The present invention is composed of a double-layered structure of the lower and upper racks to improve the efficiency and space utilization of goods storage, as well as to improve the support safety and safety of use of the scaffolding member, and to improve the convenience and safety of use by making the upper rack part convenient. It is about a double-layered mobile rack that can be ordered.

1 to 6 illustrate an embodiment of a multilayer mobile rack according to the present invention for this purpose.

As illustrated in the drawings, a multilayer mobile rack according to an embodiment of the present invention may include a moving rack 100, a fixed rack 300, and a scaffold member 500.

The moving rack 100 may be formed of at least two or more, and the fixed rack 300 may be installed in a pair on the left and right of the moving rack 100.

A pair of fixed racks 300 may be spaced from each other to the left and right to be fixedly installed on the ground, and a plurality of movable racks 100 are installed to be movable left and right between a pair of fixed racks 300, thereby They can be close or spaced apart from each other.

The scaffold member 500 passes through the plurality of movable racks 100 and extends left and right, and both ends thereof may be coupled and supported by a pair of fixed racks 300.

Hereinafter, looking at the configuration of the moving rack 100, the fixed rack 300, and the scaffolding member 500 in detail, first, as illustrated in FIGS. 2 and 3, the moving rack 100 is a lower rack part 110 And, it may include an upper rack portion 130, a connection member 150, and a support member 170.

The lower rack unit 110 may be installed on the ground, and the upper rack unit 130 may be installed at a predetermined interval on the upper side of the lower rack unit 110.

The lower rack part 110 and the upper rack part 130 may each have a rectangular box shape supported by a plurality of vertical frames 111 and 131, and therein, between the vertical frames 111 and 131 to allow storage of goods. A plurality of shelves can be installed in multiple stages.

As a driving means for moving the lower rack part 110, it is possible to adopt various configurations previously disclosed without any particular limitation, and any one of a manual type providing movement force by turning a handle and an electric type providing movement force by a driving motor Can be

The connection member 150 may interconnect the lower rack unit 110 and the upper rack unit 130 between the lower rack unit 110 and the upper rack unit 130.

The upper rack unit 130 may be connected to the lower rack unit 110 in a state spaced apart from the lower rack unit 110 to the upper side of the lower rack unit 110 through the connection member 150, and accordingly, the lower rack unit 110 and the upper rack unit 130 A certain space may be created between the heights of the connecting member 150.

The connecting member 150 may be formed of a plurality of pieces arranged to be spaced apart from each other at a predetermined interval in the front and rear between the lower rack unit 110 and the upper rack unit 130.

The plurality of connection members 150 may be disposed to correspond to the positions of the vertical frames 111 and 131 of the lower rack unit 110 and the upper rack unit 130, so that the upper and lower ends may be connected to the vertical frames 111 and 131, respectively.

The plurality of connection members 150 may have a relatively thinner thickness than the vertical frames 111 and 131 so that the spacing between the scaffold members 500 to be described later passing through therebetween is minimized.

The connecting member 150 is an independent element, and the upper and lower ends may be connected to the vertical frames 111 and 131 by welding, etc., but the vertical frame 111 of the lower rack and the vertical frame 131 of the upper rack 130 are unitary. While extending to the middle portion may be configured to perform the function of the connecting member 150.

The support member 170 is installed on the connection member 150 and may support and support a scaffold member 500 to be described later passing between the connection members 150.

As illustrated in FIG. 5, the support member 170 may include a support bar body 171 and a rolling tube body 173.

The support bar body 171 is formed in a circular bar shape, and can be extended back and forth through a plurality of connecting members 150 arranged at regular intervals, and both ends of the extended support bar body 170 are at the front and rear ends. It may be coupled to and fixed to the connection member 150.

The support rod body 171 may be formed of a plurality of horizontally installed support rod bodies 171 spaced apart from each other at regular intervals, and three support rod bodies 171 are illustrated in the drawings as an example.

The rolling tube body 173 may be extrapolated to the support rod body 171 fixed to the connection member 150.

The rolling tube body 173 has the shape of a circular tube, and thus can be freely rotated in a state that is extrapolated to the support bar body 171 having a circular bar shape.

A slip surface 175 capable of sliding may be formed on the inner circumferential surface of the rolling tube body 173 to minimize friction with the outer circumferential surface of the support bar body 171 during rotation.

The rolling tube body 173 may be formed of a plurality of extrapolated to the support rod body 171 between the connection members 150 so as not to interfere with the connection member 150.

