  • connection blocks are described in the second aspect of the invention.
  • meaningful frameworks are described in the third aspect of the invention.
  • the method according to the first aspect of the invention allows easy mounting of frames that accommodate photovoltaic modules or collector modules.
  • the applicability of the method is not limited to the scope of such modules.
  • the two connecting blocks are inserted through the longitudinal grooves of the two rails and provide, in a preferred embodiment, for example, after a rotation of 90 °, a positive connection with the respective rails ago. An unintentional removal of the connecting block from the rail is thus prevented. In the mentioned embodiment, a removal requires a new rotation by 90 °.
  • the connecting blocks are moved along the longitudinal groove of the respective rail to push the pins of the connecting blocks in the space provided for recesses of the frame.
  • the frame is already positively connected to the connecting blocks, which in turn are positively connected to the rails.
  • the frame is held on the rails.
  • the method has in addition to the particular simplicity described the advantage that it can be carried out in preferred embodiments with a plurality of frames in succession, that each two adjacent frames are spaced by two intermediate connecting blocks and thus that each frame by four mandrels, each to a owned by the four adjacent connecting stones.
  • end holder can be mounted such that on the frame a force along the profile rails is exercised.
  • both the frame and the connecting blocks located between the frames are held in position along the longitudinal grooves.
  • the end holders are preferably screwed to the profiled rails, so that they are prevented from slipping along the profiled rails by adhesion.
  • connection stones are needed for mounting frame rows, whereby the amount of required assembly material is very small.
  • the operations described with the connecting blocks are carried out quickly, without tools and without significant effort. It should be noted that it is possible to deviate from the above-mentioned order of the method.
  • the second frame can be arranged on the profile rails before the connecting blocks are inserted into the longitudinal grooves of the profile rails.
  • only one connecting block can be inserted into a longitudinal groove before the second frame is placed on top.
  • the method according to the first aspect of the invention is repeated in a corresponding manner until a desired plurality of frames are mounted side by side. Typically, seven to fifteen, more preferably eleven, juxtaposed frames are mounted. Thereafter, at least one end holder and an expansion joint are mounted. While the end holder is designed to secure the modules, as described above, against slipping in the direction of the rails, the expansion shock compensates for changes in length, which occur due to temperature fluctuations.
  • the end holder can be fastened, for example, in a conventional manner by screwing to the profile rails. It has been found that due to the thermal expansion properties of aluminum when using this material, the arrangement of an expansion shock after seven to fifteen and especially eleven modules is particularly advantageous.
  • Aluminum is advantageous because of its ease of processing, its low weight and its corrosion resistance.
  • horizontal ie parallel to the mounting surface mounted rails used on which the frames are mounted adjacent to each other.

  • an electrical interconnection of photovoltaic modules accommodated in the frame is advantageous due to the electrical properties of the photovoltaic modules and the inverters.
  • a second aspect of the invention relates to a connector block for mounting two adjacent frames of photovoltaic modules or collector modules on a mounting rail, the connector block comprising: a main body, two mandrels protruding from two oppositely facing surfaces of the main body; each one in one of the adjacent frame is inserted, and a projecting from the main body crosspiece with an adapted to a profile of the rail counter profile for producing a space-locking connection with the rail.
  • Frames which can be fixed with the connection block according to the second aspect of the invention are described in the third aspect of the invention.
  • the main body of the connecting block is preferably designed cuboid. This allows two-dimensional contact with the two adjacent frames.
  • the main body can also be cylindrical or in another form, which allows the attachment of both the two mandrels as well as the crosspiece.
  • the mandrels may also point in directions that are not on a straight line, which, for example, can produce an additional jamming holding effect after the mandrels have been inserted into recesses of adjacent frames.
  • the protruding from the main body crosspiece is used to make a positive connection with the rail.
  • it has a counter profile, which is adapted to the profile of the rail.
  • the crosspiece is preferred by the thorns spacedly attached to the main body so that the main body with the part to which the mandrels are attached can protrude out of the rail while being within the rail with the part to which the cross-piece is attached.

