US 4872665 AAbstract
The joints whose axis is roughly perpendicular or parallel to the center plane and which are situated in the saddle zone and connected to the telescopic devices are preferably placed in this order, extending from the saddle towards the telescopic devices, but the reverse order is possible with the present invention. The terms "roughly parallel" or "roughly perpendicular" are used to define a certain number of directions characteristic of the invention, such as the directions actually selected for technological commodities which may deviate by up to 15� or 20� for example from the pure parallel or perpendicular direction, but without resulting in a modification of the basic function of the joint in question.
FIGS. 6, 7 and 8 represent a first type of device 2 for securing the saddle to the hips. It is composed firstly of a part 2a connected to the rear of the saddle by a joint 8 whose axis is perpendicular to the center plane of the body and saddle. The role of the joint 8 is to continuously exert a thrust towards the top and front of the saddle, whilst permitting slight angular movements and folding up onto the saddle for arrangement. This part 2a preferably has an open-ended rigidity so as to keep the zone of joint 8 in a sufficiently rigid position without causing the individual discomfort. The zone situated behind will thus be more rigid than the zone in front which is closed with a belt buckle. The material comprising the part 2a may, for example, be a flexible thermoplastic such as PVC, either of open-ended thickness or reinforced in places by fabrics crossworked at 45�. The material can also be an elastomer such as polyurethane for exampe, also having an open-ended thickness and locally strengthened by fabrics crossworked at 45�. The part 2b is a flexible strap, possibly slightly elastic, which connects the front extremity of the saddle to a detatchable link on the belt buckle of the part 2a.
There are two main castors 42 and 43 whose axes are perpendicular to the axis of the telescope and inclined about 60� in relation to the center plane of the body, the contact surface of the castors being tangential to the male or upper part 3s of the telescope. There is also a secondary castor 44 whose axis is perpendicular to the axis of the telescope and roughly perpendicular to the center plane of the body. This system of 3 castors keeps the tubes 3s and 3i apart from each other, even in the presence of a significant radial force. The main torque force is received by the castors 42 and 43 which are disposed at the front of the telescope in relation to the individual.
