Description

The present application enjoys the priority of German patent application DE 10 2014 002916.6, filed on 28 February 2014, the description of which is hereby incorporated by reference in its entirety.
The present invention relates in particular to movable furniture in the form of folding chairs, folding stools, folding tables. Here, movable furniture is, for example, furniture that is portable, assembleable, and disassembleable, or at least partially foldable, removable, and assembleable for use in camping or picnics. Mean.

  Such movable furniture is primarily desired to be able to shift from its intended state of use to a relatively space-saving state for portability or storage. For this purpose, in the case of folding chairs or folding tables, they are crossed together like a basket to move the folding furniture from the open position to the folded position and vice versa. Thus, it is common that a plurality of legs connected by joints are provided on the rotating shaft. And the cross point provided with the rotation shaft can be arrange | positioned at the side of the folding furniture, the front side, or the rear side.

  A folding chair having a plurality of legs connected by a joint like a heel, a seat and a back is known, for example, from German patent DE 10 2004 028 174 B4 or DE 20 2009 007 137U1.

  The main object of the present invention is to identify movable furniture that can be disassembled in the form of a folding chair or a folding table, especially without taking up space.

  This object is achieved according to the invention by means of several components as claimed in claim 1. Valid embodiments, further improvements and modifications are in the form of the dependent claims.

  For this purpose, the movable furniture is attached to a plurality of pivotable foot members, a plurality of support struts that can be attached to the legs by articulation, and to the strut ends of the plurality of support struts. In particular, it is provided with a pocket-shaped support portion, is flexible, and particularly has a cloth-made cover as a second functional portion. The legs, in particular, form a functional part and are provided and set to perform an additional function of packing other components of the furniture, in particular the support columns and the cover. The cover may also provide an additional packing function for other pieces of furniture, i.e., support posts and legs.

  An effective embodiment has a leg portion as a support member to which a plurality of foot members are connected by articulation. According to a first variant, the legs have at least three foot members supported together by joints, the foot members facing away from the joints. The end portion, that is, the leg end portion is rotatable with respect to the support member, and forms a tripod or a quadruped structure. The maximum pivot angle is less than 90 °, more preferably between 30 ° and 60 °, preferably about 45 °.

According to a further variant, the two pairs of foot members can be mounted on a cross support, in particular in the form of a transversely extending pipe or bar, separated from each other by a joint. The foot members pivoted in pairs on the respective support members so as to form the maximum pivot angle form a leg together with each other and with the support member of the column type.

  In both variants, the foot member is preferably formed in a bowl shape. Thus, they are pivoted to each other in the folded position, forming a hollow space. This space functions to receive the end of the column and the cover and constitutes the furniture packing.

  In both the modified examples, the support member constitutes a joint stopper that hits the joint side at the maximum rotation angle in order to prevent the respective foot members from rotating beyond the maximum rotation angle. It is preferable.

  It is preferred that the support strut joints be made by plug connection. For this purpose, the support member is inserted using corresponding strut ends in the region of the support member and / or in the position where the support strut is assembled in the plug opening. In the area of the support member, it has a number of, for example, collar or sleeve type plug openings corresponding to the number of support posts.

  In the assembled position, the support struts are tilted from the vertical axis, i.e., tilted upward and oriented. In this case, the tilt angle can be larger or smaller than the corresponding set up angle from horizontal to 90 °. An angle of 45 ° from the vertical or horizontal axis is suitable.

  The support struts preferably have a plurality of partial struts that can be connected to each other in the longitudinal direction of the support struts, in particular by plug connection. In this case, the length of the partial support is equal to or shorter than the length of the foot member. The partial struts here are preferably supported on each other using elastic members so that they do not come off, if applicable, of the loop type. The plug connection can here be formed by reducing the cross-sectional area of one of the joint ends of the foot member, i.e. by reducing the outer diameter, so that the inner foot member of the plug is at its joint end. It has a cross section that is shaped like a collar, i.e. it is adjusted to a corresponding inner diameter.

  For later stability, the loop-type connecting member may be provided with a plurality of joint ends that are placed at joint positions provided for attachment to a plurality of foot members. When this connecting member is attached to the leg end of the foot member, the risk of furniture sinking into a soft, sandy or granular surface is also reduced.

  In the embodiment of the furniture as a chair, it is desirable that the two pairs of support columns are provided with different lengths. In this case, the relatively short support struts of one pair of support struts are detachably connected to the legs by joints forming the front side of the seat surface, and the other pair of support struts The relatively long support strut is detachably connected to the leg at the joint forming the back. The cover, preferably in the form of support pockets at the corners, in the assembled position by the support members of the cover, so that the curved seat-shaped flexible seat and back are formed in a practical way. It is disposed on the column end portions of the pair of support columns so as to be inclined and supported.

