Abstract

PROBLEM TO BE SOLVED: To make it possible to utilize a tape measure for other than length measurement and measuring purpose without human work by attaching a magnet to the outer surface side of an attaching metal piece at the tip of the graduation band of the tape measure. SOLUTION: A magnet 13 is rigidly fixed to the outer surface of an attaching metal piece 16 by bonding and the like after fixing the L-shaped attaching metal piece 16 to the tip of a graduation band 12. In the use of a tape measure, when the graduation band 12 is withdrawn from a case 11 with the tip of the graduation band 12 being made to approach a magnetic strut, the tip of the graduation band 12 is attracted to the strut and slidden up by the action of the magnet 13. Therefore, the graduation band 12 is not bent in the halfway and is withdrawn with the extended state being maintained. When the tip of the graduation band 12 reaches the position of a beam, the magnet 13 is surely attracted to the beam. Thus, the measurement of the height is smoothly performed without human work. The measurement in the lateral direction can be performed without another man's cooperation. Furthermore, when a compact iron member or the like is dropped during high-place working, the dropped material can be smoothly picked up from the high place by attracting the dropped material with the magnet 13.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape measure for measuring length and distance.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a tape measure of this type is composed of a case 1 and a metal plate or a plastic plate having a spring property. It is generally known to have a graduation band 2 in which a graduation 3 is applied to the graduation band 2 and an L-shaped hook 4 is fixed to the end of the graduation band 2.

In the conventional tape measure having the above-described configuration, the scale band 2 is pulled out of the case 1 to a desired length to measure the length (distance) of an object to be measured. There is no inconvenience when measuring a short one. However, measuring a long object has the following problems. That is, for example, when measuring the height, when the scale band 2 is pulled out from the case 1 by a predetermined length or more,
Since the scale band 2 was bent, the intended purpose could not be achieved (see FIG. 2). In the case of measuring in the horizontal direction, the conventional tape measure has a hook 4 at the tip of the scale band 2. However, since the metal bracket 4 alone tends to come off, it is necessary to borrow the help of another person to make the scale band 2 It is very inconvenient to use it by holding the tip or holding it with a weight.

[0004] By the way, small members such as tools and bolts are often dropped during work at a high place, for example. In addition, it is extremely difficult to pick up an object dropped in a narrow place.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and a tape measure that can be used for a long measurement without any human intervention and that can be used for purposes other than measurement. It is intended to provide.

[0006]

In order to achieve the above object, a tape measure of the present invention is a tape measure in which a scale band having a spring property is wound in a case and is housed in a drawer-free manner.
A magnet is mounted on the outer surface of a mounting bracket fixed to the end of the scale band.

[0007]

According to the present invention, the following functions are provided.
For example, when measuring the height of a structure constructed of steel, when the scale band is pulled out of the case while the tip of the scale band is close to the main pillar (made of steel) of the structure, the tip is attracted to the main column by a magnet. Since the scale band is slid up, the scale band is drawn out while being extended without being bent in the middle unlike a conventional product, and the tip of the scale band can reach the target position. When the tip of the scale band reaches the target portion, the magnet is securely attracted to the target portion (made of steel), so that the height can be measured smoothly.

For example, when measuring the length of a steel material such as an H-shaped steel, when the tip of the scale band comes into contact with a target portion of the steel material, the tip is securely attracted and fixed to a predetermined portion by a magnet. By retreating, the scale band can be pulled out smoothly. Therefore, it is possible to measure the length of the steel material smoothly and without using the cooperation or weight of another person as in the related art.

For example, when a small member such as a tool or a bolt is dropped while working at a high place, the tip of the scale band is brought into contact with the dropped object while the scale band is pulled out of the case, or a thin string is tied to the case. When the user wears the tape and hangs the tape measure, and touches the tip of the scale band with the dropped object, the dropped object is attracted to the magnet, so that the dropped object can be pulled up without falling down as in the related art. In addition, objects dropped in a narrow place can be picked up in the same manner as described above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a perspective view a showing an embodiment of a tape measure constructed in accordance with the principle of the present invention, and a plan view b showing a part of a scale band. FIG. 2 is a height measurement between the tape measure and a conventional tape measure. FIG. 3 is an explanatory diagram showing the operation when measuring in the horizontal direction using the tape measure, and FIG. 4 is an explanatory diagram showing an example of a usage method other than the measurement of the tape measure. It is.

