  • Patent number: 4768782
    Abstract: A bicycle exercising apparatus which allows the user to place the rear wheel of a bicycle therein for stationary pedaling exercise. The apparatus supports the rear wheel of the bicycle and does not require the removal of the front wheel. The frame of the apparatus forms a support to the rear axle of the rear wheel, and an adjustable load mechanism, including a fly wheel and a wind cage, provides a resistance against the pedaling force of the user. The elements of the frame may be pivotally connected such that the frame is collapsable for ease of transportation and storage.

  • Patent number: 4640449
    Abstract: A bicycle bottle cage having an attachment mechanism that will securely fasten the cage to the handle bars of a bicycle. The bottle cage portion has a generally conventional configuration. An attachment bracket is welded to the rear portion of the cage and includes a continuous loop formed to serpentine fashion to extend over the handle bars and beside and over the goose neck. A clamp plate extends beneath the goose neck to engage each side of the attachment bracket. The clamp plate includes a lock screw which engages the bottom of the goose neck to firmly attach the bracket thereto.

  • Patent number: 4487344
    Abstract: A pannier carrier (23, 23') for bicycles including a frame arrangeable substantially centered with respect to an associated bicycle wheel for supporting carrying bags (70). The frame is formed by a pair of mirror-image open frameworks (26, 26') disposed on respective sides of a turning fork (12) of an associated bicycle (10) for proper distribution of weight. Attachment of these frameworks (26, 26') to the turning fork (12) is accomplished for each of the frameworks (26, 26') by a connecting bracket (42) securable to an apertured lug (22) conventionally provided on each branch (16, 16') of a turning fork (12) of a bicycle (10) adjacent the point of attachment of the axle of the associated wheel (20), and by a standoff (60, 60') which space the frameworks from the associated branches (16, 16') to offset the slant of the turning fork branches. The frameworks (26, 26') can be spread apart and rigidified by a spreader bar ( 76) which can have an article support frame (92) provided at its top portion.

  • Patent number: 4185511
    Abstract: A torque-transmitting, torque-sensing system has a first rotatable shaft which can be shifted radially in two orthogonally-displaced directions to be precisely concentric with a second rotatable shaft, has a first coupling element which is rotatable with but which is movable axially relative to one of those rotatable shafts, has a biasing means which urges the first coupling element for movement axially in one direction relative to the one rotatable shaft, has a second coupling element which is rotatable with the other rotatable shaft, and has a surface on one of those coupling elements which coacts with a complementary surface on the other of those coupling elements to enable those coupling elements to transmit torque from that rotatable shaft which is the driving shaft to that rotatable shaft which is the driven shaft while permitting the first coupling element to respond to a predetermined increase in rotation resistance of the driven shaft to move axially in the opposite direction relative to the one rota

  • Patent number: 4154382
    Abstract: A bicycle rack including an elongated load support frame, a U-shaped main strut attached to a mid-length portion of the support frame so that its two legs extend downwardly therefrom, a substantially V-shaped lateral bracing strut attached to an end portion of the support frame so that its two legs extend downwardly to attach to respective legs of the main strut, and a U-shaped stiffening strut attached proximate the other end portion of the support frame so that its two legs extend downwardly to attach to respective legs of the main strut, and an elongated bracket to connect the frame of the rack to the bicycle.

  • Patent number: 4082142
    Abstract: A housing, for the expansion unit of a cooling system, has a top wall, a bottom wall and end walls; and those walls define a space which accommodates that expansion unit. That housing has a front opening which is filled by an air-distributing transition member; and it has a rear opening that is substantially closed by an air-guiding member. That air-guiding member can support a motor and a pair of multi-vane blowers, or it can be an angular transition for a single blower. That air-guiding member is shorter than the rear opening to provide a short space which can accommodate the supply and return headers of the expansion unit. That air-guiding member can be set in either of two predetermined positions relative to that rear opening to permit the supply and return headers to be located at either end of the housing.
