Description

Hose Reel Spool {HOSE REEL SPOOL}

Filed under the same application as inventor of the present invention by inventor Anthony Shakal and John Holman and entitled “Hose Reel Frame and Guide Arm”, and filed and invented by the inventor Anthony Shakal and Scott Hill as the same as this application Reference is made to regular application No. _ with the name "Hose Reel Latch".

The present invention relates generally to hose reels and in particular to hose reel spools having sides that hold the hose on the spool.

Hose reels are commonly used to integrate fluid carrying hoses. Wrapped hoses take up less space and become less entangled with the surroundings. Industrial hose reels often serve as counterweights that allow them to be automatically wound in the absence of expansion force on a hose biased by a torsion spring or attached to the reel.

Hose reels usually include three main components, the spool, the frame and the guide arm. The hose reel spool typically includes a hub having a cylindrical wall and axial facing sidewalls. The side wall and the cylindrical wall together form an annular retention zone in which the wound hose is stored. The fixed end of the hose generally passes through the cylindrical wall or is attached to a hose mount on the cylindrical wall. These hose mounts are usually angled to prevent excessive bending of the hose as it is wound around the spool. Many hose reels also include a frame or stand that supports and secures the spool. Such frames may be attached to one or both sides of the spool. The hose frame must be able to support the total weight of the spool that hangs on the hose as well as any stress associated with winding and unwinding the hose. Some hose reels also include guide arms that direct the hose to the spool by directing spooling of the hose. Like the frame, the guide arm can be attached to one or both of the hose reels. Most guide arms are rotatably attached so that the hose can be wound or unwound at various angles.

In the past, some hose reels have included a ratcheting latch assembly to rewind the hose or prevent the hose reel from returning during use. These latch assemblies typically include a pawl on one of the hose reel frame or guide arm and a toothed ratchet element secured to one side of the spool. Previous hose reels typically included pole mounts on either frame or guide arm, but not both, due to increased cost and manufacturing time requirements. The pawl engages with the ratchet to limit the rotation of the spool, thereby preventing winding. In the case of such a latch assembly, the latched hose is returned by first loosening the hose slightly so that the ratchet element is separated from the pawl. This may present difficulties if the pawls engage while the hose is fully loosened. In such cases, it may be impossible to unlatch and re-spool the hose without disassembling the hose reel. This makes it possible to ensure that this situation is never caused by fabricating the ratchet element from the hose mount on the radially opposite side of the spool and installing the pole on the guide arm. When the hose is not fully loosened, the hose mount will be radially aligned with the guide arm. As a result, the pawl mounted on the guide arm can never engage with the ratchet element on the opposite side of the hose mount while the hose is fully extended. This solution is not available if the hose reel does not include a guide arm. In applications where the guide arm is omitted to save cost, weight, or space, the ratchet should not be mounted elsewhere or fired at all.

Hose reels are preferably strong, compact, and easily assembled. In the past, hose reel frames were often constructed by supporting flanges extending axially outward, and hose reel spools were often constructed by dished side walls that were axially outwardly inclined. Such configurations provide additional strength, but are larger than flat spools and thus require larger frames with larger volumes. Ease of assembly is important during and after fabrication. In particular, it is desirable for the hose reel to be easily adapted to different operating conditions and applications.

The present invention relates to a hose reel spool with two concave dish side walls bracketing a cylindrical wall. The side walls are angled inward axially so that they converge toward each other as they extend radially outward.

Ⅰ. summary

1A and 1B show a frame [with side walls 108a, 108b], a frame [with frame base 26 and a frame side 26 with flange 30 and studs 29 and 28, 28b] 14, guide arm 16 (each with L-shaped part 32 and I-shaped part 34 with holes or teeth 31), hose 18, hole 20, anchor 22 , Hose reel assembly 10 including mounting hardware 23, ratchet element 24, and a pole (shown in broken line behind guide arm 16). 1A and 1B also show the winding direction W and the unwinding direction UW. The spool 12 rotates to wind and unwind the hose 18 wound around the central cylindrical surface and between the sides of the spool 12.

