Description

INDUSTRIAL APPLICABILITY In the present invention, a mobile electronic device such as a smart phone, a tablet-type personal computer, or the like can be held stably with one hand, has a simple structure, is easy to install, and is always installed. The present invention relates to a portable electronic device holder which does not get in the way even when

When a portable electronic device is held and used with one hand, the thumb must be removed to operate the push buttons or the touch panel, which makes the holding state of the portable electronic device unstable. Various holders, holders, grips, and hand straps have been proposed to avoid such a situation and stably hold the camera with one hand.

For example, in the portable information device holder disclosed in Patent Document 1, recessed portions of hanging hooks having a substantially U-shaped or substantially L-shaped side surface are opposed to both ends of an elastic band made of a belt-like elastic fabric, and the elastic band is and the retaining hook are fixed by a connecting member, and are detachably attached to the back surface of the case of the portable information device.

The advantage of this is that when held with one hand, the finger is pressed by the elastic band, so that it can be held stably. However, the hanging hooks and connecting members protrude from the surface of the case of the portable information device, and there is a problem that it becomes a hindrance when it is stored. rice field.

Further, for example, a holder for a portable electronic product disclosed in Patent Document 2 is composed of a slide member, an arm member, a base member, and a guide member. The end of the slide material forms a movable slide material storage space between the part and the base material, and is movable. By standing up, we propose a structure that forms a gap where a finger can be inserted to hold it stably with one hand.

This has the problem that the number of members is large and the structure is complicated. Furthermore, since the size of the gap can be freely changed within a certain range, when the finger is inserted, it does not press down on the finger like the elastic band of Patent Document 1, so an extra gap is created and it is not possible to hold it stably. I had a problem.

In the following description, the symbols with alphabetical suffixes to the numbers are omitted in the description in one drawing, and the alphabetical parts are different and the same number means a plurality of symbols at the same time. I have something to do. For example, when writing the holding member 21, it means both the holding member 21a and the holding member 21b.
In the description of reference numerals, a to d are used to omit consecutive a, b, c, and d.

In the drawings, the view from the thickness direction of the holding member is a plan view, the view from the width direction of the holding member is a side view, and the view from the longitudinal direction is a front view.
In the following description, both the housing of the portable electronic device and the case that houses the portable electronic device may be referred to simply as a case.

In the present invention, it is premised that the main body composed of the parts, circuits, boards, etc. of the portable electronic device is covered with a housing, or is further housed in a case for the purpose of protection. A portable electronic device holder is composed of a combination of a body and a holding member, or a portable electronic device holder is composed of a combination of a case and a holding member, and finally holds a portable electronic device. However, there are both cases in which the case is held directly.

In the first aspect of the present invention, as shown in FIG. 1, for example, the portable electronic device holder includes a housing of the portable electronic device to be held or a case 2 for housing the same, and a sheet-like elastic body. , and a holding member 21 that is an independent member, and are configured by fixing a plurality of fixing portions 213 of the holding member 21 to the housing of the portable electronic device or the case 2 that houses it, and connecting them. Elasticity refers to the ability of an object to return to its original shape when the force is removed.

In a second aspect of the present invention, the portable electronic device holder has a plurality of (here, two parallel) cutouts in a surface material forming a housing or case of the portable electronic device, as shown in FIG. 10, for example. A shape (here, a rectangular shape) formed by combining rectangles is left uncut by making a hole, and is used as a holding member to constitute a portable electronic device holder. In this aspect, there is no need to connect the holding member by fixing it to the housing or the case.

In the case of the second aspect, the fixed part, which is part of the holding member, is considered to be integral with the material of the housing or case from the beginning, rather than being fixed to the housing or case afterwards.
Moreover, since the material of the holding member is the same as that of the housing or case, the housing or case must be made of an elastic material.

The basic structure and operation of the portable electronic device holder will be described according to the first aspect. FIG. 1 is a diagram showing the outer shape of a rectangular holding member 21a. The holding member 21a is fixed to the surface of the case 2a of the portable electronic device at the fixing portions 213a, which are both end portions, by an appropriate means such as adhesion, adhesion, or crimping (not shown) so as not to be separated. This state means that the holding member is fixed to the housing or case of the portable electronic device to be held.

A portable electronic device has a surface on which a display or the like is installed on the other side in the figure. Also, it is housed inside the case 2a and is not visible in this figure.

Portions other than both ends of the holding member 21a are not fixed to the housing or case 2a. When no external force is applied, the holding member 21a extends straight along the surface of the case 2a to be held, as shown in FIG. 1(b).

As shown in FIG. 1(c), when an upward force is applied to the flat portion 213a, which is the unfixed portion between the fixed ends, as indicated by the arrow in the figure, the holding member 21a is It has elasticity, so it stretches in the longitudinal direction. As a result, a gap is formed between the holding member 21a and the case 2a.

By appropriately selecting the length and the elastic modulus of the holding member 21a when no force is applied, this gap becomes large enough to insert a finger or an arm. When a finger or arm is passed through the gap, it is firmly pressed against the object to be held by the force of the holding member 21a trying to return to its original state, so the object to be held can be held stably.

Here, when the elastic modulus of the material of the holding member itself is large (that is, when it is hard and does not stretch), a part of the holding member in the longitudinal direction is more deformed with the same force than the other parts. That is, the extension portion, which is a portion with a small elastic modulus, is arranged. FIG. 2 is an outline drawing of a retaining member with extensions. As shown in FIG. 2(a), which is a plan view, a part of the holding member in the longitudinal direction is alternately cut in the width direction from both sides to form an extended portion 211b with a reduced apparent elastic modulus. By doing so, the elastic modulus can be corrected.

Here, the term "low modulus of elasticity" includes the apparent modulus of elasticity due to the arrangement of such extensions. As will be described later, there are structures other than those described here in which cuts are formed to form a structure with a small elastic modulus, but structures using cuts are collectively referred to as cut structures.

