Description

Technical Field

[0001] The utility model relates to the field of finger force testing, in particular to a finger force testing rock block, a rock block assembly and a rock climbing wall. Background Art

[0002] In rock climbing, athletes need to rely on their fingers and hands to complete many movements - they need to use different ways of gripping the rock points to maintain the current body posture and generate enough strength and explosive power to complete the next movement. John Kettle introduced in the book "Rock Climbing Technique: The Practice Guide to Movement Mastery" that there are currently four main climbing techniques: open grip, half-closed grip, full-closed grip and pinch grip, among which the open grip (abbreviated as open grip) is the most common. Different techniques and finger strength during climbing will affect the climber's movement on the rock wall, and then affect the climbing performance and competition results of rock climbers. Therefore, it is very important to objectively and standardizedly evaluate the athlete's finger strength. However, most of the equipment used to measure finger strength on the market cannot measure the force on the fingers during actual climbing. Utility Model Content

[0003] The technical problem to be solved by the utility model is how to measure the force exerted on the fingers during the actual climbing process.

[0004] The utility model provides a technical solution to the above technical problem as follows: a finger force test rock block, comprising a rock block body, an outer wall of the rock block body is provided with a groove, a first pressure sensor is fixed in the groove, and a mounting portion is provided in the middle of the rock block body.

[0005] The beneficial effects of the utility model are as follows: the rock block body is fixed by the mounting part, and the rock climber's fingers are located in the grooves during the climbing process, and the strength of the fingers can be measured by the first pressure sensor.

[0006] The finger force test rock is made into the shape of a climbing rock and can be used for testing during the climbing process. It can accurately capture the actual force conditions of the rock climbers' fingers during the climbing process, improve the accuracy of the measurement, and be more in line with the characteristics of rock climbing.

[0007] The finger strength test rock is simple to operate and can be easily used by athletes to measure finger strength at any time during daily training, so as to better monitor and improve their competitive state.

[0008] The finger strength test rock block is used for testing, which is different from the finger strength test in the training field - the maximum suspended weight test. On the finger strength point of the finger strength board, the weight can be added without falling for 7 seconds until the weight is increased to the limit. The finger strength test rock block is equipped with a first pressure sensor on the rock block body. The finger strength can be measured through the first pressure sensor by simply grasping the rock block body with the fingers. It can accurately evaluate the finger ability and reduce the pressure on the joints and tendons.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the rock block body is provided with a plurality of grooves spaced apart along the circumferential direction.

[0011] The beneficial effect of adopting the above further scheme is: by setting multiple grooves, each finger can be placed in a groove, or four fingers can grasp the same groove at the same time. When the finger grasping position is changed, the mechanical characteristics of each finger grasping point in different directions can be tested.

[0012] Furthermore, four first pressure sensors are arranged at intervals in the groove.

[0013] The beneficial effect of adopting the above further solution is that the four first pressure sensors are respectively used to detect the strength of four fingers except the thumb.

[0014] Furthermore, at least one second pressure sensor is fixed to the end surface of the rock block body, and the second pressure sensor is arranged along the edge of the groove.

[0015] The beneficial effect of adopting the above further scheme is: the second pressure sensor is used to detect the strength of the thumb, and cooperates with the four first pressure sensors to accurately measure the strength of different fingers at corresponding positions and the contribution rate of the five fingers when the subject grasps the point block.

[0016] Further, the mounting portion is a through hole.

[0017] The utility model also provides a rock block assembly, which comprises at least two finger force testing rock blocks, each of which has a different size of a main body of the rock block and is fixedly connected to each other.

[0018] The beneficial effect is that by using rock bodies of different sizes, rock climbers will use different climbing techniques during the climbing process, thereby accurately detecting the finger strength during different climbing techniques.

[0019] Furthermore, the rock block assembly includes two finger force test rock blocks, one of which is a pinching force rock block, and the other is a gripping force rock block. The pinching force rock block is coaxially arranged with the gripping force rock block, and the gripping force rock block is larger in size than the pinching force rock block.

