Description

[Detailed description of the invention] This invention relates to a device for attaching a sash to a sash.The purpose of this invention is to easily attach and remove the sash, and to securely temporarily hold the sash so that the sash does not fall off before panel installation. The purpose of the present invention is to provide a mounting device.

As a conventional sash attachment device,
As shown in Utility Model Publication No. 53-48514,
There is a clip that fits the engagement strip of the sash frame into the engagement part of the sash frame to prevent it from slipping. The advantage of this device is that once the rim is attached, it is difficult to remove, so it will not get dislodged or fall off, but on the other hand, if the rim is long, there will be problems with extrusion tolerances, twisting, warping, etc. when the rim is manufactured by extrusion molding. This makes it difficult for the engagement strip of the ridge to enter the engagement portion of the sash frame. Another drawback was that once the rim was attached to the sash, it was difficult to remove, making it difficult to replace panels such as glass.

Furthermore, as seen in the invention of Japanese Utility Model Application Publication No. 54-38316, when the engagement strip of the ridge is engaged with the engagement part of the sash frame, the ridge is slid and engaged, and the There is a rim attachment device that fixes the rim by attaching a panel.
The advantage of this device is that the attachment of the ridge is smooth and easy, but on the other hand, the ridge is unstable and easily comes off unless the panel is attached.

For items that are continuous and placed at high places, such as ridges attached to curtain walls, it is necessary to be able to install the ridges smoothly and easily, and to ensure that the ridges can be temporarily held in place before installing the panel. Otherwise, the rim may fall off, which is extremely dangerous. In this sense, the conventional rim attachment devices have advantages and disadvantages, and do not fully satisfy the intentions of the industry.

Thus, this invention was devised to eliminate the above-mentioned drawbacks of the conventional methods, and it is possible to install smoothly and without the need to attach panels, even for high and continuous items such as the raised edge of a curtain wall. Another object of the present invention is to provide a rim attachment device for a sash that can securely temporarily hold the rim and prevent the rim from falling off.

This invention will be explained below based on embodiments shown in the drawings. FIG. 1 is a cross-sectional view showing a rim attachment device for a sash according to this invention. In FIG. 1, the symbol A indicates a sash frame. The sash frame A includes a mullion part 1 having a rectangular cross-section and a hollow part, and a connecting part 2 extending from the mullion part 1 toward the outdoor side.
and a substrate 3 that is joined to the connecting portion 2 at right angles. Ribbed edge fitting grooves 15 and 1 are provided at both ends of the side surface of the mullioned portion 1 where the connecting portion 2 extends.
5 is formed, and engaging recesses 4, 4 are provided, respectively, which open outward from the protruding pieces protruding from the inner wall. In addition, at the center in the width direction of the connecting portion 2, engagement recesses 4', 4' are provided in the ridge fitting portions on both sides of the connecting portion 2, respectively, which are bent into an L-shape toward the outdoor side.

Further, in FIG. 1, the symbol B indicates a crimped edge. The ridge B is composed of a generally U-shaped ridge main body 5 and a spacer support leg 7 projecting from one end 6 of the ridge main body 5. Engagement strips 9 and 9' that engage with the engagement recesses 4 and 4' of the sash frame A are provided at one end 6 and the other end 8 of the rim body portion 5, respectively.

The ribs having such a structure are arranged symmetrically on the left and right with the connecting portion 2 of the sash frame A as a boundary.

By the way, the symbol C indicates an elastic member made of soft rubber or soft synthetic resin.

The elastic member C is located between the spacer support leg 7 of the ridge B and the inner wall 10 of the base plate 3 of the sash frame A.
It is arranged with a biasing force in the direction of arrow P. Therefore, the engagement strips 9, 9' of the ridge B are connected to the sash frame A.
firmly engages the engagement recesses 4, 4' of the sash frame A.
will be temporarily held.

In the above, the attachment of the rim B and the panel D will be explained. First, the elastic members C, C are arranged on the inner wall 10 of the substrate 3 of the sash frame A, and then, while pressing the elastic members C, C with the spacer support legs 7, 7, the engaging strips 9, 9' are engaged with the engaging recesses 4, 4' of the sash frame A, and the ridges B, B are temporarily held in the sash frame A (see FIG. 3). Next, press edge B,
Fit the end of the panel D into the panel mounting grooves 12, 12 formed by surrounding the panel holding edges 11, 11 of B and the inner wall 10 of the board 3 of the sash frame A, and fit the end of the panel D into the panel mounting grooves 12, 12. spacer 13,
13 and fix the panel D to the sash frame A via the watertight materials 14, 14. Therefore, the attachment and fixation of the rim B and the panel D is completed.

Thus, the rim attachment device according to this invention achieves the effects described above.

(1) Temporary holding and attachment of the ridge can be done smoothly and easily since it is only necessary to use the biasing force of the elastic member to engage the engagement strip of the ridge and the engaging portion of the sash frame. . Moreover, when removing the ridge, the ridge can be easily removed by pressing the ridge, compressing the elastic member, and releasing the engagement.

(2) Even before the panel is attached, the rim can be reliably temporarily held in the sash frame, and the engagement strip of the sash and the engaging portion of the sash frame are firmly engaged by the biasing force of the elastic member; The press edge will not shift,
It won't come off again.

(3) Since the sash frame can be temporarily held on the sash frame at the stage of manufacturing the sash frame, etc., workability on site is improved and safety is ensured when working on site at a high position.
