Description

Technical Field

[0001] This invention relates to a teaching aid, specifically a modular teaching aid for physical fitness teaching that is easy to assemble and store and can be used in various ways. Background Technology

[0002] During a child's development, various forms of exercise are often used to stimulate their vestibular system and train their core muscles. Vestibular development can improve a child's coordination and concentration. For example, training can be conducted through activities like balance bikes or inline skates that involve speed and muscle exertion. During training, various teaching aids are often set up on the training ground to increase the variety of the activity, such as ramps, hills, or seesaws. Different teaching aids are used to conduct different training sessions and increase the overall variability of the S-shaped training.

[0003] However, most existing teaching aids are made of wood. When they are made, they are mostly assembled and fixed together, meaning that each aid cannot be disassembled or changed after completion. Different aids need to be made and set up individually, and cannot be altered. Therefore, these teaching aids require a large space to accommodate and set up. Furthermore, because wooden teaching aids have a thick base, when the wheels of balance bikes or other equipment come into contact with the aid, the front of the wheel can easily hit the aid, causing it to move due to impact. Prolonged impact may cause it to deviate from its intended position, requiring inspection and adjustment. In addition, after prolonged use, wood is prone to damage or cracking from external impacts, which can easily cause injury to the user. Summary of the Invention

DETAILED DESCRIPTION

[0045] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0046] Please refer to Figures 1 to 3 As shown in the figure, the present application provides a first preferred embodiment of a modular teaching aid 10, which comprises:

[0047] A base plate 20, in this embodiment, is a soft plate body made of EVA material, and the material is not limited, but mainly is a soft and reusable material. The base plate has two flat areas 21 and a functional area 22. In this embodiment, the two flat areas 21 and the functional area 22 of the base plate 20 are each a soft individual, and are sequentially arranged in front and back segments. The front and back ends of the two flat areas 21 are respectively provided with a set of connecting parts 211, and each set of connecting parts 211 is arranged by a plurality of wedge-shaped blocks. The front and back ends of the functional area 22 are also respectively provided with a set of connecting parts 221 at the positions connected with the two flat areas 21, and the two sets of connecting parts 221 are also arranged by a plurality of wedge-shaped blocks. When assembled, the connecting parts 221 at both ends of the functional area 22 are overlapped and connected with the connecting parts 211 at one end of the two flat areas 21, so that the two flat areas 21 are respectively located at the front and back ends of the functional area 22. The two flat areas 21 can also be assembled at one end, such as the front end or the back end, of the functional area 22 by first connecting two adjacent connecting parts 211. After the assembly is completed, the base plate 20 has a set of connecting parts 211 at the front and back ends, which can be used to connect other plates. In addition, the top surface of the functional area 22 is provided with a functional part 222, which is a wave block 223 in this embodiment, and is a plurality of continuous strip-shaped semicircular protrusions (continuous sleepers) 2231 arranged at equal intervals. The functional part 222 of the different functional areas 22 can be made into different shapes or styles according to the needs to produce different terrain changes. When different functional parts 222 are needed, only the functional area 22 with the different functional part 222 needs to be replaced, so that the base plate 20 can produce different changes in the field without replacing the entire base plate 20. The number of flat areas 21 and functional areas 22 of the base plate 20 is only an example, and is not limited by the drawings. Figure 1

[0048] Two slope plates 30, in this embodiment, are soft plate bodies made of EVA material, and the material is not limited, but mainly is a soft and reusable material. The top end of each slope plate 30 is provided with a slope 31 along the width direction. The width of the two slope plates 30 is equivalent to the width of the base plate 20. The other end of the two slope plates 30 is provided with a connecting part 32, and the two connecting parts 32 are composed of a plurality of wedge-shaped blocks, and the size of the wedge-shaped blocks is equivalent to the size of the wedge-shaped blocks of the connecting parts 221 of the two flat areas 21. In this way, the two slope plates 30 can be respectively embedded with the wedge-shaped blocks of the connecting parts 211 of the connecting parts 211 at the front and back ends of the base plate 20.

