Description

The invention relates firstly to a base, in particular for a table-top food processor, wherein the food processor has a downwardly projecting, housing-side extension, which cooperates with a, an area forming elastomeric part, preferably by means of a hard plastic part, wherein the extension formed spherically in its cooperation area is and the elastomeric part and / or the hard plastic part is formed at least partially spherical shell-like with the same radius of curvature.

Feet, especially for food processors are known. These are designed to support the food processor on a surface, in particular on a table surface, wherein more preferably over the base in the food processor caused jumps and vibrations are reduced. In this case, the elastomer part preferably consists of a rubber material or of a thermoplastic elastomer.

In view of the above-described prior art, a technical problem of the invention is seen in an advantageous way to further improve a stand of the type in question.

This problem is initially and essentially solved by the subject matter of claim 1, wherein it is pointed out that the spherical shell-like design of the elastomeric part and / or hard plastic part for mounting on the extension extends in cross section over more than 180 ° and / or that the elastomer part is designed for unwinding. According to each of the proposed approaches, more preferably according to a combination of both approaches, a pedestal of the type in question is further improved in an advantageous manner. Due to the cross-sectional configuration of the elastomer part to be held on the extension and / or the hard plastic part over more than 180 °, the ball-like formation of the cooperation region of the extension and the at least partially spherical shell-like configuration of the elastomer part and / or the hard plastic part with respect to a cross-section, further, in particular, with respect to a vertical cross-section in the operating state of the food processor, comprising a coverage of the interaction region of the extension beyond the maximum diameter of the sphere region. This leads in a preferred embodiment to a cooperation of extension and elastomer part and / or hard plastic part, in which a classic Kugelschnappverbindung can be achieved via the preferably given also in the hard plastic part elasticity. The elastomer part and / or the hard plastic part are preferably connected captively to the extension accordingly. The assembly of the elastomeric part and / or the hard plastic part on the extension is facilitated in particular by the spherical or spherical shell-like configuration of the joining partners, this with the preferred retention of a captive. More preferably, the elastomeric part and / or the hard plastic part is not tool-free to remove from the extension. In preferred alternative, more preferably combinative embodiment that for supporting example. On the table surface serving elastomer part designed for unwinding, accordingly forms a footprint, which is curved relative to the usual flat table surface or other footprint. According to this embodiment, a rotational movement between extension and elastomer part is preferably achievable between the ball-like cooperation region of the extension and in particular the spherical shell-like elastomer part caused by the food processor jumps and vibrations, while between the elastomeric part and the footprint, eg. Table surface, a translational movement is performed. In order to design the coefficient of friction for the contact surface, for example the table surface, higher than the coefficient of friction between the elastomer part and the extension on the machine side, a hard plastic part is preferably interposed between the elastomer part and the extension. The elastomer part is used accordingly in the form of a friction and damping lining. Even with the same coefficients of friction, the desired function (larger coefficient of friction to the contact surface), since the acting lever length to the pivot point of the friction point to the contact surface always generates a greater braking torque than the inner friction between extension and elastomer part and / or hard plastic part. In this case, the arrangement is further preferably selected so that, according to the preferred spherical shell-like design of the elastomeric part and / or the hard plastic part of this on the ball head of the extension according to corresponding action due to jumps or vibrations can slide, so further preferably according to a cross-section at least over 180 ° , more preferably provided over 180 ° addition concentric arrangement of ball head portion of the extension and elastomeric part and / or hard plastic part.

Further features of the invention are explained below, also in the description of the figures, often in their preferred association with the subject matter of claim 1 or with features of further claims. But they can also be in an assignment to only individual features of claim 1 or the respective further claim or each independently of importance.

Thus, it is provided in a further preferred embodiment that the unwindability is limited by a given with respect to a cross-section in the circumferential direction of the interaction surfaces between the elastomeric part and / or hard plastic part and the extension free space. The limitation may in this case be given according to striking in particular of the relative to the extension movable elastomeric part and / or hard plastic part, wherein more preferably the space provided allows the unwindability.

In this context, it proves to be further advantageous that the unwindability is preferably the same in all directions, d. H. that the elastomer part and / or the hard plastic part has no preferred unwinding direction. Thus, according to jumps and vibrations, which may be caused during operation of the food processor, in all directions rolling of the elastomeric part and / or the hard plastic part are reduced on the footprint.

The provision of the rollable elastomeric part and / or hard plastic part in a preferred basic position or in an at least approximate basic position is quasi randomly accessible in one embodiment, according to further action caused by leaps and vibrations by the food processor.

