Description

The invention relates to a seat / reclining furniture, in particular a chair, with a seat part and a base supporting the seat part, wherein the base has at least one bottom plate which is connected to the seat part.

Such furniture, which may be, for example, armchairs, TV armchairs or massage chairs, often have a considerable weight. Especially elderly people, it is therefore usually impossible to move the chair without excessive force. It is often desired by the users of such furniture to change the location of the chair, for example, within a room occasionally.

The object of the invention is therefore to provide a sitting / reclining furniture of the type mentioned, the location of which can be changed in a simple and reliable manner with relatively little effort, while the external appearance of the bottom plate of the furniture are at the same time affected as little as possible should.

The solution of this object is achieved by the features of claim 1. The invention provides that in the bottom plate at least one traversing device is integrated, which can be transferred from a passive position to an active position with at least partially raised bottom plate.

In a structurally comparatively simple embodiment of the invention, the traversing device comprises at least one roller or roller with an axis of rotation fixed relative to the bottom plate. Here, the furniture only needs to be tilted a little to a method of furniture by means of the roller or roller enable. The moving of the furniture is thus to a certain extent on the principle of a sack truck. The roller or roller may be arranged so that it does not touch the ground when standing on the ground floor plate. The transfer of the roller or roller in the active position then takes place by slightly tilting the furniture, ie by a partial lifting of the bottom plate. Alternatively, the roller or roller can touch the ground when the floorboard is standing on the floor. The furniture can then be transferred by tilting about the axis of rotation of the roller or roller in a ready for the process position. As a result, the bottom plate is partially raised and pivoted relative to the roller or roller, which corresponds to a transfer of the displacement device in the active position in the context of the invention.

In an alternative embodiment of the invention may be provided for the traversing a manually operable lifting mechanism, by means of which at least a part of the traversing device is adjustable for transferring to the active position with a component down relative to the bottom plate. If the traversing device is displaced beyond an upright level of the base plate that coincides with the floor standing upright, then the base plate is raised by the extending traversing device. The furniture can then be easily tilted to be subsequently brought by means of the shuttle to the respective desired location.

In a preferred embodiment of the invention, the lifting mechanism is integrated in the bottom plate.

In the case of both embodiments of the invention explained above, provision is thus made in particular for tilting the same to move the furniture. This can be done by a user simply by the fact that the user approaches the furniture from the rear, the furniture, for example in the area of a backrest or a headrest, if available, comfortably grips and draws to himself. A possibly threatening slippage of the bottom plate when tilting, the user can simply prevent it by blocking the bottom plate with his foot.

According to one embodiment of the invention, it is provided that the sitting / lying furniture can be moved by means of the traversing device only when the base plate is inclined relative to the floor.

It can be provided that the base plate can be brought by means of the traversing device from a rest position into a partially raised traversing position.

The traversing device comprises at least one traversing member. The displacement element may be a roller or roller or a sliding element.

Preferably, the furniture according to the invention is designed such that the transfer of the traversing device into the active position without relative movement between the seat part and the bottom plate is feasible. In particular, it is not necessary to rotate the seat part relative to the bottom plate.

Preferably, the traversing device is arranged in the region of the edge of the bottom plate.

In particular, it is provided that the bottom plate has a center, wherein exactly one located away from the center area of the bottom plate is provided, on which the traversing device is arranged. In this case, therefore, not just a plurality of distributed about a center around arranged Verfahrorgane such as rollers are provided. The exactly one region of the base plate on which the traversing device is located may be situated in particular on the edge of the base plate.

The traversing device preferably comprises exactly one axis of rotation for at least one roller or roller, wherein in particular the axis of rotation runs parallel or tangentially to an edge region of the bottom plate or parallel to a tangent to an edge region of the bottom plate.

The bottom plate may have a circular shape. Alternatively, the bottom plate may also have a rectangular or square basic shape.

According to a further embodiment, the base of the chair comprises at least one support connecting the seat part to the bottom plate. Preferably, exactly one support is provided in the form of a central, in particular perpendicular to the bottom plate extending support column.

If a manually operable lifting mechanism is provided for the traversing device, then according to a preferred embodiment it is provided that the lifting mechanism comprises a ratchet or ratchet mechanism.

The lifting mechanism may further comprise a rotatable by manual operation drive shaft, with which an adjusting mechanism for the traversing device is coupled, by which a rotational movement of the drive shaft in an adjusting movement of the traversing device can be implemented. The coupling between the drive shaft and adjusting mechanism can basically be done in any way. Thus, for example, a Zugseilanordnung or a gear or toothed belt arrangement may be provided for this purpose.

The adjusting mechanism may comprise a lever arrangement with at least one adjusting lever rotatably mounted about a fixed adjusting shaft spaced from the drive shaft, wherein the adjusting lever carries a traveling member, in particular a roller or roller, at a region spaced from the adjusting shaft.

