Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a slide ruler and a method for measuring a side panel of a round staircase using the slide ruler.

[Conventional technology]

On the sides of roundabouts and other single-touch staircases, great care is taken when measuring the positions for fitting the step plates and height plates.

For this reason, conventionally, a draft was drawn on a plywood board, cardboard, etc. using a curved scale, and this was then transferred to the actual stair side board material.

By the way, for example, in a staircase having a round staircase part (hereinafter referred to as a round staircase room) 50a as shown in FIG. The above-mentioned position of the step plate 50a was measured as follows because the dimensions of the step plate fitting portion were different for each step.

That is, the side plates 51, 52a, 52 for each step
The length dimensions of 53, 54, 55a, 55b, and 56 and the heights h of these steps are connected, for example, in an L-shape at right angles, as shown in FIGS. 5(A) and 5(B). This was done by drawing ranks-shaped lines.

In FIGS. 5(A) and 5(B), two stair side panels 60 and 61 are prepared, and one of the panels 60 is used for the side panels 60 and 61 on opposite sides of the stairwell 50a (51 and 52a in FIG. 4). ,
55b, 56), and the other plate 61 is used as the front side plate (52b, 53, 54, 55a in Fig. 4).
The length and height h of each side plate are drawn as crank-shaped lines on each plate 60 and 61 as shown in the figure.

Of course, as mentioned above, after drafting the crank-shaped line on the plywood board etc., the above actual stair side board material 60.61
The line is drawn between

To draw lines on the plate materials 60 and 61, first draw the height hl of the first stage on the plate material 60, connect it at right angles to the height and draw the length of the side plate 51, and then draw the length of the side plate 51. The height h2 of the second stage is drawn by connecting at a right angle to the length, and the length of the side plate 51 is drawn by connecting at a right angle to the height h2. This operation is performed to increase the height of the 6th and 7th steps, h, y and the side plate 55.
The same process is performed for the length of b and 56.

Next, after drawing the length of the front side plate 52b of the second stage on the plate material 61, the height h3 of the third stage is drawn at right angles to the length of the side plate 52b, and the height h3 is The length of the side plate 53 is drawn by connecting it at right angles. Repeat this operation in the fourth
Height of step, Length of side vi54, Height of 5th step hs
+ Do the same for the length of the front side plate 55a of the fifth stage.

After the above line drawing is completed, the plate material 60 is cut at a portion corresponding to the height h& of the sixth stage (indicated by a two-dot chain line in the figure).

[Problem to be solved by the invention]

By the way, it is important that the wire drawing be done in the center of the plate material 61, 62 and be done accurately.

If a line is not drawn in the center, the edges will protrude,
In addition, if this is not done accurately, fitting of the step plate, etc. may become impossible, and the plate materials 61 and 62 may be wasted.

However, conventional line drawing (i.e., measuring) work has to be done entirely by the intuition of the worker, and a high degree of skill is required of the worker in order to eliminate waste of board materials61,62. .

For this reason, the efficiency of conventional wire drawing work is low (if there is no highly skilled worker, the efficiency is low).

The present invention makes it extremely easy to draw lines (i.e., measure) work for parts with different dimensions, such as the side panels of round staircases and other staircases, or the side panels of round stairs, without requiring a high degree of skill. ruler, which can be done
The purpose of this invention is to propose a method for measuring the side panels of a winding staircase using the ruler.

[Means for Solving the Problem] In order to achieve the above object, the slide ruler of the present invention has the following features:
One arm having a generally angular shape has a dovetail groove on one side, and the other arm has a protrusion on a surface opposite to the above-mentioned surface that can be slidably fitted into the dovetail groove, When a member having the same shape as the member or a shape in which the arms are arranged on opposite sides is fitted with the arms having the above-mentioned fittings, at least one side of the fitted arms of both members. It is characterized in that the sides are arranged in a straight line.

Further, a locking means may be provided at an appropriate location on at least one arm of the above-mentioned member.