The rolling tube body 173 is in contact with the bottom surface of the scaffold member 500 to be described later to provide support to the scaffold member 500, and when the moving rack 100 moves left and right, the scaffold is rotated along the bottom of the scaffold member 500 It is possible to provide a continuous support force to the member 500.

Next, the fixed rack 300 may include a lower rack part 310, an upper rack part 330, a connection member 350, and a footrest use detection member 370.

Similar to the above-described moving rack 100, the lower rack portion 310 of the fixed rack 300 is also installed on the ground, and the upper rack portion 330 may be installed at a predetermined interval above the lower rack portion 310, , The lower rack portion 310 and the upper rack portion 330 may each have a rectangular box shape and may store articles therein.

However, since the fixed rack 300 has a fixed position, unlike the movable rack 100, the lower rack unit 310 is not provided with a balance unit and a driving means.

The connecting member 350 is disposed between the lower rack portion 310 and the upper rack portion 330 of the fixed rack 300 in the same manner as the connecting member 150 of the moving rack 100, and is disposed between the lower rack portion 310 and the upper rack portion. The rack unit 330 may be interconnected.

The scaffolding detection member 370 is installed on the upper surface of the lower rack part 310 between the connecting members 350 to detect whether the scaffolding member 500 to be described later is used.

That is, the scaffolding use detection member 370 may detect whether a user is on the scaffolding member 500 to generate a detection signal for the use of the scaffolding member 500.

As illustrated in FIG. 5, the scaffolding detection member 370 has a support rod 371 protruding upward from the case and coupled to the bottom of the end of the scaffolding member 500, and the user on the scaffolding member 500 An elastic body 373 that elastically supports the support rod 371 so that the support rod 371 is pressed down when the support rod 371 is raised, and a contact terminal 375 that generates a sensing signal by selectively contacting only when the support rod 371 is lowered. It may include.

At this time, the distance d that is lowered when the support rod 371 is pressed can be designed as short as about 1 to 3 cm, through which the user can hardly feel that it descends when standing on the scaffold member 500. You can prevent it.

In addition, the elastic body 373 supports the weight of the scaffold member 500, but when the user rises on the scaffold member 500 and increases the weight by the user's weight, the support rod 371 has an elastic force sufficient to be pressed. I can. For example, when a weight of about 50 kg or more, which is about the minimum weight of one user, is added to the scaffolding member 500, an elastic body 373 to which the support rod 371 can be pressed may be used.

In this configuration, the support rod 371 is selectively pressed and lowered according to the presence of a user on the scaffold member 500, thereby generating a detection signal for the use of the scaffold member 500.

That is, as illustrated in (a) of FIG. 5, in a normal state, the support rod 371 is raised and supported by the elastic body 373 (at this time, the contact terminals 375 are spaced apart from each other). , As illustrated in (b) of FIG. 5, when the user rises above the scaffolding member 500 for loading and unloading items in the upper rack, the support rod 371 is pressed and the contact terminal 375 comes into contact, thereby generating a sensing signal. I can.

The detection signal may be continuously generated until the user completes use and leaves the scaffold member 500.

Using such a detection signal, the user of the lower rack unit 110 can visually or audibly recognize that the user of the upper rack unit 130 is present. For example, a separate warning light or sound output means is installed on the lower rack unit 110 It may be configured to turn on a warning light or output a warning sound according to a detection signal output from the footrest use detection member 370.

Next, the scaffolding member 500 has a shape of a plate that extends long to the left and right, and may support and support a user standing on the upper rack unit 130 so as to easily store and release articles.

The scaffolding member 500 penetrates the moving rack 100 through a space between the lower rack unit 110 and the upper rack unit 130, that is, the space between the connection members 150 and extends left and right. The portion penetrating the moving rack 100 may be supported by the lower support member 170.

In addition, both ends of the scaffold member 500 extending left and right may be coupled and supported by a pair of fixing racks 300.

At this time, the left and right ends of the scaffolding member 500 are supported and coupled to the above-described scaffolding detection member 370, so that when the user stands on the scaffolding member 500, the support rod 371 of the scaffolding sensing member 370 ) Can be lowered as it is pressed.

Therefore, the scaffolding member 500 may be installed so as not to be in close contact with the support member 170 installed in the moving rack 100 and spaced apart from the support member 170 to the upper side, and the scaffolding detection member 370 is pressed. It may be lowered according to the load so as to be selectively supported by the support member 170.

