Description

FRAME ASSEMBLY AND SOLAR MODULE ASSEMBLY

The invention relates to a frame arrangement for at least one solar module. The frame assembly has a frame which has a front side, a rear side facing away from this, a top bar and parallel thereto, to be arranged closer to the ground during installation as the top bar and which is adapted to receive a solar module. Furthermore, the invention relates to a profile rail having a bottom surface and at least one support piece, which has a bearing surface oriented away from the bottom surface for placing a not counting to the rail rail frame assembly according to the invention. Moreover, the invention relates to a solar module assembly with two parallel mounted according to the invention rails and a plurality of each mounted on the two rails in a row frame assemblies according to the invention.

Solar modules are typically either photovoltaic modules that generate electrical energy when sunlight falls, or solar collector modules that heat a passing fluid when exposed to sunlight. Thus, sunlight can be converted into a usable form of energy. From a variety of solar modules and suitable fasteners, a solar module assembly can be constructed to take advantage of an existing area. Frame assemblies and rails are used to construct solar module assemblies. These are placed in an on-roof system on an existing roof, such as a tiled roof. In contrast, in an in-roof system, roof panels are removed and at least partially replaced by the solar module arrangement. The roofs on which such solar module assemblies are mounted, are usually pitched roofs, as found in a variety of single and multi-family homes.

To assemble a solar module assembly, workers must spend all needed parts on the pitched roof and assemble under difficult conditions. Due to the roof pitch, there is a risk that parts, such as mounted on rails mounting frame, can fall and cause damage or injury. Therefore, it is desirable to provide a solar module assembly in which the risk of parts falling down during assembly is reduced.

This is achieved according to a first aspect of the invention by a frame assembly according to claim 1. According to a second aspect of the invention, this is achieved by a rail according to claim 10. According to a third aspect of the invention, this is achieved by a solar module arrangement according to claim 13. Advantageous embodiments can be obtained, for example, from the dependent claims. According to the first aspect, the invention relates to a frame arrangement for at least one solar module. This has a frame, which has a front side facing away from this rear side, a top bar and parallel thereto, to be arranged closer to the ground during installation as the top bar and which is adapted to receive a solar module. The frame assembly further comprises at least one on the back of the frame connected to this or firmly connectable holding piece, which has a holding profile for producing a single positive connection with a complementary second holding profile of a support piece of a non-frame assembly rail in an assembled state. In this mounting state, the positive connection limits or prevents a movement of the frame assembly in a direction pointing from the top bar to the bottom bar and in a direction pointing from the bottom bar to the top bar opposite direction. The frame assembly according to the first aspect of the invention is preferably used together with a profile rail according to the second aspect of the invention, which has the mentioned complementary second retaining profile. When the frame assembly is placed with the holding piece on the second holding profile, the profiles engage in such a manner that slipping of the frame assembly is prevented. Although in this state, the frame assembly is not yet secured against a possible lifting of the rail, but this can be done easily via later described end and intermediate holder. This assembly is particularly advantageous in heavy solar modules, since they can be stored in almost final position on the roof or on the rack system and against slipping and against displacement, for. B. by wind, are secured in the opposite direction. The final fixation, z. B. by a clamp, can be done in a second operation. This increases safety when working on the roof.

The frame is typically made of metal, for example aluminum. In the simplest case, it consists of four rectangular strips, which can accommodate or insert a solar module.

It is not necessary for a frame to recognize immediately which bar is the top bar or bottom bar. A frame may also be designed such that it can be mounted in a plurality of positions, for example in four positions each rotated by 90 ° relative to one another in a solar module arrangement. Other angles may be possible, but this would typically result in poorer utilization of the available area for rectangular frames. At the latest when mounted on the roof, however, results in which bar is the top bar and in which it is the bottom bar, as solar modules are typically mounted diagonally for better utilization of sunlight. For example, they are mounted at the same angle as the roof supporting them.

The holding piece can be designed in various ways. For example, the holding piece may be formed as an integral part of the frame. In this case, a bar of the frame may have been provided by suitable processing with the holding profile. The holding piece is then not removable from the frame. The holding piece can also be formed in that the holding profile is formed in a surface portion of the back of the frame. Also in this case, the holding piece is not removable from the frame.

