Description

  The present invention relates to dust removal.

There are many different types of dust collectors.
For example, in the dust collector disclosed in Patent Document 1, a dust receiving portion curved in a substantially semi-conical shape and a handle attached to the bottom end of the bottom are integrally formed of an elastic body.
During use, the bottom of the dust receiving part is pressed against the floor surface with a handle to elastically deform the curved dust receiving part along the floor surface, and the dust is taken into the dust receiving part with a broom. After that, release the pressing force on the dust receiving part and return it to elasticity, gather the dust receiving part closer than the opening of the trash can, gather it in the center, and put the dust from the tip into the trash can. ing.

JP-A-6-7277

Although the dust collector having the above configuration is formed of an elastic body, it is difficult to elastically deform almost the entire semicircular dust receiving portion flatly, and the deformation state varies depending on the force. It was not possible to sweep the dust into the receiving part at once.
Further, if the dust is collected from the dust receiving portion and then elastically restored from the dust collecting form, the dust is repelled on the dust receiving portion and scattered to the outside.
Therefore, in the present invention, the dust receiving part is configured to be deformable by a simpler operation than the above conventional product, and when collecting dust, the bottom plate of the dust receiving part is surely developed so that dust can be swept away, The purpose of the present invention is to provide a dust collector that can securely put dust collected by closing the dust receiving portion when the dust is discharged.

In view of the above-mentioned problems, the dust collector of the present invention has the same shape that is connected to the bottom plate center portion of the dust receiving portion formed in a symmetric square flat plate shape and the left and right side edges of the bottom plate center portion so as to be freely raised and lowered. A bottom plate side portion composed of a flat plate, a handle formed continuously at the rear end of the bottom plate center portion so as to be bent at a predetermined angle, and elastically returnable to the bottom plate center portion so as to maintain such a bent state; Consists of a pair of left and right operation plates that also serve as a side wall for the dust receiving part, which is connected to the left and right side edges of the handle so as to be swingable in the left and right direction, and is connected to the outer side edge of the bottom plate side part so as to be able to bend and extend. The operation plate is set so as to be directed outward in an unloaded state so as to maintain a bottom plate unfolded state in which each side of the bottom plate lies on the same plane as the central portion of the bottom plate.
Also, in the above dust collector, each of the front part of the bottom plate center part and the bottom plate side part is bent so that the front descending inclined surface having the same gradient can be elastically bent and stretched in the developed state of the bottom plate with the bottom plate side part lying down. At the same time, it may be urged to bend and deform to the inclined surface.

In short, since the present invention is configured as described above, the bottom plate center portion and the left and right bottom plate side portions are developed on the same plane in a no-load state where no external force is applied to the operation plates on the left and right sides of the handle. Can be collected, and the dust collected by the conventional method can be collected by the dust receiving portion constituted by the bottom plate and the side wall (operation plate) that bends and rises at the outer edge.
In this way, the dust-collecting form can be naturally maintained in an unloaded condition where no external force is applied to the operation plate in this way. Compared to conventional products that have to collect dust on the dust receiver, the work can be done easily.
When throwing the dust collected in the dust receiver into the trash box, if the left and right operation plates are swung inward so as to face each other, the bottom plate side follows the operation plate, and the bent operation plate And the side of the bottom plate is bent with respect to the center of the bottom plate while extending and rises as a side wall, and the dust receiving part is deformed into a narrow groove shape with a narrow frontage. Even if it is a small trash can, it can be disposed of without any difficulty.
After that, just by releasing the external force applied to the operation plate, the bottom plate center part and the handle whose bending angle is widened in the above-mentioned deformation state are elastically restored to each other, and the bottom plate side part is flush with the bottom plate center part. The operation plate can be bent with respect to the bottom plate side and can be easily restored to the dust removal form without any trouble.

  Further, in the unfolded state of the bottom plate with the bottom plate side portion lying down, the bottom plate center portion and the front portion of the bottom plate side portion each bend and form a forward descending inclined surface having the same gradient so as to be able to bend and stretch elastically. By energizing it so that it bends and deforms to the surface, it is possible to further ensure and stabilize the restoration to the dust removal form and its form retention together with the elastic restoring force between the center part of the bottom plate and the handle, Practical effects such as being able to collect without taking time are great.

