Description

  The present invention relates to a tilting instrument used to measure the verticality of pillars, walls, etc. and the horizontality of beams, floors, etc., for example, at construction sites.

  Conventionally, as this type of tilting instrument, as disclosed in Patent Document 1, for example, it is possible to accurately measure the verticality of a column or wall surface about 1 meter from the floor and the horizontality of a beam or floor surface. A tilter has been proposed.

  By the way, in the above-mentioned Patent Document 1, the upper end and the lower end of the support column are slightly above the lower end of the support column, and the upper arm and the lower arm are horizontally fixed to each other. There are described two types of side tilters of a substantially U-shaped type in side view, each of which has an upper arm and a lower arm that are fixed horizontally.

  The both types of side tilters are each provided with a fitting groove and a long hole of the object finger in the longitudinal direction of the lower arm, and each provided with a long hole and a scale in the fitting groove. The index finger having an elongated hole is slidably fitted in the elongated hole of the object finger, and is formed on the lower surface of the upper arm. The fastened strip is inserted through the elongated hole of the index body and the elongated holes of the fingers and the lower arm, and the weight is hung in the lower arm lower space at the lower end of the strip. Yes. The weights are commercially available and are formed of a smooth cylindrical metal member (iron material) with a glossy surface.

Utility Model Registration No. 3068279

  However, in the above-mentioned Patent Document 1, there is no portion for storing the metal weight when the tilting instrument is not used, so that the weight is attached to the metal side tilting device main body or other hard member in the vicinity thereof. Even when it comes into contact (collision) or is stored in a cardboard box, bag, etc., the weight is often contained together with the tilting instrument body in an exposed state, so contact with the side tilter body (for example, a column) ( The surface is easily scratched by collision), and there is a risk of hindering accurate measurement.

  Therefore, the present invention was created in view of the existing circumstances as described above, and a weight insertion hole is provided in the support column constituting the side tilter body, and the weight inserted in the insertion hole is firmly secured with a magnet. It is an object of the present invention to provide a clinometer which is formed by improving the top of the weight so that the weight can be easily pulled out by a fingertip.

  In order to solve the above-described problems, in the present invention, an insertion hole for a weight when not in use is provided in a support column, and a magnet for attracting the weight inserted into the insertion hole is disposed in the insertion hole. The weight is formed so as to protrude a predetermined length above the insertion hole when it is attracted to the magnet in the insertion hole of the support column, and the weight serving as a protruding end thereof An anti-slip gripping part for facilitating extraction of the weight by the fingertip is provided on the upper part.

  The anti-slip gripping portion is formed at the upper end of a weight formed in a columnar shape by an annular flange portion larger than the width diameter of the weight.

  Further, the anti-slip gripping portion is formed by providing a plurality of annular grooves at predetermined intervals on the outer periphery of the upper end of the column-shaped weight.

  Furthermore, the anti-slip gripping portion is formed by providing a pair of constricted portions having a substantially arc-shaped concave section at a position below the upper end of the weight formed in a columnar shape at the opposing position on the entire circumference.

  According to the present invention, by inserting a weight into the insertion hole provided in the support column, it is possible to prevent the weight from coming into contact (collision) with the side tilter body or other hard members when not in use. In addition, it is possible to easily pull out the weight that is attracted by the magnet in the insertion hole against the magnet's attracting force by gripping and pulling the anti-slip gripping portion formed on the top with a fingertip.

  That is, the present invention provides a weight insertion hole when not in use in the support column, and a magnet for adsorbing the weight inserted in the insertion hole is disposed in the insertion hole, When the weight is attracted to the magnet in the insertion hole of the support column, it is formed so as to protrude a predetermined length above the insertion hole, and the weight is pulled out by the fingertip of the weight on the upper part of the weight that becomes the protruding end. Since the anti-slip gripping part is provided to make it easier to prevent the falling of the weight from the insertion hole, the anti-slip gripping part can be used at the time of use or when the weight is replaced with a new one. By picking and pulling the fingertip with the fingertip, the weight can be easily and reliably pulled out from the insertion hole against the attracting force of the magnet without the fingertip slipping on the weight surface.

