Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier box for removably adsorbing to a roof made of a magnetic material such as a vehicle, and more particularly to an adsorbent attaching / detaching device for adsorbing and fixing it by an easily attachable / detachable mechanism.

[0002]

2. Description of the Related Art There is a portable storage device that is detachably installed on a roof of a vehicle or the like and is used for transporting small portable articles and for storing body covers, umbrellas and the like.

Conventionally, as a carrier box to be mounted on a roof of a vehicle or the like, a carrier box which is directly fixed to a roof of an automobile by using fasteners, or a left and right roof edge portion, for example, a rain gutter projecting piece is used. 2. Description of the Related Art There is a device in which a pair of mating standing pieces and a supporting rod mounted between them are attached, and a carrier box fixing member is provided on this supporting rod to fix the carrier box. In this device, a vertical piece for fixing the supporting rod is screwed and fixed by using a screw or the like so as to sandwich the rain gutter protruding piece. Therefore, the fixing of the support rod is strong, but it takes time to attach and detach the support rod, and the structure is complicated, and it is unsightly to say that the desired shape is desired in terms of appearance.

There is also a carrier box having a suction plate for sucking an object to be adsorbed by forming a soft plastics or rubber into a plate state and making the inside of the plate a negative pressure. Since this one is attracted by the suction force due to the negative pressure, not only the negative pressure is physically regulated and the suction force is limited, but when the object to be attracted is the roof of the vehicle, the roof is hot in summer. Therefore, the suction cup made of soft plastics tends to deteriorate early and lack stability. Also, if water droplets are attached to the surface of the adsorbent and the surface of the adsorbent is protectively coated with a member containing a surfactant, the interfacial tension between the suction plate and the surface of the adsorbent decreases. There is a risk that the suction plate will be displaced from the fixed surface of the object to be adsorbed, and there is a risk of falling when the vehicle is traveling at high speed or on a rough road with vibration.

Apart from this, as shown in FIG. 3, there is also a carrier box for fixing magnets to the legs. A magnet 71 having a concave contact surface with the object to be attracted is attached to a leg portion 39 of the fixed base 38 facing the outer contour of the vehicle with a fixing tool 92 such as a magnet to the fixed base. When the object to be attracted is a magnetic substance, the attraction effect is increased by increasing the bottom area of the magnet 71, but the greater the attraction effect, the greater the desorption force required.

The carrier box which is detachable and can be easily attached to the roof as described above is used for accommodating a relatively expensive device for the purpose of preventing theft and other purposes. For example, the specific low power wireless telephone device is convenient and useful when mounted on a plurality of vehicles and used for communication between vehicles and communication between the vehicle and the outside of the vehicle. Since the communication reach distance is short when used in the vehicle compartment, the communication reach distance can be extended by temporarily installing it outside the vehicle compartment, for example, on the roof and using it by remote control from the vehicle interior. For this reason, when not in use, it must be detachable from the roof and portable, and adsorption must be easy and fast. However, with the above structure, it is possible to easily adsorb, but it is difficult to quickly desorb.

Generally, such a carrier box is assured of safety as it is installed more firmly so as to withstand high-speed traveling and vibrations on bad roads. It is not suitable for those that are repeatedly attached and detached.

[0008]

SUMMARY OF THE INVENTION In view of the above situation, the present invention provides a portable storage device that can be detachably and securely attached to an outer shell made of a magnetic material, and at the same time, can be easily removed, and its adsorbent. An attempt is made to provide a detachable device.

