【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view showing a handle latch device according to an embodiment of the present invention. FIG. 2 is a rear view of FIG. 1. FIG. 3 is a longitudinal sectional side view of FIG. 1 showing a closed state. FIG. 4 is a view similar to FIG. 3 showing an open state. FIG. 5 is a side view of FIG. 1 with a main part cut away. FIG. 6 is a perspective view of the spring cylinder.
The main part of the handle latch device 1 is composed of a base 2, a latch body 3, spring receivers 4, 5, a compression spring 6, and a spring cylinder 7, for example, a rear part or a side of a van type vehicle or a marine container. A lock means 8 used at the time of locking the handle H for opening and closing the double door provided at the section, and for holding the latch body 3 at the closed position, at a position shown by a chain line in FIG. Are omitted, and are omitted in this example.
The base body 2 forms a basic part of the handle latch device 1. In this example, the base body 2 has a flat boat shape, left and right long holes 9 on the upper side, left and right through holes 10 near the upper side, and inside thereof. There are left and right U-shaped recesses 11 that are open at the top, an accommodation cavity 12 that accommodates the lower half of the latch body 3 in the middle, and left and right bearings 13 that have a semicircular shape with an open rear. On the lower side, through holes 14 are respectively formed. The through hole 14 is closed by a cap 15 made of an elastic body.
The latch body 3 is provided to be rotatable with respect to the base 2 from a closed position to an open position. In this example, the latch body 3 has a hook shape. In the figure, a C-shaped recess 17 having an open rear is formed, a shaft hole 18 penetrating right and left is formed in the middle, and a spring accommodating cavity 19 which is opened rearward and downward is formed on the lower side. A support shaft 20 is inserted into the shaft hole 18, and its left and right outer protrusions are fitted to the bearing 13 of the base 2.
The spring receivers 4 and 5 are provided on the base 2 and the latch body 3. In this example, the spring receiver 4 has a plane H shape and a substantially Z-shaped side surface, and includes left and right bent pieces 21. A connecting piece 22 for connecting them, and left and right hooking pieces 23 formed on the upper side thereof are provided. The bent piece 21 is attached to the base 2 by four screws 24, and presses the support shaft 20 above the bent piece 21. The lower side of the compression spring 6 is engaged with the upper middle of the connecting piece 22. The latch piece 23 prevents the latch body 3 from rotating beyond the open position. The spring receiver 5 is provided on the rear side of the latch body 3, and is a left-right knock pin facing the spring housing cavity 19 in the middle.
The compression spring 6 is provided between the spring receivers 4 and 5 to hold the latch 3 at the closed position or the open position. In this example, the compression spring is a compression coil spring. It is interposed between the upper side of 22 and the spring receiver 5 which is a knock pin. Thus, the contact point A between the spring receiver 5 and the compression spring 6 is opposed to a line D connecting the connection point 22 of the spring receiver 4 and the contact point B between the compression spring 6 and the center C of the support shaft 20. To hold the latch 3 in the closed position or the open position.
The spring tubular body 7 is undetachably engaged with the two spring receiving bodies 4 and 5 to surround and hold the compression spring 6. In this example, the spring tubular body 7 has a square tubular shape and is manufactured by pressing a flat plate. On the upper side, left and right semicircular notches 25 to be engaged with the spring receivers 5 which are knock pins, and on the lower side, above the connecting pieces 22 of the spring receivers 4 so as not to hinder the rotation of the latch 3. The left and right cutouts 26 each having a semicircular shape are formed respectively. The spring cylinder body 7 is fitted to the compression spring 6 outside and holds it so as not to buckle.
[0007]
Next, the assembling procedure and operation will be described based on such a configuration.
The support shaft 20 is inserted into the shaft hole 18 of the latch 3, and the left and right sides of the latch 20 project outward from the latch 3. The upper half of the latch body 3 is inserted from the rear of the accommodation cavity 12 of the base 2 to be positioned above and forward of the base 2, and the left and right sides of the support shaft 20 are fitted to the bearings 13 of the base 2. The compression spring 6 is inserted into the spring cylinder 7, and the notch 25 on the upper side of the spring cylinder 7 is engaged with the spring receiver 5, and the upper side of the compression spring 6 abuts on the spring receiver 5. The upper side of the connecting piece 22 of the spring receiver 4 abuts against the lower side of the compression spring 6 and is compressed, and the upper side of the connecting piece 22 of the spring receiver 4 is inserted into the lower notch 26 of the spring cylinder 7. The support shaft 20 is held on the bent piece 21 of the spring receiver 4 on the left and right sides thereof, and the spring receiver 4 is attached to the base 2 by four screws 24.
The spring receiver 4 has not only the function of supporting one of the compression springs 6 but also the function of attaching the support shaft 20 to the base 2 so that the base 2 and the latch body 3 are rotatably united. Therefore, assembling is further simplified by employing such a spring receiver 4.
When the latch 3 is turned to the open position as shown in FIG. 4 by pushing the lower side of the latch 3 backward or pulling the upper side of the latch 3 forward from the state of FIG. The rear side of the body 3 abuts on the latching piece 23 of the spring receiver 4 to prevent further rotation, and the contact point A between the spring receiver 5 and the compression spring 6 is compressed by the connecting piece of the spring receiver 4. The latch 3 is located behind the line D connecting the contact point B of the spring 6 and the center C of the support shaft 20, the latch 3 is held in the open position by the compression spring 6, and the handle H is connected to the C-shaped recess 17 of the latch 3. And the U-shaped recess 11 of the base 2.
When the handle H is dropped into the U-shaped recess 11 of the base 2 from the state shown in FIG. 4, the latch 3 is rotated to the closed position as shown in FIG. The contact point A between the spring receiver 5 and the compression spring 6 is brought into contact with the connecting piece 22 of the spring receiver 4, the contact point B between the compression spring 6 and the center C of the support shaft 20. The latch body 3 is located forward of the connecting line D, the latch body 3 is held in the closed position by the compression spring 6, and the handle H is latched by the C-shaped recess 17 of the latch body 3 and the U-shaped recess 11 of the base 2. You.
Spring supports 4 and 5 are directly provided on the base 2 and the latch 3, and a compression spring 6 is interposed between the spring supports 4 and 5, and surrounds the compression spring 6 between the spring supports 4 and 5. Since the spring cylinder 7 for holding the spring is provided, the number of components is reduced, and the spring receivers 4 and 5 do not swing. Therefore, assembling can be easily performed without much trouble and time.
[0008]
In the above embodiment, the spring tubular body 7 has a square tubular shape, but is not limited to this. For example, the spring tubular body 7 may be a cylindrical shape or a polygonal tubular shape other than a square.
The lock means 8 is omitted in the above embodiment, but is not limited thereto, and may be provided, for example.
[0009]
