1. Field of the Invention
The present invention relates to a chair and, more particularly, to a chair having elastic cords.
2. Description of the Related Art
A conventional chair 50 in accordance with the prior art shown in
In accordance with the present invention, there is provided a chair, comprising at least one support frame having two opposite side rails, a plurality of connectors mounted in each of the two side rails of the support frame, and a plurality of elastic cords each mounted between the two side rails of the support frame and each having two opposite ends each attached to a respective one of the connectors. Each of the two side rails of the support frame has a hollow inside provided with a slideway to allow insertion of each of the connectors. Each of the two side rails of the support frame has a side provided with a guide slot connected to the slideway to allow insertion of each of the connectors and to guide movement of each of the connectors. The guide slot of each of the two side rails of the support frame has a width smaller than that of the slideway.
The primary objective of the present invention is to provide a chair having an outstanding outer appearance.
Another objective of the present invention is to provide a chair that is operated safely.
A further objective of the present invention is to provide a chair, wherein each of the connectors is fully hidden in the slideway and the guide slot of each of the two side rails of the support frame so that each of the connectors will not be exposed outwardly from the support frame to enhance the outer appearance and safety of the chair.
A further objective of the present invention is to provide a chair, wherein the guide slot of each of the two side rails of the support frame has a width smaller than that of the slideway so that each of the connectors is received in the slideway of each of the two side rails of the support frame and limited in the guide slot of each of the two side rails of the support frame to prevent each of the connectors from being detached from each of the two side rails of the support frame.
A further objective of the present invention is to provide a chair, wherein each of the connectors is provided with two opposite fixing ribs each secured in the retaining groove of each of the two side rails of the support frame, so that each of the connectors is positioned in each of the two side rails of the support frame exactly and stably.
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.
Referring to the drawings and initially to
Each of the two side rails 24 of the support frame 20 has a hollow inside provided with a slideway 25 to allow insertion of each of the connectors 30. Each of the two side rails 24 of the support frame 20 has a substantially U-shaped cross-sectional profile. Each of the two side rails 24 of the support frame 20 has a side provided with a guide slot 21 connected to the slideway 25 to allow insertion of each of the connectors 30 and to guide movement of each of the connectors 30. The guide slot 21 of each of the two side rails 24 of the support frame 20 has a width smaller than that of the slideway 25 and has two opposite sides each provided with a retaining groove 22 connected to the slideway 25. Each of the two side rails 24 of the support frame 20 has two opposite distal ends each provided with a bent limit flange 26 to define the retaining groove 22. The limit flange 26 of each of the two side rails 24 of the support frame 20 extends inwardly toward the slideway 25.
Each of the connectors 30 is slidably inserted into the slideway 25 of each of the two side rails 24 of the support frame 20 and limited in the guide slot 21 of each of the two side rails 24 of the support frame 20. Each of the connectors 30 is fully hidden in the slideway 25 and the guide slot 21 of each of the two side rails 24 of the support frame 20. Each of the connectors 30 has a block shape and is provided with two opposite fixing ribs 33 each secured in the retaining groove 22 of each of the two side rails 24 of the support frame 20. Each of the two fixing ribs 33 of each of the connectors 30 is provided with a fixing recess 39 for mounting the limit flange 26 of each of the two side rails 24 of the support frame 20. Each of the connectors 30 has an inner wall having a first end provided with at least one entrance 32 to allow passage of a respective one of the elastic cords 40 and to limit one of the two opposite ends 42 of the respective elastic cord 40 and a second end provided with at least one receiving chamber 31 connected to the entrance 32 to receive the one of the two opposite ends 42 of the respective elastic cord 40. The receiving chamber 31 of each of the connectors 30 is connected between the slideway 25 and the entrance 32 and has a width greater than that of the entrance 32.
In assembly, each of the two opposite ends 42 of each of the elastic cords 40 is attached to a respective one of the connectors 30. Then, each of the connectors 30 is inserted into the slideway 25 of each of the two side rails 24 of the support frame 20 and limited in the guide slot 21 of each of the two side rails 24 of the support frame 20 so that each of the elastic cords 40 is mounted between the two side rails 24 of the support frame 20 by the connectors 30.
Accordingly, each of the connectors 30 is fully hidden in the slideway 25 and the guide slot 21 of each of the two side rails 24 of the support frame 20 so that each of the connectors 30 will not be exposed outwardly from the support frame 20 to enhance the outer appearance and safety of the chair. In addition, the guide slot 21 of each of the two side rails 24 of the support frame 20 has a width smaller than that of the slideway 25 so that each of the connectors 30 is received in the slideway 25 of each of the two side rails 24 of the support frame 20 and limited in the guide slot 21 of each of the two side rails 24 of the support frame 20 to prevent each of the connectors 30 from being detached from each of the two side rails 24 of the support frame 20. Further, each of the connectors 30 is provided with two opposite fixing ribs 33 each secured in the retaining groove 22 of each of the two side rails 24 of the support frame 20, so that each of the connectors 30 is positioned in each of the two side rails 24 of the support frame 20 exactly and stably.
