Description

The present invention relates to a suspension stand that is used, for example, to suspend and install air conditioning equipment from the ceiling of a building.

For example, as shown in FIG. 34, a suspension stand 102 for suspending an air conditioner 101 or the like from the ceiling 100 of a building is known.

However, with conventional hanging racks, if the weight of the air conditioning equipment 101 is heavy or if the hanging length is long, it is necessary to use a steel frame for hanging support.

However, when using steel hoists in this way, it is difficult to adjust the position of heavy air conditioning equipment, and fine adjustment of the equipment position is not possible. In other words, there is a problem that new hoisting holes must be drilled in the steel hoists to adjust the position, and it is necessary to install new sink members and attach members for position adjustment. In addition, since architectural beams and other facilities interfere with the equipment stand, a steel hoist must be manufactured and attached individually for each heavy air conditioning unit, which poses the problem of time-consuming drawings for and manufacturing the stand.

The present invention takes into consideration the above-mentioned problems with the conventional technology and aims to provide a hanging stand that allows easy position adjustment when hanging air conditioning equipment or the like.

The embodiment of the present invention will be described in detail with reference to the drawings.

[First embodiment]
FIG. 1 is a perspective view seen from below showing an example of a suspension stand according to a first embodiment of the present invention.

In Figures 1 to 12, 1 is a first frame member, 2 is a second frame member, 3 is other frame members, 4 is air conditioning equipment, 5 is other equipment installed in the suspension rack A, and 6a is a first rod-shaped member.

The hanging stand A is a stand that suspends the air conditioning equipment 4 and installs it on the ceiling or the like. Here, the hanging stand A in this embodiment is composed of multiple frame members 1, 2, and 3, and the first frame member 1 is a member that is arranged in the horizontal direction. Also, as described later, the second frame member 2 is also a member that is arranged in the horizontal direction.

The first frame member 1 has a first slit portion 1a formed vertically along its longitudinal direction. That is, the first frame member 1 is composed of two plates 1b, 1b with an L-shaped cross section arranged opposite each other, with the upper corresponding upper surfaces 1b1, 1b1 arranged horizontally and the lower corresponding lower surfaces 1b2, 1b2 arranged vertically, with the above-mentioned first slit portion 1a being formed in the gap between the lower surfaces 1b2, 1b2.

Furthermore, the first locking mechanism 6 slidably locks the air conditioning equipment 4 to the first frame member 1.

That is, the first locking mechanism 6 has a first rod-shaped member 6a and a first locking member 6b, the first rod-shaped member 6a penetrates the first slit portion 1a from top to bottom in a state in which it can slide horizontally, and the first locking member 6b is attached to the upper part of the first rod-shaped member 6a and locks the first rod-shaped member 6a so that it does not fall out of the first slit portion 1a.

Here, the first rod-shaped member 6a is, for example, a long metal rod, and the first locking member 6b is, for example, a nut that is fixed to the top of the first rod-shaped member 6a and has a width larger than the first slit portion 1a. This locks the first rod-shaped member 6a so that it does not fall out of the first slit portion 1a.

The air conditioner 4 is suspended from the lower end of the first rod-shaped member 6a.

With this configuration, the horizontal position of the air conditioning device 4 can be adjusted by moving the first rod-shaped member 6a along the first slit portion 1a.

Next, after the predetermined position adjustment is completed, a fixing member 7 is provided so that the first rod-shaped member 6a remains firmly in place. That is, this fixing member 7 is composed of a U-shaped bracket 7a, a first nut 7b, and a first screw 7c.

The lower parts of the two first lower surfaces 1b2 of the first frame member 1 are fitted inside the U-shaped cross-section bracket 7a, and the first rod-shaped member 6a penetrates the first bottom surface 7a1 of the U-shaped cross-section bracket 7a, and the first nut 7b screwed onto the first rod-shaped member 6a on the underside 7a2 side of the first bottom surface 7a1 prevents the U-shaped cross-section bracket 7a from falling.

Furthermore, of the two first vertical surfaces 7a4 of the U-shaped cross-section bracket 7a, at least one of the first vertical surfaces 7a4 has a first hole 7a3 drilled therein, and a first screw 7c is screwed into the first hole 7a3 and its tip abuts against the first lower surface 1b2 of the L-shaped cross-section plate 1b, thereby fixing the U-shaped cross-section bracket 7a and the first rod-shaped member 6a to the first lower surface 1b2 of the first L-shaped cross-section plate 1b.

When only one of the two first vertical surfaces 7a4 of the U-shaped cross-section bracket 7a is fixed with the first screw 7c, the other first vertical surface 7a4 that is not screwed is fixed in surface contact with the first lower surface 1b2 of the first L-shaped cross-section plate 1b, so the fixing effect is great. Of course, both first vertical surfaces 7a4 may also be fixed from both sides with the first screw 7c.

