る。(Prior Art) A frame body that receives a cover body of a manhole or the like is provided with a handle that serves as a handhold for climbing up and down the hole, but the conventional handle has an integral structure with the frame body. Therefore, once the frame is installed, the position of the handle cannot be changed unless the frame is moved. On the other hand, Utility Model Application No. 60-148359, No. 60-148360, No. 60-
No. 148361 has been proposed, but these have a structure in which the base end of the handle is attached in a cantilever manner to the flange on the outside of the frame, and it is necessary to form a hole for attachment in the flange. Therefore, it is not possible to install the handle in a place without a hole, and leaving a hole in a position where the handle is not attached causes an undesirable problem as it may cause water and dust to enter the inside. .

有する。(Embodiment) In the illustrated embodiment, the proposed mechanism is provided on a frame 1 that supports a circular manhole iron cover R and opens and closes in a hinged manner. An engaging portion 6 consisting of a sliding groove 4 and a locking wall 5 extending in a substantially horizontal direction is provided. As illustrated in FIG. 1, the engaging portion 6 of the embodiment includes an inner edge 10 of the frame flange plate 9 and a shelf for installing a receiving piece 11 provided to prevent the tapered iron lid R from digging in. An annular sliding groove 4 is formed by the portion 12, and locking walls 5, 5 are provided protruding from the inner edges of the inner edge portion 10 and the shelf portion 12, respectively. Insertion port 1 without

る。 Fig. 2 shows an example in which the engaging portion 6 is continuously formed on the inner surface of the frame 1 over the entire circumference, and one insertion opening 13 into the sliding groove 4 is formed, and the handle 3 can be slid approximately 360 degrees. It can be moved and placed at any position on the engaging part 6. Third
In the figure, the engaging parts 6 are set to be slightly short, and they are arranged at four equal intervals, with a gap of 1 between each engaging part 6.
4 becomes the insertion port 13. The one shown in FIG. 3 is suitable when the position at which the handle 3 is installed is approximately determined, and furthermore, the attachment position can be adjusted within the range of the length of the engaging part 6.

By screwing the tightening screw 8 into the female threaded part 19 passing through the locking part 7, the tightening screw 8 is pressed against the back wall of the sliding groove, and the head 17 is engaged with the locking parts 5 and fixed. (See Figure 5). Reference numeral 20 denotes a lid hinge holder provided on the inner surface of the frame, but the proposed mechanism is not limited to the hinge type.

付けられるので安全性が増す効果がある。(Effects of the invention) Therefore, according to the present invention, the mounting position of the handle 3 can be set extremely freely, the number of attachments can be set arbitrarily, and the handle 3 is provided at a substantially horizontal engagement portion provided on the inner surface of the frame body. 6, the position can be determined, and it can be fixed at that location, so even after the frame 1 has been installed, it can be moved while considering the relationship with the footrests such as the side blocks, or when opening and closing the lid. This has the effect of allowing you to choose a location where it will not get in the way when the direction changes. In addition, the handhold mounting position can be changed continuously rather than in stages, so it can be mounted at the most appropriate location, thus increasing safety.
Furthermore, there is no need to provide any attachment holes in the frame 1. In addition, in hinge-type manholes, although the opening direction is fixed, the position of the footrest inside may not always be constant, but according to the present invention, one or two handholds 3 are placed in a position where it is easy to enter and exit. This has the effect of increasing safety.
