Description

Technical Field

[0001] The present invention relates to a structure for fixing a solar cell module on a coping attached to the top surface of a parapet at the end of a building roof or a gable roof.

Background Art

[0002] Recently, for the purpose of reducing the emission amount of CO2 that causes global warming, there has been an increasing interest in "self-consumption type" solar power generation in which solar cell modules are installed on the roof of a building and the generated electricity is used within the company or at home.

[0003] The roof of a building is advantageous for ensuring the amount of sunlight, but various equipment such as air conditioning equipment such as outdoor units and exhaust ducts and sanitary equipment such as water receiving tanks are installed on the roof, so it is difficult to secure a space for installing solar cell modules. In addition, since drilling work for fixing a pedestal for installing the solar cell module to the roof is required, there is a concern that the roof waterproofing function is likely to deteriorate. Further, in the mode of fixing a pedestal on the roof and installing a solar cell module, it is necessary to temporarily remove the solar cell module during the roof waterproof repair work, which takes time for the repair work.

[0004] From such a viewpoint, instead of the roof surface of a building, the upper surface of a coping covering the top surface of a parapet at the end of the roof is used as an installation place for a solar cell module. For example, the solar cell module is directly placed on the upper surface of the coping and fixed by adhesion and a metal band (see, for example, Patent Document 1), or a mechanism for supporting the solar cell module is attached to the upper surface of the coping, and the solar cell module is fixed on the mechanism (see, for example, Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0006] Among the above prior arts, in the former case where a solar cell module is installed on the upper surface of the coping, before attaching the coping to the parapet, a flexible solar cell is adhesively bonded to the upper surface of the coping in a factory in advance, and a metal band is further wound around and fixed. It does not deal with attaching a solar cell module to an existing coping by renovation work. Also, simply winding and fixing a metal band partially around the solar cell module adhesively bonded to the upper surface of the coping has a problem that it is likely to come off the coping under wind and rain.

[0007] Among the above prior arts, in the latter case, since the number of parts of the mechanism for supporting the solar cell module is large, it takes time and effort for construction. Also, the fixing of the mechanism for supporting the solar cell module is carried out by using the bent portions at both front and rear ends of the coping attached to the parapet top surface, and hooking the front and rear lower ends of the mechanism here. There is a problem that it cannot be attached to a type of coping without such a hooking portion such as a bent coping.

[0008] Also, the width of the solar cell module fixed to the upper part of the coping in both cases is limited to be substantially the same as the width of the coping. It was not possible to fix a solar cell module with a narrower width than this on a wider coping, or a solar cell module with a wider width than this on a narrower coping.

[0009] In view of such problems of the prior art, an object of the present invention is to configure a mechanism for supporting a solar cell module on a coping with a small number of component parts, and using this, to firmly fix the solar cell module on the coping regardless of the type and width dimension of the coping. Another object of the present invention is to enable fixing a solar cell module to an existing coping by renovation work.

Means for Solving the Problems

[0010] In order to solve the above problems, the present invention is a structure for fixing a solar cell module on a coping, which is attached to the coping top surface, a plurality of vertical bars are provided on the upper surface of the coping at a predetermined interval along the longitudinal direction of the coping and arranged parallel to the width direction of the coping, and at least a pair of horizontal bars respectively spanned between the upper parts of the respective vertical bars facing the tip side of the coping and between the upper parts of the rear end sides of the respective vertical bars are provided, both horizontal bars are assembled on the upper parts of the respective vertical bars fixed to the upper surface of the coping to construct a panel support mechanism on the coping, and the solar cell module is placed and fixed on the upper parts of both horizontal bars of the panel support mechanism, so that the solar cell module is configured to be held on the coping.

