Strap Tighteners Patents (Class 24/69ST)
  • Patent number: 6049950
    Abstract: An adjustable BUNGEE cord device for fastening, securing or mounting objects together or to a stationary object. The device comprises at least two sections of conventional BUNGEE cord, each having a means for attaching the cord sections to each other or to some stationary object, such as metal hooks. One of the cord sections is firmly attached to a locking mechanism via a roll pin positioned near the middle of the locking mechanism. This cord section extends from the locking mechanism through a slot which runs from the roll pin to the edge of the locking mechanism. The other cord section is slidably engaged with the locking mechanism via a slot which extends completely from one end of the locking mechanism to the other. The locking mechanism further comprises a latch hook comprising a lip for securing it in the closed position, a pin hole for rotatably attaching it to the locking mechanism, and a serrated edge for gripping the cord section when the latch hook is in its closed position.

  • Patent number: 5592722
    Abstract: Closure device particularly for sports shoes including a shell and a quarter and provided with a first flap and a second flap to be secured or with straps to be tensioned and secured. The device includes grip elements and at least one engagement element which are associable respectively with the first flap and with the second flap, or with the shoe and with the band. The grip elements selectively and detachably interact with the engagement element by using an auxiliary lever. The device has low manufacturing costs, allowing to standardize the individual components and limiting protrusions with respect to the surfaces of the shoe.

  • Patent number: 5494387
    Abstract: A tensioning apparatus for a cargo lashing strap that secures cargo to a cargo deck and is configured to have a frame having a first portion adapted to couple the frame to the cargo deck an intermediate portion, and a second portion. The frame has two side walls extending continuously therealong and are generally parallel to one another in the first and second portions, and taper in the intermediate portion. A spindle receives the cargo lashing strap and extends through apertures in the side walls in the second portion of the frame. The spindle is provided with an axial slot therethrough for engaging the cargo lashing strap. Ratchet wheels arranged on the first and second spindle ends, rotate with the spindle. An adapter facilitates engagement and disengagement of a torquing lever with the spindle. A pawl shaft has ends that extend through apertures in both side walls in the second portion of the frame.

  • Patent number: 4843688
    Abstract: A compact buckle, streamlined in appearance, comprises a main body and a stopper piece. The main body includes a pair of side frames, and three shafts disposed between the side frames in such a manner as to extend from one side frame to the other. The stopper piece is axially and pivotably supported between the side frames. The stopper piece is provided with a retaining projection which has a sloped surface for cooperating with a correspondingly sloped surface of a winding shaft, which is one of the aforenoted three shafts, in order to frictionally engage and entrap a belt portion therebetween thereby securing the belt portion within the buckle.

  • Patent number: 4751770
    Abstract: The present invention is drawn to a clasping device for fixing a cargo item such as an automobile on a load carrying platform. The main assembly (A) of the clasping device has a body (B) and lever (C). Body (B) includes a main body (B.sub.1) and a sub-body (B.sub.2). The main body (B.sub.1), the sub-body (B.sub.2) and the lever (C) are pivotally connected to each other by pins (8a, 8b). In the release condition, the main body (B.sub.1) and the sub-body (B.sub.2) are bent and form a V-shape in association with each other due to the tension exerted and remaining on the strap (21).

  • Patent number: 4584741
    Abstract: A clasping device which has a main assembly including a body, and a lever connected by means of links. A first hook is connected with the body, while a second hook is connected with the lever by means of a strap. The strap can be tightened and loosened by rotating the lever between the release and tightening positions. The body has a claw member for temporarily holding the tightened strap. Therefore, by utilizing the claw member, the lever can be repeatedly operated in order to increasingly tighten the strap.

  • Patent number: 4527309
    Abstract: A clasping device for fastening a large cargo which includes a lever pivotally connected to a body through a pair of links. A belt is tightened by pivoting the lever relative to the body in a fastening direction in such a way that the pivotal connection between the links and the lever move in the direction of the interior of the body when the lever is pivoted in a fastening direction, thereby to render the device compact in the fastening position.

  • Patent number: 4451956
    Abstract: A clasping device which has a body and a manipulatable lever pivotally connected to the body. The body has at least two connecting members extending between a pair of side plate members thereof, one of the connecting members can contact a strap connected to the lever means during the usual use to firmly hold the lever in a locked position. The other of the connecting members can contact the strap when the assembly of the body and the lever is turned upside down, to hold the lever in the locked position. A large part of the lever is housed in the pair of side plate members of the body substantially in parallel to the body in the locked position, whereby the construction of the assembly is easy to handle and so firm as to be resistant to any big loads.

  • Patent number: 4395796
    Abstract: A strap tightener in which a specific releasable tensioning and clasping mechanism for a strap is incorporated to hold heavy loads under tension firmly in a given position. The strap tightener can advantageously be used to tie down cargo containers, motor vehicles and the like heavy loads to fixing structures on carrier vessels or carts. The strap tightener has a simple and economical structure with a reduced number of parts and is thus smoothly operable to attain good strap tensioning without incurring any damage of the strap and any loosening of the tensioned strap during the use.

  • Patent number: 4396038
    Abstract: Set out herein are improvements to pipe thread protectors of the type described in U.S. Pat. No. 3,038,502 to Hauk et al., characterized by a band buried within a split torroidal envelope with the band ends being pulled together by a cam operated lever. It is the improved structure of the cam and the attached lever configuration resulting in manufacturing convenience that is set out herein. The cam is generally conformed as a cut out on the interior of a cylindrical sleeve which is provided with a release recess through which the lever may be inserted or withdrawn. These features permit the complete forming of the lever and the cam while separated thus allowing techniques like investment casting to be used for the construction thereof.
