Advantages of the Invention

[0013] The lighting stand of the present invention has a pedestal portion and a light emitting portion, so that not only can light be irradiated, but also the following specific effects can be achieved.

[0014] According to the lighting stand of the invention according to claim 1, when the first end portion of the smartphone terminal is brought into contact with any one of the convex portion, the concave portion, and the rubber portion of the smartphone holder portion and the second end portion is hung on the outer periphery of the arm base portion, the smartphone terminal is in an appropriate posture for the user, so that the user can work while viewing the screen of the smartphone terminal in a place illuminated by the light source. Furthermore, since the smartphone holder portion is swingable about the vertical axis with respect to the arm base portion on the pedestal portion, the orientation of the smartphone terminal and the smartphone holder portion can be changed to a desired orientation according to the position of the light emitting portion. More specifically, when the light from the light emitting portion hits the smartphone terminal and the reflection of the light emitting portion occurs on the screen of the smartphone terminal, making it difficult to see, changing the orientation of the smartphone holder portion also changes the orientation of the smartphone terminal. Therefore, it is possible to avoid the reflection of the light emitting portion on the screen of the smartphone terminal and easily make the screen of the smartphone terminal easier to see.

[0015] According to the lighting stand of the invention according to claim 2, in addition to the effects achieved by the invention according to claim 1, when the engagement between one end of the smartphone holder portion and the outer periphery of the lower end of the arm base portion is released, it becomes detachable, so that the user can attach and detach it according to the use of the smartphone terminal. Furthermore, when the C-shaped notch of the smartphone holder portion is aligned with a predetermined direction of the arm portion, the arm portion can pass through the C-shaped notch of the smartphone holder portion, so that the user can easily attach and detach the smartphone holder portion. That is, it is not necessary to move the smartphone holder portion up to the light emitting portion for attaching and detaching the smartphone holder portion.

[0016] According to the lighting stand of the invention according to claim 3, in addition to the effects achieved by the invention according to claim 2, when a torsional force acts on the C-shaped portion on one end side of the smartphone holder portion, the vicinity of the slit deforms and the force escapes at the slit portion. Therefore, even when a torsional force acts as an external force, the risk of damage to the C-shaped portion on one end side of the smartphone holder portion can be reduced. Also, when a torsional force acts, the force is released at the slit portion and the C-shaped notch interval widens. Therefore, it is possible to easily release or engage the C-shaped portion on one end side of the smartphone holder portion and the outer periphery of the arm base portion.

[0017] According to the lighting stand of the invention according to claim 4, in addition to the effects achieved by the invention according to claim 1, when setting the smartphone terminal in the smartphone holder part, the difference in posture is smaller compared to a non-tapered configuration whether the orientation of the smartphone terminal is horizontal or vertical. Therefore, the usability of the smartphone holder part can be improved for the user. Furthermore, when lifting the smartphone holder part upward, the engagement between one end side of the smartphone holder part and the tapered outer periphery of the arm base part is released, so that the attachment and detachment of the smartphone holder part can be easily performed.

[0018] According to the lighting stand of the invention according to claim 5, in addition to the effects achieved by the invention according to claim 4, the irradiation direction of the light emitting part can be freely adjusted by the swinging of six swinging joint parts including the arm base part. Therefore, in the user's work, for example, not only the screen of the personal computer but also the screen of the smartphone terminal can be illuminated to facilitate the work. Also, since the tapered shape of the arm base part appeals to the user that the arm base part can rotate freely about the vertical axis with respect to the pedestal part, the user can intuitively understand that the arm base part can rotate freely about the vertical axis with respect to the seat part, and it is possible to easily operate the arm base part and the arm part. Furthermore, since the light emitting part can move freely and it is easy for the reflection of the light emitting part to occur on the screen of the smartphone terminal, a configuration in which the orientation of the smartphone terminal and the smartphone holder part can be changed to a desired orientation according to the movement of the light emitting part is particularly effective.

[0019] According to the lighting stand of the invention according to claim 6, in addition to the effects achieved by the invention according to any one of claims 1 to 5, the length from the portion engaging with the lower end outer periphery of the arm base part in the smartphone holder part to the portion contacting the smartphone terminal can be freely changed. Therefore, the length of the smartphone holder part can be changed according to the size of the smartphone terminal, and the inclination and posture of the smartphone terminal can be easily adjusted.

