Description

Technical Field

[0001] The utility model relates to a sports equipment which has both high-speed roller skating and high-bounce functions. Background Art

[0002] In addition to the gliding function, roller skates have undergone various changes. Among these roller skating device change schemes, there are those that focus on function switching, such as the schemes with application numbers CN92234778, CN92211512, CN85204533, CN202110574083, CN201720991942, CN201720957475, CN201720885722, CN200920041426, CN200920041427, and CN98236265, which realize the switching between ordinary shoes walking and roller skating functions; there are also those that focus on converting up and down pedaling force into forward power, such as application numbers GB0427485A, RU2004112279A, US19990336273A, and US19780895 511A, US19370172564A, US19320610956A, US19120708953A, US19090496193A, US19090489958A, GB190623500DA, US19050284388A, 201820868696, 201920312327; there are also those focusing on shock absorption, such as application numbers 202111101896, 202121256113, 202220306319, RO201500698A, WO2007EP04782, FR0512448A, US19980017272A, US19080452488A. Some people also want to add a bouncing function to roller skates. For example, the solution with application number 202111282562 is to add multiple small wheels under the sole and two arc-shaped springs on both sides of the shoe. When the arc-shaped springs are turned up, they become roller skates, and when they are turned down, they become spring-loaded. The disadvantages are: 1) The roller skating function is very weak because the wheels are too small; 2) The bouncing function is useless, you can't jump high, and you can't use the roller skating function when using the bouncing function, which is not fun to use. Another example is the solution with application number 202122143133, which installs the springs between the lower row of wheels and the sole. Its disadvantages are still 1) It can't jump high, because the design of the bow-shaped spring is destined to have a very limited bounce stroke; 2) It can't slide fast because the wheels are too small. The solution with application number US20000562759A focuses on the bouncing function, but its disadvantages are: 1) the center of gravity moves left and right when squatting and bouncing, which greatly increases the difficulty of controlling limb balance; 2) the wheels are too small and cannot slide fast. The solutions with application numbers CN200620096639 and 201720402711 also have similar disadvantages, either they cannot jump high or they cannot slide fast.

[0003] At present, there is a need for a roller skate with high bounce ability, high speed sliding ability, high shock absorption ability, high safety, easy operation, high playability, and strong and durable. The following is my solution, which meets all these expectations. Summary of the invention

[0004] The high-bounce high-speed giant roller skates include a cross-wheel system A, an upper plate system B, a leg-foot support system C, and a brake system D. The cross-wheel system A is responsible for the function of sliding and bouncing on the ground. The upper plate system B is the basic platform of the entire roller skates. This platform connects the cross-wheel system A, the leg-foot support system C, and the brake system D into an organic whole. The upper plate system B is located above the cross-wheel system A, and the leg-foot support system C is located above the upper plate system B. The leg-foot support system C allows the roller skaters to comfortably complete the actions of standing, sliding, bouncing, etc. Another outstanding advantage is that it can well prevent the roller skaters from spraining their feet. Since the wheels of roller skates are large, the sliding speed is fast, and there is a high bounce function, the brake system D is designed to improve the safety of roller skates. It is a soft rope handbrake system, including brake disc D01, wire sleeve D04, brake rope D11, handbrake box D05 and other components. The brake rope D11 connects these components. The wire sleeve D04 is the supporting shell and auxiliary actuator of the brake rope D11, which respectively connects the outer fork frame A02, the upper plate system B, the skater's calf, thigh, torso, upper arm, lower arm, and handbrake box D05, allowing the skater to move freely while completing the braking function.

[0005] High-bounce high-speed giant roller skates have the advantages of high speed, good shock absorption, high bounce ability, high safety and comfortable use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0008] Note: To facilitate description in various occasions, the full name of the item in this article, "high-bounce high-speed giant roller skates" and the abbreviation "roller skates" and "giant roller skates" are interchangeable and refer to the same thing. "Front and back", "left and right", and "up and down" are based on the visual direction of the reader facing the attached figure currently under discussion.

