Description

Technical Field

[0001] The present invention relates to a mobile terminal holder, and particularly to a mobile terminal holder suitable for improving the ease of attachment and detachment of a mobile terminal.

Background Art

[0002] As a mobile terminal holder adopted in a vehicle or the like, those disclosed in Patent Document 1 and Patent Document 2 are known. The mobile terminal holder disclosed in Patent Document 1 is basically composed of a holding portion, an arm portion, and a mounting portion, and is configured to hold a mobile terminal in the holding portion. The holding portion has a back plate that supports the back surface of the mobile terminal and a clamping arm that supports the side surface of the mobile terminal, and elastic protrusions are provided inside the clamping arm.

[0003] In such a mobile terminal holder, by pushing the mobile terminal between the clamping arms, the mobile terminal is held by the elastic force of the elastic protrusions. However, in such a mobile terminal holder, the holding force of the mobile terminal depends on the elastic force of the elastic protrusions. Therefore, when trying to firmly hold the mobile terminal, it is necessary to devise such as making the elastic protrusions have a strong repulsive force, and the force required for attaching and detaching the mobile terminal also becomes large, which may make it difficult to attach and detach.

[0004] The mobile terminal holder disclosed in Patent Document 2 has a main body constituting a back plate, a pair of arms protruding from the side surface of the main body, a pair of sliders, and a holding portion disposed at the lower part of the main body. In such a mobile terminal holder, the paired arms can be opened and closed, and the sliders also expand and contract as the arms open and close.

[0005] According to such a mobile terminal holder, the holding force can be adjusted in the pushed-in state of the arms. On the other hand, for attaching and detaching the mobile terminal holder, operations such as pushing in the arms and pushing in the sliders are required, which hinders smooth attachment and detachment with one action.

[0007] Therefore, the present invention aims to solve the above problems and provide a mobile device holder that can obtain sufficient holding force while maintaining the ease of attaching and detaching the mobile device. [Means for solving the problem]

[0008] To achieve the above objectives, the present invention provides a mobile terminal holder comprising: a base having a support surface with anti-slip measures and supporting the back of a mobile terminal to be held; and arms arranged in pairs on the side of the base, which are capable of rotating in the expanding direction with respect to a base point provided on the base side and are subjected to a biasing force in the closing direction, wherein the inner surface of the pair of arms is provided with an inclined surface that faces the support surface when the mobile terminal is held in place.

[0009] Furthermore, in a mobile terminal holder having the above-described features, the arm is provided with an inclined surface at its tip that is aligned with the expansion direction, and a stopper is provided at the base point to limit the closing angle of the arm. With these features, the arm can be expanded simply by pressing the mobile terminal against the inclined surface.

[0010] Furthermore, in a mobile device holder having the above-described features, it is preferable to provide the base with an adjustment mechanism for adjusting the width of the base point in the arm. Having such features increases the variety of mobile devices that can be held, thereby improving the versatility of the holder.

[0011] Furthermore, in a mobile device holder having the above-described features, one of the pair of arms may be designated as a fixed arm. By having such features, it is possible to reduce the number of movable parts, thereby reducing the number of components and improving strength while achieving similar effects. [Effects of the Invention]

[0012] A mobile device holder having the above-described features makes it possible to obtain sufficient holding power while maintaining the ease of attaching and detaching the mobile device. [Brief explanation of the drawing]

Best Mode for Carrying Out the Invention

[0014] Hereinafter, embodiments of the mobile terminal holder according to the present invention will be described in detail with reference to the drawings. The following embodiments are a part of the preferred embodiments for carrying out the present invention, and as long as the effects are achieved, even if a part of the configuration is changed, it can be regarded as a part of the present invention.

[0015] [Configuration] First, referring to FIGS. 1 to 4, the configuration of the basic form of the mobile terminal holder according to the present invention will be described. In the drawings, FIG. 1 is a perspective view showing a state in which a mobile terminal is held by the mobile terminal holder according to the basic embodiment. FIG. 2 is a perspective view showing the configuration of the mobile terminal holder according to the basic embodiment. FIG. 3 is a plan view showing the configuration of the mobile terminal holder according to the basic embodiment. Further, FIG. 4 is a cross-sectional view for explaining the configuration of the adjustment mechanism.

