RU2080900C1 - Foot support of device for man moving over vertical rope - Google Patents

Abstract

FIELD: devices for man moving over vertical ropes. SUBSTANCE: the essence of the invention consists in rigid fixing of feet in foot supports, fastening of shoes to supports without help by hands. Rigid fixing becomes possible due to the fact that heel of operator's working shoes is pressed to support shaft by flexible plate-type hold-down of counter regulated to the size of heel to preclude longitudinal motion of shoes on support with nose inclined downward. To prevent separation of shoe from support when lifting the upward motion bar by foot, the support has flexible plate-type hold-down of shoe cap (arch). Fastening of shoes to supports without help by hands is accomplished due to rounded-off free end of flexible plate-type hold-down. To move the foot onto support, it should be turned through 90 deg with respect to support, and inserted, first, heel into support between shaft and hold-down of counter, then, foot is to be turned to bring the shoe cap to under hold-down. Both hold-downs reliably hold the shoe on support. To release the shoe from support, reverse the procedure. EFFECT: higher efficiency. 3 cl, 2 dwg

Description

 The invention relates to devices for moving a person along a steel vertical rope without the help of hands, and more specifically to devices for fixing the legs on devices for moving along a vertical rope.

 A number of inventions are known for moving a person along a vertical rope, in which the shoes are attached to the foot supports either with fastening belts (A.S. NN 471272, 602199, 741894) or with an elastic plate bracket welded to the support (A.S. N 640746). The latter is taken as the closest analogue.

 Both of these methods of attaching shoes have significant drawbacks. In order to fasten the belts, it is necessary to bend to the foot supports, which is almost impossible due to the lift facing the person. Elastic metal staples make mounting shoes easier on the foot, but extremely unreliable. In both cases, the leg on the support remains movable, is not rigidly fixed, which makes it difficult to climb and lower the vertical rope.

 The objective of the invention is to provide a device for reliable and rigid fixation of shoes on the leg supports without the help of hands by means of adjustable size shoes (the size of the rise and the size of the heel) of elastic plate clamps.

 This task is achieved due to the fact that the platform of the support is equipped with a vertical carrier plate located on its inner side, the axis of the support is rigidly connected to the plate and the platform, and the fastening elements of the foot are elastic plate clamps made in the shape of the front and back parts of the shoe, and the clamps mounted on a carrier plate with the ability to move and fix. Oval holes are made in the carrier plate with a vertical arrangement of the major axis for the front clamp and horizontal for the back clamp, and clamp clamps are installed in the holes, and the free ends of the elastic plate clamps are bent to the outside.

 In FIG. 1 shows the proposed device, side view; in FIG. 2 is the same, top view, along arrows A and B shows oval holes in the carrier plate for fasteners of shoe-sized plate clips of the front and back (heel) adjustable in size.

 The device comprises an axis 1 of the support, fixed in the housing 2 of the movable rod 3. A rectangular platform 4 is welded to the lower edge of the vertical carrier plate 5, mounted on the axis of the support. The opposite end of the platform is attached from below to the axis 1. In front of the plate with two bolts 6 through the oval holes 7 of the plate 5, an elastic plate clip 8 is attached to the shoe front, behind the plate with two bolts 9 through the oval holes is attached an elastic plate clip 10 of the shoe back, pressing the heel to the axis 1 support.

 Oval holes of the plate 5 allow you to raise, lower and change the angle of inclination of the elastic clip of the front depending on the size of the shoe and the angle of elevation of the foot, as well as adjust the elastic clamp of the back to the size of the heel. The edges of the elastic clamps bent from the outside allow you to insert your foot into the support without using your hands and firmly fix it in the support. The leg itself cannot slip out from under the clamps; it can be removed from the foot support only by freeing the foot one by one from under each clamp separately. For this it is necessary, having turned the foot perpendicular to the support, first release the front of the shoe from the clip, and then pull the heel out from under the clip. To install the foot on the support, it is necessary, having deployed the foot perpendicular to the support, insert the heel between the back of the back and the axis of the support, after which, turning the foot, bring the foot under the front end clamp.

 When lifting and lowering, the clamps reliably hold the foot on the platform, allow you to remove your legs from the supports without using hands in any place of lifting and go to the ledge or niche of the wall, freed from the lift to perform the necessary work.