[0020] According to the lighting stand of the invention according to claim 7, any one of claims 1 to 5 is used, so that the contact point with the smartphone terminal can be freely changed. Therefore, according to the size of the smartphone terminal, the contact point with the smartphone terminal in the smartphone holder part can be changed to easily adjust the inclination and posture of the smartphone terminal.

In addition, in FIG. 4, illustration of the arm portion 130 and the light emitting portion 140 is omitted so as to facilitate understanding of the present invention.

[0025] As shown in FIGS. 1 to 4, a lighting stand 100 according to an embodiment of the present invention includes a pedestal portion 110, an arm base portion 120, an arm portion 130, a light emitting portion 140, and a smartphone holder portion 150. Among these, the pedestal portion 110 is provided so as to be placed on a flat place. Further, the arm base portion 120 is provided above the pedestal portion 110. As an example, the arm base portion 120 extends upward from the pedestal portion 110 so as to be rotatable about the vertical direction with respect to the pedestal portion 110. Furthermore, the arm portion 130 is connected to the arm base portion 120. As an example, the arm portion 130 is swingably connected to the arm base portion 120.

[0026] In addition, the light emitting portion 140 is provided at the tip side of the arm portion 130 and has a light source. Furthermore, the smartphone holder portion 150 is installed on the upper surface of the pedestal portion 110. At the same time, one end side 151 of the smartphone holder portion 150 is formed in a shape that contacts the outer periphery 121 of the lower end of the arm base portion 120 and is swingably engaged with the arm base portion 120 as an axis. As an example, as shown in FIG. 3(A), one end side 151 of the smartphone holder portion 150 is formed in a shape including a C-shaped 151a.

[0027] In addition, the other end side 152 of the smartphone holder portion 150 is formed in a shape having at least one of a convex portion 152b protruding upward from a flat portion 152a and a concave portion recessed downward, or having a rubber portion. In the present embodiment, as an example, the other end side 152 of the smartphone holder portion 150 is formed in a shape having a convex portion 152b protruding upward from a flat portion 152a. One first end portion SP1 of the smartphone terminal SP is in contact with at least one of the convex portion 152b, the concave portion, and the convex portion 152b as a rubber portion, and the second end portion SP2 on the side opposite to the first end portion SP1 of the smartphone terminal SP is provided with a smartphone holder portion 150 in a contactable relationship with the outer periphery 122 of the arm base portion 120.

[0028] Note that by making it a concave portion instead of the convex portion 152b, the first end portion SP1 of the smartphone terminal SP comes into contact with the concave portion, and the first end portion SP1 of the smartphone terminal SP is supported by the concave portion. Further, by forming the other end side 152 of the smartphone holder portion 150 to have a rubber portion instead of the convex portion 152b, the first end portion SP1 of the smartphone terminal SP comes into contact with the rubber portion, and a frictional force is generated between the smartphone terminal SP and the rubber portion due to the weight of the smartphone terminal SP, and the rubber portion functions as an anti-slip and supports the first end portion SP1 of the smartphone terminal SP.

[0029] Thereby, as shown in FIG. 1, when the first end portion SP1 of the smartphone terminal SP is brought into contact with any one of the convex portion 152b, the concave portion, and the rubber portion of the smartphone holder portion 150 and the second end portion SP2 is placed on the outer periphery 122 of the arm base portion 120, the smartphone terminal SP assumes an appropriate posture for the user. As a result, the user can work while viewing the screen of the smartphone terminal SP in a place illuminated by the light source. Furthermore, as shown in FIG. 4, the smartphone holder portion 150 is swingable about a vertical axis with respect to the arm base portion 120 on the pedestal portion 110. As a result, the orientations of the smartphone terminal SP and the smartphone holder portion 150 can be changed to a desired orientation according to the position of the light emitting portion 140. More specifically, when the light from the light emitting unit 140 hits the smartphone terminal SP and the reflection of the light emitting unit 140 occurs on the screen of the smartphone terminal SP, making it difficult to see, changing the orientation of the smartphone holder unit 150 also changes the orientation of the smartphone terminal SP. As a result, it is possible to avoid the reflection of the light emitting unit 140 on the screen of the smartphone terminal SP and easily make the screen of the smartphone terminal SP easier to see.

