Abstract
Description
[Technical Field]
[0001] The present invention relates to an external magnifying glass unit, and relates to a notebook-style case, for example. [Background technology]
[0002] Smartphones (short for smartphone) have a function to enlarge the displayed objects (such as text or photos) on the screen, but people with poor eyesight or presbyopia still find it difficult to see the displayed objects clearly. Also, using the smartphone's enlargement function narrows the display range of the displayed object (for example, if the displayed object is a string of characters, the number of characters displayed will be reduced), which can make it more difficult to see. Summary of the Invention [Problem to be solved by the invention]
[0003] People with presbyopia or poor eyesight who do not use the smartphone's magnification function may have to take off their glasses or put on reading glasses every time they look at the smartphone screen. This issue can also occur with tablets, books, etc., in addition to smartphones. [Means for solving the problem]
[0004] An external magnifying glass unit is constructed that can be attached to an object to be viewed, such as a smartphone. The magnifying glass unit includes a rectangular magnifying glass and a support portion. The support portion includes a first side portion, a second side portion, and a middle portion. The first side portion extends in a first direction and is provided on one side of the magnifying glass. The second side portion extends in the first direction and is attached to the object to be viewed, or is attached to the case of the object to be viewed, or is provided in advance. The middle portion connects one end of the first side portion to one end of the second side portion. In a first state of the magnifying glass unit, the middle portion stands with one end of the second side portion as its base end, and the support portion maintains the magnifying glass parallel to the surface of the object to be viewed. A user views the display range of the object to be viewed through the magnifying glass. The display object is magnified for the user through the magnifying glass. [Effects of the Invention]
[0005] For people with poor eyesight or presbyopia, the displayed object can be seen without having to put on or take off glasses. [Brief explanation of the drawings]

[0007] Several embodiments of the present invention will be described below. [First embodiment]
[0008] FIG. 1 is a diagram showing a smartphone case according to the first embodiment in an open state.
[0009] The type of smartphone and magnifying glass are acceptable. The magnifying glass can be made of any material, such as glass or plastic. A magnifying glass that blocks blue light may also be used. The magnifying glass and smartphone case are organically connected by a hinge or wire.
[0010] Figure 2 is a top view of the magnifying glass set up, and Figure 3 is a side view of the magnifying glass set up.
[0011] To actually magnify the object displayed on the display screen, the front side of the smartphone case is raised toward you and the magnifying glass is placed on the smartphone's display screen. By placing the magnifying glass between the smartphone's display screen and your eyes, the object displayed on the smartphone screen can be seen magnified.
[0012] The magnification may be changed depending on the user's condition. The magnifying glass may also be replaced depending on the magnification. The magnifying glass may also be able to be slid up and down to adjust the magnification. The setting position will vary depending on the smartphone screen and the magnification of the magnifying glass. The magnifying glass may also be removed from the smartphone case and used when viewing something other than the smartphone screen.
[0013] Figure 4 shows the front side of the smartphone case when the magnifying glass is stored inside.
[0014] As shown in Figure 4, when the smartphone is not in use, the smartphone case is closed and the magnifying glass is stored in the smartphone case. When the magnifying glass is stored in the smartphone case, the internal mechanism (magnifying glass frame, etc.) is completely or almost invisible. There are various ways to set the magnifying glass in the smartphone case.
[0015] Figure 5 shows the back of the smartphone case with an auxiliary belt that makes it easier to hold the magnifying glass.
[0016] When using the magnifying glass, it is necessary to open the front side of the smartphone case, which can prevent difficulty in gripping the smartphone. Also, as shown in Figure 5, in addition to the auxiliary belt, a smartphone case holding magnet may be provided. While using the smartphone, the auxiliary belt for holding the case can be attached to the magnet on the back.
[0017] Figure 6 shows the front side of a smartphone case, with only the frame on the front side of the smartphone.
[0018] In other words, the front side of the smartphone case can be just a frame, so that the smartphone screen can be viewed without opening the front side. The front side of the smartphone case can be transparent glass or film.
