As shown in (b), the overall connection body 140 has a substantially rectangular shape in a plan view and a substantially flat triangular shape in a side view, and includes a lower bottom portion 141, an inclined portion 142, an upper bottom portion 143, and a side wall 144. The length of the lower bottom portion 141 from the front end portion 140a to the rear end portion 140b of the coupling body 140 is L1 + 2L2. Further, the inclined portion 102 and the first inclination are mainly inclined so as to rise upward from the front end portion 140a to the rear end portion 140b. The inclined portion 142 is formed by the portion 112 ″, and the side wall 134 (height 2H) of the base 130 and the first side wall 114 ″ (height H) of the first divided body 110 ″ are formed at the rear end portion 140b. Side wall 144 of height 3H is formed.

  In addition, the inclined portion 142 is formed with the concave stripes 146 on the same straight line. And as shown in FIG.6 (c), in order to integrate each division body and to fix to a mounting surface, the fixing hole of each member continues in the height direction, and the fixing hole 148 is formed.

  A method for assembling the spacer connector 140 will be described below. First, the second engagement recess 125b (see FIG. 4) of the spacer 100 and the engagement protrusion 125a ′ (see FIG. 5) protruding from the front end portion 130a of the base 130 are engaged, and the spacer 100 and the base 130 are engaged. And Next, the lower bottom portion 111 ″ of the first divided body 110 ″ is brought into contact with the upper surface 132 of the base 130, and the first ridge 116 b ″ is fitted on the recess 136 (second recess 126 a ′). When the first divided body 110 ″ is slid along the recess 136, the locking claws 117a ″ and the first locking grooves 117b ′ are engaged, and the first divided body 110 is engaged. ″ Is locked by the base 130, and the first divided body 110 ″ is disposed on the base 130 so that the rear end portion 110 b ″ of the first divided body 110 ″ is positioned on the rear end portion 130 b of the base 130. The spacer coupling body 140 is formed.

  By combining the plurality of bases 130 in the longitudinal direction or the height direction by the same assembling method as described above, the first divided body 110 and the second divided body 120 are further stacked thereon to have a desired height. Spacers can be formed. As shown in FIG. 7, for example, four first divided bodies 110 and four second divided bodies 120 may be combined to form a spacer having a height of 4H, and a spacer having a height of 5H may be formed. The seven first divided bodies 110 and the six second divided bodies 120 may be combined. Therefore, although the spacer of the present invention consists of two types, it can be composed of a plurality of first divided bodies 110 and a plurality of second divided bodies 120.

  In addition, the spacer 100 of this embodiment is an injection-molded product using a synthetic resin such as an ABS resin, and each of the above parts is integrally molded at the time of injection molding. However, materials and manufacturing methods are not limited to this.

  FIG. 8 shows a protective cover 200 as a protective member for wiring / piping material accommodation used in the present embodiment. As shown in FIGS. 8 (a) and 8 (b), the protective cover 200 is formed of a synthetic resin in a long straight shape whose cross-sectional shape is continuous in the longitudinal direction, and the cross-sectional view is substantially rectangular. And this protective cover 200 can accommodate a long wiring or piping inside.

  The protective cover 200 includes a base 201 for fixing to the mounting surface and a lid 202 that engages with the base 201. The base 201 has a generally square shape in cross section, and side portions 201b are erected from both ends of the bottom surface 201a. An engaged portion 201c is formed at the tip of the side portion 201b. On the other hand, the lid body 202 is curved in a substantially square shape in cross section, and engaging portions 202a are formed at both ends thereof. By engaging the engaging portion 202a with the engaged portion 201c, the opening of the base 201 is covered with the lid 202. The lid 202 is bent in the width direction and then placed on the base 201, and the engaged portion 201c is sandwiched by the engaging portion 202a by the elastic force of the lid 202 returning to the original, and the lid 202 Can be attached to the base 201. In this protective cover 200, both the base 201 and the lid body 202 are flexible in the longitudinal direction, and the engagement between the engaging portion 202a and the engaged portion 201c can be achieved even when the base 201 is bent. However, it is more preferable that the amount of bending of the base 201 is within the bending range of the lid 202.

  In addition, the shape and material of the protective material for wiring / piping material accommodation are not limited to the protective cover 200 of FIG. For example, an integrated synthetic resin protective tube 200 </ b> A having a circular cross-section continuous in the longitudinal direction may be used like a hard vinyl electric conduit shown in FIG. 9. The protective material may be made of a metal such as aluminum. Therefore, the user can arbitrarily select the shape and material of the protective material according to the intended use.

