Application October 20, 1947, Serial No. 780,790 z claims. (ol. 13s-41) This invention relates to devices for retaining an umbrella in open and closed position, and particularly in a unit device mounted upon the shaft or rod of the umbrella and operatively engaging the same to retain the umbrella in open and closed positions. The novel lfeatures of the invention will be best understood from the following description when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views; and in which:

Fig. 1 a longitudinal sectional view through a device mounted upon the umbrella rod, showing parts of the umbrella in a partially open postion; and

2 is a side elevation of the structure shown in Fig. l, with parts omitted.

In the drawing, shown at. 5, is the stick, shaft or rodv of an umbrella and in Fig. 1, is shown at I two of the brace rods of the umbrella ribs, the remainder of the umbrella being omitted, as it is all well known in the art. At 'I' is shown the unit latching, clamping or locking device for retaining the umbrella in the open and closed positions in the accompanying drawing, the parts are shown, for sake of clarity,

in what might be termed an intermediate position or the position assumed in the operation of moving the umbrella from the closed to the open position and` about to reach the limit of the open position.

'I 'he unit device 'I comprises a central body portion 8 having an outwardly flared collar 9 forming a finger grip portion. Above the iin.- ger grip portionis an anuular recess I0 in which` is secured the usual rod supporting ring I I, commonly employed in umbrellas and to which the brace rods I5 are pivotally coupled in the circumferentially spaced sockets I2 thereof through the medium of a wire I3. Above the ring I I, the part- 8v has a sleeve portion I4 in which is slidably mounted a short tubular plunger part I5 within whichy is arranged a coil spring I6. One end Il of the spring I6 extends through an aperture in the part I5 and the other end I8 extends through the sleeve I4, this holds the parts in assembled relationship while at the same time permitting inward or downward movement of the plunger part I5 in the operation of the device,Y as later described.

The part. 8v below the collar 9 has two bevelled or conical surfaces` I9 and 20 which can be termed upper and lower surfaces, the surfaces being joined by an enlarged intermediate portion. vThe lower end of the part 8 terminates in an out.r wardly extending annular flange as at 22. This` flange operates in the recess or channel 23 of a gripper part 24. The gripper part comprises aninner tubular portion 25 and an outer tubular portion 26, the latter terminating at its upper end in an outwardly flared collar 21, similar to the collar 9 and forms a ngerpiece facilitating operation of the device. The walls 25 and 26 are joined at their lower end by a bottom wall 28 upon which seats a coil spring 29, the upper end ofY the spring seating upon the flange 22. The inner wall 25 termina-tes at its upper end in a pluralityl of circumferentially spaced gripper fingers 3l! having at their free ends outer rounded surfaces. as at 3I.- These surfaces are adapted to move over the bevelled surfaces I9 and 20 in forcing the grippers 3S inwardly to firmly grip the stick or shaft 5. The upper end portion of the stick or shaft 5 has an outwardly projecting stop pin 32 which is adapted to be engaged by the plunger part I5 as the device is moved upwardly on the shaft preparatory to moving the grippers 30 i into operative position.

In the aforesaid. operation, the part 24 is engaged by the fingers of the hand in sliding thev device upwardly and longitudinally of the shaft and on completing the upward movement, theplunger part I5 strikes the pin 32, thus compressing the spring I6 sufficiently to apply downwardA pressure to the member or part 8 with the fingers of the hand engaging the gripper 24. It willbe apparent that the spring 29 will be compressed, being of lighter tension than the compressed spring I6 and the gripper fingers 30 arey then moved upwardly into engagement with the bevelled surface I9 and forced into firm operative engagement with the shaft or stick 5.

The rib bracing rods 6 are also tensioned and exert a downward pressure on the part 8. It will thus be ,apparent that the` umbrella is then rmly locked in its open position. To close the umbrella, the ngers of the hand are placed with the part v8 beneath the collar 9. and the collar 9 is pushed upwardly against theY action of the spring I6. This then releases ther gripper fingers 30, the spring 29 moving the gripper part 24 downwardly to the neutral position`- shown in Fig. l, whereupon the device can be freely moved longitudinally of the shaft and in reaching the closed position the spring 29 is of sufficient tension to move the ngers 30 downwardly into engagement with the bevelled surface 20 to again move the fingers 30 inwardly 3 to grip the shaft, thus holding the umbrella in closed position.

It will appear that the complete device comprises a preassembled unit which as such, can be mounted upon the shaft of the umbrella and thereupon, the brace rods B of the umbrella rib are attached. It will also be understood that a structure of this type and kind dispenses with the mounting of clasp or other latch members upon the shaft of the umbrella and the labor essential to form the shaft for reception of such devices and the attachment of the devices thereto. It will, therefore, be apparent that the cost of producing the complete umbrella is materially simplified.
