Definitions

  • the present invention relates to a chair guide device according to the preamble of claim 1.
  • Chair guide devices are known from the prior art, which are used to support and movably guide a chair, for example in meeting rooms in public buildings.
  • the known devices are, for example, accommodated in a housing that is embedded in a floor box in the hall floor in order to enable the chair to be changed in its position along the guide to a permanently mounted table.
  • the known chair guide devices are intended to ensure that when the chair is not occupied, the chair, for example, has an inclined plane or a restoring mechanism that acts between the chair and the housing, with at least part of the restoring mechanism being arranged on or in the housing and this with the chair is connected, automatically moves to a rest or starting position in which the seat of the chair is largely below of the permanently mounted table. This can ensure that orderly chair positions are automatically assumed in order to provide sufficient passages behind the backrest surfaces of the chairs.
  • a chair guide device of the type mentioned is, for example, from DE 20 2005 005 317 U1 known to the applicant.
  • the chair is arranged on a standpipe as a chair base, which is mounted in a longitudinally displaceable manner via the carriage of a linear guide comprising two guide rails. This makes it possible to move the chair away from the table and automatically return it to the starting position as soon as the person sitting on the chair stands up. Therefore, such chair guide devices are primarily used in conference rooms or meeting rooms.
  • a device for supporting and movably guiding a chair along a guide rail designed as a monorail in which a cover plate held on a base housing part via magnets is provided in order to be able to remove this cover plate without tools, thereby providing access to height adjusters located under the cover plate to create, via which the housing as a whole can be moved into an inclined position with the guide rail.
  • the disadvantage of the known chair guide devices for moving a chair is that they either have double guide rails as linear guides, which require special care when aligning them parallel and installing them in the housing, or the linear guide is designed as a monorail, which is subject to heavy loads when moving backwards. and moving a chair occupied by a person wears out very quickly and therefore requires frequent maintenance intervals in the form of adjustment or replacement of worn components.
  • the guide rails are as resistance and noise-free as possible
  • To enable the chair to be manufactured and purchased is very expensive.
  • the installation of the mono or two mutually parallel guide rails in a chair guide device housing also requires increased assembly effort or additional manufacturing steps for the known chair guide devices.
  • An example from the prior art with a trolley chair guide is in US 2,548,066 A shown.
  • the object of the invention is to at least partially improve the chair guide devices known from the prior art.
  • the object of the present invention is to design a conceptually new chair guide device without a linear guide in the form of a mono or two parallel guide rails in a housing.
  • the present invention provides a structural change to the known chair guide devices comprising a housing that linear guides in the form of guide rails can be completely dispensed with.
  • Linear guides known from the prior art are understood to mean a linear guide of a slide between different positions A and E.
  • the housing side walls which are connected to the housing base on both sides in the longitudinal extension or are formed from a cast part or as an extruded profile as a monolithic one-piece component with the base, guide a carriage that can be moved between them in the longitudinal extension of the housing base, that is, the side walls prevent or at least restrict the carriage from breaking out at least orthogonally to the longitudinal extent of the housing base.
  • the device according to the invention provides at least one guide element, which is connected to the carriage at least in a force-fitting and/or positive manner and is thus moved with the carriage.
  • the guide element is in contact with the two side walls or is in proximity contact with the two side walls on both sides of the carriage with a small gap.
  • the guide element advantageously extends orthogonally at least in sections to the housing side walls beyond the sides of the carriage lying parallel to the side walls in such a way that sections of the guide element lying parallel to the housing side walls rest on the housing side walls on both sides of the carriage and / or a slight gap between the sections of the guide element lying parallel to the housing side walls and each remains on the housing side walls.
  • Sections of the guide element lying parallel to the housing side walls can, for example, be understood as the ends of a guide element designed in the form of a round or polygonal rod.
  • the ends are made of a different material than the rod and are connected to it at least in a non-positive and/or positive manner.
  • This has the advantage that the frictional resistance between the side walls and the guide element can be adjusted to, for example, different chair weights by selecting the material for end caps placed, for example, on the ends of the guide element designed as a rod.
  • the guide element can also advantageously be designed as an oval, ring, rectangle or as a plate with sections or side edges or sections lying orthogonally and parallel to the housing side walls. Overall, the guide element or guide elements, as described below, serve to prevent or at least limit rotational movement of the carriage about the chair leg axis.
  • At least one guide element can also be arranged on both sides of the carriage that lie parallel to the housing side walls, for example in the form of a plastic rail or in the manner of a pawn or as rolling elements that are axially mounted vertically to the housing base and which rest against the housing side walls on both sides of the carriage and be moved along these and/or with a small gap remaining, lying on both sides of the carriage in approximate contact with the housing side walls.
  • rolling elements for the carriage and rolling elements that are designed as guide elements should be understood to mean rollers, wheels, rollers, balls or a combination of at least two of the aforementioned rolling elements.
  • the rolling elements serve to support and move the carriage on the housing base.
