Definitions

• the invention concerns a swing arm for a toy building set and consisting of two parts, the first part of which being adapted to be connected with an object, and the second part being swingably journalled to a holder.
• the present invention provides an element giving the children new possibilities of constructive and func ⁇ tional play.
• a rotary movement as well as a translatory movement and combinations thereof may be imparted to the coupled object.
• the telescopic cooperation of the first part and the second part of the swing arm permit pivotal movement with various radii about the pivot, and this makes it possible when per ⁇ forming work to avoid inexpediently great force and moment loads in the pivot. This is an advantage since constructions built with building parts from a toy building set often have a limited strength.
• the coupled object may e.g. be lifted above an edge and onto a horizontal face on which the swing arm is hinged.
• Claims 3 and 4 define expedient constructions of the swing arm.
• the swing arm is constructed to be movable by cooperation between the holder and the first part of the swing arm, it is obtained in a simple manner that this cooperation can perform the telescopic movement as well as the pivotable movement.
• This coop- eration may expediently take place by a cord drive, as stated in claim 7.
• Claim 6 states that the movement of the swing arm takes place by cooperation between the holder and the second part of the arm. The movement is thus a pure pivotable movement.
• Claims 7 - 9 separately provide advantageous ways of controlling the movements of the swing arm.
• the elastic force may here be a pull force or a compressive force.
• fig. 1 shows a toy car with a swing arm according to the invention
• fig. 2 is a perspective view of a swing arm according to the invention
• fig. 3 shows a swing arm according to the invention with an embodiment of force transmission
• fig. 4 shows a swing arm according to the invention with another embodiment of the force transmission.
• Fig. 1 shows a swing arm with a first part 1 and a sec ⁇ ond part 2.
• the second part of the swing arm is swing- ably journalled at a hinge 6 to a chassis 3 of a toy car.
• a pulley 4 with a cord is provided on the chassis, said cord being connected at its outer end with the first part 1 of the swing arm.
• the first part 1 of the swing arm has a part 7, which is telescopically movable in the second part 2 of the swing arm, and a part 8 forming a right angle with the part 7 and being formed at its free end with a hook 9.
• a cord 31 is connected with the second part of the swing arm, and a tension spring 32 is provided between the cord 31 and the chassis 3.
• the cord 31 and the tension spring 32 may be replaced by an elastic rub- ber- band.
• a tension spring 33 which may also be replaced by an elastic rubber band, is provided be ⁇ tween the first part 1 of the swing arm and its second part 2.
• the swing arm can pivot about 180° about the hinge 6, so that the hook 9 assumes a position which is lower than the upper side of the chassis 3, in which position it may be coupled to an object standing on the base.
• the object may e.g. be a container 10 to be lifted onto the chassis 3 of the toy car.
• the swing arm is pivoted back, and the hook lifts and carries the container 10. After the swing arm has completed its pivotal movement, its first part 1 with the part 7, is pulled telescopically out of the second part 2 by a translatory movement.
• Fig. 4 shows another embodiment of the force transmis ⁇ sion between the chassis 3 of the toy car and the swing arm.
• a cord 41 is here passed through the upper part of the second part 2 of the swing arm and is connected with the part 7 of the first part 1 of the swing arm.
• the force from a spring 42 is not transferred directly to the second part 2, but to the first part 1, and thus has the same function as the parts 31, 32 and 33 in fig. 3.
• the spring 33 in fig. 3 is here described as being a pull spring.
• a compression spring may be used instead of a pull spring.
• the part 7 of the first part of the swing arm has a res ⁇ ilient hook 11 near its free end, said hook serving as a snap lock together with an edge 12 on the second part 2 of the swing arm when assembling the first part and the second part.
• the hook 11 and the edge 12 serve as end stops so that the two parts of the swing arm remain assembled.
• the movement of the swing arm takes place by means of a cord drive and spring forces.
• these movements may be performed by means of stiff shafts, gearwheels, chain drives or the like.
