Abstract

The utility model discloses a pair of chopsticks, which can be operated easily, and is suitable for patients lack of fingers and children. The utility model can be operated with only one thumb pushing the button, the pose of holding the push-button chopsticks is greatly similar to the pose of holding traditional chopsticks when the push-button chopsticks are in use, and harmonious atmosphere can be kept. The utility model is composed of a pair of chopsticks, a gap bridge mechanism and a button. The gap bridge mechanism comprises a supporter, a bell crank lever and '__' supporters. The chopsticks are clamped between the '__' supporters, and can rotate around each mandrel. The '__' supporters are clamped at the parallel space of the supporters of the gap bridge mechanism, and a pair of rollers of the '__' supporters is positioned in the arced drop pit of the two chopsticks. When the button is pushed downwards, the bell crank lever is rotated, and through transmission, the chopsticks are pushed off. When the button is loosened, the chopsticks are clamped.

Description

Push-button chopsticks

The present invention relates to a kind of new-type chopsticks.It is a kind of tableware that is used for Chinese meal, can be for finger deformity and the patient who trembles, and children and some can not use the westerner of chopsticks to use.

Existing chopsticks do not have the chopsticks of contact to form by two independently, mutually.During operation, need four finger Coordinating Activities, finish complicated action, this can feel difficulty to those above-mentioned people.If use the clamp dishware, with regard to Chinese meal, lose grace, influence harmonious atmosphere, also cause the uneasiness of user's psychology.

Purpose of the present invention is exactly that children and some can not use the westerner of chopsticks that a kind of chopsticks easy and simple to handle are provided to the disabled patient who reaches of finger.Only need a thumb just to press and to operate; In addition, during use, hold the very similar of chopsticks posture and position and ordinary people,, eliminate user's uneasy psychology to such an extent as to be difficult to distinguish from the philtrum of having meal together.

The present invention finishes as follows.It is crossed bridge mechanism and button and is formed by two chopsticks.

Two chopsticks followed bridge mechanism to be hinged by mandrel separately, crossed the support of bridge mechanism, were the fixed heads that is parallel to each other by two, and heart position forms with the spacer connection therein.

In the parallel space in the gap bridge mechanism rack, there is one

The shape support, its two parallel planes are parallel with the former two planes two, two, and the two can do relative slip.One pair roller is arranged on it.Two chopsticks are clipped in In the parallel space between the shape support, can rotate around mandrel separately.When not working, two rollers lay respectively in the arc pit of two chopsticks.The mandrel of chopsticks passes

The shape support is fixed on the fixed head.

The right angle rocking arm can rotate around bearing pin, and its free arm is positioned at the outside of fixed head (crossing bridge mechanism), and button is positioned at its end; The other end, pass fixed head and

The square hole of shape support is followed

Shape support side contacts.

Under the effect of reed elastic force, button takeoffs, though the chopsticks clamped condition, when pressing the button, rocking arm rotates, the other end

Moving The shape support slides, and two rollers just run off the pit on the chopsticks, and chopsticks are strutted.

With reference to the accompanying drawings embodiments of the invention are elaborated below.Fig. 1 is a front view, and Fig. 2 is a vertical view, and Fig. 3 is the A-A cutaway view, and Fig. 4 is the B-B cutaway view.

This device crosses bridge mechanism 2 by two chopsticks 1 and button 3 is formed.Cross bridge mechanism and be positioned at the position that people grip usually on the chopsticks, its support is formed by spacer 5 connections by two fixed heads parallel to each other 9.The mandrel 12 of two chopsticks 1 by separately and mistake bridge mechanism 2 be commissure mutually.And can rotate around mandrel.Mandrel is vertical with fixed head 9, and the plane of two chopsticks formation is parallel with fixed head 9.

Two chopsticks profile symmetries, length is 170～260 millimeters.Chopsticks have the bearing of a projection on the second half section, and convex symmetry is inwardly pressed dress.Bearing hole matches with mandrel 12.Distance between these two mandrels 12 is simulated when the normal person holds chopsticks, and the distance of two chopsticks centers of rotation has recessed arc hole near the chopsticks bearing.

Shape support 8 is arranged in the parallel space of gap bridge mechanism rack inside, and the former two parallel planes are parallel with two fixed heads 9 two, two respectively, and can do to slide relatively.Its available 0.3～0.4 millimeter brass book plate (routine H62) is made, and at opening part two aluminum spacer axles 7 is arranged, and is symmetrical by dress, is equipped with on it and adopts the Miniature ball bearing among two roller 6(embodiment, the outer 7 * φ interior 3 * b3.5) of appearance and size φ.

On two parallel planes of shape support 8 square hole is arranged all, can allow mandrel 12 therefrom pass through, and be fixed on the fixed head 9.

When chopsticks are not worked, Two rollers 6 on the shape support 8 just in time are arranged in the arc pit of two chopsticks.

There are bearing and parallel its surperficial bearing pin 14 of a pair of projection in the outside of a fixed head 9 therein.

Have a right angle rocking arm 13 to rotate around bearing pin 14, an end of rocking arm passes the square hole on the fixed head 9, enters

In the shape support 8, calcaneus branches frame side offsets.The other end is a free end, and it crosses the bridge mechanism outside, and there is button 3 at the end end, and when rocking arm rotated very small angles, the stroke of button was very short, can regard as with fixed head vertical.

Chopsticks 1 are followed mandrel 12,

Assembly relation between shape support 8 and the gap bridge mechanism rack is; Two chopsticks are sandwiched in

Also can rotate in the middle of the shape support 8 around mandrel 12;

The shape support is sandwiched in the gap bridge mechanism rack and can slides relatively; Two mandrels 12 pass

The shape support is the square hole on two faces up and down.Two ends are fixed on the gap bridge mechanism rack; Two rollers 6 on the shape support 8 just in time are arranged in the arc pit of two chopsticks.

Between the free arm of right angle rocking arm 13 and fixed head 9, dihedral reed 11 is arranged; Between two chopsticks of crossing the bridge mechanism rear, arc pornographic movie 4 is arranged, under their effect, when not touching the button, button takeoffs, and two chopsticks are clamped condition.

Pressed the button 3 o'clock, right angle rocking arm 13 rotates, and the lower end volume of rocking arm is moving

Shape support 8 relative gap bridge mechanism racks slide, and two rollers 6 run off the arc pit on the chopsticks.Because the distance between roller is fixed, the result struts two chopsticks.

Advantage of the present invention, be exactly that operation is very simple, just can replace four of the sort of needs of past to point the compound action that cooperation just can be finished with a simple button actions, and above-mentioned improvement is again to finish under the prerequisite that keeps traditional tableware (chopsticks) use characteristic.
