  However, the stand disclosed in Patent Document 1 requires a large storage area based on a flat plate-like stand, and a rear support portion that prevents a rearward fall and a front support portion that prevents a forward fall. This is a configuration that is not suitable for a small electronic device, such as using a large number of mounting parts, such as using the two sets of stand members, and supporting the mounting table in a plane or linear form.

  In addition, the stand disclosed in Patent Document 2 is simple in structure because it is provided with a U-shaped stand so as to be rotatable, but it can prevent tilting backward, but the support angle can be adjusted. Moreover, since it is supported on the mounting table by a surface or a line, a large mounting space is taken. The stand disclosed in Patent Document 3 is based on a flat plate-like stand as in Patent Document 1, requires a large storage area, has many components and lacks smartness in appearance, and the support angle is adjusted in stages. This is a configuration that is not suitable for small electronic devices because it is difficult to make fine adjustments.

  The present invention has been made in view of the above-described circumstances, has a small storage area of the stand, can easily perform fine adjustment of the support angle, requires a small mounting space for the electronic device, and is a portable compact size. The purpose is to provide a simple and attractive support stand suitable for electronic equipment.

  The support stand according to the present invention is a support stand for a desktop / portable small electronic device, one end being held on the back side of the device and the other end being rotatably connected to each other as a support point 2 The support point portion is configured to be capable of being stored in a linear storage groove provided on the back side of the device. One end of the two arms is held in the storage groove, and at least one holding position is variable, or at least one of the two arms is variable in arm length.

  According to the present invention, when the electronic device is used while standing on the mounting table, the inverted arm-like shape that requires two mounting arms can be pulled out of the storage groove to reduce the mounting space. A support stand can be used, and the support angle can be adjusted by changing the holding position and arm length of the two arms. Further, when the stand is not used, the two arms can be linearly stored in the storage groove, and can be stored in a simple state that is convenient for carrying and excellent in handling.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram for explaining the first embodiment, FIG. 1 (A) is a diagram showing a normal use form of the support stand, FIG. 1 (B) is a diagram showing a state in which the support angle is changed, and FIG. FIG. 1C is a diagram illustrating a state in which the support stand is stored, and FIG. 1D is a diagram illustrating a state in which the support stand is viewed from the side. In the figure, 1 is an electronic device, 2 is a device back surface, 3 is a storage groove, 4 is a support stand, 5a and 5b are arms, 6a and 6b are holding portions, and 7 is a support point portion.

  The electronic device 1 applied in the present invention is, for example, a small-sized electronic device suitable for carrying such as a personal computer terminal as a mobile device, a portable AV device, an electronic dictionary, and the like, and is mounted on a mounting table as necessary. It is an electronic device with a desktop function that can also be used. Therefore, when using on a mounting table, the support stand 4 is provided so that a display screen and a speaker part can be easily viewed. On the other hand, a storage groove 3 is provided to fold and store the support stand in order to make it slim with no bulk when transported.

  The support stand 4 is configured by holding one end portions of the two arms 5a and 5b spaced apart from each other on the device back surface 2 and connecting the other end portions to each other so as to be rotatable. On the other hand, the storage groove 3 for storing and holding the support stand 4 is formed in a straight line on the apparatus back surface 2. The two arms 5a and 5b constituting the stand have one end (hereinafter referred to as a holding portion) 6a and 6b held in the storage groove 3, for example, as a left fulcrum L and a right fulcrum R, and the other end (hereinafter referred to as “the holding portion”). (Referred to as “support point part”) 7 are connected to each other so as to be pivotable and serve as a fulcrum F that supports the electronic device 1 on the mounting table. Thereby, the support stand 4 can be made into the stand of the triangle-shaped stable frame which consists of three fulcrum L, R, F as a whole.

  As shown in FIG. 1A, the above-described support stand 4 supports the electronic device 1 at a predetermined angle with the lower side of the electronic device 1 and the support point portion 7 in contact with a mounting table (not shown). . In this case, the lower side of the electronic device 1 is a linear or planar support, but the support stand 4 is a point-like support only at the support point portion 7. For this reason, less space is required on the back side of the device to support the electronic device 1, and the device can be used in a narrow space.

