The shutter or panel element is generally connected at each end to a mounting member that is pivotally mounted to the frame member. Typically, one or more adjustment rods connect the individual mounting members mounted on each frame so that the rotational movement of each shutter or panel element can be adjusted. Also, when the user moves the adjustment rod,
An operating handle is provided for adjusting the shutter or panel element between open and closed positions.

(Problem to be Solved by the Invention) However, since conventional armored windows are usually composed of a large number of independent parts, not only do all the parts have to be manufactured, but the assembly of the window requires There has been a problem in that labor costs, where time and labor account for most of the final cost of the product, have increased, leading to higher manufacturing costs. In addition to increased costs, there is also the problem of a lack of reliability due to the large number of parts, which can cause fasteners to loosen or become damaged due to corrosion or abrasion caused by operation.

It is therefore an object of the present invention to provide an adjustable armor window which has a simple and effective construction, which directly facilitates and is economical to manufacture.

(Means for Solving the Problems) As a means for solving the problems described above, the present invention provides a pair of frame members arranged opposite to each other in parallel, and two or more frame members disposed between the frame members. It consists of a panel or shutter element, and a mounting member attached to each end of the panel or shutter element, and the mounting member has a boss rotatably attached to a boss insertion hole provided in the frame member. and a locking means for substantially preventing movement of the boss in the axial direction within the boss insertion hole except when the mounting member is at a predetermined angular position with respect to the frame member, The angular position is a position that cannot be reached by the mounting member during normal opening and closing operations of the window, and the boss can be inserted into and removed from the boss insertion hole only at the predetermined angular position, and The boss of the mounted mounting member is rotatably connected by a pair of adjustment rods, the boss has a pair of cylindrical protrusions that are rotatably fitted into the fitting holes of the adjustment rods, and The adjustment rod is prevented from disengaging from the cylindrical projection by the positioning means;
The present invention provides an adjustable armor window characterized in that when the mounting member is at the predetermined angular position, it can be inserted into and removed from the cylindrical protrusion.

In a preferred embodiment of the invention, the locking means are formed by at least one radial projection integrated with the boss, which projection engages the frame member on the side opposite to that on which the mounting member is arranged. . A recess is formed in the peripheral edge of the boss-fitting hole so that the protrusion can pass through the boss-fitting hole when the mounting member is at the predetermined angular position. Therefore, by aligning the protrusion with the recess, the boss can be moved in the axial direction, and the protrusion can be inserted into and removed from the boss insertion hole. In a preferred embodiment, the boss has a circular cross-sectional shape and a pair of opposing radial protrusions, and the recess of the boss insertion hole has a size and shape corresponding to the radial protrusions. There is.

The pivoting movement of the mounting members is effected by adjustment rods that interconnect the individual mounting members mounted on each frame member. In a preferred embodiment,
Parallel adjustment rods are disposed within the frame member, each adjustment rod being rotatably connected to a cylindrical projection projecting from a boss of each mounting member. The pair of cylindrical protrusions provided on each boss are arranged on a line that intersects the axis of rotation of the boss, and at or near the angular position where the boss is allowed to move in the axial direction within the boss insertion hole. When there is a mounting member on the mounting member, the adjustment rods are arranged so that they are closest to each other.

The frame member is provided with fixing flanges as a positioning means for retaining the adjustment rod in the cylindrical projection during normal opening and closing operations of the window. The adjustment rod is formed so that it can be attached to or removed from the cylindrical protrusion.

Accordingly, the present invention provides an armored window in which the mounting member and adjustment rod can be attached to the frame member without the need for any separate fasteners.
The armored window can thus be constructed with a minimum number of components, facilitating and economical its manufacture and assembly.

The invention will now be described in detail with reference to the accompanying drawings, in which examples are shown.

Adjustable armored windows according to the invention can be equipped with one or more adjustable shutter or panel elements depending on the particular application of the window. The shutter or panel element 40 is of conventional construction, usually made of transparent or opaque glass. In FIG. 1, a mounting member 10 for a shutter or panel element is shown attached to a frame 11. As shown in FIG.

The frame 11 is typically of channel-shaped cross-section and may be constructed of any material, for example a metal alloy with a suitable corrosion-resistant coating, such as provided by anodizing or powder coating. A plurality of holes 13 are provided along the entire length of the base flange 12 of the frame 11 for passing fasteners for attaching the frame 11 to a window surround (see FIG. 4). These holes 13 are
The window is arranged so as to be covered by the mounting member 10 when the window is closed.

