Abstract
A rocking chair mechanism (I) comprising a rotating rocker (2), a stationary support (3), a springing means (4), an upper assembly (5), and a lower assembly (6), such that rotating (rocker 2) and springing means (4) are laterally integrated. Rocking chair mechanism (1) is an independent unit that can be manufactured separately then supplied to rocking chair manufacturers for incorporation into rocking chairs such as rocking chair (7). Alternatively, a rocking chair such as rocking chair (7) can be constructed using a laterally integrated rocking chair mechanism within each arm.
Description
- The present invention relates to a laterally-slim, arm-incorporated rocking chair mechanism.
- Spring-assisted rocking chairs are well-known, in which a seat (that normally consists of a supporting surface on which the sitter sits, a back rest and two arms, collectively referred to as “seat”) having rotating bearers (commonly known as “rockers”) is unstably mounted on a stationary base, using springing means to achieve stability and to sustain the traditional oscillating rocking chair movement, such as the rocking chair illustrated in
FIG. 1 and the rocking chair mechanism illustrated inFIG. 2 . - In EP 1211967 the rotating rockers are raised a long way from floor level and located within the arms of the chair, which provides a solution for the safety hazard of fingers or toes being pinched by the exposed rotating rocker and stationary base, and also provides the design advantage of being able to design open-base rocking chairs—which have a more modern look—as opposed to boxed or skirted chairs.
- However, traditionally the springing means are connected to the side of the rotating rocker, as illustrated in
FIG. 2 , in which case the cubic space of the rotating rocker is laterally attached to the cubic space of the springing means. Normally, this is not a problem but if the rotating rocker and the springing means are located within the arm of the chair—side by side—the width of each arm would have to be wide enough to incorporate the width of the rotating rocker and the width of the springing means, which adds up to the overall width of the chair. Although the issue of the overall width of the chair can be aesthetically designed around with relative ease, there are other impractical inconveniences, for example the chair taking up more space during transportation than otherwise, which adds to the cost, or the chair being relatively difficult to carry through narrow doorways. - An object of the present invention is to provide a solution as claimed in

FIG. 6 is a diagrammatic perspective of arocking chair 7, that incorporates two laterally integrated rocking chair mechanisms 1 (one mechanism within each of the two arms) by connecting eachupper assembly 5 toseat 7 a and connecting eachlower assembly 6 tostationary base 7 b, so thatseat 7 a can move (along withupper assembly 5 and rotating rocker 2) in relation tostationary base 7 b (andlower assembly 6 and stationary support 3). As illustrated, the chair has an open-base (as opposed to boxed or skirted chairs) and the bottoms of thearms 7 c are noticeably above floor level. -
FIGS. 7 to 20 are side views of different other ways of constructing the invention. - In
FIG. 7 the springing means consist ofcompression spring 4 a andextension spring 4 b. -
FIG. 8 is an illustration of a mechanism similar to the mechanism inFIG. 7 , except that the axis of each spring is angled to accommodate the direction of movement. -
FIG. 9 is an illustration of a mechanism similar to the mechanism inFIG. 3 , except thatstationary support 3 is not curved but is a flat surface that is shown here as being sloped downwards (towards the back rest). -

FIG. 11 is an illustration of a mechanism similar to the mechanism inFIG. 3 , except that the springing means consists of twocompression springs 4 a. -
FIG. 12 is an illustration of a mechanism similar to the mechanism inFIG. 7 , except thatcompression spring 4 a is not connected toupper assembly 5, and therefore only comes into action as a result of the weight of the sitter. -
FIG. 13 is an illustration of a mechanism similar to the mechanisms inFIGS. 7 and 12 , except that springing means 4 a is a nest of two springs, the lower of the two of which only comes into action as a result of the weight of the sitter being above a given weight, to be determined by the designer. -
FIG. 14 is an illustration of a mechanism similar to the mechanism inFIG. 3 , except that the curve of rotatingrocker 2 is roughly a quarter of a circle, whose diameter is relatively small. -
FIG. 15 is an illustration of a mechanism similar to the mechanisms inFIGS. 3 and 14 , except that the curve of rotatingrocker 2 is roughly half a circle, whose diameter is relatively small. It should be noted that the active part of the surface of rotatingrocker 2 is only roughly a quarter of a circle (more or less the same as inFIG. 14 ). -
FIG. 16 is an illustration of a mechanism similar to the mechanisms inFIGS. 3 , 14 and 15, except that rotatingrocker 2 is shown as a complete circle—which can be a wheel or a roller—whose diameter is relatively small. Two things need to be highlighted here. First, the active part of the surface of rotatingrocker 2 is only roughly a quarter of a circle (more or less the same as inFIGS. 14 and 15 ). Second, the circumference of the wheel or the roller is fixed in relation to its centre and as such the wheel or the roller is not used as a wheel or a roller (whose circumference rotates around its centre) but only as a curved surface. The primary reason for considering the use of a wheel or a roller in such a manner is simply as a convenient way of reducing manufacturing costs by using off-the-shelf mass-produced wheels or rollers instead of manufacturing rotatingrocker 2 as a special component. - In
FIG. 17 rotatingrocker 2 is shown as a circle, which can be a wheel or a roller (similar toFIG. 16 ), except that here the circumference of the wheel or the roller is free to rotate around its centre, and therefore the wheel or the roller is used as a wheel or a roller that moves on the curved surface ofstationary support 3. The illustration also shows wheel/roller bracket 8,compression spring 4 a andextension spring 4 b. -
