Den foreliggende opfindelse angår en indretning til aftagelig fastsætning af en stolpe til et lastbi 11 ad samt en fjæl eller lignende til opstanderen, hvilken indretning i det mindste omfatter et første og i det mindste et andet på stolpen forskydeligt anbragt låseorgan, som er 5 tilvejebragt for at gå i indgreb med ladet henholdsvis fjælen og som betjenes af et fra stolpens yderside tilgængeligt håndtag.BACKGROUND OF THE INVENTION The present invention relates to a device for removably attaching a post to a cargo side 11 ad and a bar or the like to the upright, which device comprises at least a first and at least a second locking member displaceably provided on the post, provided for to engage the load and the bar, respectively, and which is operated by a handle available from the outside of the post.

Indretninger af ovennævnte slags er tidligere kendt, for eksempel fra de svenske patentskrifter 218 048, 320 275 og 7312593-2. Disse indret-10 ni nger er behæftet med flere ulemper, af hvilke den nok største er at opstanderen, når kun fjælen skal frigøres fra opstanderen, til tider også, i det mindste delvis frigøres fra ladet, hvilket kan forårsage store problemer. Andre ulemper er, at der opstår slør mellem håndtag og låseorgan, hvilket gør indretningen mindre pålidelig, og at håndta-15 get hurtigt kan svinge mod en åben fra opstanderen fremspringende stilling og derved forårsage personskader, hvilken svingning tilvejebringes, da der skal anvendes en kraftig fjeder til at holde håndtaget i en lukket excenterlåsestil ling. En yderligere ulempe er, at der kræves en stor kraft for at frigøre låseorganerne fra opstanderen og/eller 20 fjælen, hvis lasten på lastbi Hadet udøver et stort tryk mod disse.Devices of the above kind are previously known, for example from Swedish Patent Specifications 218 048, 320 275 and 7312593-2. These devices have several drawbacks, the greatest of which is that the riot, when only the bar is to be released from the riot, is sometimes also at least partially released from the charge, which can cause major problems. Other disadvantages are that gaps occur between the handle and the locking member, which makes the device less reliable, and that the handle can quickly swing towards an open position protruding from the upright, thereby causing personal injury, which oscillation is provided, since a strong use is required. spring to hold the handle in a closed eccentric lock position. A further disadvantage is that a large force is required to release the locking means from the upright and / or the bar if the load on the load bee exerts a great pressure on them.

Det er formålet med den foreliggende opfindelse, at overvinde ulemperne ved tidligere kendte indretninger af omtalte type, og at tilvejebringe en indretning som dels sikrer at fjælen frigøres fra opstande-25 ren inden opstanderen frigøres fra ladet, dels er pålidelig og enkel at betjene og dels indtager præcise, stabile stillinger såvel når indretningen fastlåser opstanderen og fjælen som når den er ført ud af indgreb med disse.It is the object of the present invention to overcome the disadvantages of prior art devices of the type mentioned and to provide a device which partly ensures that the bar is released from the upriver before the upriver is released from the load, partly reliable and easy to operate and partly occupies precise, stable positions both when the device locks the upright and the shaft as well as when it is disengaged.

30 Dette formål opfyldes ved at indretningen, ifølge den foreliggende opfindelse, er bibragt de i patentkravene angivne kendetegn.This object is fulfilled by providing the device according to the present invention with the characteristics specified in the claims.

Opfindelsen vil herefter blive forklaret nærmere under henvisning til den medfølgende tegning, hvor 35 fig. 1 viser et længdesnit gennem en opstander forsynet med indretningen ifølge opfindelsen, hvilken indretning indtager en 1 åsestil1ing for såvel opstander som fjæl, fig. 2 et længdesnit taget vinkelret i forhold til snittet i fig. 1The invention will now be explained in more detail with reference to the accompanying drawing, in which: FIG. 1 shows a longitudinal section through an upright provided with the device according to the invention, which occupies a ridge position for both upright and ridge; FIG. 2 is a longitudinal section taken perpendicular to the section of FIG. 1

