Abstract

A pullhead includes a housing that has a first end and a second end. The housing is separable between a first body and a second body. The first and second bodies are pivotally coupled at a joint and the first and second bodies together define an interior pocket of the housing. The interior pocket has an interior pocket width. The pullhead head includes a pulling feature at the first end. The interior pocket includes an interior retainer flange that has an inner width and is disposed within the interior pocket. The inner width is less than the interior pocket width. The first body and second body are pivotable relative to each other around an axis at the joint that is transverse to a pulling direction.

Dependent claims

A pullhead comprising:

a first body including a first end and a second end, the first end including a first end attachment feature and the second end including a second end attachment feature;
a second body including a first end and a second end, the first end of the second body including a first end attachment feature and the second end of the second body including a second end attachment feature;
wherein the first body and the second body are configured to be connected to each other to cooperatively define a main shell, the main shell including an inner cavity with a first end and a second end;
wherein the first end attachment feature of the first body and the first end attachment feature of the second body are configured to interlock to limit radial movement of the first end of the first body relative to the first end of the second body;
and
a retainer with an aperture configured to receive the second end attachment feature of the first body and the second end attachment feature of the second body to limit radial movement of the second end of the first body relative to the second end of the second body, wherein the second end attachment feature of the first body and the second end attachment feature of the second body are at least partially surrounded by the retainer when received into the retainer aperture.

A pullhead comprising:

a first body including a first end and a second end, the first end including a first end attachment feature and the second end including a second end attachment feature;
a second body including a first end and a second end, the first end of the second body including a first end attachment feature and the second end of the second body including a second end attachment feature;
wherein the first body and the second body are configured to be connected to each other to cooperatively define a main shell, the main shell including an inner cavity with a first end and a second end;
wherein the first end attachment feature of the first body and the first end attachment feature of the second body are configured to interlock to limit radial movement of the first end of the first body relative to the first end of the second body;
and
a retainer configured to engage the second end attachment feature of the first body and the second end attachment feature of the second body to limit radial movement of the second end of the first body relative to the second end of the second body, wherein at least a portion of the retainer is positioned around the second end attachment feature of the first body and the second end attachment feature of the second body;
wherein the first body and the second body are configured to connect and disconnect from each other without fasteners;
wherein the second end attachment feature of the first body includes an extension and the second end attachment feature of the second body includes an extension, wherein when the first and second bodies are connected, the extensions of the second end attachment features are positioned adjacent each other and at least a portion of the retainer is positioned around both of the extensions of the second end attachment features;
wherein the extension of the second end attachment feature of the first body is an eye pulling extension with an eye pulling aperture, and wherein the extension of the second end attachment feature of the second body is an eye pulling extension with an eye pulling aperture, wherein the eye pulling aperture of the first body is aligned with the eye pulling aperture of the second body;
further comprising a first rib that connects the extension of the first end attachment feature of the first body to an interior side of the first body and a second rib that connects the extension of the second end attachment feature of the second body to an interior side of the second body;
and
wherein the retainer is a collar with a through aperture that matches a periphery profile of the eye pulling extensions of the first and second bodies when they are positioned adjacent each other such that the retainer can be slid over the eye pulling extensions to prevent the eye pulling extensions of the first and second bodies from moving away from each other.
