Opfindelsen angår en maskinsko til understøtning af emner, såsom apparater og maskiner, hvor maskinskoen har en bevægelig, metallisk spindel, der er fastgjort til et fundament ved hjælp af en låsering med et centralt hul, hvor låseringen er fastgjort i et spor på spindelen, og hvor fundamentet 5 består af en bund og en metallisk overdel, hvor bunden er udført i et polymert materiale, såsom et gummiprodukt, idet der i fundamentets polymere del er én og kun én åbning, der er indrettet til at optage spindelen, og hvor spindelens befæstning i fundamentet er skjult, samt at fundamentets overflade er udformet som en del af en kugleflade, og at der i den polymere del 10 (7) er integreret mindst to skiveformede låseringe (6) med centrale huller til fastgørelse af spindelen til fundamentet, og at låseringene er placeret parallelt og med samme centerakse, således at der mellem låseringenes centrale huller etableres et centrumspunkt.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a machine shoe for supporting items, such as apparatus and machines, wherein the machine shoe has a movable metallic spindle attached to a foundation by means of a locking ring with a central hole, the locking ring being secured in a groove on the spindle, and wherein the foundation 5 consists of a bottom and a metallic upper, the bottom being formed of a polymeric material, such as a rubber product, wherein in the polymeric portion of the foundation there is one and only one aperture adapted to receive the spindle and wherein the spindle attachment in the foundation is concealed and the surface of the foundation is formed as part of a spherical surface, and in the polymeric part 10 (7) at least two disc-shaped locking rings (6) with central holes for securing the spindle to the foundation are integrated, and the locking rings are located in parallel and with the same center axis, so that a center point is established between the central holes of the locking rings.

15 I mange applikationer, hvor maskinsko anvendes, er der store krav til hygiejne. Dette gælder eksempelvis inden for fødevare- og hospitalsbrancherne.15 In many applications where machine shoes are used, there are high standards of hygiene. This applies, for example, in the food and hospitality industries.

Den skjulte samling af maskinskoens spindel- og fundamentdel er derfor af 20 stor betydning for hygiejnen, idet den helt lukkede bund forhindrer urenheder og bakterier i at trænge op i maskinskoen fra eksempelvis et gulv eller fliseplan, på hvilket maskinskoen er placeret.The concealed assembly of the spindle and foundation part of the machine shoe is therefore of great importance to the hygiene, since the fully closed bottom prevents impurities and bacteria from entering the machine shoe from, for example, a floor or tile floor on which the machine shoe is placed.

Der kendes maskinsko, hvor spindeldelen bedre kan bevæges i forhold til 25 maskinskoens nederste del. Af disse er en type karakteristisk ved, at spindelen står oven på den nederste del af maskinskoen uden at være fastgjort til bunddelen. Dette giver imidlertid problemer i situationer, hvor emnet, som understøttes af maskinskoen, skal flyttes, idet maskinskodelene i så fald falder fra hinanden. I andre typer er spindelen i et nedre kuglehoved fast-30 gjort til den nederste del af maskinskoen, men for begge typer er det problematisk, at urenheder kan opsamles i maskinskoens samlinger.Machine shoes are known in which the spindle part can be moved better in relation to the lower part of the machine shoe. Of these, one type of characteristic is that the spindle is on top of the lower part of the machine shoe without being attached to the bottom part. However, this causes problems in situations where the workpiece supported by the machine shoe has to be moved as the machine models fall apart. In other types, the spindle in a lower ball head is attached to the lower part of the machine shoe, but for both types it is problematic that impurities can be collected in the assemblies of the machine shoe.

