Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a movable shelf device in which a plurality of movable shelves are arranged so that they can be assembled and separated. Regarding shelf devices.

(Conventional technology) In order to efficiently utilize indoor space, a plurality of movable shelves that can move perpendicular to the frontage surface are arranged so that they can be assembled and separated, and the movable shelves are moved by electric or manual power to There is a movable shelf device in which a passage for loading and unloading articles is formed only in the front of the movable shelf. Then, if all the movable shelves are assembled in such a movable shelf device and at least the outer movable shelf is restrained and locked so that it cannot be moved, no one other than the owner of the key can take out the items stored in the movable shelf. It is known that this increases the anti-theft effect.

(Problems to be solved by the invention) According to the conventional movable shelf device having a locking device,
If an earthquake occurs while the locking device is locked,
It has become clear that the danger is greater than if the door is left unlocked. That is, in a movable shelf that has a locking device that locks the drive mechanism of the movable shelf inoperable and locks it in the locked state, when the movable shelf is locked with the locking device, the energy of the earthquake can damage the locking device. The signal is transmitted directly to the movable shelf through the cable, causing the movable shelf to shake with the ground or building.
The running wheels slide on the smooth rails or floor, and there is a risk that the movable shelves will collide with each other, causing the worker to be caught between the movable shelves. In addition, movable shelves that have a locking device that locks the movable shelf in a locked state by engaging a bolt lowered from the movable shelf with a hole formed in the floor or rail, etc., lock the movable shelf in the locked state. The swayed movable shelf attempts to move along the rails, etc., while the locking device attempts to lock the movable shelf so that it cannot be moved, making the movable shelf extremely susceptible to falling over and causing damage to workers in the aisle. This is an extremely dangerous situation.

On the other hand, even if an earthquake occurs when the lock is unlocked, most of the shaking of the ground or floor due to the earthquake will be absorbed by the running wheels rotating on the spot, and the seismic energy will be transferred to the movable shelf. It becomes seismically isolated without being transmitted to the main body, and each movable shelf only moves synchronously with respect to vibration within a limited range, ensuring the safety of workers in the passage.

This invention was made in view of these points,
By making it possible to lock multiple movable shelves together so that they cannot be moved and to lock them in the locked state, the anti-theft effect is enhanced, and even if an earthquake occurs while the movable shelves are locked, the movable shelves will not slide unnecessarily. It is an object of the present invention to provide a locking device for a movable shelf that can prevent objects from falling over, ensure the safety of workers in a work passage, and prevent items stored in the movable shelf from falling. purpose.

(Means for solving the problem) The present invention enables the mobile shelf to be moved even when it is locked.
The movable shelf is characterized in that the movable shelf can be moved within a range of 30 mm or more, which is a range in which a space between the shelves is narrower than the space in which a human body can enter.

(Function) If an earthquake occurs when the movable shelves are grouped together and locked so that they cannot be moved, the movable shelves will move relatively back and forth in synchronization with the shaking of the earthquake within a range of 30 mm or more, and during this time the traveling wheels will rotate back and forth. By simply doing so, the seismic energy is not transmitted to the movable shelf itself and the movable shelf becomes seismically isolated, and the movable shelf will not slide or fall unnecessarily. In addition, the range in which the movable shelves can be moved in a locked state is the range where the space between the shelves is narrower than the space between which a human body can enter, so items stored on the movable shelves cannot be taken out. That is almost impossible.

(Example) Hereinafter, an example of a locking device for a movable shelf device according to the present invention will be described with reference to the drawings.

In Fig. 1, a guide rail 8 is laid on the floor of a building, etc., and a shelf 3 is fixedly installed on this guide rail 8, and a plurality of movable shelves 1 and 2 are installed on the entrance surface of the guide rail 8. The vehicle is arranged so that it can run in a direction perpendicular to the road (left and right in the figure). Each of the movable shelves 1 and 2 can run along a guide rail 8 by means of running wheels 7 provided at the bottom thereof, and the movable shelves 1 and 2 can be assembled on the fixed shelf 3 side, and articles can be placed between the desired shelves. It can be separated to form a working passage for loading and unloading. A rotation operation handle 5 is provided on the side surface of each movable shelf 1, 2, and the rotational force of the handle 5 is transmitted to the running wheels 7 via a deceleration transmission mechanism (not shown) to rotationally drive the running wheels 7. The movable shelves 1 and 2 are made to travel. A lock operation knob 16 is provided at the center of rotation of the handle 5 of each movable shelf 1, 2 to prevent each movable shelf 1, 2 from moving unnecessarily. In FIG. 1, a lock 4 of a locking device is attached to the side surface of the rightmost movable shelf 1.

