FLEXIBLE OR ROLLING METALLIC SHUTTER..
Specification of Letters Patent.
Patented June 6, 1911.
Application filed March 26, 1909. Serial No. 485,937.
To all whom it may concern:
Be it known that I, WILLIAM M. BRUNST, a citizen of the United States, residing at Columbus in the county of Franklin and State of hi0, have invented a certain new and useful Improvement in Flexible or Rolling Metallic-Shutters, of which the following is a specification.
The object of thisinvention is to provide an improved slat for the construction of metallic rolling shutters or curtains.
The invention is embodied in the construction herein shown and described and particularly pointed out in the appended claims.
In the accompanyin drawing Figure 1 is a vertical section and perspective of fractions of three slats according to my inven tion joined as when in an unrolled shutter or curtain. Fig. 2 is a section showing two slats flexed at the joint. Fig. 3 .is a diagrammatic section of the joint as .shown in Figs. 1 and 2 to better illustrate the principle of the preferred construction of joint. Fig. 4 is a section of a modification.
Referring more particularly to Fig. 3 the slat body*5 is bent away at its lower margin or portion to form a wall-or shoulder 6 that, generally speaking; stands at an acute angle to the plane or t e body of the slat, and from the outer edge of said wall 6 said edge or margin is bent upward and in'clinedly in a straight plane toward the side of the slat to form a wall 7 and this latter wall is finally bent at its extreme edge to form a terminal hinging roll 8, But assuming that the point a is the axis of motion of the parts described I prefer that wall (3 be curved from its outer edge or angle at b to a point 0 on an arc concentric with said axis, said point 0 being about midway the wall and from that point be tangent to said are. The joint member at the upper edge of the slat is formed in substantially the same way except that the wall 6- is made at an obtuse angle to the body of the slat and the roll 8 terminates in a rather deep straight edge instead of a curved one in cross section. When the curtain is normally hanging the bearing between adjoinresting on the upper edge of the lower hing ing member of slat ne'irt above but the arc of this hearing between the hinging mem'-.
bers is in. my construction comparatively small. Because the inclined wall 7 and its parallel companion wall are substantially tangential to this are the wall 7 moves. j
away from its said companion wall upon the fiexion of contiguous slats as depicted in Fig. 2. As the jointing member at the lower edge of one slat is to be slid into the complementa jointing member at the upper edge 0 another slat the latter is, of course, made of slightly lar 'er dimensions to rmit this; but these'dirnensions arepre erably such that the 'ointing members lie parallel to and in sli ing contact with each other so that when the shutter or cur-.
permit of the making the walls 6, 6 more nearly horizontal. With this construction it will be noted'that the axis of flexion of the-joint members and the point or line of suspension between eachpair of slats is thrown nearathe'plane of the bodies or face of the shutter; hence the latter will hang more nearly in a true vertical plane and therefore travel with less friction in the up operation. The said curved walls also i vertical channels usually provided for metallic shutters or curtalns than where the said axis or line is greatly offset from the plane of the slat bodies.
In Fig. 4, I have illustrated SL mOdIfiCMHO II of the construction in which the idea of putting the axis of flexion and line ofsuspension near the plane of the slat bodies 1s employed, but in which the contact between the parts of the joint members is not maintained upon flexion. 4) the parts of the joint will usually in contact so long as the curtain is n upright position in a proper channel orguido.
Viewed in a general way the cross sect on of the joint is in that form of atnangle with.
In this construction. (Fig.
the axis of movement of one of its members near one of the angles.
W'hat I claim is:
1; In a'flexible or rolling shutter or ourtain, slats or sections forming the same having their edges bent to fo m complementary joint members, the walls of which extend first oil from the body of the slat and then toward the plane of the body of the slat, and hinging members at the terminals of said last named walls, said last named walls being tangential to the are of the hearing between said hinging members when the curtain is normallyhanging. A
2. In a flexible or rolling shutter or ourtain, slats or sections forming the same having their edges bent to form complementary joint members, the walls of which extend first ofi from the body of the slat and then toward the plane of the body of the slat, and hinging'members at the terminals of said last named walls, said walls being parallel to each other to nearly their terminal edges and tangential to the arc of the bearing between said hinging members when the curtain is normally hanging.
I 3. In a. flexibleor rolling shutter or ourtain, slats or sections forming the samehaving theiredge's bent to form complementary joint members,,the walls of which extend first off-from the body of the slat and then toward theplane of the body of the slat, and
hinging members at the terminals of said last named walls, said first named walls being parallel to each otherand at their outer portions formed on arcs concentric with the axis of-the hinging members but on greater radii than those on which the said hinging members are formed.
4. In a flexible or rolling shutter or ourtain, slats or sections forming the same having their edges bent to form complementary joint-members, the walls of which extend first off from thebody of the slat and then toward the plane of the body of the slat, and hinging members at the terminals of said last named walls, said first named walls being-parallel to each other and at their outer portions formed on: arcs concentric with the'axis of the hinging members and at their inner portions qrmed tangent to said are and the second-"named walls being tangent to the bearing of the'hinging memb is when the curtain is in normal hanging -p sition.
5. In a flexible or rolling shutter or ourtain, slats or sections forming the same hav- -\ing their edge portions bent to form complementary joint members that are, in cross section and generally, of the form of a triangle with hinging members at the terminals I of the joint forming portions.
v6. In a flexibleor'rolling shutter, slats 'or sections having their edges bent to form walls that'extend first from and then toward the body of the slat, said bent edges terminating in hooks constituting connecting and suspending members, the walls that extend I toward the body of the slat being tangential to the bearihg arcs of the hooks.
