Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a hand exercise device with lights. Background Art

[0002] With the progress of society, people's living standards are getting higher and higher. So people are gradually paying attention to health issues and starting to exercise. Due to the busy work schedule, more people choose to exercise at home. Therefore, various exercise equipment have begun to enter thousands of households. Among these exercise equipment, there are those that exercise the whole body, and those that exercise the arms, waist, back, legs, etc. Among them, those used to exercise the strength of the hands include: Flying Rod, Arm Strengthener, Gyro Wrist Ball, etc. However, whether it is Flying Rod, Arm Strengthener, Gyro Wrist Ball, etc., they all have the following problems:

[0003] They are all quite long. For example, the Flymax stick is around 150-160cm long, and even smaller arm trainers are generally around 60cm long. Even the smaller wrist gyro balls, due to their handles, are still around 50cm long. Consequently, these exercise devices are quite bulky, making them difficult to store and pack. Especially during transportation, their slender shape can easily be squeezed or bumped by external objects, causing damage. The Flymax stick, at around 150-160cm in length, also takes up a lot of space when in use, making it easy to hit nearby people or objects. Therefore, there are certain requirements for their proper use. Arm trainers and wrist gyro balls are particularly difficult for beginners with no prior training experience and can be challenging to use. The wrist gyro ball, in particular, is nearly impossible for beginners to start and get going. Even with a starting aid, the ball won't continue to spin after the starting aid expires, thus negating the effectiveness of the exercise. These devices are very boring and tedious to use, and there is no interaction between the user and the device. Therefore, it is difficult for novices to arouse their interest in exercise, which easily leads to the inability to persist in exercise, and many people give up halfway. Utility Model Content

[0004] The present invention aims at solving the above problems, overcoming at least one of the shortcomings, and provides a hand exercise device with light.

[0005] The technical solutions adopted by this utility model are as follows:

[0006] A hand exercise device with light includes a fixed part and a rotating part. The fixed part is used to form a path, and the rotating part rotates along the path. The rotating part is provided with a light-emitting device, which is electrically connected to a switch assembly. The rotation of the rotating part drives the switch assembly to automatically close, forming a circuit path, and the light-emitting device emits light.

[0007] In actual use, the hand exercise device, due to the provision of a light-emitting device, produces a lighting effect during exercise, enhancing the exercise environment. Compared to existing exercise equipment, this makes the entire exercise process less tedious and boring. The lighting effect further enhances the overall exercise environment, especially at night or in dimly lit environments.

[0008] Furthermore, the lighting device automatically illuminates as the rotating portion rotates; when the rotation stops, the lighting also stops. This makes it not only extremely convenient and easy to use, but also allows the lighting effect to start and stop with the start and stop of exercise. This allows the lighting to interact with the user, increasing the enjoyment of the exercise process and promoting their motivation.

[0009] In one embodiment of the present invention, the switch assembly includes a circuit control board, on which an elastic connector and a battery are provided; the elastic connector and the battery are both electrically connected to the light emitting device;

[0010] One end of the elastic connector is fixedly connected to the circuit control board, and the other end is a movable end; when the rotating part rotates, the movable end of the elastic connector is displaced and comes into contact with the battery.

[0011] In actual use, the elastic connector, the battery, and the light-emitting device are electrically connected to form a circuit path. The circuit control board has a built-in control program for controlling the light-emitting duration or light-emitting effect of the light-emitting device.

[0012] Furthermore, the elastic connector is a conductor. When the rotating portion rotates, the elastic connector generates inertia. Since one end of the connector is movable, the movable end will displace and cause the elastic connector to elastically deform. This elastic deformation generates a rebound force, causing the movable end of the elastic connector to shake uncontrollably. When the connector automatically contacts the battery during shaking, the circuit is connected to form a pathway, allowing the light-emitting device to emit light. The duration of each contact is determined by the control program built into the circuit control board according to actual needs. When there are multiple light-emitting devices, the circuit control board can also control the order in which they light up to create a predetermined lighting effect.

[0013] When the rotating part stops rotating, the elastic connector will gradually return to its original static state under the action of the rebound force, thereby automatically stopping contact with the battery, that is, the circuit will be automatically disconnected, and the light-emitting device will automatically stop emitting light.

