More specifically, the eccentric rotated by the driving means by improving the structure of the driving means for driving the seesaw movement by transmitting the vibration generated through the rotation of the eccentric shaft to the footrest of the exercise equipment in contact with the body of the exerciser It is configured to be parallel to the surface of the movement trajectory according to the rotational direction of the shaft and the movement of the scaffold, and furthermore, the shaft coupled to the housing as well as the shaft coupled to the scaffold are pivotally connected to reduce the tension on the shaft. It is possible to reduce the capacity of the motor according to the operation of the scaffolding, to minimize the noise, impact, and wear, and to achieve a more compact configuration than the existing products. will be.

Recently, a variety of indoor exercise equipment that are simple and weather-independent have been developed because it is not easy for modern people to exercise every day. In general, a user may use such a treadmill or step machine to strengthen the lower body strength. In addition to exercise equipment that exercises by applying force directly, a so-called vibrator that releases the muscles that are gathered by vibration without the user's effort is introduced, and such exercise equipment is driven by the driving motor. It rotates the shaft and vibrates the scaffold up and down.

Conventional technology for such a vibrator is registered Patent No. 283875 "Strength Strengthening Exercise Mechanism" (2000.12.13), the strength strengthening exercise mechanism disclosed in Patent No. 283875 is a base that is placed on a horizontal plane; A post installed in front of the base; A footrest installed on the base so as to be movable up and down and on which the user puts his foot; A driving device disposed in the base to periodically lift both sides of the scaffolding in a seesaw manner; And a control panel mounted on the post to control driving of the driving device, wherein the driving device comprises: a driving source mounted to the base; A pair of drive pulleys fixed to the shaft of the drive source; A pair of driven pulleys disposed on both sides of each of the driving pulleys and connected by a belt; A pair of eccentric shafts fitted to the driven pulleys and disposed so as to have a predetermined obtuse phase difference therebetween; A bracket installed on the base to rotatably support both ends of each eccentric shaft; And a lower end rotatably connected to both ends of each of the eccentric shafts protruding from the bracket, and an upper end rotatably connected to the underside of the foot plate, and connecting rods that operate the foot plate in a seesaw manner by rotation of the eccentric shafts. Consists of the included configuration.

This strength strengthening exercise mechanism is a seesaw that the power generated from the driving source is transferred to the driven pulleys located on both sides by the belt, and both sides of the scaffold alternately as the driven shaft rotates the driven pulleys formed with eccentric shafts, respectively. Since the motion occurs, not only friction loss occurs between the belt and the pulley when driving the drive source, but also a lot of power is required to rotate the pair of driven pulleys, which requires a lot of load of the drive source during normal operation. It will increase the power consumption. In addition, according to the service life of the belt, maintenance is required continuously, and the composition of the sports equipment is very complicated, so it is not easy to replace the belt or damaged parts after long-term operation. There is a problem that is unsuitable for use in a place where a quiet operation is required.

Subsequently, exercise apparatuses for solving the above problems have been introduced, including the registered patent application No. 0568476 『Exercise Vibrator for Exercise Equipment』 (2006.03.31), filed by the present applicant, and registered Patent No. 0394568 Seesaw exercise mechanism (Jul. 31, 2003), Published Patent No. 2005-118149 『Multi-vibration exercise machine』 (2005.12.15), Publication No. 2005-118383 『Seesaw exercise mechanism using vibration』 (2005.12.19) Can be.

Registered Patent No. 0568476, Vibrator for exercise equipment (2006.03.31), tried to make the power transmission mechanism more compact and to reduce noise, but it also has a drive shaft connected to the drive motor, and the drive motor and the drive shaft are belted. It is configured to rotate the drive shaft by connecting to the problem that the problem of belt service life, noise generation problems caused by the belt drive is not yet perfect. Furthermore, Patent Publication No. 0568476 is configured to contact the support block coupled with the scaffold while the rolling bearing is rotated according to the rotation of the eccentric shaft to reduce the operation noise, but each component is not connected to the scaffold conventionally, It was able to reduce operating noise rather than the instrument, but did not get much better effect.

In addition, Korean Patent No. 0394568 "Vibration Seesaw Exercise Device" (2003.07.31) is located on the case and the upper surface of the case, the footrest is formed so as to put the limbs of the user, the driving device for providing a seesaw movement on the footrest And a control panel for controlling the operation of the driving device, and a muscle strength-enhancing exercise mechanism comprising a post for connecting the case and the control panel to each other, comprising: a driving motor for providing power to the driving device; An eccentric driven shaft connected to generate vibrations according to the rotation of the drive shaft, a driven shaft fixing frame for fixing the eccentric driven shaft, a crank arm for transmitting the vibration generated from the eccentric driven shaft to the scaffolding, and the crank arm.

