Abstract
Description
- The present invention relates to chairs, and in particular to office chairs.
- In office chairs the back-rest is known to be connected to the seat by a connection device by which the back-rest is supported.
- These chairs are of considerable bulk and can hence, when not in use, represent in an office a somewhat annoying hindrance, in addition to requiring the availability of adequate storage space prior to sale, the availability of adequate space in the transport vehicle which delivers the chair to the client, and the provision of suitable packaging containers or wrappings.
- The object of the present invention is to obviate the aforesaid drawbacks by providing a chair, in particular an office chair, which when not in use or when having to be stored or otherwise placed out of service, has a decidedly smaller bulk and consequently requires packaging containers or wrappings of smaller size than similar known chairs.
- This object is attained by the chair of the present invention, characterised in that the connection device between the back-rest and seat comprises an articulated joint which enables the back-rest to be folded onto the seat.
- In this manner, when not in use, the chair can be made to assume a configuration having an overall size considerably less than that of the chair during use. In particular, when in its reduced-size configuration, the chair can be inserted under a desk, so that in practice the chair no longer exists in terms of the spatial utilization of the room in which the desk under which the chair is inserted is located.
- The invention will be more apparent from the following description of one embodiment thereof given by way of example. In the said description reference is made to the accompanying drawings, in which:
- Figure 1 is a rear perspective view of the back-rest/seat connection device of an office chair, in its normal utilization position;

- Figure 7 is a cross-section therethrough taken on the line 7-7 of Figure 4;
- Figure 8 is similar to Figure 7 but with the articulated joint shown in the condition in which the back-rest has been folded down onto the seat;
- Figure 9 is an elevation of the upper front part of the articulated joint, seen from the front;

-
- The
connection device 10 of Figures 1 and 2 enables the back-rest of an office chair (such a chair could however also have other uses) to be connected to the relative seat. Specifically, thedevice 10 presents alower arm 12 which enables it to be connected (for example by screws) to the lower face of the chair seat (not shown). - The
device 10 also presents an upperly extendingupper arm 14 to which the chair back-rest is fixed (for example by screws). - The two
arms joint 16 which, as can be seen from Figures 5, 6, 7 and 8, enables theupper arm 14 of thedevice 10 to be rotated from its position shown in Figures 1 and 2 (chair utilization position), corresponding to the condition of the articulated joint shown in Figures 5 and 7, into its folded position shown for simplicity only in Figure 6 but in any event also easily deducible from the condition of the articulatedjoint 16 shown in Figure 8. - Before proceeding with the description, it should be noted that the expressions "front" or "facing forward" referred to a part of the articulated
joint 16 means that that part is facing or is located close to the person seated on the chair, and "rear" or "facing rearward" means that the part is facing in the opposite direction or is located far from said person. - The articulated
joint 16 is composed of various parts and specifically a frontupper part 18, shown alone in Figures 9-14, a rearupper part 20, shown alone in Figures 15-20, a frontlower part 22, shown alone in Figures 27-32, a rearlower part 24, shown alone in Figures 21-26, and apin 26, shown alone in Figures 33-37. All these pieces are assembled in this specific case bysocket head screws 28, as shown in Figures 3-8. - It should be noted that the lower end of the
upper arm 14 is inserted into thelongitudinal slot 30 provided in thepin 26, this latter presenting in the vicinity of each of its two ends a radially projectingpeg 32. As can be seen in Figures 7 and 8, the twopegs 32 act as limit stops for the folding of the chair back-rest, thepegs 32 coming to rest against a step provided in the lowerrear part 24 of the articulatedjoint 16. A limit stop is likewise provided to maintain the back-rest in the chair utilization position, and is in the form of astep 34 provided in thelower front part 22 of the articulatedjoint 16, to interfere with astep 36 provided in theupper front part 18 of the articulated joint. - As will be apparent from the figures, the
connection device 10 is extremely simple and rapid to mount.