According to acting jumps or oscillations, which are caused by the food processor, and due to the possibly adjusting unwinding of the elastomer part moves quasi according to action on the hard plastic part adjusting spherical shell-like curvature portion relative to the fixed ball head portion of the extension. Preferably, in the case of a sectionally spherical shell-like curvature resulting from loading, regions are pronounced in which the elastomeric part extends to form the hard plastic part, forming a gap. Given a given unrolling of the elastomeric part, the elastomeric part facing toward the hard plastic part is shaped into a spherical shell-like curvature on the hard plastic part, more preferably non-loaded areas being spaced again according to the preferably given restoring capacity of the elastomeric part the hard plastic part and thus further preferably the inside wall have a contour deviating from a spherical shell-like curvature.

The footprint of the elastomeric part is preferably the same size in each Gleitbewegungsstellung of the extension due to the chain-like rolling movement of the elastomeric part. Accordingly, the footprint against the direction of movement is preferably reduced by the same amount as it increasingly increases in the direction of movement.

Further features of the invention are explained below, also in the description of the figures, often in their preferred association with the subject matter of claim 14, or to features of further claims. But they can also be in an assignment to only individual features of claim 14 or the respective further claim or each independently of importance.

Preferably, it is further provided that the extension is designed in the manner of a spherical segment in the cooperation region with the elastomer part. Accordingly, the extension preferably acts in a point-like manner on the elastomer part, so further preferably for minimizing the friction surface between the extension and the elastomer part. More preferably, the frictional force between extension and elastomer part is lower, more preferably substantially less than the frictional force between the elastomer part and the contact surface, for example.

Thus, the frictional force between the elastomer part and the extension preferably corresponds to 0.1 to 0.8 times the frictional force between the elastomer part and the contact surface.

Preferably, the extension cooperates with the elastomer part by means of a hard plastic part, whereby further preferably a reduction of the coefficient of friction with respect to the coefficient of friction between the elastomer part and the contact surface can be achieved. The hard plastic part is in this case further preferably firmly connected to the elastomer part, in particular to the portion of the elastomer part lying on the contact surface, for example adhesively bonded or welded. In this context, it proves to be further advantageous that the hard plastic part is preferably formed plate-like, more preferably ground plan is adapted to the always resting on the footprint surface of the elastomeric part, d.

Accordingly, the achievable due to the sliding movement of the extension extension and simultaneous reduction of the footprint is limited. In this context, it proves to be further advantageous that the elastomer part is formed in cross-section corresponding to an oval or a slot boundary. It is further preferred to form the elastomer part like a pillow, wherein the cushion wall is formed by the elastomeric material. The thus formed elastomer part is preferably opposite to the base penetrated by the extension, more preferably by the ball portion of the extension, more preferably, the peripheral edge of the interspersed by the extension engagement opening of the elastomeric part is in contact with the extension. Accordingly, the crawler-type movement of the elastomer part is preferably derived directly from the movement of the extension, this further preferably according to entrainment of the elastomer wall. In this case, a height / length ratio of 1: 2 to 1: 5, which is considered with reference to a vertical section, is preferably provided. The limited displaceability of the elastomer part, d.

As a result of this configuration, it is preferable to achieve an at least limited unwindability of the extension section having the standing surface as a function of the at least partially elastomeric configuration of the extension. This leads in a preferred manner to an improved damping of cracks and / or vibrations caused by operation of the food processor. As a result of the spherical segment-shaped base surface, an at least approximately punctual support is achieved.

Further features of the invention are explained below, also in the description of the figures, often in their preferred association with the subject matter of claim 20, or with features of further claims. But they can also be in an assignment to only individual features of claim 20 or the respective further claim or each independently of importance.

Thus, it is provided in a preferred embodiment that the extension above the Stand surface has a thinner compared to this shank area and that under stress, in particular triggered by the kitchen machine caused jumps and / or vibrations, the shaft area allows bending through the stand area by bending. In the shaft region, a pivot point or axis of rotation, which is at least temporarily set, is preferably formed in the context of a stress, around which the extension or the base surface rolls. In this case, the cone angle of the ball section region is preferably 15 to 75 °, more preferably 30 to 60 °, wherein a central support in the area of the base surface is further achieved in a preferably unloaded basic orientation of the extension.

Shown and described is first with reference to 1 a food processor 1 with a mixing vessel holder 2 and a control panel 3 ,

The food processor 1 is a mixing vessel 4 assigned. This sits in the agitator receptacle 2 one. In the mixing vessel 4 is assigned to a Rührgefäßboden an agitator provided, which has a in the food processor 1 below the picture 2 arranged, not shown electric drive is operated.

