COLLAPSIBLE UMBRELLA Application led August 9, 1929. Serial No. 384,569.

Our invention relates to a new and improved collapsible umbrella.

One of the objects of our invention 1s to provide an umbrella of the collapslble type, and which is preferably made of telescoplc members so that the umbrella can be extended to form a device of ordinary size, and 1t can also be readily collapsed into compact form for convenience in storage, shipment or use.-

Another object of our invention is to provide an umbrella whose main parts are eX- tensible, and to provide simple and efficient` latch devices for holding the principal parts of the device in extended position.

Another object of our invention is to provide a device of this type whereby the latch devices previously mentioned can be conveniently released so as to permitthe device to be collapsed.

Another object of our invention is to produce a device of simple and sturdy construction.

Other objects of our invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof, it being understood that the above general statement of the objects of our invention is intende-d merely to generally explain the same and not to limit it in any manner.

Fig. 9 is a front elevation of an intermediate rib section.

Fig. 10 is a sectional view on the line 10-10 of Fig. 9.

Fig. 11 is a front elevation showing an outer or bottom rib section and its locking device.

The umbrella has the usual holding knob K, and it is provided with a central rod or stick comprising an outer or lower telescopic member 1, an intermediate telescopic member 2, and a top telescopic or outer telescopic member 3. While we have shown the essential parts of the device formed in three ad lustable or telescopic sections, it is to be un erstood that we are not limited to any particular number of adjustable sections, and that the telescopic relation between the parts merely illustrates one form of the invention.

The outer rod member 1 is connected to the knob K in any suitable manner and it is provided with a spring latch 4 having the shape shown in Fig. 3, the inner end of said spring latch 4 being held within the hollow innerl member 1, by means of a plug member 5. The head of the spring latch 4 has the inclined contour shown in Fig. 3 and it can project through a slot in the wall of the inner mem- Said head can also project through a corresponding slot in the intermediate rod member 2 when said slots of members 1 and 2 register, said position being shown in Fig. 3. Hence, when the intermediate sleeve or rod member 2 is slid to its outer or extended position, which is shown in Fig. 3, the head of the spring'latch 4 automatically moves to the position shown in Fig. 3, so as to lock the intermediate member 2 in fixed position with respect to the innermember 1.

Likewise, and as shown in Fig. 3, the inner head of the outer member 1 is slightly enlarged, and the intermediate member 2 is correspondingly shaped, in order to limit the outer sliding movement of the intermediate member 2 on the outer member 1.

The' intermediate member 2 is provided 9 with a latch 6, clearly shown in Figs. 3 and 4. Said latch 6 has a laterally tapered or cam-like4 end, as shown in Fig. 4, and it is connected to a resilient ring or member 7 so that said ring or member 7 urges the outer latch 6 into the position shown in Fig. 3, which position it projects through slots 1n the members 2 and 3, in order to lhold. said members 2 and 3 against relative movement.

The outer end of the sleeve-like intermediate member 2 is also enlarged, as shown 1n Fig. 3, and the outer'sleeve-like member 3 1s correspondingly shaped, sol as to limit the outer locking recess in the outer member 3 operates force the same inwardly,

upon the inclined surface of the latch 6 to until said latch 6 releases the member 3, so that said inner member 3 may be pushed-outwardly towards the knob K. i

The links 8 which are connected to the ribs of the umbrella have pivotal connections 11 to a slidable ring or runner moved to an inner 4position and toan outer position as shown in Figs. 1 and 2. As shown in Fig. 1, the slidable runner .10, nts within the hollow member 35 which 1s suitably connected tothe knob K, when the devicel is completely collapsed. T he said runner 10 is provided with an ordinary spring latch 61 which engages a suitable recess 1n the outer section 3, when the device is extended, this being clearly'shown in Fig. 2.

' When the device is to be collapsed, the runner 10 is released from the position shown 1n Fig. 2 and said runner 10 is then moved in-v wardly in order to move the ribs inwardly. The outer section 3is turned to release it from the intermediate section 2, and the inner section 3 is then slid outwardly or towards the knob K. The outer end of the member 3 then passes between the runner 10 and the intermediate section 2, so that the head of the spring latch 4 is forced laterally until it releases the intermediate section or member 2.

Hence, thecollapsible rod can be extended from the position shown in Fig. 1 to the position shown in Fig. 3 by pulling outwardly upon and also turning the knob K, while holding the head H, and it can be collapsed from the extended position shown in Fig. 3 by first turning the knob K and then pushing inwardly upon said knob, while holding the head H.

The sleeve 35 is provided with a ianged sleeve 21 connected thereto, and the heads 20 of the ribs of the device are normally retained by the ange of the member 21, while the collapsible rod is being extended from the collapsed position shown in Fig. 1 to the extendposition shown in Fig. 3. The sleeve 21 10 which can be -is turnable on sleeve 35, any suitable meansv being used to prevent their separation permitting sleeve 21 to freely turn. when knob K is turned, the sleeve 21 can remain stationary, so that the heads of the ribs also remain stationary, and parallel to the central axis ofv thedevice. A band 60 may be employed to keep the ribs in the position 'shown in Fig. 1.