  • the rolling elements designed as guide elements these preferably serve to support and move the carriage on and on the housing side walls.
  • At least two rolling elements namely the rollers or wheels arranged on the carriage, serve both to support and move the carriage on the housing base and as guide elements in the sense of the present invention.
  • the rolling elements are advantageously arranged on the opposite sides of the carriage lying parallel to the housing side walls and these either rest on the housing side walls or are arranged in approximate contact with the housing side walls while leaving a slight gap.
  • the cover element for example the cover that closes the housing at the top, can preferably be connected to at least one of the housing side walls and more preferably to both housing side walls at least in a force-fitting and/or positive manner.
  • blind holes with internal threads can be designed in the upper edge of the housing side walls, on which the cover element rests, into which screws guided through recesses in the cover element force - and engage positively, namely the screws are screwed into the blind holes with internal threads.
  • the cover element fixed in this way and connected to at least one of the side walls is advantageous Way from above, covering the housing, on the guide element or the guide elements, or is in approximate contact with the guide element or the guide elements while leaving a small gap, that a movement of the carriage orthogonal to the longitudinal extent of the housing base, which also means orthogonal to the longitudinal extent of the housing, is prevented or this movement is at least restricted.
  • the cover element therefore takes on the additional function of restricting or completely preventing a tilting movement of the carriage in function with the guide element or elements in or against the direction of travel.
  • the guide element or elements can therefore be assigned several functions, namely, on the one hand, the guide elements designed as rolling elements serve to support and move the carriage on the floor, and on the other hand, in conjunction with the housing side walls, they fulfill the function of a rotational movement of the carriage around the chair leg axis prevent or at least restrict this and in addition to this, the guide element or elements with the cover element have the function of preventing a tilting movement of the carriage in or against the direction of travel or limiting a tilting movement of the carriage to a minimum.
  • At least one of the housing side walls and preferably both housing side walls have a projection in the form of an angle on the upper edge opposite the housing base towards the housing side wall running parallel thereto, with a surface lying parallel to the housing base on which the guide elements rest and / or a slight gap remains between the surface parallel to the housing base and the guide elements.
  • the housing side wall or walls formed with the projection thus fulfill several functions. Take over the housing side wall or walls In addition to its function as a side wall for the housing, the additional function of restricting or completely preventing a tilting movement of the carriage through the surface lying parallel to the housing base in function with the guide element or elements in or against the direction of travel.
  • the side walls, in conjunction with the guide element or elements contacting them have the function of preventing or at least restricting a rotational movement of the carriage around the chair leg axis.
  • the side walls also serve as supports for the cover element.
  • At least one recess in the form of a groove can be formed in the cover element in the longitudinal extension to the housing base and parallel to the housing side walls, in which the rolling elements are guided when the carriage is moved.
  • two mutually parallel recesses are formed on both sides in the longitudinal extension of the housing base on the underside of the cover element, that is to say on the surface of the cover element lying towards the housing base, which, for example, guide the rolling elements of the carriage designed as roller bearings, rollers or wheels, these at least engage in sections in the recess when the cover element is placed on the housing side walls.
  • the at least one recess in the form of a groove formed in the cover element can also serve to guide the carriage in the longitudinal extent of the housing base, for example a guide element designed as a guide keel engages in the recess formed in the cover element and guides the carriage along the groove.
  • the chair can be moved in the longitudinal extension of the housing from a starting position A in the direction of a position E that is different from the starting position, whereby when the chair is moved, a drive device or resetting device is subjected to force in such a way that the change in position of the chair causes a change in the drive or restoring device acting restoring force is built up, whereby the Restoring force acts against the direction of travel from the starting position A into the different position E, so that by means of the restoring force acting on the drive or restoring device, the chair automatically moves back into the starting position A from the position E that is different from the starting position.
  • drive or resetting device is not intended to be an exhaustive list here; spring mechanisms, such as one or more roller band springs, coil springs or gas pressure dampers, spring or electric motors or a combination of at least two of the drive or resetting devices mentioned in the list are to be understood.
  • the carriage moves on a housing base designed as an inclined plane or on a housing base which, together with the housing, is installed in a floor box in an inclined position to the horizontal, for example via height adjusters.
  • the carriage In the direction of travel in the longitudinal extension of a housing from the starting position A in the direction of the position E which is different from the starting position, the carriage is moved along the slope formed by the inclined plane or the inclination of the housing, for example by a on the chair, which is connected to the carriage via the chair holder is connected, seated person moves, and automatically moves against the direction of travel against the incline along the gradient from the position E, which is different from the starting position, back to the starting position.
  • Another aspect of the invention is the partial replacement of chair guide devices that have already been installed or manufactured.
  • the housing of an already installed chair guide device installed in a floor box can remain in its installation location, but the guide rails are uninstalled in order to insert the carriage of the device according to the invention with at least one guide element arranged thereon into the housing installed in the floor box.
