Definitions
- the invention relates to a handwriting or application device according to the preamble of claim 1.
- the known handwriting or application device has one relatively large overall length, since the bladder forming the chamber in the axial direction of the housing between the valve device and must be arranged at the rear end of the writing tip. About that furthermore, because of this arrangement, there is a risk that the with Bladder filled with writing fluid due to violent movements of the Device performs lateral deflection movements, so that it becomes a corresponding shift of the contact arm of the circuit for the valve device come and this circuit is closed can be. Then there is a short opening Valve device, although the chamber is filled, and as a result, in addition to the static pressure Writing fluid in the chamber the total static pressure of the Writing liquid in the storage room at the rear end of the writing tip on.
- a handwriting or application device is used to solve this task according to the preamble of claim 1 according to the invention designed such that the interior of the bladder only with the Ambient air is connected.
- This connection between Interior of the bladder and ambient air is preferably through a channel formed from the flexible material of the bladder consists.
- the interior of the chamber for writing fluid is not like in the known device, through the interior of the bladder flexible, inelastic material, but the interior the intended bubble is connected to the ambient air and forms only part of the outer wall of the chamber for Writing fluid.
- the bubble for example to the side of the lower section of the pantry in the housing be arranged so that the chamber with a portion to the side of the front of the pantry and with a other section in the area of the rear end of the writing tip located.
- the interior of the bladder is not more filled with writing fluid and thus their weight is low is, the risk of violent movements is also significantly reduced the handwriting or application device to a the valve device pushing the bladder.
- a wall area of the bladder can be placed on one lever arm arranged inside the chamber for actuating the Valve device act.
- This can be an arm of one L-shaped, two-armed lever act on the spring force acts in the closing direction of the valve device.
- the spring force regulates the fluid pressure at the nib and can set according to the capillary behavior of the writing tip become.
- the handwriting or application device shown has a holder-shaped housing 1, in the front end of which Inserted unit from insert 3 and chamber part 5 and is attached, for example by gluing.
- the chamber part 5 is approximately L-shaped on average and forms together with the insert element 3 most of the wall of the chamber for free Writing fluid that has an area 6 and an area 7 having.
- In the insert element 3 is the center from the front Writing tip, in the present case a porous writing wick 4, used, the rear end in connection with the area 6 the chamber stands for free writing fluid.
- Area 7 of Chamber extends from area 6 in the axis-parallel Leg of the chamber part 5 to the rear.
- the rear wall of area 6 of the chamber forming wall of the Chamber part 5 is a pipe socket 16, which is to the rear this wall protrudes.
- This protruding section of the pipe socket 16 penetrates the wall, as indicated in Figure 2 a free writing fluid consisting of a tubular film containing storage space 2.
- the outside of the tubular film stands in through a ventilation opening provided in the housing Connection with the ambient air, however, is opposite this sealed.
- the other forms of storage rooms shown in DE-PS 43 13 180 as well as a pantry is suitable, which is at the rear a labyrinth seal forming the seal against liquid leakage having.
- the front end of the pipe socket 16 becomes, as in FIG. 3 shown, sealed by a valve plate 15, which sits on an arm 13 of a two-armed lever, which in the Chamber 6, 7 arranged and pivotable about an axis 14.
- This lever is operated by a spring 17 at the free end of its attacks other arms 12, towards the closed position of the Valve device loaded, i.e. the spring 17 normally presses the valve plate 15 sealing against the lower end of the Pipe socket 16.
- a bubble 8 made of flexible, non-elastic Material whose interior 9 via a channel 10 and a Ventilation opening 11 communicates with the ambient air.
- the channel 10 is forward by continuing the bubble material formed, and the outer surface of the wall of the channel 10 is in front area with a through opening in the insert element 3 glued so that this passage opening on the one hand opposite the chamber 6, 7 sealed and on the other hand with the ambient air connected is.
- the bubble 8 is located between the Outer wall of the chamber part 5 and the outside of the arm 12 of the two-armed lever, and for the rest it is of the writing fluid surrounded in chamber 6, 7.
- the chamber 6, 7 is in a sufficiently filled State, the pipe socket 16 is sealed and the Bladder 8 essentially "compressed". That state is shown in Figure 3.
