Description

[Detailed description of the invention] The present invention relates to an improvement of a bobbin bobbin spool, and its purpose is to make it easy and quick to attach the bobbin bobbin bobbin, regardless of the location and the material. To provide an extremely convenient bobbin bobbin spool that can be attached.

The present invention will be explained below based on an illustrated embodiment.
1 is a case, and the case 1 consists of a side lid part 4 having a base 3 on which a bobbin drum 2 or the like is set, and an outer shell 5 that fits into the lid part 4 and houses the base 3.

Inside this case 1, as described above, the peg drum 2 and the resistance rod 6 are installed, and the peg drum 2 is provided with the base plate 3.
The thread winding spring 8 is connected to the other end of a thread winding spring 8 which is connected to the upright drum core 7 and has one end fixed to the drum core 7, and is constantly elasticized in one direction. The thread 9 wound around the bobbin drum 2 as it becomes energized has one end connected to the thread outlet hole 1 protruding from the outer shell 5 of the case 1.
It extends from 0, and a plumb 11 is attached to the extending end.
are connected.

Further, the resistance rods 6 are made of a plurality of rods arranged irregularly and planted in the base 3 in the vicinity of the yarn exit hole 10, and the aforementioned yarns 9 are entangled with these resistance rods 6. The load of the plumb bob 11 and the tension of the bobbin spring 8 are balanced by the frictional resistance.

The outer surface of the one side lid 4 of the case 1 is provided with several types of attachment means depending on the various types of attachment points.

That is, an arc-shaped concave surface 12 is formed on the outer surface of the lid 4, and a permanent magnet 13 for attaching iron parts such as formwork pipes is embedded in the concave surface 12. A groove 14 is formed for fitting into an angle material for an aluminum sash or a wooden frame, and a stepped portion 15 is provided in the deep part of the groove 14 to ensure proper fitting even when applied to several types of angle materials with different thicknesses. It is possible to maintain the fit.

Further, a cylindrical hole 16 is formed below the permanent magnet 13, and this cylindrical hole 16 enables fitting and holding of the separator.

Furthermore, a needle exit hole 17 is formed in the upper position of the lid 4, and an installation needle 18 built into the case 1 is provided through this needle exit hole 17 so as to be freely protruding, retractable, and rotatable. ,
The installation needle 18 is equipped with a stepped locking handle 19 at its base end, and the handle 19 is inserted into a hole 20 formed in the side surface of the outer shell 5 opposite to the lid part 4 so as to always protrude. A handle 19 is attached to the installation needle 1B by a spring 21 wound around the needle.
It is elastically biased toward the side.

However, in the present invention, when fixing the case 1 to a place, the lid part 4 of the case 1 is fixed according to the members of the place.
The attachment provided in
As shown in the figure, for example, if the location is wood A, the installation is done by driving the installation needle 1B into the wood surface A, and by hitting the head of the handle 19 on one side of the case 1 with a mallet etc. The case 1 can be fixed by a simple operation of pushing the installation needle 1B through the exit hole 17, and the installation can be easily done by rotating the handle 19 when removing the case 1 from the location. needle 18
can be pulled out.

In addition, when the part is made of a gold-layered material such as iron, it is attached by a permanent magnet 13, and in the case of a formwork pipe b, the arcuate concave surface 12 of the lid part 4 is brought into contact with the surface of the formwork pipe 16. For example, the magnetic force of the permanent magnet 13 allows the magnet to be properly attracted and held.

Furthermore, when mounting on a concrete wall C surface, the cylindrical hole 16 may be fitted to the end of the separator d which is buried in the concrete wall e and protrudes from the wall surface. In the case of angle material e, attachment is achieved by fitting the end of the angle material e into the groove 14, and since a step is formed at the depth of the groove 14, the thickness of the angle material e It can be applied regardless of the difference in size.

As explained above, the present invention consists of means for attaching several types of attachments to the case, so no matter what kind of member the case is attached to, it can be fixed and held accurately with extremely simple work. It has great practical effects, such as being simple in structure and inexpensive to provide.
