Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a balance weight attached to the lower end of a slat of a vertical blind.

[Conventional technology]

Conventionally, as a type of vertical blind balance weight, a lower end of a slat formed of cloth or the like is wound around a weight formed of a metal plate or the like, and the weight is housed in a case and suspended and supported at the lower end of the slat. Or a case in which a case accommodating a weight can be opened and closed and a claw for sandwiching a slat is provided on its inner surface, and the lower end of the slat is sandwiched by the case to suspend and support the weight on the lower end of the slat, etc. There is.

[Problems to be solved by the device]

In such a vertical blind, to adjust the total length of each slat, that is, the length including the balance weight of each slat hanging from the head box, adjust the length of the slat to be stored in the case of the balance weight. Done by. Therefore, in the case of a balance weight of the type in which the lower end of the slat is wound around the weight, when re-adjusting the total length of the slat at the installation site of the vertical blind, the slat wound around the plate-shaped weight is rewound to obtain the optimum length. It is necessary to wrap the slats around the weight, and this work is extremely complicated.

In addition, even with a balance weight of the type in which the lower end of the slat is sandwiched in the case, it is necessary to readjust the length of the slats to be stored and sandwiched in the case and re-sandwich, and when the slats are too long. Had to cut the lower end of the slat, and the work was complicated.

An object of the present invention is to provide a balance weight for a vertical blind in which the readjustment work of the entire slat length is easy.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the balance weight, which is supported by the lower end of the slat of the vertical blind and is tensioned by the slats, guides the slat into the case and fixes the lower end of the slat into the case. The slat is bent in the middle of reaching the lower end of the slat to form a center-folded portion, and the weight plate attached to the case is provided with a plurality of hanging means. The length of the center folding part can be adjusted by selectively hanging the folding part, and the center folding part hooked on the hanging means is hooked with the lower end of the slat fixed to the case. It is removable from the means.

[Action]

By the above means, the length of the center-folded portion is adjusted by selecting an appropriate hanging means from the plurality of hanging means provided on the weight plate attached to the case and hanging the middle-folded portion. , It becomes possible to readjust the slat length.

Particularly, in the present invention, by adjusting the vertical position of the slat bending portion to adjust the slat length, the position adjustment amount of the slat bending portion does not directly affect the slat length, but the slat length. Since the length of the fold of the slat is approximately twice as long as the length of the slat affects the total length of the slat, a slight adjustment of the slat bend greatly adjusts the total length of the slat. As a result, the balance weight (case) can be made compact.

Further, in the present invention, since the lower end portion of the slat can be removed from the hanging means while being fixed to the case, the total length of the slat can be readjusted very easily.

〔Example〕

Hereinafter, a first embodiment embodying the present invention will be described with reference to FIGS.
Referring to FIG. 3, the balance weight 1 has a lid 3 formed on one side of the case 2, and the lid 3 has an upper edge rotatably connected to an upper edge of the case 2 to open and close one side of the case 2. Has become. As shown in FIG. 2, the upper edge of the lid 3 is connected to the case 2 by the connecting portions 4 only on both sides thereof, and the slats 6 are inserted through the slits 5 provided between the connecting portions 4 into the case 2. To be done.

A first weight plate 7 formed of a metal plate is rotatably supported by a shaft 8 in the upper part of the case 2, and the lower end of the first weight plate 7 is folded back upward. Further, a plurality of locking pieces 9 that are punched out by a press and project toward the center are formed on both sides of the front surface of the first weight plate 7 at equal intervals in the vertical direction.

A second weight plate 10 is rotatably supported by a shaft 11 at the lower part of the case 2, and can be housed in front of the first weight plate 7 in the case 2 as shown in FIG. There is. It should be noted that stoppers (not shown) that engage with the lower edge of the case 2 are formed on both sides of the lower edge of the lid 3, and the stoppers engage with each other when the lid 3 is closed as shown in FIG. 3 is kept in that state.

