Abstract

PROBLEM TO BE SOLVED: To strengthen and simplify the installation of a lock holding member by forming projections on the rear side of a mounting seat of the lock holding member interlocked with a latch of a casement window, and making the projections enter a window frame to fix. SOLUTION: Pointed projections 62 are formed on the rear side of a flat section (mounting seat) 50 of a lock holding member 14, and when they are fixed to window frame 14, etc., with bolts 58, the projections 62 are made to enter the window frame, etc. When they are interlocked with a latch 16 of a casement window 12 and in the case force in the direction of the arrow acts on them, the force can be accepted by clamping force of the bolts 58 and frictional force of the entering projections 62. In that case, the projections 62 are formed of a hard member, and when the frame body 24 is formed of a member with less hardness of surface such as wood, aluminium, the projections 62 can be simply entered into the frame body. By the constitution, the lock holding member 14 can be simply and strongly fixed without enlarging each of the bolts 58 or increasing the number of bolts.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a lock receiving member,
More particularly, the present invention relates to a lock receiving member that engages with a latch of a casement window to lock the casement window.

[0002]

2. Description of the Related Art A conventional lock receiving member is fixed to a frame supporting a casement window through a fastening member such as a screw or a rivet. By the way, since the casement window provided on the outer wall of the building is required to be airtight and watertight, the lock receiving member and the latch can press the casement window against the frame when the casement window is locked. It is a mechanism that can do it. For this reason, the lock receiving member can increase the size of the fastening member because the reaction force from the opening window is transmitted through the latch.
We are taking countermeasures by increasing the quantity.

[0003]

However, in the conventional lock receiving member, it is necessary to increase the size of the fastening member or increase the number of the fastening members. There is a disadvantage that. The present invention has been made in view of such circumstances, and has as its object to provide a lock receiving member that can be easily and firmly fixed.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is provided on a frame to which a casement window is attached,
In the lock receiving member to be engaged with the latch of the casement window, the lock receiving member is formed at its corner with a protrusion that can bite into the frame, and the lock receiving member is attached to the frame by a fastening member. Thereby, the protrusion of the lock receiving member is cut into the frame and fixed.

According to the present invention, when the lock receiving member is fixed to the frame by the fastening member, the projection of the lock receiving member bites into the frame. Therefore, according to the present invention, the lock receiving member can be fixed only by fastening with the fastening member. Further, according to the present invention, since the projection is cut into the frame, the lock receiving member can be firmly fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a lock receiving member according to the present invention will be described below in detail with reference to the accompanying drawings.
FIG. 1 is an assembled perspective view of a sash to which a lock receiving member according to an embodiment of the present invention is applied. As shown in the figure, the sash includes an outer frame 10, a casement window 12, a lock receiving member 14 (see FIG. 2),
And a latch 16 (see FIGS. 1 and 2).

The outer frame 10 is formed into a rectangular frame by an upper frame 18, a lower frame 20, a right frame 22, and a left frame 24.
A rectangular space 2 for attaching the casement window 12 to the inside.
6 are formed. Also, as shown in FIG.
Are adhered along the inner wall surface of the outer frame 10. Casement window 1
2 is closed, the packing 28 comes into contact with the inner peripheral edge portion 12A of the opening window 12, and when the latch 16 is engaged with the lock receiving member 14, the opening window 12 is pulled toward the outer frame 10 and the inner peripheral edge 12A. The portion 12A is closely attached to the packing 28.

In FIG. 1, the sliding door 12 has an upper frame 30, a lower frame 32, and a pair of left and right vertical frames 34, 36. A transparent glass plate 38 is fitted and fixed in the sliding frame. The casement window 12 is attached to the outer frame 10 via upper and lower friction arms 40 so as to be openable and closable. One support plate 42 of the friction arm 40 is screwed with screws 44, 44,.
And the other support plate 46 is provided with screws 48, 48
Are attached to the upper frame 18 and the lower frame 20 of the outer frame 10.

FIG. 2 is a sectional view of a main part showing a state where the latch 16 is engaged with the lock receiving member 14, and FIG.
4 is a cross-sectional view taken along line 4-4 in FIG. As shown in FIGS. 2 to 4, the lock receiving member 14 includes a flat portion 50 and a bent portion 52. The flat portion 50 is formed in a substantially horseshoe shape, and long holes 56, 56 are formed in the branch portions 54, 54 shown in FIG. In FIG.
The bolt 58 shown in FIG.
It is fastened to the screw hole 60 formed in the left frame 24 shown by the two-dot chain line. Thereby, the lock receiving member 14 is fixed to the left frame 24. In addition, the lock receiving member 14 extends along the long hole 56.
Is slid, the lock receiving member 14 can be positioned at a desired position.

By the way, sharp projections 62 are formed on the branch portions 54 of the flat portion 50. This projection 62
Is formed at the corner of the branch portion 54,
It is formed facing the mounting surface with the left frame 24. Therefore, when the lock receiving member 14 is fixed by the bolt 58, the protrusions 62, 62. in this case,
If the protrusions 62 are formed of a hard member such as iron, and the left frame 24 is formed of a member having a low surface hardness such as wood or aluminum, the protrusions 62 can be easily bitten.

The bent portion 52 of the lock receiving member 14 has a tapered surface 64 and a straight surface 66 as shown in FIG. When the latch 16 is located on the straight surface 66, the lock receiving member 14 and the latch 16 are engaged. FIG.
In the above, the latch 16 is formed in a rod shape,
8 are arranged in a hole 68 formed. The base end of the latch 16 is fixed to the shaft 70. The shaft 70 is provided in a direction orthogonal to the latch 16 and is rotatably supported by the vertical frame 38. Also, shaft 7
A lever 74 is provided at the end of the room 0 on the side of the room 72. This lever 74 is manually operated.
When the lever 74 is turned to the horizontal position indicated by the two-dot chain line in FIG. 2, the latch 16 is retracted from the lock receiving member 14, and the opening window 12 is unlocked. When the lever 74 is turned to the vertical position indicated by the solid chain line in FIG. 2, the latch 16 is engaged with the straight surface 66 of the lock receiving member 14, so that the opening window 12 is locked. At this time, the casement window 12 is drawn toward the outer frame 10, and the inner peripheral portion 12 </ b> A is brought into close contact with the packing 28.

Next, the lock receiving member 1 constructed as described above is used.
The operation of No. 4 will be described. When the lock receiving member 14 is fixed to the outer frame 10 via the bolt 58, the lock receiving member 14
Are fixed with four protrusions 62, 62,... Biting into the left frame 24 of the outer frame 10. In this lock receiving member 14,
At the time of engagement with the latch 16, a reaction force (a force in the direction indicated by the arrow A in FIG. 2) is transmitted from the opening window 12, and the reaction force is received by a fastening force by the bolt 58 and a frictional force of a bite by the projection 62.

Therefore, the lock receiving member 1 of the present embodiment
In No. 4, since the projections 62 are fixed in the outer frame 10, the bolts 58 can be easily and firmly fixed without increasing the size or increasing the number of bolts 58.

[0014]

As described above, according to the lock receiving member of the present invention, a projection is formed on the lock receiving member, and the projection is cut into the mounting surface of the frame to fix the lock receiving member. As a result, it can be easily and firmly fixed.
