Abstract

PURPOSE:To facilitate fitting and detaching a joint part, thereby enhance workability and facilitate inspection and maintenance, by a construction wherein a 'Velcro(R)' tape with a large width is superposed on and engaged to another 'Velcro(R)' tape adhered to an end part of a duct. CONSTITUTION:The 'Velcro(R)' tapes 2a, 2b are adhered to end joint parts of air conditioning ducts 1a, 1b along the whole circumference of the joint parts. Mount bases 5 attached to the ducts 1a, 1b are mounted to a car body or structure by screws or the like (bolts, rivets), and the 'Velcro(R)' tap 3 with a large width is superposed on and engaged to the 'Velcro(R)' tapes 2a, 2b preliminarily adhered to the duct joint parts, whereby the ducts 1a and 1b are coupled to each other to function as an air conditioning duct. Alternatively, the air conditioning ducts may be coupled to each other by use of the 'Vel cro(R)' tape 3 with a large width, before being attached to the vehicle body or structure.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air conditioning duct, and more particularly to an air conditioning duct that facilitates installation of the air conditioning duct and is suitable for simplifying the duct structure.

[Conventional technology]

The conventional device, as described in Japanese Utility Model Publication No. 63-7566, was composed of a flange provided on both connecting ducts, and a tightening member fitted on the outer periphery of this flange to connect both duct flanges.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not take into consideration the workability of the duct connection portion, and there is a problem in that it takes time to install the duct. In addition, in the conventional technology, a flange is provided at the duct connection part and the outer periphery of the seven flanges is attached by tightening, so there is no consideration given to the increase in the number of parts and the simplification of the duct structure, which increases the cost of the duct. There was a problem with up.

The present invention aims to facilitate the installation work of air conditioning ducts, and further aims to reduce costs by simplifying the duct structure.

(Means for solving eta) In order to achieve the above purpose, a mating tape is attached in advance to the ends of both ducts to be connected, and a wide mating tape for connecting both ducts is then applied over the entire length. It is laminated over the circumference.

[For production]

The interlocking tape attached to the end of the duct.

By overlapping and pasting another wide interlocking tape, the duct is completely connected and the tangential portion is closed, so it can function as an air conditioning duct.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

la and lb are the air conditioning ducts to be connected, respectively, 20.2
b is the interlocking tape affixed to the ends of these air conditioning ducts la and lb in advance or during work; 3 is the air conditioning duct 1
, a medium wide interlocking tape which is bonded over the above interlocking tapes 2a and 2b to join the air conditioning ducts 1a and 1b during the second contact M; 4 is a tape that connects the cold or warm air blown from the air conditioner with the air outside the duct; 5 is a mounting foot for mounting on the vehicle body or structure.

In the figure, interlocking tapes 2a and 2b are pasted around the entire circumference of the air conditioning duct la and lbO end connections.

The mounting feet 5, which are attached to the vehicle body or structure and the air conditioning ducts la, lb, are attached by using screws, etc. (bolts, rivets), and are attached to the tops of the interlocking tapes 2a, 2b that are pre-affixed to the duct connections. By overlapping and pasting the wide interlocking tape 3, the air conditioning duct l
a and lb are combined and have the function of an air conditioning duct. Note that the wide interlocking tape 3 may be laminated and attached to the vehicle body or structure with the air conditioning duct combined.

According to this embodiment, since the connecting portion can be attached very easily, there is an effect that the workability of air conditioning duct construction can be improved. In addition, the connection part can be easily removed, so
Periodic maintenance and inspection of ducts becomes easier. Furthermore, unlike conventional technology, a flange is provided at the end of the duct and the outer periphery is not tightened with a tightening ring, so there is no need for unnecessary work on the air conditioning duct, and the tightening ring can also be eliminated. It has the effect of being able to be transformed into

FIGS. 3 and 4 show other embodiments of the present invention.

If the lower surface of the air conditioning duct is a ceiling plate 6, such as in a railway vehicle, the air conditioning ducts la, lb and the ceiling plate 6 are designed to be removable, and the area shown in Fig. 4 is covered with interlocking tape 2m, 2b and Connect the air conditioning ducts Is and lb using wide interlocking tape 3, and if it is necessary to join the ceiling panels 6, use another method! ! By matching, an air conditioning duct can be constructed.

In this embodiment as well, the air conditioning duct can be easily connected and work efficiency can be improved.

〔Effect of the invention〕

According to the present invention, the air conditioning duct connection portion can be attached very easily, so that the workability is improved. Furthermore, since it can be easily removed, regular maintenance and inspection of the air conditioning duct can be easily performed.

Furthermore, since there is no need to process the duct connection portion, the duct structure can be simplified and the cost can be reduced.
