SUMMARY OF THE INVENTION

To promote Chinese kungfu, popularize wrestling and bumping exercise, and improve the national physique, the invention provides a novel wrestling and bumping body builder product. The invention is creative in that the effect of the wrestling technique in wrestling sports, and the Chinese kungfu such as heavy bumping, flapping and beating in martial arts is integrated and achieved via it. A new wrestling and bumping body builder product comprises power system, the power system comprising power machine generating external force, drive component implementing the external force transmission and buffer device acting on the drive component; lifting frame, the lifting frame comprising rectangular frame and fabric pocket thereof, the inner circumference of the rectangular frame being larger than the periphery of the wrestling and bumping surface plate enables the lifting frame to separate from the lifting frame and the wrestling and bumping surface plate mutually at a preset distance so as to prevent the lifting frame from bumping against the wrestling and bumping surface plate when falling down, the fabric pocket being assembled on the rectangular frame allows to be released, tightened and replaced; wrestling and bumping surface plate, the wrestling and bumping surface plate comprising shock absorption device and spacers, and being shaped in rectangle, preset with a thickness and cast from reinforced concrete by pouring, prior to full solidification the placement surface of the support for supporting the wrestling and bumping surface plate being employed to die cast the wrestling and bumping surface plate to form a groove fitted in with the placement surface of the support so as to position the wrestling and bumping surface plate, the periphery of the wrestling and bumping surface plate being preset with rings or screw holes for fixing spacers to be arranged on the wrestling and bumping surface plate; support, the support being a frame is shaped in a rectangular box, the support being a frame for supporting and fixing the power system and the wrestling and bumping surface plate, being linked with a support rod by a chain, and installing and balancing the lifting frame by the support rod; and support rod, the support rod being a part for supporting and balancing the lifting frame and being in abutment with the connecting rod of the drive component of the power system, and the support rod being preset with portions and holes for assembling the chain and being linked with the support with the chain, and the support rod playing a role for the lifting frame in power transmission and frame body balancing, allowing mounting, dismantling and replacing; the technical scheme of this product is that in a driving mode the lifting frame that carriers a human body is lifted to a certain height under the action of the external force and subjected to a falling motion until falling to a designated horizontal plane, and therefore the wrestling and bumping motion of the human body is achieved.
External force as referred in the technical scheme varies with selection of different power machines. The external force comprises various types such as the external force generating from the power machine formed by motor driving a change gear set, the hydraulic pressure being external force generating from the power machine formed by motor driving an oil pump, and the external forces generating from the power machine formed by motor driving a gear reducer, from the power machine formed by variable frequency motor and from the power machine formed by variable frequency motor driving the gear reducer.
‘In a drive mode’ as referred in the technical scheme means that the drive mode varies with the drive component as required for different products, and features non-determinacy. The drive modes comprises various types such as crank link drive produced by the drive component that is formed through the application of lever principle and the crank link mechanism driving the lifting frame, electric-hydraulic pusher drive produced by the drive component that is formed by electric-hydraulic pusher driving the lifting frame, and chain drive. The chain drive is produced by the drive component that is formed in a manner the hook drives the lifting frame to raise and fall down via stretching in or exiting the chain hole.
In crank-link drive mode, power is inside-out transmitted to the power transmission arm via a jack in the fly wheel structure by the power output shaft, which is contrary to bicycle fly wheel drive; the positional structure of the power transmission arm in connection with the power output shaft is formed by bearing together with fly wheel structure, with the bearing at one side functioning in weight and shock carrying, and the fly wheel structure at the other side for directional drive to facilitate fast motion without resistance when directional speed is more than drive speed so as to be favorable for fitting with the motion of the falling body while guaranteeing from returning.