[0014] In one embodiment of the present invention, the number of batteries is greater than or equal to two; the batteries are arranged on the circuit control board around the elastic connecting member.

[0015] Arranging multiple batteries can form multiple circuit paths. In addition, multiple batteries increase the probability of contact with the movable end of the elastic connector, thereby increasing the probability of the light-emitting device emitting light, thereby improving the light-emitting effect.

[0016] In one embodiment of the present invention, a circuit antenna is provided on a side of the movable end of the elastic connector facing the battery; when the movable end of the elastic connector is displaced, the circuit antenna contacts the battery.

[0017] In actual use, the circuit antenna is a conductor and has no fixed shape. It is mainly used to increase the contact area between the elastic connector and the battery, thereby improving the contact efficiency between the elastic connector and the battery.

[0018] In one embodiment of the present invention, two batteries are provided on the circuit control board and are respectively arranged on both sides of the elastic connector; the movable end of the elastic connector is provided with circuit antennas on both sides; the two circuit antennas correspond one-to-one to the two batteries.

[0019] The two batteries are used to form two circuits. The two circuit antennas are both conductive and have no fixed shape. The two circuit antennas are mainly used to increase the contact surface between the two sides of the elastic connector and the two batteries, thereby improving the contact efficiency between them.

[0020] In one embodiment of the present invention, a counterweight portion is provided on the rotating portion, and a switch assembly is disposed in the counterweight portion.

[0021] In actual use, the counterweight is primarily used to generate centrifugal force when the rotating part rotates, thereby simplifying the initial and sustained rotation of the rotating part. Placing the switch assembly within the counterweight concentrates the weight of the switch assembly at the counterweight, allowing the centrifugal force generated by the switch assembly to be superimposed on the centrifugal force generated by the counterweight when the rotating part rotates. If the switch assembly is located within the rotating part, away from the counterweight, the centrifugal force generated by the switch assembly will offset the centrifugal force generated by the counterweight when the rotating part rotates.

[0022] In one embodiment of the present invention, the light emitting device is housed in a counterweight portion, and the counterweight portion is made of a light-transmitting material.

[0023] The light-transmitting material can allow the light generated by the light-emitting device to be better illuminated from the counterweight portion. The light-transmitting material can be a fully transparent material, or a material that only transmits light but is not completely transparent.

[0024] In one embodiment of the present invention, the light emitting device is housed outside the counterweight portion and located on the rotating portion, and the rotating portion is made of a light-transmitting material.

[0025] The light-transmitting material can allow the light generated by the light-emitting device to be better irradiated from the rotating part. The light-transmitting material can be a fully transparent material, or a material that only transmits light but is not completely transparent.

[0026] In one embodiment of the present invention, the number of the light emitting devices is greater than or equal to two, and they are respectively disposed in the counterweight portion and the rotating portion, and both the rotating portion and the counterweight portion are made of light-transmitting materials.

[0027] The light-transmitting material can allow the light generated by the light-emitting device to be better illuminated from the rotating part, the counterweight part and the interior. The light-transmitting material can be a fully transparent material, or a material that only transmits light but is not completely transparent.

[0028] In one embodiment of the present invention, the elastic connecting member is a spring; the circuit antenna is a conductive material; and the light-emitting device is a light bulb or a light strip.

[0029] The beneficial effects of the present invention are as follows: the provision of a light-emitting device on the hand exercise device makes the entire exercise process more enjoyable and visually appealing, rather than tedious, thereby increasing the user's interest in exercise. Furthermore, a switch assembly is provided so that the light-emitting device can follow the user, automatically illuminating and stopping during exercise. Therefore, the device is not only simple and convenient to use, but also allows the light-emitting device to interact with the user during exercise, further enhancing the enjoyment of exercise and promoting the user's enthusiasm for exercise.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0041] In the description of this application, it should be noted that the terms "inner" and "outer" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended solely to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0042] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0043] The present invention will be described in detail below with reference to the accompanying drawings.

