Description

  The present invention relates to a strap for a mobile terminal, and more particularly to a strap structure suitable for use in a mobile phone.

  A mobile phone strap will be described with reference to FIGS. As shown in FIG. 6, the strap 1 is generally attached to the mobile phone body using a small mooring hole 91 provided on the side surface of the casing of the mobile phone 9 so that the mobile phone falls when it is carried. It is used to prevent the mobile phone from being taken out or to easily take out the mobile phone from a storage part such as a pocket or a bag (see Patent Document 1).

  As shown in FIG. 7, the strap 1 includes a string portion 11 for grasping by hand, a root portion 12 for binding to the housing through a mooring hole 91 of the housing of the mobile phone 9, and the strap portion 11 and the root portion. 12 and a fastener 13 for connecting the two.

  It is also widely used to attach various ornaments such as so-called characters and accessories to such mobile phone straps according to user's preference. Some of the characters and accessories attached to the strap are designed to swing by electromagnetic waves when an incoming call is received by the mobile phone (see Patent Document 2), and a strap with an earphone has also been proposed (patent) Reference 3), and added value to the strap.

  Furthermore, there is a configuration in which a mobile phone is prevented from falling out of a pocket by attaching a clip to the tip of the strap string and fixing the clip to clothes or the like (see Patent Document 4).

JP 2003-11611 A JP 2000-236371 A JP 2001-326712 A JP-A-8-274852 Japanese Patent Laid-Open No. 10-288545

  As described above, the mobile phone strap has been changed to a structure having various value-added functions in addition to the original function of preventing fall, but a strap having the function of a scale does not yet exist. . For example, since the postage varies depending on its weight, it is important to know the weight of each postal item when handling a large amount of postal items. Therefore, if a strap attached to a mobile phone that is always carried is provided with a function of a weigh scale to increase added value, the weight scale will not be carried and the bulk in the pocket or bag will be reduced. You can also weigh immediately when you need it without having to look for a scale.

  Here, referring to Patent Document 5, a technique in which a strap is attached to a weighing scale is proposed. However, this technique is merely an improvement in the carrying ability of the weighing scale. It did not provide added value functions by providing a total function.

  The objective of this invention is providing the strap for portable terminals which added the function of the weigh scale and improved the added value function.

  Another object of the present invention is to provide a strap for a portable terminal that can reduce the bulk in a pocket or bag without having to carry a scale.

  Still another object of the present invention is to provide a strap for a portable terminal that can prevent a weight scale from being dropped, lost, or misplaced.

  The strap according to the present invention is a strap for a portable terminal in which a string portion and a root portion are connected by a fastener, and a weight scale is provided on the fastener. And the pinching member which clamps a to-be-measured object was connected to the said string part, It is characterized by the above-mentioned.

  Further, the weight scale has a spring balance structure or a piezoelectric element, and when the piezoelectric element is used, an electronic circuit that digitally processes an output signal of the piezoelectric element; It further has a display means for displaying the digital processing output, and further has an operation section for performing a processing operation on the electronic circuit.

  ADVANTAGE OF THE INVENTION According to this invention, there exists an effect that an added value can be raised to a strap by embedding a weight scale in the fastener which connects the string and netsuke of the strap for portable terminals. In addition, according to the present invention, since the weight scale is added to the strap for the portable terminal, the weight of the object can be weighed anytime and anywhere, such as on the move, and it is not necessary to carry the weight scale. There is also an effect that can be reduced.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an embodiment of the present invention, and is an overall configuration diagram including a partially enlarged sectional view. 1, the same parts as those in FIGS. 6 and 7 are denoted by the same reference numerals.

  Referring to FIG. 1, the strap 1 according to the present embodiment is passed through a string portion 11 for grasping by hand and a mooring hole (refer to 91 in FIG. 6) provided on a side surface of a casing of a mobile phone (not shown). It has a netting portion 12 for linking to the housing, and a spring scale portion 21 serving as a substitute for a fastener (see 13 in FIG. 7) for connecting the string portion 11 and the netting portion 12.

  The netting portion 12 is attached to the upper surface of the cylindrical cover 23 of the spring balance 21. For example, the netting portion 12 is bonded to the inner surface of the cover 23 with a synthetic resin through a small through hole provided in the upper surface of the cover 23. Similarly, the string portion 11 is also affixed with a synthetic resin on the inner surface of the scale cylinder 24 through a small through hole provided in the bottom surface of the scale cylinder 24 of the spring balance 21.

  The cylindrical cover 23 and the scale cylinder 24 of the spring balance 21 are connected to each other by a coil spring 27, and the upper end portion of the coil spring 27 is attached to the inside of the cover 23, and the lower end portion of the coil spring 27. The part is attached to the inside of the scale cylinder 24. The scale cylinder 24 is fitted in the cylinder cover 23, and the scale cylinder 24 performs a piston motion in the cylinder cover 23 according to the expansion and contraction of the coil spring 27.

  By doing so, when weight is applied to the string portion 11, the scale cylinder 24 is pulled downward and the coil spring 27 extends. Accordingly, the value corresponding to the weight can be determined by the scale drawn on the outer periphery of the scale cylinder 24.

