ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a juicer with an easy-to-assemble pivotal connection for the handle of the juicer, providing a simple structure and allowing easy assembly of the juicer.
2. Description of the Related Art
FIGS. 1 and 2
of the drawings illustrate a conventional juicer of the type having a Y-shaped handle
15
for saving force when pressing fruit. The juicer comprises a base
11
, a column
12
extending upright from a side of the base
11
, a head
13
securely attached to an upper end of the column
12
, a vertical rod
14
extending vertically through the head
13
, and a Y-shaped handle
15
for effecting vertical movement of the vertical rod
14
. A detachable pressure cup
142
is attached to a connecting member
141
mounted to a lower end of the vertical rod
14
. A bracket
16
is attached to an intermediate portion of the column
12
for receiving fruit to be pressed by the pressure cup
142
.
The head
13
includes a pivotal section
132
having a transverse hole
131
in which a sleeve
133
is mounted, the sleeve
133
having an inner threading. The connecting member
141
of the pressure cup
142
includes a screw hole
143
. The Y-shaped handle
15
includes a main section
151
and two arms
152
branching off from an end of the main section
151
. A bolt
2
is extended through the sleeve
133
that extends through the distal ends of the arms
152
such that the handle
15
may pivot about a longitudinal axis of the bolt
2
. An intermediate portion of each arm
152
is connected by a bolt
2
a
to an end of a connecting rod
17
, and the other end of the connecting rod
17
is connected by another bolt
2
b
to the connecting member
141
. Thus, the vertical rod
14
is moved vertically upon pivotal movement of the handle
15
.
Although the juicer provides a force-saving effect while pressing fruit, the assembling procedure for the handle
15
, the head
13
, and the connecting rods
17
and the assembling procedure for the pressing cup
14
and the connecting rods
17
are troublesome, as bolts
2
,
2
a,
and
2
b
are used. Further, a sleeve
13
with an inner threading is required for threading engagement with the bolt
2
, and it is necessary to form a screw hole in each end of each connecting rod
17
for engagement with the bolts
2
a
and
2
b.
Additional processing and assembling are required. Further, the bolts
2
,
2
a,
and
2
b
may be disengaged from the juicer due to repeated operations of the handle
15
.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a juicer with an easy-to-assemble pivotal connection for the handle of the juicer, providing a simple structure and allowing easy assembly of the juicer.
A juicer in accordance with the present invention comprises:
a base;
a column extending upright from the base;
a head securely attached to an upper end of the column, the head including a vertical hole and a transverse hole;
a vertical rod extending vertically through the vertical hole of the head, a pressure cup being securely attached to a lower end of the vertical rod by a connecting member;
a Y-shaped handle including a main section and two arms branching from an end of the main section, each arm including a distal end having a hole aligned with the transverse hole of the head; and
a pair of connecting rods each having an upper end and a lower end aligned with the connecting member, the upper end of each connecting rod being connected to an intermediate portion of an associated one of the arms of the handle;
an axle pivotally extended through the transverse hole of the head and the holes of the handle, each of two ends of the axle including an annular groove, a first retainer being mounted in each said annular groove of the axle for preventing disengagement of the axle;
the connecting member of the pressure cup including two ears respectively extending outward from two ends thereof, each said ear including an annular groove, each said ear respectively extending through the lower end of an associated one of the connecting rods, a second retainer being mounted in said annular groove of each said ear for preventing disengagement of the connecting rod; and
a pin extended through the upper end of each said connecting rod and intermediate portion of each said arm of said handle, and a third retainer being provided for preventing disengagement of said handle.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