  The effect achieved by the present invention is that the structural design of the movable furniture comprising a leg and a plurality of, in particular, four support posts that can be coupled to the leg, allows the furniture in a disassembled position to be In particular, the packing pace required for this is significantly reduced. Thus, the dimensions of the packed furniture are such that when the legs are in the assembled position in the intended position of use and when disassembled, i.e. when unassembled. In a preferred variant that performs a dual function with the packing, it is reduced to the size of the legs.

  The length of the leg corresponding to being shorter or longer than the length of the foot member is only a part of the normal leg of this type of chair or table. Therefore, the dimension of the furniture according to the present invention in the disassembled and packed position is considerably reduced compared with general folding furniture, in particular folding chairs. Thus, the disassembled movable furniture packing length is almost close to the length of the “Knirps®” brand folding umbrella.

  Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a perspective view of a chair as movable and dismountable furniture in an assembled position, including legs, support columns, a seat surface, and a back cover. FIG. 2 shows the chair with the cover removed in the display according to FIG. FIG. 3 is a perspective view of the leg portion in the form of a tripod in a state where the foot member is rotated outward with respect to the stopper (joint stopper) of the support member. FIG. 4 shows the leg in a state where the foot member is folded. FIG. 5 is a longitudinal sectional view of the leg portion showing the joint connection between the two foot members and the support member. FIG. 6 shows a modified example of a chair as movable furniture having a leg portion constituted by two pairs of leg members and a cross support member, and a cover. FIG. 7 shows the chair according to FIG. 6 with the cover removed.

  Parts that correspond to each other are given the same reference numerals in all figures.

  FIG. 1 shows a chair as a movable furniture 1 comprising a single leg 2 and a plurality of support columns 3, 4 connected to the leg by plug connection and a flexible, eg cloth cover 5. Show. The cover is in the illustrated assembled position on the free end 7 opposite to the connection end (FIG. 2) of the support struts 3 and 4 via the support pockets 6 at the corners. , Thus forming a seating surface 5a, a back (backrest) 5b and two side cover surfaces 5c. In the example of embodiment, the said leg part 2 has the three leg members 2a pivotally supported by the center support member 2b.

  In the illustrated position, the support columns 3 and 4 extend obliquely upward and outward. In FIG. 1, the inclination angle β with respect to the vertical axis V is smaller than the setup angle β ′ corresponding to 90 ° with respect to the horizontal axis H. The seating surface 5a and the back surface 5b are specified so as to be suitable for practical use from the length and inclination of the support columns 3 and 4.

  As shown in FIG. 2, the support columns 3 and 4 for the flexible cover 5 are each constituted by at least two partial columns 3a and 4a, which are arranged in the longitudinal direction of the columns. Can be plugged together at each end. For this purpose, at least some of the partial struts 3a, 4a constitute plug shafts 3b, 4b at their ends. These are plug receptacles 3c that form a corresponding bush-shaped, collar-shaped or sleeve-shaped joint of the supporting struts 3, 4 close to each other in the longitudinal direction of the struts, It is detachably locked in 4c.

  In order to stabilize the pivotable foot member 2a of the leg 2 shown in the assembled position, a loop-type or band-type connecting member 8 is connected to the star-shaped or three-legged web by means of these foot members 2a. Can be prepared to be pulled firmly in a pattern. For this purpose, the foot member forms a corresponding joint in the appropriate position to which the corresponding end 10 of the connecting member 8 can be attached, respectively, as required. In the example of this embodiment, the central surface member 11 at the midpoint of the star-shaped connecting member 8 is such that the leg 2 or the foot member 2a sinks into a soft, sandy or granular surface. Further protection to prevent this acts as an additional contact front, as is given when performing the intended use of the movable chair, ie furniture.

  3 to 5 show different forms of the leg 2. In the design according to FIG. 3, the central support member 2b is formed from a number of, for example, curved single-piece partial segments corresponding to the number of foot members 2a connected to each other. And the foot member 2a is formed so that an outer side may become a smooth surface. On the other hand, the central support member 2b is embodied as a disk in the embodiment according to FIGS. 1 and 2, and the foot member 2a is provided with a surface structure extending in the longitudinal direction of the leg portion. It has been.

  However, the leg member 2a of the leg part 2 is mainly folded as shown in FIGS. 4 and 5 with the leg part 2 provided with the leg member 2a rotated relative to the inside of the leg part 2. When in the predetermined position, it is formed in a bowl shape so that a hollow space, that is, an inner space is formed. In the folded position, the support column 3 that is disassembled into columns 3a and 4a so as to perform an additional function of accommodating a furniture portion that is configured in the example of the embodiment as a chair. , 4 and the cover 5 can also be moved into the inner space 12 of the leg 2 if applicable. Here, the column lengths of the partial columns 3a and 4a are adjusted to the length L of the hollow space 12 of the foot member 2a and the leg 2 as shown in FIG.