In Patent No. 0394568, the eccentric driven shaft is connected to the drive motor in order to reduce the power loss and the operation noise of the drive motor. However, the motion of the crank arm is moved up and down by the eccentric driven shaft. The surface and the motion trajectory of the scaffold for seesaw movement are formed to be perpendicular to each other, that is, to cross each other, so that all vibrations driven by the driving motor are not effectively transmitted to the scaffold and are lost to the bottom plate. Due to the drive motor also causes a power loss, there is still a problem to be solved. In this case, when the crank arm is transmitted to the eccentric shaft fixing frame as it is caused by the vertical vibration, the vibration noise is also transmitted to the floor surface of the room where the seesaw exercise device is installed through the fixed base. Vibration noise transmitted to the floor is a cause of inter-floor noise, which is particularly problematic in the case of apartments.

JP-2005-118149, 『Multi Vibration Exerciser』 (2005.12.15) also tried to reduce the power loss of the motor by directly combining the drive shaft and the eccentric cam part rotated by the motor driving force on one side of the motor without a separate belt for driving. Is operated by friction between the scaffolding and the driving means by constructing a connecting rod which is hinged to the upper part of the bearing housing which is coupled to the outside of the eccentric cam part via a bearing and is connected to the foot plate to change the irregular vibration movement of the eccentric cam part into vertical movement. In order to reduce the noise, however, the direction of movement of the connecting rod and the up and down movement of the footrest are configured to be mutually different. Therefore, there is a problem that the motor power loss is required. In addition, the tension of the connecting rod connecting the footrest and the housing, including tension, impact, noise, There is a problem that can not effectively solve the wear.

In addition, Patent Publication No. 2005-118383, `` Seesaw exercise device using vibration '' (2005.12.19), is intended to solve the problems of the prior art described above to reduce the operation noise and to solve the problem of overloading the driving motor. It was. However, it is also provided with a separate drive shaft connected to the drive motor and is configured to rotate the drive shaft by connecting the drive motor and the drive shaft by the belt, the problem that the problem of the service life of the belt, noise generation due to the belt drive is not yet perfect have.

The present invention for solving the above problems is to provide a seesaw exercise mechanism that can achieve the maximum movement effect by effectively transmitting the driving force of the drive device to the scaffold while reducing the power of the drive motor.

In addition, the present invention has a link arm configured to be pivotable under the footrest to reduce the tension applied to the shaft connecting the footrest and the housing, and at the same time further comprising a guide member between the footrest and the base panel in contact with the bottom surface more stable footrest In order to achieve the seesaw movement of the present invention, as well as the present invention to enable a compact configuration that can reduce the volume of the drive unit to maximize the vibration effect and ultimately minimize the noise, impact, wear, etc. during the operation of the scaffolding The purpose is to provide a seesaw exercise apparatus that can be.

Therefore, when the exerciser is raised, the present invention causes the scaffold to move up and down on the basis of the central axis 12. The surface formed by the seesaw motion trajectory is parallel to the horizontal direction. And the footrest on which the left foot of the athlete is placed is called the left footboard and the footrest on which the right foot of the athlete is placed is called the right footboard.

In addition, in the present invention, the lifting and lowering is not only a motion of repeatedly lifting and lowering vertically, but also in an oblique direction, that is, the lifting and lowering by the motion of the motor rotation shaft in a state where the crank member 40 such as a shaft is inclined. It is a comprehensive concept that includes a repetitive exercise.

As shown in FIGS. 1 to 4, the seesaw exercise apparatus according to the present invention has a plurality of support protrusions 11 provided in a longitudinal direction at a central portion of the base panel on a long horizontal base panel 10. The number is preferably two. A central shaft 12 is coupled to the support protrusion, and the scaffold 20 is placed on the central shaft. Here, the scaffold 20 should be a seesaw movement in the vertical direction with respect to the central axis 13, so that the central axis is preferably rotatably installed on the support protrusion 11, and in order to reduce friction, the support is coupled with the central axis. The protrusion is preferably provided with a bearing (not shown). Furthermore, it is preferable to provide a separate support member 21 on the bottom of the scaffold for stable coupling of the central axis and the scaffold and the left and right sides of the scaffold for stable oscillation of the seesaw type.