In chain drive mode, power transmission is completed by chain driving the hook of the lifting frame; the hook of the lifting frame is similar to a ‘latch’ being pushed forward by the spring; the ‘latch’ is able to slide to and fro in ‘latch sleeve’ and the ‘latch sleeve’ is fixed on the connecting rod of the lifting frame to directionally fix the latch-like hook so as to ensure the hook mounting into or falling out from chain holes; a protruding point is arranged on upper back of the hook, and the sleeve at corresponding location is also provided with a protruding point; the two protruding points contact correspondingly; a clutch device is imposed on the protruding points; the clutch device is similar to a hand hay cutter, with one end in rotary fixation and the other end being a handle capable of moving up and down around the fixed point; the hand hay cutter body is in a shape of V; after the chain drives the hook to move the lifting frame to a designated height, a regulation point capable of regulating lifting and falling amplitude of the lifting frame in handle direction and located at the designated height prevents the cutter from moving upward so that the cutter move downward to push the protruding points apart, and therefore the protruding points drive the latch hook to exit the chain hole so as to bring the lifting frame to make motion of falling body; when the lifting frame falls down to a designated position, a control point in handle direction also functions in prevention the hand ray cutter from downward motion so that the cutter moves upwards to separate the protruding points and the latch hook stretches into the chain hole under the action of thrust from spring; the chain then prevents the lifting frame from continuously falling down while driving the lifting frame to rise upward, and so reciprocates.
The point capable of regulating the lifting and falling amplitude of the lifting frame can be regulated according to different requirements to the amplitude by different people. In electric-hydraulic drive mode a sensor is added to realize remote-control automation.
To protect the invention against infringement of patent right as far as possible, it is favorable to not restrict the invention on a certain point and so the driving modes are not specified.
The power machine generating the external force, the drive component implementing some mode of driving, the buffer device being served as drive component and the assembly of the support and a protective casing that make up the power system are collectively known as power system.
The power system is used for driving the lifting frame carrying human body to rise to a certain height and then wrestle and bump the lifting frame to a designated plane position; the power system has two modes for driving the lifting frame to move: one mode is up-and-down motion of both ends of the lifting frame at the same time, and the other mode is that one end of the lifting frame is fixed as circle center and the other end is arched up and down around the circle center under the action of external force.
Human body lies in the plane of and in parallel with the lifting frame. Human body is both user and component part of the lifting frame. Once human body lies thereon, the lifting frame operates without bleep that is produced in idle running. The combination of human body with lifting frame is the main structure of the product. The lying postures of human body in exercise can be changed according to exercise requirements or their own needs, such as back lying, side lying and lying on stomach so that the human body can be wrestled and bumped all round.
The lifting frame with two ends being lifted simultaneously under the drive of one crank link is fixed to a more central position of the body builder support by the chain being connected with the support rod; the position is the centre-of-gravity after human body combines with the lifting frame; the lifting frame is only allowed up-and-down motion rather than left-and-right motion. Chain comprises piston chain formed by piston rod and piston bush, guide rail chain constituted by guide rail and sliding block, and roller chain made up of roller and guide rail. The lifting frame with two ends lifting simultaneously may be fixed to four corners of the body builder support.
In crank link drive mode, the buffer device consists of spring and guide slope; one end of the spring is connected to the junction between the connecting rod of the drive component and the support rod, and the other end is fixed to a rotatable disc with steel wire passing through the pulley fixed on the body builder support; the use of the disc can regulate the spring either in looseness or tightness and relieve shock generating from falling body, and/or in combined use of the guide slope the shock is relieved via centrifugal force generating from the guide slope so as to be more conductive to converting buffering force into mechanical power and energy-saving; the guide slope is a circular arc centering on the axle center of the power output shaft of the crank link and having a radius equal to the length that is calculated by adding the distance between the axel center and the crank shaft of the crank link to the radius of a roller centering on the axel center of the crank shaft and rolling on the guide slope; a small section protrudes from the guide opening of the circular arched guide slope; the inner edge of the section is the tangent line of the inner circle of the guide slope.
The overweight person during exercise requires a little stronger wrestling and bumping strength while the lean person needs a little weaker wrestling and bumping strength correspondingly. This product drives human body to do the motion of falling body after rising, and therefore the law of universal gravitation is applied to the operating principle of the body builder. As a result, the overweight person is subjected to a little stronger wrestling and bumping strength of falling body, while the lean person suffers from a little weaker wrestling and bumping strength. That is in case the lifting and falling amplitude is the same, the wrestling and bumping strength suffered by the exerciser varies with weight. The wrestling and bumping strength is also associated with the lifting and falling amplitude, whereas the lifting and falling amplitude is in relationship with the length of the crank.