[0009]

In order to achieve the object, the present invention provides a portable storage container having a fixed base which faces a surface to be attracted and which is not attached to the bottom of the fixed base. A magnet facing the attraction surface is provided, and an attaching / detaching device comprising at least one movable protrusion that is movable in the vertical direction in accordance with the rotation of the lever attached to the portable container is formed. is there. Further, according to the present invention, in a portable storage device in which a housing is constituted by a fixed base that faces the attracted surface with a space and a cover member that is fitted into the fixed base and can be opened and closed, a predetermined direction is provided in the plane direction of the fixed base bottom surface. At least one leg bottom face protruding from each other at intervals and facing the attracted surface is composed of each magnet, and the legs are unequal from each other. The attachment / detachment device is formed of at least one movable protrusion which is arranged at intervals and is movable in the vertical direction in accordance with the rotation of the lever.

Further, according to the present invention, a lever, which is continuously provided along the fixed base with a locking portion composed of a hole for laterally connecting the left and right shafts of the fixed base and a shaft as a pivot, and the lever is rotated in the vertical direction. As a result, the movable projection protruding downward from the protective body and the tip of the movable projection protruding from the bottom surface of the leg portion according to the turning position of the lever.

Furthermore, the present invention provides that the protective body opening through which the movable protrusion penetrates has a diameter somewhat larger than the bottom surface of the movable protrusion and smaller than the flange, and the edge portion is reduced in diameter to make sliding contact with the movable protrusion. It is what

[0012]

The stronger the magnet attracting force is, the better the magnet is, and the safety is assured. However, it is difficult to remove the magnets. However, if the magnets are removed one by one, the force is relatively small. However, focusing on easy removal, the left and right locking parts of the fixed base are used as fulcrums, levers connected from this pivot along the fixed base are used as operating points, and levers with movable protrusions as force points are used. A large force is applied to the suction surface.

Further, the movable projections are arranged between the respective leg portions, and are arranged at unequal intervals from the leg portions, and are movable in the vertical direction as the lever is rotated. After exerting a force on a part of the plurality of attracted magnets to separate them, the other magnets are separated. As a result, the plurality of magnets can be separated with a small force.

When the lever is operated, the bottom of the movable projection housed inside the fixed base projects below the protective body, and further projects from the bottom surface of the magnet fixed to each leg so as to project at least one magnet. Release the magnet from the attracted surface.

Further, the protective body opening hole through which the movable projection penetrates has a diameter somewhat larger than the bottom surface of the movable projection and smaller than the flange, and the edge portion has a reduced diameter so that the movable projection is slidably contacted.
Once the movable protrusion is moved inward of the protective body, it does not protrude from the protective body unless the lever is rotated.

EXAMPLE As an example, a case where a portable storage device for storing a wireless telephone device is installed in a vehicle will be described. The portable storage device according to the present invention is used while being fixed to the roof of a vehicle by suction. For example, a portable storage device is optionally mounted on the roof above the driver's seat in the passenger compartment to remotely control the wireless telephone device from the passenger compartment. As a result, not only the communication reach becomes longer than when the vehicle is used in the passenger compartment, but also when it is not used, it can be easily attached and detached to prevent theft.

FIG. 1 is a view showing the structure of a portable storage device, and FIG.
Is a side view and FIG. B is a plan view. In the figure, a portable storage device 1 for storing a wireless telephone device 9 is constituted by a fixed base 3 and a cover member 2 which is fitted into the fixed base and can be opened and closed. The bottom surface of the fixed base is a protector 4 formed of a member such as a resin, and the protector 4 protrudes at a predetermined interval in the plane direction of the protector 4 facing the fixed base and serves as an attracted surface of the roof. There are a plurality of front and rear legs 32 facing each other, and the magnets 7 are fixed to the bottom surfaces of the legs.

FIG. 2 is a cross-sectional view showing the structure of the movable lever portion and the movable protrusion. FIG. 2a shows a state in which the lever is pushed down and FIG. 2b shows a state in which the lever is raised. A hole 35 for inserting the shaft is formed in the left and right standing portions 34 of the fixed base 3, the shaft 11 is engaged, and the shaft 11 is horizontally rotatably mounted.

