The present invention relates to a straightly assembled block comprising engaging assembly means configured in male and female types, first ends of which can be coupled to each other, such that male and female piece blocks can be assembled by connecting the same to each other straightly, and the engaging assembly means are improved such that wear is prevented in spite of repeated separation/coupling, thereby maintaining continuous assembly power. To this end, the male and female piece blocks have engaging assembly means, first ends of which protrude in arc shapes, and the second ends of which are coupled to each other. Alternatively, connecting blocks have engaging assembly means formed on both ends thereof in different types. The engaging assembly means formed on the piece blocks or on the connecting blocks comprise a recessed portion and a protruding portion. Each of the recessed portion and the protruding portion has a guide means and a coupling means provided on both coupling surfaces thereof, respectively, the coupling means being guided along the guide means so as to engage, such that the same are connected on the same straight line. An incision hole for an elastic action is formed from a corner of the recessed portion toward the interior, on which a rotating shaft is formed, such that, when the protruding portion is guided and coupled, the incision hole is elastically operated so as to widen the recessed portion in the leftward/rightward outward direction, thereby preventing wear of the engaging coupling means.

Described are base frame assemblies for a passenger seat having an elongated tube and a connector. The elongated tube may include an inner surface, an outer surface, and a connecting aperture extending from the inner surface to the outer surface. The connector may include a first end, a second end, a central opening extending from the first end to the second end, a first stopper at the first end, a second stopper proximate to the second end, a contact surface between the first stopper and the second stopper, and an adjustment slot defined as extending from the first end to the second end. The connector may be positioned within the connecting aperture such that a portion of the elongated tube contacts the contact surface between the first stopper and the second stopper that may together overlap a portion of the inner surface and outer surface of the elongated tube.

A surgical apparatus is provided. The surgical apparatus includes a surgical actuating device including a shaft supporting a first coupling member. The first coupling member includes one or more pairs of apertures. The reload includes a second coupling member including a locking assembly. The second coupling member includes a pair of spring pins positionable within the pair of apertures. The spring pins being movable from an inward position to a radial outward position. The locking assembly includes a lock plate that is moveable from a first position located between the spring pins to a second position spaced from the spring pins. In the radial outward position, the spring pins are received within the apertures of the first coupling member to secure the reload to the surgical actuating member and when the lock plate is in the first position, the reload cannot be separated from the surgical actuating device.

A frame pool is disclosed including a frame assembly and a pool liner, the frame assembly including horizontal frame members and a vertical frame member coupled together via a T-shaped joint. The T-shaped joint may be constructed of plastic to facilitate attachment and detachment to the adjacent frame members and to resist galling and corrosion. The T-shaped joint may also be relatively small to improve the appearance and water containment of the frame pool.

A joint for a swimming pool frame, and a swimming pool including the joint are provided. The joint includes a joint body including a leg pipe holder configured to have a leg pipe of the swimming pool frame inserted into the leg pipe holder. The joint also includes a side pipe holder configured to have a side pipe of the swimming pool frame inserted in the side pipe holder. A locking hole is formed through the side pipe holder. The joint body also includes a locking part including a locking pin configured to extend through the locking hole and through a corresponding connecting hole in the side pipe, thereby holding the side pipe to the side pipe holder.

The present disclosure provides a cable tray assembly comprising a cable tray splice, first cable tray section, and second cable tray section adjacent the first cable tray section with both sections having a bottom wall. The cable tray splice couples to the bottom walls. The cable tray splice may include at least two fasteners and a splice body configured to engage adjacent cable tray sections. The fasteners are configured to couple the splice body to the adjacent cable tray sections and include a spring producing a biasing force against the splice body. The disclosure provides a method to form a cable tray assembly including positioning the two cable tray sections end-to-end, positioning a splice body on bottom walls of the two cable tray sections, inserting a fastener through aligned openings in the splice body and the bottom walls, and applying a spring biasing force to the splice body.

Methods, systems, devices, and products for use in a pole support system. Apparatus include a hinge joint comprising: a base having an insertion end with a longitudinal slot and with a fulcrum protrusion on an inner surface; a cup having a receiving end selectively receiving the insertion end of the base; a securing assembly configured to selectively release the cup from the base, the securing assembly comprising a rotatable shaft that translates along the longitudinal slot between at least i) a lower relative position corresponding to an engaged state in which the insertion end is received by the receiving end, and ii) an upper relative position corresponding to a released state in which the insertion end is free of the receiving end; the shaft having a cam projection positioned to contact against the fulcrum protrusion and displace the shaft toward the upper relative position when the shaft is rotated.

Provided is a leg retention clip for a leg of a tripod and a tripod assembly that includes the leg retention clip. The leg retention clip can be inserted inside a hollow-out inside of a first leg section with slots/holes which output protruding edges of the leg retention clip. When a second leg section is fitted over the first leg section, the protruding edges of the leg retention clip can stop movement of the second leg section and help lock the second leg section in place with respect to the first leg section. If the leg of the tripod includes more than two leg sections, the leg can be provided with multiple leg retention clips.

A device mounting apparatus that allows a device such as a smoke detector or carbon dioxide (CO.sub.2) detector, as well as other device including an alarm, a camera or a light to be selectively positioning at a location on a surface such as a wall. The apparatus comprises a preferably rectangular, hollow rod with rounded corners, and having a first end, second end, and outer surfaces. A device securing bracket that facilitates the attachment of a device to the rod includes a center section with a rod opening, a first side member and second side member, with each member having an angled section and at least one bore. An apparatus to surface securing bracket allows the apparatus to be attached to a surface such as a wall and has a center section with an outward extending first and second side wall, each side wall having a semi-circular segment, with the rod inserted through the space created when the two segments face each other. The apparatus to surface securing bracket also has a rear section with at least one bore through which a screw or other attachment means is inserted. From exiting the bore, the screw enters into the surface/wall, thereby attaching the apparatus to the surface. To maintain the device attached to the device securing bracket, a device mounting pan is utilized. The pan has a rear panel with at least one bore, a center opening for a power wire and a side wall extending outward from the rear panel's perimeter.
