Abstract

PROBLEM TO BE SOLVED: To provide an electronic platform scale of good operativity which has an angle adjusting mechanism of a small number of components where the angle of a display is easily adjusted while the set angel is surely kept after adjustment. SOLUTION: A supporting axis part 2 is mounted on the top part of a pole 18 supporting a display device 17, with a slide pin 4 which is energized by a spring force to a support part 1 engaged with the supporting axis part 2 vertically movably. A plurality of engagement holes 3 are opened along the circumference whose radius is equal to the distance from the center of the supporting axis part 2 to the slide pin 4. The slide pin 4 is energized by the spring force and inserted into one of engagement holes 3 for regulating rotation. Accordingly, when the slide pin 4 is ejected from the engagement hole 3, the regulation of rotation is released to allow angel adjustment in the vertical direction of the support part 1 while the rotation of the support part 1 is regulated when the slide pin 4 is inserted into the engagement hole 3, permitting the display device 17 to be surely fixed at the position.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a platform for measuring the weight of an object to be measured.

[0002]

2. Description of the Related Art An electronic table can be used as a table for measuring the weight of a measured object. Such an electronic table usually has a weighing section 15 for loading the measured object as shown in FIG. And a base 16 for accommodating a measurement unit such as a load cell, a display 17 for displaying measured values and printing out the results, and a pole 18 for supporting the display 17. When the measurement object is added to or subtracted from the measuring unit 15, the zero point of the platform and the measurement value must be checked, so that the display 17 is adjusted to the angle of view of the measurement person so that the measurement value can be easily checked by the measurement person. It is necessary to adjust the angle. There are various types of adjustment mechanisms for performing this angle adjustment.
The optimal method is selected in consideration of the weight, the operability of adjusting the angle, the cost, and the like. For example, the weight of the display 17 is several kg.
Conventionally, an angle adjusting mechanism having a structure as shown in FIG. 3 is found. That is, the upper end of the support head 8 fitted to the pole 18 is formed in a T-shape, and the support shaft 9 is laterally provided. On the other hand, a C-shaped fastening seat 10 is protruded from the support portion 1 of the display 17 and inserted into the support shaft 9, and the fastening seat 10 is fixed to the fixing screw 1.
It is fixed to the support shaft 9 by tightening with the nut 1 and the nut 12. When the tightening is loosened, the display surface of the display 17 rotates freely in the vertical direction, and the display 17 can be adjusted to an arbitrary angle by tightening the fixing screw 11 at an appropriate position.

[0003]

In such a conventional electronic stand alone, the principle of the angle adjusting mechanism of the display is simple, and there is an advantage that the display 17 can be adjusted to an arbitrary angle. A tool is required for tightening the fixing screw 11, and the position may be erroneously deviated during the tightening operation and readjustment may be performed, which is disadvantageous in operability. Further, there is a risk that the fixing screw 11 is loosened during use and the display 17 is tilted suddenly. As another angle adjustment method,
For example, there are various mechanisms such as a ratchet, a friction plate urged against an elastic body, and a mechanism for adjusting the angle using a pulse motor or the like and fixing the lens at a set position. However, these generally have a complicated structure and tend to increase the number of parts. On the other hand, the display 17 consisting of only the electronic stand can be read by the operator by appropriately changing his or her own posture, so that the adjustment of the angle does not require strictness, and can be easily adjusted. If the rotation of the display 17 can be regulated reliably after the adjustment, the purpose can be sufficiently achieved. The present invention has been made in view of such problems,
It is an object of the present invention to provide a platform having a simple structure and an operable table provided with an angle adjusting mechanism capable of securely fixing the display 17.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a weighing unit for loading an object to be measured, a base unit for accommodating a weight measuring unit for the object to be measured, and a weighing unit are provided. And a pole for supporting the display, and a support having a support for rotatably supporting the display about a horizontal support shaft set on the top of the pole. And a slide pin which is urged to the pole side and protrudes, and which is engaged on a circle having a radius equal to the distance from the center of the support shaft to the slide pin and which is bored on the pole side and whose tip is engaged when the slide pin protrudes. A mating hole is provided so that the angle of the display can be adjusted by engaging and disengaging the slide pin with the engaging hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of an electronic stand only according to the present invention will be described below with reference to FIGS.
Note that components of the electronic stand alone will be described using the same reference numerals as in FIG. FIG. 1A is a side view of the display 17, and FIG.
(B) shows the AA view of FIG.1 (a). Support head 8
A plurality of engagement holes 3 are formed in the support shaft portion 2 fixed to the support shaft 1, and the support portion 1 of the display 17 is rotatably engaged with the support shaft portion 2. As shown in FIG. 1B, the slide pin 4 is loosely attached to the support 1, and a coil spring 6 sandwiched between an E-ring 7 inserted into the slide pin 4 and a member of the support 1. , The tip is normally inserted into the engagement hole 3, the rotation of the support 1 is restricted, and the display 17 is fixed at that position. On the other hand, as shown in FIG. 2B, if the slide pin knob 5 is moved in the XR direction, the tip of the slide pin 4 is inserted and removed from the engagement hole 3 so that the support portion 1 can be rotated. Therefore, the display surface of the display 17 can be set freely.

