Description

A structural joint and means for the use of same
The present invention concerns a connection between structural parts in a frame structure and means for using the connection. More particularly, the present invention concerns a new, simplified assembly of enclosures such as cabinets for electrical installations, etc.
The market already offers enclosures which consist of a framework clad with plates. One disadvantage of the current solutions is that there are usually a number of screw connections between the individual frame parts and between the frame and an outer plate cladding. Such enclosures usually consist of many components which, in turn, result in a correspondingly long assembly time and the associated costs. Another problem with structural screw connections is that they may be subject to prohibitively high shear forces.
FR 2770045 shows a cabinet which consists of pipes with a square cross-section and in which corner elements or 3-dimensional intersections comprise ends onto which the pipes are threaded. Locking screws can be screwed through the pipes and into the ends of the corner elements. Wall elements can be attached to the sides of the cabinet. This solution will involve a relatively short assembly time. However, the corner elements, which comprise projections along three axes, will mean high production costs whether they are cast, welded or produced in some other way. One problem with cast intersections is that they are usually moulded with a certain draught angle as part of the casting process. The draught angle will mean that the ends have a slightly conical shape, which may result in the connection with the pipe being unstable.
The present invention represents a connection between structural parts in a frame structure and a device for using the connection in which the above disadvantages can be avoided. In accordance with the present invention, structural parts are used which can be produced with simple producfion techniques, primarily extrusion and cutting. Moreover, the assembly operation can be simplified and the assembly time can be reduced to a minimum. The present invention will be described in the following using figures and examples, where:
Fig. 1a shows an enclosure in the form of a cabinet, seen from the front,
Fig. 1 b shows the same enclosure as in Fig. 1a, seen from the side,
Fig. 2 shows a section through a base frame in an enclosure, seen from above, Fig. 3 shows a section through A-A of the enclosure as indicated in Fig. 2,
Fig. 4a shows, in section, details of a side of an enclosure,
Fig. 4b shows an enlarged detail indicated in Fig. 4a,
Fig. 4c shows another enlarged detail indicated in Fig. 4a,
Fig. 5a shows an enlarged section of a corner profile of a connection indicated in Fig. 2,
Fig. 5b shows a section through a reduced version of the profile shown in Fig. 5a,
Fig. 5c shows, in perspective, the corner profile shown in Fig. 5b,
Fig. 6 shows a section of an upright profile as indicated in Fig. 2, F Fiigg.. 7 7 shows an enlarged section of a termination element shown in
Fig. 2,
Fig. 8 shows a section of an intermediate profile,
Fig. 9 shows a section of a termination element for use together with the intermediate profile shown in Fig. 8.
Figure 1a shows an enclosure in the form of a cabinet 1 , with a top 4, a base 7 and a door 2. The door may be fitted with a locking mechanism 3. As shown in Figure 1a, the cabinet also comprises side edges 5 and 6. Figure 1 b shows the cabinet from the side. A side panel 8 is indicated. The cabinet consists of a base frame and a top frame with vertical uprights connecting these two frames. The uprights are mounted in the corners of the cabinet.
Figure 2 shows a section through the base frame, seen from above. The figure includes four corner structures which are identical in this example. Therefore only one corner will be described here. The corner 20 comprises a corner profile 21 , which extends vertically according to the height of the base frame. The comer profile 21 is shown in separate Figures 5a-c, where 5a shows a corner profile in enlarged scale. Figure 5b shows a section through the corner profile in a slightly smaller scale as well as a schematic view of a fixing device in the form of a screw 24. Figure 5c shows the corner profile in perspective.
The corner also comprises an upright profile 22, which extends upwards and determines the vertical extent of the enclosure. The upright profile 22 is shown in enlarged scale in Figure 6. The corner structure also comprises a termination element 23, which forms an outer termination of the corner. The termination element 23 is shown in enlarged scale in Figure 7.
The corner structure 20 shown in Figure 2 will form a rigid connection between the frame parts which are perpendicular to each other along three axes. The corner profile 21 comprises projections 33, 34, which interact with partially closed tracks 35, 36 in the upright profile 22. This connection is locked by the fixing device 24, shown here as a threaded screw which interacts with threads in the corner profile, being forced to lock with the corner profile 22. Other fixing devices may also be used such as a wedge or equivalent which can create tension between the corner profile and the upright profile. The corner profile 21 comprises connection ends 37 and 38, which create a connection between the corner structure 20 and hollow frame elements 39 and 40, which are connected in equivalent fashion to another corner in this example. As the figure shows, the frame comprises two other frame elements 45 and 47.
