Description

Fastening device between footwear and skis, snowshoes or ice skates.

Title

Method for adjusting the size of a fastening device between footwear (such as shoes or boots) and skis, snowshoes or skates where there is no need for specially adapted footwear (such as ski boots).

The purpose of the invention

A binding (binding) that consists of a part that embraces the front of the shoe and a part that embraces the rear (heel) part of the shoe. In order to be able to adapt the length of the binding between the front and rear parts to suit a very wide variety of shoe sizes while maintaining stability between the front (figures 1 – 3) and rear (figures 1 – 4), a spacer pin or plate can be used, figures 1- 2 and figure 2. If a binding is adapted to a large range of sizes and this spacer pin or plate can only be adjusted at one end, it will, in the case of small sizes, protrude beyond the size of the footwear. Since a binding of this type is often hinged at the front, this spacer pin or plate will usually protrude at the rear. Something protruding far behind the heel of the footwear could be very harmful to the user during active use, a fall or accident. The injuries that may occur will be to the user themselves or to the equipment, typically in the area of the user's gluteal muscles or lower back. The injuries may be personnel injuries or damage to equipment such as clothing and equipment.

The purpose of this invention is to create a binding that can be adapted to a very large range of sizes without parts of the device that are to regulate the size of the binding falling outside the physical size of the footwear.

The method that solves this problem is that the distance between the front part (figure 1 – 3) and the rear part (figure 1 – 4) of the binding can be adjusted by means of a spacer pin or plate (figure 1 – 2 and figure 2) that can be adjusted longitudinally on both the front and rear binding parts (figure 1 – 1 and figure 4). The method of attaching this spacer pin is done in a way that it can be changed on both binding parts independently of each other.

Background to the invention

After several years of teaching skiing, it has become clear to the inventor that just a small amount of slack between the binding and the ski will significantly delay the learning of skills and reduce mastery of skiing. The bindings known to the inventor that do not require specially adapted footwear are not stable enough or large parts protrude from the binding that can be harmful to the user or their equipment, especially for small sizes.

When searching for similar solutions on the internet, digital museums and patent databases, no solution has been found that is the sought-after method for adjusting the sizes of bindings for skis, snowshoes or ice skates.

The invention in this application solves the problem mentioned above by ensuring that parts of the binding do not protrude beyond the size of the footwear. The method for adjusting the size of the binding as described in the patent of Linken AS, (Patent no. 306540) does not solve the described problem. Nor do the Finnish OAC (patent no. FI12958 and EP3799939) bindings solve this challenge. A slightly different way of solving the adjustment of binding sizes is made by Serket Patrol Ski Binding, here the size is also adjusted only at the back.

For all of these bindings, the spacer pin or plate is between the front and rear binding parts so that it can only be adjusted at the rear binding part and it is fixed at the front binding part. Here, much of the spacer pin will therefore protrude at the back, especially when the binding is set for small sizes.

Furthermore, various solutions for adjusting the size are known from US 5560633, RU 200959, US 200649929, US 4135734, US 2007289169 and US 6189911, but these bindings do not solve the problem either.

The invention in this application is characterized in that the distance to the rear (figures 1 – 3) and front (figures 1 – 4) binding part can be adjusted independently of each other and can be moved along a spacer pin or plate (figures 1 – 2 and figure 2). The described method will avoid any binding part protruding from the size of the footwear. The attachment between the spacer pin or plate and the binding parts can be made with, but not limited to, rivets of various materials and types, screws and bolts of various types and bent metal parts in connection with the binding parts or the spacer pin, plate. An example of the selected method is shown in figure 1-1 and figure 3.

Short summary

The invention relates to a method for adjusting the size of a fastening device between footwear and skis, snowshoes or ice skates.

The invention in this application is characterized in that the distance between the rear (figure 1-4) and front (figure 1-3) binding parts can be adjusted independently of each other and can be moved along a spacer pin or plate (figure 1-2). In this way, it will be avoided that any binding part protrudes from the size of the footwear beyond the part of the binding that encloses the front and rear parts of the footwear.

Requirements for the method that solves this are:

Requirement 1: The adjustment of the distance between the front part (figure 1-3) and the rear part (figure 1-4) of the binding can be adjusted on the front and rear binding parts, respectively, independently of each other.

Requirement 2: The distance between the front part of the binding, figure 1-3, and the rear part of the binding, figure 1-4, can be adjusted without any part of the binding exceeding the length of the footwear being used.

Requirement 3: The method of attaching the spacer pin or plate (figure 1-2 and figure 2) between the front part of the binding (figure 1-3) and the rear part (figure 1-4) is done with rivets of various materials and types, screws and bolts of various types, bent metal parts such as those used in figure 1-1 and figure 3, or bent parts incorporated into the binding itself.

Brief description of the drawings

Figure 1 should be presented together with the summary.

Figure 1: This figure shows the attachment device between footwear (such as shoes or boots) and skis, snowshoes or skates where there is no need for specially adapted footwear (such as ski boots). Note the adjustment possibilities (figure 1-1 and figure 3) on both the front (figure 1 – 3) and rear binding parts (figure 1 – 4).

In order to be able to adapt the length of the binding to a very large variation in shoe size while maintaining stability between the front and rear sections, a spacer pin or plate can be used (figures 1 – 2 and figure 2).

Figure 2: This is an example of a spacer pin / spacer plate. Here it has been chosen to use cutouts in the plate that can be used to fix the position of the spacer pin between the front and rear binding. The attachment between the spacer pin or plate and the binding parts can also be made with, but not limited to, rivets of various materials and types, screws and bolts of various types and bent metal parts in connection with the binding parts or the spacer pin, - plate. An example of the chosen method is shown in Figure 1-1 and Figure 3.

Figure 3: This is the chosen method for fixing the spacer pin in Figure 2 to the front and back binding as shown in Figures 1, 3 and 4.

Figure 4. This figure shows a clarification of where the mentioned binding parts are. This is the back binding, the front binding of the spacer pin/plate. Here the fastening device (the multi-binding) is shown in the elevated position.

Concrete examples

For this invention to work, one relies on a binding that consists of a front part and a back part. The front part encloses the front part of the user's footwear while the back part encloses the back part / whole of the footwear. The front part and the back part are connected together by a spacer pin or plate. Figure 1 - 2.

To avoid parts of the spacer pin or plate protruding beyond the user's footwear, it is essential that the spacer pin or plate can be adjusted and attached independently of each other to the front binding and the back binding. This can be done by having grooves or holes in the spacer pin or its sides. These grooves can be used to lock the position of the spacer pin or plate to the front or back binding. The attachment between the binding parts and the spacer pin or plate can be made with rivets of various materials and types, screws and bolts of various types and bent metal parts in connection with the binding parts or the spacer pin, plate. The spacer pin or plate can also be locked by means of friction where another material surrounds the spacer pin or plate in such a way that it cannot be moved longitudinally.
