Abstract

The pulley for a block and tackle system includes a shell, a sheave, and a pin. The shell includes a shell pinhole extending through the center of the shell. The sheave includes a sheave pinhole extending the center of the sheave. The pin extends through the shell pinhole and the sheave pinhole, the pin operable to fix a position of the sheave in two directions with respect to the shell. A swivel anchor point is connected to the shell; a hook is connected to the shell and opposite of the swivel anchor. A clasp is fixed to the opening of the hook, in which the hook is operable to connect the pulley to an object, and the clasp comprises wings extending outwardly from the latch.

[0010] The following detailed description of specific embodiments of the present disclosure can be best understood when read in conjunction with the following drawings, where like structure is indicated with like reference numerals and in which:

[0011] FIG. 1 shows an elevation view of the improved block, hook and clasp, in which the dual wings of the clasps are fixed to the opening of the hook. The hook is connect to the shell of the shell. A leadline or rope may be looped though the sheave.

[0012] FIG. 2 is a side view of the improved block, hook and clasp.

[0013] FIG. 3 is a side view of the improved block, hook and clasp, in which the block further includes a tethering hook.

[0014] FIG. 4 is a side view of the improved block and tackle in mock-up use.

[0015] The embodiments set forth in the drawings are illustrative in nature and not intended to be limiting to the claims. Moreover, individual features of the drawings will be more fully apparent and understood in view of the detailed description

DETAILED DESCRIPTION

[0016] Specific embodiments of the present disclosure will now be described. The different embodied forms should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting. As used in the specification and appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0018] Unless otherwise indicated, all numbers expressing distance, size, or other dimension that are modified by the term “about” as used in the specification and claims are to be understood to vary to the smallest significant figure. Additionally, the disclosure of any ranges in the specification and claims are to be understood as including the range itself and also anything subsumed within the range, as well as endpoints. Unless otherwise indicated, the numerical properties set forth in the specification and claims are approximations that may vary depending on the desired properties sought to be obtained in embodiments of the present disclosure. Notwithstanding that numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical values, however, inherently contain certain errors necessarily resulting from error found in their respective measurements.

[0019] As previously stated, some users may experience difficulty with operating the clasp of the pulley or block, when the pulley or block includes a clasp. Again, this is especially true for electrical lineman when they have their leather protector gloves and their rubber insulated gloves on. Accordingly, there is an ongoing need for blocks and tackles with increased dexterity with respect to the clasp.

[0020] Embodiments of the present application meet this need by attaching dual wings to the clasp of the hook of the pulley. Conventional clasps may not extend wider than the hook itself. Therefore, users have difficulty retracting the safety lock the pulley may be removed form the anchoring point. According to embodiments herein, the clasp may have a wing that extends outwardly from the clasp, and beyond the width of the hook. These wings may provide an additional contact point for the user to grasp and retract the safety lock such that the hook can be removed from the anchoring point. The wings of the present embodiments may increase the dexterity when the users own dexterity is inhibited, such as by PPE. Phrased differently, the wings of the present embodiment may be glove-friendly.

[0021] In one or more embodiments of this disclosure, the pulley includes a shell and a hook. The shell includes a shell pinhole, a sheave, and a pin. The shell pinhole extends through the center of the shell. The sheave includes a sheave pinhole, which extends through the center of the sheave. The pin extends through the shell pinhole and the sheave. The pin is configured to fix a position of the sheave in two directions with respect to the shell. The hook of the pulley is connected to the shell, and a clasp is fixed to the opening of the hook. In embodiments, the hook is configured to connect the pulley to an object. The clasp comprises two wings extending outwardly from the clasp.

[0022] In FIG. 1, the pulley 100 includes a shell 7 and a hook 1. The shell 7 includes at least two sheaves 5 and at least three faces 4. The hook 1 includes a clasp 2, and the clasp include two wings 3a and 3b. The clasp with the two wings may also be called the dual winged clasp. The dual winged clasp is configured to allow greater dexterity for a lineman in bulky rubber lined glove than a single winged clasp or a conventional clasp. In some embodiments, the pulley 100 may include a swivel anchor point 6 to prevent the rope from twisting, as shown in FIG. 1.

[0023] In FIGS. 2 and 3, the shell 7 includes a shell pinhole 9a, a sheave 5, and a pin 9. The shell pinhole 9a extends through the center of the shell. The sheave 5 includes a sheave pinhole, which extends through the center of the sheave. The pin 9 extends through the shell pinhole 9a and the sheave 5. The pin 9 is configured to fix a position of the sheave in two directions with respect to the shell. As shown with particularity in FIG. 3, the shell 7 further includes a shell hook 8.

[0024] In FIG. 4, the hook 1 of the pulley 100 is connected to the shell 7, and a clasp 2 is fixed to the opening of the hook 1. In embodiments, the hook 1 is configured to connect the pulley to an object 30. Rope 20 is threaded through the pulley 100, and the excess rope 20 is wrapped under the shell hook 7.

[0025] While embodiments have been described herein with reference to a fixed pulley or block, applicability to various other types of pulleys and blocks is envisioned, such as, but not limited to snatch blocks, tear drop pulleys, tailboard blocks, blocks with hooks, or blocks with shackles. Additionally, clasps with wings, as described herein, may be applicable to additional applications, not just limited to pulleys, blocks, or blocks and tackles.