An embodiment of the present invention will be described below with reference to the drawings.
A dust collector 1 according to the present invention has a dust receiving part 4 comprising a bottom plate 2 whose front end is a dust inlet / outlet, side walls 3 standing on the left and right edges of the bottom plate 2, and a rear part of the dust receiving part 4. The handle 5 provided is integrally formed with a synthetic resin such as PET (polyethylene terephthalate) or PP (polypropylene).

The bottom plate 2 is a flat plate of the same shape that is formed in a symmetrically flat rectangular plate shape and is connected to the left and right side edges of the bottom plate center portion 2a through a seam J formed of a thin portion so as to be raised and lowered. And a pair of left and right bottom plate side portions 2b.
The bottom plate center portion 2a and the bottom plate side portion 2b are made of flat plates of the same thickness. The bottom plate center portion 2a is formed in an elongated isosceles trapezoid whose front end is longer than the rear end, and the bottom plate side portion 2b is connected through a joint J. A side edge having the same length as the left and right side edges of the bottom plate center portion 2a, a front edge adjacent to the one side edge and having the same length as the front end of the bottom plate center portion 2a and located on the same straight line; and the front end The bottom plate 2 is formed in a triangular shape composed of an outer edge that is inclined adjacent to each one of the side edges, and the bottom plate center portion 2a and the left and right bottom plate side portions 2b are arranged on the same plane. The

  The handle 5 is continuously formed at the rear end of the bottom plate central portion 2a so as to bend at a predetermined angle (in the illustrated example, an obtuse angle), and can be elastically returned to the bottom plate central portion 2a so as to maintain such a bent state. The base end has the same width as the rear end of the center portion 2a of the bottom plate, and is formed in a tapered strip shape that gradually decreases in width toward the tip (upper end).

  Each side wall 3 has its rear end edge connected to the left and right side edges of the handle 5 via a joint J1 made of a thin part so as to be swingable in the left and right direction, and its base is made of a thin part on the outer edge of the bottom plate side part 2b. A rectangular plate-like operation plate (hereinafter also referred to as operation plate 3) connected in a flexible manner via a joint J2, the operation plate 3 having an inner angle between its bottom and rear edge at the center of the bottom plate 2a and the handle 5 are matched to the angle of the continuous bent part, the base is formed to be the same length as the outer edge of the bottom plate side 2b, and the rear edge is formed corresponding to the appropriate height of the left and right side edges of the handle 5. From the upper end of the rear end edge to the short front end edge that stands vertically with respect to the front end of the bottom side, a hypotenuse that is descending forward is formed.

  In this embodiment, the joints J, J1, and J2 are formed at each boundary between the bottom plate center portion 2a and the bottom plate side portion 2b, the bottom plate side portion 2b and the side wall 3, and the side wall 3 and the handle 5. The bottom of the V-shaped groove is formed in a thin shape so that it can be bent depending on its material characteristics. However, if each of the constituent members 2a, 2b, 3, and 5 is configured to be able to bend and stretch, the joints J and J1 , J2 may not be formed in a V-shaped groove shape having a thin groove bottom.

By configuring the dust collector 1 as described above, the operation plate 3 is directed to the outside (the handle 5 and the operation plate 3 form an obtuse angle) in a no-load state in which no external force is applied to them. The bottom plate side portions 2b are set on the same plane as the central portion 2a so as to maintain the bottom plate unfolded state (see FIGS. 1 to 4).
In this way, the left and right bottom plate side portions 2b with respect to the bottom plate center portion 2a are lying on the same plane, and the side plate rises by bending at the seam J2 between the bottom plate 2 and the bottom plate 2 that is expanded and held. The dust receiving part 4 constituted by the operation plate 3 normally holds the dust removal form naturally without requiring any operation.
In such a state, dust collected by a dust etc. as before is collected.

When the dust collected in the dust receiving portion 4 is put into the trash box, the handle 5 is held together with the rear portion of the operation plate 3 so that the left and right operation plates 3 of the handle 5 are pressed inward so as to face each other. Shake.
As a result, the bottom plate side portion 2b is moved to the operation plate 3, and the operation plate 3 and the bottom plate side portion 2b, which are bent in the dust removing form, are bent at the joint J with respect to the bottom plate center portion 2a while being extended. 3, the bottom plate center portion 2a and the handle 5 are deformed so that the bending angle thereof is further expanded, that is, the handle 5 is turned up against the bottom plate center portion 2a (see FIGS. 5 and 6).

