BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to an exerciser with a rod along which, with frictional engagement, a back-and-forth motion can be conducted.
BACKGROUND OF THE INVENTION
In a device of this type known from DE-OS 30 32 255, a carriage that is provided with a handle and friction pads is guided slidable on the rod. The rod is fastened to a bottom plate, on which the user is the stand. Such a device is relatively complicated in its construction and also in its use.
OBJECT OF THE INVENTION
The invention has as its object to provide an exerciser that is simpler to produce and to use than the known device; with which, despite this, a greater number of exercises can be performed; and with which the user can vary the load on the muscles at any point in the movement in any way.
SUMMARY OF THE INVENTION
The foregoing object is achieved in an surprisingly simple way in that the rod has, on one end, a rigid T-piece with nonskid, padded legs, and the back-and-forth motion can be performed by grasping the rod. With an exerciser according to the invention, training can be performed in that the rod can be grasped, for example by gloves, with any tightness, and a back-and-forth movement can be performed. Thus exactly those muscles, ligaments, and tendons are stressed that are to be trained. The tighter the rod is grasped, the greater becomes the friction, and thus the load on the parts of the body to be trained. This results in an ideal possibility for spontaneous load regulation and training maximization. The padded T-piece serves, in certain exercises, for bracing on the hips, on the floor, and on the wall, as well as for securing the rod between the legs, with the feet, or the like.
Although in the simplest case the rod can be grasped with gloves, it is also possible that certain friction sleeves of leather or of leatherlike materials can be slidably supported for grasping with the hands.
The frictional heat applied to the rod is a proportional parameter for the training performance produced. To be able to display this training performance in a simply way, it is advantageous if the rod is privided with a device that shows its temperature.
In a simple embodiment, the rod can be coated with a thermoindicator color. In this case, the frictional work which is applied to the rod and converted into heat and which is proportional to the training performance achieved is shown by a corresponding color change.
In another embodiment of the invention, there is placed in the rod a device that converts its linear expansion into an electric pulse, and the electric pulse actuates an optical and/or an acoustic display device.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows an exerciser according to the invention half in section, half in view.
FIG. 2 shows diagrammatically a device that reacts to the thermal expansion of the rod.
FIG. 3 shows the upper part of an exerciser with display and adjustment devices.
FIGS. 4 to 7 show possibilities of use of an exerciser according to the invention.
DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS
The exerciser shown in FIG. 1 comprises a rod 1 that is preferably tube-shaped, that is about 1.5 to 2 m long, and that is connected on one end rigidly to a T-piece 2. The connection occurs here by a nipple 3 on which a bushing 4 that is welded to the rod 1 is screwed. The legs of the T-piece 2 are provided with a padding 5, and caps 6 are inserted into the ends of the T-piece 2. Also, the end of the rod 1 is closed with a cap 7.
An exerciser according to the invention can, for example, be used according to FIG. 4 so that the user climbs onto the T-piece 2 and moves back and forth on it with hands grasping the rod 1. Here it is possible to don gloves, but friction sleeves of leather of leatherlike material to be grasped by the hands can be supported slidably on the rod. Such a friction sleeve 8 is indicated in FIG. 1.
According to FIG. 5, for latissimus training, the T-piece is 2 is braced in the area of the abdomen.
According to FIG. 6, for chest and back-muscle tr
