Int. Cl. A4sb 25/00 U.S. Cl. 135-44 1 Claim ABSTRACT OF THE DESCLOSURE The invention is concerned with a telescopic pocket umbrella frame having a stick with a handle at its lower end to which a carrying loop is attached. The ends of the loop are secured near to the periphery of the handle.

In pocket umbrellas in which the handle is not curved that is to say mainly in pocket umbrellas for women, the lower surface of the handle is usually equipped with a button which serves as the attachment point for a carrying loop. In those pocket umbrellas in which there is a push button in the lower surface of the handle, for unlocking the umbrella stick, this push button is usually used as the point of attachment for the carrying loop. The button has a transverse drilling in which there is secured a key ring, the carrying loop being attached to the key ring.

A button projecting from the lower surface of the handle has certain disadvantages. In the first place, the button increases the overall length of the umbrella. In pocket umbrellas even a small increase in length, of only a few millimetres, is still an important disadvantage. Furthermore the key ring tends to get tangled with objects in a womans handbag, and when the umbrella is withdrawn from the bag the objects tend to come out with the umbrella. Finally, when the umbrella is being carried by its carrying loop the button is subjected to torques. If the button serves as a securing screw for the handle, then the torques can loosen the button and under certain circumstances unscrew it entirely. To get around this difficulty is has already been proposed to mount the button, which also serves for unlocking the stick parts, rotatabl in the handle. But this requires that the button must be equipped with a flange at a location above its lower surface, and this again increases the length of the shortened umbrella.

The invention entirely abandons the hitherto customary idea of attaching the carrying loop to the lower surface of the grip by means of a button. Instead of this, pocket umbrella having a stick and at the lower end of the stick a handle with a carrying loop the ends of the carrying loop are attached to the handle adjacent to the periphery of the handle.

In those umbrellas which have no push button for nite States Patent unlocking the stick parts it is then no longer necessary to provide any button at all. However the advantages provided by the invention are obtained in the highest degree in the case of umbrellas in which the stick is found in a number of telescopic parts with a lock for locking adjacent parts together, the lock being released by operation of a push button in the centre of the lower end of the handle. A push button of this kind can be mounted in a lower surface of the grip which is dished, so that the button hardly increases the length of the umbrella. The button need project only just far enough to allow the operator to release the lock, because the button has no transverse drilling to accommodate a key ring.

Patented Oct. 21, 1969 "ice In view of the fact that the carrying loop is not attached to the push button, the latter is not constantly subjected to torques, and it need therefore not be attached to the unlocking rod in customary way. This considerably simplifies the construction and the button may be a force fit on the end of the unlocking rod. This method of assembly is very simple and can be completed in one movement.

In order to allow easy removal of the button during maintenance operations, there are preferably two axial passages in the handle in order to allow a special tool to be inserted.

The handle may have a flange formed with two axial slots into which the ends of the carrying loop are inserted and secured by means of terminal pieces. The terminal pieces may be concealed from sight in the slots, by projecting laterally from the ends of the loop and being supported against shoulders in the slots in the flange.

One example of a telescopic umbrella frame constructed in accordance with the invention is illustrated in the accompanying drawings which are drawn to twice natural size in order to reveal the details clearly, and in which:

FIGURE 1 is a longitudinal section through the handle together with part of the stick and loop; and

FIGURE 2 is a side view in the direction of the arrow II in FIGURE 1, a part of the flange of the handle being cut away along the line AA, so as to reveal the method of attachment of the carrying loop.

The handle in this example consists of a plastic end piece 1, on which is mounted a hollow cylinder 2, which can be of plastic or metal. The cylinder 2 is firmly attached to the end piece 1. The lower end 3 of the telescopic umbrella stick is mounted in the end piece 1 and secured by an internally threaded nut 4, which screws over the end of the tube 3. A transverse pin 5 is mounted in a transverse drilling in the tube 3 so that when the nut 4 is tightened the pin 5 is pulled firmly into contact with the end piece 1, which contains a transverse groove 5a to accommodate the pin 5, preventing the pin from rotating. Between the head of the nut 4 and the end piece 1 there is an intermediate washer 6.

The end piece 1 has a narrow flange 7 through which there penetrate at opposite sides two narrow axial slots 8. Each slot has wider upper end, forming sunken shoulders 9. The two ends of the carrying loop 11 are inserted in the slots 8. There are then attached to the ends 10 of the loop terminal pieces 12, which are wider than the carrying loop itself. The ends of the pieces 12 rest on the shoulders 9, Where they are invisible from the outside.

The stick to which the grip is attached is equipped with an unlocking rod 13, which is used for unlocking the lock between the telescopic stick parts. The unlocking rod 13 is actuated by a plastic push button 14, which has a shaft 15 which slides up and down in the nut 4. The shaft 15 has a longitudinal drilling 16 so dimensioned that the push button 14 can be forced over the end of the unlocking rod 13, to give a tight fit. A frictional connection between the push button and the unlocking rod is suflicient, because the push button is never subjected to a pull, in contrast to the case of umbrellas in which the carrying loop is attached to the push button.

To allow the push button to be removed from the end of the unlocking rod 13 during maintenance operations, the end piece 1 has two axial drillings 17, to allow introduction of two pins on a special tool, for the purpose of forcing the push button 14 off the end of the unlocking rod 13. The bottom surface 18 of the end piece 1 is countersunk, so that the push button 14 projects downwards only a little beyond the lower edge of 3 the end piece 1. The arrangement still allows plenty of room for the push button 14 to be pushed in by an operators finger, for the purpose of unlocking the locks between the stick parts.

I claim:

1. A pocket umbrella frame comprising a stick, a handle fixed to one end of said stick, and a carrying loop having ends secured to said handle, said handle being formed with a substantially cylindrical flange portion having a pair of diametrically opposed slots extending axially therethrough and located adjacent the peripheral surface of said substantially cylindrical flange portion, said flange portion being formed with internal shoulders respectively dividing said slots into a narrower and wider slot portion located at opposite axial ends of said flange portion, said ends of said carrying loop extending respectively into and through said narrower slot portions and terminating in said Wider slot portions, and terminal pieces fastened respectivel to said ends of said carrying loop and extending transversely to said loop within the respective wider slot portions so as to abut against the respective internal shoulders.
