Description

  The present invention relates to a bogie device in an industrial vacuum cleaner having a structure in which a bogie is disposed at the lower portion of a vacuum cleaner body.

  Industrial vacuum cleaners are used in a wide variety of fields such as stores, warehouses, factories, etc., and the environments in which they are used vary. Accordingly, the suctioned object is not limited to solid dust, and for example, water or oil spilled on the floor is also a target. In this situation, in addition to a flat floor, steps and various grooves, protrusions, etc. also occur on a daily basis, and since it is drawn around, it can have good running performance and stability Required. However, industrial vacuum cleaners that attempt to answer these requirements positively are not known. Furthermore, since industrial vacuum cleaners have many types of attachments such as suction hoses, suction pipes, and various nozzles in order to meet various suction targets, it is difficult to store and organize them. . However, there is no known industrial vacuum cleaner that considers storage and organization of accessories and equipment.

  In order to improve the stability, the distance between the wheels formed of casters or the like may be sufficiently widened, but this causes a problem that the wheels take up space during storage. Therefore, as can be seen in the electric vacuum cleaner disclosed in Japanese Patent Laid-Open No. 6-105775, a part of the wheel must be disposed under the tank. Further, for example, in the cleaning apparatus disclosed in Japanese Patent Laid-Open No. 2002-102130, a dedicated carriage for movement is equipped, but the wheel is not provided until it projects outside the planar shape of the main body that occupies the largest area. . For this reason, it tends to be unstable, and falls easily.

  The present invention has been made paying attention to the above points, and the problem is to provide a cart device for an industrial vacuum cleaner that does not take up space during storage and exhibits excellent running stability. is there. Moreover, the other subject of this invention is providing the trolley | bogie apparatus in the industrial vacuum cleaner provided with the function for storage and arrangement of accessories and fixtures.

  In order to solve the above-described problems, the present invention assumes a polygon having a size that is substantially in contact with the outside of the main body, and is separated from the main body with respect to an industrial vacuum cleaner having a configuration in which a carriage is disposed at the lower portion of the main body of the vacuum cleaner. Further, a means is provided in which the wheel is installed at a position corresponding to the corner of the polygon or a position in the vicinity thereof.

  The present invention is intended for an industrial vacuum cleaner having a structure in which a carriage is arranged in the lower part of the vacuum cleaner body. This configuration includes a structure in which the vacuum cleaner body is mounted on the carriage, The thing which provided the wheel in the state by which the vacuum cleaner main body is arrange | positioned is included. That is, the cart in the present invention means that having a wheel attached to a cart frame having a structure different from that of the main body, and can include a wheel alone attached directly to the main body.

  In the device of the present invention, it is important to arrange the carriage so that it protrudes as far as possible, and it requires a minimum amount of extension to obtain sufficient stability. . Therefore, in the present invention, a polygon having a size almost in contact with the outside of the main body is assumed, and wheels are respectively installed at positions corresponding to or near the corners of the polygon away from the main body. It is. Polygons are often judged to be squares, rectangles or trapezoids, but triangles or hexagons are also assumed.

  If it is a polygon of a size almost in contact with the outside of the main body, it is almost the same as the plane area of the main body, and it does not protrude unnecessarily. When the planar shape of the main body is a circular shape or a shape close to it, the position corresponding to the corner of the polygon or the position in the vicinity thereof is located outside the main body. Stability can be obtained even during traveling. Therefore, it can be said that the present invention obtains sufficient stability with the minimum amount of overhanging wheels.

  In addition, struts can be provided upright at intervals between the main body at positions corresponding to the corners of the polygon or in the vicinity thereof. Providing a column in a position protruding from the main body makes it possible to wrap hoses around the space using the space between the main unit and at the same time, use the column itself as an attachment site, for example, a duct or nozzle. It means that it can be inserted into the column, that is, it has functions for storage and organization.

  The main body of the vacuum cleaner is vertically long and has a cylindrical shape, and the carriage frame to which the carriage is attached has an intersecting shape similar to a rectangular diagonal line that substantially circumscribes the cylindrical shape, and is provided at the tip of the carriage frame. The configuration in which the support is provided by using the bolts to which the wheels are attached is meaningful in the present invention. This is because a so-called scissors-type vacuum cleaner composed of a cylindrical body is easy to fall down, and the fall prevention measures according to the present invention are more effective than other types.

