Abstract
A box comprising a box bottom part and a lid part which is pivotably supported relative thereto by means of a hinge device between an open and a closed position is particularly suited for use in the Ex area. The hinge device comprises a lower hinge part assigned to the box bottom part and an upper hinge part assigned to the lid part, which are pivotably connected to each other. To provide a permanent connection between lid part and box bottom part in a simple way and at low costs, while simultaneously said parts are pivotable relative to each other in a safe way, one hinge part is slidably supported and the other hinge part is arranged to be at least partly screw-mountable in the respectively assigned box bottom part and lid part, respectively.
Claims14
A box (1), particularly for use in the Ex area, comprising a box bottom part (2) and a lid part (4) which is pivotably supported relative thereto by means of a hinge device (3) between an open and a closed position, the hinge device (3) comprising a lower hinge part (6, 7) assigned to the box bottom part (2) and an upper hinge part (6, 7) assigned to the lid part, which are pivotably connected to each other, characterized in that one hinge part (6, 7) is slidably supported and the other hinge part (7, 6) is arranged to be at least partly screw-mountable in the respectively assigned box bottom part (2) and lid part (4), respectively.
The box according to any one of the preceding claims, wherein the rim flange (10) has an oval, cornered or other non-circular cross-section which substantially corresponds to a cross section of a rim flange recess (13) in the box bottom part (2).
The box according to any one of the preceding claims, wherein the rim flange recess (13) is formed on one end (14) of a displacement bolt bore (15) in an edge portion (16) of the box bottom part (2).
The box according to any one of the preceding claims, wherein a pivot range (17) from the upper hinge part (7) to the lower hinge part (6) is greater than 90°, preferably about 180°, and particularly preferably up to 220°.
The box according to any one of the preceding claims, wherein the upper hinge part (7) comprises a screw-in bolt (18) at least on its screw-in section (20) opposite to the pivot end section (19) which is pivotably connected to the lower hinge part (6).
The box according to any one of the preceding claims, wherein the bearing end (11) comprises two bearing projections (22) spaced apart from each other by a bearing gap (21), between which a bearing shaft (23) is arranged for pivoting the upper hinge part (7).
The box according to any one of the preceding claims, wherein a diameter (24) of the upper hinge part (7) is smaller or not more than a diameter (25) of the lower hinge part (6).
The box according to any one of the preceding claims, wherein the upper hinge part (7) comprises a middle, substantially cylindrical, mid-section (26) from which the screw-in end section (20) as a screw-in bolt (18) provided with external thread (18) as well as the pivot section (19) are projecting.
The box according to any one of the preceding claims, wherein the upper hinge part (7) is substantially configured as a screw-in bolt (18) with pivot end section (19).
The box according to any one of the preceding claims, wherein a screw-in stop (27) is formed between mid-section (26) and screw-in bolt (18).
The box according to any one of the preceding claims, wherein the hinge device (3) is substantially arranged on two box corners (28).
The hinge device (3) according to any one of the preceding claims, comprising a lower and upper hinge part (6, 7) which are pivotably connected to each other, wherein one hinge part (6, 7) is configured to be slidable and the other hinge part (7, 6) to be at least partly screw-mountable.
