Description

  The present invention relates to a magnifying glass. More specifically, the present invention relates to a magnifying glass that can be used as a magnifying glass by a user wearing with both hands or one hand open.

  There are many needs to enlarge a small working part, characters, various displays, etc. at hand when performing fine manual work, reading, or especially operating a smartphone or tablet in recent years. As an example of what meets such needs, there is a reading magnifier stand disclosed in Patent Document 1.

  This reading magnifier stand uses a rectangular lens with a large area and light weight as a magnifier lens, and this magnifier lens can be detachably attached to the lens mounting part, and the magnifier lens can be rotated freely In this way, the adjustment handle is attached to the connection support shaft of the lens mounting part, the arm strut of flexible structure is connected to the connection support shaft, the lower end of the arm support is attached to the stand pedestal, and the wide base plate is attached to the stand pedestal It is.

  In this reading magnifier stand, the distance between the magnifying lens and the desk is increased to make it easier to turn pages and use it for viewing large books such as magazines. However, although this magnifier stand is for reading, for example, when it is intended to enlarge and view a screen of a smartphone that is generally used frequently, the following problems have occurred.

JP 2006-330217 A

  First of all, the reading magnifier stand does not hinder the user from magnifying the object even if the user holds the object with both hands, but the user cannot wear it. Etc. Therefore, the reading magnifier stand is difficult to use in normal use regardless of whether it is indoors or outdoors, for example, and the usability is very bad.

  Further, the reading magnifier stand can be disassembled because the magnifier lens is detachably attached to the lens attachment portion. However, the arm pedestal and the connection support shaft are attached, and the stand base with a larger area of the base plate is heavy and bulky. Therefore, it is usually impossible for the user to think about carrying it. .

  The present invention was devised in view of the above points, and the user can wear it with both hands or one hand open and use it as a magnifying glass. An object of the present invention is to provide a magnifying glass that can be carried in any normal use and is suitable for magnifying a screen.

(1) In order to achieve the above object, the present invention provides a magnifying lens capable of magnifying an object at a required magnification, and a magnifying lens that is provided integrally with the magnifying lens and is deformable and requires no external force A magnifying glass including a strap having a property capable of maintaining a shape.

  The magnifying glass of the present invention has the property that the required shape can be maintained when the strap is deformable and no external force is applied, so that the user does not disturb the work using the hand on the neck or hand. It can be transformed into a mode and attached and put into a worn state. And while the state is maintained, the user can hold the object with his free hand and position the object on the other side of the magnifying lens, so that the user can view the object in an enlarged manner.

  At this time, since the user can freely use both hands, the object held by the hand can be easily located beyond the above-mentioned magnifying lens, and the user is looking at the enlarged view. Even when any operation is performed on the object, it can be performed without any problem.

  That is, the magnifying glass of the present invention can be used as a magnifying glass by a user wearing it with both hands or one hand open. According to this, for example, it is possible to carry a smartphone in normal use regardless of whether it is indoors or outdoors, and it is suitable for enlarging the screen in order to operate the screen and view the screen during use. is there.

  The strap can be deformed into an arbitrary shape as in the case of the plastic material, and the original shape before deformation or the shape after deformation can be maintained as it is in the state where no external force is applied.

  Further, the strap may be formed of a single material or a composite of a plurality of types of materials. In the latter case, all of the plurality of types of materials may have the same properties as described above, and if there is at least one material having the same properties, materials not having the same properties are mixed. You may do it.

(2) This invention is good also as a structure which has the attachment structure part which makes a magnifying lens detachable with respect to a strap.

  In this case, since the magnifying lens can be attached to and detached from the strap by the mounting structure portion, the magnifying lens can be detached from the strap as necessary. Thus, when disassembling the magnifying glass for carrying it, it is convenient not to get in the way when stored in a bag or other container.

  Moreover, since the magnifying lens can be attached to and detached from the strap, it can be exchanged. This makes it possible to replace the magnifying lens with a new one when it is damaged, and to change the magnification of the magnifying lens or when changing to a lens with a different design. The degree of freedom of selection is high.

(3) The present invention may be configured such that the strap forms a loop.

  In this case, if the user hangs the strap around the neck and then deforms the strap appropriately so that the magnifying lens faces the user's line of sight, the state remains unchanged and the target is maintained. By positioning the object on the other side of the magnifying lens, the user can enlarge and view the object.