According to FIG. 2(c), which is a side view, it can be seen that the extended portion 211b of the holding member 21b is deformed.
Furthermore, in FIG. 8, it is possible to stereoscopically see a state in which the holding member 21b having the extended portion 211b is deformed in the longitudinal direction and the thickness direction as a result of the force being applied.

In FIG. 8, as indicated by arrows, the holding member 21b, which is fixed to a case (not shown), has fixed portions 213b at both ends thereof, and a force directed in the opposite direction is applied to the flat portion 212b at the center. In the figure, a force is applied toward the front. It can be seen that the force deforms the expanded portion 211b and opens the cut 214b, thereby deforming in the longitudinal direction and the thickness direction.

According to this structure, even if the deformation of the individual parts is small, many of them can be gathered and the expansion part can be greatly stretched in the longitudinal direction. The structure of the cut is not limited to that shown in FIG. 2 and the like. For example, a structure in which cuts extending in the width direction are arranged in a houndstooth pattern may be used. That is, the apparent modulus of elasticity can be adjusted in a wide range by appropriately selecting the structure of the cuts, the locations of the cuts, the number of cuts, the distribution of the cuts, and the like.

3 and 4 are sketches of situations in which a portable electronic device holder is used to hold a portable electronic device. As an example, the holding member 21a or the holding member 21b is fixed to the back side (the front side in the figure) of the case 2 of the mobile electronic device such as a smartphone, where there is no display, and the mobile electronic device is held with one hand. ing. The user's face (not shown) is on the other side of the drawing, and the user is looking at the screen of the display.

3 or 4, the third finger 73 and the fourth finger 74 are passed through the gap between the extended holding member 21a or the holding member 21b and the case 2 of the portable electronic device, and the second finger 72 and the fifth finger 75 are inserted. is placed outside the gap. The third finger 73 and the fourth finger 74 are pressed against the case 2 of the portable electronic device due to the tensile stress and bending stress generated by the deformation of the holding member 21a or the holding member 21b, which directly affects the portable electronic device. The case 2 and finally the portable electronic device housed in the case 2 are stably held with one hand.

As can be seen from the figure, the first finger (thumb) 71 can be released and moved freely. Therefore, the touch panel or the like on the front side of the portable electronic device on the other side of the case 2 in the drawing can be easily operated in a wide range.

3 and 4 show an example in which the holding member 21a or the holding member 21b is attached to the case 2, respectively, but the case 2 can also be regarded as a housing of the portable electronic device. It may be viewed as a state in which the holding member is directly attached.

When the finger is removed from the gap between the holding member 21a or the holding member 21b and the case 2 of the portable electronic device, the holding member 21a or the holding member 21b returns to its original length due to its elasticity, and follows the surface of the object to be held. Become.

The sheet-shaped holding member is not limited to the method of cutting out from a sheet-shaped material, but can also be produced as a member independent of the case by molding a polymeric material with a mold or using a three-dimensional printer or the like. .

It should be noted that although the holding member 21 is fixed to the case 2 here, the case can be replaced by the case of the portable electronic device.

Although the shape of the holding member has been described here as being rectangular (I-shaped), the shape is not limited thereto. As will be described later, specific examples may include V-shape, Y-shape, substantially triangular shape, X-shape and modifications thereof.

According to the present invention, the portable electronic device can be stably held with one hand, and there is little danger of dropping it. Since the thumb is not used for holding, there are no restrictions on movement and the range of operation is expanded. It has a simple structure and can be easily attached to the housing of the target portable electronic device or the case that houses the portable electronic device. Therefore, it does not get in the way when the portable electronic device is stored in a pocket or the like, and it is possible to realize a portable electronic device holder that is easy to manufacture and low in cost.

This embodiment corresponds to the mode 1 described in (Means for Solving the Problems). The portable electronic device holder of the present invention is composed of a housing containing a main body of the portable electronic device or a case for housing the portable electronic device, and a holding member fixed thereto. That is, the housing or case itself forms part of the electronic device holder.

In this embodiment, the holding member is a sheet-like, independent member regardless of the manufacturing method. The shape of the holding member is rectangular (I-shaped).

FIG. 1 shows an outline drawing of a rectangular holding member. The holding member is the primary member of the portable electronic device holder. As can be seen from the plan view of FIG. 1(a), the holding member 21a is in the form of a rectangular sheet, extends in the longitudinal direction (right and left in the figure) in a belt shape, and is made of an elastic material.

As shown in FIG. 1(b), which is a side view, a holding member is provided on the rear surface of the case 2a of the portable electronic device to be held, which is the opposite side (upper side in the figure) to the front side where the display and the like are installed. 21a is fixed. That is, both ends of the holding member 21a are defined as two fixed portions 213a, which are fixed by adhering them to the surface of the case 2a with an adhesive 215a, thereby connecting the holding member 21a and the case 2a. This state is referred to as fixing a plurality of locations of the holding member to the housing or the case.

The two fixed portions 213a are adhered and fixed respectively by an adhesive 215a at a position where the holding member 21a has a natural length when no force is applied from the outside. As shown in FIG. 1B, which is a side view, other parts of the holding member 21a than the part fixed by the adhesive 215a are not fixed to the case 2a of the portable electronic device. In the figure, the thickness of the adhesive 215a is exaggerated for clarity.

In this manner, the holding member 21a is connected to the case 2a to be held, thereby forming a portable electronic device holder.

Any suitable method, such as adhesive, adhesive tape, adhesive sheet, self-adhesive film, etc., may be used as long as it has a function of fixing the holding member, without being limited to the adhesive 215a.
When the holding member is fixed with an adhesive, it has the advantage that it can be peeled off from the housing or case when it is no longer needed or when the position of the holding member is to be changed.

The dimensions of the holding member 21a vary depending on the size and application of the portable electronic device to be held. The width should be about 15 to 25 mm. When the arm is used, the length should be about 200 to 250 mm and the width should be about 30 to 50 mm. The thickness is about 0.5 to 2 mm, and the optimum thickness is selected in consideration of the degree of elasticity of the material.