[0011] According to the fixing structure of the above configuration, on the upper surface of the coping attached to the coping top surface of the parapet, a plurality of vertical bars and a pair of horizontal bars are assembled in a well shape or a lattice shape to construct a support mechanism for the solar cell module, and the solar cell module arranged on the upper part of this panel support mechanism is fixed by placing its lower surface on the upper parts of both horizontal bars, so that the solar cell module can be held on the coping. The solar cell module can be fixed to both horizontal bars by using appropriate means. Three or more horizontal bars may be assembled in a well shape or a lattice shape on the plurality of vertical bars fixed to the upper surface of the coping, and the solar cell module may be fixed on these horizontal bars. The panel support mechanism is a simple structure configured by assembling a plurality of vertical bars and horizontal bars vertically and horizontally in a plan view. Without processing dedicated members to conform to the size and shape of the solar cell module, it is also possible to configure it using general-purpose members. Since the structure is simple, it can be manufactured inexpensively with a small number of component parts, and a mechanism for maintaining the solar cell module on the coping can be constructed. In addition, after the coping is attached to the coping top surface of the parapet, the panel support mechanism is attached. That is, since the panel support mechanism is performed independently of the construction of the coping, it is also possible to install the panel support mechanism on the upper surface of an existing coping to fix the solar cell module.

[0012] According to the fixing structure of the above configuration, since the solar cell module is provided to be fixed on the panel support mechanism formed by assembling vertical and horizontal cross members on the upper surface of the coping, any solar cell module with a width wider or narrower than the width of the coping can be fixed on the coping via the panel support mechanism as long as it is within the size that can be mounted on the panel support mechanism. The size of the solar cell module that can be fixed on the upper surface of the coping is not restricted by the size of the coping (width and area of the upper surface of the coping), and it can flexibly accommodate both wide and narrow copings.

[0013] In the fixing structure of the above configuration, both sides of the solar cell module can be placed on the upper parts of the two lateral cross members of the panel support mechanism, and the tip parts of the panel fixing brackets fixed to the lateral cross members are connected to both side edges of the solar cell module, so that the solar cell module can be provided to be fixed on the two lateral cross members. According to this, by placing both sides of the solar cell module on the lateral cross members, overlapping the tip of the panel fixing bracket thereon to sandwich the side edge of the solar cell module, or inserting or engaging the side edge of the solar cell module into the recess provided in the tip part of the panel fixing bracket and connecting it to the tip part of the panel fixing bracket, it is possible to firmly attach the solar cell module on the panel support mechanism.

[0014] In the fixing structure of the above configuration, in order to stably fix and attach the panel support mechanism on the coping, it is preferable to attach the base material of the panel support mechanism on the parapet top surface and attach the panel support mechanism on this base material. In the case of a coping of a type where a coping holder is attached to the parapet top surface and both end parts in the width direction are fitted and attached to this coping holder, it is possible to attach the panel support mechanism on the coping by using the coping holder as the base material of the panel support mechanism. Specifically, the vertical bars of the panel support mechanism are arranged in parallel with the coping holder fixed on the coping top surface on the coping holder, and the vertical bars are fixed and attached to the coping holder with the coping sandwiched therebetween, and the horizontal bars are assembled thereon, whereby the panel support mechanism can be constructed on the coping. In this case, it is not necessary to attach a base material for the panel support mechanism.

[0015] Further, when attaching a solar cell module to a bent coping that is not of the type that fits and attaches to a coping holder, since the strength of the holder that supports the bent coping on the parapet cannot be confirmed, it is difficult to use it as a base material for the panel support mechanism. In this case, it is preferable to fix a base material for supporting the panel support mechanism to the coping top surface. Even when attaching a solar cell module to an existing coping, regardless of whether the coping is of the type that fits and attaches to a coping holder or not, with the coping removed, a base material for the panel support mechanism is fixed to the coping top surface, and with the coping attached to the coping top surface, the panel support mechanism is supported on the base material with the coping sandwiched therebetween, whereby the solar cell module can be attached. Specifically, a base material for panel attachment is attached to the coping top surface, the vertical bars of the panel support mechanism are arranged on the base material for panel attachment, and the vertical bars are fixed and attached to the base material for panel attachment with the coping sandwiched therebetween, and the horizontal bars are assembled thereon, whereby the panel support mechanism can be constructed on the coping.

[0016] In the fixing structure of the above configuration, for the vertical bars and horizontal bars of the panel support mechanism, general-purpose members such as appropriately metal rod-shaped bodies with good weather resistance, such as steel pipes, angle materials made of stainless steel or aluminum, and square pipes, can be used. As described above, when sandwiching and fixing the solar cell module between its side edge and the tip of the panel fixing bracket attached to the horizontal cross member, if the horizontal cross member is a metal pipe having a groove on its upper surface, fasteners such as bolts and nuts for attaching the panel fixing bracket to the upper surface of the horizontal cross member can be inserted into the groove to connect the panel fixing bracket to the upper surface of the horizontal cross member. The position for attaching the panel fixing bracket to the horizontal cross member can be set appropriately along the groove, and it is preferable in that both members can be connected by a simple operation using bolts and nuts. Stainless steel or aluminum square pipes can be used as the vertical cross member and the horizontal cross member, and the two members can be connected by driving screws, which are fasteners, into the intersecting part of the two members to fix the intersecting part.

