Definitions

  • the present invention relates to a concatenated chair according to the preamble of claim 1.
  • Such interchangeable chairs have linking elements, also called row connectors, which are arranged laterally on the chair, partly in a fixed position, but also in such a way that they are folded in and can not protrude laterally beyond the seat surface and can be unfolded as required.
  • linking elements consist of hook-shaped, mostly vertically arranged positively and negatively shaped elements which, together with the chair to be linked, can be hooked from above into the matching linking element of the adjacent chair.
  • parts of the side frame of the chair are designed differently so that they can be hooked over the side frame of the adjacent chair, so that the fixation or concatenation of adjacent chairs takes place solely on the chair frames.
  • This type of chaining is also referred to as rack chaining.
  • a chair for a row seating which is also stackable at the same time is in the JPH08154772 A described.
  • Another example of a chair for a row seating, which is also stackable at the same time is in the DE 20 2007 000 971 U1 described.
  • This chair includes a seat, a backrest and a frame comprising, on both sides of the chair, respectively one rear and one front chair leg, which are connected to one another by means of transverse struts.
  • the toolbar of one side comprises a first connection element as an open chain eye and the toolbar on the other side comprises a second connecting element as a chain hook, the chain hook complementary to the chain eye is formed so that these connecting elements of adjacent chairs can be hooked into one another.
  • the toolbar also serves as a stacking pad on which the stacked chairs are supported.
  • a stackable row chair for a hall seating, which has a kind of joint ball as connecting elements on one side and on the other side a groove which is formed to match the ball joint, so that joint ball and groove of adjacent chairs can be hooked into each other.
  • the DE 20 2010 004 243 U1 shows a concatenated chair in which the side frame parts of the chair are designed as profile parts, so that the profile parts of adjacent chairs can be concatenated in the manner of a tongue and groove connection, by raising the one chair whose profile in the profile of the other chair can be used.
  • Chained chairs are both those with backrest and those without backrest. Depending on the type of chairs, these, in particular those with armrests, can also be called armchairs.
  • the linking parts should also be designed in such a way that the linking elements designed to be complementary to one another on the one side of the chair and on the other side of the chair have an approximately identical appearance, so that the operation of the connection technology is simple and easy for the layman understand is.
  • the present invention is based on the object to provide a concatenated chair that meets all requirements, in particular allows a secure concatenation and quickly connected in a series connection and can also be separated again.
  • the chair according to the invention which is suitable for concatenation, comprises a base frame with a seat surface part, which serves as a seat. Seen on each of the opposite sides of the seat part or the subframe transversely to the seat direction, a linking element is arranged.
  • This seat direction is defined in a right-angled xyz coordinate system as the z-direction and extends from the front edge of the chair to the rear side of the seat, while the x-direction is from the right side to the left side of the chair and the y-direction Direction perpendicular to the plane defined by the xz-direction surface, which forms the plane of the seat is.
  • the linking element on one side of the chair corresponds to the linking element on the other side of the chair, whereby adjacent, juxtaposed chairs on the linking elements are connected to each other.
  • the respective linking element of the chair is formed on the one hand in the form of a hook having a base part which is connected at its one end to the seat part or the base and at its other end has a hook portion which extends approximately in the z-direction extends.
  • the hook part thus runs at an approximately right angle to the base part.
  • the base part is oriented at an acute angle to the y-direction obliquely outwards, viewed from the seat part.
  • the hook part of the linking element on the one side of the seat part is oriented in the z-direction, starting from the end of the base part, and the hook part of the linking element on the other side of the seat part is, again starting from the end of the base part, counter to the z-direction.
  • Direction aligned is aligned.
  • the base part on one side of the seat surface part is offset by at least its cross-sectional dimension, seen in the z direction, to the base part of the linking element on the other side of the seat surface part in the z direction.
  • a locking element is provided, the interlocking of a linking element of one side of the chair in a concatenation of the other side of the chair, namely an adjacent chair, a displacement of the two linked chairs in the z direction in derogation.
  • the chair of the invention is characterized in that for the concatenation of several chairs to a continuous row of the respective chair to be chained, only slightly tilted (raised) must be laterally to push the counter-aligned to the respective base parts hook parts into each other, then the laterally raised chair is lowered back to the floor surface. Only in this lowered position the locking element of the one linking element and / or the locking element of the other linking element engages, so that when the chair is lowered it does not move against the adjacent, linked chair out of the row, that is to say according to the indicated coordinate system in FIG. Direction, can be moved or moved. When the chair is lowered, a movement in the x and y directions is prevented by the design and arrangement of the linking elements.
  • the hook parts of adjacent chairs abut one another, a consequence of the base parts, at the ends of which the hook parts are arranged, extending from the seat surface part or the frame upwards and obliquely outwards , Since the locking element on one side of the chair and the corresponding locking element on the other side of the chair, a nearly identical structure in the form of the base part and on the free At the end of the extending hook portion and, moreover, the base portions extend slightly obliquely outward on both sides of the chair, they have an identical appearance even when the chairs are interlinked.
