J. C. WlTTY Sept. 8, 1953 UMBRELLA Filed June 28, 1.950

INVENTOR. JAMES c. WITTY 9M ATTORNEYS Patented Sept. 8, 1953 UMBRELLA James O. Witty, Troy, Ohi

Sunshade Company,

of Ohio 0, assignor to The Troy Troy, hio,'a corporation Application June 28, 1950, Serial No. 170,819 1 Claim. (01. 135-20) This invention relates to umbrellas, and more particularly to umbrellas of comparatively large size such as beach or garden umbrellas or the like.

Considerable difficulty is sometimes encountered in raising and collapsing large umbrellas owing to the substantial amount of force required to produce the tension in the ribs for holding the canopy properly in use. It is frequently impossible, particularly for a woman or child, to raise or lower the canopy of such an umbrella while the standard is erect, since only by inverting the standard and pressing against the ground or some other abutment can sumcient force be developed to overcome the rib tension. It is also diflicult to collapse the umbrella top, and this operation is attended by considerable possibility of pinching the fingers or otherwise suffering discomfort. Also another difiiculty in raising and lowering a conventional beach or garden umbrella is that the large radius of the canopy requires the force on the part of the user to be exerted at a very awkward angle and frequently when off balance.

The present invention overcomes these well known difilculties and inconveniences of the conventional beach umbrella structure by providing an umbrella which can be conveniently erected when the standard is upright and in which'the main force required for erection is exerteddownwardly along the standard. This simple and easy operation is obtained by providing an axially movable extension on the upper end of the standard and securing the top crown to this extension instead of to the standard. With this construction, when the canopy is to be erected and the runner is moved to its raised position in the usual way, the extension and top crown move with respect to the standardto an upper position in which the canopy is fully are undersubstantially no tension. Erection of the top is then completed by pulling down on the extension, as by means of a suitable cord or chain, to develop the proper tension in the ribs, and the extension is then retained in this lower position for use of the umbrella.

It will be seen that with this construction and operation, the standard can readily be set in the ground in upright position after the runner has been raised, which requires comparatively little force, but while the extension is still in its upper position and the ribs are not under tension. Movement of the extension to its lower position can then be efiected by pulling directly downwardly from a convenient position below the canopy and adjacent the standard, which is conextended but the ribs an umbrella construction of the tion as to maintain the 2 siderably more comfortable for the user and also may be done without the dangers of pinched fingers or the like commonly encountered with the usual construction. Collapsing of the umbrella is equally simple and convenient, it being necessary merely first to release the extension releasing tension in the ribs, after which the runner is released and retracted in the usual way.

It is one of the principal objects of the present invention to provide an umbrella construction umbrella is similarly accomplished by first pulling downwardly on a movable member.

Another object of the invention is to provide such an umbrella construction which does not tional umbrellas.

It is also an object of the invention to provide above type in which the canopy is simple and easy to raise or collapse while the standard is in an upright position and in which the force required for raising and collapsing the top is exerted in such direcstandard upright.

Other objects and advantages of the invention will be apparent from the following description, the accompanying drawing and the appended claim.

Fig. 2 is a fragmentary view on an enlarged scale showing the structure and operation of the umbrella frame;

lt willl accordingly beeseemthattthis umbrella construction has outstanding advantagespf simplicity and ease in use. Erection and collapsing ofithe umbrella top are easily effected with comparatively little efiort while the standard is upright, and at the same time the effort which is reduiredfisssotdirectedas to avoid uncomfortable ors-awkwardimovements or position on the part of the user. Also; this umbrella construction is considerably easierrto handle in the wind such as is often encountered on a beach, since if desired the standard can be firmly set in the ground before the top is raised at all, and the same is true onthepperationiofdoweringthetop.
