  Each shoe box 2 of the shoe locker is provided with a door 3 to which a handle 5 having a latch device 4 of the present invention is attached. When the door 3 is opened / closed by the handle 5, the latch device 4 is actuated to open the closed door 3 or keep the opened door 3 closed. .

  As shown in FIGS. 2 to 4, in the latch device 4, a substantially rod-like latch 7 is fitted in a lateral direction via a spring 8 in a latch case 6 protruding from the open end of the door 3 of the shoe box 2. Thus, the latch 7 slides in the latch case 6 so that the head 7 a can be moved in and out of the latch case 6. Then, when the door 3 is opened and closed, the head 7a can be freely engaged with and disengaged from the body frame 8 of the shoe box 2, and the door 3 in the closed state is opened or opened as described above. It can be kept closed.

  The head 7a of the latch 7 has an inner wall surface 9a and is provided with a sand passage hole 9 penetrating from the upper surface to the lower surface. The outer shape of the head 7a is substantially triangular in the illustrated case. Although it is in a shape, it can also be made into a substantially cylindrical shape, a substantially sectoral shape, or the like. The inner wall surface 9 a serves as a closing lid for the latch case 6 when the latch 7 is fitted into the latch case 6.

  The spring 8 is a thin rod-shaped coil spring. One end is supported by a support hole 10 formed in the body portion 7 b of the latch 7, and the other end is brought into contact with the inner wall surface of the latch case 6. An urging force is applied when sliding in the case 6. The latch 7 is provided with a guide body 11 in the length direction of the latch 7 protruding from the rear end of the body portion 7b and a retaining body 12 of the latch 7 protruding from the side surface of the body portion 7b. When the latch 7 slides in the latch case 6, the guide body 11 can freely protrude and retract from a guide hole 13 provided in the rear wall of the latch case 6, and the retaining body 12 is provided on the side wall of the latch case 6. The latch 7 slides smoothly in the latch case 6 and prevents the latch 7 from jumping out of the latch case 6.

  The planar shape of the sand passage hole 9 is a substantially triangular shape along the outer periphery of the top surface of the head portion 7a of the latch 7 having a substantially triangular prism shape, or the top surface of the head portion 7a of the latch 7 having a substantially cylindrical shape. It can be made into a substantially circular shape along the outer periphery, or a substantially fan shape along the outer periphery of the top surface of the head 7a of the latch 7 having a substantially fan-column shape. Furthermore, the opening edge of the sand passage hole 9 is provided with an inclined surface 15 inclined at an inclination angle of 30 to 75 degrees toward the inside of the hole, preferably at an inclination angle of 45 to 60 degrees.

  However, since the earth and sand that has fallen on the head 7a of the latch 7 of the latch device 4 passes through the sand passage hole 9 of the head 7a and falls down as shown in FIG. There is almost no accumulation on the top surface. In the case where the inclined surface 15 is provided at the opening edge of the sand passage hole 9, since the earth and sand slide down the inclined surface 15, the earth and sand do not accumulate on the upper surface of the head 7a. Since the latch case 6 is closed by the inner wall surface 9 a of the sand passage hole 9, the earth and sand do not enter the latch case 6 when the earth and sand pass through the sand passage hole 9.

  Therefore, in the latch device according to the present invention, even if the shoe locker is used frequently for a long period of time, the sand does not accumulate on the upper surface of the head portion 7a of the latch 7, and the head of the latch 7 is opened when the door 3 is opened and closed. Sediment does not enter the latch case 6 from the upper surface of the portion 7a, and malfunction does not occur, and the opening / closing operation of the door 3 of the shoe box 2 can always be performed normally.
