Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a lid device for a washing machine.

(b) Conventional technology This type of lid, which is opened and closed manually, was developed in 1973.
A handle is provided as shown in Publication No. 34687,
Further, as shown in Japanese Patent Publication No. 50-34863, opening and closing is made possible by providing a space between the top plate and the mounting recess for the fingers to enter.

On the other hand, as shown in Japanese Utility Model Application Publication No. 58-174089, in which the lid is divided into two parts, the structures shown in FIGS. 2 and 3, A, B, and C are adopted. In the figure, 1 is a machine frame of a fully automatic washing machine, 2 is a top plate, and 3 is a resin-made inverted dish-shaped top cover that opens and closes a clothing opening on the top plate. The upper lid 3 is divided into front and rear lids 4, 5, and the rear end of the rear lid 5 is pivotally supported on the upper surface plate 2, and the front and rear lids 4, 5 are connected by a hinge structure so that they can be bent to each other. Reference numeral 6 denotes a handle, and 7 a recess for gripping the handle, which are each integrally formed on the front lid 4. Reference numeral 8 denotes an opening formed to form the handle 6, which is covered by a cover 9. The cover 9 comes into contact with the back surface of the lid, and
It overlaps with the connecting end of the recess 7 from the back side. and,
The elastic claws 10, 10 formed on the inner surfaces of both side walls,
It is engaged from the side with engagement holes 12, 12 of hanging pieces 11, 11 that are integrally provided on the back surface of the lid.

In this way, the cover 9 is fixed from the back side of the lid, but when an external force is applied to the connecting portion (seam) 13 of the recess 7, a large step is generated, which may catch fingers during opening/closing operations. In addition, the elastic claws 10,1
There was a risk that buttons and pins would fall into the tank from the die-cutting holes 14, 14 for forming 0.

(c) Problems to be solved by the invention This invention improves the adhesion between the cover and the recess by improving the fixing structure of the cover, and eliminates the need for punching holes. .

(d) Means for solving the problem The present invention has an insertion hole integrally formed along the lid surface at the end of the concave portion connected to the cover, and a tongue piece inserted into the insertion hole in the cover. The problem is solved by integrally forming protruding claws and ribs on the outer surface of the recess and the cover that elastically engage with each other in the anti-insertion direction.

(e) Action: In other words, the cover is moved along the lid surface, the tongue piece is inserted into the insertion hole, and supported from both the front and back sides, and when an external force is applied, both the cover and the recess move in the same way, and the gap between the two is 〓 Don't make any pauses. In addition, claws and ribs that engage with each other are located on the unnecessary outer surface of the die-cutting hole, and both of them are finally engaged only by the movement of the cover.

(F) Embodiment This will be explained based on FIG.

Reference numeral 15 denotes a connecting end of the recess 7 with the cover 9, the end surface of which abuts the end surface of the connecting end 16 of the cover 9, or a support piece that is bent and extends forward, facing the end with a slight distance. 17 supports the back surface of the connecting end 16. Reference numeral 18 denotes a stopper which is formed to bulge backwards at the connecting end 16 of the cover, and is substantially flush with the support piece 17.

Reference numerals 19 and 19 denote thick-walled portions formed at two locations on the connecting end portion 15 of the recessed portion 7, and insert holes 20, 20, a portion of which is formed by the support piece 17, are formed toward the rear from the end surface. The insertion holes 20, 20 are molded together with the lid 4 using a simple mold from the front and back.
For this purpose, the support piece 17 is cut forward in the thickened portions 19, 19. That is, these cuts 21, 21 become die-cut holes, and these holes are
It is almost entirely hidden by the connecting end 16 of.

Reference numerals 22, 22 are tongue pieces formed protruding from the end surface of the connecting end 16 of the cover 9 in correspondence with the insertion holes 20, 20, and are inserted into the insertion holes 20, 20.

23, 23 are claws formed protrudingly on both outer surfaces of the cover 9; 24, 24 are elastic ribs protruding from both outer sides of the recess 7 and extending forward; When inserted into the insertion holes 20, 20, the claws 23, 23 elastically engage the ribs 24, 24 in the counter-insertion direction.

When installing and securing the cover 9,
is positioned on the back side of the front lid 4 and slid backward. Then, the tongue pieces 22, 22 are inserted into the insertion holes 20, 20, and the claws 23, 23 engage with the ribs 24, 24 around the time when their end surfaces abut each other.

After installation, even if an external force is applied to both connecting ends 15, 16, since the tongue pieces 22, 22 are sandwiched from both the front and back sides, both ends 15, 16 will move together, and a large step will not be created at seam 13. There is no.

(G) Effects of the invention According to the invention, there is no need to create a step at the joint between the cover that covers the opening on the back of the handle and the recess, and accidents such as getting your fingers caught and hurt during opening and closing operations can be prevented. In addition, the processing of the end face becomes easier and the cost of the mold can be reduced.
