摘要： A seat cushion features an inner core of an open-celled compressible foam material hermetically sealed within a first inner cover which is of a size to fit loosely about the inner core. An outer cover is of a size and shape substantially as that of the inner core and is nominally larger to allow the material of the inner cover to shift within the space between the inner core and the outer cover. A tube incorporating a valve leads from the space within the inner cover through the covers to the atmosphere. The cushion is naturally self-inflating when the valve is open so need not be blown up by the user with this or her lungs or other air source. A sitter on the cushion can adjust its compressibility by opening the valve, or deflate the cushion entirely for storage or for portability, then close the valve to maintain the cushion deflated.
摘要翻译：座垫具有气密密封在第一内盖内的开孔可压缩泡沫材料的内芯，该第一内盖的尺寸适于松动地配合在内芯上。外盖的尺寸和形状基本上与内芯的尺寸和形状相同，并且通常大于允许内盖的材料在内芯和外盖之间的空间内移动。包含阀的管道通过盖子从内盖中的空间引导到大气。当阀门打开时，衬垫自然是自膨胀的，因此使用者不必用这个或她的肺或其他空气源吹起垫子。垫子上的保养人员可以通过打开阀门来调节其压缩性，或者将垫子完全放空以便储存或便于携带，然后关闭阀门以保持垫子放气。

摘要： A weight lifting machine substitutes a noncumulative force or constant tension type spring for some of the individual weights with which the machine would otherwise be equipped, the tension required to unwind the spring being equal to the sum of the omitted weights. The remaining individual weights function as before but when additional resistance, greater than their sum, is wanted, the spring is connected into the lifting mechanism.

摘要： The typical helical springs used to support the bed within the frame of a trampoline or the like are modified to incorporate adjustable hooks threadedly anchored within the springs at one end so that their overall length, and thus the tension on the bed, can be varied and overstretching accommodated. Two principal versions are disclosed, the more preferred one including an additional inner spring biasing the adjustable hook to a retracted position.

摘要： A pair of cushions are hinged to each other and also hingedly attachable to retractable bleachers such that the cushions hang down to form a wall of protective padding over the front of the bleachers when retracted, but when the bleachers are extended the cushions can be flipped-up on top of the seats for spectators to sit on.

摘要： A runner traverses a long distance by running back and forth over a short pathway or lane laid out on a floor and at each end of the lane reverses his direction by partially turning just before striking one of a pair of resilient backstops, each pair having an inverted U-shaped frame, placed at the ends of the lane. In other cases a backstop may be used at one end only of the lane, the runner thus traversing the lane only twice. Each backstop, due to its angle with the floor, rebounds the runner back in the opposite direction at substantially the same speed at which he struck the backstop. In these manners and with such apparatus not only can longer distances be effectively run over relatively short lengths of gymnasium floor, for instance, but various types of foot races can also be conducted indoors.
摘要翻译：跑步者通过在布置在地板上的短路径或车道上来回移动很长的距离，并且在车道的每一端通过在撞击一对弹性后挡块中的一个之前部分转动来反转其方向，每对具有倒U形框架，放置在车道的两端。在其他情况下，仅在车道的一端可以使用止回器，因此，跑道仅穿过车道两次。每个后挡板由于其与地板的角度，以相同的速度以相反的方向在相反的方向上弹回到后挡板。以这种方式，通过这样的装置，例如，可以在比较短的健身房地板上有效地延长距离，但也可以在室内进行各种类型的脚踏。

摘要： A form of trampoline apparatus for use in connection with tumbling and the like employs a relatively long-narrow bed resiliently suspended between a pair of side rails only so that the two opposite ends of the bed are unobstructed by any cross rails or other structure. The two rails are supported above the floor by a substructure which interconnects them and holds the rails apart against the tension of the bed. One end of the bed inclines upwardly toward the remainder of the bed which is horizontal with respect to the floor. The trampoline is narrower relative to its length and having dimensions such that the length is substantially three times or more its width to provide directional rebound characteristics.
摘要翻译：一种用于与滚筒等结合使用的蹦床装置形式使用弹性悬挂在一对侧轨之间的相对较长的狭窄床，仅使床的两个相对的端部不受任何交叉导轨或其它结构的阻碍。两个轨道通过底座支撑在地板的上方，底座将它们相互连接并将轨道抵靠床的张力保持在轨道上。床的一端向上倾斜到床的相对于地板水平的其余部分。蹦床相对于其长度较窄，具有使其长度基本上为其宽度的三倍或更多的尺寸以提供方向性回弹特性。

摘要： The hooked ends of the springs or like members by which the bed of a trampoline or similar apparatus is suspended from its frame are equipped with protective sleeves of flexible material. The sleeves are split at their outer ends to form two flaps, one of which covers the exposed ends of the hooks to prevent injury to a performer inadvertently striking them, while the two flaps together are foldable back onto the sleeve to assist hooking and unhooking of the springs to and from the bed and the frame.
