Definitions

  • the present invention relates to a railing for mounting along a walkway of a vehicle, preferably along a platform mounted on a land-based vehicle.
  • the railing includes an elongated hand rail section, one or more base sections, and a plurality of elongated posts, with the posts each being pivotally connected to the hand rail section and to a base section.
  • the railing is collapsible from a raised configuration wherein said posts are in an upright position, to a collapsed configuration wherein the posts assume a lying down position.
  • Collapsible railings for vehicles are known in the art.
  • the known collapsible railings through their design give rise to wind generated noise as the vehicle moves.
  • dirt and debris tend to collect in the bearings of the known railings, thus preventing their proper functioning.
  • the present invention aims at solving the above problems by the railing including a compartment being defined in part by the elongated hand rail section and being adapted to receive the posts when the railing is in the aforementioned collapsed configuration.
  • the invention also relates to a vehicle carrying a railing as claimed in claims 1-15.
  • FIG. 1 and 2 show a tanker with a railing according to the invention, in the collapsed and raised configurations, respectively,
  • Fig. 3 and 4 are side views showing a detail of a railing according to the in- vention in the collapsed and raised configurations, respectively,
  • Fig. 5-9 are perspective views showing details of a railing according to the invention.
  • Fig. 10 and 11 are cross-sectional views showing embodiments of the railing according to the invention, in the raised and lowered configuration.
  • Fig. 1 shows a tanker 1 which on its top has a platform 10 defining a walkway on which personnel can walk.
  • a ladder 5 allows a person to climb onto the platform.
  • Reference numeral 20 designates a railing according to the invention, shown in the collapsed configuration and mounted next to the platform 10.
  • Fig. 2 shows the railing of fig. 1 in a raised configuration wherein an elon- gated hand rail section 30 of the railing 20 is at the typical level of the waistline of a person standing on the walkway.
  • a plurality of posts 60 are pivotally connected to the hand rail section 30 at a first upper end and to the tanker 1 at the second, lower end.
  • the posts 60 preferably have a D-shaped cross- section.
  • the railing 20 includes an elongated base section 40 which is secured to the tanker 1 next to the platform 10 and to which the second end of the posts 60 is pivotally connected.
  • the hand rail section 30 is formed in cross-section as a ⁇
  • the base section 40 is formed in cross-section as an inverted IT In the collapsed configuration shown in fig. 1 wherein the longitudinal edges of the side flanges 36 of the hand rail section 30 abut against the edges of the side flanges 46 of the base section 40, the posts 60 will lie completely enveloped by the elongated hand rail section 30 and the elongated base section 40.
  • the posts 60 Through the posts 60 thus being received in the compartment shown by reference numeral 21 in fig.
  • the railing 20 according to the invention to a large extent prevents collection of dirt or debris where the posts are journalled which potentially could hinder operation of the railing 20.
  • Fig. 3 shows a detailed side view of the preferred embodiment of the railing 20 in the collapsed configuration.
  • the railing 20 has an elongated and continuous hand rail section 30 which in cross-section resembles a I ⁇ l, defining a downwardly open channel 32, and a continuous base section which in cross- section resembles an inverted Fl defining an upwardly open channel 42, cf. fig. 2.
  • the posts 60 are received between the opposite flanges 36, 46 of the hand rail section 30 and the base section 40, respectively, and are pivotally connected to the hand rail section 30 and the base section 40 by through- going bolts 22, 24.
  • Fig. 3 also shows one of a plurality of spaced apart brackets 50 formed as an inverted Fl, suitable for mounting the elongated base section 40 onto the vehicle 1 and receiving the same bolts 24 that are used for securing the posts 60.
  • the elongated base section 40 shown in fig. 3 may in an alternative embodiment (not shown) be dispensed with whereby in the collapsed configuration, and other than in the areas of the brackets 50, the posts 60 will be received only by the downwardly open channel 32 of the hand rail section 30 which then forms a post receiving compartment 21.
  • the plurality of brackets 50 defines a plurality of individual base sections 50 arranged with a spacing of eg. about 1 m along the length of the railing 20.
  • the ends of the posts 60 are preferably each configured with a straight end portion 63 that extends essentially perpendicular to the length of the post 60, and a rounded portion 62 that follows the contour of about one quarter of a circle with centre at through-going post holes 23, 25 that receive the bolts 22, 24. in this manner the railing 20 can only be laid down in one direction as shown in fig. 3, and any attempt to lay down the railing by turning the posts 60 clockwise in fig. 4 will be resisted by the straight end portions 63 of the posts 60 abutting against the respective inside bottom faces 34, 44 of the hand rail section 30 and the base section 40.
  • Fig. 5 shows the railing 20 as the user manually pulls up the hand rail section 30 to manually raise the railing 20.
  • a wire 70 extends through holes 66 formed in the posts 60 and is preferably kept taut by a spring 72 secured to one end of the wire 70 and to one of the posts 60.
  • the wire 70 provides an additional safety against personnel falling off the walkway, and through the wire 70 being kept taut it will not interfere with the laying down of the posts 60.
  • a lock is provided to allow the railing 20 to be lowered to the collapsed configuration.
  • the lock may be provided by an actuator to be discussed below which serves to raise and lower the railing 20.

  • Fig. 10 shows an alternative embodiment of the profiles forming the hand rail section 30 and the base section 40 wherein the hand rail section profile has a larger width than the base section profile such that when the railing 20 is in the collapsed configuration the edges 31 , 41 of the hand rail section 30 and base section 40, respectively, will not abut against each other.
  • the hand rail section 30 web 34 overlies the opposed base section 40 flanges 46, and the hand rail 30 web 34 defines the post 60 receiving compartment 21 together with the flanges 46 and web 44 of the base section 40.
  • Fig. 10 also shows the cross-bolts 22, 24 connecting the posts 60 to the hand rail section 30 and base section 40, respectively. Upwardly open slits (not shown) formed in the flanges of base section 40 receive the cross-bolts 22.

Abstract

La présente invention concerne une rambarde (20) à fixer le long d’une passerelle (10) de véhicule (1), de préférence le long d’une plateforme montée sur un véhicule basé au sol. La rambarde comprend une section (30) de main courante allongée, une ou plusieurs sections de base (40, 50) et une pluralité de montants (60) allongés, les montants (60) étant respectivement reliés de façon pivotante à la section de main courante et à une section de base. La rambarde peut être rabattue depuis une configuration relevée dans laquelle lesdits montants sont en position verticale, pour prendre une configuration rabattue dans laquelle les montants prennent une position horizontale. La rambarde comprend un compartiment défini en partie par la section de main courante allongée et adapté pour recevoir les montants lorsque la rambarde est dans la configuration rabattue susmentionnée.
