Device for sliding and on-the-fly storage of furniture with castors that can be pulled out Elements for the sliding displacement of the intermediate guide

BAD ORIGSNAL

Are known the devices for sliding and for on-the-fly storage of elements that can be pulled out from the bodies containing them, in particular of drawers, frames and similar to the furniture, consisting of three guides: a fixed to be attached to the furniture, a sliding element on the pull-out element to be attached and an intermediate guide.

As the displacement of the movable guide progresses, the intermediate guide becomes a displacement in the same Direction and taken along for a stroke equal to half of this moving borrowed guide, with the support of the extendable ble Element is ensured gradually as it is pulled out even with a strong overhang.

These guides are connected by sliding and supporting wheels that run idle on horizontal pins that are attached to an or other of these guides are attached and along longitudinal channels that are on the other guides, slide, available.

Usually these devices are complicated, with excessive, noisy, irregular Game and quite expensive. The subject invention closes this Out of inconveniences "and ensures a safe and noiseless Mode of operation and this with simple and cheap means, as shown below.

According to the invention, there is a fixed and a movable marriage Leadership inserted one or more intermediate roles, which can hardly be found in a special column and at the same time with the fixed and the movable guide come into contact.

For this reason, the rotation and displacement of these pods cause the sliding of the movable guide also the shift of the intermediate guide, which in one or pushed in the other direction from the front or the rear edge of the columns of this intermediate guide will.

BATH ORIGINAL

Others on pins firmly connected to the intermediate guide idling rollers complete the support, especially upstream and downstream of the intermediate rollers moving leadership.

The intermediate rollers are guided laterally by the side edges of the columns of the intermediate guide.

The movable leadership and the fixed guide show one essentially angular "C" -shaped cross-section, gebil det therefore from a vertical a / and and from two horizontal lines Walls, as the upper and lower walls of the "C" are provided with opposing channels in which the sliding and support wheels turn on the pins attached to the intermediate guide.

The intermediate guide has a horizontal wall arranged between the fixed and the movable guide, in which the öpalben for taking up the intermediate roles seen before are.

The intermediate guide has a substantially "S" shaped gene cross-section on, i.e. it points to two different ones Koten offset vertical walls, whereby the horizontal, The wall inserted between the fixed and movable guides makes the lower edge of the vertical higher Wall with the upper hand of the vertical, lower hand is connected.

The openings of the movable and the fixed guide. are arranged opposite each other for the pick-up or the sliding wheels, which are fixed to the higher '.'and and the lower' wall of the intermediate guide rotate connected pins.

The channels in the movable and fixed guides for the sliding wheels and for the intermediate rollers are on one vertical surface aligned on the center line for optimal response and balance on the pull-out Forces acting on the element.

BATH ORIGINAL

The outer edges of the columns of the intermediate guide, which the Slide intermediate rollers in one direction or the other, are covered with heads made of friction-resistant material, to facilitate the rotation of these caves.

In a preferred embodiment, there is a single intermediate roller between the fixed and the movable Guide provided, which is arranged almost in the middle of the intermediate guide.

The horizontal wall of the fixed guide is almost in the Putty a curve that is suitable for a curvature at the top and therefore to form a concavity downwards.

The former causes the end stop of the intermediate guide and prevents further advance of the intermediate roll at the end their lifting stroke.

The second ends the end stop of the intermediate guide on End of their stroke outwards when the last one behind, from the Intermediate guide carried wheel penetrates as a result of the loads acting in this concavity.

The features and purposes of the invention will appear even more clearly through the schematically illustrated implementation example that follows here;

BAD ORiGINAL

The device essentially consists of 3 guides: the fixed guide 10 with an ¹¹ C "shape to be attached to the furniture, the intermediate guide 11 with an" S "shape and the upper guide 12, which, however, is also overturned "C".

The fixed guide 10 has two horizontal walls 61 and 62 and the vertical 63. The movable guide 12 has the two horizontal walls 64 and 65 and vertical 66 on.

The intermediate guide 11 has the two vertical offset walls 67 and 68 and the horizontal 69. The fixed guide attached to the furniture through the "T" -shaped groove d has two channels 14-15 inside in which the sliding wheels 16, 17, 18 rotate.

The installation of the wheel 16, which is around the rollers 27 the intermediate guide 11 rotates, takes place through the pin 22 (Fig.3).

In a similar way, the other wheels 28-29 (Figs. 1, 3, 4) , which slide in the channels 19 and 20 of the movable guide, are installed on the intermediate guide.

Between the channel 31 of the movable guide 12 and the channel 32 of the fixed guide there is a roller 30 (Figs. 1, 2, 5, 6). This roller is housed in the rectangular gap 33 in the cement of the intermediate guide.

The smaller sides of this column are by two heads 34-35 with a "U" shape made of easy-to-slide material surrounded by to reduce the friction between the roller 30 and the edges of the gap.

A protrusion 41 protruding from the horizontal wall 62 of the fixed guide 10, obtained by the deformation the same (Fig.1), forms the stop of the end stop against which the roller 30 strikes when the intermediate guide 11 is completely has returned.

BATH ORIGINAL

The projection 4-1 forms in its interior the space for the concavity 42, which is the end stop of the guide 11 is when it is gang out and is overhung under the action of gravity.

In a horizontal cavity 45 with "0" shape, from the The upper part of the guide 12 is the position centering angle 46-4-7 and locking devices 48-49 for hooking (not shown in the figure) a frame that can be pulled out of conventional kitchen furniture is used.

Operating mode

Aenn the frame not shown in the picture is pulled out of the furniture, it moves with it Fixed movable guide 12, guided by the wheels 28 and 29.

Hence through the simultaneous touching one becomes above the roller 30 with the channel 31 of the movable guide and below with the ^ -anal 32 of the fixed guide 10 (Fig. 5, 6) the rotation and the simultaneous displacement of this .Rolle causes.

During the displacement, this roller causes pressure against the head 35 of the intermediate guide 11 and causes the displacement the latter in the same direction as that of the movable guide.

When the frame returns into the furniture, the roller 30 presses rotating and sliding against the head 34 and also forces the intermediate guide 11 to return.

during their displacement, this guide is guided by the wheels 16 and 17 attached to them, which are in the Channels 14-15 of the fixed guide 10 slide. If this Wheel 18 due to the weight of the intermediate guide 11 and overhangs the movable guide, it enters the concavity 42 of the «and 62, comes to a standstill and blocked so the intermediate guide as well as the guide 12 due to the friction of the latter on the roller 30.

BATH ORIGINAL

The postponement of the intermediate tour through the hell that is simultaneously in contact with the fixed and with the movable guide, practically causes the cancellation of the Games between the guides with a safe and noiseless operation.

All of this with simple and cheap smocks.

In summary: a smaller number of pieces than the current devices, smaller total weight, less Cost, more compactness, better practicality and Aesthetics.

Since the uses of the invention have been described as indicative rather than limiting examples, it is understood it implies that any equivalent application of the terms of the invention and every product carried out according to the features of the invention and / or functioning product is included in your protected area.