  As shown in FIG. 10, the protective cover 200 can be deformed in the z direction and bent by a predetermined amount. In a schematic side view, the angle between the tangent (tangent plane) of the bending curve of the protective cover 200 and the horizontal plane when the other end is deformed in the z direction with one end fixed to the horizontal plane is defined as a deflection angle θ. When the bending angle θ is in a predetermined range (elastic deformation region), the protective cover 200 elastically deformed in the z direction tries to return from the bent state to the original linear state. However, when the deflection angle θ becomes larger and exceeds the elastic limit (yield point), the protective cover 200 is plastically deformed and broken. In the present invention, the “bending range” of the protective cover means that the bending angle θ is within the elastic deformation region.

  For example, in the synthetic resin protective cover 200 of FIG. 8, the elastic deformation region is when the deflection angle θ is about 2 to 3 ° or less, and when the deflection angle θ exceeds about 2 to 3 °, the protective cover 200. Breaks due to plastic deformation. On the other hand, in the protective tube 200A having a circular shape in section in FIG. 9, the elastic deformation region is when the deflection angle θ is about 4 to 5 ° or less, and plastic deformation occurs when the deflection angle θ exceeds about 4 to 5 °. Break. That is, the range of the elastic deformation region varies greatly depending on the shape and material. Therefore, the “bending range” is not limited to the bending range (bending angle θ) in the protective cover 200 of the present embodiment. Note that the range of the elastic deformation region varies greatly depending on the external environment such as the temperature, and the above values assume an environment at room temperature. That is, the protective material of the present invention includes those that are not broken or broken.

  FIG. 11 shows a protective material installation structure 10 in which a protective cover 200 as a protective material for wiring / piping material accommodation is installed on the mounting surface T in a state where the protective cover 200 gets over the stepped portion S having a height of 2H via the spacer 100. Show. In this protective material installation structure 10, for convenience of explanation, the mounting surface T is illustrated as being on a horizontal wall surface, and based on this, the vertical and horizontal directions are defined and each member will be described in detail. It may be on an upright wall surface or a ceiling surface, and is not limited to this embodiment.

  As shown in FIG. 11, in the protective material installation structure 10, the mounting surface T includes a first mounting surface T1 and a second mounting surface T2 that is convex with respect to the first mounting surface T1, and the first mounting surface T1. And the second mounting surface T2 form a stepped portion S having a height of 2H. Note that the second mounting surface T2 is not limited to a planar wall surface, and includes obstacles such as a draining structure, rain gutter, and wiring installed on the wall surface.

  FIG. 11C is a schematic side view of the protective material installation structure 10. The protective material installation structure 10 has a spacer so as to form an inclined portion 102 that is inclined upward in the bending range of the protective cover 200 toward the stepped portion S (from the first mounting surface T1 to the second mounting surface T2). 100 is disposed on the first mounting surface T1 adjacent to the stepped portion S, and the protective cover 200 is brought into contact with the inclined portion 102, so that the protective cover 200 is bent within the bending range and the stepped portion S is overcome. It is attached to 1 attachment surface T1.

  As shown in FIG. 11C, since the tangent plane of the deformed protective cover 200 is substantially the inclined portion 102, the bending angle θ of the protective cover 200 and the inclined angle α of the inclined portion 102 are substantially the same. That's it. In the present embodiment, the inclination angle α is set to 1.5 °, and the inclination angle α is in the elastic deformation region (0 <α <2 to 3 °) of the protective cover 200. If the deflection angle θ exceeds the elastic deformation region, the protective cover 200 may be plastically deformed and broken, so the inclination angle α is preferably within the elastic deformation region. The inclination angle α is not limited to 1.5 °, and can be arbitrarily changed depending on the shape and material of the protective material. For example, when laying the protective tube 200A having a circular section in FIG. 9 having a larger elastic deformation region than the protective cover 200, the inclination angle α can be increased to 4 to 5 °. That is, if the bending angle θ is within the bending range (elastic deformation region) of the wiring / piping material housing protective material, the inclination angle α can be arbitrarily set according to the height of the stepped portion S.

  Further, since the upper bottom portion 103 is gently bent so as to form a substantially arc with respect to the inclined portion 102, the protective cover 200 is gently formed so as to form a substantially arc along the inclined portion 102 and the upper bottom portion 103. It is bent.