[0020] The beneficial effect of adopting the above further scheme is that the pinching force rock block is used to detect the finger strength of the pinching grip method, and the gripping force rock block is used to detect the finger strength of the gripping grip method.

[0021] Furthermore, the pinching rock block is cylindrical, prismatic or hemispherical, the diameter d of the pinching rock block is 40-50 mm, the width c of the groove of the pinching rock block is 20-40 mm, and the thickness e of the pinching rock block is 20-40 mm.

[0022] Furthermore, the gripping force rock block is cylindrical, prismatic or hemispherical, the diameter D of the gripping force rock block is 90-150 mm, and the groove width a of the gripping force rock block is 30-60 mm.

[0023] The utility model also provides a rock climbing wall, comprising the finger force testing rock block or the rock block assembly.

[0024] The beneficial effect is that the finger strength test rock block or rock block assembly is fixed on the rock climbing wall to measure the finger strength during rock climbing. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] Embodiment 1

[0034] like Figure 1-Figure 5 As shown, this embodiment provides a finger force test rock block, including a rock block body, an outer wall of the rock block body is provided with a groove 1, a first pressure sensor 3 is fixed in the groove 1, and a mounting portion 2 is provided in the middle of the rock block body.

[0035] In this embodiment, the rock block body is installed and fixed by the installation part 2. During the climbing process, the rock climber's fingers are located in the groove 1, and the force of the fingers can be measured by the first pressure sensor 3.

[0036] The finger force test rock is made into the shape of a climbing rock and can be used for testing during the climbing process. It can accurately capture the actual force conditions of the rock climbers' fingers during the climbing process, improve the accuracy of the measurement, and be more in line with the characteristics of rock climbing.

[0037] The finger strength test rock is simple to operate and can be easily used by athletes to measure finger strength at any time during daily training, so as to better monitor and improve their competitive state.

[0038] The finger strength test rock block is used for testing, which is different from the finger strength test in the training field - the maximum hanging weight test (Max Hang Weight). On the finger strength point of the finger strength board, the weight can be added without falling for 7 seconds until the weight is increased to the limit. The finger strength test rock block is provided with a first pressure sensor 3 on the rock block body. The finger strength can be measured by the first pressure sensor 3 by simply grasping the rock block body with the fingers. It can not only accurately evaluate the finger ability, but also reduce the pressure on the joints and tendons.

[0039] Optionally, the rock block body may be in any shape, such as a prism, a cylinder, a sphere, etc., and may also be in an irregular shape.

[0040] Optionally, the groove 1 may be Figure 1-Figure 5 The arc groove shown may also be a rectangular groove.

[0041] On the basis of the above technical solution, the rock block body is provided with a plurality of grooves 1 spaced apart along the circumferential direction.

[0042] By setting a plurality of grooves 1, each finger can be placed in a groove 1, or four fingers can grasp the same groove 1 at the same time. When the finger grasping position is changed, the mechanical characteristics of each finger grasping point in different directions can be tested.

[0043] On the basis of the above technical solution, four first pressure sensors 3 are arranged at intervals in the groove 1 .

[0044] The four first pressure sensors 3 are respectively used to detect the strength of four fingers except the thumb.

[0045] On the basis of the above technical solution, at least one second pressure sensor 4 is fixed to the end surface of the rock block body, and the second pressure sensor 4 is arranged along the edge of the groove 1 .

[0046] The second pressure sensor 4 is used to detect the strength of the thumb, and cooperates with the four first pressure sensors 3 to accurately measure the strength of different fingers at corresponding positions and the contribution rate of the five fingers when the subject grasps the point block.

[0047] On the basis of the above technical solution, the mounting portion 2 is a through hole.

[0048] Specifically, the bolt passes through the through hole and the wall of the climbing wall and is fixed to the wall.

