DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS.
As shown in FIGS. 1 and 2, the gas meter support device 1 according to the present invention includes a device main body 10 and a pair of connecting pipes 20 and 30 as main components.
[0012]
The apparatus main body 10 includes a fixed plate (fixed portion) 11 and a movable plate (movable portion) 12.
As shown in FIGS. 3 and 4, the fixing plate 11 is formed by forming a metal flat plate, and extends upward and downward from an upper vertical plate portion 11 a extending vertically and from a lower end portion of the upper vertical plate portion 11 a. It is composed of a horizontally extending horizontal plate portion 11b and a lower vertical plate portion 11c formed by cutting the upper vertical plate portion 11a into a “U” shape and bending the portion following the rear end of the horizontal plate portion 11b by 180 °. ing. The upper vertical plate portion 11a and the lower vertical plate portion 11c are located on the same plane, and both are fixed to the vertical wall portion W by screws 13 as shown in FIGS. The horizontal flat plate portion 11b is formed with a pair of long holes 11d and 11d extending in the front-rear direction in parallel with each other.
[0013]
As shown in FIGS. 3 and 5, the movable plate 12 is made of a metal flat plate, and is placed on the horizontal plate portion 11b so as to be movable in the front-rear direction. Bending portions 12 a projecting downward are formed on the left and right side portions and the front side portion of the movable plate 12. Thereby, the movable plate 12 is reinforced. Moreover, as shown in FIG. 3B, the distance between the bent portions 12a 'and 12a' located on the rear end side of the movable plate 12 among the bent portions 12a and 12a formed on the left and right side portions is as follows. The horizontal plate portion 11b has substantially the same size as the width in the left-right direction. Therefore, when the movable plate 12 is moved in the front-rear direction, the bent portions 12a ′ and 12a ′ come into contact with the side surface of the horizontal plate portion 11b to guide the movement of the movable plate 12 in the front-rear direction.
[0014]
Further, insertion holes 12b and 12b are formed in the rear end portion of the movable plate 12 at locations facing the long holes 11d and 11d, respectively. The threaded portion 41a of the bolt 41 is inserted into the insertion hole 12b from above. The screw portion 41a passes through the insertion hole 12b and the long hole 11d and protrudes downward from the horizontal plate portion 11b, and a nut 42 is screwed there. And the bolt 41 and the nut 42 are fastened, and the movable plate 12 is fixed to the horizontal plate portion 11b by sandwiching the horizontal plate portion 11b and the movable plate portion 12 between the head portion 41b and the nut 42 of the bolt 41. .
The desirable shape and structure of the nut 42 will be described later.
[0015]
A pair of mounting grooves 12c and 12d extending rearward are formed on the left and right sides of the front surface of the movable plate 12, respectively. The end on the back side of each mounting groove 12c, 12d has a substantially semicircular shape. In addition, a pair of guide holes 12e and 12f penetrating the movable plate 12 are formed on the left and right sides of the movable plate 12. Each guide hole 12e, 12f extends in a substantially arc shape with the center of curvature at the end on the back side of the mounting grooves 12c, 12d as the center, each front end faces forward, and each rear end is left and right. It faces each direction outside. Further, the movable plate 12 is formed with stop holes 12g and 12h extending forward from the guide holes 12e and 12f, respectively, and holes 12i and 12j are formed at the front ends of the stop holes 12g and 12h. The widths of the stop holes 12g and 12 are narrower than the widths of the guide grooves 12e and 12f, and the inner diameters of the holes 12i and 12j are substantially the same as the widths of the guide holes 12e and 12f.
[0016]
As shown in FIGS. 1 and 2, the connecting tube 20 is formed by bending a tube having a circular cross section into a substantially “U” shape, and is disposed on the movable plate 12 with both ends directed downward. ing. One end 20a of the connecting pipe 20 is inserted into the mounting groove 12c so as to be movable in the front-rear direction and to be rotatable. In addition, a fixed arm 21 that extends along the upper surface of the movable plate 12 is formed in the connection pipe 20. An insertion hole (not shown) is formed at the tip of the fixed arm 21 at a location facing the guide hole 12e. A threaded portion (not shown) of the bolt 51 is inserted into the insertion hole from above, and the threaded portion of the bolt 51 penetrates the insertion hole and the guide hole 12e and protrudes downward. A nut (not shown) is screwed to the lower end portion of the threaded portion of the bolt 51 protruding downward from the guide hole 12e. The connecting pipe 20 is fixed to the movable plate 12 by tightening the bolt 51 and the nut.
