[Industrial applications]

 A structure of a tape measure that transforms into a kind of pipe, which gives expansion restoring force to the material in the process of manufacturing and forming the tape measure, and when the tape measure is pulled out and used, both sides are circularly bent toward the center to form a pipe shape. As a result, there is no phenomenon that the tape measure bends when the user measures the scale, and it is a new type of creation that is highly practical without the inconvenience and harmful effects of conventional products.

[0002]

[Prior art]

 The “tape measure” is a scale measuring tool that is now commonly used in general construction and households, and has the following advantages.

(1) It has a small volume and is light and convenient to carry. The main body of the tape measure is made of a metallic material that has flexibility for weighing, and since it can be easily rolled into a small housing case, it is convenient to carry.

(2) A latch is provided at the front end of the tape measure body, and the container is provided with a stop button for preventing shrinkage. The user fixes the length of the tape measure by hooking the tip of the tape measure to the end of the object to be measured, pulling out the tape measure, and pressing the stop button at the desired length. Therefore, the user can easily measure the length of the object and read the numerical value accurately without the need for an assistant.

(3) A restoring spring plate is provided on the tape measure shaft portion, and when the user releases the stop button that was being held when the tape measure body was housed in the container, the elasticity of the restoring spring plate was changed. The tape measure body is quickly rewound into the container, which is convenient and practical.

(4) The tape measure body has several kinds of graduations. For example, it has centimeters (meters), inches (feet), and scale units that are commonly used in Taiwan, making it versatile and highly practical.

As described above, the structure of the tape measure according to the present invention has many features. On the contrary, it is also true that the traditional tape measure has the drawback that the user hates it for a long time. That is, in the conventional products, the material of the main body of the tape measure is light and highly flexible.Whenever it is used, it bends due to the soft bending phenomenon, and smooth and quick measurement cannot be performed. It was inconvenient.

As shown in FIGS. 1 and 2, this is an example of use of a conventional tape measure. However, when the tape measure body is pulled out to a certain length, a soft bending phenomenon always occurs and the tape measure bends downward. Or, there was a problem that the front and back were reversed. In addition, permanent folds remained on the tape measure body with the lapse of use period, making it difficult to proceed with the measurement smoothly. Furthermore, as the creases are generated, the scale scale engraved on the main body of the tape measure falls off or disappears.Furthermore, after a certain period of time, creases frequently occur on each part, corners are raised and smoothness is lost, and dimensional accuracy is also reduced. As a result, the service life of the tape measure is greatly shortened.

[0009]

[Problems to be solved by the device]

 In light of the above, the creators have studied the defects of conventional products based on their experience of many years in the work of the road and pursued improvement measures. We devised a tape measure that deforms into a pipe or a tube that is marked by the product, and after innumerable use and verification, we confirmed that the effect of the present invention is certain, and the product of the present invention is a conventional product. It is positioned as a new type of device that eliminates the harmful effects that appear and seeks to gain the recognition of society as a highly practical tape measure structure.

[0010]

[Means for Solving the Problems]

 An object of the invention of the tape or the tape-shaped deforming tape measure according to the present invention is to provide a new type and highly practical tape measure structure. In other words, when the tape measure body is pulled out from the case and used when the tape measure body is extended and restored, the material used in the manufacturing process of the tape measure is automatically wound toward the center. Then, the main body of the flat tape measure comes to form a pipe shape. Therefore, the main feature of the tape measure is that it softly folds during use, which prevents inconvenience in use.

【Example】

 In the preferred embodiment of the present invention shown in FIG. 3, the container 1 for accommodating the tape measure main body and one holder hook provided on one side of the container 1 are shown as a main structure. ) 2, a stop button 3 for preventing shrinkage on another side of the container 1, a semi-arc type passage 11 under the stop button 3, and a tape measure main body 4 pulled out from the semi-arc type passage 11 In addition, a latch 41 is provided at the tip of the tape measure body 4.

FIG. 4 is a cross-sectional view of an embodiment of a good result according to the present invention. That is, one central shaft column 12 is provided in the center of the container 1, and one groove 121 is cut in the longitudinal direction of the central shaft column 12, and the central shaft column 12 has a hollow shaft ring. 13 is fitted and the tape measure body 4 is wound tightly on the attention of the axle ring 13. Further, a shaping ruler 14 is provided midway between the hollow shaft ring 13 and the semi-arc type passage 11. After the tape measure body 4 passes through the shaping ruler 14 in a flat state, it passes through the semi-arc shaped passage 11.

A latch 41 is fixed to the tip of the tape measure body 4, and a spring 15 is attached to the central space of the hollow shaft ring 13. The open end side of the spring 15 is concavely folded. It looks like an S-shape and is inserted into the groove 121 of the central shaft column 12.

A knock button (stop button) 3 for preventing contraction is provided above the semi-arc type passage 11, one end of which forms a swinging portion 31, and which is tightly attached to a pressure plate (32) below the swinging portion 31. It becomes a state.

When the user now uses the tape measure 4, the length of the object can be measured immediately by pulling out the tape measure body 4 by hand. At this time, when the user pulls out the tape measure main body 4 to an appropriate length, the swinging part 31 of the knock button 3 for preventing host accommodation can press the pressure plate 32 to fix the tape measure main body 4 at that position.

[0016]

[Effect of device]

 The characteristic of the tape measure structure deforming into a pipe or a tube according to the present invention is that when the tape measure body 4 is pulled out from the container 1, both sides of the tape measure body 4 are automatically crimped toward the central part, It is in the form of two pipes. This is to give the expanded restoring force to the material in the process of manufacturing and molding the tape measure body 4 by making full use of the heat treatment technology.

As shown in FIGS. 5 and 6, when the tape measure body 4 is used, both sides of the tape measure body 4 are crimped toward the central portion due to the restoring action generated by the expanded restoring force of the material itself. It is transformed into a tubular shape.

When the tape measure body 4 is housed in the container 1, the tape measure body 4 deformed into a tubular shape by the shaping action of the shaping ruler 14 is restored to a flat body and housed in the container 1, and the hollow shaft ring 13 inside Can be rolled up around.

Therefore, the structure of the tape measure according to the present invention has an advantage that is different from the conventional traditional products.

The advantages are listed below in a number of features.

1. Do not bend. That is, the user can easily and accurately measure the length. This is a new concept that eliminates the soft bending phenomenon found in conventional products.

2. Practical use without the situation that the tape maker's service life is significantly shortened due to the accumulation of the soft folding phenomenon, which often occurs in conventional products, and the permanent creases that occur in the pile. And economic.

3. The tape measure body according to the present invention forms a pipe shape when used, and does not cause soft bending. Therefore, the user does not have any inconvenience in vertical height measurement, and is highly practical.

Summarizing the above, the tape-shaped tape measure according to the present invention is novel and highly practical both in terms of its structure and function.
