Abstract

PURPOSE:To mount and demount the device quickly and be able to mount it with strong holding force by providing a pair of right and left holding movable legs 4 which rotate around a vertical shaft center with respect to a frame and eccentrically rotate back and forth and are connected with each other by means of a turnbuckle mechanism, on the back side of holding fixed legs. CONSTITUTION:On the front side of vertical pipe bodies 2 with which handles 1 are integrally provided, holding fixed legs 3 are fixed in such a way as extending downward, and one sides of crank-shaped holding movable legs 4 are attached to the lower portions of the pipe bodies 2 so as to be rotatable and not to be taken off. On the other hand, a turnbuckle mechanism is installed at pins 11a, 11b in the eccentric portion of a pair of holding movable legs 4. Accordingly, by the operation of the turnbuckle mechanism 5, the wall frame A1 of a bathtub A is held between the holding fixed legs 3 and the holding movable legs 4, and thereby it is mounted and demounted quickly and mounted with strong holding force.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a clamping device for removably attaching a suitable working device or working member, such as a handle or stand, to a wall frame, plate frame, etc. of a predetermined thickness. In particular, this clamping device is widely used when attaching a handle to a bathtub in a bathroom or the like.

PRIOR TECHNOLOGY Conventional clamping devices, as seen in vise fixing devices, use a screw mechanism that runs perpendicular to the fixed leg to bring the movable leg close to each other.51
It was designed to last for 1 hour.

Problems to be Solved by the Invention In the conventional device, the fastening screw of the clamping device is provided in the same direction as the clamping direction, and the head of the screw protrudes perpendicularly to the thickness direction of the frame. The problem was that the screw head protruded from the wall of the frame and got in the way of installation.

Technical Means for Solving the Problems The present invention has taken the following technical means to solve the conventional problems.

That is, it is equipped with appropriate working devices and working members.
・The clamping fixed legs 3 are provided on the machine frame at a constant width or at a constant interval on the left and right sides, and the clamping fixed legs 3, 3 are rotated about the downward axis on the front and rear sides of the clamping fixed legs 3, 3, and A pair of left and right movable clamping legs 4, 4 which rotate eccentrically are provided, and the eccentric rotation positions of the left and right movable clamping legs 4.4 are connected to each other by a turnbuckle mechanism 5 to form a clamping device.

Functions and Effects of the Invention According to the present invention, the movable clamping legs 4, 4 eccentrically rotate about the rotation axis in the vertical direction and approach the fixed clamping legs 3, 3, so that the fixed mounting is fixed to the frame. This makes it possible to securely install the frame even in places where the thickness of the frame varies or is bent, and the left and right movable clamping legs 4.4 are operated in conjunction with each other by the turnbuckle mechanism 5. Not only can it be quickly attached and detached, but it can also be attached with a strong clamping force, and furthermore, the direction of the turnbuckle 5 is in the left-right direction (the attachment is in the direction of the frame), so it has a unique effect that it does not get in the way.

Embodiment An embodiment of the present invention will be described in detail based on the drawings.
A handle 1, which is attached to the wall frame A1 of the bathtub A and serves as an operating member for entering and exiting, is integrally provided on the oil side of vertical cylinders 2, 2 arranged at regular intervals in the left and right direction. The clamping fixing legs 3.3 are fixed so as to extend downward,
A clamping movable leg 4 bent into a crank shape on the cylinder bodies 2, 2;
The upper end side of the cylindrical body 2 is inflated appropriately and the lower end of the cylindrical body 2 is squeezed. A turnbuckle mechanism 5 connects positions appropriately eccentric from the rotation axis. To explain an example of the turnbuckle mechanism 5, the right screw 6
A and a left screw 6b are provided on the left and right sides of the screw 6. The screw 6 is inserted into the cylinder shaft 7 and its center part is firmly supported by the metal 8. This mechanism is configured so that the left and right pipes 9a, 9b can be protruded or retracted by screwing integral nuts 10a, 10b together and rotating the cylinder shaft 7 in the forward or reverse direction. It is pivotally connected to the eccentric portions of the movable clamping legs 4, 4 with pins lla and 1.lb. 12 indicates a rotation operating lever that passes through the left and right center portions of the cylinder shaft 7 and the metal 8 portion.

To explain the operation of the upper side, when installing the handle 1 on the wall frame A of the bathtub A, use the rotary operation lever 12 to move the cylinder shaft 7 in the correct direction.
When the left and right pipes 9a and 9b are both rotated in the opposite direction to project outward, the pin 11a.

The movable clamping legs 4, 4 are rotated in a direction away from the fixed clamping legs 3.degree. 3 and opened via the clamping movable legs 11b. In this state, the wall frame A8 of the bathtub A is fitted from above so as to be sandwiched between the fixed clamping legs 3 and the movable clamping legs 4, and the cylindrical shaft 7 is rotated in the opposite direction using the rotary operation lever 12. Then, the pipes 9a and 9b retract together into the cylinder shaft 7, causing the movable clamping legs 4, 4 to rotate toward the fixed clamping legs 3, 3, and the movable clamping legs 4, 4 to strongly abut against the wall surface of the bathtub A. . In this way, the handle 1 is securely attached to the wall frame A1 of the bathtub A by the fixed clamping legs 3 and the movable clamping legs 4.

When the turnbuckle 5 is installed later, it will be in the direction along the wall frame A□ of the bathtub A, so the screw member etc. as a fastening device will not protrude from the wall of the bathtub A without knowing, and it will be safe. In addition, when attaching and detaching, the left and right clamping movable legs 4, 4
can be rotated all at once, allowing quick attachment and detachment.
