La roulette selon l'invention se caractérise essentiellement par le fait qu'elle comporte une roue 1 apte à rouler autour d'un premier axe 2, une chape 3 comportant au moins un bras 4 comportant au moins un palier 5 définissant un deuxième axe 6, un arbre 7 pour monter la roue 1 en rotation par rapport au palier 5, un flasque 8 interposé entre une face latérale 9 de la roue 1 et le bras 4, ce flasque présentant la forme d'une poche sphérique 34 centrée sur un troisième axe 35, des moyens 10 pour accrocher le flasque à la roue de façon que les axes 2 et 35 soient confondus et des moyens 30 pour lier au moins un point du bras 4 au flasque 8 de façon que les axes 6 et 35 soient confondus. Application, notamment, aux roulettes aptes à être associées aux pieds de meubles ou appareils divers en vue de favoriser leur déplacement sur une surface donnée.

A caster wheel assembly 1' for a shopping trolley comprises a support member 2' fixed to a trolley chassis, a carrier member 4' freely rotatable about a vertical axis 5' with respect to the support member 2', and a wheel 6' carried by the carrier member 4' so as to be rotatable about a horizontal axis 7' offset from the vertical axis 5'. A cam follower 24' in the form of two planet wheels 26' rotatably mounted on a lower portion 30 of the support member 2' engages a cam surface 21' having an undulating profile on the carrier member 4' in order to bias the wheel 6' of the assembly towards a direct forward line. In order to steer the trolley to one side or the other of the direct forward line, a sufficient steering force must be applied to the trolley in order to overcome this biasing action, and this overcomes any tendency of the trolley to move in a direction other than the intended direction of travel.

The invention relates to an attachment arrangement (1, 32, 40) for attaching a caster (2) to an object. The attachment arrangement comprises: a caster housing (5), a washer means (11, 33, 41) provided with a upper contact surface (24), a fastening means (10, 37, 45) provided to fasten the washer means (11, 33, 41) and the caster housing (5) to an object. The washer means (11, 33, 41) is provided with a side contact surface (25) and an transitional contact surface (26), which transitional contact surface (26) is provided between the upper and side contact surfaces (24, 25) of the washer means (11, 33, 41) which upper, side and transitional contact surfaces (24, 25, 26) of the washer means (11, 33, 41) are provided with substantially corresponding inverse shape to upper, side and transitional contact surfaces (21, 22, 23) of the caster housing (5). At least the upper and transitional contact surfaces (24, 26) of the washer means (11, 33, 41) are provided to abut against corresponding upper and transitional contact surfaces (21, 23) of the caster housing (5).

A caster comprises a body including a stem cavity with a stem of the caster rotatably mounted in the stem cavity to permit rotation of the stem relative to the body about a stem access. The stem may comprise a spline shaft extending from the stem into the stem cavity. The stem and spline shaft are operatively connected. The stem cavity may have a spline bushing. The spline bushing and the body are operatively connected to each other. The spline shaft and the spline bushing are releaseably interlockable. One of the spline bushing and the spline shaft may be movable in a direction along the stem axis between the swivel position wherein the spline shaft is not engaged with the spline bushing, and a fixed position wherein the spline shaft is engaged with the spline bushing.

Die Erfindung betrifft ein Flurförderzeug (1), insbesondere Hubwagen, mit einem Antriebsrad und zumindest einer von dem Antriebsrad seitlich beabstandeten Stützrolle (6a; 6b), wobei die Stützrolle (6a; 6b) um eine horizontale Drehachse (D) drehbar in einer Schwinge (10) gelagert ist, die um eine Schwenkachse (S) schwenkbar in einem Drehschemel (11) gelagert ist, und die Stützrolle (6a; 6b) mittels eines elastischen Kunststoffelements (20), insbesondere eines Elastomerelements, an dem Drehschemel (11) federnd abgestützt ist und das Kunststoffelement (20) zwischen der Schwinge (10) und dem Drehschemel (11) angeordnet ist. Erfindungsgemäß ist zwischen der Schwinge (10) und dem Drehschemel (11) eine metallische Feder (22), insbesondere eine Stahlfeder, angeordnet.
摘要:
A truckle assembly has a housing (1), a rotating unit (2) movably mounted on the housing, a limiting unit (3) and a wheel assembly (4). The housing includes a body (10) and a sleeve (11). A slope portion (13) is formed inside the body and neighboring the sleeve. The rotating unit includes a central shaft (21), and a gear ring (22) mounted on the central shaft for corresponding to a first side of the slope portion. The limiting unit includes a pedal (31), an interferential portion (32) linking an end of the pedal, and an arresting portion (33) linking an end of the interferential portion. The pedal has a first portion extending into the housing, and a second portion extending out of the housing. The interferential portion corresponds to a second side of the slope portion. The wheel assembly includes at least a wheel (4) assembled on sides of the housing, and a shaft pole (42) extending through the wheels and the pedal.
