Definitions
- This invention refers to a device for interconnecting vertical and horizontal elements particularly tubular elements for scaffolds and the like.
- the main object of the invention thus has been to provide a device which is not affected with these drawbacks and which additionally can be. manufactured as a sturdy and easy to handle product at relatively low costs.
- Fig. 1 is a side elevation of a portion of a vertical and a horizontal element with the device according to the invention in a first aligning position.
- Fig. 2 shows the device according to fig. 1 but with the device in a hooking position.
- Fig. 3 shows the device according to fig. 1 in a hooked and locked position
- Fig. 4 finally is a perspective view of a part of the device.
- the numeral 1 generally designates one of the elements, for instance a vertically disposed upright which is to be connected to a substantially horizontally extending element, generally designated as 2.
- the elements 1 and 2 usually are tubes for scaffolds and the like.
- the vertical elements 1 have one or several yoke os socket shaped members 3 arranged in connection with the proposed joining points. These members, in the following referred to as yokes, are usually welded to the vertical elements and serve to cooperate with the new connecting device, generally designated as 4.
- This connecting device includes a hook element 5, which according to fig. 4 has an upper wall 6 from one end of which and at right angles thereto extends a downwardly directed hook portion 7 and from the opposite end of which extends a downwardlydirected wall 8, which forms an acute angle with the upper wall and in turn continues in a lower wall
- a slot 12 extends from the free end of the lower wall 9 and parallel to the opening 10.
- the hook element 5 is secured to one end of the horizontal element 1, preferably by welding.
- the second part of the connecting device consists of a specially shaped wedge which has an upper side surface 14a and a lower side surface 14b in line therewith. Intermediate said surfaces the wedge has in the left hand side thereof a recess 15, which is limited by a sloping surface 16 extending from the lower surface 14b, said sloping surface in turn continuing in an inner surface 17 parallel to the surfaces 14a, 14b, said inner surface being located at a distance from a plan throughithe surfaces 14a, 14b which substantially corresponds to the distance between the outer surface of the yoke 3.
- the right hand side 18 of the wedge constitutes the active sloping surface of the wedge and in the upper end thereof the wedge is shaped as a hammer-like part 19.
- the device here described works in the following manner:
- the wedge In the initial position the wedge is in an upper in-active position in which it by gravity takes the illustrated somewhat oblique position.
- the wedge has the point of balance so located that the wedge in the illustrated upper position will bear with the upper pin 20 thereof against the upper side of the wall 6 and with the lower pin against the under side of the wall 6. This is true because the pin 21 is located at that side of the wedge which does not face the side recess 11 in the opening 10 and in the illustrated position the pin 20 is located aside of said side recess.
- the horizontal element 2 With the wedge in this position the horizontal element 2 is positioned in the hook position illustrated in fig. 1, where the side opening of the hook element is in alignment with the yoke 3 of the vertical element, whereupon the horizontal element is displaced to the left such that the wall 7 of the hook element and/or the end portion of the wall 9 will bear against the vertical element 1.
- hooking takes place in that the horizontal element is lowered causing the hook part 7 to enter the space between the yoke 3 and the vertical element (see fig. 2)
- connection It is of course easy to release the connection by knocking the wedge upwardly and tilt it to the initial position shown in fig. 1 and it is thus so easy to carry out connection as well as disconnection that this operations can be carried out also by unskilled persons.
- the definition vertical element also includes parts which are fixedly secured to said elements.
- long sockets are used instead of yokes it is not necessary to have the wedge bearing directly against the vertical element since the wedge may bear against corresponding surfaces of the socket. In certain cases it is not necessary that the wedge bears against the vertical element above the yoke. It is also possible to have the pins 20,21 projecting in the same direction in which case the lower one projects more or has a bigger diameter than the upper one.