  Further, since the strap forms a loop, the user can put the magnifying glass on without wearing any special means just by hanging the strap around the neck. In the state where the strap is put on the neck, there is also an advantage that the user can easily adjust the magnifying lens so that the magnifying lens faces the front of the user.

(4) In the present invention, the structure of the strap material is, in order from the center, a metal core material that undergoes plastic deformation, a spiral coil that passes through the core material, and a spiral coil that includes the core material and the spiral coil. It is good also as a structure which is the three-layer structure of resin which coat | covered.

  In this case, since the structure of the strap material is a three-layer structure, the properties of the strap are affected by each layer. That is, since the core material is made of metal and plastically deforms, the strap can be deformed and a desired shape can be maintained in a state where no external force is applied.

  In addition, the helical coil that passes through the core material is free to follow and move freely with respect to the core material even when the core material deforms (mainly bending deformation). Almost no stress due to

  Further, the plastic coil prevents the resin from coming into contact with the core material, and the core material is not directly subjected to the stress from the resin. As a result, the strap can be relatively easily deformed due to the properties derived from the core material, although the core material is included and the spiral coil and the resin layer are provided.

  In addition, the resin containing the core material and the spiral coil and covering the spiral coil protects the core material and the spiral coil, and also has a function of preventing slippage when the user wears it. The resin preferably has a small stress caused by repulsion or resistance during deformation. For example, silicon or silicon rubber can be suitably used.

(5) The present invention may have a configuration in which a partial lens having a magnification larger than that of the magnifying lens is provided in a part of the magnifying lens.

  In this case, if it is difficult for the user to visually recognize at the magnification of the magnifying lens, it is possible to view at a magnification larger than that of the magnifying lens by using a partial lens. It is easy to use because it reduces the time and effort required for replacement.

(6) The present invention may be configured such that the magnifying lens is a flat lens.

  In this case, the lens can be made thinner and lighter than a convex lens normally used for a magnifying lens, and is easy to handle. Further, since the planar lens can be made relatively easily with various designs, it can meet various needs of users.

  The present invention can be worn as a magnifying glass by a user with both hands or one hand open, and can be portable for normal use, for example, indoors or outdoors on a smartphone. A magnifier suitable for magnifying and viewing can be provided.

It is a perspective explanatory view showing one embodiment of a magnifying glass concerning the present invention. It is a disassembled perspective explanatory drawing of the magnifier shown in FIG. It is a top view of the magnifier shown in FIG. It is AA sectional drawing in FIG. It is the cross-sectional explanatory drawing which cut | disconnected the material of the strap in the length direction. It is explanatory drawing which shows the use condition of a magnifier.

The present invention will be described in detail based on the embodiments shown in the drawings.
Please refer to FIG. 1 to FIG.
The magnifying glass L includes a magnifying lens 1, a strap 2, and an attachment structure 3 that enables the magnifying lens 1 and the strap 2 to be attached / detached, that is, attached / detached.

  The magnifying lens 1 is made of acrylic resin and is a circular convex lens. In the vicinity of the outer peripheral edge of the magnifying lens 1, a fixing hole 10 for fixing to a plug 30 constituting the mounting structure 3 described later is provided so as to penetrate the front and back (see FIGS. 2 and 4). ). Since the magnifying lens 1 is made of acrylic resin, the magnifying lens 1 can be made light and can contribute to the weight reduction of the magnifying glass L.

  In the present embodiment, the diameter of the magnifying lens 1 is 128 mm. However, the diameter is not limited to this, and an appropriately sized lens can be used. As the magnifying lens 1, a glass lens can be used, and the magnification (magnification rate) can be appropriately selected as appropriate for the object to be magnified.

In addition, although not illustrated as a magnifying lens, a partial lens having a larger magnification than that of the magnifying lens may be provided in a part thereof.
A magnifying lens having a partial lens can be viewed at a magnification larger than that of the magnifying lens, for example, if the user views it with a partial lens when it is still difficult to see at the magnification of the magnifying lens. Since the trouble of changing to another lens with a large diameter is reduced, it is easy to use.

  Further, although not shown, a so-called planar lens (also referred to as a sheet lens) can be employed as the magnifying lens. Planar lenses are easy to handle because they can be made thin and lightweight. In addition, the planar lens can be made relatively easily with various designs such as an oval and a quadrilateral shape in addition to a circular outer shape (edge shape), so that it can respond to various needs of users. Can do. As the planar lens, for example, a Fresnel lens can be employed, but the present invention is not limited to this, and other known planar lenses can also be employed.

