Description

[Detailed explanation of the invention] "Purpose of the invention" (Field of industrial use) Low tanks installed in toilet rooms in hotels, etc. are equipped with a front plate that visually blocks the low tanks. be. This idea is
In the structure in which the operating handle is attached to the low tank configured as described above through its front plate, the mounting position of the operating handle can be adjusted so as to eliminate problems caused by misalignment between the low tank and the front plate. This invention relates to a new low tank operation handle mounting structure.

(Prior Art) FIG. 2 is an exploded perspective view showing a conventional low tank operating handle mounting structure for easy understanding. As shown in the figure, a front plate 5 is attached to the front side of the low tank 6 (the side facing the toilet bowl) to visually block the low tank 6. Although not shown, the front plate 5 is provided with a shelf, a drawer, etc., and is used as a storage space for small items when using the toilet. The low tank 6 has a front wall 6a thereof.
A mounting boss portion 1 is fixedly fixed therethrough, and a suspension lever 2 bent into an L-shape toward the inside of the low tank 6 is pivotally attached to the mounting boss portion 1 . Also, the hanging lever 2
A ball tap (only the chain 7 for suspending the ball tap is shown in the drawing) is suspended from the tip of the tank 6 to normally close the outflow of the cleaning water stored in the low tank 6. Further, a handle shaft 3 is connected to the mounting boss portion 1 so as to protrude in a direction opposite to the suspension lever 2, and is rotatable on the same axis as the suspension lever 2 through serration fitting. It's summery. The handle shaft 3 has a loose fitting hole 5a bored in the front plate 5.
The operating handle 4 is attached to the protruding end 3a. Therefore, by rotating the operating handle 4 on the front surface of the front plate 5 so as to push it down, the handle shaft 3 and the suspension lever 2 rotate around the mounting boss portion 1, and are suspended from the tip of the suspension lever 2. The ball tap is pulled up from a flush water outflow opening (not shown) in the low tank 6, and flush water is then supplied to the flush toilet bowl.

(Problems to be Solved by the Invention) As shown in FIG. 2, in the conventional mounting structure of the operating handle 4, the mounting boss 1 is fixed to the front wall 6a of the low tank 6, and the handle shaft 3 is fixed to the front wall 6a of the low tank 6. It is inserted into a loose fitting hole 5a of the front plate 5. Therefore, when installing the low tank 6 and the front plate 5, the problems shown in FIGS. 3A to 3C will occur unless the mutual positional relationship between them is carefully matched. That is, if the installation interval between the low tank 6 and the front plate 5 is too wide as shown in FIG. However, on the contrary, if the installation interval between the low tank 6 and the front plate 5 is too narrow as shown in FIG. It ends up looking unattractive. Furthermore, as shown in FIG. This caused a problem in the operating state of the operating handle 4. If the mounting position of the operating handle 4 has a problem as described above, it is completely impossible to adjust it due to its mounting structure, and the mutual positional relationship between the low tank 6 and the front plate 5 must be adjusted to a predetermined position. There was no other option but to fix it.

The present invention has been developed in view of the above-mentioned circumstances, and the operating handle has the ability to adjust its mounting position so as to eliminate problems caused by misalignment between the low tank and the front plate. The purpose of the present invention is to provide a new low tank operation handle mounting structure (hereinafter referred to as the proposed mounting structure).

``Structure of the invention'' (Means for solving the problem) The main points of the mounting structure of the present invention are: a bracket that clamps and holds the upper edge of the side wall of the low tank; a mounting flange attached to an oblong hole drilled in the flange, a suspension lever for a ball tap pivotally attached to the mounting boss, and a handle coaxially connected integrally with the suspension lever. The low tank front plate includes a shaft, a low tank front plate having a loose fitting hole for the handle shaft, and an operating handle attached to the tip of the handle shaft.

(Function) The mounting boss portion is attached to the low tank via a bracket and a flange. Since the bracket is attached by clipping the upper edge of the side wall of the low tank, it is movable along the upper edge direction of the side wall of the low tank (the front-rear direction with respect to the front plate), and can move along the upper and lower edges of the upper edge. It is also possible to move in any direction. Further, the flange is provided to cross the bracket at right angles, and has a horizontally elongated hole for attaching a mounting boss portion. In other words, the horizontally elongated hole of the flange is bored horizontally parallel to the installation surface of the front plate, and the mounting boss section attached to the horizontally elongated hole cannot be moved in the horizontal direction with respect to the front plate. It's becoming possible. In this manner, the mounting position of the mounting boss portion can be adjusted in the vertical and longitudinal directions using the bracket, and can be adjusted in the horizontal direction using the flange. In other words, it is not only possible to adjust the mounting position of the mounting boss part while checking the loose fit state of the handle shaft inserted into the loose fit hole of the front plate, but also to adjust the mounting position within the range where smooth operation of the ball tap is desired. If so, the operating handle can be attached to any position on the front plate without being restricted by the position of the low tank.

