Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a convenient waving device that can mark the vertical position on the floor and ceiling surfaces when installing a partition.

[Conventional technology]

Conventionally, when installing a partitioning member vertically for partitioning a room, use a commercially available swinger to align the lower end of the weight of the swinger with the floor reference point set at a predetermined position on the floor, and then While holding the swinger, touch the swinger body to the ceiling to mark the ceiling reference point, and use the two points, the floor reference point and the ceiling reference point, to vertically install the partitioning member. It is common that

However, with this method, when marking the reference point on the ceiling surface, it is necessary to hold the sagittarius in one hand while holding a pencil or the like in the other hand to mark the ceiling surface. It has the disadvantage that it cannot be attached and that it is very tiring as it requires both hands.

[The problem that the idea attempts to solve]

The technical object of the present invention is to solve the above-mentioned drawbacks and to provide a swinger that can easily mark reference points on a ceiling surface.

[Means to solve the problem]

The present invention will be described below with reference numerals used in the drawings for easy comparison with the drawings showing an example of implementation.

A drum body consisting of a leaf spring winding drum 20, a thread winding drum 14, and a leaf spring drum 15 arranged coaxially is provided inside the body 1 of a size that can be held by hand. 16 is wound around one end of the leaf spring 16, and the other end of the leaf spring 16 is wound around the leaf spring 15, the hanging string 3 is wound around the thread winding drum 14, and this hanging string 3 is formed in the main body 1. A weight 4 is attached to the lower end of the hanging line 3, and a marking part 19 having a marking body 7 for marking the ceiling surface 6 is formed on the upper part of the main body 1, and the marking body 7 is attached to the weight 4. The marking body 7 is provided so as to be movable up and down at a position above the axis, and the marking body 7 is provided so as to protrude upward from the opening 12 on the top surface of the main body 1 due to the elasticity of the spring 10 fitted onto the marking body 7. This relates to a swinger characterized by being provided with a slide lid 13.

[Effect]

Grasp the main body 1 and lift the main body 1 to a position where the top surface of the main body 1 is close to the ceiling surface 6, and align the lower end of the weight 4 of the swinger with the floor reference point marked on the floor in advance. In this state, the marking body 7 is made to protrude upward from the opening 12 on the top surface of the main body 1 to mark the ceiling surface 6.

Since the marking body 7 is placed above the weight axis, the mark made on the ceiling surface 6 can move the floor reference point to the ceiling. By using the points, for example, it is possible to install a vertical partitioning member.

In addition, the thread winding section 2 of the present invention has a so-called constant torque spring structure in which when the weight 4 is lifted, the hanging line 3 follows it and is quietly wound around the thread winding drum 14, so that the pulling out and rewinding of the hanging line 3 is smooth. It will be held in

〔Example〕

The marking part 19 in the drawing is provided with a storage part 8 with a fixing plate 9 for storing a marking body 7 filled with ink and formed so that the ink oozes from the top surface near the top of the main body 1. The spring 10 is inserted through the body 7, the spring 10 is supported on the inner surface of the fixing plate 9, and the marking body 7 is made to protrude from the opening 12 provided on the top surface of the main body by the push-up piece 11 attached to the marking body 7. The figure shows the case where the

The marking body 7 in the drawing has a structure in which ink oozes from the entire top surface of the circular shape, so the center of the circular outline is the ceiling surface reference point, but the center position of the marking body 7 is the indicated point of the weight 4. If there is a slight deviation from the marked position, calculate the interval of the deviation and set the ceiling reference point at a position shifted by that interval from the marked position.

In addition, in order to obtain an accurate position above the four axes of the weight, the position above the weight axis on the top surface of the marked body 7 (marked body 7 in the drawing)
In this case, it is convenient to form a point protrusion at the center position of the circular contour.

Further, although the drawing shows a case where the marking body 7 filled with ink is employed, the marking body 7 may be a needle rod, and the ceiling surface 6 may be marked with the tip of the needle rod. Also good.

Reference numeral 13 in the figure indicates an opening 12 when the marking body 7 is not required.
It has a sliding lid to close it.

The thread winding section 2 in the drawing has several thread winding drums 14 and leaf spring drums 15 mounted on the same axis.
A plate spring winding drum 20 is provided at a position opposite to the line winding drum 20, and the tension of the hanging line 3 is kept constant by setting the restoring force of the plate spring 16, and when the weight 4 is lifted, the hanging line 3 follows it and moves to the line winding drum 14. This is a case where a so-called constant torque spring structure that is wound quietly is adopted.

Reference numeral 17 in the figure is a resistance pin for adjusting the tension of the hanging line 3 (the number of resistance pins and the friction coefficient of the pin surface
Adjust the tension. ), code 18 bearing shaft, code 21
2 is a plate spring fixing pin, and 22 is a vertical line of the weight core.

[Effect of idea]

The present invention provides a swinging device for marking ceiling surfaces that is configured as described above and can easily mark a ceiling reference point on a ceiling surface and exhibits excellent practical effects. .
