Abstract
A piece of furniture (10), in particular an item of office furniture or furniture for young persons, comprises body (14) from which a drawer (11 through 13) may be pulled out in a drawer motion direction (19) along a drawer path (27), such drawer running on a guide arrangement (20) on the body (14), and on two mutually opposite side portions (28 and 29), parallel to the drawer motion direction (19), of the drawer (11 through 13) gear wheels (30) synchronously coupled together are in mesh with racks (39) set on the body (14), for parallelization of the drawer (11 through 13) so that on the body the drawer does not run askew to the drawer motion direction (19). The racks (39) are constituted by tooth sections (32 and 33) on a front and/or a rear terminal section (25 and 26) of the drawer path (27). The gear wheels (30) are out of mesh with a rack (39) in a drawer path part clear of the tooth sections (32 and 33) in the front and/or the rear terminal section (25 and 26).
Description
- The invention relates to a piece of furniture and in particular office furniture or furniture for young persons, comprising a body from which a drawer may be pulled out in a drawer motion direction along a drawer path, such drawer being guided on a guide arrangement on the body, and two synchronously coupled gear wheels placed on two mutually opposite side portions, parallel to the drawer motion direction, of the drawer meshing with gear racks arranged on the body for parallel guidance of the drawer so that the drawer does not run skew and athwart the drawer motion direction on the body.
- Furniture with so-called synchronous drawers is known. In the case of known furniture the mutually coupled gear wheels on the two sides mesh with gear racks, as for example toothed bars or the like, extending continuously from the rear to the front abutment in the path of motion of the drawer. Owing to the continuously synchronized rack engagement of the gear wheels it is possible to ensure that the drawer does not run askew and/or being buckled and the drawer can not for example be pushed back in.
- The synchronized meshing of the gear wheels with the rack bars however does lead to greater frictional resistance. Pulling out the drawer from the body or pushing the drawer back in is accordingly hindered. This is however tolerated because the drawer is prevented from running skew by the synchronization.
- Accordingly it is one aim of the present invention to so improve furniture with a drawer of the type initially mentioned that on the one hand skew running of the drawer is prevented and on the other hand mechanical resistance on pulling out the drawer from the body and moving it back into the body is reduced.
- In order to attain this object in the case of piece of furniture of the type initially mentioned there is a provision such that the racks are constituted by tooth sections on a front and/or a rear terminal section of the drawer path and that the gear wheels in a drawer path part clear of the tooth sections are disengaged from a rack in the front and/or rear terminal section.
- The piece of furniture in accordance with the invention is preferably office furniture, as for instance a cabinet or a desk. However the invention is in particular applicable to furniture for young persons or for children.
- In the drawer path part in which the gear wheels are not in engagement with a rack, i. e. not in engagement with one of the tooth sections, the drawer is able to move freely, i. e. the gear wheels are stationary or are able to turn freely. The part of the drawer path in which the gear wheels are disengaged from the racks could also be named the “free section” of the drawer path. In this section there is, apart from the comparatively low friction in the guide arrangement, which for example will comprise telescoping bars, no frictional resistance to be overcome by a user of the furniture when moving the drawer. When the drawer is pulled and pushed in it runs quite freely into and out of the body. It is merely in the end sections of the drawer's path, as for example in the front and/or rear end sections, that the gear wheels are engaged for parallel guidance of the drawer with respective tooth sections and prevent skew running of the drawer. The drawer can accordingly be guided parallel to itself as far as its respective front or front terminal abutment into or out of the body.
- In the development of the invention it has been found that the gear wheels, when they clear the free section of the drawer path and arrive at the terminal sections with the racks, more or less automatically synchronize themselves and align themselves longitudinally and transversely in relation to the drawer motion direction. Admittedly it is possible for the drawer to run somewhat askew or be buckled in the middle, free section between the tooth sections at the terminal portions of the drawer path. But when the gear wheels arrive at the tooth sections, they will right the drawer and true it up with the drawer motion direction correcting any possible skew positioning or buckling of the drawer.
- The gear wheel firstly engaging a tooth section in the direction of motion of the drawer will be retarded, because it must overcome a greater resistance than the coupled gear wheel arranged at the opposite side of the drawer. When finally both gear wheels engage the tooth sections, i. e. when both gear wheels have run onto the tooth sections, the two gear wheels, which are synchronously coupled, will start to mesh with the teeth of the tooth sections and will thus true up the drawer so that the drawer is shifted on farther in the direction toward the respective abutments.
- Admittedly it is a convenient measure to provide tooth sections, which are in accordance with the invention, both on the front and also on the rear end portion of the drawer path. However in principle it is possible for example to provide short tooth sections in accordance with the invention only at the front or the rear section of the drawer path.