Alternatively, the holding piece is designed as a holding strip different from the frame, which is releasably connected in the assembled state with the frame. The retaining strip preferably has an elongated shape and has on one side, which in the assembled state in the same direction as the back of the frame, the retaining profile. To attach the retaining strip to the frame, the retaining strip can be provided with a hole through which a screw, a bolt or a similar fastener can be performed to connect the retaining strip with the frame.

The execution of the holding piece from the frame of various retaining strips offers the particular advantage that it is possible to use commercially available frames and to provide them only during assembly at the construction site with the retaining strip. In one embodiment of the retaining strip with a through hole only a suitable hole or hole must be formed in the frame, so that a connection of the retaining strip to the frame is possible. Since the holding profile formed on the retaining strip has a certain extent, the positioning of the hole to be drilled at the construction site in the frame is not required to be particularly stringent. Since the retaining strip is placed in the assembled state on a mounting rail, which usually has a considerably smaller extent than the retaining strip, an approximate positioning of the hole is sufficient such that it is approximately at the location of the rail in the assembled state. However, a deviation from the position of the rail plays no role, as long as the retaining profile still rests on the rail.

Alternatively, the retaining strip can be attached to the frame without screwing. This can be done for example by jamming or sticking.

According to one embodiment, the frame assembly comprises two holding pieces. These are preferably arranged on opposite, transverse to the top bar extending sidebars of the frame, each with approximately the same distance from the top bar. As a rule, it is crucial for the assembly that both holding pieces are formed at least over a profiled rail lying below the rear side of the frame, so that the frame rests on the profiled rail with two holding pieces and the respective holding profile. It should be mentioned here, however, that a retaining piece is sufficient for the frame to prevent slipping. In this case, the frame, for example, with a side bar to which no holding piece is attached, adjacent to a flat area. For example, the frame can be secured against twisting and slipping so that it borders directly on a laterally adjacent frame.

According to a further embodiment, the frame has three or four holding pieces with the holding profile. Particularly preferably, it has four holding pieces, wherein in each case two holding pieces are arranged on opposite, transverse to the top bar side rails of the frame, each with approximately the same distance from the top bar. In other words, the holding pieces in this case form approximately the four corners of a rectangle. Thus, the frame can be placed on two suitable rails mounted parallel to each other, wherein two holding pieces rest on a first of the rails and rest two more holding pieces on a second of the rails. The holding effect is achieved at the same time on all four holding pieces. If the frame has a plurality of holding pieces, they may be formed in various ways, as already described above, as in the case of a holding piece.

Preferably, the retaining profile in each case a plurality of alternately arranged, parallel to the lower edge extending valleys and ridges. This can be achieved, for example, in that the retaining profile is toothed or corrugated. In this case, the ridges stand off the back, while the valleys form pits between the ridges. Such a toothed or corrugated profile can easily be placed on a complementary profile, so that the required holding effect according to the invention is achieved. Preferably, a respective lying between a valley and an adjacent, further away from the lower ridge comb surface of the holding profile forms a holding surface for a corresponding surface of the complementary second holding profile. In other words, this means that such a holding surface engages with a corresponding surface of the complementary second holding profile, so that movement of the frame assembly in the direction pointing from the top bar to the lower bar direction is prevented. Since an obliquely mounted frame already rests with its weight on a rail and is pressed by gravity down, first a holder of the frame in the opposite, so pointing upwards direction is not necessary. In a toothed or corrugated profile, however, a holding effect is typically achieved in these two directions, because of in each case the surfaces opposite complementary surfaces mentioned complementary surfaces cooperate in a similar manner to prevent movement of the frame. Thus, any possible movement of the frame in spite of the weight can be prevented in a direction pointing from the lower strip to the upper strip, for example in the case of wind.

