Definitions
- the invention relates to a wheel for a furniture roll with a locking device, with a rigid wheel core with a hub for receiving an axle and with an elastic wheel jacket as a tread, and a furniture roll with such a wheel.
- wheels with wheels with a hard tread for softer ground such as carpet
- wheels with wheels with a soft tread for harder ground such as parquet or stone.
- Both types of rollers can be equipped with a locking device.
- Wheels with a soft tread have a wheel core of a stiff material and a wheel casing of elastic material surrounding the wheel core.
- the determination of hard rollers and soft rolls with a larger diameter is usually carried out by means of a pivotally mounted on the roller body lever with two molded pins or an inserted steel pin, which dive in double wheels in a ring gear of the wheels and determine them.
- the object of the present invention is to provide a roller wheel with a soft tread and a diameter of less than 40 to 50 mm, which allows an effective and reliable wheel lock without slipping.
- the invention is based primarily on the recognition that for a safe and wear-resistant locking mechanism of the sprocket have the largest possible diameter and should consist of the hard material of the wheel core.
- the wheel has an inwardly facing toothing on an outer rim of the wheel core, wherein between the tooth flanks at least one opening in the outer ring is formed, in which an axially parallel, with respect to the tread radially inwardly offset web of the wheel shell engages positively.
- the locking device pivotally mounted on the roller body locking lever and arranged on the locking lever, engageable with the hub towards open recesses of the wheel core engageable locking element, in particular a molded onto the locking lever or inserted into the lever Pin, has, in an advantageous embodiment of the invention between each two teeth of the toothing a radially inwardly open recess for receiving the locking element of the locking device is formed. It is then expediently provided in each case an opening in the outer ring of the wheel core between two of the hub towards open recesses, so that a corresponding number of webs of the wheel jacket are formed and a good grip of the wheel jacket is ensured at the wheel core. Furthermore, the inwardly open recesses in the outer ring of the wheel core can have undercuts, in which the locking element of the locking device can be latched. A separate backup of the locking lever in the blocking position is then not required.
- the diameter of the wheel is less than 45 mm, in particular less than 40 mm.
- the wheel core can be made of metal or hard plastic and the wheel casing of elastically yielding plastic.
- FIG. 1 shows a side view of a wheel with a hard wheel core and elastic Radmantel
- Figure 2 is a section through the wheel along the line A-A in Fig. 1.
- Fig. 3 is a perspective view of the wheel of FIG. 1;
- FIG. 4 shows a perspective view of the wheel core of the wheel according to FIG. 1 without the wheel jacket
- Fig. 5 is a perspective view of the wheel jacket.
- a small diameter of less than about 45 mm having wheel consists essentially of a wheel core 10 of a hard plastic material or metal and an e- elastic wheel casing 12.
- Such wheels are arranged mainly in pairs on an axis of a double role ,
- the wheel core 10 has a hub 14 for receiving an axle and an outer rim 18 connected to the hub 14 via spoke-like connecting ribs 16.
- the outer rim 18 has a plurality of radially inwardly facing teeth 20, the radially inwardly open recesses 22 for receiving a locking element of a locking device of a wheel having the role limit.
- the teeth 20 have undercuts, so that the locking element can engage in the recesses 22.
- the teeth 20 further have tips 24, which laterally deflect the locking element in the corresponding relative position in the direction of a recess 22 or provide for a corresponding rotation of the wheel.
- the outer ring 18 has openings 26 (FIG. 4) in the area of the teeth 20, which are penetrated by axially parallel webs 28 (FIG. 5) of the wheel jacket 12 enclosing the wheel core 10.
- openings 26 FIG. 4
- each tooth or at least a major part of the teeth has such an opening 26.
- the webs 28 of the wheel jacket 12 are formed automatically when spraying the wheel jacket in the corresponding number of openings 26. If the apertures in the drawing are shown as through openings, this should not exclude that a sufficient anchoring of the wheel jacket 12 on the wheel core 10 is not possible by more or less pronounced depressions in the teeth 20 and in this engaging projections of the wheel jacket 12 is.
- the wheel core 10 consists of a hard material compared to the wheel casing 12, so that the wheel-side part of the locking device is mechanically durable and durable.
- the invention relates to a wheel for a furniture roll with a locking device, with a rigid wheel core 10 with a hub 14 for receiving an axle and with an elastic wheel jacket 12 as a tread.
- an inwardly facing toothing 20 is provided on an outer rim 18 of the wheel core 10, wherein at least one opening 26 is formed in the outer rim 18 between the tooth flanks, into which an axis-parallel aligned, with respect to the tread radially inwardly offset web 28 of the wheel jacket 12 engages positively.
