Abstract: A hinge device for a foldable apparatus includes first and second hinge sleeves (20, 70) connected respectively to two parts of the foldable apparatus, a spring member (30) received in the first hinge sleeve, a first disk (50) fitted untreatably into the first sleeve, a second disk (60) fitted unrotatably into the second sleeve and abutting the first disk, a pin (90) sandwiched between the first and second disk, and a shaft (10) combining the first and second hinge sleeves together. The first disk defines a receiving recess (511) to receive the pin. The second disk defines two engaging recesses (621, 622). By opening and closing motions of the foldable apparatus, the second disk rotates relative to the first disk so that the pin received in the receiving recess switchably moves with rotation from one engaging recess to the other engaging recess.

Abstract: A hinge device includes a housing (10), a shaft (20), and a pair of springs (30) coiled in opposite directions from each other. The housing defines a through hole (11) and a slot (14) therein. The through hole includes a large hole (13) and a small hole (12), the large hole communicating with the slot. The shaft includes a first portion (22). Each spring has a free end (34), and forms a plurality of protrusions (32) on an inner surface thereof. The shaft is rotatably received in the through hole of the housing. The springs are frictionally positioned around the first portion of the shaft, the free ends of the springs being retained in the slot of the housing.

Abstract: A captive screw (80) is provided for attaching two sheets together. The captive screw includes a screw (40) and a cap (50). The screw includes a head (41), a threaded shank (43), and a flange (42) located between the head and the shank. The cap includes a cavity (51) and a skirt portion (53). The shank forms a plurality of ribs (52) on an underside thereof. The flange forms a plurality of vertical ridges (44) therearound. The cap and the screw are combined, with the head and the flange tightly fitted in the cavity. The shank extends out of the skirt portion, with cylindrical space defined therebetween. A rod portion of a complementary engaging rivet can then be received in the space.

Abstract: A hinge device of the present invention comprises a male hinge member, a female hinge member and a resilient tube. The male hinge member includes a connecting shaft at one end, a mounting plate at an opposite end and a shoulder between the connecting shaft and the mounting plate. The connecting shaft of the male hinge device forms a receptacle therein for receiving the resilient tube. Four channels are longitudinally defined in the connecting shaft and equiangularly distributed in the shape of a cross to prevent loss of friction in the hinge device. An arcuate surface is formed at each edge of the channels. The female hinge member includes a sleeve and a mounting plate extending from one end of the sleeve, the sleeve having a receiving opening for receiving the connecting shaft of the male hinge member. A longitudinal slot is defined through the resilient tube for enhancing resiliency and allowing expansion of the resilient tube.

Abstract: A fastening device (10) includes a locking pin (12) and an associated pressing clip (14). The locking pin (12) includes a flat head (16) with ring-like shallow (18) therein for easy operational installation of the fastening device (12) unto the heat sink (100) and the PC board (200). A leg section (20) is provided below the head (16), including four locking legs (22) separated from one another by the slots (24) therebetween and extending downward from the head (16). Each leg (22) defines an enlarged tapered section (26) at the distal end with a shoulder section (28) thereabouts for latchable engagement with the back surface (201) of the PC board (200) around the corresponding hole (202) through which the locking pin (12) extends. A ring-like recess (30) is provided on the middle portions of the legs (22) for lowering the insertion force or preventing unnecessary excessive friction during insertion of the locking pin (12) into the corresponding holes (102, 202) of the heat sink (100) and of the PC board (200).

Abstract: A screen combination includes two side beams and an upper beam and a lower beam for securing a panel. The upper and the side beams each includes three flat surfaces intersected with each other. A mortise is formed in each of the flat surfaces. The upper and the side beams each includes two side portions each having a channel for engaging with screws so as to attach accessories to the beams. The upper and the side beams each includes a groove for engaging with the panel. A number of angles are secured to the beams so as to couple the beams together. A number of tenons are engaged with the mortises so as to couple the beams together.
