Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for use in panel enclosures such as office partitions, smO partitions, display cases, furniture, etc.
Vehicles, ships or navigation using s)! Structures such as Shin et al.
Concerning windows, glazing, screens and panel surrounds used in residential, commercial and industrial structures and products.

Many elements such as rivets, screws, nuts, bolts, elastomers and bead sealants are used for the manufacture of window panes and shielding assemblies, for their incorporation into structures of the aforementioned type. Currently in use.

Many systems used will not provide effective arboreal action because the components are not sealed together sufficiently. On the other hand, if the positive sealing measures are carried out by using multiple frame elements joined using fasteners, the labor and material costs are high.

With the advent of regulations governing the use of glass putty in railroad vehicles to meet certain impact and bullet resistance standards, most currently used glass glazing for door windows, side windows, and windshields has been It turns out that the frame Sa cannot be used.

Additionally, if currently used railroad vehicles must be retrofitted to comply with these regulations, many of the constraints in the vehicle structure preclude the use of commonly used window structures.

Vandalism, especially to rolling stock and railroad cars, is a very costly problem. In this regard, exposed fasteners that can be easily retracted and easily removable elastic materials (e.g. used in putty work on subway car door windows) are susceptible to malicious destruction. It has little resistance to humans.

Conventionally known window sills for single panes and fixed structures include several common types. Place 11 “depression” or “
In the case of the "protruding" type, the window frame is fitted into the opening, and the bolts pass through the 7 lunges on the outer periphery of the window frame and penetrate into the side and wall of the house.
It is held in place using fasteners such as screws, rivets, etc. In the case of a "retainer" type construction, the window frame is held in place in the wall opening using a separate retaining element that is secured by a four-pronged fastener. In the case of "tightening ring" type,
There is another continuous window frame attached to the 111 side of the structure on the opposite side of the window frame, and these two parts are secured together by fasteners so as to engage the walls of the structure by a binding action. be done. In another common configuration, an element is typically inserted into the cavity of the main gas get to provide a tension and capture force to hold the window frame in place on the wall of the structure. This includes the use of gas foot strips of elastic material, which are strips that emerge from two sections.

All installations known in the art have costs g and 4
The complexity of 111Jt is considerable, and the service life is
It has considerable disadvantages in terms of resistance to damage and vandalism, and ease of conversion.

The present invention relates to a new and improved system for the installation of in-place panels in windows, which can be used at a lower cost than comparable companies compared to previously known techniques, and which offers superior performance customization. It is something that General K. The sealing system of the present invention utilizes a deformable aluminum continuous-form extruded window frame section with a sealing panel and/or putty without the need for substantially other components. Alternatively, it is possible to attach the structure of the window frame to the wall surface without putty. The structure of the present invention is first formed to be disposed at a large angle to the pressure point, and finally forms a pair of channels that are not channel shaped. This window frame portion is cut into a closed shape, and the four parts of the window frame are joined by bath welding or the like. Next, the sealing panel (g
A lazing panel) can be fitted into a window frame, one of the flanges, referred to herein as a roll-over flange, being pressed into the edge of the panel by hand or machine. Not only is it quick and efficient, but the resulting panel fixation is far superior to #1 most conventional installation methods.

For this purpose, a sealing strip of elastic material is generally inserted between the sealing panel and the window frame, which sealing strip is secured by a 73 flange forming a channel around the entire circumference of the panel. When gripped, it provides a very infantile seal.

! In a complete installation, both the attachment of the sealing panel to the window frame and the attachment of the putty window frame to the structural wall are performed by roll-over seven-lunges. The use of this roll-over 7-lunge in the 1st dimension of the window frame to the structural wall provides maximum flexibility in the design of the window frame section for wall construction and/or replacement work. It is very advantageous in that it enables sex.

Due to the airtight and complete gripping action between the window frame and the sealing panel,
The sealing system of the present invention has excellent resistance to the impact of large objects, such as the United States Transportation Agency's safety transportation standard FMV88.
It exceeds the requirements of No. 217 by an amount of light. At the same time, the high pressure resistance of the sealing panels and/or structural walls makes the system much more resistant to vandalism than previously known systems. .

In addition to its exceptional performance customization, the sealing system of the present invention provides significant advantages over previously known systems on the grounds of cost and ease of operation. Because it does not require drilling and the use of separate fixings, installation of sealing panels according to the invention takes three-quarters of the time required in prior art systems, which are acceptable for example in rail car and subway type sealing devices. Implemented with - or ten minutes of -1
It is Ding Noh.

