Description

(1) With the intention of better showing the characteristics of the invention, a few preferred embodiments of a canopy for a compressor or generator installation according to the invention comprising a number of lateral beams onto which the at least one roof panel of the canopy is mounted, are described hereinafter by way of example, without any limiting nature, with reference to the accompanying drawings, wherein:

(2) FIG. 1 shows an exploded view of a conventional canopy for a compressor or generator installation;

(3) FIG. 2 shows a canopy for a compressor or generator installation according to the invention;

(4) FIG. 3 shows more in detail the part that has been indicated by F3 in FIG. 2;

(5) FIG. 4 shows more in detail the part that has been indicated by F4 in FIG. 2;

(6) FIG. 5 shows more in detail the part that has been indicated by F5 in FIG. 2;

(7) FIG. 6 shows more in detail the mounting of a door and a roof panel of the canopy according to the invention;

(8) FIG. 7 shows the lock mechanism of a door of the canopy according to the invention.

(9) The conventional canopy 1 in FIG. 1 comprises a chassis 2 with a base plate 3 comprising a body with a mounting surface bounded by a rectangular peripheral edge 4; and a mounting frame 5 containing this base plate 3 and going around the rectangular peripheral edge 4,
whereby each corner of the rectangular peripheral edge 4 is provided with a corner stay 6 and whereby intermediate stays 7 are provided at the rectangular peripheral edge 4 in between the corners of the rectangular peripheral edge 4.

(10) The corner stays 6 and the intermediate stays 7 are directly mounted on the base plate 3 of the chassis 2 and all extend in a same direction perpendicular to the mounting surface of the base plate 3 and outwards from the body of the base plate 3.

(11) Doors 8 are hinged on the corner stays 6 and the intermediate stays 7.

(12) Roof panels 9 are mounted onto free ends of the corner stays 6 and the intermediate stays 7. By free end is meant an end of the stay which is opposite to the end of the stay which is mounted onto the mounting surface of the base plate 3 and which is not mounted to the mounting surface of the base plate 3.

(13) FIG. 2 shows a canopy 1 according to the invention which differs from the conventional canopy 1 of FIG. 1, for example in the fact that no intermediate stays 7 are present and that the free ends of the corner stays 6 are connected by means of lateral beams 10.

(14) In this case, at each one corner of the rectangular peripheral edge 4 of the mounting surface of the base plane 3, the free end of each corner stay 6 is connected to the free end of the corner stays 6 at both corners adjacent to this one corner.

(15) In order to support the roof panels 9, in fact, only the two lateral beams 10 that are connecting the corner stays 6 at corners A and B respectively C and D are strictly necessary to support the roof panels 9. The two lateral beams 10 connecting the corner stays 6 at corners A and D respectively B and C may be included in the canopy 1 to increase the perpendicular alignment of the corner stays 6 with respect to the mounting surface of the base plate 3 and the mechanical stability and stiffness of the canopy 1, but this is not a necessary requirement of the invention.

(16) It is not to be excluded that the peripheral edge 4 of the mounting surface of the base plate 3 has another polygonal shape instead of being rectangular, for example an L-shape.

(17) FIG. 3 shows in more detail the mounting of one of the corner stays 6 onto the chassis 2 of the canopy 1. The base plate 3 is at each corner of its peripheral edge 4 provided with a mounting hole 11 which is configured to contain a mounting end of the corner stay 6.

(18) The corner stay 6 may be detachably mounted with its mounting end onto the mounting frame 5 of the chassis 2. This detachable mounting may be established by means of a bolt connection 12 comprising a minimum number of bolts 13, in this case only two.

(19) FIG. 4 shows in more detail the mounting of lateral beams 10 onto the free end of one of the corner stays 6 of the canopy 1. The corner stay 6 is configured such that the lateral beams 10 snap in this corner stay 6, for example, by means of a groove 14 in the lateral beam 10.

(20) Preferably, the lateral beam 10 may be fastened to the corner stay 6, for example, by means of a click connection, a glue connection, a rivet connection, etc. More preferably, the lateral beams 10 may be detachably attached to the corner stay 6, for example, by means of a bolt 15, as indicated in FIG. 5.

(21) FIG. 6 shows in more detail the mounting of a door 8 and a roof panel 9 onto the lateral beams 10 of the canopy 1. The door 8 is hung on one of the lateral beams 10 by means of at least two knobs 16 which protrude at a same edge on a side of the door 8 whose edges in a hung state of the door 8 are tangent to an internal space contained by the canopy 1. By this internal space is meant a polyhedral space that is bounded by the base plate 3, the corner stays 6, and the lateral beams 10. The knobs 16 are configured such that the door 8 is hung onto this lateral beam 10 by means of these knobs 16, at the edge of the door 8 at which these knobs 16 are provided.

(22) The roof panel 9 is mounted onto the lateral beams 10 and comprises at least two recesses 17 containing the knobs 16 of the door 8, at least one recess 17 for each knob 16.

(23) The door 8 may be detached from the lateral beam 10 and the canopy 1 by lifting the door 8 with the knobs 16 from the recesses 17 and then moving the edge of the door 8 which is provided with the knobs 16 away from the canopy 1.

(24) Doors 8 may be placed sequentially next to each other, hung onto the lateral beams 10, to close off the lateral sides of the canopy 1. By lateral sides is meant the sides of the canopy 1 which two-by-two share one of the corner stays 6 as a common edge.

(25) An additional lateral beam 10, which is not necessarily needed to support the roof panels 9, may be specifically incorporated into the canopy 1 to provide a lateral side of the canopy 1 at a desired and/or required position with one or more doors 8, which are then hung onto this additional lateral beam 10.

(26) FIG. 7 shows in more detail a lock mechanism 18 of the door 8 which is provided at an edge of the door 8 which is opposite to the edge at which the door 8 is hung onto the lateral beam 10.

(27) It is not excluded that the door 8 can be hooked onto the chassis 2 by means of a mortise and tenon connection, whereby the door 8 or the chassis 2 comprises a protruding tenon which corresponds to a mortise in the chassis 2 respectively the door 8, and can be locked onto one of the lateral beams 10 by means of the lock mechanism 18. In other words, the position of the lock mechanism 18 and the knobs 16 respectively the mortise and tenon connection may be interchanged on the door 8.

(28) The present invention is by no means limited to the embodiments described as an example and shown in the drawings, but a canopy for a compressor or generator installation according to the invention and a compressor or generator installation provided with such canopy can be realised in all kinds of forms or dimensions without departing from the scope of the invention.