  Hereinafter, a method of installing the spacer 100 and the protective cover 200 on the mounting surface T will be described. First, the first mounting surface T1 is positioned at a position adjacent to the stepped portion S so that the spacer 100 forms a slope having an inclination angle α in which the inclined portion 102 increases from the first mounting surface T1 toward the second mounting surface T2. It arrange | positions so that the lower bottom part 101 may contact | abut. At this time, the spacer 100 is fixed to the first mounting surface T1 through the fixing holes 118 and 128.

  Next, the protective cover 200 is disposed on the mounting surface T from above so that the spacer 100 is sandwiched between the protective cover 200 and the mounting surface T. As shown in FIG. 11 (c), the first attachment surface T1 in a state where the protective cover 200 is brought into contact with the inclined portion 102 of the spacer 100, the protective cover 200 is bent along the longitudinal direction, and the stepped portion S is overcome. And the protective cover 200 can be installed on the attachment surface T via the spacer 100 by fixing to the second attachment surface T2. The fixing position of the protective cover 200 is not limited to this, and the protective cover 200 may be fixed to either the first mounting surface T1 or the second mounting surface T2, or the protective cover 200 may be fixed on the spacer 100. The fixing holes 118 and 128 may be used for fixing. Further, the step wall Sw of the stepped portion S rising from the first mounting surface T1 is also a part of the mounting surface T, and the spacer 100 may be fixed to the step wall Sw.

  Hereinafter, the effect of the spacer 100 and the protective material installation structure 10 of one embodiment of the present invention will be described. Needless to say, the operation and effect of the spacer 100 described below also applies to the case where the first divided body 110 is used alone and the case where a connected body composed of a plurality of divided bodies is used.

  By disposing the stepped portion climbing spacer 100 on the first mounting surface T1 and installing the protective cover 200 on the mounting surface T via the spacer 100, the protective cover 200 comes into contact with the inclined portion 102 of the spacer 100. And elastically deformed. Since the inclined portion 102 is inclined upward at an angle α toward the stepped portion S, the protective cover 200 is bent along the inclined portion 102 so that the protective cover 200 is mounted on the mounting surface over the stepped portion S. It can be installed at T. That is, it is not necessary to divide and arrange the protective cover 200 before and after the stepped portion S, and it is only necessary to attach the spacer 100 to the attachment surface T and install the protective cover 200 thereon. The protective cover 200 can be easily installed on the mounting surface T having the stepped portion S with a simpler overall structure (protective material installation structure 10). That is, it is possible to reduce the processing cost of the protective cover 200 and improve the mounting workability.

  Further, in the prior art, the strength may be reduced at the joint portion between the joint or the bellows structure for dividing and reconnecting the straight protective cover and the straight portion of the protective cover. Since the body-shaped protective cover 200 can be directly installed on the mounting surface T, the risk of a decrease in strength of the protective cover 200 and the protective material installation structure 10 is reduced.

  Furthermore, the spacer 100 is located between the protective cover 200 and the mounting surface T, and the protective cover 200 covers the spacer 100 from above (see FIG. 11B). That is, while the bellows structure and the joint structure in the prior art are exposed to the outside, the proportion of the spacer 100 exposed to the outside is small, and the appearance of the protective material installation structure 10 in the part where the stepped portion S gets over is improved. be able to. Therefore, by using the spacer of the present invention, workability in laying the protective material and aesthetics in the protective material installation structure are improved.

  In the spacer 100, the first divided body 110 and the second divided body 120 are divided so as to be connectable in the longitudinal direction at a position where the height is substantially halved, so that the first divided body 110 and the second divided body are separated. 120 can be connected in the longitudinal direction to change the height from H to 2H, and the height of the entire spacer can be brought close to the height of the stepped portion S. Further, since the first divided body 110 and the second divided body 120 can be stacked, the height of the entire spacer can be further adjusted. For example, the first divided body 110 is disposed on a substantially rectangular parallelepiped base 130 formed by stacking the first divided body 110 on the second divided body 120, and the substantially continuous inclined portion 142 is formed. In addition, by disposing the spacer 100 on the front end portion 130a side of the base 130, a connecting body 140 having a height of 3H can be formed (see FIG. 6). Therefore, as shown in FIG. 7, the height of the spacer is adjusted according to the height of the stepped portion S by stacking the plurality of first divided bodies 110 and second divided bodies 120 while being connected in the longitudinal direction. can do.

