Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a single or multi-piece ice skate guard having a groove for removably holding an ice skate blade.

A large number of skate guards have been developed and used, and their designs vary for several different types of skate blades. One example of a conventional guard consists of an elastic rubber body, with a groove closed at both ends by substantially vertical walls. The skate blade is removably retained within the groove by pressing both ends of the blade against the wall by the elasticity of the rubber material.

This modified type of guard is made of non-resilient material and lacks a nearly vertical back wall, instead
It has an elastic loop. This elastic loop is operated to surround the skate blade at the rear of the rear post that connects the blade to the skate, and the guard is advanced by the action of the loop, with the nearly vertical front wall holding the tip of the blade. be promoted to do so.

A similar guard consists of a wooden block with a receiving groove. A yoke at the front end of this block prevents the blade from moving forward or upward. The rear end of the blade is prevented from moving upward in relation to the block by a spring-loaded clamp. This clamp is attached to the block approximately in its longitudinal center and is pivotable into the clamping position so as to partially encircle the upper enlargement of the blade between the two pillars connecting the blade to the shoe. It's getting old.

The above guards and other known guards have the following disadvantages. A disadvantage common to all is that the elastic member or clamping member of the guard, such as the loop, breaks down after repeated use. Another disadvantage is that the same guard cannot be used for skate blades of different shapes or blade-to-shoe connections. Still other disadvantages are that each guard can only be used on very limited skate sizes and does not securely secure to the skate under heavy pressure.

SUMMARY OF THE INVENTION An object of the present invention is to provide an ice skating guard that eliminates the above drawbacks. This object is achieved by the features specified in the claims.

The greatest advantage of this invention is that the guard remains firmly on the skate even under heavy pressure, for example. It is also easy to install and remove, is strong and durable, and allows the same guard to be used with a number of different skate sizes.
Another advantage is that it can be used even when the shape of the blade or the shape of the connecting member between the blade and the shoe is different. Further advantages will become apparent from the description below.

As shown in FIGS. 1 and 2, the ice skating guard of the present invention in its most preferred embodiment has a main body composed of two members. That is, front part 1
and rear portion 2, each of which is integrally molded from a hard plastic material. The rear part 2 has a back wall 3 that slopes upwardly and forwardly, and prevents the skate blade 4 shown in dashed lines from moving rearwardly and upwardly from the groove. The grooves consist of a relatively short groove 5 that opens upward and is formed in the thick rear part of the rear part 2, and a relatively long groove 6 that opens upward and is formed in the front part 1. It's on the line. The back wall 3 is relatively high so that the guard can be stably held on the blade 4.

The rear portion 2 has a parallel trapezoidal cross-sectional shape with a short parallel upper side open. The rear part of front part 1 is
It has a corresponding cross section and is fitted into the rear part 2, and the back wall 3
The position is variable in the insertion/extraction direction so that the distance between the front end portion of the front portion 1 and the front end portion of the front portion 1 can be shortened or extended.
Therefore, the guard can be adjusted according to the desired length of the skate blade. The trapezoidal cross-sections of the front part 1 and the rear part 2 make it impossible to remove the front part 1 other than by pulling it out from the rear part 2 in the insertion/removal direction. front part 1
and rear portion 2 can be fixed to each other in any of a plurality of desired positions. Therefore, a plurality of holes 7 are formed in both walls of the front part 1, and four slits 8 are formed in both walls of the front part 1.
are formed on both walls of the rear part 2. The slit is formed on the same level as the hole 7. After setting the desired guard length, four screws 9 are inserted through the slits 8 and screwed into the holes 7. The short adjacency distance of the holes 7 and the length of the slits make it possible to adjust the type. After screwing, the front part 1 is securely fixed to the rear part 2.

The front end of the front part 1 has an inclined front upward curved surface 10.
on which there is a roughly S-shaped tongue piece 1 made of a flexible and wear-resistant plastic material.
One leg 11 of 2 is attached by screwing or other method. The legs 11 are relatively long and extend to the lower part of the front part 1 to securely attach the tongue 12. The leg 11 has an intermediate portion 1 that bulges out in two rear directions.
3, the free leg 14 extends forward beyond the toe T of the ice skate.

Anti-slip members 15 and 16 are attached to the bottom surface of the leg 11 and the rear bottom surface of the rear portion 2. These increase the friction between the guard and the ground when the skater walks with the guard on the skate.

When attaching the guard to the skate, place the guard on the ground with the groove facing upward, insert the rear part of the skate blade 4 into the groove 5, and press it toward the back wall 3. 1st
This is shown by the dashed line in the figure. Then, the curved cutting edge S at the front of the blade is pushed down from the position shown in FIG. 1 to engage with the tongue piece 12. Middle part 1
3 and the free leg 14, the cutting edge part S of the blade 4 is the intermediate part 13
, the intermediate part 13 is pushed forward by the spring action of the plastic until it comes into contact with the rear ascending slope of the member 17 connecting the blade 4 and the skate. Once the cutting edge portion passes through the intermediate portion 13, the blade 4 fits into the grooves 5 and 6 and is held in position by the tongue piece 12 engaged with the connecting member 17.

In the fitted state of the guard, the bottom surface of the connecting member 17 on either side of the blade 4 is located on the upper surface of the front part 1 and the rear part 2 with the grooves 6 and 5. This is because the height of the blade 4, ie the vertical distance from the edge of the blade to the bottom surface of the connecting member 17, is less than the depth of the grooves 5 and 6. In this way, the sharp edge of the blade can be prevented from coming into contact with the bottom of the groove and causing wear. In order to facilitate positioning when inserting into the groove 6, a guide member for holding the blade at the center of the tongue 12 may be provided on the upper surface of the tongue between the intermediate portion 13 and the free leg 14.

To remove the guard, push the intermediate section 13 forward, e.g. by pressing a finger or an ice hook stick onto the upper side of the free leg 14, and remove the front end of the blade 4 and then the entire blade from the guard. This can be done by lifting it up.

Although only one embodiment of the invention has been described and illustrated, the invention is not limited to the embodiment described above, but rather by the scope of the claims.

That is, in the above example, the main body having the groove of the ice skate blade is composed of two members that can be inserted into and removed from each other in the longitudinal direction, but it may also be formed as a single main body, and it can be formed by combining a flexible tongue piece. The purpose of reliable attachment and easy removal can be achieved by the combination.
