Embodiments of the present invention relate generally to physical training machines, and in particular, to exercise machines commonly referred to a step and jump exercise device.
Whereas people today are more conscious of fitness thanks to the ever-improved living standard, fitness equipment has become very popular. However, some of the fitness equipment emphasizing sit up in bear hands may get too rough and violent resulting in stretch in larger angles that causes injuries to the user having overweighed problem or in middle ages or elder. Furthermore, the sit up may become so monotonous and the user may be disinterested very quickly. Besides, fitness equipment generally available in the market either consumes too much space at home or is very expensive, plus other factors, such as the users in a family whose age, physical strength vary, the confined space available at home, the limit to only one function, and nature and length of training session.
A jump exercise device such as a trampoline is commonly used to exercise one body part of a human body, while a step exercise device is used to exercise another body part of a human body. In order to exercise these two different body parts, a user has to possess two different exercise devices, which sometimes are more expensive and take more storage space.
Embodiments of the invention are illustrated by way of example and not limitation in the figures of the accompanying drawings in which like references indicate similar elements.
Various embodiments and aspects of the inventions will be described with reference to details discussed below, and the accompanying drawings will illustrate the various embodiments. The following description and drawings are illustrative of the invention and are not to be construed as limiting the invention. Numerous specific details are described to provide a thorough understanding of various embodiments of the present invention. However, in certain instances, well-known or conventional details are not described in order to provide a concise discussion of embodiments of the present inventions.
Reference in the specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in conjunction with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase “in one embodiment” in various places in the specification do not necessarily all refer to the same embodiment.
According to some embodiments, a combo exercise device can be used either as a jumping device or a stepping device. An exercise device includes a first tubular frame having a flexible fabric attached thereon, a second tubular frame having a rigid board mounted thereon, and at least three elongate support members disposed between and separate the first tubular frame and the second tubular frame. Each of the elongate members includes a first end fixedly mounted on the first tubular frame and a second end fixedly mounted on the second tubular frame, such that a first cross plane of the first tubular frame is substantially parallel to a second cross plane of the second tubular frame. When the second tubular frame is placed on a substantially flat surface, the exercise device can be used as a jumping exercise device and the flexible fabric mounted on the first tubular frame can be used as a jumping mat. When the first tubular frame is placed on the substantially flat surface, the exercise device can be used as a stepping exercise device and the rigid board mounted on the second tubular frame can be used as a stepping board. In one embodiment, each of the first tubular frame and the second tubular frame includes a circular steel frame and the fabric and the rigid board are in a circular shape fitting within a circular area within the circular steel frame.
In one embodiment, exercise device 100 further includes a strong fabric or cloth 104 (e.g., canvas) stretched and tied to the first tubular frame 101 to form a bouncing mat or bouncing bed. Exercise device 100 further includes a hard or rigid board 105 mounted onto second tubular frame 102. Rigid board 105 may be made of wooden material. The shapes of fabric 104 and rigid board conform to the shapes of first tubular frame 101 and second tubular frame 102, respectively. In this embodiment, both fabric 104 and board 105 are in a circular shape with a diameter slightly less than the diameters of first tubular frame 101 and second tubular frame 102, such that they can fit within interior edges of first tubular frame 101 and second tubular frame 102 without being stretched over or covering tubular frames 101-102.
In addition, exercise device 100 further includes a set of support members or legs 103 distributed substantially evenly along a perimeter of the first tubular frame 101 and second tubular frame 102 to connect and provide support to first tubular frame 101 and second tubular frame 102. In one embodiment, each of support members 103 is fixedly mounted on first tubular frame 101 and second tubular frame 102 substantially perpendicular to a cross plane of first tubular frame 101 and second tubular frame 102, such that the cross planes of first tubular frame 101 and second tubular frame 102 are substantially parallel (e.g., a wheel-like frame or a drum-like apparatus). Similarly to first tubular frame 101 and second tubular frame 102, support members 103 may be in a tubular shape and made of strong or hard enough material (e.g., steel tube, fiber glass) that can support the weight of a typical user. In one embodiment, each of support members 103 is made of a steel tube or steel rod.
