Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an up / down window provided with a descent braking mechanism.

[0002]

2. Description of the Related Art Up-and-down windows provide a tall window and are suitable for ventilation windows. This window may also be used as a smoke exhaust window.

[0003]

However, in the case of this smoke exhaust window, for example, when the outside is used as a crossing corridor, if the upper shoji falls suddenly, the limb of a person passing through the crossing corridor is sandwiched. There is a risk that it will.

Accordingly, a main object of the present invention is to prevent the upper sash from falling suddenly in this kind of case and the like.
An object of the present invention is to provide a safety window.

[0005]

According to a first aspect of the present invention, there is provided an invention in which an upper sash is vertically movable and a lower sash is fixed to a raising / lowering window. It is an up-and-down window characterized by being provided.

According to a second aspect of the present invention, moving pulleys are attached to the upper frame of the upper shoji at intervals in the direction of the find in the up-and-down windows in which the upper shoji is movable up and down and the lower shoji is fixed. Attach fixed pulleys in the window upper frame at intervals in the finding direction at both sides of the line,
One end of the wires sequentially wound around these pulleys is fixed to a fixed portion, and the upper sash is moved up and down by winding and feeding the other end, and the wires are fed to one end of the wires. A lifting mechanism provided with a braking mechanism for braking the vehicle.

According to a third aspect of the present invention, there is provided an up-and-down window in which an upper sash and a lower sash are provided in a window frame in a continuous window state, each upper sash is movable up and down, and each lower sash is fixed. Moving pulleys are attached to the upper frame at intervals in the finding direction, and fixed pulleys are installed in the window frame as a pair of moving pulleys at both sides of the vertical line of each moving pulley at intervals in the finding direction. Wires are sequentially wound around each pair of pulleys of the upper sash, then wires are sequentially wound around each pair of pulleys of the adjacent upper sash, one end of the wires is fixed to the fixed portion, and the other end is wound. An up-and-down window characterized in that each upper sash is moved up and down in common by extension and a braking mechanism for braking extension of the wires is provided at one end of the wires.

The "braking mechanism" of the present invention refers to a mechanism or means for lowering the lowering speed of the upper sash as compared with the lowering speed when the braking mechanism is not provided. .

[0009]

Embodiments of the present invention will be described below in more detail with reference to the drawings. As shown in FIGS. 1 to 3, in the window of the embodiment, upper sash screens 1 </ b> A to 1 </ b> A
1D and lower shoji 2A to 2D are provided in a continuous window state,
Each of the upper sashes 1A to 1D is vertically movable and each of the lower sashes 2A to
An up / down window to which 2D is fixed is configured.

The moving pulleys 30, 30 are attached to the upper frame 10 of each of the upper sash screens 1A to 1D at intervals in the finding direction by screws or the like via a support 30A holding the moving pulleys, and the moving pulleys 30, 30 are respectively mounted. The fixed pulleys 31, 31 and 31, 31 as a set of the two movable pulleys 30, 30 are spaced apart in the finding direction at both side positions of the vertical line of the vehicle through the support 31A which holds the fixed pulleys 31, 31 in the window upper frame 20. It is attached with screws.

As shown in FIGS. 4 and 5, guide rollers 40 are mounted on both lower sides of the vertical frame 11 of each of the upper sash screens 1A to 1D, so that the vertical movement along the vertical frame 21 is facilitated. Is being planned.

Referring also to FIGS. 6 and subsequent drawings, a smoke exhaust vertical operation unit 50 is provided at an appropriate position at the end of the window, for example, on a nearby upright wall. The smoke evacuation upper / lower operation unit 50 winds and unwinds the wire 51. When an operation button 50a is pressed in an emergency, the two wires 51 and 51 are simultaneously unwound and rotate the handle 50b or 50b. And wires 51 or 51 individually
Is to wind up. The wires 51, 51 are inserted into a flexible conduit 51A.

The wire 51 rises along the wall and enters the window upper frame 20 at a position corresponding to the end of the upper shoji 1A, as shown in FIGS. The group of 1B is raised and lowered. The other wire 51 enters the window upper frame 20 at a position corresponding to the end of the upper sash (shoji) 1C, so as to raise and lower the set of the upper sash (shoji) 1C and 1D.

A wire 51 is sequentially wound around each set of the upper shoji 1A pulleys, and subsequently, a wire 51 is sequentially wound around each set of the pulleys of the adjacent upper shoji 1B, and one end of the wire 51 is fixed to a fixed portion, a window frame or the like. It is fixed to the frame. Another wire 51 is similarly wound around the set of upper sashes 1C and 1D.

However, when the upper sash (shoji) 1A to 1D suddenly descends, there is a risk that a limb of a person passing through the crossing corridor may be pinched. Therefore, for example, the smoke evacuation operation unit 50
A braking mechanism (for example, “Stay damper”, not shown) manufactured by OILES CORPORATION is provided therein. As this braking mechanism, a known mechanism such as a so-called piston type or rotary type can be used.

Thus, even when the smoke is exhausted, the upper shoji 1A
Since １1D descends slowly, it is released from the risk of pinching the limb of a passing person.

As shown in FIGS. 4 and 5, a stopper 61 made of rubber or the like is fixed to the lower end of the upper sash. Further, stoppers 62 are fixed to the upper ends of the lower sashes 2A to 2D so as to protrude toward the upper sashes 1A to 1D, thereby defining an ascending limit.

[0018]

As described above, according to the present invention, it is possible to prevent the upper sash from falling suddenly and to obtain a highly safe up / down window.
