Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a set of shoes and skates for ice skating.

Skates called Norway pears have been used for more than half a century for traditional skill competitions and general skating. This type of skate consists of a hollow base made by bending a metal plate and a pair of polished and hardened blades (slides) with edges.The blades are inserted between a pair of parallel long edges of the base. It is fixed by welding. Opposite said long edge of the base body there are means for fastening to the sole of the skate.

The hollow base body has a substantially circular cross-sectional shape, and on its upper surface are welded or soldered two supports formed from metal plates into a substantially truncated cone shape, each support having a large diameter at its upper end. Welded to the mounting plate. The mounting plate is secured to the sole or heel of the shoe with screws or rivets, and the base body is further secured to an elongated support located near the toe of the sole.

Problems to be Solved by the Invention With the conventional skates described above, it is virtually impossible to attach the skate to the shoe with an easily releasable coupling means, such as is commonly employed in skis. Therefore, it is necessary to use skate protective covers when going to and from skating rinks, etc., which is very inconvenient.

Additionally, the manufacturing process for the skates described above is complex and requires considerable manual labor. Please note that this skate is relatively heavy.

Furthermore, since the mounting plate is shaped to match the shape of the sole of the shoe, skates for the right foot and skates for the left foot are different, and two types of skates must be kept in stock to replace damaged skates.

The object of the present invention is to provide a skate and shoe set that overcomes the above-mentioned disadvantages of conventional skates.

In order to achieve the above object, the present invention provides a skate and skate set including a base body having a blade fixed thereto and having means for fixing it to the bottom of the skate shoe on the opposite side of the blade, the skate base being The upper surface of the skate is flat, the sole of the skate is approximately flat, the sole has a dovetail groove, and the bottom of the groove is a flat surface that corresponds to the upper surface of the skate base; This set of skates and skate shoes is characterized in that it can be fitted into the groove and that at least one of the skate base and the sole is provided with a locking means for fixing the skate base fitted in the groove.

This configuration allows the skate to be quickly attached to and removed from the shoe. Furthermore, since the soles of the shoes are almost flat, it is possible to walk while wearing them. Therefore, the user of these skates can wear the skates and go to a rink or the like and attach the skates there with a simple operation. All you have to do is take off your skates when you leave. In addition, even if the water conditions are poor, such as under a bridge, there is no need to wear protective skate covers and walk unsteadily as before. Furthermore, it is easy to replace damaged skates.

It is preferable that the shape of the upper wall surface of the base of the skate of the present invention and the bottom surface of the dovetail groove of the sole is an elongated trapezoid, and further,
Preferably, the wide side of the trapezoid is on the heel side of the shoe. The trapezoid shape naturally locks the skate in place, and the wider trapezoid on the heel side allows for better load distribution and improves the aerodynamic shape of the skate. Further, it is preferable that the locking means is provided on the heel side.

Since the right-foot and left-foot skates are identical, it is easier to install, remove, or replace the skates, and the skates are also easier to manufacture and store.

EXAMPLES Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 shows an embodiment of the skate of the present invention.

The base 1 of this skate is a single piece made of a metal plate bent along two fold lines 2, and has a flat top surface 3 and two side surfaces 4. The lower edges 5 of both side surfaces 4 are bent and parallel to each other with narrow intervals. A blade 6 of a normal shape is inserted and fixed between the lower edges 5 on both sides.

A and B in FIG. 2 show cross sections taken along lines IIA-11A and JIB-11B in FIG. 1, respectively. The skate base 1 made as described above has a substantially triangular cross section at any point, and in this embodiment the width of the upper surface 3 is narrower at the front of the skate and wider at the rear. Furthermore, the height of the base body 1 is lower throughout the skate and higher at the rear.

In order to be able to remove the skates from the skates and walk while wearing them, the shoes have the structure shown in FIG. 3, for example. The sole 7 of this skate 8 is relatively thick and mostly flat. The sole 7 has a dovetail tenon shape (i.e.
There is a groove 9 (width increasing towards the bottom), and the bottom 1
The shape of 0 is the same as the shape of the upper surface 3 of the skate base 1,
The inclination of the side wall surface 11 of the groove 9 is approximately equal to the inclination of the side surface 4 of the base body 1. A skate can be inserted into this groove from the rear end of the dovetail groove 9. The inserted skate naturally stops at an appropriate position within the wedge-shaped dovetail groove and becomes locked, and in this state is fixed by a latch provided on the skate base 1 or the sole 7. The latch is shown schematically as 12 in FIG. 1 and 12' in FIG. The type of this latch is arbitrary, and a detailed explanation will be omitted here.

In order to prevent the opening of the dovetail groove 9 from widening due to bending of the sole 7, a metal reinforcing member may be embedded in the sole 7.

The manufacture of the skate base 1 is simpler than the manufacture of conventional skate bases, including welded supports and mounting plates, and the skate is also lighter and has lower air resistance than conventional skates. This skate has a large area of contact with the shoe along its entire length, which increases bond strength. A laser tool can be used for cutting and joining during manufacturing of the base body 1. It is also possible to omit the skate blade 6 and instead weld the lower edges 5 of both sides of the base together and then harden them using a laser beam, diffusion of a steel hardening agent, or the like.

Moreover, the blade 6 can also be made of ceramics.

It is also possible to form the skate base 1 from a plastic material, in which case it is preferable to use carbon fiber reinforced plastic. The blade 6 can be inserted during the molding of the plastic and optionally has tabs or holes formed in the upper edge of the blade to provide a strong bond with the plastic.

Since this skate 1 does not need to be manufactured separately for right and left feet, manufacturing and storage are simplified. It also makes it easier to replace damaged skates, and you can quickly install skates because you don't have to check left and right. If it is necessary to attach the right-foot skate and the left-foot skate at different angles, it is convenient to make the shapes of the soles 7 and the angles of the grooves 9 of both shoes different to meet the needs.

The skate according to the present invention is not limited to those used for speed competitions or long-distance skating as in the illustrated embodiment, but it is also possible to create an ice hockey skate of the same structure by appropriately changing the shape of the front end. Of course it is also possible.

Although it is preferable for the top surface 3 of the skate base and the bottom surface 1o of the groove 9 to have the shape shown in the figure with regard to the fixing effect, load distribution and aerodynamic shape of the skate, it is also possible for these two surfaces to be rectangular. You can also make it wedge-shaped in the opposite direction.

Further, if necessary, a stopper may be provided for regulating the position of the skates.

As described in detail, the skate and shoe set of the present invention makes it extremely easy to put on and take off the skates, which provides great benefits not only to the user but also to the seller. Additionally, the skates are relatively lightweight, the same skate can be used for both shoes, and the manufacturing process is simplified, reducing manufacturing costs.
