COMPLETE SPECIFICATION.
Improved Collapsible Box.
I, Alfred ORTH of Dorfstrasse, Lomnitz, Riesengebirge, in the Empire of
Germany, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to collapsible boxes and it has for its object to enable the
capacity of the box to be varied to suit the bulk of the contents so as to prevent
their disarrangement during transport and make the box more convenient to carry
when only partially filled.
The invention consists of a box for carrying upon the back, the depth of which
can be varied, and it is shewn in the accompanying drawings of which
Figure 1 is a perspective rear view of the box with the lid removed and Figure 2
a like view of the lid.
Figure 3 shows how the stay rods are adjusted for different depths and Figure 4
shows straps and buckles for holding individual sections collapsed.
The body of the box is formed by parallel distension frames b covered with
American cloth forming bellows-like gussets c and its depth is varied to suit the
bulk of the contents by means of toggle-links d jointed to the frames b, the body
being secured at the proper depth and with the necessary rigidity by means of
adjustable diagonal stay-rods e.
The box-frame has a series of holes & corresponding to the various positions of
the stay-rods e, as indicated in dotted lines, for different depths of box, into any one
of which holes return ends of the stay-rods adjustably engage.
The lid is secured by the ends of a strap 9, passed beneath loops f on the rear of
the box, being engaged with buckles on the ends of a corresponding strap 9 passed
through loops g' on the lid.
The retaining of individual gussets in the collapsed position is provided for, -as
shewn in Figure 4, by double buckles t attached to alternate gussets to which are
buckled or not, as required, one or both ends of double-ended short straps u
attached to the intermediate sections.
Adjustable shoulder straps k (Figure 2) provided with sliding pads i are attached
to the strap g, the other ends of the shoulder straps being fastened to the lid, the
one by means of a buckle m and the other by a hook / which is connected after
the straps have been passed over the shoulders. For convenience when carrying
and lifting up and down, a pair of handles n are provided.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A collapsible box capable of being adjusted and maintained in a wholly or
partially expanded condition, whose body is composed of distension frames covered
with material and connected together by toggle links, in combination with diagonal
stay-rods or braces whereby the capacity of the box may be varied to suit the bulk
of the contents, substantially as specified.
2. In a box constituted as herein specified, the arrangement of a pair of

page_text: shoulder straps attached removably to the encircling strap and to the lid of the
box, as described.
