Definitions

  • This application describes a lift system for a desk.
  • Document US 20170273453 discloses a height-adjustable desk with a desk structure, an anchor plate, a lifting device and a desktop plate.
  • the desk structure has a main structure and a holding seat.
  • the holding seat is physically included in the main frame.
  • the anchor plate is mounted on the main structure.
  • the lifting device is included in the holding bench and has a guide assembly and at least one cross-legged assembly.
  • the cross-legged assembly is extended or folded into the reception area of the holding seat and is connected and activated by the activation assembly.
  • the worktop is placed on the cross-legged assemblies in order to be moved upwards or downwards. A user looks at and operates a computer placed on the worktop when either standing or sitting and this prevents the user from remaining seated for a long period of time while working on the computer, thus avoiding harm to his/her health.
  • Document US 20180255919 discloses a height-adjustable device that comprises a base, one first scissor-like lift system connected to the base, with a first scissor-like lift system, a second scissor-like lift system connected to the base and with a second scissor-like lift system, a work surface connected to the first and second scissor-like lift systems, a support connected in a mobile fashion to the first scissor-like lift system and to the second scissor-like lift system that is mobile in relation to the work surface and a first energy storage element connected to the work surface and connected by at least one support tension element, wherein the first energy storage member is configured to put pressure on the support in a horizontal direction.
  • Another similar lift system is shown for example in US 9 681 746 B1 .
  • This application describes a lift system for a desk comprising an upper structure and a lower structure with a slider slot connected by at least two support arms comprised of sliders at one of the ends and in a scissor-like structure, a system's actuator/lock and a spring system attached to the above-mentioned upper and lower structures, and an intermediate point on the scissor-like structure.
  • the lift system for a desk includes a spring system with at least four springs in the upper structure and the lower structure.
  • the springs of the lift system for a desk work in a linear fashion along the entire length of the lifting/lowering slot.
  • At least one of the support arms of the lift system for furniture comprises a cavity.
  • the lift system's actuator/lock is manual, electric or of the gas-spring type.
  • the lift system's actuator/lock is mounted between the lower structure or the upper structure and the support arm, or the lift system's actuator/lock is mounted between the two support arms.
  • the present application describes a lift system for a desk, wherein the lift system may be activated through an actuator operated manually, electrically or pneumatically, allowing the user to easily regulate the height of the desktop.
  • the system presented herein works in a completely independent fashion, and may be used on any desk or work surface with no need for special alterations to the existing base structure. From a technical standpoint, the fact that the entire system is independent of the furniture structure means there is no need to alter or limit its layout or electrical installations.
  • the actuator (which may be manual, electric or a gas-spring) is placed horizontally and may be mounted between the lower structure or the upper structure and the support arm (A), or between the two support arms (B).
  • At least four torsion springs are attached at points C and D, operating in a linear fashion along the entire length of the desk. The purpose of these springs is to offset the weight of the structure.
  • An additional torsion spring is attached at point E.
  • the spring is adjusted on one of the support arms.
  • a cavity is created on the other support arm where the spring is mounted loosely.
  • This system allows the spring to move freely along part of the stroke of the furniture, acting at the end of the stroke.
  • the purpose of this spring is to create a greater initial force when the furniture is closed, minimizing the impulse required of the system's actuator/lock in order to initiate the movement.
  • the user can adjust the upper structure to an ideal height by activating the system's actuator/lock.
  • the system's actuator/lock which may be manual, electrical or pneumatic.
  • This system's actuator/lock is connected to the lower structure, which comprises a slider slot along which the sliders move, located at the ends of the support arms. After moving the structure, the user can activate the system's actuator/lock.
  • Figure 1 illustrates a schematic presentation of a desk with the described lift system, wherein the references indicate the following elements:
  • FIG. 2 illustrates a schematic presentation of the lift system module in the open position, wherein the references indicate the following elements:
  • FIG 3 illustrates a representation of detail "A" in Figure 1 , wherein the references indicate the following elements:
  • Figure 4 illustrates a schematic representation of the lift system module shown in front view, wherein the references indicate the following element: 6 - System's actuator/lock.
  • Figure 5 illustrates a front view of the lift system module in the closed position.
  • Figure 6 illustrates a bottom view of the lift system, wherein the references indicate the following elements:
  • the present application describes a lift system for a desk.
  • the furniture is a desk.
  • the lift system for desks thus comprises an upper structure (1) and a lower structure (3) connected by at least two support arms comprising sliders (5) located at one of the ends.
  • the two support arms form a scissor-like structure (2).
  • the system further compreses a system's actuator/lock (6) and a spring system, comprising torsion springs, attached to the above-mentioned upper (1) and lower (3) structures, in points (C) and (D), and an intermediate point (E) on the scissor-like structure (2).
  • the lower structure (3) comprises slider slots (4) to receive the sliders (5).

Claims (1)

  1. Hebesystem für einen Schreibtisch bestehend aus:
    - eine obere Struktur (1) und eine untere Struktur (3);
    - mindestens zwei Stützarme (A, B), die eine scherenartige Struktur (2) bilden, welche die obere Struktur (1) und die untere Struktur (3) verbindet;
    wobei
    - die untere Struktur (3) eine Führungsschiene umfasst, entlang derer sich Gleiter bewegen, die an den Enden der Stützarme (A, B) angeordnet sind;
    - ein Torsionsfedersystem, das an der oberen Struktur (1) und der unteren Struktur (3) befestigt ist, wobei das Torsionsfedersystem mindestens vier Torsionsfedern an zwei Befestigungspunkten (C, D) umfasst, wobei die Torsionsfedern so konfiguriert sind, dass sie linear über die gesamte Länge des Tisches wirken, um das Gewicht der Struktur auszugleichen, und eine zusätzliche Torsionsfeder, die an einem Zwischenpunkt (E) an der scherenartigen Struktur (2) befestigt ist, wobei die Torsionsfeder in dem Zwischenpunkt (E) an einem der Stützarme (A, B) und an einen Hohlraum in dem anderen Stützarm angepasst ist, in dem die Feder lose montiert ist, so dass sich die Feder entlang eines Teils des Hubs des Tisches frei bewegen kann, wobei sie am Ende des Hubs wirkt, um eine größere Anfangskraft zu erzeugen, wenn der Schreibtisch geschlossen wird, wodurch der Impuls, der von einem Aktuator/Schloss des Systems benötigt wird, um die Bewegung einzuleiten, minimiert wird;
    - ein Betätigungselement/Schloss (6) des Systems, das mit der unteren Struktur verbunden ist und horizontal angeordnet und zwischen der unteren Struktur (3) oder der oberen Struktur (1) und dem Stützarm (A) oder zwischen zwei Stützarmen (B) montiert ist, wobei das Betätigungselement/Schloss (6) des Systems manuell, elektrisch oder vom Gasfedertyp ist.