The housing 5 the food processor 1 rests on feet 6 on a riot space 7 , here on a table surface, off. The feet 6 For this purpose are below a housing bottom 8th attached, with each pedestal 6 essentially composed of a device-side attached extension 11 and one with the extension 11 cooperating elastomer part 12 ,

In the illustrated embodiments, the extension 11 preferably on a weighing beam 9 a weighing device 10 fastened, for example, screw-mounted or alternatively with the balance beam 9 welded or glued, more preferably integrally formed therewith. With regard to the design of such a weighing device 10 and the arrangement of a stand 6 on the balance beam 9 will be on the DE 10 2009 059242 A1 directed. The content of this patent application is hereby incorporated in full into the disclosure of the present invention, also for the purpose of including features of this patent application in claims of the present invention.

The food processor 1 is suitable, inter alia, for the production of doughs. In such a dough mode, a high resistance is opposed to the rotating agitator by the dough's toughness. The required drive torque of the motor is via the housing 5 and the feet 6 supported. Is the dough ball unfavorable in the mixing vessel 4 arranged, the agitator may remain briefly stuck in the dough. As a result, the torque is briefly increased. This momentum shock is from the feet 6 compensated so that the device does not jerk and jump around its center of gravity.

The movement of the housing 5 in horizontal direction (see arrow a and b in 1 ) is allowed. The housing 5 can be relative to the feet 6 or, as further preferred, relative to the elastomeric member 12 of every stand 6 move in the horizontal plane. The energetically introduced energy is thus converted into friction and / or restoring and / or deformation energy. The feet 6 are more preferred with the footprint 7 - Here table surface - frictionally connected, more preferably form one of the footprint 7 allocated stand space 27 out.

In the in the 1 to 15 illustrated embodiments consists of the base 6 essentially of two components, namely from the extension 11 , preferably of the same material and integral with the balance beam 9 is formed, and a swivel foot 13 , The extension 11 is over a shaft 14 on the balance beam 9 tethered, further preferably forms a ball head associated with the free end 15 out. Its diameter is chosen to be larger than a smallest diameter of the shaft 14 , This results preferably in the transition region of the shaft 14 to the ball head 15 a waist area 16 from which the stem starts 16 preferably in the shape of a cone towards the weight bar 9 extended, preferably up to a diameter corresponding to the diameter of the ball head 15 at least largely corresponds.

The arrangement is further chosen so that the extension 11 perpendicular to the plane extension of the weighing beam 9 runs, with one the extension 11 or the shaft 14 center passing through axis x, which further preferably at the same time also the center of the ball head 15 cuts.

The swivel foot 13 consists in a preferred embodiment of two components, namely an inner, shell-like hard plastic part 17 and in the assembly position outer, also spherical shell-like elastomer part 12 which represents a friction and damping lining.

The elastomer part 12 and the hard plastic part 17 extend in the embodiments according to the 1 to 12 in cross section at least substantially over the same angular range α, so more preferably, as also shown, over an angle of 240 °, more preferably the inner spherical shell surface of the elastomeric part 12 adapted to the spherical shell outer surface of the hard plastic part 17 ,

Hard plastic part 17 and elastomer part 12 In this case, they are preferably firmly connected to one another, so that a relative movement to one another is prevented. The connection can be achieved by gluing, more preferably according to a frictional connection.

The thus composed swivel foot 13 has according to the wrap angle α of more than 180 ° to an opening diameter d ₁ , which is smaller than the diameter d _{2 of} the ball head 15 , The opening diameter d ₁ is defined by the free opening diameter of the hard plastic part 17 ,

Due to the given elasticity of the hard plastic part 17 and the outer wall extending elastomeric part 12 is a classic ball snap connection with the ball head 15 of the extension 11 reachable. The mounted swivel foot 13 is hereafter captive on the extension 11 held, more preferably not tool-free deductible from this. Next is the swivel foot 13 in the mounting position concentric with the ball head 15 arranged, this further preferably at full contact with the inner spherical shell of the hard plastic part 17 on the facing ball head wall. Also preferred is the hard plastic part 17 not completely on the ball head 15 create, so for example, according to the design of the hard plastic part 17 in the form of a support grid or the like, in which a system is given only over the web areas.

Due to the rotationally symmetrical arrangement of swivel foot 13 and ball head 15 is the swivel foot 13 able to pivot about the ball center P ₁ . This pivoting of the swivel foot 13 is given in all directions. The unrollability of the swivel base 13 is limited by a between the swivel foot 13 and the shaft 14 of the extension 11 remaining free space 18 , This is limited by the free edge of the swivel foot 13 and the facing outer surface of the shaft 14 , whereby an angular freedom β of preferably 45 to 60 ° is established (see. 6 ).