  Since the non-slip gripping portion is formed by an annular flange portion larger than the width diameter of the weight on the upper end of the weight formed in a columnar shape, the flange portion is gripped and pulled so as to be locked with a fingertip. Thus, the weight can be easily and reliably pulled out from the insertion hole against the magnet's attractive force.

  The non-slip gripping portion is provided with a plurality of annular grooves on the outer periphery of the upper end formed in a columnar shape at a predetermined interval, so that the fingertip can be grooved by picking and pulling the groove with the fingertip. Thus, the weight can be easily and reliably pulled out of the insertion hole against the magnet's attractive force without slipping.

  The anti-slip gripping portion has a pair of constricted portions having a substantially arc-shaped cross section at a position below the upper end of the column-shaped weight, and the constricted portions are gripped with a fingertip. By pulling, the fingertip is locked at the constricted portion, and the weight can be easily and reliably pulled out from the insertion hole against the magnet's attracting force without slipping.

It is DD expanded sectional drawing of FIG. This shows another usage state with a substantially U-shaped tilting device in side view, (a) the floor surface is not tilted, (b) is the floor surface is tilted to the right, and (c) is the floor surface tilted to the left. It is each side view when it exists in a state.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  In the present invention, the column 1 constituting the tilting instrument is formed in a flat rectangular tube shape having a horizontally long cross-sectional shape with a predetermined length on the front plate 1A, the back plate 1B and the both side plates 1C. In addition, the said support | pillar 1 may be aluminum, a brass, and another metal material.

  The side tilter of the present invention includes an upper arm 2 made of a metal plate fixed to the upper end of the support column 1 so as to protrude forward at a required length, and a position slightly above the lower end of the support column 1, that is, the support column 1 on the floor surface Q. A lower arm 3 made of a metal plate supported and fixed by a bracket 4 in parallel to the upper arm 2 so as to have a space S that can be suspended in a contactless state when a weight 26, which will be described later, is erected. Side-view substantially F-shaped type (see FIGS. 1, 2, 10, and 12), and side-arm substantially U-shaped in which the lower arm 3 is provided at the lower end of the column 1 in parallel with the upper arm 2. There are types (see FIGS. 11 and 14).

  And in the said side view substantially F type type, while the lower part of the support | pillar 1 is formed in the leg part of predetermined length, the support plate 27 is provided in this leg part lower end. In addition, a contact piece 27A protrudes from the rear portion of the support plate 27 by a predetermined length, and a bracket 28 is also provided at the upper rear side of the support column 1 so as to have the same length as the protrusion length of the leg plate. Thus, when the tilting column 1 is brought into contact with the column P or the like during use, the back plate 1B of the column 1 and the column P or the like are held at equal intervals (FIGS. 10 and 10). 12).

  On the other hand, in the case of a substantially U-shaped type in a side view, the tips of the upper arm 2 and the lower arm 3 fixed to both ends of the column 1 are brought into direct contact with the column P or the like (see FIG. 11). In this side-view substantially U-shaped type, the inclination measurement position of the column P is vertical from the floor Q to the bottom of the scale plate 9 by a predetermined height (for example, 21.5 cm) according to the building guidance guidelines and the like. Used when specified to measure. Further, the substantially U-shaped type in a side view is suitable for measuring the level of the floor surface Q. Details of this will be described later.

