Description

  The present invention relates to a long piping material protective cover composed of a base and a lid that are assembled to each other to form a pipe material accommodating portion that accommodates a pipe material therein, and the base.

  A conventional base that forms a piping material protective cover (hereinafter sometimes simply referred to as “protective cover”) with a long lid presses the pipe material from both sides against the base body fixed to the wall surface. Thus, the pair of wall portions to be held are erected. In addition, the pipe material may not be pressed firmly by the pair of wall portions due to mutual manufacturing errors of the pipe material and the protective cover. In addition, in order to hold a plurality of pipe materials having different nominal diameters (outer diameters) in which the diameter of the pipe material is defined by a standard such as JIS, with the pair of wall portions of the base, the pair of wall portions is greatly directed outward. Although it is necessary to bend, each wall is formed in a curved shape, so that the deformation amount of each wall has a certain limit, and each wall is When it is greatly bent and deformed, the load on the wall surface or the like that fixes the base also increases.

  Therefore, since the base that constitutes the conventional protective cover can hold only one type of pipe material having a specific outer diameter, when the outer diameter of the pipe material changes in the middle of the piping path, A protective cover having a size corresponding to the diameter had to be used. For this reason, when the outer diameter of the pipe material changes in the middle of the piping path, the size of the protective cover also changes, which impairs the aesthetic appearance. In addition, in the case of the conventional protective cover base, when the outer diameter of the pipe material to be held changes, the pipe cores of the pipe materials having different outer diameters may be displaced, so that they may be connected via different diameter connectors. was difficult.

  In addition, when two types of pipe materials having different nominal diameters are accommodated using a protective cover of the same size, as described in Patent Document 1, a pair of side wall portions constituting the base are separately provided. However, the protective cover has the same size and can be used with multiple types of protective covers that can hold pipes with different diameters. It is necessary to prepare and store the same number of spacers, which is troublesome not only in actual construction but also in management and the like.

Moreover, even if the nominal diameter is the same, the outer diameter is different between the hard vinyl chloride pipe and the cross-linked polyethylene pipe, so it could not be protected by the common protective cover.

  It is an object of the present invention to accommodate and protect a plurality of types of pipe materials having different outer diameters with the same pipe material protective cover.

The invention of claim 1 for solving the above-mentioned problem is a long piping material protective cover comprising a base and a lid body, which are assembled to each other to form a pipe material accommodating portion for accommodating a pipe material therein, The base is provided with a tube material storage portion in which an opening is formed so that at least two types of tube materials having different outer diameters can be stored and held, and the tube material storage portion is stored in order to form the tube material storage portion. A pair of outer wall portions disposed opposite to both sides of the pipe member to be disposed, and disposed opposite to each other with a predetermined gap inside the pair of outer wall portions, and one end portion in a cross-sectional view is the opening It is connected to the outer wall portion via a connecting portion on the side of the portion, and the other end portion is extended to the opposite side of the opening portion to be a free end portion, and is elastically restored by its own deformation. Push the outer peripheral surface of the pipe material stored in the pipe material storage part from both sides. Consists, a pair of inner wall portions to maintain the housing orientation of the tubing to flex deformed outwardly to cooperate in response to the outer diameter of the tube to the pair of outer wall portions and a pair of inner wall portions to accommodate The tubular material is accommodated and held in the tubular material accommodating portion.

  According to the first aspect of the present invention, when the tube material is pushed in from the opening of the base toward the housing, the outer wall is deformed so that the opening is expanded, and the inner wall is opposite to the opening. Since the free end portion is deformed so as to expand, the tubular material accommodated in the tubular material accommodating portion is held by an elastic restoring force that causes the outer wall portion and the inner wall portion to be restored to the original shape. That is, the tubular material accommodated in the tubular material accommodating portion is pressed on the opening side of the tubular material by the elastic restoring force of the outer wall portion, and on the side opposite to the opening of the tubular material (the free end side of the inner wall portion) by the elastic restoring force of the inner wall portion. ) Is pressed, different portions along the pushing direction of the tube material are pressed and held by the elastic restoring forces of the outer wall portion and the inner wall portion, respectively. For this reason, the holding state of the pipe material accommodated in the pipe material accommodating part of the base is stabilized.

