Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an auxiliary operating device for a hand grease gun,
In particular, the present invention relates to an auxiliary operating device for a hand grease gun, which is suitable for preventing falling during the operation of sending out oil and fat.

[Prior Art] Conventionally, as described in, for example, Japanese Utility Model Laid-Open No. 62-73195, a main body for storing highly viscous oil such as grease, and an operation lever whose one end is rotatably supported by the main body, A support base provided on a hand grease gun including the conduit for discharging the oil and fat when the operation lever is operated, mounted on the main body, and arranged on a fixed body such as a floor, and an upper part of the support base. Auxiliary operating device for hand grease gun having a reinforcing lever rotatably mounted to engage with the operating lever, a pedal fixed to the reinforcing lever, and an elastic body for applying a restoring force to the reinforcing lever. Is proposed.

[Problems to be Solved by the Invention] Generally, in a hand grease gun, a large length of force is required to send out oil and fat from the main body, so that the operating lever requires a predetermined length dimension. In addition, a large stroke of the operating lever is required to quickly send out the oil and fat. Accordingly, in the auxiliary operating device for the hand grease gun, since the auxiliary lever engages with the above-mentioned operating lever, the length and stroke of the auxiliary lever are considerably large. And in the above-mentioned prior art, the pedal provided at the other end of the reinforcing lever is
The pedal is pushed up to a relatively high position when the auxiliary lever is returned because it is separated from the end provided with the rotation fulcrum by the entire length of the reinforcing lever. Therefore, there is a safety problem that the auxiliary operating device is likely to fall when the pedal is pushed down at this high position.

The present invention has been made in view of the actual situation in the related art, and an object thereof is to provide an auxiliary operating device for a hand grease gun capable of preventing a fall when the pedal is pushed down by a foot. .

[Means for Solving the Problems] In order to achieve this object, the present invention provides a body for storing oil and fat, an operation lever whose one end is rotatably supported by the body, and the oil and fat when the operation lever is operated. A support base provided on a hand grease gun including a conduit for discharging the oil, and mounted on the main body and arranged on a fixed body, and an auxiliary member rotatably mounted on the top of the support base to engage with the operation lever. A hand grease gun that has a lever, a pedal fixed to the auxiliary lever, and an elastic body that gives a restoring force to the auxiliary lever, and operates the operation lever via the auxiliary lever by pushing down the pedal. In the operating device, the pedal is provided so as to project to a side portion of the auxiliary lever, and the side portion of the support base has a projecting portion that receives a pushing-down force of the pedal. is there.

[Operation] Since the present invention is configured as described above, the support base mounted on the body of the hand grease gun is arranged on a fixed body such as a floor, and an auxiliary lever attached to the upper part of the support base is installed. With it engaged with the operating lever of the hand grease gun,
When the pedal provided on the side portion of the auxiliary lever is pushed down by the foot, the auxiliary lever rotates downward, and accordingly, the operation lever is actuated, so that the oil and fat in the main body is discharged through the conduit. At this time, of the downward force applied to the pedal,
A component in a direction orthogonal to the longitudinal direction of the auxiliary lever, that is, a force that causes the auxiliary operating device to fall sideways is received by the protrusion. As a result, the height of the pedal when the auxiliary lever is returned can be lowered relatively downward to improve the stability, so that the fall of the pedal when pushing it down can be prevented.

[Embodiment] Hereinafter, an auxiliary operating device for a hand grease gun of the present invention will be described with reference to the drawings.

1 is a perspective view showing an embodiment of an auxiliary operating device for a hand grease gun of the present invention.

A hand grease gun 1 shown in this figure includes a main body 3 for accommodating a highly viscous oil and fat cartridge 2 such as grease, an operation lever 4 having one end rotatably supported by the main body 3,
It includes a conduit 5 for discharging oil and fat in the cartridge 2 when the operating lever 4 is operated.

The auxiliary operating device 6 of the present invention is mounted on the main body 3 through the metal fittings 7, and is mounted on a fixed body such as a floor (not shown). Auxiliary lever 10 that is movably mounted and that engages with the side separated from the rotation fulcrum of the operating lever 4 via a connecting portion 9, and an elastic body 11 that applies an upward restoring force to this auxiliary lever 10.
And have. On the side part of the above-mentioned auxiliary lever 10,
A pedal 12 is provided. Further, the support base 8 described above is
A plate 13 that is arranged between the end of the main body 3 and the fixed body and has a stopper 7 on the top, and a first protrusion that is provided on the side of the plate 13 and that receives the pressing force of the pedal 12. 14
And a pair of leg portions 15 which are erected obliquely from both side portions of the plate body 13, another pair of leg portions 16 which support an intermediate portion of the pair of leg portions 15, and the pair of leg portions 16 are on both sides. A plate body 17 that is respectively erected on each of the parts and that is disposed between the intermediate portion of the main body 3 and the fixed body, and that is provided on the side portion of the plate body 17,
A second protrusion 18 that receives the pushing force of the pedal 12;
The upper ends of the pair of legs 15 are connected to each other above the main body 3 and are composed of a pin 19 for holding the elastic body 11. The auxiliary lever 10 is composed of a pair of levers 20 and 21 which are connected to each other, one end of which is rotatably supported via a pin 19, and the connecting portion 9 and the pedal 12 are arranged on the other end side.

In this embodiment, the elastic body 11 allows the auxiliary lever 1
0 is rotated in the direction indicated by arrow 23 in the figure, and the pedal 12 is pushed up to a predetermined height, the pedal 12
When the foot is pushed down, the auxiliary lever 10 rotates in the direction of arrow 22 in the figure. Along with this, the operating lever 4 engaged with the auxiliary lever 10 via the connecting portion 9 is actuated in the direction of arrow 22 in the figure, so that the oil and fat in the cartridge 2 of the main body 3 is discharged from the conduit 5. At this time, of the downward force applied to the pedal 12, the component in the direction orthogonal to the longitudinal direction of the auxiliary lever 10, that is, the force that attempts to tip the auxiliary operating device 6 to the side is located below the pedal 12. First to do
Received by the protrusion 14 and the second protrusion 18.

In the embodiment configured as described above, the pedal 12 provided on the side portion of the auxiliary lever 10 is arranged at a position closer to the pin 19 of the rotation fulcrum than the end portion of the auxiliary lever 10 in the longitudinal direction. Since the height of the pedal 12 when the auxiliary lever 10 is returned is lower than that of the pedal in which the auxiliary operating device 6 is arranged, the stability of the auxiliary operating device 6 can be improved.

[Effects of the Invention] Since the present invention is configured as described above, the height of the pedal when the auxiliary lever is returned can be lowered relatively downward to improve the stability. This has the effect of preventing the auxiliary operating device from falling when it is pushed down.
