Description

  The present invention relates to a level attachment that can easily and accurately attach a commercially available level to piping, and can accurately measure the gradient of the piping.

  Conventionally, when piping work or the like is performed, a level is used to measure the slope of the pipe. In particular, in indoor drain pipes such as houses, drainage clogging may occur due to stagnation of drainage filth and the like unless a certain gradient is applied to the drain pipe, and it is necessary to accurately measure the slope. Therefore, when laying drainage pipes, it is necessary to work while confirming that an appropriate slope is always secured.

  As the gradient device 100 for measuring the gradient of the pipe, for example, as shown in FIG. 21, a main body 103 formed in a circular shape having a display unit 102 indicating the gradient of the pipe 101, and an outer peripheral surface of the pipe 101. In contact therewith, the display unit 102 is supported on the pipe 101, and the parts 104a and 104b that are in contact with the pipe 101 include support parts 105a and 105b provided with anti-slip means (for example, Patent Document 1). . Moreover, as a conventional level, a non-magnet type level without a magnet and a magnetic level with a magnet on the lower surface are commercially available. Since the magnetic level is provided with a magnet on the lower surface, it can be magnetically attached to a metal pipe or the like.

  However, in the gradient device shown in Patent Document 1, since the anti-slip means is only provided at the portion in contact with the pipe, it can be installed on the upper part of the pipe, but cannot be installed on the lower part or side surface of the pipe. In addition, although the magnetic level can be attached to a metal pipe, there is a problem that it cannot be used for a vinyl chloride pipe or the like.

In order to solve these problems, for example, as shown in FIG. 22, the gradient meter 200 is a plate-like member that is curved in a substantially arc shape along the circumferential direction of the pipe 101, and the inner diameter side surface of the pipe 101 is A fixing portion 201 that can match the axial length direction of the pipe 101 with the axial length direction of the pipe 101 by being pressed against the surface of the pipe 101 is provided, and a bubble tube 202 is provided on the outer peripheral surface of the fixing portion 201 (for example, Patent Document 2).
JP 2000-298018 A JP 2003-14454 A

  However, since the gradient meter 200 shown in Patent Document 2 is limited to the bubble tube 202 attached to the fixed portion 201, a commercially available level or the like used so far cannot be used, which is economically preferable. Absent. Moreover, since the shape of the bubble tube 202 which can be used is limited, when the bubble tube 202 is damaged, it is necessary to purchase the entire gradient meter 200 including the same bubble tube 202 or the fixing unit 201.

  The present invention has been made for the purpose of solving the various problems as described above, and a commercially available level can be easily and accurately attached to a pipe, and the slope of the pipe can be accurately adjusted. An object of the present invention is to provide a spirit level fixture that can be measured.

  According to the spirit level fixture of claim 1, since the pipe gripping portion is made of an elastic member having a substantially arc-shaped cross section that can be fitted on the outer periphery of the pipe, it cannot be attached with a conventional magnetic level. It can be accurately attached to a vinyl pipe or the like along the outer periphery of the pipe. Moreover, since the level attachment has a metal level plate for mounting the level, it is possible to use a commercially available level as it is. Is economical.

  Further, if a level attachment is attached to the pipe, it is not necessary to hold the level by hand, and the slope of the pipe can always be confirmed while working with both hands. Furthermore, when working on a stepladder, etc., it is possible to move to the next work area with the level attachment attached to the pipe, and it is not necessary to get off the stepladder to obtain a measuring instrument. Can be performed efficiently.

  Further, since the level mounting plate is formed in a substantially L shape, for example, when the ceiling pocket is narrow and there is no room for mounting the level on the upper surface of the pipe, a pipe gripping portion is provided on the side of the pipe. Can be used to accurately measure the gradient by placing a level on the other surface different from the mounting surface parallel to the longitudinal direction of the pipe gripping portion provided at the tip of the support portion. it can.

  According to the level attachment of Claim 3, the support part is provided so that it can expand and contract. Thereby, for example, in the case of measuring the slope of the pipe at a high position that does not reach a little by the height of a person with a pipe made of vinyl chloride provided near the ceiling, with the support portion extended in advance, By attaching a level attachment to the lower surface of the pipe, it is possible to easily magnetically attach a magnetic level to the level plate mounting plate without using a stepladder or the like. Furthermore, the trouble of using a stepladder or the like can be saved when reading the measured value of the level.

  According to the spirit level fixture of claim 4, the spirit level mounting plate is rotatably provided. As a result, by rotating the level mounting plate, the orientation of the level mounted on the level plate can be changed. Therefore, the level and verticality of the piping can be easily achieved with one level. Can be measured.

