Hydraulic carpet kicker

Abstract

A hydraulic carpet kicker, comprising: a) a housing having internally a receiving chamber, a handle and a switch being formed at the top of the housing; b) an oil storage tank attached to the housing for storing the liquid to provide the oil hydraulic pressure; c) an oil hydraulic cylinder disposed at the bottom of the oil storage tank and having a front cylinder wall and a rear cylinder wall, a piston and a piston rod being positioned within the oil hydraulic cylinder, the external end of the piston rod extending through the front cylinder wall to be connected to a kicking unit, the internal wall of the piston and the rear cylinder wall defining an oil pressure action area, a spring being interposed between the external wall of the piston and the front cylinder wall; and d) an oil pressure unit having a motor and a pump within the receiving chamber, an oil suction pipe being interposed between the pump and the oil storage tank, an oil inlet pipe being positioned between the pump the oil pressure action area, the bottom of an oil return pipe being connected to the oil pressure action area, the top thereof being attached to the oil storage tank, an return oil release knob being disposed at the top of the oil storage tank for controlling the on / off state thereof. In this way, a simple structure and a convenient operation are achieved.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a carpet kicker, and more particularly to a carpet kicker that employs the oil hydraulic pressure as power source to directly drive a kicking unit for pushing forward the free end of a carpet when the carpet is laid. In retracting, a spring force is employed to return the kicking unit in its original position.[0003]2. Description of the Related Art[0004]Carpets are commonly laid on the floor of our home or office and give us an indoor warm and comfortable feeling. However, carpets must be laid evenly and smoothly on the floor, or else the carpets will be uneven, not only affecting its appearance, but also creating a problem of stumbling people easily.[0005]If a large carpet is laid, a user usually cannot pull and spread the thick and heavy carpet evenly by hands, and thus a carpet kicker is needed for the job.[0006]Referring to FIG. 1, a prior art carpet kicker 70 is used to hold a free end of a...

AI Technical Summary

Benefits of technology

[0012]An object of the invention is to eliminate the above-mentioned drawbacks and to provide a hydraulic carpet kicker that includes a built-in oil hydraulic system. The oil hydraulic system provides an oil hydraulic pressure serving as power to directly drive the kicking unit to move forward the free end of the carpet. Meanwhile, the whole apparatus stays unmoved except that the kicking unit holds the carpet to move toward the side wall. In this way, a convenient human / machine operation interface is achieved. Moreover, the carpet can be rapidly spread in a flat position.

Problems solved by technology

However, carpets must be laid evenly and smoothly on the floor, or else the carpets will be uneven, not only affecting its appearance, but also creating a problem of stumbling people easily.

However, this method requires a lot of time and effort.

Meanwhile, a long-term use of the paint cover to push against the cushion 75 will cause vocational injuries.

1. Since the piston is driven pneumatically to move the piston rod 85, therefore an external air compressor 90 is needed to supply air pressure which is inconvenient to users. In other words, users have to carry a heavy and expensive air compressor 90 for the use of the carpet kicker 80, and it thus makes the application impractical. Although people tried to replace the pneumatic way with the hydraulic way, a practical hydraulic carpet kicker is still not developed due to the structure and features in spreading the carpet.

2. Since the interval D between a pin board 60 for fixing the carpet 62 and a skirting board 64 at the wall is only 5 mm˜10 mm, and the design does not allow the hook 861 to be installed within the interval D, and it often makes the carpet kicker 80 useless. If the interval D of the pin board 60 is increased to allow the installation of the hook 861, the carpet will produce creases easily and affect the appearance of the carpet adversely.

3. Moreover, the kicking unit 84 and the housing 83 are attached to each other and not mounted on the piston rod 85. The carpet kicker 80 uses the hooking rod 86 to hook a fixed end of the pin board 60, and then the piston board 85 is moved back and forth to pull components such as the housing 83, handle 82 and kicking unit 84 indicated by dotted lines in the figure to move towards the wall synchronously. Furthermore, the method of using the protruding pin 841 to drive and pull the carpet 62 towards the pin board 60 is not too practical, because all of the actions for hooking and pulling the carpet 62 are centralized at the hook 861, and the pin board 60 is lifted by the hook 861 when the carpet 62 has not been pulled evenly yet. Moreover, the kicking unit 84 is not driven by the piston rod 85. Therefore, the kicking unit 84 loses the pulling force when the hooking rod 86 is detached. As a result, an independent application is not possible so that this structure requires further improvements.