[0017]
The threaded portion of the bolt 51 can move in the longitudinal direction with respect to the guide hole 12e, but cannot be inserted into the retaining hole 12g because the outer diameter of the threaded portion is larger than the width of the retaining hole 12g. ing. Therefore, the connecting pipe 20 can be rotated until the screw portion of the bolt 51 hits the front and rear ends of the guide hole 12e, and when the screw tube of the bolt 51 hits the rear end of the guide hole 12e, When the one end portion 20a and the other end portion 20b of the connecting pipe 20 are located at the unfolded position aligned in the left and right direction and turn until the threaded portion of the bolt 51 hits the front end portion of the guide hole 12e, both end portions 20a and 20b are moved in the front-rear direction. Located in a parallel position. Further, when the bolt 51 is pulled out from the guide hole 12e in a state where the connecting pipe 20 is rotated to the parallel position, the connecting pipe 20 can move forward along the mounting groove 12 while maintaining the posture at the parallel position. There, when moving the connection pipe 20 prior to the parallel position the insertion hole facing the hole 12i, by screwing the nut by inserting bolts 51 into the insertion hole and the hole 12i, it can be fixed at that position .
[0018]
Similarly to the connecting tube 20, the connecting tube 30 is substantially U-shaped and has a fixed arm 31. And while being able to rotate between a deployment position and a parallel position, it can move to a front parallel position from a parallel position. Moreover, the bolt 51 and the nut can be fixed at an arbitrary position between the deployed position and the parallel position and the front parallel position.
[0019]
The inlet port M ₁ and the outlet port M ₂ of the gas meter M are connected and fixed to the one end portions 20 a and 30 a of the connecting pipes 20 and 30 by nuts N ₁ and N ₂ , respectively. Therefore, the gas meter M is supported by the apparatus main body 10 via the connection pipes 20 and 30, and is thus supported by the wall portion W. One end portions of gas pipes G ₁ and G ₂ made of a flexible gas pipe, an iron pipe, and the like are connected to the other end portions 20b and 30b of the connection pipes 20 and 30, respectively. The other end of the gas G ₁ is connected to the gas pipe of main tap side (not shown). The other end of the gas pipe G ₂ is is SEZZ the gas pipe of household (not shown). Accordingly, gas is introduced from the gas pipe G ₁ to the gas meter M through the connection pipe 20 and the amount of use is measured. Then, gas which has passed through the gas meter M is provided to the home gas appliances via the connecting pipe 30 and gas pipe G _2.
The connecting pipe 20 is provided with a gas stopper 22 having a well-known structure. By opening and closing the gas stopper 22, the gas is supplied and stopped.
[0020]
In the gas meter support device 1 configured as described above, when the connecting pipes 20 and 30 are rotated to the deployed position, the movable plate 12 is moved forward or backward when the water pipe (not shown) becomes an obstacle. Therefore, water pipes can be avoided. In addition, when the connecting pipes 20 and 30 are positioned at the parallel positions and the other end portions 20b and 30b hit the wall portion W, the movable plate 12 is prevented from hitting by moving forward. can do. Therefore, the support apparatus 1 can be arrange | positioned in a desired location. And since it can respond to the various states of an installation location with the one support apparatus 1, it is not necessary to prepare the thing of various dimensions according to an installation location beforehand. Therefore, the manufacturing cost and management cost of the support device 1 can be reduced.
[0021]
Next, a desirable form of the nut 42 for fixing the movable plate 12 to the horizontal plate portion 11b will be described. The nut 42 can also be used as a nut that is screwed into the bolt 51.
As shown in FIGS. 6 to 8, a pair of insertion portions 42 b and 42 b are erected on the upper surface of the nut 42. The pair of insertion portions 42b and 42b are disposed so as to be separated from each other in the longitudinal direction (front-rear direction) of the long hole 11d and to face each other with the screw hole 42a therebetween. The width of the insertion part 42b is narrower than the width of the long hole 11d. Therefore, the insertion portions 42b and 42b can be inserted into the long hole 11d from below and can move in the longitudinal direction in the long hole 11d. Moreover, the height of the insertion part 42b is larger than the thickness of the horizontal plate part 11b. Therefore, when the insertion portion 42b is inserted into the long hole 11d until the upper surface of the nut 42 comes into contact with the lower surface of the horizontal plate portion 11b, the upper end portion of the insertion portion 42b protrudes upward from the upper surface of the horizontal plate portion 11b.
[0022]
In order to prevent the upper end portion of the insertion portion 42b protruding upward from the horizontal plate portion 11b and the locking portion 42c described later from striking the movable plate 12, the portion surrounding the insertion hole 12b of the movable plate 12 is upward. The upper end portion of the insertion portion 42b and the locking portion 42c enter the space below the bulging portion 12k.
[0023]
The pair of insertion portions 42b and 42b are arranged on a circumference centered on the screw hole 42a. Moreover, the radius of curvature of the inner surface of the insertion portion 42b is larger than the outer diameter of the screw portion 41a so that the screw portion 41a of the bolt 41 can be inserted between the insertion portions 42b and 42b. In this example, the width of the long hole 11d is almost the same. On the other hand, the curvature radius of the outer surface of the insertion portion 42b is larger than the width of the long hole 11d. Therefore, when the nut 42 is rotated in a state where the insertion portions 42b and 42b are inserted through the long holes 11d, the side surfaces of the insertion portions 42b and 42b abut against the side surfaces of the long holes 11d. As a result, the rotation of the nut 42 is prevented.
