Description
The invention relates to a receptacle for storing elongated
articles, particularly tools, such as twist drills, thread taps and
the like, comprising an upright square-shaped container having
blind holes on its upper side for inserting the articles, and a
pair of tray-shaped closure flaps which are supported on opposite
sides of the container, which flaps are laterally pivotable to
enclose the articles when not in use and are retained in their
closed position by closing means.
Receptacles of this type for storing drills and/or thread taps are
already known. In these known embodiments the closing flaps are
individually connected with the sides of the container (German
Utility Model No. 1,764,559, German Utility Model No. 1,895,600).
To open the receptacle, the closing flaps are laterally pivoted
until they are supported on the bearing surface of the container.
Therefore, these receptacles are relatively bulky when in the open
position, as tools can only be easily removed from the box when the
latter is in the upright position.
The problem underlying the invention is to improve conventional
boxes in such a manner that, when in the open position, the closure
flaps do not project away from the container in an obstructive
manner and that, even when the open container is tilted, tools may
be advantageously removed therefrom.
In accordance with a primary object of the present invention, this
problem is solved by providing on the container normally-closed
hingedly connected closure flaps which are operable to an open
condition for sliding displacement downwardly relative to the
container. Receptacles designed in accordance with the invention
are therefore characterized in that, when open, the receptacle has
approximately the same height as its central container which, as a
result of the slightly laterally pivoted closure flaps, is somewhat
broader on the side where the tools are inserted into the container
than on its bearing side. Therefore, even when open this receptacle
represents a handy article which may be advantageously used when
open even when the surrounding space is limited (for example,
inside a tool chest or tool bag), and the container may be tilted
also in the open position without the closure flaps preventing the
removal of tools. In a preferred embodiment, the height of the
container is substantially equal to the length of the sides of the
closure flap which are guided along oppositely lying sides of the
container.
In accordance with a further object, the container is designed so
that the closure flaps can be pivoted outwardly through a
predetermined opening angle to an open condition, this opening
angle being retained when the flaps move over their entire path of
movement on the container. The arrangement and guiding of the
closing members on the container can be effected in a variety of
ways, In any case it is advantageous to arrange the closing members
on the container so that no additional elements are required on
either the container or closing flaps to minimize expenditure and
simplify the assembly of the receptacle as far as possible. It is
therefore provided in accordance with the invention for the side
portions of the closure flaps to be designed at their lower ends as
telescopically mounted hinge members.
The opening angle of the flaps may be simply determined in this
connection by providing each of the telescopically mounted hinge
members of the sides of the closure flaps with a stop face which,
when in contact with one another, define the opening angle of the
closure flap. In this connection the automatic locking of the flaps
in their open position on the container may be simply effected if,
in accordance with another feature of the invention, the inner
sides of the closing flaps are each provided with at least one
projection which, when the flaps move relative to the container,
bears against the adjacent wall of the container to lock the
closure flaps in their open position.
In order to permit the side portions of the flaps supporting the
hinge members on the container to be guided in a particularly
technically simple manner, the inner hinge member of the
telescopically mounted hinge members on the closure flaps is
annular and slidably guided along the associated wall of the
container between webs which extend along the lateral edges of the
container. These webs therefore form lateral guide strips or bars
between which the annular hinge member engages. In this connection
the lower end position of the closure flaps on the container
located in their opening position may be simply fixed by a further
web which is moulded to the corresponding lower edge of the
container and forms a stop for the ring-shaped hinge members. In
accordance with another object, the box is also constructed so
that, if the closure flaps slide upwardly on the container, they
are automatically pivoted back again into their closed position.
This may be simply effected if in the vicinity of the upper end of
the container the guide faces, which are formed by the lateral webs
and guide the hinge members of the flaps, are upwardly and inwardly
inclined, and if the inner sides of the closure flaps supporting
the hinge members are each provided with a cylindrical extension
some distance from the hinge members, which extensions bear against
the converging guide faces when the closure flaps are moved in the
direction of the upper side of the container. In this connection
the extensions provided on the inner sides of the closure flaps are
each advantageously associated with a stop on the side walls of the
container in the area in which the extensions are located near to
the latter when the closure flaps are in the closed position, with
which stops the extensions are locked in the closed position of the
flaps. The extensions together with the stops therefore form part
of the closing means of the flaps. To ensure that the closure of
the separating joint between the closure flaps is as dustproof as
possible, a web directed towards the oppositely lying side of the
opposite closure flap is also provided on at least one side of at
least one other closing flap, which webs grip the rear of the
oppositely lying side of the opposite closure flap when the flaps
are in the closed position, thereby providing the separating joint
between the closure flaps with an inwardly directed seal.
Furthermore, the separating joint may also be closed from above in
the same manner.
In accordance with another feature of the invention, indicia
relating to technical details (particularly, diameter sizes) may be
arranged on the outer side of the front wall of the flaps
connecting the side portions, which details are coordinated with
the various tool insert openings provided on the upper face of the
container so that the position of the required tool can be rapidly
seen when using such a box. Finally, the container and the closure
flaps may be manufactured in a known manner by plastic moulded
sections to which the extensions, webs, projections and stops are
moulded in one piece.