  In the spacer 100, the upper bottom portion 103 is continuously formed from the inclined portion 102 to the rear end portion 100b side and is formed in parallel to the lower bottom portion 101, so that when the protective cover 200 is installed, While the installation position of the protective cover 200 is guided by the upper bottom portion 103, the protective cover 200 can be gently bent along the inclined portion 102 and the upper bottom portion 103 that are gently continuous with each other (see FIG. 11C). ). In addition, since the upper bottom portion 103 is gently bent with respect to the inclined portion 102 and does not form an acute portion (acute angle), the protective cover 200 is not attached to the corner of the spacer 100 when the protective cover 200 is installed on the spacer 100. It is possible to reduce the frequency of contact and damage to the part. Note that the protective material can be bent more gently when the upper bottom portion 103 is bent in a substantially arc shape with respect to the inclined portion 102 as in the present embodiment, but the upper bottom portion 103 is changed to the inclined portion 102. On the other hand, even if it is not bent in a substantially arc shape, the bending angle between the inclined portion 102 and the upper bottom portion 103 is an obtuse angle and is bent gently, and thus the same effect as described above is obtained.

  In the spacer 100, the first engagement recess 115 and the second engagement recess 125b are respectively provided in the rear end portions 110b and 120b of the first divided body 110 and the second divided body 120, and the engagement protrusion 125a is the second. The front end portion 120a of the divided body 120 is protruded. That is, when the first divided body 110 is used as a spacer or when the connecting body 140 is used as a spacer, the spacer rear end is brought into contact with the step wall Sw of the stepped portion S, and the spacer is set to the step S. The spacers can be arranged adjacent to each other, and the spacer can be fixed to the step wall Sw. That is, the freedom degree of the spacer installation position and the workability in spacer arrangement are improved.

  In the spacer 100, the first divided body 110 and the second divided body 120 include concave stripes 116a and 126a and convex stripes 116b and 126b. Since the concave stripes 116a and 126a and the convex stripes 116b and 126b can be fitted and slidable with each other, when the divided bodies are stacked and moved to a predetermined position, the movement of the divided bodies is guided along the longitudinal direction. Is done. When the divided body is moved along the longitudinal direction, the locking claws 117a engage with the locking grooves 117b and 127, and the divided body is locked at a predetermined position. Therefore, positioning in the vertical relationship of each divided body can be easily performed, and the base 130 and the coupling body 140 can be assembled quickly and easily.

  In the spacer 100, each of the divided bodies 110 and 120 includes mounting portions 116aa and 126aa, and the upper bottom portions 113 and 123 are gently bent with respect to the inclined portions 112 and 122. 116aa and 126aa are linearly inclined upward from the front end portions 110a and 120a to the rear end portions 110b and 120b in a side view. That is, when the divided bodies 110 and 120 are stacked one above the other, the ridges 116b and 126b and the side wall bottom ends 114a and 124a constituting the lower bottom portions 111 and 121 of the upper divided bodies 110 and 120 are divided into the lower parts. Since the front end portions 110a and 120a are in contact with the placement portions 116aa and 126aa of the bodies 110 and 120 from the rear end portions 110b and 120b, the divided bodies 110 and 120 are held in a stable state without rattling. Can be stacked.

  In the protective material installation structure 10, the protective cover 200 includes a base 201 fixed to the mounting surface T and a lid 202 that engages with the base 201, and the base 201 and the lid 202 are in a bent state. When the protective cover 200 with the lid 202 attached to the base 201 is installed on the mounting surface T, the lid 202 is detached even if the protective cover 200 is bent. There are few defects. In addition, since the lid 202 can be freely attached and detached after the protective cover 200 is installed on the attachment surface T, the wiring and piping can be attached and detached, and the maintenance of the wiring and piping and the degree of freedom of work are possible. Will improve.

