Definitions
- This invention relates to a caster or roller for mounting to an article of furniture to provide movement of the article of furniture on a support surface such as a floor, and more particularly to a caster or roller assembly having a locking feature for selectively preventing movement of the article of furniture on the support surface.
- a caster or roller is commonly mounted to an article of furniture to enable the article of furniture to be moved on a support surface such as a floor.
- the caster or roller includes a wheel or roller member, which engages the support surface and rotates so as to enable movement of the article of furniture on the support surface.
- Certain types of casters or rollers include a locking feature for selectively preventing rotation of the wheel or roller member, to selectively prevent movement of the article of furniture on the support surface.
- Some locking rollers have a lever that is movable between a locking position and a release position. The lever selectively actuates and releases a locking mechanism that is configured to prevent rotation of the wheel or roller member when actuated.
- Other types of locking mechanisms have a self-locking feature, which prevents rotation of the wheel or roller member when a load is placed on the article of furniture.
- Self-locking rollers of this type are used when it is desired to automatically prevent movement of the article of furniture at certain times, such as to maintain a chair in position when an occupant is in the seat of the chair, and to allow ease of movement of the article of furniture at all other times, e.g. when the chair is unoccupied. It is an object of the present invention to provide a self-locking roller assembly for use with an article of furniture such as a chair. Another object of the invention is to provide such a self-locking roller assembly which is well suited for use with an article of furniture having a base that includes a laterally extending base member to which the roller assembly is mounted.
- a self-locking roller assembly which includes a uniquely configured housing having an engagement surface for selectively preventing rotation of the wheel or roller member of the roller assembly.
- a still further object of the invention is to provide such a self-locking roller assembly which is relatively sfmTple ⁇ fPits doMponerrfs and construction, so as to provide ease of assembly and manufacture, yet which is configured to effectively prevent rotation of the wheel or roller member when a load is placed on the article of furniture.
- a locking roller assembly for use with an article of furniture includes a housing defining an interior within which a wheel or roller member is located.
- the housing includes an opening through which a lower portion of the wheel extends, for engagement with a support surface such as a floor.
- the wheel or roller member is mounted to an axle.
- a movable mounting arrangement is interposed between the housing and the axle, for providing movement of the housing relative to the axle between a raised position and a lowered position.
- a biasing arrangement is interposed between the housing and the axle, for biasing the housing toward the raised position.
- the housing includes an engagement surface in vertical alignment with the wheel. When the article of furniture is not loaded, the biasing arrangement maintains housing in the raised position in which the engagement surface is positioned out of engagement with the wheel, so that the wheel is freely rotatable to provide movement of the article of furniture on the support surface.
- the housing When a load or other downward force is applied to the article of furniture, the housing is moved downwardly relative to the wheel toward the lowered position, against the force of the biasing arrangement. Such downward movement of the housing causes the engagement surface to move into contact with the wheel, to prevent rotation of the wheel and to thereby prevent movement of the article of furniture when the article of furniture is loaded.
- the biasing force of the biasing arrangement functions to move the housing toward the raised position, which moves the engagement surface out of engagement with the wheel. In this manner, the article of furniture can then be freely moved on the support surface as long as the load on the article of furniture is relieved.
- the axle is engaged with the housing via a guide arrangement that guides vertical movement of the axle as the housing is moved between the lowered position and the raised position.
- the axle guide arrangement is preferably in the form of a pair of slots formed in spaced apart walls that at least in part define the housing interior, and which are cd ⁇ f ⁇ guted to receive ' eritf ⁇ ortlort ⁇ of the axle.
- the slots are vertically oriented, so that the slots guide vertical movement of the axle as the housing is moved between the lowered and raised positions.
- the housing includes a laterally extending passage, which is configured to receive a component of the article of furniture for use in mounting the roller assembly to the article of furniture.
- the housing includes an end wall that is in line with the laterally extending passage, and which is configured to at least in part define the interior of the housing.
- the engagement surface is defined by an inner surface of the end wall.
