Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a slat constituting a shutter curtain of a lightweight shutter, and more particularly to a slat of a window shutter.
[0002]
[Prior art]
In the case of window shutters consisting of slats that are externally attached to windows around the outer wall of the building and are bound in multiple stages by interlocks, when manually opening and closing the shutters, pull them down with your fingers on the handle that is fitted to the slats. Measures such as pulling up and operating by pressing a finger against the interlock portion of the slat have been taken.
[0003]
[Problems to be solved by the invention]
However, in such a conventional shutter, a hand slat has to be prepared separately in order to provide a so-called hand part. In addition, when the shutter is lowered by pulling the slat directly downward, the cross-sectional shape of the slat is linear or curved at the intermediate part other than the interlock part, so the part where the hand is applied is necessarily the interlock part or intermediate part. Since this part is limited to a part that shifts from the part to the interlock part, and only a part of the fingertip is applied to such a part, the burden on the fingertip is large. Furthermore, the seat plate can be directly gripped and raised or lowered, but it is necessary to rely on experience and intuition as to which part should be gripped. Also, as shown in FIG. 10, there are some which have a protruding side toward the middle in the height direction of the seat plate, but if you try to lower the shutter by putting your fingertip on the protruding side, the lower end of the seat plate will bend forward. In order to rub against the outdoor guide groove of the guide rail, more technique was required. Even in the case of an electric window shutter, operations similar to these must be performed during a power failure.
[0004]
The present invention has been made in view of such problems, and an object of the present invention is to provide a shutter that can be easily operated manually by using the components of the seat plate and the slat directly above.
[0005]
[Means for Solving the Problems]
As a means for this, the shutter according to the present invention is a shutter composed of slats arranged in multiple stages by an interlock, and the seat plate constituting the lowermost slat is associated with the lower interlock portion of the slat directly above the seat plate. while the upper interlocking unit for coupling the to form a horizontal projecting edge indoors direction from said indoor side upper portion located above the upper interlocking unit with formed, the intermediate portion of the immediately above slat tip portion indoor side A surface portion formed by the projecting portion and the horizontal projecting side so that the projecting projecting portion is formed, and the horizontal projecting side is positioned at substantially the same level as the indoor-side tip of the projecting portion. it is characterized in that it has a structure to secure the region worked by the. Moreover, in this thing, it is preferable that the upper surface of a protruding part has a horizontal surface part.
[0006]
[Action]
By doing so, in the present invention, (1) when the shutter is closed, the entire fingertip can be pressed firmly over both the protruding portion and the horizontal protruding side, so that the burden on the fingertip can be reduced. (2) Since the surface of both the protruding part and the horizontal protruding side can be used, the protruding dimension of the horizontal protruding side in the indoor direction is made as small as possible compared to pressing only the horizontal protruding side. can do. (3) Since the horizontal protruding side is located at the upper end of the seat plate, the lower frame of the sash does not obstruct the hand, and the shutter can be more easily closed. (4) It is not necessary to prepare different slats that have been processed by hand, and the handle parts can be omitted. (5) Pressing with the fingertip results in pressing the protruding portion in the hanging direction, so that the slat can be smoothly lowered with respect to the guide groove of the guide rail. (6) If the upper surface of the projecting portion is a horizontal surface, the above effects are further increased.

DETAILED DESCRIPTION OF THE INVENTION
1 to 4 show a first embodiment of the present invention. FIG. 1 is a sectional view showing a closed state of a shutter. FIG. 2 is a sectional view showing engagement between a seat plate and a slat directly above. FIG. 3 is a perspective view showing the engagement between the seat plate, the horizontal protruding side and the guide rail, and FIG. 4 is a longitudinal sectional view of the shutter.
[0008]
In FIG. 4, 1 is an outer wall of a building, 2 is a base material for attaching a sash frame, 3 is a sash frame that is attached to the outdoor side of the base material 2, and includes upper and lower frames 3a and 3b and left and right vertical frames 3c and 3c. It is enclosed and 3d is a shoji. A shutter case 4 provided above the sash frame 3 is fixed to the outer wall 1 of the building with nails (or bolts) 6. The shutter case 4 includes a front case 4a, an upper case 4b, lower cases 4c and 4d, and a side case 4e. Reference numeral 5 denotes a bearing bracket, and a winding drum 5b for winding the shutter is attached to the bearing 5a. The winding drum 5b is provided with a bullet machine that facilitates manual opening and closing (not shown).

Reference numeral 7 denotes a guide rail which is erected with the guide groove 7a facing the left and right vertical frames 3c and 3c of the sash frame 3. Denoted at 8 is a drainer provided at the lower end of the guide rail 7. The drainer 8 is composed of a saddle plate portion 8a that slopes in the outdoor direction, a tip drainer portion 8b, a fixed side 8c, and the like.
The drainer 8 is below the sash lower frame 3b, and the fixed side 8c is fixed to the outer wall 1 of the building with a nail or the like.
