Description
PUSH BUTTON FOR A SELF-OPENIN~ UMBRELLA
This invention relates to umbrellas. More particularly, this invention relates to a control push button for an automatic umbrella.
In one conventional automatic umbrella, and as shown in Figs. 11-14, a spring loaded latch arm A
is pivotally connected to the bottom end of a hollow centerpost C fixed to an umbrella handle B. A push button E is located in push button hole D at one side of the handle B. Motion of the spring loaded latch arm A is controlled by depressing the push button E.
The configuration of the conventional push button hole D is designed to match the configuration of the conventional push button E to allow assembly of the push button with the handle B. The outside of the push button E is stepped, as shown in Figs. 12-14, so that the push button E is supported by the interior surface of the handle's wall to prevent the push button from escaping when the push button is inserted into the push button hole D from inside the handle.
Hence, and when the push button E is depressed during use, it needs the edges of the hole D in the wall of the handle B to support the push button and to prevent the push button from escaping or tilting, as shown in Figs. 13 and 14. However, and since the wall of the handle B is relatively thin, during repeated use there may be wear on the handle hole D which may adversely affect subsequent use of the latch arm A that controls automatic opening of the umbrella. Another trouble-some problem also occurs with the conventional push button E. When assembling the umbrella, the push button E must first be placed into the push button hole D of the handle B from the interior of the handle B, and thereafter the hollow centerpost C and the latch arm A are assembled with the handle s. Since lS the open throat of the handle B is not large, it is difficult to manually mount the push button E from the interior of the handle through the hole D. Further, and since the push button E is the first component mounted in the handle B when assembling the umbrella, the push button is often inadvertently touched there-after as assemblv of the umbrella continues, and this may prove troublesome or inconvenient in final assembly of the other umbrella components. A further problem occurs with the self-opening or automatic umbrella during its packaging and/or shipment in that if the push button E is inadvertently touched the umbrella will open immediately.
Accordingly, the primary objective of this invention is to provide an improved push button for an umbrella that can be operatively located in a push button hole from the exterior of the umbrella's handle, and which can be located in that push button hole at any desired time during or after assembly of the umbrella. In this regard, the push button of this invention is provided with a latch section that allows the push button to be easily inserted into the push button hole from outside the handle, and that prevents the push button from escaping the push button hole once it is assembled with the handle.
Another objective of this invention is to provide an improved push button for an umbrella where that push button includes a flexible latch section defined by opposed clamping lugs. Each clamping lug has an inclined entry portion, and a clamping portion adjacent to the entry portion, located on its inner side surface. When the push button is pushed into a push button hole from the outside of a handle, the inclined entry portions of the clamping lugs allow the lugs to flex and slide past a centerpost attached to the handle to a position where the clamping portions rest against the centerpost, thereby gripping the centerpost between the two clamping lugs. In use, the clamping lugs and the push button cooperate to control a spring loaded latch arm member within the interior of the centerpost because the push button is seated against the latch arm when the clamping lugs are assembled with the centerpost.
A further objective of this invention is to provide an improved push button for an umbrella where that push button includes a flexible latch section defined by opposed clamping lugs. Each clamping lug has an inclined entry portion, and a clamping portion adjacent to its entry portion, located on its outer side surface. When the push button is pushed into a push button hole from the outside of a handle, the inclined entry portions of the clamping lugs allow the lugs to easily flex and slide into and through a push button hole in the handle where the clamping portions rest against the inside surface of the handle, thereby holding the push button in assembly with the handle.
In use, the push button and the clamping lugs cooper-ate to control a spring loaded latch arm within the interior of the centerpost because the push button is seated against the latch arm when the clamping lugs are assembled with the handle.

The push button 10 of this invention, as shown in Figs. 1-10, is assembled with a handle 20 to control a spring biased latch arm. The push button can be of various shapes, e.g., square, circular or triangular shape. The merits of this invention, however, will be explained by referring to embodiments which adopt a square push button. Further, the push button structure of this application can be used with automatic or self-opening umbrellas having various types of cover rib linkage systems.
In the first push button 10 embodiment shown in Figs. 1-3, a flexible latch section that includes a pair of opposed flexible clamping lugs 12 extend from the inner surface of the push button body 11, the lugs being adapted to flex in a direction normal to the handle's longitudinal axis. A push button hole 21 is provided at one side of the umbrella handle 20 for the insertion of the push button 10. Each clamping lug 12 is provided with a latch section which includes an inclined entry portion 13 at its end on its inside surface, a clamping portion 14 adjacent to the in-clined entry portion 13 also on its inside surface.
