Description

[0001] The present invention relates to an adjustment unit for a piece of seating furniture, a piece of seating furniture and a method for assembling an adjustment unit.

[0002] Currently, there are numerous different solutions for designing height-adjustable seating. Due to increasing health awareness and higher expectations for ergonomics in schools, there is a continuous demand for innovative and robust solutions for height-adjustable seating. Disclosure of the invention

[0003] With embodiments of the invention, an improved adjustment unit for a piece of seating furniture can advantageously be provided. The invention is defined in the independent claims. Advantageous further developments of the invention are described in the dependent claims and the following description.

[0004] An advantage of the adjustment unit with the features of claim 1 is that a piece of seating furniture can allow adjustment of the seat or backrest without additional components, such as electrically height-adjustable actuators or similar devices. A further advantage is that the adjustment unit prevents height adjustment when the seat or backrest, to which the adjustment unit may be connected, is under load. Thus, a piece of seating furniture can be specifically adapted for different groups of people within the same age group as well as for different age groups, without having to operate complicated adjustment mechanisms.

[0005] This is achieved according to the invention by the adjustment unit for a piece of seating furniture comprising a first guide element, a second guide element, and a first rotary element. Furthermore, the first guide element is configured to be displaced along a first displacement direction of a first leg element of the seating furniture, wherein the second guide element is arranged substantially orthogonally to the first displacement direction on the first guide element, wherein the first rotary element is rotatably arranged on the second guide element, and wherein the rotary element is configured to lock a displacement between the first guide element and the leg element in one orientation relative to the second guide element, and wherein the rotary element is configured to release the displacement between the first guide element and the leg element in a second orientation relative to the second guide element.

[0006] In other words, the rotary element can, by means of displacement or rotation, enable and / or disable the movement of the adjustment unit towards the seat leg or the seating furniture. The first and second guide elements can be designed as single pieces or as multi-piece components. The first guide element facilitates the displacement of the adjustment unit along the leg element of the seating furniture. The second guide element preferably serves to support the first rotary element, thus acting as a guide for it. In this context, a deviation of + / - 25°, particularly due to manufacturing tolerances, can be accommodated, essentially perpendicular to the first displacement direction. Preferably, the first rotary element, in a first orientation relative to the second guide element, can displace the movement between the first guide element and the leg element.Thus, the adjustment unit is not height-adjustable in the first orientation. Preferably, the first rotary element can be arranged in a second orientation relative to the second guide element to allow movement between the first guide element and the leg element. Therefore, the first and second orientations of the first rotary element differ, making it immediately clear to the user of the seating furniture when height adjustment is activated or locked.

[0007] The dependent claims describe preferred embodiments of the invention.

[0008] Preferably, the first rotating element is configured to displace a pin element into a first opening of the leg element by means of a rotation along a second displacement direction, which is arranged substantially orthogonal to the first displacement direction, when the first rotating element is in the first orientation to lock the displacement, and wherein the first rotating element is configured to displace the pin element out of the first opening of the leg element by means of a second rotation along the second displacement direction when the first rotating element is in the second orientation to release the displacement.

[0009] An advantage of this embodiment is that the adjustment mechanism of the adjustment unit can be activated or locked by a simple rotational movement, which can be caused, for example, by lifting a seat surface. Thus, for instance, a seat surface can be folded upwards to activate the height adjustment, while when the seat surface is folded downwards, so that a person sits on it, the height adjustment is locked or deactivated. In this context, an offset of + / - 25°, essentially orthogonal to the first displacement direction, can be achieved, in particular, through manufacturing tolerances. The first rotary element and the pin element can be designed as essentially one piece or as multiple pieces. The rotary element can, by rotation, move the pin element along the second displacement direction, so that the pin element engages in a first bore or...The opening of the leg element can be engaged or moved out of it, thus enabling height adjustment. In summary, the first rotating element can convert a rotational movement of a seat surface into a translational movement of the pin element.

[0010] Preferably, the first rotating element has a first recess, wherein the first recess is configured to displace along the second displacement direction by means of the first rotation and the second rotation of the pin element in order to lock and / or release the displacement.