According to a further embodiment of the invention, the lifting mechanism comprises an actuating element, wherein the traversing device can be converted into the active position by multiple actuation of the actuating element. The actuating element may in particular be a foot pedal.

A foot control for the lifting mechanism is not mandatory according to the invention. It may, for example, also be provided with a hand-operated lever at a basically arbitrary position of the furniture, which is coupled depending on its design and positioning with suitable means with the traversing device in order to convert these into the active position.

If a foot pedal is provided as the actuating element, then this can be at least substantially flush with an upper side of the base plate. The foot pedal thereby disturbs the formal appearance of the bottom plate only minimally, but can nevertheless be used as a design feature.

According to a further embodiment, an activation mechanism may be provided, by means of which the actuating element can be brought from a rest position into an active position which projects, in particular, from an upper side of the base plate. In the active position, the actuator is accessible to a user so that the user can easily operate the lifting mechanism.

The lifting mechanism can be designed such that the actuator can be brought back into the rest position only when brought back into the passive position traversing.

Furthermore, a return mechanism can be provided by means of which the travel device, in particular automatically, can be brought back into the passive position. The return mechanism may include one or more return springs.

It can be provided that the return mechanism can be triggered by means of an actuating element of the lifting mechanism. For this purpose, it may be provided that for triggering the return mechanism, the actuating element has to be moved starting from an active position into an overpressing position.

If the traversing device comprises at least one roller or roller with an axis of rotation fixed relative to the bottom plate, then it can be provided that an edge region of the bottom plate has a cutout, wherein the roller or roller is arranged in the cutout. In this way it can be achieved that the roller or roller bypasses the cutout to a certain extent while continuing the edge of the base plate and thus only minimally impairs the overall impression of the shape of the base plate.

For the roller or roller, two separate holding bearings may be provided, on which the roller or roller is rotatably mounted and by means of which the roller or roller is attached to the bottom plate at the same time releasably. The attachment of the roller or roller to the bottom plate can thereby be done in a particularly simple manner.

The roller or roller may be partially surrounded by a frame through which a cutout of the bottom plate provided for the roller or roller, a mounting area for the roller or roller and / or one or more fixing elements for the roller or roller are covered.

A particularly simple installation of the traversing device can be achieved in this case if, according to a further embodiment of the invention, the frame comprises at least one separate component, which is preferably attachable together with the roller or roller on the bottom plate.

According to a further embodiment, a releasable anti-rotation device is provided, which limits a relative rotatability of the seat part to the base in a securing position.

An anti-rotation is particularly advantageous in swivel chairs, since the seat part could otherwise twist during the process. However, a rotation of the seat part during the process is disturbing and affects the handling. The anti-twist device secures the seat part so that a stable seat / reclining method is possible.

In particular, the relative rotatability of the seat part to the base may be limited to a range between 0 ° and 90 °, preferably between 0 ° and 10 °. Preferably, the seat is substantially fixed and has the least possible play.

In particular, in the securing position, a backrest connected to the seat part can at least substantially assume an angular position aligned with a roller or roller of the displacement device. The seat / reclining furniture can thus be performed stable on the backrest. Alternatively, in the safety position, the backrest can also be rotated by 180 °. Here, the sitting / lying furniture can be performed, for example, stable on the armrests. According to a further embodiment, the anti-rotation device is in the active position of the displacement device in the securing position and / or in the passive position of the displacement device in a, a relative rotatability of the seat part to the base not limiting, release position. The freedom of movement of the seat part is thus limited in particular only during the process of sitting / lying furniture. In normal operation, however, a user experiences no loss of comfort and can rotate the seat part freely.

According to a further embodiment, the anti-rotation device has a projection, in particular a pin, which is arranged on a support column which connects the seat part to the base plate and cooperates with a stop which is arranged on the seat part, in particular adjustable. Such a projection can already be present in sitting / lying furniture with a fixed rotation lock. A fixed anti-rotation device can prevent the seat part in particular from being rotated more than 360 °. This is advantageous, for example, when a cable is guided out of the sitting / lying furniture, e.g. as a power supply for a massage chair. This existing projection can now be used according to the invention in addition to the releasable rotation.

According to another embodiment, the anti-rotation comprises a lever which is pivotally mounted on the seat part and adjustable between a release position and a securing position, wherein a region of the lever in the securing position, in particular the two-sided, stop for the projection. The lever can preferably be adjusted by hand. In the release position, the projection is not in engagement with the lever, so that the seat part can move freely. In the securing position, however, the projection engages in the lever and is preferably held between two stops. A stop may be formed as a plate which below the lever arranged and welded, for example. In particular, the plate can be oriented obliquely.