[0049] The assembled modular teaching aid 10 can be used when children ride a scooter C, a skateboard, or other sports equipment such as a straight row wheel to perform physical fitness training. Please refer to Figure 3 ​As shown, when the child riding the scooter C wants to move the modular teaching aid 10 from the general road surface, the wheels of the scooter C first contact the slope 31 of the slope plate 30, so that the child can easily get on the modular teaching aid 10, and because the scooter C and the slope 31 are in inclined contact, the impact of the scooter C can be avoided to cause the modular teaching aid 10 to move, and after the front wheel of the scooter C moves to the slope plate 30, the weight can be pressed on the modular teaching aid 10, so that the teaching aid 10 does not move, thereby increasing the stability, so that the scooter can smoothly pass through the teaching aid, and prevent the scooter C from slipping during riding due to the movement of the teaching aid.

[0050] When riding, the wheels of the scooter C pass through the wave block 223 when passing through the functional part 222, and can be used on several consecutive long strip-shaped semicircular protrusions 2231. The user needs to hold the handle to avoid deviating from the track, which can train the hand muscles and concentration to improve the control ability.

[0051] The base plate 20 and the slope plate 30 of the modular teaching aid 10 are made of EVA material, which is light and soft, easy to carry and move, and not easy to be injured when colliding. The damage of EVA material will not cause harm to the human body. In addition, through the separable assembly design between the functional area 22 and the two plane areas 21, the functional area 22 can be replaced to change the site, and the terrain variability of the functional part 222 of the functional area 22 can enrich and strengthen the content of the course. The assembly parts 211 and 221 of the plane area 21 and the functional area 22 are complementary wedge blocks, which are easy to combine and separate. In use, the plane area 21 and the functional area 22 are combined with each other, or the position is changed, so that the position change between the functional area 22 and the plane area 21 changes the site and quickly assembles and replaces.

[0052] Figure 4 and Figure 5 The second preferred embodiment of the teaching aid of the present application has the same main structure as the previous preferred embodiment, and the same parts are denoted by the same symbols and will not be described again. Wherein;

[0053] The auxiliary unit 40 is arranged on the functional part 222 of the functional area 22. In this embodiment, the functional part 222 is a groove 224. The auxiliary unit 40 has a swing block 41 and a long plate body 42. The swing block 41 is arranged at the bottom surface of the long plate body 42 near the center. The swing block 41 is arranged in the groove 224, so that the swing block 41 can rotate freely around the groove 224 as a fulcrum to drive the two ends of the long plate body 42 to swing up and down or to rock up and down. The long plate body 42 is higher than the top surface of the base plate 20. The long plate body 42 swings up and down around the swing block 41 as a fulcrum, so that the auxiliary unit 40 forms a structure like a seesaw. The user can move from the front end to the rear end of the long plate body 42 of the auxiliary unit 40. Because of the change of the center of gravity, the long plate body 42 of the auxiliary unit 40 swings up and down or rocks up and down around the swing block 41 as a fulcrum, so that a height difference is generated.

[0054] When the scooter C moves from the front end to the rear end of the long plate body 42, the center of gravity of the scooter gradually shifts. The rear end of the long plate body 42 swings down, so that the user can continue to move forward to the rear end of the teaching aid. Through the arrangement of the auxiliary unit 40, the user can learn to control the change of the center of gravity and overcome the fear caused by the change of the position up and down. When passing through the auxiliary unit 40, the child needs to improve the concentration, carefully judge the change of the position, and stimulate the prefrontal lobe by the change of the position up and down, so as to improve the neural network connection of the brain.