In this way, the first rod-shaped member 6a and the suspended air conditioner 4 are firmly fixed in the desired position on the first frame member 1. It is stable and will not shift position even in the event of an earthquake or other disaster.

Next, the second frame member 2 mentioned above will be described. That is, among the multiple frame members, another second frame member 2 is arranged horizontally. As shown in FIG. 1, this second frame member 2 is fixed horizontally to the lower end of the other frame member 3. Note that the first frame member 1 is arranged perpendicularly to the lower side of the second frame member 2.

This second frame member 2 has a second slit portion formed vertically along its longitudinal direction.

That is, the second frame member 2 is composed of two second L-shaped cross-section plates 2b arranged opposite each other, the corresponding second lower half surfaces 2b2, 2b2 on the lower side are arranged horizontally, the corresponding second upper half surfaces 2b1, 2b1 on the upper side are arranged vertically, and the second slit portion 2a is formed in the gap between the second upper half surfaces 2b1, 2b1.

The second rod-shaped member 8a constituting the second locking mechanism 8 penetrates the second slit portion 2a in the vertical direction while being horizontally slidable (see Figures 10 and 11). In this first embodiment, two second rod-shaped members 8a penetrate in parallel.

Because of this configuration, the second rod-shaped member 8a can slide through the second slit portion 2a, allowing for free position adjustment.

Furthermore, the upper parts of the two second upper surfaces 2b1 of the second frame member 2 are fitted inside the inverted U-shaped cross-section bracket 9, and the two second rod-shaped members 8a penetrate upward through the second bottom surface 9a of the inverted U-shaped cross-section bracket 9, and two locking members 8b, 8b, such as nuts, that constitute the second locking mechanism 8 are screwed onto the upper ends of the penetrating second rod-shaped members 8a.

The second rod-shaped member 8a of the second locking mechanism 8 described above may be composed of a single screw. That is, the head, which is larger than the gap of the second slit portion 2a, corresponds to the locking member 8b, and the body and threaded portion correspond to the second rod-shaped member 8a.

At least one of the two second vertical surfaces 9b of the inverted U-shaped cross-section bracket 9 has a second hole 9c drilled in it, and a second screw 10 is screwed into the second hole 9c and its tip abuts against the second upper surface 2b1 of the second L-shaped cross-section plate 2b, thereby fixing the inverted U-shaped cross-section bracket 9 and the second rod-shaped member 8a to the second upper surface 2b1 of the second L-shaped cross-section plate 2b.

In addition, in the case where the second hole 9c is drilled in only one of the two second vertical surfaces 9b of the inverted U-shaped cross-section bracket 9 and the second screw 10 is screwed into that second hole 9c, the other second vertical surface 9b that is not screwed is fixed in surface contact with the second upper surface 2b1 of the second L-shaped cross-section plate 2b, as in the case of the first frame member 1, and the fixing effect is great. Of course, both second vertical surfaces 9b may be fixed from both sides with the second screw 10.

Furthermore, the first frame member 1 is held by the lower part of the second rod-shaped member 8a. In the illustrated embodiment, the lower part of the second rod-shaped member 8a penetrates downward through the first upper surface 1b1 of the L-shaped cross-section plate 1b of the first frame member 1, and is fixed by a lower nut 11 screwed onto the lower end. In other words, the first frame member 1 is connected to the lower side of the second frame member 2.

As a result, as described above, the second rod-shaped member 8a can slide horizontally through the second slit portion 2a, and the first frame member 1 fixed to the lower end of the second rod-shaped member 8a can also slide horizontally together.

In this way, when adjusting the position of the air conditioning equipment 4, the first rod-shaped member 6a is moved to the desired position along the first frame member 1, and then the position can be adjusted in all directions by moving the first frame member 1 along the second frame member 2 to adjust the position perpendicular to that direction.

Furthermore, as shown in Figs. 4 to 6, the equipment 5 is mounted on two parallel L-shaped frames 51, 51 spaced a predetermined distance from each other using long bolts 51d. These two L-shaped frames 51, 51 are connected to the first frame members 1, 1 so as to be slidable perpendicularly.

That is, a bolt 51b is attached to each of the horizontal sides 51a of the L-shaped cross section frame 51, and the bolt heads are designed to prevent the bolts from falling out downward, and the body and threads of the bolts 51b penetrate downward between the first slits 1a of the first frame member 1 so as to be slidable horizontally. This makes it easy to adjust the position.

Furthermore, as shown in Figs. 6 and 7, a nut 51c is screwed onto the lower end of the bolt 51b, and in preparation for an earthquake or the like, the nut 51c is firmly abutted against the lower edge of the first slit portion 1a, thereby firmly fixing the L-shaped cross-section frames 51, 51 to the first frame member 1.