As shown in FIG. 1, the side flanges 14 of the frame 11 are each formed with a flange 15 projecting inward at its free end. This flange 15 allows the frame 11 to be attached to either a wooden window frame or a metal window frame. Thus, the frame 11 can be attached to the front, back, or front of the window frame depending on the type, shape, and profile of the particular window frame.

Mounting member 10 is preferably formed from a plastic material such as a resilient synthetic resin with a low coefficient of friction. Accordingly, the mounting member 10 can be integrally molded, is easy to manufacture, and provides the mounting member with a pleasing and aesthetically pleasing appearance. Mounting member 10
has a groove 16 that opens into a tongue-and-groove portion 17 at both ends. This allows the shutter or panel element 40 to be pushed directly into the groove 16 or slid into the groove from its open end. The tongue and groove 17 allow the shutter or panel elements to overlap when the armored window is in the closed position.

The groove 16 is defined by a pair of parallel flanges 18 projecting upwardly from the base 19 of the mounting member 10. The lowermost end of flange 18 curves downwardly and outwardly to join base 19 to form an edge 20 which, in use, moves frame 11 as mounting member 10 moves about its axis.
act as a wiper blade or wiper edge that comes into contact with the surface and wipes moisture from the surface.

Projecting downwardly from the base 19 of the mounting member 10 is a circular boss 21, preferably of slightly larger diameter than the spacing between the edges 20. The diameter of this circular boss 21 is the diameter of the base flange 12 of the frame 11.
The diameter of the boss insertion hole 22 is substantially the same as that of the circular boss 2, or is slightly smaller.
1 can be inserted into the boss insertion hole 22 and can be rotated there.

The locking means is formed by a pair of protrusions 23, which are provided at symmetrical positions at the ends of the boss 21. In order to enable the boss 21 to be inserted into the boss fitting hole 22 together with its protrusion 23, a recess 24 having a size and shape corresponding to the protrusion 23 is formed in the boss fitting hole 22 (FIG. 4). . Projection 23
By aligning the boss 21 with the recess 24
can be inserted into the boss insertion hole 22, and then by rotating the mounting member 10, the boss 21 can be inserted into the base flange 1 as shown in FIG.
Movement in the axial direction within the boss insertion hole 22 is substantially restrained by the protrusion 23 that engages with the lower side of the boss 2 . Therefore, the attachment member 10 to the frame 11
The boss 21 can only be moved to the frame 11 at a specific angular position.
The mounting member 10 can be moved axially relative to the mounting member 10.
can be removed from the frame 11.

A pair of cylindrical projections 25 are provided at the free end of the boss 21.
The cylindrical protrusion 25 has a circular cross-sectional shape and is arranged symmetrically with respect to the rotation axis of the boss 21, as shown in FIG. The cylindrical protrusions 25 are provided on each side of a diametrically elongated extension 26 whose ends form the protrusion 23 .

The adjustment rod 27 has an L-shaped cross section and has a plurality of holes along the entire length of one flange into which the cylindrical protrusion 25 is inserted. Other flange 2
7a extends parallel to the side flanges 14 of the frame 11. Note that a fixed flange 28 is provided on each side flange 14 of the frame 11.

When the mounting member 10 is rotated around the rotation axis of the boss 21, the adjustment rod 27 moves laterally, and the mounting member 1
0 is at an angle with respect to the frame 11 as shown in FIG. 1, the positions are closest to each other. This angular state is preferably set in the boss insertion hole 2.
This is the position of the mounting member 10 when the boss 21 is allowed to move in the axial direction within the mounting member 2. As is clear from FIG. 1, the end of the flange 27a is connected to the adjustment rod 2.
When 7 is in this position, it leaves the terminal edge of the respective fixing flange 28. Therefore, in this position, the adjustment rod 27 can be removed from the cylindrical protrusion 25 and the boss 21 can be pulled out from the boss insertion hole 22. However, this position of the mounting member 10 relative to the frame 11 is such that the mounting member 10 cannot be moved during normal opening and closing operations of the armored window. Therefore, during normal opening and closing operations, the adjustment rod 27 slidably abuts the fixed flange 28 and the cylindrical protrusion 25
The terminal edge of the flange 27a is located at the rear of the fixed flange 28 so that it cannot be separated from the fixed flange 28.

