Description

[Detailed Description of the Invention] This invention relates to a hose piping case, and more particularly to a piping case for an insulated hose for water supply and hot water supply used in solar water heaters.

・Solar water heaters, which are becoming popular today, connect a heat collector installed on the roof or building, etc. and a heat storage tank installed inside the building with an insulated hose; When piping, the hose must be bent.

However, when piping a hose to the above-mentioned locations, if the hose is bent more than necessary, the flow of water and hot water supply will be obstructed, which is undesirable.

□ ・ ,”・ .Therefore,
Conventionally, when piping a part of a corner, the actual situation is to apply a reinforcing material to a part of the corner, or to wrap the hose in a bellows cylinder. Even in this configuration, it is difficult to maintain the center and center bending radii at a radius that does not impede the flow when piping.

□ ..., 1
h Furthermore, the connection between the curved piping case and the straight case is
This creates a gap between the two cases, making it difficult to install the piping neatly.

. Therefore, the present invention allows piping to be performed while maintaining the bending radius of the hose, reliably preventing the hose from breaking or being damaged, and making it possible to connect the cases to each other reliably and easily. It provides a case.

The hose piping case of the present invention that achieves this purpose has two features:
It consists of a long frame with a chevron-shaped cross section that can store book hoses in parallel, and a flexible lid frame that covers the top opening of the frame. , is provided with a locking protrusion that locks and holds the lid plate, and a retaining piece 5 that is curved in an arc shape is formed protrudingly on the inside, and a rigid connecting rod is inserted inside, and the frame body is It is characterized by having circumferential cuts made at equal intervals in the longitudinal direction, except for the locking protrusions at the upper portions of both sides.

In the present invention, the frame that can house the hose may be made of metal (for example, 4 aluminum plates, iron plates, etc.) or plastic. If it is made of metal, it is a long strip! ；Is it possible to press the part corresponding to the cut along the longitudinal direction? Punching with 1. ,
The frame is formed by bending it into a cross-sectional shape, but if it is made of resin, the frame body with a cross-sectional shape with cuts is molded all at once.

,・1.1.5. , knee 5 , . ．． : Also, on the upper sides of both sides of the frame body, there are locking protrusions located on the outside to lock and hold the lid plate, and on the inside, a presser piece curved in an arc shape is formed along the longitudinal direction. In addition, a connecting rod having rigidity to maintain the bent state of the frame body, such as a metal rod rod made of iron, aluminum, etc. that can be bent, is inserted into the holding piece, and the connecting rod is a straight rod. It is used to connect to the frame.

In addition, the circumferential cuts made on the frame are for bending the hose stored inside without folding, and these cuts allow the locking protrusions provided on the tops of both sides of the frame to be bent. There are notches formed on the curves except for the curves.

The lid plate that covers the upper opening of the frame is made of a flexible synthetic resin material so that it can be attached to the frame in a manner that fully corresponds to the curved shape of the frame.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
A is a frame body, B is a cover plate that covers the top opening of frame body A,
Both of these constitute a piping case.

・□゛Frame A is made of hard polyvinyl chloride resin and is formed into a long cross-sectional shape that can accommodate two hoses 7.7' in parallel, and is placed on the upper outer side of both vertically standing walls. Locking protrusions 1, 1' are formed protrudingly on the sides, and presser pieces 2, 2' curved in an arc are integrally molded on the inner side opposite to the locking protrusions 1, 1'. , presser piece 2・-2
Connecting rods 3, 3' made of rigid metal rods are inserted and fixed in the inner portions.

' ・Also, in the peripheral wall of the frame A except for the locking protrusions 1゜1' on both the left and right sides, circumferential cuts 4 are cut out at equal intervals in the longitudinal direction, and each of these cuts Enlarged holes 5 are continuously formed at the upper ends of both sides of the hole 4 to prevent concentration of stress.

, ゛□ The width of the cutout 4 made in the frame A shall establish a bending radius within a range in which the hose 7.7' does not break.

) Lid plate B, like the frame A described above, is molded from a flexible hard vinyl chloride resin, and has locking protrusions 1 and 1' of the frame A on both left and right sides thereof. A hooking portion 6.6'= is formed to protrude.

In the figure, 8. is a screw insertion hole mini'9 for fixing frame A to the wall and roof surface. is a double-sided adhesive tape attached to the bottom surface of frame A, and is used to attach frame A during piping construction in this case. It can be temporarily fixed to a wall etc.

・□、・□、−. - 10 is a cord for the thermostazod, 11 is a piece to prevent the thermostat from falling off, 12 is a straight piping case, 13 is a connection cover, and 14 is a screw for fixing the frame A.

In addition, if the straight piping case 12 has the same shape as the frame body A and has a structure in which the pin is not inserted into the holding piece, the protruding end of the connecting rod 3.3' that is inserted through the frame body of the present invention. By inserting the pipe into the frame of the straight line piping case, the case and the straight line case can be connected in a straight line.

When the hoses 7 and 7' are housed and piped in a closed case as described above, the pipes are first installed on the roof using the straight piping case 12, and from the tip of the roof to under the eaves the connecting rod 3 is connected to the straight piping case 12. , 3' or a separate connection plug, etc. to connect the frame A of the present invention, and then bend the frame A to the underside of the eaves using the cutouts 4 to connect the hose 7.7'
Piping can be connected without causing any creases.

Furthermore, the curved shape is maintained by a connecting rod inserted into the holding piece 2.degree. 2' of the frame A.

- Since the hose piping case according to the present invention has the above structure, it exhibits the following excellent effects.

□(1) Piping can be done with the hose stored, and the curved piping can be done within the range where the hose does not break.

(2) The two hoses, the water supply hose and the hot water supply hose, are connected together, and the frame is rigid and connected to ensure that the predetermined bent shape is maintained, and that it is not affected by wind and snow. The installation can be maintained stably for a long time without damage.

□. (Since the bending operation for case 31 can be performed on site, it is possible to install the piping according to the installation location.

・(4) If the tip of the connecting rod in the holding piece that maintains the curved shape of the frame protrudes from the side edge of the frame and is inserted into the holding piece of the straight piping case, the cases can be connected linearly to each other. You can.
