Embodiments of the prefabricated telescope of the present invention will be described below with reference to the accompanying drawings.

〔Example〕

In FIG. 1 and FIG. 2, reference numeral 11 is the main lens barrel;
Reference numeral 12 indicates a sub-lens barrel containing an objective lens, and numeral 13 indicates a sub-lens barrel having an eyepiece.

The main lens barrel 11 is made of an empty can of a beverage such as juice or beer, and both end faces are open.

These cans have standardized dimensions, and generally have an inner diameter of 52.3 m and a length of 104.3 m or 132 m.
It is 8n.

The sub-lens barrel 12 includes a main body made of a synthetic resin molding and an objective lens. The main body is made of flexible synthetic resin such as polypropylene resin, and has an outer cylinder 15 having a shallow cylindrical shape.

The outer cylinder has an inner diameter that is approximately equal to or slightly smaller than the outer diameter of the empty can 11. An inner tube 16 is disposed coaxially inside the outer tube and supported by an end wall 17 of the outer tube. The objective lens 18 is housed in the inner tube and fixed by the elasticity of the synthetic resin forming the sub-lens barrel. For this,
The inner diameter of the inner tube is made slightly smaller than the outer diameter of the objective lens 18, and by pushing the lens 18 into the inner tube 16, the lens 18 is positioned by a presser foot 19 formed integrally with the inner tube. , is held by the elastic deformation of the inner cylinder 16. The inner tube has a tapered hole 20 at its end, so that the lens 18 can be smoothly inserted into the hole of the inner tube. In addition, when fixing the objective lens, in the case of other resins, the diameter of the hole in the inner cylinder 16 should be made slightly thicker than the lens 18 (
This may also be achieved by fitting and bonding the lens holder 20Δ to the inner tube 16 as shown by the chain line.

The sub-lens barrel 13 has a main body made of the same synthetic resin as the sub-lens barrel 12;
It is equipped with an objective lens. This main body also has sub-lens barrel 1.
2 is made of the same synthetic resin as the sub-lens barrel 12, and has a shallow cylindrical shape 21, and an inner barrel 23 that is coaxially arranged inside the outer barrel and supported by an end wall 22 is integrated. It is made of molded material.

This outer cylinder also has an inner diameter that is approximately equal to or slightly smaller than the outer diameter of the empty can. The inner tube extends outward from the outer tube, and the opening 24 is fitted to the extended end. Eyepiece lens 2
5 is accommodated in this opening, and its position is fixed by the end of the outer cylinder and the opening. Although these lenses 18.25 constitute a Dutch or Galilean telescope in the figure, they may also constitute a Kepler complete telescope.
Furthermore, the lens itself may also be made of a bonded lens.

This telescope opens both ends of an empty can 11 that remains after drinking juice or beer, and attaches a secondary lens barrel 12 to both ends of the empty can.
．． By installing 13, it can be assembled. Attachment is performed by expanding and pushing the outer cylinder so that the end of the empty can 11 is located in the gap formed between the inner cylinder and the outer cylinder. The assembled telescope is empty can 11
Since both ends of the can are hidden by the outer cylinder and the inner cylinder, the user is prevented from being injured by the spills generated when opening the empty can.

Further, in this telescope, a hollow-hole sheet 27 is inserted into the empty can 11 forming the lens barrel, thereby reducing internal reflection. This sheet is made of paper or synthetic resin with a black surface, and has a width related to the circumference of the hollow hole of the empty can 11 and a length related to the total length of the empty can 11. To insert the sub-lens barrel 12.13 into the empty can,
1, the sheet 27 is rolled up into a cylindrical shape and inserted into the hollow hole of the empty can 11.

In this case, the sheet 27 is made of paper and is capable of absorbing juice or beer remaining in the empty can.

The telescope of the present invention uses two empty cans, two sets of sub-barrels, and two sets of sheets. In other words, it uses one empty can, another set of sub-barrels, and one sheet. Binoculars can also be obtained by constructing a two-mouth telescope.

In FIG. 3, each telescope is designated as a whole by reference numerals 31 and 32, respectively, and the elements constituting each telescope are distinguished by letters L and R after the reference numerals.

These telescopes 31 and 32 are arranged in parallel so that the eyepieces are spaced apart from each other by a distance corresponding to the distance between human eyes, and are connected to the empty cans 11R and 11 by means of a connector 33.
ILs are interconnected. The coupling itself is made of elastic synthetic resin and, as best shown in FIG. 4, is provided with parallel grooves 34, 35 having a roughly semicircular cross section. These grooves are given a diameter smaller than the outer diameter of the empty cans 11L and IIR, and are arranged so that the distance between the centers of the grooves is related to the distance between the human eyes.

To assemble the binoculars, use the two telescopes 3 as described above.
After creating 1.32, that is, space 11R, II
After attaching the secondary lens barrels 12R, 13L and 12R, 13L to L, empty cans 11R of each telescope.

11L can be fitted into the grooves 34 and 35 in the coupling tool 33 while pushing out the portions forming these grooves.

FIG. 5 shows another configuration of such binoculars. This differs in that the two telescopes are connected by a secondary tube.