The frame assembly may include a solar module received in the frame such that an active area of the solar module may be illuminated by incident light from the front of the frame. Such a frame arrangement with a solar module can also be referred to as a framed solar module. The solar module can be mounted, for example, on the frame, so that the solar module covers the frame and thus the frame is no longer visible in the mounted state from the front. Likewise, however, the solar module can also be accommodated within the frame, so that the solar module is surrounded by the frame. In this case, the frame would still be visible even in the assembled state. According to a second aspect, the invention relates to a profiled rail with a bottom surface and at least one support piece, which has a bearing surface oriented away from the bottom surface for laying a not counting to the profile rail frame assembly according to the first aspect of the invention. The bearing surface in this case has a second retaining profile for producing an exclusively positive connection with a complementary retaining profile of a retaining piece of the frame assembly in an assembled state, wherein in this mounting state, the positive connection movement of the frame assembly in a direction transverse to a longitudinal direction of the rail and in a plane the bearing surface lying limited or prevented. The rail according to the second aspect of the invention is preferably used together with a frame assembly according to the first aspect of the invention. From a plurality of profile rails and frame arrangements according to the second or first aspect of the invention, a solar module arrangement according to the third aspect of the invention can be constructed. Already in connection with the frame arrangement according to the first aspect of the invention, it has been described which advantages result during assembly. The possible embodiments of the retaining profile already mentioned with reference to the retaining profile of the frame arrangement apply correspondingly to the second retaining profile of the profile rail. In particular, the second retaining profile preferably has in each case a plurality of alternately arranged valleys and ridges running parallel to the longitudinal direction of the profile rail. The second retaining profile is preferably formed serrated or wavy. Between the valleys and crests, the corresponding surfaces can be formed, for which complementary retaining surfaces are formed in the retaining profile of the frame assembly.

According to one embodiment, the rail on at least one of its longitudinal ends on a telescopic rod, which is extendable from the rail, and which has another support piece with the second retaining profile, whereby at least partially extended telescopic rod, the support piece on the longitudinal end of the rail out through the second Pad is extended. The telescopic rod makes it possible to extend the support piece of the rail in the longitudinal direction. On the one hand, an adaptation to the widths of frames can thus be made, ie it is not necessary to adapt rails exactly to frame arrangements to be mounted thereon. On the other hand, it is also possible to mount end holder on the telescopic rod and to bring by inserting the telescopic rod in the rail in engagement with a frame assembly, which is at the end of a series of frame assemblies. The other support piece has as well as the profile rail, the second holding profile, wherein the profiles are preferably designed such that the second holding profile of the other support piece with proper insertion of the telescopic rod in the rail represents a structural and functional continuation of the second holding profile of the support piece. In other words, this means that a frame assembly with a retaining profile can also be placed on the support piece of the rail, on the other support piece of the telescopic rod, or on a region in which overlap the support piece of the rail and the other support piece of the telescopic rod, and forms the mentioned form-fitting connection. Alternatively, however, can be dispensed with the telescopic pole. In this case, frames rest directly on the support piece of the rail and the end bracket is mounted directly on the rail. The profile rail preferably has a receiving space in which the telescopic rod can be inserted. The receiving space may for example have a constant in the longitudinal direction of the rail profile. In addition, it can have an opening which divides the support piece into a first support piece and a second support piece. In this case, the telescopic rod may for example be designed so that it, when it is inserted into the receiving space, at least partially forms its further support piece between the first support piece and the second support piece.

According to a third aspect, the invention relates to a solar module arrangement with two mutually parallel rails mounted according to the second aspect of the invention and a plurality of each mounted on the two rails in a row frame arrangements according to the first aspect of the invention. Thus, for the solar module arrangement, in particular during the assembly of the solar module arrangement, the advantages already described in connection with the frame arrangement and the profile rail are made possible.

The frame arrangements are typically mounted directly next to each other. They are on each with at least one holding piece on one of the rails. Preferably, a frame with two holding pieces formed on opposite side strips rests on a profile rail. Particularly preferred is a frame with two more, formed on opposite side rails of the frame holding pieces on the other rail. In this case, this frame is located on the rails with a total of four holding pieces.

