BOTTOM STRUCTURE FOR INLINE ROLLER SKATE SHOES
Field of the Invention
This invention relates in general to inline roller skate shoes, more specifically, to an improvement in a bottom structure for inline roller skate shoes.
Description of the Prior Art
The mounting blocks (mounting points) of the bottom structure of the present inline roller skate shoes are used to mount roller frame, as shown in Figure 1. The distance between the two mounting blocks on the bottom of inline roller skate shoes is preset at 165mm and the diameter of typical rollers is equivalent to or less than 84mm. Thus, five rollers can be mounted to each inline roller skate shoe at same time. To have a diverse product line, producers usually increase the roller diameter to 100mm. In this way, only four rollers are needed for the inline roller skate shoes which reduce the number of rollers and the time required for assembly.
However, with the 100mm rollers, if the distance between the mounting blocks remains 165mm apart, the space between the shoe bottom and the roller frame will not be sufficient to accommodate the larger rollers and causing the contact between rollers and shoe bottom which as a result impeding the roller motion. In another typical set up where one larger roller is placed at the front and back end and two smaller rollers are placed in the middle of roller skate shoes. However, because smaller rollers turn more times than larger rollers, roller motion can become inconsistent and causes concern for speed and safety.
Therefore, in order to solve the problem with 100mm or above rollers, it is necessary to increase the space between roller frame and shoe bottom. However, this increase in space inevitably elevate wearer's center of gravity and as a result, reduces and hinders the operatability and stability of the roller skate shoes for the wearer.
If no change is made to roller frame structure, the bottom of inline roller skate shoes cannot accommodate enough rollers. Thus, the distance between the mounting blocks of the
shoe bottom generally adjusted to 195mm. In this way, without changing other parts, four 100mm or above rollers can be mounted at same time. But this method also brings about a new problem. With only four 100mm rollers mounted, the shoe bottom will experience increased pressure. If the thickness of shoe bottom is not increased, swinging will occur during skating. If the thickness is increased, the weight of the shoes will also be increased and this will slow down the skater and reduce the operatability.
Therefore, current technical drawbacks need further improvement and development.
Summary of the Invention
The objective of this invention is to provide an improved bottom structure for inline roller skate shoes. Through designing layered structure for shoe bottom without increasing shoe weight, the invention is to increase the strength for shoe bottom and improve the safety of using inline roller skate shoes.
The new technology for the invention is as follows:
The bottom of inline roller skate shoes in the invention comprises of multiple layers of carbon fiber or glass fiber fabric and a soft X-shape chassis installed in between of any carbon fiber or glass fiber fabric layer for supporting the two mounting blocks on the bottom structure for mounting rollers.
The abovementioned bottom structure of inline roller skate shoes, wherein the distance between the said mounting blocks is 195mm or 165mm.
The abovementioned bottom structure of inline roller skate shoes, wherein the said carbon fiber or glass fiber fabric layers consist of 11 layers.
This invention provides an improved bottom structure for inline roller skate shoes. By installing a soft X-shape chassis in between any of the carbon fiber or glass fiber fabric layer at the bottom of inline roller skate shoes increases the shoe's strength and tenacity, thereby improves the safety and operatability of inline roller skate shoes.

Detailed Description of the Preferred Embodiment
The following provides a detailed description for the preferred embodiments for the invention.
The inline roller skate shoes 100 for the invention as shown in Figure 2 and Figure 3 adopts carbon fiber or glass fiber fabric to make the shoe bottom. The structure for the shoe bottom comprised of a lamination of multiple layers of carbon finer fabric. There are 11 carbon fiber or glass fiber layers 110, laminated manually layer by layer. The new structure for shoe bottom in the invention can use other number of carbon fiber layers and has a soft X-shape chassis 120 installed in between of any layers. For example, it can be installed in the second layer or the third layer in the shoe bottom, as shown in Figure 4. Each shoe has one soft X-shape chassis 120, which supports the two mounting blocks 121 in the abovementioned shoe bottom. The two mounting blocks 121 have corresponding screw holes 122 for mounting roller frame.
The X-shape chassis is formed by a foam material or a wax type material (hot melt type material) providing the light weight. When using a wax type material in producing a X-shape chassis, we can heat them up and let that material out of the shell to provide a extremely light weight in construction.
The bottom structure for the inline roller skate shoes in the invention wherein the two mounting blocks 121 is set to be 195mm or 165mm apart and said mounting blocks are installed during lamination of carbon fiber or glass fiber layers.
The bottom structure for the inline roller skate shoes in this invention wherein the two
mounting blocks 121 is set to be 195mm or 165mm apart and, wherein in between the space, a soft X-shape chassis, which can be made from PVC, is installed and multiple layers of carbon fiber or glass fiber fabric are then laminated onto the shoe bottom. This bottom structure is better for all kinds of wheel mounting with a lighter weight but stronger strength.
The structural nature of the abovementioned soft plastic chassis is lightweight and possesses vibration absorbing capability; when the soft X-shape chassis is installed into the carbon fiber or glass fiber fabric layer, it will enhance shoe bottom's strength allowing it to become as tough as steel bars, while also increasing the tenacity of the shoe bottom without increasing shoe weight. In addition, applying pressure to the rollers during rolling motion will not affect the rolling speed and safety. Thus, the invention provides enhanced strength for the shoe bottom of the inline roller skate shoes.
It is understandable that people skillful in this area can easily make alterations or modifications base on the above application; thereby all these alterations and modifications shall be covered in the scope of the claims in this invention.