(Examples) The present invention will be described below based on drawings showing examples thereof.

FIG. 1 is an exploded perspective view showing the mounting structure of the present invention for easy understanding. As shown in the figure, the most important feature of the mounting structure of the present invention is that the mounting boss portion 1, which determines the mounting position of the operating handle 4, is mounted to the low tank 6 via a bracket 8 and a flange 9.

The bracket 8 is made of a stainless steel plate with a thickness of 2 to 3 mm and has a bent U-shape in cross section, and is configured to sandwich the upper edge 6b of the side wall of the low tank 6. Screw holes 8a, 8a for fixing bolts 10, 10 are bored in the bracket 8 by burring or the like, and the tightening force of the fixing bolts 10, 10 and the repulsive force of the other side plate surface 8b are combined. Therefore, it is designed to be clamped to the low tank 6. For reference, the burring process will be briefly explained. Burring is a processing method mainly used in sheet metal presses, etc., and is used to make taps for screws, bolts, etc. that have a pitch larger than the wall thickness on thin plate-like objects. Then, drive a taper punch or the like with the desired pilot hole size of the female screw into the planned position for drilling the screw hole, bulge an annular burr on the back side of the plate-shaped object, and tap the inner peripheral surface of the burr. A method of establishing a In the bracket 8 of the proposed mounting structure, the above-mentioned burring process is performed to widen the threaded contact area of the fixing bolts 10, 10, thereby making the clamping state between the bracket 8 and the low tank 6 strong. There is.

The flange 9 is a plate-like member that is integrally bent from one side of the bracket 8, and intersects the upper edge 6b of the side wall of the low tank 6 held by the bracket 8 at right angles. The flange 9 is provided with a horizontally elongated hole 9a for the attachment boss 1.

On the back side of the mounting boss portion 1, there is a rectangular parallelepiped-shaped boss portion 1a that is fitted into the horizontally long hole 9a of the flange 9.
is formed. The length of one side of the boss portion 1a is
The length of the short side of the flange 9 is approximately equal to the width of the horizontally elongated hole 9a, so that it can be moved laterally while being held in the horizontally elongated hole 9a. This mounting boss portion 1 is attached to a seat nut 11.
It is clamped to the flange 9 by.

Note that the other configurations of the mounting structure of the present invention are substantially the same as those of the conventional one. That is, the hanging lever 2, which is bent into an L-shape toward the inside of the low tank 6, and the handle shaft 3, which is loosely fitted to the front plate 5, are pivotally attached to the mounting boss portion 1 so as to protrude in opposite directions. be done. A ball tap (not shown) is suspended from the suspension lever 2, and an operating handle 4 is attached to the tip 3a of the handle shaft 3.

(Study of Alternative Embodiments) The bracket 8 and the flange 9 do not need to be integrally formed by bending, and may be joined by welding or the like. Further, if possible, screwing or the like may be used. Also,
The fixing bolt 10 that is screwed onto the bracket 8 may be one that passes through the low tank 6 and is screwed onto the other side plate surface 8b. In this case, it is preferable that the opening area of the bolt hole formed in the side wall surface 6b of the low tank 6 is made as large as possible. Needless to say, this is a measure to widen the adjustment range of the bracket 8.
Further, although the handle shaft 3 is shown as being a separate member, it goes without saying that the pivot shaft of the suspension lever 2 may be extended toward the front plate. In this way, the configuration and shape of the mounting structure of the present invention can be changed as appropriate depending on the mode of implementation.

"Effect of the invention" As is clear from the above explanation, according to the mounting structure of the low tank handle according to the invention, the mounting boss part that determines the mounting position of the operating handle can be moved vertically and longitudinally by the bracket. The flange allows for adjustment in the left direction. Therefore, it is not only possible to adjust the loose fitting state of the handle shaft inserted into the loose fitting hole of the front plate, but also the low tank is not restricted in any way as long as it is within the range where smooth operation of the ball tap can be expected. The operating handle can be attached to any position on the front plate. In other words, whereas in the past, the position where the operating handle was installed was set based on the installation position of the low tank, in the proposed mounting structure, the mounting position of the operating handle was set based on the user's usability. It has an epoch-making effect. In addition, as mentioned above, since it is possible to insert the handle shaft into the loose fit hole in the front plate in an appropriate state, it is possible to reduce the hole diameter of the loose fit hole (see Figures 1 and 2). (see comparison), you can expect even better visual shielding and dust-proofing effects.
Furthermore, since there is no need to drill and form a mounting hole for the mounting boss in the low tank, there are many excellent advantages such as improved efficiency and lower costs in the manufacturing process of the low tank.