[0030] Furthermore, in this embodiment, as shown in FIG. 3(A), one end side 151 of the smartphone holder unit 150 is formed in a shape including a C-shaped 151a that engages with the outer periphery 121 of the lower end of the arm base unit 120. And, as shown in FIGS. 2 and 3(A), the notch interval D1 of the C-shape at one end side 151 of the C-shaped 151a is configured to be longer than the dimension D2 of the thickness of the arm unit 130 in a predetermined direction.

[0031] Thereby, when the engagement between one end of the smartphone holder unit 150 and the outer periphery 121 of the lower end of the arm base unit 120 is released, it becomes detachable. As a result, the user can attach and detach according to the use or non-use of the smartphone terminal SP. Furthermore, when the C-shaped notch of the smartphone holder unit 150 is aligned with the predetermined direction of the arm unit 130, the arm unit 130 can pass through the C-shaped notch of the smartphone holder unit 150. As a result, the user can easily attach and detach the smartphone holder unit 150. That is, it is not necessary to move the smartphone holder unit 150 up to the light emitting unit 140 for attaching and detaching the smartphone holder unit 150.

[0032] Also, in this embodiment, as shown in FIG. 3(A), in the smartphone holder unit 150, a slit 151b is provided at a position opposite to the C-shaped notch position. As a result, when a torsional force acts on the C-shaped portion 151a on one end side 151 of the smartphone holder portion 150, the vicinity of the slit 151b deforms and the force escapes at the location of the slit 151b. Consequently, even when a torsional force acts as some external force, the risk that the C-shaped portion 151a on one end side 151 of the smartphone holder portion 150 will be damaged can be reduced. Also, when a torsional force acts, the force is released at the location of the slit 151b, and the notch interval D1 of the C-shape widens. As a result, the engagement between the C-shaped portion 151a on one end side 151 of the smartphone holder portion 150 and the outer periphery 122 of the arm base portion 120 can be easily released or engaged.

[0033] Furthermore, in the present embodiment, as shown in FIGS. 1 and 2, the outer periphery 122 of the arm base portion 120 is formed in a tapered shape that gradually decreases upward in the vertical direction. Thereby, when setting the smartphone terminal SP in the smartphone holder portion 150, regardless of whether the smartphone terminal SP is placed horizontally or vertically, the difference in posture is smaller compared to a configuration that is not tapered. As a result, the usability of the smartphone holder portion 150 for the user can be improved. Furthermore, when the smartphone holder portion 150 is lifted upward, the engagement between one end side 151 of the smartphone holder portion 150 and the tapered outer periphery 122 of the arm base portion 120 is released. As a result, the attachment and detachment of the smartphone holder portion 150 can be easily performed.

[0034] Also, in the present embodiment, as shown in FIG. 5(A), the arm base portion 120 is provided so as to be rotatable about the vertical axis with respect to the pedestal portion 110. Then, when the user rotates the arm base portion 120 about the vertical axis with respect to the pedestal portion 110, the light emitting portion 140 moves greatly in the left-right direction when viewed from above. Furthermore, as shown in FIGS. 5(B) to 7(B), between the arm base portion 120 and the light emitting portion 140, the arm portion 130 has five swing joint portions. More specifically, the arm portion 130 has, as swing joint portions, a first joint portion 131, a second joint portion 132, a third joint portion 133, a fourth joint portion 134, and a fifth joint portion 135.

[0035] As shown in FIG. 5(B), when the user moves the first joint portion 131 of the arm portion 130, the light emitting portion 140 moves greatly in the vertical direction when viewed from the side. Also, as shown in FIG. 6(A), when the user moves the second joint portion 132 of the arm portion 130, the light emitting portion 140 moves moderately in the vertical direction when viewed from the side. Furthermore, as shown in FIG. 6(B), when the user moves the third joint portion 133 of the arm portion 130, the light emitting portion 140 moves slightly in the vertical direction as if shaking the head when viewed from the side. Also, as shown in FIG. 7(A), when the user moves the fourth joint portion 134 of the arm portion 130, the light emitting portion 140 rolls when viewed from the front. Furthermore, as shown in FIG. 7(B), when the user moves the fifth joint portion 135 of the arm portion 130, the light emitting portion 140 moves slightly in the lateral direction as if shaking the head when viewed from above.