[0044] Example 1

[0045] like Figures 1 to 3As shown, a hand exercise device with light comprises a fixed portion 1 and a rotating portion 2. The fixed portion 1 forms a path, and the rotating portion 2 is annular and rotates along the path. The diameter of the annular rotating portion 2 is approximately 25-30 cm. Therefore, the overall space occupied is significantly reduced compared to existing exercise equipment. This not only significantly reduces the requirements for the use scenario of the hand exercise device with light, but also makes it easier and more convenient to pack, store, and transport.

[0046] Moreover, compared with the slender exercise equipment in the prior art, the circular ring structure is more resistant to pressure and collision, making the whole body less likely to be damaged.

[0047] The fixing portion 1 includes a first fixing member 11 and a second fixing member 12. Both the first fixing member 11 and the second fixing member 12 have interconnected channels 5 at both ends. Both channels 5 are arc-shaped channels 5, with the radius of the circle in which the two arc-shaped channels 5 are located being equal, and the two arc-shaped channels 5 together form a circular path.

[0048] The two fixing members jointly form a path, so that the rotating part 2 can be more stable when rotating, and the problem of having support on one side while not having support on the other side, thereby affecting the rotation stability, will not occur.

[0049] In actual use, the two arc-shaped channels 5 allow each part of the rotating part 2 to smoothly pass through the channels 5 when the rotating part 2 rotates, without being stuck in the channels 5.

[0050] In addition, a handle portion 3 is provided on the fixing portion 1 .

[0051] The first fixing member 11 and the second fixing member 12 are connected via the handheld portion 3. One end of the handheld portion 3 is connected to the first fixing member 11, and the other end is connected to the second fixing member 12.

[0052] The two fixing members are connected by the handheld portion 3 so as to form a whole with the handheld portion 3. Thus, the track formed by the two fixing members can be more stable, and the rotation of the rotating portion 2 can be ensured to be smoother.

[0053] The two fixing members do not necessarily need to be located at both ends of the handle portion 3. Both fixing members may be located at neither end of the handle portion 3. For example, the handle portion 3 may be extended so that both ends of the handle portion 3 bypass the periphery of the two fixing members and extend from the other side of the fixing members, thereby positioning the fixing members at non-end portions of the handle portion 3. Alternatively, one fixing member may be located at one end of the handle portion 3, while the other end of the handle portion 3 bypasses the periphery of the fixing member and extends from the other side of the fixing member, thereby positioning the other fixing member at a non-end portion of the handle portion 3.

[0054] During production, the first fixing member 11 , the second fixing member 12 and the hand-held portion 3 are generally formed as one piece, and the whole is divided into two parts, an upper part and an lower part.

[0055] During assembly, the first and second fixing members 11, 12 are each looped around the exterior of the rotating portion 2; that is, the first and second fixing members 11, 12 are each composed of an upper and lower portion, which are looped around the exterior of the rotating portion 2 and then assembled and fastened together using screws, snaps, or similar fastening structures. At this point, the handle 3 is positioned in the center of the rotating portion 2, or alternatively, in the axial direction of the rotating portion 2. The first and second fixing members 11, 12 may be arranged in an array along the annular rotating portion 2, or not.

[0056] Each channel 5 has a housing cavity within its inner wall, housing a power assist device that abuts the outer wall of the rotating portion 2. The power assist device includes a fixed shaft, both ends of which are fixed within the housing cavity. A roller 6 is sleeved around the outer surface of the fixed shaft, abutting the outer wall of the rotating portion 2.

[0057] or,

[0058] The power assist device is a ball 7 , which is accommodated in the accommodating cavity and abuts against the outer wall surface of the rotating part 2 .

[0059] Whether the roller 6 or the ball 7 is provided, the contact area between the outer wall of the rotating part 2 and the inner wall of the channel 5 can be reduced, thereby reducing the corresponding friction resistance, and thus allowing the rotating part 2 to smoothly and fluently pass through the channel 5 when rotating.

[0060] A counterweight portion 4 is provided inside the rotating portion 2. The counterweight portion 4 is used to generate centrifugal force when the rotating portion 2 rotates, making the hand exercise device simpler and more convenient to start, thereby meeting the needs of more users, such as novices, women with insufficient hand strength, children, etc.

