Exerciser

BACKGROUND OF THE INVENTION

[0001] The present invention is related to an exerciser having a main body for a user to lean thereon. A support section is disposed under bottom face of the main body for contacting with the floor. When the main body swings, the user's body will swing along with the main body so that the exerciser can help the user in making various types of exercises.

[0002]
FIG. 7 shows a conventional situp board. An inclined board body 62 is mounted on a frame body 61. Foam sponge rollers 63 are disposed on the frame body 61 for a user's feet to hook and lean thereon.

[0003] In use, the user's feet hook and lean on the foam sponge rollers 63 and the user's body downward inclinedly lies on the board body 62. By means of the strength of the waist, the user lifts the upper half of the body to make situp exercise. When exercising, the user lifts the upper half body all by his/her own waist strength. Such movement is relatively laborious and not so easy for most users, especially for beginners or those users needing rehabilitation. Furthermore, when the user lifts his/her body, the spine and cervical vertebra of the user are not supported and will be bent and arched due to application force of the user. This often incautiously results in injury. Also, the situp board can be only used for situp exercise without other function.

[0004]
FIG. 8 shows another exerciser having a base seat 71. A step board 72 is disposed at one end of the base seat 71 and a seat 73 is positioned at the middle of the base seat 71. A swingable back cushion 74 is pivotally disposed on the base seat 71 and a resilient member 75 is connected between the back cushion 74 and the base seat 71.

[0005] In use, both feet of the user step on the step board 72 with his/her back leaning on the back cushion 74. When the stretching force of both feet of the user exceeds the resilient force of the resilient member 75, the back cushion 74 will swing backward to stretch the user's body. Accordingly, the neck and back of the user are properly supported and the exercise can be made to a greater extent. However, this also is not suitable for those users needing rehabilitation. Also, such exerciser can be used only in a specific manner as aforesaid. Moreover, such exerciser has complicated structure and is manufactured at higher cost and the possibility of failure will be increased.

[0006]
FIG. 9 shows a conventional situp exerciser having an arched main body 8. A pillow 81 is disposed at one end of the main body 8 for a user's neck to lean thereon. The other end is provided with a grip section 82 opposite to the pillow 81 for the user to hold.

[0007] In use, the user's neck leans on the pillow 81 and lies on the floor. When both hands of the user exert a force to push the grip section 82, the ring-shaped main body 8 will swing and the pillow 81 will push the neck upward. Accordingly, the upper half body of the user will be lifted to make situp exercise. When the upper half body of the user is lifted, only the pillow 81 exerts a pushing force on the user. In other words, the weak neck of the user supports the weight of the upper half body of the user. This is very likely to cause injury in exercise. Furthermore, when the user lifts the upper half body, the spine and cervical vertebra of the user are also bent and arched due to the application force. This also tends to result in injury in case of improper force.

[0008]
FIG. 10 shows a swinging exerciser. A shaft 92 is pivotally disposed between two leg supports 91. The shaft 92 is connected with the middle of a back cushion 93. A leg bracket 94 and a pillow 95 are respectively disposed at two ends of the back cushion 93.

[0009] The shaft 92 is connected with the middle of the back cushion 93 so that the back cushion 93 has a form of titter in a balanced state. In the case that one end suffers greater force, the back cushion 93 will turn to the end. In other words, when the body of the user exerts a force on one end of the back cushion 93, the back cushion will swing and the user's body will swing along therewith. Accordingly, the user can easily stretch his/her body without costing much strength. However, the exercising effect will be limited. Moreover, the back cushion 93 has a form of a titter so that it tends to incautiously lose balance and turn. Also, the leg supports 91 have a certain height so that the unbalanced back cushion 93 will turn down to hit the floor by a considerable force. This may hurt the user.

SUMMARY OF THE INVENTION

[0010] It is therefore a primary object of the present invention to provide an exerciser including a main body having a support section disposed under the bottom face of the main body for contacting with the floor. The support section is positioned near one end of long side of the main body to divide the main body into a long part and a short part. In normal state, the main body contacts with the floor in a stable state. When exercising, a user can stably lean his/her body onto the main body and exert a force on the main body by hands or legs to swing the main body. The user's body will swing along with the main body so that the exerciser can help the user in making various types of exercises.

[0011] It is a further object of the present invention to provide the above exerciser in which the support section is arched so that when the main body suffers a force and swings, the arched support section rolls over the floor, whereby the main body simultaneously swings and displaces to more effectively stretch the user's body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0026] Please refer to FIGS. 1 and 2. The exerciser of the present invention includes a main body 1 which is a substantially rectangular board for a user's body to lean thereon. The front and rear sections of two sides of the main body 1 are respectively provided with handles 14 for the user to hold. A support section 11 is disposed under the bottom face of the main body 1 for contacting with the ground. The support section 11 is positioned near one end of long side of the main body 1, whereby the main body 1 is divided by the support section 11 into a long part 12 and a short part 13. In this embodiment, the support section 11 is semicylindrical and has an arched contact section in contact with the ground. When the main body 1 suffers a force, the support section 11 can roll on the floor and the main body 1 is swung along therewith.

