[0001] The present invention relates to a chair with means for constituting a row of chairs.
[0002] As is known, chairs provided with elements which allow to join two or more chairs
so as to form a row are already commercially available.
[0003] In known solutions, the connection is provided typically by interlocking two fixed
or retractable hooks, which are arranged on the sides of the chair and in many cases
form a lateral protrusion of the chair even when the chair is used individually.
[0004] Other known solutions use detachable plates which are structurally very complicated
and accordingly affect significantly the cost of the finished product.
[0005] The aim of the invention is to solve the problems described above by providing a
chair with means for constituting a row of chairs which allows to have a connecting
device constituted in practice by a single element which can be easily actuated manually.
[0006] Within this aim, an object of the invention is to provide a chair in which the connection
device, in the inactive condition, does not cause any kind of hindrance and in practice
is not visible.
[0007] Another object of the present invention is to provide a chair which thanks to its
particular constructive characteristics is capable of giving the greatest assurances
of reliability and safety in use.
[0008] Still another object of the present invention is to provide a chair with means for
constituting a row of chairs which can be obtained easily starting from commonly commercially
available elements and materials and is also competitive from a merely economical
standpoint.
[0009] This aim and these and other objects, which will become better apparent hereinafter,
are achieved by a chair with means for constituting a row of chairs, according to
the invention, comprising a supporting framework which supports, at a region below
the seat, a device for the detachable connection of chairs arranged side-by-side,
characterized in that said device for detachable connection comprises a frame connected
to supporting blocks which can be fixed to said supporting framework and can be mated
detachably and selectively to engagement blocks which can be fixed to said framework
in order to assume an inactive position, in which said engagement blocks are arranged
on the same chair provided with said supporting blocks, and an active position, in
which said engagement blocks are provided on a chair which is laterally adjacent to
the chair that supports said frame.
[0010] Further characteristics and advantages of the present invention will become better
apparent from the description of a preferred but not exclusive embodiment of a chair
with means for constituting a row of chairs, illustrated by way of non-limiting example
in the accompanying drawings, wherein:
Figure 1 is a schematic perspective view of a plurality of chairs arranged side-by-side
and joined so as to form a row;
Figure 2 is a front elevation view of a row of chairs;
Figure 3 is a side view of a chair;
Figure 4 is a bottom plan view of a chair;
Figure 5 is a bottom view of a plurality of chairs arranged side-by-side so as to
constitute a row;
Figure 6 is a schematic perspective view, taken from the lower part, of the device
for detachably connecting chairs arranged side-by-side;
Figure 7 is a sectional view, taken along the line VII-VII of Figure 3;
Figure 8 is an enlarged-scale sectional view of the detail of the supporting blocks;
Figure 9 is an enlarged-scale sectional view of the detail of the engagement blocks.
[0011] With reference to the figures, the chair with means for constituting a row of chairs,
according to the invention, generally designated by the reference numeral 1, comprises
a supporting framework, designated by the reference numeral 2, which can be of any
type and can have any shape so as to provide connection to a seat 3 which also can
assume any configuration or structure.
[0012] A device for the detachable connection of chairs arranged side-by-side is provided
below the region affected by the seat 3 and has the peculiarity that it comprises
a frame 10, which is preferably made of metal rod and is substantially U-shaped, the
ends of its free arms 11 being bent so as to enter supporting blocks 12, preferably
made of plastics, which are rigidly connected to the framework 2.
[0013] It is optionally possible to provide a fixing bar 14 for connection to the framework
or it is also possible to connect the blocks 12 directly to the seat or to the framework.
[0014] The connection between the frame 10 and the supporting elements allows such frame
to rotate about an axis which is substantially parallel to the plane defined by the
seat.
[0015] The frame 10, in the central portion which lies opposite the pivoting side, advantageously
defines a bend 15, which provides in practice a grip element for actuating the frame.
[0016] There are also engagement blocks 20, which are also advantageously made of plastics
and can be fixed to the framework 2 directly or by means of the bar 14.
[0017] The blocks 20 define at least one insertion seat 21, which in practice is delimited
by a hook-shaped portion 22 on the free end, which allows to provide the snap insertion
of the frame 10 at the side that lies opposite the side for pivoting to the blocks
12, in a region which is laterally adjacent to the bend 15.
[0018] The arrangement provided above allows to mate the frame 10, in inactive conditions,
on the engagement blocks 20 provided on the same chair which is provided with the
supporting blocks, so that the frame 10 is positioned below the chair and does not
protrude in any way laterally and substantially is not even visible.
[0019] In order to obtain the row of chairs by arranging side-by-side a plurality of chairs,
it is sufficient to free the frame 10 from the engagement blocks provided on the chair
and, by turning it by using the axis of rotation, which in practice is defined by
the folded portions 11, to interlock the side of the frame that lies opposite the
side for pivoting within engagement blocks 20 provided in a laterally adjacent chair,
thus achieving accordingly the engagement of the chair and its correct arrangement
in a laterally adjacent position, with the possibility to provide a row of chairs.
[0020] With this arrangement it is therefore possible to arrange side-by-side a plurality
of chairs, by using interconnection means which are particularly simple from a structural
standpoint, since they can be obtained by means of plastic blocks which are particularly
easy to manufacture and by means of a simple bent iron rod.
[0021] It should be added to the above that it is preferably convenient to provide the last
chair of the row without the frame, so as to avoid the frame hanging loose.
[0022] From what has been described above it is therefore evident that the invention achieves
the proposed aim and objects, and in particular the fact is stressed that a chair
is provided in which the device for the detachable connection of a plurality of chairs
is obtained by way of means which are particularly simple from a structural standpoint
and are particularly easy to actuate.
[0023] The invention thus conceived is susceptible of numerous modifications and variations,
all of which are within the scope of the appended claims.
[0024] All the details may further be replaced with other technically equivalent elements.
[0025] In practice, the materials used, as well as the contingent shapes and dimensions,
may be any according to requirements.
