Abstract: A device for coupling two outer parts (3) to a third part (2) disposed therebetween. The device includes a plurality of fasteners 7 each threadably mounted to an opening (9) in one of the outer parts and a cylindrical recess (6a) in the third part. Each fastener 7 has a conical head 7a that rests against the opening in the outer part.

Abstract: An adjustable friction hinge assembly for use on the lid or cover of a record player is made of plastic material. The hinge has anti-squeak properties to prevent squeaking when the lid or cover is raised. The hinge also has the capability of holding the lid, when raised, in the raised position without falling down. The knuckles of the hinge and the adjustment pin are made of a first plastic material having elastic properties, preferably acetal, while a washer of a different plastic material, preferably nylon, is placed between the facing end surfaces of the movable knuckles. The two different plastics are so selected that, when the two materials are in frictional engagement with each other, the coefficients of static and dynamic friction are similar. This avoids squeaking. The plastic adjustment pin passes through one end knuckle having an internal shoulder and screws into the other end knuckle. The head of the pivot pin abuts against the internal shoulder.

Abstract: A door closing apparatus is described which embraces a unit for generating a closing force, a lever attached thereto via a releasable clutch for actuating the door and a controllable blocking device. The releasable clutch consists of a threaded connection which permits relative rotation between the actuating lever and the drive axle over a predetermined stroke. An abutment for frictionally locking the actuating lever is provided, with the frictional locking abutment becoming effective relative to the actuating lever at at least one end of the stroke. The holding force which sets in between the actuating lever and the frictional locking abutment is smaller than the holding force of the blocking device which blocks the unit for generating the closing force in the closing direction.