[0009] like Figure 6, a high-bounce high-speed giant roller skate, comprising a cross-wheel system A and an upper plate system B; the cross-wheel system A comprises an inner fork frame A01, an outer fork frame A02 and a central pivot axis A03, the middle of the inner fork frame A01 and the outer fork frame A02 are pivotally connected together through the central pivot axis A03; the lower end of each of the inner fork frames A01 and A02 has a giant wheel A05, and the upper end has a spring shaft A10, and at least one main shaft A10 is connected between the two spring shafts A10. Spring A11, the tension of the main spring A11 has a tendency to drive the inner fork frame A01 and the outer fork frame A02 to close inward with the central axis A03 as the center; the upper ends of the inner fork frame A01 and the outer fork frame A02 each have an upper end axis A06, the middle of the center line connecting the two upper end axes A06 has a center axis A08, the center axis A08 and the upper midpoints of the inner fork frame A01 and the outer fork frame A02 are each connected to a center connecting rod A09, The length of the center connecting rod A09 is equal to half the length from the central axis A03 to the upper end axis A06; the upper flat plate system B includes a flat plate box B01, and there is a center hole B03 in the middle of the two side surfaces of the flat plate box B01, and two side slot holes B02 are symmetrically distributed on the left and right sides of the center hole B03; the center axis A08 can be pivotally inserted into the center hole B03, and the two upper end axes A06 are respectively inserted into the side slot holes B02 and can slide left and right within the range of the slot holes; the change in the vertical distance between the flat plate box B01 and the giant wheel A05 corresponds to the change in the horizontal distance between the two giant wheels A05, and also corresponds to the change in the length and tension of the main spring A11; no matter how the shape changes, the plane where the axis of the two giant wheels A05 is located is always parallel to the upper surface of the flat plate box B01, and the axis of the two giant wheels A05 is always symmetrical about the left and right center planes of the flat plate box B01.

[0010] Furthermore, if Figure 4 , 5, 6, each giant wheel A05 is installed on an eccentric shaft A04; the directions of the two eccentric shafts A04 are opposite, so that the two giant wheels A05 are distributed on both sides of the front and rear center planes of the inner fork frame A01 and the outer fork frame A02, so that the distance between the two giant wheels A05 has a larger variable range and the roller skates have a smaller folded volume.

[0011] Furthermore, if Figure 5 , 6, 7, each of the upper shafts A06 has two rollers A07, the two rollers A07 are in close contact with the lower surface of the flat box B01 and can roll along the lower surface; the two rollers A07 are distributed on both sides of the front and rear center planes of the flat box B01.

[0012] Furthermore, if Figure 5, 6, 7, the lower surface of the flat box B01 also has a baffle screw B05 with opposite threads at both ends, and the axis of the baffle screw B05 is located on the front and rear center axis planes of the flat box B01; three screw slide rings B04 are fixed at the left, middle and right positions of the lower surface of the flat box B01 to fix the baffle screw B05; the baffle screw B05 is sleeved with two baffles B08, and the two baffles B08 are symmetrically distributed on both sides of the left and right center planes of the flat box B01; One end of the baffle screw B05 is provided with a hexagonal recessed hole B06; one end of the flat box B01 is provided with a tool hole B07 at a position opposite to the hexagonal recessed hole B06, and a common tool hexagonal screw rod of suitable size can be inserted into the hexagonal recessed hole B06 from the tool hole B06. Turning the hexagonal screw rod can adjust the distance between the baffles B08, thereby adjusting the telescopic range of the main spring A11 and then adjusting the distance range between the giant wheels A05, thereby also adjusting the height range that the roller skates can jump.

[0013] Furthermore, if Figure 8 The roller skates also include a leg and foot support system C; the leg and foot support system C includes a pedal C01, a stop plate C02, a lower extension plate C03, a pedal shaft hole C04, a foot slot hole C05, a tilt foot spring C06, a lower support frame C07, a strap frame C08, a strap hole C09, and a locking bolt C10; the pedal box B01 also includes an upper extension plate B09 and a pedal shaft B10; the pedal shaft B10 is locked and rotated with the pedal shaft hole C04 on the upper extension plate C03, thereby pivotally connecting the leg and foot support system C and the upper plate system B as a whole; the strap frame C08 can be rotated along The two branch pipes of the lower support frame C07 extend deeper or shallower, and the locking bolt C10 can lock the binding frame C08 at a required height so that people with different leg lengths can obtain suitable calf support; the lower support frame C07 can move along the foot slot hole C05 and be locked at a required position so that the shoes of roller skaters with different foot widths can obtain an ideal standing position; the foot tilting spring C06 can enable the roller skater to obtain horizontal sole support when the body is upright, and can allow the roller skater's calf to tilt forward to complete the leg bending action when the roller skates are pushed backward diagonally to obtain forward momentum or when squatting down to store energy for jumping.

