Abstract
A rope clamping device for releasably clamping a rope in a substantially loop-shaped configuration adjacent to an end section thereof. The rope clamping device has a base member and a closure member hingely connected together. The base member and the closure member both have an elongated configuration and share a common longitudinal extent. The base member has a channel extending longitudinally therethrough. An abutment shoulder extends radially inside the channel. The base member also has a groove on its top surface. The closure member has a set of rope gripping elements projecting from its lower surface. The rope is adapted to be first tied into a knot adjacent to the end section and threaded though the channel with the knot abutting against the abutment shoulder. The rope is then adapted to be formed into a loop adjacent to the knot and a rope segment is adapted to be rested inside the groove.
In order to releasably lock the rope in the loop configuration, the closure member is then pivoted until the base member abuts against the closure member with the rope gripping means, preventing longitudinal displacement of the rope segment inside the groove.

Description
ROPE CLAMPING DEVICE
BACKGROUND
The present invention relates to the field of rope clamping devices and is particularly concerned with a rope clamping device for securing a rope in a loop configuration adjacent to a free end thereof.
Various situations exist wherein a rope needs to be releasably secured in a loop configuration adjacent to a free end of the rope. One example of such situation occurs in the field of car shelters wherein a sheet of substantially flexible material is mounted over a rigid tubular frame. The lower peripheral edges of the sheet often need to be secured to a lower supporting post that is part of the frame.
Conventionally, the lower peripheral edges of the sheet are provided with eyelets. Rope segments are thus threaded through the eyelet and wrapped around the supporting post. This procedure is both tedious and time consuming. Prior art rope clamping devices have proven to be either inefficient, unnecessarily complex or unergonomical.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide an improved adjustable rope clamping device. The rope clamping device in accordance with the present invention will secure a rope in a loop configuration adjacent to a free end of the rope.
The rope clamping device in accordance with the present invention allows a quick and ergonomical clamping and ~ unclamping action. The rope clamping device in accordance with the present invention will conform to conventional forms of manufacturing in order to be economically feasible.

DETAILED DESCRIPTION
Referring to figure 1, there is shown a rope clamping device 10 in accordance with an embodiment of the present invention. The rope clamping device 10 has a base member 12 and a closure member 13. The base member 12 and the closure member 13 share a common longitudinal extent.
The base member 12 comprises a substantially elongated body. The base member body has a pair opposite base member longitudinal end walls 14 and 16. The base member body also has a pair of opposite base member side walls 18 and 20. The base member body further has a base member lower surface 22 and a base member rope gripping top surface 24.
A rope receiving channel 26 extends longitudinally through the base member 12 from the base member end wall 14 to the base member end wall 16. The channel 26 extends along a longitudinal axis indicated by the reference letter A in figure 6.
An abutment shoulder 28 extends integrally and inwardly from the channel 26. The abutment shoulder 28 is positioned adjacent to the base member end wall 14.
The intersection of the opposite base member side walls 18 and 20 with the base member rope gripping top surface 24 defines a pair of corresponding opposite base member top surface longitudinal side edges 30 and 32.
An open top base member groove 34 is formed in the base member rope gripping top surface 24. The base member groove 34 extends from the base member end wall 14 to the base member end wall 16. The base member groove 34 is substantially centrally located relatively to the base member top surface longitudinal side edges 30 and 32.
The base member groove 34 has a substantially "U"-shaped cross-sectional configuration. The base member groove 34 has a groove bottom wall 36 and a pair of integrally extending and outwardly upstanding groove side walls 38.
A
A set of base member groove recesses collectively denoted by the reference numeral 40 are formed in the groove bottom wall 36. The base member groove recesses are longitudinally spaced along the groove bottom wall 36.
A set of locking pins collectively denoted by the reference numeral 42 extend integrally and substantially perpendicular to the base member rope gripping top surface 24.
The locking pins 42 are positioned adjacent to the base member top surface longitudinal side edge 32. Each locking pin 42 has a locking pin spacing section 44 extending integrally from the base member rope gripping top surface 24. Each locking pin 42 also has a locking pin gripping section 46 extending integrally from the locking pin spacing section 44. The locking pin gripping sections 46 have an external diameter which is greater than the external diameter of the locking pin spacing sections 44.