  The pivotability of the foot member 2a of the leg 2 with respect to the central support member 2b is obtained by the joint joint 13. For this purpose, the joint head 14 is formed on the foot member 2a at the end of the leg facing the support member 2b and is seated on the joint pin 15 of the central support member 2b. As shown in FIG. 3, in order to prevent the leg member 2a from rotating beyond the maximum rotation angle α from the vertical axis V, that is, the central axis of the leg 2, a stopper, that is, a stop-shaped portion. A (joint stopper) 16 is provided on the support member 2b. In the example of the embodiment, these are the intended collar shape part of at least partial circumferential arc shape facing the joint connection part and while the foot member 2a is pivoting outwards. It is formed by an arc-shaped recess corresponding to the groove shape of the joint head 14 of the foot member 2a to be engaged, that is, the seat portion shape portion 17. The maximum rotation angle α is specified by the positioning of the corresponding groove bottom surface 18 of the groove-shaped recess 17 of the joint head 14, and when the maximum rotation angle is reached, the foot member 2a is further rotated. Reliability is well prevented.

  The leg 2 has a number of collar or sleeve type plug openings 19 corresponding to the number of the support columns 3 and 4 so as to form a joint while mounting the support columns 3 and 4. Yes. In the example of the embodiment, the foot member 2a is inserted into these openings from the outside at the joint end. The opening is designed like a bushing. Thus, the seating of the support columns 3 and 4 in the leg 2 is ensured.

  In order to form a hollow space in the leg 2, that is, the inner space 12, a corresponding arch-shaped inner wall surface 20 (FIG. 3) is formed on the foot member 2 a at least on the inner side. These inner wall surfaces are complemented to each other so as to form at least partially closed, preferably cylindrical inner walls, when the foot member 2a is in the pivot position shown in FIGS. .

  FIGS. 6 and 7 again show a movable chair embodied as a chair having a leg 2 and support posts 3, 4 removably connected to the leg 2 as well as the seat and back cover 5. The modification of furniture is shown. The cover is placed on the support column ends of the support columns 3 and 4 using a pocket-type support member 6, and is thus detachably supported by these. The support columns 3 and 4 are constituted by a plurality of partial columns 3a and 4a that can be connected to each other by plug connection, as before.

  As in the exemplary embodiment according to FIGS. 1 to 5, the front support column 3 is shorter than the rear support column 4 in the assembly position. The seat surface 5a and the back surface 5b are formed in this way in association with the mounted cover 5. When the support struts 3 and 4 are disassembled, these partial struts 3a and 4a are supported with respect to each other in a loop-type, eg elastically connected, so that they cannot be disengaged and in a manner not further explained Yes.

  6 and 7, the leg 2 includes two pairs of foot members 2c each composed of two foot members 2a, and a cross extending between the two pairs of foot members 2c in the assembled position. It is formed by a support material (cross brace) 21. The joint of the cross support member 21 with respect to the two pairs of foot members 2c is configured by using a central support member 2b formed so as to correspond to the two partial members 2d. The partial member 2d is rotatably connected to the foot member 2a of each pair of foot members 2c via the joint connection 13 again. The joint of the cross support 21 to the partial member 2d of the central support member 2b is preferably embodied again as a plug connection. For this purpose, corresponding plug openings 22 are formed in the partial member 2d, each of the plug openings being in the assembled position at each column end of the cross support 21. Accepts in.

  The present invention is not limited to the embodiments described above. Instead, other variations of the invention may be made by those skilled in the art without losing the purpose of the invention. In particular, all the individual members described in connection with the example embodiments do not lose the object of the present invention. Further combinations can be made.

  Thus, for example, the leg 2 embodied as a tripod in FIGS. 1 to 5 comprises four leg members 2a and can therefore also be formed as a tetrapod. Furthermore, the plug opening 19 of the leg 2 can also be located elsewhere. Thus, similar to the example embodiment according to FIGS. 6 and 7, the plug opening for the support posts 3, 4 can also be provided with a similarly designed central support member 2b. . The loop-type connecting member provided if necessary can be formed of a plurality of parts and, for example, on the one hand in the central region, i.e. in the region of the joint end, and on the other hand on the free end leg In the region, it can be connected to the foot member 2a by a cross connection.

  Furthermore, the support struts 3, 4 can be embodied with the same length, and the cover 5 can be provided as a flat covering member. In this way, instead of the illustrated chair, a stool, i.e. a backless chair or table, can be assembled as a movable furniture 1 in which the surface of the chair or table is formed by a covering member. In this regard, only a suitably modified cover must be provided, and for the longer support column 4, only the partial column 4a must be omitted. As a result, both the table and the chair can be assembled and the individual parts, together with the parts shown and described, can be connected and accommodated in the legs 2.

  The leg 2 as a functional part may have a further packing function in the example of the embodiment described, but this can also be done with a cover as well. For this purpose, it can be provided with a zipper or Velcro closure for better closing of the cover 5 so as to receive the remaining parts therein for the purpose of movement and storage.
