Definitions
- the present invention relates to a support cradle for bowling balls as defined in the preamble of claim 1 .
- a support cradle is conceived for use primarily in grinding, polishing and cleaning of bowling balls.
- the present invention has made it possible to develop a practical and handy support especially for bowling balls.
- the invention has the characteristics defined in claim 1 .
- the subsequent dependent claims define appropriate further developments and variants of the invention, which further enhance its function.
- the invention is based on the idea that, using a simple cup- shaped support, a bowling ball is maintained in the desired stable position during grinding, polishing or cleaning, and by contrast, when one wishes to turn the ball in the desired direction in order to be able to work all the parts of the surface, friction against the support surface is eliminated by lifting the ball by means of a compressed-air cushion or a fluid cushion.
- the support cradle has a very straightforward and economical design and it can, for example, be injection moulded in a single piece.
- the support cradle has no movable parts and it also has a very simple function.
- the support cradle is small-sized, light and requires small space during transport, use and storage.
- the support cradle is also suitable for passive use as a packing support, a storage support and as a display support in ball demonstrations and shows for sales purposes, for instance.
- Figure 1 shows an axonometric projection of a preferred embodiment of a support cradle for bowling balls
- Figure 2 shows a section of a support cradle in accordance with Figure 1 along the line A-A with a bowling ball placed in it,
- Figure 3 shows an axonometric projection of an embodiment of a support cradle for bowling balls with a dust exhaustion connection
- Figure 4 shows a section of a support cradle in accordance with Figure 3 along the line B-B with a bowling ball placed in it,
- FIG. 5 shows a construction detail in accordance with detail C in Figure 4 with a dust exhaustion duct
- Figure 6 shows an alternative construction detail at detail C of Figure 4 with a dust exhaustion duct and a brush connected to this.
- the special embodiment of the present support cradle 1 for bowling balls shown in the accompanying Figures 1 and 2 comprise a support surface 2, which is advantageously shaped as a spherical belt.
- This support surface is specially adapted for receiving a bowling ball 3.
- the support surface is carried by a frame 4 joining the upper edge 5 of the curved surface of the support surface via an outer support ring or rim 6.
- the support cradle comprises a bottom cup 7, which is disposed to join the support surface substantially tightly so as to form an impervious cup in this manner.
- the primary idea of the present support cradle 1 is its usability in grinding, polishing and cleaning of bowling balls 3.
- the ball is allowed to bear against the support surface 2 of the support cradle, and then friction between the ball and the support surface will principally prevent rotation of the bowling ball.
- the ball needs to be lifted from the support surface. This is done by producing an air cushion or a water cushion between the support surface 2 and the surface 8 of the bowling ball. Such an air cushion or water cushion makes the bowling ball rise from the support surface, thus eliminating friction against the support surface and allowing the bowling ball to turn virtually frictionless in any direction.
- the support cradle advantageously comprises a special connection 9 for compressed fluid, as shown in Figures 1 and 2. If the support surface 2 and the bottom cup 7 jointly form a substantially uniform hemispherical surface, this connection is preferably placed in the centre of the support surface or the cup formed by this. By contrast, if the bottom cup is slightly lowered relative to the support surface shaped as a spherical belt, as shown in the accompanying figures, the connection can be placed anywhere within the lowered part.
- connection 9 for compressed fluid is advantageously provided with means for pressure control and/or flow control.
- a means known per se may, for instance, consist of a pump, which may be a separate electrically driven pump, or a separate manually operated pump.
- the compressed fluid to be introduced in the support cradle 1 may consist of compressed air as well as of water.
- the compressed air can be advantageously utilised by connecting the compressed-fluid connection to a stationary compressed-air network.
- water is most conveniently utilised by connecting the compressed-fluid connection to a pressurised water distribution network.
- the spherical belt of the support surface 2 also adopts a shape that corresponds substantially to the geometry of the spherical surface 8 of the bowling ball 3.
- the support surface and the bowling ball fitted on this will thus together form a substantially tight connection, the compressed fluid introduced in the support cradle being disposed to form the required compressed-fluid cushion between the support surface and the bowling ball.
- a specially advantageous embodiment of the support cradle I is achieved, when the upper edge 5 of the support surface 2 has an outer diameter in the range 0.6 to 0.9 x the diameter of the bowling ball 3, preferably 0.8 x the diameter of the bowling ball.
- the support surface 2 in which the support surface 2 consists of a spherical belt, it should have a height H such that the curvature length it defines in the spherical belt exceeds the maximum diameter of the grip holes provided in the bowling ball 3. The purpose of this is to avoid air leakage as a grip hole passes by the support surface when the bowling ball is rotated.
- the central portion of the support surface 2, i.e. the bottom cup 7 connected to it, can be lowered relative to the spherical belt and the mean diameter of the bowling ball, so that the bowling ball bears only against the annular spherical belt forming the resulting support surface.
- Such lowering can advantageously be in the range 1 to 5 mm.
- a threshold 10 is consequently formed between the surfaces of the spherical belt and the bottom cup, respectively, as is shown in Figures 2 and 4. The lowering of the bottom cup will result in a gap
- This gap can be advantageously utilised for more effective distribution of the compressed fluid introduced in the support cradle.
- connection 9 of the support cradle 1 for compressed fluid is advantageously connected to an existing compressed-air network or a water pipe.
- the function can be controlled as necessary, for instance with the foot during grinding. It is also possible to use an appropriate foot pump, which is connected directly to the compressed-fluid connection of the support cradle.
- a portable electrically driven air compressor which can be operated by means of an appropriate foot valve in order to produce the air cushion under the ball when the ball needs to be turned.
- the pressure can, as necessary, be set so as to allow continuous turning and rotation of the ball.
- Water is used especially if it is desirable to carry out grinding as wet grinding, thus providing simultaneous wetting of the surface of the bowling ball during its rotation.
- the support can be provided with a ring 12 positioned outside the support surface 2.
- a ring 12 positioned outside the support surface 2.
- This ring may constitute a separate part, which can be readily connected to the frame of the support cradle in accordance with Figure 4.
- the ring may naturally also be formed as an integrated part of the support cradle.
- said ring 12 can jointly with the frame 4 of the support surface form a conduit 13 around and outside the support surface 2, the ring being disposed to seal against the surface 8 of the bowling ball fitted in the support cradle.
- Air and dust can be evacuated from the conduit by means of a dust exhaustion device or a separate dust cleaner, which is connected to a special connecting means 14 for such a device.
- the air that would normally blow dust from the ball surface out in the room will thus be captured by the exhaustion device and then filtered.
- the ring should be located close to the support surface in order to provide a narrow conduit. With a conduit having excessive width, depression will immoderately counteract the lifting force generated against the support surface.
- the ring 12 can advantageously also be provided with an annular brush 15, which appropriately seals against the surface 8 of the bowling ball 3 as shown in Figure 6.
