As shown in FIG. 6, the emphasis groove 42 supports the emphasis edge 8 with the upper side portion 8 a directed toward the distal end side of the short machine rod 4 and the middle side portion 8 d directed toward the proximal end side of the short machine rod 4.

  As shown in an enlarged view in FIG. 7, a curved portion 42 a in which the bottom surface of the priority groove 42 is curved downward is provided slightly behind the central portion in the front-rear direction of the priority groove 42. As shown in FIG. 7, the curved portion 42a is provided with a support recess 42b that is recessed in a conical shape. The support recess 42 b is a recess for supporting the priority edge 8 by supporting the support protrusion 81. The support depression 42b has an inclined surface that is slightly gentler than the inclined surface of the tip of the support protrusion 81 provided in the priority edge 8, and is configured so that the supported support protrusion 81 can move on the support depression 42b. Has been.

  FIG. 8 is a side view illustrating the outline of the configuration of the long machine rod 5. As shown in FIG. 8, a fulcrum groove 51 that receives the fulcrum edge 34 is formed on the lower end surface of the base end portion 5 b of the long machine shaft 5. Further, an emphasis groove 52 for receiving the emphasis edge 8 is formed on the upper end surface of the central portion 5c near the base end portion 5b. A load transmission groove 53 for receiving the suspension ring 6 is formed on the upper end surface of the central portion 5c near the tip portion 5a. In the long machine rod 5, the load applied to the cover 2 is transmitted to the emphasis groove 52 via the emphasis edge 8.

  The emphasis groove 52 has the same configuration as the emphasis groove 42 included in the short machine rod 4 except for the formation position of the bending portion 52a, and the support recess 52b included in the bending portion 52a is also curved of the emphasis groove 42. It has the same shape as the support hollow part 42b with which the part 42a is equipped. The emphasis groove 52 supports the emphasis edge 8 with the upper side portion 8a facing the proximal end side of the long machine shaft 5 and the middle side portion 8d facing the distal end side of the long machine shaft 5, and the support projection 81 supported by the support recess portion 52b. Support by doing. For this reason, the curved portion 52 a of the emphasis groove 52 is provided slightly forward of the central portion in the front-rear direction of the long machine shaft 5.

  Next, the operation | movement at the time of the measurement with the weight scale 1 of this embodiment is demonstrated. In the state where the base 3 is placed on the floor surface, as shown in FIG. 3, each short machine rod 4 included in the scale 1 is supported by the fulcrum groove 41 by the fulcrum edge 34 and the base end portion 4 b. The tip portion 4 a is supported by the action point groove 43 by the suspension ring 6. Further, each long machine rod 5 is supported by the fulcrum edge 34 at the base end portion 5b by the fulcrum groove 51, and by the suspension ring 6 by the load transmission groove 53 by the central portion 5c near the front end portion 5a. 5 a is supported by a connecting piece 71. In this state, each of the flanges 4 and 5 supports the cover 2 with the emphasis grooves 42 and 52 through the emphasis edge 8. Although not shown in the drawing, the urging force of a side spring interposed between the load receiving portion 21 of the cover 2 and the bottom plate portion 31 of the base 3 causes the peripheral edge portion of the spring fixing hole 35 of the bottom plate portion 31 of the base 3 to move. The locking piece 28 of the load receiving portion 21 of the cover 2 is biased.

  Due to the weight of the cover 2 and the urging force of the side spring, a load of a predetermined magnitude is applied to each of the flanges 4 and 5 via the priority edge 8. This load received by the short machine rod 4 is transmitted to the long machine rod 5 via the suspension ring 6. The long machine rod 5 transmits the load directly received from the priority edge 8 and the load transmitted from the short machine rod 4 via the suspension ring 6 to the connecting piece 71 to which the tip portion 5a is fixed.

  The load transmitted to the connecting piece 71 in this way is transmitted from the transmission rod 72 to the load cell 75 via the terminal edge 73 and the mounting piece 74, and the load cell 75 is bent. A force that presses the cover 2 upward against the load applied from the priority edge 8 acts on each of the flanges 4 and 5 by the elastic force generated in the bent load cell 75. Thereby, the attachment position of the cover 2 with respect to the base 3 is maintained at a predetermined position.

  In this state, when a load is applied to the cover 2 by, for example, the subject placing both feet on the placement portion 2 b of the cover 2, each of the heels 4, 5 passes from the cover edge 24 of the cover 2 through the priority edge 8. The load is transmitted to The load applied in this manner acts to rotate the flanges 4 and 5 toward the bottom plate 31 of the base 3 with the contact point with the fulcrum edge 34 as a fulcrum, and the amount of deflection of the load cell 75 increases. The load is measured by detecting the change in the deflection amount.

  When the subject places his / her feet on the placement portion 2b of the cover 2, a load in the horizontal direction acts on the cover 2, and the parts such as the ridges 4, 5 and the edges 8, 24, 34, etc. Due to the influence of the finished state, a force may be exerted to shift the supporting position of the priority edge 8 by the flanges 4 and 5 from a predetermined position. As a result, the load position applied to the movable part of the load cell 75 is different between the case where the supporting position of the priority edge 8 by each of the flanges 4 and 5 is deviated from the predetermined position and this position is at the predetermined position. There is a possibility that a large error occurs in the value.