[0055] Figure 6 A third preferred embodiment of the teaching aid provided by the present application has the same main structure as the first preferred embodiment. The same parts are denoted by the same reference numerals and will not be described again. In this embodiment,

[0056] The flat areas 23 of the base plate 20 and the functional area 24 are integrally formed. The two flat areas 23 are arranged at the front and rear ends of the functional area 24. A set of connecting parts 231 of the two flat areas 23 are arranged at the front and rear ends and are connected to the connecting parts 32 of the slope plate 30. The functional part 241 of the functional area 24 is arranged between the two flat areas 23. When the functional area 24 is replaced, the entire base plate 20 needs to be replaced. In addition, the two flat areas 23 and the functional area 24 are integrally formed, so that the combination strength is stable and the assembly process is relatively simple.

[0057] Please refer to Figures 7 to 12 A fourth preferred embodiment of the teaching aid provided by the present application has the same main structure as the first embodiment. The same parts are denoted by the same reference numerals and will not be described again. In this embodiment,

[0058] The plane area 23 of the base plate 20 is provided with a clamping member, in this embodiment, the clamping member includes two clamping portions 25, which are protrusions 251 protruding from the base plate 20;

[0059] A functional area 50 is made of soft and reusable material, such as EVA, but not limited thereto. In this embodiment, the functional area 50 is a slope obstacle block with height and front and back slopes, including a front slope block 51 and a back slope block 52. The bottom surface of the front slope block 51 is provided with an embedding portion 511, which is a groove relative to a clamping portion 25. The bottom surface of the back slope block 52 is provided with an embedding portion 521, which is also a groove, so that the front slope block 51 and the back slope block 52 can be assembled on the base plate 20. The front side of the top surface of the front slope block 51 is provided with a front slope portion 512. The back side of the top surface of the back slope block 52 is provided with a back slope portion 522. The back end surface of the front slope block 51 and the front end surface of the back slope block 52 are respectively provided with a recess 513 and a protrusion 523, which can be embedded in the recess 513, so that the front slope block 51 and the back slope block 52 are connected. The front and back slope blocks 51 and 52 are embedded in the clamping portions 25 of the base plate 20 by the embedding portions 511 and 521 at their bottom. The front and back slope blocks 51 and 52 form a protruding slope on the base plate 20, so that the top surface of the functional area 50 forms a functional portion (slope). In practice, the functional area 50 can also be formed by integrally molding the slope obstacle block. The front and back of the functional area 50 are respectively provided with the front slope portion 512 and the back slope portion 522, and the bottom is provided with the embedding portions 521 / 522, so that the functional area 50 can be directly assembled with the clamping portions 25 of the base plate 20.

[0060] Please refer to Figure 10When the child riding the scooter C advances from a general flat road to the modular teaching aid 10, the wheels of the scooter C first contact the slope 31 of the slope plate 30, so that the child can easily get on the modular teaching aid 10, and because the contact between the scooter C and the slope 31 is inclined, the impact of the scooter C can be avoided to cause the displacement of the modular teaching aid 10, and when the weight of the front wheel of the scooter C moves to the slope plate 30, the modular teaching aid 10 can be pressed to avoid the movement of the modular teaching aid 10, and prevent the scooter C from falling during riding. The base plate 20, the slope plate 30 and the functional area 50 of the modular teaching aid 10 are all made of EVA material, which is light and soft, easy to carry and move, and not easy to be injured when colliding, and the damage of the EVA material will not cause harm to the human body; in addition, through the design of the separation of the functional area 50 and the base plate 20, the assembly and the change of the terrain of the riding site can be easily carried out, and the change of the terrain can enrich the content of the course. Because the connecting parts 23 at both ends of the base plate 20 are complementary in shape, the base plates 20 can also be combined in front of and behind each other in use, and different functional areas 50 are matched to produce the change of the terrain of the site and the rapid assembly and replacement. When the scooter C moves to the functional area 50, the front inclined block 51 can form an upward climbing slope, and the rear inclined block 52 can form a downward sliding slope, so as to stimulate the sense of the user and increase the stimulation intensity and variability of the training. The front inclined part 512 can train the climbing ability of the user, strengthen the muscle use, and train the concentration when riding uphill and downhill, so as to avoid the skew or tilt of the route. In addition, when the rear inclined part 522 is used to slide downhill, the frontal lobe of the user can be stimulated, and the development of the neural network of the brain can be increased.