  In the present invention, in the support stand 4 described above, the holding portion 6a or 6b of at least one of the two arms 5a and 5b can be moved, whereby the distance between the fulcrums L and R can be changed. . FIG. 1B shows a state in which the distance between the fulcrums L and R in FIG. 1A is increased. By changing the distance between the fulcrums L and R, the opening angle β between the arms 5a and 5b can be changed. It changes and the distance D from the apparatus back surface 2 of the fulcrum F which is the support point part 7 changes. As a result, the support angle α of the electronic device 1 changes, and the viewing angle from the front of the device can be adjusted.

FIG. 1C shows a state in which the arms 5a and 5b of the support stand 4 are stored in a straight line to facilitate carrying. Since the two arms 5a and 5b are only pivotally connected to each other at the support point portion 7, they are made straight (β = 180 °) by completely opening the holding portions 6a and 6b. Can do. Therefore, the support stand 4 can be stored and held in the linear storage groove 3.
As a result, the area on the back side of the device for storage can be small, and the overall shape can be made smart and refreshing. In addition, it can be easily handled without being caught by protrusions when stored in a portable bag or the like.

  As shown in FIG. 1D, when the support stand 4 is pulled out in the direction perpendicular to the back surface of the device (θ = 90 °), if the height positions of the holding portions 6a and 6b are H, the electronic device The support angle α of 1 is represented by “tan α = D / H”. Here, in order to bring the support angle α close to 90 ° (to bring the electronic device 1 close to vertical support), tan α is made as large as possible. That is, D may be increased and H may be decreased. On the other hand, when the distance between the holding portions 6a and 6b of the support stand 4 is S, the length of the arms 5a and 5b is S / 2 or less.

  Therefore, the distance D of the support point portion 7 from the device back surface 2 is “D <(S / 2)”, and this distance D is determined by the lateral width of the device and cannot be increased too much. On the other hand, by reducing the height position H of the holding portion, the support angle α can be increased (the electronic device 1 is brought closer to the vertical support). However, when the height position H of the holding portion is reduced, the stability is deteriorated. For this reason, in the configuration in which the support stand 4 is pulled out at a right angle from the back of the device, the support angle α cannot be increased so much, and it is desirable that θ <90 °.

  2 and 3 are views showing an example of the support stand described in FIG. 1, in which FIG. 2 is an overall view, and FIGS. 3A and 3B are partial views. In the figure, 8a and 8b are hinge pieces, 9a and 9b are shaft pins, 10 is a sliding piece piece, 11 is a fixed piece, 12 is a guide rail, and other symbols are the same as those used in FIG. The explanation is omitted by using.

  2 and 3, both ends of the arms 5a and 5b of the support stand 4 have hinge pieces 8a and 8b that are rotatably connected, and the hinge piece 8a at one end is supported by a shaft pin 9a. It is attached to the fixed piece 11 of the sliding piece 10 so as to be rotatable, and is the holding portions 6a and 6b described in FIG. The other end of the hinge piece 8b is pivotally connected to the other end of the arms 5a and 5b by a shaft pin 9b. Since this connecting portion is the only fulcrum F in contact with the mounting table of the stand, as described as the support point portion 7, for example, the outer appearance of the mounting table is spherical and elastic rubber-like Cover it with something.

  The sliding piece 10 to which the arms 5a and 5b are attached is provided so as to be slidable along the guide rail 12 inside the storage groove 3 provided on the device back surface 2 side. The sliding piece 10 is arranged so that the sliding position does not move unless a certain amount of force is applied. For example, the sliding piece 10 and the guide rail 12 are coupled to each other with a frictional resistance. In addition, an elastic means may be provided between the sliding piece 10 and the guide rail 12 so as to perform sliding that exhibits an intermittent movement state due to the corrugated uneven surface and the protrusion. .

