| 1. | Designation: Kvick Skate Claim 1 A. Feathering underskate for ice skates. B. All movable underskate for skates in plastic/composite material and more, with flexibility updownwards together with twisting/tilting shown in figure 1. (1) (2.) shows adapted under skate that is either casted in one or same part figure 3. (17) Alternatively push/click mounted with adapted profiles figure 2 (4) that will lock/clamp the parts 1 and 2 together. |
| 2. | Adapted skate strips Figure 1 (3) is clicked in place in adapted profile. Crosssectional drawing Figure. |
| 3. | (1) Flexible strips holder Figure 2 (1) and skate strips Figure 2 (3). For increased speed/friction advantages due to flexible steel strips Figure 2 (3) that is clicked ion place in adapted profile Figure 3 (Ib and Ic) for all types of skates. When skating the underskate is flatting of/flexing showed by Figure 3 (Ia) due to obliquely squareshaped profiles when all pressure/force is on one leg. Figure 3 (Ib and Ic) will flex up or downwards by the means of constringent gas/air parts 4, or alternatively spring profiles Figure 3 (5a and 5b) by increased pressure from the skater (all weight on one leg), also advantageous twisting Figure 3 (2a, 2b and 2c) for more and longer sliding surface in the longitudinal direction and in turns without restraining the turning abilities, and gives friction advantages and increased speed. The skater can also vary the turning technique by transmitting all his weight to the front or rear on the skate, the skate will then decrease the turning radius due to air/gas parts (eventual feathering all, feathering/spring profiles Ia and Ib) that will contract Figure 4 (7a and 7b). With equal pressure on both legs the skate will feather back to normal turning radius, Figure 4 (2) alternatively sliding surface Figure 4 (3) for example hockey skates (app. 46 cm). If the skater desires it the skate can have 100% moment Figure 4 (4) at the kickoff (toe joint). Adjust the adapted brick 5 up/down stiffens it up by kg whish from skater. Movability/flex designed in plastic/composite and the like makes it possible to turn easily, hereunder to crossplace the skate with and without speed, also with large contact surface on the ice. As known, longer sliding surface gives considerably higher speed due to weight distribution over larger area due to friction advantages. When the skater cut's over in a turn at high speed the skates rear and front part will flex/twist Figure 4 (2a, 2b and 2c) to normal turning radius Figure 3 together with the body without problems. Even in the sharpest turns without loosing speed due to large steel surface on the ice that turns together with the body's movement. For adaptation to speed skating (longer skate) the construction can alternatively be stretched out Figure 4 (6a and 6b). Gas/air parts can be replaced with bendable plastic and the like Figure 3 and the like (5a and 5b). The plastic and the like can also in these two parts be cylindrically shaped (flexing together) Figure 3 (6) to make the construction stronger and save components if necessary. Claim 2 Figure 6 shows the underskate without the gas/air parts alternatively arced plastic profiles that are feathering/springs in the front, rear and from the bottom side. Underskate Figure 6 (1) mounted on the rest of the underskate. An adjustable alternative is sliding brick Figure 5. (Ia and Ib) that is adapted in profile (4a and 4b) that has longitudinal threads (3 a and 3b) and is screwed back and forth with the screw (2a and 2b) is screwed from both ends Figure 5 (2a and 2b) and makes the skate stiffer as preferred. Alternatively the distance in the front and rear can have different distance that way the skate will press forward and the rear more together. Or the distance can be increased figure 5 (5) and increases or decreases the radius on the skate as preferred. To adjust the flexibility is done by Figure 5 this is a screw 1 that can be screwed back and forth in the adapted profile (3 a and 3b). Screwdriver is placed in the adapted hole with threads in the front or rear. 4a and 4b shows only the extra material thickness that is fixed in the rail section 3 a and 3b. Figure 6 shows the underskate without gas/air parts, alternatively arced/movable parts in the open parts in front and rear figure 6 (2a and 2b). The strips holder figure 6 (1) is showed mounted here without strips. |
2. Area Of Application: Under-skate for use on all types of skates
3. Technique That The Invention Is Based On: Cited publications raised under the investigation shows no friction advantages to any great extent, due to fixed/partly steel solution that anyhow must be delivered/grinded with gliding surface in the middle part and early rounding upwards in both ends of the skate. As an alternative a radius grind can be used, this means that it is grinded a fixed radius under the whole skate steel. Both alternatives is to make the skate easy maneuverable in turns, but looses considerably speed due to short gliding surface. (Increased pressure on short surface)
4. What Is Particularly Gained By The State Of This Technique: The under-skates frame construction and description (slanting quadrangle, round profiles/air parts, "feathering" construction/mass) distributes the weight on a longer stroke due to feathering when used on hard foundation (ice). When the under-skate feathers/flatens out and gives a longer sliding surface by increased pressure (all weight on one leg) you will obtain friction benefits, increased speed due to more contact with the foundation (is) without restraining the turning abilieties. The skate will follow the skater's movements, also in turn irrespective of radius due to the movable middle, front, and rear part. The under-skate at sudden stop by cross placing the skate will always give after in the rear and front end, this happens due to more flexibility in the ends than the middle part of the skate were it has a moment e.g. 1.5mm, from the toe joint foothold that has 100% moment (due to the kick- off). This means that the skate is not falling in more than a given amount of millimeter in the middle part! Example 1 mm. 5. Which Means Necessary To Achieve The Above: Under-skate is build up with flex/movable plastic parts up down, sideways and twisting.
6. Industrial Exploitation Under-skate can be used to all types of skates.
7. Closer Explanation On The Invention Preferably Illustrated With Sign's: The invention is described with drawings and descriptions. Screw 1 shows that if it is screwed out against the ends of the skate in both ends it becomes stiffer. 4a and 4b is only showing the extra material thickness that is fixed in the groove profile 3 a and 3b.