  Thus, although the pipe material accommodated in the pipe material accommodating part of a base is hold | maintained by the cooperative action of each elastic restoring force of an outer wall part and an inner wall part, two types of pipe materials from which an outer diameter differs are accommodated. Considering the case, the smaller the outer diameter of the pipe material, the larger the inner wall portion is deformed than the outer wall portion, and the elastic restoring force of the inner wall portion is mainly used to hold the pipe material. On the contrary, the larger the outer diameter of the pipe material, the larger the outer wall part is deformed than the inner wall part, and the elastic restoring force of the outer wall part becomes a main component to hold the pipe material. In addition, when the pipe material having the minimum outer diameter is accommodated in two or more types of pipe materials that can be accommodated, the inner wall portion and the outer wall portion are not deformed at all, that is, after the tube material is completely accommodated in the tube material accommodation portion, There is a possibility that the tube material is held by the shape of the inner wall portion without deforming the portion and the outer wall portion at all.

  Thus, the ratio of each deformation amount of the outer wall portion and the inner wall portion constituting the tube material housing portion of the base changes as described above corresponding to the outer diameter of the tube material pushed inward from the opening portion. Therefore, in other words, the outer wall portion and the inner wall portion are deformed by an amount corresponding to the outer diameter of the tube material pushed inward from the opening portion, so that the outer diameter is larger than the distance between the pair of inner wall portions. If it is a tube material having, it is possible to hold a plurality of types of tube materials having different outer diameters. In addition, the pipe material held in the pipe material storage portion is held in a hollow arrangement state between a pair of inner wall portions that always face each other regardless of the outer diameter thereof, and the pipe material is held like a conventional protective cover. This is greatly different from the configuration in which the base bottom wall is pressed and held. For this reason, when pipes with different diameters are accommodated in the same protective cover, the misalignment of both pipes is reduced, and when connecting pipes with different diameters with connectors, it is necessary to excessively deform the pipe ends. Disappears.

  Therefore, according to the first aspect of the present invention, it is possible to flexibly hold pipe materials having different outer diameters in the case of dimensional errors, different nominal diameters, the same nominal diameter, the same material, or the like.

Further, the invention of claim 2 is a long piping material protective cover comprising a base and a lid that are assembled together to form a pipe material accommodating portion for accommodating the pipe material therein, In order to be able to accommodate and hold at least two types of tube materials having different diameters, the tube material accommodating portion is formed with an opening, and the tube material accommodating portions are arranged on both sides of the accommodated tube material to form the tube material accommodating portion. A pair of outer wall portions disposed opposite to each other, and disposed opposite to each other with a predetermined gap inside the pair of outer wall portions, and one end portion in a cross-sectional view is located on the opening portion side. The other end portion is connected to the outer wall portion via a connecting portion, and is extended to the opposite side of the opening portion to be a free end portion. Tubing accommodation by pressing the outer peripheral surface of the contained tubing from both sides A pair of inner wall portions to maintain, consists, when accommodating held in the tube material container tubing of minimum outer diameter of the at least two different tube outer diameters, the inner wall does not flexural deformation When the inner surface of the inner wall portion is in close contact with the outer peripheral surface of the minimum outer diameter tube material, and the tube material larger in diameter than the minimum outer diameter tube material is stored and held in the tube material storage portion The pair of outer wall portions and the pair of inner wall portions are flexibly deformed in cooperation with the outer diameter of the tube material, and the large-diameter tube material is accommodated and held in the tube material accommodating portion .

The invention of claim 2 grasps only the critical part of the invention of claim 1. That is, the invention of claim 1 states that “the pair of outer wall portions and the pair of inner wall portions cooperate to correspond to the outer diameter of the tube material and bend and deform outward, and the tube material is accommodated and held in the tube material accommodation portion. In addition to the requirement, the invention of claim 2 further includes “the minimum outside of at least two types of tube materials having different outer diameters that can be accommodated and retained in the tube material accommodating portion”. When the tubular material having a diameter is accommodated and held in the tubular material accommodating portion, the pair of inner wall portions and the pair of outer wall portions are both kept in an original shape without being deformed, and the minimum outer diameter tubular material is a pair. It is also a requirement that it is in close contact with almost the entire inner wall portion. In other words, in the invention of claim 2, the tube material having the smallest outer diameter among the at least two types of tube materials having different outer diameters that can be accommodated and retained in the tube material accommodating portion is retained by the original shape itself of the pair of inner wall portions. This is different from the invention of claim 1.

  According to a third aspect of the present invention, in the first or second aspect of the invention, the deformation base point of the deflection deformation of the inner wall portion is on the opening side, and the deformation base point of the outer wall portion is opposite to the deformation base point of the inner wall portion. It exists in the opening part side, It is characterized.