Installation of sealing panels and the like according to the present invention can be easily carried out by unskilled workers using relatively crude tools such as hammers and chisels.

For a fuller understanding of the above g and other features and advantages of the present invention, please consult the following detailed description and drawings of preferred embodiments of the present invention. In particular, the term "sealing" as used in the text does not limit this to glass or plastic panels, but applies to the installation of all types of panels for all end-use applications as previously mentioned in the text. should be understood to be used in its broadest sense, including

Next, in the drawings, initially in FIGS. 1 and 2, reference number 10 generally indicates a basic support structure such as a building, a vehicle body, etc. This structure is typically made from extruded aluminum, such as, but not limited to, aluminum alloy 6063T4, which fits into the closed window frame for the desired application purpose. 11, and the ends are welded or otherwise joined to form a closed shape.

As shown in FIG. 2, the window frame 11 typically includes a main body defining a bottom seat 13 for a glazing or other type of panel structure 14. 12
has. Sturdy 7 lunges 1 forming a ridge channel
5 extends from said body 12 and typically provides edge support for the piece 11 of the sealing panel 14, although not necessarily the inner edge. Wall thickness is approximately 12.7■ (1/2 inch f)
In a typical configuration intended for panel installation, the side support 7 langes 15 are approximately 3.81 own (a, 1s
It has a base wall thickness of 4 degrees and a total thickness of approximately 3/4 inch. From the opposite side of the barrel 5120, its initial position or state is shown by the dotted line in FIG.
Extending is the $2 channel-forming 7 flange 16 whose installed state is shown by a solid line. In the initial position of the 7-lunge 16, sometimes referred to as a roll-over 7-rank, the 7-lunge 16 is attached to a sealed or other panel 1.
approximately 900 mm relative to the opposite 7 flange 15 so that the 7 flange 160 can be inserted directly into the fully closed window frame portion 11 from the open side defined by the 7 flange 160 dotted line position. It extends with a corner.

The effective buffering and sealing action of the sealing panel 14 (s+ea
ling), the edge g17 of this panel is initially @g
It is cushioned by elastic material in the form of strips 18, 19 and edge cushioning strips 20. These strips 18-20 may be adhesive-backed neoprene or other plastic strips that are inserted into the threshold between the panel material and the aluminum window frame to allow the sealing panel 14 and /Or it is adhered to the inner surface of the window frame portion 11. Alternatively, a single piece of material with a U-shaped cross section can be used. The use of this elastic material is, of course, particularly important if the encapsulation material is glass or other fragile material. This is important primarily because it provides a very effective wind and weather resistant seal between the sealing panel 14 and the window frame 11.

According to the present invention, the window frame portion 11 in which the most vJKi1 portion opens
After installation of the sealing panel 14, the first open side flange element 16 is rolled or otherwise folded against the edge of the sealing panel into the position shown in solid lines in FIG. At this point, elastic cushioning materials 18 to 2
0 indicates that the roll-over side 7 flange 16 is pressed into contact with the sealing panel 140 to produce a firm continuous positive grip, thus providing a highly effective weatherproof seal. enable.

As reflected in Figure 2, rollover,
The base or root of the 72 inch 16 is provided along its inner edge with a recess 21 which is approximately semicircular in the initial or open configuration m of the 72 inch. This recess provides a definition line that facilitates the formation of a 7Kunji 160 deft and precise fold. Similarly, this recess closes slightly during the rollover step to prevent the formation of metal transformations in the area of the corner bends.

However, it is not important that the roll-over 7-lunge be bent only along the O-line of the recess. In the typical case, the bends and folds of this roll-over 7-lunge are at a transition pace, although they are generally more concentrated along the line of this recess.
l basis).

In the embodiment of the invention shown in FIG. 2, the window frame portion 11 has a second trough-forming roll-over 7-piece 22 initially oriented substantially perpendicular to the main mounting flange 23. It is provided. This attachment 7 lange 23 is integral with the body 12 and extends therefrom. In the illustrated configuration, the attachment 7 langes 23 are generally parallel to the plane of the sealing panel 14, although the completed panel assembly may have an excessive shape and orientation relative to the structure to which it is attached. .

