Description

Cycling training platform and training equipment

Field of the invention —The object of the invention is a training platform for cycling, which comprises support members for leaning on the base, a lower support attached to the support members and an upper support attached to the lower support, where the upper support has attachment members for attachment to the bicycle and which upper support can be tilted with respect to the lower support around an imaginary axis of rotation, and first spring members for applying a force against tilting to the top support. —The object of the invention is also cycling training equipment, which comprises a first training platform for attachment to the front fork of a bicycle and a second training platform for attachment to the rear fork of a bicycle.

The level of technology

Cyclists and fitness enthusiasts who actively practice cycling practice cycling — not only outdoors but also indoors. Many cyclists prefer to use the same or at least a similar bike as when cycling outside instead of a separate exercise bike for indoor training. For indoor training, the bike is attached to the so-called to the training resistance, so that it remains safely in an upright position during training. Although when driving outdoors along the road, the bike mainly moves forward, — when driving, the bike is also subjected to lateral forces in the direction of the bike's progress. These forces are the result of the cyclist's weight being applied alternately to each pedal, the bike tilting laterally as the cyclist's position and center of gravity change during cycling, and the handlebar position changing when turning the bike. Cycling also changes its character — when cycling instead of on a flat surface, either uphill or downhill. Most training

S resistors are rigidly attached to the bike, so they do not allow the bike to tilt and/or move sideways during cycling. Rigid mounting of the wheel exer-

The resistance to movement puts a strain on the wheel's structures, especially in the vicinity of the attachment points

EO and makes cycling training feel unnatural.

I s 30 — Publication US 10933291 B2 describes a bicycle training resistance, which comprises a front support to which the front fork of the bicycle is attached and a rear support to which the rear fork of the bicycle is attached. The front fork attached to the front support can be moved along the length of the bike

in the Q direction and in the transverse direction. The transverse movement of the front fork causes the frame of the bike to tilt laterally.

In the publication US 10974118 B2, a bicycle training resistance is described, which comprises a lower level placed against the base and an upper level above the lower level. The bicycle is immovably supported on the upper platform. The upper level can be moved relative to the lower level in the longitudinal direction of the bicycle, tilted in the direction transverse to the longitudinal direction and turned so that the longitudinal direction of the bicycle differs from the longitudinal direction of the lower level. There are spring elements between the upper and lower plane, which tend to return the upper plane to a position parallel to the lower plane.

Despite the versatile movement possibilities of the bicycle frame, the bicycle attached to the training resistances according to the publications US 10933291 B2 and US 10974118 B2 still does not produce a riding experience comparable to a free-wheeling bicycle.

The goal of the invention is to bring out a bicycle training platform and training equipment that can reduce problems related to known technology. The goals according to the invention are achieved with the training platform and training equipment, which are characterized by what is presented in the independent patent claims. Some advantageous embodiments of the invention are presented in independent patent claims.

Brief summary of the invention

The subject of the invention is a training platform for cycling, which comprises support members for leaning on the platform, a lower support attached to the support members and an upper support attached to the lower support, where the upper support has attachment members for attaching to the bicycle. The upper support can be tilted with respect to the lower support around an imaginary axis of rotation. In addition, the training platform has the first spring elements for directing the anti-tilting force to the upper support. In the invention, the lower support can be moved relative to the support members in a direction transverse to the direction of the mentioned axis of rotation.

In yet another advantageous embodiment of the training platform according to the invention, the anti-tilting force exerted by the first spring members on the upper support is — adjustable. Advantageously, the distance of the first spring members from the axis of rotation is adjustable. By changing the distance between the spring elements and the axis of rotation, a similar effect on the control of tilting of the top support is achieved as by changing the spring force that resists tilting.

In yet another advantageous embodiment of the training platform according to the invention — the first spring elements are flexible and compressible cushions between the lower support and the upper support.

