## Title
Multi-stage adjustable spring resistant belly massager

## Abstract

A multi-stage adjustable spring resistant belly massager comprises a belly massaging pad, a push-pull rod, a resistance adjusting mechanism and two handle grips. The belly massaging pad rests on the human belly, the push-pull rod is mounted in a barrel to perform the up and down movement, the resistance adjusting mechanism surrounds the push-pull rod and the handle grips are for the player to practice the push-pull exercise on the belly. The resistance adjusting mechanism is composed of a plurality of pulling guides, spring straps, a top decorative cover and a lock ring. The player operates the handle grips to carry out the up and down movement on the belly in one way and rotates the push-pull rod around the belly in other way to accomplish the weight reduction and fat removal in the belly.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a belly massager, in particular the novel multi-stage resistance adjustable belly massager.
2. Description of the Related Art
In most cases, the white-collar workers are doing sedentary jobs, a chair-warmer, deficient of physical exercise; the fat therefore builds up gradually in belly, and lion size become more and more corpulent. Due to the lack of time to take physical exercise and inconvenience to go the gymnastics, the belly massager is the simplest tool to solve the fat building problem on the belly.
FIG. 1 shows a prior art of the belly rubbing exerciser which contains a belly massager 1′, a T form handle 2′ where the belly massager 1′ is a lateral bar 11′ and the T form handle 2′ provides two grips 21′. Between the belly massager 1′ and the T form handle 2′, there installs a resistance mechanism 3′ which composed a pair of lugs 31′ fixed to both side of the upper end of the massager 1′ and another pair of lugs 32′ fixed to both side of the lower end of the handle 2′ with a recoil spring 33′ between two pairs of lug 32′ and locked in place by two pair of lock bolts 331′. When the handle is pressed, the lug 32′ will slide down along the slide groove 12′ on the massager 1′ so as to compress the recoil spring 33′ between lug 32′ and lug 31′. After the pressing is released, the spring will recoil the handle 2′ upward. This downward movement of the handle 2′ will attain the fat partial reduction. However, this single downward pressing movement is very dull, not challengeable and the effect of fat reduction is limited requiring much improvement.
SUMMARY OF THE INVENTION
Viewing from the weak points as mentioned above, the inventor has dedicated for years great efforts to improving the belly massager and finally come up with the multi stage spring assistance adjustable belly massager.
The important object of this invention is to provide a multi-stage spring resistance adjustable belly massager mainly comprising a belly massaging pad, a push-pull rod and a multi-stage spring resistance adjusting mechanism. The belly massaging pad rest on the human belly and the push-pull rod is mounted on the belly massaging pad for carrying out the up and down movement. The resistance adjusting mechanism is housed in the barrel of the push-pull rod to rotating movement. The handle grip is mounted on the top end of the push-pull rod for the player to hold and operate the belly massager. The resistance adjusting mechanism consists of a barrel, a plurality of slide guide, spring straps, a top cover and a lock ring. The combination of symmetrical slide guides with a variety of spring straps offers a variety of resistances to meet the individual choice of each player. The compressing movement of the belly massaging pad attains the fat reduction in the belly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
As shown in FIGS. 2 through 4, the multi-stage spring resistance adjustable belly massager provided in this invention comprises a belly massaging pad 1, a push-pull rod 2, a resistance adjusting mechanism 3 and two handle grips 4, in which the bottom of the belly massaging pad 1 rest closed on the belly. The push-pull rod 2 is sleeved in the belly massaging pad 1 permitting an up and down movement. The resistance adjusting mechanism 3 is housed in the barrel of the push-pull rod 2 for rotation. The handle grips 4 connected to the upper end of the push-pull rod 2 are for the player to hold and operate the belly massager.
