Description

  The present invention relates to a joint pipe cover, and more particularly, to a joint pipe cover for a corner or the like that can accommodate and protect pipes and wires connected from an indoor unit or the like of an air conditioner to an outdoor unit or the like. .

  Conventionally, an elbow-type piping cover used for a corner portion has been proposed (for example, Patent Document 1). This elbow-type piping cover is used as an elbow-type piping cover for an air conditioner or the like disposed along an inner wall surface or an outer wall surface of a building, and as shown in FIG. The upper cover divided body 40 and the lower cover divided body (not shown) are combined. Further, the upper cover divided body 40 and the lower cover divided body are further divided into a first half 41 and a second half 42, and the first half 41 and the second half 42 are partially overlapped at the end portions. And are connected so as to rotate at an arbitrary bending angle.

  However, such an elbow-type piping cover 43 requires the first and second halves 41 and 42 of the upper and lower cover divided bodies, and a shaft portion (not shown) that enables connection and rotation thereof, which is complicated. The number of parts having a large shape increases, and the strength itself decreases because of the movable part. Moreover, the complicated assembly operation | work which assembles these will be required, and the increase in manufacturing cost will be caused. Therefore, an inexpensive elbow pipe cover cannot be supplied. Furthermore, since the elbow-type piping cover 43 itself has a movable part, there is a problem that the bent shape of the elbow-type piping cover 43 deviates from a predetermined angle at the time of attachment, and fixing of the attachment angle becomes complicated.

  On the other hand, as a wiring cover for an air conditioner or the like, an accessory cover that is connected to a linear cover and imparts a gradient has been proposed (for example, Patent Document 2). As shown in FIG. 5, the attached cover 50 is formed by combining a bent half split cylindrical upper cover divided body and a lower cover divided body 51, and a connection port 53 into which the linear cover 52 is inserted. Is formed of a material that can be deformed outward so that it can be connected at an angle to the opening direction.

However, in the accessory cover 50, the shape of the connection port 53a is deformed depending on the insertion angle of the linear cover 52. There is a gap in Further, when this gap becomes large, a step of closing the gap with a putty or the like is required, which complicates the work and requires a closing member such as a putty, resulting in an increase in attachment cost.

  The present invention has been made in view of the above problems, and can be easily and easily connected to, for example, a straight piping cover, regardless of the material and shape of the joint piping cover, and the straight piping cover. Can be changed to an arbitrary inclination, and the gap between them can be kept to a minimum, and the gap can be closed with a putty etc. An object of the present invention is to provide a joint pipe cover that can be easily attached while avoiding the work to be performed.

  The present invention provides a joint pipe cover having connection ports for connecting a pipe cover at both ends, wherein the connection port can change the insertion angle of the pipe cover inserted into the connection port. It is characterized by being formed so that the inner diameter becomes larger toward the back side of the cover.

  Further, the present invention is characterized in that the joint pipe cover is formed such that two connection port surfaces are substantially orthogonal or intersect at an angle of 60 to 75 °.

  Furthermore, the present invention is characterized in that the above-described joint pipe cover is provided with at least one projecting restriction portion for restricting the insertion angle and / or the insertion dimension of the pipe cover inside the vicinity of the connection port.

  Moreover, the present invention is characterized in that, in the above-described joint pipe cover, the protruding restriction portion has a shape capable of regulating different insertion angles and / or insertion dimensions of the pipe cover.

  Furthermore, the present invention is characterized in that, in the joint pipe cover, all or a part of the inner peripheral edge portion is chamfered at the distal end portion of the connection port.

According to the present invention, for example, when connecting a piping cover such as a straight line (hereinafter referred to as a “straight piping cover”) to the piping cover for a joint according to the present invention, the outer circumference of the same size as the connection port. If the straight piping cover having a diameter is selected, the inner diameter increases toward the back side of the connection port so that the insertion angle of the inserted linear piping cover can be arbitrarily tilted and changed. Therefore, a large allowable range in the connecting direction of the linear piping cover can be secured. That is, the linear piping cover can be inclined at a large angle. Therefore, for example, a drain gradient of an air conditioner or the like can be easily ensured. In addition, it is possible to easily cope with a straight line deviation at the time of execution of piping, and further, at the connection port, the gap between the straight pipe cover and the joint pipe cover can be minimized, and the gap can be reduced with a putty etc. It is possible to avoid the trouble of closing the cover, and the attachment work can be easily performed.
In particular, when both of the connection ports at both ends are formed so that the inner diameter increases toward the back side, the insertion angle as described above in any of the linear piping covers inserted into the connection ports. Can be changed, that is, the linear piping cover can be inclined, and the workability becomes more advantageous.

