Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loupe for enlarging a fine shape of a symmetrical object or a small character, for example. About possible loupe.

[0002]

2. Description of the Related Art As one of typical conventional loupes, a handle 5 is mounted on a frame 52 for holding a lens (convex lens) 51 as shown in FIG.
There is a loupe with a handle provided with 3. When using the loupe with the handle, the position of the loupe (lens 51) is adjusted so that the observation object (not shown) and the lens 51 have an appropriate positional relationship by holding the handle 53 in a hand. Thereby, it becomes possible to view the observation target object at a magnification suitable for the performance of the lens 51.

Therefore, when using the loupe with the handle, the handle 53 is usually held with one hand, so that it cannot be used when it is necessary to work with both hands. There is a point.

As a loupe capable of working with both hands while enlarging and observing an object to be observed, as shown in FIG. 13, a lens (convex lens) 61 is used.
There is a stand loupe in which one end (lower end) is attached to the other end of an arm 64 fixed to a stand 63 via a frame 62. In this stand loupe, the position of the lens 61 is adjusted by deforming the arm 64 so that the observation object (not shown) and the lens 61 have an appropriate positional relationship. It is possible to work with both hands while viewing at an appropriate magnification.

However, in the case of the stand loupe, it is necessary to place the stand on a desk, a table, or the like, so that the stand loupe cannot be used without a table, a table, or the like. is there. In addition, even when placed on a desk or table, there is a need for a space for placing the stand on the upper surface of the desk or table, so that use of the stand may be restricted.

The present invention has been made to solve the above problems, and provides a loupe which can be operated with both hands while observing an object to be observed through a lens without requiring a mounting table such as a desk or a table. The purpose is to do.

[0007]

In order to achieve the above object, a flexible loupe according to the present invention comprises a lens,
It is formed by fitting and connecting a plurality of resin elements so that their positional relationship can be changed with each other, and the lens is attached to one end side, and the shape can be freely changed. And a mounting means attached to the other end of the flexible arm for detachably mounting the flexible arm to a predetermined mounting target.

Further, in the flexible loupe of the present invention, the flexible arm has a pin portion (male portion) having a substantially spherical main portion and a cylindrical socket portion (female type portion) having a substantially spherical inner main surface. ) Is formed by connecting a plurality of resin elements having at least one of them formed by slidably fitting a pin portion and a cylindrical socket portion thereof.

As described above, the flexible loupe of the present invention comprises a lens, a resin-made flexible arm whose shape can be freely changed, and a lens which can be detachably attached to a predetermined mounting object via the flexible arm. Mounting means for mounting, for example, on an umbrella of a desk lamp, on a shelf, at the end of a book, etc., and deform the flexible arm to hold the lens in a predetermined position. This makes it possible to use the device easily without using a desk or table, and to work with both hands while viewing the object to be observed through the lens.

[0010] In the flexible loupe of the present invention, "a plurality of resin elements are fitted and connected so that their positional relationship can be changed with each other."
For example, one element constituting a flexible arm includes a pin portion (male portion) having a substantially spherical main portion and a cylindrical socket portion (female portion) having a substantially spherical inner peripheral surface. The pin portion of one element is slidably (rotatably) fitted into the cylindrical socket portion of another adjacent element, and this connection mode is repeated to connect a plurality of elements. Is a concept meaning a connection mode in which the shape of the entire arm can be freely changed. In the pin portion, a groove parallel to the axial direction (for example, a cross-shaped groove or a single-character groove) is formed from the distal end side to the base end side, or a cut is formed in the cylindrical socket portion. By adjusting the fitting state, the deformation and the shape stability can be easily adjusted.

As described above, when a flexible arm is used in which a plurality of resin elements are fitted and connected so that the positional relationship between them can be changed, a conventional thin metal plate is formed into a spiral shape. Compared to the case where a wound metal flexible arm is used, the overall weight can be reduced and the stability of shape retention can be improved. In addition, as a material forming the element, various resins such as a so-called engineering plastic such as a polyacetal resin, a polyamide resin, and a polycarbonate resin, a vinyl chloride resin, and a polypropylene resin can be used.

In the flexible loupe of the present invention, the term “lens” means the lens itself when the lens is directly attached to the flexible arm, but when the lens is held by the frame, This is a broad concept including a combination of a lens and a frame. Further, in the flexible loupe of the present invention, there is no particular restriction on the type of lens, and it is possible to adopt a configuration using various lenses such as a convex lens, a concave lens, and a polarizing lens. The term “mounting means” is a concept that means a clip-type or screw-type mounting jig using a spring, and various known means can be used.

Further, the flexible loupe of the present invention is characterized in that the lens is made of resin. "The lens is made of resin" means not only the case where the lens itself is made of resin but also the case where only the lens or both the lens and the frame are made of resin when the lens is held by the frame. It is a concept that includes. Various resins such as an optical acrylic resin, a polycarbonate resin, and a styrene resin can be used as the resin forming the lens. When the lens is made of resin, the overall weight can be further reduced to improve portability and usability, and the burden on the flexible arm is reduced, simplifying the structure of the flexible arm and reducing costs. Reduction can be achieved.

Further, the flexible loupe of the present invention is characterized in that a light for illuminating an object to be observed is provided at or near the lens. The light can illuminate the observation target, making it possible to see the observation target even at night or in a dark place, reducing the restrictions on the use environment such as location restrictions and brightness, and further improving usability. Can be improved.

Further, in the flexible loupe of the present invention, by providing a through hole in each element constituting the flexible arm, a void portion penetrating at least a main portion of the flexible arm in a longitudinal direction is formed, and At least a main part of a lead wire for connecting the power supply is housed in the gap.
By forming a gap in the flexible arm, it is possible to store the lead wire that connects the light and the power supply in the flexible arm, and the connection reliability is reduced due to the lead wire being exposed to the outside. It is possible to prevent the drop. In addition, there is no special restriction | limiting in the shape of the said through-hole and space | gap part, Various shapes are possible.

Further, the flexible loupe of the present invention is characterized in that an azimuth magnetic needle is provided at or near the lens. In the case where the compass is provided with a compass or a magnetic needle near the lens, for example, when the loupe is attached to an atlas by an attaching means and the map is viewed, the map is checked or the distance is checked while confirming the direction. And convenience can be further improved.
