Description

  The present invention relates to an ice skate shoe blade polishing apparatus for polishing a blade portion of a sliding blade of an ice skate shoe.

  The blade portion of the ice skate shoe has a lock shape so that the blade portion of the ice skate shoe can smoothly bend and slide along the corner of the ice rink run track. The lock shape refers to a generally arc shape in which a central portion in the longitudinal direction of the blade portion is slightly higher than the front and rear portions.

  In sliding, the blade part is changed in the necessary angle direction in plan view with respect to the sliding direction, and the edge part (blade surface corner) of the blade part is pushed to the surface of the ice, and the link is kicked with the hind legs. . In particular, the above operation is frequently used when turning a corner of a planing track.

  For this reason, an edge part is worn by sliding. If the edge portion becomes round, ice cannot be caught at the edge portion, and the driving force decreases. Furthermore, when the edge portion becomes round, it may fall down due to corner sliding when it is severe. In order to prevent a decrease in propulsion force and a fall during corner sliding, it is necessary to frequently perform repair polishing that corners the edge portion of the blade after sliding.

  After sliding, the blade of ice skates is heavily worn at the center and the edges are rounded, so it is difficult to apply uniform force over the entire length of the blade when polishing the blade. In addition, since the contact surface width of the grindstone is small at the center where the edge is rounded, even if the same pressing force of the grindstone is applied, the surface contact pressure at the center increases, and force is applied to the center. There is a tendency that the amount of polishing at the center portion of the blade portion is larger than the amount of polishing at the front and rear portions.

  If such polishing is performed, it will be polished so as to be an arc with a radius of curvature larger than the radius of curvature of the arc that was attached to the blade as a lock shape, and therefore, the lock shape of the blade In some cases, the curvature of the blade was out of order. In this case, naturally, the curve does not turn well, the speed does not come out, and it interferes with the competition. For this reason, it was normal for professional engineers to perform polishing.

  Specialized technicians know that the edge of the ice skate shoe after sliding has a large amount of wear at the center and a rounded edge. Because the contact surface width of the grindstone is small, we are skilled in reducing the pressing force of the grindstone and increasing the pressing force of the grindstone at the front and rear parts of the blade surface, so that the lock shape with almost a predetermined radius of curvature is restored even after polishing. And the edges can be rounded.

  According to a conventional blade polishing apparatus for ice skate shoes, the blade part of a pair of ice skate shoes is set up on the base with the blade parts facing upward and parallel, and the operator holds the apparatus main body with both hands, and a pair of rotating grindstones Is rotated and pressed against the upper surfaces of both blade parts, and accordingly, the guided part of the apparatus main body and the guide part provided on the base are engaged between the shoes, and the guided part and the guide part are engaged. With the help of the guide action, the rotating grindstone is moved along the blade portion to perform blade polishing and to corner the edge portion of the blade portion.

  For example, Patent Literature 1 discloses an ice skate shoe blade polishing apparatus. This polishing apparatus includes a drive unit mounting plate (frame), a pair of electric motors, and a pair of polishing disks. A pair of grinding | polishing discs are accommodated in a pair of notch formed in the lower surface of a drive part attachment plate, and are equipped with the grinding | polishing part in the lower surface. The pair of electric motors is fixed to the upper surface of the drive unit mounting plate, and the rotation shaft thereof is passed through the shaft hole provided in the drive unit mounting plate and further passed through the center hole of the polishing unit, and the nut is screwed together. The polishing disc is fixedly supported. A linear concave portion or convex portion is formed along the center line between the rotation axes on the lower surface of the drive portion mounting plate, and the concave portion or convex portion is guided by guide means provided on the base.

  An operator supports this polishing apparatus with both hands, drives a pair of electric motors in opposite directions, and places a pair of polishing disks rotating in opposite directions, with the blade portion of the sliding blade facing up on the base and Polishing is performed by pressing the blades of one pair of ice skate shoes set in parallel and moving forward or backward in the direction guided by the guide means.

Japanese Utility Model Publication No. 5-70856

  However, the blade polishing apparatus for ice skate shoes described in Patent Document 1 is not configured to be able to regulate the polishing allowance. For this reason, this polishing apparatus breaks the lock shape attached to the center part of the blade part unless a uniform pressing force is applied to the blade part of the pair of ice skates on the left and right and front and rear. There was a risk of polishing. However, it is necessary to have skill to make the abrasive disc uniformly hit the blade part of a pair of ice skate shoes on the left and right and front and rear.

