CHAIR CKPABLE OF BEING FILED UP IN A VERTICAL DIRECTION Filed March 26, 1956 2 Sheets-Sheet 2 Patented Nov. 9, 1937 CHAIR CAPABLE OF BEING PILED UP IN A VERTICAL DIRECTION Friedrich AugustSch'zidler, Arbon, Switzerland Application March 26, 1936, Serial No. 70,985 In Switzerland March 27, 1935 17 Claims.
The subject of the present invention is a chair which can be piled up with equal or similar chairs.
In the accompanying drawings Fig. 1 shows by way of example a form of construction of the chair in front elevation, the seat beingin section.
Fig. 2 shows a longitudinal section through the plane of symmetry.
Fig. 3 shows a plan of the chair and,
Fig. 4 shows a cross section of the foot.
Figs. 5, 6 and 7 show further forms of construction of the foot.
Fig. 8 shows a further form of construction of the chair in side elevation.
The chair can be piled up to an unlimited extent in the vertical direction. The condition for unlimited piling up and removal in the direction of piling is that the extensibility of the chair measured in the direction of piling must not be larger at any .point than the pile division. (Pitch) The direction of piling is determined by twosuitable points of two chairs succeeding one another in the pile, the pile. division being the-distance between these points.
The chair is constructed for example as fol lows: Tothe two parallel foot bars I, there are connected the two legs .2. the rear end of the foot bars. The legs are connected together at the top by the transverse member l. The foot bars, legs and transverse member may be formed in one piece. To the transverse member are welded the two rearwardly i'nclined back supports 3, which carry the back 4. To the lower horizontal portion of the back supports the seat 5 is secured'by means of the strengthening angle irons 6 and the bolts 8. Parallel to the foot bars there extends the supporting rail 9. On this rests the foot bar of the chair next above in the pile, whereby the pile division .is definitely determined and the other parts of the chair cannot come into contactwith. one another. In order to prevent the top chair from slipping ofi laterally, the supporting rail is constructed of channel shape at the top (Fig. v4). The railmay also be provided with transverse ribs or projections [4 which engage with recesses IS in the foot bar next above and prevent the top chair from slipping forwardly or backwardly (Figs. 5 and 6).
The legs areinclined laterally outwards and their distance apart at the upper ends measured inside, is somewhat larger than the width of the seat. The degree of inclination is determined by thethickness of the legs and the pile division.v
In Fig. 4, sindicates thepile division, (1 the thick- They are connected to ness of the leg measured at right angles to its axis, a the thickness of the leg measured in the direction of piling, and z the angle of inclination thereof. The thickness 0. decreases as the angle 2 increases (a.'=d/sin c). If now a =s then when the uppermost chair is removed from the pile the legs thereof would just pass the legs of the next lower chair. In order that the piling and removal can be effected without trouble, the pile division s is somewhat larger than a. whereby a certain amount of play is left as shown in Fig. 1.
With anincreasing division .9 the space taken up by a predetermined number of piled chairs increases. By the increase of the angle zthe spacing between the foot .bars increases and thus also the requirement of floor space. The thickness d of the legsshould therefore be as small as possible. The inclination of the back supports is effected according to the same points of View. Supporting rails, transverse member and seat are so provided thatwhen withdrawing the uppermost chair the seating surface of the next lower chair cannot be damaged as the lowest point of the transverse member is always located above the seating surface of the lower chair. Further, the supporting rail is extended forwardly to such an extent that when rolling'o-r sliding the upper, chair on the front grooved portion of the supporting .rail of the lower chair the transverse member of the first chair cannot come into. contact with the seating surface of the second chair. This rolling or sliding movement is shown in Fig. 8. By these two precautions, damaging of the chairs, even in the case of very careless piling or removal, is rendered impossible.
In Figs. 5 to 8 are shown four difierent forms.
of construction .of the foot and. supporting rail. In Fig. 5 the leg, foot bar and supporting rail consist of the same U-shaped piece of steel. In the case of the leg and foot rail this is-up-right (maximum moment of inertia). At the front curve however it is turned through 90 so that the channel is turned upwardlyassupporting rail. The footbaris provided on the under side with an indentation I5, and the supporting rail is proand secured to the foot bar. At the ends the 55 seen that the entire plane, determined by the foot,"
bar and leg, remains free. The legscouldalso be applied at the front or at the middle, the chair could be provided with four legs, without in any way affecting the capability of being piled. The foot bars I may be connected by a cross-rodor member l6 located near the front'ofthe chair,
' larly constructed rails and foot bars located on and the supporting rails 9 may be provided with notches 16 to receive the cross-bar of the next: chair, above when the chairs are piled up, as indicated in Figs. 1, 2 and 3. A lifting of the chair in the direction of piling in the present case, that is to say vertically upwards, is no longer possible in thelatter case, but it would be necessary to'move the chair, atleast to such an extent that the transverse m'ember comes to lie in front of the edge of the seat, forwardly from the pile. When this transverse member is secured to the foot barit may alsoserve for effecting a locking in the longitudinal direction. The inner flanges of the supporting rails are then provided with recesses with which engages the transverse member of the foot bar of the chair next above. The supporting rail may also be hingedly con- I nectedfto the front end of the foot bar as shown in Figqfl and then turned about the bolt l6 and raised. The rear bent portion then bears against the leg near the seat. As the leg comes' to lie in the channel of the U-shaped supporting rail, lateral movement andslipping off is not possible. The resilient chair may in this case be rendered rigid by raising the supporting rails. The supporting rail may also be so arranged that it can be raised through an angle of about In the raised position its rear'end then comes to lie against the lower edge of the seat and thus supports directly the front part of the seat.
' The supporting rails are in both'cases so dimensioned that the seat. may be" somewhat raised .whenrthe supporting rails are to be brought into their raised position. The counteracting spring force of the leg then holds the supporting rail in its raised position without further securing means. These modifications can be provided in a similar manner when the legs are secured to the front ends of the foot bars. It is then only necessary to imagine the lower frame to be turned simply through about its vertical axis.