The material of the holding member is a sheet-like material or a sheet-like material that can be processed into a sheet-like shape, has a certain degree of thickness, has necessary elasticity, and can be easily bent with fingers, such as a thermoplastic polyurethane resin, Appropriate materials such as polyamide resin, low-density polyethylene resin, flexible fluororesin, and resin such as silicon rubber can be used.

As a means for producing the holding member 21a, an appropriate means may be selected from a method of cutting out from a sheet material, a method of molding using a mold, a method of producing with a three-dimensional printer, and the like. The material of the holding member is the same for Examples 2, 3 and 4 to be described later. The creation means is the same for the second embodiment.

The operation of the portable electronic device holder of this embodiment will be described. As shown in FIG. 1(b), the holding member 21a extends along the surface of the case 2a of the portable electronic device when no external force is applied. When it's along the surface, that is, when it's not in use, it's thin so it doesn't get in the way of storage.

As shown in FIG. 1(c), when an upward force is applied to the unfixed flat portion 213a in the center of the holding member 21a as indicated by an arrow, the tensile force causes deformation, and the whole is seen from the side. , a mountain shape is formed with the fixing portion 213a as the foot of the mountain. As a result, a gap is formed between the holding member 21a and the surface of the case 2a of the portable electronic device or the like. A user's finger or arm can be inserted into this gap.

FIG. 3 is a sketch of a situation in which a mobile electronic device holder using a holding member 21a with a small elastic modulus holds a mobile electronic device. A state in which the portable electronic device is held with one hand is shown. In the drawing, the other side is the side on which there are buttons for performing operations and a display for viewing the display screen. The third finger 73 and the fourth finger 74 of the user, which are inserted into the gap between the holding member 21a and the surface of the case 2 of the portable electronic device, are pressed by the force of the holding member 21a trying to recover from the deformation. , the portable electronic device can be stably held with one hand even when the first finger 71 is released.

Although the case of the portable electronic device has been described, the same applies to the case of the housing.

Although it has been explained that the object to be held is a portable electronic device covered with a housing or a portable electronic device further housed in a case, it can be applied to other portable devices and portable objects. This point is the same for all the embodiments described below.

In order to fix the holding member, which is an independent member, to the housing or case, it is fixed later by using adhesive, adhesion, eyelets, etc. Alternatively, as shown in FIG. If the structure is cut out, it can be easily manufactured by a method of integrally molding the holding member and the housing or case using plastic as a material and using a mold.

This embodiment corresponds to the mode 2 described in (Means for Solving the Problems). A holding member is formed by forming a plurality of cutout holes in a surface material forming an outer shape of a housing of a portable electronic device or a case for housing the portable electronic device, and is used to constitute a portable electronic device holder. It is characterized by being

Specifically, by making two parallel cutout holes in the surface material of the housing or case, the remaining portion between the cutout holes is formed as an elastic rectangular holding member. In that respect, the sheet-shaped independent holding member described in Example 1 is created, and it is fixed to the surface of the housing of the portable electronic device or the case for storing the portable electronic device at both ends. is completely different.

The casing of the mobile electronic device or the surface material of the case that stores the mobile electronic device has a cutout hole and a thickness that can be used as a holding member, and the material of the surface material has the necessary elasticity. is the premise. As a method of making a cut-out hole, there are a method of making the cutout after manufacturing the case, a method of manufacturing the case by injection molding of plastic, etc., but an appropriate method may be selected.

FIG. 10 is a perspective view of a case for housing a portable electronic device, with cutouts forming rectangular holding members. The mobile electronic device 5 shown in FIG. 10 is a smartphone or the like, and has a display 50 and the like on the front side in the drawing. The case 2i has a box shape without an upper lid (the front side in the figure), and moves along the dotted line (up in the figure) toward the back of the portable electronic device 5 (the far side in the figure) to place the smartphone. It is a structure of a method to be fitted into the portable electronic device 5 such as.

As shown in FIG. 10, two parallel cutout holes 20i are made in the bottom surface 22i of the case 2i which is designed to cover the back surface of the portable electronic device 5 to be held. It can be used as a holding member 21i having a

In the holding member 21i shown in FIG. 10, the same portion as the fixed portion 213a shown in FIG. 1 is not substantially present. However, considering the portion indicated by the dashed line on the bottom surface 22i of the case 2i at the position where the holding member 21i is virtually extended in the longitudinal direction, this portion can be regarded as the fixing portion of the holding member 21i. This portion is equivalent to the fixing portion of the independent holding member being superimposed on the bottom surface 22i and adhered.

Since this holding member 21i has elasticity and is deformed when a force is applied to the other side in the drawing, a gap is formed between the holding member 21i and the bottom surface 22i in the drawing so that a finger can be inserted into the portable electronic device. 5 can be stably maintained. That is, it functions in the same manner as the holding member 21a fixed to the portable electronic device or the case shown in the first embodiment, and can be used as a portable electronic device holder.

In the case 2i shown in FIG. 10, the holding member 21i can be formed by cutting out the bottom plate 22i as already described, but it is also possible to form the cutout hole from the beginning using a mold.

FIG. 9 is a perspective view of a case in which rectangular holding members are installed. Case 2j shown in FIG. 9 is of the same type as case 2i in FIG. The shape of the case 2j shown in FIG. 9 can also be manufactured integrally with the holding member by using a mold to form the cutout hole 20j as a hole in the same way as the case 2i shown in FIG.
FIG. 9 is the same view as the case where the independent holding member 21j is fixed to the back side (the far side in the figure) of the bottom plate 22j of the case 2j. That is, the independent holding member described in the first embodiment can be manufactured integrally with the case 21 using a mold if it has a shape obtained by cutting out the lower side of the holding member.

In FIGS. 9 and 10, a case for external attachment to a portable electronic device has been described, but as can be seen from the figures, the case is equivalent to the portion obtained by dividing the casing of the portable electronic device itself in half, so it is A similar effect can be obtained by applying this technique to the housing of the device itself. This point is the same for other embodiments.

