Description

[Detailed Description of the Invention] The present invention relates to a pull for use in a sliding window frame made of a hollow material such as an extruded aluminum profile or a synthetic resin material.

A pull used for a conventional sliding window frame will be explained based on FIGS. 7 and 8.

That is, a window frame made of a hollow material such as an extruded aluminum member or a synthetic resin material is shown, and the window frame 1 has an upper frame 2 and a door frame 3.
, a lower stile 4 and a lower stile 5.

This door frame 3 has a projecting piece 7 in the front vertical direction as a handle.

Although such a conventional handle provided integrally with the door frame 3 is inexpensive, it is not satisfactory in terms of appearance.

The object of the present invention is to provide a handle for a sliding window frame that has an excellent appearance and is easy to install.

FIG. 1 shows the handle A of the present invention installed in the hole 9 of the window frame 1.

Details are shown in FIGS. 2 to 4.

That is, the handle A of the present invention has a handle main body 10 having a handle recess 13 on the front and a pair of spring posts 14.14 spaced apart from each other by a predetermined distance in the vertical direction on the back, and is attached to each of the spring posts 14.14. It has a tabular spring 15 and a back plate 18 provided on the back side of the pull body 10 and to which a U-shaped spring 22 is fixed.

The pull main body 10 has a surface frame portion 11 that slightly protrudes toward the front (height i) between an outer peripheral edge 12 and the handle recess 13 on the front.

Each spring post 14 of the pull body 10 also has a pair of cut surfaces 16.degree. 16 (one on the opposite side, not shown) at symmetrical positions in the middle, as shown in FIG.

That is, the distance a between the shaved surfaces 16 and 16 is
is made shorter than the diameter d of.

Next, the back plate 18 provided on the back side of the pull main body 10 will be explained with reference to FIG. 5.

The back plate 18 is a plate-shaped body with a length approximately equal to the longitudinal length of the pull main body 10, and includes a central bottom portion 20 and wing portions 19 and 19 that continue upward in different steps at both longitudinal ends of the bottom portion 20. ,
It consists of a foot portion 21 bent below the end of each wing portion 19.

A U-shaped spring 22 is fixed at its bottom surface to the top surface of the bottom portion 20 by a fixing means such as welding.

Also, the side pieces 23.23 of the U-shaped spring 22 have their tips connected to the pull body 10.
The side pieces 23.23, which are oriented in the opposite direction, have at their tips an outwardly bent edge 23'.

Each wing portion 19 has a round hole 24 with a diameter d' in the middle and an elongated hole 25 with a width a' continuing from the round hole 24 in one direction (to the right in FIG. 5).
and has.

The diameter d' of the round hole 24 is slightly larger than the diameter d of the spring support 14, and the width a' of the elongated hole 25 is larger than the distance a between the cut surfaces 16, 16 of the spring support 14 and smaller than the diameter d. .

Since the length m of the foot portion 21 is approximately equal to the height difference n between the bottom portion 20 and the wing portion 19, the lower end of the foot portion 21 and the bottom portion 20 are approximately on the same plane.

The distance S between the bent edges 23', 23' in the free state is narrower than the width t of the back side of the pull main body 10.

Also, the height l of the side piece 23 is the depth j of the door frame 3 and the handle body 10.
The difference between the height k and the height k is the same as or slightly smaller.

Returning to FIG. 4, the back plate 18 is attached to the spring posts 14, 14 of the pull body 10 through its round holes 24,24.

Further, a spring 15 is attached to each spring support 14 between the back plate 18 and the pull main body 10.

The puller A of the present invention shown in FIGS. 2 to 6 having the above configuration
The method of attaching the window frame 1 to the window frame 1 will be explained below.

First, referring to FIG. 4, the back plate 18 is pressed toward the front against the spring 15.15 so that each round hole 24 coincides with the cut surface 16.16 of the spring post 14.

In this state, the back plate 18 is moved in a direction (downward in FIG. 4) so that the elongated hole 25 fits into the cut surface 16.16.

Here, since the width a' of the elongated hole 25 is larger than the distance a between the cut surfaces 16.16 and smaller than the diameter d, the force in the back direction acting from the spring 15 is applied to the cut surfaces 16.16.
The back plate 18 cannot be pulled out in the rear direction because it is received by the holder.

On the other hand, when the back plate 18 is pressed against the spring 15.15 toward the pull body 10, the distance between the side pieces 23.23 is enlarged and they come into contact with the sides of the pull body 10.

As a result of the above operations, the back plate 18 is positioned at the position shown in FIG. 4U, and the distance between the front of the pull main body 10 and the back surface of the back plate 18 is reduced.

In this state, insert the handle A into the door frame 3 through the opening at the upper or lower end of the door frame 3, and insert the surface frame 1 into the hole 9 of the door frame 3.
Insert 1.

Thereafter, the back plate 18 is moved upward from the position shown in FIG. 4U (FIG. 4) so that each round hole 24 is aligned with the cut surface 16.16.

As a result, the back plate 18 is released from the restraint of the shaved surface 16.16 and is pushed toward the back surface by the force of the spring 15.15.

As a result, the back surface of the back plate 18 is pressed against the inner surface of the door frame 3, and the edge 12 of the pull main body 10 is also pressed against the inner surface of the door frame 3 at the periphery of the hole 9 due to the reaction force.

Here, the height 1 of the side pieces 23 and 23 is the same as or slightly smaller than the difference between the depth j of the door frame 3 and the height k of the pull body 10, and the distance S between these tips is equal to or slightly smaller than the difference between the depth j of the door frame 3 and the height k of the pull body 10. 10, the side pieces 23, 23 are separated from the side surface of the pull body 10 and elastically enter the back surface of the main body 10, resulting in the state shown in FIG.

Here, the protruding height i of the front frame portion 11 is made approximately equal to the wall thickness of the door frame 3, so that the front surface of the front frame portion 11 is approximately flush with the front surface of the door frame 3.

The installation is now complete, and the handle A is held still in the door frame 3 by the elasticity of the springs 15, 15, and even when the handle body 10 is pushed, the side pieces 23 and 23 hit the back of the body 10, so the body 10 does not sink inward.

In the embodiments described above, the side pieces 23 have a bent edge 23' that bends outward at the tip, and this allows the operation of pressing the back plate 18 in the front direction to be performed smoothly.

Therefore, by enlarging the distance between the side pieces 23, 23 and pressing the back plate 18 in the front direction, the bent edge 23' may be omitted without causing any functional problems.

Further, the shaved surfaces 16, 16 of the spring support 14 and the elongated hole 25 of the back plate 18 are holding means for facilitating the operation of inserting the handle A into the door frame 3.

Therefore, if the back plate 18 is brought close to the pull main body 10 by manual operation when inserted into the door frame 3, the handle A can be removed even if the holding means is removed.
It is possible to install.

The handle of the present invention having the above configuration and attachment method has the following effects.

(1) The sliding window frame pull of the present invention has the structure described in the utility model registration claims, and in particular has a back plate 18 pressed by springs 15 and 15 on the back of the pull main body 10, so that the pull Spring 15.15 opens hole 9 in door frame 3.
It is extremely easy to install.

(2) The pull of the sliding window frame of the present invention has the same configuration as above, and in particular, since the U-shaped spring 22 is fixed to the back plate 18, when the pull is attached to the door frame 3, the U-shaped The side pieces 23.23 of the spring 22 are located on the back side of the pull body 10,
There is no need to worry about the tie puller sinking into the door frame 3.
