Patent SE-468640-B (SE)
Title: Wheel undercarriage for carriages and carriage provided therewith
Inventor: AHLSEN J B B
IPC: B62B3/00
Filed: 1990-10-22
Abstract: A wheel undercarriage for carriages has at least three wheel units 29-32, which are rotatable about their respective steering axle 33-36. The steering axles extend perpendicular to the wheel axle 45-48 of the wheel units and, viewed in a plane parallel with the wheel axles, are widely spaced and extend through this plane at points at least one of which lies at a distance from a straight line running through two or more of the other points. The wheel undercarriage has a drive mechanism 37-43 for rotation of the steering axles 33-36 and adjustment thereof, and hence of the wheel axles 45-48 of the wheel units mounted on the said steering axles, into four different adjustment positions, namely firstly a first position in which the wheel axles 45-48 of all the wheel units are parallel with one another and extend in a first direction, secondly a second position in which the wheel axles of all the wheel units are parallel with one another and extend in a second direction perpendicular to the said first direction, thirdly a third position in which extensions of the wheel axles of all the wheel units mutually intersect at a common point of intersection 44, and fourthly a fourth position in which the wheel axles deviate from parallelism with one another and in which at least one wheel axle is placed in a direction other than towards the said point of intersection 44. This configuration enables the wheel undercarriage to be displaced in two mutually perpendicular directions (the first and second positions), rotated or turned (the third position) and parked (the fourth position). <IMAGE>

Title: Locking member suitable for a cabinet, a chest of drawers or the like
Inventor: FRANZEN HANS MAGNUS LUDVIG
IPC: E05B65/467
Filed: 1991-09-09
Abstract: The invention relates to a locking member 10 which is suitable for a cabinet 1, a chest of drawers or the like and can be applied to and removed therefrom, in which the cabinet comprises a number of drawers which can be slid horizontally in and out using a handle or a knob. The said locking member 10 is arranged such that in an applied position it extends between an upper drawer 2 and a lower drawer 6 and past one or more intermediate drawers 3,4,5 and interacts with the said drawers such that it bars a horizontal displacement, such as a sliding- out, of a drawer relative to every other drawer orientated adjacent to the said locking member. The one end section 4 is formed with a slot, expediently of a width such that the said end section can pass with little play past a middle section belonging to the knob 6a and situated between the front face of the drawer and a handgrip-suited surface section belonging to the knob. An intermediate section 12 is suited to bearing against or facing, with a first edge face 12a, a middle section, belonging to the respective knob, for the intermediate drawers. The second end section 13 is suited to bearing with an edge face 13b against the said middle section for the knob 2a belonging to the uppermost drawer 2 and the one end section interacts with a spring member 8, suited to being able to press the second end section 13 against the said middle section. <IMAGE>

Title: Studded footwear
Inventor: PAUL ANDREW KELLY
IPC: A43B5/02
Filed: 2003-02-17
Abstract: A shoe stud for a sports shoe has a ground-engaging part and a multi-start threaded spigot for engagement in a complementary socket on a receptacle secured in the shoe sole or heel. The stud and receptacle also have a locking device which inter-engages when the spigot is fully inserted into the socket, to resist unscrewing. In order to ensure that the stud takes up a precise position relative to the receptacle, which may be needed if the stud is not rotationally symmetrical, the stud and receptacle have means to determine the initial position of the stud relative to the receptacle, and means to determine the final position of the stud relative to the receptacle. Determination of the initial position may be provided by a thread and complementary groove of the screw-thread connection which are of different dimensions from the others.
