JP2006311976A - Balance incorporated handle of bag - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To attain a subject of incorporating an inexpensive and simple structure balance to a handle without impairing the function of the handle so as to be able to measure the weight of a bag by raising up the handle of the bag. <P>SOLUTION: The incorporated balance calculates the weight from the sum of forces acting on two positions because the handle is usually secured to at the two positions. Two wires are constituted so that each extension mark point reversely move and a main scale and a sub scale are secured to the extension mark points because the extension of the two wires secured to the stretchable handle is read out by summing them. The relative moving distance of the main scale and the sub scale is read out from the moving distance of Moire fringes generated by overlapping the main scale and the sub scale using the main scale and the sub scale with the scale of the substantially same width and distance. <P>COPYRIGHT: (C)2007,JPO&INPIT

  A platform scale or a spring scale is used to measure the travel bag. Aside from cases where accurate weighing is required, such as transactions, there are many cases where it is only necessary to obtain an approximate value of weight, so a simple weighing method is desired. The present invention provides a means for weighing the weight of the bag by incorporating the scale into a handle such as a travel bag and lifting the bag by grasping the handle.

  The scale built into the handle should not interfere with the function of the handle under normal conditions. Therefore, the handle needs to have a mechanism for locking the function of the scale. Since the handle is usually fixed to the bag at two places, the built-in scale calculates the weight by adding the forces acting on these two places. It is necessary to provide a weighing mechanism at each of the two fixed positions and at the same time a mechanism for summing up the weighing results. If the contents of the bag are not evenly placed, the forces on the handle arms will not be balanced. The built-in scale overcomes this imbalance and requires a mechanism for weighing correctly. Further, since the reading of the measurement value is performed in a state where the heel is suspended by the arm, it is necessary to provide a display device that can be easily read even from a distance as long as the length of the arm. Furthermore, a function for protecting the balance is also required when the basket contains more than the allowable content.

  FIG. 1 is a front view showing a partial cross-sectional view of an embodiment of the present invention. A handle comprising a horizontal gripping part 1 and left and right arm parts 2 and 3 which are vertically expandable and contractible is connected to a heel with two wires 4 and 5 to suspend the heel. The left and right arm portions 2 and 3 are fixed to the heel body via the left and right mounting brackets 7. That is, the lower left end 6 of the left wire 4 is fixed to the shaft 8 of the left mounting bracket 7, passes through the grip portion 1 through the left arm portion 2, the left bending groove 9 such as a pulley, and the right end 10 is fixed to the handle. Similarly, the right wire 5 is fixed to the shaft (not shown) of the right mounting bracket, passes through the grip portion 1 via the right arm portion 3 and the right bent groove 11, and the left end 12 thereof is fixed to the handle.

  A main scale drive fitting 13 is attached to the left wire 4 and is connected via a pin 14 to a hole 16 of the main scale 15 in which a main scale is attached to a transparent material. On the other hand, a vernier drive fitting 17 is attached to the right wire 5 and is connected via a pin 18 to a hole 20 of a vernier 19 with a vernier scale. The main scale 15 and the sub-scale 19 are arranged in the groove 21 with the main scale on the top and the sub-scale on the bottom, both of which are slidable in the horizontal direction. The main scale moves to the left and the vernier moves to the right according to the extension of the left and right wires. Since each movement is in the opposite direction, the relative movement distance between the main scale and the sub-scale is equal to the sum of the elongation of the left and right wires. Relationship between stretch and weight The left and right wires have the same elastic characteristics so that the stretch rate is the same for the left and right wires, and at the same time, the distance between the left wire fixing position 10 and the mounting position of the main drive bracket 13, and the right It is necessary to make the distance between the wire fixing position 12 and the attachment position of the vernier drive metal fitting 17 equal.

  FIG. 1 shows the structure of the handle left arm. In this structure, the piston 24 is inserted into the cylinder 25 of the handle arm through the rod 23 attached to the shaft 8 of the mounting bracket. A stopper 26 is provided at the lower part of the cylinder 25 for the purpose of preventing the wire from extending too much due to the load. When there is an imbalance in load, the left and right wires are stretched differently, so the piston does not move smoothly. In order to overcome this problem, the piston 24 and the rod 23 are made of synthetic resin or the like, and the rod 23 has a structure that can be easily bent by an external force. When the handle is tilted from the horizontal due to the difference in elongation, the rod is bent and the piston is tilted together, so that the arm part can be smoothly expanded and contracted to enable accurate measurement.

  At the time of weighing, the lower end 29 of the handle arm part is separated from the arm fixing part 27, and the handle is freely expanded and contracted for weighing. When the scale is not used, a handle 28 such as a cap nut attached to the arm fixing portion 27 fixed to the shaft 8 of the handle mounting bracket is screwed into the arm lower end 29 so that the handle arm portion 2 and the arm fixing portion 27 To fix.

