Passive exercise bed

A passive exercise bed is disclosed. The passive exercise bed of the present invention comprises a main body, a back fixing unit, a head fixing unit, two arm fixing units, a hip unit, a plurality of extendable units, a plurality of leg fixing units and a control unit. Several driving units are disposed inside the main body and may be activated through the control unit to move or drive the head fixing unit, two arm fixing units, hip unit and extendable units. Therefore, the passive exercise bed of the present invention may be used to stretch out our waist, leg joints, upper body, shoulders, arm joints, elbow joints, wrist joints, the two sides of waist and back as well as hip joints.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention generally relates to a passive exercise bed. More particularly, the invention relates to a passive exercise bed that may be used to stretch out various parts of our body via manual or automatic control and that may provide passive exercise to bedridden, severely ill and disabled people.

2. Description of the Prior Art

Warm-up or stretch-out may reduce or eliminate bodily injuries in exercise or sports because it can prevent sports injuries, lessen the pain caused by muscular stiffness, enhance sports performance and increase the flexibility in tendons and joints as well as prevent the strain-induced tendon inflammation.

Manual laborers are not the only people who are prone to the strain-induced tendon inflammation. Long-term excessive use of the same tendon would cause excessive frictions between the tendon and its surrounding tendons and would cause the strain-induced tendon inflammation. For example, workers who work on a production line and use their hands to assemble products are prone to the strain-induced tendon inflammation because they overuse the same tendon(s). Therefore, the strain-induced tendon inflammation may be regarded as an occupational disease. Also, an ordinary inflammation may be alleviated by ice and may not be alleviated by massage or rubbing. On the other hand, massage and rubbing is needed to alleviate the strain-induced tendon inflammation. Stretching exercise can prevent and cure the strain-induced tendon inflammation.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a passive exercise bed that may be used to stretch out various parts of our body via manual or automatic control.

Another object of the present invention is to provide a passive exercise bed that may provide passive exercise to bedridden and severely ill people.

To reach the objects, the passive exercise bed of the present invention is disclosed. The passive exercise bed of the present invention comprises a main body, a back fixing unit, a head fixing unit, two arm fixing units, a hip unit, a plurality of extendable units, a plurality of leg fixing units and a control unit. The back fixing unit is fixedly connected with and on top of the main body. A user's upper body may lie flat on the back fixing unit with his chest facing up or down. The head fixing unit consists of two fixing parts, which can fix the head in between. The hip unit may support the hip and waist. A handle is provided at the proximal end of either arm fixing unit for the user's hand to grab onto. Several driving units are disposed inside the main body and may be activated through the control unit to move or drive the head fixing unit, two arm fixing units, hip unit and extendable units. Therefore, the passive exercise bed of the present invention may be used to stretch out our waist, leg joints, upper body, shoulders, arm joints, elbow joints, wrist joints, the two sides of waist and back as well as hip joints.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please seeFIG. 1. The passive exercise bed of the present invention comprises a main body1, a back fixing unit2, a head fixing unit3, two arm fixing units4, a hip unit5, a plurality of extendable units6, a plurality of leg fixing units7and a control unit8. Several driving units are disposed inside the main body1and may be activated through the control unit8to move or drive the head fixing unit3, two arm fixing units4, hip unit5and extendable units6. The back fixing unit2is fixedly connected with and on top of the main body1. A user's upper body may lie flat on the back fixing unit2with his chest facing up or down. One or more straps are provided on the back fixing unit2to fix the upper body. The head fixing unit3is disposed on the distal side of the back fixing unit2. The head fixing unit3consists of two fixing parts31, which can fix the head in between. An arm fixing unit4is disposed on either side of the back fixing unit2. A handle41is provided at the proximal end of either arm fixing unit4for the user's hand to grab onto. Either handle41is connected with the driving units disposed inside the main body1. The hip unit5is disposed at the proximal side of the back fixing unit2and can support the hip and waist. The extendable units6are disposed on the proximal side of the hip unit5and are linked to the latter through driving units. A plurality of holes61are provided in the extendable units6so that pins71of the leg fixing units7may be inserted into these holes. The driving units may be hydraulic devices, telescopic devices or transmission devices as long as they can move or drive the head fixing unit3, two arm fixing units4, hip unit5and extendable units6.

Now, please refer toFIGS. 1,2and3.FIG. 2illustrates the passive exercise bed of the present invention in operation. When a user lies flat on the bed with his chest facing up or down, his upper body may be supported by the back fixing unit2and his waist and hip may be supported by the hip unit5. In addition, the straps may be used to fix his upper body and his head may be fixed by the head fixing unit3. Also, the leg fixing units7may be used to fix his legs on the extendable units6and his hands may grab onto the two handles41. Now, the user may use the control unit8to activate the driving units to extend the extendable units6to stretch out his waist and knees. Also, because his head is fixed by the two longitudinally oriented parts31, such longitudinal extension would not twist his neck. Optionally, an additional neck fixing portion may be provided and used so as to extend the neck; in such case, a trained medical person should be present to supervise the process so as to avoid accidents that may hurt the neck. Moreover, the user may use the control unit8to prompt the driving units to move the two arm fixing units4sideways and horizontally so as to stretch out the arms. Furthermore, either handle41may be extended outwards so as to stretch out upper arm joint, elbow and wrist. Because either arm is moved sideways and horizontally as the handle41is extended outwards, the user may let go of the handles41to avoid injuries if any discomfort is generated.

Now, please refer toFIGS. 1,4and5.FIG. 4illustrates the hip unit5and the extendable units6may be moved sideways and horizontally.FIG. 5illustrates that head fixing unit3, the hip unit5and the extendable units6may be moved up and down. InFIG. 4, the straps are used to fix the upper body and the head is fixed by the head fixing unit3; in addition, the leg fixing units7are used to fix his legs on the extendable units6. Then, a user may use the control unit8to activate the driving units to move the hip unit5and the extendable units6sideways and horizontally so as to provide passive exercise to the waist. InFIG. 5, both the head and the waist are moved up and down so as to stretch out the back. InFIG. 6, a user may use the control unit8to activate the driving units to rotate the hip unit5and the extendable units6so as to rotate the waist and stretch out the hip joints.

As previously explained, the passive exercise bed of the present invention may be used to stretch out our waist, leg joints, upper body, shoulders, arm joints, elbow joints, wrist joints, the two sides of waist and back as well as hip joints. Therefore, the passive exercise bed of the present invention may be used for healthy people as well as bedridden and severely ill people.

Although a preferred embodiment of the present invention has been described in detail hereinabove, it should be understood that the preferred embodiment is to be regarded in an illustrative manner rather than a restrictive manner, and all variations and modifications of the basic inventive concepts herein taught still fall within the scope of the present invention.