Furthermore, the measuring method of the side plate of the round staircase of the present invention using the above-mentioned slide ruler is as follows: (1) A fitting element different from the roughly angled-shaped arm of another member is attached to one of the roughly angled-shaped arms. mate the arms having the
After sliding these two arms and adjusting them to a predetermined size, these two arms are fixed by a locking means, and the other arm of the other member is attached to the other arm of the other member, which is different from the above-mentioned arm of the other member. After fitting the arms with the mating elements and adjusting the dimensions to the specified size by sliding both arms, the arms are fixed by the locking means, and the above operations [1] and [2] are repeated for a specified number of times. The method is characterized in that the predetermined number of slide rulers are connected and combined by following the slide rulers, and the predetermined number of the combined slide rulers are applied to the side plate material to draw a line.

[Effect]

In the ruler of the present invention, the dovetail groove on one arm and the protrusion on the other arm of the roughly slit-shaped member act as a fitting.

That is, one arm of one member (for convenience, referred to as arm α) has one arm of another member (for convenience, referred to as arm β. The arm β has a fitting different from the arm α. ) are slidably fitted.

In this fitted state, both arms slide freely,
The length of the arm is freely adjusted to the desired length dimension.

Furthermore, in the ruler of the present invention, the length can be fixed to the adjusted length dimension using the locking means.

In the method of the present invention using the above-described rulers of the present invention, several rulers of the present invention are connected and assembled in a predetermined round staircase dimension using the above-mentioned fittings, and this connected and assembled state is fixed by the above-mentioned locking means.

This fixed, connected combination is placed on the stairway side board material and drawn (that is, measured).

〔Example〕

FIG. 1 is an external view showing one embodiment of the ruler of the present invention, and FIG. 2(A) is a cross-sectional view of one arm 1a of the roughly L-shaped member on the member of the ruler of the present invention shown in FIG. FIG. 2(B) is a sectional view of the other arm 1b.

In FIG. 2(A), the bottom surface of the arm 1a is provided with a dovetail groove 2 at the center of the arm, which slopes from the dovetail groove 2 toward both sides, and the top surface is at the center of the arm. Each screw hole 3 is provided, and a screw 4 is inserted into the screw hole 3.

In FIG. 2(B), a protrusion 5 that fits into the dovetail groove 2 is provided at the center of the top surface of the arm 1b, and is inclined from the protrusion 5 toward both sides. There is.

The end portions of the arms 1a and 1b configured in this manner are in contact with each other, forming a roughly slit-shaped member top as shown in FIG.

As shown in FIG. 1, the protrusion 5' of the arm lb' on the other member having the same structure as above is slidably fitted into the dovetail groove 2 of the arm 1a on this member. One embodiment of an inventive ruler is constructed.

At this time, the arms 1a on both members 21' are fitted together.

One (in this example, both) sides of lb' are arranged in a straight line.

In the example shown in FIG. 1, the above two members are fitted together so that the soil ′ is roughly U-shaped, and the screw 4 is inserted into the screw hole 3 of the arm la on the members, and the arm of the member 1′ is assembled. By fixing 1b, "-' is connected and combined on both members, but this is not limitative. Instead of member 1', a member in which the arms 1a and lb of member 1 are arranged in reverse can be used to create a crank. It is also possible to connect them by fitting and fixing them in a shape (not shown).

However, as in this example, on the two members, each arm 1a of soil'
If the lengths of lb, la', and lb' are the same, fit the protrusion on one arm of the other member (not shown) into the dovetail groove 2' on the member being connected and slide it. In order to make the length of the arm of the other member shorter than the length of this arm, it is impossible to do so with a crank-shaped joint assembly, and it is necessary to make the length dimension of the arm of the other member shorter than the length of this arm. Needless to say, it won't happen.

Further, a scale (not shown) may be displayed on the member, the bottom surface and/or the top surface of the soil.
