Load bolts 10 possibility to swing around the bolts 11 are delimited by the stop shoulder 12, 13. These welding bolts are divided into two parts and at the center are equipped with screw stable sleeves 14, by means of which the length of the locking bolts can be adjusted. At the lower end, the Oro bolts are formed as having vessels 15, intended to engage under the rails lugs 16. The bearing plate also has a pivotally mounted ratchet latch 17 arranged to cooperate with a barb 18, which is fixed to the bearing housing 8. A manOverarm 19 Or welded to the top 6. bearing plate.

I fig. 1 och 2 visas luckan 1 stangningslage, vilket uppnatts genom att lagerplatarna me-deist manoverarmen 19 vridits medsols. Harvid nedsankes fOrst luckan, sa att packningarna 22, som aro anordnade i spar i luckans nedatriktade kanter, komma att vila mot ramens ovre kant 23. Vid fortsatt vridning at samma hall, efter att luckan 1 kommit till anliggning pa ramen, svanges lagerplaten omkring axeln 7 i lagerhuset 8. Harvid hojes hjulet 2 upp Iran styrskenan 3, och samtidigt svanges den med lagerplaten forbundna lasbulten 10 sa, att dess nedtill utbildade hake 15 griper in under sparrklacken 16, som am fhst p6. insidan av skenan 3, varigenom luckan pressas -Mande mot ramen. Luckan 1 stoder vid sin framre ande mot ett anslag 24, som begransar luckans rorelse framat. I och med sparrbultshakarnas ingrepp under sparrklackarna 16 fixeras alltsa luckans lage i bad a riktningarna. Lagerpltitarna 6 och darigenom luckan fasthallas i last lage av sparrklinkan 17, som i lagerplatarnas resp. hjulens uppsvangda lage griper bakom mothaken. 18. Figs. 1 and 2 show the door 1 closing position, which has been achieved by turning the bearing plates by means of the control arm 19 clockwise. The door is first lowered so that the gaskets 22, which are arranged in grooves in the downwardly directed edges of the door, will rest against the upper edge 23 of the frame. When the same hall continues to rotate, after the door 1 has come into contact with the frame, the bearing plate is pivoted about the axis 7 in the bearing housing 8. Then the wheel 2 is raised up the guide rail 3, and at the same time the locking bolt 10 connected to the bearing plate is pivoted so that its lower formed hook 15 engages under the ratchet lug 16, which is fhst p6. inside of the rail 3, whereby the door is pressed -Mande against the frame. The door 1 stands at its front spirit against a stop 24, which limits the forward movement of the door. As a result of the engagement of the ratchet bolt hooks under the ratchet lugs 16, the bearing of the door is fixed in both directions. The bearing plates 6 and thereby the door are held in the load layer by the ratchet latch 17, which in the bearing plates resp. the raised bearing of the wheels grips behind the barb. 18.

Vid aterforandet av luckan till transportlage losgor man forst sparrhaken 17, vilket sker genom tryck for hand eller med en fot mot sparrklinkans pedaltinde 25, varefter manoverspaken 19 vrides motsols. Harvid sankas hjulen forst ned mot skenorna, i det lagerplaten vrides omkring axellagret 7, 8, samtidigt som lasbultarnas 10 hakar 15 svangas ut frau stoppklackarna 16. Vid fortsatt svangning kommer darefter luckan 1 att hojas fran sitt sate, i det att dess forbindningsstalle med lagerplaten beskriver en svangningsrorelse omkring hjulaxeln .5. Svangningsrorelsen fortsattes, tills axeln 7 befinner sig rakt Over eller i det narmaste rakt Over 2— - hjulaxlarna 5, i -vilket lage Indian är klar for transport, d. v. s. for tillbakaskjutning langs skenorna Iran stangningslaget. When returning the door to the transport position, the ratchet hook 17 is first released, which is done by pressure by hand or with one foot against the pedal tip 25 of the ratchet latch, after which the control lever 19 is turned counterclockwise. In this case, the wheels are first lowered towards the rails, in that the bearing plate is rotated around the shaft bearing 7, 8, at the same time as the hooks 15 of the locking bolts 10 are pivoted out from the stop lugs 16. When the pivot continues, the door 1 will be raised from its seat. describes an oscillating motion about the wheel axle.5. The oscillating motion was continued until the shaft 7 was straight Over or almost straight Over 2— - the wheel axles 5, in which layer Indian is ready for transport, i.e. for bouncing back along the rails of the Iran bar team.

Upptill aro de bada Iagerplatarna pa vardera sidan inbardes forbundna medelst forbindningsstangerna 20, vilkas langd kan justeras medelst stallskruvhylsor 21. Harigenom tvangsstyras alla lagerplatama att rara sig pa samma gang formedelst en enda manoverspak. At the top, the two bearing plates on each side are connected by means of the connecting rods 20, the length of which can be adjusted by means of stable screw sleeves 21. This forcibly controls all the bearing plates to move at the same time by means of a single control lever.

Givetvis kunna vissa konstrnktiva omformningar eller forandringar av det Tisade och beskrivna utforingsexemplet vidtagas, utan att ramen far uppfinningen darfar frangas. Salunda kan exempelvis en maskinell anordning eventuellt kombineras med luckan, som utfor lasnings- och frigoringsoperationen, i stallet f6r den far manuell drift avsedda manOverspaken. Vidare kan lagerplatsanordningen tillampas for vertikalt haugande luckor, varvid luckan hanger pa endast en skena och lophjulsantalet reduceras med halften. Viii mycket stora luckor kunna flera an tvâ par hjul Tara lampliga och vid sma luckor kunna lagerplatarna utforas sâ att endast en plat pa vardera sidan anordnas gemensam for tva. hjul. Of course, certain constructive modifications or alterations of the Tisade and described embodiments may be made without departing from the scope of the invention. Thus, for example, a mechanical device can optionally be combined with the door, which performs the loading and unloading operation, instead of the control lever intended for manual operation. Furthermore, the storage device can be applied for vertically piling doors, the door hanging on only one rail and the number of impellers being reduced by half. With very large gaps, more than two pairs of wheels can be fitted, and with small gaps the bearing plates can be designed so that only one plate on each side is arranged jointly for two. wheel.
