Description
- 1. Field of the Invention
- The present invention relates to a joint, and more particularly to a joint having a protrusion rod for furniture combination.
- 2. Description of Related Art
- Conventional furniture is assembled by immovable joints between parts which is easily damaged during transportation or moving and occupies huge space, therefore, the transportation cost is correspondingly increased. Currently, assembled furniture is published to the market and enables to be disassembled into parts for packing. By transporting the assembled furniture in pieces, the occupied space and transportation cost are significantly reduced and damage caused by bumping during transportation is also avoided. The assembled furniture is mostly detachably combined by means of screws and nuts or screws and metal hinges. The adoption of such means has drawbacks such as that the parts of furniture shall be drilled to make holes at connection places. The holes are getting to be enlarged or deformed after reassembling the parts several times and thus the furniture has poor stability and is easily damaged to the parts. Moreover, gaps of the conventional assembled furniture are large which make the appearance not neat.
- The conventional joint has a male buckle and a female buckle, wherein the male buckle has a Z-shaped protrusion rod engaged with a base. The base has an insertion part formed at one end surface integrally and the insertion part has expansion slots. The interior of the insertion part abutting to the base has a recess. The protrusion rod is movably mounted on the base and has its upper surface flush with an upper end surface of the base. A lower end of the protrusion rod is received inside the recess of the insertion part and is movable in a limited range. The female buckle is a cylinder with a receiving hole and has stops formed inside the receiving hole. When insertion part of the male buckle inserts into the receiving hole of the female buckle, the protrusion rod locates in position. Although the foregoing structure makes the parts of the furniture assemble, the assembled furniture is easily deformed or even break apart when users load weight or pressure on the furniture and the protrusion rod disengages from the receiving hole. Stability and safety of the disassembled furniture with the conventional joints are insufficient.
- A main objective of the present invention is to provide a joint with protrusion rod for furniture which is stable and has enhanced combination efficiency.
- To achieve the foregoing objective, the joint with protrusion rod comprises:
- a male buckle and a female buckle engaged with each other, wherein the male buckle has a hollow insertion stub with multiple expansion slots and has a receiving hole; and
- a protrusion rod movable received inside the receiving hole of the male buckle and having a locking plate mounted the protrusion rod and multiple fins correspondingly aligned with and operationally engaged with the expansion slots when the protrusion rod is wedged into the insertion stub.
- Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

The male buckle has a hollow insertion stub with multiple expansion slots and has a receiving hole to movably receive a protrusion rod. A distal end of the protrusion rod is movably engaged with the insertion stub. The protrusion rod has a locking plate and multiple fins correspondingly engaged with the expansion slots when the protrusion rod is wedged into the insertion stub. By having the above structure, difficulty of disengagement of the protrusion rod from the insertion stub is significantly increased to prevent the disengagement to of the male buckle and the female buckle and thus the joint has increased combination strength and is excellent in utility.
- As shown in
FIGS. 1 to 8 , a preferred embodiment of a joint with a protrusion rod in accordance with the present invention comprises amale buckle 1 and afemale buckle 2 engaged with each other. Themale buckle 1 has ahollow insertion stub 3 withmultiple expansion slots 4 and has a receiving hole (not numbered) to movably receive aprotrusion rod 5. A distal end of theprotrusion rod 5 is movably engaged to theinsertion stub 3. Theprotrusion rod 5 has alocking plate 6 mounted thereon andmultiple fins 7 correspondingly aligned with theexpansion slots 4. When theprotrusion rod 5 is wedged into theinsertion stub 3, themultiple fins 7 are engaged with theexpansion slots 4 respectively. - Before assembling the parts of the furniture for delivery from factory, a horizontal board part has a first adopting hole at end and the
male buckle 1 is wedged into the first adopting hole. A vertical supporting part has a second adopting hole at side and thefemale buckle 2 is secured into the second adopting hole. When the parts are assembled, the end of the horizontal board part is placed close to the horizontal supporting part to insert theinsertion stub 3 into thefemale buckle 2. Then, thelocking plate 6 is pushed to make the distal end of theprotrusion rod 5 to insert into theinsertion stub 3 and to expand theinsertion stub 3. Meanwhile, thefins 7 of theprotrusion rod 5 insert into theexpansion slots 4 respectively to enhance the security of combination of theprotrusion rod 5 and theinsertion stub 3. Therefore, difficulty of disengagement of theprotrusion rod 5 from theinsertion stub 3 is significantly to increased to prevent the disengagement of themale buckle 1 and thefemale buckle 2 and thus the joint has increased combination strength and is excellent in utility. - In the embodiment of this invention, the number of the
expansion slots 4 is two and the number of thefins 7 is same as the one of theexpansion slots 4. Theexpansion slots 4 are evenly defined around theinsertion stub 3. In preferred embodiment of the present invention, the number of theexpansion slots 4 and thefins 7 are four, or selectively two, three or five. When the distal end of theprotrusion rod 5 is pushed toward and into theinsertion stub 3, theinsertion stub 3 is expanded to avoid theinsertion stub 3 disengaging from thefemale buckle 2. - The
male buckle 1 in the preferred embodiment has a recess for accommodating thelocking plate 6. The recess is a dovetail-shaped recess 8 so that thelocking plate 6 is protected from breaking when thelocking plate 6 is driven and tilted. Lifespan of thelocking plate 6 is increased. - In the preferred embodiment of the present invention, a front surface of the
locking plate 6 is spaced from the front end of themale buckle 1 with a gap when theprotrusion rod 5 is accommodated in the receiving hole of themale buckle 1 and the distal end of theprotrusion rod 5 is wedged into the insertion stub 3 (as shown inFIG. 7 ). When theprotrusion rod 5 is pushed backward into the receiving hole of themale buckle 1, a flat screwdriver is inserted into the gap to push thelocking plate 6 to drive theprotrusion rod 5 backward to the receiving hole. - In the preferred embodiment of the present invention, a rear end of the
locking plate 6 extends out of the recess when theprotrusion rod 5 is pushed ii backward to the receiving hole. When the lockingplate 6 is pushed to make theprotrusion rod 5 wedged into theinsertion stub 3, the rear end of thelocking plate 6 is pushed inward without obstruction of sidewall of themale buckle 1 so that assembly of the joint is easy and quick and has excellent utility. - In the preferred embodiment of the present invention, the locking
plate 6 has multipleanti-slip grooves 10 which facilitate the pushing of thelocking plate 6 when the friction between theprotrusion rod 5 and theinsertion stub 3 is small. - As shown in
FIG. 3 , in the preferred embodiment of the present invention, themale buckle 1 is composed of two semi-bodies. One of the semi-body has atenon 11 and the other semi-body has acorresponding mortise 12 to make thetenon 11 engaged with themortise 12. When themale buckle 1 is assembled, theprotrusion rod 5 is placed in the receiving hole of one semi-body, and then the other semi-body is driven to close to make thetenon 11 wedged into themortise 12, thereby, themale buckle 1 is quick assembled. - Moreover, the
male buckle 1 and thefemale buckle 2 have multiple annular stops defined on outer periphery. Therefore, themale buckle 1 and thefemale buckle 2 have strong combination with the parts of the furniture when wedged into the first adopting hole and the second adopting hole to increase excellent stability of the joint in combination with the parts of the furniture. - The periphery of the
