  • Patent number: 10907363
    Abstract: A floor panel for forming a floor covering comprises a pair of edges provided with coupling parts allowing to couple two of such floor panels to each other by means of a rotation movement. The coupling parts are realized in the form of a tongue and a groove with locking parts. The groove is bordered by an upper lip and a lower lip which comprises a locking part in the form of an upward-directed locking part. The upward-directed part extends over a height which is more than 0.1 times the thickness of the floor panel.

  • Patent number: 5131778
    Abstract: A coupling structure and a method of coupling resin structures wherein a first member is coupled with a thermoplastic second member through a coupling force produced by constricting the volume of the resin during molding and/or the generation of an undercut structure. The undercut structure results from the deformation of a projection member caused by the flow pressure and temperature of the resin. A recess is provided in one of the members. The recess is indented in the laying direction. On the other member, a projection is provided which enters the recess. The coupling of the two members is therefore simple and does not require the use of a subsidiary material. Additionally, when an undercut structure is formed, extremely strong coupling is obtained. Since the undercut is formed by deformation of the projection, no undercut structure is required to be formed on the die, so that no extra cost or burden has to be forced on the die.

The outside plates are produced of a ferrous material except for stainless steel and a film or coating is provided on an outside surface of the outside plates. By virtue of the joining of the outside plates to the frame members and the joining of the outside plates to each other by spot welding, less input heat is required as compared with a continuous welding; therefore, outside plate distortion can be reduced and time and labor for manufacturing of the car body can be reduced. Moreover, since the outside plates are produced of a ferrous material, the painting of the outside surfaces of the outside plates can easily be accomplished.

Upon assembly, the two hooked portions (22,25) are positioned in an overlapping arrangement and a wedge-shaped insert (29) is placed between the hooked end portions (22,25). The wedge-shaped insert (29) is provided with a tapped hole (39,40) at each end in which a wedge retainer or extractor (41) may be attached. Each hooked end portion (22,25) is connected together with two rows of bolts (34,36). A dowel (37,38) is inserted into an aperture (35,36) provided at each interface between the two sections (11,12) to insure precise alignment of the rolling surfaces (13,14) and the thrust surfaces (15,16).

  • Patent number: 4938651
    Abstract: An articulated arm type machine, such as an excavator, has a boom articulated for motion in a generally vertical arc, a stick articulated onto the distal end of the boom, and a tool mounted at the distal end of the stick. The stick is connected to the boom by a quick-disconnect shoe that is rockably mounted at the distal end of the boom and a mating fitting mounted at the proximal end of the stick. A pair of grab hooks on the shoe are used to pick up the stick fitting by hooking onto a grab pin mounted thereon. A set of gear tooth racks on the quick-disconnect shoe intermesh with a corresponding set of gear tooth racks on the stick fitting, and these eliminate play between the stick and boom.

  • Patent number: 4930753
    Abstract: A moldable edge connecting apparatus is disclosed that can optionally be employed as a hinge. It is suitable for use as fencing and is particularly applicable to removable fencing. It employs integrally molded connecting fingers that are designed without deep slots, lips thereover, or fully circumscribed openings to economize on mold manufacturing cost and the expense and difficulty of operating the mold, rendering the invention appropriate to very low cost items. The entire structure is substantially coplanar with segments to be connected, even when used as a hinge, and utilizes half-round grooves that are substantially no deeper than the radius of the groove.

  • Patent number: 4758024
    Abstract: A composite structure comprises at least one ply comprising approximately parallel unidirected twines comprising helically-configured matrix-impregnated continuous strands of filament reinforcements to provide a flanged composite cantilever spring which serves as the principal constituent of a coupling structure. An interior ply of a coupling structure body member comprises unidirected longitudinal twines configured at a body member extremity to provide a flange member connected to a cantilever spring. An exterior ply is disposed transversely of and superimposed upon the interior ply to provide the cantilever spring hinge line. The composite cantilever spring can be constructed to deflect about either a straight or curved hinge line. A preferred tubular form of the coupling structure comprises at least one end configured as a polygonal array of flanged cantilever springs which serve as the socket end of a spring-lock coupling used to connect mating flanged spigot-end structures.

  • Patent number: 4646831
    Abstract: For the directional drilling of boreholes, the orientation of accelerometer modules, magnetometer modules and gyroscopes or other directional sensing devices must be accurately known and maintained with respect to each other and to external mounting devices. This is accomplished by a self-aligning segmented cylindrical connection which accurately maintains modules in rotational alignment with each other for all three directions of rotation, even if the mating surfaces of the connection experience wear due to rough use in the drilling application or repeated calibration in a calibration fixture. Wedged surfaces on each of the male and female portions of the connection constitute the mating surfaces, and are the only surfaces at which the male and female portions contact one another. A depression between the mating surfaces defined by the female portion permits reproducible angular displacement of one portion with respect to the other even if one or both portions are worn.
