Description

[Detailed description of the invention] [Industrial application field] This invention combines vertical and horizontal stiles formed from extruded sections with connecting blocks made of synthetic resin.
Moreover, the present invention relates to a device for fixing a connecting block of an indoor fitting without a rubber doorstop to a vertical stile.

[Conventional technology]

Indoor fittings without rubber doorstops have a vertical stile whose basic cross-sectional shape is a U-shape, and an intermediate wall is provided between the two parallel outer walls of the cross-sectional shape, and the vertical stile and horizontal stile are Conventionally, a method using a connecting block is known as a means for combining the two. By the way, when combining frames with connecting blocks, the connecting blocks are fixed to each vertical frame, but there was a problem with the means for fixing them to the vertical frames. In other words, if you make a hole in the doorstop surface of the vertical stile, insert a screwdriver through the hole, and screw the connecting block to the intermediate wall, it will be easily fixed, but the hole drilled in the doorstop surface will remain, making it look like an indoor fitting. I'll lose it. As a means to solve this problem, for example, as described in Japanese Utility Model Application Publication No. 55-154283, a plate spring that expands by the rotation of a screw is provided on the connecting block, and the plate spring is fixed by the compression force of the plate spring, or other methods. Methods are also known, but these are constructed based on the idea of fixing them with screws that are not visible from the outside.

[Problem that the invention attempts to solve]

Although the solution described above uses screws and is easy to assemble. Considering the efficiency of mass production, there is a problem in that screwing takes time. This invention was developed from the above points of view to improve efficiency and to develop a device for fixing connecting blocks for interior fittings, with the aim of firmly attaching connecting blocks to vertical frames.

[Means for solving problems]

The connecting block fixing device for indoor fittings according to this invention has a vertical locking portion of a connecting block made of synthetic resin, which has a horizontal locking portion and a vertical locking portion that are housed within the respective ends of a horizontal stile and a vertical stile of an indoor fitting. A notch hole long in the height direction is provided at the end of the intermediate wall of the vertical stile to which the connecting block is attached, and the entrance part thereof has a constriction part narrower than the enlarged part at the back. , an engagement part with a narrow cross section that fits into the notch hole over its entire height from the entrance part is provided, and the engagement part has a narrow cross section that is wider than the squeeze part of the notch hole. It is constructed by providing a long strip portion to be crimped.

[Effect]

Therefore, by inserting the end of the intermediate wall of the vertical stile into the narrow cross-section engaging part provided in the vertical locking part of the connecting block, the engaging part fits into the notch hole and the connecting block The large strip part is compressed by the elasticity peculiar to synthetic resin at the squeezed part of the notch hole, and due to the repulsive force, the large strip part returns to the enlarged part and is latched to the squeezed part, so that the connecting block is fixed to the vertical frame integrally. It is something that will be done.

〔Example〕

As shown in Fig. 4, 1 is a vertical stile, 2 is a connecting block, 3 is a horizontal stile, 4 is an adjustment bar, and 5 is a sliding block, and the vertical stile 1, the horizontal stile 3, and the adjustment bar 4 are made of aluminum alloy. It is made of extruded shape material, and the vertical frame 1
has a U-shaped cross section, its parallel outer walls 6, 6 are integrally connected by an intermediate wall 7, and protrusions 8, 8 are provided at the open end edges of both outer walls 6, 6. A notch hole 9 is provided at the lower end. As shown in FIG. 2, this notch hole 9 includes a guide portion 10 that stands up from the lower end with an incline in a direction in which both edges approach each other, an enlarged portion 11 that spreads stepwise from the guide portion 10, and a guide portion 1.
0 and the enlarged part 11, and a narrow part 1 that rises from the enlarged part 11 with a width narrower than the width of the squeezed part 12.
It has 3. The horizontal stile 3 is a lower stile and has an H-shaped cross section, and as shown in FIG.
8 and engages inside the vertical stile 1, and engagement grooves 15, 15 are formed by projecting pieces parallel to the lower surface of the horizontal wall 14 of the horizontal stile 3.

The connecting block 2 is made of nylon 6, as shown in FIG. It has a vertical locking part 18 that fits inside.
The vertical locking part 18 is provided with an engaging part 19 having a narrow cross section that fits into the notch hole 9 provided in the intermediate wall 7 of the vertical stile 1 from the entrance thereof over the entire height thereof. As shown in FIG. 2, the engaging portion 19 has a large portion at its lower portion that is wide and has approximately the same width as the enlarged portion 11 of the notched hole 9 so as to be able to press against the squeezed portion 12 of the notched hole 9. The narrow part 1 of the notch hole 9 is provided at the upper part.
It has a strip part 22 that fits into the 3.

The structure of fixing the horizontal locking part 17 to the horizontal stile 3 in the connecting block 2 is as shown in FIGS. A through hole 24 is made in the side wall 14, and an adjusting screw 25 passing through the adjusting bar 4 and the smoothing block 5 is screwed into the vertical hole 23 of the connecting block 2 in the manner of cutting a tap.
Some of them penetrate through the through holes 24 and are fixed.

Furthermore, although the above-mentioned embodiment shows means for connecting the vertical stile and the lower stile as shown in the drawings, the upper stile is also connected in the same manner.

According to the above embodiment, only the notch hole 9 is formed in the intermediate wall 7 of the vertical stile 1, and the intermediate wall 7 is
By inserting it into the engaging part 19 with a narrow cross section provided on the vertical locking part 18 of the connecting block 2, the large strip part 21 provided on the engaging part 19 engages with the squeezed part 1 of the notch hole 9.
2, and the large strip part returns to its enlarged part due to the repulsive force and is latched to the squeezed part, so that the vertical locking part of the connecting block is integrally fixed to the vertical stile.

[Effect of idea]

The connecting block fixing device for indoor fittings according to this invention is formed by forming a notch hole at the end of the intermediate wall of the vertical stile with a squeezed part narrower than the width of the enlarged part at the back at the entrance of the notch hole, and The vertical locking part of the synthetic resin connecting block that combines the two is provided with an engaging part with a narrow cross section that fits into the notch hole over its entire height from the entrance part, and The portion is provided with a long strip portion that is wider than the squeeze portion of the notch hole and is pressed against the squeeze portion, and when the engaging portion is fitted into the notch hole, the long strip portion is compressed by the squeeze portion and returned to the expanded portion. The vertical locking part of the connecting block can be attached to the vertical locking part of the connecting block by inserting the end of the intermediate wall of the vertical stile into the narrow cross-section engaging part provided on the vertical locking part of the connecting block. This makes the fixing operation much easier and faster. In addition, as mentioned above, since the large strip is compressed by the compressed part and fixed by the repulsive force, the fixed state is strong, and the engagement part with a narrow cross section is provided on the middle wall of the vertical stile. By fitting into the notch hole, the intermediate wall is fixed to sandwich the vertical locking part of the connecting block, so that it can be connected against tension in the longitudinal direction of the horizontal stile fixed to the horizontal locking part of the connecting block. This will surely prevent the block from escaping.
