EP3047887B1 - Toy vehicle excavator - Google Patents

Description

The present patent application takes the priority of the German utility model application DE 20 2015 100 264.5 to complete. The invention relates to a toy vehicle excavator according to the preamble of claim 1.

Such toy vehicle excavator are known for example from the DE 298 04 491 U1 and the US 2008/0207086 A1 , Another toy vehicle is known from the DE 196 00 440 C1 , which forms the closest prior art. The KR 20-2014-0005846 U discloses other toy vehicles.

It is an object of the present invention to develop a toy vehicle excavator such that a simple lowering of a raised excavator boom is possible.

This object is achieved by a toy vehicle excavator with the features specified in claim 1.

According to the invention, it has been recognized that a triggering actuator leads to a simple overcoming of a fixation of the excavator boom in a raised position. A player does not have to overcome greater holding forces, but it is sufficient a simple push button operation. After release of the locking device of the excavator boom is lowered due to its own weight. The trigger actuator brings when you press the latch hook out of engagement with the counter-latching body. The frame of the toy vehicle excavator may at least partially also be about its body.

An embodiment according to claim 2 has been found to be particularly useful. Alternatively or additionally, the triggering actuating element can also interact with the counter-latching body.

An actuating knob according to claim 3 can be easily operated.

An embodiment of the boom pivoting component according to claim 4 avoids the need for a biasing spring for the trigger actuator, which biases this in the starting position. The boom pivoting component itself transfers the firing actuator back to the home position.

An inclined surface according to claim 5 has been found to be particularly suitable for the safe return of the triggering actuator in the starting position.

At least one inclined surface according to claim 6 enables a safe and gentle contacting of the components of the locking device in the return to the lifting pivot position.

A suspension according to claim 7 can be produced by injection molding.

A cylinder according to claim 8 provides a realistic appearance of the excavator boom. The cylinder may be a double cylinder.

An accommodation of the locking device according to claim 9 hides this elegant. The closed housing may be an engine compartment or a motor housing of the toy vehicle.

A toy vehicle excavator 1 has a frame or a body, are mounted on the attachments. The toy vehicle excavator 1 is made entirely of plastic and is mounted from a plurality of plastic injection molded components.

The toy vehicle excavator 1 has a front-side excavator boom 2 and a rear-side excavator boom 3, the structure of which is not further deepened below.

At the end of the front excavator boom 2 as an attachment a spoon 4 is mounted.

Part of the front excavator boom 2 is a boom pivoting component 5, the detailed structure of which reveals the intrinsic details, broken representation Fig. 6 is apparent. The boom pivoting component 5 is between a z. B. in the Fig. 5 shown lifting pivot position with raised excavator boom 2 and one example in the Fig. 2 to 4 shown lowered pivot position with lowered front-side excavator boom 2 convertible.

The boom pivoting component 5 has as part of a latching device 6 a resilient latching hook. 7

The latching hook 7 serves to fix the excavator boom 2 in the lifting pivot position. In this fixation (cf. Fig. 6 ) engages behind the locking hook 7 a frame-fixed counter-locking body 8 of the latching device. 6

The toy vehicle excavator 1 also has a cooperating with the locking device 6 tripping actuator 9. The latter is used to switch the front excavator boom 2 from the raised to the lowered position. For this purpose, the triggering actuator 9 cooperates with the latching hook 7.

The trigger actuator 9 is designed as linear on the frame, namely on a motor housing 10, guided actuator button. The trigger actuator 9 is designed as a push-button operation.

The latching device 6 is housed in the closed motor housing 10.

The boom pivoting component 5 is designed to return, upon return of the boom pivoting component 5 from the lowering pivotal position to the lifting pivotal position, the triggering actuator 9 from a lowered, actuated operating position to a raised home position that actuates the trip Actuator 9 occupies before actuation. For this purpose, the latching hook 7 has an inclined surface 11, via which the latching hook 7 rests in the lifting-inclined position on the triggering actuator 9.

In addition, the counter-latching body 8 has a further inclined surface 12, via which the latching hook 7 comes into contact with the counter-latching body 8 when returning to the lifting pivot position.

The latching hook 7 is integrally connected via a leaf spring portion 13 with a base body 14 of the boom pivot component 5. The main body 14 is mounted on a pivot bearing 15 on the frame of the toy vehicle excavator 1, namely on the motor housing 10.

The main body 14 of the boom pivot component 5 is integrally connected to a double cylinder 16. The latter is extended with raised, front-side excavator boom 2 (see. Fig. 5 ), so that a piston 17 is visible, and retracted with lowered front-side excavator boom 2.

When playing, the front excavator boom 2 can be raised manually. In the lifting pivot position of the latch hooks 7 behind the counter-locking body 8, so that the front-side excavator boom 2 is fixed in the lifting pivot position. By pressing the trigger actuator 9, the latching hook 7, with which the trigger actuator 9 is in contact, displaced down until it disengages with the counter-latching body 8. Due to the weight of the front excavator boom 2 this then pivots down into the lowering pivot position. In this case, the pistons 17 enter the respective cylinders of the double cylinder 16. Upon return of the latching hook 7 in the lifting pivot position, the inclined surfaces 11, 12 of the latching hook 7 on the one hand and the counter-latching body 8 on the other hand come into contact and slide against each other. When lifting in the lifting pivot position, a lower actuating surface of the trigger actuator 9 slides on the inclined surface 11 of the coming in position latching hook 7 and is thereby raised to the starting position.
