Telescopic safety shield for machine tool
View Patent ↗A telescopic safety shield device includes a carrier movably engaged onto a platform and having one or more guideways tilted relative to the platform, a tool rest movably engaged onto the guideways and moveable inclinedly relative to the carrier and the platform, and a telescopic shielding device having two or more casing members coupled between the platform and the tool rest for shielding the area between the platform and the tool rest, the casing members are pivotally coupled to the platform and the tool rest for allowing the casing members to be pivoted relative to the platform and the tool rest respectively and for preventing dirt or contaminant from entering into the areas between the platform and the tool rest.
1. A telescopic safety shield device comprising:
a platform,
a carrier movably engaged onto said platform, and including at least one guideway disposed on an upper portion of said carrier and tilted relative to said platform,
a tool rest movably engaged onto said at least one guideway of said carrier and moveable inclinedly relative to said carrier and said platform,
a telescopic shielding device coupled between said platform and said tool rest and for shielding and covering an area between said platform and said tool rest, said telescopic shielding device including a first casing member and a second casing member,
a first pivot coupling device pivotally coupling said first casing member of said telescopic shielding device to said platform, and
a second pivot coupling device pivotally coupling said second casing member of said telescopic shielding device to said tool rest for allowing said first casing member and said second casing member of said telescopic shielding device to be pivoted relative to said platform and said tool rest respectively.
2. The telescopic safety shield device as claimed in claim 1 , wherein said first pivot coupling device includes at least one panel attached to said first casing member, and at least one flap pivotally coupled to said at least one panel with a pivot shaft for allowing said at least one flap to be pivoted relative to said at least one panel, said at least one flap is attached to said platform for allowing said first casing member to be pivoted relative to said platform.
3. The telescopic safety shield device as claimed in claim 2 , wherein said platform includes a beam pivotally coupled to said at least one flap of said first pivot coupling device.
4. The telescopic safety shield device as claimed in claim 1 , wherein said telescopic shielding device includes at least one third casing member slidably coupled between said first casing member and said second casing member.
5. The telescopic safety shield device as claimed in claim 4 , wherein said at least one third casing member includes a scraping device slidably engaged with said first casing member for wiping dirt off said first casing member.
6. The telescopic safety shield device as claimed in claim 4 , wherein said second casing member includes a scraping device slidably engaged with said at least one third casing member for wiping dirt off said at least one third casing member.
7. The telescopic safety shield device as claimed in claim 1 , wherein said second pivot coupling device includes at least one panel attached to said second casing member, and at least one flap pivotally coupled to said at least one panel with a pivot shaft for allowing said at least one flap to be pivoted relative to said at least one panel, said at least one flap is attached to said tool rest for allowing said second casing member to be pivoted relative to said tool rest.
8. The telescopic safety shield device as claimed in claim 7 , wherein said tool rest includes a bottom pivotally coupled to said at least one flap of said first pivot coupling device.
9. The telescopic safety shield device as claimed in claim 1 , wherein said carrier includes a safety covering device attached to said carrier for shielding and covering an area between said tool rest and said carrier.
10. The telescopic safety shield device as claimed in claim 9 , wherein said safety covering device includes a frame secured to said carrier and a hood attached to said frame and located above said tool rest for shielding an upper portion of said tool rest.
11. The telescopic safety shield device as claimed in claim 10 , wherein said hood is secured to said frame with at least one bar.
12. The telescopic safety shield device as claimed in claim 10 , wherein said safety covering device includes a cover attached to said tool rest, and a scraping device attached to said hood and engaged with said cover of said tool rest and for scraping a dirt off said cover of said tool rest.
13. The telescopic safety shield device as claimed in claim 12 , wherein said scraping device includes a plate secured to said hood and a wiper member engaged with said cover of said tool rest.
14. The telescopic safety shield device as claimed in claim 1 , wherein said carrier includes a covering device secured to said carrier for shielding and covering an area between said platform and said carrier.
15. The telescopic safety shield device as claimed in claim 1 , wherein said first casing member and said second casing member each include a spacer for spacing purposes.