As will be appreciated, during installation of the sealing panel, the structural wall 24 is designed to correspond to the size and shape of the finished round window frame 110 so that the assembled sealing window frame can be easily inserted into the opening in the panel. An opening having a size and shape is provided. 7 runs of deformable installation! >22 is WI2
It extends into the opening indicated by reference numeral 25 in the figure and projects at least partially beyond the surface 26 opposite the wax surface of the structure. In the illustrated configuration, the mounting flange 25 is a structural part! Disposed facing the outer surface of the rotor 24, the deformable mounting 7 flange 22 extends beyond the inner surface 26. The elastic sealing material 27 is attached to the structural wall surface 24
and the window frame portion 11. This may be in the form of a U-shaped cross-section or a number of suitable force strips.

After inserting the window frame into the opening 25 of the structure, the deformable roll-over 7 langes 22 are engaged and the structure wall l1
It is deformed outward (downward in FIG. 2) relative to the inner edge of lr24. This deformable attachment 7 lange 22 is
One or more approximately semi-cylindrical recesses s2B are provided along the surface facing the structure (bottom tl in Figure 182),
This defines fold lines to centrally enable folding and bending of the material in the desired manner. Advantageously, the deformable mounting 7 flange 22 is provided with a tongue 29 along its outer edge for engaging a tool to facilitate mounting.

In a typical case, the sealing panel 14 can be attached to the window frame g11 as a factory operation, in which case a suitable press or other tool is used to perform the roll-over operation of the seven lunges 16 that engage the panel. power plant can be used.

Installation of the sealing window frame in the structure is also typically a field operation, in which case a portable movable implement or hand tool is used in the rollover operation of the deformable mounting 7 flange 22.

Assembly of the sealing panel 14 and field assembly of the assembly are greatly simplified by the construction of the present invention. The sealing panel is assembled and the window frame is attached to the structure without the use of bolts, rivets, bullets or other aids. Significant savings are therefore realized in the use and assembly of new structures for the attachment of sealing panels and other panels.

In the embodiment of FIGS. 1 and 2, there are seven lunges 16.
．． 7 langes 22 are provided for both the attachment of sealing panels and other panels and the attachment of equipment to structural walls 24. In the embodiments of FIGS. 3 to 6, a roll-over, seven-lunge device is provided for attaching window frames to structural walls, and is further used for attaching sealing panels and other panels. General facilities provided.

Although the apparatus of Figures 3 to 7 lacks drying robustness in terms of resistance to vandalism and impact forces, it can be used to attach sealing panels and other panels without damaging window frames on structural walls. It enables the exchange of

FIG. 4S shows a partial view similar to FIG. 2 showing an assembled window frame attached to a structural wall.

The window frame portion 50 made of aluminum by extrusion molding etc. has a base g.
31 and from which extends a t-jernel-forming 7 flange 52, the base and the inner surface of the 7 flange being arranged at a generally right angle. Structure I1 surface-engaging 7 langes 33 extend from the base 31 generally opposite said channel-forming 7 langes 32 and include deformable flanges 3 that cooperatively engage the wall surface.
It is related to 4.

The sealing panel or other panel is first attached to the window frame g30 by sealing the main channel form to the flange 32 using a suitable resilient sealing material. The elastic then connects the sket strip 36 to the channel forming 7 flange 32.
It is pushed into a recess 35 located in the base 31 spaced apart from the base 31 . A resilient gasket 36 resiliently abuts the edges of the sealing panel 370 to securely hold it to the assembled window frame. The hawking of the window frame to the structural wall 38 is carried out in the same manner as described with respect to the embodiment of FIG. This window frame is a modified OTD 7 lunge 3
4 is inserted into the opening 69 in the structure wall until it protrudes beyond the inner surface of the wall. For example, as shown at 4o, an elastic tape or the like is attached to the main support 7 flange 36 and the structural wall surface 3.
It is inserted between 8 and 8. This elastic material also has openings 39
This may be in the form of a U-shaped gasket used against the edge of a structural wall in .

When the window frame is held in place on the structural wall, the seven langes 34 are deformed outwardly toward the structural wall 38 into a tight-fitting relationship, thereby connecting the window frame 30 and the structural wall. 38 to provide a strong weather-resistant seal.

