Definitions

• the present invention generally relates to hinge arrangements and more specifically the invention refers to a hinge structure for a cooking oven door adapted to be pivoted at its lower end between a first vertical position in which it closes an oven compartment and a second horizontal position in which access is offered to said oven compartment, said hinge structure being mounted in a casing secured to a housing enclosing the oven compartment, said hinge structure further comprising a link mechanism including an upper and a lower link arm each having a first end rotatably connected to the lower side of the door at spaced locations, opposite ends of the upper and lower arms being interconnected by a further link arm so as to form a hinged parallellogram link system.
• GB 758932 which describes a hinged door for a cabinet in which the door is pivotably mounted at the lower end thereof and a hinge structure operates the pivot axis to move away from an oven compartment at the same time as the door is pivoted about the same axis. Similar arrangements are shown in GB 1056631 , US 2698957 and US 2800128.
• a further object with the invention is to provide means which permit the door, in addition to the closed and open positions, to take a further position in which the door is partly open. The latter position can then be used for ventilation of the oven compartment.
• Fig. 1 shows a side view of a hinge structure according to the invention
• Fig. 2a shows a rear view of a supporting element to be fixed to the oven door
• Fig. 2b shows a top view of the supporting element of Fig. 2a with parts remote from the door omitted;
• Fig. 3 shows part of the hinge structure of Fig. 1 seen from the opposite side
• Fig. 4 shows a simplified view of the hinge structure of Fig. 1 with the door in open position.
• FIGs. 1-4 an embodiment is shown of a hinge structure intended to support a cooking oven door permitting it to move between a first vertical position in which ist closes an oven compartment and a second horizontal position in which acess is offered to said oven compartment.
• the cooking oven with its door has not been shown in the drawings and the positions of the door can be imagined by study of the positions of a support member included in the hinge structure and secured to the inside of the door.
• the hinge structure 10 is mounted in a casing 12 intended to be secured to a housing enclosing the oven compartment.
• the hinge structure comprises an elongate supporting member 14 intended to be fixedly secured to the inner side of the cooking oven door at the lower end thereof.
• the member 14 has a U-shaped section with a front wall 16 secured to the door and two side walls 18, 20 extending therefrom.
• An upper link arm 22 is rotatably mounted to the member 14 by a joint 24 and, correspondingly, a lower link arm 26 is rotatably mounted to the member 14 by a joint 28.
• the two joints 24, 28 are disposed at spaced locations along the elongate supporting member 14.
• the upper link arm 22 is rotatably connected to the lower link arm 26 by a further link arm 30 rotatably mounted to the upper link arm 22 by a joint 32 and to the lower link 26 arm by a joint 34.
• the upper link arm 22, the lower link arm 26, the supporting member 14 and the further link arm 30 form together a hinged parallellogram link system.
• the lower link arm 26 has an extension 36 the free end of which is rotatably mounted in the casing 12 by a joint 38.
• the further link arm 30 has the shape of a lever having an extension 31 which is rotatably connected to an additional link arm 42 the opposite end of which is rotatably mounted in the casing by a joint 46.
• the upper link arm 22 comprises two parallell legs 48, 50 which are joined to the member 14 so as to form an open space between the two legs 48, 50. In this open space the lower link arm 26 is allowed to move in a way unobstructed by the upper link arm 22.
• the lower ends 52, 54 of the member 14 are bent inwards to provide lateral guidance for the lower link arm 26 which has the shape of a single bar and is joined to the member 14 centrally in the space between the legs 48, 50.
• a spring arrangement 56 is provided.
• the arrangement comprises a rod 58 at one end rotatably connected to the lower link arm 26 by a joint 60.
• the rod 58 is slidably guided in a bracket 62 formed by a lug extending laterally from the casing and provided with a suitable hole.
• a helical spring 63 is disposed on the rod 58 and biased between the bracket 62 and a washer 64 disposed at the free end of the rod 62 and locked in place by a locking pin 66.
• the spring arrangement 56 also serves to provide a force acting to secure that the door in the closed position is sealingly pressed against a gasket surrounding the access opening of the oven compartment.
• a door holding mechanism 68 is provided which is effective to press the upper part of the door towards the gasket, not shown, and in addition to provide a further position for the door in which it is left partly open for ventilation purposes.
• the door holding mechanism 68 comprises a rod 70 slidingly guided in a bracket 71 and supporting a helical spring 72.
• the spring 72 is biased between the bracket 71 and a washer 74 rotatably cooperating with a trip arm 76 pivotably journalled in the casing 12 by a joint 78.
• the rotational movement of the trip arm 76 is limited by a stop 80.
• the door holding mechanism has two working positions one of which is shown in Fig. 1. In this position the spring 72 acts to press the trip arm 76 in a counter-clockwise direction assisting the spring arrangement 56 in pressing the upper part of the oven against the oven compartment sealing, the door holding mechanism also has a second operating position in which the door is left partly open. This second working position is shown in fig. 4.
• the door holding mechanism 68 is connected to the upper link arm 22 via an recess 77 provided on the trip arm.76 which cooperates with a suitable pin provided on the upper link arm 22 concentric with the joint 32.
• the hinge structure described above operates in the following way.
• the door holding mechanism only acts to define the further position of the door in which it is left partly open for ventilation purposes.
• the further movement of the door towards its fully open position involves a turning movement and an upward movement of the joint 28 to cause the outer door surface to align with the upper edge of an additional door or other panel situated below the cooking oven door.
• the link arms 22, 26, 30, 42 cooperate to effect the desired movement of the door to said open position.
• the arms 30 and 42 has got the shape indicated in Fig. 3.
• the spring arrangement 56 operates to counterbalance the door weight to make the movement easier for the user.
