Abstract:
A device (10) for holding a piece (22) in a bore (24) comprises a cylindrical sleeve (12) constructed to be inserted into the bore and held therein by engagement of its outer surface with an inner surface of the bore, and an annular bead (14) extending circumferentially and inwardly from the inner surface of the sleeve, the bead (14) being disposed to engage an outer surface of a piece inserted into the sleeve. The sleeve and the bead are integrally formed of resilient flexible plastic.
Abstract:
A linear compression latch includes a lever handle linked to a pawl. As the latch is opened, the pawl is initially constrained to move vertically within a carriage. After an intermediate position is achieved, the pawl is constrained to move horizontally within the carriage.
Abstract:
A rivet tie (11) for coupling together two or more objects. In one embodiment, the tie (11) includes a cable tie shank (13) and a pawl nut (15) which are integrally connected together by a break-away (33) attachment member of reduced strength. The cable tie shank (13) includes a tail (17) having a first end (19), a second end (21), a top surface (23), a plurality of ratchet teeth (25) formed on the top surface (23) and an enlarged button end (27) integrally formed onto the second end (21). The pawl nut (15) can be separated from the cable tie shank (13) and includes a top surface (28), a bottom surface (29), an elongated central opening (30) and a flexible pawl (31) disposed to project into the elongated central opening (30), in use, two or more objects are disposed on the tail (17) of the cable tie shank (13). The pawl nut (15) is then slidably mounted onto the tail (17) so as to effectively sandwich the objects between the enlarged button end (27) and the pawl nut (15), the pawl (31) sequentially engaging the plurality of ratchet teeth (25) on the strap to secure the coupling of the objects together. In another embodiment, the tie further includes a shroud (63) formed onto the top surface of the pawl nut (15) over the elongated central opening (30), the shroud (63) serving to prevent tampering of the flexible pawl (31) when the tail (17) is inserted into and through the pawl nut (15).
Abstract:
The invention described is an energy absorbing bearing with a primary application in the seismic isolation of structure from the ground or parts of other structures. It may also be used to dampen other forces on structures on which it is installed. The bearing consists of end plates separated by a laminate of resilient and stiffening layers. In a preferred embodiment there is a plastically deformable insert within the laminate. The laminate interfaces with the end plates in each bearing are secured near the central axis from end plate to end plate, but not near the peripheries. The advantage provided is allowing a wider range of forces to be absorbed than with known bearings of this type. Also described are novel laminae and novel means for securing the laminae and end plates.
Abstract:
A fastener assembly (10) includes an elongated tubular body (12) having a face plate (14) at its proximal end. The tubular body (12) defines an axial cavity dimensioned to receive a support member. When inserted into a properly dimensioned hole formed in a support structure, for example a wall, the rear face of the face plate (14) contacts the portion of the support structure surface which surrounds the hole. The tubular body, and the support structure received therein, is maintained in position by an anchoring member (24) disposed proximate the distal end of the tubular body. The anchor member comprises a base portion (26) defining a central, threaded aperture (28). A plurality of elongated wings (30), bendable in the direction of the tubular body, extend from the base portion (26) in a direction toward the face plate (14). A threaded member (22), inserted into the threaded aperture (20), is rotated to draw the wings (30) into contact with the inside surface of the wall panel.
Abstract:
An arrangement for attaching an element (10; 22) having a cylindrical part (11; 23) to a body (12; 21) having a hole (13) into which the cylindrical part can be axially inserted. Either the cylindrical part (11; 23) or the body (12; 21) has a ring-groove (14) in which there is placed a toroidal helical spring (15) whose dimensions are such as to prevent axial movement of the cylindrical part (11; 23) in the hole (13). When the spring turns are forced to one side by rotation of the cylindrical part (11; 23), the turns are accomodated in the ring-groove (14) and therewith allow the cylindrical part (11; 23) to move axially in the hole (13).
Abstract:
An improved anchor assembly (10) for retaining an elongated fastener member within an opening defined by a wall portion having at least one concealed side. Such devices typically comprise at least two elongated leg members (11), means 14) for connecting a pair of adjacent end portions (13) of the leg members (11), an apertured anchor member (18) coupled to the legs (11) at opposite end portions (16) and a collar member (22) secured to the legs (11) for sandwiching the wall portion between the collar (22) and the anchor member (18). The improvement comprises providing each of the legs (11) with respective coupling studs (17) aligned along their major transverse dimensions for engaging substantially longitudinal flanges (20) from anchor member (18) on either side thereof for attaching the legs (11) across the minor dimensions of the anchor (18).
Abstract:
La invención se refiere a un piso modular de alta resistencia, formado por dos o más módulos de piso acoplados y asegurados entre sí. Además, la invención se refiere a los módulos de piso y a un conector curvo para asegurar entre sí módulos de piso acoplados. El piso modular de alta resistencia es versátil y ajustable para diversos usos industriales y comerciales, y está formado por módulos de piso de alta resistencia acoplados y asegurados entre sí por uno o más conectores curvos, que restringen el movimiento relativo entre módulos de piso acoplados en los tres ejes cartesianos.
Abstract:
L'invention a pour objet un dispositif de positionnement de deux éléments selon une position accostée, comprenant des première et deuxième parties (22, 24) comportant respectivement: - des première et deuxième surfaces de contact (30.1, 30.2), - des première et deuxième portions cylindriques de révolution (32.1, 32.2) de forme complémentaire et de même diamètre, - des première et deuxième portions tronconiques de section ovale (38.1, 38.2) qui ont des formes complémentaires de sorte à immobiliser les première et deuxième parties (22, 24) en rotation en position accostée. L'invention a également pour objet un véhicule équipé d'un tel dispositif de positionnement.
