The first pressing portion 424 is composed of a portion that projects laterally from the upper portion of the first contact portion 422. The first pressing portion 424 faces the loading portion 330 of the support member 300.

The first member 420 may have a first plate-shaped portion 426. The first plate-shaped portion 426 may be a plate-shaped portion extending from the wall portion constituting the first contact portion 422 in the direction opposite to the panel-shaped member 10 that comes into contact with the first contact portion 422. .. The first plate-shaped portion 426 faces the second plate-shaped portion 446 of the second member 440, as will be described later.

The second member 440 presses the second contact portion 442 that comes into contact with the side portion of the panel-shaped member 10 and the end of the other second panel-shaped member of the panel-shaped members 10 adjacent to each other from above. It may have a portion 444 (see FIGS. 6 and 7).

The second contact portion 442 has a surface erected with respect to the installation surface 50 so as to abut the side portion of the panel-shaped member 10. The second pressing portion 444 is composed of a portion that protrudes laterally from the upper portion of the second contact portion 442. The second pressing portion 444 faces the loading portion 330 of the support member 300, respectively.

The second member 440 may have a second plate-shaped portion 446. The second plate-shaped portion 446 may be a plate-shaped portion extending from the wall portion forming the second contact portion 442 in the direction opposite to the panel-shaped member 10 that comes into contact with the second contact portion 442. .. The second plate-shaped portion 446 faces the first plate-shaped portion 426 of the first member 420 described above. Specifically, the second plate-shaped portion 446 is located above the first plate-shaped portion 426 and overlaps the first plate-shaped portion 426 when viewed from a direction orthogonal to the plate surface of the panel-shaped member 10.

The first member 420 and the second member 440 may be fastened to each other by the first fastening member 490 at the first plate-shaped portion 426 and the second plate-shaped portion 446.

The first plate-shaped portion 426 of the first member 420 may have a first hole portion 427 through which the first fastening member 490 is passed. The second plate-shaped portion 446 of the second member 440 may have a second hole portion 447 through which the first fastening member 490 is passed. The second hole portion 447 is aligned with the first hole portion 427. The first fastening member 490 fastens the first member 420 and the second member 440 to each other through the first hole portion 427 and the second hole portion 447.

By fastening the first member 420, the second member 440, and the support member 300 to each other by the first fastening member 490, the first pressing portion 424 and the second pressing portion 444 load the end portions of the panel-shaped member 10. It will be pressed against the unit 330.

In the present embodiment, the first fastening member 490 also has a role of fastening the first member 420 and the second member 440 to each other and a role of fastening the fastener 400 to the support member 300. This makes it possible to reduce the number of members for fastening each member. Instead of this embodiment, the member for fastening the first member 420 and the second member 440 to each other may be provided separately from the member for fastening the fastener 400 to the support member 300.

In the fastener 400 of the present embodiment, the distance between the first pressing portion 424 and the second pressing portion 444 is variably configured. In other words, the first pressing portion 424 is configured to be movable relative to the second pressing portion 444. More specifically, in the fastener 400, the first member 420 and the second member 440 are attached to each other by the first fastening member 490 in a state where the distance between the first pressing portion 424 and the second pressing portion 444 is changed. It is preferable that it is configured so that it can be connected. As a result, the distance L between the first contact portion 422 and the second contact portion 442 is variably configured.

Since the distance between the first pressing portion 424 and the second pressing portion 444 is variably configured, even if the distance between the panel-shaped members 10 adjacent to each other varies, the panel-shaped member 10 It becomes easier to press the end from above to below.

For example, if the distance between the convex portions 52 of the installation surface 50 on which the panel-shaped member 10 is installed is not uniform, or if the height of the convex portions 52 is not uniform, the distance between the support members 300 may vary, or the support member 300 may be lateral. It may be installed out of direction. In this case, the distance between the panel-shaped members 10 placed on the loading portion 330 of the support member 300 may deviate from a predetermined design value. Even in this case, the distance between the first pressing portion 424 and the second pressing portion 444 is variably configured so that the first contact portion 422 and the second contact portion 442 are adjacent to each other. The side portions of the panel-shaped member 10 adjacent to each other can be pressed against the loading portion 330 by the first pressing portion 424 and the second pressing portion 444 while abutting on the side portion of the shaped member 10.

In the illustrated embodiment, the second hole portion 447 formed in the second plate-shaped portion 446 of the second member 440 extends laterally longer than the core portion 492 of the first fastening member 490 (see FIG. 7). .. As a result, the second hole portion 447 is aligned with the first hole portion 427 even when the second member 440 is laterally displaced with respect to the first member 420 to some extent. As a result, in the fastener 400, even if the distance between the first pressing portion 424 and the second pressing portion 444 is changed to some extent, the first fastening member 490 allows the first member 420 and the second member 440. Are configured to be connectable to each other.

In the above embodiment, the second hole portion 447 extends long in the lateral direction. Instead, the first hole 427 may extend laterally long. Further, the length of at least one of the first hole portion 427 and the second hole portion 447 is the diameter of the first fastening member 490 in the direction in which the first pressing portion 424 and the second pressing portion 444 are aligned, specifically. May be longer than the diameter of the core portion 492.

