Abstract

The present invention is a kind of pen suitable for person lying on his back to write continuously and its usage. The pen features its thickened neck with one ink storing cavity outside the ink channel between the nib and the neck, and has one capillary pipe with one end inserted in the ink storing cavity and the other end inserted into the ink channel; one ink bag with one end connected to the neck via a switching valve and the other end connected via a by pass to a piston cylinder; and one dead weight pressurizing piston inside the piston cylinder with one opened end communicated to the ink supply pipe to the ink storing cavity. When the pen is used in writing with upwards nib, ink is fed to the nib by means of capillary action for continuous writing. The pen is especially suitable for patient in bed to write.

Description

Continuous writing pen for lying on one's back and using method thereof

Affiliated field

The present invention relates to a kind of pen and using method thereof, relate in particular to pen and using method thereof that a kind of suitable writing continuously in supination is used.

Background technology

For the handicapped people of limbs or patient inconvenience, need bed to face upward sometimes and write because of health; At some in particular cases, in addition the normal person also have the situation of writing of need lying on the back and take place.But the common pen of writing all is to finish water supply process by the deadweight of ink.When writing when facing upward, ink gravity does not have effect, can only write several capable words, and can't realize continuous writing.Even this has brought inconvenience sorry to them.

Summary of the invention

In order to satisfy the writing continuously in supination specific demand, care about people with a disability and other laid-up people's life, the invention discloses pen and using method thereof that a kind of suitable writing continuously in supination is used.

Technical solution of the present invention is achieved in that

A kind of continuous writing pen for lying on one's back, comprise the cap for brush, nib, pen item and handwriting, it is characterized in that the diameter overstriking of described pen item, thereby the periphery of the water channel that links to each other with nib at pen item position forms a water storage cavity, one end of capillary channel inserts water storage cavity, and the other end inserts on the above-mentioned water channel; One end of the ink cartridge in the described handwriting links to each other with the pen item by a transfer valve, and the other end then is connected with piston cylinder by shunt valve; The sealing of piston cylinder one end, the other end is connected with the feed pipe of connecting in pen item water storage cavity; There is the deadweight pressurizing piston inside of piston cylinder.

Described deadweight pressurizing piston adopts the bigger material of proportion to make, as the bigger metal material lead of proportion etc.So the pressure of piston pressurization is from the gravity of itself, and need not manpower or other machinery pressurizations.

Described piston cylinder is divided into and is connected as a single entity but different two sections of internal diameter, and the blind end internal diameter is bigger, and the deadweight pressurizing piston is arranged in the bigger section of a pipe of internal diameter and forms matched in clearance with the piston cylinder inwall.So that ink flows through from the gap and the resistance when making piston fast reposition or reducing pressurization.

The using method of described continuous writing pen for lying on one's back is characterized in that comprising to pen and pours water, lie on the back write the operation and sitting write operation; Concrete grammar is as follows:

When a) pouring water, pull out transfer valve, pinch ink cartridge, insert in the ink bottle, loose one's grip, can in ink cartridge, shunt valve and piston cylinder, pour into ink;

B) lie on the back when writing, nib up or oblique upper pushes transfer valve, and the deadweight pressurizing piston is pressed into the ink in the piston cylinder in the water storage cavity through feed pipe because of the gravity effect moves down, and promptly finishes the retaining of once pressurizeing; Ink in the water storage cavity is supplied with nib by capillary channel, realizes facing upward the continuous writing process; After the ink in the water storage cavity used up, with nib towards the end sky a little while, again with nib up, the retaining of pressurizeing once more got final product;

When c) sitting was write, nib is the below down or tiltedly, and transfer valve is pulled out, and the ink in the ink cartridge is directly supplied with nib through transfer valve, finishes sitting continuous writing process.

Compared with prior art, the advantage of continuous writing pen for lying on one's back of the present invention is conspicuous: it can be converted by common pen, nib structure is not changed, the fundamental characteristics and the basic training that have kept common pen are used, characteristics that it is maximum and advantage be and can carry out continuous writing by back floating position, the demand of writing in the time of can satisfying people that physical disabilities are arranged and patient especially and lie in bed.Structure of the present invention and use principle can also be applied to the roof drawing simultaneously, and wall is drawn or the like.Labor and material saving, convenient and practical and easy operating have wide and market prospects.

Description of drawings

1 in accompanying drawing of the present invention, promptly

Fig. 1 is the structural representation that the present invention plucks the cap for brush.

Among the figure, 1, nib 2, pen 3, transfer valve 4, ink cartridge 5, deadweight pressurizing piston 6, shunt valve 7, piston cylinder 8, feed pipe 9, water storage cavity 10, capillary channel.

The specific embodiment

Now in conjunction with the accompanying drawings the present invention is done further and specify.

As shown in Figure 1, continuous writing pen for lying on one's back of the present invention is to be converted by common pen, nib 1 structure is changed, the cap for brush then needs correspondingly to have increased its internal diameter with the overstriking of 2 diameter of beginning to write, the diameter overstriking at pen 2 position, periphery at the water channel that links to each other with nib 1 forms a water storage cavity 9, when writing when lying on the back, nib 1 up or oblique upper, transfer valve 3 is pushed, the deadweight pressurizing piston 5 that adopts metallic lead to make is pressed into the ink in the piston cylinder 7 in the water storage cavity 9 through water supply hose 8 because of the gravity effect moves down, and promptly finishes the retaining of once pressurizeing; Then the memory space of ink is by the capacity of ordinary steel pen and ink water pocket 0.8ml, only is increased to that the ink storage quantity of water storage cavity 9 just reaches about 2ml, but also can design more jumbo water storage cavity; By capillarity, ink in the water storage cavity 9 is supplied with nib endlessly along capillary channel 10, the groove width of capillary channel * be about deeply 0.3 * 0.3mm, so the capacity of water storage cavity 9 just can be supplied the quantity of ink that one-time continuous is write, after the ink in the water storage cavity uses up, only need towards the end sky a little while, more up nib with nib, relend and help the deadweight of piston 5 to pressurize, the ink in the piston cylinder 7 is pressed into by water supply hose 8 has once more promptly finished retaining once more in the water storage cavity 9; By a transfer valve 3, making it is that nib is up or during oblique upper in the continuous writing demand main suitable lying on the back, still the basic function that has a common pen realizes that promptly sitting writes, downwards or the oblique normal ways of writing of below of nib just, at this moment only need transfer valve 3 is pulled out, ink in the ink cartridge 4 is directly supplied with nib 1 through transfer valve 3, promptly finishes sitting continuous writing process.
