Description

Device for mounting a crash or impact device on or to a delivery van absorbing energy from vehicles colliding with the delivery van The present invention relates to a device for mounting on or attached to a delivery van mounting a collision or impact device for absorbing energy against the delivery van collision vehicles. Such arrangements are generally known as Truck Mounted Attenuators (TMA), and in particular from the International patent application W02017138809 of the present applicant. This concerns an energy-dissipating device inscribed with cutting blades. TMAs are, as the name suggests, mounted on trucks and are usually attached to them. connected. However, it may also be desirable to equip delivery vans with such an attenuator, considering the number of accidents that occur with preparatory work along motorways parked delivery vans. However, those delivery vans are generally intended primarily for other purposes, such as transport. of work equipment, and not merely as a mobile carrier of a collision or impact device, which makes it desirable for such a collision or impact device to be temporarily attached to it and / or can be removed from it. Where the trucks equipped with a TMA are manufactured or converted specifically for this purpose. to be or become, this does not apply without further ado to delivery vans. Their construction allows for the attachment not simply apply heavy attributes, and also the requirements of maneuverability and / or the non- obstructing the regular use of the delivery van, such as the rear doors thereof when If a TMA is mounted, it constitutes relatively complex boundary conditions. It is therefore an objective of the present invention to be a device for attaching to or on a installing a crash or impact device on a delivery van for absorbing energy from against to provide the delivery van with collision-proof vehicles that eliminates the aforementioned disadvantages, and / or removes obstacles. To that end, the invention provides a device for mounting on or to a delivery van of a collision or impact device for absorbing energy from impacting the delivery van vehicles, comprising: First engagement devices for pre-assembly on a roof, in particular on a or multiple roof rack mounting rails provided for this purpose, of the delivery van; 1 Second engagement means for pre-assembly on a chassis, in particular on a carrier connected thereto, even more specifically to a towbar support beam, of the delivery van; One extending between the first and second means of engagement and suspension structure for the impact or striking device; A collision or impact device connected to the suspension structure, such as a collision or bumper, designed to be moved relative to the suspension structure between: 0 a folded resting position in which the impact or collision device is against a rear or is placed on the top of the delivery van; and o An unfolded operating position, in which the impact or collision device is positioned from the rear of the delivery van extends backwards. The first and second means of application and those connected therewith and those between them extending suspension structure can form a joint frame or auxiliary chassis for the bearing the impact or shock device, and thereby the forces required for bearing in such a way distribute over the delivery van so that no further structural modifications to that delivery van be required. Such a van is generally equipped with roof rack mounting rails and often also of one located at a rear, perpendicular to that rear support extending to the chassis, in particular as a towbar support beam executed. The second means of engagement can engage on such a support. The thrust or impact device may include a cushion or similar shock-absorbing device, but at preferably an energy-dissipating device with cutting blades, where the impact of a collision is captured by using the impulse to cut metal or aluminium tubes with to blades provided with an impact surface as described in EP3414397. In order to be able to use the delivery van for regular work as well, or the TMA to can switch between different delivery vans, the first and second can gripping devices are preferably detachable gripping devices. For mounting on Roof rack mounting rails can have clamp screw or bolt attachments. The means of gripping and the supporting structure of the device according to the invention may at manufactured at least partially from aluminium or fibre-reinforced or non-fibre-reinforced plastics be, to load the delivery van with as little weight as possible. Since such roof rack mounting rails are usually located on either side of the roof of a delivery van, located at the transition between the roofs and the side wall of a delivery van, it is 2 favorable when the first means of application are mutually parallel to a rod or comprise beam-shaped elements, arranged to position themselves during use in a longitudinal direction of the delivery van to extend over the roof of the delivery van. The towbar support beam typically extends at the level of the rear bumper and / or underneath. rear doors of the delivery van outwards, in the form of a tubular beam. For attachment thereon, the second means of engagement may be a hook, clamp, or support-shaped elements, designed to engage with, or rest on, the chassis or the components connected to the chassis carrier, in particular the towbar support beam or a similar at the rear of the delivery van installed and more specifically in a width direction along the rear carrier extending from the delivery van. The impact or shock device can be rotatably connected to the suspension structure, whereby this is placed against the rear of the delivery van in the folded resting position, whereby hinged at an underside, at the level of the towbar support beam, the rear bumper and / or under the back doors. Alternatively, the impact or collision device can be translatable with the suspension structure. are connected, whereby the impact or collision device in the folded resting position on the roof of the delivery van is positioned. The crash or impact device can also operate during relocation between the folded resting position and the unfolded operating position in the horizontal orientation remain. To this end, it first moves by means of a horizontal translation across the roof to the rear of the delivery van, to then, by means of a vertical translation downwards, into is brought to the unfolded operating position. For the horizontal and vertical Translational movements can be provided with guides and a drive system. In a further embodiment, the suspension structure is designed to position itself in mounted condition along the rear sides of the delivery van from the first to the second to extend means of gripping, thereby an opening for opening one or more offering rear doors or a tailgate of the delivery van. The device according to the invention may furthermore be connected to the suspension structure. include signaling board. The signaling board can be between a horizontal resting state and a vertical operating condition be movable by means of rotation around a horizontal rotation axis extending in the width direction of the bus, for example at the rear of the roof.