[0049] Alternatively, the mounting portion 2 is a screw or other forms of fixing structures.

[0050] On the basis of the above technical solution, it also includes a data collector and a data processor, all the first pressure sensors 3 and the second pressure sensors 4 are communicatively connected to the data collector, and the data collector is communicatively connected to the data processor.

[0051] The data collector is used to receive pressure signals from multiple pressure sensors. The data processor is an electronic device with storage and computing functions, such as a computer or mobile terminal. The data collector transmits the received pressure signals to the data processor for processing. Furthermore, the data processor can also transmit the processed data to the display for display.

[0052] The main body of the rock block is made of hard materials such as wood, polyurethane or engineering plastics, so as to restore the touch of the rock points as completely as possible while being easy to process.

[0053] Specifically, considering the open grip technique, when the edge of the rock block is wide enough, different climbers will use the first joint surface or the second joint surface of the fingers to grasp the rock point. Therefore, the measuring point (the pressure sensing position of the first pressure sensor 3 and the second pressure sensor 4) is designed to be circular, rectangular, elliptical or other shapes to reduce measurement errors and adapt to the gripping habits of different climbers.

[0054] Embodiment 2

[0055] On the basis of the first embodiment, this embodiment provides a rock block assembly, comprising at least two finger force testing rock blocks, each of the rock block bodies having a different size and fixedly connected to each other.

[0056] By using rock bodies of different sizes, rock climbers will use different climbing techniques during the climbing process, thereby accurately detecting the finger strength during different climbing techniques.

[0057] Specifically, the size of the rock block body refers to the outer diameter or width of the rock block body.

[0058] Based on the above technical solution, the rock block assembly includes two finger force test rock blocks, one of which is a pinching force rock block 100, and the other is a gripping force rock block 200. The pinching force rock block 100 is coaxially arranged with the gripping force rock block 200, and the size of the gripping force rock block 200 is larger than that of the pinching force rock block 100.

[0059] The pinching force rock block 100 is used to detect the finger strength of the pinching grip, and the gripping force rock block 200 is used to detect the finger strength of the gripping grip.

[0060] Based on the above technical solution, Figure 1-Figure 3 As shown, the pinching rock block 100 is cylindrical, prismatic or hemispherical, the diameter d of the pinching rock block 100 is 40-50 mm, the width c of the groove 1 of the pinching rock block 100 is 20-40 mm, and the thickness e of the pinching rock block 100 is 20-40 mm.

[0061] Specifically, the mounting portion 2 of the pinching rock block 100 is a circular hole, the pinching rock block 100 is cylindrical, the groove 1 is an arc-shaped groove, and the pinching rock block 100 is provided with at least five grooves 1 along the circumferential direction.

[0062] Specifically, when the pinching rock block 100 is in a prism shape, its diameter d represents the maximum outer diameter.

[0063] The pinching rock block 100 has the above-mentioned size, is smaller overall and has shallower edges, and the climber can only place each finger in the groove 1. A first pressure sensor 3 is placed in each groove 1, and the climber grasps the point by pinching the fingers inward, so as to measure the finger strength of the climber when pinching the small rock point.

[0064] Different climbers will spread their fingers apart when grasping the point block, and the degree of separation generally depends on the size and habit of the hand. Therefore, the grooves 1 are arranged on the annular surface at intervals according to the arcs of different hand shapes, and the diameter of the pressure sensing position of the first pressure sensor 3 is 15-25 mm.

[0065] The small ring-shaped blocks in the inner circle simulate a wider rock point with right-angled or arc-shaped sides, which requires the climber to use four fingers and the thumb to pinch the point. The force and contribution of the pinching action at the corresponding positions of different fingers are measured. At the same time, the position of the thumb can be adjusted to test the mechanical characteristics of pinching at different relative positions of the thumb and four fingers.