10 På tegningen er der vist en lodret yderkant af et lad 1 på en lastbil ved hvilket lad en opstander 2 er aftageligt fastgjort. Ladet 1 er forsynet med en krog la og en bøjle lb som samvirker med opstanderen samt en til denne fastgjort første låseindretning. Opstanderen er endvidere forsynet med en anden lukkeindretning, der er beregnet til en 15 aftagelig forbindelse med opstanderen og en fjæl 3, som med bøjleformede dele, (af hvilke én 3a er vist) er indført i opstanderen. Begge låseindretningerne betjenes ved hjælp af et ved opstanderen anbragt håndtag 4.10 The drawing shows a vertical outer edge of a drawer 1 on a truck to which a drawer 2 is detachably attached. The drawer 1 is provided with a hook 1a and a hanger 1b which cooperate with the upright and a first locking device attached thereto. The upriver is further provided with a second closure device which is intended for a removable connection with the upright and a bar 3, which with hanger-shaped parts (one of which 3a is shown) is inserted into the upright. Both locking devices are operated by means of a handle 4 arranged by the upright.

20 Opstanderen 2 er forsynet med to indre forstærkningsplader 2b og 2c og en forstærkningsplade 5, der ligger an mod ladets kant og hvis nedre kant 5a er indført mellem ladets kant og krogen la, således at opstanderen ikke vil kunne forskydes vandret i forhold til ladet. I denne stilling hviler en nedre vandret underdel af opstanderen mod oversiden 25 af krogen la.The upright 2 is provided with two inner reinforcing plates 2b and 2c and a reinforcing plate 5 abutting the edge of the drawer and whose lower edge 5a is inserted between the edge of the drawer and the hook 1a, so that the upright will not be displaced horizontally relative to the drawer. In this position, a lower horizontal lower part of the upright rests on the upper side 25 of the hook 1a.

Den første låseindretning til aftagelig fastholdelse af opstanderen 2 ved ladet 1 omfatter en langstrakt kile 6, som er forskydelig ind i og ud af bøjlen lb, der passerer gennem et hul 5b i pladen 5. Kilen 6 er 30 forsynet med to arme 6a og 6b samt en plade 6c, der forbinder disse.The first locking device for detachable retention of the upright 2 by the load 1 comprises an elongate wedge 6 which is slidable in and out of the hoop 1b passing through a hole 5b in the plate 5. The wedge 6 is provided with two arms 6a and 6b as well as a plate 6c connecting them.

En aksel 7 strækker sig imellem og er fastgjort til armene 6a og 6b. Håndtaget 4 er drejeligt lejret på akslen 7.A shaft 7 extends in between and is attached to the arms 6a and 6b. The handle 4 is rotatably mounted on the shaft 7.

Den anden låseindretning for udløselig fastholdelse af fjælen 3 ved 35 opstanderen 2 omfatter to stifter 8 og 9, der kan forskydes ind i og ud af fjælbøjlerne 3a, når fjælen er slået op og ligger an mod stolpen. Stifterne 8 og 9 er forbundet med hinanden ved hjælp af en stang 10, der styres for en bevægelse i opstanderens længderetning. Stangen 10 er tillige forbundet med et pladejern 11 som styres for en bevægelse iThe second locking device for releasably retaining the bar 3 by the upright 2 comprises two pins 8 and 9 which can be slid into and out of the bar clips 3a when the bar is opened and abuts against the post. The pins 8 and 9 are connected to each other by a rod 10 which is controlled for a longitudinal movement of the upright. The rod 10 is also connected to a plate iron 11 which is controlled for movement in

opstanderens længderetning ved hjælp af dele 11a, som er beliggende mellem opstanderens inderside og udskæring 6d i den langstrakte kile 6 (se fig. 3) og som er forsynet med to ører 12 og 13, der er forbundne med hinanden ved hjælp af en aksel 14. Den ene ende af en svingarm 15 5 med U-formet tværsnit er drejeligt lejret på akslen 14. Svingarmens anden ende er drejeligt lejret på en aksel 16, som er gjort fast på det med U-formet tværsnit udformede håndtag 4. En skruefjeder 21 er viklet omkring akslen 14 og er forsynet med en armdel 21a som er indført i en lomme på svingarmen 15's inderside samt en armdel 21b, der 10 er i anlæg mod pladejernet 11 mellem ørerne 12 og 13.longitudinal direction of the upright by means of portions 11a located between the inside of the upright and cut-out 6d of the elongated wedge 6 (see Fig. 3) and provided with two ears 12 and 13 connected by a shaft 14 One end of a swivel arm 15 with a U-shaped cross section is pivotally mounted on the shaft 14. The other end of the swivel arm is pivotally mounted on a shaft 16 which is secured to the handle 4 with the U-shaped cross section. A coil spring 21 is wrapped around the shaft 14 and is provided with an arm portion 21a which is inserted into a pocket on the inside of the pivot arm 15 and an arm portion 21b which abuts against the plate iron 11 between the ears 12 and 13.

