Description
SPECIFICATION
A connector for a framework structure
This invention relates to a connector for connecting together elongate members whereby a plurality of such connectors can be used to connect together elongate members to form a framework structure and particularly but not exclusively a geodesic structure such as a geodesic dome.
The invention resides in a connector for connecting together elongate members, comprising two parts, each of which has a plurality of equi-angularly spaced recesses in a major face thereof, a plurality of connecting members, each having a pivot member at one end for being received in a pair of aligned recesses in the two parts and a projection at the other end for receiving a tubular end portion of an elongate member, each connecting member being pivotably adjustable relative to the two parts in a plane transverse to the aforesaid major faces, and means for fastening the two parts together with the pivot members of the connecting members held captive therebetween.
The two parts may or may not have an intermediate part therebetween. If they do the recesses will be shallower than if they do not and the intermediate part will have a plurality of equi-angularly spaced sockets, equal in number to the number of recesses in each of the first mentioned two parts, for receiving the pivot members of the connecting members.
The pivot members may be of spherical or generally cylindrical shape.
The projections may be of frusto-conical or prismatric shape for receiving as a push-fit thereover tubular end portions of the elongate members.
The fastening means may be for example a nut and bolt, or a rivet or a snap-fittable fastener.
Conveniently, the connecting members are each pivotably adjustable relative to the two parts only in a single plane transverse to the aforesaid major faces.
The two parts could be metal pressings or could be formed by injection moulding or die casting. If provided the intermediate part could be an extrusion. The connecting members could be injection mouldings or die castings. If injection mouldings, the connecting members for the connector may be integrally connected by a flexible sprue.
The invention also resides in a framework structure comprising a plurality of elongate members connected together by the connectors.
The invention will now be more particularly described with reference to the accompanying drawings, in which:
Figure 1 is an exploded view of one embodiment of a connector according to the invention,
Figure 2 is a side view of one of the connecting members of the connector shown in Fig. 1,
Figure 3 is an exploded view of part of an alternative embodiment of a connector according to the invention, and
Figure 4 is an exploded view of another embodiment of a connector according to the invention.
Referring firstly to Figs. 1 and 2 of the drawings, the connector shown therein comprises two plate like parts 10 and 11, which are circular when viewed in plan. The parts 10 and 11 may be injection moulded in plastics material, die-cast in metal, or pressed from metal plate. Each part 10, 11 has five equi-angularly spaced part spherical recesses 1 2 in a major face thereof. The recesses must each define less than a hemi-sphere. Each of the parts also has a central aperture 1 3 and a collar 14 may surround the aperture and extend from that major face of the part opposite to the major face in which the recesses 1 2 are formed.A groove 1 5 extends radially from the outer edge of each part 10, 11 and into the wall of each recess 1 2 for a purpose which will become apparent hereinafter.
The connector also comprises five connecting members 1 6. Each connecting member 1 6 comprises a ball 1 7 at one end connected by an arm 18 to a slightly frusto-conical hollow projection 1 9 at the other end. The taper on the projection 1 9 is towards its free end and is such that the projection can receive, preferably as a push or interference fit, an elongate member in the form of a tube (not shown).
The balls 1 7 are dimensioned so as to fit into sockets defined by a pair of aligned recesses 1 2 in the two parts 10 and 11.
Means are also provided to fasten the two parts 10 and 11 together with the balls 1 7 of the connecting members clamped therebetween. As shown in Fig. 1 the fastening means is in the form of a threaded bolt 20 and nut 21, the bolt extending through the apertures 1 3 in the two parts 10 and 11.
However, the fastening means could be in the form of a rivet or a snap fittable fastener.
The projection 1 9 of each connecting member 1 6 also has an aperture 22 therein for receiving a rivet to secure a tube thereto.
However, it is believed that this is by no means essential and may be required only for certain applications of the connector.