The motor 30 is arranged on the base panel 10. The arrangement of the motors is arranged such that an imaginary surface formed by the rotation of the motor and a horizontal axis of the base panel are parallel as shown in the drawing. That is, the rotation shaft 31 of the motor should be arranged so as to be placed in the longitudinal direction of the base panel, and the crank member 40 is connected to the motor and the scaffold to pull the seesaw motion of the scaffold.

The crank member 40 has an eccentric means 42 directly connected to the rotational shaft 31 of the motor, and one end thereof is connected to the eccentric means, and the other end thereof is rotatably connected to the lower portion of the scaffold 20. Arm 44, the link arm 44 is reciprocated by the eccentric movement by the eccentric means 42 located on the motor rotation shaft to move one side of the scaffold up and down, thereby causing the scaffold as a whole Based on the central axis, the left and right scaffolds alternately move up and down.

However, the crank member 40 is to be moved in the vertical direction or the vertical direction in the vertical direction by the drive of the motor, more precisely because of the eccentric means 42 to move up and down, left and right to move up and down The scaffold towed by the crank member is also a seesaw movement while the left and right sides of the scaffold are turned back, front, left and right as a whole.

One end of the link arm 44 is connected to the eccentric means 42 and the other end is pivotally connected to the lower part of the footrest 20, so that the link arm can be integrally connected to the lower part of the footrest or only vertical movement is possible. When connected, the link arm may be in contact with the footrest during operation and friction may occur between the linkarm and the noise may occur due to the friction. Above all, the link arm is weakly connected to the footrest due to repeated friction. In order to solve this problem, the link arm may be pivotable even under the scaffold. More specifically, as shown in FIG. 1, the fixing frame 22 is installed at the bottom of the footrest 20, and a bearing (not shown) is provided at the link arm portion of the side connected to the footrest and the shaft pin 23 is provided. Combine with each other. By doing so, the link arm 44 connected to the scaffold also pushes the scaffold up and down while turning, thus enabling a more stable and smooth scissor movement and reducing the operating noise.

It comprises a bearing 42b, a housing 42c forcibly fitted to the outer circumferential surface of the bearing, and a shaft 42d coupled to the housing to move up and down. Here, the ascending and descending has been described above as a concept including both vertical and oblique elevations, and the method of implementing the crank member is not only a state shown in FIG. 1 but also a state shown in FIG. 7 to be described later. It will be possible.

Looking more specifically, the crank member such as the eccentric means 42 may be coupled to both sides of the motor 30, but in consideration of economical aspects, it is preferable to have the crank member 40 only on one side of the motor. To this end, as shown in FIG. 4, the motor is positioned on an outer side of the base panel 10 so that the crank member 40 connected thereto more accurately links the center of the longitudinal axis of the longitudinal axis of the base panel 10. Make a turn as you go. In this case, the support block 13 is provided separately for the stable support of the motor side 30 coupled to the crank member 40 so that a more stable movement is made. The support block 13 will be coupled to the end of the rotation shaft of the motor, it is preferable that a bearing (not shown) is provided in the portion where the rotation shaft is inserted for smooth rotation of the rotation shaft.

In addition, in the present invention, the eccentric means 42 is directly connected to the motor rotation shaft 31, which has a separate drive shaft connected to the rotation shaft of the motor as confirmed in the problem of the prior art and connects them with a belt and the drive shaft In the method of driving the scaffold by providing a separate crank member such as a separate eccentric means in the friction between the belt and the drive shaft when driving the drive source is a problem that the maintenance must be continued according to the service life of the belt, and another This is because a lot of power is required for the motor to rotate the drive shaft, resulting in an increase in power consumption. In particular, there is a problem that a lot of noise occurs when driving the belt. Accordingly, in the present invention, as shown in the drawing, the rotation shaft 31 is provided on one side of the motor, and the eccentric means 42 is directly coupled to the rotation shaft to solve the problem caused by the belt.

However, in the configuration of the motor and the eccentric means as described above, it is preferable to select the capacity of the motor in consideration of the problem that the load may be applied to the motor. Alternatively, although not shown in the drawing, an eccentric means for connecting a speed reducer to the motor side and allowing up, down, left and right vibrations of the scaffold on one side of the connected speed reducer may solve the load problem of the motor and allow a stable seesaw motion. have.

In addition, as shown in Figs. 1 and 4, the housing 42c is provided with a force fitting in the bearing 42b, and a through hole 42e is provided in the upper portion of the housing 42c so that one end of the shaft 42d is provided. It is screwed and fixed to the coupling hole (42e), the through-hole fastening hole 61 is formed in one side direction of the coupling hole (42e) is fixed by the fastening pin 62. A buffer member is provided between the housing 42c and the shaft 42d to suppress shock, noise, and abrasion. As illustrated in FIG. 1, the buffer member 42f has a ring shape, and the housing and shaft It has a washer function to harden the coupling state.

