The object of the invention is an arrangement in hatch structure (1) to be installed in a vehicle body (2). The arrangement comprises a hatch, the edges of which are bent downwards, which hatch is mainly horizontal when in the closed position, an opening (6) in the vehicle body (2), which opening (6) is smaller than the said hatch, a packing (4) for sealing the hatch and the opening (6) in relation to each other when the hatch is closed, and a hatch operating mechanism that incorporates at least one body part (7), which has sliding faces (8, 18) for a slide (9) on which the slide (9) rests, a lever (11) that is connected to the slide (9) by means of a first joint (12) and is supported near the edge of the opening (6) in the vehicle body (2) by means of a second joint (13), and a compression spring (10) located in the slide bed, which compression spring constantly exerts force on the slide (9) so as to push it. The said body part (7) is supported on the lower surface of the hatch and the compression spring (10) presses the slide (9) towards the edge of the hatch that is at the location of the said body part (7).

1. An arrangement in a hatch structure for installation in a vehicle body comprising:a hatch having downwardly bent edges and being disposed substantially horizontally when in a closed position, an opening in the vehicle body which is smaller in size than said hatch, a packing for sealing the hatch and the opening in relation to one another when the hatch is in the closed position thereof, and a hatch operating mechanism to allow for movements of the hatch between said closed position wherein the hatch and the opening are sealed in relation to one another and an open position wherein the hatch is in spaced relation to the hatch, wherein said hatch operating mechanism comprises: at least one body part fixed to a lower surface of the hatch so as to be within said opening when said hatch is in said closed position thereof, said at least one body part including slide faces which are oriented in a direction relative to a longitudinal axis of the vehicle, a slide operatively connected to the slide laces of said at least one body part so as to be slideable between an advanced position close to a respective hatch edge adjacent said at least one body part, and a retracted position which is spaced inwardly from said respective edge, a lever having one end that is connected to the slide by means of a first joint and an opposite end that is connected near the edge of the opening in the vehicle body by means of a second joint, and a compression spring operatively associated with the at least one body part so as to constantly exert a force on the slide in a direction so as to push said slide into said advanced position thereof. 2. An arrangement according to claim 1, wherein said lever is connected to said at least one body part by means of said first joint so as to be positioned eccentrically relative to the sliding faces of the the at least one body part, and wherein the lever has a length such that dead centre of the hatch operating mechanism is about half-way between the closed and open positions of the hatch.3. An arrangement according to claim 2, wherein the first joint includes a stop arrangement which contacts said lever to thereby limit the movement of the slide to prevent disconnection of the slide from the sliding faces of the at least one body part.4. An arrangement according to claim 3, wherein the opening in the vehicle body includes a front and rear edges transverse to driving direction of the vehicle, wherein each of said front and rear edges have at least two support points for the hatch operating mechanism.5. An arrangement according to claim 4, wherein said support points are spaced apart from one another along a respective one of said front and rear edges by a dimension between 25 cm-90 cm.6. An arrangement according to claim 1, comprising a respective hatch operating handle located under a lower surface of the hatch adjacent front and rear edges of the hatch in relation to the vehicle's driving direction to thereby allow the hatch at said front and rear edges thereof to be moved between said opened and closed positions by means of an operator manually lifting up or pulling down on a respective one of the hatch operating handles.7. An arrangement according to claim 6, wherein said hatch operating handles at said front and rear edges of said hatch are independently operable so that that by means of an operator manually lifting or pulling down a respective one of said hatch operating handles, it is possible to selectively open and close one of the front and rear edges of the hatch.8. An arrangement according to claim 7, wherein the operating handles are rod elements which are positioned substantially horizontally close to a respective hatch operating mechanism at the front and rear edges of the hatch.9. An arrangement according to claim 1, wherein the hatch operating mechanism further comprises hatch operating rods located both front and rear edges of the hatch relative to the vehicle's driving direction.10. An arrangement according to claim 9, wherein the hatch operating rods are positioned no closer than 5 cm to an edge of the opening in the vehicle body.11. An arrangement according to claim 1, wherein at least a major part of the hatch operating mechanism is formed of a plastics material.12. A hatch arrangement for a vehicle body, comprising:a support bracket defining an opening; a hatch lid sized to cover the opening of the support bracket; and a hatch operating assembly for allowing the hatch lid to be moved between a closed position wherein the hatch lid closes the opening, an intermediate position wherein the hatch lid is partially spaced with respect to the opening, and an opened position wherein the hatch lid is fully spaced with respect to the opening, wherein said hatch operating assembly comprises; (i) at least one body part fixed to a lower surface of the hatch lid and defining a slide surface; (ii) a slide member coupled to the slide surface of the at least one body part for sliding movements between an advanced position wherein the slide member is adjacent the support bracket, and a retracted position wherein the slide member is retracted inwardly away from said support bracket; (iii) a lever having opposed ends coupled pivotally to the slide member and the support bracket; and (iv) a spring member which exerts a spring force acting against the slide member so as to urge the slide member into said advanced position thereof, wherein initial movement of said hatch lid to said intermediate position from one of said closed or opened positions responsively causes said slide member to move from said advanced position and into said retracted position against the spring force of said spring member such that continued further movement of said hatch lid from said intermediate position and into another one of said closed or opened positions thereby responsively causes said slide member to move from said retracted position and into said advanced position under influence of the spring force of said spring member. 13. The hatch arrangement of claim 12, wherein said hatch lid has downwardly bent edges.14. The hatch arrangement of claim 12, wherein the support bracket includes a packing seal to seal the opening when the hatch lid is in said closed position thereof.15. The hatch arrangement of claim 12, wherein a respective said hatch operating assembly is provided at forward and rearward edges of said support bracket relative to a vehicle's driving direction, each said hatch operating assembly being independent operable so that one or both of respective front and rear edges of the hatch lid is capable of being moved between said closed and opened positions thereof.16. The hatch arrangement of claim 12, comprising an operator handle which allows an operator to manually push and pull the hatch lid to responsively move the hatch lid into its opened and closed positions, respectively.