[0036] As a result, the irradiation direction of the light emitting portion 140 becomes free by the swinging of six swing joint portions including the arm base portion 120. As a result, in the user's work, for example, it is possible to irradiate light not only on the screen of the personal computer but also on the screen of the smartphone terminal SP to facilitate the work. Also, the tapered shape of the arm base portion 120 appeals to the user that the arm base portion 120 is rotatable about the vertical axis with respect to the pedestal portion 110. As a result, the user can intuitively understand that the arm base portion 120 is rotatable about the vertical axis with respect to the seat portion, and can easily operate the arm base portion 120 and the arm portion 130. Furthermore, the light-emitting unit 140 can move freely, and it is likely that the light-emitting unit 140 will be reflected on the screen of the smartphone terminal SP. As a result, a configuration in which the orientations of the smartphone terminal SP and the smartphone holder unit 150 can be changed to a desired orientation according to the movement of the light-emitting unit 140 is particularly effective.

[0037] Although an example in which one end side 151 of the smartphone holder unit 150 has a C-shaped 151a has been described, the present invention is not limited to this. For example, as shown in FIG. 8(A), one end side 151 of the smartphone holder unit 150 may have a substantially "O" shape and may have a notch. Also, as shown in FIG. 8(B), one end side 151 of the smartphone holder unit 150 may have a complete "O" shape. Furthermore, as shown in FIG. 8(B), the arm base portion 120 may be a quadrangular prism, and the outer periphery 122 of the arm base portion 120 may be angular. That is, regarding the shape of one end side 151 of the smartphone holder unit 150, it is sufficient that it is in contact with the outer periphery 122 of the arm base portion 120 and is swingably engaged.

[0038] For example, when the arm base portion 120 is a cylinder and the outer periphery 122 of the arm base portion 120 is a constant curved surface, the shape of one end side 151 of the smartphone holder unit 150 may be a shape having a triangle to a polygon on the inside. Also, as shown in FIG. 8(B), it may be formed with the same width from one end side 151 to the other end side 152 of the smartphone holder unit 150.

[0039] Furthermore, as shown in FIG. 8(C), it may be formed so as to be wider from one end side 151 to the other end side 152 of the smartphone holder unit 150. Further, the smartphone holder portion 150 may be formed of a flexible plastic resin, and a C-shaped 151a portion on one end side 151 of the smartphone holder portion 150 may be configured to snap fit swingably with respect to the outer periphery 122 of the columnar arm base portion 120.

[0040] Furthermore, although the configuration in which one convex portion 152b is provided on the other end side 152 of the smartphone holder portion 150 has been described, the present invention is not limited to this. For example, as shown in FIG. 9(A), a plurality of convex portions 152b, which are examples of convex portions or concave portions of the smartphone holder portion 150, may be provided in the direction connecting the one end side 151 and the other end side 152. Thereby, the contact location with the smartphone terminal SP can be freely changed. As a result, according to the size of the smartphone terminal SP, the contact location with the smartphone terminal SP in the smartphone holder portion 150 can be changed, and the inclination and posture of the smartphone terminal SP can be easily adjusted. Also, it is possible to use a tablet terminal instead of the smartphone terminal SP.

[0041] Also, as shown in FIGS. 9(B) and 9(C), the smartphone holder portion 150 may be configured to be adjustable in length in the direction connecting the one end side 151 and the other end side 152. More specifically, the smartphone holder portion 150 has a first member 151c including the one end side 151 and a second member 152c including the other end side 152. Furthermore, at least one of the first member 151c and the second member 152c has a multi-stage concavo-convex structure 151d (152d) in the direction connecting the one end side 151 and the other end side 152 and can be engaged with the other. In the present embodiment, as an example, both the first member 151c has a multi-stage concavo-convex structure 151d and the second member 152c has a multi-stage concavo-convex structure 152d.

[0042] And, by changing the engagement portions of the plurality of stepped uneven structures 151d and 152d, the length of the smartphone holder portion 150 is configured to be changed. As a result, the length from the portion that engages with the outer periphery 121 at the lower end of the arm base portion 120 in the smartphone holder portion 150 to the portion that contacts the smartphone terminal SP can be freely changed. As a result, the length of the smartphone holder portion 150 can be changed according to the size of the smartphone terminal SP, and the inclination and posture of the smartphone terminal SP can be easily adjusted.

