Abstract: A hinge pin is temporarily held on a first hinge member on the automobile body by means of a hinge pin support mechanism. A door to be attached to the automobile body is held in position, and a second hinge member on the door is brought into engagement with the first hinge member. The hinge pin is pressed into the second hinge member through the first hinge member to couple the door to the automobile door. The hinge pin support mechanism includes a hinge pin retaining member including a ring separably joined to a plurality of legs. When the hinge pin is pressed into the hinge members, the ring is sheared off from the legs and rides in a peripheral groove defined in the hinge pin. The ring then engages one of the hinge members to prevent the hinge pin from being removed from the hinge members. The door can automatically be attached to the automobile body by a door attaching mechanism and detached from the automobile body by a door detaching mechanism.

Abstract: An easily separable but conventional-appearing hinge wherein the hinge flaps can be connected or disconnected to/from one another without relative lengthwise displacement of the flaps by employing short axial movement of the hinge pin. The flaps thus may be hingedly securely connected together, or disconnected and separated within limited space. The flaps have tubular knuckles with adjacent space or gaps so knuckles of one flap can be interdigitated with knuckles of the other flap and held together by the hinge pin. Knuckles of one flap are slotted longitudinally forming open sided or split tubes; those of the other flap are fully tubular, i.e., unslotted. The removable hinge pin has adjacent cylindrical and flat portions, the latter positionable in gaps longitudinally aligned with the full tube knuckles of one of the flaps.

The spring/actuator when in a first position holds the pin partially extended into the keeper tube. When the leg portions of the spring/actuator are pinched together and into a second position the pin is withdrawn from the keeper tube.

Abstract: First (12) and second (42,62) body portions are each attached to a structural member. The first body portion (12) includes trunnions (18) that are slidably received in corresponding channels in the second body portion (42,62). The second body portion (42,62) includes a base member (62) and a pivot member (42), which cooperate to form the channels. The pivot member (42) has an open position and a closed position. A spring (82) biases the pivot member (42) in its closed position. A lever (44) moves the pivot member (42) against the force of the spring (82) into its open position. When the pivot member (42) is in its closed position, it blocks portions of the channels, thereby locking the trunnions (18) into one of two lock positions in the channels. When the pivot member (42) is in its open position, the trunnions (18) may slide in the channels from one lock position to another or out of the channels to disengage the two body portions.

Abstract: A folding pallet (10) is disclosed which has frame members including upright posts (11,12) base members (16) connecting the front and back posts at their bottoms, top side members (14) connecting the front and back posts (11,12) at their top ends, the top cross rods (17) and bottom cross rods (18) connected to and extending between the vertical posts (11,12) at their tops and bottoms, respectively. A bottom tray (20) is pivotally mounted to one of the bottom cross rods so that it can be moved from a horizontal position covering the bottom of the pallet to a vertical position out of interference with the folding of the various frame members. The vertical posts (11,12) are rotatably mounted to the base members (16) and top side members (14) so that when the tray is lifted up, the pallet can be folded to a flat configuration by drawing a diagonally opposed front post (11) and back post (12) together.

Abstract: A pair of male and female hinge halves fabricated of extruded metal sections having complemental cross-sectional shapes so as to slidingly interfit and interhookingly engage with one another define a longitudinally extending through opening at one transverse side for the reception of a hinge pin, and interhooking means at the opposite side for interhooking engagement with the complementary shape of an extruded metal frame member of a solar collector frame or the like to be adjustably supported. The interhooking engagement between the hinge halves provides a limited movement fulcrum between the two transverse sides serving to clamp the opposite side interhooking means in secure frictional abutment with the extruded metal frame member when the hinge pin is force-fitted into its through opening.

Abstract: A molded hinge mechanism includes a pair of hinge members having open slotted barrel portions which may be molded integrally with the hinge members without the necessity of core inserts or separate drilling operations. The hinge members include at least one pair of interfitting semi-cylindrical surfaces generated about the common axis of the barrel portions which slidably engage with one another as the hinge members rotate relatively about the axis. The slots which contain the hinge pin are open and the slidable interfitting of the semi-cylindrical surfaces prevents the hinge members from separating when the slots are oriented 180.degree. oppositely. Since the semi-cylindrical surfaces do not intrude into the open slots, each hinge member may be molded in a one step operation without the necessity of drilling or inserts.