  According to the invention of claim 3, since the deformation base point of the inner wall portion is displaced in the deflection direction of the outer wall portion when the outer wall portion is bent and deformed, the displacement amount of the inner wall portion with respect to the absolute space is determined by the deflection deformation of the outer wall portion. The sum of the displacement amount of the deformation base point of the inner wall portion and the deflection amount of the inner wall portion with respect to the outer wall portion increases the displacement amount of the inner wall portion with respect to the original position. For this reason, the range of the outer diameter of the tube material that can be accommodated in the tube material accommodating portion of the base is widened (the difference between the maximum outer diameter and the minimum outer diameter of the tube material that can be accommodated in the tube material accommodating portion of the base is increased).

  According to a fourth aspect of the present invention, in any one of the first to third aspects of the present invention, at least the deformation base point of the inner wall portion is formed thinner than the other portions.

  According to the invention of claim 4, since the inner wall portion is easily deformed, when the tube material having a large outer diameter among the tube materials that can be accommodated is accommodated in the tube material accommodation portion, the pushing force of the tube material against the tube material accommodation portion is small. Therefore, the tube material can be accommodated easily.

  The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein the base includes a base body portion having a fixing portion to a wall surface or the like and forms a bottom wall portion of the pipe material housing portion. In this way, the pair of outer wall portions are integrally provided upright from both end portions in the width direction of the base body portion.

  According to the fifth aspect of the present invention, since the pair of outer wall portions are integrally provided on the base body portion, and the deformation base point of the outer wall portion is integral with the base body portion, the pipe material is accommodated. When the tube material is pushed into the portion and accommodated, the tube material can be pushed in stably.

Further, the invention of claim 6 is a long piping material protective cover comprising a base and a lid that are assembled together to form a pipe material accommodating portion for accommodating the pipe material therein, and the base comprises a pipe material A pair of outer wall portions disposed opposite to both sides of the accommodated tube material to form the tubular material accommodation portion. And one end portion side in a cross-sectional view is connected to the outer wall portion on the side of the opening portion via a connecting portion. The other end is extended to the opposite side of the opening to be a free end, and faces the outer peripheral surface of the tube accommodated in the tube accommodating portion by an elastic restoring force due to its own deformation. a pair of inner wall portions to hold the tubing in contact from both sides, is composed of The deformed bending outwardly by a pair of outer wall portions and a pair of inner wall portions cooperate, are characterized in that they contain hold the tube in the tube housing unit.

  According to the invention of claim 6, even when there is a slight dimensional error due to a manufacturing error or the like in the pipe, the pipe housed in the pipe material housing part has the pair of outer wall parts and the pair of inner wall parts in cooperation. Since the pipe is bent and deformed outwardly and stored and held in the pipe material storage portion, the pipe is stored and held in exactly the same manner as a normal size pipe material having no dimensional error.

  The invention according to claim 7 is a base of a piping material protective cover that forms a pipe material housing portion that accommodates a pipe material therein by being assembled with a long lid, and the base is long. A base body portion formed on both sides of the tube material to be formed so as to form a base body portion having a fixing portion to a wall surface and the like, and a tube material housing portion having the base body portion as a bottom wall portion. A pair of outer wall portions that are erected from each other, and are connected to the distal end side of each outer wall portion via a connecting portion so as to be disposed inside each outer wall portion, and are accommodated in a tube material accommodating portion. And a pair of inner wall portions that press and hold the tubular material from both sides by elastic deformation force, and one end portion of each inner wall portion in a sectional view forms an opening so that the tubular material can be accommodated in the accommodating portion. The other end portion is a free end portion, and extends toward the base body portion along the outer wall portion. The pipe material is accommodated and held in the pipe material accommodating part by deforming and deforming in cooperation with the outer diameter of the pipe material accommodated by the pair of outer wall parts and the pair of inner wall parts. Yes.

  The invention of claim 7 grasps the invention of claim 5 that cites claim 1 from the viewpoint of a base that constitutes the piping material protective cover, and substantially cites claim 1. The effect similar to that of the invention of claim 5 is exerted.