[0061] Through other types of integral structures, the counterweight portion 4 can also be connected to the outside of the rotating portion 2 (not shown in the figure). Regardless of whether the counterweight portion 4 is arranged inside or outside the rotating portion 2, the two will move synchronously and there will be no relative movement.

[0062] When the rotating part 2 is stationary, only a portion of the rotating part 2 is accommodated in the channel 5 ; the remaining portion is exposed outside the fixed part 1 .

[0063] Reference Figure 4 and Figure 5The rotating portion 2 is provided with a light-emitting device 20, which is a light bulb or light strip, and is electrically connected to a switch assembly 30. The switch assembly 30 is disposed within the counterweight portion 4. Placing the switch assembly 30 within the counterweight portion 4 concentrates the weight of the switch assembly 30 at the counterweight portion 4, thereby allowing the centrifugal force generated by the switch assembly 30 to be superimposed on the centrifugal force generated by the counterweight portion 4 when the rotating portion 2 rotates. If the switch assembly 30 is disposed within the rotating portion 2, away from the counterweight portion 4, the centrifugal force generated by the switch assembly 30 will offset the centrifugal force generated by the counterweight portion 4 when the rotating portion 2 rotates.

[0064] The switch assembly 30 includes a circuit control board 31 , on which are disposed an elastic connector 33 and a battery 32 . The elastic connector 33 is a spring, and both the elastic connector 33 and the battery 32 are electrically connected to the light emitting device 20 .

[0065] One end of the elastic connector 33 is fixedly connected to the circuit control board 31, and the other end is a movable end. When the rotating part 2 rotates, the movable end of the elastic connector 33 moves and contacts the battery 32. In other words, the rotation of the rotating part 2 automatically closes the switch assembly 30, forming a circuit path, thereby causing the light-emitting device 20 to emit light.

[0066] A circuit antenna 34 is provided on the side of the movable end of the elastic connector 33 that faces the battery 32. When the movable end of the elastic connector 33 is displaced, the circuit antenna 34 contacts the battery 32. The circuit antenna 34 is a conductor and has no fixed shape; any conductive material can be used. Its primary function is to increase the contact area between the elastic connector 33 and the battery 32, thereby improving the contact efficiency between the two.

[0067] In actual use, the elastic connector 33, the battery 32, and the light emitting device 20 are electrically connected to form a circuit path. The circuit control board 31 has a built-in control program for controlling the light emitting time or light emitting effect of the light emitting device 20.

[0068] In addition, the elastic connector 33 is a spring, which is a conductor. When the rotating part 2 rotates, the elastic connector 33 will generate inertia. Since one end of the elastic connector 33 is a movable end, the movable end will be displaced and the elastic connector 33 will be elastically deformed. The elastic deformation will generate a rebound force, so the movable end of the elastic connector 33 will shake uncontrollably. When it automatically contacts the battery 32 during the shaking process, the circuit will be connected to form a path, so that the light-emitting device 20 will emit light. Each time it contacts, the lighting time of the light-emitting device 20 is determined by the control program built into the circuit control board 31 according to actual needs. When the number of light-emitting devices 20 is multiple, the circuit control board 31 can also control the lighting order between each other to form a predetermined lighting effect, etc.

[0069] When the rotating part 2 stops rotating, the elastic connector 33 will gradually return to its original static state under the action of the rebound force, thereby automatically stopping contact with the battery 32, that is, the circuit will be automatically disconnected, and the light-emitting device 20 will automatically stop emitting light.

[0070] When the light emitting device 20 is accommodated in the counterweight portion 4 , the counterweight portion 4 is made of a light-transmitting material, that is, the position on the rotating portion 2 corresponding to the counterweight portion 4 is also made of a light-transmitting material.

[0071] When the light emitting device 20 is accommodated outside the counterweight portion 4 and located on the rotating portion 2 , the rotating portion 2 is made of a light-transmitting material.

[0072] When the number of the light emitting devices 20 is greater than or equal to two, and they are respectively arranged in the counterweight portion 4 and the rotating portion 2, the rotating portion 2 and the counterweight portion 4 are both made of light-transmitting materials.

