Abstract

PURPOSE:To make small an expensive metal latch without damaging the strength thereof, to reduce a cost and to make lightweight by forming an interlocking side among interlocking grooves of a latch body of the metal latch, and forming the end side of a synthetic resin latch only. CONSTITUTION:An interlocking side 9 to require strength among U-shaped interlocking grooves 4 is formed of a metal latch 7 of chrome molybdenum steel, and the end side 10 to simply rotate the latch body 1 only is formed of a synthetic resin latch 8 of polyester elastomer. The entirety of the interlocking side 9 and a shaft-hole 2 are formed of the metal latch 7, and the end side 10 of the remainder of approximate 1/3, the front end 13 thereof and the periphery of the metal latch 7 are formed of the resin latch 8. According to the constitution, unpleasant sounds in the case a door is closed are reduced and, at the same time, costs can be reduced.

However, it is impossible to reduce the thickness of the metal latch f in terms of strength, so considering the nature of the latch for a vehicle locking device, a substantially U-shaped engagement that does not require strength as a structure. This was devised by cutting out the abutting side of the groove. As a result, there is no need to worry about strength, and the cost can be reduced considerably and the weight can be reduced, so we propose the following.

That is, FIG. 2 shows the latch main body l and the striker 3 in the door open state, and when the door is closed, the striker 3 moves along the movement trajectory Y'2 and comes into contact with the abutting side 10 of the engagement groove 4. Then, rotate the latch body ]- to engage with the engagement groove 4 as shown in Fig. 1, and in the closed state, the engagement side 9, which is the non-abutting side, engages with the striker 3. This will keep the door closed. For this reason, the engaging side 9 of the latch body 1 is required to have strength as a structure, but the abutting side 10 simply rotates the latch body 1 by contact with the striker 3. This eliminates the need for expensive and heavy metal latches. Therefore, in the present invention, the engagement side 9 of the U-shaped engagement groove 4 is formed with a metal latch 7, and the abutment side 1 is formed with a metal latch 7.
0 is formed of a synthetic resin latch 8.

Therefore, in the present invention, as described above, the reasonably expensive metal latch 7 is made smaller than in the known example, so that the cost and weight can be reduced without sacrificing its strength. In addition, as in the known example, the abutting side 10 is connected to the metal latch 7.
If the door is formed with resin, the metal portion will act as a reverberating member and produce unpleasant noises, but since no metal is used on the abutment side 10, the sound when the door is closed can be further reduced.
