Definitions
- the present invention relates to a armrest/backrest support bracket for chairs, in particular office chairs.
- Support brackets for chair armrests or backrests are known, consisting of an upper part or pad on which the arm or back of the chair user rests, a vertical support and a horizontal blade for its fixing to the chair frame.
- These brackets however present the drawback of lack of flexibility and modularity. In this respect, seeing the large variety of chairs and applications, it is important that these armrest and backrest brackets can be modified in terms of their main dimensions.
- the known art often uses plastic or aluminium parts obtained by injection moulding, which by their very nature are very rigid in adapting to the individual person.
- brackets have been proposed consisting of separate vertical support elements and horizontal fixing elements welded together. This arrangement only partly solves the problems as the parts produced in this manner are in any event bulky and rigid when the parts are combined. They also present considerable aesthetic problems which can be solved only by applying coverings on the weld region and by costly cleaning operations.
- Another proposed arrangement consists of a single bent blade which performs both the bracket and support function. This arrangement however presents evident limits in terms of bulk, appearance and modularity.
- Another proposed arrangement is to fix the blade to a tubular support element by screwing it onto a bush welded inside the tubular element. This arrangement has the drawback of substantial cost due to welding and to the use of a relatively costly element such as the lathe-turned bush.
- Brackets are also known which enable the height of the arm/back support to be adjusted by the use of telescopic elements. These known brackets present however certain drawbacks and in particular:
- brackets have been proposed in which the tube slides internally via an additional guide while the outer sleeve has only an aesthetic function. Again in this case the addition of another important element leads to additional costs and does not fully solve the problem of sliding precision because of the aforesaid known problems.
- costly arrangements have to be used comprising seats obtained by rectifying machining or fixtures with movements to obtain undercuts, or open half- shells which once assembled enclose one of the telescopic elements.
- the known art presents various solutions for locking the movement of the telescopic elements of the brackets.
- Figure 1 is a perspective view of a chair provided with the bracket
- Figure 2 is an exploded perspective view of a bracket
- Figure 3 shows it in its assembled configuration
- Figures 4-6 show different connection systems for locking the blade to the tubular support
- Figure 7 is an exploded perspective view of an adjustable bracket
- Figure 8 is a cross-section therethrough
- Figure 9 is a longitudinal section therethrough
- Figure 10 shows the connection of the sleeve shoes.
- the support bracket according to the invention comprises substantially a horizontal support 2 rigid with a tubular support 4, a blade 6 with threaded hole 8 and a knob 10 provided with a threaded pin 12 and a pressing surface 13.
- a through slot 14 is provided in the tubular support 4.
- the blade 6 is inserted into the slot 14, after which the threaded pin is inserted from the support base to engage in the hole 8.
- the knob has been screwed in, its surface 13 presses against the end of the support.
- a screw 18 and cap 21 are used to achieve pressing against the tubular support and tightening of the bracket, in contrast to the embodiment of Figures 3 and 3 in which these functions are performed by the knob 10.
- the cap 20 is provided internally with a threaded nut 16 in which a screw 18 engages after passing through the (no longer threaded) hole 8 of the blade 6.
- the fixing element consists of a lever 22 with an eccentric head 24 to which there is pivoted a tie bar 26 which passes through an elongate hole 9 provided in the blade 6 and is provided at its other end with a counteracting plate 28.
- FIGS 7-9 show a height-adjustable armrest.
- Said armrest comprises a metal tubular element 30, a wall of which comprises a plurality of overlying holes 32 and two inwardly facing lugs 31.
- This tubular element is inserted into a plastic sleeve 34 rigidly fixed to the arm support 36 by screws 38.
- the lower end of the tubular element 30 is inserted into a cap 40 into which the end of the blade 6 is also inserted by the already described systems, between the tubular element 30 and the sleeve 34 there being interposed two shoes 42 of self-lubricating material.
- the shoes 42 perform various functions.
- the armrest also comprises a substantially T-shaped locking element 48.
- the vertical portion 50 presents channels 51 in which the two lugs 31 engage to limit the stroke of the telescopic elements.
- the lower end of the vertical portion 50 is provided with a tooth 52 selectively engagable in one of the holes 32 of the tubular support 30.
- This locking element 48 also has an end 54 of a horizontal portion housed in a seat 56 provided on the top of the sleeve and retained by the arm support element 36. This end 54 acts as a hinge for the lever formed by the locking element, which also comprises a spring urging the tooth 52 into engagement with the holes.
- the tooth 52 can be disengaged from the hole 32 by operating the other portion 58 of the element 48, to enable the sleeve to slide relative to the support.
- the pushbutton is positioned immediately below and to the side of the arm support element 36 and moves vertically, i.e. the same adjustment direction as the telescopic elements of the armrest.
