The present invention pertains to a fitness device in the form of an article of clothing according to the preamble of claim 1.
Fitness devices of this type are known—under various designations—from U.S. Pat. No. 726,791 (D1), U.S. Pat. No. 4,230,114 (D2) and WO 01/52787 (D3). The present invention and the related state of the art are based on the notion that the blood circulation, particularly of the subcutaneous fat tissue—that usually has an inferior blood circulation, can be improved by subjecting certain sections of the human body to a slight external vacuum. If the metabolic rate is simultaneously increased by means of physical activity, more fat tissue can be metabolized due to the improved blood circulation. For example, the vacuum can be applied by arranging a stationary training device, e.g., a bicycle ergometer or a treadmill, in a vacuum chamber, wherein persons interested in this type of training under vacuum conditions enter the vacuum chamber that typically accommodates the body to a height above the hips. An elastic and airtight seal adjoins the body above the hips. Training devices of this type are known, for example, from U.S. Pat. No. 5,133,339 and EP 0 906 774. However, such stationary systems are quite costly and the users need to frequent the facilities, in which these systems are installed. In addition, the athletic or, in more general terms, physical activity is extremely limited. These disadvantages were at least partially eliminated with the devices described in D1-D3.
The main disadvantage of an article of clothing that should serve as a replacement for a stationary system of the above-described type can be seen in the fact that such an article of clothing needs to contain an airtight outer skin. When a negative differential pressure referred to the atmospheric pressure is generated within this outer skin by means of a stationary (D1, D2) or portable (D3) air pump, the atmospheric pressure acts upon the entire partially evacuated surface of this article of clothing such that it is pressed against the body surface. This decisively impairs the evacuation of the space between the article of clothing and the body surface.
This is taken into account with the spacers claimed in D1 and D3. These spacers are realized rigidly in D1 and consist of pressurized tubular pneumatic elements in D3. However, these spacers act as reinforcing ribs together with the outer skin that is subjected to the differential pressure. Such reinforcing ribs impair the athletic or, in more general terms, physical activity of the wearer. Despite these known spacers, it is still possible for the outer skin to locally adjoin the body surface such that the function of this article of clothing, namely an improvement in the blood circulation of the subcutaneous fat tissue, is not achieved at all locations.
The present invention aims to disclose a spacer that eliminates the aforementioned disadvantages and makes it possible to simplify the overall design of the article of clothing and the corresponding pump unit while simultaneously lowering the costs substantially.
This objective is attained with the characteristics disclosed in the characterizing portion of claim 1, wherein other advantageous embodiments of the invention are disclosed in the dependent claims.
The invention is described in greater detail below with reference to the enclosed figures. The figures show:
A connection piece 3 for a vacuum hose 4 is arranged at a suitable location of the outer skin 1. This vacuum hose leads to a portable, battery-operated vacuum pump that is preferably accommodated in a pouch 5 with a strap 7. The aforementioned vacuum pump is rated such that it can generate and maintain a differential pressure between 10 and 50 hPa referred to the atmospheric pressure at the expected leakage rate of the sealing edges 6. The strap 7 is designed for wearing the pump over the shoulder or for attaching the pump to the body in another suitable fashion. Articles of clothing with a complex shape or for ensuring a uniform vacuum over the entire body surface in question naturally may also comprise two or more connection pieces 3, as well as a corresponding number of vacuum hoses 4 or, if so required, one branched vacuum hose 4.
The outer skin 1 and the spacing layer 2 are respectively cut ready-to-wear into the respective shape and size of the article of clothing such that they can be washed separately. Since the two parts 1, 2 are connected by simply folding the outer skin 1 inward, no connecting elements need to be disengaged in order to clean the article of clothing. If a suitable cut is chosen for the spacing layer 2, it can be ensured that only a small selection of ready-to-wear sizes is required.
The spacing layer 2 provided easily makes it possible to arrange sensors for monitoring certain functions of the person wearing the article of clothing. Such sensors may be provided, for example, for measuring the skin temperature at different locations, the conductivity of the skin, the pulse or the breathing rate, wherein the latter can be determined, for example, based on the tension in the abdominal region of the article of clothing. These sensors may be connected to a suitable data collecting device that is also accommodated in a pouch 7 and supplied with power by the same battery as the vacuum pump according to the invention. This indicates that the fitness device in the form of an article of clothing can also be utilized as a measuring and monitoring device in the field of sports medicine, namely because the athletic activity—particularly with respect to endurance sports—is hardly restricted by the article of clothing. In addition, costly and restricting telemetry devices can be eliminated by providing a suitable data collecting device.