[0019] Figure 7 shows the magnifying glass in the middle of being stored. Figure 8 shows the smartphone case in the middle of being closed from the open state. The order in which the magnifying glass is actually closed after use is Figure 2 → Figure 7 → Figure 1 → Figure 8 → Figure 4. The order in which it is opened is the reverse of the order in which it is closed.
[0020] The above is a description of the first embodiment of the present invention. The above description can be summarized, for example, as follows. The following summary may include supplementary explanations and explanations of modifications to the above description.
[0021] A notebook-style case has a cover (e.g., a front cover or a front flap) that overlaps the surface of a smartphone (an example of an object having a display range) when closed, a back cover (e.g., a back cover or a back flap) on which the back of the smartphone is placed, and a connecting part (e.g., equivalent to the "spine" of a book) that connects one side of the cover and one side of the back cover, and this notebook-style case also has a magnifying glass. Magnifying glasses are typically rectangular in plan view, but shapes other than rectangular may also be used.
[0022] A first side of the magnifying glass is associated with a first side of the cover opposite to a second side connected to the connecting portion so that the magnifying glass can be opened and closed. For example, a plurality of hinges may be provided along the first side of the cover, and the first side of the magnifying glass may be provided on those hinges.
[0023] A second side of the magnifying glass, which is the side opposite to the first side, is associated with a first side of the back cover, which is the side opposite to the second side connected to the connecting portion, by an association means. The association means is, for example, a U-shaped wire. One or more tubes through which the wire passes may be provided on each of the second side of the magnifying glass and the first side of the back cover. The first side of the U-shaped wire is associated with the second side of the magnifying glass (for example, passing through the tube), and the second side of the U-shaped wire is associated with the first side of the back cover (for example, passing through the tube).
[0024] When the smartphone case is closed, the magnifying glass closes against the cover. For example, the magnifying glass closes to the cover, and the wire on the U-shaped side lies flat.
[0025] When the smartphone case is opened, the magnifying glass is positioned above the display screen (an example of the display range) on the surface of the smartphone. For example, when the smartphone case is opened, the U-shaped wire rises, so that the magnifying glass is positioned above the display screen of the smartphone, and the third side of the U-shaped wire, which connects the first side and the second side, supports the magnifying glass.
[0026] When the smartphone case is opened at a predetermined angle (for example, 90 degrees), it is preferable that the entire area of the magnifying glass covers the entire area of the display screen when viewed from above.
[0027] The U-shaped wire leaves one side open, so you can insert your finger between the magnifying glass and the smartphone to operate the smartphone's display screen. When the smartphone case is closed, the magnifying glass and wire fit into the smartphone case without protruding significantly (preferably not at all).
[0028] Magnifiers of different magnifications may be available, for example, there may be a plurality of magnifiers of different magnifications, and the magnifiers may be removable and replaced with new or different magnifications as appropriate.
[0029] The smartphone case may be provided with a means for adjusting the height of the magnifying glass when the smartphone case is open. For example, the height of the magnifying glass may be adjusted by sliding it along a wire or by other means. The magnifying glass may be a blue light blocking magnifying glass.
[0030] The cover of the smartphone case may be just a frame, or may be made of transparent glass or film, so that the display screen of the smartphone can be seen even when the smartphone case is closed.
[0031] The present invention may also be applied to notebook-style cases other than smartphone cases, such as notebook-style cases for tablet devices, books, etc.
[0032] 9 to 12 may be adopted as a second embodiment of the present invention. The second embodiment may be combined with at least a part of the first embodiment. At least a part of the description of the second embodiment may be applied to the first embodiment. [Second embodiment]
[0033] That is, as can be seen when the smartphone case is changed from a closed state (see FIG. 9) to an open state (see FIG. 10), first and second wires are attached to the smartphone case. Both the first and second wires are U-shaped (or U-shaped) wires. The wires may be made of, for example, bent wire.
