See accompanying drawing now, Fig. 1 particularly, design first joint 1 and connect two first struts 2 and two second struts 3 securely, and two first struts 2 point-blank extend and two second struts 3 extensions point-blank each other basically basically, and are substantially perpendicular to two first struts 2.

Each first strut 2 have a pair of qualification tongue-and-groove from the outward extending tongue 4 of an end.Each tongue 4 extends to surperficial concordant with separately strut 2, and each extends parallel to each other to tongue 4, between spaced slot 5.

Each second strut 3 has from the outward extending tenon part 6 of an end.Described tenon part 6 have and the tongue 4 of first strut 2 between the thickness that roughly adapts of slit 5, and each tenon part 6 basically with the center line of separately second strut 3 on a line.

As shown in Figure 2, each can produce contact to tongue 4, limits tongue-and-groove 7 between them.Tongue-and-groove 7 has constant elongated rectangular section, and along first strut 2 extension from start to finish that connects.The shape of tongue 4 makes corresponding tongue 4 install along seam 8 exactly, forms the right wall of continuous phase of tongue-and-groove 7.In shown special joint 1, tongue 4 shapes paired on each first strut 2 are identical, and each stops with the surface of contact with ogee profile, and form the seam 8 of ogee or shallow serpentine.

Very clear, the monolithic entity that is formed with tongue-and-groove 7 thereon can substitute two first struts 2, although this can reduce the multifunctionality of joint 1.

As shown in Figure 3, tenon part 6 can be inserted tongue-and-groove 7 from the end opposite of tongue-and-groove, second strut 3 is connected on first strut 2 of connection.Under the situation if any tongue 4, the shape of tenon part 6 makes them accurately be installed together in tongue-and-groove 7.And preferred tenon part 6 shapes are identical, and each stops with the surface of contact with ogee profile.Therefore, as shown in Figure 4, two tenon parts 6 (with dashed lines representative here) are complete filling tongue-and-groove 7 together.

In case after being assembled, designing various structures joint 1 kept together.For example, the layer of adhesive that limits on each contact surface of the tongue 4 of tongue-and-groove and tenon part 6 is firmly held in together joint 1, if particularly tenon part 6 and the area of contact that forms between the tongue 4 of wall of tongue-and-groove 7 are very big.

Yet such structure does not allow to dismantle at an easy rate joint 1.In many different structures (for example, bottle stand), have many structures to be mounted, and people may need to reinstall these structures.People also may need to dismantle this structure to be used for storage or transportation, and then assemble up apace.

Fig. 5 a and 5b illustrate the component (for clarity sake omitting in Fig. 1～5) of described joint 1, and it allows joint to be assembled securely, under the prerequisite of not losing fastening force, dismantle in a plurality of places according to wish then.One of them of a pair of tongue 4 of the qualification tongue-and-groove 7 that extends from each first strut 2 has two holes that pass therethrough, the root of a contiguous tongue 4 and its tip of vicinity.The tenon part 6 of each second strut 3 is provided with root and its tip of vicinity of 10, one contiguous tenon parts 6 of two posts.Limit tongue-and-groove 7 when connecting tongue 4, and tenon part 6 is when being inserted laterally wherein, post 10 engages so that joint 1 is locked together with hole 9 accordingly.Post 10 on each tenon part 6 is connected with the hole 9 of the root of contiguous tongue 4 and near the most advanced and sophisticated hole 9 of another connected tongue 4.Therefore, each tenon part 6 is fastened on each porose tongue 4, and vice versa.

Shown in Fig. 6 a, although the use that can come equivalence according to the convenience of for example making only towards the groove of 5 openings of the slit between tongue 4, most convenient be that hole 9 penetrates each tongue 4 fully and extends.Shown in Fig. 6 b, preferred post 10 is shallow conical butt, and its ramp surface makes tenon part 6 and post 10 pass through slit 5 between the tongue 4 at an easy rate, and for more direct installation, helps the location and the centering of post 10 9 inside in the hole.

This fastening structure be particularly suitable for strut 2,3 or the parts similarly made by materials such as plastics material tough and tensile, elastically deformable between joint 1.This makes and to insert slits 5 or from the slit during 5 withdrawals, post 10 can be outwards mobile tongue 4 elasticity when tenon part 6.The parts of shown joint 1 also are particularly suitable for injection molding production.

When using other structural material, the special tangent bend shape of the tongue 4 of first joint 1 and tenon part 6 may be not easy to produce, can be preferably as shown in Figure 7 second joint 11.In this example, the tongue 4 (with the tenon part of can't see in this view 6) that limits tongue-and-groove has simple rectangular section, is only comprising formation seam 8 between the corresponding tongue 4 of straight line.Tongue-and-groove 7 have with first joint 1 in identical shape, and the tenon part 6 of rectangle is filled tongue-and-groove 7 side by side.Though this shape of tongue 4 may not have the shape of described first joint 1 beautiful, it is than being easier to use-case such as wood material is produced.

As described first joint, 1, the second joint 11 can tighten together its parts with attachable post 10 and hole 9 (see among Fig. 8, when when the direction opposite with Fig. 7 seen, the final profile of second joint 11).But, when using the relatively poor material of elasticity (for example most of forms of wood), can use screw, nail, pin or analog tighten together joint 11.For example, each can be bored to tongue 4 and two tenon parts 6 in the hole 9 of alignment, and is being with or without under the situation of Bond, and the pin of suitable diameter is inserted wherein.Therefore as shown in Figure 8, show four holes 9 that are square and arrange on each opposite surfaces of second joint 11.