In this embodiment, each ofthe ribs of the umbrella is -illustrated as comprising three telescopic sections 'although as before menstioned, we do not wish to be limited to any particular number of sections, orto the specific shape or shapes shown for purposes of illustration.

As shown in Fig.3, the inner rod section 3 is provided with a ring 15 to which the inner rib sections 9 are pivotally mounted at 36. Coil springs 16 are provided and these urge the ribs to the extended position shown in Fig. 2. The springs 16 may be strong enough to move the ribs to their extended or operative position or the springs may be somewhat weaker, so as to merely assist the action of the runner 10 andthe links 8 in moving the ribs to their operative position. In any event, the springs 16 are sufficiently strong so that when the heads 20 of the ribs are released,A after the central rod has been extended to the position shown in Fig. 3, the ribs initially turn until they assume an 'angle of about twenty (20) degrees to the central axis y of the device. The headsof the ribs can be held in the position shown in Fig. 3, by means of any suitable device, such as a tape, strap or the like. In the position shown in Fig. 3, the ribs have been substantially fully extended, and it is-merely necessary to swing the ribs about their pivots 36, to cause said ribs to assume the open position shown in Fig. 2.

The inner rib section 9 is longitudinally slotted and it is provided with a collar 18 riveted or otherwise secured to its outer end. Each intermediate rib section 12 is also preferably longitudinally slotted-and it is provided with a head portion 17 to which one of the links 8 is pivotally connected. When the ribs are extended to the position shown in Fig. 3, the head portions 17 of the intermediate rib sections 12 abut the collars 18, so as to prevent any further extension of the ribs. After the ribs have been initially inclined by the springs 16 as previously mentioned, it is merely necessary to push upwardly upon the runner 10. Since the links 8 are now inclined to the ribs, the thrust exerted upon the links 8 causes them to swing the ribs laterally to the position shown in Fig. 2. If the ribs were not first inclined, the actuation of the runner 10 would merely slide the intermediate rib sections 12 upwardly upon the outer rib sections 9. However, the inclined positions of the links 8 and of the ribs causes the links to swing the ribs, without producing any relal-Ience,

y mosaic tive slidin movement between the rib tions 12 an 9.

Each outer rib section 14 is provided with a head 20. In describing the rib section 14 as the outer rib section, reference is made of course to the positions of the parts when they are in the open condition shown 1n 'Ihre outer rib sections 14 are provided with spring latches 22 which roject through slots in the walls thereof. ence, when the knob K is pulled outwardly, said spring latches 22 engage the lips 12'* which are integral with the walls of the intermediate members 12, so as to hold the parts of the ribs in the extended position shown in Fi 3. Each intermediate section 12 is provided with additional lips 24 which engages the inwardly bent flange 23 located at the inner end of the associated rib section 14, so as to limit the sliding movement between sections 14 and12.

When the device is collapsed by pushing the knob K towards head H, the collars 18 which are connected to thev outer ends ot the rib sections 9, engage the inclined projecting faces of the latches 22, so that said latches 22 release the intermediate rib sections 12.

It is obvious that the operation of the device is extremely simple because in order to open the umbrella, it is merely necessary to pull the knob K into the position shown in F ig. 3, whereupon the springs 16 are effective to swing theribs to their operative position, or to an initial inclined position, or else said ribs can be disengaged from the position indicated in Fig. 3 by hand, and the collar 10 can then be manipulated to open the umbrella.

In order to collapse the device, it is merely necessary to bring the parts into the position shown in Fig. 3, and to then turn the knob K, and to then push the same inwardly.

As shown in Fig. 1, the fabric cover F of the umbrella is connected to the ribs and to the head H in any suitable manner.

In order to present a neat appearance, the umbrella can also be provided with a case C made of any suitable fabric or material and this can be rovided with an outer sleeve 30, which can t snugly upon the head H.

It will be noted, as shown in Fig. 3, that a pair of slidable sections ofthe central rod are provided with latch means to hold them in extended position.l It will also be noted that a succeeding rod section, namely, the section 3, is provided which operates as a control means to move said latch means into inoperative -position when the device is collapsed. The rib sections are similarly constructed.

I/Vhile we have shown a complete umbrella embodying various improvements, it is clear that one or more of these improvements could be incorporated into umbrellas whose construction would be different from that of the `nrality of telescopic sections,

with an inner portion tudinal slot through preferred embodiment shown herein, so that these subcombinations could be utilized independently of the main combinations described herein.

In eneral, while we have shown a' referre embodiment of our invention, it is. clear that numerous changes and omissions could be made without departing from its spirit.
