摘要:
A vehicle primarily a mass transit vehicle is formed primarily of composite materials which define a roof section and a floor section of two fiber reinforced sheets connected by an integral core and two rigid side wall sections each formed from welded steel or optionally bolted aluminum defining a series of window openings in a row along the side wall section in a ladder shape. Releasable joints of adhesive are provided between the metal rails and the edges of the composite panels where a web of the panel and the web of the rail extend across the panel at an angle to the first and second surfaces different from 90 degrees so that the web of the panel meets the flange of the panel at an angle greater than 90 degrees.

A hydroformed dovetail joint and method of joining tubular members includes a first hydroformed tubular member having a depression therein and a second hydroformed tubular member having an end. The end of the second hydroformed tubular member is disposed over the depression of the first hydroformed tubular member to join the first hydroformed tubular member and the second hydroformed tubular member together to form a dovetail joint between the first hydroformed tubular member and the second hydroformed tubular member.
摘要:
The present invention relates to new and unique designs that improve and enhance the section properties of load bearing structural members, which have particular, but not exclusive, application in connection with aluminum extrusions for use in screened pool, patio and porch enclosures. The invention utilizes one or more reinforcing inserts or slats which attach to a structural member such as a hollow extruded beam to increase the effective wall thickness of the beam in the area where the slat is applied.

摘要:
A wallboard fastening member and methods of using the same which is adapted to be positioned as a wall stud or joist between existing studs or joists present in a walls and ceilings of residential, commercial and industrial structures. The wallboard fastening member in accordance with the present invention is intended to be used where opposing ends of a piece of wallboard, such as gypsum drywall wallboard, are not aligned with an existing stud or joist to avoid the necessity of fitting up or cutting the wallboard and thus creating undesirable scrap. The preferred embodiment of a wallboard fastening member is a generally elongated member and preferably includes a stepped configuration on one side to permit the wallboard fastening member to fasten adjacent pieces of wallboard having different sizes by using the side having a stepped configuration or to fasten adjacent pieces of wallboard of the same size by using the flat side. In addition, if desired, wallboard fastening member can include score lines or perforations to permit the length of wallboard fastening member to be easily and quickly adjusted.

A system comprising: a fastener and a housing (70), the fastener including a rivet portion having a first head (304) and a shaft (302) extending therefrom, a spring cup (210) received upon the shaft having a top portion (211) adjacent the head (304) and a plurality of spring fingers (212) extending from the top (211) and a hollow collar (214) having a first portion (216) received within the spring cup (210) and a second portion (218) extending beyond the fingers (212), an end portion (308) of the shaft opposite the head (304) being malleable and formable into a rivet head (308') to mate with the housing.
摘要:
A support bracket and track assembly for the support of sectional overhead doors. The assembly comprises a track (110, 112, 114) for supporting the overhead door sections and a horizontal support bracket (80) for supporting the track (110, 112, 114). The assembly further comprises a flag bracket (140) for mounting the track (110, 112, 114) and the support bracket (80) to a structural support, and a tab (90, 120, 130) for attaching the track (110, 112, 114) to the support bracket (80) and the flag bracket (140). A related fastening system for use with overhead sectional door components comprises first (80, 140) and second (112, 114) components, a tab (90) extending from the first component (80, 140) for engaging the second component (112, 114), and a tab slot (120, 130) in the second component for receiving the tab (90) of the first component (80, 140).
摘要:
A coupling mechanism and method which allows for removably securing a chair or sofa back to a chair or sofa base. The coupling mechanism comprises a mounting bracket which attaches to the base of a piece of seating furniture and an engaging back bracket which attaches to the back of seating furniture. The back bracket has a pair of pins which are cooperable with a pair of slots located on the mounting bracket.

An adjustable connection link is provided between the dobby and the first crank lever of the control rods of each loom heddle frame. The connection link consists of two tubular bars of hollow aluminum alloy section pieces, preferably of rectangular cross-section. There is at least one internal rib that is perpendicular to the major sides of the rectangle. The section pieces, moreover, are cut away along opposing sides at their adjacent ends in order to expose the corresponding parts of their internal ribs. These are kept pressed, one against the other, in an adjustable position by a bolt. The bolt is threaded into one end of the section piece and passes through a slotted hole in the corresponding end of the other section piece.
摘要:
In a shaft connecting structure, particularly suitable for fragile or brittle shafts of ceramic materials, used in high temperature environments such as conveyors in sintering furnaces, two shafts are connected in end-to-end driving relationship. Each shaft has one or more axial sector-sectional projections and sector-sectional grooves alternately formed at its end. The sector-sectional projections of each shaft enter the sector-sectional grooves of the other shaft, and the assembly of projections and grooves is clearance-fit in a cylindrical opening of a body which may be carried by the shafts or fixed to another structure.