  • the main body and the cross-piece together when considered in a T-shape.
  • the crossbar of the T is the crosspiece which contains the counter profile.
  • the T-shape allows a positive connection with the rail to be made on two sides of the main body. As a result, a better, in particular better against blurring stiffened connection between the connecting block and the rail is possible.
  • the crosspiece has two free legs, each wedge-shaped and attached to opposite-facing surfaces of the main body.
  • the wedge tapers, as viewed in the longitudinal direction of the main body, with increasing distance from the longitudinal end of the main body.
  • the wedge shape has the advantage that it forms a simple and universally fitting counter-profile.
  • the crosspiece of the connecting stone is designed such that it can be inserted into an opening of the profile of the rail and produces by subsequent rotation by about 90 ° with the profile of the rail a positive connection.
  • This allows a particularly simple attachment of the connecting block to the rail.
  • the insertion of the connecting blocks is possible at any point of the rail, ie it is not necessary to introduce the connecting blocks at the ends of the rail.
  • the crosspiece is aligned so that it fits with its largest extent through the mentioned opening of the profile. After the crosspiece has been inserted through the opening, it can be engaged with the rail by a mere 90 ° turn. However, a displacement of the connecting block along the rail is still possible because the rail has a constant cross-section in this direction.
  • connection stone which already has a mandrel in a frame, can be moved away from the frame to release the frame. This may be necessary, for example, if the frame needs to be replaced with its photovoltaic modules or collector modules or if they need to be serviced.
  • connection stone can also be removed again from the rail, without having to be pushed to the end of the rail.
  • Individual connection blocks can thus also be removed or replaced without having to disassemble a plurality of adjacent frames and associated fasteners.
  • the crosspiece projects in two opposite directions from the main body, which are transverse to a longitudinal direction of the mandrels. If the crosspiece is inserted into the opening of the rail, the mandrels are initially transverse to the rail and are therefore not yet suitable to be inserted in recesses of adjacent frame, which rest on the rail. As already explained, however, the connection block can be rotated by 90 ° so that the crosspiece produces a positive connection with the profile rail. Since the mandrels are also rotated by 90 °, they are after the rotation substantially parallel to the rail. Thus, they are then also suitably aligned to be inserted into corresponding recesses of resting on the rail adjacent frame.
  • the connecting block is integrally formed, which allows a simple production, for example by injection molding, as well as a high strength of the connecting block.
  • connection block may also be formed in several pieces, e.g. the main body, the mandrels and the crosspiece are each made individually and are connected by screwing, welding, gluing or other connection techniques with the connection stone.
  • the two pins in their longitudinal section near the main body each have an electrically conductive contact area.
  • the contact area is suitable for producing an electrically conductive contact between the connection block and a frame into which the connection block can be inserted.
  • Such a contact region is preferably an electrically conductive piece of the mandrel whose diameter is chosen to fit the recess in the frame, so that it can come into contact with an inner surface of the recess when inserted into the recess.
  • the recess has the shape of a slot, the exact fitting of the mandrels across the longitudinal direction of the oblong hole is sufficient.
  • a third aspect relates to a frame for accommodating one or more photovoltaic modules or collector modules with two frame elements on opposite-pointing outer sides of the frame, which each have at least two outlets.

  • the connecting blocks can for example also be inserted into the rail and inserted into the frame, if they are already on the rails.
  • the frames are then pushed together piece by piece, whenever a new pair of connection blocks has been inserted into the two profile rails.
  • various other variants of the mounting sequence are possible, which selects the person skilled in the art according to the example of the above description for its respective mounting situation.
  • the arrangement of the two frames 200 and 200 'thus produced on two profiled rails 300 and 300a is shown in FIG.
  • the rails 300 and 300a are parallel to each other and to the ground (not shown), but at different distances from the ground.
  • a bolted end holder (not shown) and an expansion joint (both not shown) can be mounted.
  • the screw connection thus serves as a safeguard against undesired lateral slippage when strong forces act (storm, etc.) and can also be provided with an anti-theft device.
  • the expansion shock serves to compensate thermally induced changes in length.
  • the module field 400 has two profiled rails 300a, 300b, on which frames 200a, 200b, 200c, 200d, 200e are mounted. In the frames 200a, 200b, 200c, 200d, 200e, photovoltaic modules 500a, 500b, 500c, 500d, 500e are mounted.
  • Typical module fields not only consist of a juxtaposition of frames with respective photovoltaic modules or collector modules, but also of an arrangement of several pairs of profile rails with respective frames one behind the other. In principle, arbitrarily large areas can be used to generate electricity or to heat a fluid.
  • each case 22 modules are electrically interconnected in order to achieve a good adaptation of the performance of the solar modules to common inverters.
  • a different number of interconnections may prove most suitable.
  • the module array 400 according to the fifth aspect of the invention not only offers the advantage of a particularly simple assembly with low material usage, but also allows easy replacement of the frame 200a, 200b, 200c, 200d, 200e or the connecting blocks lying between these frames.