  According to the level attachment of the fifth aspect, the pipe gripping portion has guide portions provided at both ends in the outer peripheral direction so as to be opened outwardly in the longitudinal direction of the pipe gripping portion. As a result, when the pipe gripping part is attached to the pipe, the pipe is guided by the guide part, and the opening of the pipe gripping part is likely to spread along the outer peripheral surface of the pipe. Becomes easier. Further, since the pipe gripping part attached to the pipe can be removed by grasping the guide part, it is easy to remove from the pipe.

  According to the level attachment of the sixth aspect, since the slip preventing process is applied to the inner peripheral surface of the pipe gripping portion, the level attachment attached at a predetermined position of the pipe is not displaced.

  According to the spirit level fixture of claim 7, a plurality of wings having openings capable of sandwiching the pipe by being rotationally biased in the closing direction are provided on both ends in the longitudinal direction of the pipe fitting member. Yes. Accordingly, by covering the pipe with the wing, the level attachment is fixed to the pipe by the respective wings on both ends of the pipe fitting member in which the diameter of the outer periphery of the pipe matches the diameter of the opening of the wing. That is, it becomes possible to cope with pipes of various diameters.

  According to the spirit level fixture according to claim 8, since the knob part which makes the opening part of the wing expandable is provided, by using the knob part, the pipe of the spirit level fixture can be connected to the pipe. Attachment and removal are easy.

  According to the spirit level fixture according to claim 9, since the plurality of pipe gripping portions are connected to each other with a predetermined interval in the longitudinal direction by the connecting member, the gradient at the predetermined interval of the pipe is measured. And the accuracy of gradient measurement can be improved.

  According to the spirit level attachment according to claim 10, even if it is a commercially available non-magnetic level, the non-magnet level is clamped by the clamping means, on the metal level mounting plate, By magnetizing the level holder that holds the non-magnet level, the gradient of the pipe can be accurately measured.

  According to the level attachment of the eleventh aspect, the marks are provided on the outer peripheral surface of the pipe gripping portion at predetermined angular intervals. Thereby, for example, by providing a center line in the outer peripheral direction of the pipe gripping part and lines etc. that are marked at intervals of 1 degree on both sides of the outer peripheral direction from the central part, the pipe gripping part attached to the pipe from the position, When rotating along the outer periphery of the pipe, the number of rotations can be confirmed by using the line as a mark.

  According to the spirit level fixture of claim 12, the metal convex part formed in convex shape is provided in the longitudinal direction of the outer peripheral surface at predetermined intervals in the outer peripheral direction of the pipe gripping part. . Thereby, for example, by providing a convex part at the center part in the outer peripheral direction of the pipe gripping part and 90 degrees on both sides in the outer peripheral direction from the central part, it can be used as a mark when rotating along the outer periphery of the pipe. it can. Moreover, since the said convex part is metal, it is also possible to attach a magnet type level directly on this convex part.

  The best mode for carrying out the present invention will be described below with reference to the drawings. As shown in FIG. 1, the level attachment 1 according to the first embodiment includes a pipe gripping portion 3 made of an elastic member formed in an approximately circular arc shape that can be fitted on the outer periphery of the pipe 2, and the pipe. It comprises a support part 4 provided at the center in the circumferential direction of the grip part 3 and an L-shaped level device mounting plate 5 provided at the tip of the support part 4.

  When measuring the gradient of the pipe 2, the level used is to put alcohol etc. into the glass tube, leaving air bubbles so that the air bubbles come to the center when the pipe is horizontal. Things are common. Commercially available levels include a non-magnet level that does not have a magnet 13 and a magnetic level 14 that has a magnet 13 on the lower surface so that it can be magnetically attached to a metal pipe. In addition, a pipe 2 made of vinyl chloride is generally used for the pipe 2 in a detached house or the like. In this case, the magnetic level 14 cannot be magnetically attached to the pipe 2 as it is.

  The pipe gripping portion 3 is formed by bending a thin plate-like metal or synthetic resin member so that the cross section is substantially arc-shaped. In addition, since the pipe gripping portion 3 is made of an elastic member, by pressing the circumferential end portions 6 of the pipe gripping portion 3 against the outer peripheral surface of the pipe 2, the diameter of the circumferentially open side of the pipe gripping portion 3 is increased. The Furthermore, by pushing in the pipe gripping part 3, the pipe gripping part 3 embraces the pipe 2 and is fixed by an elastic action. In addition, the longitudinal direction of the pipe gripping portion 3 has a predetermined length that does not deviate even when a slight force is applied to the longitudinal direction when the pipe gripping portion 3 is attached to the pipe 2. The pipe gripping part 3 preferably covers more than half of the outer periphery of the pipe 2. As a result, the inner periphery of the pipe gripping portion 3 sandwiches a portion below the maximum diameter of the pipe 2, so that the pipe can be more stably attached. Moreover, the piping grip part 3 which concerns on this embodiment is an example, and the material used, a shape, etc. can be suitably changed according to the objective.

