Description
- 1. Field of the Invention
- The present invention relates to a chair backrest with ventilating function and, more particularly, to a chair backrest that provides improved safety and an aesthetically pleasing appearance.
- 2. Description of the Related Art
- Chairs are a necessity in daily life and there are a wide variety of chairs that provides improved sitting comfort and air-ventilating function. FIGS. 4 and 5 of the drawings illustrate a conventional chair backrest for providing a ventilating function. The backrest includes a rigid hollow
rectangular frame 1′ and a net 2′. Thenet 2′ is made of soft material and wraps the outer peripheral edge of theframe 1′ tightly to hereby embrace theframe 1′ and to thereby support a user when the user lies on the backrest with thenet 2′ providing a ventilating function. - The conventional backrest includes several drawbacks. First of all, the
frame 1′ might be deformed or even broken and thus injure the user when the lying force from the user is relatively large, as the user is only supported by theframe 1′ that is located in thenet 2′. Second, the shape of the backrest is confined to the shape of theframe 1′, which is relatively monotonous. Further, theframe 1′ is still visible via the openings or holes in thenet 2′, which adversely affects the aesthetically pleasing appearance. - An object of the present invention is to provide a chair backrest for providing improved safety and an aesthetically pleasing appearance.
- A chair backrest in accordance with the present invention comprises an inner frame, a net, and an outer frame. The inner frame is a hollow member and has an outer peripheral edge. The net is made of soft material and embraces the outer edge of the inner frame. The outer frame is a hollow member made of rigid material and includes a peripheral groove defined in a side thereof and extending along a periphery defining the outer frame. A bottom wall defining the peripheral groove includes a plurality of fastening holes. The outer peripheral edge of the inner frame and an outer peripheral edge of the net are received in the peripheral groove of the outer frame. Fasteners are respectively extended through the fastening holes and into the inner frame.
- Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
- FIG. 1 is an exploded perspective view of a chair backrest in accordance with the present invention.
- FIG. 2 is a perspective view of the chair backrest in accordance with the present invention.
- FIG. 3 is a sectional view of the chair backrest in accordance with the present invention.
- FIG. 4 is an exploded perspective view of a conventional chair backrest.
- FIG. 5 is a perspective view of the conventional chair backrest.
- Referring to FIGS. 1 through 3, a chair backrest in accordance with the present invention generally includes an
inner frame 1, a net 2, and anouter frame 3. Theinner frame 1 is a hollow member that has a shape corresponding to that of a backrest. Thenet 2 is made of soft material and includes an opening 21 in a lower end thereof and azipper 22 provided to the lower end of thenet 2 for closing theopening 21. Thus, theinner frame 1 can be inserted into thenet 2 when theopening 21 is still open, and thezipper 22 is used to close theopening 21 to make the net 2 embrace an outer peripheral edge of theinner frame 1 tightly. - The
outer frame 3 is a hollow member that is made of rigid material and that includes ahollow interior 33 for ventilation purpose. Theouter frame 3 further includes aperipheral groove 31 defined in a side thereof and extended along a periphery of theouter frame 3. A bottom wall defining theperipheral groove 31 includes a plurality of fasteningholes 32 for engaging withfasteners 34. Thus, as illustrated in FIG. 3, the outer peripheral edge of theinner frame 1 and an outer peripheral edge of thenet 2 are inserted into theperipheral groove 31 andfasteners 34 are extended through thefastening holes 32 in theperipheral groove 31 and into theinner frame 1, thereby securing theinner frame 1 in theperipheral groove 31. Thus, theouter frame 3 provides the whole backrest with an increased strength and improved safety for reliably supporting the user. In addition, theinner frame 1 is hidden in theouter frame 3, thereby providing an aesthetically pleasing effect. - According to the above description, it is appreciated that the chair backrest in accordance with the present invention provides improved safety and aesthetically pleasing effect in addition to the original ventilating function.
- Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention as hereinafter claimed.