As shown in FIG. 2, by inserting a key into the lock 4 and locking it, the bolt 6, which is supported inside the side plate of the movable shelf 1 so as to be movable in the vertical direction along the same side plate, is lowered. The lower end thereof is adapted to lock the movable shelf 1 by engaging with an engagement hole or an engagement protrusion formed on the floor of the building, a guide rail, a rail plate, or the like. However, such locking is
As shown in FIG. 1, the movable shelves 1 and 2 are assembled together.

3 and 4 show an example of the structure of the engaging portion of the bolt 6. As shown in FIG. In FIGS. 3 and 4, the guide rail 8 is laid on the rail plate 21. As shown in FIG.
The rail plate 21 has both side edges bent upward and folded inward, and a guide rail 8 is laid on the inner bottom of the rail plate 21 laid on the floor. A pair of engaging pieces 20 are fixed at a predetermined interval in the gap between the folded portion of the rail plate 21 and the side surface of the guide rail 8. The engagement piece 20 is fixed to the guide rail 8 and the rail plate 21 by means such as welding. When the movable shelves 1 and 2 are assembled and locked with the lock 4 as shown in FIG. 1, the bolt 6 shown in FIG. 2 descends and its lower end enters between the engagement pieces 20. In this state, the movable shelf can only move within the range allowed by the lock 6 between the pair of engagement pieces 20. At this time, the movable range of the movable shelves is set to a range where a space between the movable shelves is narrower than the space between which a human body can fit, and is set to a range of 30 mm or more.

FIG. 9 shows an example of the coupling relationship between the lock 4 and the bolt 6. The lock 4 has a structure similar to that of a well-known cylinder lock, and a tongue piece 4a moves forward and backward from the lower end of the lock 4 by rotating a key inserted into the lock 4. The upper end of the bar 6 is pivotally attached to the tongue piece 4a by a pin 47. The bolt 6 is urged to move downward by a spring 48 applied to the pin 6a.

Now, when the movable shelves are assembled and the key is inserted into the lock 4 of the movable shelf 1 to lock it, the bolt 6 descends and its lower end enters between the two engaging pieces 20, and the movable shelves are locked. 1 is locked. As mentioned above, the movable shelf 1 is movable within a predetermined range in the locked state, but the movable range is a range in which the space between the movable shelves is narrower than the space between which a human body can enter. Therefore, a person cannot enter the space between the movable shelves and cannot take out the articles stored in the movable shelves, so that the anti-theft effect can be maintained. In addition, if an earthquake occurs in a locked state, the movable shelf can move relative to the rail 8 within a range of at least 30 mm, so the running wheels 7 reciprocate back and forth within this range of relative movement, and the earthquake energy is directly absorbed. The information will not be transmitted to the movable shelf, and the movable shelf will not be moved or overturned. This prevents people near the movable shelf from being harmed and stored articles from falling.

The range within which the movable shelf can be moved when locked is:
From the viewpoint of preventing the movable shelf from falling or preventing stored articles from falling, it is desirable that the range be as wide as possible. For example, if the movable range of a movable shelf in a locked state is 50 mm or more, it will be able to prevent it from tipping over and preventing items from falling in most earthquakes. By doing so, it is possible to prevent overturning and objects from falling even in the event of an earthquake with the largest amplitude. of course,
In order to prevent theft, the range in which the movable shelves can be moved in the locked state must be within a range that is narrower than the space between the movable shelves that allows a human body to enter, and this range is the maximum. Limited.