  The strap 2 has a required length and forms a loop. Specifically, the strap 2 forms a loop together with the socket 31 by being attached to a socket 31 that constitutes the attachment structure 3 described later.

  The length of the strap 2 is 1000 mm in the present embodiment, but the length is not limited to this, and can be set as appropriate according to the location to be worn by the user. Moreover, although the diameter of the material 20 of the strap 2 is 8 mm, it is not limited to this and can be set as appropriate.

  The strap 2 is deformable and has a property capable of maintaining a required shape in a state where no external force is applied, that is, a plastic property. The strap 2 has the following structure in order to give itself such a property.

Please refer to FIG.
The material 20 of the strap 2 is provided with a metal core 201 having a circular cross section in the center. The core member 201 is provided over the entire length of the strap 2 and has plasticity and strength (rigidity) that allows the user to deform the strap 2 relatively easily.
In the present embodiment, the core material 201 has a thickness of 2 mm, but the thickness is not limited to this and can be adjusted as appropriate. Further, the core material 201 is made of steel, but other metals such as aluminum may be adopted.

  The core material 201 is passed through the internal space (reference numeral omitted) of the plastic coil 202 that is a spiral coil, and is enclosed in the plastic coil 202. The plastic coil 202 also has moderate elasticity (deformability), and the plastic coil 202 can be flexibly deformed in combination with the shape-specific deformability of the coil.

  Moreover, since the plastic coil 202 can be made lightweight, it can contribute to the weight reduction of the magnifier L. The spiral coil is not limited to the plastic of the present embodiment, and other materials can be used as long as they have the necessary deformability and strength, and preferably light weight. Although a slight gap 200 is provided between the core material 201 and the plastic coil 202, a close contact structure may be used.

  A coating layer 203 made of silicon rubber, which is a resin, is provided on the outer side of the plastic coil 202 so that the plastic coil 202 is in close contact with the entire length, that is, the core material 201 is also included. The covering layer 203 is in close contact with the outer surface of the plastic coil 202 so as to enter the irregularities (not shown), and the deformation of the plastic coil 202 is limited to some extent by the flexibility of the covering layer 203. Thereby, the material 20 of the strap 2 becomes a three-layer structure. In addition, as resin which is the material of the coating layer 203, synthetic resin can be employ | adopted besides natural resin, The kind is not specifically limited.

The magnifying lens 1 and the strap 2 can be attached / detached via the attachment structure 3.
Reference is mainly made to FIGS.
The attachment structure portion 3 includes a plug 30 that fixes the magnifying lens 1 and a socket 31 that fixes the strap 2.

  The plug 30 on the side of the magnifying lens 1 is provided on an insertion body 301 having a required length of a rectangular cylinder with a permanent magnet 301a fixed at the tip, and on the back side of the upper part of the insertion body 301 (the diagonally right rear side in FIG. 2). A circular rear member 302, a circular front member 303 also provided on the front side, a rear lid 304 attached to the rear member, a front lid 305 attached to the front member 303, and a rear member 302. A fixing member 306 that is sandwiched between the front members 303 and accommodated in the gap 300 is provided. The magnifying lens 1 is integrally formed with a plug 30 and has the following structure.

  First, a fixing member 306 is fitted on the outer peripheral edge of the magnifying lens 1 on the fixing hole 10 side, and the two through holes 306 a of the fixing member 306 are aligned with the fixing hole 10. In this state, the fixing member 306 is sandwiched between the rear member 302 and the front member 303 together with the magnifying lens 1 and is accommodated in the gap 300, and each through hole 306a is a screw at the top of the front member 303 in FIG. It matches with the hole 303a. Screw holes 303 a are provided at three locations on the front member 303.

  Then, screw receivers 304 a provided at three places on the back cover 304 are inserted into through holes 302 a provided at three places on the back member 302, and the back cover 304 is attached. The screw receiver 304a at the top of the back cover 304 passes from the through hole 306a of the fixing member 306 through the fixing hole 10 of the magnifying lens 1 and the second through hole 306a. The tip of 304 a reaches the inner surface of the front member 303.

  In this state, a screw 309 is screwed into the screw receiver 304a through each screw hole 303a provided in the front member 303. Further, a stopper 305a provided on the front cover 305 is press-fitted into a stop hole 303b provided between the screw holes 303a of the front member 303, and the front cover 305 is attached. As a result, the magnifying lens 1 is fixed to the plug 30.