  In order to measure the weight of the object, for example, a hook clip 26 is connected to the string portion 11 by a metal ring 25. Referring to FIG. 2, the details of the connection mode between the string portion 11 and the hook clip 26 are shown. By passing the ring 25 through the string portion 11 and passing the ring 25 through the hole of the handle portion of the hook clip 26. The string part 11 and the hook clip 26 are connected. In FIG. 1, a postal item is shown as an object to be weighed.

  When weighing an object, the object is clamped with the mouth clip 26, and when not weighed, a plastic or silicone soft cover is fitted to the mouth clip 26 so that the strap can be inserted into a pocket or bag. Even if it is inserted, it does not get entangled with other objects, and the cellular phone can be pulled out by taking the string portion 11 of the strap 1.

  In addition, in order to prevent looseness of the coil spring 27 and deterioration of measurement accuracy caused by the loosening, when the spring balance 21 is not used, the scale cylinder 24 does not come out of the cylindrical cover 23 even if force is applied. A stopper mechanism for fixing the scale cylinder 24 is provided. This stopper mechanism can use a commercially available and simple mechanism, and therefore, details are not disclosed in the drawings and description, and only an outline is described.

  For example, a thin small groove 28 is provided on the outer peripheral surface of the lower end of the scale cylinder 24, and a stopper slide switch 29 is provided on the outer peripheral part of the cylindrical cover 23. When the scale cylinder 24 is fixed to the cover 23, the scale cylinder 24 is pushed into the cover 23, the slide switch 29 is moved to a lower position indicated by a dotted line, and then the switch 29 is pushed inward of the cover 23. Thus, the sharp tip of the switch 29 is anchored in the groove 28, and the spring balance can be fixed. In order to release this fixation, the reverse operation may be performed.

  FIG. 3 is a diagram showing the whole of another embodiment of the present invention, and the same parts as those in FIG. 1 are denoted by the same reference numerals. Also in this example, the fastener 33 to which the string part 11 and the root part 12 are connected is a fastener with a weighing scale. The fastener 33 incorporates a pressure sensor that measures the weight of the object to be measured that is clamped by the hook clip 26 at the tip of the string portion 11. The weight is electronically measured by the pressure sensor and displayed on the display unit 34.

  The display unit 34 is generally a small liquid crystal screen or a display screen such as characters and numbers configured by LEDs. In addition, an operation button 37 is provided in the vicinity of the display unit 34, and is used for performing weight measurement, and for setting and adjusting weight measurement and display.

  When the object to be measured is clamped by the heel clip 26, gravity is applied to the gravity transmission member 41 by the string attachment member 45 below the fastener 33 with the weighing scale via the string portion 11 as shown in FIG. become. This gravity is transmitted to the cylindrical part at the lower part of the gravity transmission member 41, and the pressure sensor part 43 mounted on the base part 44 is moved downward while pulling the umbrella-shaped part at the upper part of the gravity transmission member 41 downward. Will be crushed. That is, the gravity transmission member 41 has a function of converting gravity into pressure. Accordingly, a pressure corresponding to the weight applied to the string portion 11 is applied to the pressure sensor unit 43, and a current corresponding to the pressure is output from the pressure sensor unit 43.

  Here, referring to FIG. 5, the weight-attached fastener 33 incorporates a digital electronic circuit for setting weight measurement data, measurement operation, and the like. It functions as a control unit, and has an IC for performing control processing and arithmetic processing, such as a CPU 51. In order to keep the cost and size as small as possible, the peripheral device interface and the driver circuit for driving the peripheral device are built in the microcomputer 51.

  As shown in FIG. 5, a microcomputer 51, an operation button 37, a pressure sensor unit 43, a display unit 34, and a battery 52 for supplying power are provided. The battery 52 is a low-cost commercially available standard. Such a small button-type battery is preferable, and a structure embedded in the back surface of the display unit 34 is preferable. The lid covering the battery can be freely opened and closed to facilitate battery replacement. Although all the peripheral devices can be directly supplied with power from the battery 52, the battery 52 is only connected to the microcomputer 51, and the microcomputer 51 adjusts and supplies the necessary power to the peripheral device. This has the advantage that a power supply wiring system for peripheral devices is not necessary.

  The microcomputer 51 includes a plurality of operation buttons 37 having contacts with the user, a pressure sensor unit 43 that supplies a current corresponding to the weight of the object to be measured to the microcomputer 51, a value obtained by converting the weight of the object to be measured into a number, It is connected to a display unit 34 that displays other control information.

  The user can notify the microcomputer 51 of the request using the plurality of operation buttons 37. Further, in order to select or confirm the request, the microcomputer 51 displays information for that purpose on the display unit 34. The plurality of operation buttons 37, for example, issue a weight measurement request, calibrate the current value of the pressure sensor unit 43, or terminate the measurement function and turn off the power to the pressure sensor unit 43. . In addition, in a state where the power supply to the pressure sensor unit 43 is cut off, for example, information such as time can be displayed on the display unit 34, and the time can be adjusted by the operation button 37.

  As described above, the pressure sensor unit 43 supplies the microcomputer 51 with a current corresponding to the weight of the object to be measured or the gravity that causes it. The microcomputer 51 converts the current value into a number representing a weight value with reference to, for example, a pre-stored data table. This number is converted into a signal, sent to the display unit 34, and the display unit 34 displays the weight.

  In each of the above-described embodiments, the strap for a mobile phone has been described. However, the present invention is not limited to this, and it is obvious that the strap can be widely applied to a strap of a mobile communication terminal or a mobile information processing terminal.
