Definitions

• the invention relates to the in the introduction of the patent claim 1 more exactly defined door for the load space of the lorry, particularly to the door fitted on the wall of the load space of the lorry.
• the door construction of the load space of the lorry which consists of two horizontally hinged, in different direction opening door halves which have been joined together with a wire cable.
• the wire cable joined to the lower door half which wire cable has been joined by the other end to the upper edge of the higher door half causes the opening movement of the higher doof half in which case the higher door half rotates around the jointed points in the horizontal position in the inner part of the load space.
• the movement of the higher door half is controled with guide rollers and guide bars.
• the purpose of this invention is to represent the door of the load space of the lorry with which the opening of the whole wall of the load space is gained advantageously. Then in that case of the closed load space the advantages of the closed load space are on the other hand gained concerning the protection of the article and the load . space can at that very moment be unloaded and loaded advantageously.
• FIG. 1 shows in a perspective view the lorry on the wall of the closed load space of which has been fitted the door according to the invention
• Fig. 2 shows the same with the door in the opened position a d
• Fig. 3 and 4 shows the opening and shutting apparatus according to the invention from one side, in»other words, viewed from the end of the load space in which case figure 3 shows the door shut and the apparatus in the corresponding position and figure
• the door opening of the load space is a little smaller than the wall of the load space is,. Any ⁇ way, the..door opening.can be made as broad as the vail of the load space is, too.
• the opening and shutting apparatus according to the figures 3 and 4 has been fitted in the both end surfaces of the load space, on that edge, in which the door 2, 3 according to the invention is inserted.
• the apparatus according to the figures 3 and 4 consists of the vertical beam 8 fastened on the edge of the end surface 4 or 5 with a certain distance from that apparatus. In that case there is a certain chap between the beam 8 and the end surface 4 # 5 in which chap the lever 9 can rotate while the apparatus is working.
• the lever 9 has been jointed with the link
• the wire cable has been fastened in the door half 3 nearly in its higher edge on the edging 7- That end of the lever in which the wire cable 12 has been fastened has been furnished with the arch like expansion component 14 in which case the too big tensions of the wire cable are avoided which tensions are caused by the too little bending radius.
• the door according to the invention is used in the following way.
• the lockings are opened (not shown in the figures).
• the lower doof half 3 starts almost automatically rotating around the hinging point 15 in the arrow 16 direction.
• the wire cable 12 is tightened and in the shutting position of the door the
• IP lever 9 in almost vertical position starts rotating around its jointed point 10 (anticlockwise in the figure).
• the in the other end of the lever 9 fastened roller 11 starts rotating against the edge 6 of the higher door half by forcing it to rotate around its hinging point 17 according to the arrow 18.
• the opening movement stops when the lever has rotated about 180 , in other words, the lower door half 3 in in nearly vertical position and the wire cable 12 has been tightened almost straight and correspondingly the higher door half 2 is in nearly vertical position.
• the final position of the opening movement is described in the figures 2 and 4.
• the shutting takes place in the contrary order in which case the door 3 is lif ted in the arrow 19 direction in the figure 4.
• the lifting of the lower part 3 is eased throuhg the wire cable and the lever with the downwards directed movement of the higher part 2.
• the door according to the invention can easily be applied to be enginedriven in which case the engine is fitted to drive the gears inserted instead of the rollers 13 and the wire cable 12 is replaced with the chain 'running through the gears.