[0024]
A pair of locking portions 42c and 42c are formed between one side surface of the upper end portions of the pair of insertion portions 42b and 42b and between the other side surfaces so as to span between them. The locking portion 42c has an inner surface and an outer surface that have the same center of curvature and the same radius of curvature as the inner surface and the outer surface of the insertion portion 42b. Therefore, each upper end part of a pair of insertion part 42b, 42b and a pair of latching | locking part 42c, 42c are cyclic | annular as a whole. This is to improve the strength of the insertion portion 42b and the locking portion 42c. Further, since the radius of curvature of the outer surface of the locking portion 42c is the same as the radius of curvature of the outer surface of the insertion portion 42b and is larger than the width of the long hole 11d, the central portions of the locking portions 42c and 42c are on both side surfaces of the long hole 11d. Protrudes left and right. Accordingly, the locking portions 42c and 42c can be placed on the upper surface of the horizontal plate portion 11b, and thereby the nut 42 is mounted on the horizontal plate portion 11b in a locked state.
[0025]
Here, since the radius of curvature of the outer surfaces of the locking portions 42c and 42c is larger than the width of the long hole 11d, the locking portions 42c and 42c cannot be simply inserted into the long hole 11d from below. Therefore, the locking portions 42c and 42c are inserted between the width of the insertion portion 42b and the upper surface of the nut 42 and the lower surface of the locking portion 42c so that they can be inserted into the long hole 11d as shown in FIG. The distance and the radius of curvature of the outer surface of the locking portion 42c are determined.
[0026]
That is, in order to insert the locking portions 42c and 42c into the long hole 11d from below, first, as shown in FIG. 9A, one locking portion 42c is positioned above the other locking portion 42c. In such a manner, the nut 42 is inclined. By moving the nut 42 obliquely upward in this state, one side wall portion that forms one side surface of the long hole 11 d is inserted between the one locking portion 42 c and the upper surface of the nut 42. As shown in FIG. 9B, when the side surfaces of the insertion portions 42b and 42b are inserted until they substantially come into contact with one side surface of the long hole 11d, the other locking portion 42c is positioned inside the other side surface of the long hole 11d. Thus, the other locking portion 42c can be inserted into the long hole 11d from below. Therefore, the portion located below the nut 42 is moved upward, and the other locking portion 42c is inserted into the long hole 11d as shown in FIG. 9C. Thereafter, when the nut 42 is moved until the axis thereof reaches the central portion in the width direction of the long hole 11d, as shown in FIG. 9D, the central portions of the locking portions 42c and 42c become the long holes 11d. It faces the upper surface of the adjacent horizontal plate portion 11b and is placed thereon.
[0027]
When the nut 42 configured as described above is used, the nut 42 can be non-rotatably mounted in the long hole 11d of the horizontal plate portion 11b. Therefore, when the bolt 41 is screwed into the nut 42, And when tightening, it is not necessary to hold the nut 42 by hand. Therefore, the bolt 41 can be easily screwed onto the nut 42, and as a result, the movable plate 12 can be easily fixed to the fixed plate 11. In particular, after fixing the fixing plate 11 to the wall portion W and connecting the gas pipes F ₁ and F ₂ and the gas meter M to the connecting pipes 20 and 30, it is difficult to put a hand under the horizontal plate portion 11b. Therefore, the effect is very large.
[0028]
In addition, this invention is not limited to said embodiment, It can change suitably.
For example, in the above-described embodiment, the movable plate 12 can be adjusted in the front-rear direction with respect to the fixed plate 11, but may be adjustable in the left-right direction, or may be adjusted in the front-rear direction and the left-right direction. It may be. When a normal nut is used instead of the nut 42, an insertion hole may be formed in the horizontal plate portion 11c and a long hole may be formed in the movable plate 12.
[0029]
【The invention's effect】
As described above, according to the inventions according to claims 1 to 6, when the water pipe or the unevenness of the wall part interferes with the installation of the support device, particularly when it hits the connecting pipe. By moving the movable part and adjusting its position, it is possible to avoid obstructing or colliding. Therefore, a support apparatus can be installed in a desired location. And since it can respond to various cases with one support apparatus, the effect that the manufacturing cost and management cost of a support apparatus can be reduced is acquired.
In particular, according to the fifth aspect of the present invention, the bolt can be easily screwed into the nut after the position adjustment, and as a result, the movable portion can be easily fixed to the fixed portion.
According to the sixth aspect of the invention, since the movable portion is guided in the moving direction by the guide portion, when the insertion hole and the long hole through which the bolt is inserted are formed in the fixed portion and the movable portion. The effect that these positions can be prevented from shifting in a direction perpendicular to the longitudinal direction of the long hole is obtained.