- Fig. 1 is an isometric view of a representative article of furniture incorporating the locking roller assembly of the present invention
- Fig. 2 is a section view taken along line 2-2 of Fig. 1
- Fig. 3 is a section view taken along line 3-3 of Fig. 2, showing a housing of the locking roller assembly in a raised position for enabling movement of the article of furniture
- Fig. 4 is a view similar to Fig.
- an article of furniture in the form of a combination chair and desk assembly 10 generally includes a chair section 12 and a desk section 14.
- Chair section 12 includes a chair 16 having a seat 18 and a back 20, and is supported by a chair support pedestal 22.
- Desk section 14 includes a desk top 24 supported by a vertical desk top s ⁇ lppiort'2 ' 6.”"' l A" l b'a l ke' l!
- Base assembly 28 is configured to secure chair section 12 and desk section 14 together in a fixed relationship.
- base assembly 28 includes a transverse front support member 30, a generally U-shaped rear support member 32, and an axial center support member 34 that extends between and interconnects front support member 30 and rear support member 32. The lower ends of chair support pedestal 22 and desk support 26 are secured to center support member 34, for fixing chair section 12 and desk section 14 to base assembly 28.
- each locking roller assembly 40 is mounted to each end of front support member 30 and rear support member 32.
- each locking roller assembly 40 facilitates movement of chair and desk assembly 10 when chair section 12 is unoccupied, and selectively prevents movement of chair and desk assembly 10 when a user is seated in chair section 12.
- each locking roller assembly 40 includes a housing 42, which includes a generally tubular mounting section 44 configured to receive and engage the end portion of front support member 30 or rear support member 32.
- Tubular mounting section 44 includes an annular wall that defines a laterally open passage 46, which forms a portion of the interior of housing 42.
- Passage 46 is configured so as to enable an end portion of either front support member 30 or rear support member 32 to be received and engaged within passage 46.
- a threaded opening 48 is formed in the lower area of each support member end portion. Threaded opening 48 is configured to receive the threads of a fastener, such as a screw 50, which extends through an opening 52 in the lower area of tubular mounting section 44. Engagement of the threads of screw 50 within threaded opening 48 functions to selectively mount locking roller assembly 40 to the end portion of the support member.
- Housing 42 further includes an end wall 54, which is formed so as to define a vertical lower section 56 and a sloped section 58 that extends between vertical lower section 56 and the wall of housing 42 that defines tubular mounting section 44.
- the end portion of housing 42 includes a downwardly facing opening 64.
- a wheel or roller member 66 is disposed within the end portion of the interior of housing 42, and defines a lower portion that extends through opening 64 so that wheel or roller member 66 engages a support surface S, such as a floor.
- Wheel 66 defines a circular outer surface 68, and includes a central transverse passage through which an axle 70 extends.
- axle 70 extends outwardly from the outer side surface of wheel 68, and is received within a recess 72 formed in the inner surface of the lower section 56 of housing end wall 54.
- a suitable retainer such as a snap ring or the like (not shown), is engaged with the outer end portion of axle 70 to maintain axle 70 in engagement within the central transverse passage of wheel 66 within which axle 70 is received.
- Recess 72 has a width slightly greater than, and in closed tolerance to, the diameter of axle 70, and defines a vertically extending slot having an upper edge 74 and a lower edge 76.
- Housing 42 further includes a guide wall 78 that separates passage 46 of tubular mounting section 44 and inner portion 62 of the interior of housing 42.
- Guide wall 78 includes a vertical slot 80 having a width slightly greater than, and in closed tolerance to, the diameter of axle 70, and which defines an upper edge 82 and a lower edge 84.
- Guide wall slot 80 is in lateral alignment with recess 72, and is shaped similarly so that recess upper edge 74 and slot upper edge 82 are at generally the same elevation, and recess lower edge 76 and slot lower edge 84 are at generally the same elevation.
- the inner end portion of axle 70 extends through guide wall slot 80.
- the inner end portion of axle 70 that extends through guide wall slot 80 and inwardly of guide wall 78 is rigidly mounted to an axle carrier 86.
- Axle carrier 86 includes an arcuate lower edge 88 within which a recess 90 is formed, and which is configured to receive the inner end portion of axle 70.
- Axle carrier 86 and axle 70 may be rigidly interconnected in any satisfactory manner, such as by welding.
