Claim. 7
It‘ is known that persons who want to make a
picnic make use of folding tables on the one hand,
and on the other hand of suitable cases or boxes
which may even be combined with the tables, but
UK which have the disadvantage that they can be
unfolded so as to be set as tables only after the
articles normally contained in the case or box
have been removed therefrom. This involves a
loss of time and even a risk of injury of said
10 articles.
On the other hand, it is also known that the
work of persons having to check up certain appa
ratus or circuits in shops or factories is generally
awkward, because these persons often do not ?nd
any place where they could put their measure
ment apparatus, which they carry in a case which
is both cumbersome and heavy.~
The object of the present invention is to pro
vide a case or box for carrying objects, adapted
20 to constitute a rolling table permitting the easy
use of the tools or apparatus, or the show of the
goods carried in said case or box.
This case is constituted by a body forming a
receptacle, a lid forming at the same time the
25 upper part of the table, four jointed feet hidden
in the case when the latter is closed but adapted
to support the lid when the table is unfolded, and
sets of wheels or rollers carried by the feet and
brought into active position only when said feet
30 are pivoted so that the case is transformed into a
c-a C.l
In a particular embodiment of the invention
these feet or legs are connected by pairs by two
cross members, and they are ?tted, at their lower
ends, with rollers or shoes which permit of easily
moving the table. These legs are adapted to pivot
through an angle of 90° about two horizontal
spindles rigidly ?xed to the body of the case. In
one of their extreme positions, these legs are fully
40 enclosed in the case, owing to the special ar
rangement of the parts, which enables a pair of
legs and their cross member to fit between the
two other legs and under the cross member cor
responding thereto. In the other extreme posi
45 tion, these legs are disposed vertically, being then
rigidly maintained by means of a latch or any
other ?xation means. The movement which
corresponds to the rising of the upper ends of the
legs, causes their lower ends to project from the
50 base of the case, which is thus lifted above the
The lid is ?xed to the longer of the two cross
members, through hinges permitting a ‘rotation
through an angle of 270°. When the legs have
been ?xed in their vertical position, the lid is piv
(01. 190-11)
oted about its hinge so as to be brought into hor
izontal position, the upper face ‘being then the
under face of the lid when the latter is applied
against the case in the closed position.
The end of the lid opposed to the hinge lies
upon the other cross-member, to which it is
rigidly ?xed by means of screws or any other
means ensuring the rigidity of the whole.
These and other features of the present inven
tion will result from the following detailed de
scription of a speci?c embodiment thereof.
A preferred embodiment of the present inven
tion will be hereinafter described, with reference
to the accompanying drawing, given merely by
way of example, and in which:
Fig. 1 is a perspective view of a case accord
ing to the invention, shown in the unfolded posi
tion, in which it acts as a table;
Fig. 2 is a sectional view of the case in the
folded position;
Fig. 3 is a sectional view on the line III-III of
Fig. 1.
The body I of the case, made of any suitable
material, is ?tted with two horizontal spindles 2
about which are pivoted the legs 3 of the table.
Said legs are so shaped, as shown by Fig. 3, that
they can pivot in the direction of arrows F with
out being interfered with by the ends 4 of the
Between partitions 5 extends the space 6
for the articles to be carried by the case.
In order to ensure the rigidity of the whole
when the case is used as a table, legs 3a and 3b are
connected together by cross-members Illa and
mo. In the closed position, cross members Illa
and 10b bear upon the chamfered portions Ha 35
and llb provided in partitions 5, at the ends
At the lower ends of legs 3a, 31), close to their
pivots 2, there are ?tted rollers or shoes l2 ow
ing to which the case, once transformed into a 40
table, can be displaced without difficulty.
In order to keep legs 3a, 3b in vertical posi
tion, when the case is used as a table, I provide
hooks l3.
Finally, the case is ?tted with holders l4 per
mitting to carry it easily.
This device will operate in the following man
The articles to be carried being placed in the
free space 6, it su?ices to grasp lid 9 with the
hand, and to pull it upwardly, whereby legs 3a
are caused to pivot about their spindle 2. When
the legs 3a have been brought into the position
shown by Fig. 1, the lid 9 is pivoted about its
hinge 8, in a direction opposed to that in which 55.
legs 30; have been precedingly turned. It then
su?ices to pivot legs 31:) about their spindle 2, so
that they can support the other end of the lid,
opposed to that hinged at 8 to legs 3a.
The objects carried in space 6 can then be
a rolling table, comprising a rigid body portion
and a movable top portion, four lever arms nor
mally hidden within the case, each located at
a corner of the case and each pivotally connected
removed so as to be put on the table.
It should be noted that all the movable ele
adjacent one end to one of the opposite lateral
walls of the case for movement from a hidden
position extending above the top of the case,
ments of the case are pivoted and kept in either
openings at the bottom of the case, the said
of their two positions without requiring assem~
10 bling members the absence of which might im
pair the strength of the whole.
pivots being located so that said ends of said
lever arms will project through the bottom of
In a general manner, while I have, in the above
description, disclosed what I deem to be practi
cal and e?ioient embodiments of the present in
15 vention, it should be well understood that I do
not wish to be limited thereto as there might
be changes made in the arrangement, disposition
and form of the parts without departing from the
principle of the present invention as compre
20 hended within the, scope of the accompanying
What I claim is:
A portable case adapted to be transformed into
the case in said latter position, transverse spac
ing bars connecting the other ends of the oppo
site lever arms at each end of the case, a hinged
connection provided between one edge of the
movable top portion and one of said spacing bars, 15
rollers normally hidden within the case mounted
upon the lower portion of said levers, said rollers
upon movement of the levers to extended posi
tion automatically lifting the same above the
?oor level.