[0017] Also, in the fixing structure of the above configuration, when assembling vertical and horizontal cross members on the coping to construct a panel support mechanism and fixing the solar cell module, a gap is formed between each pair of vertical cross members that are attached in parallel with a predetermined interval on the coping below the solar cell module. Although this gap is narrow, if wind enters, the lifting force increases and there is a risk of damaging the panel support mechanism, and it also becomes a factor for generating wind noise. Therefore, it is preferable to close the gap between each pair of vertical cross members along the ends of each vertical cross member without exposing it to the outside. The closing of the gap between each pair of vertical cross members can be achieved by attaching a wind deflector along the ends of each vertical cross member to cover the gap. When fixing the solar cell module by attaching a panel fixing bracket to the horizontal cross member as described above, the gap between the ends of the vertical cross member fixed to the upper surface of the coping and the adjacent vertical cross member can be configured to be blocked by the panel fixing bracket attached to the horizontal cross member. In this case, it is not necessary to attach a wind deflector separately from the panel fixing bracket.

[0018] Also, the fixing structure of the above configuration is also applicable to a mode in which an auxiliary holder and a coping holder are integrally attached to the parapet roof surface, and the solar cell module is fixed on the coping supported by supporting both end portions in the width direction by the coping holder. The auxiliary holder is fixed to the parapet top surface integrally with the coping holder in a construction mode where it is necessary to enhance the support strength of the coping holder on which a coping, for example, wider than the width of the parapet top surface, is to be mounted. By attaching the coping holder integrally with the auxiliary holder to the parapet top surface to support the coping and further supporting a panel support mechanism on the coping with the coping holder as a base material, the strength for supporting the coping and the panel support mechanism is increased, and it becomes possible to firmly install the coping and the solar cell module on the parapet.

[0019] Moreover, the method for fixing a solar cell module on a coping attached to a parapet top surface according to the present invention is as follows. A step of fixing a plurality of coping holders at predetermined intervals on the parapet top surface; A step of attaching a coping to the parapet top surface by supporting the coping on the fixed coping holder; A step of arranging vertical rails in parallel with the coping holder on each of the coping holders fixed to the parapet top surface and fixing the vertical rails to each coping holder with the coping therebetween; A step of bridging a horizontal rail between the upper portions of the front end sides and the upper portions of the rear end sides of the respective vertical rails facing the front end side of the coping and fixing both horizontal rails to the upper portions of the respective vertical rails; A step of placing and supporting a solar cell module on the upper portions of both horizontal rails; A step of connecting both side portions of the solar cell module to the tip portions of panel fixing brackets fixed to the horizontal rails and fixing the solar cell module on both horizontal rails. It is possible to fix the solar cell module on the coping through the construction steps including these.

Advantages of the Invention

[0020] According to the present invention, a support mechanism for a solar cell module is constructed by assembling a plurality of vertical rails and a pair of horizontal rails in a well shape or a grid shape on the upper surface of a coping attached to the top surface of a parapet, and by placing and fixing a solar cell module on the upper portion of this panel support mechanism, the solar cell module can be held on the coping. The panel support mechanism installed on the upper surface of the coping is a simple structure composed of a plurality of vertical bars and horizontal bars assembled vertically and horizontally in plan view. By using general-purpose members and manufacturing at low cost with a small number of component parts, it is possible to install a solar cell module on the coping. Since the panel support mechanism is carried out independently of the construction of the coping, it is possible to install the panel support mechanism on an existing coping to fix the solar cell module. Moreover, as long as it is a solar cell module that can be mounted on the panel support mechanism, it is not limited to the size of the coping, and solar cell modules of any size, wider or narrower than the width of the coping, can be fixed on the coping via the panel support mechanism. By using the upper surface of the coping attached to the top surface of the parapet as an installation area for the solar cell module, it becomes unnecessary to install a pedestal for the solar cell module on the rooftop, there is no risk of deteriorating the rooftop waterproofing function, the rooftop waterproofing repair work can be carried out without much effort, and it is possible to effectively utilize the rooftop of the building.

