Abstract
Description
- 1. Field of the Invention
- The present invention relates generally to a device for holding and moving stones with suction forces, and in particular to a suction device that allows for minute distance adjustment, fixed-step advancing, and orientation adjustment between stone workpieces.
- 2. The Related Art
- It is common in stone industry or construction industry to move and properly position heavy stone workpieces, such as marble blocks. This is usually done with suction device that applies a suction force to the stone workpieces for picking up and conveying the stone workpieces.
- However, the conventional devices can only roughly position the suction-retained stone at an approximately location, and location adjustment is usually done manually with visual inspection. This makes it very difficult to precisely position the stones, especially to provide a precise gap between two stones or two stone slabs. Imprecise positioning of stones may deteriorate appearance of a finished job and even causes property damage and casualty.
- A distance adjustable suction device is available, which is shown in
FIG. 1 of the attached drawings. The suction device, generally designated withreference numeral 1, comprises first andsecond suction cups toothed racks 12 extending therebetween. First ends of theracks 12 are fixed to thefirst suction cup 10, while the other ends form teeth. Arotary handle 13 is rotatably mounted to thesecond suction cup 11 and comprisesratchet pinions 131 rotatably supported thereon. Theratchet pinions 131 matingly engage the teeth of theracks 12, respectively. By repeatedly and reciprocally rotating the handle with respect to thesecond suction cup 11, theratchet pinions 131 that engage theracks 12 drive theracks 12 to move thefirst suction cup 10 with respect to thesecond suction cup 11 in a step by step manner. Thus, the distance between the first andsecond suction cups - However, since the distance moved by a step of the
racks 12 induced by thehandle 13 is determined by the pitch of the teeth of theracks 12. It is not possible to do distance adjustment of a fraction of one step of theracks 12. Thus fine adjustment is in general very difficult, if not impossible. - Further, the arrangement of the
racks 12, which are generally rigid, between the first and second suction cups makes it not possible for applications where the first and second suction cups are attached to stones that are at different levels, or that are of an inclined spatial relationship. - Thus, it is desired to have a suction device for stones that overcomes the above-discussed problems of the conventional devices.
- Thus, the present invention is aimed to provide a suction device that can do fine adjustment of distance between two heavy articles that are suction-retained by suction cups of the suction device, while still allows the heavy articles to be moved with respect to each other in a step by step manner.
- Another objective of the present invention is to provide a suction device that allows two heavy articles that are suction-retained by suction cups of the suction device to be oriented in an angle with respect to each other for adjusting orientation between the articles.
- To achieve the above objectives, in accordance with the present invention, a suction device is provided, comprising two suction cups and a controlling mechanism connected between the suction cups. Each suction cup comprises a rotatable mounting block. The controlling mechanism comprises a main body forming a knuckle joint with the mounting block of one suction cup and defines a channel movably receiving a rack that threadingly engages a internally-threaded cylinder that forms a knuckle with the mounting block of the other suction cup. Thus, the suction cups are each rotatable about two axes with respect to the main body and are linear movable with respect to each other. Further, the threading engagement between the cylinder and the rack allows for minute adjustment between linear distance between the suction cups.

Theconnection member 43 is sized and shaped to fit into the space between thelugs 320 of themounting block 32 of thesecond suction cup 3, and defines atransverse bore 430 for the extension of thepivot pin 321, whereby themounting block 32, thepivot pin 321, and theconnection member 43 together form a knuckle joint between thesecond suction cup 3 and themain body 40 of the controlling mechanism 4. Te knuckle joint allows thesecond suction cup 3 to rotate or incline with respect to themain body 40 of the controlling mechanism 4. - An opposite end of the
rack 42 forms a threadedsection 420, which extends beyond themain body 40 through an opposite opening of thechannel 41. Amovable cylinder 44 has a first hexagonal orpolygonal section 440 that defines an internally threadedbore 442 engageable with the threadedsection 420 of therack 42, and a second, preferably cylindrical,section 441. - A
ratchet wrench 5 or similar tool selectively engages thepolygonal section 440 of themovable cylinder 44, whereby manually operating thewrench 5 causes themovable cylinder 44 to move axially with respect to therack 42. - The
second section 441 of themovable cylinder 44 is coupled to aconnection block 45, which has an extension (not labeled) sized and shaped to fit between thelugs 220 of themounting block 22. The extension defines abore 450 aligned with the holes defined in thelugs 220 for the extension of thepivot pin 221, thereby forming a knuckle joint between therack 42 and thefirst suction cup 2. This allows thefirst suction cup 2 to be rotatable with respect to the controlling mechanism 4. - The

FIGS. 5-7 , the operation of the suction device will be explained. The first andsecond suction cups - The mounting
block support disk suction cup suction cup main body 40 of the suction device, about an axis that are substantially normal to thesupport disk - The suction cups 2, 3 are rotatably attached to the
main body 40 of the controlling mechanism 4 by the knuckle joints thereof. This allows the stone blocks that are carried by thesuction cups support disks main body 40 of the controlling mechanism 4. - Further, the
first suction cup 2, together with the stone carried thereby, is allowed to do translation with respect to thesecond suction cup 3 and the stone carried by thesecond suction cup 3 by means of the movement of therack 42 caused by the manual rotation of therotary handle 46. With a combination of the above described rotation about the axis normal to the support disk, rotation about the axis parallel to the support disk, and translation, the spatial relationship between the two stone blocks carried by thesuction cups - In addition, the distance between the two stone blocks can be adjusted in a minute advance manner. This is done with the threading engagement between the
movable cylinder 44 and therack 42 by manual rotation of themovable cylinder 44 with thewrench 5. - Further, with the foot blocks 480, 490 properly positioned on the stone blocks, the adjustment blots 48, 49 can be used to securely hold the suction device on the stone blocks to be adjusted.
