Description

  The present invention relates to a duct device that includes a total of three types of ducts, a long duct, a general accessory duct, and a connection accessory duct, and accommodates and protects wiring and piping materials inside a building wall surface. is there.

First, “basic terms” used in the present specification are defined below.
"Long duct" refers to a long duct that has the same cross-sectional shape over its entire length and is the main component for the storage and protection of wiring and piping materials. Long ducts are connected to each other at straight portions, bent portions, protruding corner portions, entering corner portions, branching portions, etc., or at one end of one long duct at a wall penetrating portion (drawing bent portion) It refers to a short duct that is used to connect only the sections or, further, at the duct end of the long duct, to close the end.
“Accessory ducts” include “general accessory ducts” and “connected accessory ducts”, and “general accessory ducts” have been widely used before the filing of this application, and are fitted on the ends of long ducts. The “connected accessory duct” is an accessory duct according to the present invention that is internally fitted to both the long duct and the general accessory duct. Refers to the attached duct that can be connected by.
An “adapter” is a type of duct in the broad sense, similar to an “attached duct”, but in the industry, this term is conventionally used, which is different from the “attached duct”. In order to change the width or height of the piping material, it refers to an extremely short wiring / piping material that is used between the long duct and the accessory duct or between the long ducts and used auxiliary. And what can be connected to both the long duct and the general accessory duct by internal fitting is referred to as a “connection adapter”, and the “connection adapter” is referred to as a “connection accessory duct” in terms of duct connection. Since the same function is achieved, from the viewpoint of interpretation of the technical scope of the present invention, it should be interpreted as being included in the “connected accessory duct”. That is, “connection adapter” is included in “connection accessory duct” in “claim 1” of “claims”.
In addition, as for “connection of ducts”, in principle, the weight of the connection / attachment duct according to the present invention and the long duct or general attachment duct along the wiring / pipe direction of the wiring / pipe material is regulated. “Duct connection” means that a general accessory duct is externally fitted to the end of a long duct and the weight is not regulated in principle.
As a result, the `` connecting part '' refers to the part of the opening of the connecting accessory duct that is provided in a stepped manner along the wiring and piping direction with respect to the main body part, and the `` connecting port '' It refers to a portion of an opening provided in a general accessory duct for connection with a long duct or other accessory duct.

  A conventional duct apparatus that accommodates wiring / piping materials is composed of a long duct and a plurality of types of accessory ducts. Generally, the connection port portion of the accessory duct is externally fitted to the end of the long duct. The long duct and the attached duct are connected (Patent Document 1).

  In addition, depending on the pipe line, the present invention is not limited to a regular case where two long ducts are connected to each other by a short tubular accessory duct or a bent L-shaped accessory duct on the same wall surface. For example, there is a case where the wiring / piping material drawn out from the back of the wall to the wall surface at the wall penetrating portion is bent as it is to be wired / piped. In this case, it is necessary to directly connect the two types of accessory ducts for the lead-out bent portion and the (planar) bent portion. When it is configured to be connectable, in a regular pipeline, a gap is generated due to poor connection between the long duct and the accessory duct, and the appearance deteriorates.

  In other words, the assembly of wiring / piping materials is basically two long ducts connected via an accessory duct. If connection or connection between the accessory ducts is possible, the long duct and the accessory duct Even if the connection or the connection is hindered, or even if the connection or the connection can be made, there is a problem that the appearance of the connection part or the connection part is poor.

After fixing to ˜W ₃ , the piping material is disposed on the base, and then the lid is covered with the base of each duct. In an embodiment, sequentially from the portion that is bent is drawn piping on the wall table from the wall back (the portion generally included with duct GD ₁ is located), it is assumed for covering the lid with respect to the base. Then, from the wall behind the general accessory duct GD ₁ is arranged from the portion piping wall table is bent withdrawn, to the part where the branch pipe portion generally included with the duct GD ₂ for is arranged, a pair of right and left pipe There are pipes in a two-stage, in the portion of the general accessory duct GD ₂ for the branch pipe portion, upper and lower pipe became a pair a pair each after being branched respectively, are single-stage pipeline. The hot / cold mixing tap M is installed on the wall surface W ₁ when the base is fixed.