Spouse 12 includes an axial hub 104 and a radially extending first side wall 108a and a second side wall 108b (not visible in FIG. 1A or 1B; see FIG. 2). As shown, the spool 12 rotates in the winding direction W to wind the hose 18 and in the unwinding direction UW to unwind the hose. In other embodiments, the spool 12 may be fabricated to wind and unwind the hose 18 in the opposite direction. The frame 14 supports the spool 12 and the guide arm 16. Guide arm 16 extends from frame 14 to hold hose 18 as shown. The spool 12 may in some embodiments be mounted to the mounting hardware 23, which is a central shaft or pin that extends through the spool 12, the frame sides 28a, 28b, and the components 32, 34 of the guide arm 16. Thereby rotatably attached to the frame 14. In one embodiment, the spool 12 is biased (eg by a torsion spring) to rotate in the winding direction W when there is no opposite force, thus winding the hose 18. Sides 108a and 108b of the spool 12 are angled axially as they extend radially outward, where the side 108a is angled towards and vice versa 108b. This angled configuration reinforces the spool 12 and prevents contact between the side walls 108a and 108b and the flange 30 (described below).

Frame 14 includes a horizontal frame base 26 and vertical frame sides 28 and 28b. Frame sides 28, 28b are secured to frame base 26, which forms the basis of frame 14. Frame sides 28a and 28b are welded to frame base 26 to form an L-shaped frame part. The frame side 28b is not welded to the frame base 26 but is fastened to the frame base 26 when the frame 14 is assembled. The L-shaped component comprising the frame side 28a and the frame base 26 is combined with the frame side 28b to form a U-shaped portion of the frame 14. Frame sides 28a, 28b support spool 12 and guide arm 16 through mounting hardware 23, as discussed previously. The base 26 does not extend axially wider than the guide arm 16. Frame sides 28a and 28b engage flange 30 to reinforce frame 14. The flange 30 is located on the inner side of the frame side 28a, 28b and is widest at the frame base 26 and vertically tapered to the frame side 28a, 28b. Since the flange 30 is located on the inner side of the frame sides 28a and 28b, the flange 30 does not provide additional width to the hose reel 10. As previously discussed, the sides 108a, 108b of the spool 30 are inclined axially inward toward each other, so that contact with the flange 30 is prevented.

Guide arm 16 is also attached to frame 14 and rotates about the axis of spool 12 independently of spool 12. The guide arm 16 is attached directly to the frame 14 via one or more fasteners, or fixed to the frame 14 by mounting hardware 23. In one embodiment, the studs 29 are arranged in a circular arrangement on the frame 14 and are coupled with holes or teeth 31 in the guide arm 16 to secure the guide arm 16 in a predetermined angle range. The free end of the hose 18 passes through the hole 20 in the guide arm 16, but due to the anchor 22 on the hose 18, which is too large to fit through the hole 20, the spool 12 I cannot fully retreat with). The anchor 22 may be a rubber or plastic block fixed around the hose 18. The guide arm 16 consists of two parts, an L-shaped part 32 comprising one side and a front side of the guide arm 16 and an I-shaped part 34 comprising an opposite side of the guide arm 16. It is composed. L-shaped component 32 and I-shaped component 34 are fastened together to form guide arm 16, as shown.

The ratchet element 24 is secured to the spool 12 and borders the pawl 25 on the guide arm 16 to prevent the hose 18 from being unreasonably retracted. The ratchet element 24 consists of only a partial radial arc of the spool 12 as shown, so it is only aligned with the pawl 25 for each partial rotation of the spool 12. When the ratchet element 24 rotates in the UW direction to align with the pawl 25, the pawl 25 engages the ratchet element 24 and exerts a relative rotational force that prevents rotation of the spool 12 in the W direction. . When the ratchet element 24 is not aligned with the pawl 25, or rotates in the W direction to align with the pawl 25, the pawl 25 does not catch on the ratchet element 24, or the spool 12 It does not prevent rotation in either direction. Although pawl 25 is shown mounted to guide arm 16 in FIG. 1A, pawl 25 may alternatively be mounted to frame 14.

Ⅱ. Spool (12)

2 shows an axial hub 104 (with an outer cylindrical wall 106 with a hose mount 112), a side wall 108a (with an outer annular lip 118a), and an outer annular lip. Front view of spool 12 (with spool halves 102a, 103b) including side wall 108b] (with 118b and annular ridge 114). The outer cylindrical wall 106 and the side walls 108a and 108b together form an annular hose retention area 110.

