Definitions

• the invention relates to a switchgear cabinet with a frame composed of frames Ln, hmengest e LL, the sides of which can be partially closed with door elements, the door elements being hinged, fixed and releasable in the frame by means of hinge elements and locking elements on adjacent vertical frames .
• the known scarf tendrils of this type usually have only one door element that closes the open front of the frame, while the other sides of the frame are closed with wall elements. It is already difficult for the door element to strike the vertical frame legs of the frame if the door element is to be hinged to the left frame leg and the other to the right frame leg of the frame. Therefore, the articulation of the articulation side of the door element and the fixing of the closing side of the door element to the frame are carried out by means of separate Hinge and locking elements that must be attached to the vertical frame legs, depending on the type of stop. If the type of attachment is to be changed, then considerable assembly and opening is required, since all hinge and locking elements on the frame have to be exchanged. In addition, considerable assembly effort is required if a wall element is to be replaced by a door element.
• At least all vertical frame legs of the frame symmetrically to the center of their longitudinal abs measure at least two Ans ch elements which can be used both as a hinge element and as a closure element, and that the door elements on their insides symmetrically have hinge elements for hinge bolts that can be aligned with the connection elements of a frame leg on the articulation side and counter elements that can be aligned with the connection elements of an adjacent frame leg on the closing side.
• connection elements of the frame can be used as a hinge and closing element. In the simplest case, this is ensured in that the connecting elements on the vertical frame legs of the frame are configured as vertically oriented sleeves. Since the connection elements are attached to all vertical frame legs, the frame can be closed at the front and rear with a door element. It is also possible, by appropriate attachment of the connection elements to the frame legs, to optionally lock both sides of the frame with a door element.
• a simple articulation of a door element on the frame is achieved according to one embodiment in that the hinge elements on the door elements are designed as double sleeves, the receptacles for hinge bolts corresponding to the receptacles of the sleeves of the frame gesture serving as connecting elements and receiving a connecting element of a frame leg .
• the connecting elements of the frame and the subsequent aligned hinge elements of the door element bi lden recordings for hinge bolts, which are then only to be inserted.
• the fixing of the door element in its closed position is simply achieved in that the opposing elements are formed as locking bolts, which are guided in sleeves fixed to the door elements and can be inserted into and out of the connecting elements of the frame serving as locking elements can be brought out again.
• the closing and opening of the door element is facilitated in that the counter-locking elements formed as locking bolts are parts of push rods of a push rod lock and are adjustable in opposite directions by means of a push rod lock. With the push rod lock, the fixing of the door element in the closed position can be secured.
• Counter-locking elements of the door elements each connect to the mutually facing sides of the connecting elements of the vertical frame legs, then the type of stop of the door element is particularly easy to change.
• the outer corners of the frame legs are formed by means of inclined professional leak sections which are at an obtuse angle to the abutting sides of the volume and that the connecting elements on these inclined profi ec kabs c hni tt en the frame legs are attached, then one or the other of the abutting sides of the frame can optionally be closed on a frame leg of the frame with a door element.
• the type of stroke can be chosen arbitrarily.
• the design is preferably such that the professional leak sections of the frame legs are at an angle of 135 ° to the two preferably perpendicular outside professional sections of the frame legs, which are preferably designed as open or closed heights Lp rof i l abs c hn i 11 e.
• the professional leak sections of the frame legs by means of transition sections in the Overside professional sections, which are preferably perpendicular to the outside sections and thus form a receptacle for the connection elements, then there is sufficient space in the outer corner areas of the control cabinet for the pivoting of the door element.
• a clean transition can be achieved in the corner areas of the scraper tendril in that the connecting elements fastened in the receptacles of the frame legs are flush with the outside sections of the frame legs, and that the door elements are provided with a right-angled edge and that the hinge elements and the counter-locking elements of the door elements are arranged in the corner regions delimited by the door element itself and the folded edges.

• FIG. 2 is a perspective partial view of area II of FIG. 1,
• Fig. 4 shows the view on the inside of a door element with hinge elements and opposing elements.
• the frame 10 according to FIG. 1 is composed of the frames 11 to 22, preferably profiles having the same cross section being used.
• An open and closed hollow profile can be selected.
• Preferably inward facing professional sides are provided with rows of fastening receptacles, not shown, in order to be able to install internals in the frame 10.
• the frame legs 11, 14, 15 and 19 can be connected to form an inseparable frame.
• These two frames are detachably connected to one another via the frame legs 16, 18, 20 and 22.
• the two frames can also be formed from the respective four lateral frame legs 11, 12, 16 and 20 or 13, 14, .18 and 22.
• the frame legs 15, 17, 19 and 21 then form connecting struts.
• the upper and lower four frames c hen ke 15, 16, 17 and 18 or 19, 20, 21 and 22 can be connected to fixed frames, so that the four vertical frame legs 11, 12, 13 and 14 the Connect the two frames.
• connection elements 30 are attached at the same distance a from the ends, as the partial view according to FIG. 2 shows. These connection elements 30 are formed as vertically aligned sleeves and are mounted symmetrically to the center M of the vertical frame legs 11, 12, 13 and 14.
• the frame handles 11 to 22 are designed as open hollow professional sections, as can be seen in FIG. 3.
• the outer ends of the frame 10 are chamfered, as the professional leak section 46 of the frame leg 13 shows.
• This Prof ilec kabs chni tt 46 merges with transition sections 45 and 47 into the outer side sections 43 and 44, which are preferably at right angles to one another and define the outer sides of the frame 10.
• the outer sides of the runners 43 and 44 are bent at right angles at the ends, as shown in sections 48 and 50 and 49 and 51 respectively.
• the frame legs are formed on the corner outer edges of receptacles in which the connecting elements 30, formed as sleeves, can be fastened flush with the outer sides of the frame frame 10.
• the door element 40 is provided with edges 41 bent at right angles.
• hinge elements 42 embodied as double sleeves are fastened on the articulation side of the door element 40 in such a way that these double sleeves accommodate connecting elements 30 of a frame frame. Since these double sleeves have the same receptacle as the connection elements 30 of the frame leg, the door element 40 can be attached to the frame frame 10 with the aid of scraper bolts. Since the double sleeves of the door element 40 serving as hinge elements 42 are also attached symmetrically to the horizontal central plane, the door element 40 can be hinged left and right in the two positions rotated by 180 °, as can be seen in FIG. 4.
• a swift pleasant connection is arranged between the edge 41 and a reinforcement and mounting frame 55 mounted on the door side.
• the two oppositely adjustable push rods form counter-locking elements 61 and 62 and are controlled by a push rod lock 60.
• the push rods are guided in sleeves 63, which are arranged so that the ends of the sleeves 63 led out into the socket elements serving as locking elements 30 of a frame leg can be inserted and removed again. Since the push-lock connection is formed symmetrically to the horizontal center of the door element 40, the door element 40 can be struck in two positions rotated by 180 ° on a left or a right of two adjacent vertical frame legs of the frame, the respective ls other frame legs cooperate with the closing side of the door element 40.
• the hinge elements 42 formed as double sleeves are arranged so that the distance a to the receptacle for a connecting element 30 serving as a hinge element of the frame 10 with the distance a of the connecting elements 30 after Fig. 2 matches. Then the hinge part 42 of the door element 40, formed as a double sleeve, can accommodate the connecting element 30 of the frame 10 between the two sleeves.