Detailed description of the invention

Figure 1 shows, by way of example, a cycling training device according to the invention, viewed obliquely from the side. The equipment includes two versions of the training platform, the first of which is attached to the front fork of the bike 102 and the second is attached to the rear fork of the bike 104. The bike attached to the training platforms is preferably a conventional road bike from which the front and rear wheels have been removed to enable attachment to the training platforms. In the first embodiment of the training platform, there is a support frame 40 and an upper support 14 movably attached to the support frame, to which the front fork of the bike is attached. In another embodiment of the training platform, there is a support plate 6, on the upper surface of which is attached a so-called training resistance 30, to which the rear fork of the bike is attached. The training resistance has a gear pack, around which the chain 33 of the wheel is adapted to run. A bike attached to training platforms can be used for cycling training indoors, for example. Pedaling the bike rotates the ring wheel 35 of the training resistance, the rotation of which is resisted by the resistance mechanism belonging to the training resistance, which is not visible in the picture. The working principle of exercise resistance is a generally known technique, so it will not be explained in more detail in this context. — Figure 2a shows the support frame 40 belonging to the first embodiment of the training platform shown in figure 1, depicted from the top angle, and figure 2b shows the top support 14 attached to the support frame, depicted from the front angle. In the following, both images are explained simultaneously. — The support frame comprises two essentially parallel second conductors 42, which have

O 25 — attached first conductor 16 such that the second conductors are substantially perpendicular to the first conductor. The first conductor and the second conductors are essentially identical metal pipes. At each end 2 of the first conductor there is a sliding fastening element 44, through which the second conductor passes through the hole. There is a bearing inside the sliding fastening element, which enables the sliding fastening element and the

D 30 — movement of the first conductor along the second conductor. The bearing in the sliding fastening element 5 can be a sliding bearing, a ball bearing or, for example, by means of plastic rollers

N realized roller bearing. The ends of the first of the second conductors are connected in a corner

The ends of the first support arm 46 are connected to the ends of the first support arm 48 with N push-pieces, and the other ends are connected to the ends of the second support arm 47 with corner connecting pieces. Support legs 28 are hingedly attached to the corner connecting pieces 48. Thanks to the hinge attachment, the support legs can be turned to a passive position in the plane parallel to the first and second conductors or to an active position where the support legs are essentially perpendicular to the direction of the first and second conductors. The support legs can be turned to a passive position, for example when storing the training platform. The support frame forms the support members on which the training platform is supported on a horizontal platform, such as the floor.

Around each second conductor 42 there are two second spring elements 20 in the form of a spiral spring, so that there is one spring element on each side of the sliding fastening element. The second spring element thus rests on its first end on the sliding fastening element 44 and on its other end on the corner joint piece 48. The spring elements, i.e. the spiral springs, — are dimensioned in such a way that in the assembled support frame they are slightly compressed, whereby the spring force of the spring elements tends to keep the sliding fastening elements at the ends of the first conductor in the middle of the length of the other conductors.

An upper support 14 (figure 2b) is attached to the first guide 16 by means of a slide 52, to which the front fork of the bicycle is attached. In the slide, there is a hole through which the first wire 16 passes. Inside the sliding support, there is a bearing similar to the sliding fastening elements, which enables the sliding support to move along the first wire. The sliding bearing can be a sliding bearing, a ball bearing or, for example, a roller bearing made with plastic rollers. Around the first conductor are two second spring members 20 in the form of a spiral spring, so that the sliding support is between the second spring members.

The second spring members are slightly compressed between the sliding fastening member 44 at the end of the first conductor and the sliding support 52, whereby their spring force tends to keep the sliding support 52 in the middle of the length of the first conductor.

The top support attached to the sliding support has a telescopic rod 53, which can be adjusted in length. The rod has two nested tubular parts that can be

N 25 — fasten with a locking screw 50 to each other so that the desired length is obtained for the rod. Tan-

At the first end of N, there are two parallel lugs 54 and connecting them

O plate-like base 55. The lugs are placed on the sides of the sliding support and are connected by sliding

S stitch with pin 56, which passes through the lugs and sliding support. The pin is located on the rod

I 53 for the imaginary central axis. Fastening with the pin and lugs = 30 — enables the rod 53 to tilt around the pin in either direction. Sliding 3 between the substantially flat upper surface 51 and the base 55, there is a gap in which the first two spring members 18 are placed so that the spring members are located in the bar

S to opposite sides of the imaginary central axis. The first spring elements are made of elastic material, preferably neoprene, rubber or silicone — flexible, cylinder-shaped pillows. The compressibility of the first spring members enables limited tilting of the rod around the pin in both directions.