Embodiments for Carrying Out the Invention

[0022] A preferred embodiment of the fixing structure of the solar cell module of the present invention will be described with reference to the drawings. Note that the technical idea of the present invention is not limited to the embodiments described below.

[0023] FIG. 1 shows a schematic side section of a state in which a solar cell module is fixed to the upper part of a coping by applying the fixing structure of an embodiment of the present invention. In the illustrated form, a coping 1 having substantially the same width as the width of the top surface is attached to the top surface of a parapet P provided at the end of the roof of a building, a panel support mechanism 3 is attached on this coping 1, and the solar cell module SM is fixed above the panel support mechanism 3 and configured to be held on the coping 1.

[0024] Specifically, a plurality of coping holders 2 are fixed to the top surface of the parapet P by driving fixing tools S such as anchor bolts at predetermined intervals along the longitudinal direction thereof and arranged in parallel with the width direction of the top surface. Both end portions in the width direction of the coping 1 covering the top surface of the parapet P are fitted to the front and rear end portions of each coping holder 2, and the coping 1 is supported on each coping holder 2 and attached to the top surface of the parapet P.

[0025] The panel support mechanism 3 includes a plurality of vertical bars 4 that are arranged at predetermined intervals along the longitudinal direction of the coping 1 on the upper surface of the coping 1 and are parallel to the width direction of the coping 1, and upper portions between the vertical bars 4 facing the tip side of the coping 1 and upper portions between the rear end sides of the vertical bars 4. It is configured to include horizontal bars 5 spanned therebetween and panel fixing fittings 6 attached to both of the horizontal bars 5.

[0026] Specifically, as shown in FIG. 2, both the vertical and horizontal bars 4 and 5 are pipe materials made of aluminum profiles having a substantially C-shaped or U-shaped cross section with grooves on the upper surface. A fixing tool S such as a screw is inserted from the groove, or a nut or bolt that is the fixing tool S is inserted into the groove, and this is fastened to bolts or nuts arranged on the groove, so that they are connected to other members respectively. In the illustrated form, the vertical bar 4 is formed to have a length slightly larger than the width dimension of the solar cell module SM, and the horizontal bar 5 is formed to have a dimension larger than the longitudinal dimension of the solar cell module SM. Further, as shown in FIG. 3, the panel fixing fitting 6 is made of a long angle material having the same length as the horizontal bar 5, with the tip portion 62 on one side of the base portion 61 placed on the upper surface of the horizontal bar 5 bent in an L shape. A plurality of hole portions 61a into which a fixing tool S such as a bolt is inserted are opened in the plane of the base portion 61, and a wind shielding piece portion 63 bent downward is integrally provided at the end portion on the other side of the base portion 61.

[0027] As shown in FIG. 1, the panel support mechanism 3 arranges the vertical bars 4 on the coping 1 in parallel with the respective coping holders 2 fixed on the parapet P, and fastens and fixes the vertical bars 4 to the coping holders 2 with a fixing tool S such as a screw with the coping 1 interposed therebetween. The horizontal bars 5 are respectively spanned between the upper portions facing the tip side of the coping 1 and the upper portions of the rear end side of the vertical bars 4 fixed on the coping 1, and are connected with fixing tools S such as bolts and nuts on each vertical bar 4. The vertical and horizontal bars 4 and 5 are assembled in a well shape or a lattice shape to be constructed on the coping 1. Then, both side portions of the solar cell module SM disposed on the upper portion of the panel support mechanism 3 are placed on the upper portions of the both horizontal cross members 5, and panel fixing brackets 6 are respectively applied from above both side portions of the solar cell module SM. Further, side edge portions of both side portions of the solar cell module SM are sandwiched between the upper surface of the horizontal cross member 5 and the tip portions 62 of the panel fixing brackets 6, and the base portion 61 of the panel fixing bracket 6 is fastened with a nut to a bolt passed through a hole portion 61a formed in the surface thereof into the groove of the horizontal cross member 5, thereby fixing the panel fixing bracket 6 to the horizontal cross member 5 using a fixing tool S. Thus, the solar cell module SM is fixed to the panel support mechanism 3 and held on the coping 1. With the panel fixing brackets 6 fixed to the both horizontal cross members 5, gaps between end portions of adjacent vertical cross members 4 fixed to the upper surface of the coping 1 are blocked by wind shielding pieces 63 of the panel fixing brackets 6, and wind does not enter the gaps.