In the above-mentioned example of the suspension rack, it is desirable to use both aluminum section steel and SS section steel as the material for each frame member in FIG. 1. Here, 20 is a frame member made of SS section steel, and the remaining frame members are made of aluminum section steel.

This type of embodiment has the following advantages. Although the aluminum section steel specification allows for weight reduction, aluminum is vulnerable to alkali and may corrode if installed directly on the ceiling slab surface. This is because concrete mortar is highly alkaline and dissolves and corrodes aluminum section steel. Therefore, it is desirable to use stainless steel section steel for the slab surface and direct installation locations as a corrosion prevention measure.

[Second embodiment]
13 to 18 show the second embodiment. In the first embodiment, as shown in Fig. 8 and Fig. 12, two second rod members 8a and two second locking members 8b are used in the second locking mechanism 8, and the lower end of each of the second rod members 8a penetrates downward through the first upper surface 1b1, 1b1 of the L-shaped cross-section plate 1b of the first frame member 1, respectively.

In contrast, the second embodiment differs from the first embodiment in that the second locking mechanism 8 is composed of one second rod-shaped member 8a and one second locking member 8b.

That is, the second rod-shaped member 8a penetrates downward through approximately the center of the bottom surface 9a of the inverted U-shaped cross-section bracket 9, penetrates the second slit portion 2a, and further penetrates downward between the first slit portions 1a of the first frame member 1, and at the lower edge of the first slit portion 1a, penetrates the third bottom surface 12a of the U-shaped cross-section bracket 12 and is screwed into the lower nut 11.

As with the U-shaped cross-section bracket 7a, this U-shaped cross-section bracket 12 is fixed to the first lower surface 1b2 of the L-shaped cross-section plate of the first frame member 1 by a third screw screwed into a third hole 12c drilled in the third vertical surface portion 12b.

In the first embodiment, the second rod-shaped member 8a penetrates the first upper surface 1b1, 1b1 of the L-shaped cross-section plate 1b of the first frame member 1, so the first frame member 1 cannot slide perpendicularly to the second frame member 2. However, in the second embodiment, the second rod-shaped member 8a penetrates downward between the first slits 1a, so the first frame member 1 can not only slide along the second frame member 2, but can also slide perpendicularly to the second frame member 2, which has the advantage of increasing the options for position adjustment.

As mentioned above, the first rod-shaped member 6a can be slid along the first frame member 1.

In each of the above embodiments, the metal fittings that hold the slits are not limited to brackets with a U-shaped cross section, but can also be metal fittings with a U-shaped or L-shaped cross section.

Also, if you just want to prevent the nut from falling out of the slit, you can use a washer that is wider than the slit in combination with the nut.

Figures 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, and 32 are respectively a front view, right side view, left side view, rear view, plan view, bottom view, view looking up to the left (from the front side), view looking up to the right (from the front side), view looking up to the left (from the rear side), view looking up to the right (from the rear side), view looking down to the left (from the front side), view looking down to the right (from the front side), view looking down to the left (from the rear side), and view looking down to the right (from the rear side) of the suspension rack in the second embodiment of the present invention.

Next, Figure 33 shows an application example where the position can be adjusted using the slits mentioned above.

Here, at the upper position, the first frame member 1 and the second frame member 2 are connected in an orthogonal arrangement with the structure described above. The lower end 6a1 of the first rod-shaped member 6a passes through the slit 14a of the first lower frame member 14 and is secured by a nut or the like as described above. In this way, the first rod-shaped member 6a is able to slide in the direction of the slit of the first frame member 1.

18 is an intermediate frame that is supported at a mid-position of the first rod-shaped member 6a, and the position of the intermediate frame 18 can be adjusted as the first rod-shaped member 6a slides.

Furthermore, the end of the first lower frame 14 is slidably connected to the second lower frame 15, which is the fixed frame of the hanging stand A, by the structure 16 described above (nuts and brackets are not shown). That is, the first lower frame 14 slides in the direction of the slits of the second lower frame 15 and also in a direction perpendicular to the second lower frame 15 in response to the first frame member 1 sliding in the direction of the slits of the second frame member 2 and sliding in a direction perpendicular to the second frame member 2.

In this way, the position of the first lower frame 14 can be easily adjusted, providing a wide range of options.

The suspension stand A in Figure 33 has adjustable frames arranged vertically and horizontally as described above, so the duct 16 and electrical rack support 17 can also be arranged in various ways as shown in the figure.

The suspension stand of the present invention provides a suspension stand that can be easily adjusted for suspending air conditioners and other equipment, making it useful for suspending heavy objects such as air conditioners from the ceiling.
