Patented May 6, 1952 UNITED STATES PATENT OFFICE 2,595,597 TELEscoPING HANDLE Richard H. Morseth, Everett, Wash.

Application July 5, 1949, Serial No. 103,069

, 3 Claims. Y l

This invention relates to improvements in telescoping handles, rods and the like, and has reference more particularly to a telescopic handle made from metal or plastic tubing and especially designed for use in connection with dip nets, although the invention is not to be conned to articles of that particular kind.

It is the principal object of this invention to provide a handle from cylindrical tubing, comprising parts that are telescopically assembled and wherein novel means is provided for retaining the tubular sections against relative axial rotation when the handle is functionally extended.

It is also an object of the invention to so design the parts as to eliminate binding and incident difficulty in making telescopic adjustment of parts, yet avoiding undesirable looseness of the assembled parts.

It is also an object of the invention to provide novel means for mounting and securing the dip net frame in the handle.

Still further objects of the invention reside in the novel details of construction and Icombination of parts, and mode of use of the device as will hereinafter be fully described.

In -accomplishing the above mentioned and other objects of the invention, I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein:

Fig. l is a perspective view of a dip net, equipped with a telescopic handle embodying the improvements of the present invention therein.

Fig. 2 is an enlarged, longitudinal sectional view of the joint portion of the handle, showing the relationship of tubular sections whenv the handle is extended.

Fig. 3 is a perspective view of the outer end portion of the tubular inner end section of the handle.

Figs. 4 and 5 are enlarged cross-sectional views taken on lines 4 4 and 5 5, respectively, in Fig.2.

Fig. 6 is a sectional detail on line 6--6 in Fig. 7, of the mounting block for the end portions of the dip net frame as applied to the handle.

Fig. 7 is a cross-section on line 'I-'I in Fig. 6.

Referring more in detail to the drawings:

In Fig. 1, I have illustrated the present improvements as embodied in a handle applied to a dip net. The net is designated by numeral I0,

its mounting frame by numeral I I and the handle as attached thereto is designated, in general, by numeral I2.

The handle comprises two tubular sections I3 and I4; the outer section I4 being telescopically assembled about the inner section I3 for its adjustment between extended and telescoped relationship.

It is desirable that there be slight clearance between the telescoped tubular sections in order to avoid binding' that might result from any irregularity in the formation of either part I3 or I4. This slight clearance is best shown at I5 in Fig. 2.

The section I4 comprises a length of tubing of uniform diameter, and it is equipped at its outer end with a knob or enlargement I6 designed to prevent the handle slipping from the hand when held in normal use. The preferred form of knob is one of rubber and it is slipped over and secured to the tube end. However, other forms of knobs or grips might be used. For example, a grip like that applied toa bicycle handle bar would satisfactorily serve the purpose.

At its outer end, that being the end that is telescoped within the tubular section I4, the tube I3 is expanded into hexagonal form, as best shown in Fig. 3. In forming the tube to this outline, as a method of providing it with a plurality of longitudinal ridges of increased diameter, as designated at I'I, shown in Figs. 2 and 4, the exterior diameter of the tube as determined by the measurement across the end of the tube between opposite ridges of the hexagonal portion, is increased to the full inside diameter of the tube I4. This is most clearly shown in Fig. 4, wherein the dash line `circle I9 represents the diameter of the main body of tube I3; and it is therein noted that the corner portions or ridges I'I of the hexagonal end portion extend beyond this circle, and between the ridges the flattened surfaces I8 are substantially tangental to the circle I9. This detail 0f construction, pertaining to the locking of the telescoped parts against rotation when in extended relationship, will presently be fully explained.

At its inner end, the tubular section I4 is slightly constricted as at 25 in Fig. 2, to closely rit the tube I3, and has a band or ring 26 tightened thereabout. Near the constricted end, the tube is formed with an encircling, inwardly pressed bead 2l, giving the tube an inside diameter, at this location, equal to the outside diameter of the container tube I 3. The tube I3 ts closely in tube I4 only at the line of contact with bead 21 and the restricted end 25, and thus has relatively free longitudinal adjustment without loss of rigidity.

