Figur 8 visar i större skala ett snitt efter linjen VIII-VIII i figur 7.Figure 8 shows on a larger scale a section along the line VIII-VIII in Figure 7.

Hyllstället som visas i figur 1 innefattar en central pelare l vilken uppbäres av ett stativ eller en fot 2. Den centrala pelaren l bär flera ovanför varandra belägna cirkulära hyllor eller hyllplan 3 som är individuellt roterbara runt pelaren 1.The shelf stand shown in figure 1 comprises a central pillar 1 which is supported by a stand or a foot 2. The central pillar 1 carries several superimposed circular shelves or shelves 3 which are individually rotatable around the pillar 1.

Varje hyllplan 3 består av flera i huvudsak cirkelsektorformade hyllsektioner eller fack 4 anordnade förskjutbara på armar 5 som skjuter ut från en på den centrala pelaren 1 roterbart anordnad hållare 6. Facken är försedda med en hylsliknande del 7 som är teleskopiskt trâdd över den tillhörande armen 5 och lagrad på ett stödhjul 8 (figur 4) så att facket 4 kan förskjutas mellan ett helt inskjutet läge och ett utdraget läge. Armarna 5 lutar snett nedåt så att varorna på hyllan, utan att facket behöver dragas ut, glider mot framkanten. Om detta ej sker eller vid s22 351 påfyllning av varor på hyllan är det nödvändigt att kunna draga ut facket, se figur 2 där ett fack 4 visas utdraget.Each shelf 3 consists of several substantially circular sector-shaped shelf sections or compartments 4 arranged slidably on arms 5 projecting from a holder 6 rotatably arranged on the central column 1. The compartments are provided with a sleeve-like part 7 which is telescopically threaded over the associated arm 5 and mounted on a support wheel 8 (Figure 4) so that the compartment 4 can be moved between a fully retracted position and an extended position. The arms 5 tilt obliquely downwards so that the goods on the shelf, without the compartment having to be pulled out, slide towards the front edge. If this does not happen or when filling goods on the shelf, it is necessary to be able to pull out the compartment, see figure 2 where a compartment 4 is shown pulled out.

Utdragningen av facken 4 i hyllstället 1 begränsas på i och för sig känt sätt exempelvis av en på armarna 5 anordnad stoppskruv vilken löper i ett spår i fackets 4 hylsa 7 (ej visat).The extraction of the compartments 4 in the shelf stand 1 is limited in a manner known per se, for example by a stop screw arranged on the arms 5 which runs in a groove in the sleeve 7 (not shown) of the compartment 4.

Eftersom facken är lutande måste de emellertid vid inskjutet läge spärras av en spärranordning vilken är lätt manövrerbar från fackens yttre kant. Tidigare har spärrorgan anordnats vid fackets bakre, mot hàllaren 6 vända kant och detta spärrorgan har påverkats med en friliggande arm anordnad under facket 4, vilken arm inverkat på mellanrummet, mellan facken.However, since the compartments are inclined, they must be locked in the retracted position by a locking device which is easily operable from the outer edge of the compartments. Previously, locking means have been arranged at the rear edge of the compartment, facing the holder 6, and this locking member has been actuated with an exposed arm arranged below the compartment 4, which arm has acted on the space between the compartments.

Enligt uppfinningen är i stället anordnat en långsträckt bladformad spärrarm eller ~hake 9, som visas i figur 3-5 och som löper i en på fackets 4 översida utformad kanal 10 som ansluter till hylsan 7 och som bildas av en inverterad U-formad plåt ll som är fäst, såsom svetsad, till ovansidan av fackets 4 botten väsentligen centralt i facket. Kanalen 10 är endast så mycket bredare än spärrhakens 9 tjocklek att denna med litet spel till kanalens 10 sidor kan röra sig fritt i kanalen, medan ett större spel i höjdled medger att spärrhaken 9 kan bringas i och ur ingrepp med ett låsbleck 12 på hyllans 4 framsida.According to the invention, an elongate blade-shaped locking arm or hook 9 is provided instead, which is shown in Figures 3-5 and which runs in a channel 10 formed on the upper side of the compartment 4 which connects to the sleeve 7 and which is formed by an inverted U-shaped plate 11 which is attached, such as welded, to the top of the bottom of the compartment 4 substantially centrally in the compartment. The channel 10 is only so much wider than the thickness of the ratchet 9 that it can move freely in the channel with little play to the sides of the channel 10, while a larger play in height allows the ratchet 9 to be brought into and out of engagement with a locking plate 12 on the shelf 4 front.