Although the description has been given of a box type case for storing a portable electronic device such as a smart phone, it can also be applied to a type such as a notebook type that wraps the whole and stores a portable electronic device. This point is the same for other embodiments in which a cutout hole is made in the housing or case to generate the holding member.

Although two side-by-side cutouts are described in this embodiment, other shapes and numbers of cutouts may be used to form non-rectangular retaining members as shown in FIG.

Other points are the same as those of the first embodiment, and the holding member 21i of the present embodiment realizes the same action as the holding member of the portable electronic device as the holding member 21a described in the first embodiment.

In this embodiment, when the elastic modulus of the material of the holding member is large and it is difficult to deform, in order to compensate for this, an expansion part exhibiting a small elastic modulus compared to other parts is arranged in a part of the holding member. It is characterized by A portion of the holding member refers to a portion of the holding member other than the fixed portion.

Specifically, as shown in FIG. 2, an extended portion 211b that has a structure different from that of other portions and has a smaller apparent elastic modulus is arranged in a portion of the holding member 21b in the longitudinal direction.

The material of the holding member is the same as in Example 1, but in this example, a material exhibiting a higher elastic modulus than in Example 1 can also be used. The method of making the holding member 21b is the same as in the first or second embodiment.

FIG. 2 shows an outline view of the holding member of this embodiment. As shown in FIG. 2(a), which is a plan view, the holding member 21b is in the form of a sheet, a rectangle extending in the longitudinal direction (left and right in the figure) and having two separate extensions 211b. there is

As shown in FIG. 2B, which is a side view, fixing portions 213b, which are both ends of the holding member 21b, are adhered to the rear surface (upper side in the figure) of the case 2b of the portable electronic device such as a smartphone to be held. It is fixed by the agent 215b. The back surface is the surface opposite to the side on which the display and the like are arranged.

As can be seen from FIG. 2(a), the extended portion 211b has notches extending in the width direction alternately from both opposing edges in a part of the holding member 21b in the longitudinal direction, excluding the portion of the fixing portion 213b. , resulting in a meandering structure. To avoid complication, all cuts are not numbered. This is the same for the structure using the following notches.

In this structure, when a tensile force is applied to the holding member, each of the numerous cuts causes a small bending deformation and opens the mouth. Each individual bending deformation is small, but as a whole it becomes a large elongation deformation, so the apparent elastic modulus is smaller than the elastic modulus of the material itself.

In the structure formed by making cuts in the extension part of the present embodiment, the places, shapes and numbers of cuts are not necessarily limited to those shown here, and are as shown in FIGS. Various locations, shapes and quantities are acceptable.

For example, FIG. 5(a) shows a holding member 21c with three extended portions 211c, excluding the fixed portion, in the longitudinal direction. In this example, a notch 214c is formed in each extension 211c.
FIG. 5(b) shows an example in which the interval between the notches 214d is widened only at the central portion.
FIG. 5(c) is an example in which the notch 214e is curved rather than linear. If the incision is curved, the deformation distance is long, so even a weak tensile force can increase the deformation. The incisions are not limited to curved lines, and may be polygonal lines.

FIG. 5(d) shows an example in which the notch 214f is inclined with respect to the width direction, and the direction of inclination differs between the left and right with respect to the central portion. When a force is applied to the center flat portion 212f toward the front in the drawing, the flat portion 212f moves to a position (downward in the drawing) deviated from the center line connecting the left and right fixed portions 213f. In this way, by changing the stress when the holding member 21f is deformed to a direction that is not perpendicular to the surface of the portable electronic device or its case, usability can be changed.

FIG. 5 shows a modification of the cut length, direction, bend, and distribution shown in FIG. The deformation of the cut shown in FIG. 2 is not limited to these.

FIG. 6 is a diagram showing an example in which the width of the extension portion is not constant but varies in the longitudinal direction. The contour shape of the extended portion can be freely selected instead of having a fixed width.

Also, the structure of the extension portion may be different from the structure shown in this embodiment. As an example of this, a description will be given of an arrangement in which notches extending in the width direction are arranged in a houndstooth pattern. FIG. 7 is a diagram explaining another example of the structure of the extension part.

FIG. 7(a) reproduces, for comparison, the structure using the notch forming the extension 211b already shown in FIG. Figures 7(b) and 7(c) show cut shapes for alternative structures described herein.

It is a structure in which notches 211m or 211n extending in the width direction are arranged in a houndstooth pattern in the holding member. These cut shapes are different from the meandering shape in which cuts are made alternately as shown in FIG. 7A, and are cut shapes generally used for expanded metal.

7(b) and 7(c) will be described in more detail. The holding member 21m shown in FIG. 7(b) has a vertical row with a cut 214m1 extending in the width direction (up and down in the figure) from the edge and a row with a cut 214m2 only in the central portion that does not overlap the edge. , are arranged alternately (left and right in the drawing), and the cuts 214m1 and 214m2 have a pattern in which the positions of the cuts 214m1 and 214m2 are shifted in the width direction in the vertical direction in the drawing by half the length of the cuts. Note that the reference numerals for the notch 214m1 and the notch 214m2 are not given to all the notches to avoid complication.

Next, the cut 214n of the holding member 21n shown in FIG. 7(c) is a pattern obtained by repeating the pattern of the cut 214m shown in FIG. 7(b) twice vertically in the figure. Since the holding member 21n has more notches in the vertical direction, it can be seen that they are arranged in a houndstooth pattern. Although not shown, a pattern in which the pattern of the notch 214m in FIG. 7B is repeated three times or more and arranged vertically may be used.

FIG. 7(d) shows a state in which, when the holding member 21n shown in FIG. 7(c) is stretched and deformed in the longitudinal direction, the cuts are deformed into rhombuses and rhombus-shaped holes arranged in a houndstooth pattern appear. showing. The use of such a cut shape has the advantage that each deformation when the holding member 21b is stretched is small and the appearance is good.