Note the outside breadth of the clamping lugs 12 is less than the width of the button hole 21 so the lugs can extend thereinto from outside the handle 20 without interference. Note also the gap between the clamping lugs 12 is of a width about equal to the diameter of centerpost 22 so the clamping lugs can be clamped thereon when assembled therewith. In assembly, the centerpost 22 is first installed in the handle 20 with a spring biased latch arm 23 being provided therein as shown in Figure 1. The latch arm 23 includes a projection 24 oriented to face the push button hole 21. Hence, when the push button's latch section with clamping lugs 12 is pushed into and through the push button hole 21, the clamping lugs inclined entry portions 13 allow the lugs 12 to flex over and around the centerpost 22 until the button's inner body surface is seated against the latch arm's projection 24, compare Fig. 2 to Fig. 3. In this final assembly position, the clamping lugs 12 grip the centerpost 22 therebetween with same being held clamped thereto by the clamping lugs' clamping portions 14. In use, and as can be seen from Fig. 3, the latch arm 23 can be pivoted from a latch or umbrella storage position (shown in Fig. 3) to an unlatch or umbrella extend position (not shown) simply by pushing the push button into the handle 20 until the button's inner body surface abuts the centerpost 22. This travel motion is permitted because of the length of the clamping lugs 12, i.e., because of the length of the lugs' arms between the push button's inner body surface and the lugs' latch sections 14.
In the second push button 10 embodiment shown in Figs. 4-7, the flexible latch section in-cludes a pair of opposed flexible clamping lugs 12 that extend from and comprise part of the side walls of the push button body 11, the lugs being adapted to flex in a direction normal to the handle's longi-tudinal axis. A push button hole is provided at one side of the umbrella handle for the insertion of the push button 10. Each clamping lug 12 is provided with a latch section that includes an inclined entry portion 13 at its outside surface, and a clamping portion 14 adjacent to the inclined entry portion 13 also on its outer surface. Note the outside breadth of the clamping lugs 12 is substantially equal to the width of the push button hole so the clamping lugs can extend thereinto without interference from outside the handle 20 except for certain latch structure on the exterior surface of those lugs 12. Note also the push button includes a central finger that extends from the button's inside body surface that is adapted to contact the latch arm's projection 24 as described below. In assembly, the centerpost 22 is first installed in the handle 20 with the spring-biased latch arm 23 being provided therein as shown in Fig.
4. The latch arm 23 includes the pro~ection 24 oriented to face the push button hole 21. Hence, when the latch section with clamping lugs 12 is pushed into and through the push button hole 21, the clamping lugs' incline entry portions 13 allow the lugs 12 to flex inwardly through the hole until the latch sections 13, 14 clear that hole and the push button's inner finger is seated against the latch arm's projec-tion 24, compare the installation sequence illustrated in Figs. 5 to 6 to 7. In this final assembly position, the clamping lugs 12, as shown in Fig. 7, are seated against the inside surface of the handle with the push button in the ready position, and with the push button being held in clamped relation with the handle by the clamping lugs' clamping portions 14.
In use, and as can be seen in Fig. 7, the latch arm can be pivoted from a latch or umbrella storage position ~shown in Fig. 7) to an unlatched or umbrella extend position (not shown) simply by pushing the push button 10 into the handle until the button finger's inner surface 15 abuts the centerpost 22. This travel motion is permitted because of the length of the clamping lugs 12, i.e., because of the length of the lugs' arms between the lugs' latch section 14 and the push button's outer body surface.
In the third push button embodiment shown in Figs. 8-10, the push button structure is generally similar to the second embodiment shown in Figs. 4-7 except the push button structure has been re-oriented or turned 90. More specifically, in the third embodiment the push button's flexible latch section includes a pair of opposed flexible clamping lugs 12 that extend from the top and bottom surfaces of the push button body 11, the lugs being adapted to flex in a direction parallel to the handle's longitudinal axis. A push button hole is provided in one side of the umbrella handle 20 for insertion of the push button. Note the outside breadth of the clamping lugs 12 is essentially the same but slightly less than the height of the button hole 21 so the lugs can extend thereinto without significant interference from outside the handle except for the lips' latch sections. Each clamping lug 12 is provided with a latch section that includes an inclined entry portion 13 at its end on its outside surface, and a clamping portion 14 adjacent to the inclined entry portion 13 also on its outside surface. Note as in the second -embodiment, a finger extends from the push button's inner surface, and that finger surface 15 is adapted to cooperate with the latch arm's projection 24 as explained in detail below. In assembly, and as with the other embodiments, the centerpost 22 is first installed in the handle 20 with the spring biased latch arm 23 being provided therein as shown in Fig.
8. The latch arm 23 includes the projection 24 oriented to face the push button hole 21. Hence, when the latch section with clamping lugs 12 is pushed into and through the push button hole, the clamping lugs' inclined entry portions 13 allow the lugs 12 to flex inwardly relative to the hole's outer edges until the button's fingers inner end 15 is seated against the latch arm's projection 24, compare Fig. 9 to 10. In this final assembly position, the clamping lugs 12 are flexed outwardly, as shown in Fig. 10, so the push button cannot be pulled out of the handle. In use, and as can be seen also from Fig. 10, the latch arm 23 can be pivoted from a latch or umbrella storage position (shown in that Fig. 10) to an unlatch or umbrella extend position (not shown) simply by pushing the push button 10 into the handle 20 until the button finger's inner surface 15 abuts the centerpost 22.
This travel motion is permitted because of the length of the clamping lugs 12, i.e., because of the length of the lu~s' arms between the lugs latch sections 14 and the push button's outer surface.

A push button hole 21 is provided at one side of the umbrella handle 20 for the insertion of the push button 10. Each clamping lug 12 is provided with a latch section which includes an inclined entry portion 13 at its end on its inside surface, a clamping portion 14 adjacent to the in-clined entry portion 13 also on its inside surface.
