Claims  |
|
|
What is claimed is:
1. A tool handle adapted to telescope over the end of a pool pole, said
handle having adjacent its distal end a pair of diametrally opposed first
apertures, and having adjacent thereto and aligned therewith a pair of
diametrally opposed second apertures, and a wishbone-like spring member
positioned within said handle by a pair of outer opposed thumb buttons
carried thereby and extending into said first apertures and by a pair of
inner opposed locking buttons carried thereby and extending into said
second apertures, said thumb buttons being greater in axial length than
said locking buttons whereby a conjoint but partial depressing of said
thumb buttons frees said locking buttons from said second apertures while
said thumb buttons still extend into said first apertures, said spring
member being freeable for removal from said handle by a conjoint and
substantially full depressing of said thumb buttons to free the same from
said first apertures, said handle being attachable to said pool pole by
means comprising a pair of diametrally opposed third apertures formed in
said pole adjacent the distal end thereof and by said locking buttons
which are adapted to extend through said third apertures and into said
second apertures.
2. The tool handle of claim 1, said handle having adjacent its proximal end
a pair of diametrally opposed fourth apertures corresponding in size to
said second apertures. |

Description  |
|

BACKGROUND OF THE INVENTION The invention relates to the provision of means
whereby a pair of telescoping tubular members may be quickly connected
against movement apart and quickly disconnected for removal apart.
It is old in this art to connect a tubular tool connector, or handle, to a
tubular pool pole by providing the former with a pair of opposed
spring-urged locking buttons which fit within opposed apertures in a pool
pole to releaseably connect the handle and pole together.
It is also old in this art to mount the button-carrying spring member
within the inner telescoped tubular member and to provide the spring
member with operating thumb buttons which extend through a second set of
apertures in the inner member, i.e. the pool pole.
SUMMARY OF THE INVENTION
The present invention differs from the above-described prior art in that
the spring member carrying the locking buttons and thumb buttons is
carried by the outer, or handle member so that conventional domestic pool
poles may be used. The handle member is further provided with a pair of
locking button apertures adjacent its free end. This enables the handle
member, upon removal therefrom of the button-carrying spring member, to be
used with foreign pool poles which carry such spring members.

separated condition.
FIG. 2 is a view in longitudinal section of the elements of the invention
in connected relation.
FIG. 3 is a view taken along lines 3--3 of FIG. 2.

DESCRIPTION OF PREFERRED EMBODIMENT
With reference to the drawing, the connector comprises pool pole 10 which
is provided with pairs of apertures 12 and 14, tool handle 16 which is
provided with pairs of apertures 18, 20 and 22, and a spring member
indicated generally at 24. The member 24 is unitary and wishbone-shaped in
form comprising arms 26 and 28, locking buttons 30 and thumb buttons 32.
The member 24 is preferably formed of a tough, flexible plastic such as
DELRIN. It is provided with a reinforcement-gripping tab and pole guide 34
and with reinforcement ribs for the arms 24 and 28. The handle 16 is
provided with a pair of arms 38 whereby the handle may be attached to, for
example, a brush 40.
The member 24 is normally attached to the handle so that the thumb buttons
32 extend through the apertures 18 and the locking buttons 30 extend
through the apertures 20. This is accomplished by pressing the arms 26 and
28 against each other, sliding the compressed member into the handle 16,
and rotating the member by twisting the tab 34 to permit the thumb buttons
32 and the locking buttons 30 to snap into their respective apertures 18
and 20. The pole 10 is then attached to the handle by depressing the thumb
buttons 32, as shown in FIG. 4, and sliding the pole 10 into the handle 16
to align the apertures 12 and 20, followed by release of the thumb buttons
to cause the locking buttons 30 to extend through the pole apertures 12
and into the handle apertures 20. The pole 10 is now locked to the handle
16. Disconnection of the pole and handle is effected by depressing the
thumb buttons 32, as shown in FIG. 4, and by withdrawing the pole from the
handle.
Pool poles in this country are normally provided with the two pairs of
apertures 12 and 14. The placement of the spring member 24 within the
handle 16 renders the latter particularly adaptable for use with the
conventional domestic pool pole, as above-described.
As previously pointed out, some foreign pool poles, as for example in
Australia, have the member 24 installed with the tab 34 adjacent the
distal end of the pool pole, with the locking buttons 30 connected to a
pair of apertures corresponding to apertures 14, and with the thumb
buttons 32 connected into apertures like apertures 18 which are formed to
the right of apertures 14, with reference to FIG. 1.
The spring member-containing handle 16 is readily adaptable for use with
such a spring member-containing pool pole by removing the spring member 24
from the handle 16 and discarding it and by connecting the pole to the
handle so that the locking buttons extend through the pole apertures 14
and through the apertures 22 of the handle.