The structure of the extended portion formed by making cuts is not limited to those explained using FIGS. Alternatively, they can be optimally modified and combined for use according to the materials to be used, for ease of use by the user, or from the viewpoint of design. These are called cut structures.

The actual use of the case with the notched extensions will be described. FIG. 11 is a perspective view of a case in which a retaining member with extensions is installed; Here, as an example, the case 2k is box-shaped without an upper lid. The case 2 is of a type that is moved along the dotted line from the lower side in the drawing and fitted into the portable electronic device 5 for use.

As shown in this figure, a portable electronic device holder using a holding member 21k with an extension 211k is viewed from the opposite side of the state shown in FIG. are the same.

The cut-out hole 20k is used to make it easier to see the holding member 21k on the other side in the drawing, and the holding member 21k is fixed only by the fixing portion 213k at the end, and the other portions are fixed to the case 2k. It is cut out to clearly show that it is not, and it is not absolutely necessary.

Other points are the same as those of the first or second embodiment, and the holder provided with the extension part functions as a portable electronic device holder.
The cut-out retaining member described in Example 2 can be applied with extensions in the same manner as described herein for the separate member in Example 1. FIG.

In this embodiment, a method of providing an extension part using a material having a lower elastic modulus than an extension part using a cut structure in a part of the holding member will be described. FIG. 18 is a plan view of a retaining member with a less elastic material in the extension. It is a holding member in which different materials are arranged in the longitudinal direction and connected by adhesion.

The rectangular holding member 21p shown in FIG. 18(a) has a plurality of independent members, namely, from the left in the drawing, a fixed portion 213p, an extended portion 211p, a flat portion 212p, a second extended portion 211p, and a second fixed portion 213p. Each member is fixed by bonding with an adhesive (not shown). In the side view shown in FIG. 18(b), it can be seen that the ends of the members constituting the holding member are overlapped in the thickness direction and connected.

The two fixing portions 213p of the holding member 21p are fixed to the housing or the case 2 of the portable electronic device 5 with an adhesive 215p to connect the holding member 21p and the case 2 together. The material of the extension part 211p has a smaller elastic modulus than the fixed part 215p and the flat part 212p. A gap is created between them, where a finger can be put, and the portable electronic device can be stably held with one hand.

Replacing a part of the holding member with a material having a different elastic modulus makes it possible, for example, to make the fixed portion and the extended portion similar in thickness compared to a holding member having the same elastic modulus over the entire length. There is an advantage that various types of seals can be applied to the portion where the modulus is large and is not deformed, or the shape of the holding member can be freely selected as will be explained in the next embodiment.

In all the embodiments up to this point, the planar shape of the holding member has been described as a rectangle with a constant width as shown in FIG. It is characterized by its shape. A Y-shape, a substantially triangular shape, and an X-shape will be described below as examples.

FIG. 12 is a plan view of a Y-shaped holding member. This shape is a combination of three rectangles, and the ends of the three rectangles are overlapped at the positions of the flat portions 212, and the overlapped portions are fused and integrated. When viewed as a whole, it has a Y shape.
The Y-shaped retaining member shown in FIG. 12 is a separate member cut from a sheet of material.

In the Y-shaped holding member 21r shown in FIG. 12(a), for example, when viewed from the upper end A to the lower end C in the Y-shaped drawing, the first fixing portion 213r, there is a first flat portion 212r. Then there is a second flat portion 212r3, which merges into one with the first flat portion. Next, the second fixed parts 213r3 are arranged in order. That is, the portion from the end A to the end C forms a holding member as a whole having fixed portions at both ends and a flat portion at the center. This holding member is not linear but has a "<" shape.

Looking from the upper end B to the lower end C in the Y-shaped view likewise forms a holding member. That is, the Y-shaped holding member 21r can be regarded as an assembly of two holding members.

If the elastic modulus of the material is sufficiently small as in the holding member 21r shown in FIG. 12(a), the extension part is not necessary. In the case of the member 21s, an extension 211s can be placed to correct the elastic modulus. In addition, although the shape of the cut forming the extended portion 211s has the same structure as that shown in FIG. 7B, a structure using another cut may be used. This point is the same for the other shapes of this embodiment.

A plurality of (three in this case) end portions of the holding member 21r are fixed portions 213r, 213r2, and 213r3, and adhesives 215r, 215r3, and 215r3 indicated by broken lines in the figure are used to fix the case or the housing of the portable electronic device (not shown). It is glued and fixed to the case. A portable electronic device holder is configured by connecting the holding member 21r and the case. At this time, portions other than the fixing portion 213r of the holding member 21r are not directly fixed to the portable electronic device or its case.

The manufacturing method and material of the holding member 21r are the same as those described in the first embodiment.

FIG. 14(a) is a plan view showing a state in which a Y-shaped holding member 21s having an extended portion is fixed by adhering a fixing portion 213s to the back surface of the case 2s. The position and angle when attaching the holding member to the housing or the case of the portable electronic device for fixing are not limited to those shown in FIG. can be done. It is the same even if it is attached to the housing of the portable electronic device instead of the case. Here, although the holding member 21s having the extended portion has been described, the same applies to the holding member 21r that does not have the extended portion.

A Y-shaped holding member 21r made of a combination of three rectangles shown in FIG. 12A has one end of the rectangular holding member 21a shown in FIG. It can be considered to be equivalent to a shape that is cut halfway in the longitudinal direction and opened to the left and right, and assuming that it is viewed from the side (not shown), the holding member 21b as shown in FIG. 2(c) is viewed from the side, and the holding member 21r functions in the same manner as the holding member 21a shown in FIG.

That is, in FIG. 14(a), a force is applied to the flat portion 212s located between the two fixing portions 213s to deform the flat portion 212s to the front side in the figure, and the lower side of the flat portion 212s and the surface of the case 2s. A gap can be created, and by inserting a finger into the created gap, a portable electronic device such as a smartphone can be stably held with one hand. Although the holding member 21s having the extension portion has been described, the same applies to the holding member 21r having no extension portion.