[0011] An advantage of this embodiment is that, by means of an elongated hole or similar in the first rotating element, the rotational movement of the rotating element can be converted into a lateral and / or translational movement, so that the pin element can be moved into or out of the opening of the leg element by means of the rotation.

[0012] Preferably, the pin element has a damping element which at least partially has an elastic material in order to protect the paintwork of the leg element.

[0013] One advantage of this embodiment is that, for example, an elastic material can be formed around the tip of the pin element, so that if the pin element partially hits the leg element, since the pin element does not completely overlap with the bore, the paintwork of the leg element can be protected, as there is no metal-on-metal contact or similar.

[0014] It is also preferable to arrange a support element on the rotating element.

[0015] An advantage of this embodiment is that the rotating element can be arranged directly on the rotating element as a seat or backrest, thus reducing assembly effort and manufacturing costs. Preferably, the support element can be arranged on the rotating element, so that a seat or backrest is located on the rotating element.

[0016] Further preferably, the adjusting unit has a rotation element, wherein the rotation element is arranged between the second guide element and the first rotary element, wherein a first connecting element is arranged between the rotation element and the first rotary element, which is configured to transmit a rotation of the rotation element to the first rotary element in order to release and / or lock the displacement.

[0017] An advantage of this embodiment is that the rotating element and the first pivoting element can be designed as two separate parts, so that the rotating element is free from displacement along the second displacement direction. This can be particularly advantageous because no torsional forces or similar forces act on a seat or backrest surface. Thus, the first pivoting element can be converted into a translation of the pin element out of or into the bore by means of a rotation that can be transferred from the rotating element to the first pivoting element. Preferably, the rotating element can be designed as a type of tube having a bore and a slot in which the respective connecting elements can be arranged. More preferably, at least one crossbar can be attached to the rotating element, which can improve the stability of a seat surface.

[0018] Preferably, the first rotating element has a third recess in which the first connecting element is guided.

[0019] An advantage of this embodiment is that a positive-locking and / or force-locking connection between the first pivoting element and the rotating element allows the rotation of the rotating element to be transferred to the first pivoting element, thus reducing play between them and simultaneously enabling translational movement. This play can be particularly disadvantageous for the user of the seating furniture, as it makes it difficult to clearly distinguish haptically whether the height adjustment is activated or deactivated. The third recess can, in particular, be a recess that projects through the first pivoting element.

[0020] Preferably, the first rotating element is arranged on the second guide element by means of a second connecting element, wherein the rotating element has a second recess in which the second connecting element is guided.

[0021] An advantage of this embodiment is that the first rotating element is securely arranged on the second guide element, while at the same time its rotation is not impeded. Preferably, the second connecting element can be arranged in an elongated hole of the first rotating element, so that the rotational movement can be converted into a lateral and / or translational movement.

[0022] Preferably, the second connecting element is designed to guide the first recess.

[0023] An advantage of this embodiment is that by designing the first recess, in particular as an elongated hole, which extends along a lateral axis as well as a rotation axis in order to form a diagonal, the conversion of the rotational movement of the first rotating element into a translational movement of the first rotating element can be improved.

[0024] It is further preferred that at least one first sliding element is arranged between the rotating element and the second guide element in order to simplify the rotation of the rotating element to the rotating element.

[0025] One advantage of this embodiment is that the play between the rotation element and the second guide element can be reduced, thus improving the user's experience of the seating furniture, as it is more clearly recognizable, especially haptically, when the adjustment unit is locked or unlocked.

[0026] Preferably the second guide element has a threaded bore in which a screw element is arranged, wherein by adjusting the screw element the screw element secures the rotating element in the first orientation and / or the second orientation.

[0027] One advantage of this design is that, during transport of the seating furniture, the adjustment unit can be locked in its rotation by pressing the screw element onto the rotating element. Thus, the adjustment unit, which is installed in a piece of seating furniture, can be secured in both the first and second orientations to simplify transport.

[0028] Preferably, a clamping element is rotatably arranged on the rotating element, wherein a leaning element can be arranged on the clamping element, wherein the first guide element and / or the second guide element has a handle element which is configured to lock and / or release a rotation of the clamping element around the rotating element.