  As a result, the holding portions 6a and 6b of the arms 5a and 5b are slidable along the storage groove 3 of the device back surface 2, but are prevented from moving and stopped at a predetermined position unless a certain amount of force is applied. Can do. Therefore, the electronic device 1 can be supported by adjusting the distance D to the support point portion 7 on the device back surface 2 and maintaining the distance D unless a predetermined force is applied, and adjusting the electronic device 1 to an arbitrary angle. It can be a possible stand.

  As described with reference to FIG. 1D, the support stand 4 is preferably configured to be pulled out at an angle θ of 90 ° or less with respect to the apparatus back surface 2 as illustrated in FIG. 3B. For this reason, as shown in FIG. 3B, the fixed piece 11 of the sliding piece 10 is provided so as to have a downward inclination, and the hinge piece 8a is inclined and connected so as to be rotatable. The adjustment of the support angle of the support stand 4 changes the distance D with respect to the support point portion 7 of the apparatus back surface 2 by simply changing the interval between the holding portions 6a and 6b (interval between the fulcrums L and R). Can be done. When the support stand 4 is not used, the arms 5a and 5b can be stored in the storage groove 3 formed in a straight line by making them straight.

  FIG. 4 is a diagram for explaining the second embodiment, FIG. 4 (A) is a diagram showing a normal use form of the support stand, FIG. 4 (B) is a diagram showing a state in which the support angle is changed, and FIG. FIG. 4C is a diagram illustrating a state in which the support stand is stored, and FIG. 4D is a diagram illustrating a state in which the support stand is viewed from the side. In the figure, 5c and 5d indicate arms, 6c and 6d indicate holding parts, and the other reference numerals are the same as those used in FIG.

  As in the embodiment of FIG. 1, the support stand 4 holds one end of the two arms 5c and 5d spaced apart from each other on the apparatus back surface 2, and connects the other end to each other so as to be rotatable. Configured. On the other hand, the storage groove 3 for storing and holding the support stand 4 is formed in a straight line on the apparatus back surface 2. The two arms 5c and 5d constituting the stand have one end (hereinafter referred to as a holding portion) 6c and 6d held at both ends of the storage groove 3, for example, as a left fulcrum L and a right fulcrum R, and the other end ( (Hereinafter referred to as “supporting point portion”) 7 are connected to each other so as to be rotatable, and serve as a fulcrum F that supports the electronic device 1 on the mounting table. Thereby, the support stand 4 can be made into the stable stand of the triangular shape which consists of three fulcrum L, R, F as a whole like the example of FIG.

  As shown in FIG. 4A, the support stand 4 described above supports the electronic device 1 at a predetermined angle with the lower side of the electronic device 1 and the support point portion 7 in contact with a mounting table (not shown). . In this case, the lower side of the electronic device 1 is a linear or planar support, but the support stand 4 is a point-like support only at the support point portion 7. For this reason, less space is required on the back side of the device to support the electronic device 1, and the device can be used in a narrow space.

  In the present invention, in the support stand 4 described above, the length of at least one of the two arms 5c and 5d can be adjusted, and thereby the distance between the fulcrum F and the device back surface 2 can be changed. . FIG. 4B shows a state in which the arm lengths of the arms 5c and 5d in FIG. 4A are shortened. By changing the arm lengths of the arms 5c and 5d, the arm 5a and the arm 5b can be changed. The opening angle β changes, and the distance D from the device back surface 2 of the fulcrum F, which is the support point portion 7, changes. As a result, as in the example of FIG. 1, the support angle α of the electronic device 1 changes, the viewing angle on the front surface of the device (not shown) can be adjusted, and the storage property when carried is improved.

  FIG. 4C shows a state in which the arms 5c and 5d of the support stand 4 are housed as the shortest straight line and are easy to carry. Since the two arms 5c and 5d are only pivotally connected to each other at the support point portion 7, they can be made linear (β = 180 °) by shortening the arm length. Therefore, it becomes possible to store and hold the support stand 4 in a straight shape in the straight storage groove 3, and as in the example of FIG. Can be easy to handle.