At least one of the profiled rails is preferably a profiled rail of the type described above, which has a telescopic rod. In the assembled state, the telescopic rod is preferably partially pulled out, wherein at least one of the holding pieces of one of the frame arrangements rests on the further holding piece and an end holder holding this frame arrangement is mounted on the telescopic rod.

Such an end holder may for example comprise a rod-shaped main body and a hook, wherein the rod-shaped main body has a hole through which a fastening means such as a screw or a bolt is inserted and which is positively or non-positively connected to a bore provided in the telescopic rod. If such an end holder is not mounted on a telescopic pole, it can also be mounted on one longitudinal end of the profile rail. However, this requires that the length of the rails is matched to the exact width of the row of frames to be mounted. By using telescopic rods, this requirement can be avoided.

According to a preferred embodiment, both profile rails of the solar module arrangement are a profile rail of the type described above, which has a telescopic rod.

In accordance with a further preferred embodiment, in the case of the solar module arrangement, those of the frame arrangements, which each have two adjacent frame arrangements, have their at least one retaining piece on one of the support pieces of the profile rails. Further, a middle holder is preferably mounted between adjacent side rails of the frame of the adjacent frame assemblies, which holds these frame assemblies in a direction transverse to the support surface form-fitting manner. In addition, it is further preferred that an end holder is mounted on each of the side rails to which no further frame arrangement is adjacent.

The assembly of the end holder and the center holder is in this case preferably carried out so that the end holder or center holder with the rail forms a positive or non-positive connection, which prevents him from moving away from the rail. In the case of the center holder this can be done for example by means of a holding profile, which is adapted to the profile of the rail. This can be dispensed with the usual screwing the center holder, whereby the center holder needs to have only one component. This allows easier installation without pre-assembly. In addition, the space required by the center holder between the modules is reduced. For example, thus reduces the necessary distance between the modules of about 20 mm to about 10 mm, which not only leads to a better aesthetics of the entire system, but also to a better use of space.

An end holder can be designed as already described above. Then, an end holder or a center holder may preferably have a hook, a plurality of hooks or a continuous holding plate which engages on a front side of one or two frames respectively. This prevents the frames from falling off the profile Remove the rail in one direction across a plane of the overlay. This is necessary in order to design the solar module arrangement such that it does not involve the risk of falling solar modules even in strong winds. Since the frames are already held in a direction pointing from the top bar to the bottom rail direction, ie in a plane of the support piece pointing in the direction of the ground and press with their weight in this direction, the frames are thus secured against slipping as well as against lifting. When using a holding profile according to the first aspect of the invention, the frames are also secured against sliding upwards.

According to one embodiment, the solar module arrangement is further connected to a further solar module arrangement according to the third aspect of the invention, wherein respective profiled rails adjoin one another in the longitudinal direction and are connected by means of a connector. Such a connector may preferably have two parts, wherein in each case a part is designed to be inserted into a cavity of a profile rail, for example the already mentioned receiving space.

In this embodiment, solar module assemblies according to the third aspect may be strung together to provide rows of solar modules that are longer than the lengths of respective profile rails. This allows easier transport of rails, as they can be chosen shorter, and also easier installation.

Further advantages and features of the invention will become apparent upon consideration of the following embodiments, which are attached with reference to the following attached drawings:

Fig. 12 shows a solar module assembly according to the third aspect of the invention.

Fig. 1 shows a frame assembly 100 according to the first aspect of the invention. The frame assembly 100 includes a frame 200 having a top rail 210, a bottom rail 220, a right side rail 230, and a left side rail 240. These together form a rectangular structure.

The frame has a front side 1 10 and a rear side 120, which is not visible in FIG. 1. In the frame 200, a solar module 130 is accommodated so that it can be illuminated by light incident on the front side 1 10. In the present case, the solar module 130 is a photovoltaic module.

The solar modules are partially transparent in some figures to show underlying elements.

FIG. 2 shows the frame arrangement 100 shown in FIG. 1 in a rear view.