The connection ends (see Figure 5a) may expediently be provided with notches 41 , 42, 43, 44 to ensure that the connection with the frame elements 39, 40 is stable. A stable connection can be created by the frame elements, which are hollow, being entered onto the ends 37 and 38, after which the frame elements are deformed so that part of their material is clamped into the notches 41 , 42, 43, 44. This connection is shown in a schematic view in Figure 3, which is a section through A-A in Figure 2. The figure shows the frame element 45 from the inside. Deformation of the frame element to lock it to the connection end of a corner profile is indicated by reference 46 (see also Figure 2). A total of four deformation points are indicated for each connection between the connection end and frame element.
Figure 3 shows a section of frame elements 40 and 47. The section shown in Figure 3 is limited vertically, as indicated by a curved cutoff line. A section of frame element 47 is shown in enlarged scale in Figure 4b. The frame elements connect the comers of the structure as described above. In addition, the frame elements are provided with means for fixing side panels 8 and fitting details (not shown). The side panel 8 may consist of two plates 51 , 52, which are bent at the edges and arranged inside one another. The outer plate 51 may have a lower end in the form of a lip 53, which rests in the notch 48 in the frame element 47. The means 49 and 50 for fixing a fitting comprise traditional, partially closed tracks in which, for example, it is possible to thread fixing devices with a T-shaped head (not shown).
Figure 4a shows several details on one side of an enclosure. As shown above, the side comprises a side panel 8 consisting of an outer plate 51 and an inner plate 52, as well as a frame element 47. At the top, the side comprises another frame element 54, see also Figure 4c. The frame element 54 may comprise means 56 and 57 for fixing a fitting, as described above. As Figure 4a shows, the side panel may be fixed to the frame element 54 by means of a fixing device 55 such as a screw connection. Other types of fixing such as riveting, gluing or welding may also be used.
The corner connection 20 shown in Figure 2 also comprises a termination element 23, which will be described in further detail with reference to Figures 2 and 7. The termination element comprises an outer, curved surface 70 which forms a tight seal between the side panels adjacent to the corner. Figure 2 only shows one side panel 8 adjacent to the corner structure 20. The other has been removed to show other details. The termination element runs primarily along the full vertical length of the enclosure between its top and base. As shown in Figure 7, the termination element 23 comprises two projections 71 , 72, which are provided with beads 73, 74 at their ends. The projections and beads interact with the projections 75, 76 in the upright profile 22 (Figure 6) in such a way that the termination element can easily be pressed into place to lock with the upright profile when assembling the enclosure. As shown in Figure 2, the termination element 23 has a projection which runs in over the edge of the side panel 8 and forms a tight connection with it.
In the above description, the aim was to describe the base frame of the structure and the vertical construction of the structure. However, the structure also comprises a top frame (not shown) which, in principle, has the same structure as the base frame.
If enclosures of large dimensions are to be built, it is possible to use an intermediate upright profile 87, as shown in Figure 8. The intermediate upright profile has the same function as the previous upright profile and extends primarily along the full vertical length of the enclosure, but allows a level connection to be made between two adjacent side panels. The figure shows a section of the intermediate upright profile, seen from above, in which partially closed tracks 35' and 36' interact with the projections 33 and 34 of a corner profile 21 in the same way as described in connection with the upright profile 22. In addition, the intermediate upright profile comprises other partially closed tracks 35" and 36", which interact with another corner profile which is equivalent to the corner profile shown earlier and provided with projections which interact with the tracks.
Figure 9 shows a section of a termination element 80 with projections 81 , 82, which have beads 83, 84. The projections and beads interact with the projections 85 and 86 in the intermediate upright profile (see Figure 8). In the same way as described for the termination element 23, the termination element extends so that it runs in over the ends of adjacent side panels (not shown). Using the intermediate upright profile described above, it will be possible to build enclosures of different shapes and sizes.
All the structural elements in the enclosure such as the corner profile, upright profile, intermediate upright profile, side panel with inner and outer plates, frame elements, termination element, top cover and any base plate may be made of aluminium or an aluminium alloy. All profiled elements may expediently be made by extruding aluminium and subsequently cutting them to length. The outer, visible surfaces of the enclosure may be finished in accordance with prior art techniques.
An enclosure with four corners may be assembled as follows: The corner profiles 21 are combined with the frame elements 39, 40, 45, 47. A press bench with a hydraulic tool may be used to deform the frame parts where they are to be locked to the corner profiles. In this way, four corners may be connected to form a top or base frame. Upright profiles are threaded into the base frame and locked by means of fixing devices. The top frame may then be threaded down onto the upright profiles and locked in place in the same way as the base frame.
The side panels may, for example, be made of 2 and 3 mm aluminium plates. The inner plate may remain unfinished/chromated in order to maintain good contact with the upright/frame (among other things, to prevent electromagnetic interference with internal components). The side panels are fitted by being inserted down into the notch in the frame parts in the base frame and then being fixed at the top. The termination elements can then be fitted. The top or cover is put on last and extends down against the upper part of the side panels so that the fixing devices here are covered.