  Thus, as shown in FIGS. 1, 2, 10, 12, and 13, the lower arm 3 is slidably engaged by the rack and pinion mechanism 14 along the longitudinal direction of the upper surface. The scale plate 9 is configured to move back and forth in the lower arm 3 through the rack and pinion mechanism 14 by rotating the adjustment knob 15 connected to the pinion. Then, the front end of the stopper plate 16 connected to the knob 17 is engaged with and disengaged from the V-shaped groove 13 formed on the side surface of the scale plate 9 by turning the front handle 17 after the scale plate 9 is advanced and retracted. Thus, the scale plate 9 can be fixed to or released from the lower arm 3 at a predetermined position.

The scale plate 9 has a long hole 10 formed so as to correspond to a long hole (not shown) formed in the longitudinal center of the lower arm 3, and a scale 11 is engraved on the upper surface of both sides of the long hole 10. It is installed. In addition, a transparent hard plastic index body 20 is slidably fitted in the long hole 10. Further, an elongated hole 23 having a width substantially the same as that of a strip 25 described later is formed in the indicator body 20 so as to be orthogonal to the elongated hole 10, and an indicator 24 is provided on both longitudinal sides of the elongated hole 23. Each carved.
In the figure, reference numeral 19 denotes a reference index provided on the upper surface of the lower arm 3.

  On the other hand, on the lower surface of the upper arm 2, for example, an upper end of a strip 25 formed by a plastic thread or the like is fastened, and at the lower end of the strip 25, an elongated hole of the index body 20 in use. 23, a long hole 10 of the scale plate 9 and a long hole (not shown) of the lower arm 3 are sequentially inserted, and a metal (iron) weight 26 is suspended in the lower space S. And the attachment position of the strip 25 with respect to the upper arm 2 is, when the support column 1 is set up vertically, the strip 25 inserted through each hole of the lower arm 3 is placed on the scale plate 9 in the reference state shown in FIGS. It corresponds to the 0 point of the scale 11 that has been engraved.

  By the way, the upper arm 2 and the lower arm 3 are formed in the same length in FIGS. 1 to 11, but the lower arm 3 is formed shorter than the upper arm 2 in FIGS. By turning the knob 15, the scale plate 9 is set to have the same length as the upper arm 2 by projecting the scale plate 9 from the lower arm 3 by a predetermined length y (see FIG. 13). Also in this case, the mounting position of the upper arm 2 coincides with the 0 point of the scale 11 carved on the scale plate 9 in the reference state shown in FIG. ing.

  Both of them can measure the verticality and the horizontality, but in the latter case, particularly when measuring the horizontality, it is excellent in workability and suitable. The reason will be described later.

  An insertion hole 31 for the weight 26 is provided at an appropriate portion of the front plate 1A of the column 1 such as a lower position. The insertion hole 31 of the weight 26 is provided in the front plate 1A (on the opposite side of the surface facing the column P) below the lower arm 3 in the side view substantially F-shaped type. Then, it is provided on the back plate 1 </ b> B (surface side facing the column P etc.) above the lower arm 3.

  That is, as shown in FIG. 3, the insertion hole 31 of the weight 26 is provided with a circular hole portion 1d through which the weight 26 is passed through the front plate 1A of the support column 1, and the hole 1d has a circular shape in front view. It is formed by fitting and fixing a flange-shaped weight guide 32. The inner diameter of the circular weight guide 32 is formed to be the same as or slightly larger than the lower outer diameter of the weight 26. Details of the weight 26 will be described later.

  A circular magnet 36 is disposed inside the back plate 1B of the support column 1 so as to face the insertion hole 31 of the weight 26. The magnet 36 attracts the tip of the weight 26 inserted into the insertion hole 31 through the weight guide 32.

  More specifically, as shown in FIGS. 8 and 9, for example, the magnet 36 is made of a disc-shaped ferrite magnet that adsorbs an iron material, and a circular mounting hole 35 is opened at the center, and the weight 26 is A ring-shaped cap 33 made of stainless steel or the like is fitted so as to cover the outer periphery and the rear surface except for the front surface to be adsorbed. Further, a circular support hole 34 facing the mounting hole 35 at the center of the magnet 36 and having a slightly smaller diameter than the mounting hole 35 is opened at the center of the cap 33. The locking protrusion 1e protruding inside is fitted.

