摘要:
An exercise device (1), for example a dumbbell or barbell, for weightlifting and other fitness activities comprises a lifting bar (2) having an axis (3) and opposed axial ends, and a pair of weight sections (4) mounted spaced apart on the respective opposed axial ends of the lifting bar (2). The lifting bar (2) extends between the spaced apart weight sections (2) defining a handle (5). Each weight section (4) has an outer circumferential surface (8), an inner axial end face and an outer axial end face (10). The circumferential surface (8) of at least one of the weight sections (4) comprises a plurality of grooves (12; 12a,12b,12c), preferably arranged in set (13,14) on diametrically opposed sides of the weight section (4), each extending generally circumferentially around only part of the outer circumferential surface of the weight section (4) and spaced substantially axially from an adjacent groove (12; 12a,12b,12c) axially along the outer circumferential surface of the weight section (4). The sets (13,14) of grooves define grip areas on the weight section (4) with there preferably also being recess portion (18,22) formed in the axial end faces (10,11), to enable a user to better grip and lift the dumbbell (1) by the weight sections (4). The outer circumferential surface (8) is also preferably of a barrelled shape to match and fit in the palm of a users hand.

A trampoline (10) includes a bed (14), a base frame (12), a bed suspension assembly (16) that resiliently couples the bed (14) to the base frame (12), and a plurality of legs (20) that are connected to the base fame (12) so as to maintain the base frame (12) above a surface (36). The base frame (12) includes a first side frame (22), a second side frame (24), a first end frame (26), and a second end frame (28). The plurality of legs (20) includes (i) a first leg (20A) that is secured to the first side frame (22) and the first end frame (26), (ii) a second leg (20B) that is secured to the first side frame (22) and the second end frame (28), (iii) a third leg (20C) that is secured to the second side frame (24) and the second end frame (28), and (iv) a fourth leg (20D) that is secured to the second side frame (24) and the first end frame (26). The trampoline can further include a backstop frame (244A) that is mounted on the base frame (12) and that extends in a generally upward direction away from the base frame (12). The backstop frame (244A) includes a substantially straight first lower support member (250) that is coupled to the base frame (12), a substantially straight second lower support member (250) that is spaced apart from the first lower support member (250) and that is coupled to the base frame (12), and a substantially arch shaped upper support member (252) that extends from near a distal end (250B) of the first lower support member (250) to near a distal end (250B) of the second lower support member (250).
摘要:
Sporting items such as soccer balls include a casing region and a graphic region that are defined by enhanced-visibility colors (EVCs) that are substantially complementary. Such EVCs can be selected to avoid colors associated with color confusion in color deficient individuals. In addition, such colors can be selected based on total reflectances to obtain a predetermined luminance contrast. EVCs can be selected based on separations of color coordinate locations using CIE chromaticity coordinates or CIE L-a-b coordinates or otherwise selected. Color selection can include consideration of anticipated viewing backgrounds in a general setting, or colors can be customized for a particular location and particular illumination conditions.
摘要:
The objective of the present invention is to provide a stability ball case configured to store a stability ball therein and, especially, having a weight thereon to prevent the stored stability ball from rolling, thereby avoiding a safety accident that may happen when the stability ball rolls and drops, as well as storing the stability ball at a desired place in a safe and convenient manner. Particularly, another objective of the present invention is to provide a stability ball case configured such that a weight can be attached to and detached from a body constituting the case, whereby the weight can be separated from the body when the case is washed, or when the stability ball is carried, thereby enabling the stability ball case to be safely used and stored, as well as being conveniently used.
摘要:
A yoga towel is for use in conjunction with a suitable mat or converter that allows an existing mat to be retrofitted to be used with the present yoga towel. The yoga towel has one or more magnets and/or metal attached, advantageously to its perimeter and/or with a center portion of the towel. A suitable surface such as a yoga mat will have a complementary metal and/or magnet so that when the yoga towel is placed on the yoga mat, the yoga towel through magnetic forces (i.e. attraction) is held in place. Advantageously, in one form, the magnets and/or metal are strips in the yoga towel and/or yoga mat are in the form of flexible strips of magnetic material and/or metal.
摘要:
Systems, devices, apparatuses, components, methods, and techniques for cadence and media content phase alignment are provided. An example media-playback device includes a content output device that operates to output media content, a cadence-acquiring device, a phase-delay calibration engine, a cadence-based media content selection engine, and a phase-aligned media playback engine. The cadence-acquiring device includes a movement-determining device and a cadence-determination engine configured to determine a cadence based on movement data captured by the movement-determining device. The phase-delay calibration engine configured to determine phase delay values for at least one cadence value. The cadence-based media content selection engine configured to identify a media content item based on the cadence determined by the cadence-acquiring device. The phase-aligned media playback engine configured to align the identified media content item to the repetitive-motion activity and cause the media-output device to output the aligned media content item.
