Abstract
“A headrest for an office chair includes a headrest body, two connecting blocks, a support frame and a hook. The support frame has two L-shaped hooks in an intermediate portion, and the headrest can be assembled with a backrest of an office chair by a hook and L-shaped hooks of the support frame to enable the headrest being assembled with any office chair easily. Moreover, the headrest body can be adjusted in its height and angle to be usable by users of different physical heights.”
Description
- 1. Field of the Invention
- This invention relates to a headrest for an office chair, particularly to one easily adjustable in its angle and height, and conveniently assembled and disassembled.
- 2. Description of the Prior Art
- A conventional headrest of an office chair is generally made stationary, impossible to be assembled with any office chairs or to be adjusted in its angle and height, so users of different physical height cannot sit comfortably, obliged to change its sitting posture to conform to the height of the headrest. Therefore, users may suffer from a sour head and back owing to a long period of use.
- This invention is to offer a headrest for an office chair, easily adjustable in its angle and height, and simple to be assembled on and disassembled from an office chair.
- The features of the invention are a headrest body, plural connecting blocks, a support frame and a hook. The headrest body is wrapped around by a soft material, provided with two shafts connected to the support frame. The connecting blocks are hollow columns connected to the shaft of the headrest body, provided with a projecting block with a through hole for a fastener to fit through to connect to the support frame. The support frame is Y-shaped, having a ball with a slot respectively at two upper ends, with the projecting block of the connecting block to fit therein, and hooks extending from an intermediate portion to hook on a backrest of an office chair to hang the headrest body on the office chair. The hook is L-shaped, fixed in a recess of the support frame by fasteners.
- Then the shafts enable the headrest to be adjusted in its height, and the support frame can let the headrest adjusted in its angle.
- This invention will be better understood by referring to the accompanying drawings, wherein:
-
FIG. 1 is a perspective view of a headrest for an office chair in the present invention; -
FIG. 2 is an exploded perspective view of the headrest for an office chair in the present invention; -
FIG. 3 is a side view of the headrest of the office chair in the present invention, showing the headrest being adjusted in its height; -
FIG. 4 is a side view of the headrest of the office chair being adjusted in its angle in the present invention; and, -
FIG. 5 is a side view of the headrest of the office chair in the present invention. - A preferred embodiment of a headrest for an office chair in the present invention, as shown in
FIGS. 1 and 2 , includes aheadrest body 1, two connectingblocks 2, asupport frame 3 andplural hooks 4 as main components. - The
headrest body 1 is wrapped around by a layer of soft material and provided with twoshafts 11. - The connecting
block 2 is a hollow column connected with theheadrest body 1 by means of theshafts 11, having aprojecting block 20 extending rearward from the hollow column, and theprojecting block 20 has a throughhole 200 for afastener 5 to screw theprojecting block 20 with thesupport frame 3. - The
support frame 3 is nearly shaped as Y, having a ball formed at an outer end of two side rod portions and aslot 30 formed in the ball for theprojecting block 20 to fit in and secured stably by thefastener 5 engaging with a threadedhole 31 formed in the ball and a nut fitted in anut recess 32 of the threadedhole 1. Further, thesupport frame 3 is provided with an L-shaped hook 33 respectively extending from an intermediate portion of the two side rod portions for hooking with a backrest of an office chair, and arecess 34 formed in a lower portion with a threadedhole 340 in an upper wall of therecess 34. - The
hook 4 is shaped nearly as L, having twocurved portions 41 and a threadedhole 410 in a rear portion for thefastener 5 to engage with to fix thehook 4 on the recess of thesupport frame 3. - In assembling, as shown in
FIGS. 2 and 3 , thesupport frame 3 with thehook 4 together can easily be combined tightly on a backrest of an office chair, by means of the twohooks 33 of thesupport frame 3 and thehook 4 hooking stably with the backrest and fastening tightly with thefasteners 5 fixing thehook 4 so the headrest in the invention may be assembled or disassembled from an office chair. Moreover, the backrest of an office chair needs no special components for combining the headrest. - Next, in order to adjust the height of the headrest, referring to
FIG. 3 , thebody 1 is moved up and down by theshafts 11 moving up and down in the throughholes 21 of the connectingblocks 2. - In order to adjust the angle of the headrest, referring to
FIG. 4 , push the body to swing up or down with thefastener 5 located in the throughhole 30 of thesupport rods 3 loosened a little and functioning as a pivot, and then screwing tight thefastener 5 after the angle is adjusted as wanted. - Thus, a user can adjust the angle and the height of the headrest to suit to the user's height to get a comfortable sitting position.
- While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