As shown in FIG. 3, the belly massaging pad 1 contains two piece of similar half casing 11 locked together with a slide flute 12, the center of the slide flute 12 protruded a rib 13. The push-pull rod 2 contains also two pieces of symmetrical axle 21. At the lower end of the symmetrical axle 21, there is a slide square 22 with a central concave groove 23, permitting the rib 13 of the slide flute 12 to slide along the concave groove 23 in a straight line movement. The slide square 22 has a stop 24 on the top side.
The resistance adjusting mechanism 3 contains a barrel 31, a plurality of slide guides 32, and a plurality of spring straps 33, a top decorative cover 34 and a lock ring 35. The slide guides 32 and the spring straps 33 are housed in the barrel 31 which is sealed by the top decorative cover 34. The lock ring 35 is mounted on the outer edge of the bottom of the barrel 31; the massaging pad 1 and push-pull rod 2 intergraded allowing the push-pull rod 2 rotates inside of the barrel 31. Inside the barrel 31, there is an integral formed of plurality of retaining pillars 311 in equally spaced and diagonally disposed (in reality, there are six pieces of corresponding retaining pillar 311.) The retaining pillar 311 has a flange 312 on the outer edge, the bottom of the retaining pillar 311 also extended to the protruded rib 314 of top of the concave ring differential part 313 of bottom of the barrel 31. The inner wall of concave ring differential part 313 has a protruded rib 315 corresponding to the protruded rib 314.
The number of the slide guides 32 and the spring straps 3 exactly synchronizes to the number of the retaining pillar 311. Each slide guide 32 opens a slide groove 321 on outside of the surface of edge. As shown in the FIG. 5, the slide groove 321 of the slide guide 32 can be corresponding and mounted on the protruded rib 315, so concave ring differential part 313 stop the top of slide guide 32, and the inner wall of the slide guide 32 has a “V” turn clamp 322 to receive the protruded rib 314 of the barrel 31. The bottom of the “V” turn clamp 322 has a retaining pillar 323, and outside of the retaining pillar 323 mounted a protruded stop 324.
So the spring strap 33 hanging firmly on the barrel 31 and between the retaining pillars of 311 and 323 of the slide guide 32, and without slipping off by the stop of flange 312 and protruded stop 324, and permitting the slide guide 32 rotating above the concave ring differential part 313. The concave ring differential part 313 has a flange 325 which maintains a fixed clearance with the retaining pillar 323 on the upper side, this is the clearance allows the stop board 24 of the push-pull rod 2 moves in.
As shown in FIG. 6, the push-pull rod 2 will house in the barrel 31 of the resistance adjusting mechanism 3, allowing the stop board 24 of the push-pull rod 2 to sit in the clearance formed by the flange 325 and the retaining pillar 323 (see FIG. 7) and the slide groove 321 of the slide guide 32 will accept the center rib 13 on the slide flute 12 of the belly massaging pad 1. As shown in FIGS. 8 and 9, while the player push the handle grip 4 and the push-pull rod 2 downward, the center groove of the slide square 22 and the stop board 24 of push-pull rod 2 will fit to receive the center rib 13 of the slide flute 12 in a straight line movement, and the slide guide 32 and spring strap 33 will apply a compressive force on the belly so as to form a partial exercise on the belly to effect the fat reduction.
It is clearly learned that the spring straps 33 of the resistance adjusting mechanism 3 are held between the retaining pillars 311 and 323 of the barrel 31. The resistance adjusting mechanism 3 is designed with at least two pairs of spring straps 33 (Figures show the mechanism of three pairs of spring straps) and each pair of spring strap 33 has different strength, that means each pair of the spring strap 33 produces varying compressive force applied to the belly when the slide guide 32 is in operation. When the resistance adjusting mechanism 3 is turned into the barrel 31, the clearance formed between the flange 325 and the retaining pillar 323 will allow the stop board 24 of the push-pull rod 2 to pass, (see FIG. 6) and the spring strap 33 will recoil back and released. This rotary resistance adjusting mechanism 3 and barrel 31 system attains the multi-stage spring resistance adjustment is a progressive improvement, benefiting both for the industry and the players.