Furthermore, it is equivalent to two holding members connecting end A to end C and end B to end C, sharing the rectangle forming the Y-shaped lower part (vertical bar). , can be used by inserting a finger from either the left or right side of the figure. In other words, there is an advantage that the portable electronic device holder can be operated with either the left or right hand.

In addition, as compared to the case where the holding member is rectangular and is installed parallel to the longitudinal direction of the portable electronic device, the Y-shaped holding member, as indicated by the oblique dashed line in FIG. A substantial angle of orientation is inclined with respect to the longitudinal direction of a portable electronic device such as a smart phone, which has been found to be more user-friendly.

Regarding the holding member 21s shown in FIG. 12(b), when viewed from one end A to end C of the Y shape, a first fixed portion 213s, a first extended portion 211s, a first The flat portion 212s and the second flat portion are fused to form one flat portion, the second extended portion 211s3, and the second fixed portion 213s3, which differ in that they include the extended portion, but other than that. What has been described so far for the holding member 21r is the same for the holding member 21s.

Next, the case where the holding member has a triangular shape will be described. FIG. 13 is a plan view of a substantially triangular holding member. The generally triangular holding member shown in FIG. 13 is manufactured by cutting out from a sheet of material. The outline of the outside forms a triangle, but since the central part is missing, it is called a substantially triangular shape.

As can be seen from the figure, the shape of the holding member 21 is a combination of three rectangles, more precisely rectangles that are deformed, specifically curved. The two ends of three rectangles are overlapped and fused into one, and when viewed as a whole, they form a substantially triangular shape with the central part removed. In the holding member 21v shown in FIG. 13(a), each of the three rectangles has a fixing portion 213v and a flat portion 212v. For simplicity, only one rectangle is labeled.

FIG. 13(a) shows an example in which the holding member 21v is not provided with an extended portion, and FIG. 13(b) shows an example in which the holding member 21w has a An example in which an extension part 211w is arranged is shown. The extended portion 211w has a structure formed by making a cut, and its shape is the same structure as shown in FIG. 7(b).

In the holding member 21v, three rectangles are combined, and there are three points where their ends are overlapped and fused, which are the vertices of the triangle. A vertex portion of the triangle serves as a fixing portion 213v for fixing the holding member to the housing or case of the portable electronic device.

A dashed line in the drawing indicates an adhesive 215v disposed on the fixing portion 213v for attaching the holding member 21v to a case or the like (not shown). The fixing portion 213v is adhered and fixed to the housing or the case of the portable electronic device with the adhesive 215v. A portable electronic device holder is established by connecting the holding member 21 and the case.

When the holding member 21v is fixed in this manner, portions other than the fixing portion 213v are not directly fixed to the housing or the case of the portable electronic device.

The manufacturing method and material of the holding member 21v are the same as those described in the first embodiment.

FIG. 14(b) is a diagram showing a state in which the substantially triangular holding member 21w is attached to the back surface of the case 2w of the portable electronic device. It is the same even if it is attached to the housing of the portable electronic device instead of the case. The position and angle for fixing the holding member to the portable electronic device or its case are not limited to those shown in FIG.

Looking at any one side of the substantially triangular holding member 21v shown in FIG. 13(a), it is equivalent to the rectangular holding member shown in the first embodiment. That is, a force is applied to the flat portion 212v positioned between the two fixing portions 213v to deform it toward the front side in the drawing, thereby creating a gap between the lower side thereof and the surface of the case (not shown). By inserting a finger into the created gap, a portable electronic device such as a smartphone can be stably held with one hand.

That is, the holding member 21v in the first embodiment functions in the same manner as the rectangular holding member 21a shown in FIG.

Compared to the case where the holding member is rectangular, when the holding member is triangular, the longitudinal angle of the holding member is inclined with respect to the longitudinal direction of the portable electronic device such as a smart phone on two of the three sides. In addition, since the other side can be arranged so as to form a right angle with respect to the longitudinal direction, the user can select various angles for inserting his/her fingers, so there is an advantage that it is easier to use, such as being able to use the left and right hands properly.

Regarding the holding member 21w shown in FIG. 13(b), everything described above is the same as the holding member 21v, except that it has an extension.
In FIG. 14(b), only one of the three rectangles is labeled to indicate the fixed portion, extended portion, and flat portion in order to avoid complication.

Next, a case where the shape of the holding member is X-shaped will be described. FIG. 15 is a plan view of an X-shaped holding member. As can be seen from the figure, the shape of the holding member 21t is a shape obtained by combining four rectangles, and the ends of the rectangles are overlapped and merged into one. When viewed as a whole, it has an X shape.
The X-shaped retaining member shown in FIG. 15 is made by cutting from a sheet of material.

As shown in FIG. 15(a), if the elastic modulus of the material of the holding member 21t is sufficiently small, the extension part is not necessary. If the elastic modulus is large and deformation is difficult, the elastic modulus can be corrected by arranging the extension portion 211u. The extended portion 211u has a structure using cuts, which is similar to that shown in FIG. 7(b). However, it is not limited to this, and other cut structures may be used.

In the holding member 21t shown in FIG. 15(a), for example, looking from one end A, which is a part of the X shape, to the next end C, the first fixing portion 213t, the first flat portion 212t. Then there is a second plateau, which merges into one with the first plateau. Next, the second fixed portions 213t are arranged in order, which as a whole form one holding member having fixed portions at the ends and a flat portion in the center.

In addition to the above, each side of the holding member having the extended portion shown in FIG. 15(b) has the extended portion 211u.

Since there are four combinations of two adjacent rectangles, the X-shaped holding member 21u is apparently an assembly of four holding members. However, each holding member is not linear but has a "<" shape.

In the holding member 21t shown in FIG. 15(a), the ends A, B, C, and D of the four rectangular shapes that are not connected to each other for forming an X shape are connected to the housing of the portable electronic device or the A fixing portion 213t is provided for fixing to the case. A dashed line indicates an adhesive 215t arranged to adhere the fixing portion 213t to the case.