That is, as illustrated in (a) of FIG. 5, the scaffold member 500 is installed so that the bottom surface is spaced apart from the upper surface of the support member 170 by a descending distance (d), so that the user on the scaffold member 500 If there is no, it is spaced a certain distance (d) upward from the support member 170, and then, as illustrated in (b) of FIG. 5, the user rises above the scaffold member 500 so that the sensing member 370 When the support rod 371 is pressed, it is lowered by the distance d and comes into contact with the support member 170 to receive the support of the support member 170.

For example, if the support rod 371 of the scaffolding detection member 370 is designed to be lowered by pressing 1cm, the scaffolding member 500 is installed to pass 1cm apart on the support member 170, and the user passes the scaffolding member 500 ) As it rises above, it is lowered by 1cm to be supported by being in contact with the support member 170.

When not used in this way, since the scaffolding member 500 is spaced apart from the support member 170 by a certain distance and passes through the moving rack 100 without any contact, the moving rack 100 is used only to use the lower rack portion 110. When moving, more smooth movement may be possible.

On the other hand, in the above configuration, as illustrated in the drawings, the lower rack portions 110 and 310 and the upper rack portions 130 and 330, respectively, in which goods are stored and unloaded, may have different sizes, especially in the front and rear directions. As for the length of, the upper rack portions 130 and 330 may be formed relatively short compared to the lower rack portions 110 and 310.

In addition, guard frames 190 and 390 extending upwardly to protrude a certain height may be formed at the front end of the upper surface of the lower rack portions 110 and 310, and a guard rod 191 may be installed on the guard frames 190 and 390. I can.

The guard frames 190 and 390 may be separately coupled and installed at the front end of the upper surface of the lower rack portions 110 and 310 through welding, or may be integrally formed with the front frame 113 by extending the front frame 113 upward to a certain height. have.

The guard rod 191 may be installed to be fixed to the guard frame 390 of the fixed rack 300 while extending to the left and right through the guard frame 190 of the moving rack 100.

The guard rods 191 may be formed in a plurality of vertically spaced apart from each other, and three guard rods 191 are illustrated in the drawings.

When the front and rear lengths of the upper rack portions 130 and 330 are relatively short compared to the front and rear lengths of the lower rack portions 110 and 310 in this way, and the guard frames 190 and 390 are formed at the upper front end of the lower rack portions 110 and 310, As illustrated in FIGS. 3 and 4, between the front ends of the upper rack parts 130 and 330 and the guard frames 190 and 390, a side passage through which a user can pass in the left and right directions by a width corresponding to the difference in length ( S) can be formed.

Therefore, as illustrated in FIG. 6, the user can freely move the goods in and out of the upper rack parts 130 and 330 while moving left and right along the side passageway S, and the guard frame 190, Since fall is prevented by 390) and the guard rod 191, safe passage is possible.

The difference in length in the front and rear directions between the lower rack parts 110 and 310 and the upper rack parts 130 and 330 will be as long as the user can pass without unreasonableness. For example, the upper rack parts 130 and 330 compared to the lower rack parts 110 and 310 ) May be formed relatively short as long as corresponding to the arrangement interval of the connecting members 150 and 350.

Meanwhile, as illustrated in FIG. 1, the present invention may further include a stair frame 700 installed on the side of at least one of the pair of fixed racks 300.

The stair frame 700 may be installed on the side of the fixed rack 300 while having a stair shape, and a user can easily and safely climb or descend to the scaffolding member 500 through the stair frame 700.

The multilayer mobile rack of the present invention having the above configuration can efficiently store articles while moving the plurality of moving racks 100 left and right, like a typical mobile rack, and in particular, the lower rack unit 110 and the upper rack unit It is composed of a multi-layered structure of 130 and expands the storage space, thereby maximizing storage efficiency.

In addition, while passing along the footrest member 500 installed between the lower rack portion 110 and the upper rack portion 130, goods can be easily put in and out of the upper rack portion 130, and the footrest member 500 extends back and forth. By being supported by the support member 170 of the, it receives a more solid support force, so that stable use for a long time is possible.

In addition, when there is a user in the scaffolding member 500 in order to store and unload items in the upper rack unit 130, it is possible to detect this so that the user of the lower rack unit 110 can easily recognize it. It is possible to minimize the risk of a user's safety accidents such as collisions or jamming due to movement.

In addition, since a side passageway (S) is formed in front of the upper rack unit 130 that the user can safely pass in the left and right directions without the risk of falling, the user can freely pass between the upper racks 130, making entry and exit work safe and convenient. Can be done.

As described above, the present invention basically improves the efficiency of storage of goods and space utilization through a multilayer structure of the lower and upper racks, and further improves the support safety and safety of use of the scaffolding member and makes the upper rack part convenient to use. It can be seen that both convenience and safety can be improved.