The general bent duct GD ₁ for drawing and bending is conventionally used. As shown in FIGS. 3 and 4, the base V ₃₁ fixed to the wall surface W ₁ and the base V _And a lid L ₃₁ that is covered with a pipe _{31. A} pipe member is inserted into the base V ₃₁ in a fixed state so as to match a wall through hole (not shown) that penetrates the wall surface W _1. insertion hole 1 is provided in the lid L _31, 1 single connection port J ₃₁ corresponding to the outer diameter of the cross-sectional shape of the elongated duct LD ₁ is provided. The long duct LD ₁ is connected to the connection port J ₃₁ of the general accessory duct GD ₁ or the connection accessory duct GD ₁ is connected. Further, as shown in FIG. 8, the long duct LD ₁ has a width in which two pipes, each having a pair of a hot water supply pipe P ₁₁ and a water supply pipe P _{12 that} are connected in parallel, are arranged in two upper and lower stages. And has a height. In FIG. 8, P ₂₁ and P ₂₂ indicate a hot water supply pipe and a water supply pipe respectively piped in the upper stage.

The connecting accessory duct CD ₁ for the bent portion is according to the present invention, has an L shape in plan view, and is an accessory duct for enabling piping by bending the piping material by 90 ° on the same wall surface. a is a base V ₁₁ that is fixed to the wall, made of the lid L ₁₁ Metropolitan is covering on the base V _11, it it connected to an opening at both ends along the pipe direction of the lid L ₁₁ part C ₁ is extended along the pipe direction. That is, the connection portion C ₁ is provided with a first connecting portion C ₁₁ having an outer surface shape corresponding to the inner shape of the cross section of the long duct LD ₁ of the lid L _21, generally comes corresponding to the long duct LD ₁ inner shape of the cross section of the opening end portion is a portion of the connecting port of the duct, namely, composed of the second connecting part C ₁₂ and having an outer surface shape corresponding to the outer contour of the cross section of the long duct LD _1. Therefore, each of the first and second connecting portions C ₁₁ and C ₁₂ is formed in a step shape, and the first contact end surface F ₁₁ (the end surface of the long duct LD ₁ is in contact with the step portion. 4 and FIG. 6), and the step portion between the main body portion 2 of the lid body L ₁₁ and the second connecting portion C ₁₂ is a connection port of a general accessory duct corresponding to the long duct LD _1. This is a second contact end face F ₁₂ (see FIGS. 4 and 6) on which the end face of this portion abuts. Among the connecting portions C ₁ , the second connecting portion C ₁₂ is exposed in the circumferential direction of the lid L ₁₁ of the connecting accessory duct CD ₁ in order to expose the whole when the second connecting portion C ₁₂ is connected to the long duct LD ₁ . are formed over the entire, first coupling part C _11, regardless the type of opponent duct connecting, always the whole is covered, the lid L ₁₁ relative to the second connecting portion C ₁₂ The portion facing the opening is partially omitted.

Since the outer surface of the lid body L ₃₁ of the attached duct GD ₁ and the lid body L ₁₁ of the connected attached duct CD ₁ are the same surface, the appearance is good. Thereafter, when the lid L ₂₁ is covered with the base V ₂₁ (see FIG. 8) of the long duct LD ₁ fixed to the wall surface W ₁ , the end of the lid L ₂₁ is attached to the connection. is fitted to the first coupling part C ₁₁ the other in the lid L ₁₁ of the duct CD _1, relatively, inside the end of the first connecting portion C ₁₁ is elongated duct LD ₁ of the lid L ₂₁ is fitted (see FIGS. 1 and 4), connecting the accessory duct CD ₁ and the elongated duct LD ₁ is connected, in this connected state, the connecting accessory second connector C ₁₂ and the elongated duct LD duct CD _{1 The first} lid L ₂₁ is flush with the same plane.