The lateral movement of the adjustment rod 27 within the frame 11 is controlled by the operation handle 30 (sixth
(see figure). The operation handle 30 is approximately L-shaped, and has a handle portion 31 located outside the frame 11.
and a handle base 32 disposed through and within a groove in the side flange 14 of the frame 11. The adjustment rod 27 is pivotably connected to the base 32 of the operating handle 30 at a pivot point 34 and to the arm 36 at a pivot point 35, and the other end of the arm 36 is pivotably coupled to the handle base 32 at a pivot point 33. There is. FIG. 6 shows in solid lines the position that the operating handle 30 assumes when the armor window is completely closed and the adjustment rod 27 is in the position shown. In this figure, the state of the arm 36 when the operating handle 30 is inserted into the groove of the side flange 14 is shown by broken lines.

When the operating handle 30 is rotated in the direction indicated by the arrow, first, the pivot point 33 connecting the arm 36 and the handle base 32 is slightly displaced in the same direction, and then the pivot points 34 and 35 move around the pivot point 33. ,
This causes the adjustment rod 27 to move and open the window. As can be seen from Figure 6, when the window is closed, the turning point 3
It is locked by the overcenter effect imparted by the misalignment of 3, 34, and 35.

As described above, the armored window according to the present invention is composed of a plurality of shutters or panel elements, a mounting member 10, two frames 11, an adjustment rod 27, and an operating lever 30. By employing the structure detailed above, the boss 21 of the mounting member 10
The mounting member 10 can be completely attached to the frame member by inserting the adjustment rod 27 into each boss insertion hole 22 and then attaching the adjustment rod 27 to the cylindrical protrusion 25. They do not need to be fixed to each other. In addition to the interaction of the protrusion 23 with the inner surface of the base flange 12 of the frame 11, the terminal edge of the flange 27a of the adjustment rod 27, which is located behind the fixed flange 28, ensures that the mounting member remains closed during normal opening and closing operations of the window. 10 and adjustment rod 2
7 never comes off. Therefore, this armored window has a minimal number of parts and no fasteners, allowing the end user to assemble the window before attaching it to the window frame. It is particularly suitable for sale in the form of a complete set of assembled parts.

One of the great advantages of the armored window according to the invention is that the panel element mounting groove 16 of the mounting member 10 has a width that corresponds to the minimum wall thickness of conventional glass. The wall thickness of such glass is usually
Flange 1 which is 4mm and forms a mounting groove
Due to the elasticity of 8, even 5-6 mm glass can be inserted. Additionally, the flexible edges 20 of the mounting member 10 provide a seal between the mounting member 10 and the frame 11, and the degree of sealing is such that when a thicker glass is inserted, the glass flange 18
is deformed or bent to bring the edge 20 and the surface of the base flange 12 into closer contact, so that it can be effectively increased.

The seal between the mounting member 10 and the frame 11 can be enhanced by contouring the surface of the base flange 12 in the form shown in FIGS. 4 and 5. The surface of the base flange 12 has a raised portion 3 extending from approximately around the hole 13 towards the flange 14 which is placed inside the window in use.
7 is provided. This raised portion 37 is 37a
As shown, it extends to the front part of the boss insertion hole 22 and surrounds it. Therefore, even if moisture passes through the seal formed by the surface of the mounting member 10 and the edge 20, it will face the ridges 37, 37a, and these ridges will act as a barrier to prevent moisture from entering the building. Prevented. Raised portion 37,3
The moisture accumulated at 7a is wiped away by the edge 20 the next time the window is opened. Therefore, the armored window structure according to the present invention has a completely opposite relationship to the conventional armored window structure. That is, in the conventional armored window structure, the seal is made on the outside surface of the window, so if water passes through the sealing part, it can directly enter the building, but in the armored window structure according to the present invention, the sealing part is sealed. All of the moisture that has passed through is blocked by the raised portions 37, 37a, and is prevented from entering the interior, as described above, and is removed when the window is opened.

In the embodiment described above, one recess 24 having a size and shape corresponding to the protrusion 23 is formed around the boss insertion hole 22, but a pair of recesses corresponding to the size and shape of the protrusion 23 is formed. It may also be provided.

(Effects of the Invention) As is clear from the above description, the armored window according to the present invention has a simple and economical structure, and uses a fastener to maintain the operational relationship between the mounting member and the adjustment rod. It can be easily assembled without any hassle. Further, the number of parts required for assembling the window can be far reduced compared to known armored window structures, and other excellent effects can be obtained.