DK 177182 B1 2 På andre kendte maskinskotyper kan spindelen også bevæges i forhold til maskinskoens nederste del, samtidig med at spindelen er fastgjort til maskinskoens fundament. Disse maskinskotyper er karakteristiske ved, at spindelen er fastgjort til maskinskoens fundament ved montage gennem en 5 åbning i maskinskoens bund, ofte ved påskruning af en møtrik på spindelens nederste ende. Disse konstruktioner har imidlertid den ulempe, at eksempelvis urenheder og bakterier kan ophobes i hullet i maskinskoens bund, hvilket i sig selv kan udgøre et hygiejneproblem. Endvidere er der ved disse konstruktioner risiko for, at urenheder og bakterier fra åbningen i 10 maskinskoens bund kan trænge op gennem maskinskoen og derfra videre til emnet, der understøttes.GB 177182 B1 2 On other known machine types, the spindle can also be moved relative to the lower part of the machine shoe, while the spindle is attached to the foundation of the machine shoe. These machine types are characterized in that the spindle is attached to the base of the machine shoe by mounting through an opening in the bottom of the machine shoe, often by screwing in a nut on the lower end of the spindle. However, these constructions have the disadvantage that, for example, impurities and bacteria can accumulate in the hole in the bottom of the machine shoe, which in itself can pose a hygiene problem. Furthermore, in these designs there is a risk that impurities and bacteria from the opening in the bottom of the machine shoe may penetrate through the machine shoe and from there on to the supported item.

Fra US 2002/0008187 kendes en maskinsko, hvor fundamentets overflade er kugleformet, og hvor en spindel er fastgjort til maskinskoens fundament 15 ved iskruning af en bolt i spindelens nederste ende.From US 2002/0008187 a machine shoe is known in which the surface of the foundation is spherical and where a spindle is attached to the foundation shoe of the machine shoe by ice-screwing a bolt at the lower end of the spindle.

Fra DK 93 00256 U4 kendes en maskinsko med skjult befæstelse af spindelen, som monteres på emnet, som skal understøttes, i maskinskoens nederste fundament. Den har en enkelt låsering, der er integreret i et fun-20 daments polymere del. Låseringen sikrer en god befæstigelse af spindelen til fundamentet.From DK 93 00256 U4 a machine shoe with hidden fastening of the spindle, which is mounted on the workpiece to be supported, is known in the bottom foundation of the machine shoe. It has a single locking ring integrated into the polymeric portion of a base. The locking ring ensures good attachment of the spindle to the foundation.

Der er én og kun én åbning i den polymere del af maskinskoen, nemlig det hul, der optager spindelen, når den føres ind til indgreb med låseringen, 25 hvilket gør den særlig egnet til anvendelse på steder, hvor kravet til hygiejne er højt. Ved monteringen går et rundtgående spor i spindelen i indgreb med låseringen, hvorved spindelen er fastgjort.There is one and only one opening in the polymeric part of the machine shoe, namely the hole that receives the spindle when inserted into engagement with the locking ring, making it particularly suitable for use in places where the hygiene requirement is high. During mounting, a circumferential groove in the spindle engages the locking ring, thereby securing the spindle.

Opfindelsen er en udvikling af denne teknik, hvorved det bliver muligt at 30 opnå en større bevægelighed mellem spindelen og den polymere del. Den større bevægelighed fordrer, at spindelen fæstes endnu kraftigere til den DK 177182 B1 3 polymere del, hvilket har medført nogle problemer med låseringens dimensioner.The invention is a development of this technique whereby it is possible to achieve greater mobility between the spindle and the polymeric part. The greater movement requires the spindle to be even more firmly attached to the polymeric part, which has caused some problems with the dimensions of the locking ring.

Det er nu et formål med opfindelsen at tilvejebringe en maskinsko, hvor 5 spindelen kan befæstiges endnu kraftigere til fundamentet, uden at låseringens dimensioner skal øges.It is now an object of the invention to provide a machine shoe in which the spindle can be even more firmly attached to the foundation without increasing the dimensions of the locking ring.

Opfindelsens formål tilgodeses ved en maskinsko af den i indledningen til krav 1 angivne type, som er karakteristisk ved, at centrumspunktet mellem 10 låseringenes centrale huller er sammenfaldende med centrum for bevægelsen af spindelen, og ved at fundamentets kugleflade har centrum i centrumspunktet mellem de integrerede låseringes centerhuller.The object of the invention is met by a machine shoe of the type set forth in the preamble of claim 1, characterized in that the center point between the central holes of the locking rings coincides with the center of movement of the spindle and in that the ball surface of the foundation has the center at the center point between the integrated locking rings. center holes.