However, the first spring members tend to return the base 55 and the upper surface 51 of the sliding support to a mutually parallel position with their spring force, whereby the rod is in a position perpendicular to the upper surface of the sliding support. In this embodiment of the training platform, the sliding support 52 forms the lower support 12, to which the upper support 14 is attached in an inclined manner around the imaginary axis of rotation passing through the pin 56.

At one end of the bar, there are two end plates on top of each other; first end plate 58 and second end plate 62. The first end plate is immovably attached to the other end of the rod 53 and the second end plate is attached to the first end plate with a bolt 64 parallel to the rod so that the second end plate can wrap around the bolt. At the edges of the second end plate, there are two parallel upper lugs 60, through which the front axle 22 passes, so that the ends of the front axle are placed outside the space defined by the upper lugs. The free ends of the front axle form the first attachment members for attachment to the front fork 102 of the bicycle. The fastening of the second end plate 62 to the first end plate 58, carried out with the help of the bolt 64, enables the Front Fork attached to the front axle to rotate around the bolt, i.e. turning the handlebar of the wheel. A sensor 59 is mounted on the first end plate, which measures the turning angle of the front axle.

On the first side of the upper lugs there is a front bearing 34 and on the other side a rear bearing 36. The front bearing and the rear bearing are essentially the same rod-like parts parallel to the front axle, which are located at a distance from the front axle 22. The front and rear bearing are attached with their own adjusting screws 61 to the plate connecting the upper lugs, thus , that the front suspension and rear suspension can be moved in the direction of the adjustment screw by turning the adjustment screw (in figure 2b, only the front suspension adjustment screw is visible). This leaves an adjustable gap between the front and rear suspension, into which the bicycle's front fork can be fitted. By turning the adjustment screws, the front fork can be adjusted

N for compressions between the front and rear counters. Front response and rear response adjustment screw

The movement in the N vin direction enables a suitable attachment of the front fork, also in the front

S when the tilt angle of the fork changes, for example when changing the length of the rod 53. a The front suspension and the rear suspension form the second fastening elements of the bicycle's front fork.

E 30 — also for attachment. 3 Figure 3a shows, by way of example, another embodiment of the training platform shown in Figure 1, depicted from the top angle and Figure 3b, depicted from the bottom angle.

S This version of the training platform is designed to be attached to the rear fork of a bicycle, in place of the rear wheel detached from the rear fork. In the following, both pictures are explained simultaneously.

The embodiment comprises the support plate 6 shown in figure 1, on the upper surface of which a known exercise resistance is mounted (figure 1). The support plate can be made of plastic, composite material or wooden material, such as plywood. The support plate is attached with screws to the metal intermediate plate 70 below it, each end of which has a mounting projection 72 that turns at a right angle from the plane of the intermediate plate. Between the mounting projections, there is a lower beam 74 formed from a metal profile with a rectangular cross-section. to the mounting projection at the other end of the spacer with the pivot pin 76 so that the lower beam can rotate around the pivot pin. At each end of the lower beam there is a sliding sleeve 45, through which the first conductor 116 passes through the hole. The longitudinal direction of the first conductors is perpendicular to the longitudinal direction of the lower beam. There is a bearing inside the sliding sleeve, which enables the lower beam to move along the first wire. The bearing can be a sliding bearing, a ball bearing or, for example, a roller bearing made with plastic rollers. The free ends of the first conductors have rings 32, which are attached to the first conductors in a bearing manner.