  However, the weight scale 1 of the present embodiment has the support protrusion 81 provided on the middle side 8d supported by the support recesses 42b and 52b provided in the priority grooves 42 and 52 of the flanges 4 and 5, respectively. Since the edge 8 is supported by the flanges 4 and 5, even if a load directed in any direction in the horizontal direction is applied to the priority edge 8, the support protrusion 81 is supported by the inclined surfaces of the support recess portions 42 b and 52 b. Horizontal movement can be hindered. That is, it moves upward on the inclined surface of the support recesses 42b and 52b from the innermost part located at the center of the support recesses 42b and 52b toward the periphery of the support recesses 42b and 52b, and the support recesses In order for the support protrusion 81 to move to the outside of the portions 42b and 52b, it is necessary to apply a greater force to the priority edge 8 than to move on the flat surface. In addition, the support protrusions 81 that have not been able to climb up the inclined surfaces of the support recesses 42b and 52b are moved down the inclined surfaces of the support recesses 42b and 52b due to the load applied from the cover edge 24 and the weight of the emphasis edge 8. Return to the back again. For this reason, even if a load is applied in any direction in the horizontal direction with respect to the cover 2, the supporting position of the emphasis edge 8 by the flanges 4 and 5 is the support protrusion 81 at the innermost part of the support recesses 42b and 52b. It becomes easy to be kept at a predetermined position. As a result, the measurement that occurs when the load is applied toward the side of the cover 2 and the support position of the priority edge 8 on each of the heels 4 and 5 is shifted depending on the finished state of each component constituting the scale 1. The error of the value can be suppressed and the accuracy of weighing can be increased.

  In addition, the support depressions 42b and 52b have an inclined surface slightly gentler than the inclined surface of the support protrusion 81, and the support protrusion 81 can be moved on the support depressions 42b and 52b. The support protrusion 81 can be smoothly moved on the inclined surfaces of the support recess portions 42b and 52b. For this reason, along with the movement between the support recesses 42b and 52b and the support protrusion 81, the wear and the damage of the priority edge 8 and each of the flanges 4 and 5 are suppressed. It is possible to prevent the attachment posture of the priority edge 8 to the priority grooves 42 and 52 of the flanges 4 and 5 from changing. Therefore, the measurement accuracy can be further increased.

  Further, since the tip end portions of the support protrusions 81 having a conical diameter are supported by the support recess portions 42b and 52b that are recessed in a conical shape, the support protrusions 81 on the inclined surfaces of the support recess portions 42b and 52b are supported. Can be moved more smoothly. For this reason, along with the movement between the support recesses 42b and 52b and the support protrusion 81, the wear generated on both and the damage of the priority edge 8 and the flanges 4 and 5 are effectively suppressed, and the wear and damage are generated. Accordingly, it is possible to effectively prevent the attachment posture of the priority edge 8 to the priority grooves 42 and 52 of the flanges 4 and 5 from changing. Therefore, the measurement accuracy can be further increased.

  In the description of the above embodiment, the direction in which the priority edge 8 is supported is different between the short machine rod 4 and the long machine rod 5, but the direction in which the edge edge 8 is supported is arbitrary. The direction in which the priority edge 8 is supported may be the same. Moreover, the direction which supports the priority edge 8 is also arbitrary, and the upper side part 8a does not necessarily need to face the front end side or rear end side of each of the flanges 4 and 5. Moreover, if it is spanned between each cover edge 24 of the connection part 23 and each support part 82 is supported by the connection groove | channel 24a, if it will be supported by each ridge 4 and 5 by the support protrusion 81, it will be important. The shape of the edge 8 is also arbitrary.

  In the description of the above embodiment, the support protrusion 81 is configured by fitting the rod-like body 9 into the fitting hole 8d1 formed in the middle side 8d. However, the configuration of the support protrusion 81 is arbitrary as long as the supporting edge 81 can be supported by the flanges 4 and 5 by being supported by the support recesses 42b and 52b included in the flanges 4 and 5. And may be formed integrally with the middle side portion 8d. Further, when the support protrusion 81 is formed separately from the priority edge 8, the attachment method is also arbitrary.

  In the description of the above embodiment, the case where the support protrusion 81 included in the priority edge 8 is supported by the support recess portions 42b and 52b included in the flanges 4 and 5 has been described. However, the embossed edge 8 is supported by each of the collars 4 and 5 by the depressions provided on either one of the collars 4 and 5 and the emphasis edge 8 and the projection provided on the other being supported. If it is, the structure is arbitrary. For example, the support protrusions included in the flanges 4 and 5 may be supported by the support recesses included in the priority edge 8, and either the short machine rod 4 or the long machine rod 5 includes the support protrusions, and the rest It is good also as a structure which is equipped with a support hollow part and the emphasis edge 8 is equipped with a support protrusion or a support hollow part according to which each ridge 4,5 is supported.

  In the description of the above embodiment, the emphasis grooves 42 and 52 have a side surface shape in which the upper edge portions of the flanges 4 and 5 are cut out in a rectangular shape, and the emphasis grooves 42 and 52 are curved portions 42a. , 52a is provided with the support recesses 42b, 52b. However, the configuration of the emphasis grooves 42 and 52 is arbitrary as long as the emphasis edge 8 can be supported by the flanges 4 and 5 by supporting the support protrusion 81 provided on the emphasis edge 8 by the support recess portions 42b and 52b. The curved portions 42a and 52a are not necessarily provided.

  Further, if the supporting edge 81 provided on the emphasis edge 8 is supported by the supporting recess portions 42b and 52b provided on the flanges 4 and 5, the emphasis edge 8 can be supported on the flanges 4 and 5, respectively. The shapes of the protrusions 81 and the support recesses 42b and 52b are arbitrary. The support recesses 42b and 52b are necessarily recessed in a conical shape, and the support protrusion 81 does not have to have a conical diameter-reduced tip.
