Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a door latch device, and in particular to a washing machine, a vacuum cleaner, and
The present invention relates to a latch device provided on a handle portion of a door of a heavy product such as a dryer.

[Prior Art] As a latch device for a door of a locker or the like, the internal storage space inside the enclosure is expanded, and at the time of opening and closing the door, the latch device is opened and closed by one-touch operation in relation to the puller of the door. It has been known in the past to accurately and smoothly perform (see Japanese Utility Model Publication No. 1-11899).

[Problems to be solved by the present invention] However, in the above-mentioned conventional technique, it is not suitable for a door latch device for accommodating a heavy washing machine, a vacuum cleaner, a drier, etc. In particular, there was a problem that it was difficult to apply in relation to the handle.

In view of this point, an object of the present invention is to provide a latch device that has a simple structure and is provided with a handle that bears weight and that is provided on a handle portion of a door that is adapted to the handle.

[Means for Solving the Problem] In order to solve the above problems, the present invention provides a latch device provided on a handle portion of a door, wherein a handle is provided on an upper surface portion of the door, and the handle is a surface portion of the door. It is a round bar with both ends fixed by support arms so that it is parallel to, and a recess is formed between this round bar and the door so as to approximately match the arc of the round bar. A lever is provided, the latch lever is provided through the arm portion and the connecting member at a distance such that a finger can be inserted through the door and is connected to the latch device, and the connecting member is an L-shaped link lever. Attach the horizontal frame member that connects the upper part of the and the upper part of the rectangular link lever,
A fulcrum provided at the lower ends of both link levers is rotatably attached to a latch device support plate attached to the back side of the door,
A configuration is adopted in which the other end of the L-shaped link lever and the latch bolt are connected by a wire.

[Operation] By adopting the above configuration, the present invention is provided with a handle that can handle a heavy weight with a simple configuration, and the latch device is concretely adapted to this handle. When pulling out or storing a heavy machine such as a machine or a dryer from a storage case, the latch device can be operated with one touch while grasping the handle.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
First, the first one schematically showing the entire housing A for heavy goods.
Explaining the drawings, a door 1 having a heavy washing machine, a vacuum cleaner, a drier, etc. on the back side is pulled out for washing, and in such a case, the conventional one has four fingers.
Although the door 1 was provided with a window part for about 5 pieces, it was unstable as a puller and could not be pulled out smoothly. The round bar-shaped handle 3 has such a width that it can be held by both hands so that it can be pulled out smoothly. Support arms 4 are provided at both ends of the handle 3 and are fixed to the door 1 by appropriate fixing tools. A latch lever 6 is attached so as to be located between the handle 3 and the door 1. Needless to say, the mounting position of the latch lever 6 may be moved 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 has a support arm on the surface of the door 1. It is fixed through 4. 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 recess of the latch device support plate 12. The latch member 8 assembled by the connecting member 7, the L-shaped link lever 9, the rectangular link lever 10, and the lateral frame member 11 is fixed to the mounting member 15, and the fixed portion serves as a fulcrum 16 to serve as a latch lever. When 6 is squeezed, one end of the L-shaped link lever 9 moves upward, and the L-shaped link lever 9
The latch bolt 13 is moved upward by the wire 14 connected to the door 14, the lock is released, and the door 1 can be pulled out toward the front.

Further, in FIGS. 4 and 5, the recess 5 of the latch lever, which is a configuration for mounting the latch device 8 on the support plate 12 for the latch device,
The respective related configurations of the latch lever 6, the L-shaped link lever 9, the latch device support plate 12, the latch bolt 13, and the wire 14 are shown. One end of the L-shaped link lever 9 and a mounting member of the latch bolt 13 are connected by a wire 14, and a connecting member 7 is mounted on the other end of the L-shaped link lever 9 so as to interlock with the latch lever 6. , An arm portion which penetrates the door 1 through the connecting member 7 and is fixed to the latch lever 6 with a fixing tool.
There are 17. The horizontal frame member 11 is selected in terms of strength as required and is attached or removed.

The latch device supporting plate 12 is provided with a latch device mounting member 15, and the mounting member 15 includes a connecting member 7, an L-shaped link lever 9, a rectangular link lever 10, and a lateral frame member 11.
Is fixedly connected to each other, and a recessed portion for accommodating this is provided.

The latch bolt 13 is biased by a compression spring 18 provided on the upper portion thereof so as to be always locked. When the latch lever 6 is pulled forward by overcoming the compression spring 18, the latch bolt 13 is unlocked through the arm 17, the connecting member 7, the L-shaped link lever 9, the fulcrum 16, and the wire 14. The door 1 can be pulled out. At this time, with the conventional one, the heavy products placed on the rear portion of the door 1 could not be pulled out smoothly. It was made possible.

[Effect of the Invention] The present invention can obtain the following effects based on the above configuration.

(1) Compared to the conventional one, even when a door is pulled out, even a heavy object can be opened and closed very smoothly.

(2) Since most of the members of the conventional latch device are used to widen the pull tab, it is possible to easily open and close a heavy door.

(3) While the latch bolt is unlocked with one touch, the operation is accurately transmitted by the L-shaped link lever and the wire, so that the door can be easily opened and closed.