The base member 12 is hollowed-out, at least to some extent, by a pair of base member longitudinal cavities 48 and 50 formed in the base member rope gripping top surface 24. The base member longitudinal cavity 48 is formed adjacent to the base member top surface longitudinal side edge 32 while the base member longitudinal groove 50 is formed adjacent to the base member top surface longitudinal side edge 30.
The closure member 13 has a substantially elongated body.
The closure member body has a pair of opposite closure member longitudinal end walls 52 and 54. The closure member body also has a pair of opposite closure member side walls 56 and 58. The closure member body further has a closure member upper surface 60 and a closure member rope gripping lower surface 62. The intersection of the closure member side walls 56 and 58 with the closure member rope gripping lower surface 62 defines a pair of corresponding opposite closure member bottom surface longitudinal side edges 64 and 66.
A
A set of locking pins collectively denoted by the reference numeral 42 extend integrally and substantially perpendicular to the base member rope gripping top surface 24.
The locking pins 42 are positioned adjacent to the base member top surface longitudinal side edge 32. Each locking pin 42 has a locking pin spacing section 44 extending integrally from the base member rope gripping top surface 24. Each locking pin 42 also has a locking pin gripping section 46 extending integrally from the locking pin spacing section 44. The locking pin gripping sections 46 have an external diameter which is greater than the external diameter of the locking pin spacing sections 44.
The base member 12 is hollowed-out, at least to some extent, by a pair of base member longitudinal cavities 48 and 50 formed in the base member rope gripping top surface 24. The base member longitudinal cavity 48 is formed adjacent to the base member top surface longitudinal side edge 32 while the base member longitudinal groove 50 is formed adjacent to the base member top surface longitudinal side edge 30.
The closure member 13 has a substantially elongated body.
The closure member body has a pair of opposite closure member longitudinal end walls 52 and 54. The closure member body also has a pair of opposite closure member side walls 56 and 58. The closure member body further has a closure member upper surface 60 and a closure member rope gripping lower surface 62. The intersection of the closure member side walls 56 and 58 with the closure member rope gripping lower surface 62 defines a pair of corresponding opposite closure member bottom surface longitudinal side edges 64 and 66.
A
A hinge means hingely connects the base member top surface longitudinal side edge 30 to the closure member lower surface longitudinal side edge 66. In a preferred embodiment, the hinge means takes the form of a relatively thin hinge strip 68 made of substantially flexible material. The hinge strip 68 has a first longitudinal peripheral edge which merges with the base member top surface longitudinal side edge 30 and a second longitudinal peripheral edge which merges with the closure member lower surface longitudinal side edge 66.
The hinge strip 68 allows the base member 12 and the closure member 13 to be hingely pivoted relatively to one another between a rope clamping device opened configuration illustrated in figures 3, 4 and 5 and a rope clamping device closed configuration illustrated in figures 1, 2 and 7.
In the rope clamping device opened configuration, the closure member 13 is positioned aside relatively to the base member 12 whereas in the rope clamping device closed configuration the closure member 13 is in an overlying relationship relatively to the base member 12. A prehension tongue 7o extends integrally and substantially perpendicularly from the closure member side wall 56. The prehension tongue 70 is positioned adjacent to the closure member lower surface longitudinal side edge 64. The prehension tongue 70 is adapted to facilitate the rotation of the closure member 13 relatively to the base member 12.
A guiding protuberance 72 extends integrally and substantially perpendicular to the closure member rope gripping Lower surface 62. The guiding protuberance 72 has a substantially elongated configuration which corresponds substantially to the configuration of the base member longitudinal cavity 48. The guiding protuberance 72 is positioned adjacent to the closure member lower surface longitudinal side edge 64. The guiding protuberance 72 is configured and positioned so that when the rope clamping device is in its closed configuration, the guiding protuberance 72 will penetrate into the base member longitudinal cavity 48.
A set of pin receiving apertures 74 extend through the 5 closure member rope gripping lower surface 62. The pin receiving apertures 74 are positioned adjacent to the closure member lower surface longitudinal side edge 64. The pin receiving apertures 74 are configured and positioned so that when the rope clamping device 10 is in its closed position, the 10 pin receiving apertures 74 will receive the locking pins 42.
