Patent 11142044 - Protective windscreen arrangement > Claims

  • 1. A shock absorbing vehicle window arrangement for a vehicle cab, the shock absorbing vehicle window arrangement comprises: a transparent windscreen having a thickness in the range 9 mm-14 mm and having a height, anda metal frame, comprising:an inner portion at least partially extending on an inside of the transparent windscreen, andan outer portion, at least partially extending on an outside of the transparent windscreen, whereinthe outer portion overlaps the transparent windscreen with at least 1% of the height of the transparent polymer windscreen,wherein the shock absorbing vehicle window arrangement further comprises:an additional transparent polymer windscreen having a thickness in the range 3 mm-8 mm placed on the outside of the transparent windscreen, wherein the additional transparent polymer windscreen is lighter than the transparent windscreen and comprises a plurality of holes or recesses for receiving fixation elements for fixating the additional transparent polymer windscreen to the metal frame, anda spacer configured to be placed in-between the transparent windscreen and the additional transparent polymer windscreen interconnecting edge portions thereof, such that an enclosed space is formed between the transparent windscreen, the additional transparent polymer windscreen and the spacer.
    • 2. The shock absorbing vehicle window arrangement according to claim 1, further comprising an additional metal frame placed on the outside of the additional transparent polymer windscreen.
    • 3. The shock absorbing vehicle window arrangement according to claim 1, wherein the spacer comprises a desiccant for removing moisture present in the enclosed space.
    • 4. The shock absorbing vehicle window arrangement according to claim 1, wherein the inner portion is configured to receive screws for fixating the transparent windscreen.
    • 5. The shock absorbing vehicle window arrangement according to claim 1, wherein the transparent windscreen is curved, and wherein the inner portion of the metal frame is curved along a surface facing the transparent windscreen.
    • 6. The shock absorbing vehicle window arrangement according to claim 1, wherein at least one of the plurality of holes or recesses is arranged to overlap a through hole of the transparent windscreen thus allowing the additional transparent polymer windscreen to be fixed to the inner portion of the metal frame.
    • 7. The shock absorbing vehicle window arrangement according to claim 1, wherein the transparent windscreen comprises a polymer material.
  • 8. A shock absorbing vehicle window arrangement for a vehicle cab, the shock absorbing vehicle window arrangement comprises: a transparent windscreen having a height, anda metal frame, comprising:an inner portion at least partially extending on an inside of the transparent windscreen, wherein the inner portion comprises a fixation interface configured to fixate the shock absorbing vehicle window arrangement to the vehicle cab, andan outer portion, at least partially extending on an outside of the transparent windscreen, whereinthe outer portion overlaps the transparent windscreen with at least 1% of the height of the transparent windscreen,wherein the shock absorbing vehicle window arrangement further comprises:an additional transparent windscreen placed on the outside of the transparent windscreen, wherein the additional transparent polymer windscreen is lighter than the transparent windscreen and comprises a plurality of holes or recesses for receiving fixation elements for fixating the additional transparent polymer windscreen to the metal frame, anda spacer configured to be placed in-between the transparent windscreen and the additional transparent polymer windscreen interconnecting edge portions thereof, such that an enclosed space is formed between the transparent windscreen, the additional transparent polymer windscreen and the spacer.
    • 9. The shock absorbing vehicle window arrangement according to claim 8, wherein the fixation interface comprises a plurality of through-holes.
    • 10. The shock absorbing vehicle window arrangement according to claim 8, further comprising an additional metal frame placed on the outside of the additional transparent polymer windscreen.
    • 11. The shock absorbing vehicle window arrangement according to claim 8, wherein the spacer comprises a desiccant for removing moisture present in the enclosed space.
    • 12. The shock absorbing vehicle window arrangement according to claim 8, wherein the transparent windscreen is curved, and wherein the inner portion of the metal frame is curved along a surface facing the transparent windscreen.
    • 13. The shock absorbing vehicle window arrangement according to claim 8, wherein the transparent windscreen has a thickness in the range 9 mm-14 mm and the additional transparent polymer windscreen has a thickness in the range 3 mm-8 mm.
    • 14. The shock absorbing vehicle window arrangement according to claim 8, wherein the transparent windscreen comprises a polymer material.
  • 15. A shock absorbing vehicle window arrangement for a vehicle cab, the shock absorbing vehicle window arrangement comprises: a transparent windscreen having a height, anda metal frame, comprising: an inner portion at least partially extending on an inside of the transparent windscreen, andan outer portion, at least partially extending on an outside of the transparent windscreen, wherein the outer portion overlaps the transparent windscreen with at least 1% of the height of the transparent windscreen,wherein the shock absorbing vehicle window arrangement further comprises:an additional transparent windscreen placed on the outside of the transparent windscreen, wherein the additional transparent polymer windscreen is lighter than the transparent windscreen and comprises a plurality of through holes for receiving fixating screws for fixating the additional transparent polymer windscreen to the metal frame, wherein at least one of the plurality of through-holes have a cross-sectional area being at least 1.5 times larger than the cross-sectional area of the fixating screws, enabling movement between the additional transparent polymer windscreen and the metal frame, anda spacer configured to be placed in-between the transparent windscreen and the additional transparent polymer windscreen interconnecting edge portions thereof, such that an enclosed space is formed between the transparent windscreen, the additional transparent polymer windscreen and the spacer.
    • 16. The shock absorbing vehicle window arrangement according to claim 15, further comprising an additional metal frame placed on the outside of the additional transparent polymer windscreen.
    • 17. The shock absorbing vehicle window arrangement according to claim 15, wherein the spacer comprises a desiccant for removing moisture present in the enclosed space.
    • 18. The shock absorbing vehicle window arrangement according to claim 15, wherein the transparent windscreen is curved, and wherein the inner portion of the metal frame is curved along a surface facing the transparent windscreen.