Other objects of the invention will become apparent from a study of
the following specification when viewed in the light of the
accompanying drawing, in which:
FIG. 1 is a perspective view of a closed upright box;
FIG. 2 is an end view of the box of FIG. 1;
FIG. 3 is a perspective view of an open tilted box;
FIG. 4 is an inner view of one of the closing flaps of the box;
and
FIg. 5 is a sectional view taken along the line 5--5 of FIG. 4.
The tool box shown in FIGS. 1 to 3 comprises a rectangular
container 10 standing on its end and including an upper face 12
which contains two rows of blind holes for the insertion of drills
14. The area in which the drills project out of the container is
enclosed by two closure flaps 16, 18. Therefore, when not in use
they are protected from external influences. Moreover, the closure
flaps provide support for the drills in the box.
To remove a drill, the closure flaps are pivoted apart in the
direction of the arrows shown in FIG. 1, the flaps being pivotable
towards one another into a predetermined angular position
illustrated by the opening angle in FIG. 5. The two closure flaps
can be jointly moved downwardly along the side walls of the
container until the inner surfaces 20 of their upper front walls 21
are located adjacent the upper edges 22 of the container. In this
connection, as soon as the closure flaps are pivoted outwardly
relative to the container, they are locked in their open position,
the result of which will be described in more detail further on.
The closure flaps each include two side walls 24, 26, the height of
which is substantially equal to the height of the container. For
this reason the box, when open, has substantially the same height
as the container. In this connnection the locking of the closure
flaps on the container in their open position makes it possible to
tilt the open box, as shown in FIG. 3, without the closure flaps
preventing the removal of drills.
The closure flaps are arranged on the container in the following
manner. Their side walls 24, 26 are hinged together at their lower
ends by hinge members which positively engage in one another and
are therefore pivotable about a common axis. Whereas in this
connection an annular receiving portion 28 is moulded to one side
wall, an inwardly directed, cup-shaped cylindrical bearing portion
30 is preferably moulded to the other side wall of the same closure
flap. The bearing portion 30 of each of the adjacent side walls 24,
26 of the closure flaps engages positively in the annular receiving
portion 28 to provide the mutual pivotable arrangement of the
closure flaps. This mutual bearing also makes it possible to move
the closure flaps along the narrow sides of the container. For the
guiding of the hinge members of the closure flaps on the narrow
sides of the container, guide webs 32, 34 project along its edges
and perpendicular to the narrow sides of the container and a web 36
is provided on the bottom edge of said narrow sides. The annular
receiving portion 28 acting as a hinge member engages between these
webs so that it is guided sideways. The lower position of the
closure flaps is fixed by the web 36 which acts as a stop. The
opening angle of the two closure flaps is similarly defined by the
hinge members 28, 30 of the sides, the hinge members in positive
engagement each including stop faces 38 and 40 (FIG. 5) which bear
against one another when the closure flaps are in the open
position.
As already mentioned above, the closure flaps are locked in their
open position on the container from the moment when they are moved,
in the open position, downwardly toward the bottom of the
container. This is effected by two projections 42, 44, which are
each moulded to the inner sides of the closure flaps directly next
to their side portions, each of said projections bearing against
the outer side of the adjacent wall of the container when the
closure flaps are moved (see FIG. 5).
Furthermore, the embodiment is designed so that, when the closure
flaps are moved in the direction of the upper face 12 of the
container, they automatically pivot inwardly into their closed
position. For this purpose the lateral webs 32, 34 in the vicinity
of the upper side of the container define guide faces 46, 48 which
are inclined upwardly and inwardly. Each guide face is associated
with, for example, a cylindrical extension 50 on the inside of the
adjacent side of the closure flaps. When the closure flaps are
moved in the direction of the upper side of the container, these
cylindrical extensions come into contact with the converging guide
faces, whereupon the flaps are automatically moved towards one
another. On the sides of the container in the vicinity of the guide
faces 46, 48, the cylindrical extensions 50 are each associated
with a stop 52, for example in the form of a small raised portion,
which lock the cylindrical extensions 50 on the associated side
wall of the container when the closure flaps are in the closed
position. The parts 50, 52 therefore form a device for closing the
box.
For the tight sealing of the separating joint 54 located in the
closed position between the flaps, a web 56 projecting in the
direction of one side of oppositely lying sides of the flaps is
moulded to the other side, and these webs grip the rear of the
oppositely lying side when the closure flaps are in the closed
position. Such a web can also be provided along the inner edge 20
of the front wall 21 of the flaps.
As can be seen in FIG. 3, two rows of tool insert openings, for
example, are provided on the upper face 12 of the container. Each
of the insert openings belonging to a row of openings on the front
wall 21 of the adjacent closure flap is associated with a
corresponding size to serve as a guide to which opening is intended
for which tool diameter.
