Abstract

A tool for aligning a first rail segment with a second rail segment includes an elongated rigid member, a first arrangement, and a second arrangement. The member is configured to be positioned in an overlapping state with the first rail segment and the second rail segment. The first arrangement engages a first end portion of the first rail segment and is actuated to urge the first end portion towards the elongated rigid member. The second arrangement engages a second end portion of the second rail segment and is actuated to urge the second end portion towards the elongated rigid member. When each of the first end portion and the second end portion is urged towards the elongated rigid member, the first rail segment and the second rail segment adjoin and fall in alignment with each other to be connected together and form a contiguous rail portion of a rail line.

First claim

What is claimed is:

1 . A tool for aligning a first rail segment with a second rail segment, the tool comprising:
an elongated rigid member configured to be positioned in an overlapping state with respect to each of the first rail segment and the second rail segment; a first arrangement configured to engage a first end portion of the first rail segment and be actuated to urge the first end portion towards the elongated rigid member; and a second arrangement configured to engage a second end portion of the second rail segment and be actuated to urge the second end portion towards the elongated rigid member,
wherein when each of the first end portion and the second end portion is urged towards the elongated rigid member, the first rail segment and the second rail segment adjoin and fall in alignment with each other to be connected together and form a contiguous rail portion of a rail line.

2 . The tool of claim 1 , wherein each of the first arrangement and the second arrangement includes one or more clasping mechanisms, each clasping mechanism of the one or more clasping mechanisms including:
a foot peg to clasp the first end portion or the second end portion respectively of the first rail segment or the second rail segment, enabling the first arrangement or the second arrangement to correspondingly engage with the first end portion or the second end portion.

3 . The tool of claim 2 , wherein each clasping mechanism further includes a shifting system to move the foot peg to actuate the first arrangement or the second arrangement, the shifting system including:
a spacer fixedly coupled to the elongated rigid member and defining a through-bore; and a fastener passing through and being freely rotatable with respect to the through-bore, the fastener being threadably coupled to the foot peg,
wherein when the fastener is rotated with respect to the foot peg, a head of the fastener abuts against the spacer and the foot peg moves towards the elongated rigid member to urge the first end portion or the second end portion towards the elongated rigid member.

4 . The tool of claim 3 , wherein the foot peg is angularly rotatable about a longitudinal axis of the fastener, the foot peg defines a first surface and a second surface and each clasping mechanism includes a stopper to selectively abut with the first surface and the second surface to restrict a rotation of the foot peg about the longitudinal axis within an angular threshold range.

5 . The tool of claim 4 , wherein
when the foot peg is at one angular limit of the angular threshold range, the stopper is abutted with the first surface and the foot peg is at a first condition to engage the first end portion or the second end portion; and when the foot peg is at another angular limit of the angular threshold range, the stopper is abutted with the second surface and the foot peg is at a second condition to clear a path for the first end portion or the second end portion to be either brought into or be removed from the overlapping state with respect to the elongated rigid member.

6 . The tool of claim 4 , wherein the foot peg defines a curved transition region extending between the first surface and the second surface such that the first surface, the second surface, and the curved transition region, forms a continuous uninterrupted surface.

7 . The tool of claim 4 , wherein the stopper is immovably coupled with respect to the elongated rigid member and includes a flat face to abut with the first surface and the second surface.

8 . The tool of claim 2 , wherein
the elongated rigid member defines a first part and a second part away from the first part; and the one or more clasping mechanisms of the first arrangement corresponds to a plurality of clasping mechanisms arranged on opposing lateral sides of the first part of the elongated rigid member.

9 . The tool of claim 2 , wherein
the elongated rigid member defines a first part and a second part away from the first part; and the one or more clasping mechanisms of the second arrangement corresponds to a plurality of clasping mechanisms arranged on opposing lateral sides of the second part of the elongated rigid member.

10 . The tool of claim 6 , wherein
in the overlapping state, the elongated rigid member is aligned with each of the first rail segment and the second rail segment such that a first part of the elongated rigid member is disposed along a first extension of the first rail segment and a second part of the elongated rigid member is disposed along a second extension of the second rail segment.

11 . A method for aligning a first rail segment with a second rail segment, the method comprising:
positioning an elongated rigid member in an overlapping state with respect to each of the first rail segment and the second rail segment; engaging a first end portion of the first rail segment by using a first arrangement and actuating the first arrangement to urge the first end portion towards the elongated rigid member; and engaging a second end portion of the second rail segment by using a second arrangement and actuating the second arrangement to urge the second end portion towards the elongated rigid member;
wherein when each of the first end portion and the second end portion is urged towards the elongated rigid member, the first rail segment and the second rail segment adjoin and fall in alignment with each other to be connected together and form a contiguous rail portion of a rail line.

12 . The method of claim 11 , wherein each of the first arrangement and the second arrangement includes one or more clasping mechanisms, each clasping mechanism of the one or more clasping mechanisms including:
a foot peg to clasp the first end portion or the second end portion respectively of the first rail segment or the second rail segment, enabling the first arrangement or the second arrangement to correspondingly engage with the first end portion or the second end portion.

13 . The method of claim 12 , wherein each clasping mechanism further includes a shifting system to move the foot peg to actuate the first arrangement or the second arrangement, the shifting system including:
a spacer fixedly coupled to the elongated rigid member and defining a through-bore; and a fastener passing through and being freely rotatable with respect to the through-bore, the fastener being threadably coupled to the foot peg, the method further including:
rotating the fastener with respect to the foot peg such that a head of the fastener abuts against the spacer and the foot peg moves towards the elongated rigid member to urge the first end portion or the second end portion towards the elongated rigid member.

14 . The method of claim 13 , wherein the foot peg is angularly rotatable about a longitudinal axis of the fastener, the foot peg defines a first surface and a second surface and each clasping mechanism includes a stopper to selectively abut with the first surface and the second surface to restrict a rotation of the foot peg about the longitudinal axis within an angular threshold range.

15 . The method of claim 14 , wherein
when the foot peg is at one angular limit of the angular threshold range, the stopper is abutted with the first surface and the foot peg is at a first condition to engage the first end portion or the second end portion; and when the foot peg is at another angular limit of the angular threshold range, the stopper is abutted with the second surface and the foot peg is at a second condition to clear a path for the first end portion or the second end portion to be either brought into