In one embodiment, exercise device 100 can be used as either a trampoline or a stepping device. When second tubular frame 102 is placed on a substantially flat surface or support platform (e.g., a floor or ground) as shown in
In one embodiment, exercise device 100 further includes an array of hooks or belt loops disposed substantially evenly on the edge of fabric 104, such as hooks or mesh belt loops 106. Exercise device 101 further includes a string or rope 107 inserted or traveling through an opening of each of hooks 106. The size or diameter of fabric 104 is slightly smaller than a diameter of a cross plane of first tubular frame 101. String or rope 107 is configured to wrap around first tubular frame 101, while stretching and pulling fabric 104 outwardly towards first tubular frame 101 via hooks 106 to form a tension surface. Hooks or mesh belt loops 106 mesh belt loop may be made of a wear resistant and heat tolerance material. Hooks or mesh belt loops 106 may be attached to the edge of fabric 104 using machine sewing. String 107 may include a rubber tube or rubber string enclosed by a wear resistant and heat tolerance material to form a tension rope. The tension rope provides resistance and stores energy when a user steps onto fabric 104. Unlike a conventional trampoline, the configuration as shown in
In one embodiment, exercise device 100 further includes an array of mounting brackets 108 substantially evenly distributed and fixedly attached to second tubular frame 102. Mounting brackets 108 may be welded onto an inner edge or inner surface of tubular frame 102. Rigid board 105 then sits onto the top of mounting brackets 108 and is mounted on the mounting brackets 108, for example, using screws and/or nuts. In this embodiment, mounting brackets 108 are positioned between an interior surface of rigid board 105 and tubular frame 101. In one embodiment, an exterior surface (e.g., the surface away from first tubular frame 101) of rigid board 105 is coated with anti-slippery material, such as rubber, rubber-like, leather, leather-like material, or a combination thereof.
In one embodiment, exercise device 100 further includes a first set of plastic sleeves 111 disposed between the first ends of elongate support members 103 and tubular frame 101. Exercise device 100 further includes a second set of plastic sleeves disposed between the second ends of elongate support members 103. Plastic sleeve 111 includes a mounting hole (not shown) to allow a screw inserted therethrough. Plastic sleeve 111 includes a flat surface facing the first end of elongate support member 103 and a sunken surface or sunken well facing tubular frame 101. The sunken surface or sunken well is conformed to an exterior surface of tubular frame 101 to allow elongate support member 103 to be tightened to tubular frame 101. Similarly, plastic sleeve 112 includes a mounting hole (not shown) to allow a screw inserted therethrough. Plastic sleeve 112 includes a flat surface facing the second end of elongate support member 103 and a sunken surface or sunken well facing tubular frame 102. The sunken surface or sunken well is conformed to an exterior surface of tubular frame 102 to allow elongate support member 103 to be tightened to tubular frame 102. In one embodiment, distance 115 between the cross plane of first tubular frame 101 and the cross plane of second tubular frame 102 is approximately 8 inches. Diameter 116 of each elongate support member 103 is approximately 1 inch.
According to one embodiment, exercise device 100 further includes a set of stands 121 amounted on an exterior side of tubular frame 101 (e.g., away from tubular frame 102). Stands 121 may be made of plastic, rubber, rubber-like, or any anti-slippery material that can provide friction against a support surface (e.g., a floor or ground) when tubular frame 101 is placed on the support surface. Stands 121 will raise or separate tubular frame 101 from the support surface to prevent tubular frame 101 from scratching the support surface, or vice versa. In one embodiment, each of stands 121 includes a near end attached to tubular frame 101 and a far end having a sunken well. The near end of each of stands 121 includes a surface matching an exterior shape of tubular frame 101. Each of stands 121 further includes a mounting hole to allow a screw to be inserted through the sunken well. Each of stands 121 is mounted on tubular frame 101 by screwing a screw onto a screw-threaded hold of tubular frame 101, without exposing the screw outside of the sunken well to prevent the screw from scratching the support surface.
Similarly, according to one embodiment, exercise device 100 further includes a set of stands 122 amounted on an exterior side of tubular frame 102 (e.g., away from tubular frame 101). Stands 122 may be made of plastic, rubber, rubber-like, or any anti-slippery material that can provide friction against a support surface (e.g., a floor or ground) when tubular frame 102 is placed on the support surface. Stands 122 will raise or separate tubular frame 102 from the support surface to prevent tubular frame 102 from scratching the support surface, or vice versa. In one embodiment, each of stands 122 includes a near end attached to tubular frame 102 and a far end having a sunken well. The near end of each of stands 122 includes a surface matching an exterior shape of tubular frame 102. Each of stands 122 further includes a mounting hole to allow a screw to be inserted through the sunken well. Each of stands 122 is mounted on tubular frame 102 by screwing a screw onto a screw-threaded hold of tubular frame 102, without exposing the screw outside of the sunken well to prevent the screw from scratching the support surface.