[0066] On the basis of the above technical solution, the gripping force rock block 200 is cylindrical, prismatic or hemispherical, the diameter D of the gripping force rock block 200 is 90-150 mm, and the width a of the groove 1 of the gripping force rock block 200 is 30-60 mm.

[0067] In one example, Figure 1 The gripping force rock block 200 shown is in a prism shape, and the mounting portion 2 is a polyhedral hole of similar shape. The gripping force rock block 200 is in a polyhedral ring shape, and the diameter D of the gripping force rock block 200 is 90-100 mm, and the ring width b is 50-70 mm.

[0068] In another example, Figure 4-Figure 5 As shown, the gripping rock block 200 is hemispherical, the mounting portion 2 is a circular hole, the diameter D of the gripping rock block 200 is 120-150 mm, the thickness is 50-70 mm, and the curvature radius of the groove 1 is 20-40 mm.

[0069] It should be noted that, in addition to the above two specific examples, the diameter D of the gripping force rock block 200 may also be any value between 90-150 mm, and there is no necessary correlation between the diameter D and the shape of the gripping force rock block 200 .

[0070] Specifically, the gripping rock block 200 is provided with a plurality of grooves 1 along the circumference, and four first pressure sensors 3 are arranged in each groove 1 to detect the strength of four fingers except the thumb. Different climbers can separate their fingers when gripping points, and the degree of separation generally depends on the size and habit of the hand. Therefore, the pressure sensing positions of the first pressure sensors 3 are arranged and distributed according to the hand shape arc, and the diameter of the pressure sensing position is 10-30 mm, and the distance between the pressure sensing positions of each first pressure sensor 3 is 5-20 mm. In a specific example, Figure 4 As shown, the gripping rock block 200 is provided with four grooves 1 along the circumferential direction.

[0071] Specifically, Figure 5 As shown, at least one second pressure sensor 4 is provided at the edge of the groove 1 along the width direction of the groove 1, for example, a second pressure sensor 4 is provided at each position near both ends of the groove 1, or three second pressure sensors 4 are provided at intervals along the width direction of the groove 1. The second pressure sensor 4 is used to detect the thumb strength. The edge of the gripping rock block 200 is deep and large, and the climber can grip the point by gripping, and multiple second pressure sensors 4 are arranged to meet the needs of both hands.

[0072] There are three basic ways to grip a rock point: pulling downward, pulling to the sides and pulling upward. The gripping rock block 200 is provided with a plurality of grooves 1. When gripping different grooves 1, it is possible to measure the gripping force of the fingers under the open hand grip method. It can also satisfy the climber's need to use different gripping methods on the same rock point, and measure the strength and contribution rate of each finger in different directions and angles.

[0073] The rock block assembly of this embodiment is different from other equipment that only measures the mechanical characteristics of finger strength and pinch points, and realizes the accurate measurement and rapid evaluation of different finger strengths under different techniques of rock climbers. This technological innovation provides rock climbers with a more accurate training monitoring and evaluation tool, which helps to further study the impact of finger strength on climbing performance in rock climbing.

[0074] The structural design of this embodiment fully considers the actual needs and operating habits of athletes, and designs the finger grip module to be similar to the shape of a rock point, which fully simulates the real climbing scene and is also aesthetically pleasing, thereby enhancing the testing experience of athletes.

[0075] Application prospects of rock block components:

[0076] (1) Training field: Rock block components can be widely used in the daily training of rock climbers, helping athletes to scientifically formulate training plans and improve training effects. At the same time, rock block components can also be used in other sports that require finger strength, such as weightlifting, rowing, etc.

[0077] (2) Selection: In the traditional athlete selection process, the grip strength of young people is mainly tested, which makes it difficult to ensure the accuracy of measurement and the specificity of climbing. Coaches can use rock block components to objectively evaluate the finger strength of athletes. By comparing the measurement data of different athletes, outstanding athletes with special potential can be screened out, providing strong support for the selection of reserve talents in rock climbing and other projects.