As mentioned previously, the spool 12 consists of an axial hub 104 and side walls 108a, 108b. The axial hub 104 includes an inner end wall 120 (not visible in FIG. 2 and visible in FIG. 3) and an outer cylindrical wall 106. The outer cylindrical wall 106 is the radially outermost cylindrical portion of the axial hub 104. The side walls 108a and 108b are annular flanges extending radially outward from the edges of the outer cylindrical wall 106. Together with the side walls 108a and 108b, the outer cylindrical wall 106 forms a hose retention area 110 which is an annular space in which the hose 18 is wound for storage. In one embodiment, the spool 12 is formed of two halves. The first spool half 102a includes a first side wall 108a and an outer cylindrical wall portion 106a. The second spool half 102b includes a second side wall 108b and an outer cylindrical wall portion 106b. The spool 12 is formed by welding or screwing together the first spool half 102a and the second spool half 102b.

The hose 18 is mounted to the hose mount 112 of the outer cylindrical wall 106 inclined counterclockwise so as not to excessively bend the hose 18 connected to the hose mount 112. In one embodiment, the hose mount 112 is a passageway through the cylindrical wall 106 through which the hose 18 is screwed. In another embodiment, the hose mount 112 is an attachment point for one end of the hose 18, and the axial hub 104 further has a connection device for circulating fluid from the fluid source into the hose 18. Include. In one embodiment, ratchet element 24 is mounted radially opposite from hose mount 112 to prevent locking of ratchet element 24.

When the hose is wound on the spool 12 through the hole 20 of the guide arm 16 (see FIGS. 1A and 1B), the outer cylindrical wall 16 has a pyramid shape no more than four times the hose width. It is naturally wound and stacked up and generally narrower when stacked radially outward. Therefore, the outer cylindrical wall 106 is designed to be slightly larger than four times the width of the hose, because the width beyond that can increase the size of the hose reel assembly 10 without gain.

The annular ridge 114 extends axially outward from the outer cylindrical wall 106 to provide a radially flat surface for attachment of a cover (not shown) to the spool 12. The annular ridge 114 is described in more detail in conjunction with FIG. 3. The side walls 108a and 108b are inclined axially inward as they extend radially outward, with the side walls 108a being inclined toward the side wall 108b and vice versa. This inclined configuration strengthens the spool 12 without increasing the spool width.

3 is a side view of a spool 12 showing an annular ridge 114, a mounting hole 116, an outer annular lip 118b, an inner end wall 120 with a mounting position 122, and a ratchet element 24. to be. As previously discussed, the axial hub 104 includes an inner end wall 120 and an outer cylindrical wall 106. The inner end wall 120 is a flat radial surface that spans the inside of the spool 12 radially inward of the cylindrical wall 106 (see FIG. 2). The inner end wall 120 also includes a mounting location 122. The mounting hardware 25 is fixed in the mounting position 122 to support the spool 12 on the frame 14. In one embodiment, the mounting hardware 24 is a shaft or pin, and the mounting position 122 is a passageway through the inner end wall 120 through which the mounting hardware is fitted. Mounting position 122 is described in more detail later.

The annular ridge 114 is the area of the side wall 108b in which the mounting hole 166 is perforated. The aperture 116 allows the cover (not shown) to be screwed or riveted to the side wall 108b, if desired, at the annular ridge 114. The annular ridge 114 is located at one end of the outer cylindrical wall 106 and extends directly radially outward from the outer cylindrical wall 106 to provide a flat mounting surface for the cover. An annular ridge 114 is shown on the side 108b, but may instead be located on the side 108a.

The radially outer extensions of the side walls 108a and 108b pivot axially outward in the outer annular lips 118a and 118b, which reinforce the spool 12. The second side wall 108b terminates at the second outer annular lip 118b, which is pivoted away from the hose retention region 110 and the first side wall 108a. Similarly, the first side wall 108a (not visible in FIG. 3, see FIGS. 2 and 4) terminates in the first annular lip 118a, which is the hose holding area 110 and the second side wall ( Pivot axially away from 108b). Since the side walls 108a and 108b are inclined inward axially as they extend radially outward, the outer annular lip 118 is not added to the full width of the spool 12. Ratchet element 24 is threaded or riveted to side wall 108b to interact with pawl 25, as discussed previously. 3 also shows a cross line 4-4 passing through the spool 12.

