Description

[Detailed Description of the Invention] Technical Field This invention relates to a support metal fitting used to attach a slat hanging box of a blind to a window frame or the like when a Venetian blind is installed on a window surface.

Prior art The support fitting for supporting the slat hanging box of a blind has a hanging member molded of synthetic resin etc. that can be inserted and fixed into an inverted L-shaped support frame, and the hanging member and the support frame can be used to hang the slat hanging box. The structure supported and fixed the structure.

However, such a support fitting has the disadvantage that when the support and fixation of the suspension box is released, the hanging member tends to fall off from the support frame, making the installation of the suspension box complicated.

Purpose The purpose of this invention is to eliminate the drawbacks of the conventional support metal fittings mentioned above and to provide a support metal fitting in which the hanging member does not fall off even when the support and fixation of the hanging box is released.

Embodiment Hereinafter, an embodiment embodying this invention will be described with reference to the drawings. In the drawing, 1 is a support frame formed into an approximately inverted L shape by a vertical portion 2 and a horizontal portion 3;
Several holes 4 are transparently provided for attachment to a window frame, etc., and reinforcing ribs 5 are extruded on the horizontal portion 3 and corner portions. Reference numerals 6 and 7 refer to supporting side plates for reinforcement in which the left and right edges of the vertical portion 2 and the horizontal portion 3 are respectively bent at right angles toward the box B side. A notch recess 8 is formed to which the upper edge f of one side of the box B can be engaged, and a locking recess 9 capable of engaging the upper edge e of the other side of the box B is curved upward at the lower end thereof. Further, on the lower side of the support side plate 7, a hanging member 1 (described later) is provided.
2 is bent at right angles, and a locking hole is provided near the tip of the same side plate 7 to prevent the locking member 12 from coming off. 11 is transparent.

Reference numeral 12 denotes a box hooking member made of synthetic resin that is inserted into the horizontal portion 3 of the support frame 1 from its tip side so as to be movable in the front and back direction, and the inner end thereof is provided with a notch in the support frame 1. A latching protrusion 13 capable of latching the upper edge f of the box B that has entered the recess 8 is integrally formed, and on both sides of the outer end, the box B latched to the latching recess 9 of the support frame 1 is attached. A pair of locking pieces 14 capable of locking the upper edge portion e from above are integrally formed via an arm 15. A protrusion 14a is formed on the lower surface of this locking piece 14 to restrict movement of the box in the front-rear direction, and a protrusion 14b is formed on the upper side to be locked to the tip edge 3a of the horizontal portion 3 of the support frame 1. has been done.

Reference numeral 16 denotes a locking tongue piece integrally formed with the locking member 12 so as to be located between the arms 15, for locking the locking member 12 in the locking position, and has a recessed portion on the lower side of its base end. 16a is formed so that the box can be tilted upward, and a locking protrusion 16b that is locked to the upper edge e of the box is integrally formed at the tip of the lower surface.

17 are recesses 1 provided on both left and right sides of the hanging member 12.
A pair of stopper pieces integrally formed within 8,
The distal ends thereof are formed to protrude obliquely so that the closer to the locking piece 14 the outer side is, and the end opposite to the insertion direction has a surface that extends inward from the protruding top and is substantially perpendicular to the insertion direction. is formed.

Next, the function of the supporting metal fitting for the blind hanging box constructed as described above will be explained.

When attaching a blind hanging box to a window frame, the support frame 1 is first fixed to the window frame or the like, and the hanging member 12 is inserted into the horizontal portion 3 of the support frame 1. Once the locking member 12 is inserted into the support frame 1 until the stopper piece 17 reaches the inner part (left side in FIG. 4) of the support frame 1 than the locking hole 11, the stopper piece 17 will be moved by the action of the slope. Passage over the inner surface of the support side plate 7 and the locking hole 11 is allowed. In FIG. 4, when the locking member 12 is moved to the right to be pulled out from the support frame 1, the stopper piece 17 is moved as shown in FIG.
Since the orthogonal surface on the opposite side to the insertion direction engages with the locking hole 11, the locking member 12 cannot be moved any further in the same direction.

To lock the box B, first, with the notch recess 8 open and the locking piece 14 and the locking protrusion 16b spaced apart from the locking recess 9, as shown in FIG. With the box B tilted, one upper edge e is hooked into the hooking recess 9, and the box B is rotated in the direction of the arrow in FIG. 8. Thereafter, when the latching member 12 is moved forward, the latching protrusion 16b of the latching tongue 16 comes into contact with the upper edge e of the box B, but the latching tongue 16 resists its own elasticity. Since it is rotated upward around the recess 16a,
The locking protrusion 16b is moved along the semicircular arc-shaped surface of the upper edge e. (See FIG. 5) When the protrusion 14b of the locking piece 14 comes into contact with the tip edge 3a of the horizontal portion 3 and the locking member 12 stops, the upper edge of one of the boxes B is closed as shown in FIG. The portion f is latched by the latching protrusion 13, the other upper edge e is latched by a pair of latching pieces 14, and the latching protrusion 16b is raised from the upper edge e. The locking member 12 is secured to the upper edge of the box B, so that the locking member 12 is securely held in the locking position of the box B. When unlatching the box B, the locking tongue piece 16 is tilted upward to release the lock between the locking protrusion 16b and the upper edge e of the box B, and the locking member 12 is moved outward. Just let it happen.

At this time, the stopper piece 17 of the locking member 12 engages with the locking hole 11 of the support frame 1 as described above. is held in
Therefore, the hooking member 12 will not fall off from the support frame 1 when the box B is attached or detached.

Effects As detailed above, this invention consists of a support frame 1 having a horizontal portion 3 attached to a window frame, etc., and a hook inserted from the tip of the horizontal portion 3 into the horizontal portion 3 by horizontal movement. In this support metal fitting, the hanging box B of the blind is held between the support frame 1 and the hanging member 12 in the horizontal part 3, and both sides of the horizontal part 3 are A locking hole 11 is provided in the supporting side plate 7 formed by bending it at right angles to the B side, and the locking member 12 is made of a flexible material, and the outer side is formed on both sides facing in the direction opposite to the insertion direction. A stopper piece 17 is provided that projects obliquely to the stopper piece 1.
By forming a surface substantially orthogonal to the insertion direction inward from the protruding top at the end opposite to the insertion direction of box B, and making the stopper piece 17 engageable with the locking hole 11, the box B can be locked. Even if the locking member 12 is moved to the position where it is released, the locking member 12 does not fall off from the support frame 1, so an excellent effect is achieved in which the box B can be easily attached and detached.
