DE2334114A1 - Sitting or reclining furniture - has spring assembly engaging between two support parts - Google Patents

Abstract

A seat part forms the first support part and is rotatable about a horizontal shaft in the base frame. The back part is the second support part, and is jointed to the first, with the spring assembly acting at least on it, and can be inclined in various positions. Conventionally, the point of rotation of the horizontal shaft during use of the furniture is mounted stationary on the first support part such that the part of this support part which projects forward beyond the shaft is a sufficiently long lever arm for application of a force derived from the user's thighs and relieving the rearward part of the loaded first support. Cost and arrangement of the parts of the furniture are improved, particularly for use as a seat.

Outside, for example, the locking device on the armchair according to FIG. 3 be dimensioned in such a way that it is on the same side as a support bearing in its one end position for the 3-part which is levered wide, it is 18.

Finally, it should be noted that with the armchairs according to the figures ^ a and Jb instead of the Teieskopfeder 1} of the armchair according to FIG 3 multi-stage spring arrangement «! 1Yes there are »theirs basic mode of action has already been explained above

In Figure 4, a chair is shown as a further embodiment, in which the first support part 10 is rotatable about a horizontal axis 11 is stored in Grundgeetell 12. Bas sweite stud part 18 instructs its lower end an Ansuts or boom 18 'on which the spring 16 connecting the two parts of the socket engages. At its upper isAde it has a backrest cushion 19 '. Between the first Support part 10 and the «base frame extends a locking device 23 ·» which, in deviation from what has been described so far, comes from a sole U-bracket consists of »in which there is a bracket mounted on the base frame The upper part of this strap is a screw jack 29a of the jig mounted.

It is to be pointed out that the sung examples of the figures 1 »2,3t3b and 4 seats * bsw. Show furniture in the normal position, i.e. in a position that is familiar from chairs. The support parts

can be inclined to a greater or lesser extent depending on the design and dimensions and adapted to the needs of the user »like this for example in Figure 3a.

The furniture that has been used up to now can be varied in its structure. For example, in the case of the chair according to FIG. 4, a spring arrangement 13 ″ can be provided between the first socket part and the base frame be »as indicated by the dashed line.

In all of the exemplary embodiments shown in the figures and described so far If the clamping device is attached to the base frame or to one of the locking devices, it can also be arranged be made so that the clamping device on the first support part or is mounted on a boom of the same * This has the advantage that the handle of the clamping device ^ tets on the seat surface has the same lace. Ina such floodplain for a let in dor Figure 1 indicated by dashed lines, the locking device for clarity are shown as simple dashed lines "

FIG. 5 shows an example of an embodiment for a tensioning device that becomes effective in stages. It has a thread on its ridge and is secured by means of a nut 39 '. It is also glued to the base frame Bpainstift besieged cam 34 plunges "On de * Aohse 35 sioh, also rigidly befeutigt" on both sides of the Äpannetiftes similar cam discs 36, which suaamaen with the cam 34 by pivoting a handle 51 relatively sum pen can be moved. On the dowel pin 39 are "a compression spring 36, each lined up like a" pressure plate 57 and a pressure plate 33 with a central web engaging in the longitudinal soles of the clamping pin 39. Of the locking devices shown in section, one is designed as a rod 40 "and the other as a laeohe 41 with Langlooh.

The function of the clamping device described so far is as follows When pivoting the handle 31 perpendicular to the drawing plane, » due to the shape and relative assignment of the curve

If the locking devices 40 and 41 are assigned to different mare parts, one of the supporting parts can “if desired” hold in its utensil while the other is freely movable. However, both mare parts can also be sewn freely. In accordance with the dimensioning of the cam shafts, in particular the cam disk 34, an arrangement can also be achieved as characterized in claim 7, in which one of the locking devices is also in the released state

It is also important that the first part of the stud on the horisontal «n Axis can be stored in such a way that as soon as the clamping device is opened it retains its relative position and is only durable Kraft can be locked »This» trae ·· storage can for example effected and adjusted by means of a corresponding KlesMs · Auoh can be used for weight balancing purposes of the Senutsers 4th pivot point of the horizontal Aon ·· aa Tragsr des first stUtstells 10 along its depth adjustable aneb ^ forms.
