    Abstract: A gas spring is connected between a cabinet and a lift-top lid and releasably holds the lid upwardly in a fully open position with respect to the cabinet. Gravity automatically pivots a safety latch into latching relation with the cylinder of the gas spring as the lid approaches its fully open position. If the gas spring loses pressure, the latch operably engages the cylinder to mechanically hold the lid in its fully open position and to prevent the lid from falling toward its closed position.

    Abstract: A skylight, having a wing actuated by pneumatic springs, can be moved to an emergency opening position thereby substantially exposing the opening area of the skylight case. The skylight also acts as a residential ceiling or attic skylight which has, in the normal open position, a considerably smaller opening than in the emergency open position. A locking device is provided to restrict the long extension stroke of the piston rod of the pneumatic springs to a partial stroke. This partial stroke allows an opening which essentially corresponds to the standard opening of the wing in a residential skylight. The locking device, located on the cylinder of the pneumatic spring, includes a specially designed latch which, in order to effect partial stroke restriction of the piston rod, lockingly engages a stop located on the side of the case by means of a catch pin.

    Abstract translation: 具有由气动弹簧致动的翼的天窗可以移动到紧急打开位置，从而基本上暴露天窗的开口区域。 天窗还作为住宅天花板或阁楼天窗，在正常开放状态下，开放面积比紧急开放位置小得多。 提供锁定装置以将气动弹簧的活塞杆的长延伸行程限制到部分行程。 该部分行程允许基本上对应于住宅天窗中的机翼的标准开口的开口。 位于气动弹簧的气缸上的锁定装置包括专门设计的闩锁，为了实现活塞杆的部分行程限制，锁闩装置借助于卡扣销锁定地接合位于壳体侧面上的止动件。

    Abstract: A gas spring-assisted counterbalance system for a closure member, e.g., the rear door of a hatchback automobile, includes a mechanical spring connected in series with a gas spring. The system is arranged so that the gas spring reaches its fully retracted position before the door is fully closed, after which the door is closed against the force of the mechanical spring. Longitudinal vibrations or short movements of the system which otherwise would impart undesired short stroke cycles to the gas spring are absorbed by the mechanical spring, thereby enhancing the operating lifetime of the gas spring.

    Abstract: A pair of spring-loaded oven door hinge mechanisms, mounted on a domestic range body and located at the lower corners of a counterbalancing oven door lock in a partially open position upon removal of the oven door to preclude accidental tripping of the non-counterbalanced hinge mechanisms. Reinstallation of the counterbalancing oven door unlocks the spring-loaded hinge mechanisms to permit normal oven door movement between open and closed positions. Each hinge mechanism includes a fixed roller normally engageable with a hinge blade projection to provide a broil position detent mechanism. The fixed roller snaps into a deep recess or notch in a movable hinge blade upon removal of the oven door to provide positive locking of the hinge blade to maintain the associated hinge mechanism in a partially open position, thereby facilitating oven door reinstallation.

    Abstract: 946,176. Oven doors mechanism. TAPPAN CO. May 11,1962 [Oct. 10,1961], No. 18287/62. Headings E2F and E2M. [Also in Division F4] A removable drop down door of an oven has counter-balance mechanisms within the door, the oven door 12 comprising glass panels 12 1 , a closing mechanism engaging the catch 14, an outer wall 16, a door liner 17 and one counter-balance and support mechanism on each side of the door. Each mechanism has a U-shaped channel 18, a counter-balance tension spring 19 fixed at one end by a screw 20 and attached at the other to a bracket 21 which slides in the channel 18, a hinge pin 27 fitting in a slot 31 and a support lever 23 pivotally fixed to the bracket 21 and the pin 33. A latch bar may enter the slots 38 and 39, thus locking the bracket 21 when disconnecting the door. The pivot connections at 33 and 27 are formed with open cam hooks so that the door is easily releasable. Sealing means 15 are provided around the frame 13.
