Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a cross member of a window unit having an outlet for blowing out conditioned air such as cool air or warm air from the cross member constituting the window frame.

Prior Art As shown in Japanese Unexamined Patent Publication No. 59-27149, the cross members constituting the curtain wall unit are hollow, and an outlet is formed in the upper wall of the cross member, and conditioned air is supplied from the outlet. There is a known device that air-conditions the room by blowing air out inside the curtain wall unit.

Problems to be Solved by the Invention The air outlet of such a cross member is a blower unit in which a plurality of slit-shaped notches are provided at intervals in the longitudinal direction on the upper wall of the cross member, and each of the notches has an air outlet. Since it is not possible to form air outlets over the entire length of the cross member in the longitudinal direction, conditioned air is blown out from multiple positions spaced apart in the longitudinal direction, so the blowout distribution of conditioned air is Due to the unevenness in the longitudinal direction, efficient indoor air conditioning cannot be performed, and since multiple notches are formed in the upper wall of the cross member, the strength of the cross member decreases and machining is troublesome. Become.

Therefore, the present invention provides a cross member with an outlet that provides an outlet over the entire length in the longitudinal direction so that the distribution of conditioned air is uniform in the longitudinal direction, and eliminates the need for troublesome machining of notches. The purpose is to provide

Means and operation for solving the problem The upper wall constituting the hollow part continuous in the longitudinal direction has a substantially upward U-shape and opens upward in the middle part toward the indoor side. and an upper locking piece 8 at the upper part of the indoor side opening edge of the recessed part 80.
2, and a cover body 84 attached to the recess 80 of this cross member, and the cover body 84
has a shape having an upper horizontal piece provided with an upper locking piece 85 that engages with the upper locking piece 82, and the upper locking piece 8
5 is engaged with the upper locking piece 82 so that the upper horizontal piece is at the same height as the indoor side from the recess 80 on the upper side wall of the cross member, and the upper horizontal piece and the outdoor opening edge of the recess 80 form a slit. A shaped air outlet 64 is formed in the longitudinal direction, and a hollow portion and the recess 80 are formed closer to the indoor side than the air outlet 64 in the bottom wall of the recess 80 of the cross member.
A horizontal member having an air outlet in which a communication hole 81 is formed to communicate with each other.

As a result, the conditioned air that has flowed into the hollow part of the cross member can be blown out from the entire longitudinal direction of the cross member, and the air outlet distribution is uniform in the longitudinal direction, allowing efficient air conditioning. It is not necessary to process the communication hole 81 in the bottom wall of the recess 80, and the communication hole 81 does not need to be cut out with the cover body 84 removed, and its strength is reduced. Since the cover body 84 can be attached and detached by engaging and disengaging the upper locking piece 82 and the upper engaging piece 85, it can be harmonized by attaching cover bodies 84 of different dimensions and changing the width of the air outlet 64. Air blowout amount can be adjusted. Furthermore, the interior side of the cover body 84 is at the same height as the recess 80 in the upper side wall of the cross member, and when viewed from the interior side, the cover body 84 and the upper wall appear to be flush, giving a good appearance. 81 is shifted toward the indoor side from the air outlet 64,
Since the conditioned air flowing into the recess 80 through the communication hole 81 hits the cover body 84 and is blown out from the outlet 64, even if the communication hole 81 is small, the conditioned air can be blown out uniformly from the outlet 64 in the longitudinal direction.
