Definitions

• the subject invention concerns a connecting device designed to fit together profiled members in junction areas in vehicle chassis, vehicle bodywork and similar components by means of angle irons and fasteners.
• the fasteners are in the form of bolt joints, comprising bolts and nuts or preferably romboid nut disc
• the profile members are formed with underc grooves in which the nut discs are received when the joint-forming components are tightened.
• the primary object of the subject invention is to eliminate the above disadvantages and to this end it suggests a device allowing maximum use of standard- configuration profile members and by means of which the assembly may be carried out in a rapid and uncomplicated manner without requiring unduly specialized training whil at the same time future expected increased demands on safety are met, for example with respect to the mounting of safety belts in buses and to roll-over safety means.
• This object and others related thereto are achieved by forming the profile members, at least in the junction areas, with facing grooves delimited by wall portions in which grooves fastening portions of complementary con- figuration formed on the angle irons may be received, and also by arranging the fasteners so as to extend trans ⁇ versely through the wall portions and the fastening por- tions to create a tightening frictional joint between the profile members and the angle irons.
• Fig. 1 is a perspective view as seen obliquely from the side of a junction in which the profile members are interconnected by means of angle irons and fasteners
• Fig. 2 is an angle iron in accordance with Fig. 1 in a lateral view.
• Fig. 1 The embodiment of the device in accordance with the invention as illustrated in Fig. 1 thus is intended for interconnection of profile members, generally designated by numeral 1, in one of several junctions 2 in a vehicle chassis or bodywork, in the preferred embodiment in a bus, a railway carriage or the like, with the aid of angle irons 3 and fasteners 4.
• the profile members 1 present facing grooves 6 which are delimited by wall portions 5 and which extend in the lengthwise direc ⁇ tion of the profile members 1 and essentially at right angles to that direction.
• the grooves 5 have an outwardly open U-shaped configuration in cross section with the wall portions 5 being formed by the legs of the U-shape, as illustrated in Fig. 1.
• the U-shaped grooves 6 serve to receive fastening portions 7 of complementary shape formed on the angle irons 3, the latter therefore preferably being L-shaped, as seen in side elevation.
• the fastening portions 7 thus form part of the legs of the L-shaped iron and they are received in the U-shaped grooves 6 in tight-fit engage ⁇ ment with the inner faces 8 of the wall portions 5.
• the fasteners 4 extend transversely through the wall portions 5 of the profile members 1 and the fastening portions 7 of the angle irons 3, i.e. at right angles to the profile members and the angle irons. In their mounted position, the fasteners 4 thus create a tightening frictional joint between the profile members 1 and the angle irons 3 with the load on the fasteners being exerted at right angles to the lengthwise extension thereof, and the risk of fatigue failure in the profile members and/or the ang irons thus are minimized.
• the fasteners preferably are in the form of bolt joints 4, but also rivet joints, screw joints or similar interconnection means are possible.
• the bolt heads 9 of the joints 4 and the nuts thereof, not shown are tightly in engagement with the external faces 10 of the wall portions 5, if needed supplemented with washers or similar inserts, not shown.
• the shanks, not shown, of the bolt joints 4 extend throug transverse holes 11 formed in the wall and fastening portions 5, 7 of respectively the profile members 1 and the angle irons 3.
• each profile member 1 preferably comprises two parallel grooves 6 including an intermediate wall portion 5, formed on respectively the top and bottom side of the member.
• each groove 6 thus receives the fastening portion 7 of the associated angle iron 3, the number of which equals that of the grooves, said angle irons 3 being positioned opposite each other, i.e. in congruent relationship.
• the profile members 1 as well as the angle irons 3 preferably are made from light metal, such as aluminium or an aluminium alloy. Other light metals and alloys thereof may, of course, be used.
• the profil members 1 preferably are extruded with the grooves 6 extending along the entire length of the profile members.
