Application June 8, 1942, Serial No. 446,166
This invention relates to pocketbook frames and in particular to one made of Wood and has incorporated therein novel means for joining the parts of the frame to provide a whole.
A particular object of the invention is to provide a frame made of wood or plastic material, preferably wood, which can be readily manufactured at minimum cost, quickly assembled and one which has novel hinging features and holding means that prevent the accidental opening of the pocketbook or purse. It is understood that while the device is referred to as a frame for pocketbooks, the invention as illustrated in a pocketbook frame may be readily applied to other containers or holders that employ a closure frame for one edge thereof.
A further and equally important object of my invention is the provision of novel hinge means, the construction of which is so carried out that fastening means for holding the opposed portions of the frame in close contact may be dis pensed with if desired. The hinge hub is so constructed that a resistance to the falling open of the frame parts to open up the bag or pocketbook is provided, which operates without any attention on the part of the carrier f the bag and also constitutes an inherent part of the frame structure. In this way, metal parts such as hinges, pivot pins, clasps and other accessories of hardware nature are eliminated in the manufacture of the bag.
A still further object of the invention is to provide a frame structure that conceals the separating parts of the frame so that without knowledge it is difficult to open the frame parts quickly and hence the contents of the bag are to some extent protected without actually looking the frame parts together.
With these and other objects in view, the invention comprises certain constructions hereinafter described and then particularly pointed out in the claims and a preferred embodiment of my invention is illustrated in the accompanying drawing, in which:
Figure 1 is a view in perspective of a Wood frame constructed in accordance with my invention, the parts of the frame being shown opened or separated to illustrate the hinge construction,
Figure 2 is an enlarged view of one end of the frame, the parts being in closed position, said view illustrating the shape of the hubs and rider portions of the hinge structures,
Figure 3 is a view similar to Figure 2 showing the hinged frame parts opened to an angle of substantially ninety degrees,
Figure 4 is a view of one of the hinge hubs showing diagrammatically the construction thereof,
Figure 5 is a view similar to Figure 4 showing a modified form of the hinge structure,
Figure 6 is a view in perspective of a modified form of frame construction in which one of the frame parts folds Within the other or outer frame part to make the bag diflicult to open to one not familiar With its operation, and
Figure '7 is an enlarged section on the lin 1--! of Figure 6 showing a means of frictionally holding the parts of the frame together so that no other fastening means is necessary.
Referring to the drawing in detail, 10 indicates the frame of a pocketbook or like receptacle, which is not shown, but whose upper end is arranged to be closed by the contact of two frame members hinged for swinging movement to facilitate access to the bag interior. The frame consists of two identical parts as illustrated in Figure 1 so that in actual manufacture only one pattern or template need be used from which to make any number of the frame pieces ll, one of which is reversed to complete an entire frame and each piece consists of the elongated top portion l2 terminating in depending sides I3. Each of the side portions I3 at their extremities are cut to provide an angularly disposed rider M, a hinge hub cavity l 5 and cylindroid hub 16. The parts of the frame are hinged together by passing through the hubs l6 thereof, the pivot pins.
I! which may be made of wood, plastic or other suitable material and I may preferably employ hinge pins of fibrous material or plastic that are bendable or flexible so that they will permit yieldingly, a small movement of the hubs with respect to each other as will be later referred to. The under side of each frame piece II is grooved as at H! to provide a seat into which is glued or otherwise fastened the edge of the material making up the body or receptacle portion of the pocketbook. This construction is so well known in the art that no illustration appears necessary.
The hubs I6 at the ends of the side portions are alike and a description of one will sufiice. In Figure 4 is shown the end of the hub I-B, which is substantially elliptical in cross section or end view and forms a cylindroid hub, whose extended surface I 9, formed on a radius 20 from a point off the center of the hub or pivot pin l1, acts as a lifting surface or wedgin-g means to offer a frictional resistance to the passage of the angularly disposed rider l4 thereover. The under surface of the rider l4 as'it moves over the surface of the cylindroid hub will flex the pivot pin with the result that the frame parts can be brought together to close the bag and will not fall apart to open the bag. This reduces the danger of the purse or handbag from accidentally opening even should the frame holder catch be in open position. The frame catch 22 is made from one piece of wood or plastic and is shaped to provide a saddle portion 23 and integral arm 24 which is pivoted to the frame piece as at 25 so that the catch can be opened or closed as desired.
The radius 25 of Figure 4 has as its center the pivot pin l1 and when the frame parts I I are swung to open position, the rider surfaces [4 leave the surface of the hub as defined by the radius 20 and the frame parts swing freely to full open position. The extent of the frictional resistance is controlled by the angle A, which defines the relative angular positions of the radii centers 20 and 26, with respect to the vertical. In Figure 2, the angle is the same as in Figure 4 degrees). Figure 3 shows the riders free of the hubs when the frame parts are opened to ninety degrees, but Figure 2 shows the frame parts in frictionally held closed contact.
In Figure 5, the angle A is 60 degrees with the vertical and where the peripheral surfaces (of the radii 28 and 29) meet, a depression 30 in the hub is formed longitudinally of the upper surface thereof into which the nose end 3| of the angularly disposed rider surface 32 may rest to maintain the frames in contact without any latching means. It is evident that the variation of the angle A will position the axis of the cylindroid as desired to create the frictional resistance to movement of the frame parts for a greater or lesser degree depending upon the requirements.
In Figure 6 the frame parts are of different construction, the outer frame piece 35 comprising a top portion and legs or sides 31 which terminate in the rounded ends 38 carrying pivot pins 39 on which are journalled the plain or cylindroid hubs 40 that are similar to the ones employed in the frame pieces of Figure 1. The hubs 40 are the terminals of frame piece 35A, the high portions of the hubs (as described in connection with Figure 4) acting to frictionally engage the rider surfaces 42 formed at the lower ends of the undercut wal143 of frame piece 35. The undercut wall 43 provides a seat for the frame piece 35A so that the latter is concealed except at one side of the frame and is thus rendered difiicult of detection. The frame piece 35A is frictionally held in its closed position within the frame piece 35 by the coaction of the rider surfaces and the cylindroid hub portions.
In the event that plain hubs are employed on v the frame piece 35A, the upper edge of the latter may be beveled as at so that it will frictionally fit under the top part of the frame piece 35 as illustrated in Figure 7. The under sides of both frame pieces 35 and 35A are fluted or grooved as at 5| to provide for attachment of the receptacle forming material of the pocketbook.
My invention is not to be restricted to the precise details of construction shown since Various changes and modifications therein may be made without departing from the scope of the invention or sacrificing the advantages derived from its use.
What I claim is:
In a frame for pocketbooks or the like, matching U-shaped frame pieces having free ends of identical construction, each end presenting a unitary hub section and a contiguous hub cavity, the hub section and the hub cavity each extending substantially half the width of each of said ends, and said cavities and hubs being arranged to interfit when two frame pieces are assembled, said hub sections presenting a cylindroid shape in cross section and said cavities presenting angularly disposed hub engaging nosed edge walls for frictional engagement with the coacting hub to control the relative swinging movement of the frame pieces, yieldable pivot pins for joining the hubs to provide an articulated frame structure, and a depression formed longitudinally in the upper surface of each hub providing a seat for the nosed angular edge wall of the hub cavity whereby the frame pieces are yieldably maintained in closed contact.
