Description

[Detailed description of the invention] This invention provides a pedal-openable container used to store dust, etc. This relates to a pedal structure for opening and closing M.

Store the inner container, attach the upper part of the container body and fasten it,
The lid of the container can be opened by stepping down on the bottom of the bottom front of the container, allowing you to pour dust into the inner container or take it out. It is widely used as a storage pot.

The conventional pedal structure for containers such as those mentioned above supports the middle of the pedal shaft with a fulcrum, and when the pedal provided at the tip of the pedal shaft is depressed, the lid push-up bar connected to the rear end is raised and the lid is pushed. However, with the balance structure, if you try to get the two-stroke movement of the lid push-up rod to raise and lower, a large amount of force is required on the pedal blade, and the lid opening/closing operation is not smooth. However, there was a problem that the structure became complicated.

This idea was developed to solve the problems mentioned above, and it converts the downward motion of the pedal into rotational motion to raise the lid push-up bar, allowing the lid to be lifted with a light pressing force. It is an object of the present invention to provide a pedal structure that allows for a simple opening operation as well as a simplified structure.

In order to solve the above-mentioned problems, this invention has a bent piece for connecting with the lid push-up bar at the rear end of the straight part, a tip bent piece bent on the opposite side of the bent piece on the tip side, and an end of this bent piece. A state in which the pedal shaft is provided with a tip piece that is bent in the direction of extension of the straight part to form a pedal shaft, and the bent tip piece and the tip piece of the pedal shaft protrude toward the front side of the front part of the lower bottom frame of the container body. The pedal shaft is held in a straight line by a recess provided to rotatably support the tip of the straight part, and a pedal support provided at the rear of the bottom frame to rotatably support the rear end of the straight part. A pedal is supported so as to be freely rotatable about the axis of the part, and a pedal whose lower surface rests on the tip end piece is attached to the front of the bottom frame so as to be able to swing up and down, and a connection provided at the rear end of the pedal shaft. At the end of the bending piece,
The upper end of the push-up bar is connected to the lid hinge, and the lower end of the push-up bar is connected to the lid hinge.

This invention has the above-mentioned configuration and operates as follows.

When you step down on the pedal attached to the front of the bottom frame, the tip of the pedal shaft on which this pedal rests rotates and descends around the axis of the straight part, and rotates around the straight part of the pedal shaft. The movement causes the connecting bending piece at the rear end to rotate upward, pushing up the push-up rod connected to the end.

The push-up bar pushes up the lid via the hinge by its upward movement, and the lid rotates upright around the pin of the hinge to open the upper end opening of the container body, allowing dust to be thrown into the container body.

When the pedal is released, the lid falls down in the closing direction due to its own weight, and the connecting bending piece of the pedal shaft is rotated and lowered via the waist push-up rod, so the pedal shaft rotates around the straight part, and the tip The piece pivots up to push the pedal into the raised position and the lid closes the top opening of the container body.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, the container includes a container body 1 formed in a cylindrical shape,
A lid 4 attached to the upper part of the main body 1 with a fixed hinge 2 and a lid hinge 3, a bottom frame 5 attached to the lower part of the main body 1, a pedal shaft 6 supported by the bottom frame 5, and a front part of the bottom frame 5. It is comprised of a pedal 7 attached to the top and a push-up bar 8 that connects the rear end of the pedal shaft 6 and the lid hinge 3.

The fixed hinge 2 is fixed to the upper rear surface of the container body 1 by means such as riveting, and the lid hinge 3 is attached to the fixed hinge 2 so as to be able to swing up and down by fitting a pin and a hole. The rear part of the lid 4 is an elastic plate 9
The upper end hook portion 11 of the push-up bar 8 is fixed via a slipping prevention means such as the above, and passes through a long hole 10 provided in the container body 1 and the fixing hinge 2, and is connected to the lid hinge 3.

The bottom frame 5 is provided with a groove 12 between the inner and outer circumferential walls into which the lower end of the container body 1 fits, and although the details are not shown in the drawing, there is a hooking hole 13 provided in the lower part of the container body 1 and a retaining hole provided in the inner circumferential wall. By engaging the engaging pieces, the container body 1 fitted into the groove 12 and the bottom frame 5 are fitted and integrated.

