Description

[Detailed description of the device]

[0001]

[Industrial applications]

 In this invention, for example, when fixing the main body of a lighting fixture to the ceiling by screwing, screws such as wood screws are temporarily held at the peripheral edge of the mounting hole of the main body of the fixture and screwed into the mounting hole of the main body of the fixture. The present invention relates to a screwing guide jig for guiding a.

[0002]

[Prior Art]

 For example, when fixing the main body of lighting equipment to the ceiling surface or wall surface with wood screws, fix the main body and wood screws with one hand while holding the wood screw with a tool such as a screwdriver with the other hand. It is necessary to tighten.

[0003]

[Problems to be solved by the device]

 However, in the conventional installation work of the equipment, it was necessary to temporarily hold both the equipment body and the wood screw with one hand, and the workability of attaching the equipment was poor. In addition, the workability was also poor in that the wood screws tended to fall when tightening them. Therefore, an object of the present invention is to provide a screwing guide jig capable of improving the workability of attaching the device.

[0004]

[Means for Solving the Problems]

 The screw-fastening guide jig of this invention is one in which one end surface is magnetically attracted to the peripheral edge of the mounting hole of the device to be screwed while holding the screw for mounting the device. At least one end of the magnet is a magnet, and holding means for holding the screw inside the cylinder is provided so that the screw can advance in the axial direction of the cylinder.

[0005]

[Action]

 According to the configuration of the present invention, one end surface of the tubular body holding the screw on the device in advance is attached to the peripheral portion of the mounting hole of the device to be screwed, so that the screw is temporarily held, and the ceiling of the device is fixed. ， Equipment can be installed simply by holding the device with one hand when mounting it on the wall.

Further, since the holding means holds the screw inside the cylinder so that the screw can enter in the axial direction of the cylinder, when the screw is tightened with the tool, the screw does not fit into the attachment hole of the instrument. It is kept in a substantially vertical position to prevent the screw from tilting during tightening. Further, since the holding means holds the screw in a state in which it can enter in the axial direction of the tubular body, it passes through the tubular body when entering the ceiling or wall surface by tightening the screw. Therefore, it can be removed when the temporary holding of the screw becomes unnecessary after the screw is completely tightened or during the tightening.

【Example】

 [First Embodiment] A first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, this screw-fastening guide jig has two horizontal sides of two semi-cylindrical bodies 1 and 2 each of which is a permanent magnet and has a horizontal cross section of a substantially arc shape. The hinges 3 are rotatably connected so that the inner arc surfaces face each other.

Both half-cylindrical bodies 1 and 2 have one end surface (the lower end surface in the drawing) formed flat, and the other end surface (the upper end surface in the drawing) is provided with a taper 4 for guiding the head of the wood screw. .. Further, the semi-cylindrical bodies 1 and 2 are shown in an open state in the figure, but they are normally in a closed state by a suction action by a magnetic force. This screwing guide jig attracts one end surface magnetically to the peripheral edge of the mounting hole of the device to be screwed while holding the wood screw for mounting the device.

The two semi-cylindrical bodies 1 and 2 rotatably connected by the hinge 3 constitute a tubular body through which a wood screw can pass. The two semi-cylindrical bodies 1 and 2 made of permanent magnets also serve as holding means for holding the wood screw so that the wood screw can enter in the axial direction of the cylinder. As shown in FIG. 2, the screw-fastening guide jig having the above-described structure has the other end surface (upper end surface in the drawing) of the leg of the wood screw 5 made of iron in the space between the semi-cylindrical bodies 1 and 2 in advance. Then, the semi-cylindrical bodies 1 and 2 are inserted while widening the gap against the magnetic force. At this time, the head of the wood screw 5 is exposed to the outside. That is, the legs of the wood screw 5 are sandwiched between the semi-cylindrical bodies 1 and 2.

Then, in this state, as shown by arrows in the peripheral portion of the mounting hole 7 of the iron-made fixture 6 to be screwed such as the fixture main body of the lighting fixture, one end surface of the semi-cylindrical bodies 1 and 2 (see the drawings). Then, the lower end surface) is magnetically attracted, and the wood screw 5 is temporarily held by the instrument 6. After that, the tool 6 is positioned at a predetermined location such as the ceiling surface or wall surface, and then the wood screw 5 is tightened using a tool 8 such as a screwdriver as shown in FIG. Fix it in place.