According to a further embodiment, the anti-rotation device can be brought into a release position, from which it automatically reaches the securing position by turning the seat part, wherein in particular a lever is adjustable in a releasable between a release position and the securing position release position, which is a locking of the lever and / or Projection in the securing position allows.

In this case, in particular a spring may be provided, which biases the lever in the release position on the support column. The stop may in particular comprise a guide for the projection, preferably an inclined plate. Consequently, if the lever is moved from the securing position to the release position, then the projection on the lever can engage as soon as it is located at a corresponding position between the attacks. The fact that the stops comprise a guide, the release position can be set at an arbitrary position of the seat part relative to the projection, i. When adjusting the lever, it is not necessary to pay attention to which position the projection is located. Namely, the lever engages automatically upon rotation of the seat part on the projection. To release the securing position, the lever can be moved back to the release position. Stable conditions in the release position and the securing position can be achieved, for example, by means of a toggle lever.

In principle, it is also possible that the lever is rigid and the projection is adjustable and can engage, for example in the manner of a push button or locking pin in the lever.

For the aspect of a releasable anti-rotation protection is claimed separately and independently of other aspects of the seat / reclining furniture described here protection, in particular independent of the traversing device, i. The positioning device is not mandatory for the anti-twist device.

Further embodiments of the invention are also set forth in the dependent claims, the description and the drawings.

An embodiment of a rotation of a seat / reclining furniture according to the invention.

First, it will be noted that the illustrated embodiments are merely exemplary in nature. The features of one embodiment may also be arbitrarily combined with features of another embodiment.

In the in the Fig. 1 to 4 shown embodiment of the invention is integrated into the cavity, not visible from the outside underneath a circular, curved bottom plate 53 of a chair, a lifting mechanism described in more detail below, which is based on the ratchet or ratchet principle.

A user first presses ( Fig. 1a ) with its foot an activation mechanism 60 by a key of the activation mechanism 60 is moved in the direction of a support column 51 which carries a seat portion 41 of the furniture.

By this actuation of the activation mechanism 60, an actuating element of the lifting mechanism in the form of a foot pedal 53 arises ( Fig. 1 b) , which was previously flush with the top of the bottom plate 43.

By repeatedly pressing the foot pedal 53 is in this embodiment, two roles (see. Fig. 2 to 4 ) extended extensor 45 downward, wherein the bottom plate 43 in the region of the shuttle 45 lifts slightly.

Once the shuttle 45 has been transferred from its previously passive position within the cavity of the bottom plate 43 in its active position, the furniture about the axis of rotation of the shuttle 45 can be tilted backwards ( Fig. 1 c) , whereby the bottom plate 53 is raised in the front area. The furniture can then be moved by rolling to a desired location.

Arrived there ( Fig. 1 d) The foot pedal is in turn moved with the foot in a push-over position by being pushed beyond the active position in the direction of the support column 51. As a result, a return mechanism is activated, which ensures that the traversing device 45 is transferred back to its passive position, whereby the bottom plate 43 is lowered back to the ground in the rear area.

Once the shuttle 45 has reached its passive position (see. Fig. 1 e) , the foot pedal 53 can be returned to the top of the bottom plate 43 flush rest position can be brought, which in turn can accomplish the user by means of his foot.

A possible embodiment for a lifting mechanism, with which the above-described functionality is feasible, will be described below in connection with the Fig. 2 to 4 explained.

For attachment of the lifting mechanism to the bottom plate 43 are brackets 54, where also other components of the lifting mechanism are supported or stored. The lifting mechanism comprises a drive shaft 55 defining a drive axis 56, an adjusting shaft 57a defining an adjusting shaft 57 with two adjusting levers 59 spaced along the adjusting shaft 57 and a rotary shaft 62 defining a pivot 49 for two rollers 47.

The said axes 56, 57, 49 are parallel to each other and are spaced from each other.

The drive shaft 55 is rotated by means of the foot pedal 53 via a ratchet mechanism comprising two ratchet wheels 58 and a detent lock 58a.

To the drive shaft 55, the actuator shaft 57a is connected via a pull cable 52, which unwinds on the drive shaft 55 and unwinds from the actuator shaft 57a, and causes rotation of the drive shaft 55 to be converted into rotation of the actuator shaft 57a. A rotation of the actuating shaft 57a results in a pivoting of the rotatably connected to the actuating shaft 57a associated lever 59, which are connected at their free ends to the rotary shaft 62, for which in the two side brackets 54 recesses are provided, in which the rotary shaft 62 in the passive position of the shuttle is added.

The rotation of the actuating shaft 57a takes place against the force of two return springs 61 in the form of torsion torsion springs, which are supported in the mounted state on the bottom plate 43 and on a lower cover, not shown.

A return spring 61 in the form of a torsion leg spring is also provided for the drive shaft 55.