The interlocking relationship between the lock and the bolt is not limited to that shown in Fig. 9; the bolt may be engaged with a tongue that moves forward and backward from the lock body during locking and unlocking operations, and the movement of the tongue can be directly controlled. It may be transmitted to the bolt,
A lock may be provided at the bottom of the movable shelf, and the tongue of the lock may be used as a bar to engage directly with the engagement piece or engagement hole. You can.

The engagement partner of the bolt 6 may be an engagement hole 22 formed in the guide rail 8 as shown in FIG. The engagement hole 22 is elongated in the moving direction of the movable shelf, and the lock 6 can be locked by locking the lock as described above.
When the lower end part is fitted into the engagement hole 22, the movable shelf is movable within a range of 30 mm or more within a range where a space between the shelves is narrower than the space between which a human body can fit. The length of the engagement hole 22 is determined.

The object to which the bolt 6 is engaged may be pins 30 fixed at regular intervals along an arc centered on the axle on the side surface of the running wheel 7, as shown in FIG. When the bolt 6 is inserted between the pins 30, the running wheel 7 can only rotate within the range where the bolt 6 contacts one pin 30 and contacts another pin 30 adjacent to this pin 30. The movable shelf 1 can move within a rotatable range of 7. By setting the movable range of this movable shelf 1 to a range in which the space between the shelves is narrower than the space between which a human body can fit, and is 30 mm or more, the movable range is similar to the above-mentioned embodiment. It has the effect of In addition,
The pin 30 with which the bolt 6 engages may be provided on a separate member from the running wheel 7, and this separate member may be provided coaxially and integrally with the running wheel 7. Furthermore, the running wheels 7 may be either driving wheels or driven wheels.

7 and 8 show still another example of the engagement mechanism of the bolt 6. FIG. This example is substantially the same as that described in Japanese Utility Model Publication No. 53-45791. In FIGS. 7 and 8, the vertical movement of the bolt 6 based on the locking operation is controlled by a bell crank 12 rotatably supported in a vertical plane by the underframe 14 of the movable shelf.
is transmitted to the bolt 11 as a horizontal movement. One end surface of the second bolt 11 faces an engagement hole 7a formed in an arc shape on the side surface of the running wheel 7. The engagement holes 7a are long and formed in an appropriate number along an arc centered on the axis of the wheel 7. When the bolt 6 is lowered by the locking operation, the second bolt 11 moves horizontally due to the rotation of the bell crank 12, and one end of the second bolt 11 enters the engagement hole 7a of the wheel 7. This allows the wheels 7 to rotate only within the range allowed by the engagement holes 7a, and the movable shelf to travel only within this range. The movable range of the movable shelves in this locked state is the range where the space between the shelves is narrower than the space between the shelves where a human body can enter, and the distance between the shelves is 30 mm or more, as in the previous embodiments. Set to range.

Next, a specific example of the lock device provided on each movable shelf 1, 2 will be explained with reference to FIG. This locking device locks the movable shelf at any position to prevent it from moving unnecessarily during normal use. If an earthquake occurs while this locking device is in a state where the movable shelf is locked, the seismic energy is directly transmitted to the movable shelf through the locking device, causing the movable shelf to slide or fall. In the case of a lock device, the lock state is automatically released when an earthquake occurs. This locking device was patented in 1982.
It is the same as that described in the specification and drawings of No. 142620.

In FIG. 10, a tube shaft 18 is rotatably supported via a bearing between a side plate 24 of the movable shelf and an inner panel 26 disposed at an appropriate distance from the side plate 24. The boss portion 15 of the aforementioned rotary operation handle 5 is fitted into and fixed to the outer end of the tube shaft 18 protruding from the side plate 24. A sprocket 19 and a lock plate 25 are fitted and fixed to the tube shaft 18 between a side plate 24 and an inner panel 26. The rotational force of the sprocket 19 due to the rotational operation of the handle 5 is transmitted to the front running wheels via a deceleration transmission mechanism including a chain (not shown).
The lock plate 25 has many notches 25 on the outer peripheral edge of the disc.
It is shaped like an a. A locking member 17 is slidably inserted into the tube shaft 18.
One end of the locking member 17 is the boss portion 1 of the handle 5.
5, and a lock operation knob 16 is fixed to this projecting end. The inner end of the lock member 17 is bent upward at a right angle, and then folded back at a right angle, and this folded end forms the engaging portion 17b.
It is becoming. This engaging portion 17b is connected to the inner panel 26.
It passes through the hole 26a and faces the outer peripheral edge of the lock plate 25. When the lock operation knob 16 is pinched and pulled toward the user, the lock member 17 slides to the left in the figure, and the engaging portion 17b engages with the notch 25a of the lock plate 25. In this state, the tube shaft 18, handle 5, and sprocket 19 cannot rotate.
Furthermore, the speed reduction transmission mechanism connected to the sprocket 19 and the running wheels are locked so that they cannot rotate, and the movable shelf is restrained in place so that it cannot run. When the movable shelf is to be moved, the lock operation knob 16 is pushed in to disengage the engagement portion 17b of the lock member 17 and the lock plate 25, and then the handle 5 is rotated.

