Abstract
Description
- Spacial structures that comprise a number of sections whose ends are joined to a number of knuckles to make reticular spacial structures are known.
- In particular, the spacial structure whose knuckles are comprised of solid balls to which tubular sections are joined is known.
- The spacial structure whose knuckles are comprised of two spherical shells joined together by means of external fins is also known.
- The chief drawback with the first of the aforementioned systems lies in the difficulty on site with joining the tubular sections to a solid ball, and so it can only be worked on from the outside.
- The second of the systems mentioned presents the serious difficulty of the fins for joining to the spherical shells, which imposes enormous restrictions upon the reticular assembly of the relevant tubular members.
- The purpose of this Patent overcomes these disadvantages by developing a knuckle that is comprised of two internally hollow parts with no outside protrusions to restrict reticulation.
- The spacial structure covered by this invention, which is comprised of equidistantly positioned knuckles, an assembly of sections and means.for joining these sections at each end to said knuckles, is peculiar because it is made up from:
- a) a first hollow base piece whose external shape is approximately that of a spherical shell in which there is a number of equidistantly positioned holes at an angular distance of a and with a perimeter area that is bent towards the inside,
- b) a second hollow base piece whose external shape is approximately that of a spherical shell in which there is a number of equidistantly positioned holes at an angular distance of a ,
- c) means of linkage between the first base piece and the second base piece which, upon being joined together, form the knuckle of the special structure, with all the holes being equidistantly positioned with respect to one another at an angular distance of a .
- It is also peculiar because the second base piece possesses a bent perimeter area facing the bent area on the first base piece, making a joining area.
- It is peculiar too because the bent area on the second base piece faces outwards.
- It is also peculiar because the bent area on the second base piece faces inwards.
- It is peculiar also because the means of linkage between the first base piece and the second base piece comprise a strength member in internal contact with the poles of both spherical shells, and means for tightening the strength member up against the poles.
- It is peculiar too because the means for tighte- ning comprise a stud which running through the middle of the strength member, goes through both spherical shells, and has a stop on one end, and a thread for tightening on the other.
- It is peculiar moreover because the means of linkage between the first base piece and the second base piece are comprised of threaded screws at the joining area.
- It is also peculiar because one of the base pieces possesses protrusions which engage inside grooves provided for the purpose in the joining area upon the other base piece.
- It is peculiar too because the means for joining the sections to the knuckles are comprised of:
- a) a single-piece element with inside thread and rigidly attached to the section to be joined, and with its face supported upon the outer wall of a base piece.
- b) a pressure screw whose head rests against the inner wall of a base piece and whose body, after going through one of the equidistantly positioned holes, is threaded into the single-piece element.
- It is peculiar furthermore because the contact areas between the single-piece element and the base piece, and the screw head and the base piece are spherical.
- It is also peculiar because the single-piece element in revolution has at least one side surface which is shaped like a conical frustrum.
- In order to provide a.better understanding of the in vention, drawings are attached to show a preferred practical construction thereof, this being subject to those minor alterations which do not affect the basic features, and wherein:
- Figure 1 is an elevational view of a knuckle as covered by the invention, where the lower base piece joining area covers the equator of the knuckle, and where the screwed attachment between the two parts is effected upon said equator.
- Figure 2 is a section of the screwed attachment when same is effected..below the equator.
- Figure 3 is a section of a knuckle where the screwed attachment is effected on the flat part of the joint area.
- Figure 4 is a section showing the joining of the two base pieces by means of protrusions.
- Figure 5 is a section of the joint between a section member and a base piece.
- The knuckle is comprised of two base pieces (1) and (2).
- Generally, base piece (1) is larger than base piece (2), giving an asymmetrical joint, but it is perfectly fea sible for both pieces to be practically alike.
- The outside shape of the two base pieces is that of a spherical shell in order that its external form in the coupling is approximately a sphere.
- Holes (3) provided upon each of the spherical shells are equidistantly positioned with respect to one another, and there is an angle al between the adjoining edges of the different spherical shells when they lie together. (See Figure 3).
- These holes (3) form part of the joint between the spacial knuckle and sections (6).
- Said angles al can be altered for each knuckle and each different structure.
- The first base piece (1) possesses a perimeter area (12) which is bent upon itself and is provided with open holes (13) which are preferably threaded.
- Said holes (13) form part of the joint between the two base pieces (1) and (2).
- The other base piece (2) possesses in turn a lip (21) into which engages the lip (12) provided on base piece (1).
- In these drawings, the lip (21) is shown as engaging externally with lip (12), but'the invention also includes the idea wherewith lip (21) is given a similar shape to lip (12), so that the two can engage together by means of protrusions like those depicted in Figure 4.
- Base piece (2) is provided with slots (21 bis) which facilitate the engagement and joining with sections (6).
- Base piece (2) is furthermore provided opposite the holes (13) on base piece (1), with open holes (13 bis), and joining screw (5) is housed in said holes (13) and (13 bis).
- Base piece (2) is moreover provided with protrusions (30) which engage in slots (31) arranged in base piece (1) (See Figure 4), although it is more logical to think of the reverse construction.
- The knuckle of this spacial structure is completed with a strength member (7), which may be a tubular section one of whose ends abuts against the inside of poles (11) and (22).
- A stud (71) is provided inside said tube (7), whose head (23) abuts against pole (22), and by means of nut (4), it abuts under pressure against pole (11), thus helping to secure base pieces (1) and (2) against one another.
- Figure 5 shows a single-piece element (16) in revolution (16) which is weld (15) attached to tubular section (6).
- Said single-piece element (16) possesses a conical frustrum side surface in order for it to suit different diameters of tube (6).
- The tightening screw (20) possesses a head (8) which, either directly or by means of a widened area (9) or an additional member such as a washer having the same shape, is offered to the inside surface of base piece (1), (2). The contact face of the widened area (9) is spherical so as to facilitate contact.
- The single-piece element (16) possesses a face (10) which is offered to the outside face of the same base piece (1), (2), and said contact face is spherical as well for the reasons given.
- Screw (20) and single-piece element (16) are threaded together in engagement, thus accomplishing the joint between tubular section (6) and base piece (1), (2).
- The desig can also be such that the side surface (14') adjacent to the joining face (10) is shaped as a conical frustrum, thus preventing said contact face (10) from needing to be excessively large.
- It is to be noted that the joining means comprised (a) of the strength member (8) with its stud (71) and fittings, and (b) of screw (5) in the engagement area, can be used either individually or together, and the presence of protrusions (30) is always optional.
