Definitions
- the invention relates to a component for bed frames, underbeds or the like. From at least one wooden component and at least one plastic component firmly connected to it.
- Bed frames, lower beds or the like are usually made different components. So there is the real one Support frame often made of wooden parts, on which plastic parts, e.g. Bearing blocks, female connector caps, axle plates, etc. are attached. These plastic parts are commonly attached to the respective wooden part by means of screws.
- This way of producing bed frames, under beds or the like is relatively complex on the one hand, on the other are such screw connections depending on the quality of the wooden components used frequently, at least over a longer period Period, not very reliable, because the screws can easily tear out, so that the plastic parts no longer held securely on the wooden component in question are.
- the object of the invention is therefore to create a solution with such components from at least one Wooden component and at least one plastic component as possible simple, reliable and secure tightly together can be connected.
- connection hole of the wooden component if this, for example, as Bed spar is formed, continuously formed.
- the connecting pin is then longer than the hole depth and can be easily attached.
- the connecting bore the wooden component is designed as a blind hole, the inside end of which is accessible from the outside Cross opening opens into the wooden component.
- the transverse opening must then of course, be dimensioned so large that the Ultrasound probe can easily insert to increase the diameter the free end of the connecting pin to be able to manufacture the plastic component.
- the diameter increase of the connecting pin of the Plastic component can have different shapes.
- the diameter increase can be conical be formed or be formed as an undercut, e.g. in the manner of a lens head.
- the free end of the connecting pin with an additional cover cap is provided, which is also made of plastic and during the ultrasonic deformation at the same time on the connecting pin is attached.
- the component according to the invention can consist of different Plastic and wood materials are formed.
- Fig. 1 is first a wooden component in the form of a wooden spar 1 shown, the three differently designed has through connection bores 2a, 2b, 2c. there the connecting bore 2a is designed as a conical bore, the connecting hole 2b as a counterbored hole and the connecting hole 2c as a cylindrical hole.
- Such a wooden spar 1 is, for example, a spar Suitable bed frame, on the plastic bearing blocks, Female connector caps, axle plates or the like. Captive are to be attached to a component according to the invention manufacture.
- plastic components are shown by way of example in FIG. 2 and designated by the reference number 3.
- These plastic components 3 each have a connecting pin 4 on, which is dimensioned so that it in the respective connecting hole 2a, 2b, 2c of the wooden component 1 fits into it and with its free end 5 freely accessible from the respective Connection hole 2a, 2b, 2c protrudes.
- respective connecting pin 4 of the respective plastic component 3 by means of an ultrasonic deformation Enlargement of diameter in the area of the bore end held on wooden component 1.
- the increase in diameter takes place in each case in adaptation to the type of training the connecting hole. So she is adapting to the conical connecting bore 2a is also conical, this is indicated by the reference number 5a.
- the connection pin is adapted to the connection bore 2b this plastic component 3 conical in the end region formed, this is indicated by the reference numeral 5b and in adaptation to the cylindrical connecting bore 2b is the increase in diameter as a lenticular undercut 5c trained.
- the Connecting hole in wooden component 1 also as a blind hole be formed, this blind bore then opens into one of externally accessible transverse opening, preferably transverse bore of the Wooden component 1, in which a sonode for the corresponding Attachment of the free protruding in this area End of the connecting pin can be inserted.
- the Plastic component is then in the same way on the wooden component 1 held.
- the invention is not based on the illustrated embodiment limited. Other configurations are possible without leaving the basic idea. So they can Wooden components 1 made of any kind of wood or similar materials exist, the plastic components 3 can also be made any plastic materials, provided they are each have the required strength.
