Description

[Detailed description of the invention] This invention relates to a temporary fixture for hanging appliances, and is mainly used to suspend appliances such as lighting fixtures that are embedded in the ceiling etc. from ceiling slabs etc. When connecting and supporting hanging rod members such as hanging bolts from below, it is possible to confirm the mounting position from below and temporarily fasten near the hanging position, simplifying and speeding up the installation work. The present invention relates to temporary fixing devices for hanging instruments.

Conventionally, when connecting and supporting a lighting fixture that is embedded in the ceiling, etc. from below to a hanging bolt suspended from a ceiling slab, etc., it is necessary to suspend it from the mounting hole drilled in the earthen wall of the lighting fixture. The lower ends of the bolts were aligned and inserted through the bolts, and a nut was secured to the bolts to suspend and fix the bolts.

However, this work must be carried out jointly by one worker who supports the lighting fixture from below and another worker who fastens it with the nuts, which is extremely tedious and especially If the lighting equipment has a considerable weight, it would be almost impossible for a worker to carry out the installation alone.

Therefore, this invention was devised in order to eliminate the drawbacks that existed in the past, and its structure forms a columnar body that can be inserted into the mounting hole of the equipment such as the lighting equipment to be supported. , a removable attachment part for hanging a hanging rod member for hanging instruments is formed on the upper part of the main body, and a guide part for penetrating and connecting with the mounting hole is formed on the lower part of the main body. This consists in that an engagement piece that tilts and protrudes in an orthogonal state and engages with the edge of the attachment hole is built into and pivotably supported in the main body so as to be freely retractable.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

Reference numeral 1 shown in the figure is a columnar body formed so as to be able to be inserted into a mounting hole H drilled in an earthen wall or the like for equipment such as lighting equipment to be supported. It is formed from a gold rod material with a diameter smaller than the diameter.

At the top of this main body 1, there is a mounting part 2 that can be detachably attached to a hanging rod member B for hanging appliances, such as a hanging bolt whose upper end is buried and fixed in the ceiling slab S. is formed.

The mounting portion 2 in the illustrated example has a mounting hole 3 recessed from the upper end surface of the main body 1 along the axial direction of the main body 1 on the inner peripheral surface so that it can be screwed onto a male screw formed at the lower end of the hanging rod member B. It is made by forming an acid screw.

By screwing the suspension member B to the suspension rod member B using such screw means, attachment to and removal from the suspension rod member B can be easily performed by rotating the main body 1 itself.

Of course, the structure of the mounting portion 2 is not limited to the illustrated example, and may be changed to a positive means using a spring piece that can be released by appropriate operation, a pin means that is inserted through a double pipe structure, or the like.

Further, a guide portion 4 for penetrating and connecting with the mounting hole H is formed at the bottom of the main body 1, and this guide portion 4 is cut so that its diameter gradually decreases as it reaches the lower end. This is done so that the substantially tapered lower end can be easily aligned with the mounting hole H.

Reference numeral 5 denotes a guide chain, which is connected in a hanging manner via a connecting ring 7 inserted through a connecting hole 6 bored at the lower end of the guide part 4, and when the main body 1 is attached to the hanging rod member B. Confirm the vertical state of the hanging rod member B itself, and when the hanging rod member B is tilted, correct it to the vertical state by forcibly pulling it through the guide chain 5, and further check the vertical state of the hanging rod member B. This makes it possible to facilitate alignment with the mounting hole H.

An engagement piece 8, which tilts and protrudes outward from the main body 1 in a substantially orthogonal state due to its own weight and engages with the edge of a mounting hole H of an instrument, is built in and pivotably supported in the main body 1 so as to be freely retractable.

The engagement piece 8 is stored with the lower end of the engagement piece 8 in a storage space 9 that is opened along the diameter direction of the main body 1 near the upper side of the main body 1, that is, near the bottom of the mounting portion 2. It is housed by being pivotally supported by a pin member 10 such as a spring pin inserted into the lower part of the gap 9 (see FIG. 6).

At this time, the engagement piece 8 itself is moved by the main body 1 due to the influence of a slight external force.
It is extremely preferable to make the weight balance of the upper and lower portions of the engaging piece 8 unbalanced so that it can swing and protrude outward very easily, so that the storage becomes unstable, so to speak. The width of the upper part is set wider than that of the lower part, and an appropriate weight is attached to the upper part.

In any case, due to the collision with a moving object along the side surface of the main body 1 from below, the engaging piece 8 itself is moved into the storage space 9.
Although it is stored in an upright position within the main body 1, it protrudes from within the storage space 9 after collision with a moving object and is released, and is configured to fully support and engage an object moving downwards in the main body 1. ing.