The fixing portion 213t is fixed to the housing or the case of the portable electronic device to be held by the adhesive 215t. The same is true when it is fixed to the housing. A portable electronic device holder is established by connecting the holding member 21t to a housing or a case. At this time, the portion of the holding member 21t other than the fixing portion 213t is not directly fixed to the portable electronic device or its case.

The portion from the end A to the end C of the holding member 21t formed by connecting the four rectangles shown in FIG. It works in the same way, except that there is no The same applies to the portion from the end B to the end D.

That is, a force is applied to the flat portion 212t positioned between the two fixing portions 213t to deform it in the front direction of the figure, thereby creating a gap between the lower side of the flat portion 212t and the surface of the case (not shown). By inserting a finger into the created gap, a portable electronic device such as a smartphone can be stably held with one hand.

The X-shaped holding member 21t can be used by inserting a finger from either the left or right side of the figure. In other words, there is an advantage that the portable electronic device holder can be operated with either the left or right hand.

The manufacturing method and material of the holding member 21t are the same as those described in the first embodiment.
Regarding the holding member 21u shown in FIG. 15(b), everything described above is the same as that of the holding member 21t, except that it has an extended portion.

Next, the V-shaped holding member (not shown) will be described. The V-shape is a shape obtained by combining two rectangles, and is a shape in which the lower ends of two rectangles inclined in opposite directions are overlapped and merged into one. This is the same shape as when the ends of the three Y-shaped rectangles gather and merge into one, moving downward until the vertical bar in the center finally disappears. In simpler terms, it is a shape in which both lower ends of two rectangular holding members are connected.

Two upper ends of two rectangles forming a V shape and three points at the bottom where the two are fused are fixed to the casing of the portable electronic device or its case as a fixing part, and when both are connected, the holder can be attached. Configure.

That is, by applying force to the flat portion positioned between the two fixed portions of one holding member forming the oblique side, the flat portion is deformed to create a gap between the lower side of the flat portion and the surface of the case. A mobile electronic device such as a smart phone can be stably held with one hand by inserting a finger into the created gap. Although not shown, this can be easily guessed from the Y shape.

The method and material for manufacturing the V-shaped holding member are the same as those described in the first embodiment.

Furthermore, shapes other than the V-shape, Y-shape, substantially triangular shape, and X-shape described here can be used as the shape of the holding member. In these glyphs, the rectangles on each side that make up the glyph are also deformed by bending, length, and width. In those cases, a plurality of fixed parts are fixed to the housing or case, and it is only necessary to satisfy the condition that a finger can be inserted into a gap between the fixed parts.

So far, the description has been for a stand-alone retaining member, but now the case for a non-rectangular retaining member formed by a cut-out hole will be described. As examples, cases where the shape of the holding member is Y-shaped, substantially triangular, and X-shaped will be described.

FIG. 16 is a plan view of a holding member manufactured by cutting out unnecessary portions from the case 2. FIG. 16(a) shows a Y-shape, FIG. 16(b) shows a substantially triangular shape, and FIG. 16(c) shows an X-shaped holding member. The state formed on the bottom surface 22x is shown. In FIG. 16 , a virtual fixed portion 213 is indicated by a dashed line. This has already been described in Example 2 and will not be repeated.

In FIG. 16(a), a Y-shaped holding member 20y is formed by cutting out a plurality of (three in this case) V-shaped cutout holes 20y arranged along the Y shape. is shown. FIG. 16(b) shows that a substantially triangular holding member 21z is formed by cutting out three cutout holes 20z and a central cutout hole 20z along the periphery of the substantially triangular shape.

FIG. 16(c) shows that an X-shaped holding member 21x is formed by cutting out four cutout holes 20x along the periphery of the X-shape. In the three figures, the cutout from the surface of the case 2 has a sandy background to distinguish it from the others and make it easier to understand.

16, force is applied to the flat portion 212 of the holding member 21 to deform it, thereby creating a gap between it and the bottom surface 22 of the case 2 or between it and a housing (not shown) existing under the case 2. If the case is opened and a finger is put under it, the case 2 (that is, the portable electronic device (not shown)) can be stably held with one hand. That is, it functions as a portable electronic device holder in the same manner as in the case where the holding member, which is an independent member shown in Example 1 and the like, is fixed to the portable electronic device or the case.

Although the case where the shape of the holding member is Y-shaped, approximately triangular, or X-shaped has been described, as in the case of the independent holding member, other shapes such as a V-shaped, which are a combination of rectangles, can also be used. Good to have. In these glyphs, each side that constitutes the glyph is also deformed by bending, length, and width.

So far, the description has been about retaining members without extensions or retaining members with extensions by means of a notch structure. A case will be described. Shown in FIG. 18(c) is a retention member in the form of a Y-shaped combination of three rectangles with extensions. The extension part is not a structure in which a part of the holding member is cut, but a structure in which a part of the holding member is replaced with a material having less elasticity than the rest. The description of the rectangular holding member 21p shown in FIG. 18(a), which has already been performed in Example 4, is the same, but will be repeated below.

FIG. 18 shows a holding member in which materials having different elastic moduli are arranged in the longitudinal direction of a rectangular shape and connected by adhesion. That is, FIG. 18 is obtained by replacing the cut structure already described in Example 3 with a material having a small elastic modulus.

The Y-shaped holding member 21q shown in the plan view in FIG. 18(c) has a fixed portion 213q, an extended portion 211q, a flat portion 212q, a second extended portion 211q, and a second fixed portion 213q from the left in the drawing. , are composed of independent members, and are connected by bonding with an adhesive (not shown). FIG. 18(d) is a side view of the holding member 21q, and it can be seen that the ends of the members constituting the holding member are overlapped in the thickness direction and connected.

