    • The spring-loaded camming nut of the invention includes first and second wedge-shaped chock portion. The first chock portion is wedge-shaped and larger than the second. The second chock portion is prism-shaped with a triangular cross-section. Means are provided for moving the first chock portion axially, lateral to the second chock portion. As the smaller second chock portion travels along the larger first chock portion, toward the crack's opening the first chock portion rotates on its horizontal axis, causing a tooth of the second chock portion to move horizontally and upwardly, into the rock.
    • 本发明的弹簧加载的凸轮螺母包括第一和第二楔形轴承座部分。 第一个轴承座部分是楔形的并且大于第二个。 第二轴承座部分是具有三角形横截面的棱柱形。 提供了用于将第一轴承座轴向轴向移动到第二轴承座部分的装置。 随着较小的第二轴承座部分沿着较大的第一轴承座部分行进,朝向裂缝的开口,第一轴承座部分在其水平轴线上旋转,导致第二轴承座部分的齿水平和向上移动到岩石中。

    • The apparatus is for engaging a generally cylindrical borehole, and includes first and second chock portions, the first chock portion being generally spherical, the second being a trough-shaped wedge. The wedge-shaped second chock portion has a thinner end and a thicker end, and first and second primary surfaces. The first primary surface is cylindrically convex and dimensioned to seat flush against the wall of the borehole. The second primary surface is shaped as a concave, inclined trough dimensioned to permit the spherical first chock portion to slide freely therewithin. A primary tether affixed to the first chock portion is used to position the apparatus in the borehole, and includes a loop from which a user's body weight or gear may be suspended. A chock control cable operable with a finger pull bar is affixed to and operable to move the second chock portion in the borehole, lateral to the first chock portion. Sheaths protect and separate the primary tether and the chock control cable from one another. A flattened belt on the outermost surface of the first chock portion aids engagement with the borehole surface. A flattened belt on the first chock portion's inner surface aids engagement with the trough of the second chock portion.
    • 该装置用于接合大致圆柱形的钻孔,并且包括第一和第二轴承座部分,第一轴承座部分大致为球形,第二轴承座为槽形楔形件。 楔形第二轴承座部分具有较薄的端部和较厚的端部,以及第一和第二主要表面。 第一主表面是圆柱形凸起的并且尺寸适于与钻孔壁齐平。 第二主表面成形为凹入的倾斜槽,其尺寸允许球形第一轴承座部分在其中自由滑动。 固定在第一轴承座部分上的主要系绳用于将装置定位在钻孔中,并且包括可以悬挂用户的体重或齿轮的环。 用手指拉杆可操作的阻塞控制电缆固定到并可操作地移动钻孔中的第二阻塞部分,与第一轴承座部分横向。 护套保护并将主系绳和阻塞控制电缆彼此分开。 在第一轴承座部分的最外表面上的扁平带有助于与钻孔表面接合。 第一轴承座内表面上的扁平带有助于与第二轴承座部分的槽接合。

    • A device for displaying an article which comprises a front frame part, a back frame part and a decorative covering over the face of the front frame part and held thereon by reason of clamping engagement of interfitting rims on the two parts with the decorative covering. The parts have aligned openings for viewing the article, such openings being covered by a transparent sheet for protecting the article. Supporting means for the frame assembly is secured to the back part and includes an easel which may have a loop for suspending the frame assembly or includes a stand. The easel or the stand are shaped so as to provide a cavity between it and the back part for receiving the article and the protective sheet.

    • An anchor bolt providing for fall protection. The anchor bolt has an anchoring device that may be of any standard type, for making use of an aperture either in or through a structure as an anchoring point, an elongate flexible member connected to the anchoring device at one end of the elongate flexible member, and a handle connected to a second end of the flexible member. The handle member is pivotally attached to the second end, for pivoting about the elongate axis of the flexible member as it extends from the second end. Preferably, the anchoring device is a novel, toggling type in which a toggling member is pivotally attached to the flexible member at a ball joint.
    • 提供防坠落的锚栓。 锚定螺栓具有可以是任何标准类型的锚定装置,用于利用在结构中作为锚固点或通过结构的孔,在细长柔性构件的一端处连接到锚定装置的细长柔性构件, 以及连接到柔性构件的第二端的手柄。 手柄构件枢转地附接到第二端,用于当其从第二端延伸时围绕柔性构件的细长轴线枢转。 优选地,锚定装置是一种新颖的切换型,其中切换构件在球形接头处可枢转地附接到柔性构件。
