Abstract

An apparatus for releasably securing an article on a flat surface. The article is supported at its bottom surface by a first upper supporting surface of a supporting plate; that has at least one first through hole, and a blocking portion in a first lower surface. A vacuum sucker is provided for releasably attaching to the flat surface and is provided with a second through hole on a second lower surface and being adapted to be blocked by the blocking portion of the supporting plate. At least one telescopic guiding assembly including a spindle secured at a first lower end to the second upper supporting surface of the sucker body and having an upper portion which extends upwardly from the first lower end through the first hole beyond the first upper supporting surface of the supporting plate, and an outer tube secured at a second lower end thereof to the first upper supporting surface of the supporting plate around the first through hole and extending upwardly from the second lower end thereof to surround the upper portion of the spindle extending beyond the first upper supporting surface. The spindle telescopically moves in and relative to the first through hole and the outer tube by a force in an upright direction.

An apparatus for releasably securing an article having a bottom surface on a flat surface, comprising:

a supporting plate for the article, having a first upper supporting surface, a first lower surface, and at least one first through hole, said first upper supporting surface being adapted to be attached to the bottom surface of the article for supporting the article thereon, said first lower surface having a blocking portion;
vacuum sucking means for releasably attaching to the flat surface, including a sucker body having a second upper supporting surface and a second lower surface, said sucker body being provided with a second through hole which extends through the thickness of said sucker body from said second lower surface to said second upper supporting surface and is adapted to be blocked by said blocking portion of said first lower surface of said supporting plate;
and
at least one telescopic guiding assembly, including a spindle and an outer tube, said spindle being secured at a first lower end thereof to said second upper supporting surface of said sucker body and having an upper portion which extends upwardly from said first lower end thereof through said first through hole beyond said first upper supporting surface of said supporting plate, said outer tube being secured at a second lower end thereof to said first upper supporting surface of said supporting plate around said first thorugh hole and extending upwardly from said second lower end thereof to surround said upper portion of said spindle extending beyond said first upper supporting surface, said spindle having a diameter slightly smaller than the inner diameter of said first through hole and than the inner diameter of said outer tube so that said spindle is permitted to be driven to telescopically move in and relative to said first through hole and said outer tube by a force in an upright direction;
whereby, when said apparatus is located upon the flat surface with the article being securely attached on said first upper supporting surface of said supporting plate, the weight of the article will force said supporting plate to move downwardly to allow said blocking portion of said first lower surface of said supporting plate to block said second through hole of said sucker body with substantially all of the length of said spindle being telescopically inserted into said outer tube, so that said sucker body may suctorially secure to the flat surface under the pressure created by the weight of the article;
and when the article is upwardly lifted up, said supporting plate is also lifted up to allow said blocking portion to disengage said second through hole so that the suctorial force of said sucker body is removed.

An apparatus for releasably securing an article having a bottom surface on a flat surface, comprising:

a supporting plate for the article, having a first upper supporting surface, a first lower surface, a plug member located centrally on said first lower surface and extending downwardly from said first lower surface, an outer guiding tube extending downwardly from said first lower surface and surrounding said plug member, and a first through hole disposed in the area of said supporting plate between said plug member and said outer guiding tube, said first upper supporting surface being adapted to be attached to said bottom surface of the article for supporting the article thereon, said plug member having a blocking portion at a lower distal end thereof;
and
vacuum sucking means for releasably attaching to the flat surface, including a sucker body having a second upper supporting surface, a second through hole disposed centrally of said sucker body and formed to be adapted to be blocked by said blocking portion of said plug member when said apparatus is located upon the flat surface and the article is loaded by said supporting surface, and an inner guiding tube extending upwardly from said second upper supporting surface and surrounding said second through hole, both of the inner diameters of said outer and inner guiding tubes being larger than the peripheral dimension of said plug member, the outer diameter of said inner guiding tube being substantially equal to the inner diameter of said outer guiding tube so that said inner guiding tube may be telescopically inserted into said outer guiding tube with said plug member inserting into the interior of said inner guiding tube to prepare to block said second through hole and with said first and second through holes achieving therebetween an atmospheric communication which will be shut off by said blocking portion of said plug member when the weight of the article is enabled to be applied to said supporting plate which then moves downwardly to allow said blocking portion of said plug member to sealingly block said second through hole with substantially all of the length of said inner guiding tube inserting into said outer guiding tube;
whereby, when said apparatus is located upon the flat surface with the article being securely attached on said first upper supporting surface of said supporting plate, the weight of the article will force said supporting plate to move downwardly to allow said blocking portion of said plug member to sealingly block said second through hole of said sucker body with substantially all of the length of said inner guiding tube being telescopically inserted into said outer guiding tube, so that said sucker body may suctorially secure to the flat surface under the pressure created by the weight of the article;
and when the article is upwardly lifted up, said supporting plate is also lifted up to allow said blocking portion to disengage said second through hole so that said second through hole is in communication with the atmosphere through said first through hole so that the suctorial force of said sucker body is removed.
