2. Description of the Related Art Generally, it is known that a toilet seat for a person to sit on is provided on the upper part of the toilet bowl, and the back portion of the toilet seat is hinged to the back portion of the toilet bowl to open and close the toilet seat. In this case, when you sit on the toilet seat or stand up, you will have a middle waist posture.For example, when you use it by an elderly person or a physically handicapped person, especially your legs and waist are weak,
Every time a toilet seat is used, people with disabilities are easily distressed.

Therefore, conventionally, a toilet seat that covers a toilet bowl is placed on a toilet cover, the toilet cover is fixed to a vertical lifting device arranged on the side of the toilet bowl, and the toilet cover is lifted up and down. It has already been proposed that the person can be moved up and down so that a person does not have to take a middle waist posture. By moving the toilet seat up and down in this way, it is not necessary to take a middle waist posture by setting an appropriate height when sitting or standing up on the toilet seat.

[0004]

However, the shape of the conventional toilet cover is only for covering the upper part of the toilet bowl, and when the toilet cover is raised, the toilet bowl and the vertical lifting device in the toilet space are completely visible. Since it does not have a clean appearance and the fingers can touch the toilet bowl, the vertical lifting device, etc., there is a concern that fingers may be stuffed when the toilet cover is lifted, especially for elderly people and people with disabilities. There was a safety issue.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to have a good external shape and a good design, and moreover, the finger touches the toilet bowl, the vertical lifting device, etc. by the toilet cover. It is to provide a toilet bowl cover that can prevent the above-mentioned problem and can improve safety without worrying about finger stuffing.

The recesses 53 for preventing finger stuffing are formed in the respective recesses, and the recess width of the recess 53 on the center side toward the rear side B is set to the recesses 5 on both end sides.
It is preferable to set the width larger than the width of the recessed portion 3 toward the rear B. With this configuration, each toilet cover 51, 5
The space formed by the recess 53 on the center side of 2 can be made wider than the space formed by the recess 53 on both end sides, so that, for example, the upper toilet bowl cover 52 is vertically moved up and down in a forward tilted posture. Even when it is necessary to secure a large space between the central portion 52a of the upper toilet bowl cover 52 and the central portion 54a of the cover portion 54 as in the case of performing the above, it becomes possible to sufficiently cope with it.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described as a case where a vertical movement device 1 is provided on both sides of a toilet bowl 2. As shown in FIG. 2, a front toilet cover 51 having a width dimension obtained by subtracting a predetermined gap from the width dimension of the toilet space 50 is installed along the front shape of the toilet bowl 2 at the front F of the toilet bowl 2. . In addition, above the toilet bowl 2, the front toilet cover 5
An upper toilet cover 52 having a width dimension substantially the same as that of 1 is arranged. Both ends of the upper toilet bowl cover 52 are fixed to the toilet bowl cover mounting portion 16 (see FIG. 13) of the vertical lifting device 1 shown in FIG. 3, and the upper toilet bowl cover 52 is vertically movable. The upper toilet cover 52 is shown in FIG.
As shown in (a), it is possible to select either one of a case of moving up and down while maintaining horizontal, and a case of moving up and down in a forward tilted posture with a slight angle as shown in FIG. 4 (b). Is done. The operation of the upper toilet cover 52 will be described in detail with reference to FIGS. 7 to 16.

Here, the central portion 51 of the front toilet cover 51
As shown in FIG. 5, “a” projects forward of both end portions 51b. In FIG. 5, reference numeral 55 denotes a pad to be applied to the toilet bowl 2, and reference numeral 56 denotes a fixing fitting to the up-and-down lifting device 1. on the other hand,
At the front end of the upper toilet cover 52, as shown in FIG.
A cover portion 54 is provided that hangs downward and covers the front of the front toilet cover 51 so as to be openable and closable. This cover part 54
The central portion 54a of the front portion projects toward the front of each end portion 54b, and when the upper toilet cover 52 is lowered, the central portion 54a and both end portions 54b of the cover portion 54 are located at the central portion 51a and both ends of the front toilet bowl cover 51. It covers the front of the portion 51b.

In order to prevent fingers from being caught between the upper toilet bowl cover 52 and the front toilet bowl cover 51 when the upper toilet bowl cover 52 moves up and down, as shown in FIG.
