Description

  The present invention relates to a dust collector that can be brought into and moved to a construction site or the like.

  In general, a dust collector sucks air by a dust collecting fan that is driven to rotate by a motor, and dust contained in the sucked air is separated by a filter and collected in a tank.

  By the way, as an environment where such a dust collector is used, there are construction sites and renovation sites other than homes, and cleaning of dust scattered around by work such as cutting, cutting, grinding, etc. with electric tools at construction sites etc. A relatively large dust collector for use is also known. This type of dust collector is usually taken home by car every day after work to prevent theft, etc., but depending on the location, due to problems with parking lots and empty spaces, it is not possible to enter the car near the site There are also many.

  A conventional dust collector is provided with a tank below a head portion in which a motor and a dust collecting fan are incorporated, and can move on a floor surface by a plurality of casters rotatably provided on the lower surface of the tank. Here, the head portion has a head cover that covers a start / stop switch provided at an arbitrary position, and a convex handle is formed on the upper surface of the head cover (see, for example, Patent Document 1). .

JP 2004-073687 A

  Thus, when the dust collector is moved to the place where it is used, the main body is lifted and moved by the handle on the upper surface of the head cover. Alternatively, the handle on the upper surface of the head cover may be pushed by hand and the main body may be moved on the floor surface while rolling the caster. In this case, the height of the main body of the dust collector is low, and fatigue is difficult.

  By the way, when transporting a dust collector used in a construction site by car, depending on the location as mentioned above, there are many cases where it is not possible to enter the car near the site due to problems such as parking lots and empty spaces. The main body must be lifted and carried by a long distance (eg, about 300 m) with a handle, or the main body must be moved while rolling the caster by pushing the handle with the hand, which is inconvenient and inconvenient. It was.

  In addition, when the dust collector is loaded on a car (especially a truck bed) and transported, the caster provided at the bottom of the tank is rotatable, so that the main body moves and it is necessary to fix the main body with a rope or the like. Yes, the work was also troublesome.

  The present invention has been made in view of the above problems, and an object thereof is to provide a dust collector capable of improving the operability of transporting and moving the main body.

  In order to achieve the above object, a first aspect of the present invention is directed to a motor, a dust collecting fan that is rotationally driven by the motor, and a head portion that houses a switch for operating and stopping the motor, and a lower portion of the head portion. In a dust collector comprising a tank provided and provided with a rotatable caster at the lower part of the tank, a slide handle is provided on the tank or the head part so as to be slidable in a vertical direction or a diagonally vertical direction by hole fitting, An elastic body is attached to the lower end of the slide handle.

  According to a second aspect of the present invention, in the first aspect of the invention, a plurality of sliding guide portions are provided on a side portion of the tank, and the sliding guide portions are formed in an inverted U shape with a pipe material. The slide handle is slidably inserted.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, a knob bolt that is screwed into a screw hole orthogonal to the sliding direction of the slide handle is provided, and the sliding of the slide handle is locked by the knob bolt. It is characterized by doing so.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the elastic body is detachably attached to a lower end of the slide handle.

  According to the first and second aspects of the invention, when the dust collector is moved, the slide handle is lifted upward until the elastic body hits the sliding guide portion of the tank portion, and the main body is moved by pulling the slide handle by hand. Can be made. For this reason, even if it is not possible to enter a car close to the site due to problems with parking lots and empty spaces depending on the location, the dust collector can be operated with good workability to a construction site that is a considerable distance away (for example, about 300 m). It can be easily moved without much effort.

  Also, if the slide handle is pushed down to the floor surface and an elastic body such as rubber attached to the lower end is pressed against the floor surface, the elastic body functions as a stopper and a large amount generated between this and the floor surface. Since the movement of the dust collector is locked by the frictional force, for example, the dust collector can be carried on the truck bed as it is, and the troublesome work such as fixing the main body with a rope as in the prior art can be omitted.

  Then, by simply adding a slide handle and an elastic body, the above effects can be achieved with a simple structure and at a low cost.

  According to the third aspect of the present invention, since the sliding of the slide handle can be locked by the knob bolt that is screwed into the screw hole orthogonal to the sliding direction of the slide handle, the slide handle can be set according to the preference of the operator. It can be fixed at an arbitrary height position, the workability is improved, and the dust collector can be easily moved with better workability. Further, if the slide handle is pushed down to the floor surface and the slide handle is fixed with the knob bolt in a state where the elastic body attached to the lower end thereof is deformed by a predetermined amount, the deformation amount of the elastic body can be maintained at a predetermined value. It is possible to secure a predetermined frictional force between the elastic body and the floor surface, and to more reliably lock the movement of the dust collector on the floor surface.

  According to the invention described in claim 4, since the elastic body can be attached to and detached from the lower end of the slide handle, the elastic body is removed from the slide handle, for example, when the dust collector is not used and stored. After that, the slide handle can be removed from the tank of the main body, which is convenient because the storage space for the dust collector can be small.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1 is a partially broken side view showing a state in which a slide handle of a dust collector according to the present invention is pulled up, FIG. 2 is a partially broken rear view of the dust collector, FIG. 3 is a plan view of the dust collector, and FIG. It is a partially broken side view which shows the state which pushed down the slide handle.

