Description
The present invention is relevant with a kind of folding joint, and it is shaped as the contraposition part of two longitudinal extensions, and each contraposition part all has a wall, and the xsect of wall generally is a groove semicircle, that outer envelope has several longitudinal extensions, the xsect undulate of these grooves.The semicircle outer envelope of two contraposition parts is meshed with groove each other, and connects together with a web member, and two clamping elements are from the mutual substantially parallel stretching, extension outwardly in the end of this wall, and the flat extension of formation lunette.Therefore, the shape of the xsect of each contraposition part is generally U-shaped.
When big picture or the interim wall structure that uses are installed, the separation wall of the exhibition material of Temporary Display or office for example.Known this wall structure can be installed in the prefabricated framework, and this framework clamps the marginal portion of wall structure.With the leg that is installed in the framework lower edge frame vertical straight is fixed, framework has usually constituted the separation wall that shower is put on display in the exhibition, and upright framework close installation mutually delimited the use zone of shower.But these frameworks are easy to move to unsuitable position after being collided, and this has moved with regard to meaning the regional boundary line of delimiting for shower, gives a kind of amorphous impression of people.Known framework can interfix with various securing members, and to obtain continuous wall element, this wall element comprises several interconnective frameworks.
In order to realize the effective connection between the different frames, people know: can be fixed on a plurality of special connecting pieces the marginal portion of framework, these frame edge are relative with another edge of next framework.The connection surface of web member has the groove of several longitudinal extensions, forms several teeth between the groove.But this connected mode is often damaged easily, because the fixed strain difficulty relatively effectively mutually between the web member.For this reason, need some special-purpose fasteners on the framework for web member is fixed to, for example screw connects reinforcement, thereby has improved the cost of product and made installation difficulty more.
The purpose of this invention is to provide a kind of connector, this connector can be eliminated the shortcoming of prior art, provides reliable connection between two elements of folding joint.
Above-mentioned purpose realizes by a device, wherein each contraposition part has a V-arrangement abutment wall that is provided with at an angle at least between clamping element, the lunette that connects clamping element is pointed at the tip of V-arrangement abutment wall, in the clamping element the inside, be provided with the centre of gyration of each contraposition part at the top of the V-arrangement wall that is provided with at an angle apart from a certain distance of lunette, form a bearing pin, web member is housed on this axle is used for connecting contraposition part, in contraposition part, the centre of gyration constitutes the center of curvature of lunette.
Below in conjunction with embodiment and with reference to corresponding accompanying drawing this device is described in detail.Fig. 1 is the figure of above-mentioned folding joint; Fig. 2 is the perspective part-view of folding joint; Fig. 3 is mounted in two folding joints on the framework.
Below in conjunction with embodiment this folding joint is illustrated.In this embodiment, framework is used to install big picture, and this folding joint also has other purposes certainly.As shown in Figure 1, folding joint comprises the gabarit part 1,2 of two identical longitudinal extensions.Therefore, only one of them gabarit part is described below.It is the semicircular arcwall part 3 that goes up that gabarit part 2 has a cross section, and several teeth 4 are arranged on the envelope outside it, and these teeth 4 are along the longitudinal direction of this gabarit part, and normally envelope upper surface 3 extends outside whole, and forms profile of tooth.The half-round curve of arcwall part 3 ends at each end of clamping element 5,6, the arcwall part stretches out from this end and becomes mutual opposed parallel walls part, these parallel walls are preferably extended along the whole length of arcwall part, and the straight portion of the round wire of composition arcwall, therefore, the shape of this gabarit part xsect generally takes the shape of the letter U.The part of the wall of clamping element slightly is spill, makes the free end at clamping element, and the distance between this wall part is maximum.Each clamping element 5,6 ends to projecting inward flange respect to one another 7,8, and flange 7,8 parts with respect to the clamping element wall are generally the right angle.These flanges preferably extend to the whole length of clamping element.
Two relative supporting members 12,13 are in the tie point of abutment wall 9,10 inboard from clamping element, stretch with the direction that generally meets at right angles of the part with the wall of clamping element, so the free end of supporting member 12,13 in flange free-ended above stretching, extension.
Shown in Fig. 2,3, gabarit part 2 is having the place of a segment distance that a slit 15 is arranged from its free end, and the longitudinal direction of this slit and gabarit part is perpendicular and extend to whole arcwall part.Therefore, slit ends at the place a little less than corresponding clamping element 5,6.In the place that is directly adjacent to slit 15, in abutment wall 9,10 by a certain angle of intersection and be lower than cylindrical hole 11 1 segment distance places and be provided with second slit (not shown).Like this, just formed a side direct puncture from clamping element 7 cross the gabarit part to the opposite side of clamping element 8 and with the perpendicular slit of its longitudinal direction.