En spærrekrog 17 som er drejeligt lejret centralt på akslen 17 er forsynet med en næse 17b, der er beregnet til indgreb med en knast 18, som er fastgjort på stolpen 2's inderside. Spærrekrogen tvinges med 15 uret omkring akslen 7 af en skruefjeder 19, der er viklet omkring akslen 16 og hvis ene armdel 19a er i anlæg mod akslen 7 og hvis anden armdel 19b er i anlæg mod en tap 17a, som er fastgjort til spærrekrogen 17.A locking hook 17 pivotally mounted centrally on the shaft 17 is provided with a nose 17b intended for engagement with a cam 18 secured to the inside of the post 2. The locking hook is forced clockwise around the shaft 7 by a coil spring 19 wound around the shaft 16 and whose one arm portion 19a abuts against the shaft 7 and the other arm portion 19b abuts against a pin 17a attached to the locking hook 17.

20 Indretningens funktion vil herefter blive beskrevet, idet det antages at opstanderen 2 er fastlåst ved ladet 1 og at en fjæl 3 er fastlåst til opstanderen, det vil sige, at indretningens dele indtager de i fig. 1 og 2 viste stillinger.The operation of the device will then be described, assuming that the upright 2 is locked at the load 1 and that a bar 3 is locked to the upright, that is, the parts of the device occupy those of FIG. 1 and 2.

25 Når fjælen 3 skal frigøres fra opstanderen 2, det vil sige, når den anden låseindretning skal frigøres, løftes håndtaget 4, der befinder sig indenfor opstanderens ydre begrænsning fra den i fig. 1 viste stilling, hvor akslen 16 befinder sig til højre for en forbindelseslinie mellem akslerne 7 og 14, og hvor den ved indvirkning dels fra en tryk-30 fjeder 20, som virker mellem stangen 10 og en del 2a af stolpen og som trykker stangen 10 i retning mod ladet 1 og dels af fjederen 21, som presser svingarmen 15 mod uret omkring akslen 14 og som bibeholdes i en excenterlåsestil ling. Ved håndtagets løftning passerer akslen den nævnte forbindelseslinie imod indvirkning af kraften fra fjedrene 20 35 og 21 og flyttes i retning væk fra opstanderen. Kraften i fjederen 20 og tyngden af den anden låseindretning 8, 9, 10, 11, o.s.v. medfører at stifterne 8, 9 samtidig forskydes et stykke nedefter i figurerne 1 og 2. For at forskyde stifterne yderligere nedefter og helt ud af indgreb med bøjlerne 3a, svinges håndtaget 4 yderligere mod uret omkring 4When the bar 3 is to be released from the upright 2, that is, when the second locking device is to be released, the handle 4 which is within the external limitation of the upright is lifted from the one shown in FIG. 1, where the shaft 16 is to the right of a connecting line between the shafts 7 and 14, and where it acts, partly from a spring 30, which acts between the rod 10 and a part 2a of the post and which pushes the rod 10 in the direction of the load 1 and partly of the spring 21 which pushes the pivot arm 15 counterclockwise around the shaft 14 and which is maintained in an eccentric locking position. Upon lifting of the handle, the shaft passes said connecting line against the action of the force of the springs 20 35 and 21 and is moved in a direction away from the upright. The force of the spring 20 and the weight of the second locking device 8, 9, 10, 11, etc. causes the pins 8, 9 to be simultaneously displaced downwardly in Figures 1 and 2. In order to further shift the pins downwards and completely out of engagement with the shackles 3a, the handle 4 is further pivoted counterclockwise about 4