[0034] Each of the first and second wires may have the following configuration. That is, the wires may be composed of first and second long portions that are parallel to each other and extend in the longitudinal direction of the smartphone case, and a third portion that connects the upper ends of the first and second long portions. A portion of the first wire may be connected to the second wire. One side of the magnifying glass may be fixed to only at least one long portion of the first wire.
[0035] When the magnifying glass is not in use, the entire first wire may be attached to the back of the cover of the notebook-style smartphone case, and the entire second wire may be attached to the surface on which the smartphone is placed, for example, so as to surround the smartphone, as shown in Figure 10. This allows the overall thickness of the smartphone case to be reduced when it is closed.
[0036] When using the magnifying glass (a state in which touch operations on the smartphone screen are possible while viewing the smartphone screen through the magnifying glass), as shown in Figures 11 and 12, one long end of the first wire and one long end of the second wire each serve as the base end (i.e., are attached to the smartphone case), and the other long end of the first wire and the other long end of the second wire are attached to the left and right edges of the magnifying glass. This causes the first and second wires to stand up and support the magnifying glass. That is, one long end of each of the two wires serves as the base end, and the third portion of each of the two wires extending upward from one end of the two base end portions and the other long end of each of the two wires create space on both the left and right sides between the magnifying glass and the smartphone screen large enough to insert a hand. This allows a hand (at least a finger) to be inserted from either the left or right side to perform touch operations on the smartphone screen.
[0037] The smartphone case and magnifying glass may be made separately and can be set up at a later date, or the magnifying glass and the first and second wires may be detachable or attachable to the smartphone case later.
[0038] 13 to 17 may be adopted as a third embodiment of the present invention. The third embodiment may be combined with at least a part of the first and second embodiments. At least a part of the description of the third embodiment may be applied to the first or second embodiment. [Third embodiment]
[0039] 13 and 14, a U-shaped wire is provided on the smartphone case. Unlike in FIG. 12, only one wire is required in this embodiment.
[0040] The U-shaped wire is composed of a first longitudinal portion, a second longitudinal portion, and a third portion connecting the first and second longitudinal portions. The lengths of the first and second longitudinal portions of the wire are typically the same, but may be different.
[0041] The magnifying glass can be the same size as the front and back covers, which is expected to cover the entire display screen of a smartphone placed behind the back cover (an example of the display range of an object).
[0042] One side of the magnifying glass is associated with (e.g., connected to) a first long portion of the U-shaped wire, and one side of the back cover is associated with (e.g., connected to) a second long portion of the U-shaped wire.
[0043] Specifically, first and second fixing means are provided. In this embodiment, each fixing means is a means for fixing by mechanical connection. Both the first and second fixing means have a concave-convex connecting part, specifically a connecting part (e.g., a short fixing tool) with a concave portion and a connecting part (e.g., a short fixing tool) with a convex portion that can fit into the concave portion. Both connecting parts are tubular (e.g., cylindrical) members, and the first longitudinal portion or the second longitudinal portion of the wire passes through a cavity (inside the tube) of the connecting part.
[0044] The connecting part of the recessed portion (or the connecting part of the protruding portion) of the first fixing means may be fixed by adhesive or the like to any location (for example, near one side edge) of the magnifying glass. The connecting part of the protruding portion (or the connecting part of the recessed portion) of the first fixing means may be fixed by adhesive or the like to any location of the first longitudinal portion of the wire. The recessed portion is provided at one end of the tubular member serving as the connecting part, and the protruding portion is provided at the other end of the tubular member of the connecting part. These connecting parts are arranged so that one end of the connecting part of the recessed portion (the end having the recessed portion) and the other end of the connecting part of the protruding portion (the end having the protruding portion) face each other.
[0045] The connecting part of the recessed portion (or the connecting part of the protruding portion) of the second fixing means may be fixed to any location on the smartphone case (for example, the connecting portion or the inside surface of the back cover) by adhesive, etc. The connecting part of the protruding portion (or the connecting part of the recessed portion) of the second fixing means may be fixed to any location on the smartphone case by adhesive, etc., along the second longitudinal portion of the wire.