4 is an exploded cross-sectional view of the spool 12 along the transverse line 4-4 of FIG. 3. 4 shows the outer cylindrical wall 106, the side walls 108a, 108b, the outer annular lips 118a, 118b, the inner end wall sections 120a, 120b and the mounting section 122, the collar 124, and the holes. Spool 112 is shown including 126. 4 shows disassembled spool halves 102a and 102b for clarity. When the spool 12 is assembled, the spool halves 102a and 102b are attached together as previously discussed. Mounting hardware 25 secures spool 12 to frame 14 by passing through mounting position 122.

In the embodiment where the spool 12 is formed of two halves, the inner end wall 120 has two abutting sections, namely a first inner end wall section (which is part of the first spool half 102a). 120a) and a second inner end wall section 120b (which is part of the second spool half 102b). These sections are bolted or welded together to connect the spool half 102a to the spool half 102b. In one embodiment, the first inner end wall section 120a includes a hole 126 and the second inner end wall section 120b includes a collar 124. Hole 126 is a central hole in second inner axial end wall section 120a and large enough to receive collar 124. The collar 124 is the central axially extending portion of the second inner axial end wall section 120b that passes through the hole 126 to form a journal for the mounting hardware 25. In other embodiments, the position of the collar 124 and the hole 126 can be changed, wherein the collar 124 is located in the first inner end wall section 120a, while the hole 126 is in the second inner end. It is located in the wall section 120b. Bushings or bearings are inserted in the collar to support the spool 12 as it rotates.

As previously discussed, the side wall 108 is inclined axially inward as it extends radially outward for further reinforcement. This inward inclination is designed to match the aforementioned natural pyramid stacking profile of the aperture 18 around the annular ring 106 and thus does not interfere with spooling. The radially outermost edge of the first side wall 108a terminates at the first outer annular lip 118a, and the radially outermost edge of the second side wall 108b terminates at the second outer annular ridge 118b. do. The outer annular ridges 118a and 118b further strengthen the spool 12.

4 also shows an area R comprising a section of the outer cylindrical wall 106 and a second side wall 108b.

5 is an exploded view of the region R of FIG. 4. 5 shows a side wall 108B, an annular ridge 114, and one mounting hole 116 with a portion of the inner annular ring 106 and an outer annular lip 118B. The annular ridge 114 does not tilt the side wall 108b axially inward over the entire radial enlargement from the intersection of the inner annular ring 106b and the side wall 108a to the outer annular lip 118a. It is formed by directly extending the side wall 108b a short distance radially outward from the outermost enlargement of the cylindrical wall 106. The spool cover may be attached to the side wall 108b by bolts passing through the mounting holes 116. As can be seen in FIG. 5, the axial inward inclination of the second side wall 108b prevents the second outer annular lip 118b from being added to the axial size of the spool 12. This also applies to the first side wall 108a and the first outer annular lip 118a. This compact design also allows the flange 30 to be oriented inward axially (as described above with respect to FIG. 1) without contacting the side walls 108a and 108b, thereby allowing the overall axis of the hose reel 10 to be oriented. Reduce the direction size further.

Ⅲ. Frame (14)

FIG. 6 is a top view of the frame base 26 of FIG. 1 showing the fastening tab 202, the ridged surface 204, the first side attachment area 206, and the second side attachment area 208. Frame base 26 is, in one embodiment, a pressed or cast metal sheet. The frame side 28a is welded to the position of the first side attachment area 206. The frame side 28b is attached to the frame base 26 at the second side attachment area 208 via a fastener threaded through the fastening tab 202. The fastening tabs 202 are stamped from the frame base 26 and bent 90 degrees from the frame base 26 in one embodiment and project parallel to the frame side 28b. In another embodiment, the fastening tab 202 is a separate metal part that is welded to the frame base 26. Ridged surface 204 is an elevated area that reinforces frame 14 against bending by pressing or casting to frame base 26.