  In the level attachment 1a shown in FIG.2 and FIG.3, the guide part 7 provided in the outer opening over the elongate direction is formed in the circumferential direction both ends of the piping holding part 3. As shown in FIG. As a result, when the pipe gripping portion 3 is fitted into the pipe 2, the guide portion 7 becomes slippery while coming into contact with the outer peripheral surface of the pipe 2, so that the opening side in the circumferential direction of the pipe gripping portion 3 expands along the outer peripheral surface. This makes it easier to attach the pipe gripping part 3 to the pipe 2. Moreover, since the pipe gripping part 3 attached to the pipe 2 can be removed by grasping the guide part 7, the pipe 2 can be easily removed.

  Further, as shown in FIG. 4, the pipe gripping portion 3 attached to the pipe 2 is slipped from its predetermined position by slipping the inner peripheral surface of the pipe gripping portion 3 as shown in FIG. Therefore, it is possible to measure the gradient more accurately. The anti-slip process is more effective if irregularities are formed on the inner peripheral surface.

  Further, if a line Y serving as a mark is provided along the longitudinal direction at the central portion in the outer peripheral direction of the pipe gripping portion 3 and at 45 ° and 90 ° positions on both sides in the outer peripheral direction from the central portion, the pipe can be attached to the pipe 2 When the pipe gripping portion 3 is rotated from the position along the outer periphery of the pipe 2 by a predetermined angle, the line Y can be used as a mark, which is convenient. In addition, although the space | interval of the line Y is not specifically limited, It is preferable to provide in the location of 90 degree | times of the center part of the circumferential direction at least and the circumferential direction both sides.

  Furthermore, as shown in FIG. 4, by providing the line Z so as to be orthogonal to the line Y, the line Z can be rotated as a mark when the leveler mounting plate 5 is rotated 90 degrees. Thereby, for example, in order to measure the verticality of the pipe 2 provided substantially vertically, even when the leveler mounting plate 5 needs to be rotated 90 degrees, the level Z is rotated by using the line Z as a mark. Since positioning of the device mounting plate 5 is facilitated, the verticality of the pipe 2 can be measured more accurately. Further, if the pipe gripping portion 3 is made of metal as in the present embodiment, as shown in FIG. 4, it becomes possible to directly place the magnetic level 14 on the outer peripheral surface of the pipe gripping portion 3, Furthermore, by using the line Y as a mark, the magnetic level 14 can be accurately placed.

  One side of the support portion 4 is fixed to the central portion in the circumferential direction of the pipe gripping portion 3. . As shown in FIG. 3, in the support portion 4, a male threaded shaft portion 9 is screwed into a cylindrical body 8 engraved with a female screw provided on the outer periphery of the pipe gripping portion 3. The height can be adjusted by inserting and removing while rotating. At the time of measurement, the shaft portion 9 is fastened by the lock nut 10 to be fixed. In addition, the support part which concerns on this embodiment is an example, and it is also possible to apply another known method.

  In addition, by providing a screw hole or the like on the outer peripheral surface of the pipe gripping portion 3, it is possible to make the cylinder 8 detachable from the pipe gripping portion 3. Further, a plurality of screw holes may be provided at predetermined angular intervals in the outer peripheral direction of the pipe gripping portion 3. Thereby, since it becomes possible to attach a plurality of magnet type level 14 to one level attachment 1a by using a plurality of support parts 4 and level mounting plates 5, gradients in different directions are once applied. Can be confirmed.

  As shown in FIG. 1, the metal level plate mounting plate 5 is formed of a magnetized thin plate-like metal, and is substantially from the end of one surface 11 parallel to the longitudinal direction of the pipe gripping portion 3. It is configured in an L shape so as to stand vertically, and the magnet 13 of the magnetic level 14 can be attached to either of the surfaces 11 and 12. In addition, since the one surface 11 is provided at the tip of the shaft portion 9, if the lock nut 10 is loosened and the shaft portion 9 is rotated, the level plate mounting plate 5 is centered on the shaft portion 9. Can rotate. This makes it possible to change the orientation of the magnetic level 14 placed on the level mounting plate 5 as shown in FIG. The horizontality and verticality of the pipe 2 can be easily measured.

  In addition, as shown in FIG. 6, a level 14 is provided on the pipe 2 as in the case where the pipe 2 is provided supported by the pipe holder 16 from the ceiling 15 in a narrow space such as a ceiling pocket. If it is difficult to mount the pipe, the pipe gripping part 3 is attached to the side surface of the pipe 2 and the magnetic level 14 is mounted on the surface 12 of the L-shaped level mounting plate 5. The gradient of the pipe 2 can be measured. 1 to 6, the magnetic level 14 is used. However, when the slope of the pipe 2 is gentle, a commercially available non-magnetic level is simply mounted on the level mounting plate 5. It's okay.