A fixing portion 213q of the holding member 21q is fixed by being adhered to the housing or case of the portable electronic device with an adhesive 215q, and the holding member 21q and the housing or case are connected. The extension part 211q has a smaller elastic modulus than the fixed part 215q and the flat part 212q, and is easily stretched when force is applied to the flat part 212q in FIG. A gap is created between them, where a finger can be put, and the portable electronic device can be stably held with one hand.

The above is a description of a Y-shaped holding member having an extended portion, but the V-shaped, Y-shaped, substantially triangular, and X-shaped members (not shown) also have similar notched structures. The extension can be replaced with an extension made of a material with a lower modulus of elasticity.

Furthermore, regarding a holding member that has a shape other than a rectangle and is equipped with an extension part using a material with a low elastic modulus, it is possible to fix a plurality of points to the housing of a portable electronic device or its case, and deformation that requires an extension part Any shape can be used as the holding member of the portable electronic device holder as long as it is easy to hold.
This completes the description of the retention member with extensions made of low modulus material.

Although the rectangular shape from which each glyph is developed, that is, the shape that extends linearly and extends in a belt-like shape has been described, a curved shape or a shape that has a contour that changes in the width direction may also be used. An example thereof is the substantially triangular shape already described. The substantially triangular holding member is not a straight rectangle, but a combination of three curved rectangles. Another example is to change the contour shape of a rectangle to make it a free shape, such as a bulging shape or a narrow shape as shown in FIG.

(Background Art) When compared with the holding member of a portable electronic device in which the entire length is made of a tape-shaped elastic material and a fixing device is installed at the end portion shown in Patent Document 1, the shape of the holding member is different. In addition to the rectangular shape, it can be freely selected from various shapes such as V-shape, Y-shape, approximately triangular shape, and X-shape. The feature is that it does not get in the way and the structure is simple.

As described above, the shape of the holding member can be a rectangle or a combination of deformed rectangles to form various free shapes as long as the shape does not conflict with the structure and action described above. Furthermore, a free shape may be used instead of a specific character shape.

All the shapes of the tips of the incisions illustrated in the examples so far were linear, but in that case, when force is applied to the holding member and it deforms, the stress concentrates on the tip of the incision and the material breaks. I had a problem with it being easier. This embodiment takes measures against this problem. That is, in order to avoid stress concentration at the tip of the incision, the shape of the tip of the incision is changed from a line to a small circle to solve this problem.

FIG. 17 is an enlarged view of the cut edge. 7(a) and 7(b) have been already shown in FIG. 7(a) and FIG. 7(b). corresponds to FIG. 7(b). FIGS. 17(a) and 17(b) show a method of making the tip 216x of the linear cut substantially circular.

FIG. 17(c) corresponds to FIG. 7(a), and FIG. 17(d) corresponds to FIG. 7(b). FIGS. 17(c) and 17(d) show a technique in which the width of the cut is increased instead of being linear. The plan view shows a method of connecting the end portions of the left and right incisions in the drawing to form a substantially semicircular shape at the incision tip portion 216y.

Both approaches are applicable in all cases as they avoid stress concentrations at the tip when the extension is cut. In the drawing, the diameter of the circle is greatly exaggerated. Also, to avoid clutter, all the cuts and the ends of the cuts are not labeled.

This embodiment is characterized by using a self-adhesive film to fix the holding member to the portable electronic device or its case. FIG. 19 is a diagram showing a state of attachment using a self-adhesive film. Although the rectangular holding member 21b with the extension shown in FIG. 2 is used for illustration, it is applicable to all holding members that are independent members.

As shown in the plan view of FIG. 19(a), the self-adhesive film 8 is oversized with respect to the holding member 21b. The holding member 21b is positioned on the non-adhesive surface of the self-adhesive film 8 (the front side in FIG. 19(a) and the upper side in FIGS. 19(b) and (c)), and the fixing portion 213b is self-adhered by the adhesive 215b. It is adhered to the adhesive film 8. A portion of the holding member 21b other than the fixed portion 213b is not adhered to the self-adhesive film 8. As shown in FIG.

When the protective film on the self-adhesive film 8 (on the other side in FIG. 19(a) and on the lower side in FIGS. 19(b) and (c)) is peeled off, the body of the portable electronic device or its cover can be smoothed. It can easily adhere to the surface and fix the holding member 21b. The adhered self-adhesive film 8 can be peeled off and pasted after being pasted any number of times, and the holding member 21b can be moved to another position or transferred to another device or its cover and fixed. can be done.

The self-adhesive film can be easily peeled off by peeling it from the edge, but it is not easily peeled off even if it is pulled in a direction perpendicular to the surface to which it is attached, so it is suitable for fixing the holding member to the portable electronic device. .

It can be used as a portable electronic device holder capable of stably holding a portable electronic device such as a smart phone or a tablet personal computer with one hand. In addition, it can be widely used as a holder for general electronic equipment or other cases, and as a handle for lifting and holding a wide variety of devices and instruments.

The extended portion is formed by making a cut that penetrates the housing or the case in the thickness direction, and has a smaller elastic modulus than other portions ,
The holding member is in the same plane as the surface of the housing or the case when no force is applied from the outside, and deforms when a force is applied from the outside so that the rear surface of the holding member and the housing are aligned. Forming a gap for inserting a human finger between the lower material or the surface of the housing,
A first transverse line that crosses the arm in the width direction intersects both edges as the starting point of each cut, and extends from one starting point to the other starting point along the first transverse line, The two notches that do not reach the center are collectively referred to as the notch e1,
two incisions separated by a distance d in the longitudinal direction of the arm, located on a second transverse line that does not intersect the first transverse line, and otherwise of the same form, collectively referred to as incision e2;
A third transverse line sandwiched between and not intersecting the first transverse line and the second transverse line extends from the center in the width direction of the arm toward both edges, Let the cut not reaching the edge be the cut c,
A portable electronic device characterized in that the three notches e1, e2, and c are combined into one unit, and a plurality of the units are arranged without gaps, thereby forming the extension part on each of the arms. retainer.