In this embodiment, the rings form support members, on which the training platform is supported on a horizontal platform, such as the floor. The first conductors act as axles, on the ends of which rings are mounted. The lower beam 74 acts as a lower support, which is attached to the intermediate plate 70, which acts as an upper support, so as to turn around the imaginary axis of rotation passing through the hinge pins 76.

Around the first conductors are two second spring members 120 in the form of a spiral spring, so that the sliding sleeve 45 is between the second spring members. The second spring elements are slightly compressed between the ring 32 at the end of the first conductor and the sliding sleeve 45, in which case their spring force tends to hold the sliding sleeve

S 45 and the bottom beam 74 in the middle of the length of the first conductor.

O The lower beam has two plate-like support projections 78 on each side surface. At the same time

S the support projections on the side of the bottom beam are spaced in the lengthwise direction of the bottom beam

I distance from each other and from the ends of the bottom beam. The support protrusions on different sides of the bottom beam point - = 30 — away from the side surface of the bottom beam and are aligned in the length direction of the bottom beam. 3 In connection with the support projections, a plate-like spring support 80 is formed, which has a section above the support projection and a section below the support projection. Above the spring support

The first spring element 118 is on top of the S portion, which is slightly compressed between the spacer plate 70 and the support projection 78. The spring elements tend to keep the intermediate plate 7O of the spring power plant and the support plate attached to it substantially parallel to the imaginary plane passing through the first conductors 116. The first spring element shown in the picture is a cylinder-shaped pillow made of flexible material, such as neoprene, rubber or silicone.

The support projections and the spacer plate 70 have an elongated hole 84 in the longitudinal direction of the support projection (the holes of the support projection are not shown in the pictures). The first spring elements are attached to the upper surface of the upper part of the spring support 80 with a fastening bolt 82 (figure 3b), which passes through the hole 84 in the spacer 70, the first spring element 118, the upper part of the spring support, the hole of the support projection 78 and the lower part of the spring support to the bottom of the spring support. The elongated holes of the spring support and the intermediate plate enable the movement of the spring support and the first spring member attached to it in the longitudinal direction of the elongated hole, whereby the distance of the first spring member from the lower beam 74 and the imaginary pivot axis passing through the hinge pins 76 changes. The change in distance affects the ability of the first spring members to limit the tilting of the spacer plate 70 and the support plate attached to it around the axis of rotation and the ability to return the tilted spacer plate to its original position. When the first spring elements are moved closer to the lower beam, the spring elements limit the tilting of the intermediate plate less, and when the first spring elements are moved further from the lower beam, the spring elements limit the tilting of the intermediate plate more. The user of the training platform can adjust the first spring elements to the desired distance from the intermediate beam by moving the spring supports 80 by hand.

An ordinary bicycle used in road traffic, track cycling or mountain biking can be attached to the cycling training equipment according to the invention. The training equipment works best when a training platform according to the invention is attached to both the front fork and the rear fork of the bicycle instead of the bicycle tires.

The training platforms enable the handlebar to be turned, the bicycle to be tilted sideways, and the bicycle to move slightly sideways, so that — cycling training is very similar to normal cycling. The hardware can be used

N also in such a way that the training platform according to the invention is attached only to either the front or > rear fork. The equipment can be used for cycling training, for example <Q, in such a way that the bike is only attached by its rear fork to the training platform according to the invention. In this case, the front end of the bike rests on the chassis between its own front tire

E 30 — with tyles. Alternatively, the bike can be attached to the training or platform according to the invention only by its front fork, in which case the bike can rest on its rear tire, for example, on a pair of rollers resting on top of the platform.

O The training platform according to the invention to be attached to the front fork of the bicycle can be equipped with fastening elements, with which it can be attached to a surface in a vertical position, such as a wall, or to a rail in a vertical position. A special advantage of the rail attachment is that the distance of the training platform from the horizontal plane can be easily changed, which enables flexible training of uphill and downhill cycling.

Some advantageous embodiments of the training platform and training equipment according to the invention have been described above. The invention is not limited to the solutions explained above, but the inventive idea can be applied in different ways within the limits set by the patent claims.
