Flexible filler closure for garbage chutes

and the like

The invention relates to waste chutes, such as them for example installed in the drain of a sink could be. More specifically, the invention relates to an improved flexible filler cap for such a garbage chute.

The known closures for garbage chutes consist of a circular ring made of flexible material that is used to Radially slotted to allow the waste to be introduced is.

However, the closure is severely weakened by this slotted training. The inward protruding segments such a focal plane shutter are only held on their outer circumference, so that such focal plane shutters escaping or “yes” waste only slightly Oppose resistance and soon become quite ineffective

Another disadvantage of the known closures is that they prevent the transmission of odors and noises from the shredding chamber into the kitchen or the work room offer little resistance.

The object of the invention is therefore to create an improved Lid or closure for garbage chutes, which can serve as a splash guard, the leakage undesirable Prevents fumes from the shredding chamber in the kitchen, which are those in the sink Prevents objects from entering the shredding chamber to fall into, which serves as a noise barrier or seal and which thrown waste into the shredding chamber returns.

To achieve this and other objects, the invention creates a flexible filler cap, which is characterized by is that it has an outer ring and an elastomeric partition wall or membrane extending inward from this Has indentations on which the [partition or membrane is gathered into gaps, and that the inner edges of the Partition wall or membrane in their unloaded state a

The filler cap according to the invention has a small one !> Entr; il opening open, without v / pus downwards and outwards Can be mobilized and expanded to their size like that Hunehnien to let that for example when pulling out of the plug can flow through large constrictions and Large food waste, such as fruit bowls, let through v. ground.

Although the shutter in the downward direction easily is expandable or expandable, it is capable of expansion to withstand depending on the pressure acting from below. The resistance to deflection and expansion in the opposite direction is essentially a downward inclination of the lock guaranteed. The inside edges of the downward sloping folds get stuck with upward pressure and cause effective blocking of an upward flow or movement and a more effective sealing of the axial opening "

acting pressure, the cover must be bent beyond an over-center or tilted position. The force required to overcome the RECOVERY Kippst needed is greater than the other for easy opening of the! Gate closure force, v ^r ie it under a load from above of the closure pressure is the case. In this regard, the closure can be referred to as having a check valve function ο

The ebr eighth structure ensures stability and strength so that a constant sagging and aging Caused loss of yield or flexibility does not result in deformation or sagging of the closure leads.

It is characteristic of the closure according to the invention only a small axillary opening when not expanded. As a result, the water collects quickly over the closure and forms an acoustic damper or a sound seal, whereby the Küciie transmitted in you luotor and crushing noises are reduced. the Configuration αer through the vertical edges of the folds formed axial opening favors the axial flow of the water, whereby the in the garbage chute through the rotating movements

The partition or membrane 10 consists of a relatively thin layer of elastomeric material, for example

Rubber or plastic, which is stranded by grit or other shaping with gathered or folded, relatively deep, alternating ribs 18 and depressions 20, which together form a series of radial folds running in a radial fashion. The folds have a relatively stable geometry and only deform as a result of overstressing the flexibility or spring action of the elastomers !! Location. In the case of the PIg. In the embodiment of the invention shown in FIG. 1, four cradles 18 and four depressions 2C are provided. Each cradle 1B has a horizontal web Zi with the geometric shape of a segment of a circle.

Each segment or wedge-shaped rib 22 goes from the circular edge 24 of the partition wall 10 and extends inwardly to a central opening 25. Each rib 18 has two vertical triangular side walls 26 which at the same time _t he form a side wall of the adjacent depressions 20th Each recess 20 has a downwardly inclined bottom web 28, which is likewise in the shape of a segment of a circle or a wedge. The side walls 26 intersect the webs 22, 28 at corner angles 12, 13, i.e. at a right angle in the illustrated embodiment, in order to impart support rigidity to the partition pleats.

Since the webs 28 are inclined downwards, they are longer than the horizontal webs 22, while the corners 13 also are longer than the corners 12 "The corners 12, 13 strive to maintain their shape. Any "expansion of the lock from its original form according to FIGS. 1 and 2 into the expanded form according to FIGS Figures 3 and 4 are due to deformation of the elastomeric material from which the membrane is made is. This widening is accompanied by an increase in the angling of the corners 12, 13, which is caused by the Resilience of the membrane is counteracted. This resilience or flexibility strives to the corners 12, 13 to return to their original bend and the "closure" in its starting position according to FIGS. 1 and 2, as soon as the deformation pressure is released.

The inner edges 29 of the side walls or flanges 26 extend together with the inner edges 14 of the webs 22 in the axial direction and the inner edges 15 of the webs 28 lay an axial passage of relatively small horizontal cross-section. Under / one from above acting pressure expand the folds 18, 20 according to FIGS. 3 and 4 easily in the downward direction, whereby the cross-section of the partition opening is greatly enlarged will.

because of the downward deflection of the partition wall only by the natural i ^l Eder effect of rubber or the like. elastomeric material from which the dividing wall is made and which is counteracted by the structural rigidity of the girders of the ribs and depressions. The corner angles 12, 13 try to flatten themselves, and the layer material gathered in the folds acts as bellows when the opening 25 is expanded.

On the other hand, there is a mechanical jamming of the parts present, which counteracts an upward deflection of the closure.

Pressure exerted on the partition from the underside, for example, by a bone whirled up by the cutting rotors, the fold is only able to fold so far upwards and bend inwards until the edges 29 of the cracks come into contact with each other, 3Sine any other Upward movement requires an over-center deflection and deformation of the gaps or overcoming the tipping point, to let the object pass. The beam strength or rigidity is such that this condition cannot occur in the formal operation of the garbage chute.

The closure has sufficient support rigidity to carry a small accumulation of water with no downward deflection to .can. Since the opening 25 is opposite to the volumetric]! Capacity of the wells 20 is small, fill the depressions 20 with water when the latter runs in faster than it can flow out through the opening 25. The trapped water therefore acts as an acoustic damper and dampens the thrust transmission from the Crushing chamber to the kitchen.