  In addition, when the two connection port surfaces are substantially orthogonal to each other or formed to intersect at an angle of 60 to 75 °, the joint piping cover adapted to the expected inclination angle of the linear piping cover; It is possible to connect the straight piping cover more easily and stably.

  Further, in the case where at least one protrusion restricting portion for restricting the insertion angle and / or the insertion dimension of the linear pipe cover is provided inside the vicinity of the connection port, the linear shape is formed at an arbitrary angle and at an arbitrary insertion dimension. The piping cover can be stably fixed by the joint piping cover.

  In particular, when the projecting restricting portion has a shape that can regulate different insertion angles and / or insertion dimensions of the linear piping cover, the insertion angle and the insertion dimension of the linear piping cover are equal to the linear piping. Even if it is determined at the installation site of the cover, it is possible to easily attach the linear piping cover with an appropriate insertion angle and insertion dimension.

  In addition, when all or part of the inner peripheral edge portion is chamfered at the tip of the connection port, the angular runout of the linear pipe cover can be increased without changing the size of the connection port. It is possible to take.

  Embodiments of the joint pipe cover of the present invention will be described in detail with reference to the drawings.

  In this specification, in order to distinguish from the joint pipe cover of the present invention, the pipe cover connected to the joint pipe cover is referred to as a “linear pipe cover”, but this pipe cover extends in a straight line. It includes not only those that are provided but also those that extend in a curved or bendable shape.

  In this embodiment, as shown in FIG. 1, the joint piping cover 10 includes a cover body 12 that is bent at approximately 90 ° and has connection ports 11 at least at both ends.

  The cover main body 12 can be formed of a material usually used for a pipe cover, for example, a slightly hard material or a deformable slightly soft material according to the thickness.

  The cover main body 12 may be integrally formed so as to surround the entire periphery of the linear piping cover, but is divided into halved shapes, etc. for ease of mounting on the linear piping cover, for example, It is preferably divided into two.

  The bent portion 12a on the outer side of the cover body 12 may be refracted at approximately 90 °, for example, corresponding to the connection state of the linear pipe cover 13, but for example, an arc shape having a radius of about 100 to 1000 mm. It is preferable that it is round and bent. Further, the inner bent portion 12b may be refracted in the same manner as the outer bent portion 12a, but it is preferable that the inner bent portion 12b be bent and rounded. Specifically, both the outer and inner bent portions 12a and 12b can be round with an arc shape having a radius of about 200 mm.

  The connection ports 11 formed in the cover body 12 may be formed at one or more other locations as long as they are formed at least at both ends. The connection port 11 is preferably set to a size that is the same as or slightly larger than the outer periphery of a normal pipe cover 13 to be connected, and may have an inner periphery of about 100 to 1000 mm, for example. . From another point of view, it is formed to have a dimension of about 10 to 200 mm (radius in the case of a circle, width in the case of a substantially rectangular shape, length of a major axis or a minor axis in the case of an ellipse). be able to. Specifically, a substantially circular connection port 11 having a radius of about 30 mm can be formed. Two or more connection ports 11 having the same size may be formed in the cover body 12 or two or more connection ports 11 having different sizes may be formed.

  Moreover, in the piping cover 10 for joints of this Example 1, when the connection port 11 formed at both ends closes the end of the connection port 11, that is, when the connection port surface is extended, the connection port surface is As shown in FIG. 1, they are formed so as to be substantially orthogonal. However, the connection port surfaces may intersect so as to have an angle of about 85 to 95 °, for example, or the connection port surfaces may be formed substantially in parallel. In the case of being substantially parallel, the two pipe covers are connected in a straight line via the joint pipe cover. However, when installing a pipe cover, if it is necessary to have a small gradient instead of a steep gradient at a predetermined location, it was intended to be arranged in a straight line, but it was slightly inclined. In dealing with such a case, it is possible to easily adjust the arrangement of the piping cover. In addition, when the pipe is extended from the room through the wall surface to the outdoor wall surface, and the pipe cover is attached in the horizontal direction on the window using a joint that covers the wall through hole and the pipe, a drain gradient can be easily provided. .

