Abstract: A simple cord locking device which may also be used for ribbons comprising a sleeve and a slide moveable therein. The latter is manufactured from a rigid plastic material and comprises a head, a body, in which an opening and at least a groove are formed, and a spring formed integral with the body. Within a prismatic outer contour the spring is formed as a web of material extending in zig-zag. The sleeve is formed as a planar box, open at one short side thereof and having openings formed in the long sides thereof.

Abstract: An operator for keeping doors, windows, shutters, or preferably entrance doors in a closed position has operating elements housed within a casing attached to a bar. A rod, for instance an espagnolette rod, is operatively connected to the operating elements and arranged for maneuvering at least one bolt.The operating elements include means for maneuvering a further bolt. A handle is arranged for rotation in opposite direction from a neutral position. In one direction in the first bolt is manoeuvred, and in the other direction the further bolt is manoeuvred.The operator has a spring device for returning the first bolt to a retracted position as soon as the handle returns from the position thereof corresponding to an extended bolt, unless the return movement of the bolt is positively prevented, for instance by friction engagement with the striker plate.

Abstract: A device for keeping a door, a window, a shutter, etc., in a closed position. The device comprises operating elements housed in a casing attachable to a bar. The operating elements are connected to an element maneuvering at least one bolt.A lock part of the device is formed as an insert of a predetermined dimension having a lock of an optional lock type therein and arranged for being inserted directly into the housing within a space of a corresponding dimension.

Abstract: A strap buckle comprises a generally planar housing in which at least three bars extend in parallel relationship between opposite side walls for the retention of a strap end. A first strap passage extends substantially parallel to the plane of the housing and is defined, at one side by at least one of the bars, while the other side of the passage is defined by two further ones of said bars having a second strap passage therebetween.The strap end can pass through the first strap passage, around one of the two further bars, inwardly through the second strap passage, and out through a portion of the first strap passage, between the incoming part of the strap and the other of the two further bars.

Abstract: An implement suited for cleaning also interproximal faces at the molars is made of pliable material, and includes a middle portion and two tapering end portions issuing therefrom. The middle portion is formed with a cross section to make it substantially rigid in use, and the end portions are bent in the same direction with respect to the middle portion.The end portions have a triangular cross section adjacent to the middle portion and taper towards the distal ends, where the end portions are very slim compared with the cross section adjacent to the middle portion. At least the side face of the each end portion turned inwards at the bend is roughened.

Abstract: A buckle includes an open rectangular frame having a passage lying in the plane of the frame, together with a locking washer slidably disposed in the passage. Means are provided, in the form of complemental construction on the frame and washer, preventing the locking washer from falling out of the frame at least in one direction. One strap end can be secured to one transverse portion of the frame, while another strap end can be directed through the opening in the frame, around one side of the locking washer, and back through the same opening. The other side of the locking washer can extend through the other side of the frame.