  In this way, the locking projections 1e protruding from the inner side of the back plate 1B of the support column 1 are fitted and fixed in the support holes 34 of the cap 33 in which the magnets 36 are stored, thereby preventing the cap 33 from being pulled out. ing. The weight 26 inserted into the insertion hole 31 of the weight 26 on the front plate 1A of the support 1 via the weight guide 32 is located until the tip contacts the magnet 36 provided on the inner side of the back plate 1B of the support 1. The weight 26 is inserted and attracted by the magnetic force of the magnet 36 (see FIG. 4).

  The weight 26 is preferably cylindrical, but is not necessarily limited to this, and may be, for example, a prismatic shape. The weight 26 is entirely made of iron that is attracted to the magnet 36, but the lower end in contact with the magnet 36 may be made of iron, and other portions may be made of other materials. Further, the weight 26 is inserted into the insertion hole 31 of the weight 26 of the support 1, and when the weight 26 is attracted to the magnet 36, the upper end portion protrudes from above the weight guide 32 of the insertion hole 31 of the weight 26. It is formed in length. And as shown in FIG. 4, the anti-slip | skid grip part 40 of this invention for making extraction easy is provided in the upper part of the weight 26 which is this protrusion part.

  That is, since the weight 26 inserted into the insertion hole 31 of the weight 26 is formed on a smooth surface with a chrome plating on its surface, the upper part of the weight 26 is picked up from the insertion hole 31 of the weight 26 with a fingertip. When extracting, the fingertip is very slippery. In addition, the weight 26 requires a considerable amount of force because of the weight of the iron weight 26 in order to grasp and pull out the upper portion attracted by the magnet 36 disposed on the lower surface of the insertion hole 31. is there.

  Therefore, in the present invention, the anti-slip gripping portion 40 is provided so that the metal weight 26 having a smooth surface against the attractive force and weight of the magnet 36 can be easily picked and pulled out from the insertion hole 31 with the fingertip. It is formed on the upper end of the weight 26.

  Next, a specific example of the shape of the weight 26 will be described in detail.

  As shown in FIGS. 4 and 5, the flange portion 41 functioning as the anti-slip gripping portion 40 is a disc-shaped “pick portion” slightly larger than the outer diameter of the columnar weight 26, and is attached to the upper end of the weight 26. It is provided integrally. In addition, you may provide this flange part 41 in a different body by screwing type.

  As another example of the non-slip gripping portion 40, as shown in FIG. 6, a plurality of annular slip grooves 42 for anti-slip may be provided on the outer periphery of the upper end of the column-shaped weight 26 at predetermined intervals. .

  As yet another example of the non-slip gripping portion 40, as shown in FIG. 7, a pair of constricted portions (concave portions) 43 having a substantially arc-shaped cross section are formed opposite to each other at a position below the upper end of a columnar weight 26. Alternatively, the upper part of the constricted portion may be picked up with a fingertip by providing it all around.

  In addition, a screw part can be provided at the upper end of the cylindrical body, and the nut can be picked up by a fingertip by screwing the nut onto the screw part (not shown).

  Further, as shown in FIGS. 4, 5, 6, and 7, a screw-type fixing tool 51 for fixing the strip 25 is provided at the center of the upper end of the weight 26. As the fixture 51, a vertical hole 52 through which the strip 25 passes is formed in the center. The vertical hole 52 includes a narrow through hole 53 in the upper portion of the strip 25 and a wide locking hole 54 in which the lower portion is locked with the lower end of the strip 25 tied. In addition, it is sufficient if the weight 26 can be fixed to the lower end of the strip 25. For example, a ring-shaped stopper or the like may be provided on the upper surface of the weight 26.