A plurality of positioning recesses or protrusions 428 and 448 may be formed on the surfaces of the first plate-shaped portion 426 and the second plate-shaped portion 446 facing each other. Specifically, a plurality of concave or convex portions 428 for positioning are formed on the upper surface of the first plate-shaped portion 426, and a plurality of concave or convex portions 448 for positioning are formed on the lower surface of the second plate-shaped portion 446. It is formed. Each of the plurality of positioning concave portions or convex portions 428 and 448 extends in a direction intersecting the direction in which the first pressing portion 424 and the second pressing portion 444 are arranged. The positioning concave or convex portion 428 of the first plate-shaped portion 426 may be configured to mesh with the positioning concave or convex portion 448 of the second plate-shaped portion 446.

The positioning recesses or protrusions 428,448 are used to position the first member 420 and the second member 440 with each other before fastening the first member 420 and the second member 440 with the first fastening member 490. .. As a result, when the first member 420 and the second member 440 are fastened by the first fastening member 490, the misalignment between the first member 420 and the second member 440 can be suppressed.

Instead of the above embodiment, the first member 420 and the second member 440 may not have the concave or convex portions 428 and 448 for positioning.

The first member 420 may have a leg portion 432 and a support portion 434 extending from the first plate-shaped portion 426 toward the loading portion 330. The leg portion 432 may be composed of a portion that extends continuously downward from the first contact portion 422.

The height H11 from the end of the leg portion 432 on the loading portion 330 side, that is, the lower end of the leg portion 432 to the first pressing portion 424 is the thickness of the portion of the panel-shaped member 10 pressed by the first pressing portion 424. It is preferably smaller than (Fig. 4). Similarly, the height H2 of the second member 440 from the end on the loading portion 330 side, that is, the lower end to the second pressing portion 444 is the thickness of the portion of the panel-shaped member 10 pressed by the second pressing portion 444. It is preferably smaller than (Fig. 6). That is, in a state where the first pressing portion 424 and the second pressing portion 444 are brought into contact with the panel-shaped member 10 and the fastening force is not received from the first fastening member 490, the legs 432 and the second pressing portion 420 of the first member 420 are not received. The lower end of the member 440 is in a floating state from the support member 300.

As a result, when the first member 420 and the second member 440 are fastened to the support member 300 by the first fastening member 490, the first plate-shaped portion 426 and the second plate-shaped portion 446 are directed toward the support member 300. And bend. Since a downward force is applied to the first pressing portion 424 and the second pressing portion 444, the first pressing portion 424 and the second pressing portion 444 can press the end portion of the panel-shaped member 10 more strongly.

When the first member 420 and the second member 440 are fastened to the support member 300 by the first fastening member 490, the legs 432 of the first member 420 and the lower ends of the second member 440 come into contact with the support member 300. You can. In this case, since it is possible to prevent the first plate-shaped portion 426 and the second plate-shaped portion 446 from bending significantly, the fastening force for fastening the first member 420, the second member 440, and the support member 300 is weakened. Can be deterred.

The support portion 434 of the first member 420 is provided at a position farther from the first pressing portion 424 than the leg portion 432. Further, the height H12 from the end of the support portion 434 of the first member 420 on the loading portion 330 side, that is, the lower end of the support portion 434 to the first pressing portion 424 is the first pressing portion 424 of the panel-shaped member 10. It may be smaller than or substantially the same as the thickness of the portion pressed against (FIG. 4). Preferably, the height H12 from the lower end of the support portion 434 to the first pressing portion 424 is larger than the height H11 from the lower end of the leg portion 432 to the first pressing portion 424. The difference between the height H12 and the height H11 may be, for example, about 1 mm to 5 mm.

As a result, when the first member 420 and the second member 440 are fastened by the first fastening member 490, the support portion 434 comes into contact with the loading portion 330 before the leg portion 432 comes into contact with the loading portion 330. Therefore, in the process of fastening with the first fastening member 490, the support portion 434 supports the first plate-shaped portion 426 while the first plate-shaped portion 426 bends as described above. As a result, it is possible to suppress excessive bending of the first plate-shaped portion 426 and the second plate-shaped portion 446, and to prevent a decrease in the fastening force due to the support member 300.

The leg portion 432 of the first member 420 may be provided on the first pressing portion 424 side of the first hole portion 427. On the other hand, the support portion 434 of the first member 420 is preferably provided on the side opposite to the first pressing portion 424 with respect to the first hole portion 427. As a result, when the first member 420 and the second member 440 are fastened to the support member 300 by the first fastening member 490, the support portion 434 greatly bends the first plate-shaped portion 426 and the second plate-shaped portion 446. It can be suppressed more.

This disclosure reveals to those skilled in the art various alternative embodiments, examples and operational techniques. Therefore, the technical scope of the present invention is defined only by the matters specifying the invention relating to the reasonable claims from the above description.

For example, in the above embodiment, the leg portion 432 of the first member 420 is provided on the first pressing portion 424 side of the first hole portion 427, and the support portion 434 of the first member 420 is provided on the first hole portion 427. Is provided on the opposite side of the first pressing portion 424. Not limited to this, the positions of the leg portion 432 and the support portion 434 are not particularly limited as long as the first member 420 and the second member 440 can be fastened to each other. Further, one or both of the leg portion 432 and the support portion 434 may be omitted.

Further, in the above embodiment, since at least one of the first hole portion 427 and the second hole portion 447 through which the first fastening member 490 is passed is a long hole, the first pressing portion 424 and the second pressing portion 444 The distance between them is variably configured. Instead, for example, the distance between the first pressing portion 424 and the second pressing portion 444 is variably configured by connecting the first member 420 and the second member by an elastic body such as a spring. You may. In this case, the fastener 400 may not be separated into the first member 420 and the second member 440, if possible.
