A connector may couple to a non-cylindrical composite tubing having at least two lateral sides disposed in parallel and an open end. The connector may comprise first and second bonding plates adhered to an inner surface of the two lateral sides via an epoxy adhesive uniformly distributed. The first and second bonding plates may each have a distal lateral face defining a plurality of first threaded holes accessible at the open end of the composite tubing. The connector may also comprise an end plate having a plurality of first and second slotted holes disposed substantially in parallel and each aligned with an associating one of the first threaded holes. The connector may also comprise end plate fasteners loosely inserted through the first and second slotted holes and engaged with the first threaded holes. The end plate may also comprise one or more attachment points.

A wall mounting bracket for mounting a channel profile element to a wall surface includes a wall plate to be mounted to the wall surface, and at least one support for supporting an end portion of the channel profile element. The support is attached to and extends from the wall plate, The support includes at least one wall portion having fastening apertures. The support includes at least a first support profile and a second support profile. In use the first support profile bears against an exterior side of one of the opposing walls of the channel profile element and the second support profile bears against an interior side of the other one of the opposing walls of the channel profile element.

The present invention provides a connection system for removably connecting first and second pieces one to another. The connection system comprises: a tapering recess formed in, or connected to, the first piece. The tapering recess has an opening which is shaped and dimensioned to receive a wedge formed in, or connected to, the second piece. The wedge has a dovetail profile which is adapted to engage with walls of the recess.

The wedge is shaped and dimensioned to slide in a first direction and thereby wedge into the tapered recess. Each piece has at least one aperture which receives a lock piece. The first and second pieces when connected and which when oriented in a user preferred direction, cause the lock piece to fall from a first aperture into a second aperture, thereby locking the wedge in the tapering recess and preventing movement in an opposite sliding direction.

A mounting device includes a base having an internal cavity, a top, and an open bottom in communication with the internal cavity. The device includes a first upper member above the base, wherein the first upper member extends upwardly from the base, and a second upper member is above the base, wherein the second upper member extends upwardly from the base. The device further includes a fastener opening formed though the base for receiving a fastener when the mounting device is secured to a roof. The fastener opening is in communication with the internal cavity.

A booth module for exhibition includes: a frame; a main body dowel; a bolt detachably coupled to the main body dowel; and a cap dowel detachably coupled to the bolt, wherein the main body dowel has: a body having a bolt insertion hole formed therein; a button of which a part is inserted and installed in the body through a button installation hole formed in the body; and a spring installed inside the body and pushing one end of the button, and wherein the cap dowel has: a body having a bolt insertion hole formed therein; a button of which a part is inserted and installed in the body through a button installation hole formed in the body; and a spring installed inside the body and pushing one end of the button, wherein the buttons are provided with bolt through holes communicating with the bolt insertion holes.

A mounting device including a base having an internal cavity and an upper portion above the base. The upper portion extends upward from the base and includes a vertical member defining opposed first and second faces above the base. An aperture is formed through the upper portion and extends through the first and second faces. The base extends outward, beyond each of the first and second faces.

To provide a fitting member, an annular member, a joined member and a method of manufacturing the joined member, which prevent occurrence of a not-joined portion. A fitting member 10 has a fitting protrusion 10p which is protruded outward on an outside face 10s. An annular member 20 contains a space 20h in which the fitting member 10 is to be fitted. An annular member 20 has an annular protrusion 20p on an inside face 20f. When the fitting member 10 is fitted into the space 20h at a predetermined depth, the fitting protrusion 10p and the annular protrusion 20p fill not-joined portions which may be generated assuming that they are not provided. A joined member 30 is produced by fitting the fitting member 10 into the space 20h at the predetermined depth, so that a contact portion between the fitting member 10 and the annular member 20 is joined in solid phase.

A composite tapered tubular assembly includes a composite tapered tube extending between a first end and a second end and tapered so as to have a smaller radius R1 at the first end than a radius R2 at the second end. The assembly also includes a first internal annular wedge that is in contact with an inner surface of the tube at said first end and a first external annular wedge in contact with the outer surface of the tube at said first end. The assembly further includes a first nut provided at said first end that is configured to be connected to said first internal wedge and a second external annular wedge provided on an outer surface of the tube and a second internal annular wedge in contact with the inner surface of said composite tube at said second end, and a second nut connected to an internal surface.

An assembly to connect a panel to a support member. The assembly may include a saddle fitting configured to connect to the support member and including first and second plates. A back fitting may be positioned between the second plate of the saddle fitting and a second face of the panel. An index fitting includes a flange that may be positioned between the first plate of the saddle fitting and a first face of the panel, and a boss that extends outward from the flange and through the opening in the panel. The index fitting is wider than the panel and sized to fit within the gap of the saddle fitting with a first end of the index fitting contacting against the first plate and a second end of the index fitting contacting against the second plate. One or more fasteners may connect the saddle fitting to the index fitting.

A mounting device including a base having an open bottom, a longitudinal axis, and a linear guide on the base. The linear guide guides support hardware in linear movement along the longitudinal axis. An internal cavity is under the base for containing a sealant against and in cooperation with a roof when the mounting device is secured to the roof. An opening is though the base is for receiving a fastener when the mounting device is secured to the roof. The opening is in communication with the internal cavity. The linear guide extends beyond the internal cavity.
