Swinging and locking device, particularly for vapour escape hoods at kitchen ranges

Abstract

Abstract A pivoting device suitable for pivotably mounting a pivotable vapor hood to a fixed housing above a cooking range, in a manner permitting the pivotable hood to be manually adjusted angularly to any desired forward and backward position, while permitting easy removal and replacement of the pivotable hood for cleaning purposes. A pair of such pivoting devices are preferably fixed to opposite interior surfaces of the fixed housing, and each device is provided with an inwardly-extending sleeve for insertion into corresponding holes in opposite flexible end areas of the pivotable hood, to support the hood for rotation. An arrangement of locking tabs on the pivotable hood detachably engages locking means on a pair of flexible follower arms extending from the pivoting devices. Each pivoting device contains a coil spring acting on its corresponding follower arm to urge the pivotable hood upward and backward, and each pivoting device is provided with a screwadjustable friction disk tending, with the aid of the action of said spring, to clamp each follower arm in the angular position to which it is manually moved while permitting its easy motion between such desired positions. This invention relates to a swinging and locking device of the kind suitable for use in providing an over-range vapour hood which is forwardly and backwardly pivotable. The aforesaid vapour escape hoods are adapted for movement between two end positions, viz. one position in which the hood is swung inwards and the space above the cooking plate is accessible at maximum, and a second position in which the hood is swung outwards and said space is enclosed in the upper section by the hood for collecting vapour from cooking and frying. In addition to its movability, the hood is desired to be detachable for cleaning it throughout from time to time. In the conventional swinging and locking devices it is necessary for this purpose to unscrew screw connections and to loosen other details. This renders it so tedious and complicated to attach and remove the hood, that housewives in general do not carry out these operations. Heretofore, the kind of movement of the hood permitted in relation to the stationary structure, has also not been satisfactory. It is the primary object of this invention to overcome the aforesaid disadvantages and to bring about in general a further development and improvement of the state of art concerned. This object is achieved by the device according to the invention. Any housewife should be able to remove and attach the hood using the swinging and locking device of the invention without any difficulty. Even when the hood is detached and removed frequently, the parts will not loosen and give rise to rattling noises and the like. The construction according to the invention, furthermore, requires substantially no maintenance.