För det ändamålet är spärrhaken 9 vid sin inre ände lagrad på en tapp 13 fäst i det inre av armen 5_sâ att spärrhaken kan svänga i höjdled när den yttre hakformade delen av spärrhaken 9 griper över blecket 12 och låser facket 4 i - inskjutet läge. Spärhakens 9 ytterände är för detta ändamål rundad så att spärrhaken 9 lyfts då den träffar blecket 12 och av tyngdkraften faller ned med en urtagning 14 över blecket 12. vid utförandet enligt figurerna 6-8 är en spärrhake 15 vilken med en uppvinklad del l5a är lagrad vid en tapp 5294351 l3a i armen 5, motsvarande tappen 13 i figur 4, anordnad platt mot fackets 4 undersida i en kanal 16 som bildas av en U-formad plåt 17 vilken är fäst ex.vis svetsad till nämnda undersida även här väsentligen centralt i facket. I detta fall föreligger endast ett litet spel mellan spärrhaken 15 och kanalens 16 sidor eftersom spärrhaken 15 endast skall vara fritt rörlig i kanalens 16 längdriktning när facket 4 drages ut. Sålunda spärras facket 4 i inskjutet läge av en låsregel 20 som är fäst vid fackets framsida och som med en avböjd del 18 ingriper i en urtagning 19 i spärrhaken 15 vid inskjutet fack. Låsregeln 20 är utförd av ett fjädrande material och är belastad mot det visade låsläget men kan bringas ur ingrepp med spärrhakens 15 urtagning 19 medelst en manöverarm 21 då facket 4 skall dragas ut.For this purpose, the pawl 9 is mounted at its inner end on a pin 13 attached to the interior of the arm 5 so that the pawl can pivot vertically when the outer hook-shaped portion of the pawl 9 engages the plate 12 and locks the compartment 4 in the retracted position. The outer end of the pawl 9 is for this purpose rounded so that the pawl 9 is lifted when it hits the plate 12 and falls down by gravity with a recess 14 over the plate 12. in the embodiment according to Figures 6-8 is a pawl 15 which is mounted with an angled part 15a at a pin 5294351 13a in the arm 5, corresponding to the pin 13 in figure 4, arranged flat against the underside of the compartment 4 in a channel 16 which is formed by a U-shaped plate 17 which is attached eg welded to said underside also here substantially centrally in the union. In this case there is only a small clearance between the pawl 15 and the sides of the channel 16 since the pawl 15 should only be freely movable in the longitudinal direction of the channel 16 when the compartment 4 is pulled out. Thus, the compartment 4 is locked in the retracted position by a locking latch 20 which is attached to the front of the compartment and which with a deflected part 18 engages in a recess 19 in the latch 15 at the retracted compartment. The locking bolt 20 is made of a resilient material and is loaded against the locking position shown, but can be brought out of engagement with the recess 19 of the pawl 15 by means of an operating arm 21 when the compartment 4 is to be pulled out.

Det framgår av ovanstående att utförandet med en bladformad spärrhake 9, 15 som är lagrad i en smal kanal 10, 16 ovanpå eller under facket 4 inte bygger på fackets höjd utan att avståndet mellan hyllplanen 3 kan anpassas helt efter höjden på de varor som skall lagras på hyllorna.It appears from the above that the design with a leaf-shaped pawl 9, 15 which is stored in a narrow channel 10, 16 above or below the compartment 4 is not based on the height of the compartment but that the distance between the shelves 3 can be adjusted completely to the height of the goods to be stored. on the shelves.

Då facken 4 skall dragas ut, ex.vis för påfyllning av varor, lyfts spärrhaken 9 ur ingreppet med låsblecket 12, se figur 4, eller bringas làsregeln 20 ur ingreppet med urtagningen 19, se figur 7, så att facket frigörs. Då facken 4 på nytt skjuts in kommer spärrhaken 9 resp. 15 i ingrepp med låsblecket 12 resp. làsregeln 20 så att facken är låsta i sina normala användningslägen. Genom att spärranordningarna är anordnade vid fackens framkant blir funktionen enkel och säker.When the compartments 4 are to be pulled out, eg for filling goods, the catch hook 9 is lifted out of the engagement with the locking plate 12, see figure 4, or the locking bolt 20 is brought out of the engagement with the recess 19, see figure 7, so that the compartment is released. When the compartments 4 are pushed in again, the pawl 9 resp. 15 in engagement with the locking plate 12 resp. the locking bolt 20 so that the compartments are locked in their normal positions of use. Because the locking devices are arranged at the front edge of the compartments, the function becomes simple and safe.

Det är klart att uppfinningen ej är begränsad till de visade och beskrivna utföringsformerna utan att ändringar kan göras för att anpassa spärranordningen till andra utföranden av hyllställ och förvaringsfack än de visade.It is clear that the invention is not limited to the embodiments shown and described, but that changes can be made to adapt the locking device to other embodiments of shelf racks and storage compartments than those shown.