By way of example only, in the typical commercially available apparatus shown in FIGS. Aluminum alloy 606ST4 cut to size
It can be formed from materials such as. The wall thickness is about 12.
For 7 mm (1/2 inch) sealing panels and other panels Kh, channel forming 7 langes 52 that engage the panel.
It has a length g of about 1905 Wm (3/4 int) and a base wall thickness of about 581 mm (α15 inf).

Roll-over 7 langes 34i; i have a typical effective length of about 12.7 cm (1/2 inch) depending on the wall thickness of the structure and about 1ρQ 5 mg (075 inches) of wall thickness. It has a thickness. Roughly semi-cylindrical relief channels 41,42 are provided on the lower Ufj (outer surface) of the deformable 7 flange 34, these channels typically having a length of approximately α79 m
(α051 inches). The use of multiple relief channels is generally desirable because it allows the preformed window frame to better fit within the dimensional tolerances of the opening in the structure surface. For example, in the case of a relatively large opening, the seven rungs 54 may partially bend in the first relief channel 41 and bend further into the second relief channel 42, so that the seven rungs can easily attach to the structure wall. reach it.

The gas get receiving recess 35 typically has a diameter of about 5.842 mm.
The width of 11111 (0,230 ind) and about 991 fights (α
It has a depth of about 39 inches f). This recess is preferably provided with a plurality of "serrated" projections 45 that allow insertion of the resilient gasket 36 but resist its removal from the recess.

The exemplary materials used in the extrusion of the window frames of FIGS. 1-6 are highly malleable and can therefore be subjected to significant strain without cracking or tearing. Therefore, the malleability of the material is sufficient to allow the necessary shaping, provided that the window frame does not bend around fairly sharp corner radii. Thus, for example, about 5α8o■
For sections with the above typical dimensions for shapes that yield small corner radii (2 inches), the window frame installation should be medium 7 inches.
It is desirable to provide a notch in the roll-over 7-lunge 34 in the area of the corner in order to minimize the problem of cornering in the roll-over operation of the lunge. A suitable cut configuration is shown in FIG. 6, where symmetrical cuts 44 are formed in the corners, leaving a center tab 48 of complete 7-rank material. Notch 44.45 typically has a length of about 2 inches and a spacing of about 18 inches, for example, and tab 46 has a length of about 1 inch. It has a certain length.

These dimensions S and shape of the ore, shape of the corner, degree of seed, and q of the material
#Gender etc. 4? roll over 7 according to the specified details.
There is a lot of experience with requirements regarding the cut depth of the corners of the lunges, so it is not very important.

The window frame section shown in the WIZ drawings is particularly as used in connection with window sealing systems of the type that constitute the subject matter of our copending U.S. patent application Ser. No. 179,770, which is incorporated herein by reference. be. The cross-sectional view of Figure f$7 includes first and second channel-forming 7 flanges 50.51 arranged substantially at right angles to the phase ff1K.

As in the previous embodiment, the window frame section, generally designated 52, is made of a continuous length of aluminum, of the type illustrated, formed in a closed configuration to form a window frame. It is an extruded bottom type material. This window frame is the structure wall surface 540
The structure wall yB54 is firmly gripped so that the 7-lunge 51, which is arranged to be inserted into the opening 53 and then called the roll-over 7-lunge, is in a channel-forming relationship parallel to the channel-forming 7-lunge 50. Folded outwards to form a relationship. Preferably, a corresponding elastic gasket strip or channel 55 is provided between this flanges 50,51 and the structural wall surface 54, at least on the outer surface of the wall surface.

As shown in FIG. 7, the channel forming seventh run 51 is provided with a bending defining recess 57 along its inner channel forming II surface 56. Approximately 1905m (α075 in f
) for flanges with typical total wall thickness, concave G5
7 may have a substantially semi-cylindrical cross section with a radius of approximately α787 m (α031 inf). Both conditions help locate the axis of the bend and allow for the transformation of the material that occurs as a result of the bending operation. However, concave t! l657
It is not absolutely necessary that the bend be made exactly along an axis or line defined by. However, the recess 57
The location of is preferably predetermined relative to the intended wall thickness of the structural housing wall 54 so that roll-over bending is at least substantially concentrated in and thereby permitted in the FIII recess.

After positioning of the window frame and rolling over of the channel forming 7 flange 51 for permanent attachment in the structural wall 54, a separate fit is made in the recess defined by the outwardly extending flange 58. A window frame with putty is inserted. In accordance with the principles outlined in our pending U.S. patent application, a spring-like 7.
The lunge passes through the recess 6 by the tongue 59 protruding inwardly.
0 to snap into place for permanent attachment.

