Description

The invention relates to a spring wood strip with a plastic cover for bed frames, the frame side parts of which have openings for receiving a projection

The wrapping of wooden slats with plastic has proven to be useful in order to To protect against the effects of moisture, which impair the spring properties of the strip or can be changed, which is naturally undesirable, since the spring wood wires are as constant as possible Suspension properties should have.

The spring wood slats, which are coated or enveloped with plastic by means of an extruder, are made according to their Completion so far at both ends with book-sen-shaped Provided brackets, which are made of plastic by the injection molding process will. These brackets are provided with lugs that fit into corresponding recesses in the bed frame side parts can be used, whereby the individual spring wood slats are attached to the bed frame.

The object of the invention is to fix such plastic-covered spring wood slats on the bed frame to be able to do this much easier and, in particular, faster.

In the case of a wooden slat with plastic covering for bed frames of the type described above This object is achieved according to the invention in that the approach is directly on the plastic casing Spring wood strip is formed.

Due to this training, there is a single operation for the wrapping of the spring strip, d. H. the Separate manufacture of the two-end brackets is not required, and especially their attachment to the Spring slats, so that the assembly of a bed frame with spring wood slats and significantly simplify can accelerate.

In addition to the attachments that can be inserted into the frame side parts, it is advisable to have an additional stop surface to form the plastic envelope, which interacts with the bed frame side part from the outside. on Because of this training prevents the approaches used in the bed frame side parts when The spring-down of the wooden slats is stressed too much and sheared off, as in principle with separately manufactured brackets for spring wood slats is known.

It is also useful between the front ends of the wooden slats and the plastic casing each a buffer made of easily compressible

> o Material, e.g. B. soft foam to be arranged, whereby achieved is that the spring wood core can elongate under its load without affecting the end parts of the plastic casing to exert too strong horizontally directed forces, which in the openings of the bed rail

% 5 approaches used on the side could shear off.

The invention is explained in more detail below with reference to the drawing, for example. This shows in
F i g. 1 a spring wood strip according to de: invention in

ao a vertical longitudinal section and in

Fig.2 shows a bearing end of a spring wood strip according to. ^{1 of} the invention in the inserted / th state in a frame side profile.
The total of 1 designated spring wood strip be

a5 consists of a spring wood core 2 and a plastic casing 3, which is shaped like a bearing body at each end of the spring wood core 2 , in particular barb-like projections 4 being formed which engage in corresponding openings 5 of a frame side part 6.

The end of the plastic casing 3 is also formed into an outer stop 7 that of the upper one in FIG neren corner of the frame side part 6 rests and the sentences 4 when loading the wooden slat against shearing secures.

Between the front end of the spring wood core 2 and the plastic casing 3, a buffer 8 is easy compressible materia !, for example soft plastic foam, arranged, for example, in front of the wrapping of the spring wood core 2 with plastic the relevant end face of the spring wood core can be glued on. This buffer is used for the Load the spring wood strip occurring elongation of the same to absorb without affecting the end of the bearing too strong horizontal forces are exerted on the plastic casing 3, which shear off the lugs 4 could.

In order to keep the plastic consumption within limits, the plastic casing 3 can be made of foamed plastic, preferably a polyurethane foam, provided that the composition is chosen such that sufficient dimensional stability or strength is ensured at the bearing ends.
The bearing ends of the plastic casing 3 can also have differently designed approaches or stop surfaces. For example, a web adjacent to the outside of the frame side part 6 could also extend downwards from the outer end, or lateral openings could also be formed in the frame side part 6, into which the shoulders at the bearing end of the plastic casing extend, similar to that of separately manufactured bearing bodies is known for slats of wood.