Furthermore, the bearing of the present invention is preferably a rolling bearing, more preferably a careful bearing that can center itself. In addition, the motor is provided with a balancer (not shown) made to be eccentrically opposite to the eccentric direction of the eccentric means in order to compensate for the eccentric mass of the eccentric means coupled to the motor rotation shaft to perform the eccentric movement.

In addition, in the specification of the present invention, the link arm 44 and the shaft 42d are separately described and described, but as shown in the drawings, it may be implemented in one configuration.

The present invention may further include a guide member 50 between the base panel 10 and the scaffold 20 to help stabilize the seesaw movement of the scaffold as shown in FIG. That is, the support block 14 is positioned on one side or both sides of the base panel, and the guide member 50 is coupled to the guide member 50 to the shaft pin 51, the eccentric motion member 52, and the eccentric motion member. It comprises a combined lifting member 53, a fastening member 54 for connecting the elevating member and the footrest 20, and a rotating member 55 to ensure the amplitude that appears during the swing movement of the elevating member. In this case, as shown, the eccentric motion member 52 of the guide member 50 has the same configuration as the eccentric means 42 composed of the cam, the bearing, and the housing as described above, of the guide member 50 The elevating member 53 has the same configuration as the shaft 42d and the link arm 44 of the eccentric means described above, and thus a detailed description thereof will be omitted. In addition, the fastening member 54 connecting the elevating member 53 to the footrest 20 has a cross-sectional shape, and a perforated long hole 54a is formed at the center thereof, so that the elevating member 53 is inserted. In addition, the lifting member has a screw thread is formed is inserted into the long hole (54a) and the nut (54b) is fastened to prevent the departure from the long hole.

At this time, due to the eccentric movement of the eccentric movement member 52, the elevating member 53 is a swing movement, there is a problem that the tension is applied to the elevating member while the swing movement and the elevating member has a certain amplitude There may be a problem that can not function as a stable guide member to solve this problem it is preferable to have a rotating member 55 to limit and ensure the amplitude of the elevating member. As such a rotating member, as shown in FIG. 6, it is preferable to use a ball joint 57 or a rubber 59 having good elastic force. The ball joint 57 includes a body 57a, a rotation rod 57b seated on the body, and a cover 57c coupled to the body while preventing the rotation rod from being separated from the body, as shown in FIG. 6A. It is done by Although not shown in detail in the embodiment of the present invention, the upper and lower portions of the body is preferably provided with a means for engaging with the elevating member, the means of engagement by means of bushings, welding method, screw method It will be possible to combine by. In addition, the rubber member 59 includes a rubber 59a having a circular column shape as shown in FIG. 6B, and a connection member 59b mounted on upper and lower surfaces of the rubber. Both ends of the connection member are coupled to the elevating member by a coupling means, the method is preferably used a coupling method such as a ball joint.

As mentioned above, the present invention may have a spherical shape in which the link arm 44 is coupled to the scaffold 20 in a vertical position rather than in an inclined state. In this case, even if the link arm 44 is placed vertically, the operation direction of the link arm which pulls the rotational direction of the motor and the up-down direction of the scaffolding does not change from the above-described direction, and thus the operation noise is reduced even by the deformed configuration. The same effect can be achieved as in the previous description, such as reducing power consumption and reducing power consumption. However, when the link arm 44 is erected vertically, since the distance between the base panel and the scaffold is increased, there may be a disadvantage in that a more compact exercise device may not be obtained, such as a large volume. Since there is a problem that a separate stabilizer such as the guide member 50 is required for the stable movement of the scaffold, the link arm is preferably connected to the scaffold in an inclined form rather than vertically connected to the scaffold.

In the above description of the present invention with reference to the accompanying drawings, the description has been made mainly on the seesaw movement device having a specific shape and configuration, the present invention can be variously modified and changed by those skilled in the art, such modifications and changes are the protection of the present invention Should be interpreted as being within the scope.

According to the seesaw movement apparatus according to the present invention, it is possible to reduce the power of the drive motor, while allowing a compact configuration to maximize the vibration effect and minimize the noise, impact, wear, etc. during the operation of the scaffold. In addition, by having a link arm configured to be pivotable under the footrest, the tension between the foothold and the shaft connecting the housing is reduced, and at the same time, a guide member is further provided between the footrest and the base panel in contact with the bottom surface to provide more stable seesaw motion. You can expect this.