[0046] When the case is open, the U-shaped wire is raised, positioning the magnifying glass above the smartphone display screen, and a third portion of the U-shaped wire supports the magnifying glass. In this state, the front surface of the case may be folded over the back surface of the case. Because the magnifying glass is supported above the case by a single U-shaped wire, you can insert your finger into the case and operate the smartphone display screen without any problems from either the side with the wire or the side without the wire.
[0047] To prevent the supported magnifying glass from tilting when the case is open, one side of the magnifying glass is fixed relatively to a first long portion of the U-shaped wire by a first fixing means, and to prevent the U-shaped wire from falling over, a second long portion of the U-shaped wire is fixed relatively to one side of the back cover by a second fixing means.
[0048] While any of the fastening means may be a means for fastening by any method, such as friction, magnets, or mechanical connection, this embodiment employs a concave-convex connecting part as an example of a fastening means by mechanical connection. In this embodiment, the wire or at least one of the connecting parts is rotated relatively around the longitudinal axis (and one connecting part is moved relatively along the wire so as to contact the other connecting part), so that the convex part fits into the concave part, resulting in fastening. When closing the case, the wire or at least one of the connecting parts is rotated relatively around the longitudinal axis (and one connecting part is moved relatively along the wire so as to move away from the other connecting part), so that the fit of the convex part into the concave part is released (the convex part is separated relatively from the concave part), resulting in release of fastening. The relative rotation around the longitudinal axis may be rotation of the wire or rotation of the connecting part.
[0049] The U-shaped wire is an example of a U-shaped linear or rod-shaped member. In addition, the positioning of the magnifying glass above the smartphone display screen may mean that the magnifying glass overlaps the entire smartphone display screen in a plan view from above.
[0050] 18 to 25 may be adopted as a fourth embodiment of the present invention. The fourth embodiment may be combined with at least a part of the first to third embodiments. At least a part of the description of the fourth embodiment may be applied to at least one of the first to third embodiments. [Fourth embodiment]
[0051] FIG. 18 is a top perspective view of a magnifying glass unit according to the fourth embodiment set on a smartphone.
[0052] In this embodiment, the magnifying glass unit is attached directly to the smartphone (or to the smartphone case). The magnifying glass unit includes a magnifying glass and a U-shaped support. The U-shaped support is composed of first and second side portions that form parallel portions of the U-shape, and an intermediate portion that connects one end of the first side portion to one end of the second side portion. The first side portion is attached to one side of the magnifying glass. The second side portion is attached to the side (or back) of the smartphone (e.g., by a magnet, etc.). Each of the first and second side portions rotates at least 90° (e.g., up to 180° or 360°). According to the state shown in FIG. 18, in the first state of the magnifying glass unit, the intermediate portion stands with one end of the second side portion as its base end, and the support portion maintains the magnifying glass parallel to the smartphone screen. The U-shape creates height, which leaves a gap between the magnifying glass and the smartphone screen, allowing you to insert your fingers into that gap and operate the smartphone screen without any difficulty.
[0053] FIG. 19 is a rear view of the smartphone on which the magnifying glass unit according to the fourth embodiment is set.
[0054] This drawing relates to a modified example of the connection of the second side portion to the smartphone. That is, in FIG. 18, the second side portion is adhered to the side of the smartphone, while in FIG. 19, the second side portion is connected to the back of the smartphone. The back of a smartphone generally has a large amount of free space other than the camera. For example, as shown in FIG. 19, one side of the back of the smartphone has an empty space extending from top to bottom. The second side portion is connected to at least a portion of that empty space. This connection may be detachable. For example, this connection may be realized by a magnet or a holding-type connection (e.g., a clip connection).
[0055] FIG. 20 is a top view of the smartphone in which the magnifying glass unit is set, with the smartphone magnifying glass folded.
