Claims.

This invention relates to fans, and more particularly to foldable fans of the type wherein separate sheets are united to produce the foldable conditions.

An object s to create a simple and inexpensive fan of this kind wherein the separate sheets are slidably interlocked with each other. Attention will be directed to interlocking conditions produced by merely folding and lapping the side margins of adjacent fan sections, so as to effectively unite the several sections, and at the same time limit pivotal movements thereof.

With the foregoing and other objects in View, the invention comprises the specific combination and arrangement of details herein shown and described to illustrate one form of the invention. However, the scope of this patent extends to variations and modifications more broadly described by the terms employed in claims hereunto appended.

Fig. 1 is a front view of a sectional fan embodying features of this invention, with a portion of the middle section broken away to more clearly show an interlocking condition at folded side margins of adjacent fan sections.

Fig. 2 is a section taken on the line 2--2 in Fig. 1.

Fig. 3 is a section on the curved line 33 in Fig. 1.

Fig. 4 is a front view of the fan in a folded condition.

Fig. 5 is a horizontal section on the line 5--5 in Fig. 4.

Fig. 6 is a rear view of the middle section, showing its inturned side margins.

Fig. 7 is a rear view of one of the side sections, with dotted lines showing an inturned side margin to be interlocked with the middle section.

In this form of the invention there is a middle section A pivoted to and slidably interlocked with side sections B and C. The several sections, when interlocked with each other as shown in the drawings, have inturned reinforcing flanges and, therefore, can be made of relatively thin paper, or other weak sheet material. However, in Figures 2, 3 and 5 the thickness of the most desirable sheet material is enlarged to more clearly show the interlocking conditions.

The middle fan section A is formed by a sheet of material having tapering side edges 8, and folded side margins 9 extending inwardly from said side edges 8. The lower ends of the folded side margins 9 may be lapped at a reduced lower portion of the tapering middle section, as shown in Fig. 6.

I will now refer to details of the tapering side sections B and C extending from the middle section A. The section B has a folded inner side margin in arranged within and embraced by one of the folded side margins 9 of the middle section A. The section C at the opposite side of section A is likewise provided with a folded inturned inner side margin l l arranged within and embraced by a folded side margin 9 of said middle section A.

The several folded side margins 9, l0 and II can be conveniently lapped at the lower portion of the fan, as shown most clearly in Fig. 2 to receive a pivot I2 which extends through all of these lapped margins and also through body portions of the main sections A, B and C.

The pivot I2 is conveniently formed by a hollow eyelet, but any other suitable pivot may be employecl.

The inturned side margins embrace each other to limit pivotal movements in opening the fan, while also serving as reinforcements for the sheet material.

When the fan is closed, as shown in Fig. 4, extensions l3 can be grasped and pulled away from each other to open the fan. These extensions l3 project from outer edges of the fan sections B and C.

I claim:

1. A foldable fan comprising separate fan sections pivotally connected together, each of said sections havin a folded side margin lapping and slidably interlocked with one of its companion fan sections to limit relative pivotal movements of said separate fan sections.

2. A foldable fan comprising separate fan sections pivotally connected together, each of said sections having a folded side margin lapping and slidably interlocked with one of its companion fan sections, and each of said folded side margins being arranged within and embraced by the folded side margin of an adjacent fan section, so as to loosely unite the adjacent sides of said separate fan sections.

3. A foldable fan comprising fan sections formed by separate and distinct sheets slidably interlocked with each other, each of said separate sheets having a folded side margin lapping and slidably interlocked with one of its companion fan sections, each of said folded side margins being arranged within and embraced by the folded side margin of an adjacent fan section, so as to loosely unite the adjacent sides of the separate fan sections, and a pivot connecting the lower portions of said fan sections.

4. A foldable fan comprising a middle fan section formed by a sheet of material having tapering sides and folded side margins extending inwardly from said tapering sides, the lower ends of said folded side margins being lapped at a reduced lower portion of said tapering middle section, tapering side sections formed by separate sheets of material extending from said middle section, each of said side sections having a folded inner side margin arranged within and embraced by one of the folded'side margins of said middle fan section, the several folded side margins of said sections being lapped at the lower portion of the fan, and a pivot extending through said lapped margins so as to pivotally connect the separate fan sections.

5. A foldable fan comprising middle and side sections pivotally connected together and having inturned side flanges slidably interlocked with each other to limit the separation of said side sections from said middle section, each of said side sections having an extension at its outer edge to be grasped in separating the side sections.