  The present invention has been devised in view of the above-described points, and does not require skill, and the blade for ice skate shoes that can perform polishing for cornering the edge portion of the blade portion without upsetting the lock shape. An object is to provide a polishing apparatus.

  In order to achieve the above object, the blade polishing apparatus for ice skate shoes according to the present invention has a grindstone in close contact with the blade surface of the sliding portion of the ice skating shoe, and slides the grindstone in the longitudinal direction of the blade portion. A blade polishing device for ice skating shoes that polishes the edge portion of the blade portion so as to keep the same lock shape as before according to the blade portion. A template, a blade portion holding means that can be held on the frame with the blade portion facing upward and parallel to the template, and the blade surface of the blade portion held by the blade portion holding means is a template Blade surface height aligning means for aligning with the height corresponding to the upper end surface of the blade, and the blade portion whose blade surface height is aligned by the blade surface height aligning device and sandwiched by the blade portion sandwiching means Against the height Polishing means for polishing the blade surface so that the edge portion has an angle while moving the grindstone prepared in an adjustable manner by following the upper end surface of the template by human power and maintaining the lock shape unchanged from the conventional blade portion, It is provided with.

  According to the present invention, the gantry includes a template whose upper end surface has a lock shape, and blade portion clamping means that can be sandwiched with the blade portion facing upward and parallel to the template. The blade surface height aligning means is placed and fixed on the template, and the blade surface of the blade portion held by the blade portion holding device is brought into contact with the bottom to align the height with the upper end surface of the template. The blade surface height alignment means is removed, the polishing means is set on the template, the height of the grindstone is adjusted, and the necessary polishing allowance is set. The polishing means is stably held in the left and right direction by a plurality of rollers that are in contact with the template and roll. The polishing means is the same as the lock shape of an ice skate that requires template polishing, and is necessary for attaching an edge. The grinding allowance is accurately given to the grindstone, and the blade is polished back and forth along the template.

  According to the above configuration, even if non-uniform human power is applied to the polishing means that moves following the upper end surface of the template, the posture is restricted by the template and the polishing allowance is restricted, so that the lock shape is impaired. There is no. For this reason, it is possible for a player wearing ice skates to polish the blades of the ice skate shoes in order to correct the slightly worn edge roundness. Can be polished, and always compete in the best ice skates.

  According to the present invention, it is possible to provide an ice skate shoe blade polishing apparatus that can perform polishing that makes a corner of the edge portion of the blade portion without distorting the lock shape without requiring skill.

The upper end surfaces 13a and 14a of the upper and lower surfaces 13 and 14 can be moved while following the lock shape, and the blade surface B1 is polished to the minimum necessary with the grindstones 10 and 11 whose movement path is restricted and the polishing allowance is restricted. Thus, the edge B can be ground while retaining the lock shape that is the same as before.

Next, a method of handling the ice skate shoe blade polishing apparatus 1 having the above-described configuration will be described.
[Frequency fixing procedure]
(1) Mounting of the blade surface height alignment means 16 As shown in FIGS. 2, 3, and 4, the connecting bolts 16b provided at both ends of the bar member 16a are screwed into the screw holes provided in the anvil bar 15a. In combination, the bar member 16a is fixed in a state of being placed on the upper end surfaces 13a, 14a of the templates 13, 14.
(2) A pair of blade portions B and B are inserted between the anvil bar 15a and the pinching bar 15b from below, and further pushed up so that the blade surfaces B1 and B1 of the blade portions B and B are the lower surface of the bar member 16a. Abut. Thus, the blade surfaces B1 and B1 of the blade portions B and B are set at the same height as the upper end surfaces 13a and 14a of the templates 13 and 14.
(3) The clamp 15c is tightened to move the pinching bar 15b in the direction of the anvil bar 15a, and the anvil bar 15a and the pinching bar 15b jointly hold the blade portion B.