7A and 7B are, respectively, an outer side view and a front view of the frame side 28a and the frame base 26 connected to form an L-shaped component. FIG. 7A shows frame side 28a, mounting point 210a, ridge 212a, and stud 29 with frame base 26 and flange 30a. 7B shows frame base 26 with ridged surface 204, fastening tab 202 (with fastener holes 214), and frame side (with frame 30a and studs 29). 28a, mounting hardware 23 is attached to or transported through mounting point 210a to secure spool 12. Mounting hardware 23 is for example an axle or If it is a shaft, the mounting point 110a is a hole and through it the mounting hardware 23. As previously described, the flange 30a reinforces the frame 14 and supports the side 108a. 6. The flange 30a is inclined inwards diagonally inward toward the inside of the hose reel assembly 10, as indicated by the first side attachment point of Fig. 6. The ridge 212a is frame side 28a with respect to bending. As shown in Figure 2A, the ridge 212a includes corrugations extending to the side 28a. C. The fastening tab 202 has a fastener hole 214 that allows the threaded fastener to pass through the fastening tab 202 to secure the frame side 28b (see FIGS. 1A and 1B). ) Helps to secure the guide arm 16 to the frame 14, as described later in connection with FIGS. 10A-10D.

FIG. 8 is an outer side view of frame side 28b showing flange 30b, mounting point 210b, ridge 212b, and fastener holes 214b. Flange 30b and ridge 212b reinforce frame side 28b as if frame 30a and ridge 212a reinforce frame side 28a. Mounting hardware 23 is attached to or transported through mounting point 210a to connect spool 12 to both sides of frame 14. Fastener holes 214b in the flange 30b allow the frame side 28b to be mounted on the fastening tab 102. Fastener 216 (not shown in FIG. 8; see FIG. 9) passes through fastener hole 214 to secure frame side 28b to frame base 26 to secure frame side 28b. It is held within the side attachment area 208 of FIG. Fastener 216 may be a bolt, screw, or other toothed fastener.

9 includes frame base 26, frame sides 28a, 28b (with mounting points 210a, 210b, and studs 29, respectively), fastener holes 214, and fasteners 216. It is a perspective view of the frame 14 shown. As previously discussed, frame side 28a is welded to frame base 26 to form an L-shaped component. The frame side 28b is attached to this L-shaped component by inserting the fastener 216 through the fastener hole 214a (not shown), 214b. This configuration simplifies the mounting of the spool 12 (via the mounting hardware 23 attached to or transported through the mounting points 210a, 210b). The frame sides 28a and 28b lock the spool 12 together in place when the frame side 28b is fixed in place (leave the spool 12 free to rotate). Installation or removal of the spool 12 releases the fastener 216 from the fastener hole 214, removes the mounting hardware 23 from the mounting point 210b, and the frame base 26 and the mounting hardware 23. By separating the frame side 28b. The studs 29 interact with the teeth or holes 31 (see FIGS. 1A and 1B) to hold the guide arm 16 in place relative to the frame 14.

IV Guide Arm (16)

10A-10D show the L-shaped component 32 of the guide arm 16. 10A, 10B, 10C, and 10D are views of the inside, front, top, and outside of the L-shaped component 32, respectively.

L-shaped component 32 includes side section 302 [with ridge 308, attachment area 310, pole mount 402b, spring mount 404b, and hole 31], [front hole 312]. Front section 304 and side tabs 306 (with fastening holes 318). The L-shaped component 32 is attached to the I-shaped component 34 by screwing the fastener 322 (see FIG. 12) into the fastener hole 320 through the L-shaped component 32. Ridge 308 extends the length of side section 302 and stiffens guide arm 16 against bending. As shown in FIG. 10A, the ridge 308 includes corrugations extending into the side section 302.

Guide arm 16 is attached to frame 14 at attachment area 310. In one embodiment, the hole 31 on the guide arm 16 receives the studs 29 on the frame 14. The studs 29 and the holes 31 are arranged in a circular arrangement and hold the guide arm 16 in place at any predetermined angle range relative to the spool 12. When the L-shaped component 32 is attached to the I-shaped component 34, the guide arm 16 can rotate at separate angular intervals around the axis of the spool 12 (formed by the mounting hardware 23). In this case, the stud 29 supports the guide arm 16 in a preferred position. In some embodiments, guide arm 16 may be additionally or alternatively supported by a clip or bolted fastener, or may be secured in place by mounting hardware 23.