As a result, the dust receiving portion 4 is deformed into a concave groove shape with a narrow frontage, whereby the dust is gathered together on the bottom plate central portion 2a.
In addition, due to the above deformation of the dust collector 1, the side wall 2b and the high side wall 2b 3 with the operation plate 3 extended are provided on the left and right of the bottom plate center 2a. The dust on the 2a does not blow up, soar or drop off, preventing dust from splashing to the outside, and the direction is stable when dust is thrown from the dust receiver 4 into the trash can. Even if is small, the dust on the dust receiver 4 is not zeroed out of the trash can, and all the dust can be reliably discharged from the dust receiver 4 into the trash can.

  Then, by loosening the grip on the handle 5 and releasing the external force applied to the operation plate 3, the bottom plate center portion 2a and the handle 5 whose bending angles are widened in the above-described deformation state are restored elastically, that is, the bottom plate. The handle 5 rises with respect to the central portion 2a, whereby the bottom plate side portion 2b falls on the same plane as the bottom plate central portion 2a, and the operation plate (side wall) 3 bends with respect to the bottom plate side portion 2b to be restored. Return to the dust removal mode.

Next, a modified example of the dust collector 1 will be described with reference to FIGS. This dust collector 1 is a modification of the bottom plate 2 in the first embodiment (the dust collector shown in FIGS. 1 to 6), and other configurations are the same as the first embodiment. Corresponding portions are denoted by the same reference numerals in the drawing and description thereof is omitted.
In this modification, the bottom plate side portion 2b is in a flattened bottom plate state, and the front portion of the bottom plate center portion 2a and the front portion of the bottom plate side portion 2b is elastically provided with the inclined surfaces 6a, 6b having the same gradient. Are bent so as to be able to bend and stretch, and are urged to bend and deform toward the inclined surfaces 6a and 6b.

With this configuration, in particular, the inclined surface 6a in front of the center portion 2a of the bottom plate is urged so as to bend and deform downward in order to maintain the inclined form. The bottom plate side portion 2b is always urged in the lying down direction (downward), and the side wall 3 and the handle 5 are also urged through the bottom plate side portion 2b so as to be transformed into a dust removal form. The urging force of the inclined surface 6a is combined with the elastic restoring force between the center portion 2a of the bottom plate and the handle 5, thereby making it possible to restore the dust removal form and maintain the form more reliably than in the first embodiment. And stabilized.
In addition, the inclined surface 6b itself is bent so as to be always bent and deformed so as to hold the inclined form in front of the inclined surface 6a in the same manner as the inclined surface 6a. It deforms and forms a slope 6 for introducing dust (inclined surfaces 6a, 6b) in front of the bottom plate 2.

Therefore, in the dust collector 1 in the present embodiment, the operation plate 3 is directed outwardly in the same manner as in the first embodiment in a no-load state in which no external force is applied to the operation plate 3, and is further forward of the bottom plate 2. The slope 6 is formed on the bottom plate, and the bottom plate side portion 2b is in a collapsed bottom plate unfolded state.
This dust removal mode is naturally held without requiring any operation as in the first embodiment. There is no need to collect.

Further, by grasping the handle 5 together with the rear portion of the operation plate 3 and pressing and swinging the operation plate 3 inward so as to face each other, the bottom plate side portion 2b follows the operation plate 3 and bends in a dust removal form. While the deformed inclined surface 6b is extended, the operation plate 3 and the bottom plate side portion 2b which are similarly bent are bent at the joint J with respect to the center portion 2a of the bottom plate, and rise as side walls 2b and 3 Along with the deformation, the inclined surface 6a that has been bent and deformed together with the inclined surface 6b also extends, and the handle 5 is deformed so as to be turned up against the center portion 2a of the bottom plate.
In this deformed state, the bottom plate center portion 2a and the bottom plate side portion 2b are in an extended state such that the front inclined surfaces 6a and 6b are on the same plane. The side wall 2b extending to the left and right of the central portion 2a and the operation plate 3 are deformed into a narrow concave groove with a raised front, and the dust collected in the form of dust removal is gathered together on the bottom plate central portion 2a. It is possible to reliably discharge all the dust from the dust receiving part 4 into the trash box without being scattered or spilled outside while the trash is being transported to the trash box or being thrown into the trash box.

  Then, by loosening the grip on the handle 5 and releasing the external force applied to the operation plate 3, as described above, the elastic restoring force between the bottom plate center portion 2a and the handle 5 and the biasing force of the inclined surfaces 6a and 6b are used. It returns to the dust removal mode having the slope 6 in front of the dust receiver 4.