På denne måde opnås en tilstrækkelig stærk befæstigelse, uden at det er 15 nødvendigt at øge skoens ydre dimensioner. Centrum i låseringene er samtidig center for spindelens drejebevægelse, hvorved låseringene ved denne bevægelse deformeres hensigtsmæssigt. Endvidere opnås, at spindelen frit kan bevæges i alle retninger alene begrænset af kuglefladen.In this way, a sufficiently strong attachment is obtained, without the need to increase the outer dimensions of the shoe. The center of the locking rings is at the same time the center of rotation of the spindle, whereby the locking rings in this movement are suitably deformed. Furthermore, the spindle can be freely moved in all directions limited only by the ball surface.

20 Øvrige hensigtsmæssige udførelsesformer for understøtningen er angivet i kravene 2 til 5.Other suitable embodiments of the support are set forth in claims 2 to 5.

Opfindelsen skal herefter nærmere forklares under henvisning til tegningerne, på hvilke 25 fig. 1 viser i et tværsnit en understøtning, hvor spindelen står lodret i forhold til det nederste fundament, fig. 2 viser i et tværsnit en understøtning, hvor spindelen er drejet i forhold 30 til det nederste fundament, DK 177182 B1 4 fig. 3 viser i et tværsnit fundamentet af en understøtning, hvor to låseringe er integreret i fundamentets polymerdel; samtidig ses, at toppen af fundamentet er en del af en kugleflade, 5 fig. 4 viser samme tværsnit som fig. 3, men med kuglefladens rumvinkel-afgrænsning indtegnet.The invention will now be explained in more detail with reference to the drawings, in which FIG. 1 is a cross-sectional view showing a support in which the spindle is vertical to the lower foundation; FIG. 2 is a cross-sectional view showing a support in which the spindle is rotated in relation to the lower base; FIG. 177182 B1 4 FIG. 3 is a cross-sectional view of the foundation of a support wherein two locking rings are integrated into the polymer portion of the foundation; at the same time it can be seen that the top of the foundation is part of a ball surface, FIG. 4 shows the same cross section as fig. 3, but with the spacer delimitation of the sphere surface indicated.

På fig. 1 er vist et tværsnit af en understøtning, hvor en spindel 1 udgår fra et fundament 2. Understøtningen er vist i et snit gennem symmetriakse 9.In FIG. 1 is a cross-sectional view of a support, with a spindle 1 starting from a foundation 2. The support is shown in a section through axis of symmetry 9.

10 Spindelen 1 er forsynet med et gevind 3 til fastgørelse i det emne, som skal understøttes. Spindelen 1 er desuden forsynet med et indhak i form af en nøgleflade 4, der anvendes til tilspænding af spindelen til emnet, der skal understøttes, samt til niveaujustering. Spindelen 1 vil typisk være fremstillet i rustfrit stål.The spindle 1 is provided with a thread 3 for fastening in the workpiece to be supported. The spindle 1 is additionally provided with a notch in the form of a key surface 4, which is used for tightening the spindle to the workpiece to be supported and for level adjustment. The spindle 1 will typically be made of stainless steel.

Understøtningens fundament 2 består af et basismateriale 7, som er en polymer, såsom gummi, der ved en støbe-, lime- eller vulkaniseringsproces er forsynet med en metallisk overfladedel 8, som typisk vil være fremstillet i rustfrit stål.The foundation 2 of the support consists of a base material 7 which is a polymer, such as rubber, which, in a casting, adhesive or vulcanization process, is provided with a metallic surface part 8, which will typically be made of stainless steel.

