[0002] Heretofore, various types of exercise devices have been known for exercising various parts of the human body. One of the most popular devices which has been provided is an abdominal exerciser device as described in U.S. Pat. Nos. 5,492,520 and 5,577,987. One of the reasons for the popularity of this exercise device is the fact that the head and neck of the user can be supported during an abdominal exercise routine, commonly known as an “ab crunch”. Further, the device is of relatively simple construction and can be easily used.
[0003] Other types of exercise devices have been known such as described in U.S. Pat. No. 5,871,425 that employ resistance means or elastic means that offer a resistance to movement, for example, of an upper back support or a foot restraint during an abdominal exercise.
[0004] U.S. Pat. No. 5,813,957 describes an aquatic abdominal exerciser apparatus that employs an air cylinder pivotally coupled between a cross-bar of an exerciser frame and a connecting bar of a support frame in order to afford a predetermined amount of resistance to the relative movement of the support frame and the exercise frame.
[0005] U.S. Pat. No. 5,624,361 describes the use of a stretching exerciser that employs a hydraulic resistance cylinder that provides resistance to a forward pivoting movement of a back rest member relative to a base. Similarly, U.S. Pat. No. 5,094,450 describes an abdominal exercise machine that employs a viscous fluid resistance cylinder or stacked weights to resist rotation of a chest pad during use of the device.
[0006] U.S. Pat. No. 5,882,284 describes the use of an abdominal exercising device that employs an adjustable belt that is tightened across the abdomen of a user and that is used in conjunction with an abdominal exercise device such as described in U.S. Pat. No. 5,492,520. As described, the belt includes an abdominal pad and elastic cords such that when a user rotates forward in a “crunch” type exercise, the pad in combination with the elastic cords provide direct resistance to the abdomen.
[0007] It is an object of the invention to provide an improved abdominal exercise device.
[0008] It is another object of the invention to be able to obtain a comfortable and effect AB crunch workout employing an exercise device which can be adjusted to the relative strength of the user.
[0009] It is another object of the invention to provide an exercise device with attachments to facilitate an abdominal exercise routine.
[0010] It is another object of the invention to provide an exercise device that allows a user to carry out different types of exercise routines.
[0011] Briefly, the invention provides an exercise device comprising a support frame and a skeletal frame mounted on the support frame for rocking back and forth under a manually applied force from a user between a first position and a second position. The skeletal frame also includes a rest for receiving a body part of the user positioned within the skeletal frame. In addition, the exercise device employs means for dynamically increasing the resistance to rocking of the skeletal frame relative to the support frame from the first position to the second position.
[0012] In another embodiment, the means for dynamically increasing the resistance to rocking of the skeletal frame may be employed as a means for dynamically assisting rocking of the skeletal frame relative to the support frame from a lowered first position to a raised second position.
[0013] Conceptually, the invention is directed to a means which can be added to an existing exercise device to increase the resistance to rocking of the device or to assist in the rocking of the exercise device on a support frame.
[0014] As is known, as the human body conducts repetitive exercises over a period of time, the body adapts to the exercise routine so that further benefits are not obtained by continued use. For example, a user employing an exercise device as described in U.S. Pat. Nos. 5,492,520 and 5,577,987 over a period of time reaches a level where the exercise routine does not further enhance the muscles. In this case, the users have employed weights, as described in the patents, to increase the resistance to rocking of the exercise device and to thereby enhance the exercise routine.
[0015] In accordance with this invention, instead of employing a static weight load to increase resistance, use is made of a means that functions to dynamically increase the resistance to rocking of the exercise device. That is to say, the greater the degree of rocking, the greater the degree of resistance.
[0016] In cases where a user is in a beginner's stage, the user may not have the strength to effect an effective abdominal exercise routine. In these cases, the invention instead of increasing the resistance to rocking, employs the same means to dynamically assist the rocking of the skeletal frame relative to a support frame. In this case, the skeletal frame is mounted on the support frame so that the rest receives the head of a person in a raised position. When the user lies down within the skeletal frame, the user then places his/her head on the rest which is then lowered under gravity against the force of the dynamic means. Consequently, when the user then rocks the skeletal frame forwardly to effect an ab crunch, the dynamic means assists the user in rocking the skeletal frame forwardly. Gravity assists the user in returning to the supine position.
[0017] The means that is employed for dynamically increasing the resistance to rocking may be in the form of a pair of shock absorbers, springs, hydraulic pistons, or the like. In a preferred embodiment, the means for dynamically increasing the resistance to rocking is in a form of a pair of elongated elastic members, each of which is secured to and between the support frame and the skeletal frame. Rocking of the skeletal frame on the support frame from a first lowered position of the skeletal frame to a raised second position causes stretching of the elastic members. Thus, when the pair of elongated elastic members are to be employed as a means for dynamically increasing the resistance to rocking, the two elastic members are placed to one side of the skeletal frame to resist rocking towards the opposite side. When the two elastic members are employed to assist in rocking of the skeletal frame, the two members are secured to the support frame on the opposite side of the skeletal frame.
[0018] In other embodiments, use may be made of springs secured between the skeletal frame and support frame for biasing the skeletal frame in one or the other direction relative to the support frame.
[0019] In accordance with the invention, the exercise device may be used to carry out exercise routines other than an ab crunch routine. For example, employing the means for dynamically assisting rocking of the skeletal frame such that the rest on the skeletal frame is in a raised initial position, the user may place his/her torso, for example, the chest area, on the rest while placing his/her hands on a support surface, such as a floor. Initially, the skeletal frame would rock downwardly so that the rest engages the floor. The user would then carry out a “push-up”. During this time, the means for dynamically assisting the rocking of the skeletal frame assists the user in lifting his/her body. Thus, the exercise device may be employed to extend a push-up routine or to, at least, assist the user in effecting a push-up.
[0020] The exercise device may also be provided with a pair of handles on the skeletal frame, each of which is disposed adjacent to the rest for manual grasping thereof during rocking of the skeletal frame on the support frame. These handles allow the user to hold onto the skeletal frame via the handles rather than another portion of the skeletal frame. This increases the effort required in order to carry out an ab crunch.
[0021] The exercise device may also be provided with a backrest secured to and across the skeletal frame for receiving the shoulders of the user while in a supine position.
[0022] The exercise device may be constructed of multiple parts, which may be interfitted together. The exercise device may be shipped in a flattened position in a suitable container or box. In addition, the exercise device may be taken apart by the user for storage in a compact manner. The exercise device may be supported on any suitable support, for example, the support frame of the exercise device may simply be placed on a floor to be disposed in a horizontal position. Also, the exercise device may be employed on various types of benches to be used while the bench is in a horizontal or angular position.
[0023] Further, it is possible to mount the exercise device on a vertical surface, such as a wall, in order to carry out an exercise routine.
