Abstract

Connected to the footplate of the equipment is a four-sided casing (4) which is open at least at its upper end, and receives the foot end (2) of a replaceable road marker (1), which is inserted with the foot end in the upper open end of the casing. The casing (4) has a first horizontal pivot joint (5) in its central part. The foot plate has a pair of bearing units (8) for a shaft pin (9) belonging to the pivot joint (5). A first lock (15) normally maintains the casing and the road marker raised in the vertical position, and is located in the lower end of the casing. A second lock unit (28), working in conjunction with the first, is fitted on or in the foot plate on opposite sides of the first lock. Springs activate either of the two locks.

BESKRIVNING Av FÖREDHAGEN UTFÖRINGSFQRM I Pig. 1 betecknas ett vägmärke med siffran 1. En fotände 2 på väg- märket 1 är monterad i en fotplatta 3. Fotänden 2 har på i och för sig känt sätt kvadratisk tvärsektion med dimensionen 40x40 mm och fot- plattan 3 är försedd med en hondel för att kunna ta emot fotänden 3, som sticks in i hondelen. Denna grundprincip är i och för sig känd och det nya ligger i konstruktionen av hondelen och tillhörande mekanism, som gör det möjligt att vika vägmärket 1 utan att några delar i mekanismen skadas.DESCRIPTION OF THE PREPARED EMBODIMENT IN FIG. 1 denotes a road sign with the number 1. A foot end 2 on the road sign 1 is mounted in a foot plate 3. The foot end 2 has in a manner known per se square cross section with the dimension 40x40 mm and the foot plate 3 is provided with a female part for to be able to receive the foot end 3, which is inserted into the female part. This basic principle is known per se and the novelty lies in the construction of the female part and associated mechanism, which makes it possible to fold the road sign 1 without damaging any parts of the mechanism.

Enligt uppfinningen utgörs hondelen av en fyrkanthylsa 4, som är öppen i båda ändar och har en längd av ca 150 mm. Hylsan 4 är ledbart för- bunden med fotplattan 3 genom en horisontell led, som har allmänt betecknats 5, Fig. 2 och 3. I fotplattan 3 ingår enligt en tänkbar utföringsform en bottenplåt 6, som är täckt av en ovanplatta 7, Pig. 1. Oxanplattan 7 har avlägsnats i Fig. 2 och 3. På bottenplattan 6 finns ett par lagerbockar 8 för en axeltapp 9 som bildar vridningsaxel i nämnda led 5. Axeltappen 9 sträcker sig horisontellt genom hylsan 4, genom cirkulära öppningar 10 i ett par av dennas motstående sidor ll.According to the invention, the female part consists of a square sleeve 4, which is open at both ends and has a length of about 150 mm. The sleeve 4 is hingedly connected to the foot plate 3 by a horizontal joint, which has been generally designated 5, Figs. 2 and 3. According to a possible embodiment, the foot plate 3 includes a bottom plate 6, which is covered by a top plate 7, Figs. The ox plate 7 has been removed in Figs. 2 and 3. On the bottom plate 6 there are a pair of bearing brackets 8 for a shaft journal 9 which form a pivot axis in said joint 5. The shaft pin 9 extends horizontally through the sleeve 4, through circular openings 10 in a pair of its opposite sides ll.

Hylsan 4 har en övre öppning 12 och en nedre öppning 13. Inuti hylsan 4, i dennas nedre del, finns i området för den nedre öppningen 13 ett första låsdon i form av en rulle 15, som företrädesvis är tillverkad av styv plast. Bullen 15 är vridbar omkring en nedre, andra vridnings- 10 15 20 25 30 35 _ 460 e75 axel, som bildas av en andra axeltapp 16. Denna sträcker sig genom rullen 15, parallellt med den'första axeltappen 9. Medan den första axeltappen 9 är anordnad ungefär mitt på hvlsan 4 är den undre axel- tappen 16 anordnad nära hylsans nedre ände och sträcker sig genom långsträokta öppningar 17 i hylsans sidor 11. I normalläge anligger axeltappen 16 mot nedre änden på öppningarna eller spåren 17.The sleeve 4 has an upper opening 12 and a lower opening 13. Inside the sleeve 4, in its lower part, there is in the area of the lower opening 13 a first locking device in the form of a roller 15, which is preferably made of rigid plastic. The ball 15 is rotatable about a lower, second axis of rotation 460 e75 axis, which is formed by a second axle pin 16. This extends through the roller 15, parallel to the first axle pin 9. While the first axle pin 9 is arranged approximately in the middle of the sleeve 4, the lower shaft pin 16 is arranged near the lower end of the sleeve and extends through elongate openings 17 in the sides 11 of the sleeve. In normal position the shaft pin 16 abuts against the lower end of the openings or grooves 17.

Rullen 15 är vidare monterad på ett par bärarmar 18, en på vardera sidan om rullen. Bärarmarna 18 är försedda med ett cirkulärt hål 19 i nedre änden och ett långsträckt hål 20 i övre änden. Det nedre hålet 19 har samma storlek som den nedre axeltappen 16, medan det övre hålet eller spåret 20 har samma form och längd som spåret 17 i vardera hylssidan 11.The roller 15 is further mounted on a pair of support arms 18, one on each side of the roller. The support arms 18 are provided with a circular hole 19 at the lower end and an elongate hole 20 at the upper end. The lower hole 19 has the same size as the lower shaft pin 16, while the upper hole or groove 20 has the same shape and length as the groove 17 in each sleeve side 11.