  In the illustrated example, it is described as measuring the verticality of the column P or the like. However, a level 29 by a bubble tube is provided at the center of the column 1, and thereby the level of the floor surface Q (or beam) or the like. Can also be measured.

  Next, a method for using the tilting instrument according to the present invention will be described in detail.

  When measuring the perpendicularity of the pillar P at a construction site or the like with the above-described side-view substantially F-shaped type tilting device, first, the anti-slip gripping portion 40 of the weight 26 is picked with a fingertip, and the insertion hole 31 of the weight 26 is removed. The weight 26 is pulled out against the attractive force of the magnet 36 and the weight of the weight 26 itself. Next, the column 1 is set up by placing the bottom surface of the contact piece 27 </ b> A at the lower end of the column 1 on the floor surface Q. Then, both end surfaces of the contact piece 27A at the lower end of the column 1 and the bracket (contact piece) 28 above the column 1 are brought into contact with the column P, and the elongated hole 23 of the indicator body 20 and the slot of the scale plate 9 are formed. When the strip 25 with the weight 26 hanging down through the long hole (not shown) of the lower arm 3 and the lower arm 3 is stationary, the scale 25 of the scale plate 9 is read by the strip 25, and the height of 1 meter is thereby read. The perpendicularity of the column P is detected.

  At this time, when the strip 25 coincides with the 0 point of the scale 11 on the scale plate, that is, as shown in FIG. 13, the index 24 on both sides of the elongated hole 23 in the index body 20 into which the strip 25 is inserted, and the scale When the zero point of 11 and the reference index 19 of the lower arm 3 are arranged on a straight line in a direction perpendicular to the long hole 10 of the scale plate 9, the column P is measured as vertical, whereas from the zero point When the column P is displaced to the left or right, the inclination of the column P is measured according to the displacement width.

  When measuring the verticality of the pillar P at a construction site or the like with the above-described side-view substantially U-shaped tilting device, first, similarly to the above, first, the anti-slip gripping portion 40 of the weight 26 is picked with a fingertip, and the weight The weight 26 is pulled out from the insertion hole 31 of 26. Next, the tips of the upper arm 2 and the lower arm 3 fixed to both ends of the column 1 are brought into direct contact with the column P or the like. In this side-view substantially U-shaped type, the inclination measurement position of the column P is vertical from the floor Q to the bottom of the scale plate 9 by a predetermined height (for example, 21.5 cm) according to the building guidance guidelines and the like. It is prescribed to measure.

  On the other hand, when measuring the level of the floor surface Q, the tips of the upper arm 2 and the lower arm 3 at both ends of the column 1 are brought into contact with the floor surface Q, and the position of the bubbles in the level 29 is read. . That is, the tip of the scale plate 9 is pulled into the lower arm 3 so that the bubble of the level 29 is located in the center, or the tip of the scale plate 9 is further protruded from the state, or the scale plate 9 at that time If the scale 11 is read with the index 24 and the reference index 19, the level of the floor surface Q can be detected.

  When measuring the level of the floor surface Q using a side tilting device in which the scale plate 9 protrudes from the tip of the lower arm 3 in the substantially U-shaped tilting device in side view, as described above, FIG. ) Shows a non-tilted state, and FIG. 14B shows a right-tilted state. FIG. 14 (c) shows a left-tilted state. In any case, the scale plate 9 side is adjusted so that the bubble of the level 29 is positioned at the center while operating the adjustment knob 15 on the right side (or left side). Therefore, the workability is good in that it can be measured.

  That is, when the side tilter with the upper and lower arms 2 and 3 having the same length is used, it is necessary to replace the side tilter main body in the left and right direction every time the left and right tilts are measured. Therefore, the use of the side tilter is suitable for measuring the level.

  Incidentally, when measuring the horizontality in this way, an unnecessary weight 26 is preferably inserted into the insertion hole 31 of the column 1. This is because the iron weight 26 does not fall out of the insertion hole 31 due to the attractive force of the magnet 36.
