DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device for the detachable securing of a repair platform constructed of beams and substantially rectangular, on which a damaged vehicle is intended to be secured during the work of repairs, whereby said beams, on their respective outwardly facing sides are constructed with channel-shaped profiled members placed in an area of the upper and lower horizontal edges of said sides, having mutually facing openings, said profiled members being conventionally used for the fixing of equipment for repair work.
Such a securing device is known from EP-B1-0065942. The securing member in this case contains a seat of channel-shaped cross-section and consists of three plates: an upper one, a lower one and a plate joining these with a space between them, intended to engage with the upper, lower and outer sides of the beam. A locking member consisting of a rotatably mounted knob can, by being rotated half a turn, be made to grip round the inner lower corner, and to engage with a lower part of the inner side of the beam. The knob is designed with a locking key intended to prevent it turning during the work of repairs, which would lead to the supporting arrangement coming loose from the beam.
It has been found that this known supporting arrangement, in the event of a lack of balance, can slide to some extent along the beam, which, naturally, is detrimental to a good repair outcome and even constitutes a danger to the personnel carrying out the work of repair.
Furthermore, this known device is relatively cumbersome and time-consuming in its securing to the repair platform, and it also suffers from the drawback that one could easily forget to place the key in the intended manner.
The object of the present invention is to provide a device of the type first defined hereinabove by means of which an effective fixing is achieved on the repair platform, and the construction of which is such that slipping movements between the supporting arrangement and the repair platform are eliminated.
This is achieved according to the invention in that, at the respective beam, the lower profiled member projects below the outwardly facing lower edge line of the beam side; in that the supporting arrangement is constructed with a member, on the one hand, for engagement with at least the upper side of the channel-shaped profiled member and with the front sides of the channel-shaped members, and, on the other hand, for engagement into the upper channel-shaped member and behind the downwardly-projecting part of the lower channel-shaped profiled member below the forward lower edge line.
An advantageous construction of the securing arrangement is characterized, as claim 2 indicates, in that said member contains a structural part stationary relative to the supporting arrangement which is designed to engage with the upper side of the upper channel-shaped member and with the front sides of the channel-shaped members, a first lever part rotatable around a first axle designed to bring about an engagement behind the lower channel-shaped member, and a second locking part, rotatable around a second axle and situated on an upwardly pointing projection on the first part, designed to come into engagement with the downwardly facing opening of the upper channel-shaped member.
The invention will be explained in detail hereinbelow with reference to the attached drawings in which FIGS. 1a and 1b show, in plan view from the side, a securing arrangement of the invention in and out of engagement with a repair platform. FIG. 2 shows the securing arrangement in a plan view seen from the repair platform in FIG. 1a.
In the drawing 1 denotes generally part of a supporting platform carried by wheels 2 which, in everything except the securing arrangement, is of conventional type, and 3 denotes generally a part of a rectangular repair platform constructed of beams. This is, on its outwardly facing sides 3a, provided with two channel-shaped profiled members 4a, 4b, which, with their openings facing each other, are placed above and below on said outwa