The aforementioned connector is particularly designed for connecting together tubes to form a geodesic structure such as a geodesic dome. The balls 1 7 of the connecting members 1 6 are placed in respective sockets defined by two aligned recesses 1 2 of the parts 10 and 11 and the parts 10 and 11 are loosely fastened together by the bolt 20 and nut 21.The marginal portions of aligned pairs of grooves 1 5 in the two parts 10 and 11 prevent adjustment of each connecting member in all but one plane relative to the parts 10 and 11, this plane being normal to the major surfaces of the parts 10 and 11 and for each connecting member 1 6 passing diametrically through the parts 10 and 11 and bisecting the respective recesses 1 2. However, the angle at which each connecting member 1 7 projects from the parts 10 and 11 in the aforesaid plane can be adjusted and the bolt and nut then fastened tightly to rigidise the connector, that is to say, to clamp the balls 1 7 in their respective sockets to an extent where they can be moved only by applying a certain force to the connecting members.The tubes can be connected to the projections 1 9 before or after tightening the bolt and nut and a geodesic structure can be built up gradually.
The size of the connectors and tubes can be varied such that at one end of the scale they can be used for educational purposes or toys and at the other end of the scale can be used for building large marquees or indeed for building structues in outer space.
The connectors may have more or less than five connecting members 1 6 and a corresponding number of recesses 1 2 in each of the parts 10 and 11 and may be used for making other than geodesic structures. For instance, they can be used to form the outline of a regular solid or to form a space frame.
If the connecting members are injection moulded in plastics material, they could be integrally connected by a sprue, the cross sectional dimensions of which would be small enough to render the sprue flexible and provide for the appropriate degree of relative movement between the connecting members of each connector.
The elongate members, need not necessarily be tubes but instead may have tubular sockets at each of their ends.
Fig. 3 shows an alternative embodiment in which the parts 10' and 11' have shallower recesses 12' than the recesses of the embodiment shown in Fig. 1 and in which an intermediate part 23, which may be in the form of a plastics extrusion, is arranged between the parts 10 and 11. The part 23 has a central aperture and a plurality of sockets 24 corresponding in number to the number of recesses 12' in each of the parts 10' and 11'.
In this embodiment it is not necessary to provide grooves (similar to grooves 1 5 of the embodiment shown in Fig. 1) in the parts 10' and 11'.
Referring now to Fig. 4 of the drawings, the connector shown therein comprises two parts 10" and 11", which are polygonal, e.g. hexagonal, when viewed in plan. The two parts 10" and 11" are injection moulded in nondeformable plastics material. The outer face of each part is generally planar. Six equi-angularly spaced recesses 12" are defined in the inner face of each part 10", 11" by an integral peripheral flange 25 around the part 10", 11" and integral ris 26 upstanding from the inner face of each part 1 0", 11". Each of the parts also has a central aperture 13". A slot or groove 15" extends radially inwards from the centre of each of the side edges of each part and terminates approximately in the middle of each recess 12".
The connector also comprises six connecting members 16" which are also injection moulded in non-deformable plastics material.
Each connecting member has a generally cylindrical pivot member 17" at one end connecting by an arm 18" to a prismatic projection 19" at the other end. The projection 19" is as shown of generally triangular cross-sectional shape but could be of other appropriate shape. The projection 19" can receive as an interference fit, an elongate member in the form of a tube of deformable plastics material or having deformable plastics sockets at its ends.
The pivot members 17" are dimensioned so as to fit into sockets defined by a pair of aligned recesses 12" in the two parts 10" and 11" and the slots or grooves 15" are dimensioned so as to receive the arms 18" of the connecting members 16" and permit pivotable adjustment of the connecting members 16" relative to the two parts 10" and 1 1".
The parts 10" and 11" are fastened together by a bolt 20" and nut 21" and the connector is assembled in similar manner to the connector of Figs. 1 and 2.
Similarly to the connector of Figs. 1 and 2, the connector of Fig. 4 may have more or less than six connecting members 16" and a corresponding number of recesses in each of the two parts 10" and 11" and may be used for making geodisic or other structures on any appropriate size scale.
The connector shown in Fig. 4 could be die cast in for example aluminium instead of being moulded in plastics material.