Spindelen 1 er gennem en åbning i toppen af fundamentet 2 ført ind i fundamentet og fæstnet skjult ved indstikning af neddrejningen i enden 5 i de to viste låseringe 6. Forsøg har vist, at to låseringe giver en tilstrækkelig befæstigelseskraft mellem fundamentet 2 og spindelen 1, samtidig med at 25 udstrækningen af låseringenes 6 diameter gøres mindst mulig, hvilket muliggør, at toppen af fundamentet 2 kan udformes som en del af en kugleflade med en minimal kuglediameter.The spindle 1 is inserted into the foundation through an opening at the top of the foundation 2 and fastened concealed by inserting the pivot at the end 5 of the two locking rings 6. Experiments have shown that two locking rings provide a sufficient fastening force between the foundation 2 and the spindle 1. while minimizing the extension of the diameter of the locking rings 6, enabling the top of the foundation 2 to be formed as part of a ball surface having a minimum ball diameter.

Fig. 1 viser endvidere, at spindelen 1 i berøringsfladen, som har kontakt 30 med toppen af fundamentet 2, er udformet komplementært til fundamentets kugleoverflade, hvorved spindel og fundament er fuldstændig tilpasset hin- DK 177182 B1 5 anden, hvilket modvirker optagelse af urenheder mellem de to understøtningskomponenter. Som det også fremgår af fig. 1, er spindelen 1 udført i et ubrudt stykke materiale, således at der ikke gennem samlinger eller lignende kan ophobes urenheder.FIG. 1 further shows that the spindle 1 in the contact surface which contacts 30 with the top of the foundation 2 is formed complementary to the spherical surface of the foundation, whereby the spindle and foundation are completely adapted to each other, which prevents the uptake of impurities between the two support components. As can also be seen from FIG. 1, the spindle 1 is made of an unbroken piece of material so that impurities cannot be accumulated through joints or the like.

Fig. 2 viser i samme snit som fig. 1 en understøtning, hvor spindelen 1 er drejet i en vinkel 10 i forhold til fundamentet 2. Drejningen af spindelen sker med centrum i punkt 11, som samtidig er midt- og centerpunkt for de to låseringe 6.FIG. 2 shows in the same section as FIG. 1 shows a support in which the spindle 1 is rotated at an angle 10 with respect to the foundation 2. The rotation of the spindle is centered at point 11, which is at the same time the center and center points of the two locking rings 6.

10 På fig. 2 er spindelen 1 drejet ud i en ydervinkel begrænset af åbningen i fundamentet 2. Af fig. 2 fremgår endvidere, at spindelen 1 er udformet således, at den også i yderpunkterne for sin bevægelse dækker åbningen i toppen af fundamentet 2. Dette betyder, at spindelen 1 frit kan bevæges i 15 alle retninger inden for de givne begrænsninger uden mulighed for indtrængning og ophobning af urenheder i konstruktionen.10 In FIG. 2, the spindle 1 is turned out at an outer angle limited by the opening in the foundation 2. From fig. 2 further shows that the spindle 1 is designed so that it also covers the opening at the top of the foundation also at the extremities of its movement. This means that the spindle 1 can move freely in all directions within the given restrictions without the possibility of penetration and accumulation of impurities in the construction.

Fig. 3 viser i et snit gennem symmetriaksen 9 i fundamentet 2 af understøtningen. Fundamentet består af det viste basismateriale 7, som er en poly-20 mer, eksempelvis en gummiblanding, der i toppen har en åbning, hvorigennem en spindel kan indstikkes og fæstnes i de i polymermaterialet integrerede låseringe 6A og 6B. Låseringene vil normalt være indstøbt i polymermaterialet.FIG. 3 is a section through the axis of symmetry 9 of the foundation 2 of the support. The foundation consists of the base material 7 shown, which is a polymer, for example a rubber mixture having an opening at the top through which a spindle can be inserted and fixed in the locking rings 6A and 6B integrated in the polymer material. The locking rings will normally be embedded in the polymeric material.

25 Punktet 11, som er midt- og centerpunkt for de to viste låseringe 6A og 6B, er samtidig centrum for bevægelsen af en spindel, som fæstnes ved indstik i låseringene.The point 11, which is the center and center point of the two locking rings 6A and 6B, is at the same time the center of movement of a spindle, which is secured by insertion into the locking rings.

