Description

Slepedoning for slepning av tømmer og liknende. Towing equipment for towing timber and the like.

Det er tidligere kjent slepedoninger There are previously known towing devices

for slepekjøring av tømmer og liknende. Disse slepedoninger er imidlertid mindre hensiktsmessige for kjøring i skogsterreng, da meiene ikke tilstrekkelig smidig kan følge markens ujevnheter. for towing timber and the like. However, these towing devices are less suitable for driving in forest terrain, as the mowers cannot follow the unevenness of the ground with sufficient flexibility.

I henhold til foreliggende oppfinnelse unngås denne ulempe ved at meiene i såvel vertikalretning som i horisontalretning er festet svingbare på en lastebjelke. Oppfinnelsen vises på tegningen, hvor fig. 1 er et sideriss av en slepedoning. According to the present invention, this disadvantage is avoided by the fact that the scythes in both the vertical and horizontal directions are fixed pivotably on a loading beam. The invention is shown in the drawing, where fig. 1 is a side view of a towing arrangement.

Fig. 2 et tilsvarende planriss. Fig. 2 a corresponding plan.

Fig. 3 er et sideriss av en slepedoning forsynt med hjul, og fig. 4 et tilsvarende planriss. Fig. 3 is a side view of a towing device equipped with wheels, and fig. 4 a corresponding floor plan.

Fig. 5 er et perspektivriss. Fig. 5 is a perspective view.

På tegningen betegner 1 og 2 to meier, In the drawing, 1 and 2 denote two teats,

som fortil på innsiden er forsynt med hver sitt øye-beslag 3, i hvilke øyer der er svingbart festet endene av en med trekkøye 4 forsynt tverrstang 5. På hver av meiene 1, 2 er der dreibart lagret en vertikal svinge-tapp 6, som er festet til en horisontal lastebjelke 7, 8 som består av to koaksiale i forhold til hverandre dreibare rørstykker 7, 8 av hvilke det ene 7 er forsynt med en sylindrisk tapp eller rør 9, som er stukket inn i det annet 8. Røret 8 er forsynt med en sperretapp 10 som går inn i et lang-strakt hull 11 i rørstykket 9. which on the inside are each provided with an eye fitting 3, in which eyes the ends of a crossbar 5 equipped with a draw eye 4 are pivotably attached. is attached to a horizontal load beam 7, 8 which consists of two coaxial relative to each other rotatable pipe pieces 7, 8 of which one 7 is provided with a cylindrical pin or pipe 9, which is inserted into the other 8. The pipe 8 is provided with a locking pin 10 which goes into an elongated hole 11 in the pipe piece 9.

På hvert av svingetappenes 6 øvre beslag er der festet to radielle framspring 12, som er anordnet til i likhet med en bajo-nettlås, med et i et beslag 15 på meien 1 resp. 2 anordnet hull, å samvirke med kon-sentrisk med svingetappen anordnede ring-sektorer 13 med overskytende kantpartier 14. Framspringene 12 og ringsektorene er anordnet slik og omfatter sådanne vinkler, at svingetappen bare kan innføres i hullet 16 når rørstykket 7 resp. 8 er parallelt med meien 1 resp. 2 og etter at dreietappen 6 er dreiet 90° vil fremspringene 12 ligge under de overskytende kantpartier og hindre at dreietappen kan trekkes ut. On each of the pivot pin's 6 upper fittings, two radial protrusions 12 are attached, which are arranged in the same way as a bajo net lock, with a fitting 15 on the coulter 1 resp. 2 arranged hole, to cooperate with ring sectors 13 arranged concentrically with the pivot pin with excess edge portions 14. The protrusions 12 and the ring sectors are arranged in such a way and comprise such angles that the pivot pin can only be introduced into the hole 16 when the pipe piece 7 resp. 8 is parallel to the mein 1 resp. 2 and after the pivot pin 6 has been turned 90°, the protrusions 12 will lie below the excess edge parts and prevent the pivot pin from being pulled out.

Ved den i fig. 3 og 4 viste utførelses-form er hver av meiene baktil forsynt med et hjul 17 for kjøring på bar mark. By the one in fig. In the embodiment shown in 3 and 4, each of the mowers is provided at the rear with a wheel 17 for driving on bare ground.

Såvel meiene ifølge fig. 1 og 2 som de med hjul forsynte meier ifølge fig. 3 og 4 er dimensjonert slik at de er utskiftbart anvendelige med en og samme lastebjelke samt en og samme tverrstang, og man har således en kombinert kjelke og kjerre. Both the mow according to fig. 1 and 2 as the wheel-equipped milkers according to fig. 3 and 4 are dimensioned so that they can be interchangeably used with one and the same load beam and one and the same cross bar, and you thus have a combined sledge and cart.

Ved anordningen ifølge oppfinnelsen kan meiene dels svinge sammen i horison-talretningen parallelt med hverandre og With the device according to the invention, the mowers can partly swing together in the horizontal direction parallel to each other and

dels svinge hver for seg i vertikalretningen, partly swing separately in the vertical direction,

slik at de smidig kan tilpasse seg etter markens uregelmessigheter. so that they can flexibly adapt to the irregularities of the ground.

Claims

1. Towing equipment for towing timber etc. 1. where the cutters, which can be equipped with wheels at the back for driving on bare ground and which are pivotably connected at the front with a common crosspiece (5), are pivotable vertically in relation to each other and connected with a load beam in such a way that they can swing in a horizontal direction in relation to the load beam, characterized in that the load beam is formed by two coaxial parts (7, 8) which are rotatable in relation to each other and connected to each of the beams.

2. Towing as stated in claim 1, characterized in that two pivots (6) are rigidly attached to each of the two parts (7, 8) of the load beam and are stored in a hole (16) in a fitting (15) on each of the sides.

3. Towing device as specified in claim 2, characterized in that each of the truck's two parts is provided with a mainly circular, with the respective pivots (6) coaxial disc (12) which is aligned to, in contact with the fitting (15), with two radial projections (12') to insert under two flanges (14) which are placed on the fitting and is parallel to this, which flanges are positioned in such a way that they prevent the pivot pin (6) from being pulled out of the hole when the truck is not approximately parallel to the screed.