At this time, since the taper 4 is provided on the other end surfaces of the semi-cylindrical bodies 1 and 2, the head of the wood screw 5 uses the taper 4 as a guide when the wooden screw 5 is tightened. The head of the wood screw 5 pushes the semi-cylindrical bodies 1 and 2 apart without getting caught in the space, and the semi-cylindrical bodies 1 and 2 do not interfere when the wood screw 5 is tightened.

When the tightening of the wood screw 5 is completed, as shown in FIG. 4, the screwing guide jig composed of the semi-cylindrical cylinders 1 and 2 joined by the hinge 3 is removed from the device 6 as shown by the arrow. The attachment of the device 6 is completed. According to this screw-fastening guide jig, one end faces of the semi-cylindrical bodies 1 and 2 are attached to the peripheral edge of the mounting hole 7 of the device 6 to be screw-fastened while the semi-cylindrical bodies 1 and 2 hold the wood screws 5. Since they are attracted by magnetic force, if the wood screws 5 are temporarily held by attracting the semi-cylindrical bodies 1 and 2 holding the wood screws 5 in the peripheral portion of the mounting hole 7 of the device 6 in advance, the ceiling and wall surfaces of the device 6 By simply holding the tool 6 with one hand when attaching it to the etc., the work of mounting the tool 6 can be performed and the workability can be improved.

Further, the wood screws 5 hold the wood screws 5 inside the semi-cylindrical bodies 1 and 2 by an attracting action by magnetic force so that the wood screws 5 can enter in the axial direction of the semi-cylindrical bodies 1 and 2. Therefore, when tightening the wood screw 5 with a tool 8 such as a screwdriver, the wood screw 5 can be kept substantially vertical to the mounting hole 7 of the instrument 6, and the wood screw 5 tilts during the tightening of the wood screw 5. Can be prevented, and workability can be improved in this respect as well.

Furthermore, since the semi-cylindrical bodies 1 and 2 of permanent magnet property hold the wood screws 5 in a state in which they can enter in the axial direction of the semi-cylindrical bodies 1 and 2 themselves, by tightening the wood screws 5, the ceiling or It will pass through the semi-cylindrical bodies 1 and 2 as it enters the wall surface, so remove it after completing the tightening of the wood screw 5 or during the tightening process when the temporary holding of the wood screw 5 becomes unnecessary. You can

In the above embodiment, the outer peripheral surfaces of the semi-cylindrical bodies 1 and 2 are also arcuate, but the outer peripheral surface may have any shape. Also, the shape of the inner peripheral surface may be concave. In addition, in the above-described embodiment, the entire semi-cylindrical bodies 1 and 2 are made of permanent magnets. However, it is not necessary to make the whole of semi-cylindrical bodies as permanent magnets. All you have to do is get it.

Further, the hinge 3 is not limited to one directly formed on the semi-cylindrical bodies 1 and 2, but may be a structure in which the semi-cylindrical bodies 1 and 2 made of a permanent magnet are attached to the iron hinge 3. [Second Embodiment] A second embodiment of the present invention will be described with reference to FIG. As shown in FIG. 5, this screw-fastening guide jig is applied when the device 6 to be attached has a sloppy hole as the attachment hole 9, and the hinge 10 is attached to the semi-cylindrical body 1. , 2 is projected from one end surface (lower end surface in the figure), and is set to fit exactly into the great circle portion of the Daruma hole which is the mounting hole 9.

By setting the shape of the hinge 10 in this way, the semi-cylindrical bodies 1 and 2 can be accurately positioned with respect to the mounting holes 9, and the workability of mounting the device 6 can be further improved. You can The configuration and operation effects other than the above are the same as those of the embodiment shown in FIGS.

[Third Embodiment] A third embodiment of the present invention will be described with reference to FIG. As shown in FIG. 6, this screwing guide jig is such that two semi-cylindrical bodies 11 and 12 connected by a hinge 13 are provided with guide taper 14 and 15 at one end and the other end, respectively. The directionality of the semi-cylindrical bodies 11 and 12 by widening one end and the other end of the semi-cylindrical bodies 11 and 12 from the middle part to increase the area in contact with the device, which improves stability and improves the ability to hold wood screws. It is a thing.
