Description

BACKGROUND OF THE INVENTION

The present invention relates to an improved side frame for a loading plane of tables and chairs and particularly a side frame capable of assembling and fastening loading members to support loading of human body and goods.

Many known leisured chairs now available on the market have loading planes (seat pads or backrests) made of metal tubes or wooden beams coupling with fabrics or leather. During fabrication, the fabrics or leather are cut to the sizes of desired loading planes. The cut fabrics and leather are stitched on the rims to form coupling sections. Then metal tubes or wooden beams of selected sizes and lengths are disposed into the coupling sections to form loading planes for supporting people and goods. There are some other types which have stitched binding rims formed on the fabrics or leather. Then a plurality of apertures are formed on the binding rims to engage with spring hooks which are in turn fastened to metal tubes or wooden beams.

The leisured chairs set forth above require a lot of processes and time in production and assembly. They are also difficult to fabricate. After using for a period of time, the stitching of the fabrics or leather could be frayed or ruptured, or the springs connecting the fabrics (or leather) and metal tubes or wooden beams could have material fatigue, or the metal tubes or wooden beams will result in deformation. All this could cause undesirable using conditions or even hazards.

In order to remedy aforesaid problems, there are other loading planes for leisured tables and chairs being developed and introduced. One of the examples is to form a frame made of metal tubes (or bars) to support the loading plane, then fasten a plurality of loading elements (plate forms) made of metal or wood to the frame. While such a construction is stronger and more durable for supporting human weight or goods, it takes more work and time to produce and assemble. Moreover, after assembly of the products is finished, a lot of screws will be exposed. It is not sightly and is easy to injure users. The fastenings between the loading elements and frame could get loose after using for a period of time, and could cause injury to users. Moreover, the fastenings must be done by means of tools in a fixed and tight manner. It is not convenient for users to use.

SUMMARY OF THE INVENTION

The primary object of the invention is to resolve the foregoing disadvantages. The invention aims to provide an assembly type frame to couple with loading members for use in tables and chairs.

Another object of the invention is to provide an assembly type frame to couple with loading members for assembling loading planes of tables and chairs with least possible processes and time.

A further object of the invention is to provide a loading plane that has no exposed screws or fasteners after assembled to enhance total appealing of the finished products and avoid hurting users.

To attain the foregoing objects, the frame of the invention includes a loading section which has one end extended to form an extended section which in turn connects an eave section. The eave section and the loading section form an anchor section therebetween, and also have respectively a chamfer section corresponding to each other. The loading section and chamfer section have respectively an aperture formed thereon to receive a fastener for fastening a last loading member to prevent other loading members from loosening. After the fastener is engaged and fastened, the aperture may be covered by a cap to prevent the fastener from rusting and also to mask the fasteners from exposing outside to make the appearance of the finished products more sightly after assembly. The loading plane thus formed may be adapted for use in tables and chairs to support people and goods.

The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1, the side frame for loading planes of tables and chairs of the invention consists of a [0016] frame 1 and a separator 2 located in the frame 1. Loading members (not shown in the drawing) may be disposed in the frame 1 and spaced by the separator 2 to form a loading plane to support people or goods.
The [0017] frame 1 may be made of, but not limited to, wood, metal (such as steel, aluminum) or plastics. The frame 1 includes a loading section 11 which has one end extended to form an extended section 12 which in turn connects an eave section 13. The eave section 13 and the loading section 11 form an anchor section 14 therebetween, and have respectively a chamfer section 15 and 16 opposing to each other. The loading section 11 and the chamfer section 16 have respectively an aperture 111 and 161 formed thereon corresponding to each other.
The [0018] separator 2 is made of, but not limited to, wood, metal (such as steel, aluminum), plastics or rubber. The separator 2 is disposed in the anchor section 14, and has a dividing section 21 which has two free ends formed respectively an indented recess 22 to engage with a loading member (not shown in the drawing), and two jutting edges 23 and 23′ formed on the upper side and lower side of the dividing section 21 slidable in the chamfer sections 15 and 16.
Referring to FIG. 2, when to assemble the [0019] frame 1 of the invention, dispose the separator 2 into the frame 1 by wedging the jutting edges 23 and 23′ into the chamfer sections 15 and 16, and slide the separator 2 into the anchor section 14 of the frame 1. The dividing section 21 may seal the slot opening of the anchor section 14 to make the assembled products having more attractive appearances.
Referring to FIGS. 3 and 4, when in use, loading members [0020] 4 (such as wood, metal, plastics) may be assembled on the frame 1 by disposing in sequence the separators 2 or loading members 4 alternately in the anchor section 14 of the frame 1, and use the indented recesses 22 and 22′ at the free ends of the dividing section 21 to engage with the end surface of the loading members 4 such that the loading members 4 will be assembled and fastened to the frame 1 in a spaced fashion.
When assembling the [0021] frame 1 and loading members 4, the separator 2 may be dispensed with so that the loading members 4 will contact one another closely in the frame 1 to form another type of loading plane.
In addition, the bottom sides of the [0022] loading section 11 and chamfer section 16 may have respectively an aperture 111 and 161 formed thereon corresponding to each other. A fastener 6 may be allowed to pass through the aperture 111 and 161 to fasten the last loading member 4 for preventing other loading members 4 from loosening. After the fastener 6 is engaged, the aperture 111 may be sealed and covered by a cap 7 to prevent the fastener 6 from rusting, and also to mask the fastener 6 from exposing outside. The appearances of the finished products will be more sightly and have more appealing.
Moreover, after the [0023] frame 1 and loading members 4 are assembled and fastened, the edges of the frame 1 may be coupled with a bordering member 8. The bordering member 8 has a first plug element 81 and a second plug element 82 to wedge into the anchor section 14 and loading section 11 to smooth the edge rim of the frame 1. The edge rim thus formed is less likely to hurt people and can further enhance the total appearance and appealing of the finished products.
Referring to FIG. 5 for an embodiment of the invention, the [0024] loading member 4 has an aperture 41 engaged with a positioning element 3. The positioning element 3 is made of, but not limited to, wood, metal (such as steel, aluminum), plastics or rubber. When the loading member 4 is assembled in the anchor section 14, the positioning element 3 may couple closely with the chamfer sections 15 and 16 to prevent the loading member 4 from loosening or sliding in the frame 1 to allow the loading member 4 be fastened firmly to the frame 1.
Referring to FIG. 6 for another embodiment of the invention, the [0025] loading members 4 are assembled in the frame 1 and spaced by the separators 2 to form a loading plane 5 for a chair (or table) to support the weights of people or goods.
Furthermore, the [0026] frame 1, separator 2 and loading member 4 may be made according to selected specifications and dimensions so that assembly can be done quickly to save processes and time.
