摘要:
Ski holding apparatus is disclosed which comprises a rack for supporting a plurality of skis in a substantially common plane. The rack features pairs of holders arranged across the rack with the holders of each pair spaced apart along the rack so as to support at least one ski, or preferably a pair of skis at two spaced apart locations.The holders are adapted to support the skis in inclined positions in which the mean transverse plane of the skis is arranged at angle of 30.degree. to 60.degree. to said common plane.In this way the skis on the rack require less space. The rack can either be used on vehicle roofs, in ski rooms, or in storage spaces within vehicles. Each holder is conveniently closed by a closure member to retain the skis.Various types of closure are described in which the individual closures for each holder may be either resilient or rigid and may also be supported from a common clamping arm.

A cross country ski binding has a support element attachable directly to a ski for engaging a forwardly extending boot sole extension, and is also provided with latching mechanism for latching the sole extension to the supporting element, under imposition of spring forces. The cross country ski binding may include spring biased detent members engageable into detent provisions provided directly on the boot sole extension, such that the forward part of the ski boot is automatically locked in position upon insertion of the boot sole extension into the support element. Preferred embodiments of the invention include those accommodating an axial movement of the boot sole extension into the support element and latching mechanism, as well as embodiments wherein the boot sole extension is placed downwardly over a pivot pin forming part of the holding mechanism. Also, certain embodiments of the invention include additional locking levers for locking the latching mechanism in a latched position. Further, certain preferred embodiments include camming means, as well as ratchet and pawl means for performing the latching function interconnecting the support element and the cross country ski boot sole extension.

A cross country ski binding includes a support element which has a rear part clampingly engageable with a forward extension of a ski boot sole and a front part which is fixedly attachable to a ski. In order to accommodate angular movement between the front and rear parts, a latching mechanism is included which permits such angular movement about cross axes extending crosswise of the longitudinal extent of the ski when the binding is in an in-use position. The forward extension of the boot sole is formed as a short articulation part for hingedly connecting the boot to the latching mechanism. In preferred embodiments the forward boot sole extension formed as the articulation part extends less than 15 mm forwardly from the toe accommodating part of the boot, such that the boots can be comfortably walked in when not skiing.

A cross country ski binding for securing a ski shoe by a forwardly directed extension of its sole to a ski features a recess defined between two side walls, a top wall and a base plate with at least one and preferably two bracing members arranged within the recess and extending vertically at right angles to the top wall of the recess. The bracing members are adapted in operation to engage in corresponding longitudinally extending slots in the sole extension and serve to stiffen the recess and to react the tilting moments occuring during skiing. A securing device in the form of a toggle lever mechanism includes a hooked member which serves to engage behind a corresponding projection on the sole extension to draw the same into the binding and to prevent the ski shoe from moving rearwardly out of the binding.Various modifications are disclosed including an embodiment in which the bracing members are formed by inwardly turned portions of the sheet metal base plate of the binding.

A cross-country ski binding is provided which includes a boot sole holding member engageable with a boot sole extension to hold the same in position on a ski. Guide structure is provided at a bearing member fixed to the ski, which cooperates with a corresponding guide part of the holding member to guide the holding member to move in a forward longitudinal direction during its movement into the sole-holding position so that the boot sole is pulled forwardly into the binding as it is clamped into position.
摘要:
A cross country ski binding of the type in which a forwardly extended portion of the sole of a ski shoe is received by and fixed into a chamber fitted to the ski. In the present arrangement an over center linkage is arranged generally in front of the chamber and includes a clamp portion with a hooked end which fits over the top of the chamber and engages an abutment on the upper side of the extended sole portion so that on engaging the binding by actuation of the over center linkage the hook is pulled forwardly to secure the ski shoe within the binding. An especial feature of the arrangement is that the clamp is arranged as a resilient spring which obviates the need for resilience elsewhere in the binding. Actuating means are provided which allow the skier to open and close the binding from a standing position with a ski pole. In a modification an auxiliary spring fastened to the clamp is used to assist disengagement of the hooked end of the clamp.

A measuring device and method according to the invention for registering an ambient temperature Ta of a medical machine including a measuring housing, which is arranged on an outer wall of the machine and in which at least one temperature sensor remote from the machine and at least one temperature sensor (16, 16′) near to the machine are held, wherein the at least one temperature sensor remote from the machine registers a first temperature T1 and the at least one temperature sensor near to the machine registers a second temperature T2, and an evaluation apparatus configured to establish the ambient temperature Ta using a difference between the first temperature T1 registered by the at least one temperature sensor remote from the machine and the second temperature T2 registered by the at least one temperature sensor near to the machine.
摘要:
A process for the preparation of polyricinoleic acid esters comprising the step of reaction of ricinoleic acid with an alcohol component which comprises mono- and/or polyfunctional alcohols having a molecular weight of ≧32 g/mol to ≦40 g/mol, wherein the reaction is carried out at least partly in the presence of a catalyst. The amount of catalyst, based on the total weight of the ricinoleic acid and the alcohol component, is in a range of from ≧10 ppm to ≦100 ppm. The reaction is ended when the acid number of the reaction product obtained is ≧5 mg of KOH/g to ≦100 mg of KOH/g. The invention furthermore relates to a polyurethane polymer, in particular a flexible polyurethane foam, which is obtainable using these polyricinoleic acid esters.
