Device for Connecting Chairs in a Row
The invention enables distribution of a series of chairs in row alignment, preventing undesired shifting and movement thereof, being especially intended for chairs having a bottom frame disposed underneath the seat, said frame having at least one tubular profile whereupon the seat rests; said device standing out for comprising a female part and a male part associated to the tubular profile of the chair, destined for being solidarily connected to other male and female parts, respectively, of chairs disposed in adjacent lateral positions, and where the female and male parts comprise pivoting means which allow extraction and retraction of these in a fast and simple manner, depending on whether or not arrangement of chairs in row alignment is required.
The present invention relates to the field of furniture and, more specifically, to chairs and their accessories.
The main object of the present invention is a device specially adapted for joining adjacent chairs, forming a straight row without misadjustments, thereby avoiding undesired movements and noises from the chairs.
BACKGROUND OF THE INVENTIONCurrently, different types of furniture (chairs, seats or similar) susceptible of being successively joined together two by two to form modular units are known in the state of the art.
These currently known solutions require a specific configuration of their constituent elements; for example, in cinemas, a row of seats is generally mounted on a common bar with its own bearings. Other technical solutions require the use of units formed from parts of high structural complexity, which hampers assembly and disassembly thereof to a large degree, as well as considerably raising manufacturing and production costs.
DESCRIPTION OF THE INVENTIONThe present invention resolves the aforementioned drawbacks by providing a device for joining chairs whereby a group of chairs can be quickly and easily distributed in row alignment, forming a straight row without misadjustments and preventing undesired shifting and movement of the chairs caused by the user's constant action of standing up and sitting down.
The device for joining chairs object of the invention is of the type comprising a female part and a male part destined for joining and solidarily interlocking with other male and female parts, respectively, of chairs disposed in adjacent lateral positions. More specifically, the device described herein is especially intended for chairs having a bottom frame disposed underneath the seat, said frame having at least one tubular profile whereupon said seat rests.
The device of the invention stands out mainly because its female and male parts comprise folding means, in such a manner that it is possible to extract and retract these in a fast and simple manner, depending on whether or not arrangement of chairs in row alignment is required, remaining totally hidden underneath the chair if not required.
The female part of the present invention comprises a first fixing body having a recess dimensionally adapted for adjusting to the tubular profile of the chair frame; and a locking element, preferably T-shaped, which is associated to the fixing body and defines an enclosed space, having diverging projections on its distal end.
For its part, the male part comprises a second fixing body also having a recess adapted for adjusting to the tubular profile of the chair; and a hooking element associated to the second fixing body, having sharp vertical projections on its distal end destined for being introduced into the projections of the female part, stopping against these and preventing involuntary unhooking and release thereof.
Preferably, the fixing bodies of the female and male parts are manufactured from plastic material, while the locking and hooking elements are preferably metallic.
In order to complete the description that is being made and with the object of helping to better understand the characteristics of the invention, in accordance with a preferred example of practical embodiment thereof, accompanying said description as an integral part thereof, is a set of drawings wherein the following has been represented in an illustrative and non-limiting manner:
In accordance with a preferred embodiment shown in
The device for joining chairs (1) object of the invention stands out basically for comprising folding means (30) which allow the female and male parts (10, 20) to be extracted and retracted in a fast and simple manner.
Further,
a first fixing body (11) having a recess (12) dimensionally adapted for adjusting in the tubular profile (4) of the chair (1) of the frame (2); and
a locking element (13) associated to the first fixing body (11), which defines a T-shaped enclosed space, having two diverging projections (14) on its distal end by way of a fork joined by one of their sides.
For its part,
a second fixing body (21) also having a recess (22) dimensionally adapted for adjusting to the tubular profile (4) of the chair (1) frame (2), and
a hooking element (23) associated to the second fixing body (21), having a pair of tilted sections (25), shown in
As can be observed in
In the case of the female part (10), two side sections (15) project from the fixing body (22) which taper slightly towards each other and end in two elongated parallel sections (16), shown in
In accordance with another preferred embodiment of the invention, not represented herein, both the locking element (13) and the hooking element (23) additionally comprise a rod on their proximal end which articulates on the fixing parts (11, 21), respectively, for folding thereof. As can be observed in said
Finally,
Claims
1-7. (canceled)
8. A device for connecting chairs in row alignment,
- for chairs having: a seat; a bottom frame disposed underneath the seat, and at least one tubular profile, comprised in the bottom frame, and whereupon the seat rests,
- wherein the device comprises: a female part; and a male part,
- both the female part and the male part being connectable to the tubular profile of the chair, and destined for being solidarily connected to other male and female parts, respectively, of chairs disposed in adjacent lateral positions,
- characterised in that the female and male parts comprise pivoting means for pivoting with respect to the tubular profiles, for allowing extraction and deployment thereof, depending on whether or not arrangement of chairs in row alignment is required.
9. The device of claim 8, wherein the female part comprises:
- a first fixing body having a recess dimensionally adapted for adjusting to the tubular profile, and
- a locking element, associated to the first fixing body, and defining an enclosed space, and having diverging projections on a distal end thereof.
10. The device of claim 8, wherein the male part comprises:
- a second fixing body, having a recess dimensionally adapted for adjusting to the tubular profile,
- a hooking element associated to the second fixing body,
- a pair of tilted sections located on a distal end of the hooking element,
- vertical projections projecting from the tilted sections, and
- a horizontal intermediate section project, for connecting together the vertical projections, wherein the vertical projections are destined for being introduced into the diverging projections of the female part of the adjacent chair, abutting against these and preventing involuntary unhooking thereof.