FIG. 18 is an illustration of a mechanism similar to the mechanism inFIG. 17 , except that bothcompression spring 4 a andextension spring 4 b are fixed in horizontal positions. The illustration also showsblock 9 a which is connected toupper assembly 5 andblock 9 b, which is connected tolower assembly 6, both of which blocks provide a firm forward stop when the sitter leans forward to vacate the chair. - In both the mechanisms that are illustrated in
FIGS. 17 and 18 , the rotation of the seat is achieved by the movement of the wheel or the roller in relation tostationary support 3, which in this case must be curved as illustrated, otherwise the movement of the seat will be linear and therefore make the chair a gliding chair rather than a rocking chair, whose movement is—by definition—rotational. Given that the rotation of the seat in this case is created—solely—by the curve ofstationary support 3, it is also possible to have more than one wheel or roller acting—collectively—as rotatingrocker 2 and moving in relation tostationary support 3. - In
FIG. 19 rotatingrocker 2 is the outer circumference of a ball or roller bearing andstationary support 3 is the inner circumference of the same ball or roller bearing. Also illustrated arehousing 10 that connects rotatingrocker 2 toupper assembly 5,bracket 11 that connectsstationary support 3 tolower assembly 6,compression spring 4 a andextension spring 4 b. - Alternatively, when a ball or a roller bearing is used the designer will have the option of using the inner circumference of the bearing as rotating
rocker 2 and consequently connect it toupper assembly 5 and the outer circumference of the bearing asstationary support 3 and consequently connect it tolower assembly 6. - Although it is traditional for the rotating rocker to be curved at both ends—such as rotating rocker A in FIG. 2—this is not actually necessary and may even be perceived as inconvenient by some chair users. The reason is that the rocking chair movement is mainly required when the sitter is sitting back in the seat i.e. the backward and forward rocking chair movement is mainly required—and is enjoyed most—between a point where the sitter is sitting substantially upright or slightly reclined and another point further back. However, when the sitter starts to lean forward to vacate the chair it may be inconvenient for her/him if the rocking chair movement is also accessible.
- This is why
FIGS. 3 , 5 and 7-19 illustrate a mechanism that provides a restricted range for the rocking chair movement and a firm forward stop when the sitter leans forward to vacate the chair. Such a firm forward stop is achieved in one or more way. Having extension springing means in front of the movement means that when the sitter leans forward to vacate the chair the extension springing means will become completely closed and will provide a firm stop. In the cases where there is no extension springing means in front of the movement, straight extensions can be added to rotatingrocker 2 and tostationary support 3 so that the straight extensions will provide a firm forward stop, for example as inFIG. 11 . Such straight extensions can also be used even if there are extension springing means in front of the movement, for example as inFIGS. 3 , 5, 7-10 12-14. In the cases where there is neither extension springing means in front of the movement nor a possibility of adding straight extensions to rotatingrocker 2 and tostationary support 3, two blocks can be used to achieve the same effect, for example as illustrated inFIG. 18 . - As indicated above, it may be inconvenient for the sitter if the rocking chair movement is accessible when she/he leans forward to vacate the chair. Nevertheless, if the designer has a reason why the rocking chair movement should also be accessible when the sitter is leaning forward, then assemblies 5 and 6 can easily be of such extended length that another set of rotating
rocker 2 andstationary support 3 can be located on the other side ofspringing means 4. Furthermore, there is the option of having rotatingrocker 2 manufactured as one component of extended length that has a cut out roughly in the middle forspringing means 4 to be located inside, and similarly havingstationary support 3 manufactured as one component of extended length that has a cut out roughly in the middle for springingmeans 4 to be located inside. Such an alternative approach is shown inFIG. 20 , which illustrates a mechanism similar to the mechanism inFIG. 3 , except that rotatingrocker 2 andstationary support 3 are of such extended length that they provide a continuous surface that allows the rocking chair movement when the sitter is leaning forward as well as when sitting substantially upright or reclining. As illustrated, springingmeans 4 are located inside a cut out in both rotatingrocker 2 andstationary support 3. -
Rocking chair mechanism 1, which is illustrated inFIGS. 3-5 and 7-20, is an independent unit that can be manufactured separately then supplied to rocking chair manufacturers to be incorporated into their rocking chairs. Alternatively, a laterally integrated rocking chair mechanism can be part of the construction of the rocking chair itself. In either case,stationary support 3,lower assembly 6 andupper assembly 5 are all preferred options, assuitable springing means 4 can be directly attached to both a specially adapted stationary base (such aschair base 7 b inFIG. 6 ) and to a specially adapted seat (such asseat 7 a inFIG. 6 ), with rotatingrocker 2 being attached directly toseat 7 a so that it can move directly ontostationary base 7 b. -
FIGS. 3 , 5, 7-12 and 14-20 show a pair of springs in each mechanism. Alternatively, it is possible to use one spring of suitable strength or three or more springs of equivalent strength in various alternative vertical and horizontal arrangements. Other types of springing means can be used such as torsion, clock or waive springing means. The rotational movement can be achieved by virtue of a variety of mechanical means, including but not limited to: bearers (such as traditional rocking chair rotating bearers), hinges, pivots, pin-assemblies, bearings (including ball, roller, or air bearings), continuously variable joints and other forms of rotary joints or coupling.
