L, I INVENTOR. 5 JAMES 1'.- muss:
ATTORN EYS United States Patent 3,007,558 EXTRUDED STRUCTURALMEMBER James T. Miller, Reed City, Mich., assignor to Miller Industries, Inc., Reed City, Mich., a corporation of Michigan Filed July 21, 1958, Ser. No. 749,967 4 Claims. (Cl. 189-34) This invention relates to structural members in general, and more particularly to their construction.
Structural members are known in. numerous shapes, sizes, and forms as adapted to suit the requirements of a particular structure. However, there are certain structural shapes that are more commonly known than others and which have come to be known as distinct in themselvm. These include the tubular form, the channel section, and the I-beam, to mention a few.
'It is an object of this invention to disclosea new and different structural member which is considered to have such application as will cause it to become known of itself. This form of structural member includes the advantages of several of the difiierent commonly known structural forms. v
The structural member of this invention is preferably formed from lightweight metals by the extrusion process. Accordingly, it is simple to make and is light in weight. This makes it less expensive and easier to use.
The structural member of this invention is preferably made in long lengths and of a material which can be readily cut. This enables a manufacturer to run olf standardized stock lengths of the structural member and permits the fabricator to cut the standard lengths to more exact size at the site of use. t
The structural member is tubular in shape which of itself assures considerable strength and rigidity. An open side face is provided and is defined by partial wall flangm to more fully maintain the basic rectangular cross sec- 3' tion of the structural member. Inner side Wall flanges are provided to divide the box sectioned form of the structural member into different structural forms, for added strength and rigidity, and to supplant-any deficiency in having an open side face. These same flanges include means of cooperative engagement with another structural member. Such other structural member has parts received within the open face of the form described and which form semi-closed tubular sections with the flange and partial walls.
One particular use for the structural member of this invention is in the framing of a curtain wall for a building. Such a use is described in my copending patent application Serial Number 710,763, filed January 23, 1958, and titled Frame and Curtain Wall Construction.
In the dravw'ngs:
FIG. 1 shows a perspective view of a length of the extruded structural member of this invention.
FIG. 2 is an enlarged cross sectional view of the structural member of this invention.
FIG. 3 is a smaller cross sectional view of the structural member having another structural member shown in phantom, as disposed for engagement therewith.
The structural member 10 is formed from a lightweight metal, such as aluminum. The structural member is preferably formed by the extrusion process.
The structural member 10 includes a back Wall side 12, side walls 14 and 16, and partial walls '18 and 20 which define the open front face thereof. The partial walls 18 and 20 are spaced to provide the front face opening 22.
The basic cross sectional shape of the structural member is tubular in form; having front, back and side walls, as mentioned. The tubular form is rectangular, though 3,007,558 Patented Nov. 7, 1961 ice 2 it may be square. In any event it is preferably of a semi-closed box section form. 7
Side wall flanges 24 and 26 extend inwardly from the side wall parts 14 and 16. These flanges are aligned with each other, extendthe full length of the structural member, and are disposed in parallel spaced relation to the partial front walls 18 and Z0, and just rearwardly thereof. The side wall flanges 24 and 26, while extended towards each other, are preferably not engaged together. The close proximity of their terminal ends however, does provide the structural member 10 with an internal semi-closed area 28 which is bounded by the back wall 12, side walls 14 and 16, and the side wall flanges 24 and 26. The side wall flanges also form internal channel section areas 30 and 32 with the partial walls 18 and 20.
Transversely disposed rib flanges 34 and 36 are formed at the terminal ends of the side wall flanges 24 and 26. These rib flanges extend towards the opening .22 and normal to the partial walls 18 and 20 which define such opening.
Detent ribs 38 and 40 are formed on the outer side faces of the rib flanges 34 and 36. Such detent ribs face the side walls 14 and 16, respectively.
The ends of the flanges 24 and 26, with the rib flanges 34 and 36, and the detent ribs 38 and 40, are exposed through the. side wall opening 22. The rib flanges and their detent ribs form a partial closure wall for the channel section areas 30 and 32.
The plane of the detent ribs 38 and 40 is spaced sufl'iciently from the plane of the terminal ends of partial walls 18 and 20 to permit the engagement of parts of another structural member therewith through the side wall opening 22.
A suitable other structural member 50 is shown in phantom outline, by FIG. 3, as disposed for cooperativeengagement with the structural member lll. The structural member 50 includes extended arms 52 and 54 which are received through the side face opening 22, and between the terminal ends of partial walls 18 and 20 and the detent ribs 38 and 40. The ends of the arms 52 and 54 of the other structural member 50 are formed for intercooperative snap-on engagement with the detent ribs 38 and 40, and have their terminal ends abutting the side wall flanges 24 and 26.
It will be noted that the extended arms 52 and 54 of the structural member 50 will serve to further close the channel areas 30 and 32 of my structural member 10, thereby providing a still more solid structural member in use.
It will also be noted that the side wall flanges 24 and 26, extending as they do out from the side walls 14 and 16, have a certain amount of resilience which permits some relative flexing of the detent ribs 38 and 40 for greater ease in the snap-on engagement thereof with other members. This aspect of the structure dis closed may be taken advantage of, or may be repressed, by having the side wall flanges formed thicker or less thick as desired.
The structural member 10 thus includes an outer semitubular shape provided by external walls 12, 14, 16, 18 and 20. It has an internal semi-closed tubular, or box sectioned area, 2 8 as well as the semi-closed channel areas 30 and 32. The latter are near the open side face of the structural member and strengthen the sides of the opening 22 as well as the whole structure. The side wall flanges 24 and 26 serve to partially form the semi-closed areas 28, 30 and 32, and may be laterally flexible for purposes of greater ease of snap-on engagement with other structural members.
The structural member of this invention has the flanges 24 and 26, rib flanges 34 and 36, and detent ribs 38 and 3 40, extended throughout the length thereof. Accordingly a short or an elongated length of the structural member may be readily obtained by cutting such member to the size required.