The window frame section of FIG. 8 is designed for screen attachment for a fusible panel, most typically a window or door. Window frame sa, generally indicated by the number 70, in conjunction with other components 73, 74, first and second channel formations 7
Includes lunge 71.72. In a typical configuration, this window frame WB70 is mitered with nine corners (mit
It is assembled into a ring-shaped window frame with a sred corner). The first t-channel-shaped 7 flange 71 is placed substantially in the plane of the soufrille panel 75, whereas the channel-forming 7 flange 72 of Alternative 2 is initially placed at a substantial angle to the 7 flange of WIll. has been done. The entire window frame is a continuous extrusion of aluminum that is cut to size and assembled into a regular square window frame.

As shown in Figure 8, I! is called the roll over 7 lunge. The base 76 of the channel-forming 7 flange 72 of the second channel-forming 72 flange is rounded and entirely recessed in thickness to allow for subsequent closure of the channel-forming 7 flange during the roll-over operation. integrally joined to the rest.

The pre-cut portions of the screen 75 to form the screen panel are placed on the assembled window frame section at the top of the first channel forming 7 langes 71. Near the base of the channel forming flange 71, there is a roll over
7 Serrations on lunge (serrF on) 78
A series of serrations 77 are provided which are associated with fishing and fishing. These serrations extend continuously in the longitudinal direction of the window frame section and form alternating sharp protrusions and recesses.

The precut screen 75 is of sufficient size that its edges overlap the serrated projections 77. Therefore, when the channel-forming 7 flange 72 is closed against the channel-forming 7 flange 71, the edges of this screen are firmly gripped by the serrated projections 77, 78, and these projections As is clear, the protrusions on one side are placed in the 4 on the other side.

Advantageously, the inner edge of the first Dejanel-forming 7 flange 71 is provided with a relatively deep smooth recess 79, which recess extends along the inner side of the channel-forming 7 flange 72 with a spherical head 80 of the same shape. is arranged synergistically in relation to. The geometry of the channel-forming seven runs 1771 and 72 is such that during the roll-over operation of the channel-forming flange 72, the edge-grasping serrations 77 and 78 initially contact and grip the screen; This is fixed in place. After that, the spherical head 8
0 begins to enter the recess 79 in the 7 lunge and 8 on the opposite side,
Displace the screen material into this recess. This state is
It has the effect of tensioning the screen around its periphery, providing an attractive installation with a clean finish.

Since the channel forming 7 flange 72 is not intended for reuse, it is desirable that the window frame g70 is provided with a circumferential recess t481 along its inner edge.

If the window frame screen needs to be replaced, the edges of the new screen are inserted into the recesses 81, followed by the insertion of elastic splines (not shown), in accordance with well known conventional methods. This can be done by doing this.

The construction of the present invention, in any of its various forms, enables the installation of windows and other panels to vehicles and fixed structures to be carried out with significant performance and economic advantages over conventional constructions. It is something to do. One of the further advantageous end uses of the invention is in connection with people carrying vehicles (locomotives, passenger cars, crew dLs), many of which withstand the impact of small and large objects. Must be modified to meet government regulations regarding competency.

The structure according to the invention provides a new and improved sealing assembly with minimal cornering effort and expense, yet with very high performance standards in terms of impact, anti-vandalism, effective sealing, etc. This makes assembly a breeze.

The gist of the present invention is the provision of a roll-over 7-lunge in an extruded aluminum sealing window frame, which can be used to improve the placement of the sealing panel within the window frame and/or the rollover of the window frame. Completion of assembly by placement within an opening in a structural wall and folding of flanges forming a channel allows for the formation of a tight, permanent seal without the need for drilling, use of separate fixtures, etc. It is something. Assembly can be carried out within a minimum amount of time, by relatively unskilled labor, and using the simplest types of tools.

The window frame itself has a very simple structure and is a relatively simple form of aluminum extrusion, which can be cut to the appropriate length for the opening in the wall of the structure to be accommodated. , can be folded into the required closed configuration.

It is to be understood that the particular forms of the invention shown and described herein are susceptible to many modifications without departing from the clear teachings of this disclosure and are intended to be illustrative only. Reference should therefore be made to the appended claims, which define the full scope of the invention.
