An agricultural implement is configured to be advanced in a forward direction and includes an implement frame. The implement frame includes a pair of laterally extending fore-and-aft spaced frame members. The frame also includes a fore-and-aft extending interconnecting member that extends between the frame members and presents forward and aft ends. At least one of the frame members comprises a tubular beam presenting forward and aft walls. The forward and aft walls at least partly define an interior beam space, with a window opening being defined in a first one of the walls. The tubular beam receives a respective end of the interconnecting member so that the interconnecting member extends into and out of the interior beam space through the window opening. The respective end of the interconnecting member is welded to a second one of the walls.

An agricultural tool unit includes a tool configured to engage the ground and a mounting device. The mounting device supports the tool and presents a device opening configured to receive the frame member. The mounting device includes driving and driven cam elements, with the driven cam element defining at least part of the device opening. The mounting device further includes a cam element shifter operable to selectively impart relative shifting of the cam elements in a first direction. The cam elements present respective cam surfaces that are complementally shaped and slidably engaged with one another to define a cam interface, with the cam interface extending transversely to the first direction such that the driven cam element is moved in a transverse second direction when the cam elements are relatively shifted by the cam element shifter. The driven cam element is configured to adjustably exert a force against the frame member when moving in the second direction.

A display support system is provide and includes a node connector and a support connector secured to the node connector. The node connector includes a plurality of intersecting planar surfaces that form the outer surface thereof. The support connector is releasably securable to the node connector along one of the plurality of intersecting planar surfaces.

An adjustment device for exercise apparatuses which comprises a flange, a coupling body coupled to the flange by a pressure bar, an adjustment protrusion and a pressure pin, a coupling ring through which the coupling body is passed, a vertical arm connected to the coupling body so as to be adjusted in the back and forth direction and rotationally, and a coupling arm connected to the vertical arm.

Disclosed are tents and tent support frames. A tent support frame includes a rotatable connector and tent support poles. The rotatable connector includes first and second connectors configured to be coupled in a vertical direction with one above another, and rotatable with respect to each other. The first connector includes a first through-hole in a horizontal direction, and the second connector includes a second through-hole in the horizontal direction. Tent support poles include a first tent support pole configured to pass through the first through-hole of the first connector, and a second tent support pole configured to pass through the second through-hole of the second connector.

The present disclosure provides a mechanical structure, including a first link having a first end and a second end, a second link having a first end and a second end, an operative portion, wherein the operative portion comprises a first portion and a second portion unparalleled to the first portion, a connection member connecting the first end of the first link, the first end of the second link, and the first portion of the operative portion, a first protrusion on the second portion of the operative portion, a second protrusion on the second portion of the operative portion, wherein the first link is in contact with the first protrusion and the second link is in contact with the second protrusion when a first angle is between the first link and the second link.

The present disclosure provides a mechanical structure, including a first portion, a second portion, the second portion including a first fixture, and a second fixture over the first fixture, a first connector, the first connector including a first end connected to the first portion, and a second end connected to the second portion, wherein the second end is connected to the first fixture when a first angle is between the first portion and the second portion, and the second end is connected to the second fixture when a second angle different from the first angle is between the first portion and the second portion.

Systems, apparatuses, and methods for constructing an airship quickly and cost-effectively are described. In one embodiments, an airship structure may have a plurality of mainframes, each comprising interconnected pyramid structures. One of the pyramid structures may include an apex joint, four base joints, first connectors, and second connectors. The apex joint and base joints may each have slots configured for receiving connectors. The apex joint may have four apex-to-base slots and each base joint may have a base-to-apex slot and two base-to-base slots. Each of the first connectors may connect the apex joint to one of the four base joints using one of the apex-to-base slots of the apex joint and the base-to-apex slot of that base joint. Each of the second connectors may connect two of the four base joints using one of the base-to-base slots of each of the two base joints connected by that second connector.

A grating for use as shelves for pallet racks or heavy-duty racks, having two longitudinal sides and cross members fitted between the longitudinal sides. The, longitudinal sides are in the shape of a profile in cross section. The profile includes at least a first leg and a second leg arranged substantially orthogonal to the first leg. At least two of the cross members have an open profile, in particular a U- or L-shaped profile in cross section, the open end of which is oriented towards the underside of the grating. Each of these cross members has at least two punched recesses at each end. The first leg of the profile is arranged in each punched recess and is firmly connected thereto via a form- or force-fitting connection method. The first leg of the profile has at least one deformation.

The present invention relates to a device to slidingly connect an end of a first element to a side of a second element, the second element side having a channel extending therealong, the device comprising a device body having a fixable end and a slidable end, the fixable end being adapted to be affixed to the end of the first element, and a protrusion extending from the slidable end of the device body, configured to engage with the channel of the second element and slide therealong, wherein the device body is formed in at least a first and second device body portion, the first and second device body portions being separable.