- The gear wheels are preferably arranged obliquely at the bottom in the rear portion of the drawer. In addition to this particularly space saving arrangement in the rear bottom corner portion of the drawer arrangements are also advantageous in which, dependent on the particular configuration, the gear wheels are arranged underneath the drawer or behind the drawer.
- In accordance with an expedient measure in accordance with the invention the front tooth sections extend as far as a front terminal abutment delimiting the path of movement of the drawer. The same is also advantageous in the case of a rear terminal abutment. Accordingly the drawer is guided in parallelism and in a synchronized manner at the respective terminal section as far as the terminal abutment.
- Between a tooth section at the terminal portion of the drawer path and a front and/or a rear terminal abutment in front of or, respectively, behind the tooth section it is also advantageous to have a clearance. This clearance is approximately so wide that the gear wheel meshing with the tooth section essentially fits between the at least one tooth section and the terminal abutment, when the drawer engages the latter. While the gear wheels are still in mesh with the tooth sections there is a higher degree of friction. When a gear wheel arrives in the free space between the tooth section and the terminal abutment, the frictional resistance and, respectively, the resistance to motion will decrease. The gear wheel will “snap” into the free clearance so that the drawer will automatically be drawn into the terminal position at the respective abutment.
- In principle it will suffice if the gear wheels mesh with the tooth sections substantially without strain in order for there to be a synchronization and parallel guidance of the drawer. An advantageous measure is however such that the gear wheels mesh with a predetermined, increased strain with the tooth sections and accordingly the drawer is retarded in the respective terminal section of the drawer path. This means that the drawer dies not hit the terminal abutment but is more or less gently retarded at it before getting as far as the terminal abutment. A measure can be advantageous in accordance with which such strain increases from the section of the drawer path outside the tooth sections as far as a front or, respectively, rear terminal portion of the tooth sections toward the respective terminal abutment. The retarding action will increase along this path as far as the respective terminal abutment.
- In accordance with a convenient feature of the invention the gear wheels are coupled with one another with the aid of a synchronizing shaft extending athwart the drawer motion direction. This synchronizing shaft may be retarded by a suitable friction bearing means and/or a brake arrangement so that the above mentioned retarding acting is attained or even improved on.
- However in accordance with one possible design of the invention it is even possible to provide for coupling of the gear wheels by means of a transmission.
- For instance a gear belt or a cable, more especially a cable provided with teeth, may be trained about the synchronous gear wheels coupled in rotation, more particularly guide pulleys connected in a torque transmitting manner, to synchronize since synchronization gear wheels meshing with the tooth sections.
- The tooth sections are best arranged on a guide part, as for example a telescoping guide, of the guide arrangement. A tooth section may constitute an integral component of the guide part, on which it is for example molded or bonded.
- However a modular design is also advantageous in the case of which the tooth sections are constituted by tooth element components. Such tooth element components may in the case of furniture in accordance with the invention be added later in order to achieve the desired synchronization or parallel guidance. The tooth element component is for example able to be arranged on the guide arrangement, f. i. able to be snapped into position, to be screwed on or the like. A particularly preferred measure is such that the tooth element component is f. i. able to be attached to the body of the furniture at a socket present on the body of the furniture, as for example holes arranged in a grid, or the like. For instance the tooth element component may comprise an angular component, on which a rack rail is arranged.
- The drawer in accordance with the invention may be locked with the aid of a single locking means. The synchronization or, respectively, parallel guidance prevents the person using the furniture, for example owing to skew movement perpendicularly to the drawing direction, from causing disengagement from the locking means, for example a lock.
- In the following some embodiments of the invention will be explained with reference to the drawings.