Now, in order to attach the balance weight 1 configured as described above to the lower edge of the slat 6, the lid 3 is opened and the first and second weight plates 7 and 10 are moved forward as shown in FIG. The slat 6 is inserted into the case 2 through the slit 5 at the upper edge of the case 2 while being rotated. Then, the slat 6 is guided from the back surface of the first weight plate 7 to the front surface through the lower edge thereof, and after forming the center folded portion 12 at that position, the slat 6 is transferred to the front surface through the lower edge of the second weight plate 10. The slat 6 is bonded and fixed to the upper part of the back surface of the second weight plate 10 through the upper edge of the second weight plate 10 with the double-sided tape 13.

Next, the slats 6 above the case 2 are appropriately drawn into the case 2 to adjust the length of the center-folded portion 12, and both sides of the upper edge of the slats 6 are attached to one of the locking pieces 9 on both sides of the first weight plate 7. The first and second weight plates 7 and 10 are housed in the case 2 in this state as shown in FIG. 3 and the slats 6 on the upper part of the case 2 are pulled upward, as shown in FIG. When the slack of 6 is removed and the lid 3 is closed in that state, the balance weight 1 is suspended and supported below the slats 6.

In addition, when it is necessary to readjust the total length of the slats 6 that suspend and support the balance weight 1 at the installation site of this vertical blind, adjust the length of the center folding part 12 in the case 2. By doing so, the total length of the slat can be easily corrected. That is, when the overall length of the slat 6 is too long, the slat 6 is pulled into the case 2 to increase the length of the center-folded portion 12, and the slat 6 is hooked to the upper locking piece 9. On the other hand, when the overall length of the slat 6 is too short, the slat 6 is pulled out of the case 2 so that the length of the center-folded portion 12 is shortened, and the upper edge of the center-folded portion 12 is lowered to a lower locking piece 9.
The readjustment work is completed when the lid 3 is closed after being hung on.

As described above, in the balance weight 1, in order to readjust the entire length of the slat 6, the length of the center folding portion 12 may be adjusted while the lower end of the slat 6 is fixed to the second weight plate 10. Therefore, the lower end of the slat 6 is attached to the second weight plate.
You can easily correct the slat length by adjusting the length of the middle fold 12 without removing it from 10.
The length of the center-folded portion 12 can be easily adjusted with the first weight plate 7 rotated to the outside of the case 2.

Next, a second embodiment embodying the present invention will be described with reference to FIG. 4 and FIG. 5 only in the portion different from the first embodiment. The same components as those in the above embodiment will be described with the same reference numerals.

As shown in FIG. 4, a large number of fitting claws 14 projecting forward are formed on both sides of the first weight plate 7, and the hooks having an oval cross section are attached to the first weight plate 7. Fitting holes 16 into which fitting claws 14 are detachably fitted are formed in both ends of the stop bar 15. The fitting claw 14 and the latch bar 1
A mounting means is constituted by 5 and the fitting hole 16. Then, in place of the locking piece 9 of the above-described embodiment, the center-folded portion 12 of the slat 6 is mounted on the latch bar 15, and when the length of the center-folded portion 12 is adjusted, the latch bar 15 is fitted. By appropriately changing the position, it is possible to obtain the same effect as that of the first embodiment.

In this embodiment, since the slats 6 are mounted on the round retaining bar 15 on the entire surface of the slats 6, the case 2
Pull the upper slats 6 upward to pull the slats 6 inside the case 2.
When straining the slat 6 as in the first embodiment.
There is an advantage that the slat 6 is less likely to be scratched, as compared with the case where both sides are hooked on the locking piece 9.

In addition, as shown in FIG. 6, the slats 6 inserted into the case 2 from the slits 5 first form the center-folded portion 12, and then the rear surface of the first weight plate 7 is moved around the slats 6 in the case 2. It may be arranged such that it is guided to the front surface of the second weight plate 10 via the lower edges of the first and second weight plates 7 and 10 and fixed to the upper part of the second weight plate 10 by the double-sided tape 13.

Further, in both the first and second embodiments, the upper edge of the case 2 is used as a hinge and the lower edge of the case 2 is opened, but the same may be applied to the case where the upper edge is opened.

[Effect of device]

As described in detail above, in the present invention, the readjustment of the total length of the slat can be easily performed by adjusting the length of the center-folded portion in the case while the lower end of the slat is fixed to the case. With respect to the length of the center-folded portion, if the slat bending portion is slightly adjusted, the overall length of the slat can be greatly adjusted, and as a result, the balance weight can be made compact.
