Abstract

A brake system in wheeled walking frames or the like comprises a braking device and a handle (10) with a brake lever (20). The braking device acts against a wheel, and the brake lever has a braking position and a locking position. In use, the brake lever actuates the braking device via one end (50) of a connection (40). The other end (43) of the connection (40) abuts against a pressure surface (25, 26) adjacent the brake lever. The brake lever is rotary about two separate rotation centres (23, 24). The one rotation centre (24) functions in the braking position and the other (23) in the locking position.

Description

20 25 30 514 269 2 fig 2 vid normal bromsníng, och slutligen fig 3 i låsläge. 20 25 30 514 269 2 2 g 2 during normal braking, and finally fi g 3 in locking position.

De i bromsen ingående huvuddetaljerna är ett handtag l0, en bromsspak 20, ett lagerhus 30, en förbindelsedel 40 och ett bromsdon 50. Vidare ñnns ett band 60 som förenar handtaget 10 och bromsspaken 20.The main details included in the brake are a handle 10, a brake lever 20, a bearing housing 30, a connecting part 40 and a brake device 50. Furthermore, there is a belt 60 which joins the handle 10 and the brake lever 20.

Bromsspaken 20 utgöres i princip av två partier, en greppdel 21 och en funk- tionsdel 22, vilken i sin tur omfattar två vridningscenüa, ett yttre 23 och ett inre 24. Funktionsdelen har två kontaktpartier 25 och 26, vilka under tryck ~ från en spiralfi äder 44 glider mot ytor 41 och 42 anordnade på förbindelse- delens 40 övre ände 43. Vid temporär bromsning trycks bromsspakens 20 greppdel 21 i riktning mot handtaget 10 under hoppressning av spiralijädern 44. Bromsspaken kommer därvid att vridas kring ett vridningscentrum 24 och kontaktytan 25 kommer att glida mot ytan 41 på förbindelsedelens 40 ände 43, som fig 2 visar. Under hoptryckriingen av fjädern 44 kommer förbindelse- delen 40 att pressas nedåt och bromsdonet 50 att träda i funktion (ej visat på figurerna). Efter bromsningen återgår bromspaken automatiskt till neutralläge enligt fig l.The brake lever 20 consists in principle of two parts, a grip part 21 and a function part 22, which in turn comprises two rotational scenes, an outer 23 and an inner 24. The functional part has two contact parts 25 and 26, which under pressure ~ from a spiral fi spring 44 slides against surfaces 41 and 42 arranged on the upper end 43 of the connecting part 40. During temporary braking, the grip part 21 of the brake lever 20 is pressed towards the handle 10 while compressing the spiral spring 44. The brake lever will then be rotated about a center of rotation 24 and the contact surface 25 to slide against the surface 41 on the end 43 of the connecting part 40, which fi g 2 shows. During the compression of the spring 44, the connecting part 40 will be pressed downwards and the brake device 50 will come into operation (not shown in the figures). After braking, the brake lever automatically returns to the neutral position according to fi g l.

För att bringa bromsen i fast låsläge, som fig 3 visar, trycks bromsspaken 20 nedåt, även nu under hoppressning av fiädem 44, men med den skillnaden att vridningscentret 23 nu är ett annat. Vid vridningen kommer glidytan 26 som är försedd med ett urtag 27 i kontakt med en tapp 42 på förbindelsedelens övre ände 43. När urtaget 27 passerar tappen 42, faller den in i detta 27 och låser med en viss kraft bromsspaken i detta läge. Den kraft som sedan behövs för att lossa bromsen är visserligen inte speciellt stor men kan för en svag hand innebära vissa problem om brukaren samtidigt måste stödja sig mot handtaget. För att underlätta lossandet är därför bromsanordningen försedd med ett band 60, företrädesvis av textil, vars ändar är förbundna med hand- taget respektive bromsspaken. Ett lätt tryck av ett finger mot bandet i det läge som visas i fig 3 (med handen fortfarande kvar på handtaget) ger tillräcklig kraft att lossa bromsen.To bring the brake into a fixed locking position, as shown in Fig. 3, the brake lever 20 is pushed down, even now while compressing the edema 44, but with the difference that the center of rotation 23 is now different. Upon rotation, the sliding surface 26 provided with a recess 27 comes into contact with a pin 42 on the upper end 43 of the connecting part. When the recess 27 passes the pin 42, it falls into it 27 and locks with a certain force the brake lever in this position. The force that is then needed to release the brake is admittedly not particularly great, but for a weak hand can cause certain problems if the user also has to lean against the handle. To facilitate unloading, the braking device is therefore provided with a strap 60, preferably of textile, the ends of which are connected to the handle and the brake lever, respectively. A light pressure of a motinger against the belt in the position shown in fi g 3 (with the hand still on the handle) provides sufficient force to release the brake.