[0010]
Reference numeral 9 denotes a slat constituting a shutter curtain, and a lowermost slat 10 is a seat plate. Each slat 9 is composed of an upper interlock portion 9a, a lower interlock portion 9b, and an intermediate portion 9c for continuous binding. A portion 9d that continuously transitions from the intermediate portion 9c to the lower interlock portion 9b forms a protruding portion that faces the tip end portion 9e on the indoor side, and extends across the entire longitudinal direction of the slat 9 in the cross-sectional view. The front end portion 9e protrudes in the indoor direction. Generally, the cross-sectional shape of the slat 9 is such that the intermediate portion 9c is flat or slightly curved on the outdoor side. Since the continuous slats 9 are inserted and guided in the guide grooves 7a and 7a of the left and right guide rails 7 and 7 and are moved up and down, the thickness dimension X1 of the slats 9 is limited to the groove width dimension X2 of the guide groove 7a. As a result, the protruding dimension of the projecting portion 9d in the indoor direction is inevitably within the groove width dimension X2, which is only a part of the fingertip.
In the present embodiment, the protruding portion 9d is provided at the transition portion to the lower interlock portion 9b. However, the protruding portion 9d is not limited to this, and for example, a plurality of protruding portions 9d (not shown) are provided in the intermediate portion 9c. , 9d... May be provided. However, in this case, it is desirable to take an interval that allows the fingertip to enter between the protruding portions 9d and 9d.
[0011]
The seat plate 10 includes an interlock portion 10a that engages with the lower interlock portion 9b of the slat 9 directly above, an intermediate portion 10b, an indoor draining portion 10c, an outdoor draining portion 10d, a lock mounting portion 10e, and a horizontal protruding side. 10f.
The horizontal protruding side 10f is located above the upper interlock portion 10a, and the tip end portion 9e of the protruding portion 9d and the horizontal protruding side 10f are positioned at substantially the same level. As shown in FIG. 1, at least the dimension of the horizontal protruding side 10f protruding in the room can place a fingertip on the protruding portion 9d and the horizontal protruding side 10f, and does not contact the shoji 3a and the sash frame 3. If it is within the range, the specified dimensions are not required. Moreover, you may provide the standing side 10g which raised the indoor direction front-end | tip part of the horizontal protrusion side 10f slightly further. A resin stopper (not shown) is attached to the outdoor side of the intermediate portion 9b to prevent the shutter from being caught in the shutter case 4. In addition, the upper surface of the horizontal protruding side 10f can be made uneven to prevent slipping.
[0012]
When the shutter having the seat plate 10 configured as described above is manually closed, the shutter is opened as follows. First, a hand is put on the indoor drainer 10c or the horizontal protruding side 10f of the seat plate 10, and the seat plate 10 is pulled downward by sliding the guide groove 7a. Along with this, the directly above slats and the series of slats above the slats that are bound together with the seat plate 10 are also lowered at the same time. At a position where the seat plate 10 is lowered to some extent, the fingertip is pushed further down by pushing the protruding portion 9d and the horizontal protruding side 10f. Thus, since the horizontal protruding side 10f is located on the indoor side above the indoor drainer 10c and is also above the lower frame of the sash frame 3, the seat plate 10 can be easily pushed down to the wall surface 8a of the drainer 8. Can do. In this depressed state, the lock is automatically locked by a lock device (not shown) housed in the lock attachment portion 10e.
[0013]
When it is desired to open the shutter, it is sufficient to push up the horizontal protruding side 10f from below and perform an operation substantially opposite to the above-described closing method.
[0014]
FIG. 5 shows a second embodiment of the present invention and is a sectional view showing a closed state of the shutter. The present embodiment is different from the first embodiment in that the upper surface of the projecting portion 9d has a horizontal surface portion. This makes it easier for the fingertips to touch both sides of the protruding portion 9d and the horizontal protruding side 10f, making it easier to close the shutter.
[0015]
6 and 7 show a third embodiment of the present invention, and FIG. 6 is a sectional view showing a closed state of the shutter.
FIG. 7 is a perspective view showing the engagement between the seat plate 10, the horizontal protruding side 10 f and the guide rail 7.
In the present embodiment, the difference from the second embodiment is that the protruding dimension of the horizontal protruding side 10f to the indoor side is reduced to be within the groove width X2 of the guide groove 7a of the guide rail. Both ends in the direction can be directly inserted into the guide groove 7a without being cut out (FIG. 7).
[0016]
Even in this case, the same opening and closing of the shutter as in the first embodiment can be easily performed.
[0017]
8 and 9 show a fourth embodiment of the present invention, and FIG. 8 is a sectional view showing a closed state of the shutter. FIG. 9 is a perspective view showing the engagement between the seat plate 10, the horizontal protruding side 10 f and the guide rail 7.
In the present embodiment, the difference from the third embodiment is that the handle 12 is attached to the indoor end of the horizontal protruding side 10f with the same protruding dimension to the indoor side of the horizontal protruding side 10f. It is what I wore. The handle 12 can also be slid in the longitudinal direction of the seat plate 10 along the standing side 10g. Therefore, the dimension of the handle 12 in the longitudinal direction of the seat plate 10 is sufficient if the fingertip can be dimensioned. Of course, the dimension may be slightly shorter than between the left and right guide rails 7. Moreover, as shown in FIG. 9, the small handle 12 can be attached or slid to the part close to the guide rail. The handle 12 is made of resin or aluminum.
[0018]
In short, the present invention is to secure an area corresponding to a handle by the surface portion formed by the protruding portion 9d of the slat and the horizontal protruding side 10f of the seat plate 10, and the various actions unique to the present invention described above. An effect can be produced.
