In Czechoslovakia March. 15, 1937
3 Claims.
This invention relates to luggage in general,
and especially to luggage adjustable to varying
receiving capacities, similar to my pending appli
cation Ser. No. 86,939, ?led June 24th, 1936, now
Patent No. 2,097,476, dated May 4, 1937, of which
the present application is a continuation in part;
The prime object of this invention is to provide
a relatively simple, but effective, expansible con
tainer, which, irrespective of its size, shape or
10 particular purpose, will be readily adjustable to
any desired capacity, within its range, and will
be dustproof at any adjusted, or its normal, col
lapsed position.
Another important object of this invention is to
provide in an adjustable container of this kind
positive combination means for guiding, adjust
ing and automatically locking and holding at de
sired positions the several adjustable parts of the
container, and which means are provided with
20 hand-operative instrumentalities for rendering
the locking and holding feature of said means in
e?’ective, when so desired.
Another object of my invention is to provide
an adjustable container of the telescoping type,
25 wherein the outer member consists of two per
manently, but operatively united parts, one of
which forms a sealing cover for the other part,
and wherein the inner telescoping member is
provided with a peripheral, outwardly project
ing bottom sealing ?ange which extends into the
path of operation of, and forms a stop for the
bottom edge of the outer member.
By the term “container” it is to be understood
that I mean any kind of luggage, including hand
bags, traveling bags, hat boxes, trunks, knap
sacks, and other types of containers which may
be made advantageously adjustable and dust
proof in the manner hereinafter explained.
The foregoing and still further objects of my
~10 invention will become better understood from the
following description, in connection with the ac
companying drawing, which in a more or less
diagrammatical sense illustrate the presently pre
ferred embodiments of my disclosure, and in

attached to the two telescoping members of the
Referring now speci?cally to Figs. 4 and 5, nu
meral l0 denotes the outer telescoping member,
which is composed of a relatively high lower part
and a relatively short upper part i l, in the form
of a cover, which is permanently associated with
the lower part by means of hinge 12. The upper
portion of the lower part is preferably thickened
to form a rim 13. Its upper edge is recessed at
M to form a dustproof, sealing seat for cover II
when the latter is closed and locked. Rim i3 is
also recessed at iii to a depth approximately equal
to the thickness of the inner telescoping member
[6. This member is provided with a peripheral
?ange l1, which projects outwards into the path
of travel of outer member in, and serves as stop
and seal for the latter’s bottom edge.
Both members are interconnected with a con
tinuous lining l8, which is secured to their inner
faces. The outer end of the lining is ?xedly at
tached to the outer member, at I9, while the
major part of the lining preferably extends over
the entire inner surface of the inner telescop
ing member, and is free from the upper edge of
the latter to its outer attached end at [9. While
the members are at their normal, collapsed posi
tion,-shown in Fig. 4, the free part of the lining
forms a spacer or ?ller between the members, and
outer attached end I9 of the lining is substantial
ly below the upper edge of the inner telescoping
member. When the device is in its fully extend
ed position, as in Fig. 5, the free portion of the
lining forms a dust-proof connection between the
two members. ‘i
For the purpose of facilitating a ready adjust
ment of the container to any desired depth, I
preferably employ especially adapted means, il
lustrated in Figs. 6 and 7, wherein numeral 2
denotes a guide bar with an off-set upper end 2!,
which latter is preferably ?xedly attached to the 4
stout portion or rim l3 of the outer telescoping
member. The lower, free portion of the bar is
provided with perforations 22, and is slidably
held in a channel formation 23.
The latter is
?xedly associated with the inner telescoping 50
Secured to the raised portion of channel 23
is a spring leaf 24, the free end of which is pref
erably bent outwards at 25. Extending from the
face of the leaf adjacent to the channel, a pin 55
20. At the upper end of the channel structure
are provided bearings 28, in which is mounted
crank-like lever 29, terminating in a hand-oper
able extension 30. Lever 29 is designed for ele
ing into the path of operation of, and serving as
end stop for said one member, a dustproo?ng
lining secured to the inner faces of said members,
and being so arranged that when said members
are in their normal, fully internested position,
part of the lining forms a spacer and ?ller be
vating the free end of leaf 24 to a position in
dicated in broken lines in Fig. '7, at which pin
the inner face of the outer member, combination
26, passing through a guide~aperture 21’ in the
channel, cooperates with perforations 22 of bar
26 disengages perforations 22 of bar 20, and be
10 comes free of the latter. By moving extension 30
from its full-line position of Fig. 6, in the direc
tion away from the channel, until lever 29 con
tacts with pin 26, the outward, bar-releasing
position of the pin is reached.‘
While lever 29 is in its normal downward posi-'
tion, pin 26 is intended to automatically snap
into any one of the perforations 22, while “rid
ing” over the unperforated portions of bar 2a.
Lip 25 of leaf 24 serves for temporarily lifting
pin 26 out of engagement with perforations 22.
The positioning of lever 29 to a point whereby
pin 26 is permanently freed from contact with
bar 20, becomes advantageous when it is de
sired to either fully extend or fully collapse the
container, whereupon lever 29 is returned to its
normal, full-line position.
In constructing my telescoping containers, I
prefer to employ several of my combination guide
and adjusting means. When a container is round,
such as a hat box, only three such means are re
quired. For large collapsible trunks, four to six
guides should be used. However, for small trav
eling bags, even two guides are suf?cient.
The typical structures of telescoping contain
ers illustrated in Figs. 4 and 5, may be em
ployed for any type of luggage, irrespective of
shape or size. Similarly, the combination guide,
adjusting and snap-in holding means, as shown
tween the outer face of the inner member and
guide and adjusting means associated with both
members for automatically locking them at d.
sired positions relative to one another, said means
having an instrumentality for rendering its lock
ing feature inoperative when so desired.
2. In a container, two telescoping members, the
outer member having a closure operatively and 15
permanently associated therewith, the inner
member having a peripheral bottom flange form
ing a stop and seal for said outer member, a
lining ?xedly secured to the inner faces of both
members in such a manner that when the mem
bers are in their normal, completely internested
position, the edge of the lining secured to the
outer member will be substantially below the
upper edge of the inner member, and combina
tion guide and adjusting means secured to both 25
members and including means for automatically
locking the members at any desired position rel
ative to one another, and other means cooperat
ing with said locking means for rendering the
latter inoperative, when desired.
3. In a container, two telescoping members,
the outer member having its upper edge recessed,
a closure hingedly associated with said outer
member and engaging, when in closed position,
the recessed edge of said outer member so as 35
to form a seal for the latter, a dustproo?ng lin
ing peripherally connecting. both members at
their inner faces and being so arranged that its
in Figs. 6 and 7, are applicable to any type of end, attached to the outer member, is disposed
substantially below the upper edge of the inner 40.