furniture 10 is able to be closed at the front by a roller shutter. As shown inFIG. 3 there is ashutter guide 22 on thefloor 18 for aroller shutter 22 not illustrated to run on. Thedrawers 11 through 13 are for example sliding trays with aninner partition 23. - In comparison their depth in the
drawer motion direction 19 thedrawers 11 through 13 are comparatively wide. Accordinglydrawers 11 through 13 tend to run askew on being drawn out of thebody 14 and/or on being pushed into it. However asynchronization arrangement 24 steadies thedrawers 11 through 13 at their front and rearterminal sections paths 27 of thedrawers 11 through 13 and so prevent skew running. - At two mutually
opposite side portions drawer motion direction 19gear wheels 30 are arranged coupled with a synchronizingshaft 31. Thegear wheels 30 mesh with front andrear tooth sections side walls terminal sections drawer path 27. In a middlefree section 34, lying between theterminal sections gear wheels 30 are out of engagement a rack, and in the present case with thetooth sections tooth sections terminal abutment 35 in thedrawer path 27. Theterminal abutments - In the case of the diagrammatic showing in accordance with
FIGS. 1 a through 2 b theshaft 21 runs underneath thedrawer 11. However an arrangement of theshaft 31 or, respectively, of thegear wheels 30 is more particularly space saving in a rear corner portion of thedrawer 11, as shown inFIG. 3 . - The pulling out of the
drawer 11 along thedrawer path 27 takes place as follows: - Firstly the
gear wheels 30 are engaged with therear tooth sections 33. At therear terminal section 25 thedrawer 11 is accordingly synchronized and moves in parallelism to itself so that and runs free when it is pulled out. Thedrawer 11 enters the middle,free section 34 while guided and running completely parallel, that is to say it does not run askew. Normally thedrawer 11 will move along the free section with this parallel alignment as related to the drawing direction. - Even if owing to a user clumsily grasping the
drawer 11, for example owing to taking hold of it at the side at one of theside walls section 34 the drawer runs askew in relation to thedrawer motion direction 19, thesynchronization arrangement 24 will resynchronize the drawer at the frontterminal sections 25 again. Thegear wheel 30 firstly engaging the associatedfront tooth section 32 will be retarded by thistooth section 32 until thesecond gear wheel 30 arranged on the opposite side engages or runs onto its associated front tooth section. - The two
gear wheels 30 then engage thetooth sections 32 synchronously and mesh withsuch tooth sections 32 so that thedrawer 11 arrives at the frontterminal abutment 35 synchronized and guided for parallel movement. - Mutatis mutandis the same will apply in the opposite direction, that is to say on pushing the
drawer 11 into thebody 14. - The
side walls drawers 11 through 13 may be comparatively thin and/or consist of a material which has little resistance to buckling. Nevertheless thedrawers 11 through 13 are guided along theguide arrangements 20 synchronously and in parallelism to themselves, because thesynchronization arrangement 24 prevents running askew. - The front and the
rear tooth sections tooth element components 37. Thetooth element components 37 comprise for exampleangular elements 38, as for instance bent pieces of sheet metal or plastic, with horizontally extendingracks 39 which thegear wheels 30 may engage from above. Theracks 39 are for example constituted by rack bar elements, which are set bonded, screwed or the like on abottom limb 44′ projecting past therespective drawer angle pieces 38. Theracks 39 may also be integral components of theangle pieces 38. - The
tooth element components 37 many in principle be mounted usingholes 40 arranged in a grid in theside walls tooth element components 37 may be fitted to existing furniture whensuch furniture 10 is later to be provided with a synchronizing system in accordance with the invention. Similarly like thetooth element components 37 theshaft 31 or, respectively, thegear wheels 30 may be fitted to existingdrawers 11 through 13. - A further possible design in accordance with the invention may contemplate attachment of the
angle piece 18 together with the guide rails 41 to theside walls metal angle pieces 38 can be gripped between the guide rails 41 and therespective side wall angle pieces 38 for attachment to theside wall 15, which for example are concentric withfitting holes 45 in theguide rail 41. Onelimb 44 in theangle piece 38 may f. i. extend upward, between the telescopingpart 42 and therespective side wall holes 45 in thetelescoping part 42, may also extend through thetop limb 44 and accordingly attach thetooth element component 37 to thebody 14. - In accordance with a further design the
tooth element components 37 may be integrally joined to the telescoping guides 21. For instance thetooth element components 37 can be molded on the guide rails 41, which are arranged on therespective side wall - Using the guide rails 41 by means of ball or roller bearings (not illustrated)
telescoping parts 42 are borne them in turn atelescoping part 43 is supported, for example by means of ball or roller bearings. Thetelescoping 43 are attached to the side walls of thedrawers - In the case of a piece of furniture 50 (as shown in
FIGS. 5 and 6 )drawers 51 may be pulled out of abody 52 withouter side walls 53, atop wall 54 and afloor 55. Thedrawers 51 run onguide arrangements 58 arranged oninner side walls 56 and amiddle side wall 57 in each case to the side adjacent to thedrawers 51. - Between the