[0056] Since each of the first and second side portions rotates at least 90°, the state of the magnifying glass unit can be changed from the state shown in Fig. 18 to the state shown in Fig. 20, or conversely, from the state shown in Fig. 20 to the state shown in Fig. 18. According to Fig. 20, the U-shaped support part can be folded when the smartphone is not in use.
[0057] Fig. 21 is a diagram showing a first example of an extension mechanism for the middle part of a U-shaped support part, Fig. 22 is a diagram showing a second example of an extension mechanism for the middle part of a U-shaped support part, and Fig. 23 is a diagram showing a third example of an extension mechanism for the middle part of a U-shaped support part.
[0058] The intermediate portion has an expansion mechanism that enables expansion and contraction of the intermediate portion. Various configurations of the expansion mechanism are conceivable, and any configuration may be adopted.
[0059] For example, in the telescopic mechanism according to the first example shown in Fig. 21, the intermediate section has a rod-shaped section and a container section in which a part of the rod-shaped section is housed. The rod-shaped section moves in the longitudinal direction within a predetermined range of the length of the container section, thereby telescopically extending the intermediate section.
[0060] 22 shows a second example of an extension mechanism, in which the intermediate section has two rod-shaped sections and a tubular section into which a portion of each of the two rod-shaped sections is housed from both sides. The rod-shaped sections move in their longitudinal directions within a predetermined range of the length of the tubular section, thereby extending and contracting the intermediate section.
[0061] According to the third example of the telescopic mechanism shown in Figure 23, the intermediate section has a mechanism in which multiple tubular members are connected in an axially nested manner and slide relative to each other to change the length. Each member is in the relationship of an inner tube and an outer tube, and can be fixed at a desired position by friction or a locking mechanism.
[0062] 24 and 25 are diagrams showing the configuration of the first and second side portions of the U-shaped support portion.
[0063] Each of the first and second side sections has a side section body that is part of the U-shaped support section and extends in one direction, and a side section body holder that extends in the same direction and covers at least a portion of the side section body. The side section body holder has, for example, a slit extending in its length direction, through which the side section body is fitted into the side section body holder. A portion of the side section body has a protrusion (an example of a convex portion) that extends in a direction perpendicular to the length of the side section body. The protrusion may be continuous in the length direction or may be scattered along the length direction. The side section body holder has a groove (an example of a concave portion) into which the protrusion of a side section body rotated 90 degrees, for example, fits. As a result, when the protrusion fits into the groove, the side section body will not rotate unless a force greater than a predetermined magnitude is applied. This combination of protrusion and groove corresponds to an example of a locking mechanism. Note that the protrusion may be provided on the side section body holder and the groove may be provided on the side section body. The side body holding portion is a tube having the above-mentioned slit extending in its length direction, and frictional resistance occurs due to friction between the inner surface of the tube and the surface of the side body (for example, a cylindrical member).
[0064] The second side portion that is attached to the smartphone itself (or the smartphone case) may be provided with an attachment member for attachment to the smartphone (or smartphone cover). The attachment member may be attached to the second side portion, for example, by sliding it from one end side (or the other end side) of the second side portion. The attachment member is attached to the side or back side (or the top side) of the smartphone, for example. Any method of attachment may be used, such as double-sided tape, a magnet, a suction cup, or a hook. The attachment location may also be anywhere. If a detachable attachment is used, the magnifying glass unit can be removed from the smartphone and stored when the smartphone is not in use.
[0065] Although several embodiments have been described above, these are merely examples for explaining the present invention, and it is not intended that the scope of the present invention be limited to these embodiments. The present invention can be implemented in various other forms.
[0066] For example, the above description can be summarized as follows: The following summary may include supplementary explanations and explanations of variations of the above description.
[0067] Although a smartphone is used as the visual object, other visual objects such as a tablet or a book may also be used. The visual surface of the visual object (e.g., the screen of a smartphone or tablet PC, or the page of a book) is typically rectangular, and therefore the magnifying glass is also typically rectangular. The size of the magnifying glass is preferably a size corresponding to the visual object, for example, preferably a size equal to or larger than the visual surface.