A projecting piece 17a is fixed to the upwardly bent portion of the lock member 17. A swinging body 50 is pivotally supported on the inner surface of the inner panel 26 by a shaft 52 so as to be swingable in a vertical plane. The rocking body 50 has a weight 51 at its tip and is normally in a hanging state as shown in the figure, but when the movable shelf is shaken by an earthquake, the rocking body 50 is also rocked about a shaft 52. When the rocking body 50 swings, the protrusion 17a of the locking member 17 is within the swinging range of the protrusion 50a formed on the rocking body 50, and the protrusion 50a pushes the protrusion 17a, thereby locking the lock plate 25. The engagement relationship between the lock member 17 and the lock member 17 is released. Therefore, if an earthquake occurs when a movable shelf is locked so that it cannot be moved using a locking device for loading and unloading items, the lock will be automatically released, preventing the movable shelf from sliding or falling over. This prevents

The embodiment shown in FIG. 1 has a locking device as described in connection with FIG. 10, and also includes a locking device that can lock the movable shelves in a grouped state to prevent the movable shelves from moving. have. The above-mentioned lock device is designed to automatically release the lock state in the event of an earthquake.
In addition, the above-mentioned locking device is designed to be able to move the movable shelves within a range of 30 mm or more in the locked state and within a range where a space is narrower than the space between the shelves where a human body can enter. When an earthquake occurs, the locking device automatically releases the locked state to prevent seismic energy from being directly transmitted to the movable shelf, and then the locking device limits the range in which the movable shelf can move within a certain range. As a result, it is possible to prevent the movable shelf from sliding and falling, and it is also possible to prevent the stored items from being stolen.

The locking device may be such that the locking device is restrained in the locked state by a lock. 11th
What is shown in FIG. 12 is an example. 11th
In FIG. 12, the handle 5, the tube shaft 18,
The lock member 17, sprocket 19, lock operation knob 16, etc. are constructed almost the same as the lock device shown in FIG. 10, and instead of the oscillating body 50 in the example shown in FIG. 10 being omitted, a lock 27 is installed. They differ greatly in that they are Further, the lock plate 2 facing the engaging portion 17b of the lock member 17
As shown in FIG. 12, two engaging protrusions 25b are integrally formed on the outer peripheral edge of 5 at positions opposite to each other with the rotation axis in between. When the lock member 17 is moved to the left in FIG. 11 by pinching the lock operation knob 16, the engaging portion 17b advances onto the passage of the engaging protrusion 25b of the lock plate 25. When the lock 27 is locked in this state, the bolt 28 advances behind the lock member 17 and locks the lock member 17.
prevent it from returning to its original position. In this state, the handle 5 can be rotated back and forth until the engaging portion 17b of the lock member 17 engages with the two engaging protrusions 25b of the lock plate 25, and the movable shelf cannot be moved within that range. I can do it. However, the traveling range of the movable shelves at this time is such that the distance between the two shelves is narrower than the space between which a human body can fit, and the range is 30 mm or more. The interval between the engagement protrusions 25b, the reduction ratio of the reduction transmission mechanism, and other conditions are set.

