Description

[Detailed description of the invention] plus deck frame The present invention relates to a support frame and components for the frame in more detail. The invention relates to support frames suitable for furniture and their components. It is not limited to.

In recent years, plastic bars, eaves and connection joints or fittings have been Furniture with built-in support frames has become increasingly popular, especially as outdoor furniture16. It is also gradually gaining popularity as furniture for the prefecture. This kind of furniture is often purchased It is sold as a kit consisting of bunny y to be used as vl and rl by the right. Ru. Before the adhesive hardens, place each joint accurately in the pipe and align the pipes. Make sure the opposite end is in the correct position for the rest of the frame. Of course, it is important to In many cases, the connection di must be oriented exactly 906 with respect to the pipe. Of course, for example, connect Join [- or 90 if you don't support the rat to 11 no singes 1 Angles other than 6 may be required.

An inexperienced person may connect the pipe with a slight deviation from the body. It is not possible to attach it at a different angle (it is possible to do so once the adhesive has hardened). Once this happens, it is extremely difficult or even impossible to correct this error. So However, due to a small error in the installation of various connection joy > (-), it is unusable. Noh and/or.

Other disadvantages of the support frame formed by the installation of plastic pipes are , the pipe is inserted into the socket 1- in the connection shop, so each Appearance 1 - Unsightly discontinuities or stubs remain on the frame at the hem. At the point.

While the above discussion is directed only to frames for furniture, the present invention also applies to frames for shops. It can be similarly applied to display frames, shelf materials, etc.

A first object of the invention is to eliminate inaccuracies in assembly and preferably to avoid unsightliness. Frame that avoids the problem of discontinuity +, (l aro,.

According to the present invention, a plurality of substantially elongated hollow members having substantially symmetrical cross sections; a plurality of at least two spigots sized to be inserted into the member; With connected members of At least one longitudinal groove on its outer surface in angular relation is a spline. 1-C and the inner surface of ζA (2 longitudinal strips) Prine Mata 1. It has an L groove and cooperates with the groove or spline of the groove 1-. Provides a frame that has been made in various ways for various purposes.

Preferably, the spigots are tangent to their outer peripheries at an angle of 90' with each other. Four grooves or splines are formed that coincide with the predetermined longitudinal axis of the connecting member. Ru.

The external shape of the long hollow member is such that the connecting Preferably, the external shape is the same as that of the main body. If it is 1 like this, the outside of the connected member Since the surface and the outer surface of the attached hollow member are substantially continuous, it is possible to Eliminates ugly discontinuous shapes.

If necessary, the particularity of the frame to be assembled from hollow members and connecting members. To meet the requirements, the grooves can be cut to 45°, 22.5° or other desired. Placed at an angle, it can be covered.

Most preferably, the elongate hollow member is tubular.

Although it seems that a pipe with only one positioning spline would be practical enough. , two or More splines may be provided.

The tubes and connecting members are optimally molded from PVC or other suitable plastic material. and fixedly connected using a suitable adhesive. However, if consisting of a tube, Alternatively, the connecting member may also be formed from cast or extruded aluminum, wood, etc. In these cases, any suitable connection method can be used.

The connecting members can be optionally used to form the desired connection between adjacent tubes of the frame. 1. In the case of a house, Kamogawa frame, the shape can be multiplexed on the connecting member. Several scales are usually located 90' from each other. Connection member type Preferred examples of each are detailed below.

As is clear from the above description, a long frame is created by providing a spigot 1-1. By cooperating the spline inside the frame 1 with the groove, the frame is The risk of the components being incorrectly placed with respect to each other is substantially reduced and Many components were also assembled by people. As mentioned above, The most common error during assembly is to move the flange slightly out of the required 90' position. This is completely prevented by the present invention. It will be done.

In addition to the generally elongated hollow member and connecting member detailed above, the present invention We also offer kits of frame construction parts, including appropriate instructions for their assembly. This is what we provide.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the drawing: FIG. 1 is a perspective view of a first example of a connecting member embodying the invention; FIG. 2 is an end view of the connector showing the groove in the spigot; Figure S) A is a perspective view of one end of a frame tube embodying the present invention. ; 3-9 are perspective views of other connecting members embodying the invention: FIG. 10 is a perspective view of a table using a frame according to the invention: FIG. 11 shows the table shown in FIG. 10 from a kit of components according to the invention. The assembly instructions for assembling the module are shown.

As shown in FIGS. 1 and 2, a connecting member embodying the invention comprises a central body It is provided with a generally tubular member having a central body part 1, each having a recess. Two spigots (SDiQOt) 2.3 are extended. on each spigot is formed with four grooves 4 extending in the longitudinal direction, and the valley groove 4 is formed in the spigot 2.3. Each spigot 2. 3 is provided with a slight chamfer 5, which allows the connection member 1 and the It is easy to connect with other frame constituent members formed like the tube 6. ing.

As can be seen from FIG. 2A, the frame tube 6 includes a An inner spline 7 is formed extending over the length thereof. flame Tube 6 preferably PVC, more preferably UV cured or stabilized PVC Extrusion molded by Similarly, connecting member 1 can be made of similar grade UV-cured or is injection molded into a stabilized type PVC.

Advantages of a grooved spigot and associated splined tube will become clearer from the diagrams shown in FIGS. 3 to 9. this In the example shown in the figure, Subigotsu 1-2.3 is a seed from the central body part 1 of the connecting member. They extend at different angles. In the example shown in Figure 3, the connecting member is a right-angled connector. It becomes. Figure 4 shows a T-shaped connector, with the right-angled 7] neck in Figure 3. It has a shape in which an arm and subigotsu 1 to 8 connected to the arm are added to the arm. . In the example shown in FIG. It extends in the opposite direction to spigots 1-2 and perpendicular to spigots 3 and 8. Figure 6 In the example shown in , the arm and the subigotsu 1 to 10 connected to the arm are It extends perpendicularly to the piggot 2.3. In the examples shown in Figures 7, 8 and 9, , the added arm and the spigots 11, 12 and 13 connected to the arm They are equipped as shown in each figure.

The connecting members shown in Figures 3 and 4 are most commonly used in the construction of furniture frames. It is something that can be done. Typical daple with support room according to embodiments of the invention are shown in FIGS. 10 and 11. As understood from FIG. 11, as shown in FIG. The table is 9 tubes 6.4 direct procedure amendments (mouse) Showa. . January, stomach.
