    Abstract: An adjustable spring loading mechanism for use in controlling the movement of doors and the like. The mechanism includes a cylinder housing and a piston slideable within the housing. An adjustable biasing mechanism selectively increases the load on the springs in the cylinder. The mechanism comprises a plurality of biasing means in the housing in engagement with the piston and arranged to apply individual biasing forces to the piston which cooperate to produce a total resultant force. Load adjustment means are engaged with each biasing means to vary the individual biasing forces to thereby proportionately vary the resultant force.

    Abstract translation: 用于控制门等的运动的可调弹簧加载机构。 该机构包括可在壳体内滑动的气缸壳体和活塞。 可调节的偏置机构选择性地增加了气缸中的弹簧的负载。 该机构包括在壳体中与活塞接合的多个偏压装置,并且被布置成向活塞施加单独的偏压力,该活塞协作以产生总合力。 负载调节装置与每个偏置装置接合以改变各个偏压力,从而相应地改变合力。