  Moreover, the socket 31 on the strap 2 side has a case 310 to which both ends of the material 20 of the strap 2 are fixed. The case 310 is provided with an insertion port 311 into which the insertion body 301 of the plug 30 can be inserted with a slight gap.

  The insertion port 311 does not penetrate the case 310, and a permanent magnet 310a that is magnetically attached to the permanent magnet 301a is located at the bottom (not shown) of the case 310 at a position corresponding to the permanent magnet 301a of the insert 301. It is fixed. It should be noted that the magnetic force of each permanent magnet is set to such a strength that it cannot be easily detached as long as it is pulled by the weight of the magnifying lens 1 and can be relatively easily removed by a human hand.

  According to the above structure, the integrated magnifying lens 1 and plug 30, and the integrated strap 2 and socket 31 can be attached and detached. That is, the magnifying lens 1 and the strap 2 are attached via the attachment structure portion 3 by inserting the insertion body 301 of the plug 30 into the insertion port 311 of the socket 31 and magnetizing the permanent magnet 301a and the permanent magnet 310a. Can do. The magnifying lens 1 and the strap 2 can be removed by pulling out the insertion body 301 of the plug 30 from the insertion port 311 of the socket 31.

(Function)
The operation of the magnifying glass L will be described mainly with reference to FIG.
First, since the structure of the material 20 of the strap 2 of the magnifying glass L is a three-layer structure, the properties of the strap 2 are affected by each layer. That is, since the core material 201 is made of steel and plastically deforms, the strap 2 can be deformed and can maintain a required shape in a state where no external force is applied.

  In addition, the plastic coil 202 having the core material 201 passed through the inside freely deforms and moves freely with respect to the core material 201 even when the core material 201 is bent and deformed. Almost no stress.

  Further, the plastic coil 202 prevents the core material 201 from coming into contact with the silicon rubber of the coating layer 203, so that the core material 201 is not directly subjected to stress from the resin. Thereby, although the core material 201 is included and the plastic coil 202 and the covering layer 203 are present, the strap 2 can be relatively easily deformed due to the properties derived from the core material 201.

  In addition, the silicon rubber of the coating layer 203 that encloses the core material 201 and the plastic coil 202 and covers the plastic coil 202 protects the core material 201 and the plastic coil 202, and also prevents slippage when the user wears it. It also has a function. Since silicon rubber is used for the covering layer 203, the stress caused by repulsion or resistance during deformation is relatively small and can be easily deformed. Silicone rubber also has the advantage of being gentle to the skin and hardly affecting the skin of the user.

  As a result, the magnifying glass L has the property that the strap 2 can be deformed and can maintain the required shape in the state where no external force is applied, so that the user H uses his / her hand as shown in FIG. It can be transformed into a shape that does not interfere with the work and can be worn around the neck.

  And while maintaining the state, the user H holds the smartphone 4 as an object with both hands free, and is positioned on the other side of the magnifying lens 1 as viewed from the user H. The screen of the smartphone 4 can be enlarged and viewed.

  At this time, since the user H can freely use both hands, the user can easily place the smartphone 4 held by the hand on the other side of the magnifying lens 1, and is magnifying. Even when the smartphone 4 is operated, it can be performed without any trouble.

That is, the magnifying glass L can be used as a magnifying glass by the user H wearing it with both hands or one hand open. According to this, it is possible to carry in the normal use of the smartphone 4 regardless of whether it is indoors or outdoors. It is suitable for enlarging and viewing.
Alternatively, the strap 2 can be appropriately deformed, placed on a desk or the like as a stand, and used with the magnifying lens 1 so that the screen of the smartphone 4 or the like can be viewed in an enlarged state.

  Further, since the magnifying lens 1 and the strap 2 can be attached and detached, the magnifying lens 1 or the strap 2 can be exchanged. As a result, for example, when the magnifying lens 1 is damaged, it can be replaced with a new one. When the magnification of the magnifying lens 1 is to be changed or when the lens is changed to a different design, it can be replaced. The degree of freedom in selecting a magnifying lens is high.

  The terms and expressions used in this specification are merely explanatory and are not limiting at all, and exclude terms and expressions equivalent to the features described in this specification and parts thereof. There is no intention to do. Further, it goes without saying that various modifications are possible within the scope of the technical idea of the present invention.