akslen 7 mod den i fig. 3 viste stilling, hvorved svingarmen 15, mod fjederen 21's indvirkning, svinges med uret omkring akslen 14 og medfører ørerne 12, 13, pladejerne 11, stangen 10 og stifterne nedefter i fig. 1. Selvom en last på ladet 1 presser kraftigt mod fjælen 3 og/el-5 ler opstanderen 2 og besværliggør udtrækningen af stifterne 8, 9, tvinges stifterne ud af indgreb med fjælbøjlerne 3a inden kilen 6 forskydes, eftersom spærrekrogen 17's næse 17b er i anlæg mod knasten 18 og forhindrer akslen 7's og dermed kilens forskydning opefter i fig. 1.shaft 7 against the one shown in FIG. 3, against the action of the spring 21, the pivot arm 15 is pivoted clockwise around the shaft 14 and causes the ears 12, 13, the plate nuts 11, the rod 10 and the pins downwards in FIG. 1. Although a load on the load 1 presses forcefully against the bar 3 and / or 5, the upright 2 makes the pulling of the pins 8, 9 difficult, the pins are forced out of engagement with the bar shackles 3a before the wedge 6 is displaced, since the lock 17 of the locking hook 17 abutting the cam 18 and preventing the shaft 7 and thus the wedge displacement upwards in FIG. First

10 Når stifterne 8, 9 er trukket helt ud af fjælbøjlerne 3a, hvilket sker, når håndtaget 4 er drejet mod uret omkring akslen 7 i en lille vinkel fra den i fig. 3 viste stilling og når der tillige ønskes at åbne den første låseindretning (kilen 6) drejes håndtaget 4 yderligere mod uret, hvorved tillige spærrekrogen 17 af håndtaget drejes mod uret omkring 15 akslen 7, eftersom denne under drejningsbevægelsen med en nedre inderkant 4a presser mod en anden næse 17c på spærrekrogen. Spærrekrogen føres således væk fra sit indgreb med knasten 18 mod fjederen 19's indvirkning og en fortsat drejning af håndtaget mod uret medfører at kilen 6 forskydes opefter, når pladejernet 11 kommer i anlæg mod den 20 øvre kant af knasten 18 og forhindrer fortsat nedadrettet bevægelse af den anden låseindretning (stifterne 8, 9).10 When the pins 8, 9 are completely pulled out of the mounting brackets 3a, which happens when the handle 4 is rotated counterclockwise around the shaft 7 at a slight angle from the one shown in FIG. 3, and when it is also desired to open the first locking device (key 6), the handle 4 is further rotated counterclockwise, whereby the locking hook 17 of the handle is rotated counterclockwise around the shaft 7, since during the rotational movement with a lower inner edge 4a it presses against a second nose 17c on the locking hook. The locking hook is thus moved away from its engagement with the cam 18 against the action of the spring 19 and a continued rotation of the handle counterclockwise causes the wedge 6 to shift upward as the plate iron 11 engages the upper 20 edge of the cam 18 and prevents continued downward movement of the cam 18. second locking device (pins 8, 9).

I fig. 4 vises håndtaget 4 ført til sin yderstilling mod uret, hvorved kilen 6 er trukket helt ud af bøjlen lb. Denne stilling er stabil, ef-25 tersom fjederen 21 udøver en trykkraft mod den med håndtaget forbundne svingarm 15, og håndtaget er tilstrækkelig tungt til, at det skal presses mod uret omkring akslen 7. Når låseindretningerne indtager de i fig. 4 viste stillinger, kan opstanderen fjernes fra ladet 1, ved at opstanderen først drejes mod uret omkring krogen la og derefter løftes 30 væk fra denne, når bøjlen lb ikke længere befinder sig i hullet 5b.In FIG. 4, the handle 4 is shown led to its outer position counterclockwise, whereby the wedge 6 is pulled completely out of the hanger 1b. This position is stable since the spring 21 exerts a compressive force against the pivot arm 15 associated with the handle, and the handle is sufficiently heavy for it to be pressed counterclockwise around the shaft 7. When the locking devices occupy the locking means shown in FIG. 4, the upright can be removed from the load 1 by first turning the upright counterclockwise around the hook 1a and then lifting it 30 away from it when the hoop 1b is no longer in the hole 5b.

Opstanderen 2's fastlåsning til ladet 1, og fjælen 3's fastlåsning til opstanderen sker på en måde, som er omvendt den ovenfor beskrevne og beskrivelse heraf skulle således ikke være nødvendig.The locking of the upright 2 to the drawer 1 and the locking of the bar 3 to the upright are carried out in a manner which is contrary to the above described and description thereof should not be necessary.