[0016] The mobile terminal holder 10 according to the present embodiment is basically composed of a base 12 and an arm 18. The base 12 has a support surface 14 provided on the base body 12a and an adjustment mechanism 16. The support surface 14 is provided on one main surface of the base body 12a and is an element for supporting the back surface of the mobile terminal 30 to be held. The support surface 14 according to the present embodiment is provided with anti-slip measures. Specifically, an anti-slip member made of rubber, silicon, or the like that serves as a friction material may be arranged or attached to the support surface 14. As the friction material, in addition to mainly rubber, silicon, etc., resin or the like with a roughened material surface may also be used. Also, the size and planar shape of the base body 12a are not limited, but at least its width should be smaller than the width of the mobile terminal 30 to be held.

[0017] The adjustment mechanism 16 is provided on the back side (the other main surface) of the support surface 14 in the base body 12a, and is an element for moving the rotation base portion 18a1 of the arm 18, which will be described in detail later, in the width direction (the direction indicated by the arrow b). Note that the adjustment mechanism 16 is not limited to a specific configuration as long as it can exhibit its function. In the present embodiment, as shown in FIG. 4, it is configured to exhibit its function by a turnbolt 16a and a socket nut 16b. The turnbolt 16a includes a dial portion 16a1 provided at the center in the longitudinal direction, and bolt portions 16a2 extending from both the one main surface and the other main surface of the dial 16a1. The bolt portion 16a2 is formed to have a smaller diameter than the dial portion 16a1, and is configured to have a right thread and a left thread on the one main surface and the other main surface via the dial portion 16a1.

[0018] The socket nut 16b is configured to include a female screw portion 16b1 (right thread or left thread) that can be screwed with the bolt portion 16a2 extending from each main surface, and a stopper 16b2. The female screw portion 16b1 is arranged so that its rotation is suppressed by a guide groove (not shown) provided in the main body of the adjustment mechanism 16. The stopper 16b2 is provided on the tip side of the socket nut 16b, and the rotation base portion 18a1 of the arm 18 is arranged there. Here, the stopper 16b2 is an element for preventing the arm 18, which will be described in detail later, from reaching a closed state beyond a predetermined range.

[0019] Further, an adjustment limiting portion 16b3 for limiting the adjustment range is provided outside the socket nut 16b. The adjustment limiting portion 16b3 is composed of a long hole 16b3a extending in the adjustment direction and a protrusion 12a1 provided on the base body 12a. The adjustment limiting portion 16b3 having such a configuration serves as a stopper when the protrusion 12a1 contacts the end portion of the long hole 16b3a, and functions as a retaining means for the socket nut 16b.

[0020] With this configuration, rotating the dial portion 16a1 of the turn bolt 16a changes the screwing position between the bolt portion 16a2 and the female thread portion 16b1 of the socket nut 16b, thereby changing the position of the pivot base portion 18a1 of the arm 18. Furthermore, since the bolt portion 16a2 has opposite threads on one main surface and the other main surface via the dial portion 16a1, the movement directions of the two bolt portions 16a2 and the socket nuts 16b that screw into them are reversed, making it possible to widen or narrow the width of the pivot base portion 18a1 of the paired arms 18.

[0021] The arm 18 supports the side of the mobile terminal 30 to be held (by force in the direction indicated by arrow e in Figure 7) and also plays a role in pressing the back of the mobile terminal 30 against the support surface 14 that constitutes the base 12 (by force in the direction indicated by arrow d in Figure 7). The arm 18 has a base portion 18a and a support portion 18b. The base portion 18a is pivotally supported on a part of the stopper 16b2 that constitutes the socket nut 16b so as to be able to rotate freely in the direction indicated by arrow a. Therefore, the connection part with the stopper 16b2 is called the rotating base portion 18a1. The rotating base portion 18a1 is provided with a biasing means that applies a biasing force in the closing direction to the arm 18, although it is not shown. The support portion 18b is provided on the tip side of the base portion and plays a role in supporting the side of the mobile terminal 30 to be held and pressing the back of the mobile terminal 30 against the support surface 14.