  In addition, the protective material installation structure of this invention is not restricted to embodiment mentioned above. For example, as shown in FIG. 12A, when the first mounting surface T1 is on both sides of the second mounting surface T2 and two stepped portions S1 and S2 are formed, the stepped portions S1 and S2 are adjacent to each other. By disposing the two spacers 100 at the positions where the protective cover 200 is placed, the protective cover 200 can be installed on the mounting surface T in a state of overcoming the stepped portion S1 and the stepped portion S2. The protective material installation structure 10 is not limited to the arrangement of the spacer 100. For example, when the height of the stepped portion S is H or less and the stepped portion S can be overcome only by the first divided body 110. The first divided body 110 may be arranged as a spacer. At this time, a convex engagement convex portion 125a that is a connecting means with the second divided body 120 is formed in the second divided body 120, and a concave engagement concave portion 115 is formed in the first divided body 110. Therefore, the rear end portion 110b of the first divided body 115 can be brought into contact with the step wall Sw. On the other hand, as shown in FIG. 12B, when the height of the stepped portion S is 4H, a connecting body 150 that is a combination of a plurality of types of the first divided body 110 and the second divided body 120 is arranged as a spacer. do it. That is, according to the height of the stepped portion S, for example, as shown in FIG. 7, a plurality of first divided bodies 110 and a plurality of second divided bodies 120 are formed to form a spacer connection body, and a protective material installation structure is formed. Can be configured.

  Further, the second mounting surface T2 may be a non-planar obstacle, for example, a draining structure X installed on a wall surface of a building as shown in FIG. At this time, the stepped portion S is formed by the draining structure X and the first mounting surface T1. The draining structure X should not be in contact with the protective cover 200 due to its function, and needs to be installed on the mounting surface T in a state where the protective cover 200 is floated from the draining structure X. As shown in FIG. 13, by installing two spacers 100 on both sides of the water draining structure X and causing the protective cover 200 to contact and bend against the inclined portion 102, the protective cover 200 does not contact the water draining structure X. It is installed on the mounting surface T so as to float and straddle. At this time, the restoring force of the elastically deforming protective cover 200 is supported by the spacer 100, and even if an external force is applied to the protective cover 200 on the side of the draining structure X, the upper bottom surface 103 of each spacer 100 is the height of the draining structure X. Now, since the protective cover 200 is supported, it is possible to prevent the protective cover 200 and the draining structure X from coming into contact with each other and the draining structure X from being damaged.

  Further, the stepped portion crossing spacer of the present invention is not limited to the configuration of the above-described embodiment. For example, the length L1 of the first divided body 110 may be formed to be equal to the length L2 of the second divided body 120, or L1 may be formed to be larger than L2. Further, the connecting means between the first divided body 110 and the second divided body 120 may be a means other than the engaging convex part and the engaging concave part, and a hook-and-loop fastener, a double-sided tape, a magnet or the like is employed as the connecting means. Is also possible. Or the structure which only contact | abuts the rear-end part 110b of the 1st division body 110 and the front-end part 120a of the 2nd division body 120, without forming a connection means. Further, the first upper bottom portion 113 and the second upper bottom portion 123 may be bent so as to have corners without being bent in a substantially arc shape with respect to the first inclined portion 112 and the second inclined portion 122. .

(Modification 1)
The stepped portion climbing spacer of the present invention may be an integrated structure that does not have a divided structure, or may be composed of three or more types of divided bodies. Further, the stepped portion climbing spacer only needs to have an inclined portion that rises and inclines from the first mounting surface to the second mounting surface. For example, as in the spacer 100A in FIG. It is good also as a simple structure which is not provided with a joint recessed part, an engagement convex part, a concave line, a convex line, a latching claw, a latching groove, a mounting part. And like the above-mentioned embodiment, an inclination part does not need to be planar. For example, in the spacer 100B illustrated in FIG. 14B, the inclined portion has a curved shape. In the spacer 100C shown in FIG. 14C, the whole is formed in a substantially arc shape in a side view. And like the spacer 100D shown in FIG.14 (d), an inclination part may not be a continuous plane, and an inclination part may incline in step shape. Further, the shape of the spacer is not limited to this embodiment, and the protective cover 200 can be bent and can be installed on the mounting surface T in a state of overcoming the stepped portion S like the spacer 100E shown in FIG. If the inclined portion can be formed, the overall shape of the spacer may be flat.

(Modification 2)
FIG. 15A shows a protective tube 200A having a circular cross-sectional view and a spacer 100F for installing the protective tube 200A. The protective tube 200A has a curved inclined surface 102F that is curved in a sectional view (see FIG. 15B) so that the protective tube 200A does not move in the width direction on the spacer 100F while being inclined from the front end portion 100Fa to the rear end portion 100Fb. Further, as shown in FIG. 15B, the spacer 100F can be slidably stacked in the longitudinal direction as in the above-described embodiment.

  Note that the present invention is not limited to the above-described embodiments and modifications, and can be implemented in various modes as long as they belong to the technical scope of the present invention.