The pin receiving apertures 74 have a general configuration which corresponds substantially to the general configuration of the locking pins 42.
Each pin receiving aperture 74 thus has a section configured and sized to receive a corresponding locking pin spacing section 44 and a section configured and sized to receive a corresponding locking pin gripping section 46.
Each pin receiving aperture 74 is adapted to cooperate with a corresponding locking pin 42 in snappingly locking the rope clamping device 10 in its closed configuration.
A set of locking protuberances 76 extends integrally and outwardly from the closure member rope gripping lower surface 62. Each locking protuberance 76 has a generally block-shaped configuration defining a set of peripheral locking edges 78.
The intersection of the bass member groove recesses 40 with the groove bottom wall 36 defines a set of groove locking edges 80.
The locking protuberances 76 are positioned so that when the rope clamping device 10 is in its closed configuration, each locking protuberance 76 is in register with a corresponding base member groove recess 40.
In use, the rope clamping device 10 is adapted to clamp a rope such as the rope indicated by the reference numeral 82, in a loop configuration adjacent to a free end thereof.
In order to form a loop configuration such as the loop 84 of figure 7, a rope knot 86 is first tied in the rope 82 adjacent a first rope free end 88. A second rope free end 90 is then threaded into the first channel 26 from the base member 5 end wall 16 to the base member end wall 14. The rope 82 is then pulled through the first channel 26 until the knot 86 abuttingly contacts the abutment shoulder 28. The abutment shoulder 28 prevents the rope free end 88 from being pulled-out of the channel 26 through the aperture formed in the base 10 member end wall 14 by the channel 26.
The rope 82 is then bended in order to form the loop 84.
With the rope clamping device 10 in its opened configuration, a segment of the rope 82 which extends between the loop 84 and the second rope free end 90 is abuttingly rested inside the rope receiving channel 26. The closure member 13 is then pivoted about the hinge strips 68 in an overlying relationship relatively to the base member 12. The segment of the rope 82 which abuttingly rests atop the rope receiving channel 26 is thus sandwiched between the base member 12 and the closure member 13.
As illustrated in figure 7, the locking protuberances 76 are adapted to deform the rope 82 and to bias the rope 82 into the base member groove recesses 40. Consequently, the rope 82 will be engaged by the peripheral locking edges 78 of the locking protuberances 76 and the groove locking edges 80 of the base member groove recesses 40. The locking protuberances 76 and the base member groove recesses 40 are thus adapted to cooperate in preventing the longitudinal axial displacement of the segment of the rope 82 which is sandwiched between the base member 12 and the closure member 13.
It should be noted that although the rope clamping device 10 in accordance with the present invention is adapted to work with any suitable rope which fits into the first channel 26 and the base member groove 34, the rope clamping device 10 is A
The hinge strip 68 allows the base member 12 and the closure member 13 to be hingely pivoted relatively to one another between a rope clamping device opened configuration illustrated in figures 3, 4 and 5 and a rope clamping device closed configuration illustrated in figures 1, 2 and 7.
In the rope clamping device opened configuration, the closure member 13 is positioned aside relatively to the base member 12 whereas in the rope clamping device closed configuration the closure member 13 is in an overlying relationship relatively to the base member 12. A prehension tongue 7o extends integrally and substantially perpendicularly from the closure member side wall 56. The prehension tongue 70 is positioned adjacent to the closure member lower surface longitudinal side edge 64. The prehension tongue 70 is adapted to facilitate the rotation of the closure member 13 relatively to the base member 12.
A guiding protuberance 72 extends integrally and substantially perpendicular to the closure member rope gripping Lower surface 62. The guiding protuberance 72 has a substantially elongated configuration which corresponds substantially to the configuration of the base member longitudinal cavity 48. The guiding protuberance 72 is positioned adjacent to the closure member lower surface longitudinal side edge 64. The guiding protuberance 72 is configured and positioned so that when the rope clamping device is in its closed configuration, the guiding protuberance 72 will penetrate into the base member longitudinal cavity 48.
A set of pin receiving apertures 74 extend through the 5 closure member rope gripping lower surface 62. The pin receiving apertures 74 are positioned adjacent to the closure member lower surface longitudinal side edge 64. The pin receiving apertures 74 are configured and positioned so that when the rope clamping device 10 is in its closed position, the 10 pin receiving apertures 74 will receive the locking pins 42.
