Description

DETAILED DESCRIPTION OF THE INVENTION The present invention incorporates one foot insert;
A self-levitating water ski consisting of an inflatable float with a rod, stake, tube or piece of wood longitudinally connected to the outside of its bottom as a strength member.

Such water skis are subject to Dutch patent application no.
Known by No. 8103271.

In that application, the foot is retained within the foot insert by a toe band mounted within the foot insert. Furthermore, the strength member in the known water ski is entirely enclosed within a sleeve which is fixedly connected over its entire length to the outside of the bottom of the float.

The object of the present invention is to provide a configuration for a foot insertion member;
The object of the present invention is to provide a self-floating type water ski which is improved both in terms of structure and structure for attaching a strength member to the outside of the bottom of the float.

To this effect, according to the invention, said foot insert is formed as a chamber with flexible walls accessible from the top of the float, said walls increasing their height in the operating state of the float. are in longitudinal abutment over a substantial portion of the float and are set back in relation to each other toward the bottom of the float, the walls extending along their top ends; fixed to the walls of the float at their enlarged bottoms and around the entire circumference of the bottom of the float, said rod, stake, tube or wood chip-like strength members being fixed to the outside of the bottom of the float; A self-levitating water ski of the type described above is provided, characterized in that it is attached to the bottom of the float by means of shaped members.

The foot insertion member according to the present invention includes an ankle and
The cushion is configured so that the entire foot, except for the sole, which is placed on the footboard, is covered by the cushion.

The foot insert holds the foot firmly with pressure evenly applied over its entire circumference, and on the other hand, when the foot is removed from the float, it is easily pulled out of the foot insert constructed according to the invention. be able to.

Another advantage is that the foot insert according to the invention can adequately prevent water from entering the foot insert, whether in use or not.

Regarding the installation of strength members, two or more strength members can be applied;
The position of the eye-shaped element, which is preferably made of synthetic resin material, such as the support of a water ski, is such that the weight of the skier can be transferred directly to the strength member via the foot plate in the foot insert. It can be said that it was selected as

A substantial advantage of the mounting arrangement according to the invention is that it not only provides adequate strength in the longitudinal direction of the float, but also that damage to the bottom of the float is avoided. The risk of leakage is therefore reduced. In fact, the strength members and synthetic resin eyes can be damaged by contact with the ground when a skier walks on land or when skiing on water, but these parts are free to expand. It is much less susceptible to damage than regular floats.

Next, an embodiment of the present invention will be described by way of example with reference to the following attached drawings: FIG. 1 is a plan view of a self-levitating water ski having a foot insertion member according to the present invention; FIG. 2 is a self-levitating water ski according to the present invention; Figure 3 shows the bottom view of the self-levitation type water ski shown in Figure 2.
FIG.

The foot insert 6 has a foot plate 1, the wall 2 of which is welded around its entire circumference to an inflatable float 3 at its top and bottom.

A tube-shaped strength member, designated 4, is inserted into an eye-shaped member 5 made of synthetic resin. Skier's weight is on footboard 1 and float 3
is transmitted to the tube 4 through the bottom of the tube.

The foot insert 6 has a closed bottom, as shown in the width direction in FIG. However, the central part of the bottom, calculated from predetermined distances to both sides, may also be omitted. Care should be taken in that case that the distance on each side is sufficient to ensure proper attachment of the foot insert to the bottom of the float, for example by means of glue or the like.

The self-levitating water ski described above and shown in the drawings may, of course, be modified in various ways without departing from the scope of the invention.

Claims (1)

[Scope of Claims] 1. An inflatable float with an integrated foot insert and a rod, stake, tube or piece of wood connected longitudinally to the outside of its bottom as a strength member, said foot insert The member is formed as a chamber with flexible walls accessible from the top of the float, said walls being longitudinally adjacent to each other over a substantial portion of their height in the operating condition of the float. in a received state and retracted in relation to each other towards the bottom of the float, the walls extending along their top ends and at their enlarged bottom to the walls of the float and the bottom of the float. It is fixed around the entire circumference, and the rods, stakes,
1. A self-levitation type water ski, characterized in that a tube or wood chip-shaped strength member is attached to the bottom of the float by an eye-shaped member fixed to the outside of the bottom of the float. 2. The self-levitating water ski according to claim 1, wherein the strength member is formed from a thin-walled aluminum tube whose both ends are sealed with insert caps.