On the other hand, as shown in FIG. 2, in the second piping line R ₂ , compared with the first piping line R ₁ , hot and cold water mixing is performed from the drawn-out bent portion (portion where the general accessory duct GD ₁ is disposed). Since the distance in the vertical direction to the plug M is large, the long duct LD ₁ is disposed between the general accessory duct GD ₁ for the drawer bend and the connection accessory duct CD _1. This is different from the route R ₁ and only this different part will be described. As shown in FIGS. 6 and 7, the upper end of the long duct LD ₁ is connected by being fitted into the connection port J ₃₁ of the general accessory duct GD _{1 in} the same manner as in the prior art. connected accessory is fitted to the first coupling part C ₁₁ of the duct CD _1, relatively, the first connecting portion C ₁₁ is connected is fitted into the end of the long duct LD _1, the connected state in, connected to the outer peripheral surface of the accessory second connecting part C ₁₂ and the elongated duct LD ₁ of the lid L ₂₁ of the duct CD _1, because that is the same plane, it is looking. In addition, since the end face on the lower end side of the vertically arranged long duct LD ₁ is in contact with the first contact end face F ₁₁ of the connection accessory duct CD ₁ , there is no problem that the arrangement position is shifted downward due to its own weight. .

Here, in the first piping line R ₁ , as shown in FIG. 4, the end face of the connection port J ₃₁ of the lid L ₃₁ of the general accessory duct GD ₁ is the second end of the lid L ₁₁ of the connection accessory duct CD ₁ . 2 By abutting against the abutting end face F ₁₂ , the weight margin (connection margin) K _{12 of the} lids L ₃₁ , L ₁₁ of the ducts GD ₁ , CD ₁ is restricted, and similarly, the second piping path R ₂ Then, as shown in FIG. 7, the end surface of one end portion of the lid body L ₂₁ of the long duct LD ₁ abuts on the first contact end surface F ₁₁ of the lid body L ₁₁ of the connected accessory duct CD _1. , weight Charge (consolidated allowance) K ₁₁ of the lid L _21, L ₁₁ of the duct LD _1, CD ₁ is restricted. As described above, the “duct” defined in the item “definition of basic terms” in the paragraph “0002” indicates that each duct is continuous in a state where the weight allowance along the piping direction of each duct is regulated. It is called "concatenation of". On the other hand, in the second piping line R ₂ , weights (connection charges) of the lid bodies L ₃₁ and L ₂₁ that are the insertion lengths of the lid bodies L ₂₁ of the long duct LD _{1 with} respect to the connection port J ₃₁ of the general accessory duct GD ₁ ) K ₃ is not regulated in the normal assembled state. In this way, making each duct continuous along the piping direction corresponds to “duct connection”. In addition, in the above, the reason for limiting to “in the normal assembly mode” is to restrict the insertion length of the long duct from the connection port of the general accessory duct from being excessive in many general accessory ducts. In addition, a “contact piece (stopper)” is provided on the inner surface of the lid, and a long duct is inserted through the connection port of the general accessory duct until it comes into contact with such a “contact piece”. The purpose is to eliminate the “assembling mode”.

The step end surface with the portion 11 is a second abutting end surface F ₂₂ with which the end surface of the connection port J ₃₄ of the general accessory duct GD _{4 for} the entrance corner abuts. Further, the general accessory duct GD ₄ for the corner is the same as that conventionally used, and is installed in the corner N ₂ formed by the respective wall surfaces W ₂ and W ₃ , in the piping direction. Connection ports J ₃₄ are provided at both ends along the line. In FIG. 15, K ₂₁ and K ₂₂ indicate weights (connection charges) of the connection accessory duct CD ₃ , the long duct LD _2, and the general accessory duct GD ₄ , respectively.