When the foot pedal 53 is pivoted to the above-mentioned over-pushing position, the catch wheels 58 are released. The return springs 61 provide for a reverse rotation of the drive shaft 55 and the actuating shaft 57a, whereby the adjusting lever 59 and thus the rotary shaft 62 again return to their passive position. In this way, the rollers 47 of the shuttle 45 are again transferred back to the passive position.

Upon actuation of the activation mechanism 60 according to FIG Fig. 1 a is a tension spring 60a ( Fig. 4 ), which ensures that the foot pedal 53 is locked in its resting with the top of the bottom plate 43 rest position again when the foot pedal 53 has been pushed back by the user in the rest position ( Fig. 1 e) ,

The according to Fig. 4 By means of the pull cable 52 taking place rotational drive of the actuating shaft 57a and thus the extension of the lever 59 can be effected according to the invention in other ways. For example, between the drive shaft 55 and the actuating shaft 57a a gear arrangement or a toothed belt drive to be effective.

In the embodiment according to Fig. 5 to 14 the procedure of the furniture follows the principle of the sack truck.

The user only needs according to Fig. 5a For example, to grab the furniture on the backrest and to attract it to tilt it and then according to Fig. 5b to move in tilted position by means of a roller of the shuttle 45. At the desired location the furniture needs Fig. 5c just to be dumped back.

A particularly advantageous in terms of both function and aesthetics attachment of a traverse roller 47 is carried out according to the 6 to 14 in that the edge region of the here circular bottom plate 43 is provided with a cutout 63 and this cutout 63 is filled or bridged by the roller 47.

The traversing device 45 according to the invention comprises two separate retaining bearings 65, which can be screwed to an edge portion 71 of the bottom plate 43 in the region of the cutout 63.

Each of the retaining bearing 65 thus serving as a fastener is provided with a bearing nose 66 which engages axially in a corresponding end opening 68 of a cylindrical hub 69 on which the roller 47 is rotatably mounted.

Furthermore, the displacement device 45 comprises a frame element 67, which in the mounted state (cf. Fig. 14 ) which covers the attachment of the roller 47 to the bottom plate 43 serving areas and components between the roller 47 and the visible surface of the bottom plate 43 and thus makes invisible. The assembly and assembly of the traversing device according to the invention are in the 6 to 12 shown. A side view of the composite traversing device 45 is shown in FIG Fig. 10 shown.

The FIGS. 11 and 12 show the bottom plate 43 with attached shuttle 45 from below. Fig. 11 Among other things, it can be seen that the axis of rotation 49 of the roller 47 extends tangentially to the circular edge of the bottom plate 43 which is continued in the region of the displacement device 45.

In the FIGS. 13 and 14 the bottom plate is shown from above. In Fig. 14 For example, the top of the bottom plate 43 is shown transparently to illustrate the structure of the bottom plate 43. The bottom plate 43 here comprises a central ring 73 for receiving the support column 51 (see. Fig. 5 ), starting from which five spokes 77 extend to an outer ring 75, in which the traversing device 45 according to the invention is integrated.

The 15 to 17 show different views of a rotation 79. In Fig. 15 the underside of the seat part 41 is shown. The anti-rotation device 79 comprises a lever 81 shown in various positions, which is connected to a hinge 83 with the seat part 41 and can be adjusted in the adjustment direction R. The lever 81 is connected to a knee joint 85 and can be adjusted by a compression spring 87 from a release position F via a release position A in a securing position S. In the release position F, the seat part 41 can rotate freely relative to the bottom plate 43. In the securing position S, however, the lever 81 engages in a projection formed as a pin 89 on the supporting column 51. The pin 89 is also part of the anti-rotation 79th

In Fig. 16 a schematic side view is shown. The anti-rotation device 79 is in this case in the release position A, ie the lever 81, which as plates 91 formed stops is biased in the direction of the support column 51. However, the pin 89 is not yet locked to the lever 81. The lever 81 was displaced from the release position F, whereby now due to the oppositely bent knee joint 85, the biasing direction of the compression spring 87 has changed. If now the seat part 41 is rotated, the plates 91 of the lever 81 engage in the pin 89. The anti-rotation device 79 is then in the securing position S, which in Fig. 17 is shown. The pin 89 is hereby arranged between the plates 91. A rotation of the seat part 41 relative to the bottom plate 43 is not possible in this case, so that the seat can be moved safely.

The lever 81 can be adjusted at an arbitrary position of the seat part 41 relative to the pin 89 in the release position A. Namely, since the plates 91 are inclined, the biased lever 81 is displaced laterally upon rotation of the seat part 41 when the plates 91 hit and guided over the pin 89 before the lever 81 engages the pin 89.

To release the lever 81 is moved back out, so that the knee joint 85 is bent back in the opposite direction. The pin 89 is again out of engagement with the plates 91, so that the seat part 41 is free to move.
