Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a mobile rack in a rack system for storing paintings, etc. in an art museum or museum.

``Prior art'' As storage equipment for paintings, etc., a large number of movable racks suspended from ceiling rails are arranged side by side in a storage room, and when necessary, any one of these parallel racks can be moved horizontally. Rack systems are known that allow storage items to be hung and removed by pulling them out.

The mobile racks in this type of rack system usually use large panels with a width of 4 m and a height of around 2 m, but in consideration of convenience in processing and transportation, several small panels are combined. It consists of Furthermore, rollers to be attached to the rails are attached to the upper frame of the assembled large panel.

``Problem that the invention aims to solve'' By the way, considering the state of use of this kind of rack, if it shakes sideways when pulling out or hanging, it will not only be difficult to work, but also cause the stored items on the rack to come into contact with each other. There is a risk of damage due to such things. Therefore, as a means for preventing rolling, it is necessary to use parallel rails to engage the rollers, and to construct the rails and rollers tightly enough to prevent rattling.

However, it is extremely difficult to achieve both a tight structure to prevent rolling and smooth movement of long objects on rails, and it is especially difficult to construct large long objects by assembling several unit structures. In such a case, it is difficult to maintain straightness in the assembly portion, which is the biggest problem with conventional mobile racks of this type.

Therefore, the object of the present invention is to develop a device configuration that can achieve both smooth movement and a roll prevention function in this kind of picture rack.

"Means for Solving the Problem" For this purpose, in the present invention, two mesh panels are attached to both sides of the surrounding frame with a gap equal to the thickness of the frame to form a unit structure. A large rack is constructed by connecting several structural parts in rows. Then, a long piece of metal having a U-shaped cross section that extends over the entire upper frame of the connected unit structure is attached to the upper part of the rack so as to cover the upper frame. A mounting roller for mounting on the rail is arranged on this long hardware.

"Function" The mesh panels attached to both walls of the surrounding frame are
It is possible to freely hang paintings on both sides without restricting the hanging position of the paintings or the like.

The vertical frames of the unit components are butted against each other, and several parts of these parts are integrated by connecting means such as bolting.

The long hardware having a U-shaped cross section and fixed over the upper frame of the assembled large rack forcibly corrects the bending of the assembled unit components when they are connected.
By the above means, a large rack with good straightness can be guided by the rails and moved smoothly and with little lateral movement.

Next, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

``Embodiment'' Fig. 1 is a plan view showing an embodiment of the present invention, and Fig. 2 is a side view thereof. , a horizontal plate 3 is attached, and rollers 4,
4 are arranged respectively, and the rollers 4, 4 are respectively engaged with two rails 6, 6 arranged parallel to the ceiling 5, so that the rack 1 can be freely moved along the rails 6, 6. be.

FIG. 3 is a cross-sectional view of the main parts of the present invention, in which mesh panels 8a and 8b are arranged on the upper frame 7 of the unit component 2a, with gaps equal to the thickness of the frame on both sides of the surrounding frame including the frame 7. are welded together.

Further, this upper frame 7 has respective upper frames 7, which are extended by butting against the unit constituent parts 2a to 2d.
A long object 9 having a U-shaped cross section is fitted over the entire area of the upper frames 7, 7... and the elongated metal object 9 are attached together by bolting or the like. Further, a horizontal plate 3 is integrally welded to the upper surface of the elongated metal object 9, and the rollers 4, 4 are arranged on both side edges of the plate 3 at appropriate intervals. A triangular reinforcing plate 10 is provided between the lower surface of the horizontal plate 3 of the roller placement part and the side of the elongated hardware 9.

According to the embodiment having such a configuration, the unit components 2a to 2d are sequentially assembled by butting their side frames against each other, and at that time, the bolts are temporarily tightened, and the length is Assembling is carried out by passing the shaku hardware 9 over the upper frames 7, 7, etc., and fully tightening the unit components 2a to 2d while integrating them by tightening bolts. The large rack 1 is regulated by the elongated metal fittings 9 and assembled in a straight line without bending in the longitudinal direction (lateral direction).

As a result, the rack 1 can be smoothly moved along the rails 6 by respectively engaging the rollers 4, 4 provided on the elongated hardware 9 with the parallel rails 6, 6 arranged in advance on the ceiling 5. I can do it.
Furthermore, since the rack 1 itself has good linearity, even if the rail 6 and roller 4 are tightly engaged with each other with little play, smooth movement is possible during the movement. , it is possible to prevent rack 1 from rolling.

Incidentally, in order to ensure more reliable stability of the rack 1, it is effective to arrange the long hardware 9 also on the lower frame side of the rack 1.

``Effect of the invention'' As described above, in the rack of the present invention, when a large rack is constructed by assembling several unit components of a predetermined size, the entire area of the upper frame of each assembled unit component is By attaching a long metal piece with a U-shaped cross section to fit with this, it is possible to correct the distortion of the unit component itself and the bending at the assembly part, and moreover, this long metal piece By arranging the rollers for mounting the rails on the long hardware, the rails and rollers have good linear fit, and the smooth rolling motion of the rollers allows for easy movement. Close engagement between the equal rail and the rollers is also possible, which is extremely effective in preventing the rack from rolling.

Furthermore, since the rack of the present invention has a double-sided mesh panel structure, it is possible to increase the storage efficiency by using both sides, and it also has good flatness as a unit component, and has strength that does not easily cause distortion even after long-term use. The rack of the present invention is extremely useful in practical use as a mobile painting rack of this type.
