Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to binoculars, and more particularly to binoculars having an outer shape that is similar to an aluminum can of beer or the like, which is a well-known form.

[0002]

[Prior art]

 The outer shape of industrial products is often determined by their functions, but on the other hand, there are many products that have been devised in design. The design of such industrial products is generally decorative, and has a side that depends on the sensitivity of the designer. On the other hand, there are also industrial products in which known forms are used as they are. Since such a product has an external shape that is not very similar, the user can enjoy not only the function of the product but also the unexpectedness of the appearance.

[0003]

[Problems to be solved by the device]

 In the case of products that pursue such unexpectedness in appearance, it is difficult to select what kind of well-known form should be adopted for what kind of industrial product at the product development stage. In other words, if the function of the industrial product can be sacrificed, there is no particular problem, but it is first of all that the outer shape of the product is kept as it is without losing the original function of the product. However, it is difficult to select an appropriate combination from the myriad of industrial products and well-known forms. Further, even if a particular well-known form is selected, there is a difficulty in developing the original function of the product without impairing the form.

An object of the present invention is to provide binoculars which have the same outer shape as an aluminum can, such as a well-known can of beer, without impairing the function of the binoculars.

[0005]

[Means for Solving the Problems]

 In order to achieve the above technical problems, in the aluminum can-shaped binoculars of the present invention, a cylindrical main body, an upper cap fitted to the upper end of the main body, and a lower end of the main body are fitted. The lower cap forms the same outer shape as an aluminum can such as canned beer, and the main body can be divided into left and right half-split members and these left and right half-split members can be spread to the left and right. In the left and right half members, an opening provided with an eyepiece lens is formed in one of the upper and lower walls, and an opening provided with an objective lens in the other wall. Is adopted.

Even the aluminum can-shaped binoculars of the present invention preferably have a focusing mechanism like general binoculars. In order to reduce the number of parts, it is desirable to use the hinge shaft as the rotary shaft of the operation dial that constitutes a part of the focusing mechanism.