  FIG. 2 is a cross-sectional view of the handle grip portion of FIG. A state in which the wires 4 and 5, the vernier 19, the main measure 15, and the reading window 22 are attached from below to the groove 21 provided in the upper part of the handle is shown. Further, a main scale drive fitting 13 is attached to the wire 4.

  FIG. 3 shows an enlarged view of the main scale drive fitting. The main scale drive fitting 13 has a U-shaped structure that sandwiches two wires 4 and 5, and its original part is fixed to one wire 4, and the other part freely slides with the other wire 5 sandwiched between them. It has a structure to do. Thereby, the main scale drive pin 14 attached to the center part of the metal fitting moves in the longitudinal direction of the wire without being inclined. These movements are transmitted to the main scale 15 through the connecting hole 16. The vernier 19 is provided with a groove 31 so that the vernier 19 attached under the main ruler does not hinder the movement of the main measure drive pin 14.

  FIG. 4 is a top view of the main scale and the sub-scale placed on the groove 21, and only the main scale 15 is shown. The main scale and the sub-scale can slide independently in the longitudinal direction in the groove 21. In the figure, a scale 30 attached to the main scale 15 is shown. At the left end, a groove 31 provided on the vernier is indicated by a dotted line, and the main scale drive pin 14 connected to the main scale freely moves therethrough. The movement of the pin is transmitted to the main scale independently of the movement of the vernier. Moreover, although the groove | channel 32 provided in the main scale is shown by the continuous line at the right end part, the vernier drive pin 18 connected with the vernier freely moves in it. The movement of the pin is transmitted to the vernier independently of the movement of the main scale. Since the main scale is made of a transparent material, it is possible to observe the main scale and the sub-scale from the upper side.

  FIG. 5 and FIG. 6 show a state in which moire fringes are generated by making the widths and intervals of the scales attached to the main scale and the sub-scale substantially equal, and superimposing them. When the length of the 19th scale of the main scale is divided into 20 equal parts, that is, the number of divisions n of the main scale is 20, for example, FIG. When the zero scale position 33 coincides, FIG. 6 shows the case where the vernier moves to the right of the main scale 10/20 scale. The most sparse part of the moiré fringes appears at positions 33 and 34 of the scales of both scales in FIG. 5, and at positions 35 and 36 of the scale 10 of both scales in FIG. Measurement can be performed by reading these positions using a weight scale attached to the inside of the window 22 of the handle grip portion. In other words, the sparse part of the moire fringe serves as a guideline for weighing.

  Whereas the relative movement of the main scale and the sub-scale is the daily scale of the main scale, the sparse part of the moire fringe moves from the position of the main scale 0 to the position of the scale 20. That is, the movement of the pointer for measurement is expanded to 20 times the relative movement of the main scale and the vernier scale. In order to correctly determine and read the position of the sparse part of the moire fringe at the position of the main scale zero and the scale 20, in this case, it is necessary to extend the main scale and the vernier about 5 days on both sides. is there. In addition, when the densest part of the moire fringe comes to both ends as shown in FIG. 6, the densest part of the moire fringe is measured for measurement by regarding the left end as the position of the main scale and the minor scale. It can also be used as a guideline.

  In the above description, we considered the case where the zero point of the weight scale where there is no relative movement between the main scale and the vernier scale and the zero scale of both scales match. Fine adjustment work is required. By preparing the vernier twice as long as the above, and the main scale corresponding to the length, if the relative deviation between the main scale and the vernier is within one scale of the main scale, two moiré stripe pointers appearing. By setting the position on the left side to zero on the weight scale, measurement can be performed without fine adjustment work.

  By incorporating a scale into a handle such as a travel bag, you can measure the bag by holding the handle and lifting the bag. By incorporating a simple and inexpensive balance without impairing the function of the handle, it is possible to easily measure the bag. When boarding an aircraft, it can be expected that the procedure will proceed without delay if it can be confirmed whether there is an excess of weight before check-in.

  A handle such as a travel bag has a U-shape consisting of a pair of arms and a horizontal gripping part, and the ends of both arms are each weighed to a handle fixed to the bag body via a mounting bracket. When incorporating.

  When a piano wire having a diameter of 0.4 mm is used as the wire, the elongation becomes 1 mm for a load of 30 kg. If a main scale with a scale of 1 mm and a length of 50 mm is prepared, and a sub-scale with 49 mm divided into 50 parts, the weight can be read in units of 0.6 kg. If a main scale with a length of 100 mm and a sub-scale of 98 mm is prepared, the reading unit of the weight is the same, but the allowable displacement range with respect to the position of the scale of the main scale and the sub-scale is 1 mm.
