Definitions

• Seating furniture is also known from the prior art which has a fold-out support surface for the legs of the seated person, whereby this support surface is realized by means of a parallelogram mechanism.
• the support surfaces are therefore aligned approximately horizontally both in the congested state and in the functional state.
• the disadvantage of this is that in this case the padding thickness is limited to the support sections and that the corresponding connection lever which connect the seat with the extendable support section, are necessarily provided laterally adjacent to the support surface or break the support surface of the support section. Both are considered aesthetically disadvantageous.
• the connecting element is a rigid component, which is designed for pivotable articulation on the main segment or the base part on the one hand and the leg segment on the other hand. As rigid while a component is considered, which ensures a constant distance between the first and second pivot axis.
• the connecting means has pivoting means, such as hinge arrangements, which define the first and second pivot axes. Axles in the sense of this invention are understood to be rotary axes in a non-representational sense. An axis therefore only describes the relative mobility about an imaginary stationary axis of rotation. In this case, all known from the prior art for this purpose suitable machine elements such as bolts, axle sections, Welzlager- connections and the like.
• the translation means has a relative to the base frame or the main segment through the guide track guided purely translatable slide.
• this slide hinge means are provided, by means of which the leg segment is 29enkbar relative to the carriage about the pivot axis.
• the carriage is provided as an intermediate element between the guide track and the leg segment.
• the carriage itself is not rotationally pivotable, but follows at a transfer of the leg segment in the functional position with respect to its position and possibly also its orientation the course of the guide track.
• a component is provided in connection with this embodiment, which interacts directly with the guide track in the manner described.
• the simplest form of a carriage is when the carriage is an axle rod in the guide track, against which the leg segment is pivotable.
• the active coupling between the backrest segment and the leg segment can also take place indirectly via a slider which influences the movement of the leg segment by sliding or rolling on a control track positively coupled to the leg segment.
• a slider which influences the movement of the leg segment by sliding or rolling on a control track positively coupled to the leg segment. The operation of such a slider will be explained below.
• a first control member may be articulated with its second articulation section on the connecting member and a second control member may be articulated with its second articulation section on the leg segment.
• the static definiteness of the position of the link results from the fact that the only one degree of freedom of the connecting member relative to the main segment or the base frame deleted by the first control member. The position of the connecting member thus results completely from the position of the first control member.
• the degrees of freedom of the leg segment are also initially reduced to one degree of freedom, namely the pivotability about the second pivot axis. However, this degree of freedom is also eliminated due to the defined position of the second control member.
• the end segment in its stowed position relative to the leg segment approximately at an angle between see 50 ° and 130 ° pivoted and / or arranged approximately parallel to the main segment.
• the specified angles refer to the orientation of the seat and / or the bearing surfaces.
• a particularly advantageous comprises a slider system with a slider which is operatively coupled via a rigid auxiliary member to the end segment and which is formed as a first control portion for cooperating with a first control track whose position is positively coupled to the position of the leg segment.
• control members in the same angular position, but with different distances to the Drehorganachse on the rotary member which causes the more inwardly articulated control member is moved over the entire movement to a lesser extent than the externally articulated control member.
• the so varying movement of the control members can be used to particular advantage to control pivoting operations, in particular the pivoting operation of the leg segment.
• a connecting line between the Drehorganachse and the first articulation point of the third control member with a main extension direction of the third control member forms an angle between 60 and 120 °, when the leg segment is in its functional position.
• An angle between 60 ° and 120 °, in particular an angle of about 90 °, causes the transition From the functional state to the jam state, rotation of the rotary element initially leads to a particularly rapid relative movement of the end segment relative to the leg segment.
• the end segment can be pivoted early during the transition phase in the congestion state of the piece of furniture relative to the leg segment and then proceed with only minor relative movement together with the leg segment in the stowage position of the leg segment and thus under the main segment.
• the piece of seating furniture on a base frame wherein the main segment is designed to be movable relative to the base frame. This makes it possible on the one hand to bring the seat in an individually comfortable for the user position.
• FIG. 1 shows the mechanism of a first embodiment of a piece of seating furniture according to the invention in a view obliquely from above, 1a to 1d, the mechanism shown in Figure 1 in the transition from a congestion state to a functional state in side views,
• main segment 20, leg segment 40 and end segment 60 are arranged in a chain behind one another, wherein they form in the functional state shown in Fig. 1 is a substantially aligned and only interrupted by small distances from each other upper side surface consisting of a seat surface 22 of the main segment 20 and bearing surfaces 42, 62 of the leg segment 40 and the end segment 60 consists.
• 5a to 5h comprise sectional representations 5a, 5c, 5e, 5g of the piece of seating furniture and perspective views 5b, 5d, 5f, 5h of the mechanism.
• the mechanics is largely mirror-inverted. Components that are thereby present in duplicate are each referred to below in the singular, in which case both components are meant.
• This fastener 443 is bolted to a wooden plate 41, which forms the base for the padding of the leg segment 440.
• the second pivot axis 402 is formed by an axle pin which is provided on the L-shaped profile 445.
• the fourth pivot axis 404 is formed by an axle pin disposed at the distal end of the boom 444.
• the connecting member 480 and the positive guide member 482 together allow the leg segment 440 to pivot relative to the main segment 420, in which the leg segment 440 is deflected by the distances of the leg segments 440 Swivel axes 401, 402, 403, 404 describes predetermined path of movement that passes collision-free on the main segment 420.