Next, the operation of the above configuration will be described. The support head 8 shown in FIG. 1 is mounted on the top of a columnar pole 18 just on the electronic stand, and can rotate left and right around the axis of the pole 18, but this rotation is performed by a fixed knob (not shown). Is configured to be regulated. First, as shown in FIG. 2, when the tip of the slide pin 4 is pulled out of the engagement hole 3 by pulling the knob 5 of the slide pin 4 in the XR direction and moving, the support portion 1 is attached to the support head 8. The display 17 can be freely rotated in the vertical direction, and the display 17 can be adjusted to almost any angle. After adjusting to an appropriate angle in this manner, when the user releases the knob 5, the slide pin 4 is urged by the spring 6 and moves in the XL direction.
As shown in FIG. 1, the tip of the slide pin 4 is inserted into the engagement hole 3, and the rotation of the display 17 is restricted and fixed at that position.

The operation will be described in more detail with reference to FIG. FIG. 1A is a side view of the display 17. The support shaft 2 extends from the center of the support shaft 2 to the tip of the slide pin 4 over an area covering the angle adjustment range of the support 1. Along the circumference whose radius is the distance to
About three engaging holes 3 are formed. A slide pin 4 is inserted from the outside of the support portion 1 to rotatably engage the support portion 1 and the support shaft portion 2 and to restrict rotation of the display main body at an appropriate angle. FIG. 1B illustrates a view taken along the line AA passing through the center of one of the plurality of engagement holes 3. The engaging hole 3 is conically opened with respect to the slide pin 4 in order to easily accommodate the tip of the slide pin 4. On the other hand, slide pin 4
Is formed in a tapered conical shape in accordance with the shape of the engagement hole 3. The E-ring 7 is locked at a position where the tip of the slide pin 4 is sufficiently tightened to the depth of the engagement hole 3,
Since the coil spring 6 is held between the E-ring 7 and the inner surface of the outer wall of the support portion 1, the slide pin 4 is always urged in the XL direction.

When adjusting the angle of the support 1 in the vertical direction, to prevent the support 1 from suddenly falling forward due to its weight, lightly put a hand thereon. Then, pull the knob 5 of the slide pin 4 lightly with the finger in the XR direction to move it, and pull out the tip of the slide pin 4 from the engagement hole 3.
As shown in FIG. 2, the support portion 1 can freely rotate in the vertical direction. Next, when the operator releases his / her finger from the knob 5 at an appropriate position, the slide pin 4 urged by the coil spring 6 is automatically inserted into the engagement hole 3, and FIG.
The state shown in (b) is reached, and the rotation of the support portion 1 is restricted and fixed at that position. By performing the above operation, the display surface of the display 17 can be set to an easy-to-view angle. Further, once the angle of the display 17 is adjusted, the display 17 is stably and reliably held at the position, and does not cause a sudden tilting phenomenon.

In the illustrated example, the support head 8 and the support shaft 2 are individually formed and then bonded and integrated for processing reasons. However, they may be integrally formed from the beginning. The cross-sectional shape of the slide pin 4 and the engagement hole 3 is not limited to a conical shape, and may be, for example, a cylindrical shape or a square shape. Further, the slide pin 4 may be biased by using a leaf spring or another appropriate elastic body instead of the coil spring 6. The number of the engagement holes 3 has been described as 8 to 10, but is not limited to this range.

[0010]

According to the present invention, as described above, the number of components is small, and the operation of adjusting the angle of the display can be easily performed manually without the need for tools.