  As shown in FIG. 4D, when the support stand 4 is pulled out in the direction perpendicular to the rear surface of the device (θ = 90 °), if the height of the holding portions 6c and 6d is H, the electronic device The support angle α of 1 is represented by “tan α = D / H”. Here, in order to bring the support angle α close to 90 ° (to bring the electronic device 1 close to vertical support), tan α is made as large as possible. That is, D may be increased and H may be decreased. Assuming that the number of expansion / contraction steps of the arms 5c and 5d of the support stand 4 is practically about 2 to 3, if the distance between the holding portions 6c and 6d is S, the arm length is (S / 2). × 3 or less.

  Therefore, the distance D of the support point portion 7 from the device back surface 2 is roughly “D <(3S / 2)”, and this distance D is determined by the width of the device and cannot be made too large. On the other hand, by reducing the height position H of the holding portion, the support angle α can be increased (the electronic device 1 is brought closer to the vertical support). However, when the height position H of the holding portion is reduced, the stability is deteriorated. For this reason, in the configuration in which the support stand 4 is pulled out at a right angle from the back of the device, the support angle α cannot be increased so much, and it is desirable that θ <90 °.

  5A and 5B are diagrams showing an example of the support stand described in FIG. 4, in which FIG. 5A is an overall view and FIG. 5B is a partial view. In the drawing, 8c and 8d are hinge pieces, 13 is a mounting piece piece, 14 is a fixed piece, and the other reference numerals are the same as those used in FIGS.

  In FIG. 5, both ends of the arms 5c, 5d of the support stand 4 have hinge pieces 8c, 8d for pivotally connecting, and the hinge piece 8c at one end is attached to the mounting piece by a shaft pin 9a. The holding parts 6c and 6d described with reference to FIG. The other end of the hinge piece 8d is pivotally connected to the other end of the arms 5c and 5d by a shaft pin 9b. Since this connecting portion is the only fulcrum F that is in contact with the mounting surface table of the stand as described as the support point portion 7, for example, the surface of the mounting table is not damaged as in the example of FIG. It is advisable to cover the surface with something like a spherical elastic rubber.

  The mounting piece 13 that holds the arms 5c and 5d is provided inside both ends of the storage groove 3 provided on the device back surface 2 side. For example, the arm lengths of the arms 5c and 5d can be changed using a telescopic structure (or piston rod type). In this case, a frictional resistance is given to the fitting portion so that it does not move unless a certain amount of force is applied to the length adjustment. In addition, the arm length is adjusted by screwing a cylindrical arm having a reverse screw on both ends with a screw rod provided with hinge pieces 8c and 8d on both ends and rotating the cylindrical arm. May be.

  As a result, the arms 5c and 5d can prevent fluctuations in the arm length unless a certain force or more is applied or a rotation operation is performed. Therefore, it is possible to adjust the distance D between the support point portion 7 as the support stand and the device back surface 2, hold the distance D, and adjust and support the electronic device 1 at an arbitrary angle.

  As described with reference to FIG. 4D, the support stand 4 is preferably configured so as to be pulled out at an angle θ of 90 ° or less with respect to the device back surface 2. For this reason, as described with reference to FIGS. 2 to 3, the fixing piece 14 of the mounting piece 13 is provided so as to have a downward inclination, and the hinge piece 8 c is inclined and connected to be rotatable. The support angle of the support stand 4 can be adjusted by a simple operation only by adjusting the lengths of the arms 5c and 5d. When the support stand 4 is not used, the arms 5c and 5b can be stored in the storage groove 3 formed linearly by shortening and folding the arms 5c and 5b.

  Moreover, you may make it comprise with the support stand which combined both embodiment of FIGS. 1-3 mentioned above and embodiment of FIGS. 4-5. In this case, the distance D between the device back surface 2 and the support point portion 7 of the arm can be increased, and the variable range of the support angle can also be increased.
