Fig. 2 is the top view of the connecting element of Fig. 1;

Fig. 3 is the sectional view of the III-III line intercepting along Fig. 1;

Fig. 4 is the side view of the connecting element used of this connector element;

Fig. 5 is the side view of two interconnective Fig. 1 connector elements;

Fig. 6 A and 6B are the top view of the connector element that has been connected of Fig. 5 at two diverse locations;

Fig. 7 A and 7B then are the side views corresponding to other possible situations that are connected of Fig. 6.

Connector element 1 shown in Fig. 1,3 comprises two branches 2 that are perpendicular to one another and are mutually mirror image each other, the cross section of this branch takes the shape of the letter U basically, and have a terminal part 3 and an elastic locking lobe 5, terminal part 3 suitable insertions in hollow frame groove 4 grades, 5 usefulness of elastic locking lobe for this class groove of locking.This locking lobe 5 can introduction hole 6, for the usefulness of the state that unlocks.Each branch is provided with recess 7 at the corner part near connector element 1.As can be seen from Figure 3, the limit wall 8 of described recess 7 has two apertures 9 that are symmetrical in vertical midplane of branch 2 to lead to the cavity 10 of branch 2.

The wall section 11 that branch 2 is connecting recess 7 near outward edge 11 ' locate to form arc, and is pressed into decorative pattern or groove 12 at this curved portion at it, and this specifically as can see from Figure 3.Both each teeth are offset the half tooth distance each other.Each curved portion 11 ' radius equal half of axial spacing of each aperture 9.

Fig. 4 shows a connecting element 13 of being made up of the bridge member 14 that is provided with two parallel pins (promptly have strong market potential 15 and short pin 16).The axial spacing of described pin is equivalent to the axial spacing of aperture 9, and the thickness of pin then roughly is equivalent to the width of described aperture.Have strong market potential 15 terminal part 15 ' thinner, " then thicker, its thickness is the same with the start-up portion of pin 15 for its terminals 15.

This connecting element 13 can insert in the recess 7 together with having strong market potential obliquely and pass through aperture 9, because the cavity that adjoins 10 its bottoms are opening wide.In a single day bridge member 14 is in the top of recess, just can hold up pin 15 come, and make its moving axially along aperture 9.Retainer 17 can be with 15 " cooperate, and the position of the insertion of definite link or withdrawal.At this moment just can insert short pin 16 in the aperture 9 that adjoins.When disposing framework groove 4, its bottom 18 just can be in below the cavity 10, so the perk and can be from removal on the connector element of avoiding having strong market potential, and this pin still can move.

Fig. 5 and 6 shows two connector elements 1 that interconnect with connecting element 13, and in the connector element of 15 insertions of having strong market potential of connecting element, 16 of short pins insert in another connector elements.Because the axial spacing of pin 15 and 16 equals the axial spacing of aperture 9, and curved portion 11 ' radius equal half of described axial spacing, thereby each connector element can be around described pin 15 and 16 rotational, and the tooth 12 of described curved portion skew half tooth distance can be meshing with each other.Shown in Fig. 6 B, if with the direct reverse rotation each other of each connector element, then the tooth on the sidewall 12 can be to getting well.Like this, can the most easily insert the position of adjoining in the connector element aperture 9 to short pin 16.

At horizontal position shown in Figure 5, can insert second connecting element 13 when wishing so that shown in 13 of Fig. 6 A ' like that with as described in the position positively lock.

Obviously mode that can also be same is established another connector element 1 at the another side of each connector element of Fig. 5.

Fig. 7 A shows one of them connector element 1 has changeed an angle of 90 degrees afterwards by the situation that is connected of Fig. 5 and Fig. 6 B, and Fig. 7 B then shows the method that how to add the 3rd connector element when the position of Fig. 7 A.The 4th connector element also can add in the same way.

So just can constitute the space compound mode.If have only a connecting element 13 in the connector element 1, then can swing an angle of 90 degrees according to the hinge Placement, this wishes to swing an angle of 90 degrees when the framework each several part that is connecting is folded up for example adjoining wanting exactly.If want two frame part rigid interconnection, then available two connecting element 13 connect as shown in Figure 6.

In practicality, all establish a connecting element 13 in each recess 7, its short pin 16 inserts in another aperture 9, thereby described connecting element is coupled together with the mode and the connector element 1 that can not unclamp in fact.Will with have strong market potential 15 from the connector element removal to spend certain strength because in the cavity 10 and retainer 17 back 15 " can be in clamped condition, thereby ought not deposit under the situation of framework groove 4 yet, connecting element 13 can not lost.

Though each branch 2 among the figure is orthogonal, also can make this each minute draw different angles, even available hinge interconnects two branches of a connector element, makes them can get any angle.In addition, obviously the connector element 1 that is interconnecting among Fig. 7 can rotate each other, makes framework separately can get corresponding orientation, but also the connector element more than four can be interconnected.
