Description
March 12, 195? A, VLKER TELESCOP-IC UMBRELL Filed July 14, 1953 United States Patent O TELESCOPIC UMBRELLA Alois Vlker, Leichlingen, Rhineland, Germany, assignor to Rosenkaimer G. m. b. H., Leichlingen, Rhineland, Germany, a firm Application July 14, 1953, Serial No. 367,886
Claims priority, application Germany July 18, 1952 1 Claim. (Cl. 13S- 20) The invention relates to a telescopic umbrella having telescopic cover ribs and stick members.
Telescopic umbrellas have to meet the demand that the umbrella has to be as long and wide as possible in the stretched or open position while the size has to be reduced to a minimum in the telescoped position. It is possible with such umbrellas in which the inner stick member is adapted to be telescoped into the outer stick member, to telescope the inner stick member until the outer end of said inner stick member reaches the outer end of the outer stick member, this action being possible as the crown is recessed to receive said outer end. But it is quite another thing if the stick members are arranged in such a manner that the outer stick member is adapted to be telescoped into the inner stick member. ln this case the inner stick member surrounding the outer stick member is adapted to be displaced only until striking the crown. This means that shortening of the stick members cannot be effected to such a degree as in the rst case.
The invention provides a way to effect shortening of the stick members to a minimum even with that arrangement in which the outer stick member is adapted to be telescoped into the inner stick member. An essential feature of the invention is that the crown which is attached to the outer stick member has an inside diameter of such dimension that the inner stick member is adapted to be telescoped into the crown when telescoping the stick members. Therefore the inner stick member may be as much longer at least than the outer stick member as is required for telescoping the inner stick member into the crown. The result is an umbrella stick which is as long as possible in the extended position of the stick members which permit full shortening of the same cven if the inner stick member has a greater diameter than the outer stick member.
The attachment of such a crown having a greater inside diameter than the upper stick member may be etfected by means of a sleeve whose diameter corresponds to that of the inner stick member. Preferably there is used a crown, the upper end of which is provided with a protruding inner collar made of one piece with the crown which is immediately contacted by the outer stick member. The crown is further provided with an annular aperture for engagement with the inner stick member.
Two embodiments of the object of the invention are shown by way of example in the drawing.
Fig. 1 shows a telescopic umbrella having the features according to the invention.
Figs. 2 and 3 illustrate design and attachment of the crown to the outer stick member as well as the engagement of the inner stick member.
In Fig. 4 is shown the preferred embodiment of the crown according to the invention.
iatented Mar. 12, 1957 The telescopic umbrella is provided in a manner known per se with stick members 1, 2 and also with cover ribs 3, 4 adapted to be telescoped. The cover ribs are articulated to the crown 5. The displacement of the cover ribs is etected by means of the slide member 6 which is connected by means of struts with the inner ends of the outer cover ribs 4. The embodiment illustrated by way of example shows an umbrella which is selfopening by means of a spring 7 arranged on the main slide member 6. For this purpose main struts 9 lead from `the spring pressed auxiliary slide member 8 to the cover ribs 4 while auxiliary struts 10 are connected with the inner slide member 6 and the struts 9` intermediate the ends of the latter.
The construction of the umbrella is such that the outer stick member 1 is adapted to be telescoped into the inner stick member 2. Arresting of the stick members in the stretched position is eected by means of ball catches 11 known per se. According to the invention, crown S is `designed in such a manner that it has formed therein an opening 20 of a diameter which permits the inner stick member 2 to telescope into the annular space 12 nearly to the end of the outer stick member 1. Crown 5 is centered with respect to the outer stick member 1 by means of an intermediate sleeve 13 Whose diameter may correspond to that of the inner stick member. A pin 15 serves for attachment of the intermediate sleeve 13 and of the crown 5 to the outer stick member. The pin is suitably riveted at both ends. The reference numeral 14 designates the closure cap screwed upon the crown.
According to Fig. 4, the upper end of crown 16 is provided with an inwardly and axially directed annular collar 17 which immediately contacts the outer stick member 1. The attachment is effected by means of pin 15. In this embodiment the former parts 5 and 13 are made of one piece. The crown is advantageously made by die casting. It will be noted that the annular collar 17 serves to space the outer stick 1 from the walls of the opening 20, and also serves as a stop for the outer end of the inner stick 2 when the umbrella is collapsed.
I claim:
A crown structure for telescopic umbrellas having inner and outer telescopic stick members, including a cylindrical body portion, said body having a central opening therein with the outer end of said outer umbrella stick member anchored in said opening and spaced from the wall of said opening, said crown having an annular collar at the outer end thereof extending axially therefrom and projecting inwardly into engagement with the outer end of said outer stick member, the outer end of said outer stick member terminating substantially at the outer end of said collar, and an anchor pin extending through said collar and said stick member, the said collar thereby serving as spacing means for the outer stick member, as stop means for the inner stick member, and as anchor means for the outer end of said outer stick member.
