Abstract

The present invention is to install a pillow on all the chairs that can lean back back to the head and neck to be stable stably to move the pillow by chain in the back of the chair, so that the pillow moves up and down from the back of the chair To use the pillow in the desired position on the backrest.

Description

Chair pillow and move equipment {Chair pillow and move equipment}

The present invention relates to a pillow moving device and a pillow for providing a comfortable rest by installing pillows on the backs of all chairs with the backrests moving backwards, but there are several types of pillow moving devices. It is easy to install and the effect is a perfect moving device to provide a pillow for the chair.

Until now, the back of the chair has a fixed headrest and is bent, so that it cannot be properly adjusted according to the height of the person, and in most cases it is difficult to stabilize the neck. So, there are many ways to install a pillow, but among them, there is a folding method or a stepped gear moving method, but the configuration is very complicated and the effect is very insufficient.

The present invention is a method of moving a pillow using a chain as a main method of the moving device, by moving and stopping the chair pillow with a mobile device consisting of a complete and simple.

The headrest of the backrest is cut into the backrest to make an incision 11, and through the incision, a fixing shaft 9 for fixing the pillow 1 is fixed to the chain 7 inside the backrest, and the chain Some of the gears (7) are engaged with the gear (8), the gear is turned into a gear (10) by turning the handle (5), the gear is rotated, the chain engaged with the gear moves, the pillow can move, convenient for power-free manual If you automate with power, it becomes a very convenient moving device.

In other words, the device using the chain has the same structure as the gear device of the bicycle, so there is no breakdown or error even after long-term use. The configuration is simple (the chain is usually mass-produced and it is very easy to produce), and the incision 11 of the backrest is very narrow, and if the incision of the backrest is wide, a part of the body can reach the mechanism behind the pillow and the like. Even when the chain device is installed on a chair, it is simple to attach the assembled device (chain case and) to the back of the chair in a suitable and firm area, and the pillow moves very smoothly. It is flexible and is designed to be better than ever.

The present invention is a pillow for the head and neck of the person sitting on the chair, more specifically, the neck support. It is a device for constructing a chair pillow that securely supports a person's neck in the chair back and uses the pillow in a desired position.

The present invention is to provide and reduce the pillow for the chair as a simple, complete, solid, flexible and effective device by using the chain of the pillow moving device

FIG. 1 is a front perspective view of a chair in which the center backrest 6 of the chair is slightly lower than the backrest 2 of the chair so that it is curved so that the head is stabilized in the seat. It is a perspective view where the pillow 1 is located.

FIG. 2 is a cross-sectional view of the chair from the upper center of the back of the chair (below the cut portion of the CD of FIG. 1) to the chain case 4 (7) (detailed in FIG. 4) is coupled to the rectangular circle (4 and 7 is a sectional view in which the gear 8 is arranged and the fixed shaft 9 connected to the chain 7 is connected to the pillow.

A is a lower part of the back portion (6)

Figure B is to project the pillow in the original configuration of the same configuration or backrest.

FIG. 3 is a cross-sectional view taken along the line A-B of FIG. 1 and connected to the pillow 1 by a fixed shaft 9 in the chain case 4, that is, a cross-sectional view seen from the back of the backrest;

Figure A is intended to have the same effect even if the pillow does not protrude above the backrest surface and may be stable at the lower backrest. Figure B is a cross-sectional view of the pillow projecting over the original condition.

4 is an overall perspective view of the chain case 4, in the center of the front surface of the chain case 4, there is a gap 12 through which the fixed shaft 9 and the fixed shaft move, and the chain 7 is in the chain case 4. In the direction of the dotted line arrow to the left and right. Turning the knob 5 is a perspective view of the chain case 4 which is configured to rotate the connected gear shaft 10 and the gear 8 to bite and rotate the chain (not shown in this figure and see FIG. 5).

After assembling and inserting all parts of the chain case (4), cut into 2 pieces in length. When fully engaged, the mobile unit is complete with this diagram.

FIG. 5 is a cross-sectional view of the central portion of FIG. 4 (dotted line Da in FIG. 4), which is covered by the chain case 4. FIG.

The chain (7) is coupled to the chaincase (4). The upper chain (7) and the lower chain (7) are integrally connected by the ends of each other (see Fig. 4), and firmly and completely secure the fixing shaft (9) at the position in the chain to connect with the pillow.

The pillow 1 is connected to the fixed shaft

The gear (8) for moving the chain (7) is installed to rotate by the gear shaft (10), and the gear (8a) engaged with the chain is coupled to the chain (7), so that when the gear (8) moves, the chain Move

When turning the knob (5) connected to the gear shaft (9) back and forth

The gear 8 rotates back and forth and the chain connected to the gear is able to reciprocate up and down and the pillow moves as the chain moves.

The rotation of the gear of the present invention is manually moved by the handle, but if the electrical connection is smooth, it is better to drive by the electric device.

In order to fix the pillow in the desired position, it is necessary to push and pull the handle with a locking device on the gear shaft, and the chain case 7 may be fixed to a rigid part inside the chair back.

(8) The gear shaft 10 is positioned at the right and left centers of the chain case, but the upper and lower positions may be installed where appropriate.

As you rest against the chair, the pillow is positioned from the base of your head to the neck (the head doesn't need to be raised), so your head and head aren't tilted from side to side to relax. It is to adjust the position of the pillow, and it is a moving device of the pillow using the chain. If the chain is not used until now, the configuration is simple, there is no trouble, the production cost is reduced, and the operation pillow is very flexible. Will. Until now, there is no smooth moving device, so there is little supply of chair pillows.
