    An ice skate having a metal blade with the upper edge thereof embedded in the lower portion of the body of the skate which is made of plastic material. Plastic material integral with the body of the skate extends through longitudinally directed through-holes in the upper edge of the blade. There are at least three through-holes, including a centrally disposed centering through-hole which is entirely filled with plastic material integral with the material of the skate body. The other through-holes, located respectively forwardly and rearwardly of the centering through-holes, are only partially filled with plastic material integral with the body of the skate, the ends of the other through-holes which lie nearer the central through-hole being empty whereby to allow longitudinal shifting of the molded plastic body of the skate as it cools and hardens after having been injection-molded about the upper edge of the skate blade. The minimum dimensions of the spaces within said forward and rear through-holes are determined by the shrinkage of the plastic material, and by the distance of said additional through-holes from the centrally located, centering through-hole.

    专利说明:

    The invention relates to a ridge with a plastic support body in which the expansion of the plastic is taken into account.
    The reinforcement of the knife in plastic in known skates is made so that the holes s of the upper part of the knife of the ridge are sprayed with the same plastic that forms the supporting part of the ridge, where from the upper side of the knife embedded in plastic the reinforcing protrusions protrude in the direction of the plastic case. These holes in the upper part of the knife are through or in the form of recesses. In these skates, DO does not take into account the thermal expansion of the plastic. When plastics shrink, plastics are most susceptible to the surface of mutual contact between plastics and a metal skate knife. If in critical places not
    the space for expansion of the plastic is determined, then a mechanical breakdown of the plastic will occur, and cracking is possible. Manufacturers solve this drawback in a different way. For example, to strengthen the joint between the knife and the plastic, it uses a hollow rivet or a hole with a flange, and the diameter of the holes in the knife is a percentage of the expansion of the plastic larger than the external diameter of the rivet or hole with a flange. On the outer side between the rivet and the knife there is a gap covered by a flange. During the molding operation, the plastic flows into the cavity inside the hole or hollow rivet, as a result of which the steel knife interconnects with the plastic ridge body. Flange prevents plastic flow between outer diameter

    riveting and opening knife housing. Upon completion of the molding operation, the plastic is cooled and settles in the bridge most :. i zlgrulki with a gap between the diameter of 5;, ziklepki rum and a hole, which prevents mechanical disturbance of the plastic support body. The ridge is not centered, consequently, it may happen that the blade moves the knife relative to the plastic.
    A ridge and a method for its manufacture are known, according to which a rod is inserted into a through-hole in the knife in front of the plastic. After the plastic has hardened, the rod is reinforced and the joint is reinforced with a rivet with a smaller diameter than the hole that has arisen in the knife. It is possible to plug only the hole in the knife and, after the plastic has hardened, drill a hole for the rivet and plastic. The use of a rivet or a flanged hole is laborious and does not preclude the expansion of the plastic, and thus the undesirable displacement of the knife in the transverse direction, i.e. in the direction of the edge of the knife, protruding from plastic, which comes in contact with ice.
    The solutions of the ridge described above, with the removal of mechanical damage to the plastic case under the influence of thermal expansion, proceeded from a flat, undissolved upper part of the knife, which is filled with plastic.
    Known friend of the shape of the knife shape skate. The knife does not have an equal upper surface. In the middle part approximately 2/3 of the upper surface of the knife is cut longitudinally, the cut on both sides touches the end parts of the knife, the upper surface of which remains uncut, and in the axis of the knife there is a protrusion with a center through from. This solution allows the plastic to expand towards the center of the ridge and protects the plastic from damage, but this is due to the deterioration in the strength of the blade fastening in the plastic mass of the support.
    These drawbacks are eliminated by the ridge according to the invention, the essence of which lies in the fact that along the upper edge of the knife there are at least two lateral side holes and a center through hole, the filling of which is the same as the plastic supporting body, and the lateral through holes of the mouth have its edges directed towards the center through hole, the expansion gap.
    By partially filling the through-holes of the ridge knife, unfilled spaces form on the inner side of the apertures, which
    allow expansion. plastics only in longitudinal correction. The through holes are filled with plastic to such an extent that they provide sufficient strength for fixing the ridge to the support
    0 plastic parts. Against the longitudinal displacement, the knife is fixed by a center hole, completely filled with plastic. Solving the problem of plastic expansion at the ridge with the bearing and
    5 plastics are very simple and minimally time consuming in serial production.
    Figure 1 shows a skate knife; figure 2 - the ridge, a partial transverse section; on fig.Z - section aa in figure 2. .
    The ridge with a plastic base part consists of a knife of the ridge 1 and a support body 2 of plastic, which protrudes from the upper part of the knife 1 of the ridge. Excess
    5 of the supporting body 2 of the plastic of the knife 1 is determined by the aesthetic requirements for the skates; in this particular embodiment, this excess is greatest in the central part of the knife and it decreases
    0 to the ends of the knife 1 skate. The knife 1 of the ridge has an equal upper edge 3. The lower edge 4 of the knife 1 has the shape of a curve and at both ends passes into the arcs 5 directed to the upper edge 3 of the knife 1. Along the upper edge
    5 3 knives 1 are arranged through holes 6 and 7, for example, in the form of an oval. These through holes 6. 7 should not be located in the same plane, but the lateral through holes 7 can be placed closer to the upper edge 3 of the knife 1. The vertical arrangement of the through holes 6 and 7 is determined by the length of the excess of the support body 2 made of plastic from the upper edge 3 knife 1. through holes should
    5 be at least three. The center hole b is located in the transverse axis of the knife 1. The upper edge 3 of the knife 1 is molded into plastic, which forms the supporting body 2 of the ridge and the same plastic is formed
    0 through holes 6 and 7. Thus, the support body 2 of the ridge together with the knife 1 is integral. Center hole 6 is completely filled with the specified plastic. Side through holes 7
    5 only partially filled with plastic. At their edges, directed toward the center-Oomus hole 6., expansion spaces 8 are formed, the minimum dimensions of which are determined by the shrinkage of the plastic and extensions from the center through
    holes 6. This space 8 extensions for aesthetic reasons can be masked from the sides.
    As with okspz :: lg: nii plastics - subsequent fzz1 after the plastic has been peeled off and hardened, so with temperature changes during the operation of the ridge in the unfilled protrusion the plastics in the longitudinal direction: “i. Fully filled center hole §. contributes to the strong fastening of the knife 1 in the aforementioned part 2 of plastic / and fixes the knife against longitudinal displacement.
    The offered skates can be used both with hockey and in figure skating.