[0027] The support section 11 is positioned near one end of long side of the main body 1 so that in normal state, the long part 12 of the main body 1 and the support section 11 will at the same time contact with the floor in a stable state. When a user lifts his/her waist, the upper half of the user's body lies on the main body 1 with the head directed to the end at which the support section 11 is positioned. The user's legs step on the floor with the knees bending. The head of the user is higher than the body as shown in FIG. 3A. Both hands can embrace the chest or hold the handles 14. At this time, the long part 12 and support section 11 of the main body 1 lean on the floor in a stable state, permitting the user to stably adjust the attitude. When exercising, the waist and legs of the user at the same time exert a force to lift the lower half of the user's body. At this time, the gravity center of the user naturally moves to the upper half of the user's body and the head and the short part 13 of the main body 1 suffers a depressing force. With the short part 13 serving as the arm of applied force, the depressing force will relatively create a lifting force onto the long part 12 of the main body 1 as shown in FIG. 3B. Accordingly, the main body 1 will help in lifting the user's body and completing the waist-lifting exercise. Moreover, when the main body 1 swings, the support section 11 rolls, whereby the main body 1 simultaneously displaces when swinging. Therefore, the user's body can more effectively stretch.

[0028] When making push-up exercise, the user lies on the main body 1 with his/her face facing downward and his/her head directed to the end distal from the support section 11. The user's legs step on the floor with both hands straightened on the floor as shown in FIG. 4A. At this time, only the support section 11 of the main body 1 leans on the floor. When exercising, both hands of the user bend, making the upper half of the body depress the long part 12 of the main body 1 and swing the main body 1. At this time, the body of the user swings down along with the main body 1. When pushing up the body, both hands of the user are straightened to lift the upper half of the body. At this time, the gravity center of the user will naturally move backward to create a depressing force onto the short part 13 of the main body 1 and a lifting force onto the long part 12. This helps in lifting the upper half of the user's body and completing push-up exercise as shown in FIG. 4B.

[0029] When making situp exercise, the upper half of the user's body lies on the main body 1 with his/her head directed to the end distal from the support section 11. The user's hip sits on the short part 13 of the main body 1 with the legs stepping on the floor and the knees bending as shown in FIG. 5A. At this time, the gravity center of the user resides in the hip so that the short part 13 and the support section 11 lean on the floor. Under such circumstance, the main body 1 is still in a stable state. When exercising, the user first lies down toward rear side to depress the long part 12 of the main body 1 downward until the long part 12 and the support section 11 lean on the floor. At this time, the gravity center of the user resides in the long part 12 so that the main body 1 is again in a stable state. Thereafter, the user utilizes the strength of the waist to again lift the upper half of the body and again move the gravity center of the body to the short part 13 of the main body 1. Accordingly, a depressing force is exerted onto the short part 13 and the long part 12 is lifted. This helps in restoring the upper half of the user's body back to a position close to sitting attitude as shown in FIG. 5B. At this time, the weight of the user depresses the short part 13 to restore to the previous stable state.

[0030] In the above various types of exercises, the main body 1 is always in a stable state without losing balance and making the user get hurt. Moreover, the support section 11 serves as a fulcrum and the short part 13 or long part 12 serves as the arm of applied force. Therefore, the user only needs to lightly exert a force onto the main body 1, whereby the main body 1 can resist against the weight of the user's body and swing to achieve an exercising effect. Therefore, the exerciser is quite suitable for a beginner or a person needing rehabilitation. When the main body 1 suffers a force, the support section 11 rolls over the floor and the main body 1 is swung and displaced along therewith by a displacement L as shown in FIG. 6. Accordingly, the user's body can more effectively stretch to enhance the exercising effect.

[0031] According to the above arrangement, when exercising, a user can stably lean his/her body onto the main body 1 and exert a force on the main body 1 by hands or legs, whereby the main body 1 can swing with the support section 11 in contact with the floor. At this time, the user's body will synchronously swing with the main body 1. Therefore, the present invention helps the user in making various types of exercises. When the main body 1 suffers a force and swings, the arched support section 11 rolls over the floor, whereby the main body 1 simultaneously swings and displaces to more effectively stretch the user's body.

[0032] The above embodiment is only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiment can be made without departing from the spirit of the present invention.
