- In Germany February 21, 1933 6 Claims.

This invention relates to an umbrella of the kind provided with telescopically adjustable stick and rib sections and wherein auxiliary struts are employed which. are pivoted at one end to the stretchers and at the other end to a separate most stick section wherein'the spring catch is enclosed together with a slide which projects through the end of the handle and which, when pushed inwards, engages and retracts the spring catch and allows the stick to collapse.

Apart from the fact that the catch can thus be retracted by a mere pressure exerted on the end of the handle, the umbrella cover will be prevented from coming into contact with and be damaged by the catch when the stick collapses.

Fig. l of the accompanying drawing represents a sectional view of the extended stick and innbrella frame,

Fig. 2 is a view showing the umbrella in telescope position,

Fig. 3 is a view of the slide whereby the catch is released,

Fig. 4 is .a sectional view on an enlarged scale illustrating the connection of the handle to the stick, and

Fig. 5 is a plan view of the handle.

The umbrella comprises a telescopic stick composed of three tubular sections I, 2 and 3. A spring catch 4 in the intermediate section 2 maintains the top section I in extended position, and the intermediate section .2 is maintained in extended position by means of a spring catch 5 housed in the lowermost section 3. The umbrella ribs are each composed of two telescopically adjustable sections 9 and. II]. The inner section 9 is hinged to the crown 8 and carries at its free end a ring I I wherein the rib section It! is guided. A sleeve I2 connected to the section [0 rides, as an additional guide, on the section 9. The stretchers M of the umbrella are pivotally connected at one end to the sleeve l2, as shown at l3, and at the other end to a runner l5. Each stretcher is supported by an auxiliary strut I! which is pivoted to the median portion of the stretcher. All the struts are pivoted to a separate runner i 8 which bears against the crown 8 when the umbrella is open. In the closed position of the umbrella, the runner I8 is situated on the stick section 2, as shown by dotted lines in Fig. l, and the runner i5 is engaged by a spring catch 5, l6 fitted in the stick section The telescoping oi the umbrella requires a retraction of the catch 5 which is somewhat inaccessible since it is hidden behind the frame members and the um brella cover. To facilitate the retraction of the 10 spring catch, a hollow slide 23 is provided which is enclosed and guided in the stick section 3 and adapted, on inward displacement; to engage and retract the spring catch. The slide projects for this purpose through the end or" the um- 15 brella handle 5 which is connected to the lower end of the stick section 3. The slide partly encloses the spring catches 5 and i6 and is provided with elongated slots 24 and 25 through which the springs project. I

The presence of the slide requires a modification of the usual handle construction. According to the invention a hollow guide member 29 for the slide 23 is inserted through the lower end of the handle sleeve 8 and screwed on to the end 38 25 of the stick section 3. The latter and the guide 7 member meet within acylindrical spacing member 1 which is made of wood or other suitable material and firmly secured to the handle sleeve 6. A cross pin 26 in the stick section bears against 30 the outer end of the spacing member 1, and the guide member 29 is fitted with a head 3| which bears against the end of the handle sleeve for. holding the pin against the spacing member and ensuring a rigid connection of the stick to the handle. The spacing member is provided with a groove 32 in which the pin 26 is accommodated so that rotary displacement of the stick relative to the handle will be prevented. The slide 23 has an elongated slot 2i by means of which it is 40 guided on the pin 26, and a spring 22, which bears at one end against the pin 26 and at the other end against the closed end 28 of the slide, tends to maintain said end in a projecting position relative to the handle, so that it can be readily dis-' placed for retracting the spring catch 5.

The retracted spring catch will be unable to contact with and damage the umbrella cover when the umbrella collapses. The spring catch it will also be moved out or reach of the cover when the umbrella collapses, it being for this purpose adapted to be retracted and covered by the stick section 2 the lower end of which enters the handle 6.

' The stick section 2 is fitted with a spring 20 which carries a lug 2i adapted to engage in a slot in the stick section I and prevent relative rotary motion of the stick sections. On the umbrella being collapsed, the lug 2| snaps into a corrugation 33 in the upper part of the stick section I and retains the latter so that, on the umbrella being re-extended, the section 2 will be induced to move first and clear the spring catch l6 for the retention of the runner i5. a

The rib sections H] are each provided with a bend 19 which is normally situated behind the ring H and has to pass through the latter on the umbrella being telescoped. By' the engagement of the bend with the ring, a braking action is obtained which prevents the ribs from collapsing when the runner i5 is pushed for opening the umbrella. The arrangement for releasing the catch 5 has the further advantage that, as it allows the umbrella to be constructed so that the cover will remain straight in the normally closed position of the umbrella, the cover can dry without much shrinking, thereby relieving the ribs of excessive stress when the umbrella is reopened.

I claim:

1. A telescopic umbrella of the character described, comprising a plurality of tubular stick sections, a hollow handle secured to the lowermost stick section, a spring catch enclosed in said to the outer end of the lowermost stick section and connecting the handle thereto, the said slide passing through the same.

3. A structure as claimed in claim 1 wherein the handle comprises a, sleeve, a cylindrical spacing member arranged in and secured to said sleeve and enclosing the end of the stick section, a headed guide member for the slide screwed on to the end of the stick section and bearing with its head against the outer end of the sleeve, and a cross .pin in the stick section bearing against the upper end of the spacing member.

4. A structure as claimed in claim 1 wherein the handle comprises a sleeve, a cylindrical spacing member arranged in and secured to said sleeve and enclosing the end of the stick section, a headed guide member for the slide screwed on to the end of the stick section and bearing with its head against the outer end of the sleeve, and a cross pin in the stick section bearing against the upper end of the spacing member, said spacing member having a groove in which said crosspin is accommodated for preventing rotary displacement of the stick relative to the sleeve.

5. A structure as claimed in claim 1 wherein the slide partly encloses the spring catch and is slotted to enable the latter to be fastened to the surrounding stick section.

6. The structure of claim 1, together with a hollow member provided at one end with a head and being at its other end screw-threaded and united by screw-thread engagement with thelowermost stick section and by means of such screw-thread union together with its headed formation adapted to effect the clamping of the lowermost stick section to the handle, the said slide extending beyond the lowermost stick section and through the said hollow member.