Den øverste del af fundamentet 2 er forsynet med en metallisk overfladedel 30 8, som typisk er en rustfri stållegering, samt en polymerdel 13, der afsluttes i en åbning til montering af en spindel.The upper part of the foundation 2 is provided with a metallic surface portion 30 8, which is typically a stainless steel alloy, as well as a polymer portion 13 which terminates in an opening for mounting a spindle.

DK 177182 B1 6DK 177182 B1 6

Som vist på fig. 3 består åbningen øverst af en cylindrisk del 14, som er karakteristisk ved at have en mindre diameter end diameteren af spindelen, som efter indstikning omsluttes af polymerdelfladen 14. Når diameteren af polymeren er mindre end diameteren af spindelen opnås, at overgangen 5 mellem polymeren og spindelen slutter meget tæt, hvilket er vigtigt, når der stilles krav til hygiejnen.As shown in FIG. 3, the opening at the top consists of a cylindrical portion 14, which is characterized by having a smaller diameter than the diameter of the spindle, which, after insertion, is enclosed by the polymer sub-surface 14. When the diameter of the polymer is smaller than the diameter of the spindle, the transition 5 between the polymer and the the spindle ends very tightly, which is important when hygiene demands.

Af fig. 3 fremgår endvidere, at åbningen i polymeren 7 fra det cylindriske stykke 14 i retning mod låseringene 6A og 6B ændrer form, således at dia-10 meteren øges over et stykke 15 for efterfølgende igen at ændre retning, så den indre diameter af åbningen igen mindskes over et stykke 16. Når en spindel indstikkes i åbningen i polymeren og fæstnes i låseringene 6A og 6B, vil formen af polymeren vist i fig. 3 ved de ved 15 og 16 anførte delstykker danne et hulrum mellem den fæstnede spindel og polymeren 7, idet 15 spindelen er cylindrisk i området omkring fladerne 15 og 16.In FIG. 3 further shows that the opening in the polymer 7 from the cylindrical piece 14 towards the locking rings 6A and 6B changes shape so that the diameter is increased over a piece 15 to subsequently change direction again so that the inner diameter of the opening is again reduced. over a piece 16. When a spindle is inserted into the opening in the polymer and fixed in the locking rings 6A and 6B, the shape of the polymer shown in FIG. 3 at the portions indicated at 15 and 16 form a cavity between the attached spindle and the polymer 7, the 15 spindle being cylindrical in the region around the faces 15 and 16.

Hulrummet mellem polymeren og spindelen, som forårsages af fladerne 15 og 16, har den funktion, at en befæstet spindel kan bevæges uden at sammenpresse og derved potentielt skade polymeren 7.The cavity between the polymer and the spindle caused by the surfaces 15 and 16 has the function that a fastened spindle can be moved without compressing, thereby potentially damaging the polymer 7.

2020

Samtidig betyder udformningen af fladerne 15 og 16, at en i låseringene befæstet spindel kan bevæges med bibeholdt tætning af fladen 14 mod spindelen, idet hulrummet under fladen 14 bevirker, at der ikke som følge af spindelbevægelsen presses polymermateriale op nedefra, som ville kunne 25 forårsage en åbning mellem spindel og polymer med risiko for indtrængen af urenheder.At the same time, the design of the surfaces 15 and 16 means that a spindle attached to the locking rings can be moved with the sealing of the surface 14 maintained against the spindle, the cavity under the surface 14 preventing polymer material from being pressed up from below which could cause 25 an opening between the spindle and the polymer with the risk of penetration of impurities.

Fig. 4 viser i et snit i symmetriaksen 9 fundamentet af en understøtning, hvor den kugleformede del af fundamentets top er anført ved en vinkel 18.FIG. 4 shows in section in the axis of symmetry 9 the foundation of a support, the spherical part of the top of the foundation being indicated at an angle 18.

30 Kugleudsnittet har centrum i punktet 11, der også er midt- og centerpunkt for de to låseringe 6. Radius for kugleoverfladen er vist ved 17.The ball section has the center of the point 11, which is also the center and center point of the two locking rings 6. The radius of the ball surface is shown at 17.