For the material that is difficult for making tongue 4 resiliently deformables, metal for example also can design post 10 and flexibly be installed on separately the tenon part 6, for example, is installed in the boring with spring, in case post 10 aligns with hole 9 separately, they will be outstanding from boring.

Also post 10 can be positioned on the tongue 4, extend into slit 5, and hole 9 (or groove) passes 6 extensions of (or advancing) tenon part.Also can be many other structures detachable or permanent locking between tongue 4 and tenon part 6, but wish all that in all cases each tenon part 6 directly is fastened on each on the tongue 4, and vice versa.

The 3rd joint 12 is shown in Figure 9, and wherein the shape of tongue 4 (with sightless tenon part 6) makes them come their counterpart of butt along simple linear joint 8.Therefore, each tongue 4 is half of the tongue-and-groove 7 that is limited by it of extend through only, and each tenon part 6 is only passed described tongue-and-groove 7 half.Though the 3rd joint 12 may be enough in some occasion, may it be like that firm and reliable not as first and second joints 1,11, tongue 4 and tenon part 6 are long in first and second joints.

The example of the structural member that enough described first joints 1 of energy (perhaps may be second joint 11) shown in Figure 10 are secured together.Cross-shaped part 13 comprises two in the elongate rod 14 of the quadrature of midpoint crossing separately.First bar 14 is provided with the tongue 4 of a pair of qualification tongue-and-groove, and tongue 4 is from each remote extension, and second bar 14 is provided with the tenon part 6 from each remote extension.As above-mentioned first joint 1, tongue 4 and tenon part 6 have the ogee profile.Therefore using wherein, the tongue 4 of the qualification tongue-and-groove of two cross-shaped parts 13 and 6, four such cross-shaped parts 13 of tenon part of two other cross-shaped part 13 can be joined together.Such cross-shaped part 13 can be used as single plastic injection piece production.

Therefore as shown in figure 11, can use any cross-shaped part 13 that needs quantity, by joint 1 four adjacent parts 13 being linked together makes up lattice structure 15.By attachment post 10 and hole 9 and kept together loosely, provide additional stability at the part joint 16 of the periphery of lattice structure 15.They also can be used as the leg of lattice structure 15 on stayed surface 17.

Except shown direction, lattice structure 15 defines many diamond-shaped windows 18, if preferred words can also be orientated, and the bar 14 vertical and horizontal alignments of each cross-shaped part 13.

As shown in Figure 12, bottle stand 19 is application of the lattice structure 15 that can assemble fast.This comprises two adaptive vertical lattice structurees 15 that are connected to form by some horizontally extending steel poles 20 (seat that holds bar 20 is molded in the cross-shaped part 13, but for clarity sake omits) from figure.For example, described shelf 19 is of a size of burgundy bottle and can passes the window 18 of a grid 15 and be inserted into, and is supported on two adjacent level bars 20.The modular nature of described grid 15 makes that shelf 19 can be extended according to wish, repacking again, even reduces size, and the stability of joint 1 allows relatively, and lighter shelf 19 supports a lot of bottles safely.

Though cross-shaped part 13 is depicted as simple cross shaped head, as long as be provided with four vertical outward extending attachment portions 4,6 it is connected on other parts 13 in the same structure, the artificer can freely design any desirable shape.

Shown in Figure 13 a～13c, joint 1,11,12 also can be formed by the parts that only have two attachment portions 4,6.First supporting part 21 comprises the single elongated member (, for for simplicity, the rectangle tenon part 6 of second joint 11 being shown here) with tenon part 6, and tenon part 6 is from each remote extension.Second supporting part 22 comprises the single elongated member with the tongue 4 that limits tongue-and-groove, and the tongue 4 that limits tongue-and-groove is from each remote extension.Therefore, two first supporting parts 21 and two second supporting parts 22 can be joined together to form joint 11, and each supporting part 21,22 can participate in another such joint 11 at their far-ends separately.Therefore, can make up to Figure 11 in similar grid 15; They comprise the joint of twice, but the versatility that increases becomes advantage in some applications.

In fact, shown in Figure 13 c, the 3rd supporting part 23 can be all structures that are used for making up grid 15 or analog structure, and described the 3rd supporting part 23 has the tongue 4 of the qualification tongue-and-groove that a pair of first end from slender member extends and the tenon part 6 of extending from second end away from described first end.Although need extra care to guarantee that two tenon parts 6 and two pairs of tongues 4 are provided for each joint 11 to be made in assembly process, this has reduced the quantity of producing different structure spare.

Shown joint 1,11,12 can be used in other structure that needn't form grid 15.Example shown in Figure 14, its central sill 24 is provided with three tongue-and-grooves that pass therethrough 7.Two panels 25 are all along being provided with three tenon parts 6 with corresponding interval on one side.Tenon part 6 is inserted each tongue-and-groove 7 by the opposition side from beam 24, fills tongue-and-groove 7, and forms three joints 11 that are locked in the appropriate location by above-mentioned any structure.Therefore, panel 25 is fixedly mounted on the beam 24.

Therefore, joint 1,11,12 is very general, and can design them in the various structure that is applied to except that said structure.