  The dust collector 1 according to the present invention is configured by providing a drum-shaped tank 3 below the head portion 2 and rotatably supporting a total of four casters 4 and 5 on the lower surface of the tank 3 so as to be rotatable. The main body composed of the head portion 2 and the tank 3 can be freely moved on the floor surface by casters 4 and 5. In the following description, the direction of the head portion 2 of the dust collector 1 shown in FIG. 1 is upward, and the direction of the casters 4 and 5 is downward.

  Here, a motor (not shown) as a drive source and a dust collecting fan (not shown) that is rotationally driven by the motor are built in the head unit 2, and a switch 6 that operates and stops the motor. (See FIG. 3).

  The tank 3 is provided with a filter (not shown) inside, and is used for separating and collecting dust contained in the air sucked by the dust collecting fan built in the head portion 2 by the filter. is there.

  Incidentally, in the dust collector 1 according to the present embodiment, a pair of left and right block-like sliding guide portions 7 and 8 are arranged on the back surface of the head portion 2 (the right end surface in FIG. 1) in a total of 4 steps. One is provided. In the present embodiment, the sliding guide portions 7 and 8 are formed integrally with the tank 3. However, the sliding guide portions 7 and 8 may be configured separately from the tank 3 and retrofitted to the tank 3.

  Circular holes 7a and 8a are respectively provided in the sliding guide portions 7 and 8 in the vertical direction, and the circular holes 7a and 8a are slides formed in a reverse U-shape in a front view with a pipe material. The left and right vertical portions 9a of the handle 9 are inserted so as to be slidable up and down. A columnar shape having an outer diameter larger than the outer diameter of the slide handle 9 is formed at a lower end portion projecting downward from the left and right sliding guide portions 8 on the lower side of the left and right vertical portions 9 a of the slide handle 9. An elastic body 10 such as rubber is detachably attached.

  In the dust collector 1 configured as described above, when the switch 6 of the head unit 2 is turned ON, the dust collecting fan is rotationally driven by a motor (not shown) built in the head unit 2, and the suction of the tank 3 (not shown). Air is sucked from the mouth, and dust contained in the sucked air is separated by a filter (not shown) in the tank 3 and collected in the tank 3.

  Thus, when the dust collector 1 is moved in the construction site, as shown in FIGS. 1 to 3, the left and right elastic bodies 10 are slid until the end surfaces of the left and right elastic bodies 10 come into contact with the lower surface of the lower slide guide portion 8. The handle 9 is pulled up. Then, if the back side of the dust collector 1 on which the slide handle 9 is provided is tilted around the caster 4, and the main handle is pulled by holding the horizontal handle 9 b of the slide handle 9 in this state, the main body is moved by the caster 4. You can move freely.

  Therefore, the worker can easily move the dust collector 1 to a desired place without a great effort with a comfortable posture and high workability. Also, even if the car cannot be brought close to the site due to problems with parking lots or empty spaces depending on the location, the dust collector 1 can be operated with good workability to a construction site that is a considerable distance away (for example, about 300 m). It can be moved without much effort.

  On the other hand, when the dust collector 1 is carried on a truck bed (not shown) and transported to the construction site, or brought home from the construction site, the slide handle 9 of the dust collector 1 placed on the truck bed is elastic as shown in FIG. Push down 10 until it touches the floor. Then, since the elastic body 10 functions as a stopper and the movement of the dust collector 1 is locked by a large frictional force generated between the elastic body 10 and the floor surface, even if the main body is not fixed with a rope or the like as in the past, Moreover, even if the truck is slightly shaken, the dust collector 1 does not move on the loading platform. For this reason, the dust collector 1 can be easily carried on the truck bed as it is, and troublesome work such as fixing the main body with a rope as in the prior art can be omitted.

  Furthermore, since the elastic body 10 can be attached to and detached from the lower end of the slide handle 9, for example, when the dust collector 1 is not used and stored, after the elastic body 10 is removed from the slide handle 9, The slide handle 9 can be removed from the tank 3 of the main body, which is convenient because the storage space for the dust collector 1 can be small.

  Thus, in the dust collector 1 according to the present embodiment, the above-described effects can be achieved with a simple structure and at low cost simply by adding the slide handle 9 and the elastic body 10.

  Incidentally, as shown in FIG. 5, for example, a screw hole 7b perpendicular to the sliding direction of the slide handle 9 is formed in the sliding guide portion 7, a knob bolt 11 is screwed into the screw hole 7b, and the knob bolt 11 is turned. Then, the slide handle 9 may be fixed to the sliding guide portion 7 to lock the sliding.

  If the said structure is employ | adopted, the slide handle 9 can be fixed in the arbitrary height positions according to an operator's liking, operativity is improved, and the dust collector 1 can be moved easily with sufficient workability | operativity. .

  Also, if the slide handle 9 is pushed down to the floor surface and the slide handle 9 is fixed by the knob bolt 11 with the elastic body 10 attached to the lower end thereof being deformed by a predetermined amount, the deformation amount of the elastic body 10 is set to a predetermined value. Thus, a predetermined amount of frictional force can be ensured between the elastic body 10 and the floor surface, and the movement of the dust collector 1 on the floor surface can be more reliably locked.

  In the present embodiment, a configuration in which the slide handle 9 is provided so as to be slidable in the vertical direction is employed. However, a configuration in which the slide handle 9 is provided so as to be slidable in the oblique vertical direction may be employed. Further, although the slide handle 9 is provided in the tank 3, a configuration in which the slide handle 9 is provided in the head portion 2 may be employed.

  The present invention is particularly useful for a relatively large dust collector that is used at a construction site or the like and carried on a truck.