It has a structure in which end walls connecting each sub-lens barrel, outer barrel, and inner barrel are combined. The secondary lens barrel on the objective lens side is an empty can 11.
Together with the outer cylinder for R, it is integrally molded with the end wall 117 with the central axis separated by a distance related to the distance between the human eyes. The lens barrel 113 on the eyepiece side also has an end wall 122 connected together, and outer cylinders 121R and 121L, which are attached to the empty cans 11R and ILL, are integrally molded with this end wall 122. . The outer barrels of each sub-lens barrel are connected by a wall 136, as shown in FIG.

The inner tube of each sub-lens barrel is disposed coaxially inside the outer tube, and an objective lens and an eyepiece lens are respectively incorporated therein, as in the previous embodiment. In addition, in the drawing, the inner tube 116L in the secondary lens barrel 112, the objective lens 118L on one side, and the inner tube 123R in the secondary lens barrel 113.
and 123L, and only one eyepiece 125R are shown.

Assembly can be accomplished by inserting the inner anti-reflection sheets 27R and 27L into the two empty cans 11R and IIL, and then attaching the sub-lens barrels 112 and 113 to both ends of the empty cans, respectively, as shown in Figure 3. The assembly can be done more quickly and the number of parts to be carried can be reduced compared to the one shown in FIG.

The embodiment shown in FIG. 7 is a telescope that is divided into two parts, with only the secondary lens barrel on the eyepiece side forming a distance related to the distance between human eyes.

In this case, the sub-lens barrel 213 on the eyepiece side has an outer barrel 221 and an inner barrel 223 at one end, which are similar to those of the previous embodiment. Furthermore, members 241 and 242 are inserted on the opposite side of the sub-lens barrel at a distance corresponding to the distance between human eyes. Although not shown, the eyepiece lenses are built into each of these members 241 and 242, and mirrors, prisms, etc. that guide the light rays incident from the objective lens in the sub-lens barrel 212 to each of the eyepiece lenses are located approximately in the sub-lens barrel 213. It is built into a triangular part. Even with this telescope, after drinking juice or beer,
It can be assembled by inserting the inner anti-reflection sheet 27 into the hollow hole of the empty can 11 and attaching the sub-lens barrels 212 and 213 to both ends of the empty can.

The telescope explained above uses only one empty can, but by using multiple empty cans, it is possible to create a telescope with different magnifications.

The telescope shown in FIG. 8 is a higher magnification version of the telescope shown in FIGS. 1 and 2.

In this telescope, in addition to the empty can 11, another empty can 451 is used, and the ends of each empty can are connected by a connector 452. The lenses of each sub-lens barrel 412, 413 are provided with a lens interval related to the total length when two empty cans 11, 451 are connected, and are assembled into the main barrel constituted by these empty cans. 1 and 2, it is made possible to obtain a telescope of higher magnification when compared to those of FIGS.

As shown in FIG. 9, the coupling tool 452 has a structure in which two inner tubes and two outer tubes in the sub-lens barrel are arranged coaxially. This coupling tool consists of an outer cylinder 453 having an inner diameter slightly smaller than the outer diameter of the empty can 11° 451, a partition wall 454 that divides the outer cylinder into two, and an outer cylinder having an outer diameter smaller than the inner diameter of the empty can. The inner cylinder 455 is arranged coaxially with the
It is made of the same synthetic resin as the secondary lens barrel and is integrally molded.

To connect empty cans, connect the end of one empty can 11 to the outer cylinder 453.
This is done by pushing the ends of the other empty can 51 into the outer cylinder 453. After inserting the sheet 27 into each empty can 11.51, the telescope
1.51 to the non-interconnected ends,
This can be achieved by attaching the sub-lens barrels 412 and 413, respectively.

In such a telescope, by incorporating a correction lens in the coupling tool, it is possible to assemble a telescope with two different magnifications. This allows the objective lens and the eyepiece to obtain a magnification of their own, while also allowing higher magnification to be obtained by adding a correction lens, which is shown in Figure 9. It is incorporated into the inner cylinder 455 of the connector 452 so that different magnifications can be obtained when one empty can or two empty cans are used.

Furthermore, by forming a set using the secondary mirror, connector, etc. shown in these embodiments, the user can be given the freedom to assemble a telescope according to the purpose of use. This cent is, for example, 12 and 13 for the secondary mirror.
, a sheet 27 with a black surface having dimensions related to the inner diameter and length of the empty cans, and a connector for arranging empty cans side by side and integrating them at a distance related to the distance between the human eyes. 33. A second optical system comprising two eyepieces spaced apart by a distance related to the distance between the human eyes and an optical system component for directing the light beam from the objective lens of the objective secondary barrel to each eyepiece. The eyepiece side sub-lens barrel 213, the connector 452 for connecting the ends of the empty cans, and the telescope related to the length of the connected empty cans are sub-units. Since empty juice and beer cans are used for the primary lens barrel, not only can these empty cans, which were previously wasted, be effectively reused, but they can also be used as a backup when watching sports or traveling. By carrying a telescope with you, you can easily create a telescope using empty juice or beer cans.
You can significantly increase your interest in these things,
Furthermore, it is possible to prevent empty cans from being left unattended.