[0028] FIG. 4 shows a form in which an auxiliary holder 7 and a coping holder 2 are integrally attached to the top surface of a parapet P, and a panel support mechanism 3 similar to the above form is constructed on the coping 1 supported by attaching both end portions in the width direction to the coping holder 2, and the solar cell module SM is fixed to the upper portion of the panel support mechanism 3.

[0029] The process of attaching the coping 1 and the solar cell module SM of the present form will be described with reference to FIGS. 5, 6, and 7. First, as shown in FIG. 5(A), a plurality of auxiliary holders 7 are arranged on the top surface of the parapet P at predetermined intervals along the longitudinal direction thereof and in parallel with the width direction of the top surface, and each is fixed to the parapet P by driving a fixing tool S. Next, as shown in FIG. 5(B), the coping holder 2 is overlapped with a recess provided in the center of each of the auxiliary holders 7, and similarly, a fixing tool S is driven to fix it to the parapet P integrally with the auxiliary holder 7. Then, as shown in FIG. 5(C), the coping 1 is placed on the top surface of the parapet P, both end portions in the width direction of the coping 1 are fitted to the front and rear end portions of each of the coping holders 2, and the coping 1 is supported on each of the coping holders 2 and attached to the top surface of the parapet P.

[0030] If the coping 1 is attached to the parapet P, as shown in Fig. 6(A), the vertical cross members 4 are arranged on the coping 1 in parallel with each coping holder 2 fixed on the parapet P, and the vertical cross members 4 are fastened and fixed to the coping holders 2 with fasteners S with the coping 1 sandwiched therebetween. Next, as shown in Fig. 6(B), the horizontal cross members 5 are respectively spanned over the upper part of each vertical cross member 4 facing the tip side of the coping 1 and the upper part of the rear end side, and are connected to each other on each vertical cross member 4 with fasteners S, and the vertical and horizontal cross members 4, 5 are assembled in a well shape or a lattice shape to construct the panel support mechanism 3 on the coping 1. Then, as shown in Fig. 6(C), the solar cell module SM is placed on the panel support mechanism 3. Similarly to the above, the side edge portions on both sides of the solar cell module SM are sandwiched between the upper surface of the horizontal cross member 5 and the tip portion 62 of the panel fixing fitting 6, and the panel fixing fitting 6 is fixed to the horizontal cross member 5, so that the solar cell module SM can be fixed to the panel support mechanism 3 and held on the coping 1. Note that Fig. 7 shows an external view in which the main part is broken so that the inside of the coping 1 and the panel support mechanism 3 shown in Fig. 4 can be seen.

[0031] Fig. 8 shows a form in which, as the vertical and horizontal cross members 4, 5, square pipes having a rectangular cross section are used instead of the pipe materials having grooves on the upper surface shown in Fig. 2, the two cross members 4, 5 are assembled in the same manner as above to construct the panel support mechanism 3 on the coping 1, and the solar cell module SM is fixed to the upper part of this panel support mechanism 3. As shown in Fig. 9(A), both the vertical cross members 4 and the horizontal cross members 5 are made of angle pipes formed from aluminum profiles cut to appropriate lengths. In the same manner as the construction procedure shown in Fig. 6, the vertical cross member 4 is arranged on the coping 1 parallel to the coping holder 2 fixed on the parapet P. With the coping 1 sandwiched therebetween, the vertical cross member 4 is fastened and fixed to the coping holder 2 with screws, which are the fixing tools S. Next, the horizontal cross members 5 are respectively spanned over the upper part facing the tip side of the coping 1 and the upper part of the rear end side of each vertical cross member 4, and screws, which are the fixing tools S, are fastened on each vertical cross member 4 for connection. The vertical and horizontal cross members 4 and 5 are assembled in a well shape or a lattice shape to construct the panel support mechanism 3 on the coping 1. Further, the solar cell module SM is placed on the panel support mechanism 3, and by fixing the panel fixing bracket 6 to the horizontal cross member 5 in the same manner as above, the solar cell module SM is held on the coping 1. In this case, for the fixation of both cross members 4 and 5 that intersect vertically and horizontally with screws, as shown in Fig. 9(B), a hole portion 5a through which the screw passes is formed at the position where the screw is fixed within the upper surface of the upper horizontal cross member 5. The screw (fixing tool S) passed through this hole portion 5a is screwed into the lower surface portion of the horizontal cross member 5 overlapping vertically and the upper surface portion of the vertical cross member 4 to connect both surfaces.

