MESH LINK CONSTRUCTION George M. Muray, Hudson Heights, N. J assignor to Daniel Smilo and Sons, Inc., New York,
Application April 12, 1946, Serial No. 661,584
1 This invention relates to new and useful improvements in a mesh link bracelet or flexible plate.
More specifically, the present invention proposes the construction of a flexible wall or plate of the basket-weave type having a plurality of interconnected elements each rigid in itself but so connected that the wall can bend freely and will therefore be adapted for use in the manufacture of such articles as bracelets, pocketbooks, belts and the like.
A further object is to provide a'plate as aforesaid in which each of the elements is formed of a flat sheet of metal bent into shape to provide alternate channels, each channel being opposite a space and adjacent channels being inverted, each of the channels having a flat bottom, one flat leg at right angles thereto, and a tubular leg.
Another object is to provide a'plate as aforesaid in which the tubular legs are semi-cylindrical in cross section.
A further object is to provide a plate as aforesaid in which the tubular legs each have a flat exterior face.
For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.
In the accompanying drawing forming a material part of this disclosure:
Fig. l is a plan view of one type of metal blank from which the elements of the plate of the present invention are formed.
Fig. 2 is a perspective view of a partially formed element.
Fig. 3 is a perspective view of a partially formed plate.
Fig. 4 is a plan view of a portion of a plate.
Fig. 5 is a greatly magnified end view illustrating the assembly of the parts of the device.
Fig. 6 is a side view diagrammatically illustrating another embodiment of the invention.
Fig. 7 is a plan view of a modified form ofblank.
Fig. -8 is a view similar to Fig. '7 showing a blank having a reinforced rib in the center strip thereof.
Fig. 9 is a view in perspective of a fragment of a mesh part showing a panel embossed therein.
Fig. 10 is a section on the line Ill-I0 of Fig. 9.
The blank I 0, shown in Fig. 1 is preferably stamped from a fiat sheet of a suitable metal. It has a-central connecting rib II and tabs I2 extending from opposite sides thereof in alter- 1 Claim. (01. 59-80) nating fashion so that each tab is in line with a space at the opposite side of the rib. The blank can be as long as desired. It is shown relatively small, having three tabs at one side and four at the other.
The blank is then bent along the dotted lines a providing a backbone I3 or center strip having alternate tongues I l and grooves I5, along each of its sides, the tongues being formed of portions of the tabs I2 and the grooves being formed by the spaces between these portions. The tabs are then arranged in two spaced parallel and opposite rows. The ends of the tabs are then bent into a tube l6, each tube having a flat side face II op-- posite to its portion of the backbone, a flat outer face I8 which is part of the tab I2 and an inwardly curled terminal end or face I9.
It will be seen then that each element at any cross section along its length is channel shaped, but as the tabsralternate, so the channels will alternate, one opening upwardly and the next downwardly. Each channel has one straight flat leg formed by portions of the backbone I3..and adjacent tongue I4, a bottom formed by the unbent portion of the tab I2, and another leg formed by the fiat side face II opposite the first mentioned leg, this other leg being generally tubular because of the curved end thereof.
The elements are adapted to be interconnected without the employment of any other parts, and
when so interconnected will present fiat top and,
bottom faces. Furthermore, the plate so formed will be able to flex due to the flexible interfitting of the elements.
The plate is formed by disposing rows of 918-.- ments adjacent each other, that is, substantially in contact, and similarly disposed so that their backbones are all at corresponding sides. These elements so disposed will be interconnected by other similar elements but turned upside down:
with their bottom faces down and their backbones at the right. The top elements are all disposed with their bottom faces up and their backbones at the right.
The manner in which the elements interlock so that they can not become separated is quite unique. The first element is closed, that is, the
bottoms of the channels are pressed down into parallel planes, but the other elements to .-b e
3 connected thereto are left with their channel bottoms diverging as shown in Fig. 2.
