    摘要： A system for locking a door can: (1) lock the door in dead bolt fashion, (2) allow the door to open a limited distance, or (3) allow the door to open freely. The system has a door-mounted latch assembly that includes a base plate, an intermediate link pivoted to the base plate, and a mode selection and latching assembly that is pivoted to the intermediate link. The latch assembly also includes a high strength, "T"-shaped latch member, and camming means to slide the latch member back and forth as a control knob is rotated. A latch plate is mounted on the door frame in juxtaposition to the door-mounted latch assembly. The latch plate has a cylindrical portion with a vertical slot for receiving the "T"-shaped latch member. A cylindrical sleeve fits inside the cylindrical portion of the latch plate. Like the cylindrical portion of the latch plate, the sleeve has a vertical slot for receiving the latch member. The sleeve also has a horizontal slot running perpendicular to and intersecting with the vertical slot. When the latch member is engaged in the cylindrical portion of the latch plate, the cylindrical sleeve can be rotated so that the latch member is engaged with the horizontal slot in the cylindrical sleeve. The latch member then cannot be directly withdrawn from the latch plate.

    摘要翻译： 用于锁定门的系统可以：（1）以锁死方式锁定门，（2）允许门打开有限的距离，或（3）允许门自由打开。 该系统具有门安装的闩锁组件，其包括基板，枢转到基板的中间连杆以及枢转到中间连杆的模式选择和闭锁组件。 闩锁组件还包括高强度的“T”形闩锁构件，以及当控制旋钮旋转时来回滑动闩锁构件的凸轮装置。 闩锁板安装在门框上并列到门安装的闩锁组件上。 闩锁板具有圆柱形部分，其具有用于接收“T”形闩锁构件的垂直槽。 圆柱形套筒装配在闩锁板的圆柱形部分内。 类似于闩锁板的圆柱形部分，套筒具有用于接收闩锁构件的垂直槽。 套筒还具有垂直于垂直槽并与其相交的水平槽。 当闩锁构件接合在闩锁板的圆柱形部分中时，圆柱形套筒可以旋转，使得闩锁构件与圆柱形套筒中的水平狭槽接合。 然后，闩锁构件不能从闩锁板直接抽出。

    摘要： A portable, fold-up sports chair includes fabric seat and back portions, attached to and extending between a lightweight, collapsible tubular frame. The transverse frame members are hinged to allow the chair to be folded into a compact bundle for transportation or storage. Straps attached to the underside of the legs help prevent the chair legs from penetrating or sinking when used on a soft surface such as sand. The angle of the seat back is adjustable by means of straps which also serve as arm rests when the chair is in use.

    摘要翻译： 便携式折叠式运动椅包括织物座和背部，其连接并且在轻量级的可折叠管状框架之间延伸。 横框架构件被铰接以允许椅子被折叠成紧凑的束以便运输或储存。 在腿部的下侧附着的皮带有助于防止椅子腿在软表面（如沙子）上使用时渗透或下沉。 座椅靠背的角度可以通过在椅子使用时也用作扶手的皮带来调节。