As shown in Figure 2, folding joint comprises two gabarit parts, and gabarit part 1 links to each other with another gabarit part 2.These two gabarit parts are disposed opposite to each other by means of the outer envelope of arcwall part 3, and the flank profil of gabarit part is engaged with each other.The gabarit part must firmly connect each other, so that first tooth 16 of the first gabarit part 1 can place the space 17 between first and second teeth of gabarit part 2, so that form effective engagement of tooth between the flank profil of each gabarit part.
Shown in Fig. 2,3, each free end of framework moulded parts 23 has T shape boss 24, and boss is used to contact and be installed between the clamping element 5,6 of certain distance, and clip together with flange 7,8 with clamping element the end that is preferably in the gabarit part.As Fig. 3 saw, folding joint has constituted the outer separatrix of framework with framework moulded parts 23, can place picture 25 in the framework, and the marginal portion of picture 25 is between clamping element 5,6, and have the support that rests on the supporting member 12,13, as shown in Figure 1.
When gabarit part 1,2 is coupled together, they contact with each other in the 4 intermeshing modes of the tooth on the outer wall 3.And first tooth 16 that makes the first gabarit part 1 is a particular importance over against the front in the space between first and second teeth of the second gabarit part 2, the profile of tooth gabarit can all keep in touch on whole contact semicircle like this, the first gabarit part 1 just can roll relatively along the flank profil of the second gabarit part, about 180 ° of the relative second gabarit part change in location, promptly with it fully relatively.Then web member 20 is inserted in the slit 15 of gabarit part, hole 11 fronts of corresponding hole 21 on the abutment wall on the gabarit part of correspondence 9,10 are aligned substantially.Because the distance that the hole is 21 is less than the distance in 11 in the hole on the relative gabarit part 1,2, the pass that hole 11 and hole are 21 will have some dislocation, and the center of each in the hole 21 will slightly be ahead of the center in hole 11 like this.For with web member with the mutual tensioning of gabarit part, tension pin 22 be inserted in each hole 11 and each hole 21, and this tension pin tip should be able to easily be inserted into by corresponding aperture and not have tangible resistance.Because the slightly larger in diameter of tension pin in the diameter in above-mentioned hole 11 and hole 21, need apply when tension pin is passed hole 11 with power to overcome the friction force between tension pin and this hole.This can pour hole 21 with certain hand tool with this tension pin at an easy rate and finish.Because the distance that the hole is 21 is less than the centre distance in hole 11, two gabarit parts with regard to mutual extrusion together.The center in hole 11 will be done one's utmost adjacent to each other, thereby change the centre distance in hole 21, and clamping element 5,6 will be done one's utmost adjacent to each otherly under the towing of abutment wall like this, and the distance of 7,8 of flanges shortens as a result.
Because hole 11 is arranged on the circumference central authorities of wall part, and each gabarit part is that web member by thereon 11 extensions in hole movably links together, on the whole field of conjugate action, and can substantially evenly tensioning between the flank profil of these gabarit parts.
When picture 25 is installed, its is inserted flange 7,8 until contact supporting member 12,13, just be embedded between the flange 7,8 of clamping element 5,6 with the T shape boss 24 of afterframe moulded parts 23.Because clamping element will be done one's utmost closely when pouring tension pin 22, clamping element will encase reliably together with their corresponding flanges 7,8 and the T shape boss 24 of clamping frames moulded parts, and hold them at certain ad-hoc location.Because clamping element has concave side walls, will produce elastic reaction, clamping element is clamped boss all the time securely in certain deviation range of boss 24 like this.Even also can being inside jagged spill by clamping element sidewall spill with clamping element sidewall xsect under state of nature easily, this pre-clamping obtains.A kind of simple clamping element clamping means realize with the tractive abutment wall, because this can increase the concavity of clamping element side.Therefore, do not need any fastener just the T shape boss 24 of framework moulded parts 23 can be fastened on the gabarit part.
The present invention promptly is not subjected to above-mentioned explanation not to be subjected to the restriction of embodiment shown in the drawings yet, but can change within the scope of the following claims.The web member that for example connects two gabarit parts can be added in the free end of two gabarit parts, and not in the hole in the gabarit part.Even it is contemplated that and divide two in work with framework moulded parts part and T shape projection section, thereby T shape boss can be clamped between the clamping element medial surface with aforesaid way, and the framework moulded parts can be fixed on certain type fastener on the T shape boss.This fastener can be made of the cone tank in this T shape boss outshot, and this outshot inserts in the framework moulded parts, and the center of this cone tank produces some displacements with the hole in relative this framework moulded parts like this.A screw passes this hole, and is rotated a contacts side surfaces that makes it with this cone tank, and like this, do one's utmost to be consistent with the center in this hole in the center of this cone tank, and this boss is just to this framework moulded parts motion as a result.