inner side walls 56 and the associatedouter side walls 53 there is an intermediate space in the working embodiment, for example to receive roller shutters.Guide rails 59 of theguide arrangements 58, which for example constitute components of telescoping guides 60, are arranged on theside walls drawers 51. Thedrawers 51 are secured to the telescoping guides 60 and able to be pulled out of thebody 52 or, respectively, pushed into it. - Unlike the
furniture 10 it is only at the frontterminal sections 67 of thepaths 69 of thedrawers 51 thattooth sections 61 in accordance with the invention are arranged. At the rearterminal sections 68 of thedrawer paths 69 there are no tooth sections in accordance with the invention. This is for example expedient since thedrawers 51 are narrower than thedrawers 11 through 13 so that there is less skew running. However at the end of the drawer, viz. in the frontterminal sections 67, there will be synchronization and a parallel guiding action in accordance with the invention and furthermore a retardation of thedrawers 51 owing to thefront tooth sections 61. - The
tooth sections 61 are for example rack tooth bars 63 arranged on the top side ofprojections 62, extending in the direction of thedrawers 51, of the guide rails 59. The top racks of the rack tooth bars 63 are engaged bygear wheels 64 in the rear side portions of thedrawers 51. The rack bars 63 are arranged on the top side of theprojections 62 horizontally. The direction of their longitudinal extent corresponds to thedrawer motion direction 19. In each case twogear wheels 64 arranged on opposite sides of thedrawers 51 are coupled together by ashaft 65 in a torque transmitting manner so that thegear wheels 64 synchronously mesh with thetooth sections 61 on opposite sides of thedrawers 51 and accordingly guide thedrawers 51 in thefront end section 64 of thedrawer paths 69 in parallelism to thedrawer motion direction 19. - Furthermore the
gear wheels 64 retard thedrawers 51 when meshing with thetooth sections 61. - In the reversed direction during pushing the
drawers 51 inward thetooth sections 61, cooperating with thegear wheels 64, firstly get a synchronization and parallel guidance of thedrawer 51. Once thedrawers 51 are then on the move they may travel with little frictional resistance on farther on the next part of thedrawer path 69 as far as therear terminal section 68 or, respectively, rear terminal abutment, which is for example constituted by the telescoping guides 60. Thus the piece offurniture 50 may be readily operated. - A locking means 66, arranged for example on the
middle side wall 57 to the rear, serves for locking thedrawers 51. For instance, a lock, not visible in the drawing, is provided on the front side of thefurniture 50 for operation of the locking means 66. Furthermore the locking means 66 preferably prevents more than one drawer from being pulled out of thebody 52 at a time so that thefurniture 50 does not topple over forward. The locking means 66 accordingly serves as a catch for the drawers. - The
shafts 65 are arranged on thedrawers 51 at the rear and project downward in front of thedrawers 51 so that they do not require any space between thedrawers 51 and a rear wall, not illustrated inFIG. 5 , of thebody 52 - A particularly space saving design of a synchronizing or parallelizing guide arrangement is depicted in
FIG. 7 : in the case of a piece offurniture 70 onedrawer 71 is able to be withdrawn from abody 80 withside walls 72. Thedrawer 71 runs on a guide arrangement, not illustrated in the figure. At one of the front or rearterminal sections 82 of thepath 81 of thedrawer 71 out of thebody 80tooth sections 73 are arranged internally on theside walls 72 to mesh withgear wheels 74 on thebottom side 78 of thedrawer 71. - In contradistinction to the
tooth section tooth sections 73 are not horizontally but vertically orientated. Thegear wheels 74 are accordingly placed with their flat side parallel to thebottom side 78 and able to turn onaxles 79 on thedrawer 71. Thegear wheels 74 are coupled with each other by means of atransmission 75, in the present case in the form of a belt drive, for synchronous rotation. Onetoothed belt 76 runs aboutdrive gear wheels 77 coupling them for synchronous rotation with each other. Thegear wheels 77 are f. i. locked in rotation with thegear wheels 74 or are constituted by a second gear ring. Thetoothed belt 76 is crossed over for synchronization of thegear wheels 74 turning in opposite directions. - In accordance with a further design of the invention not illustrated the drawings gear wheels of the
type 77 employed in the gear transmissions, have a toothed belt slung around them and are juxtaposed with thegear wheels 74 and mesh with them. - The above mentioned alternative design of the invention using
synchronizing gear wheels 77 coupled by a transmission is an invention in its own right. In the case of this design of the invention continuous toothed bars could also be provided. For instance, the toothed bars would, unlike thetooth sections 73, extend right to the front essentially along the entire drawer path on theside walls 72. - In the case of a
design 10′ of thefurniture 10 in accordance withFIG. 8 thefront tooth sections 33 are arranged spaced from the frontterminal abutment 35. Between thetooth sections 32 and the frontterminal abutment 35 there is a clearance D sufficient for a part of the outer periphery of therespective gear wheel 30 in mesh with thetooth section 32 to fit between thetooth sections 32 and the frontterminal abutment 35. A corresponding clearance D is also present at the rearterminal abutment 36.