The wrestling and bumping strength can be regulated by controlling the lifting and falling amplitude; the optimum effect on regulation of lifting and falling amplitude can be achieved by adapting the looseness and tightness of fabric pocket of the lifting frame to the amplitude of the drive system via regulating. In crank link drive mode, the lifting and falling amplitude can be regulated by controlling the regulation point of the lifting frame; in electric-hydraulic drive mode the lifting and falling amplitude can be regulated by controlling the sensor that is used for amplitude regulation. ‘A certain height’ as referred in foregoing technical scheme refers to an indeterminately adjustable height for adaption of the wrestling and bumping strength to the requirements of different people.
The lifting frame has two types consisting of soft and hard bodies; the soft lifting frame is usually used in uplifted and suspended wrestling and bumping, with the designated surface plate where the lifting frame is wrestled and bumped at is fixed and free from up-and-down motion along with the movement of human body; the hard lifting frame is generally used in up-thrown wrestling and bumping at a certain speed and inertia required; the designated surface plate where the lifting frame is wrestled and bumped at is the hard lifting frame itself which moves up and down along with the motion of human body.
Wrestling and bumping frequency can be co-regulated via variable frequency regulation of power motor and size regulation of the driving wheel; both can be used separately.
The invention has the beneficial effects that the exercising in upright posture is converted into that in lying flat on back so as to avoid from organ prolapsed, a highly difficult exercise is simplified and popularized, thereby facilitating to spread, and the exercise is turned from energy consumption into energy absorption, achieving brawny rather than flabby body building without strength exerting and with less sweating. Besides, national physical exercise is promoted and physique is improved, keeping illness away.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Taking one of the power systems of the invention for example, the power plug 115 of the power system 100 is plugged in (see FIG. 1). This is a power system 100 employing the motor 111 to drive gear reducer 112 as power machine 110 and the crank link as the drive component 120. The power machine 110 is put into operating state as the power switch is turned on or the power plug 115 is connected to the power directly, and then the gear reducer 112 generates crank link drive via the drive component 120 to pass the power generating from the motor 111 on the lifting frame 200 or 210. At this time the needed external force gets ready. The user may lie down on the lifting frame 200 now (see FIG. 2). After properly lying down by self-identification or under the guidance of the technical personnel, the user may hold the remoter of the control system or the switch 116 to start up the lifting frame by pressing the switch button, and regulate the wrestling and bumping frequency and amplitude to a state as required. As shown in FIG. 1, the power machine 110 drives the fly wheel via the junction between the power output shaft 114 and the power transmission arm 126, the power transmission arm 126 driven by the fly wheel drives the crank link 124 via the shaft junction 125 between the power transmission arm 126 and the crank link 124, and the crank link 124 transmits the external force through driving the connecting rod 122 to the lifting frame 200 so that the lifting frame 200 carrying human body is able to move from up and down. The connecting rod 122 is preset with screw hole 121. The screw hole 121 is in butt joint with the preset hole in middle of the rail 501 of the support rod 500, and fixed with screws (see FIG. 2). The support rod 500 is in abutment with the preset hole of the lifting frame via the preset holes of the rods in middle and on both sides, and fixed with screws. The rods on both sides are in abutment with the rod in middle via the preset holes, and fixed with screws.