Pressed inwardly from the wall of tube I4,

slightly away from the bead 21 in a direction toward the outer end, are six inwardly pressed bosses 30. These are equally spaced apart and extend inwardly to about the same extent as the bead 21. When the handle section I4 is drawn out, as seen in Figs. 1 and 2, the expanded. end portion thereof will be brought into registration with the encircling row of bosses, and the ridge portions of the hexagonal end portion will be disposed between the bosses as shown in Fig. 4, and the tube I4 will thereby be locked against rotation relative to the tube I3. The net may then be manipulated by the hand hold I6 on section I4. The fact that the end portion of the tube I3 is slightly expanded beyond the normal diameter of the tube in giving it the hexagonal form, thereby prevents the section vI4 from being drawn out and detached from tube I3. However, the part I4 may readily be telescoped over the part I 3.

At the outer end of the tube I4, near the knob 20, a bead 50, similar to the inwardly compressed bead 21, is provided. The purposeof the bead 50 is to retain the tube I3 when telescoped within the section I4. This bead frictionally engages the hexagonal end of the tube I3 and releasably .retains the tubes in telescoped relationship when not in use. A slight pulling outward will cause the tube I3 to be released and readily extended for use.

The means now preferred for mounting and securing the net holding frame Il in the handle is illustrated best in Figs. l, 6 and '7, wherein it is shown that the frame .comprises a single length of small-diameter tubing bent to loop form. The end portions I I -I-I of the -tube are brought together and extended in parallel relationship, as in Fig. 6, into holes 35 bored to receive -them in the end wall 40' -of a hollow plug 40 that is liitted in the inner end of tube I3. yA hole 42 is then bored diametrically into tube I3 Yand plug 40, as noted in Fig. '7. Then a screw bolt 44 possessing an enlongated, tapered head 44a is projected through the hole V42, .between portions II'I I' and threaded into the lower wall of the tube, as shown in Fig. 7. Thereby the portions II'-I I' are spread apart `as indicated and securely retained within tube I3, and `also the .plug is secured in the tube.

This form of tubular handle is especially desirable for dip nets. However, it is useful for other articles, and the improvements therein may be applied to tubular telescopic'handles of aluminum, plastic or other materials.

Having thus described ymy invention, what AI 4 claim as new therein and desire to secure by Letters Patent is:

1. A handle of the character described comprising two tubular telescopically assembled sections; the inner of said sections having clearance thereabout within the outer section and being expanded at its inner end into polygonal form to the full inside diameter of the outer section; the outer of said sections being formed with an inwardly pressed bead adapted to be engaged by the end surfaces of the expanded portion of said inner section to limit the extension and there :being at least one boss inwardly formed on the outer section adapted to engage one of the flat surfaces of the polygonal portion to prevent relative rotation of the sections when extended.

2. A handle of the character described comprising two tubular, telescopically assembled sections; Athe inner of said sections having clearance thereabout within the outer section and being expanded at its contained end into ,polygonal form to the full inside diameter of the outer section; the outer of said sections being constricted in diameter at that end that receives the inner sections, to closely fit said inner section, and formed in spaced relation to said constricted end with an inwardly pressed encircling bead adapted to be engaged by the end surfaces of the expanded polygonal portion of the inner section to limit the extension of the handle, and bosses inwardly impressed from the outer section in position to be engaged by the respective iiat surfaces of the polygonal portion of the inner section to prevent relative rotation of the sections when extended.

3. A handle as in claim 2 wherein the outer tubular section is formed with an inwardly impressed bead in that portion opposite its constricted end to frictionally engage with the polygonal portion of the inner section when the sections are fully telescoped.