[0022] The support portion 18b is formed in a mountain shape. In the arms 18, which are arranged in pairs on both sides of the base 12, the mountain shape constituting the support portion 18b is positioned so that its apex faces opposite to the arms. In the support portion 18b formed in this way, one of the inclined surfaces constituting the mountain shape, 18b1, faces the support surface 14, and the other inclined surface 18b2 faces away from the support surface 14. With this configuration, when the mobile terminal 30 is supported by the arms 18 (see Figure 7), even if the force applied to the contact point between the inclined surface 18b1 and the mobile terminal 30 is in the direction of arrow c, the action of the inclined surface 18b1 generates a force in the direction of arrow d as a component force. As a result, the back of the mobile terminal 30 is pressed against the support surface 14.

[0023] [Effects / Effects] Next, the operation and effects of the mobile terminal holder with the above configuration will be explained with reference to Figures 5 to 7. Note that in Figures 5 to 7, the base 12 constituting the mobile terminal holder 10 is assumed to be fixed or supported by some means.

[0024] Before holding the mobile device 30, the mobile device holder 10 rotates the dial portion 16a1 of the adjustment mechanism 16 to adjust the width of the arm 18 to match the width of the mobile device 30. The width of the arm 18 should be adjusted according to the width and thickness of the mobile device 30, and should be within a range that generates a pressing force on the mobile device 30 against the support surface 14 when the arm 18 is closed and a biasing force is generated.

[0025] First, the operation of holding the mobile terminal 30 in the mobile terminal holder 10 will be explained. After adjusting the width of the arm 18, the mobile terminal 30 to be held is moved in the direction indicated by arrow A and pressed against the inclined surfaces 18b2, 18b2 of the support parts 18b that constitute the pair of arms 18. As a result, slippage occurs between the inclined surfaces 18b2 and the mobile terminal 30, and forces in the direction of arrow d (see Figure 6) and arrow f (see Figure 6) act on the arm 18, causing it to rotate so as to expand with the pivot base 18a1 as the pivot point. As the arm 18 expands, the mobile terminal 30 is pushed toward the base 12, and when the mobile terminal 30 passes over the peak of the mountain shape that constitutes the support part 18b, the arm 18 begins to rotate toward closing.

[0026] When the arm 18 closes with the mobile terminal 30 in contact with the support surface 14, the biasing force of the arm 18 (force in the direction indicated by arrow a in Figure 7) and the angle of the inclined surface 18b1 cause two forces to act on the mobile terminal 30: a supporting force from the width direction (force in the direction indicated by arrow e in Figure 7) and a pressing force against the support surface 14 (force in the direction indicated by arrow d in Figure 7). Since the support surface 14 against which the mobile terminal 30 is pressed is equipped with an anti-slip surface, the mobile terminal 30 pressed against the support surface 14 is held in place without slipping or falling.

[0027] On the other hand, to remove the mobile terminal 30, it is sufficient to grasp the mobile terminal 30 and pull it away from the support surface 14. When the mobile terminal 30 is subjected to such an action, the inclined surface 18b1 pressing the mobile terminal 30 against the support surface 14 slips, causing the arm 18 to expand.

[0028] As the arm 18 expands, the mobile terminal 30 is pulled out, and once the mobile terminal 30 has passed the peak of the mountain-shaped support section, the arm 18 rotates in the closing direction and returns to the restricted position by the stopper 16b2.

[0029] Thus, according to the mobile terminal holder 10 of this embodiment, it is possible to obtain sufficient holding force while maintaining the ease of attaching and detaching the mobile terminal 30.

[0030] [Application Forms] In the above embodiment, it was described that both of the pair of arms 18 rotate in the direction of expanding or closing with the pivot base 18a1 as the pivot point. However, the rotation mechanism of the arms 18 only needs to be provided in at least one of the arms. That is, as shown in Figure 8, one arm 18A may be a fixed arm (not rotating), and only the other arm 18B may be a movable arm (rotating). Even with such a configuration, sufficient holding force can be obtained while maintaining the ease of attaching and detaching the mobile terminal 30, similar to the above embodiment.