  The base housing part constituting the piping material protective cover of the present invention includes a pair of outer wall parts disposed opposite to both sides of the pipe material to be accommodated to form the pipe material housing part, and the pair of outer walls. One end in a cross-sectional view is connected to the outer wall on the side of the opening via a connecting portion, and the other end is It is extended to the opposite side of the opening to be a free end, and the tubular material is accommodated by pressing the outer peripheral surface of the tubular material accommodated in the tubular material accommodating part from both sides by elastic restoring force due to its own deformation. The inner wall portion to be maintained and the pair of outer wall portions and the pair of inner wall portions bend and deform separately according to the outer diameter of the pipe material to be accommodated. The tube material can be accommodated and protected.

  Hereinafter, the present invention will be described in more detail with reference to a plurality of examples.

First, with reference to FIGS. 1 and 2, it will be described the piping material protective cover K ₁ of the first embodiment. FIG. 1 is an exploded perspective view of the protective cover K ₁ , and FIG. 2 is a cross-sectional view of the base V ₁ . The protective cover K ₁ is long and includes a base V ₁ and a lid L ₁ that are assembled together to form a tube material storage portion that stores a tube material therein.

As shown in FIG. 2, the base V ₁ stands on a base main body 1 that is fixed in close contact with a wall surface, and a part slightly inward of both ends in the width direction of the base main body 1. A pair of outer wall portions W _{1 provided} and the upper end portions of the pair of outer wall portions W ₁ are connected via a connecting plate portion 2 and arranged at predetermined intervals inside the pair of outer wall portions W _1. and a pair of inner wall portions W ₂ is. Base main body portion 1, with both ends in the width direction is an adhesion portion 1a in close contact with the wall surface or the like, the portion occupying a central majority of the width direction, the tube material container by a pair of inner wall portions W ₂ 3 is a bottom wall portion 1b that is connected to the contact portion 1a by an inclined connection portion 1c and is formed in a stepped shape so as not to be in close contact with a wall surface or the like. When the base V ₁ is fixed to a wall surface or the like via a screw (not shown) at the inner side of the bottom wall portion 1b (on the tube material storage portion 3 side) and in the center in the width direction. A positioning groove 4 having a V-shaped cross section for positioning the screw is formed over the entire length. The wide groove formed on the back surface of the base body 1 and the narrow groove formed on both sides of the wide groove are interposed between the base body 1 and the wall surface as necessary. The fitting grooves 1d and 1e of the spacer (not shown) to be made are shown.

Next, with reference to FIG. 2, it will be described in detail the outer wall section W ₁ and the inner wall section W ₂ to form a tubular member accommodating portion 3. Standing plate portions 5 are erected vertically at both ends in the width direction of the bottom wall portion 1b of the base body portion 1 and are inclined outward at the upper end portion of the standing plate portion 5. The inclined plate portion 6 is integrally formed, and the outer wall main body portion 7 is integrally connected to the oblique upper end portion of the inclined plate portion 6. In Example 1, a pair of the outer wall W ₁ and a pair of inner wall portion W _2, when accommodating holding tubing P ₁ of minimum outer diameter (D ₁₎ is dimensioned so as not deformed at all . Then, when the outer wall body portion 7 and the inner wall main body portion 8 of the pair of inner wall portions W ₂ of the pair of the outer wall W ₁ are both accommodating retaining the cylindrical tube P ₁ of the smallest outer diameter, tube material P ₁ It is formed in an arc plate shape as present respective radially different on each circumference of the axis C _1. In other words, each arc center C ₀ of the outer wall main body portion 7 of the pair of outer wall portions W ₁ and the inner wall main body portion 8 of the pair of inner wall portions W ₂ is when the cylindrical pipe material P ₁ having the smallest outer diameter is accommodated and held. It coincides with the axis C ₁ of the tube member P _1. Here, the radii of the inner peripheral surfaces of the pair of outer wall main body portions 7 and the pair of inner wall main body portions 8 each having an arc plate shape centered on the arc center C ₀ are R ₁ and R ₂ , respectively, and the outer wall portion W _1. If the wall thickness (plate thickness) T ₁ of the inner wall portion W ₂ is the same, the distance between the outer wall main body portion 7 and the inner wall main body portion 8 is (R ₁ -R ₂ ), and the outer wall has an arc plate shape. The main body part 7 and the inner wall main body part 8 are arranged in parallel to each other. A space portion between the outer wall portion W ₁ and the inner wall portion W ₂ is a bending deformation space 10 for enabling the inner wall portion W ₂ to be bent and deformed. Further, in a portion that intersects the outer wall body portion 7 the arc center C ₀ parallel to the base bottom portion 1b of the main body 1 through the straight line N on the inner peripheral surface of, easily deformation of the outer wall body portion 7 An easily deformable groove 9 is formed over the entire length.