The pin receiving apertures 74 have a general configuration which corresponds substantially to the general configuration of the locking pins 42.
Each pin receiving aperture 74 thus has a section configured and sized to receive a corresponding locking pin spacing section 44 and a section configured and sized to receive a corresponding locking pin gripping section 46.
Each pin receiving aperture 74 is adapted to cooperate with a corresponding locking pin 42 in snappingly locking the rope clamping device 10 in its closed configuration.
A set of locking protuberances 76 extends integrally and outwardly from the closure member rope gripping lower surface 62. Each locking protuberance 76 has a generally block-shaped configuration defining a set of peripheral locking edges 78.
The intersection of the bass member groove recesses 40 with the groove bottom wall 36 defines a set of groove locking edges 80.
The locking protuberances 76 are positioned so that when the rope clamping device 10 is in its closed configuration, each locking protuberance 76 is in register with a corresponding base member groove recess 40.
In use, the rope clamping device 10 is adapted to clamp a rope such as the rope indicated by the reference numeral 82, in a loop configuration adjacent to a free end thereof.
In order to form a loop configuration such as the loop 84 of figure 7, a rope knot 86 is first tied in the rope 82 adjacent a first rope free end 88. A second rope free end 90 is then threaded into the first channel 26 from the base member 5 end wall 16 to the base member end wall 14. The rope 82 is then pulled through the first channel 26 until the knot 86 abuttingly contacts the abutment shoulder 28. The abutment shoulder 28 prevents the rope free end 88 from being pulled-out of the channel 26 through the aperture formed in the base 10 member end wall 14 by the channel 26.
The rope 82 is then bended in order to form the loop 84.
With the rope clamping device 10 in its opened configuration, a segment of the rope 82 which extends between the loop 84 and the second rope free end 90 is abuttingly rested inside the rope receiving channel 26. The closure member 13 is then pivoted about the hinge strips 68 in an overlying relationship relatively to the base member 12. The segment of the rope 82 which abuttingly rests atop the rope receiving channel 26 is thus sandwiched between the base member 12 and the closure member 13.
As illustrated in figure 7, the locking protuberances 76 are adapted to deform the rope 82 and to bias the rope 82 into the base member groove recesses 40. Consequently, the rope 82 will be engaged by the peripheral locking edges 78 of the locking protuberances 76 and the groove locking edges 80 of the base member groove recesses 40. The locking protuberances 76 and the base member groove recesses 40 are thus adapted to cooperate in preventing the longitudinal axial displacement of the segment of the rope 82 which is sandwiched between the base member 12 and the closure member 13.
It should be noted that although the rope clamping device 10 in accordance with the present invention is adapted to work with any suitable rope which fits into the first channel 26 and the base member groove 34, the rope clamping device 10 is A
particularly efficient with ropes having a substantially flattened configuration. For example, ropes having a substantially oval cross sectional configuration have proven to be particularly well suited for working with the rope clamping device 10.
The pivoting of the closure member 13 in an overlying relationship relatively to the base member 12 also allows for the insertion of the locking pins 42 into the pin receiving apertures 74. When the closure member 13 is squeezed against the base member 12, the locking pins 42 and the pin receiving apertures 74 cooperate in locking the rope clamping device 10 in its closed configuration.
In order to release the locking action of the rope clamping device l0, a pressure is exerted on the prehension tongue 70 so as to rotate the closure member 13 away from the base member 12. By exerting a pressure which biases the closure member 13 away from the base member 12, the rope clamping device 10 is moved back to its opened configuration and the rope 82 can be withdrawn from the rope receiving channel 26.
A typical type of application wherein a rope clamping device such as the rope clamping device 10 in accordance with the present invention can be used is illustrated in figure 1.
In this typical application, the rope clamping device 10 secures the rope 82 in a loop configuration 84. The rope 82 is adapted to secure the lower edge of a car shelter skirt 92 to a securing post 94. The rope 82 is thus threaded to an eyelet 96 provided in the lower peripheral edge of the skirt 92. The rope 82 is also wrapped around the post 94.