A pedal support wall 14 is provided at the front of the bottom frame 5, and a support recess 16 for the pedal shaft 6 is provided at one end of a horizontally elongated hole 15 formed in the support wall 14. A pivot pin 24 for the pedal 7, which is inserted through window holes 18 formed at both ends of the support wall 14, is provided protruding from the inner surface of the side wall 17.

A support stand 20 for the pedal shaft 6 is mounted on the rear bottom wall 19 of the bottom frame 5.
As shown in FIG. 7, a pair of elastic pieces 21 are provided at the upper end of the support 20 to allow the pedal shaft 6 to pass therethrough.

As shown in FIG. 3, the pedal shaft 6 is made of a metal wire of an appropriate diameter, and has a bent piece 6b bent toward the right side in FIG. 3 at the rear end of the straight portion 6a, and a bent piece 6b bent toward the right side in FIG. An inclined bent piece 6c is bent toward the opposite side of the bent piece 6b, and the tip thereof faces upward, and a tip piece 6d is provided at the tip of the bent piece 6c, which is bent toward the front of the bottom frame 5. The rear end of the linear portion 6a is rotatably held on the support base 20, and the tip is attached to the bottom frame 5 with the tip supported by the support recess 16.

The horizontally elongated hole provided in the bottom frame 5 is provided to facilitate the passage of the tip of the pedal 7 into and out of the bottom frame 5.

When the pedal shaft 6 attached to the bottom frame 5 is rotated, the support portions at both ends of the straight portion 6a serve as fulcrums when rotating, and when the tip piece 6d protruding from the front of the bottom frame 5 is rotated and lowered around the straight portion 6a, the pedal shaft 6 is rotated. , the pedal shaft 6 rotates around the axis of the straight part 6a, and the pedal shaft 6 rotates around the axis of the straight part 6a, and
The tip of the will rotate upwards in the opposite direction.

The pedal 7 is provided with mounting pieces 22 at the rear of both sides, and has a side hole 1.
By fitting the pin 24 into the through hole 21.3 of the mounting piece 22 inserted into the bottom frame 8 from the front, the pin 24 is inserted into the front part of the bottom frame 5.
It is installed so that it can freely swing up and down around the center.

As shown in FIGS. 3 and 6, the pedal 7 attached to the front surface of the bottom frame 5 has a central portion of its lower surface exactly resting on the tip piece 6d, and when the pedal is depressed, the tip piece 6d is moved to the straight portion 6a. The pedal shaft 6 is rotated and lowered around the center to give rotation to the pedal shaft 6.

The lower end of a push-up bar 8 disposed vertically at the rear of the container body 1 is pivotally connected to the tip of the bent piece 6d of the pedal shaft 6, and the rotation of the pedal shaft 6 is coupled to the vertical movement of the push-up bar 8. The lid 4 is then opened and closed.

The pedal structure of this invention has the above-mentioned configuration, and in order to use it as a dust pot, it is sufficient to incorporate the inner container into the case body 1, and when the pedal 7 is depressed, the pedal shaft 6 is connected to the support base 20. It rotates around both ends of the straight part 6a supported by the support recess 16, and while the tip piece 6d rotates downward, the bent piece 6b rotates upward, and the push-up rod 8 rises. Since the lid hinge 3 is pushed up, the lid 4 attached to the lid hinge 3 rotates upward around the mounting pin to the open position, and the upper end of the container body 1 is opened downward, preventing dust from entering the inner container 1. You can make an investment.

Further, in this state, the inner container 1 can also be taken out.

When the pedal 7 is released, the lid 7 is lifted by its own weight and the container body 1
The user falls down and closes the upper end opening, and the push-up bar 8 is pushed down, so the pedal shaft 6 rotates in the opposite direction to that when traveling on the road, and the pedal 7 returns to the raised position.

As described above, according to this invention, when the pedal is depressed, the pedal shaft rotates, and this rotational movement is converted into the vertical movement of the lid push-up bar. It only needs to be supported by the front support recess and the rear support base, which greatly simplifies the pedal shaft support structure, and since rotational movement is converted into the opening/closing movement of the lid, opening/closing operations can be performed with a small stepping force. This makes it easier to use.

In addition, since it uses rotational motion, it is possible to achieve opening and closing movements with a sharp stroke with just a slight step down.
