Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door latch device, and more particularly to a door handle of a heavy product such as a washing machine, a vacuum cleaner, a dryer, etc., which is compactly stored in a housing. The present invention relates to a provided latch device.

[0002]

2. Description of the Related Art As a latch device for a door such as a locker, the internal storage space in a housing is expanded, and when the door is opened and closed, the latch device is opened and closed by one-touch operation in relation to a pulling handle of the door. A method that can perform the above operation accurately and smoothly has been known (see Japanese Utility Model Publication No. 1-189999).

[0003]

However, the above-mentioned prior art is not suitable for a latch device of a door for storing a heavy-weight washing machine, a vacuum cleaner, a dryer and the like in a housing, and particularly a link lever and a door. Since the connection of the latch bolts was connected by a wire, the extension of the wire itself deteriorated the function of the latch, and there was a problem that the fine adjustment was frequently required. In view of this point, the present invention provides a latch device provided on a handle portion of a door which does not require fine adjustment by using a simple configuration, a link lever shape, and a flat bar instead of a wire. It is intended to provide.

[0004]

According to the present invention, in order to solve the above-mentioned problems, a handle is provided on an upper portion of a surface of a door, and the handle is supported at both ends so as to be parallel to the surface of the door. A latch lever is provided between the handle and the door, and the latch lever is attached to the back side of the door with an interval enough to allow a finger to be inserted through the arm and the connecting member. In the device, a latch device is provided on the back of the door
The support plate for the latch device is attached.
The part is provided with a mounting member for the latch device. This mounting
The member has a link lever that engages the lower end of the connecting member.
The attached horizontal frame member is provided so that it can rotate,
An engaging piece at the upper end and a protruding piece at the lower end that engages the flat lever
A link lever with a
You. Furthermore, a configuration is adopted in which a bent portion bent into a U-shape at the upper end engaging with the protruding piece and a flat lever having a latch bolt at the lower end are connected.

[0005]

[Function] The present invention adopts the above configuration,
By using a simple structure, instead of a wire, a wide flat bar is bent and used by engaging with a link lever, elongation is eliminated and fine adjustment is unnecessary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. First, referring to FIG. 1, which schematically shows the entirety of a storage cabinet A for heavy objects, a door 1 on which a heavy-weight washing machine, a vacuum cleaner, a dryer, and the like are placed on the back side is pulled out and washed. In such a case, in the conventional case, the door 1 is provided with a window portion for four to five fingers, but this is unstable as a pulling handle and cannot be pulled out smoothly. The handle 3 is wide enough to be gripped by both hands so that it can be pulled out smoothly. This handle 3
Are provided with support arms 4 at both ends, and are fixed to the surface 2 of the door with appropriate fixing tools. A latch lever 6 is mounted between the handle 3 and the door 1. It goes without saying that the mounting position of the latch lever 6 may be shifted to the left or right. Next, a specific embodiment of the latch device 8 will be described with reference to FIGS. 2 to 5. As can be seen from the exploded view shown in FIG. 3, the handle 3 is attached to the surface of the door 1 via the support arm 4. Is fixed. A latch device support plate 12 is attached to the back surface of the door 1, and a latch device attachment member 15 is provided in a concave portion of the latch device support plate 12. The horizontal frame member 1 to which the link lever 9 is attached, which engages with the lower end of the connecting member 7
1 is provided so as to be rotatable, provided with a concave portion 10 so as to be rotatable by the horizontal frame member 11, and further provided with an engagement piece 1 at an upper end.
6 and a link lever 9 having a protruding piece 19 at the lower end for engaging with the flat bar 14 are rotatably mounted.
Further, a bent portion 5 bent in a U-shape at an upper end so as to engage with the protruding piece 19 and a flat bar 14 having a latch bolt 13 at a lower end are connected to each other. Although a plurality of the link levers 9 are alternately assembled in the illustrated embodiment, an engaging piece having a U-shaped cross section is used instead of the engaging piece 16 to form one link lever, and the recess 10 is formed with a through hole. Then, it goes without saying that the same purpose and effect can be achieved. The operation will be described below.
When the latch lever 6 is squeezed with the axial direction as a fulcrum, the connection member 7 slides, and the engagement is provided at the upper end of the link lever 9 engaged with the lower end of the connection member 7 with this sliding. The link lever 9 is rotated by the piece 16. By this rotation, the projecting piece 19 provided at the lower end of the link lever 9 rotates upward. By this rotation, the bent portion 5 provided at the upper end of the flat bar 14 engaged with the projecting piece 19 is pulled up, and the latch bolt 13 provided at the lower end of the flat bar 14 moves upward. The lock is released, and the door 1 can be pulled out toward the user. 4 and 5, the grip 3, the latch lever 6, the connecting member 7, the link lever 9, the latch device support plate 12, the latch bolt 13, and the mounting structure of the latch device 8 to the latch device support plate 12 are shown in FIGS. The associated configuration of each of the flat bars 14 is shown. One end of the link lever 9 and a mounting member of the latch bolt 13 are connected by a flat bar 14, and a connecting member 7 is mounted on the other end of the link lever 9 so as to interlock with the latch lever 6. As shown in FIGS. 2 to 5, the engagement piece 1 provided at the upper end of the link lever 9 is also provided.
6 is provided at a lower portion, and a bent portion 21 serving as a stopper which hits the back surface of the front surface portion 2 of the door when pulled by the handle 3 is formed at the upper portion. At a substantially central portion, an arm portion 17 that penetrates an appropriate number of doors 1 and is fixed to the latch lever 6 with a fixture is attached. The horizontal frame member 11 is rotatably inserted into the concave portion 10 or the through hole provided in the link lever 9, and both ends are rotatable by the mounting member 15 of the latch device mounted on the latch device support plate 12. It is provided in. The latch device support plate 12 is provided with a latch device mounting member 15, which engages and connects the horizontal frame member 11 to the mounting member 15, and further has a recess capable of housing the connecting member 7 and the link lever 9. It is provided. The latch bolt 13 is urged to be always locked by a compression spring 18 provided thereon. When the latch lever 6 is pulled forward by overcoming the compression spring 18, the latch bolt 13 is moved to the arm 17, the connecting member 7, the link lever 9, and the flat bar 14.
And the door 1 can be pulled out. At this time, the wire itself was elongated in the conventional one, and the function of the latch was deteriorated. However, since the flat bar was replaced, the extension was lost.

[0007]

According to the present invention, the following effects can be obtained based on the above configuration. (1) Compared with the conventional one, when the door is opened, the flat bar itself connecting the link lever and the latch bolt does not extend, so that there is no need for fine adjustment. (2) Smooth opening / closing can be performed only by changing only the link lever and the flat bar using almost all of the members of the conventional latch device. (3) While unlocking of the latch bolt is performed with one touch, the operation of the door body can be easily opened and closed because the operation is accurately transmitted by the link lever and the flat bar.