Further, the inner wall portion W ₂ includes an inner wall main body portion 8 and a vertical plate portion 11 extending substantially perpendicular to the bottom wall portion 1 b of the base main body portion 1 at the upper end portion of the inner wall main body portion 8. Composed. The upper end portion of the outer wall main body portion 7 constituting the outer wall portion W ₁ and the vertical plate portion 11 constituting the inner wall portion W ₂ are the connecting plate portion 2 substantially parallel to the bottom wall portion 1 b of the base main body portion 1. It is connected. A connecting portion between the vertical plate portion 11 constituting the one end portion of the inner wall portion W ₂ and the connecting plate portion 2 serves as a deformation base point portion 12 for bending deformation of the inner wall portion W ₂ , and an outer periphery of the deformation base point portion 12. By forming the surface into an arc shape with the center (C ₁₂ ) at a position different from the arc center (C ₁₁ ) of the bent portion of the inner peripheral surface, the deformation base point portion 12 has a thickness (T _The thickness (T ₂ ) is thinner than ₁ ). As a result, the inner wall portion W ₂ is easily bent and deformed around the deformation base point portion 12. Further, the other end portion of the inner wall portion W ₂ is a free end portion 8 a that reaches the base body portion 1 side from the arc center C ₀ .

On the other hand, when the outer wall portion W ₁ is bent and deformed, the portion of the easily deformable groove 9 and the connecting portion between the outer wall main body portion 7 and the inclined plate portion 6 become the deformation base portions 13 and 14, respectively. Further, an opening 15 is formed between the upper ends of the pair of inner wall portions W _{2 so} that the pipe materials P ₁ and P ₂ can be accommodated in the tube material accommodating portion 3. E) is narrower than the outer diameter (D ₁ ) of the tube material P ₁ having the smallest outer diameter that can be accommodated in the tube material accommodating portion 3. Further, each modification base portions 13, 14 of the outer wall section W ₁ are both because it is located opposite the opening 15 than the deformable base portion 12 of the inner wall W _2, deformation outer wall W ₁ bends when, in the deformation starting point portion 12 of the inner wall W ₂ is displaced in the direction of deflection of the outer wall section W _1, the displacement amount of the inner wall portion W ₂ with respect to the absolute space, the inner wall portion W by the bending deformation outer wall W ₁ and displacement of the _second modified base portion 12, is the sum of the deflection of the inner wall portion W ₂ against the outer wall section W _1, the displacement amount with respect to the original position of the inner wall portion W ₂ is increased, the base V ₁ The range of the outer diameter of the tube material that can be accommodated in the tube material accommodating portion 3 is widened.

On the other hand, the lid body L ₁ includes a top plate portion 21 having a flat mountain shape and a pair of side wall portions 22 integrally formed at both lower ends of the top plate portion 21. At the lower end portion of the side surface, a hollow shape fitted into a fitting groove 16 formed between the lower end portion of the outer wall portion W ₁ of the base V ₁ and both end portions in the width direction of the base body portion 1. The fitting protrusion 23 is formed over the entire length.

Next, with reference to FIG. 3, the case where the pipe material P ₁ having the minimum outer diameter (D ₁ ) is accommodated and held on the base V ₁ of the protective cover K ₁ will be described. Figure 3 (b) is therefore against the tubing P ₁ into the opening 15 of the base V ₁ of the protective cover K _1, a cross-sectional view showing a state immediately before pushing, the (b) it is tube P ₁ FIG. 4 is a cross-sectional view showing a state in which is housed in the tube material housing portion 3 of the base V ₁ . The minimum outer diameter to be held (D ₁₎ of the tube P ₁ to the base V ₁ of the protective cover K ₁ of, as shown by a two-dot chain line in FIG. 3 (b), the opening of the base V ₁ When the pipe material P ₁ is applied and pushed into the portion 15, the pipe material P ₁ is disposed between the vertical plate portions 11 of the pair of inner wall portions W ₂ , and the vertical plate portions 11 are pressed outward. The pair of outer wall portions W ₁ and the pair of inner wall portions W ₂ are elastically deformed to the maximum as shown by the two-dot chain line in FIG. In this case, the outer wall portion W ₁ includes a deformation base point portion 14 at one end (lower end) of the outer wall main body portion 7 and another deformation base point portion 13 (easy deformation groove 9) at the center in the width direction of the outer wall main body portion 7. Although elastically deformed outwardly, respectively in the center, an inner wall portion W ₂ include, but are not hardly elastically deformed against the outer wall section W _1, displaced outwardly following the elastic deformation of the outer wall W ₁ (position It only shifts). When the maximum outer diameter portion of the pipe material P ₁ passes between the vertical plate portions 11, the outer wall portion W ₁ that has been greatly elastically deformed outward is elastic as shown by the solid line in FIG. By restoring the original shape by the restoring force, the pipe material P ₁ is accommodated and held between the pair of inner wall portions W ₂ . In this state, a relationship of (D ₁ = 2R ₁ ) is established between the outer diameter (D ₁ ) of the pipe material P ₁ and the radius R ₁ of the inner peripheral surface of the pair of inner wall portions W ₂ . for, the inner wall section W ₂ is without elastic deformation, the pipe material P ₁ is held only by the inner wall section W ₂ Luwan song shape. In other words, the pipe material P ₁ is not subjected to the pressing force due to the bending deformation of the pair of outer wall portions W ₁ and the pair of inner wall portions W ₂ .

