Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sash mounting dust guide (hereinafter simply referred to as a dust guide) used when a sash is mounted on a building frame.
[0002]
[Prior art]
To attach the sash to the building frame, a sash framed in a rectangular shape is inserted into the frame opening, and the sash is fixed to the frame by screwing or the like.
[0003]
[Problems to be solved by the invention]
Therefore, it is necessary that a gap (chile) exists between the outer peripheral surface of the sash and the inner peripheral surface of the housing opening to facilitate the insertion of the sash into the housing opening.
On the other hand, due to the presence of the dust, the conventional mounting method requires labor and many fixing members for fixing the sash inserted into the housing opening, and the mounting work becomes complicated, and the mounting position of the sash is The center of the building was easily biased in either the left or right direction.
[0004]
The difficulty of the conventional method will be specifically described with reference to FIGS. FIG. 4 is a partial cross-sectional view showing an example in which the frame is made of wood. 1A is a left column that constitutes the casing, 2A is a left vertical frame of the sash SA, GA is a dust when the sash is fitted into the casing opening 3, and is about 10 mm. Therefore, there is an advantage that the sash SA can be easily inserted into the housing opening 3. However, since the size of the dust is large, the stability of the inserted sash is low. Before the sash is fixed to the housing, the wooden padding 4 having the same size is interposed between the left and right dust in several vertical directions. Was then temporarily fixed, and then the wood screws 5a, 5b and the like were screwed into the pillar 1A from the vertical frame 2A and fixed permanently.
However, since it is difficult to match the thickness dimension of the wooden filling 4 with the Chile dimension GA, it is difficult to fix the sash SA to the center of the housing opening 3, and accordingly, the screw 5 b outside the vertical frame is fixed. There was a risk that the screwing position would be inappropriate. In addition, it is troublesome to secure equal dust on the left and right sides by packing the wooden filling 4 on site, and there is a problem that the construction takes time.
[0005]
FIG. 5 is a partial cross-sectional view showing an example in which the housing is a steel structure. 1B is the left steel column which comprises a housing, The sash fixing member 6 is screwed beforehand by this. When attaching the sash SB, the vertical frame 2B is inserted into the housing opening 3, and the mounting edges 7 and 8 provided on the indoor side and the outdoor side are respectively connected to the indoor side end and the outdoor side of the fixing member 6. Abutting on the end portion, screws 9 a and 9 b are screwed in from the indoor side and the outdoor side, respectively, and the mounting edges 7 and 8 and the fixing member 6 are fastened. In this case, since the dust between the vertical frame 2B of the sash and the opposing surface of the column is only about a few mm indicated by GB in FIG. 5, the sash cannot be easily inserted into the housing opening. Even if the size of the dust is small, the sash SB is unstable until it is fixed. Therefore, with the operator supporting the sash, the screw is screwed in the opposite direction on the indoor side and the outdoor side. Stopping work needs to be done. Therefore, it is difficult to ensure the dust on both the left and right sides before the fixing work, and there is a problem that the efficiency of sash mounting is poor.
[0006]
The present invention has been accomplished in view of the above problems, it can be easily ensured uniform dust on the left and right sides when the sash mounting, Ru can conduct the fixed sash high efficient The purpose is to provide a guide for taking out Chile .
[0007]
[Means for Solving the Problems]
To achieve the above Symbol purpose, dust out guide according to the present onset Ming, a leg which is bent in the same direction on both ends of the indoor and outdoor direction, the elastic pressing projecting in the opposite direction and its legs during its legs and a piece, the legs are engaged with the rear vertical frame of the sash, it is characterized in that mounted in a state of protruding to the pillar side of the elastic pressing pieces from the back of the vertical frame.
With the above configuration, the dust guide can be easily attached by sequentially elastically engaging the legs with the back surface of the vertical frame of the sash. When fitting the support Tsu sheet to skeleton openings dust out guide of the elastic pressing pieces can be easily be fitted in the elastic deformation, the finished fitted to a predetermined position, and restores the elastic pressing pieces, building frame Is pressed temporarily by frictional engagement. Therefore, since the sash can be permanently fixed in a stable state, the construction efficiency is improved.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Next, the form of the onset Ming embodiment with reference to FIGS. 1 to 3 of the accompanying drawings.
FIG. 1 is a transverse cross-sectional view corresponding to FIG. 5 when the housing is a steel frame, FIG. 2 is a development view of the dust guide, and FIG. 3 is an explanatory view of attaching the dust guide to the vertical frame.
[0009]
In FIG. 1, 1C is the right steel column which comprises a housing, and 2C is the right vertical frame of a sash SC. A dust guide 20 is attached to the vertical frame 2C on the back surface of the main wall 10, that is, on the side opposite to the center of the sash.
[0010]
Dust out guide 20, as shown in FIG. 2, made of a substantially rectangular leaf spring member, at both ends of the indoor and outdoor direction has legs 21 and 22 bent in the same direction, the legs 21, An elastic pressing piece 23 is provided between 22 and protrudes in the direction opposite to the leg . As will be described later, the elastic pressing piece 23 is fitted by sliding the sash SC inward of the housing opening along the opposing surfaces of the left and right columns, so that the sliding friction is reduced. It is bent or curved in a letter shape.