- Axle carrier 86 is a generally pllhlar Ai ⁇ Wer" 'Hfe ; ⁇ rt ⁇ nf Ift" ⁇ ltePsurface located adjacent and engaged with an inner surface defined by guide wall 78.
- Arcuate edge 88 of axle carrier 86 has a shape corresponding to that of the inner surface of the wall of housing mounting section 44.
- Axle carrier 86 further includes a pair of angled side edges 92 that extend inwardly from lower edge 88, and an upper edge 94 located between side edges 92.
- a retainer tab 96 extends upwardly from upper edge 94, so that upper edge 94 defines a pair of upwardly facing shoulders located one on either side of retainer tab 96.
- the inner surface of tubular mounting section 44 of housing 42 is formed so as to define a laterally facing shoulder 98 located outwardly of guide wall 78.
- a biasing member, in the form of a spring 100 bears between axle carrier 86 and the inner surface of the wall of mounting section 44 adjacent shoulder 98.
- Spring 100 is in the form of a coil spring having an internal passage, and retainer tab 96 of axle carrier 86 extends into the lower area of the passage of spring 100. With this construction, the shoulders defined by the areas of upper edge 94 adjacent retainer tab 96 engage the lower extent of spring 100. Spring 100 thus biases housing 42 upwardly relative to axle carrier 86, toward a position as shown in Figs. 2 and 3, in which axle 70 is in a lowered position in engagement with lower edge 76 of recess 72 and lower edge 84 of slot 80.
- Guide wall 78 includes a recess 102, which is configured to receive the outer portion of spring 110 that is located outwardly of axle carrier 86.
- each locking roller assembly 40 functions as follows to selectively fix chair and desk assembly 10 in position.
- each locking roller assembly 40 When a user is seated in chair section 12 of chair and desk assembly 10, the weight of the user applies a downward force to base assembly 28 through seat support pedestal 22. The downward force on base assembly 28 in turn applies a downward force to each locking roller assembly 40, which overcomes the upward biasing force of each locking roller assembly spring 100. For each locking roller assembly 40, the downward force functions to move the locking roller assembly housing 42 downwardly against the biasing force of each spring 100. Such downward movement of the housing 42 moves the engagement surface 60 downwardly toward and into engagement with roller outer surface 68, as shown in Fig. 4. Such downward movement of housing 42 relative to its associated wheel 66 is accommodated by recess 72 and slot 80, which enable axle 70 to remain stationary by virtue of engagement of outer surface 68 of wheel 66 with support surface S.
- inner portion 62 of the housing interior has a width only slightly greater than the width of roller 66, such that the sides of wheel 66 are located closely adjacent the outer surface of guide wall 78 and the inner surface of housing end wall lower section 56.
- engagement of roller outer surface 68 by engagement surface 60 causes slight lateral movement of wheel 66 due to the angle of engagement surface 60, which causes wheel 66 to shift toward and into engagement with guide wall 78.
- Engagement surface 60 thus wedges against roller outer surface 68, to prevent rotation of wheel 66 until the load on chair section 12 of chair and desk assembly 10 is relieved.
- the engagement surface defined by the end wall of the housing may be formed with any desired shape, e.g. a concave or convex shape, and is not limited to the planar configuration as shown and described.
- the housing has been shown as having a round or circular construction, it is also understood that the housing may be formed to have a square cross section, or any other shape.
- the biasing arrangement may be any type of biasing arrangement that urges the housing toward its raised position, and is not limited to the coil spring as shown and described.
- the axle carrier has been shown as being mounted only to one end of the axle, it is also contemplated that the axle carrier may be mounted to both ends of the axle.
- engagement surface has been shown as being defined by the inside surface of an end wall of the housing, it is also understood that the engagement surface may be defined by an internal surface of the housing that is in vertical alignment with the wheel. It should also be understood that the locking roller assembly of the present invention may be used in combination with any article of furniture that is capable of supporting a load, such as a table, desk, chair, stood or the like, and is not limited to use with a combination chair and desk as shown and described. Various alternatives and embodiments are contemplated as being within the scope of the following claims particularly pointing out and distinctly claiming the subject matter regarded as the invention.
