Abstract
A carry-on case having a base and a connected lid. A handle is pivotally carried by the lid and is shiftable between a lowered position overlying the lid and a raised position extending upwardly from the lid. The handle is extendable between a collapsed position in which the grip of the handle is next to the lid and an extended position in which the grip is substantially spaced from the lid. Wheels are carried by the base. The handle includes releasable lock pins which extend upwardly and downwardly from a cross brace forming a part of the handle and which serve to secure the handle in either of its extended or collapsed positions. When the handle is in its collapsed position, the upwardly extending lock pins are enclosed by the handle leaving the lower extending lock pins available to release the handle for its extendable movement.
Description
SUMMARY OF THE INVENTION
This invention relates to a carry-on case having an extendable and retractable handle and will have specific application to a locking device by which the handle may be secured in a fully collapsed position or released into extended positions.
The carry-on case of this invention includes a base and a connected lid. The base carries wheels and a handle is pivotally carried by the lid. The handle is shiftable relative to the lid between a lowered position overlying the lid and a raised position extending upwardly from the lid. The handle is extendable between a collapsed position in which the grip part of the handle is adjacent the lid and an extended position in which the grip part is substantially spaced from the lid and base while the handle is in its lowered position. The handle includes a releasable lock formed of upwardly and downwardly extending pin parts each accessible when the handle is in an extended position. When the handle is collapsed, the grip part covers the upwardly extending pin parts. The downwardly extending pin parts are then utilized to release the handle from its collapsed position for movement into its extended positions.
Heretofore, as shown in U.S. Pat. No. 5,368,143, the grip part of the handle when the handle is secured in its collapsed position was slightly spaced from the handle cross brace, adjacent the lid of the case. While this would enable the user of the carry-on case to carry the case by gripping the spaced but collapsed handle at its grip part, it also provided a ready means by which baggage handlers should the case be checked during airplane flights could easily throw the case during handling. Such handling was prone to damaging the case. In this invention the releasable lock for the handle has been improved so as to enable the grip part of the handle to be located snugly against the case in a locked position thus providing no ready means by which a baggage handler may use the handle grip part for locating the case.
Accordingly, it is the object of this invention to provide an improved carry-on case in which the extendable handle used to pull the case may be fully secured in a collapsed position against the case.
Other objects of this invention will become apparent upon a reading of the following description.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The description of this invention incorporates components and parts used extensively in U.S. Pat. Nos. 5,368,143 and 5,116,289, both of which are incorporated herein by reference. Case
10
includes a housing formed by a base
12
and a lid
14
both of which are connected and held together by hinges. Case
10
also includes two wheels
30
and a handle
40
that is releasably extendable, collapsible, lowerable and raiseable. Lid
14
is shiftable about its hinges from an open position to a closed position. Wheels
30
(only one shown) are positioned on opposite sides of the base and are journalled upon an axle member.
Handle
40
of the case includes two parallel side rails each of which is formed of an outer telescopic member
43
and an inner telescopic member
45
. Outer telescopic members
43
are joined at opposite corresponding ends by a cross brace
50
and are each connected to lid
14
at their opposite corresponding ends by a pivot rod. Alternatively, member
43
may be pivotally connected to the base. A hand grip
48
is connected to inner telescopic numbers
45
of handle
40
at their free ends. The inner telescopic members
45
are shiftable relative to the outer telescopic members
43
to allow handle
40
to assume the collapsed position as seen in
FIGS. 4 and 6
and the extended position as seen in
FIGS. 1 and 2
. Additionally, the handle can assume an intermediate extended position in which the hand grip
48
is secured in an intermediate carry position as seen in
FIGS. 3 and 5
adjacent lid
14
when the handle is in its lowered position.
Handle
40
is shiftable between a lowered position against the lid and a raised position extending upwardly from the lid as seen and described in U.S. Pat. Nos. 5,368,143 and 5,116,289. Handle
40
is selectively secured in its collapsed position, extended position or intermediate carrying position by means of a locking system which is housed in and carried by cross brace
50
. This locking system includes two lock rods
58
which are oppositely extending and axially aligned. The lock rods which are retained within the cross brace
50
protrude through guide holes
57
formed in the inside of the outer telescopic members
43
and aligned set of lock holes
59
in the inner telescopic members
45
. Each of the lock rods
58
can be retracted out of the lock holes
59
to permit the inner telescopic members to shift relative to the outer telescopic members and thus permit the retraction of the handle.
Lock rods
58
are normally urged outwardly into a protruding position relative to lock holes
59
by a helical spring
60
. Helical spring
60
abuts at each of its ends in compressive engagement a transverse pin
62
which is press-fitted through each lock rod
58
. Each pin
62
extends from opposite sides of cross brace
50
and through an oblong slot
53
in the brace. By squeezing the two opposite exposed end parts
61
of pins
62
on either side of cross brace
50
, helical spring
60
is compressed and lock rods
58
are drawn together to withdraw the outer ends of the lock rods from the lock holes
59
in the inner telescopic members
45
to free handle
40
for its retractive movement.
Inner telescopic members
45
have two other sets
63
and
65
of aligned lock holes. Lock holes
63
in the inner telescopic members
45
are adjacent the outer most ends of the members and configured to receive lock rods
58
when the handle is in its collapsed position. Lock holes
65
are slightly spaced from lock holes
63
and when receiving the ends of lock rods
58
serve to secure the handle in an extended carrying position slightly spaced from the case base and lid so as to enable the hand grip
48
to be utilized as a carrying handle by the user of the case. In either the extended position or the carrying position of the handle, both protruding end parts
61
of pins
62
are accessible to the user of the case and thus either pair of opposed pin end parts may be used to release the lock rods
58
to allow shiftable movement of the handle. When handle
40
is secured in its collapsed position with lock rods
58
protruding into lock holes
63
in inner telescopic members
45
, the handle is fitted essentially against lid
14
with the hand grip
48
covering the end parts
61
of pins
62
which protrude from the cross brace
50
toward the hand grip. To free the handle from its collapsed position, only the oppositely extending end parts
61
of pins
62
are accessible to the user within recess
15
in lid
14
. A foam member
70
which is carried by hand grip
48
provides not only a gripping surface for the user but also an absorbent for the handle when it is placed in its collapsed position. In this position, member
70
is squeezed or compressed between hand grip
48
and cross brace
50
so as to provide shock absorbing movement for the handle when it is moved into its collapsed position as well as tension between the hand grip and cross brace, thus reducing any interplay between lock rods
58
and inner telescopic members
45
at lock holes
63
.
Handle
40
is secured in its lowered position against lid
14
by releasable lock pins
51
carried by cross brace
50
. A spring
54
causes each lock pin
51
to be biased over a strike plate
56
attached to lid
14
and into a recess in the lid. To free handle
40
, the lock pins
51
need only be pulled outwardly which compresses springs
54
and withdraws the pins from the lid.
The above invention is not to be limited to the details as described but rather may be modified within the scope of the appended claims.
