Abstract

A guide support for drawers or like objects comprising rails adapted to be arranged on either side of the supporting article of furniture, and drawer mounted rollers guided in the rails; characterized in that the supporting rails (10, 10%) have horizontal guide portions (12) at the rear and have downwardly sloping portions (15) towards their fronts, which downwardly sloping portions subsequently rise sharply at the extreme front (17) to provide insertion-sections (18) for the drawer mounted rollers. The arrangement is such that, when the drawer or such similar object is pushed-in, it is disposed on a generally horizontal plane, but when drawn-out it slopes downwardly and forwardly to improve access to the interior. <IMAGE>

Description

SPECIFICATION A guide support for drawers The present invention relates to a guide roller support for drawers or the like objects, which comprise a double-sided arrangement with side panel supporting rails and runners on either side of the drawers guided in the supporting rails.

With known guide roller supports it is necessary for the drawers to be pulled out from the article of furniture as far as possible in order to give easier access to the contents of drawers - as shown in DE-OS 29 11 722. To achieve this mostly multi-part telescopic extensions, or such similar mechanisms, have been used.

With these known guide roller supports the easy access to the drawers is only possible when the drawers are arranged in a normal working height.

Sometimes nowadays, and especially with kitchen wall units, drawers are fitted to the free underside and in which tools, or such similar things, can be kept. These drawers are arranged at such a height that access to the contents is difficult even when the drawer is fully extended.

The purpose of this invention is to provide a guide support means for drawers, or such similar objects, which gives ready access to contents of the extended drawer, or such similar object, particularly if the drawers are arranged at eye level.

According to the present invention there is provided a guide support for drawers or the like objects for facilitating displacement comprising doublesided arrangement with supporting rails adapted to be arranged on the side of an article of furniture and runners guided in the rails, characterized in that the supporting rails have horizontal guide rails for the runners and/or sliding members and have slanting lowering or drop-sections towards their front side and where the slanting sections subsequently continue into insertion openings for the rollers and further continue into rising insertion sections, and in that two rollers are provided on either side of the drawer or such similar object, such that, when the drawer or such similar object is drawn-in they are disposed on a common horizontal plane in the horizontal guide rails.

With this design when drawer or such similar object is extended it takes up a slanting position, providing easy access to the contents - even when the drawer is located at eye level. The special design of the guide rails therefore assures that the drawer, or such similar object, cannot, unintentionally, be pulled out from the guide rails roller support.

However, the drawer can easily be placed into the guide rail roller support and again, readily be taken out of this guide rail roller support. The guide rail roller support according to the invention can still be readily assembled. The restriction to two runners or rollers on each side of the drawer is necessary in order to allow the drawer, or such similar object, which is directed through the guide rails of the supporting rails, to move into a slanting position. A definite position of extension forthe drawers, or such similar object, can be achieved in that the guide rails are designed as stopping points for the runners or rollers at the points of transition between the drop-sections and the leading-in or insertion open ings towards the horizontal guide rails.

The installation of the supporting rails into a piece of furniture, or such similar object, is made easy in that the supporting rails are designed as side-panels of a mounting frame which is completed by fron and rear-sided upper and lower cross beams.

The guide rail roller support and/or the runners in the supporting rails are secured and improved according to the design in that the designed sidepanels of the guide rails, which are shaped like a plate, are provided with an anchoring ring and in that the guide rails with the drop-sections and the insertion openings are designed as slots in the side-panels which are surrounded by edge supports and are enlarged in their depths. It is intended that the runners be preferably provided with roller grooves and that the diameter of the roller grooves corresponds to the width of the guide rails and that the width of the roller grooves corresponds with the depths of the slots in the side-panels of the supporting rails.

The noise from the running roller when drawing out the guide rail roller support, can be kept low in that the supporting rails and the guided runners (rollers) are manufactured from synthetic injection moulded parts.

According to a further development, it is intended that the guided rollers are rotatably mounted on the side-panels of a mounting frame, which is completed by a crossbeam, on which a drawer, or such similar object, can be hung. The mounting frame and the suspension frame form a prefabricated unit which can be built into a shelf of a piece of furniture.

The suspension frame should preferably be joined together from U-profile sections and the width should be widened for an extension on the front by means of an anchor plate.

According to a further development of the invention, it is intended that the suspension frame, by means of a return spring mechanism, is kept in the mounting frame when in an extended or closed position, whereby the spring mechanism is connected with one end to the lower rear cross support of the mounting frame, and with the other end to the anchor plate which is connected to the suspension fame. When extending the drawer, or such similar object, this spring mechanism gives a kind of counter-balance weight so that the drawer, or such similar object does not drop with a jerk into the extended position.

However, the mounting of the return spring mechanism can also be carried out in that in the retracted position, that is the rest position, it is retained within the mounting frame whereby the return spring mechanism is secured or locked-in with one end to the lower rear crossbeam of the mounting frame and with the other end to the suspension frame in the area of the front runners, e.g. is secured to the guide roller axle. This attachment is preferred if the guide rails of the supporting rail are provided with dead-stops.