[0014] Furthermore, if Figure 1, 2, 6, 9, 10, 11, the roller skates also include a brake system D; the brake system D includes a brake disc D01, a caliper box D02, a pipe clamp D03, a wire sleeve D04, a handbrake box D05, a fixed pinch rod D07, a dynamic pinch rod D08, a traction groove D06, a wire binding ring D09, a steering ring D10, a brake rope D11, a caliper D12, and a caliper spring D13; the two ends of the brake rope D11 are connected to the caliper D12 and the wire binding ring D09 of the dynamic pinch rod D08, and pass through the steering ring D10; most of the brake rope D11 passes through the wire sleeve D04 The two ends of the wire sleeve D04 are fixed by the pipe clamps D03 located on the outer fork frame A02, the flat box B01, and the handbrake box D05, and the middle part is fixed by the straps on the legs, body, and arms of the roller skater. Its bending state changes with the change of the body shape of the roller skater, but it can always transmit the grip of the roller skater's hand to the caliper D12 through the brake rope D11. The brake rope D11, the caliper D12 and the caliper spring D13 jointly complete the action of clamping and releasing the brake disc D01, thereby completing the function of deceleration, stopping or normal sliding of the roller skates.

[0015] The method of using the high-bounce high-speed giant roller skates is that the roller skater can stand upright or bend his legs when skating; when the roller skates push the ground to gain forward momentum by pushing the legs backward obliquely, the rear wheels of the roller skates can be lifted or not; when the roller skates need to be jumped, the roller skater bends his legs and squats at a relatively high speed to press down the roller skates, at which time the main spring A11 is stretched and accumulates potential energy, and then the main spring A11 will contract, and when the roller skater quickly straightens his legs, the reverse thrust of the ground will push the roller skates and the roller skater into the air; the larger the active stroke of the main spring A11 is adjusted, the greater the range of the roller skater's squatting, the faster the legs are straightened when jumping, and the higher the jumping height.

[0016] Advantages of high bounce high speed giant roller skates: Extremely high jumping ability. The design of the cross frame A01, A02 provides a large contraction and expansion stroke for the main spring A11 and the giant wheel A05, which can store more energy when the roller skates are pressed down, and this energy can be released softly, so the conversion rate of its conversion into bouncing energy is very high, so that it can easily jump many times higher than ordinary roller skates, generally reaching 2 to 5 meters.

[0017] Excellent shock absorption capability. Firstly, the diameter of the giant wheel A05 is very large, reaching about 300 mm, which has good passability on uneven roads, ditches, edges, etc.; secondly, the expansion and contraction of the main spring A11 will also eliminate most of the vibration or impact of the road surface, so the high-bounce and high-speed giant roller skates have a shock absorption capability far exceeding that of ordinary roller skates.

[0018] Faster skating speed. Thanks to the two giant wheels A05, the skating speed of giant roller skates is much faster than that of ordinary roller skates with the same physical effort.

[0019] Higher safety. The leg support system C can effectively prevent sprains, and the addition of the brake system D allows skaters to slow down or stop at any time. In addition, the roller skates always maintain the central symmetry, which greatly improves the safety of roller skating.

[0020] Excellent controllability. The existence of the center axis and the center connecting rod makes the center of gravity of the human body always in the center of the roller skates, and the two giant wheels are always symmetrically located on both sides of the center axis, which makes it easy for people to grasp the center of gravity of the entire system at all times and to perform various roller skating actions easily.

[0021] The adjustment is simple. You only need to insert a common hexagonal screw rod from one end of the flat box and turn it to adjust the extension range of the main spring, thereby adjusting the bounce height and the minimum wheelbase, so that a pair of roller skates can meet the needs of the entire process from beginners to roller skating masters, and become a good partner to accompany them in their growth.

[0022] Strong and durable. Due to the fork-scissor structure with constant symmetry and the structure in which the upper plate is always parallel to the ground, the force distribution of the whole system is uniform and gentle, and no parts are subjected to severe torsion or impact force, so the wear or fatigue of its parts is very light. In addition, the large parts of the roller skates can be made of materials such as aluminum alloy or carbon fiber, so the weight of the roller skates can be controlled within a small range while the entire roller skates can still achieve high strength.

[0023] The materials and dimensions of the parts used in this article are the author's ideal designs and are only examples. They should not be considered as limiting factors for the technical features. The technical features of this design should be determined by the claims.