The distance between the legs 21 and 22 is substantially the same as the distance between the legs 11 and 12 protruding from the indoor side and the outdoor side at the back of the indoor side portion of the main wall 10 of the sash vertical frame 2C. Are equal. At least one of the legs 21 and 22 is formed with a plurality of claws 24 having a tip in a direction away from the tip of the leg on the surface opposite to the other. In the illustrated example, the claw 24 is provided on the indoor leg 21 of the dust guide 20.
[0011]
In this way, as shown in FIG. 3, the dust removal guide 20 first engages the outdoor leg 22 of the vertical frame 2C with the outdoor leg 22 having no claws, and then the indoor leg having the claws. 21 is pushed strongly toward the outdoor side surface of the leg 11 on the indoor side of the vertical frame, and the sharp tip of the claw 24 is inserted into the outdoor side surface of the indoor leg 11 by the elastic restoring force of the dust guide 20. Then, it is fixed to the vertical frame 2C by friction locking. And the elastic press piece 23 of the dust extraction guide 20 protrudes in the back side of a vertical frame in the attached state. A plurality of such dusting guides 20 are attached to the back surfaces of the left and right vertical frames at a uniform interval in the height direction of the vertical frame before the sash SC is attached.
[0012]
When the sash SC with the dust guide 20 attached in advance is attached to the housing, when the indoor portion of the sash is inserted into the housing opening 3 from the outdoor side, the elastic pressing piece 23 of the dust guide 20 faces the column 1C. While being in contact with the surface and being elastically deformed, it slides in the indoor direction along the opposing surface of the column. When the sash SC is inserted to a predetermined position where the mounting edge 13 of the vertical frame 2C comes into contact with the outdoor side surface of the column 1C, the sheet-like watertight member 32a that has been previously attached to the indoor side surface of the mounting edge 13 of the vertical frame 2C. Is closely attached to the outdoor side surface of the pillar 1C. When the mounting edge 13 abuts on the pillar 1C and further movement of the sash in the indoor direction is prevented, the left and right vertical frames of the sash are left and right by the restoring force of the elastic pressing piece 23 of the dust guide 20. Is held at a position spaced equidistant from GC. That is, the dust removal guide 20 secures a uniform dust GC between the left and right vertical frames and the left and right columns of the sash, and the sash SC is temporarily fixed to the housing.
[0013]
In this state where the sash is stabilized by temporary fixing, the inner peripheral frame 30a which is one constituent member of the frame 30 is preferably disposed between the vertical frame and the mounting edge 13 on the outdoor side of both vertical frames. The vertical frame 2C is fixed in earnest (main-fixation) by screwing the drilling bolt 31 that is interposed between the mounting edge 13 and the pillar 1C. Following this the permanent fixing, the outer peripheral frame 30b in the inner peripheral frame 30 a which is another component of the frame 30 in ledge form, i.e., there is formed on each of both end portions of the inner peripheral frame 30a and the outer peripheral frame 30b The frame 30 is completed by engaging the locking edges together. By making the frame into a two-divided configuration, the main fixing work by the drilling bolt 31 of the vertical frame 2C is facilitated, and the drilling bolt 31 after the main fixing is concealed to enhance crime prevention.
[0014]
Since FIG. 1 is an example in the case where the sash SC is a heat insulating sash, the vertical frame 2C connects the outdoor side metal frame member 2m and the indoor side resin frame member 2p by a known connection structure. The shoji D2 is also shown in a state where the outdoor side metal cage dm and the indoor side resin cage dp are joined together by a known connection structure. Regardless of whether it is a normal sash, the present invention can be similarly applied to a case where it is attached to either a wooden frame or a metal frame. Further, the sash SC may be any type of shoji open / close (drawing, pulling, double door), and may be a sash that fits.
[0015]
The dust guide 20 shown in the drawing is formed by bending both ends of a single leaf spring material in the same direction to form legs 21 and 22 , and cutting out a part of the central portion of the leaf spring material, thereby pressing the elastic pressing piece 23. This is a preferred embodiment because it can be easily manufactured and the manufacturing cost can be reduced as much as possible. However, in the present invention, the material, manufacturing method, shape and structure of the dust guide 20 are not limited to the above example. For example, the dust guide may be made of resin. The nail | claw 24 may provide the ditch | groove or convex part in the leg 21 of the indoor side, and may be made to latch on this. Further, as the elastic pressing piece, a structure in which a “H” shaped pressing plate or a spherical pressing body is fixed to the tip of the coil spring can be used.
[0016]
【The invention's effect】
As described above, according to this onset bright, it has an elastic pressing piece have a leg which is bent in the same direction on both ends of the indoor and outdoor direction and projecting in a direction opposite to the leg during its legs Therefore, by engaging the legs with the back surface of the vertical frame of the sash, a plurality of dust guides can be easily arranged at intervals in the vertical frame, and when the sash is fitted into the housing opening In addition, the sash can be stably and temporarily fixed to the casing by elastic deformation and restoration of the elastic pressing piece of the dust guide, and then the sash can be permanently fixed to the casing. That is, when attaching the sash, the sash can be easily inserted into the opening of the sash, uniform dust can be easily secured on both the left and right sides, and the sash can be fixed to the sash efficiently.