1 to 4, a tape measure according to the present embodiment includes a case 11, a graduation band 12 which is wound inside the case 11 and is housed in a removable manner,
2 and a magnet 13 attached to the tip of the second magnet.

The case 11 is made of plastic or the like, and has a size such that the scale band 12 can be wound and housed therein. 14 are formed.

The graduation band 12 is made of a steel plate or a plastic plate having a spring property, and a graduation 15 is marked on the surface of the graduation band 12. The width and length of the graduation band 12 can be arbitrarily determined. However, in a normal case, the width and length of the graduation band 12 can be determined in a range of about 1.5 to 2 cm and a length of about 5 to 8 m. It seems that there are many. However, this does not limit the above dimensions.

The magnet 13 is attached to the tip of the scale band 12, and in this embodiment, the magnet 13 is
An L-shaped mounting bracket 16 is fixed to the end of the mounting bracket 16 and firmly fixed to the outer surface of the mounting bracket 16 by bonding or any other means. As the magnet 13,
It is preferable to use a strong magnet having a large attraction force. In this embodiment, a configuration in which the lateral length of the magnet 13 is formed to be longer than the width of the graduation band 12 to increase the attraction force is disclosed.

The illustrated tape measure is constructed as described above. Next, an example of the method of using the tape measure and the operation thereof will be described. FIG. 2 is an explanatory view showing an operation of the tape measure of the present invention and a conventional tape measure when measuring the height of a structure constructed of steel material, in which 21 is an H-shaped steel or an iron square pipe. The reference numeral 22 denotes a beam made of H-shaped steel or the like. Therefore, for example, when measuring the height up to the beam 22, in the tape measure of the present invention, as shown in FIG.
Is pulled out of the case 11, the tip of the scale band 12 slides up while being attracted to the main pillar 21 by the action of the magnet 13, so that the scale band 12 is pulled out while maintaining an extended state without being bent in the middle, The tip of the scale band 12 can reach the position of the beam 22. When the tip of the scale band 12 reaches the position of the beam 22, the magnet 1
Since the beam 3 is surely attracted to the beam 22, the height can be measured smoothly. On the other hand, in the conventional tape measure, as shown in FIG. 4B, when the scale band 2 is pulled out from the case 1 by about 1 m or more, the scale band 2 is bent in the middle, so that the expected result is obtained without the cooperation of another person. The goal cannot be achieved.

FIG. 3 is an explanatory view for explaining the operation in the case where the measurement in the horizontal direction is performed. FIG.
An example of measuring the length of the mold steel 23 is disclosed. Therefore, in the tape measure of the present invention, when the tip of the scale band 12 contacts a target portion (the end of the steel 23 in the drawing), the tip of the scale band 12 is firmly attracted and fixed to a predetermined portion by the magnet 13. Therefore, the scale band 12 can be smoothly pulled out by retracting the case 11 in this state. Therefore, the length of the steel 23 can be measured smoothly and smoothly without using the cooperation or weight of others.

FIG. 4 is an explanatory view showing an example of a use method other than the measurement of the tape measure according to the present invention. FIG. 4 shows a small-sized tool such as a spanner 25, a driver 26 or a bolt 27 while working at a high place of a building 24. There is disclosed an example in which when steel members are dropped, these members are picked up while staying at a high place. That is, when the small member as described above is dropped while working at a high place, the scale band 12 is pulled out of the case 11 and the scale band 12 is pulled out.
When the tip of the scale 11 comes into contact with a dropped object (for example, a spanner 25) or a thin string (not shown) is attached to the case 11 to suspend the tape measure, and the tip of the scale band 12 contacts the dropped object, the dropped object Since it is firmly adsorbed, it is possible for the worker 28 to smoothly pick up a dropped object while staying at a high place without falling down. In addition, the object dropped in a narrow place can be picked up by the same method as described above.

[0018]

According to the present invention, in addition to the measurement in the horizontal direction and the measurement in the height direction, the measurement of a curved object or the like can be performed smoothly without the cooperation of others, and the small iron member is picked up. And a tape measure that can be used for purposes other than measurement.