Next, a case where the large-diameter pipe P ₂ is accommodated and held on the base V ₁ of the protective cover K ₁ will be described with reference to FIG. Figure 4 (a) shows a state in which the base V ₁ of the tube housing unit 3 of the protective cover K ₁ tube P ₂ of large diameter is held in cross-sectional view showing in comparison with the holding of the small diameter of the tube P ₁ The same (B) is a cross-sectional view of a state in which the lid L ₁ is covered with the base V ₁ in which the large-diameter pipe P ₂ is accommodated and held. In the same manner as in the case of accommodating the small diameter pipe P ₁ , when the large diameter pipe P _{2 is applied} to the opening 15 of the base V ₁ and pushed toward the base main body 1, As in the case of the small-diameter pipe P ₁ , the pair of inner wall portions W ₂ are hardly elastically deformed, and only the pair of outer wall portions W ₁ are centered on the deformation base points 13 and 14, and the pipe P _1. When the largest outer diameter portion of the pipe material P ₂ passes through the opening 15 and is elastically deformed to a greater extent than in the above case, the amount of elastic deformation of the pair of outer wall portions W ₁ that have been greatly elastically deformed outward is small. And are displaced inward from each other. On the other hand, the pair of inner wall portions W ₂ are displaced outward by elastic deformation of the outer wall portion W ₁ , and the pair of inner wall portions W ₂ themselves are elastically deformed outward about the deformation base point portion 12. As described above, the pair of outer wall portions W ₁ is deformed outwardly in the width direction with only the half of the opening 15 side centered on the deformation base point portion 13, and the pair of inner wall portions W ₂ is The pipe P ₂ is deformed outwardly with the deformation base point 12 as the center, and the pipe member P ₂ is pressed from both sides by the elastic restoring forces of the pair of outer wall portions W ₁ and the pair of inner wall portions W ₂ . It is accommodated and held between the pair of inner wall portions W _2. Since the relationship of (D ₂ > 2R ₂ ) is established between the outer diameter (D ₂ ) of the pipe material P ₂ and the radius (R ₂ ) of the inner peripheral surface of each inner wall portion W ₂ , the pipe material P ₂ theory is supported four points by each end of the circumferential direction the pair of inner wall portions W _2.

The pair of inner wall portion W ₂ at four points supported large diameter tube P ₂ of the axis and (C _2), without the pair of inner wall portions W ₂ is deformed, the pair of inner wall portions W ₂ form and tubing of small diameter which are facing circumferential surface which is supported (P ₁₎ of the axis (C ₁₎ by are substantially coinciding, moreover arc center (C ₀₎ of the pair of inner wall portions W ₂ in which the arcuate and Match.

For this reason, the pipes P ₁ and P ₂ having different outer diameters may be accommodated and held in the same protective cover K ₁ , and the axial centers of the _two pipes P ₁ and P ₂ as shown in FIG. Since C ₁ and C ₂ are substantially the same, when connecting the _two pipe materials P ₁ and P ₂ with the different diameter connectors M, the shaft centers of the respective pipe materials P ₁ and P ₂ and the different diameter connectors M are provided. Are almost identical and can be connected smoothly. In FIG. 6, the different diameter connector M connecting the pipe materials P ₁ and P ₂ is housed and protected by an attached protective cover (not shown). In FIG. 6, reference numeral 41 denotes a wall surface on which the pipe materials P ₁ and P ₂ are arranged.