  FIG. 7 is an example in which the pipe gripping portion 3 is attached to the lower side of the pipe 2 supported by the pipe holder 16 at a high position such as near the ceiling 15, and the magnetic level 14 is attached to the level mounting plate 5. By magnetizing on the surface 11, the gradient of the pipe 2 can be measured. If the pipe 2 is supported from the ceiling 15 that is slightly higher than the height of a person, the slope of the pipe 2 is confirmed without using a stepladder by extending the shaft portion 9 of the support portion 4. Therefore, workability can be improved.

  As shown in FIG. 8, the pipe gripping part 3 a of the level attachment 1 b according to the second embodiment is a pipe fitting member made of an elastic member formed in an approximately circular arc shape that can be fitted around the outer periphery of the pipe 2. A plurality of wings 19 having different diameters of the openings 18 are respectively provided at both ends in the longitudinal direction of 17. As shown in FIG. 9, the wing 19 has two sandwiching members 20 having a substantially arc-shaped cross section, and a plate spring 21 on the upper surface of one end on the circumferential side where the two sandwiching members 20 are in contact with each other. Thus, the connected members.

  The leaf springs 21 have a function of rotating and biasing the respective clamping members 20 in the closing direction, and as shown in FIG. 9B, the portions connected by the leaf springs 21 are used as fulcrums. By opening the holding member 20 outward, the opening 18 is enlarged and a biasing force is applied in the closing direction. Here, the leaf spring 21 is used as the biasing means, but the present invention is not limited to this, and other well-known biasing means such as a torsion coil spring can be used.

  Further, as shown in FIG. 8, the pin insertion ports 22 provided in the respective leaf springs 21 of the plurality of wings 19 having different diameters of the openings 18 and both ends of the pipe fitting member 17 in the longitudinal direction are provided. The pin 24 is inserted and fixed in the pin insertion port 23. As a result, as shown in FIG. 10, a plurality of wings 19 are provided at both ends of the pipe fitting member 17 in the longitudinal direction. The number of wings 19 is not limited to two, and one or three or more may be provided.

  Therefore, for example, as shown in FIG. 10, even when attaching to a thin pipe 2a, the level attachment 1b is connected to the pipe 2a by the wing 19a having the diameter of the opening 18 that matches the diameter of the outer periphery of the pipe 2a. Fixed to. That is, by providing a plurality of wings 19 having different radii of the opening 18, it is possible to attach to pipes having various diameters.

  On the other hand, as shown in FIG. 11, when fixed to a pipe 2b having an outer diameter larger than that of the pipe 2a of FIG. 10, the level is attached by a wing 19b having an opening 18 that matches the outer diameter of the pipe 2b. The tool 1b is fixed. In this case, the wing 19a having the opening 18 smaller in diameter than the wing 19b is in a state where the two clamping members 20 are flipped up to the left and right.

  Further, in order to reduce the state in which the pinching member 20 of the wing 19a is greatly bounced up, as in the wing 19c shown in FIG. 12, the radial direction in the vicinity of the connecting portion by the leaf springs 19 of the two pinching members 20a The thickness may be reduced. As a result, as shown in FIG. 12 (b), the right and left jumping of the two clamping members 20a can be reduced, so that the urging force in the closing direction by the leaf spring 21 is also reduced, so that Easy to install.

  Moreover, as shown in FIG. 13, you may provide the knob part 25 in the vicinity of the one end of the connection side of the two clamping members 20, respectively. By pinching the knob portion 25 in the direction approaching each other, as shown in FIG. 13B, the opening 18 of the wing 19d is enlarged, so that the level attachment 1b can be removed from the pipe 2a and the like. It becomes easy.

  FIG. 14 shows an example of the vicinity of the connecting portion of the holding member 20. A spring 27, which has a biasing force in the closing direction, is attached to the protruding portion 26 formed on one holding member 20, and the other holding member 20 is attached to the other holding member 20. By inserting the protrusions 26 into the formed connection holes 28, the holding members 20 are connected to each other, and springs 27 that act as a biasing force in the closing direction are provided between the holding members 20. Then, by attaching both ends of the spring 27 to the inner peripheral surface of each clamping member 20, the urging force of the spring 27 acts, so that the wing 19d can clamp the pipe 2a and the like.

  As shown in FIG. 15, the level attachment 1 c according to the third embodiment has two pipe gripping portions 3 and a substantially central portion in the circumferential direction of the two pipe gripping portions 3 respectively in the longitudinal direction. The connecting member 29 includes a connecting member 29 that is connected with an interval, a support portion 4 that is provided at the center in the longitudinal direction of the connecting member 29, and a level mounting plate 5 that is provided at the tip of the supporting portion 4.
