Abstract

An arrangement at a slide 3 movable on a guide 1 and provided with longitudinal channels 6, in order to control with rolling elements 4, which travel continuously during operation in the slide 3, the slide at the guide 1. The invention is characterised in that the slide is equipped in connection with the relevant channel 6 with a roller pathway 8 of steel tape in the form of an infinite loop with straight sections 8a, 8b adapted to the length of the slide, whereby one section 8b that faces the guide forms a bearing roller pathway under the rolling elements 4 returning from the interaction with the guide. The first section 8b is held by a spring 9 that acts between the slide 3 and the first section 8b. The continuously curved sections that join the straight sections of the roller pathway 8 extend outside of the ends of the slide and are surrounded each by a roller transfer 15 with a channel 16 open to the curved section of the roller pathway for transfer of the roller elements 4 from the first straight section to the second straight section, for the return of the rolling elements 4 following movement of the slide 3 along the guide 1.

Description

520 480 2 kanalen 6 och den andra raka delen (8a) befmner sig huvudsakligen i höjd med slidens mot gejdern vända sida. Rullbanan 8 är vid ena raka delen snett genomskuren (8c) för att möjlig- göra monteringen av rullbanan 8 i sliden 3 och för att rullarna utan störande ljud skall passera skärningen 8c. Mellan den mot gejdern vända raka delen 8b av rullbanan 8 och sliden 3 är en fjäder 9 anordnad i form av två längsgående, bomberade stålband (se närmare figur 3), vilka sträcker sig utefier hela sliden 3. Mellan rullbanan 8b och fjädern är ett distansstycke i form av ett längsgående stålband 10 anordnat (inskjutet), för att fördela fjäderkraften till raka delen 8b av rullbanan. The channel 6 and the second straight part (8a) are located substantially at the level of the side of the slide facing the guide. The roller conveyor 8 is at one straight part obliquely cut through (8c) to enable the roller conveyor 8 to be mounted in the slide 3 and for the rollers to pass the cut 8c without disturbing sound. Between the straight part 8b of the roller track 8 facing the guide and the slide 3, a spring 9 is arranged in the form of two longitudinal, bombed steel strips (see more closely Figure 3), which extend beyond the entire slide 3. Between the roller track 8b and the spring there is a spacer in the form of a longitudinal steel strip 10 arranged (inserted), to distribute the spring force to the straight part 8b of the roller conveyor.

Gejdern l uppvisar mot slidens 3 kanaler 6 svarande kanaler 12. I respektive kanals 12 botten är ett utefter gejdern sig sträckande stålband 13 inskjutet, upptaget i spår 14 anordnade i kanalen 12. Rullarna 4 kommer att löpa mellan rullbanans 8 raka del 8b och stålbandet 13 vid slidens förflyttning efter gejdem.The guide 1 has channels 12 corresponding to the channels 3 of the slide 3. In the bottom of each channel 12 a steel strip 13 extending along the guide is inserted, received in grooves 14 arranged in the channel 12. The rollers 4 will run between the straight part 8b of the roller track 8 and the steel strip 13. when moving the slide after the guide.

Vid respektive ände av sliden 3 är en rullöverföring 15, lämpligen av plast, anordnad, vilken uppvisar en kanal 16, vilken omger och är öppen mot rullbanans 8 krökta parti, vilket sträcker sig utanför slidens 3 ände. Rullarna 4 kan sålunda förflytta sig från kontakt med gejdern 1 och runt utefter rullbanans 8 krökta parti inuti kanalen 16 till att befinna sig i returrörelse mellan rullbanans del 8a och stålbandet 7 med en jämn, av rullbandet 8 styrd rörelse. Rullöverföringen 15 är försedd med en styrdel 17, vilken till formen utfyller utrymmet mellan slidens 3 ände och det utanför denna sig sträckande, krökta partiet av rullbanan 8. Genom att vid monteringen anbringa respektive rullöverföring 15 så, att styrdelen 17 sträcker sig in i nämnda utrymme, kommer de två samverkande rullöverföringarna 15 att med hjälp av styrdelarna 17 fixera rullbanan 8 och rullöverföringarna 15 inbördes och vid sliden 3. Ett lämpligt utformat lock (ej visat) låser respektive rullöverföring 15 i sidled i förhållande till sliden 3 och rullbanan 8, vilket lock lämpligen kan skruvas, limmas eller knäppas fast vid respektive rullöverföring 15.At the respective end of the slide 3 a roller transfer 15, suitably of plastic, is arranged, which has a channel 16, which surrounds and is open towards the curved portion of the roller track 8, which extends outside the end of the slide 3. The rollers 4 can thus move from contact with the guide 1 and around along the curved portion of the roller track 8 inside the channel 16 to be in return movement between the roller track part 8a and the steel strip 7 with a smooth movement, controlled by the roller belt 8. The roller transmission 15 is provided with a guide part 17, which to the mold fills the space between the end of the slide 3 and the curved portion of the roller track 8 extending outside it. By arranging the respective roller transmission 15 during assembly so that the guide part 17 extends into said space , the two cooperating roller transmissions 15 will by means of the guide parts 17 fix the roller conveyor 8 and the roller transmissions 15 to each other and to the slide 3. A suitably designed lid (not shown) locks the respective roller transmission 15 laterally relative to the slide 3 and the roller conveyor 8, which lid can be suitably screwed, glued or fastened to the respective roller transmission 15.

Det skall underförstås att slid och gejder kan ha annan tvärsnittsform än den här visade och ett armat antal och en annan placering av de längsgående kanalerna. Likaså skall det underförstås att istället för rullar 4 kan kulor användas.It is to be understood that slides and guides may have a different cross-sectional shape than that shown here and a different number and location of the longitudinal channels. It should also be understood that instead of rollers 4, bullets can be used.

För att minska rullarnas 4 friktion i slidens 3 respektive kanal 12, liksom minska ljudnivån från rullarna vid drifi, kan längsgående sidostöd 18 av plast anbringas på vardera sidan i gejderns 1 i respektive kanal 12 (se figur 3), vilka sidostöd 18 lämpligen är styrda med hjälp av utåtriktade vulster ingripande i sidospår hos kanalen 12. En ytterligare åtgärd är att anbringa distansstycken av plast mellan rullkropparna.To reduce the friction of the rollers 4 in the slide 3 and channel 12, respectively, as well as to reduce the sound level from the rollers at drive fi, longitudinal side supports 18 of plastic can be fitted on each side of the guide 1 in the respective channel 12 (see figure 3), which side supports 18 are suitably controlled by means of outwardly directed beads engaging in side grooves of the channel 12. A further measure is to place plastic spacers between the roller bodies.
