Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a device for mounting a cooling unit along the inner wall of the ceiling of a vehicle.

(Prior Art) In a vehicle such as a so-called one-box car, a cooling unit is provided along the inner wall of the ceiling. Conventionally, when installing such a cooling unit on the ceiling, for example,
As shown in Japanese Patent No. 53113, a bracket was fixed to the inner wall of the ceiling, and a cooling unit was screwed to this bracket.

(Problem to be solved by the invention) However, when attaching the cooling unit to the bracket, it is necessary to support the relatively heavy cooling unit and then secure it with screws. Therefore, a total of two or three workers are required, including one to support it and one to tighten the screws, resulting in a problem of poor workability.

Therefore, this idea solves the above problems and
The objective is to improve workability so that even a single worker can install the cooling unit.

(Means for Solving the Problems) In order to solve the above problems, a vehicle mounting device for a cooling unit according to the present invention is a cooling unit comprising a blower and an evaporator housed in a case having an intake hole and an outlet. In order to install the unit along the inner wall of the vehicle ceiling, there are mounting stays near the four corners of the upper part of the cooling unit.
In the mounting structure in which the inner wall of the ceiling is provided with a bracket for screwing the stay, a hook-shaped hook portion is provided protruding from one of two sets of parallel stays on either the front, rear, or left and right sides of the cooling unit. A temporary support portion is provided in which the hook portion is inserted and engaged at a position of the bracket corresponding to the hook portion, so that one side of the cooling unit can be temporarily supported.

(Function) Therefore, when installing the cooling unit, one side of the cooling unit is temporarily supported by engaging the hook part provided on the cooling unit with the temporary support part of the bracket, and the operator is required to attach the other side that is not temporarily supported. It can be supported and installed by one person.