[0068] Furthermore, the external magnifying glass unit that is attached to the object to be viewed may be attached to a smartphone (for example, to the side, back or top) (for example, the fourth embodiment), or may be a unit that is attached to a smartphone case, or may be a unit that serves as a case for the object to be viewed (for example, a notebook-type or box-type case) (for example, the first to third embodiments).
[0069] The magnifying glass unit includes a magnifying glass and a support portion. The support portion includes first and second side portions and an intermediate portion. The first support portion extends in a first direction and is provided on one side of the magnifying glass. The second side portion extends in the first direction and is attached to the object to be viewed, or is attached to the case of the object to be viewed, or is provided in advance. The intermediate portion connects one end of the first side portion to one end of the second side portion. In a first state of the magnifying glass unit, the intermediate portion stands with one end of the second side portion as its base end, and the support portion maintains the magnifying glass parallel to the viewing surface of the object to be viewed. The magnifying glass is an optical component for magnifying and viewing an object to be viewed, such as a smartphone, tablet, or book, and includes at least one magnifying lens. The magnifying lens may be a Fresnel lens, which is thin and lightweight, but is not limited to this. Any type of lens may be used, such as a convex lens, an aspherical lens, a compound lens (an optical lens with a multi-layer structure), etc. The optical material may be any material selected from optical glass, acrylic resin, polycarbonate, or a composite material thereof.
[0070] Each of the first side portion and the second side portion may be rotated at least 90° around an axis along the first direction as a rotation axis. The first state may be a state in which the intermediate portion stands with one end of the second side portion as a base end, and each of the first side portion and the second side portion is rotated 90° (e.g., FIG. 16 or 18).
[0071] At least one of the first side portion and the second side portion may have a side body extending in a first direction and a side body holding portion extending in the first direction and covering at least a portion of the side body. The support portion may have a locking mechanism that fixes the side body when the side body is rotated 90 degrees.
[0072] In the second state of the magnifying glass unit, the middle portion may be tilted down with one end of the second side portion as a base end, and the magnifying glass may be in contact with the object to be viewed.
[0073] The support portion may be U-shaped, and the intermediate portion may be a member extending in a second direction that is perpendicular to the first direction, and may have an extension / contraction mechanism that allows the intermediate portion to extend and contract along the second direction.
[0074] Each of the first and second side portions may be referred to by other names, for example, as a leg portion.
[0075] Also, for example, there may be one U-shaped support part, or two as shown in Fig. 12. In the latter case, the support parts may include a first support part and a second support part, with the first side part of the first support part being provided on a first side of the magnifying mirror, and the first side part of the second support part being provided on a second side of the magnifying mirror, the second side of the magnifying mirror being the side opposite the first side of the magnifying mirror. Each of the first and second support parts may be the support part described above.
[0076] Also, for example, the shape of the support part does not necessarily have to be U-shaped, and can be any shape that provides enough free space between the object to be viewed and the magnifying glass to insert a finger, for example, a U-shape.
[0077] Furthermore, for example, the support portion having the first and second side portions and the intermediate portion may be called an arm (e.g., a U-shaped arm), and the second side portion may be attached (e.g., detachably attached) to at least a portion of the outer periphery or back surface of the visual object (e.g., a smartphone) itself, or to at least a portion of the outer periphery or back surface of the case of the visual object. Examples of the attachment structure include at least one of the following modes (a) to (f). (a) A configuration in which a clip mechanism is provided at the end of the second side portion, and the clip mechanism is attached by clamping the side edge of the object to be viewed (or the side edge of the case of the object to be viewed). (b) A configuration in which an adsorption pad (for example, a gel pad or a suction cup) is provided at the end of the second side portion, and the device is attached by adsorption to the back surface of the object to be viewed (or the back surface of the case of the object to be viewed).
