IES86596B2 - Clamping device for lifting and lying block - Google Patents

Abstract

The present invention relates to a clamping device for carrying concrete blocks and consists of two jaws (1,2) with serrated teeth. The dome nut (4) when removed from the threaded shaft adjusts the dimension of the block from six to four inches. The comfort grip handle (5) and plate with boreholes is linked to the slide shaft that activates the pressure to the block's weight. As the handle is lifted the two jaws close together grasping the block and the gripping force is directly proportional to the weight, thereby allowing lifting or manoeuvring into a precise position. The advantage of the invention is that the support assembly allows for a strong construction with no mechanical parts. <Figure 1a>

Description

Title Clamping device for lifting and laying blocks.

Field of Invention The present invention relates to the field of handling equipment. In particular to a tool designed for lifting and laying blocks. This product is designed for the building trade.

Background The invention relates to the field of masonry tools and its subject is a clamping device for concrete blocks. The clamp is in accordance with the invention essentially allowing of easy handling, moving and laying of concrete blocks to a precise position.

The block clamp is constructed of heavy wall mild steel plate which can grab a 6 inch or a 4 inch Block. The change in the size of the block dimension is by the lever handle adjustment, In placing the jaws of the block clamp at either side of the block, the lifting force closes the clamp at both sides, pressurising with block’s own weight. By placing the block in the position required, it releases the block’s own weight also releasing the block clamp. For a safer lift shown on the diagram, the serrated teeth give a better grip on the surface of either side of the block with a very firm hold. s86596 The present invention is a clamping device, with serrated jaws at each side of the clamp, to have a firm grip at either side of the masonry block. It allows a person to carry, lift, and deposit blocks to a precise laying precision.

The handle with a comfort grip and plate with bore holes to suit the slide shafts. The double bore holes are to suit the changeover of the block dimension. The plate is slightly curved to suit the slide shafts and prevents the handle from choking in use, As the handle is lifted, the two arms close together, grasping the block, with the block’s own weight, can thereby be lifted or maneuverer into position.

The block clamp is constructed of heavy wall mild steel plate, and will withstand heavy work conditions.

The advantage of the invention is that it is constructed with no mechanical parts, as well as maintenance free.

The main purpose of this product is lifting and handling of masonry blocks. its benefit is simplifying the laying of blocks, and since the clamping device is to be regarded as an extension of the arms of the worker, it makes tire operation of laying blocks easier on the spine and knees Its small, portable, and affordable, easily stored, a basic hand tool to suit block layers.

Brief Description The present invention is in the field of handling equipment and more particularly relates to a clamping device for the lifting of masonry blocks. The purpose of the present invention is to provide a clamping device, with the serrated jaws at each side of the clamp, to have a firm grip at either side of the masonry block, it allows a person to carry, lift, and deposit blocks to a precise precision. The clamping device has the advantage of a simplified clamp and holding structure, which is safe, secure and reliable.

At present, block layers and other personnel working on building sites typically manually handle a block by gripping it with both hands and carrying it to a particular location. This can cause fingers to be pinched or squeezed and despite wearing gloves come abrasions.

The invention will be more clearly understood from the following description and will be accompanied with reference and drawings.

Detailed Description Of The Drawings The present invention relates to a clamping device for carrying concrete blocks and consists of two jaws (1&2) with serrated teeth. The dome nut (4) when removed from the threaded shaft adjusts the dimension of the block from six to four inch. The comfort grip handle (5) and plate with boreholes is linked to the slide shaft that activates the pressure to the block’s weight.

As the handle is lifted the two jaws close together grasping the block and the gripping force is directly proportional to the weight, thereby lifting or manoeuvring into a precise position, thus making the device very simple.

The advantage of the invention is that the support assembly allows for a strong construction with no mechanical parts.

Referring to the drawings and initially figure la the clamping device will now be described in detail.

Number 1 in Fig lb shows an individual component of the gripping device in a disassembled condition. It comprises of the section of the gripping jaw, the scissors action plate with the centre bolt hole to suit the bolt and nut 3 fig Id and the slide shaft on top. The top ring plate on the slide shaft prevents the handle number 5 fig If from becoming dislocated from the unit. The bottom thumb on the slide shaft is used as a down stop.

Number 2 in fig lc shows the other section of the gripping jaw with the serrated teeth, the scissors action plate with the centre bolt hole to suit the bolt and nut 3 fig Id and the slide shaft on top. On the top of the slide shaft is the threaded section to suit the dome head bolt 4 fig le., for the changeover of the block dimension. The threaded bolt is rigidly connected with this threaded nut.

Number 5 fig If shows the handle with a comfort grip and plate with bore holes to suit the slide shafts. The double bore holes are to suit the changeover of the block dimension. The plate is slightly curved to suit the slide shafts and prevents the handle from choking in use.

As the handle is lifted, the two arms close together, grasping the block, with the block’s own weight, can thereby be lifted or maneuverer into position.

At present, block layers and other personnel working on building sites typically handle a block by gripping it with both hands and carrying it to a particular location. This can cause fingers to be pinched or squeezed and despite wearing gloves come abrasions. The clamping device with its strong and secure grip to the block will ensure no contact to hands, so the risk of injury is impossible.

Claims (4)

Claims

1. A clamping device for use in lifting and carrying concrete blocks. The devise comprises of a handle with two opposed gripping jaws that sits in a downward position. When manoeuvring the clamp over the block in a downward position it will locate itself on either side of the block. When the clamp is lifted the handle will slide on both shafts and grip the block with the scissor action motion.

2. A clamping device for use in lifting and carrying concrete blocks claim the handle plate is slightly curved to suit the slide shafts and support the handle. The double holes to suit changeover of the block dimension. The dome nut when removed from the threaded shaft, and relocated on the threaded shaft, adjusts the dimension from the first hole to the second hole on the handle, from six inch block to four inch block. The handle is curved to suit the slide shaft and the top ring plate on the slide shaft prevents the handle from becoming dislocated from the unit. The bottom thumb on the slide shaft is used as a down stop.

3. A clamping device for use in lifting and carrying concrete blocks claim the serrated teeth gives a securer grip to the masonry building block when lifted with clamp. There is no movement while in a secure position, and while a person is in mobile from A-B

4. A clamping device as substantially hereinbefore describes with reference to the accompanying description and/or drawings
