Abstract: The present invention relates to a clasp for the connecting of two parts comprising a first (1) and a second (2) clasp part consisting of, against the first part (1) fixed, and from this extending part (3), in the second part (2) an opening (3) the shape of which closely connects to the outer shape of the extending part (3) so that the second part (2) can pass over the latter as well as the means, to restrain the second part on the extending part (3), in the spring-loaded means (8, 10, 11) and an edge or groove (5) arranged inside the second part's opening. The clasp consists of spring-loaded means (6, 7) designed to move the parts away from each other upon the parts being released. A button (4) arranged in the cylinder is placed for activation when the clasp's parts are to be released from each other.

Abstract: This invention is a Standing board for prams, which is fastened to a pram with fastening beams that protrude from the Standing board and that have means for fastening to the pram on their outer ends. The fastening beams (4, 5) point forward in the Standing board's normal direction of movement and are basically parallel with it. They are also adjustable in a right angle to the movement direction, mounted on the forward edge of the Standing board with their fastenings (8, 9), which have means for retaining the fastenings in their adjusted position on the Standing board (1). The fastening beams are mounted in a manner that allows them to be twisted in the fastenings for adjustment of their angle relative to the supporting area.

Abstract: A standing board for connection to buggies, prams, etc., comprising a board (1), wheels (2) and means for connecting the board (1) to buggies/prams, comprising two arms (3), which are directed diagonally forwards in the normal direction of travel of the standing board. The mounting arms (3) are connected to the board (1) and can be moved mainly horizontally, perpendicularly to the direction of travel of the standing board.

Abstract: A locking device for a safety gate which includes a gate surface made from material which may be wound up with a mechanism for prevention of unintentional unwinding of gate material, the mechanism including a catch wheel which co-rotates with the unwinding, a rotatable catch for cooperation with the cogs of the catch wheel and a release mechanism releasing the gate for unwinding. The mechanism also includes a driver which is arranged adjacent the catch wheel and may be rotated concentrically therewith, at which rotation a pin which is arranged at the catch is displaced in a slot in the driver so that the pin, when the catch is in a released position, contacts a surface inside or adjacent the slot. The driver includes a fork with two shanks between which the slot is arranged. The slot is L-shaped. In order to release the gate, a manually performed movement in three different directions of an actuator which affects the releasing mechanism is required.

Abstract: The present invention is for standing boards that may be connected to buggies or prams which do not have a rear wheel shaft or otherwise are so designed that connecting of the standing board to the rear shaft is not always suitable. The standing board has a board, wheels at the rear end of the board, and mounting arms which connect the standing board to the buggy. The mounting arms are so designed that there is free space for the wheels of the buggy, possible breaking means etc., thus the mounting arms are curved so that they extend forwards and upwards from the board. The mounting of the arms at the standing board is such that the arms may take one out of several distinct positions relative to the board and when in use are fixedly arranged relative to the board. For this purpose the arms are fixed into bushings which in turn are fixed into mounting parts which preferably are integrated parts of the board of the standing board.

Abstract: The present invention is for a device for mounting of wheels so that they may move in a preferably vertical direction at right angle to the wheel shaft. The invention is also standing board for prams having such wheel mounting. At its from end the standing board has a mounting means by which the standing board is pivotably mounted to the rear axle of a pram the main direction of movement of which is shown by arrow. The turning shaft of the wheel is mounted in a movable sleeve the movements of which are controlled both by a brushing which surrounds the sleeve and by a tube which is partially inserted into a groove in the sleeve. A spring is placed into the groove in the sleeve so that the spring contacts both the bottom of the groove and the end of the tube which penetrates the groove.

Abstract: The present invention is for standing boards for buggies and prams of such design that the standing board also may be connected to buggies or prams which do not have a rear wheel shaft or otherwise are so designed that connecting of the standing board to the rear shaft not always is suitable. The standing board has a board, wheels at the rear end of the board and to mounting arms which connect the standing board to the buggy. The mounting arms are so designed that there is free space for the wheels of the buggy, possible breaking meant etc., thus the mounting arms are curved so that they form circle parts and extend themselves forwards and upwards from the board. The mounting of the arms at the standing board according to the invention is such that the arm take one out if several distinct position relative to the board and when in use are fixedly arranged relative to the board.

Abstract: The invention relates to a foldable or retractable ladder, especially for use at an opening in the ceiling, for example, to an upper story such as an attic in a building or the like, which ladder comprises a plurality of sections (11,12,13) arranged in operative position of the ladder, in such a manner, that the upper section (13) of the ladder by hinge members (15) is pivotally attached to a frame (14) for the door opening, and the folding-down movement of the ladder is limited by a toggle joint arrangement (16, 17) attached to the upper section (13) of the ladder. The toggle joint arrangement consists of two toggle joints attached to each side of the frame and, respectively, each side rail of the ladder and interconnected at the ladder by means of an axle (18) extending in parallel with the runs.