[0043] The lighting stand 100, which is an embodiment of the present invention thus obtained, includes a pedestal portion 110 placed on a flat place, an arm base portion 120 provided above the pedestal portion 110, an arm portion 130 connected to the arm base portion 120, a light emitting portion 140 provided at the tip side of the arm portion 130 and having a light source, and a smartphone holder portion 150 that is installed on the upper surface of the pedestal portion 110 and is formed in a shape in which one end side 151 contacts the outer periphery 121 at the lower end of the arm base portion 120 and is swingably engaged, and the other end side 152 has at least one of a convex portion 152b protruding upward from a flat portion 152a and a concave portion recessed downward, or is formed with a rubber portion, and one first end portion SP1 of the smartphone terminal SP can be in contact with at least one of the convex portion 152b, the concave portion, and the rubber portion, and the second end portion SP2 on the side opposite to the first end portion SP1 of the smartphone terminal SP can be in contact with the outer periphery 122 of the arm base portion 120. By having this structure, the user can work while viewing the screen of the smartphone terminal SP in a place illuminated by the light source, and can change the orientations of the smartphone terminal SP and the smartphone holder portion 150 to a desired orientation according to the position of the light emitting portion 140, and can avoid the reflection of the light emitting portion 140 on the screen of the smartphone terminal SP and easily make the screen of the smartphone terminal SP easier to view.

[0044] Furthermore, one end side 151 of the smartphone holder part 150 is formed in a C-shaped 151a that engages with the outer periphery 121 of the lower end of the arm base part 120. The notch interval D1 of the C-shape at one end side 151 of the C-shaped 151a is longer than the dimension D2 of the thickness of the arm part 130 in a predetermined direction. Thus, the user can attach and detach the smartphone holder part 150 according to the use of the smartphone terminal SP, and there is no need to move the smartphone holder part 150 to the light emitting part 140 for the attachment and detachment of the smartphone holder part 150. The user can easily attach and detach the smartphone holder part 150.

[0045] Also, in the smartphone holder part 150, a slit 151b is provided at a position opposite to the notch position of the C-shape. Even when a torsional force acts as some external force, the risk of the C-shaped 151a of one end side 151 of the smartphone holder part 150 being damaged can be reduced, and the engagement between the C-shaped 151a of one end side 151 of the smartphone holder part 150 and the outer periphery 122 of the arm base part 120 can be easily released or engaged.

[0046] Furthermore, the outer periphery 122 of the arm base part 120 is formed in a tapered shape that gradually becomes smaller upward in the vertical direction. This can improve the usability of the smartphone holder part 150 for the user and enable the user to easily attach and detach the smartphone holder part 150.

[0047] Further, the arm base portion 120 is provided so as to be rotatable about the vertical direction with respect to the pedestal portion 110. Between the arm base portion 120 and the light emitting portion 140, the arm portion 130 has five swing joint portions, namely, a first joint portion 131, a second joint portion 132, a third joint portion 133, a fourth joint portion 134, and a fifth joint portion 135. Thus, in the work of the user, for example, not only the screen of a personal computer but also the screen of the smartphone terminal SP can be illuminated to facilitate the work. The user can intuitively understand that the arm base portion 120 is rotatable about the vertical direction with respect to the seat portion, and can easily operate the arm base portion 120 and the arm portion 130. A configuration in which the directions of the smartphone terminal SP and the smartphone holder portion 150 can be changed to a desired direction in accordance with the movement of the light emitting portion 140 is particularly effective.

[0048] Furthermore, the smartphone holder portion 150 has a first member 151c including one end side 151 and a second member 152c including the other end side 152. At least one of the first member 151c and the second member 152c has a multi-stage concavo-convex structure 151d (152d) in the direction connecting the one end side 151 and the other end side 152 and is engageable with the other. By changing the engagement position of the multi-stage concavo-convex structures 151d and 152d, the length of the smartphone holder portion 150 is changed. Accordingly, the length of the smartphone holder portion 150 can be changed according to the size of the smartphone terminal SP, and the inclination and posture of the smartphone terminal SP can be easily adjusted.

[0049] In addition, since a plurality of convex portions 152b or concave portions of the smartphone holder portion 150 are provided in the direction connecting the one end side 151 and the other end side 152, the position where the smartphone terminal SP contacts the smartphone holder portion 150 can be changed according to the size of the smartphone terminal SP, and the inclination and posture of the smartphone terminal SP can be easily adjusted. The effect is very great.