  Moreover, when taking the structure which attaches a trolley | bogie to a trolley | bogie frame, as a trolley | bogie frame, it is desirable to have the cross | intersection form similar to the rectangular diagonal assumed as what is substantially circumscribed by the said cylindrical shape. This is because it belongs to the simplest form as a bogie frame, requires a minimum amount of overhang, and has a structure that allows easy mounting of wheels.

  A wheel can be attached to each end of the carriage frame by a bolt, and the bolt can also be used as an attachment base for the column. This is reasonable because it is not necessary to provide a mounting partner for the column. And although it is necessary, the front-end | tip part of the trolley | bogie frame protruding outside can be effectively utilized for another use called a wheel mounting base. It is desirable to use a caster wheel having a diameter as large as possible. This is because a large-diameter caster wheel has a higher running stability than a small-diameter wheel, and also has a higher minimum ground clearance and is thus far away from a dirty floor.

  The present invention is constructed and operates as described above, and it has sufficient stability with a minimum amount of overhanging wheels. Therefore, it saves space during storage and is excellent. There exists an effect that the trolley | bogie apparatus in the industrial vacuum cleaner which exhibits driving | running | working stability can be provided. Moreover, according to this invention, the cart apparatus in an industrial vacuum cleaner which has the function for storage and arrangement of accessories and fixtures and has novelty can be provided.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows the appearance of an industrial dry / wet vacuum cleaner 10 according to the present invention, wherein 11 is a suction unit located at the upper part, and 12 is a collection part located at the lower part. The suction port 13 located between the suction hose 14 and the suction port 13 is provided on the suction unit side. The collection unit 12 in the illustrated example is a cylindrical tank 15. Therefore, it can be said that the cleaner body 16 including the suction unit 11 and the recovery unit 12 has a vertically long and cylindrical shape.

  Regarding the industrial vacuum cleaner having the above-described configuration, the present invention assumes a polygon 17 having a size substantially in contact with the outside of the vacuum cleaner body 16. In the example shown in FIG. 2, the vacuum cleaner body 16 has a cylindrical shape, and there is no appendage or structural difference depending on the direction of the cylinder. Therefore, the assumed polygon 17 is a square. And in the position away from the cleaner main body 16 corresponding to the corner | angular part of the said polygon 17, the wheel 20 is each installed with the structure which is mentioned later.

  In the illustrated example, as the carriage frame 18 to which the wheels 20 are attached, the carriage frame 18 having an intersecting shape similar to a rectangular diagonal line substantially circumscribing the cylindrical shape is used. The bogie frame 18 is formed by assembling a steel U-shaped member 19 in a substantially X shape, and a large-diameter caster wheel as a wheel 20 is attached to the tip of the bogie frame 18 from below by using bolts 21. (See FIG. 3B). Although it is difficult to define the large diameter of the large-diameter caster wheel, for example, it is one condition that the maximum size is such that it does not go out of the polygon 17 when it is turned inward.

  Further, in the present invention, the columns 22 are provided using bolts 21 each having a wheel 20 attached to the tip of the carriage frame 18. That is, the wheel mounting bolt 21 is used as a mounting base for the column 22. The column 22 is used to insert a so-called attachment 23 such as a duct or a nozzle, or is used to wrap a hose for attaching the nozzle to the cleaner body 16 around the tank 15. Therefore, the dimension is set to a length required for inserting the attachments 23 and fixing the wound hoses.

  In the figure, reference numeral 25 denotes a resin cap attached to the upper end of the support column, but the cap has a slightly swollen shape and a conspicuous color, so that it has a function of preventing detachment and is easy to use. 26 is a caster mounting nut, and 27 is a handle, which is attached to the upper side surface of the tank 15.

  As shown in FIG. 1, the industrial vacuum cleaner 10 to which the cart device according to the present invention configured as described above is connected, connects the suction hose 14 to the suction port 13 at the connection portion, and extends the power cord 28. While moving, the nozzle 29 sucks solids such as dust on the floor and liquids such as dirty water and uses them for cleaning work. At that time, since the wheel 20 is formed of a large-diameter caster wheel, even if it is quickly moved, the wheel 20 stably follows, and there is little risk of being caught by a step or the like, and the work can be smoothly performed.

  When the industrial vacuum cleaner 10 is not used, so-called attachments 23 such as a duct 30 and a nozzle 29 can be inserted into the column 22 as shown in FIG. As the attachments 23, a nozzle 31 with a brush and a nozzle 32 for slits are shown. The hoses can be wound around the tank 15 and placed. The power cord 28 can be hung on the hook 33 at the top of the main body. Therefore, everything necessary for one vacuum cleaner can be put together, and there is no fear of loss, so it is highly practical.