According to the example in FIGS. 11 and 12, the knob 16
By pulling , the mobile shelf can be locked so that it cannot be moved. However, since the handle 5 is rotatable, although within a limited range, the movable shelf can be moved within a certain range. but,
The movable range is limited to a range where the space between the shelves is narrower than the space a human body can enter, and the function as a locking device is not impaired. It also locks the locking device, and
When the locking device is locked by the lock 27,
The locked state cannot be released, and the movable shelf can only move within the above-mentioned limited range. Even if the movable shelves move within this limited range, it is impossible for a human body to enter between the shelves.
Since stored items cannot be taken out, there is an effect of preventing theft. In addition, if an earthquake occurs in the above-mentioned locked state, the movable shelf can move freely within a range of 30 mm or more, so seismic energy is absorbed while moving back and forth synchronously with the earthquake, causing the movable shelf to slide or Falling over is prevented, and stored articles are also prevented from falling.

Figure 13 shows that when the locking device of the movable shelf device described so far is used, the movable shelf 1 moves within a limited range due to the occurrence of an earthquake, and the space between the movable shelf 1 and the adjacent shelf 2 is The distance b formed in FIG. The maximum distance b is smaller than the distance between the shelves where a human body can fit, and the minimum distance b is 30 mm. If it is within this range, the anti-theft effect will not be impaired as described above, and the movable shelf will not slide or fall unnecessarily due to the earthquake energy absorption effect. As mentioned earlier, from the perspective of seismic energy absorption effect, the interval b should be, for example, 50 mm or more, or even 80 mm.
As mentioned above, the larger the size, the better.

As mentioned above, the fact that the movable shelves can be moved within a limited range in the locked state does not necessarily mean that there will be cases where it is possible to reach through the gaps between the shelves and take out stored items. Therefore, a door may be provided on the side of the frontage surface of each movable shelf to further enhance the anti-theft effect. Figures 14 to 19 show various examples of how such doors can be installed. In the example shown in FIGS. 14 and 15, a hinged door 4 is provided on the side of the frontage surface of each movable shelf 1, 2.
0 is set. When the movable shelves 1 and 2 are assembled and locked, a part of the frontage is closed by a door 40. In this way, even if the user extends his hand through the gap formed between the shelves at regular intervals, his hand will not be able to enter the shelf because it will be blocked by the door 40, making it extremely difficult to take out the stored items. When a work passage of a predetermined width is formed between the shelves to take in and take out articles, the door 40 is opened as necessary to take in and take out the articles. The width of the door 40 may be determined depending on the size of the gap formed between the shelves when the door is locked, the items to be stored, and the like. Furthermore, if important items are stored only on a part of the shelf, a door may be provided to shield only that part.

The format of the door mentioned above is not particularly limited,
For example, it may be a screen door 41 as shown in the example of FIG. 16, or a sliding door 42 as shown in the example of FIG.
Alternatively, a lattice-type door 44 may be used as in the example shown in FIG. 18, or a shutter-type door 45 may be used as in the example in FIG. In addition, tendon type doors, accordion type doors, etc. may also be used. Additionally, the door may be biased in one direction.

A shielding plate may be provided in place of the door. For example, as shown in FIGS. 20 and 21, a mobile shelf 2
A shielding plate 55 may be provided on one side edge of the movable shelf 1, which can shield the one side edge of the movable shelf 1 when adjacent movable shelves 1 approach. The width of the shielding plate 55 is desirably set to such a level that it is impossible to insert a hand into the gap formed between both shelves 1 and 2 in the locked state, or more. Even if it can be inserted, there is no problem as long as the stored article cannot be taken out. The shield plate is installed not only on the side of the handle 5 on which it is installed, but also on the side of the installation side of the handle 5.
As shown by reference numeral 56 in FIG. 21, it may also be provided on the top plate of the movable shelf, thereby further improving the anti-theft effect. Also, the second
As shown by reference numerals 57 and 58 in FIG.
A shielding plate may be provided not only on the front side surface of 1 and 62 but also on the rear side surface. In FIG. 22, the movable shelves 61 and 62 are hand-pulled movable shelves, but they may be handle-type movable shelves or electric movable shelves. A wire mesh or a grid for shielding may be used instead of the shielding plate. When using shielding members, they may be provided separately on both adjacent movable shelves. Furthermore, when a door is provided instead of the shielding plate, the door may be provided on the front side, the back side, and the ceiling of the movable shelf. FIG. 23 shows this example, where 62 is a front door, 63 is a back door, and 64 is a door on the ceiling. Instead of the door or shield plate described above, a bellows 66 as shown in FIGS. 24 and 25 may be provided between the adjacent movable shelves 2, 2. One end of the bellows 66 is fixed to one adjacent movable shelf 2, and the other end of the bellows 66 is coupled to the other adjacent movable shelf 2 by magnetic attraction, engagement, or other appropriate means. Furthermore, this connection can be released, and by locking a lock 67 provided at one end of the bellows 66 in the above-mentioned state, the above-mentioned state of connection can be maintained. In the state where the bellows 66 and the movable shelves 2, 2 are combined, the bellows 66 expands and contracts as the passage width between the movable shelves 2, 2 changes, and the movable shelves 2, 2
It is not possible to intrude into the passageway between the two and see inside the passageway, thus making it possible to prevent theft of stored articles.

