(a) Field of the Invention
The present invention relates to a joint connector for a combinatorial frame, which can realize extremely firm assembly of combinatorial structures of various forms, including climbing frames, display racks, showcases, and so on.
(b) Description of the Prior Art
Majority of conventional frames are constructed by joining together wooden blocks with rabbet joints. Structural members of diverse direction are assembled by necessarily utilizing different joint connectors, and thus various molds are necessary to provide for the different joint connectors of diverse configuration, which apart from increasing costs, such assembled frames are also relatively unstable. Moreover, models of frames assembled by means of rabbet joints are incondite and of limited diversification.
A primary objective of the present invention is to realize fabricating a frame from a combinatory arrangement of multidirectional joint connectors comprising a main joint connector, a single tube joint connector, a double tube joint connector, connecting blocks, a joint connector box and a screw that enables outwardly continuously extending connectivity in diverse directions therewith, and which provides the frame so assembled with considerable strength, endurance, and rich diversification.
Combinatorial frames, which can be constructed utilizing the present invention, include climbing frames, display racks, and so on.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.
Referring to FIGS. 1 to 5, which show the present invention configured from structural members comprising a main joint connector 1, a single tube joint connector 2, a double tube joint connector 3, a plurality of connecting blocks 4, a joint connector box 5 and a screw 6. The main joint connector 1 assumes a cylindrical form. A base sleeve 11 can couple with a straight tube 7 of a climbing frame (see
One extremity of the single tube joint connector 2 is provided with a sleeve 21, which can couple with the straight tube 7 of the climbing frame. A side of the sleeve 21 is provided with a perforation 22, and a frontal edge is provided with a fan-shaped lug 23. Two triangular grooves 231, 232 are defined in an upper and lower end of the lug 23 respectively (see
The double tube joint connector 3 is provided with two sleeves 31, between which is the connecting piece 311, and which mutually connects the two sleeves 31 therewith. The connecting piece 311 is provided with the perforation 312. A side of each of the sleeves 31 is further separately provided with a perforation 32. An inwardly facing side of the two sleeves 31 assumes form of an arc-shaped piece 33. A plurality of (five) triangular grooves 331 are separately configured in an upper and lower end of the arc-shaped piece 33 respectively. The quads 14 of the main joint connector can thus embed within the grooves 331 of the lower end of the double tube joint connector 3, thereby joining together the main joint connector 1 and the double tube joint connector 3 and fixing position thereof.
The twelve quads 14 atop the main joint connector 1 separately provide for joining together the single tube joint connector 2 and the double tube joint connector 3 by means of rabbeting, and the remaining quads that have not yet been embedded within a groove provide for successively embedding within each triangular groove 41 of each of the single triangular connecting blocks 4, thereby filling and forming a circular cavity provided with 12 triangular grooves 231, 331 and 41 (see
The aforementioned configuration embodies the basic structural members of the present invention, and utilizing the structural members so configured realizes freely combining and assemblage to form connecting directions having two sleeves, eight sleeves, and so on, thus providing the straight tube 7 of the climbing frame to be fabricated in a multitude of directions, including upward/downward, leftward/rightward, frontward/rearward, oppositely diagonal angled directions, and so on, therewith forming a strong and enduring climbing frame assemblage, as depicted in
In conclusion, the present invention realizes fabricating the climbing frame from a combinatory arrangement of multidirectional joint connectors comprising the main joint connector 1, the single tube joint connector 2, the double tube joint connector 3, the plurality of connecting blocks 4, Furthermore, model of the climbing frame so assembled utilizing the present invention can be modified according to inventiveness of a user, and the multidirectional joint connectors ensure the frame is provided with considerable strength and endurance, moreover, is extremely safe.
It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
