DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 to 5, reference numeral 1 denotes a wooden frame opposed to a side end of a door 2, and is provided at a predetermined position on the end surface thereof. A vertically long rectangular concave hole 3 is formed, and a synthetic resin trowel 4 is accommodated in the hole 3.

The troyoke 4 is formed in a substantially box shape, and the bottomed latch receiving hole 5 is divided into left and right sides by side walls 6, 7.
One of the side walls 6 that engages with a latch described later is formed to be thicker than the other side wall 7, and a notch groove 9 is formed in the center of the front end face of the side wall 6, leaving a retaining wall 8. ing.

Protruding pieces 10, 10 project from upper and lower sides of the opening edge of the latch housing hole 5, and elongated holes 11, 11 are formed in the left-right direction of the protruding piece 10. A metal latch seat 12 is arranged on the overhanging pieces 10 and 10 in an overlapping manner. The seat 12 is formed in a vertically long rectangular plate shape wider than the troyoke 4, and has a vertically elongated shape on its front surface. The rectangular projection 13 is press-formed, and the trowel 4 is arranged inside the projection 13 so as to be movable in the left-right direction.

The projection height Z of the projection 13 is formed substantially the same as the thickness of the overhanging piece 10, and the vertical width Y of the projection 13 is formed substantially the same as the vertical width of the toyoke 4 and its width X. Is formed to be wider than the lateral width of the overhanging piece 10, that is, the lateral width of the trowel 4.
The upper and lower end surfaces of 0 and 10 are slidably arranged.

A vertically long rectangular opening window 14 is formed in the center of the convex portion 13, and a latch 15 provided at the side end of the door 2 so as to be able to protrude and retract can be inserted into the window 14. On one side of the opening edge of the opening window 14, a latching piece 16 is protruded inward, and the latching piece 16 can be engaged with the cutout groove 9 and can be engaged with the latching wall 8. The movement position of the troyoke 4 can be regulated.

In the drawing, reference numeral 17 denotes a screw hole formed at a position above and below the convex portion 13 so that a mounting screw 18 such as a wood screw can be inserted thereinto, and a burring portion 19 is provided at an inner opening edge thereof. The opening edge of the elongated hole 11 can be engaged with the portion 19. In addition, reference numeral 20 in the drawing denotes a latch seat 12.
This is a latch guide whose one end is gently curved, and is arranged to be engageable with the latch 15.

[0013] The latch receiver thus constructed is composed of the trowel 4 and the latch seat 12, and the latch seat 12 only needs to be slightly modified from the existing one, and the troyoke 4 is similar to that of the embodiment. If it is made of synthetic resin, the processing cost and material cost can be reduced as compared with conventional metal products, and it can be manufactured at low cost.

Next, when attaching the latch receiving member to the frame 1, the concave hole 3 having substantially the same shape as the trocar 4 is provided at a predetermined position of the frame 1.
Since it is not necessary to form the mounting groove for accommodating the latch seat 12 and the concave groove for accommodating the overhanging piece 10 as in the related art, the labor for the groove processing is reduced by that much, and the The tool can be installed easily and quickly.

Then, the trowel 4 is inserted into the recess 3, the overhanging pieces 10, 10 are positioned on the end surface of the frame 1, and the latch seat 12 is overlapped on the overhanging pieces 10, 10. At this time, the overhanging pieces 10, 10 are positioned inside the convex portion 13, the mounting screws 18 are inserted into the screw holes 17 and the long holes 11, screwed into the frame 1, and the latch seat 12 and the trowel 4 are attached. It is fixed to the frame 1.

After attaching the latch receiving member in this manner, the latch 15 attached to the door 2 is actually inserted into the trowel 4, and it is checked whether there is a gap e between the latch 15 and the inner surface of the side wall 6. If the gap e is equal to or larger than the allowable amount, the mounting screw 18 is slightly loosened, a suitable tool such as a screwdriver is inserted into the troyoke 4, and its tip is inserted into one of the side walls 6, 7 of the troyoke 4. Pushing, the trowel 4 is moved to the left or right by a predetermined amount, and the mounting screw 18 is screwed again to confirm the gap e, and adjust the gap e to a permissible amount or less.

In this case, since the latching piece 16 is arranged so as to be able to be engaged with the notch groove 9, the trojanoke 4 moves while its posture is restricted, and the amount of movement is determined by the latching piece 16 moving to the latching wall 8. It is regulated by contact.

The situation of the trowel 4 after the adjustment is as shown in FIGS. 1 to 3, in which the latch seat 12 is located on the end face of the frame 1 and the projection 13 projects forward. In this case, the side end of the projection 13 is exposed on the frame 1, and a gap is formed between the frame 1 and the projection 13, and the gap is formed between the projecting piece 10 and the latch seat 12. The thickness is small to the extent that the thickness is added, and the inner part is closed by the side wall 7 of the troyoke 4, so that the appearance of the part is not impaired. It is desirable to attach a suitable sealing member and close the gap.

When the door 2 is closed after the latch holder is attached, the tip of the latch 15 engages with the latch guide 20 and rides on the latch seat 12, slides on its flat side end, and then slides on the convex portion 13. The user moves upward and is inserted into the latch housing hole 5 through the opening window 14.

After the door is closed, when the door 2 vibrates due to wind pressure or the like, the latch 15 engages with the inner surface of the side wall 6 of the troyoke 4 to generate a contact sound. However, as described above, the gap e is adjusted to an allowable amount or less. Therefore, occurrence of the abnormal noise is prevented.

In addition, since the trowel 4 is made of a synthetic resin, the effect of absorbing the vibration, impact, abnormal noise, and the like when the latch 15 is engaged with the side wall 6 is increased as compared with a metal troyoke. The latch seat 12 is prevented from becoming loose and quiet.

[0022]

As described above, according to the first aspect of the present invention, the projecting piece and the latch seat are overlapped on the end face of the frame body, and the convex portion is provided on the surface of the latch seat. Since the overhanging piece is accommodated between the inner surface of the frame and the end face of the frame, the minimum current processing of forming a concave hole in the frame is sufficient, and the conventional latch seat and overhanging piece are accommodated. This eliminates the need for groove processing, thereby reducing the time and labor required for processing the frame and simplifying the mounting.

According to the second aspect of the present invention, the protrusion is projected from the surface of the latch seat by substantially the thickness of the projecting piece, so that the movement of the trowel can be promoted. According to the third aspect of the present invention, since the protrusion is formed wider than the lateral width of the overhanging piece and the troyoke is disposed so as to be movable in the left-right direction, the gap between the latch and the troyoke can be adjusted so that when the door vibrates. , Can be prevented from occurring. According to the invention of claim 4, since the troyoke is made of synthetic resin, the vibration and abnormal noise of the latch can be absorbed, the loosening of the troyoke and the latch seat and the quietness can be improved, and the troyoke can be manufactured at low cost. There are effects such as being able to do.