The second element is then taken and turned end for end relative to the first element, still maintaining the backbone at the right, however, thus its top channels will be in line with the top spaces of the first element and its bottom channels will be in line with theybottom spaces of the first element. The two elements are then moved together and the channel bottoms of the second element are pressed into parallelism. The
third element is then connected to the second element in the same manner except that it will be disposed similarly to the first element. This will be continued until a plate of the desired length has been formed.
The flexible character of the plate is independent of the thickness of the material used and in the finished plate, the two opposite surfaces thereof are substantially fully closed (solid) except for the cracks between adjacent portions. The curls permit positive proportional link long-theoritrol which is important as for example in the construction of a bracelet. Also there is positive link proportional overall thickness control. metal employed in the present construction may be thin. Nevertheless, the construction plate may be of any desired thickness.
The'outside surfaces of the plate are independent of the inside construction. That is, it may be made concave, convex,.sharp, square and so on. The units may be decorated with holes if desired, and each could .be made with longer and shorter tube-like effect without impairing the automatic locking characteristics. The units lock themselves against opening. Both sides of the plate may be made to look alike or they may be made to look difierent because of the positive location of the links.
In Fig. 4 the tubular legs which have'portions visible from the top are marked with a large A for clarity.
The constructionin Fig.5 difiers from the con ing the units of the first embodiment at thebot tom and the units of the second embodiment at the top. Thus the surface of the bottom is flat withsharp corners of adjacent parts of adjacent units, whereas the top surface has rounde'dco'r-- ners of adjacent parts of adjacent units. plateis more flexible in one direction than inanother and ofiers the advantage that either may.
be turned up. No description. of this plate is deemed necessary, but for easier closing the tubular legs may be bevelled and the parts of the top unit will be indicated bynumerals used for cor-. responding parts of the embodiment of Figs. 1-4
but with the letter a suffixed, and the same ap-. plied to the bottom units but with the sufiix b.
In the form of the invention shown in .Figs. 7". and 8, the center strip is flanked by alter-" nately staggered tabs 26 spaced as at 27 and arranged to be folded on the dotted lines 28. The ends of the tabs 26 are rolled or formed in 'semi-' cylindrical tubular shape in accordance with the forms of the inventionabove described. The op This 4 posite side edges of the tabs may be cut out as at 29 for easing the assembly of desired plate, or they may be provided with rectangular or other ornamental shaped openings as at 30 in Fig. 8. As shown in Figs. 9 and 10, the tabs may be embossed as at 3| for strengthening and ornamenting the blank. In all or any of the forms of the invention, the center strip 25-may 'be embossed to provide a reinforcing rib as at 32, and the end tabs may be formed to provide end ears 33 through the medium of which the ends of the units may be closed so that the interior construction may be concealed and the edges of the device given a finished-closed appearance.
It is evident therefore, that I have provided a ring bracelet or flexible plate in which control of the length of the ring may be governed by the amount of curl, which also controls the thickness of the device. The thickness of the material is of no consequence as the material lends itself to varied formation if used in jewelry or allied lines.
The outside surface shape may be independentoff the inside surface shape and the parts maybe made in one or more colors and reinforced by a bead so that the ring construction can be used in any kind of a chain or'bracelet or ring "or ornament with the side edges closed to conceal the construction if desired. Also the individual rings While I have illustrated and'described the preferred embodiments of my invention, it is tobe understood that I do not limit myself'to the "precise constructions herein disclosed and the right is reserved to'all changes and modifications comingwithin the scope of the invention as defined in the appended claim.
Having thus described my invention. what'I' claim as new, and desire to secure by United States Letters Patent "is:
A mesh link construction, comprising aser'ie s,
of link members, each member having a long-ithe arms being of equalwidths, the arms on one side of the spline being staggered with reference to the arms on the opposite side thereof, the arms being disposed in parallel relation at approxi mately right angles to the spline, the outer ends of the arms being formed with tubular flanges; said tubular flanges being disposed in a common:
longitudinal splane, each link member being a substantial duplicate of every other link memberl-s the link members being arranged in matching pairs, with the tubular flanges of the arms ofbne;
link member being disposed between the arms 'of the opposing link member, in overlapping relation by the bodies of said arms.