Therefore, with the blade B facing upward and parallel to the templates 13 and 14, the blade surfaces B1 and B1 of the blades B and B are set at the same height as the upper end surfaces 13a and 14a of the templates 13 and 14. .
[Polishing procedure]
(1) Setting and Adjustment of Polishing Allowance As shown in FIGS. 5, 6, and 7, the polishing allowance is set and adjusted by turning the adjusting screw 171 of the grindstone height adjusting mechanism 17 a to adjust the height of the grindstones 10 and 11. Adjust the height. The adjusting screw 171 is rotated so that the grindstones 10 and 11 are in contact with the blade portions B and B of the ice skate shoes set at the same height with respect to the templates 13 and 14. At this stage, since the polishing allowance is zero, the adjustment screw 171 is further rotated and the lock bolt 172 is tightened so that a necessary amount of polishing allowance is obtained.
(2) Removal of blade surface height alignment means 16 The connection between the bar member 16a and the anvil bar 15a by the connection bolt 16b is released, and the blade surface height alignment means 16 is removed.
(3) Polishing The holder frame 17e of the polishing means 17 is gripped and reciprocated. Then, since the rollers 17c and 17d roll back and forth on each template 13 or 14, the grindstones 10 and 11 are moved following the templates 13 and 14, respectively. As a result, the ice skate shoe blade polishing apparatus 1 causes the grindstones 10 and 11 to adhere to the blade surface B1 of the blade part B of the sliding blade A of the ice skate shoe, and the grindstones 10 and 11 are slid in the longitudinal direction of the blade part B. The edge part of the blade part B can be made to move, and it can grind | polish so that the same lock shape as before may be hold | maintained.

  In the above configuration, the reason why the pair of templates 13 and 14 are provided in a state of being spaced apart in parallel at a predetermined interval is that when the grindstones 10 and 11 are brought into close contact with the blade portions B and B of a pair of ice skates, the blade portion This is because it is necessary to stabilize the polishing surface of the grindstone with respect to a horizontal plane along a horizontal direction orthogonal to the longitudinal direction of B and B. In addition, the reason why the two rollers 17c and 17d that roll on the templates 13 and 14 on the front and back are provided is that the horizontal plane along the length direction of the blade portion B needs to be stabilized during polishing. It is.

  For this reason, the four rollers arranged in the left / right front / rear direction maintain the left / right stability of the grinding wheel cost and the stability in the front / rear direction, and the grindstones 10 and 11 are stable even if a non-uniform external force is applied. Can be polished. Since the holder frame 17e does not drop more than the two rollers 17c and 17d attached are regulated by the templates 13 and 14, a stable posture is ensured even if the force is applied unevenly, and the grindstone 10 , 11 does not grind the blade parts B, B of the ice skate shoe more than necessary.

  According to the said structure, the grindstones 10 and 11 are correctly made into the lock shape of a rail surface by arrange | positioning the blade part B and a template in the vicinity, and making the height correspond and using the lock shape of the rail surface of the templates 13 and 14 as a guide. Since it can be made to reciprocate, it can be polished to transfer the lock shape of the rail surface to the blade part B, it can always be polished to the best lock shape without deviation and sharp at the edge part Polishing to revive the corners can be performed. For this reason, the blade part B of the ice skate shoe is not damaged, and skill is not required, and the edge part of the blade part B can be ground without changing the lock shape.

  According to the said structure, after setting the blade parts B and B of one pair of ice skate shoes according to the templates 13 and 14, the grinding allowance of the blade part B can be set. Therefore, it is possible to avoid grinding the blade part B more than necessary, and it is possible to make a right angle to the edge of the blade part B in a short time without impairing the radius of curvature of the lock shape. For example, it can be polished at every competition, and you can always skate in the best condition with sharp edges revived at the edges. Furthermore, since it can avoid grind | polishing more than necessary, the height of the blade part B does not change a lot, and an ice skate can be used for a long time.

Furthermore, according to the above configuration, when the blade portion B is polished, the blade portions B and B can be set apart so that the pair of ice skates do not interfere with each other. Since a large space is provided and the templates 13 and 14 are provided using this space, it is possible to enhance the function while being accommodated in substantially the same form as the external dimensions of an existing commercially available polishing machine. According to the said structure, when adjusting the grinding | polishing allowance of a grindstone in order to prevent that the grinding | polishing surface of a circular grindstone is worn out, it is preferable to use the circular grinding | polishing surface using the position little by little.