  The cover body 12 is formed so that the inner diameter (or inner circumference) increases from the connection port 11 toward the back side. In this case, the increase in the inner diameter may increase linearly or may increase in a curved manner, that is, increase in roundness or bulge so as to form a convex portion in the outward direction. The degree of increase is not particularly limited, but it depends on the outer circumference or dimensions (diameter, width, etc.) of the linear piping cover inserted into the connection port 11, but the linear piping cover is about ± 5 °. It is preferably set so that it can be inclined at a range of angles. Specifically, when the connection port 11 has a substantially circular shape with a radius of about 30 mm, the portion entering the back side of about 20 mm from the connection port 11 is inclined so as to have a radius of about 32 mm. it can. In addition, only one or both may be sufficient as the connection port which becomes large in such an internal diameter.

  It is preferable that the cover main body 12 has a projecting regulation portion 14 that can regulate the insertion angle, the insertion dimension, or both of the linear piping cover 13 inside the vicinity of the connection port 11. The position, number, size, shape, etc. of the projecting restricting portion 14 depend on, for example, the size of the straight piping cover 13 to be connected, the size of the cover body 12 itself, the size of the connection port 11, etc. Can be adjusted as appropriate. For example, when the connection port 11 has a radius of about 30 mm, as shown in FIG. 1, the protruding restriction portion 14 is near the center of the connection port 11 and enters the back side by about 20 mm from the connection port 11. It can be formed in a rectangular shape of about 20 mm × 8 mm, one for each connection port 11.

In the cross-sectional view shown in FIG. 1, the projecting restricting portion 14 may be formed in the vicinity of the central portion of the connection port 11, but may be formed at a position deviated from the central portion, or both side portions. It may be formed.
Further, the number may be only one, but may be two, three, four, or the like.
Furthermore, the size should just protrude slightly inward in order to determine the insertion angle and insertion dimension of a piping cover. For example, the surface having an area of about 10 to 500 mm ^{2 only} needs to face the connection port.

  Examples of the shape of the projecting shape restricting portion 14 include various shapes such as a planar shape such as a circle, an ellipse, and a polygon, and a curved surface shape, a bent (uneven) shape, and a refractive shape. In particular, a rectangular planar shape is preferable because the inserted linear piping cover can be easily and stably fixed. Further, for example, in the case where the cross section shown in FIG. 1 is refracted into a V shape, the inserted pipe cover is moved along a predetermined angle, that is, along two sides (surfaces) of the V shape. It is preferable that the pipe cover can be attached to each other and the pipe cover can be stably fixed in two directions. Further, as shown in the cross section shown in FIG. 1, in the case of a curved surface shape, even when the insertion angle of the pipe cover is not determined in advance, the linear shape is in contact with the curved surface in each direction. By bringing the pipe cover into contact, the linear pipe cover can be stably fixed at various insertion angles.

  The insertion angle and the insertion dimension of the linear pipe cover regulated by the projecting regulation part 14 depend on the shape of the cover body 12 and the connection port 11 (circular, elliptical, rectangular, substantially rectangular, etc.). For example, an angle of about 70 to 120 °, preferably an angle of about 80 to 100 °, more preferably an angle of about 85 to 95 °, and a length of about 5 to 50 mm.

  Such a joint piping cover 10 can be attached to a wall surface by screwing to the wall surface using, for example, a screw hole 15b formed in a cover body 12 that is divided in half in a half shape. At this time, the pipe cover 13 is inserted from the connection port 11, the cover body 12 and the pipe cover 13 are adjusted so that they can be attached at a predetermined angle, the positions are determined, and both are fixed with screws or the like. Further, when the joint pipe cover 10 is divided into two halves, both can be integrated using the screw holes 15a.

  In this embodiment, as shown in FIG. 2, the joint pipe cover 20 includes a cover body 22 having connection ports 21 at least at both ends.

  The cover main body 22 is divided into two halves so as to surround the entire periphery of the linear piping cover 23. The bent portion 22a on the outer side of the cover body 22 may be refracted corresponding to the connection state of the linear pipe cover 23. For example, the bent portion 22a is rounded so as to have an arc shape with a radius of about 100 to 1000 mm. It is preferable to be bent. Further, the inner bent portion 12b may be refracted, or may be rounded and bent. The size of the joint pipe cover 20 itself is not particularly limited. For example, the length of the string connecting the arc-shaped ends of the outer bent portion 22a can be about 100 to 500 mm. Specifically, in the joint pipe cover 20 of FIG. 2, the outer and inner bent portions 22a and 22b are both rounded so as to have an arc shape with a radius of about 200 mm, and the outer bent portion is bent. The length of the string connecting both ends of the arc shape of the portion 22a can be formed with a size of about 140 mm.