Note that after receiving holding the tubing P ₁ or the P ₂ on the base V ₁ was, in FIG. 4, as shown in (b), base V ₁ housed holding tubing P ₁ or the P ₂ lids The body L ₁ is covered. That is, when the side of the opening 15 of the base V ₁ pushes the lid L _1, the fitting projection 23 of the inner side walls 22 of the lid L ₁ is, base that is deformed outwardly By being elastically deformed and expanded by sliding on the outer wall W ₁ of V ₁ , the original shape is restored, and each fitting projection 23 of the lid L ₁ is fitted to each fitting groove 16 of the base V _1. Fitted.

A protective cover K2 according to the _second embodiment of the present invention is shown in FIG. FIG. 5 is a cross-sectional view of a state in which the large-diameter pipe P ₂ is accommodated on the base V ₁ ′ of the protective cover K ₂ . The protective cover K _{2 of the} second embodiment is different from the protective cover K ₁ only in the base V ₁ ′, and the base V ₁ ′ is formed on the outer wall W ₁ of the base V ₁ and is easily deformed. The structure without the groove 9 is the same as that of the protective cover K1 of the _first embodiment. Although the inner wall portion W ₂ is bent and deformed around the deformation base portion 12 by accommodating the large-diameter tube material P ₂ in the tube material accommodating portion 3 of the base V ₁ ′, the outer wall portion W is substantially the same. ₁ ′ differs in that it bends and deforms around only the deformation base point portion 14 at one end in the circumferential direction of the outer wall main body portion 7.

Next, with reference to FIG. 7, the protective cover K ₂ of Example 3 of the present invention. Figure 7 (b) is a sectional view showing a state where the small diameter of the tube P ₁ is housed in tubing accommodating portion 3 'on the base V ₂ of the protective cover K _2, the (B) is a tube P ₁ the accommodated in the base V ₂ is a cross-sectional view of a state in which covering the lid L _1. The same reference numerals are given to the same parts as the protective cover K _1, and “′” is given to the same parts with the same reference numerals, and only the parts different from the protective cover K ₁ will be described to avoid duplication. Base V ₂ of the protective cover K ₂ are, with respect to the base V ₁ of the protective cover K _1, the inner wall portion W ₂ ', together with the whole of which is formed in an arc shape around the arc center C ₀ The outer wall portion W ₁ ′ is not formed in an arc shape centered on the arc center C ₀ , the distal end portion of the outer wall main body portion 7 ′ of the outer wall portion W ₁ ′, and the distal end of the inner wall portion W ₂ ′. The portion on the base end side (side of the base body portion 1) slightly from the portion is connected by the connecting plate portion 2 ′ having an arc shape, so that the entire inner wall portion W ₂ ′ having an arc shape is formed. The difference is that both end portions are formed in a free end shape.

Therefore, the diameter of the tube P ₁ to receive and retain the base V ₂ is pushed wants against the tubing P ₁ into the opening 15 of the base V ₂ ', by a two-dot chain line in FIG. 7 as shown, tubing P ₁ in the 'other free end portion 8b of the' inner wall portion W ₂ abuts, is deflected a pair of the outer wall W ₁ 'and a pair of inner wall portion W _2' outwardly. When the maximum outer diameter portion of the pipe member P ₁ passes between the free end portions 8b ′ of the pair of inner wall portions W ₂ ′, the pair of outer wall portions W ₁ ′ and the pair of inner wall portions W that have been bent outwardly are deformed. ₂ ′ is restored to the original shape, and the pipe material P ₁ is held by the original shape itself of the pair of inner wall portions W ₂ ′, as indicated by the solid line in FIG. After that, as shown in FIG. 7B, the lid L ₁ is covered with the base V ₂ on which the pipe material P ₁ is held.

Further, when the large-diameter pipe P ₂ is held on the base V ₂ , as shown by a two-dot chain line in FIG. 7, the pair of outer wall portions W ₁ ′ are deformed base points 13 ′ (9 ′), Each of the pipe members P ₂ is bent and deformed with respect to the connecting portion 2 ′ as a result of the bending deformation of the pair of inner wall portions W ₂ ′ around the deformation base point portion 12 ′. Thus, the pair of outer wall portions W ₁ ′ are held by the pair of inner wall portions W ₂ ′ displaced along the outer side by the deflection deformation.