  • an outer surface part of the underframe or the seat part which is located substantially below the mounting position of the base part, to one side of a spanned in the zy direction Surface adjoins and at least one surface part of the hook portion, which is assigned to this side of the base frame or the seat surface (above the base part), adjacent to the opposite side of this surface.
  • the locking element is formed by a projecting nose of the hook part; In an advantageous embodiment, this nose is positioned at the free end of the hook part.
  • the locking element is formed by a projection which is located on a surface of the seat surface part or of the underframe from which the base part extends.
  • the locking element of the one linking element is formed by a projection and the locking element of the other linking element is formed by a recess corresponding to the projection.
  • the above-described locking parts are to be dimensioned such that they do not engage with parts of the corresponding linking element of an adjacent chair until the chair is slightly tilted or raised laterally.
  • verkettungsNen chair can be specified on the dimensioning of the locking elements, for example over the length of the locking projection, at which tilt angle of a chair, the locking projection dissolves. This can ensure that unwanted unhooking or tilting of a single chair is prevented. Only a conscious lateral lifting in a tilted position and unhooking the Row connector by moving along the z-axis releases the engagement and thus the chairs from each other.
  • the concatenated chair without armrest in its basic structure is not different from the concatenated chair or armchair with armrest.
  • the armrests attaching to the top of the hook parts can be oriented so that they project towards each other in the lateral projection, i. seen in the x direction, have congruent positions.
  • the base parts of the two linking elements each have on their facing the seat surface inside a surface or formation, which together form (left and right) a support surface for a chair stacked above.
  • the respective linking element should be dimensioned and positioned so that it protrudes as little as possible or only slightly above the plane of the seat in the y-direction.
  • a positioning of the base part on the frame slightly below the upper edge of the seat can therefore be advantageous. In such an embodiment, however, it is important that between the seat facing side of the series connector (base part and hook part) and the seat each have a sufficiently large space for hanging the corresponding row connector of an adjacent chair.
  • the chair as shown in the figures, and referring first to the Figures 1A and 1B , comprises a base frame 1, on which a seat element 2 with a seat surface part 3 and a backrest part 4 is screwed to fastening parts 5.
  • the undercarriage 1 is a typical base frame, each with two, for example, V-shaped chair legs 6, which are connected at their upper end with two transverse tubes 7 in pairs.
  • the chair is a right-angled assigned to the xyz coordinate system.
  • the direction from the front edge 9 of the seat part 3 to the rear side 10 is defined as the z-direction.
  • the direction transverse to this seat direction is defined as the x-direction, with the x-direction and the z-direction spanning the seat surface or seat plane, and the y-direction being perpendicular to this xz plane, ie, approximately in the direction in which The backrest part 4 also extends on the rear side 10 of the seat part 3.
  • the respective linking elements are as based on the FIG. 1B can be seen, arranged on the base frame 1.
  • the respective linking element 8 has, as the particular FIG. 2A illustrates the shape of a hook, with a base portion 11 which is connected at one end to the seat portion 3 or the base 1 and at its other end a hook portion 12 has.
  • the base part 11 extends to the plane of the seat surface part 3, which is spanned by the xz axes, or to a corresponding plane of the undercarriage 1, upwards in the y-direction and obliquely outwards, this oblique direction, in FIG. 2A indicated by a dash-dotted axis 13 of the base part 11, at an acute angle, denoted by the reference numeral 14, extends to the y-direction or a plane spanned by the yz-axis plane 15.
  • the hook part 12 which attaches to the end of the base part 11, extends with its axis, which is indicated by the double-dotted, broken line 16, at an angle of approximately 90 ° to the y-axis of the seat.
  • About 90 ° means here that the angle can vary between 85 ° and 120 °, although angles of 90 ° to 95 ° are preferred.
  • the size of the acute angle 14, below which the base part 11 extends obliquely outwards depends inter alia on the length of the base part 11, its cross-sectional dimension and the cross-sectional dimension of the hook part 12.
  • the linking element 8 of a chair can be connected to the linking element 8 of an adjacent chair
  • the linking element 8 is formed on one side of a chair to the linking element 8 on the other side of the chair and thus on the other side of an adjacent chair corresponding.
  • This correspondence is achieved in that the hook part 12 extends at the end of the base part 11 of the one linking element 8 in the z-direction, while the hook portion 12 at the end of the base portion 11 of the linking element 8 on the other side of the chair, and thus also the corresponding, adjacent chair, as the FIG. 2A shows, extending against the z-direction.
  • the respective interlinking element 8 protrudes only slightly beyond the plane of the seat surface in the y direction because of its dimensioning and positioning.
  • FIG. 2A further locking elements in the form of a hole 25 on one side of the chair, preferably in the region of the surface element 19 of the base support 18, which will be described below, and in the form of a pin 26 on the other side of the chair, are provided; Hole 25 and pin 26 correspond in position and shape to each other, so that when two chairs are interlinked, they interlock.