[0032] Also, as a modified example of the horizontal cross member 5, for example, as shown in Fig. 10(A), a long steel material or aluminum profile with a U-shaped cross section is used as the horizontal cross member 5, and the panel fixing brackets 6 with their tips bent in an L shape are connected to a plurality of holes formed on its upper surface, and the side edge portion of the solar cell module SM may be sandwiched and fixed between the tip portions of each panel fixing bracket 6 and the upper surface of the horizontal cross member 5. Alternatively, as shown in Fig. 10(B), a panel fixing bracket 6 of the same length as this may be connected to the horizontal cross member 5 with a U-shaped cross section to sandwich and fix the side edge portion of the solar cell module SM. In these cases, the fixing position of the panel fixing bracket 6 is restricted to the position of the hole formed on the upper surface of the horizontal cross member 5. However, as shown in Fig. 10(C), if a pipe material having a groove on the upper surface is used as the horizontal cross member 5, the fixing position of the panel fixing bracket 6 can be set at a desired position along the groove of the horizontal cross member 5, and the two members can be connected with bolts and nuts by a simple operation.

[0033] FIG. 11 shows a mode of attaching a panel mounting base material to the top surface of a parapet in order to fix a solar cell module to an existing coping. The panel mounting base material 8 is a member for attaching a panel support mechanism constructed on the coping to the top surface of the parapet P. For example, as shown in FIG. (C) of the same drawing, a steel plate bent in an L-shape or a U-shape can be used. The panel mounting base material 8 is attached in a state where the existing coping is temporarily removed to expose the top surface of the parapet P. As shown in FIGS. (A) and (B) of the same drawing, it is appropriately arranged between the existing coping holders 2, 2, and a fixing tool S such as an anchor bolt can be driven in to fix it to the top surface of the parapet P. Once the panel mounting base material 8 is fixed to the top surface of the parapet P, the coping 1 is reinstalled and attached to the top surface of the parapet P. The vertical strut 4 of the panel support mechanism 3 is arranged on the panel mounting base material 8 from above the coping 1, and the vertical strut 4 is fixed and attached to the panel mounting base material 8 with the coping 1 sandwiched therebetween. Then, by assembling the horizontal struts 5, 5 on the vertical strut 4, the panel support mechanism 3 can be constructed on the coping 1, and the solar cell module SM can be held on the coping 1. Even when a bent coping is attached to the top surface of the parapet P, the panel mounting base material 8 can be attached to the top surface of the parapet P in the same manner as described above, and the solar cell module SM can be fixed to the coping.

[0034] In the illustrated form, the side edge portions on both sides of the solar cell module SM arranged at the upper part of the panel support mechanism 3 are sandwiched between the upper surface of the horizontal strut 5 and the tip portion 62 of the panel fixing fitting 6 to fix the solar cell module SM. However, the fixing means of the solar cell module SM arranged on the panel support mechanism 3 is not limited to this, and appropriate means can be used. A recess can be formed at the tip portion of the panel fixing fitting 6 into which the side edge portion of the solar cell module SM fits, and the solar cell module SM can be fixed on the panel support mechanism 3 by inserting or engaging the side edge portion into this recess for connection. Also, the solar cell module SM and the vertical strut 4 may be connected and fixed.

[0035] The above-described configurations of the coping 1, coping holder 2, auxiliary holder 7, and panel support mechanism 3 constructed on the upper part of the coping 1 and the forms of its constituent members are examples, and the present invention is not limited to the illustrated configurations and forms, and other appropriate configurations and forms are possible. Further, the fasteners S used for connecting, joining, and fixing the members are not limited to those illustrated, and various fasteners such as screws, bolts and nuts, anchor bolts, and screws in appropriate forms can be used.