Next, with reference to FIGS. 8 and 9, will be described protective cover K ₃ of Example 4 of the present invention. FIG. 8 is an exploded perspective view of the base V ₃ , the tube material holder S and the lid L ₃ constituting the protective cover K ₃ , and FIG. 9 shows the protective cover K ₃ in a state where the tube material P ₂ is also accommodated. FIG. The bases V ₁ (V ₁ ′), V ₂ of the protective covers K ₁ , K ₂ are the outer wall part W ₁ (W ₁ ′) and the inner wall part W constituting the pipe material housing part 3 in the base body part 1. ₂ (W ₂ ′) is integrally formed, whereas the protective cover K ₃ is different in that the base V ₃ and the tube material holder S are formed separately. At both ends in the width direction of the main body plate portion 31 of the base V ₃ , a pair of inner fitting grooves 32 into which the fitting plate portion 34 of the tube material holding body S is fitted are formed and a lid body is formed. A pair of engaging bodies 33 for engaging the L ₃ engaging protrusions 35 are formed to be inclined outward. The tube material holder S is formed separately from the base V _3, and on the upper surface side of the fitting plate 34, the outer wall W ₁ (W ₁ ) that constitutes the bases V ₁ (V ₁ ′) and V ₂ is formed. _The outer wall portion W ₁ ″ and the inner wall portion W ₂ ″ corresponding to ₁ ′) and the inner wall portion W ₂ (W ₂ ′) are integrally formed.

Then, the main body plate portion 31 of the tube material holder S is rotated by 90 ° with the main body plate portion 31 inserted between the engaging bodies 33 of the base V ₃ , so that the main body plate portion 31 is fitted into the inner fitting groove 32 of the base V _3. The plurality of tube material holders S are attached to the base V ₃ at predetermined intervals along the longitudinal direction thereof. In this state, the outer wall W ₁ ″ and the inner wall W ₂ ″ are flexibly deformed by pushing the pipe P ₂ through the opening 15 ″ of each pipe holder S, and the plurality of pipe holders S holding the tube P _2. then, by pushing the U-shaped section of the cover body L ₃ relative to the base V _3, to restore the original shape after opening of the lid body L ₃ is expanded The engagement protrusion 35 formed on the inner peripheral surface side of the opening of the lid L ₃ engages with the engagement body 33 of the base V ₃ , and the tube material P ₂ is held by the plurality of tube material holders S. The lid L ₃ is covered with the base V ₃ .

Also in the protective cover K ₃ of the fourth embodiment, the tubular material holder S can hold the large-diameter tubular material P ₂ by bending and deforming the outer wall portion W ₁ ″ and the inner wall portion W ₂ ″.

In each of the first to fourth embodiments, the outer wall W ₁ (W ₁ ′) and the inner wall W ₂ (W ₂ ′) of the bases V ₁ (V ₁ ′) and V ₂ or the pipe material holder are used. In order to accommodate and hold two kinds of pipe materials P ₁ and P ₂ having different outer diameters by cooperating with the deformation of the deformation of the outer wall portion W ₁ ″ and the inner wall portion W ₂ ″ of S, the small-diameter pipe material P ₁ is held. In this case, the outer wall W ₁ (W ₁ ′) and the inner wall W ₂ (W ₂ ′) of the bases V ₁ (V ₁ ′) and V ₂ are not bent in their original shapes. Only when holding the small diameter pipe P ₁ by the shape itself and holding the large diameter pipe P ₂ , the outer wall W ₁ (W ₁ ') and the inner wall of the bases V ₁ (V ₁ ') and V ₂ W ₂ (W ₂ ') etc. is bent and deformed. However, even when holding the minimum diameter of the tubing of the retainable plurality of types of tubing, base V ₁ (V ₁ '), the outer wall portion W ₁ of the V ₂ (W _1') and the inner wall section W ₂ ( W ₂ ′) and the like may be flexibly deformed to hold the tube with the smallest diameter, and the number of plural types of pipes that can be held is not limited to two but also three. There may be cases.

  In addition, when protecting two types of pipe materials having different outer diameters with the same protective cover according to the present invention, one of the advantages is that there is almost no misalignment of the pipe materials having different outer diameters. “There is almost no misalignment” means that the axial centers of the pipes having different outer diameters do not have to coincide completely, and the pipes are in contact with the base bottom wall. This means that the misalignment of the pipes having different outer diameters is smaller than when a conventional protective cover that accommodates and protects them is used.
