Description

The invention relates to stationery and can be used to create universal ballpoint pens.

A ballpoint pen is known comprising a tubular body with a nose sleeve, means for fixing the writing rods in length, means for fixing the tip of the writing rods, and a cap with a pocket holder bracket, the housing and the nose sleeve being made with end holes for the tip of the writing rods. The well-known handle allows the use of at least 4 types of rods - long and short with a thin body, thickened (high capacity) and rods of type B 1C handles.

A disadvantage of the known fountain pen is its complexity and low manufacturability.

The aim of the invention is to simplify the design of the handle, increasing its manufacturability and ease of use.

This is achieved by the fact that, in the known pen, the means for fixing the writing rods along the length consists of a tube with an internal jumper with a hole for air passage located at a given distance, and the means for fixing the tip of the writing rods consists of a stepped fixing sleeve with an axial hole, and the sleeve made with the possibility of installation and removal in one of the holes in the housing or the end hole of the sleeve.

In the case of a pen case, the housing is made in the form of a cup for holding several spare rods and other pen accessories, the means for fixing the tip of the writing rods consists of two stepped fixing bushings with axial holes of different diameters.

Figure 1-4 shows the types of handles using, respectively, a long and short shaft, a thickened shaft and a shaft of a handle of type B1C; Figures 5-8 show a pen version of a handle with similar rods; figure 9 - tube with an internal jumper; Fig. 10-12 - modification of the handles.

The handle consists of a cylindrical body 1, a nose sleeve 2, fixing bushings 3, 4, a tube 5 with an internal jumper and a cap 6 with a pocket holder bracket.

In a single-rod version, the diameter of the end hole of the housing 1 corresponds to the diameter of the cylindrical part of the tip of the handle shaft of a type B1C 7. In the housing 1 there is a hole of the same diameter on the side, the diameter of the axial hole of the sleeve 3 corresponds to the diameter of the tip of the thickened rod 8.

The sleeve 3 thus contains a rim-stop, its outer diameter corresponds to

the diameter of the cylindrical part of the rod 7, and the inner diameter of the tip of the thin rods 9, 10. The inner diameter of the nose sleeve 2 is larger than the diameter of the rods 9, 10. but less than the diameter of the wide

rod parts 8.

The nasal sleeve 2 can be made with an internal channel for mounting a thickened rod 8. The housing 1 (see FIG. 11) can be made with an internal channel for installing a thickened rod 8.

In the variant of the pen-case (see Fig. 5-8)

the inner diameter of the housing 1 is increased, he

looks like a glass, and the handle itself contains

tubular holder 11, external dimensions

bushings 3 and 4 are the same, but the diameter of the axial hole of the sleeve 4 corresponds to the diameter of the tip of the rod 8, and the diameter of the channel of the holder 11 is larger than the diameter of the rods 9, 10, but smaller than the diameter of the wide part

rod 8. The nasal sleeve 12 has a conical shape with the same hole in the front part as that of the sleeve 2. The tubular holder 11 and the sleeve 3 can be combined into a single insert 13.

in both cases, the housing 1 contains

the internal thread, and the nose shells 2, 12 - the external thread corresponding to the internal thread of the housing 1. The tube 5 is made with an offset jumper containing

a breathing hole, the inner diameter of this tube being larger than the diameter of the casing of the rods 9, 10, and the outer being smaller than the diameter of the channel of the nasal sleeve 2. The parameters of the jumper of the tube 5 are selected so

which ensures the fixation of the rods 8-10 in the housing 1 (see Fig. 1-8), for which the ratios should be satisfied:

45

l L - And + a. b L - h a.

where L is the length of the internal cavity of the handle (see Fig. 1,5).

a; b, l - parameters of the tube 5 (see Fig. 9);

Ii; l2 - lengths of the bodies of the rods 8-10. The depth a of the short channel of the tube 5 is selected from the condition of the rods not falling out 8-10. The value of L can be chosen from the design and operating conditions, for example, from the condition of the rods and other accessories being placed in the housing 1 (see Figs. 5-8). to use a long rod 9 (see Fig. 1), a sleeve 3 is placed in the end hole of the housing 1, into the channel of which the tip of the rod 9 is inserted. On the other hand, the tube 5 is put on the short side of its channel, after which the sleeve 2 and the housing 1 screwed per unit Noah whole. The rod 10 is likewise installed, but with the difference that the tube 5 is put on the opposite side (see FIG. 2). To use the thickened rod 8, its tip is inserted into the hole of the sleeve 2, the tube 5 is put on the shank of the rod 8, as well as on the rod 10, after which the housing 1 and the sleeve 2 are screwed (see Fig. 3). For use with the rod 7, the sleeve 3 is inserted into the side opening of the housing 1. which is screwed onto the sleeve 2, after which the rod is inserted outside the end hole of the housing 1 (see Fig. 4). Similarly, the handle is assembled for other modifications (see Fig. 10.11).

In the embodiment of the pen case in the housing 1 there are spare rods 7-10 and / or bushings 3.4. When using the rod 9, a sleeve 3 is inserted into the hole of the sleeve 12, the tip of the rod 9 is inserted into it, and the tube 5 is put on the tube 5 with the long part of its channel. A sleeve 4 is placed in the housing 1, after which it is screwed onto the sleeve 12 (see Fig. 5). Rod 10 is installed in the same way, but with that

the difference is that tube 5 is worn on the opposite side (see FIG. 6). To use the rod 8, instead of the sleeve 3, a sleeve 4 is installed in the sleeve 12. A holder 11 is put on the tip of the rod 8, after which it is inserted with the front part into the hole of the sleeve 4. A tube 5 is put on its shank. Sleeve 3 is placed in the housing 1, and the sleeve 12 and housing 1 are screwed up. When using the rod 7, it is inserted externally into the sleeve 12 (see Fig. 8).

The use of a pen-case in another modification (see Fig. 12) provides for the use of a single insert 13 instead of a sleeve 3 and a holder 11.

When using the proposed handle, the convenience of its operation is increased, the design is simplified, which includes only 4-6 parts, which are very simple to manufacture. For the single-rod version, the overall dimensions are reduced, and for the pen-case variant, it becomes possible to store several spare rods in the case, which is indispensable when used in remote areas by geologists, tourists, etc. The pen is also very convenient for schoolchildren and students.