In Fig. 2, therefore, the back 120 is visible. The frame 200 has four holding pieces 300, 310, 320, 330. The holding pieces 300, 310 are attached to the right side strip 230, while the holding pieces 320, 330 on the left side strip 240 are attached. The holding pieces 300 and 320 or the holding pieces 310 and 330 are in pairs opposite each other. In other words, this means that they each have the same distance from the top bar 210 in pairs.

It should be mentioned that at least one retaining piece is required to ensure a function of slip-off protection.

By way of example, FIG. 3 shows the retaining piece 300 in greater detail. The retaining piece 300 is formed as a retaining strip 400, which is mounted on the right side rail 230. For mounting, a through hole 410 is used, through which a screw (not shown) for attachment to the right side rail 230 can be performed. The retaining strip 400 has a holding profile 305 which is formed on a side of the retaining strip 400 opposite the right side strip 230.

As an alternative to mounting the holding piece 300 by means of a screw made through the through hole 410, it would also be possible to clamp or glue the holding strip to a frame. The retaining profile 305 is embodied toothed and shown in Fig. 4 in more detail. Fig. 4 shows the holding profile 305 as it would preferably be mounted on a pitched roof or an inclined surface, d. H. with overhead frame 200. The retaining profile 305 is formed toothed here. In doing so, valleys 420, which are formed as depressions, alternate with combs 430, which protrude away from the retaining strip 400, alternately. The distances between the valleys 420 are the same in the present case, as are the distances between the combs 430. It is crucial that the profile is formed complementary to the profile on which it is intended to rest. In each case between a valley 420 and an adjacent comb 430 further away from the lower strip, a holding surface 440 is formed. This support surface 440 would prevent the laying of the retaining strip 400 on a suitable complementary second retaining profile, which is not shown in Fig. 4, a slippage of the frame 200 in the direction of the earth's surface.

Fig. 5 shows a profile rail 1000 according to the second aspect of the invention. The profile rail 1000 has a longitudinal direction 1010, along which its profile is unchanged. The rail 1000 has a mounting portion 1 100, on which a bottom surface 1 1 10 is formed. With the bottom surface 1 1 10, the rail 1000 can be mounted, for example, on a roof hook adapter for mounting on a roof hook. The profile rail 1000 also has a first support piece 1200 and a second support piece 1210. These together form a mounting portion 1220. Further, the first pad 1200 and the second pad 1210 provide a bearing surface 1230. On this bearing surface 1230, a holding piece of a frame assembly according to the first aspect of the invention can be placed. On the first support piece 1200 and the second support piece 1210, a second holding profile 1300 is formed. The second retaining profile 1300, when a retaining piece is placed with a complementary retaining profile 305 of a frame assembly 100 according to the first aspect of the invention, prevent slippage of the frame assembly 100 in a holding direction 1310. Like the holding profile 305 of the holding piece 300 shown in FIG. 4, the second holding profile 1300 is toothed. Here, valleys 1320 alternate with combs 1330. Again, the complementarity to the profile with which the profile is to be engaged, crucial. A holding surface 1340 is formed between a valley 1320 and a comb 1330 adjacent in the holding direction 1310, which when engaging a holding piece 300 engages with a complementary holding profile 305 with a corresponding holding surface 440 and prevents the frame assembly 100 from slipping in the holding direction.

Furthermore, the profile rail 1000 has a receiving space 1400 in which a telescopic rod can be inserted.

A suitable telescopic rod 1500 is shown in Fig. 6. The telescopic rod 1500 has a profile through which it can be inserted into the receiving space 1400 of the rail 1000.

The telescopic rod 1500 has a further support piece 1550 on one side. The further support piece 1550 is, like the first support piece 1200 and the second support piece 1210 provided with the second holding profile 1300. In other words, this means that the surface of the further support piece 1550 is structured as well the surface of the first pad 1200 and the surface of the second pad 1210.

Furthermore, the telescopic rod 1500 has a through hole 1560, through which a fastening means, for example a screw (not shown) can be performed in the assembled state. With the help of such a screw, the telescopic rod 1500 can be frictionally connected to the rail 1000.

