Description

[Detailed Description of the Invention] This invention relates to a sash crescent, and more particularly, to a sash crescent with an improved base.

Crescents are widely used for locking sash window frames because they have a simple structure and are easy to operate.

This crescent is locked by turning its cap and engaging the cap with the crescent holder.Usually, the crescent is locked and unlocked several times as the window frame is opened and closed, so the service life of the crescent is limited. is actually shorter than the Satsushi window frame.

For this reason, the crescent is often replaced before the satsushi is replaced.

Further, the crescent may break down due to the action of unexpected external forces, and in this case, it is cheaper to replace the crescent with a new one than to repair the crescent.

One of the problems faced when replacing the resent is that the pitch of the screw holes for fixing the crescent drilled in the existing sash window frame does not match the holes in the base of the new resent. It is necessary to separately drill screw holes in the sash window frame that match the holes in the crescent pedestal using a screwdriver, which makes the crescent replacement work cumbersome.

This is because the pitch of the holes in the crescent pedestal differs depending on the manufacturer or year of manufacture of the crescent.

Another problem is that even if the holes in the crescent pedestal and the screw holes in the sash window frame match, the crescent shade and the crescent holder do not fit together smoothly, and the engagement is caused by a large clearance and play. Otherwise, the engagement may be difficult and require a large amount of force, or the fixing portion of the crescent holder may be damaged.

This is due to dimensional changes between the shade and crescent holder due to the adaptation of the sash window frame to the house over time after construction material, or dimensional differences between manufacturers.

This idea was developed focusing on the points mentioned above.
To provide a crescent for a sash that can always fit into a screw hole drilled in a sash window frame and can be smoothly fitted with a crescent holder.

An embodiment of this invention will be described with reference to the accompanying drawings.

A female threaded hole 3 is provided in the pedestal 2 of the crescent 1 for sash.

A sleeve 5 having an elongated hole 4 and having an external thread is screwed into this hole 3 .

This rotation of the sleeve 5 relative to the base 2 allows the long hole 4 of the sleeve 5 to be inserted into the screw hole of the sash window frame.

Therefore, regardless of the pitch of the screw holes already drilled in the sash window frame, the long holes 4 and the screw holes can be easily matched by changing the position of the long holes 4 as the sleeve 5 rotates.

In addition, in order to obtain a smooth connection between the cap 6 and the crescent holder,
When the height of the hat needs to be adjusted, the sleeve 5 is rotated so that its lower end extends beyond the base to increase the height of the crescent 1 (see FIG. 3).

This extension of the sleeve 5 from the pedestal 2 results in an increase in the thickness of the pedestal 2 of the crescent 1, so that the desired engagement between the shade 6 and the crescent holder can be easily achieved.

Also, when it is necessary to adjust both the height of the crescent 1 and the alignment between the elongated hole 4 of the sleeve 5 and the screw hole of the sash window frame, rotate the sleeve 5 to obtain the required height. If the sleeve 5 is further rotated within 180 degrees (angle) at that position, the elongated hole 4 and the screw hole of the sash window frame can be easily aligned.

Further, when the height of the crescent and the elongated hole of the sleeve and the screw hole of the sash window frame need to be finely adjusted, the crescent 1 shown in FIG. 4 is effective.

In the example shown in FIG. 4, the sleeve 5 is screwed onto the inner wall of a cylindrical body 8, and this cylindrical body 8 is screwed into the screw hole 3 of the base 2.

In this example, the cylindrical body 8 is rotated to extend its lower end from the pedestal 2, and after obtaining the height of the crescent necessary for smooth engagement between the cap 6 and the crescent holder, this height is Without changing the sleeve 5, rotate the sleeve 5 so that the long hole 4 and the screw hole of the sash window frame match.

In this example, the adjustment between the height of the crescent and the position of the slotted hole is
Since each can be performed separately and independently, fine adjustment is possible.

The extension of the sleeve 5 or the cylindrical body 8 from the base 2 creates a gap between the bottom wall 7 of the base 2 and the lower surface of the sleeve 5 or the cylindrical body 8.

In order to hide this gap, it is advisable to attach a hook 9 to the pedestal 2.

The frame 9 has an outer wall 10 along the side wall of the pedestal 2 and a bottom wall 11, and the bottom wall 11 has a hole 12 around it, through which a screw is inserted through the elongated hole 4 into the screw hole of the sash window frame. The sleeve 5 extends from the pedestal 2 at the same time as the armature 9.
is shifted from pedestal 2.

Thus, the gap between the bottom wall 7 of the pedestal 2 and the lower end of the sleeve 5 is hidden by the hook 9, and the crescent 1 can be attached to the sash window frame without spoiling its appearance.

As is clear from the above, the rotation of the sleeve relative to the base makes it easy to adjust the height of the crescent and match the elongated hole of the sleeve with the sash window frame. Regardless, the crescent can be installed and safely locked on the existing sash window frame.