For this reason, in any of the first and second piping paths R ₁ and R ₂ , the connecting accessory duct CD ₃ is installed at the protruding corner N ₁ , and along the first piping direction Q ₁ on the wall surface W ₁ . It is finished to work for covering the lid L ₂₂ relative to the base V ₂₂ of fixed elongated duct LD _2. Then, as shown in FIGS. 15 and 16, the lid is covered with the base of the long duct LD ₂ fixed to the wall surface W ₁ , and in this state, the base is fixed to the corner N _2. When the lid L ₃₄ is covered with the base V ₃₄ of the general accessory duct GD ₄ for the corner, the end of the lid L ₃₄ is connected to the connecting accessory duct CD ₃ for the corner. The second connecting portion C ₂₂ is externally fitted, and the second connecting portion C ₂₂ is relatively fitted into the end of the lid L ₁₃ that forms the connection port J ₃₄ of the connecting accessory duct CD ₃ . The outer peripheral surfaces of the lids L ₁₃ and L ₃₄ of the accessory ducts CD ₃ and GD ₄ for the protruding corner portion and the entering corner portion are stepless continuous surfaces.

On the other hand, the second pipe line R ₂ is different in that a long duct LD ₂ is disposed between the connected accessory duct CD ₃ and the general accessory duct GD _{4 in} the installed state of the duct. Therefore, to covering the lid L ₂₂ relative to the base V ₂₂ of the long duct LD ₂ that is previously fixed to the wall W _2. As a result, the first connecting portion C ₂₁ provided in the lid body L ₁₃ of the connecting accessory duct CD ₃ for the projecting corner portion is fitted into the end of the long duct LD ₂ , and the lid body L ₁₃ The outer peripheral surfaces of the second connecting portion C ₂₂ and the lid L ₂₂ of the long duct LD ₂ are stepless continuous surfaces. Lastly, the base V of the general accessory duct GD ₄ for the entrance corner is formed so as to cover the respective end portions of the respective wall surfaces W ₂ and W ₃ facing each other in the orthogonal state of the respective long ducts LD _{2. The} lid body L ₃₄ is covered with ₃₄ .

  In the above embodiment, in each of the connecting portions of the connecting accessory duct and the long duct or the general accessory duct, each end surface of the long duct or the general accessory duct is connected to each of the first or second connection of the connecting accessory duct. Although the case where the weight margin of the connecting portion is the maximum by contacting the first abutting end surface between the portions or the second abutting end surface between the second connecting portion and the main body portion is given as an example. In the invention, “the weight of the connecting portion” includes a state in which the connecting portion is connected while leaving a part of the connecting portion.

  In the said Example, while the 2nd connection part which comprises a connection part is formed over the perimeter of the cover body which comprises a connection attachment duct, a 1st connection part is the said with respect to a 1st connection part. Only the part facing the opening of the lid is partially missing, and when the long duct is coupled to the connection accessory duct, the second coupling part is exposed as it is, It is necessary to form over the entire circumference. However, since the entire first connection portion is always covered by the long duct or the general accessory duct, the first connection portion is partially formed only in a part in the circumferential direction of the lid within the range where the connection function is lowered. It is also possible to do.

  The above embodiment is an example in which the present invention is implemented for the accessory ducts for the bent portion, the projecting corner portion, and the inclined pipe portion, and the connecting duct is provided with the connecting portion. Corresponding to the various shapes of the above, each additional duct for the other straight connecting part, for the lead-out bent part, for the branch pipe part, and for the corner part is also provided with a connecting part and used as a connecting accessory duct. It is also possible.

In the above embodiment, the connecting accessory duct CD ₂ for the inclined pipe portion is provided with a connecting portion only at one of the two connection ports, and the other is because the frequency with which the long duct is connected is overwhelmingly high. It remains a connection port. In this way, considering the connection frequency of the piping material, the connection port that is frequently connected to the specific piping material is left as it is, and either the long duct or the general accessory duct is selected and connected. In such a case, a connecting portion may be provided only in this portion. For example, connecting accessories duct CD ₄ for inner corner portion shown in FIG. 17, only one of the two connection ports connecting portion C ₂ is provided on the other connecting port J ₃₅ are left intact.

  In the above embodiment, the present invention is applied to a duct composed of a base and a lid, but the wiring / pipe material fixed by a fixture called a saddle fixed to the wall surface is used. On the other hand, the present invention can also be applied to a duct having a base that does not have a base, in which the duct itself consisting only of a lid is fixed to the wall surface so as to cover the whole.