As in the first embodiment, the connection port 21 formed in the cover body 22 is preferably set to the same size as or slightly larger than the outer periphery of the normal pipe cover 23 to be connected. . Specifically, a substantially circular connection port 21 having a radius of about 30 mm can be formed.
Further, in the joint pipe cover 20 of the second embodiment, the connection ports 21 formed at both ends have a surface that closes the endmost portion of the connection port 21, that is, when the connection port surface is extended, For example, they can be crossed so as to have an angle of about 60 to 75 °. Specifically, the angle is set to an angle (approximately 67.5 °) represented by C in FIG.

  The cover body 22 is formed so that the inner diameter increases from the connection port 21 toward the back side. The degree to which the inner diameter increases in this case is not particularly limited, and depends on the outer circumference or diameter of the linear piping cover inserted into the connection port 21, but the angle of the linear piping cover in the range of about 45 °. It is preferable that the setting is made so that Specifically, the cross section parallel to the connection port 21 can be set so as to have a radius of about 33 to 34 mm at a portion about 20 mm from the connection port 21.

  It is preferable that the cover main body 22 has a protruding restriction portion 24 that can restrict the insertion angle, the insertion dimension, or both of the linear piping cover 33 inside the vicinity of the connection port 21. The formation position, number, size, shape, and the like of the projecting restricting portion 24 are determined depending on, for example, the size of the linear piping cover to be connected, the size of the cover body 22 itself, the size of the connection port 21, and the like. It can be adjusted appropriately. For example, when the connection port 21 has a radius of about 30 mm, two can be formed on both sides inside the connection port 21 in the cross section as shown in FIG. The insertion angle and the insertion dimension of the linear piping cover 23 regulated by the projecting regulation part 24 are, for example, an angle of about 55 to 140 °, 5 to 5, depending on the shape of the cover body 22 and the connection port 21. The length is about 50 mm.

  In the second embodiment, a chamfered portion 21b is formed on the inner peripheral edge portion 21a at the foremost portion of the connection port 21 (see FIG. 3). The chamfered portion 21b can swing the insertion angle of the linear pipe cover 23 inserted into the connection port 21 without changing the size and shape of the cover body 22 and the connection port 21, and can be inserted. Even if the swing of the angle is increased, the generation of a gap between the connection port 21 and the pipe cover 23 can be prevented. The chamfered portion 21b may be formed on all of the inner peripheral edge portion 21a of the earliest portion of the connection port 21, but only the inner peripheral edge portion 21a that abuts when the pipe cover 23 changes its angle is provided. It may be broken.

  When such a joint pipe cover 20 is attached to a wall surface, the angle and position of the cover body 22 and the pipe cover 23 are adjusted using a screw hole 25a formed in the cover body 22 that is divided into two parts in a half shape. While determining the mounting position, fix them.

  For example, when connecting the pipe cover 23 at about 135 °, the pipe cover 23 is inserted from the connection port 21 until it comes into contact with the protruding regulation portion 24 formed on the inner side surface of the cover body 22, and The side surface of the cover 23 is brought into contact with the inner side surface of the cover main body 22 (the angle represented by D in FIG. 2 and adjusted to 135 °) to be stabilized, and is fixed using screws or the like. Thereby, the piping cover 23 can be connected at an angle (substantially 135 °) represented by A in FIG.

  Further, when connecting the pipe cover 23 at about 90 °, similarly, the side surface of the pipe cover 23 is brought into contact with the outer side surface of the cover body 22, and the projecting restricting portion 24 formed on the outer side surface is contacted. What is necessary is just to insert the piping cover 23 until it contact | abuts. Thereby, the piping cover 23 can be connected at an angle (substantially 90 °) represented by B in FIG.

  As a modified example of the joint pipe cover of the second embodiment, the protrusion-like restricting portion 24 is, for example, a stepped shape 24a as shown in A portion of FIG. 3 or shown in B portion of FIG. Thus, it is good also as what 24b arrange | positioned so that it may overlap in the insertion direction of a linear piping cover. With such a shape, the angle of the pipe cover inserted into the connection port 21 can be arbitrarily and stably fixed.

  In addition, each component demonstrated in the said Example 1 and 2 can be taken out arbitrarily and can be combined.

  The pipe cover for joints of the present invention is not only for air conditioner pipes, but also for various pipes such as water pipes, hot water pipes, gas pipes, etc., and as a decorative cover for electric wires, etc. It enables joints with various shapes such as refractive shapes, and can be used in a wide range of fields.