At the front outer edge of the fixed base 3, a lever 5 is provided which is movable in the vertical direction starting from the inner surfaces of the left and right holes 35, is supported via a shaft 11, and the tip 5 of the lever 5 is provided.
1 is formed in a fork shape with a notched tip. One end of the spring 12 wound around the shaft 11 is fixed to the base 36 of the fixed base 3 at the other end 51, and the end 51 is always fixed to the base 3.
It fires at 6.

From the base 36 facing the tip 51 to the pin 10
Are erected downward, and the movable projection 8 formed of a non-magnetic material such as a resin having a hole 81 through which the pin 10 is inserted is engaged in a loose fit state. 81
Can be easily moved up and down. A flange 82 is formed in the middle of the outer peripheral surface of the conical movable projection 8, and the notched tip 51 described above is slidably held between the upper surface of the flange 82 and the base portion 36. A hole 4 having a diameter slightly larger than the bottom surface of the movable projection 8 and smaller than that of the flange 82 in the protective body 4, and the edge portion 42 of which has a reduced diameter so as to be in sliding contact with the movable projection 8.
1 is opened, and the outer peripheral surface of the movable projection 8 can be freely slid in the vertical direction.

Therefore, in the spring 12, the tip 51 is always the base 3
6 is fired, the flange 82 of the movable projection 8 can be pushed up to a position where it is regulated by the tip 51 when the lever 5 is in a state of suction with the pushed surface. Edge 42 that has a reduced diameter once pushed up
Therefore, the movable projection 8 does not fall naturally. Then, the bottom portion 83 of the movable protrusion 8 has a surface FL that is substantially the same as the bottom surface of the protective body 4.

When the lever 5 is pushed up against the spring 12 in the direction shown in the drawing and the arrow, the tip 51 pushes down the flange 82, so that the outer peripheral surface of the movable projection 8 easily passes through the reduced edge 42. It can move downward in the range of the distance h shown. Therefore, the bottom portion 83 of the movable projection 8 is located below the magnet 7.

Since the movable protrusions 8 are arranged between the front and rear legs 32 and at an unequal interval from the front and rear legs 32, at least one of the front and rear magnets 7 is covered by pushing down the movable protrusions 8. Removed from the suction surface. As a result, the attraction force of the other magnets 7 is weakened and the entire plurality of magnets are removed from the attracted surface.

In the embodiment, the case in which the portable storage device for storing the wireless telephone device is applied to the roof is shown. However, this device changes the shape of the storage device so that the indicator light of the patrol car and the alarm sensor storage device can be stored. You can also use it. Further, if the attracted surface is a magnetic substance, it is applicable to the attracted surface having a step other than a flat surface or a curved surface. Therefore, other than the embodiments described above, various modifications can be made without departing from the scope of the present invention.

[0025]

EFFECTS OF THE INVENTION With a simple structure of a lever movable vertically, a spring, a pin standing downward from the base, and a movable projection, the movable projection can slide freely in the vertical direction.

Since the tip of the spring always shoots toward the base, the flange of the movable projection can be pushed up to the tip and is pushed up once when the lever is pushed down to the attracted surface. Since the movable projection does not naturally fall due to the reduced diameter edge, the bottom of the movable projection does not hinder the handling.

Since the movable protrusions are arranged between the front and rear legs and at an unequal interval from the front and rear legs, the bottom of the movable protrusion resists the attraction force of the magnet by pushing down the movable protrusion. The attracted surface is pushed, and as a result, at least one of the front and rear magnets is removed from the attracted surface. This weakens the attraction force of other magnets and removes the entire magnets from the attracted surface.Even if the total attraction force of the magnets is strong, the magnets can be easily removed from the attracted surface. it can.

Since a plurality of magnets are used, the attracting force is strong, and it can be used not only on a highway or a bad road with severe vibration, but also because the structure is simple, the manufacture is easy and the economic effect is high.

Since the portable storage device uses a plurality of magnets, it can be used without any problem even if the attraction force of one magnet drops, for example.