Mellan bärarmarna 18 finns ovanför rullen 15 en tvärslå 21. På ett avstånd över tvärslån 21 finns en bygel 22 med ett horisontellt liv 23, som är beläget under den första axeltappen 9, då hylsan 4 har intagit vertikalt läge, och ett par vertikala skänklar 24. Dessa är försedda med cirkulära hål 25 med samma diameter som axeltappen 9 och hålen 10 i hylsans sidor 11. Axeltappen 9 är trädd genom även dessa hål 25. Räknat från den ena sidan till den andra är axeltappen 9 alltså trädd genom ett första hål 10 i en av hylsans sidor ll, genom spåret 20, genom det första hålet 25 i den första skänkeln 24, genom det andra hålet 25 i den andra skänkeln 24, genom det andra spåret 20 i den högra bärarmen 18 och slutligen genom det andra hålet 10 i_den högra sidan 11 på hylsan 4.Between the support arms 18 there is above the roller 15 a transverse bar 21. At a distance above the transverse bar 21 there is a bracket 22 with a horizontal web 23, which is located below the first shaft pin 9, when the sleeve 4 has assumed a vertical position, and a pair of vertical legs 24 These are provided with circular holes 25 with the same diameter as the shaft pin 9 and the holes 10 in the sides 11 of the sleeve. The shaft pin 9 is threaded through also these holes 25. Counted from one side to the other, the shaft pin 9 is thus threaded through a first hole 10. in one of the sides 11 of the sleeve, through the groove 20, through the first hole 25 in the first leg 24, through the second hole 25 in the second leg 24, through the second groove 20 in the right support arm 18 and finally through the second hole 10 i_the right side 11 of the sleeve 4.

Mellan tvärslån 21 och hylsans 22 liv 23 finns ett par gummikutsar 26, som fungerar som kompressionsfjädrar. I normalläge strävar fjädrarna 26 att pressa hylsan 22 och tvärslån 21 från varandra. Krafterna över- förs till axeltapparna 9 och 16 via skänklarna 24 respektive bärarmar- na 18, så att den övre axeltappen 9 pressas upp mot spårens 20 övre ände och axeltappen 16 pressas ned mot spårens 17 nedre ände.Between the cross member 21 and the body 23 of the sleeve 22 there are a pair of rubber pads 26, which act as compression springs. In the normal position, the springs 26 strive to press the sleeve 22 and cross member 21 apart. The forces are transmitted to the shaft pins 9 and 16 via the legs 24 and the support arms 18, respectively, so that the upper shaft pin 9 is pressed up against the upper end of the grooves 20 and the shaft pin 16 is pressed down towards the lower end of the grooves 17.

Dessa upphöjningar 28 är långsträckta och parallella med rullen 15 mot plåten 6 mellan de båda upphöjningarna 28, som anligger mot rullens 15 mantel, vilket illustreras genom de streckade detal- jerna i Fig. 2. Upphöjningarna 28 utàör härvid andra låsdon, som sam- verkar med det första låsdonet, som utgörs av rullen 15.Between the bearing brackets 8 there are a pair of parallel elevations 28 on of, «m ... ~ ...., -» -----.

These elevations 28 are elongate and parallel to the roller 15 against the plate 6 between the two elevations 28, which abut against the casing of the roller 15, as illustrated by the dashed details in Fig. 2. The elevations 28 here perform other locking device, which cooperates with the first locking device, which consists of the roller 15.

Normalt håller upphöjningarna 28 vägmärket 1 i vertikalt läge, genom att fjädrarna/gummikutsarna 26 ger en tillräcklig inspänningskraft för att hindra rullen 15 att rulla förbi upphöjningarna 28 åt endera hållet. Om emellertid vägmärket 1 påköres eller utsätts för annan ~ 'f onormal påkänning kan fjädrarnas 26 fjäderkrafter övervinnas. Fjäd- rarna 26 komprimeras härvid, varvid rullen 15 rullar förbi en av upphöjningarna 28, varvid den nedre axeltappen 16 lyfts upp i spåren 17 och bärarmarna 18 lyfts uppåt, varvid den övre axeltappen 9;'som är fast relativt hylsan 4, utför en relativrörelse i spåren 20 under komprimering av fjädrarna/gummikutsarna 26. Samtidigt vrids hela hylsan 4 i leden 5, dvs omkring den övre axeltappen 9. Så snart rullen 15 har passerat endera av upphöjningarna 28 återgår rullen 15 med hjälp av fjädrarna 26, men hylsan 4 har nu frigjorts och vägmärket 1 faller omkull. Vägmärket 1 kan därefter resas och med handkraft åter- föras till sitt ursprungsläge, varvid mekanismen inuti hylsan 4 utför en rörelse som är analog med men motsatt den nyss beskrivna.Normally, the elevations 28 hold the road sign 1 in a vertical position, in that the springs / rubber cushions 26 provide a sufficient clamping force to prevent the roller 15 from rolling past the elevations 28 in either direction. However, if the road sign 1 is hit or subjected to another abnormal stress, the spring forces of the springs 26 can be overcome. The springs 26 are thereby compressed, the roller 15 rolling past one of the elevations 28, the lower shaft pin 16 being lifted up in the grooves 17 and the support arms 18 being lifted upwards, the upper shaft pin 9; which is fixed relative to the sleeve 4, performing a relative movement in the grooves 20 during compression of the springs / rubber pads 26. At the same time the whole sleeve 4 is rotated in the joint 5, i.e. around the upper shaft pin 9. As soon as the roller 15 has passed either of the elevations 28, the roller 15 returns by means of the springs 26, but the sleeve 4 has now released and the road sign 1 falls over. The road sign 1 can then be raised and returned by hand to its original position, the mechanism inside the sleeve 4 performing a movement which is analogous to but opposite to the one just described.