Furthermore, the telescopic rod 1500 has a bore 1570, which is formed on a side surface 1580 which is transverse to the further support piece 1550. A fastener, such as a screw (not shown), may be threaded into the bore 1570 to secure an end holder, which is shown in FIG.

FIG. 7 shows the profile rail 1000 of FIG. 5 with the inserted telescopic rod 1500 of FIG. 6. It can be seen that the second retaining profile 1300 continues from the first support piece 1200 via the further support piece 1550 to the second support piece 1210. In the area in which the further overlay piece 1550 and the first and second overlay pieces 1200, 1210 overlap, it is thus ensured despite the division of the holding profile 1300 on two components that can be removed that a uniform complementary holding profile 305 can be placed without problems. The telescopic rod 1500 can be moved only along the longitudinal direction 1010 of the rail 1000 due to their adapted profile. If a screw is made through the through hole 1560, which is clamped to the rail 1000 and forms a frictional connection, the telescopic rod 1500 is fixed relative to the rail 1000. Fig. 8 shows the profile rail 1000 together with the telescopic rod 1500 and the retaining strip 400 and with an end holder 1600 in a partially assembled state. As already in Fig. 7, the telescopic rod 1500 is partially inserted into the rail 1000. On the further support piece 1550, the retaining strip 400 is located. The retaining profile 305 of the retaining strip 400, which points downwards in FIG. 8 and thus is not visible, engages with the second retaining profile 1300 of the further abutment piece 1550. A mounted on the support rod 400 frame 200 would thus against Slipping in the direction transverse to the longitudinal direction 1010 of the rail 1000 are secured. The end holder 1600 has a main body 1610 and a hook 1620. The main body 1610 is attached to the telescopic pole 1500. The hook 1620 could secure a frame 200 mounted to the support bar 400 against possible lifting from the further support surface 1550.

This is shown in Fig. 9 in the fully assembled state. The frame 200 is fixedly connected to the holding piece 400 and lies with this on the support piece 1550 of the telescopic rod 1500. Furthermore, the frame 200 is held by the end holder 1600 as shown. Thus, the frame 200 is fixed with respect to the telescopic rod 1500 and also with respect to the rail 1000, d. H. he can not move relative to it anymore. This condition is desired for a mounted solar module assembly as will be described later with reference to FIG. 12.

10 shows an intermediate holder 1700 which may be used between adjacent frame assemblies 100 arranged in a row to avoid lifting of the frame assemblies 100 from respective rails. The intermediate holder 1700 has a profile piece 1710, which is adapted to the inner profile of the profile rail 1000. This means that the profile piece 1710 together with the inner profile of the rail 1000 can form a positive connection, which prevents removal of the intermediate stop 1700. The intermediate holder 1700 has, at an end 1720 opposite the profile piece 1710, a holding plate, which is connected to the profile piece 1710 via a strut 1730. The retaining plate 1720 protrudes on both sides via the strut 1730. By means of the holding plate, adjacent to the intermediate holder 1700 arranged frame 200 can be secured against lifting. This is shown in Fig. 1 1. In the mounting state shown in Fig. 1 1, the intermediate holder 1700 is located between a right side rail 230 and a left side rail 240 of the respective frame. The holding plate 1720 of the center holder 1700 rests on the side strips 230, 240 and forms with them a positive connection. Due to the positive connection, the side rails 230, 240 and thus also the respective frame are secured against lifting. Fig. 12 shows a fully assembled solar module assembly according to the third aspect of the invention. In this case, two frame assemblies 100, 101 are mounted next to each other with solar modules each contained. The frame arrangements 100, 101 are placed on two profiled rails 1000, 1001 and attached telescopic rods 1500, 1501, 1502 1503 and are secured against lifting by four end holders 1600, 1601, 1602, 1603 and two middle holders 1700, 1701. With their respective holding pieces are the frame assemblies 100, 101 on the support pieces of the rails 1000, 1001 and the other support pieces of the telescopic rods 1500, 1501, 1502, 1503. As a result of the retaining action already described with reference to the previous figures, the frame arrangements 100, 101 are thus secured against slipping down, lifting off transversely to the support surface or sliding away upwards.