[0029] An advantage of this embodiment is that the orientation of a backrest element, seat, or similar component arranged on the rotating element can be adjusted without activating the height adjustment between the adjustment unit and the chair leg. Thus, for example, the backrest surface can be converted into a second seat surface using the clamping element.

[0030] Preferably, the handle element is configured to engage in a bore of the clamp element by means of a locking element of the handle element, so that the clamp element can be arranged in a first predetermined orientation to the first guide element, wherein in the first predetermined orientation the leaning element forms a seat surface.

[0031] One advantage of this embodiment is that the backrest element can form a seat surface in the first predetermined orientation, while at the same time the height adjustment is not activated by the adjustment unit.

[0032] Preferably, a spring element is arranged between the rotating element and the first guide element or the second guide element, wherein the spring element is configured to align the rotating element into a second predetermined orientation and wherein the spring element is configured to form a resistance against displacement into the second orientation.

[0033] An advantage of this embodiment is that when the adjustment unit is arranged on a backrest element, the backrest element can be converted into a seat using the clamp element. By rotating the adjustment unit in the opposite direction, it can be moved into the second orientation, thus activating the height adjustment function. To prevent the height adjustment function from being accidentally activated when changing the backrest element from a backrest to a seat orientation, the spring element is designed to resist the movement of the first rotary element into the second orientation. In other words, the spring element is configured to push or pull the adjustment unit into the first orientation.

[0034] Preferably, the first guide element has at least a second sliding element which is designed to simplify the displacement between the first guide element and the leg element.

[0035] One advantage of this embodiment is that the second sliding element particularly reduces tilting between a first adjustment unit and a second adjustment unit, each of which is arranged on a leg of the seating furniture.

[0036] Preferably, the first guide element and / or the second guide element has an alignment unit which is configured to engage at least partially in a second opening of the leg element in order to simplify the insertion of the pin element into the first opening.

[0037] One advantage of this embodiment is that the pin element is not visible to the user of the seating furniture with the adjustment unit, so that the orientation of the pin element to the first opening can be significantly simplified with the help of the alignment unit, which is visible to the user.

[0038] Preferably, the alignment unit has a spring-mounted handle element which is designed to engage at least partially in a second opening in order to bring the pin element to a predetermined distance from the second opening, thus simplifying the engagement of the pin element in the first opening.

[0039] One advantage of this embodiment is that the spring-loaded handle element does not hinder the movement of the adjustment unit to the leg element, while still simplifying the orientation of the pin element to the first opening.

[0040] Preferably, the first rotary element includes a spring unit configured to provide resilient support for the pin element. An advantage of this embodiment is that if the pin element is laterally deflected to engage the opening, but is not positioned above the opening, a preload can be applied to the pin element by means of the spring unit. This preload pushes the pin element into the opening when the pin element is positioned above the opening, provided the adjusting unit is moved along the leg element. Preferably, the spring travel of the pin element by means of the spring unit is smaller than the displacement of the first rotary element.

[0041] Another aspect of the invention relates to a piece of seating furniture which has an adjustment unit as described above and below, wherein the seating furniture has at least one leg element, wherein the adjustment unit is slidably arranged on the leg element, wherein a support element is connected to a rotary element of the adjustment unit, so that by displacing the support element a movement of the adjustment unit to the leg element is enabled and / or disabled.

[0042] Preferably, the support element can be a seating element, such as a seat shell or a seat surface, as well as a backrest element, such as a backboard or similar.

[0043] Another aspect of the invention relates to a method for assembling an adjustment unit as described above and below, comprising the steps: Providing a first guide element with a second guide element, inserting a rotary element into the second guide element, securing the rotary element in the second guide element so that the rotary element can be rotated from a first orientation to a second orientation.

[0044] Furthermore, it should be noted that the term "unit" is to be understood broadly in this context and includes both single-part and multi-part designs of the respective units, whereby the respective sub-units do not necessarily have to be located in one position on the seating furniture, but can also be distributed around the seating furniture.

[0045] All disclosures described above and below with respect to one aspect of the invention shall apply equally to all other aspects of the invention.