The preferably provided hard plastic part 17 serves advantageously to the coefficient of friction between extension 11 or ball head 15 and swivel foot 13 to be interpreted as less between pivoting foot 13 and the riot space 7 ,

One as a result of the operation of the food processor 1 on the stand 6 acting load (especially vibration) leads between the extension 11 and the swivel foot 13 to a rotational movement. The swivel foot 13 rolls with its essentially point-like footprint 27 around the ball center P ₁ , this more preferably up to a stop-limited position in which the swivel foot 13 with its face against the shaft 14 occurs (cf. 6 ). Between the swivel foot 13 and the riot space 7 there is only a translatory movement.

As further from the representation in 5 to recognize, is preferably the ball center P _{1 of} the ball head 15 opposite a lower edge of the device 19 sunk arranged, this further preferably by a measure c, which corresponds to 0.2 to 0.5 times the ball head diameter d ₂ .

Next conditional in that, according to the proposed solution no horizontal deflection of the base 6 is reached, can circulating around the lowered by the measure c stand 6 a gap d be set, which is so small that the penetration of coarse material is counteracted. The gap d preferably corresponds to approximately 0.5 to 2 times the sinking dimension c.

In addition, the radial material thickness of the swivel foot corresponds 13 preferably 0.3 to 0.7 times the ball head diameter d ₂ , more preferably 0.5 times the ball head diameter d ₂ , more preferably the wall thicknesses of hard plastic part 17 and elastomer part 12 at least approximately the same. Thus, further preferably corresponds to the material thickness of the elastomeric part 12 0.75 to 1.5 times the material thickness of the hard plastic part 17 ,

The free mobility of the swivel foot 13 is positively influenced in a preferred embodiment by damping and / or restoring elements. This is in the embodiment according to the 1 to 6 achieved by one of the rolling friction of the elastomeric part 12 resulting attenuation.

In the 7 and 8th an embodiment is shown in which on the elastomeric part 12 inside the ball socket a receiving part 20 is formed. This is preferably of the same material and integral with the elastomer part 12 formed, further preferably extends in a basic orientation of the swivel foot 13 as shown in 7 pin-like, the axis x centrally receiving, this more preferably with a total central arrangement with respect to the elastomeric part 12 ,

The recording part 20 further preferably extends under frictional engagement in an axial bore 22 of the extension 11 , which axial bore 22 from the shaft 14 opposite end face region of the ball head 15 into the area of the shaft 14 extends. Preferably in the region of the shaft 14 corresponds to the inner diameter of the axial bore 22 preferably the outer diameter of the receiving part 20 , for holding the receiving part 20 , Toward the shaft 14 facing away from the ball head area is the axial bore 22 conically widened so that in the elastomer part 12 rooting section of the receiving part 20 a Ausbiege free space 23 offer.

At a load of the stand 6 and associated unwinding of the swivel foot 13 as shown in 8th becomes the recording part 20 , which continues in the area of the free end in the axial bore 22 is taken, spring-deflected, creating an elastic return of the swivel foot 13 According to rolling back around the ball center P _{1 is} reached, so that more preferably at least in a non-loaded position of the swivel foot 13 reaches its basic position, in which the receiving part 20 elongated straight.

Further preferred is an attenuation of the unwindability given by a on the elastomeric part 12 preferably directly molded, further preferably of the same material and in one piece with the elastomer part 12 trained spring extension 24 , This is in one embodiment as shown in FIG 9 outside of the outer circumference of the elastomeric part 12 provided, this further preferably under skirt-like enclosure of the spherical shell-like elastomer part 12 , The apron-like spring extension 24 This is based on the same footprint in the operating position 7 on which also the elastomer part 12 rolls. As a result of a rolling of the elastomer part 12 becomes the rolling direction facing portion of the spring extension 24 elastically deformed, so when discontinuing the load a corresponding Return preferred to the basic position or at least in the direction of the basic position is achieved.

In this is the circumferential spring extension 24 directed radially inward, this more preferably along the upward in the direction of the shaft 14 facing edge of the elastomeric part 12 , The spring extension 24 In this case, it forms an inner elastic support screen, which starts from the edge of the elastomer part 13 extends in a cross section radially inward and inclined back down. The radially inner free edge of the support umbrella-like spring extension 24 forms a rear grip area 25 out into one between the ball head 15 and the shaft 14 of the extension 11 formed support area 26 intervenes. This support area 26 is limited on the ball head side by a plane perpendicular to the axis x extending flat surface.