Note that in order for the bellows 66 to expand and contract as the movable shelf 2 moves, it is necessary to provide some kind of guide means to prevent the bellows 66 from sagging. Second
In the example shown in FIG. 4, the guide arm 68 moves from the top plate of one of the adjacent movable shelves 2 to the other
is extended in a cantilevered manner, and the bellows 66 is suspended by the guide arm 68, and the movement of the bellows 66 is guided. In the example shown in FIG. 25, a guide rail 69 covering the entire range of the movable shelf device is fixed above the movable shelf device consisting of a plurality of movable shelves, and each bellows 66 is suspended and guided in common by the guide rail 69. It's becoming like that. In the example shown in FIG. 25, although the configuration is relatively simple, the relative moving distance of each bellows 66 with respect to the guide rail 69 becomes long, resulting in a large load. That point,
The example shown in FIG. 24 has the advantage that the relative movement distance of each bellows 66 with respect to each guide arm 68 is short and the load is small.

In the examples shown in FIGS. 24 and 25, one end of the bellows 66 is fixed to one of the movable shelves 2, but both ends of the bellows 66 may be connected to the movable shelf 2 with a lock.

The locking device according to the present invention is not limited to the drive type of the movable shelf, and can be applied to electric movable shelves, manual rotating handle type movable shelves, and movable shelves that are manually pushed directly. is also applicable. In the case of an electric movable shelf, the motor as the drive source may be of an appropriate type and applied.For example, it is called a brake pack or clutch brake motor, and the output shaft is connected and disconnected by an electromagnetic clutch. When an earthquake exceeding a certain level is detected, the electromagnetic clutch is used to disconnect the output shaft. This allows the motor to rotate freely as the movable shelf sways when an earthquake occurs, thereby absorbing earthquake energy and preventing the movable shelf from falling over. Of course, a motor without an electromagnetic clutch may also be used. In that case, divide the multiple movable shelves that make up the movable shelf row into two groups from the center, position the drive wheels of the movable shelves in each group on the outside, and position the free rotating wheels of the movable shelves in each group on the inside. It's good to let them do it. By doing this, when an earthquake occurs and the movable shelves shake, each group of movable shelves will end at the center, so the movable shelves will not collide with the stopper provided at the end of the guide rail and fall. This makes it possible to provide a highly safe mobile shelf device in the event of an earthquake. Furthermore, a motor without a brake may be used as the drive source.

In an electric movable shelf device, it is desirable to provide an interlock so that power is not supplied to the motor when the movable shelf is locked so that it cannot be moved.

The design of the present invention can be freely modified within the technical scope limited by the scope of the utility model registration claims.

(Effect of the invention) According to the invention, the locking device moves the movable shelves within a range of 30 mm or more in the locked state and within a range where a space between the shelves is narrower than the space between which a human body can enter. Therefore, when an earthquake occurs, the movable shelf absorbs seismic energy while moving back and forth within the above movable range, and seismic energy is not directly transmitted to the movable shelf. The movable shelf can be prevented from sliding and falling, and the stored articles can be prevented from falling. Additionally, the range in which the movable shelves can be moved in a locked state is limited to the range where the space between the shelves is narrower than the space between which a human body can fit, thereby preventing theft of stored items. be able to.
