An electrically powered motor vehicle for transport of goods, of the minivan type, includes a main frame, a front axle assembly and a rear axle assembly. The main frame includes a front frame subassembly, a floor-panel subassembly, a rear frame subassembly, and a top frame subassembly. Each of these frame subassemblies includes a lattice structure including box-section elements made of steel, preferably high-strength steel. Each of the frame subassemblies is prearranged for being preassembled separately and subsequently assembled together with the other subassemblies so as to constitute the main frame. The structure is such as to afford high flexibility of production, and presents at the same time considerable safety characteristics, thanks to a high capacity of absorption of impact energy. The motor vehicle is equipped with a transporting body having a hollow-walled body made of plastic material, filled with foamed plastic material, preferably obtained with the rotational-molding technique.

There is provided a double-skin structure in which it is possible to obtain an aesthetic improvement in addition to restricting an increase in the number of manufacturing steps. The structure includes a connection portion connecting together an end portion of a first projection portion of a first mold member and an end portion of a second projection portion of a second mold member; a cover plate that is provided between the first mold member and the second mold member, and that blocks an upper end side of a recessed portion bounded by a first rib, a second rib, the first projection portion, and the second projection portion; and a bonding portion that bonds the cover plate to the first mold member, and the cover plate to the second mold member.

The present invention discloses a detachable, modular vehicle conversion system with universal adapter couplers and adapters to enable conversion of a vehicle, such as a van, cargo van, or trailer from a single-purpose vehicle to one that accommodates a variety of auxiliary units for camping, mobile offices, or industrial purposes, and which allows the user to switch between different uses. This modular conversion system has components that allow for different configurations that can be readily changed to suit the user's needs.

The invention provides a method of assembling a roof of a cargo body. A plurality of sidewalls are provided, each comprising a side panel and an upper rail coupled to the side panel. A roof panel is located above the plurality of sidewalls adjacent the upper rails. A roof bow extends between the upper rails below the roof panel. The roof bow is fixed to a track of one of the upper rails with a fastener.

A protective rail for a trailer is formed of an extension or ridge projecting outwardly from a wall of the trailer and extending along at least a part of a length of the wall. The protective rail is provided with tie-down anchors for coupling with tie-downs having couplers such as rings, eyes, or loops. The anchors may tongues formed in the protective rail when the protective rail is cut-out at selected locations along the protective rail. The anchors may be sized and shaped such that the surrounding portion of the protective rail prevents or tends to prevent other trailers or objects contacting the protective rail from damaging or becoming caught on the anchors.

A first beam (1) is inserted through a transverse opening (4) in a tubular second beam (2). A bolt (7) is inserted through unthreaded holes (9A, 9B) in the second beam. The bolt may be transverse to both beams. A wedge (5) is threaded onto the bolt inside the second beam (2). Tightening the bolt moves the wedge against a side of the first beam, forcing it against surfaces (11, 12, 13) of the transverse opening (4) opposite the wedge. The bolt counters the reaction to this force. The beams can be formed as extrusions. The joint only requires machining for the transverse opening (4) and smoothbore bolt holes (9A, 9B) for a single bolt. The second beam may have a rectangular cross section with relatively thicker corners (2A-2D) and thinner mid-walls (2E-2H).

A container including a first panel with a first edge having a first protrusion with a first contoured profile with at least one projection, a second panel with a second edge having a second protrusion with a second contoured profile with at least one projection, and a spline with a first channel that defines a recess with an interior profile, and a second channel separate from the first channel that defines a recess with an interior profile. The first and second channels receive the first and second protrusions, respectively, such that the first contoured profile is complementary to a portion of the interior profile and the second contoured profile is complementary to a portion of the interior profile. The first and second panel include a mid-section extending from the first and second edges, respectively. The first and second edges have a greater thickness than the thickness of the mid-sections.

A foldable cover plate is configured to be mounted to a tailstock of the movable device to cover or open an opening provided with the tailstock, and includes a plurality of cover assemblies rotationally connected in sequence. each of the plurality of cover assemblies includes a photovoltaic panel and a substrate. the photovoltaic panel of each of the plurality of cover assemblies is arranged on an associated substrate. The photovoltaic panel is configured to absorb light energy and convert the light energy to electrical energy. Any two adjacent cover assemblies of the plurality of cover assemblies are electrically connected to each other; and in a connection direction of the plurality of cover assemblies, a one-end cover assembly of the plurality of cover assemblies is configured to be electrically connected to an energy storage device arranged in the tailstock to charge the energy storage device.

A stabilizer designed to be used in a single shear fastening configuration to secure a composite panel to an adjacent material is disclosed. The front side of the composite panel is flush with the adjacent material and the back of the composite panel is flush with the stabilizer. As a result, the adjacent material and the stabilizer sandwich the composite panel and mimic a double shear configuration. The stabilizer helps to prevent fastening devices (e.g., screws, rivets, nails) from pulling through the composite panel and adds to the mechanical strength of the fastening application.
