  • Patent number: 6565058
    Abstract: Promotional devices configured to removably support articles (e.g., papers, photographs, etc.) for viewing are provided. A device includes a housing and a pair of arms pivotally disposed within the housing in adjacent spaced-apart relationship. The housing includes a base portion that is configured to be supported on a surface and an upper portion that is movably secured to the base portion. The housing upper portion is movable between a distal position and a proximal position relative to the housing base portion. Movement of the housing upper portion from the distal position to the proximal position causes the upper end portions of the arms to separate so that an article can be placed therebetween. The arms are urged together so as to retain the article placed therebetween and the housing upper portion is moved to the distal position.

  • Patent number: 6530130
    Abstract: Clip arrangement for fixing a strip, in particular a decorative strip in a vehicle, with a retaining part (1) and a snap-on part (2), wherein the retaining part has a receiving slot (13) with an upper guide (14) and a lower guide (17), into which receiving slot (13) there projects obliquely at least one latching finger (15) having a latching opening (16) at its free end, wherein the snap-on part (2) also has at least one projection (23) with a plurality of latching lugs (24) which can latch with a latching opening (16) when the projection (23) is inserted into the receiving slot (13). Each latching finger (15) is designed and directed in such a way that it can gently yield to the latching lugs (24) when the projection (23) is inserted into the receiving slot (13), but prevents the snap-on part (2) from being withdrawn after the latching lugs (24) have been latched into latching openings (16).

  • Patent number: 5944236
    Abstract: An apparatus for clipping two or more articles of clothing, such as socks, together. The apparatus includes two jaw members which are hingeably attached and a securing member that has two arms which are respectively positioned in two channels in the two jaw members. The securing member is slidable between a closed position, where it urges the two jaw members inward to thereby securely clamp the two articles of clothing therebetween, and an open position where one of the arms is not engaged with one of the jaw members allowing the jaw members to be separable to permit removal of the two articles of clothing. The apparatus includes a latch mechanism comprised of a ridge in one of the channels and a lip in the corresponding arm which engage to retain the securing member in the closed position. The apparatus is used to keep articles of clothing together during washing and drying.

  • Patent number: 5791024
    Abstract: A side-actuated clip that is actuated by using only one hand. The clip consists of two halves, withone stationary and the other pivotal. A pivot shaft having a helical shape passes through a mounting bracket of the second, pivotal plate-half. The mounting bracket has an interior opening corresponding to the shape of the helically-shaped pivot shaft. The pivot shaft is spring biased. As the pivot shaft is translated in the mounting bracket secured to the second, pivotal plate-half, such movement causes the second plate-half to pivot open or closed, depending upon the direction of translation of the pivot shaft. The spring biases the shaft in a linear direction that pivots the second plate-half into its closed, clamping position.

  • Patent number: 5457857
    Abstract: A clamp, for example of the conventional "clothes peg" type, is provided with a wedging device 9 which may be selectively locatable between the rear ends of the two clamping members 2 so as to urge the rear ends apart, and thereby by virtue of the pivotal connection 4 between the clamping members 2 to urge the clamping jaws 3 together. In this way the wedging device 9 acts to increase the strength of the clamp in order to reduce the possibility of the items held between the jaws of the clamp from slipping out of the clamp. A locking member is also provided to prevent the wedging member from being unintentionally released.

  • Patent number: 5400478
    Abstract: A clip and method of using same to facilitate the positioning of a cover of the typical rectangular bag-like type over a typical rectangular bedding item such as a blanket, quilt, comforter or the like. The clip is formed with two opposed selectively engageable jaws dimensioned to permit engagement of the corners of the bedding item and cover therebetween. The clip is formed with a padded cover overlying the outside surfaces of the clip. In use, the cover typically formed with a closed end and an open end is turned inside out and positioned so that the closed corners of the inside out bag lie adjacent the corners of the bedding item. These adjacent corners of the cover and bedding item are then clipped together using one clip at each corner. The cover is then drawn over the bedding item to turn the cover right side out and simultaneously enclose the bedding item. The free corners of the cover and bedding item may if desired be clipped together, preferably within the cover.
