The present disclosure relates to a clamping assembly, and more particularly to a clamping assembly for permitting passage of an elongated member through a wall.
Elongated members, such as hoses, are often required to be passed through walls, such as a wall of a machine surface. Conventionally, connectors such as, cut-outs with p-clips or stauff clamps and the like are employed. Typically, in order to pass the elongated members through the walls, the elongated members are required to be broken into two parts. A connector is then attached to a hole on the wall and the parts of the elongated members are connected on both sides of the connector.
U.S. Pat. No. 6,957,817 discloses a seal assembly comprising an elastomeric gland having insert openings and fastener openings. Elastomeric inserts are removably disposed in the gland insert openings. The inserts have removable portions to form one or more cable openings. Thus, cable(s) can be placed in the cable openings. End plates are disposed at each end of the gland. The end plates are formed of complementary plate members, which, when mated together, form a unitized end plate defining fastener openings and cable openings.
In one aspect, the present disclosure provides a clamping assembly for permitting passage of an elongated member through a wall. The clamping assembly includes a first clamping member and a second clamping member. The first clamping member includes a first arm extending outwardly from a first central portion of the first clamping member. The second clamping member includes a second arm extending outwardly from a second central portion of the second clamping member. The second clamping member is configured to be removably engaged with the first clamping member, such that the first arm and the second arm define an opening for permitting passage of the elongated member through the wall.
In another aspect, the present disclosure also discloses a method of permitting passage of an elongated member through a wall. The method includes receiving the elongated member through an aperture on the wall; engaging a first clamping member to the aperture; engaging a second clamping member to the first clamping member; inserting a tightening member through each of a first hole of the first clamping member and a second hole of the second clamping member; and, turning the tightening member for locking the second clamping member with respect to the first clamping member.

At step 504, the second clamping member 104, is engaged to the first clamping member 102. Specifically, the second clamping member 104 is positioned proximate to the first clamping member 102 and rotated such that the projecting portion 142 of the second clamping member 104 engage with the cut-out portion 138 of the first clamping member 102. The engaging of the second clamping member 104 with the first clamping member 102 positions the first arm 110 adjacent to the second arm 116, whereby the openings 106 is defined around the elongated members 20 by the first arm 110 and the second arm 116. Due to such engagement of the first clamping member 102 and the second clamping member 104, the aperture 30 is sealed. Therefore, any likelihood of pressure drop, leakage, seepage and other such problems through the aperture 30 is avoided.
At step 506, the tightening member 120 is inserted through each of the first hole 136 and the second hole 144. Upon insertion, the free end portion 122 of the tightening member 120 may engage with the nut 124.
At step 508, the tightening member 120 is turned for locking the second clamping member 104 with respect to the first clamping member 102. The tightening member 120 may alternatively be turned in an opposite direction for unlocking the second clamping member 104 with respect to the first clamping member 102. The tightening member 120 may be conveniently turned by application of torque, for example using any conventional turning device, such as a wrench.
In an embodiment of the present disclosure, both the first clamping member 102 and the second clamping member 104 may engage to the aperture 30 from one side of the wall 10. Further, the tightening member 120 may be inserted from the same side of the wall 10. Therefore, the method 500 of permitting passage of the elongated members 20 through the wall 10 may be carried out from one side of the wall 10. Accordingly, the need of having access to both the sides of the wall 10 is avoided.