[0061] In addition, as shown in Figure 11 and Figure 12 The modular teaching aid 10 is provided with two base plates 20, which can be combined with each other through the adjacent connecting parts 231, so that the extension length of the teaching aid can be increased, and each base plate 20 is provided with a functional area 50, so that the teaching aid has two functional parts, that is, two slopes, the complexity of the teaching aid is increased, the control ability of the user can be trained through the change of the short-range continuous slope, the muscle explosive force of the user when climbing the second slope can be trained, and the balance of the user can be trained through the continuous uphill and downhill, so that the user can adapt to the multiple slope changes in an instant.

[0062] Figure 13 and Figure 14 The fifth preferred embodiment of the teaching aid provided by the present application has the same main structure as the previous embodiment, the same structures are denoted by the same symbols, and will not be described again. Wherein;

[0063] The functional area 50 further comprises a connecting block 53, which is an elongated cuboid disposed between the front inclined block 51 and the rear inclined block 52. The connecting block 53 has a connecting protrusion 531 and a connecting recess 532 disposed at two ends thereof, respectively. The connecting protrusion 531 is engaged with the recess 513 of the front inclined block 51, and the connecting recess 532 is engaged with the protrusion 523 of the rear inclined block 52. The bottom surface of the connecting block 53 is provided with two embedding portions 533, which can be embedded with the clamping portions 25 of the base plates 20. The top surface of the connecting block 53 is a flat surface 534. When the front inclined block 51, the connecting block 53 and the rear inclined block 52 are engaged together, the functional portion of the functional area forms a platform protruding from the base plate, so that the user can rise from the front inclined block 51, slide on the connecting block 53 for a distance, and then descend from the rear inclined block 52. Because the length of the functional area 50 is relatively long, two base plates 20 are used to combine a single functional area 50, so that the functional portion of the functional area 50 can span over the two base plates 20, thereby meeting the use length.

[0064] The user can balance through the flat surface 534, train concentration, avoid falling off the flat surface 534, and the flat surface 534 can allow the user to perform an accelerating action, so that the speed of falling off the rear inclined portion 522 can be increased, and the stimulation of the frontal lobe can be increased.

[0065] Please refer to Figure 15 and Figure 16 for the sixth preferred embodiment of the teaching aid provided by the present application, which has the same main structure as the first preferred embodiment. The same parts are denoted by the same reference numerals, and will not be described again. Wherein:

[0066] In order to increase the variability of the teaching aid, the base plates 20 of the above embodiments can be combined to become the base plates 20 of the present embodiment having three different functional areas. The functional portion of the functional area 50 of the frontmost base plate 20 is a slope formed by the front inclined block 51 and the rear inclined block 52, and the functional portions 222 of the functional areas 22 of the middle and rear base plates 20 are wave blocks 223 and grooves 224, respectively. The grooves 224 are provided with the auxiliary units 40. Through the different functional changes on the consecutive base plates 20, the variability of the overall terrain and the play can be increased, and the interest of the user can be improved.

[0067] Through the riding movement of the scooter C and various exercise apparatuses, the core muscle group of the child can be trained, the overall muscle development can be strengthened, and the bad posture can be corrected. Through the terrain changes generated by the functional portions of the functional areas, the stimulation of the vestibular sense can be given, the frontal lobe development of the child can be improved, the reticular formation of the brain can be activated, and the integration of the brain can be promoted. In addition, through the concentration to overcome different terrains, the concentration can be increased, the courage to overcome difficulties can be increased, and the self-confidence can be increased.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
