Abstract
ABSTRACT
The Road Slalom Gate allows skiers to train in the summer in conditionssimilar to those of a winter slalom course.
The Road Slalom Gate is composed of a rubber base and a light weight tube vertically attached to the base through an articulation mechanism. The articulation allows the tube to move in any direction when stuck by a passing skater and to recover to its initial vertical position immediately after.

SPECI~ICATIONS
A slalom gate is a vertical pole arolmd which the skier must pass with his/her skis in a predetermined direction. A winter slalom gate is planted hlto the snow to such a depth as to withstand the impact of a skier. In addition, a slalom gate has an articulation which enables the gate to fall when hit and to recover to a vertical position immediately after impact.
The Road Slalom Gate is designed to function exactly the same as a winter slalom gate and is used by skaters wea~ing in-line skates. Unlike the winter slalom gates, the Road Slalom Gate rests on the surface of the road. The road surface is not penetrated or affected in any way.
A basic requirement in a slalom pole is that it must articulate at the ground level, so that there wiU be no other resistance against the passing skater than the weight of the pole itself.
In all prior attempts, winter slalom poles have been used, with different base types. However, due to the weight of the winter slalom poles all these solutions have difficulties securing the base to the road surface. In one example the base had to be weighted down with sand bags. In another instance, the base was glued to the road surface. Such solutions are impractical and make this type of training inaccessible to the majority of the skaiters.
The Road Slalom Gate solves these problems by using a lightweight pole made of reinforced foam tube 125 cm high, attached to a flexible rubber base.
The rubber base rests freely on the surface of the road and provides stability to the vertical pole~through its weight. Due to its flexibility, the rubber basewiU adjust to match the road surface variations.
In road trials, I have found this solution to be ve~y beneficiary to skiers, as it eliminates the inhibition caused by the impact with a solid slalom pole.
Unlike the winter slalom gate, the Road Slalom Gate does not require the use of almour, other than the normal protection gear used by the in-line skaters.
The drawings which illustrate the Road Slalom Gate are:

SPECI~lCATIONS cont.
Figure 1 is a vertical elevation of the Road Slalom Gate assembly. The pole is attached to the base through the articulation mechanism. When struck by a passing skater, the pole moves away allowing unobstructed passage.
The Road Slalom Gate assembly consists of the rubber base, the lower coupling piece, the articulation mechanism and the foam pole. The lower coupling piece is attached to the rubber base. The articulation mechanism is attached to the pole. These two assemblies can be put together or taken apart through the lower and upper coupling pieces which are threaded. This design also allows for compact storage and transportation.
Figure 2 is a horizontal plan of the pole and base assembly. This drawing shows where the pole is placed on the base. The pole placement on the base allows the same base to be used for left and right turning gates.
Figure 3 is a section through the articulation mechanism. The articulation mechanism is composed of the threaded upper coupling piece, the rubber washer, the rubber disk, the pole holding cap, the elastic cord casing tube and finally the elastic cord. The elastic cord is tensed and holds together a11 the listed components. When tightened onto the lower coupling piece, the articu1ation mechanism allows the pole to move in any direction, up to 90 degrees from the vertical.
Figure 4 is a vertical section through the articulation mechanism with the pole pushed away from its vertical resting position. This section illustrates how thearticulation mechanism works.
The articulation mechanism allows the pole to recover to vertical position immediately after the impact. The rubber washer allows the pole to move and recover with ease to and from small angles from the vertical, where the momentum generated by the pole's own weight is small. The larger rubber disk generates enough momentum to raise the pole to vertical from any position. This function is also aided by the rubber foam disk which rests on the base. When the pole falls, the rubber disk compresses the rubber foam ring. All the energy generated by the falling pole is absorbed by the elastic cord and the foam ring. This energy is used to lift the pole to the vertical position.
Pigure 3 also shows the foam tube composition. The major two properties of this pole are its strength and ]ight weight. The pole strength is obtained through an outer layer which tightly covers the pole and through an inner rigid tube. The inner tube distributes the irnpact force over a larger area and in thesame time aUows the pole to remain flexible.