[0073] The light-transmitting material can allow the light generated by the light-emitting device 20 to be better irradiated from the counterweight portion 4 and / or the rotating portion 2. The light-transmitting material is a fully transparent material, or a material that is only light-transmitting and not completely transparent, such as a frosted material.

[0074] In actual use, the user first grasps the handle 3 and then performs a small, circular shaking motion. Because the counterweight 4 within the rotating portion 2 is present, this swinging motion generates centrifugal force, driving the rotating portion 2 to rotate synchronously along the path. At this point, various sections of the rotating portion 2 sequentially pass through the channel 5. As the duration of this shaking motion increases, the user's hands become stronger.

[0075] Compared with existing exercise equipment, the presence of the counterweight portion 4 makes the hand exercise device with light very easy to use and can easily drive the rotating portion 2 to rotate. Even users with no exercise experience, or users with weak arm strength such as women and children, can easily rotate the rotating portion 2 and maintain the rotating portion 2 in continuous rotation, thereby achieving the effect of exercising the hands.

[0076] Due to the provision of the light-emitting device 20, the hand exercise device generates a lighting effect during exercise, enhancing the exercise environment. Compared to existing exercise equipment, the entire exercise process is no longer dull or tedious. The lighting effect further enhances the overall exercise environment, especially at night or in dimly lit environments.

[0077] Furthermore, the lighting device 20 automatically illuminates as the rotating portion 2 rotates; when it stops rotating, the lighting also stops. This makes it not only extremely convenient and easy to use, but also allows the lighting effect to start and stop with the start and stop of exercise. This allows the lighting to interact with the user, enhancing the enjoyment of the exercise process and promoting the user's motivation to exercise.

[0078] Example 2

[0079] The difference between this embodiment and embodiment 1 is that:

[0080] The fixing portion may also be a single arc-shaped fixing portion with a longer arc line (not shown in the figure).

[0081] For example, the arc length covers 25%-80% of the entire circular path. The specific value can also exceed this range and needs to be set according to actual needs.

[0082] When the number of the fixing portion is one (not shown in the figure):

[0083] The interior of the fixed part is provided with a channel with two ends communicating with each other, the channel is in an arc shape, and the arc-shaped channel provides a path for the rotating part to rotate. The rotating part is in an annular shape.

[0084] When the rotating part is stationary, part of the rotating part is accommodated in the channel; the remaining part is exposed outside the fixed part.

[0085] When the rotating part rotates, the rotating part rotates on itself and the parts of the rotating part pass through the channel in sequence.

[0086] Example 3

[0087] The difference between this embodiment and embodiment 1 is that:

[0088] When the number of the fixing parts is greater than or equal to three (not shown in the figure), the multiple fixing parts can be distributed in an array along the annular rotating part 2 or not.

[0089] Example 4

[0090] The difference between this embodiment and embodiment 1 is that:

[0091] Reference Figure 6 and Figure 7 ,

[0092] The number of batteries 32 is greater than or equal to two; a plurality of batteries 32 are arranged on the circuit control board 31 around the elastic connecting member 33 .

[0093] The multiple batteries 32 can form multiple circuit paths and increase the probability of contact with the movable end of the elastic connector 33, thereby increasing the probability of the light emitting device 20 emitting light and improving the light emitting effect.

[0094] In actual use, two batteries 32 are provided on the circuit control board 31 and are respectively arranged on both sides of the elastic connecting member 33; the movable end of the elastic connecting member 33 is provided with circuit antennas 34 on both sides; the two circuit antennas 34 correspond one-to-one to the two batteries 32.

[0095] The two batteries 32 are used to form two circuits, respectively. Figure 8 The two circuit antennae 34 are both conductors and have no fixed shape. The two circuit antennae 34 are mainly used to increase the contact area between the two sides of the elastic connector 33 and the two batteries 32, thereby increasing the contact efficiency between them.

[0096] The above description is only a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformation made by using the contents of the description and drawings of the present invention, directly or indirectly applied in other related technical fields, is also included in the scope of protection of the present invention.