DK 177182 B1 7DK 177182 B1 7

Med anvendelse af to låseringe 6 opnås en befæstigelseskraft af en spindel, som indstikkes i låseringene, der svarer til den kraft, som ville kunne opnås med kun én låsering med større diameter.By using two locking rings 6, a fastening force is obtained by a spindle which is inserted into the locking rings corresponding to the force which could be obtained with only one larger diameter locking ring.

5 Problemet er imidlertid, at hvis låseringsdiameteren øges, vil dette kræve, at kugleoverfladeradius også skal øges, idet forsøg har vist, at der skal være en vis mængde polymermateriale mellem låseringene 6 og den metalliske overfladedel 8, for at emnet kan produceres og fungere hensigtsmæssigt.The problem, however, is that if the locking ring diameter is increased, this will require the ball surface radius to be increased as well, experiments have shown that there must be a certain amount of polymer material between the locking rings 6 and the metallic surface portion 8 for the workpiece to be produced and function appropriately. .

1010

Det er i den forbindelse indlysende, at øget krav til radius af kugleoverfladen betyder, at understøtningen bliver fysisk større, hvilket af flere årsager, herunder pladshensyn, er uønsket, og en større maskinsko vil også kræve større materialeforbrug, hvilket vil gøre maskinskoen dyrere at fremstille og 15 dermed mindre konkurrencedygtig.In this connection, it is obvious that increased requirements for the radius of the ball surface mean that the support becomes physically larger, which for several reasons, including space considerations, is undesirable and a larger machine shoe will also require greater material consumption, which will make the machine shoe more expensive to manufacture. and 15 thus less competitive.

Netop to låseringe har vist sig at give et optimalt forhold mellem produktionsvenlighed, funktionalitet og størrelse af maskinskoen.Exactly two lock rings have been found to provide an optimal relationship between production friendliness, functionality and size of the machine shoe.

20 I praksis vil hensigtsmæssige udførelsesformer af understøtningens kugleudsnitsoverflade have en rumvinkel, der med centrum i 11 vil have en middelværdi på ca. 4,5 steradian med ydre grænseværdier, der vil ligge mellem 2,5 og 6,0 steradian.In practice, suitable embodiments of the ball cut surface of the support will have a space angle which, with the center in 11, will have a mean of approx. 4.5 steradian with external limit values that will be between 2.5 and 6.0 steradian.

25 Som det endvidere vil fremgå af fig. 4, er det karakteristisk for understøtningens fundamentdel 2, at den metalliske overfladedel, der i toppen af fundamentet udgør en del af en kugleflade som anført ved vinkel 18, hvor kugleoverfladeformen afsluttes, konvekst ændrer form, således at den metalliske overflade i et stykke 19 udgør en del af en keglestub, der har mind- 30 ste radius ved kuglefladedelen og største radius mod bunden af fundamentet.25 As will further be apparent from FIG. 4, it is characteristic of the foundation portion 2 of the support that the metallic surface portion forming at the top of the foundation a portion of a ball surface as indicated at angle 18 where the ball surface shape is terminated convexly changes shape so that the metallic surface of a piece 19 a portion of a cone stub having a minimum radius at the ball face portion and greatest radius toward the bottom of the foundation.

DK 177182 B1 8DK 177182 B1 8

Det er i den forbindelse væsentligt, at overfladen som vist ved 19 hælder fra midten af fundamentet mod randen af fundamentet, hvormed urenheder vil glide af fladen, hvilket igen har hygiejnisk betydning.In this connection, it is essential that the surface, as shown at 19, inclines from the center of the foundation towards the edge of the foundation, with which impurities will slip off the surface, which in turn has hygienic significance.

5 Selv om opfindelsen er forklaret i forbindelse med en understøtning til eksempelvis maskiner samt en fremgangsmåde til understøtning, er der intet til hinder for inden for de af patentkravene angivne rammer at anvende opfindelsens principper i andre sammenhænge.Although the invention has been explained in connection with a support for, for example, machines and a method for support, there is nothing to prevent the principles of the invention from being applied in other contexts within the scope of the claims.