The preset hole on the lower part of the middle rod of the support rod 500 is provided with sliding block or roller 512 that are movable with the lifting frame. The middle leg of the support, which is fixed and irremovable, can be used as roller guide 513 directly or provided with slide guide rail 513, and connected with the movable sliding block or roller 512 to form the chain so that the lifting frame 200 is fixed stably and only allows up-and-down motion rather than left-and-right motion. The fabric pocket 201 is provided on the framework 202 of the lifting frame, and allows releasing and tightening regulations. The length of the power transmission arm 126 can be regulated via the amplitude, and the motor 111 can be variably regulated via the frequency. The wrestling and bumping surface plate can be added with a spacer if necessary, but for majority of young people addition of a spacer is unnecessary. In crank link drive mode, the buffer device consists of spring and/or guide slope; one end of the spring is connected to the junction between the connecting rod 122 of the drive component and the rail 501 of the support rod, and the other end is fixed to a rotatable disc with steel wire passing through the pulley fixed on the body builder support 400; the use of the disc can regulate the spring either in looseness or tightness and relieve shock generating from falling body, and/or in combined use of the guide slope the shock is relieved via centrifugal force generating from the guide slope so as to be more conductive to converting buffering force into mechanical power and energy-saving; the guide slope is a circular arc centering on the axle center of the power output shaft 114 of the crank link and having a radius equal to the length R (half of current amplitude) being calculated by adding the distance between the axel center 125 and the crank shaft 124 of the crank link to the radius r of a roller centering on the axel center of the crank shaft and rolling on the guide slope; a small section protrudes from the guide opening of the circular arched guide slope; the inner edge of the section is the tangent line of the inner circle of the guide slope. The buffer unit not illustrated and invisible is fixed spring buffer. It should be noted that the safety shields around the lifting frame are removed for the purpose of visual and accessible view. The safety shields are only used to prevent from formation of scissors-shaped opening between the lifting frame and the wrestling and bumping surface plate, and intrusion of foreign objects. The user takes no any risks due the use of the fabric pocket.
In the embodiment, the technical scheme of the product is that the lifting frame 200 carrying human body is lifted to a designated height via the drive component 120 under the action of external force generating from power machine 110 in crank link drive mode, and then falls down to a designated wrestling and bumping surface plate 300 after doing a motion of falling body so as to realize wrestling and bumping exercise of human body.
As such, a wrestling and bumping training exercise in lying flat status without prolapsed organs is obtained. One can image what changes the exercise may bring to human health.
FIG. 2 shows the wrestling and bumping being lift from bottom, and FIG. 3 illustrates the wrestling and bumping being lift from side. As shown in the FIGS, an electro-hydraulic power system 110 is selected as the power system 100. The lifting frame is driven by the electro-hydraulic pusher 1144 being pushed by the hydraulic pressure generating from the hydraulic pump 1122 under the drive of the motor 111, and controlled for amplitude and frequency with an automatic control system, so as to realize wrestling and bumping motion. FIG. 4 is the schematic diagram of the soft lifting frame with one end being lifted to wrestle and bump. The stationary shaft of one end of the lifting frame is the circle center of the other end of the lifting frame arching up and down around thereof. At the same time, the stationary shaft also works on balancing and stabilization of the lifting frame. FIG. 5 shows the up-thrown wrestling and bumping of the hard lifting frame. The designated surface plate where the lifting frame is wrestled and bumped at is the hard lifting frame which moves up and down along with the motion of human body. The lifting frame may also be fixed and balanced by the piston rod 5133 that is fixed on the framework of lifting frame and moves with the motion of the lifting frame and the immovable piston bush 5111 being fixed on the support. The wrestling and bumping types of the soft lifting frame may also be divided into uplifted wrestling and bumping as shown in FIG. 2, FIG. 3, and FIG. 4, and uplifted and suspended wrestling and bumping as shown in FIG. 6. The designated surface plate where the lifting frame is wrestled and bumped at is stationary and invariant with up-and-down motion of human body.
Uplifted and suspended wrestling and bumping as shown in FIG. 6 may not need a surface plate at a designated position. Any ground or floor selected at random or any other horizontal plane without sundries is allowable. The stand bar 421 is retractable inside the support leg 411, so is the connecting rod 122. The stand bar 412 is provided with wheel 413 convenient for moving. The lifting frame 200 can be directly connected with the connecting rod 122 through the square interface 1210, rather than through the chain. The square interface can prevent the lifting frame from leaning to one side so as to keep it parallel with the plane where the lifting frame will be wrestled and bumped at. The lifting frame allows being assembled and disassembled at any time. FIG. 6 is one of various types of uplifted and suspended wrestling and bumping, and other types will not be detailed herein.
The technical scheme of the product has a number of embodiments, and others will not be enumerated herein.
Finally, it should be noted that the foregoing embodiments are provided by way of examples only for description of the technical scheme of the invention, and are not intended to limit the scope of the invention.