FIG. 7 shows an embodiment in which a pair of engagement pieces 8 are built in and pivoted in a storage space 9, and by making sure that each of the engagement pieces 8 protrudes in opposite directions, Since the substantial engagement support surface by the engagement piece 8 can be enlarged, this is extremely effective when the attachment hole H is sufficiently large.

Furthermore, if necessary, the engaging piece 8 itself can be made smaller, and the stability of the engagement and support can be increased.

This device is constructed as described above, and its use will now be explained with reference to FIGS. Attach the main body 1 at section 2, and if necessary, adjust the hanging rod member B so that it is vertical (see Fig. 2), and then align it with the mounting hole H drilled in the instrument. Main body 1
Push the instrument upwards through the guide part 4 of the main body 1 so that it penetrates (see Fig. 3), and the edge of the mounting hole H slides into engagement piece 8 protruding outward from the main body 1. While being stored in the main body 1, the engaging piece 8 is once pushed upward from the upper end of the stored state, and then the engaging piece 8, which protrudes outside the main body 1 again, is inserted into the mounting hole H. By being engaged with the edge of the holder, instruments are temporarily secured (see Fig. 4).

After that, the mounting part 2 and the hanging rod member B are separated and the main body 1
By removing this and screwing a nut N or the like to the hanging rod member B, the instruments are fastened and supported in a predetermined position.

In addition, the code|symbol C in the figure is a ceiling board.

Therefore, by attaching the equipment to the lower end of the hanging rod member B corresponding to the position where the equipment should be suspended, and aligning it with the mounting hole H, the equipment can be stored semi-automatically by simply pushing it upward. The protruding engagement pieces 8 can be used for temporary fixing, and each work such as attachment to the hanging rod member B, positioning of instruments, pushing up, etc. can be carried out by the worker alone. , simplification of support work on site,
It becomes possible to speed up the process.

In particular, the engaging piece 8 is pivotably supported in the main body 1 so that it can move outwardly and retractably so that it tilts and protrudes outward from the main body 1 in a substantially orthogonal state due to its own weight, and engages with the edge of the mounting hole H. Now, main body 1
Although it protrudes outward, if the edge of the mounting hole H, through which the instruments are pushed up from below the main body 1, comes into contact with it, it will stand up and be housed inside the main body 1, causing the instruments to be pushed up. It does not interfere with your work at all.

Not only that, when the instrument is pushed up to a predetermined position, the engagement piece 8 semi-automatically swings again and engages the edge of the mounting hole H with the protruding waist protruding, thereby raising the instrument. Moreover, at this time, the oscillating action of the engaging piece 8 does not utilize the elastic straightening force of a spring, etc., so it can prevent impact loads such as instruments. Also, there is no risk of mechanical abnormality, and a smooth and stable oscillating action can be obtained.

The mounting part 2 formed on the upper part of the main body 1 is a removable mounting set for the hanging rod member B, and is designed to connect with the stiff hanging rod member B during temporary fixing work, and to attach the nut N.
When fully fastened, etc., it can be easily removed and used again, which is convenient as it can be used frequently.

In addition, the guide portion 4 formed at the bottom of the main body 1 is designed for penetration connection with the mounting hole H, so that the guide portion 4 formed at the bottom of the main body 1 can be connected to the mounting hole H for tools during pushing up work when it is attached to the hanging rod member B. In addition to being useful for alignment, it also has the effect of making it easier to confirm the mounting position from below, and furthermore, it is easy to handle even if this type of support work is mainly performed at high places. Together with this, extremely safe work can be guaranteed.

Although the figure shows an example where the lighting fixture is suspended and supported, this is not limited to this, and the same applies to other electrical equipment that is connected and supported by the hanging rod member B by being pushed up from below. It is clear that the present invention can be implemented in many ways, and in particular, when supported by a plurality of hanging rod members B, it is suitable for use in supporting heavy instruments.

As explained above, according to this invention, when fixtures such as lighting fixtures that are embedded and supported and fixed in a ceiling etc. are connected and supported from below by a hanging rod member suspended from a ceiling slab etc. , confirmation of the mounting position from below, and temporary fixing near the hanging position are possible, and during this time, each work such as attaching the main body to the hanging rod member, aligning the equipment, pushing up, etc., can be done by one worker. Since it can be carried out independently, it simplifies and speeds up the support work at the site, and it can be carried out safely.It is also inexpensive because it has a simple structure, is easy to handle, and can be reused. This has extremely beneficial effects in practical terms.