The invention will be described further by way of example, with reference to the accompanying drawings, in which: Figure lisa plan view of a drawer guide support comprising a mounting frame with a transferable suspension frame; Figure 2 is a front elevation of the guide support according to Figure 1; Figure 3 is a cross-section, from front to back, of the guide support according to Figure 1; Figure 4 is an elevation of a side-panel of the mounting fame which becomes a supporting rail; Figure 5 is a view of the supporting rail according to Figure 4, looking on to the leading-in-opening; Figure 6 is a cross-section of the supporting rail, according to Figure 4; Figure 7 is an elevational different design of a supporting rail; Figure 8 is a view of the supporting rail according to Figure 7, seen towards the insertion opening; and Figure 9 is a cross-section of the supporting rail according Figure 7.

Figures 1 to 3 illustrate that supporting rails 10 and 10' laid out in mirror image form side-panels 24 and 25 of a mounting frame, which also has rear, front and botton crossbeams, 31,32 and 33 attached to the side panels. A transverse suspension frame is provided within this mounting frame and is made of U-shaped profile sections. Runners 40,41,42, and 43 are rotatably mounted on the side-panels 24 and 25 and said runners are disposed in the guide portions of the supporting rails 10 and 10'.

A securing plate 23 is fixed at the bottom of the front cross-beam 21 of the suspension frame and plate 23 extends to the lower rim or edge of the mounting frame The cross-beam 21 and the plate 23 have bores 22 for the attachment of an extension or screen.

The lower rear cross-beam 33 protrudes beyond the rear cross-beam 26 of the inserted suspension frame and has bore-holes 35 to enable the end of the return spring mechanism 36 to be readily secured to the mounting frame. The other end (38) of the spring mechanism 36 is secured to a borehole 23 which is designed as a U-profile section of the anchorplate.

As shown in Figure 1, the spring mechanism can also be formed in a V-shape with both ends 37 secured to the boreholes 35 of the cross-beams 33 and with hook 38 being secured to the bore-hole 26 of plate 23 and serving as a guide for the return spring mechanism 36, which has been passed through.

As shown in Figures 4 to 6, the supporting rail 10 is formed as a side-panel of the mounting frame. The plate-shaped side-panel exhibits an encircling securing edge 11 which extends towards the body of furniture with which is 16 to be secured so that it can be fitted spaced from the wall of the furniture. The supporting rail 10 has a horizontal guide rail or track portion 12 in the rearward region which leads toward the front panel via a slanting drop-section 15 continuing into an ascending insertion section 17 and subsequently leading to an insertion opening 18. The guide rail 12 of the lowering or drop-section 15 and the insertion section 17 are formed as slots in the plate-shaped side-panel whereby the boundary supports 13 and 14 enlarge the depth of the slots.

The runners 40 to 43 have grooved rollers - the diameter of the width of the slot corresponding to the depth of the slots. As can be learned from the front views of Figures 5 and 6, the leading-in or insertion opening 18 in the anchoring ring is arranged in such a way that a flange can be directed into the runner. Furthermore, it has to be mentioned that the supporting rail 10 for the opposite side is arranged exactly in mirror image to the supporting rail 10.

Once the suspension frame is pushed-in, the rollers are guided into the guide rail 12. When drawing-out the suspension frame, the front rollers 41 and 43 enter into slanting drop-sections 15 of the supporting rails 10 and 10'. A suspension frame with the drawers or such similar object secured to it is gradually lowered at the front, whereas the rear runners 40 and 42 guided in the guide rails 12 of the suspension frame, still remain on the same plane.

Once the rollers 41 and 43 reach the transition points 16, between the drop-sections 17, the extended position is reached and the drawer takes up the required slanted position in the suspension frame.

If the suspension frame is being lifted and extended further, the suspension frame, together with the drawer, can be taken out of the mounting frame, if previously the return spring mechanism has been hooked in. The reversal of direction in the insertion section 17 gives the security, so that the suspension frame cannot be unintentionally extended beyond the normal extended position. The spring 36 gives a kind of counter-balance when extending (drawing out).

As Figures 7 to 9 show, the transition between the drop-section 15 and the insertion section 17 towards the guide section 12, can be developed as a true dead-stop 19 intended for a slider or runner 39. The return spring mechanism 36 can be secured in runner 39. The spring mechanism keeps the suspension frame with the drawer in a secured, extending position. If the suspension frame is slightly lifted, the spring mechanism 36 can even independently bring the suspension frame and drawer into a drawn-in position.

It is important that the runners 40 to 43 are arranged on a common horizontal plane, and that they are fitted in the rear area of the mounting frame, and that the distance between them is less than the length of the horizontal guide rail 12 in the supporting rails 10 and 10'.

The illustrated example shows one-piece supporting rails which have the drop-section 17 and the insertion opening 18. Since all the supporting rails are housed in the furniture, the movement of the suspension frame, with the drawer hinged to it, is limited when drawing-out. The movement of drawing-out of the suspension frame, with the drawer secured to it, can be extended in that the horizontal guide rails 12 of the supporting rails 10 and 10' are each secured telescopically transversible, to at least one other guide rail.