The hose 18 is limited by a guide arm 16 that restricts access of the spool 12 from a defined angular range by passing through the front hole 312. This forces the hose to be wound on the spool 12 in a regular and tight manner and prevents harmful forces from being applied to the spool 12 or the frame 14.

The pawl 25 (see FIGS. 1A and 1B) is attached to the guide arm 16 or the frame 14 to inhibit rotation of the spool 12. Pole mount 402b is one mounting position for pole 25 and spring mount 404b is one mounting position for a spring (not shown) that holds pawl 25 relative to ratchet element 24. The interaction of the pawl 25 and the ratchet element 24 of the pawl is described in more detail with reference to FIGS. 13A-15B.

11A and 11B show an I-shaped component 34 of the guide arm 16. 11A is an outer side view of the I-shaped part taken along lines 11b-11b. 11B is a cross sectional view of the I-shaped part taken along lines 11B-11B.

The I-shaped component 34 has a ridge 308, an attachment region 310, a fastener hole 320, a fastener 322, and a hole 31. The I-shaped component 34 is attached to the L-shaped component 32 by fixing the fastener 322 through the fastener holes 318 and 320. In this way, the L-shaped component 32 and the I-shaped component 34 are joined together to form a U-shaped guide arm 14. Like the L-shaped component 32, the I-shaped component 34 is attached to the frame 14 at the attachment area 310 and engages the ridge 308 for additional strength as shown. As shown in FIG. 11A, the ridge 308 includes corrugations protruding from the I-shaped component 34. The hole 31 interacts with the stud 29 as described above to hold the guide arm 16. The I-shaped part 34 is similar to the side section 304 of the L-shaped part 32, but has a side pole mount 402b and a spring mount 402a present on the side section 304 of the L-shaped part 32. )

12 is a perspective view of assembled guide arm 16 showing L-shaped component 32, I-shaped component 34, attachment area 310, fastener hole 320, and fastener 322. As previously discussed, the guide arm 16 is assembled by fastening the L-shaped component 32 and the I-shaped component together. As in the frame 14, this configuration simplifies the mounting of the spool 12. That is, the installation or replacement of the spool 12 only requires the separation of the type I component 34 and the type I frame component 28b during removal or replacement of the spool 12.

Although frame 14 and guide arm 16 have been described as substantially symmetrical U-shaped structures, they can alternatively be fabricated as L-shaped asymmetrical parts. In such an embodiment, the frame 14 does not include the frame side 28b and the guide arm 16 does not include the I-shaped component 34. The frame 14 is attached to the spool 12 and guide arm 14 on only one side, so that the mounting hardware 23 is asymmetrical pin or cantilevered rather than a shaft or shaft supported on both sides of the spool 12. It must be a (cantilevered) shaft. This embodiment uses some frame strength for simpler installation and removal of the spool 12.

Ⅴ. Ratchet Assembly 400

FIG. 13A is a partial perspective view of the hose reel assembly 10 showing the guide arm 16 and the frame 14 with the parts removed and the spool 12 removed. The side 28a of the frame 14 is not shown and only a portion of the L-shaped part 32 of the guide arm 16 is shown. 13B and 13C are side views of FIG. 13A. FIG. 13B shows the pawl 25 mounted on the frame 14, while FIG. 13C shows the pawl 25 mounted on the guide arm 16. The frame 14 includes a base 26 and a visible side 28b with a pole mount 402a and a spring mount 404a. Guide arm 16 includes attachment location 310 and visible L-shaped component 32 (with pole mount 402b and spring mount 404b). Ratchet assembly 400 includes spring 408, bolt 410, and pawl 15 and may be attached to either frame 14 or guide arm 16.

Guide arm 16 is attached to frame 14 at attachment location 310. In one embodiment, the mounting hardware 25 extends through the attachment location 310 to secure the guide arm 16 to the frame 14. In another embodiment, the guide arm 16 is attached to the frame 14 by one or more pins. As discussed in connection with FIGS. 1A and 1B, the stud 29 may secure the guide arm 16 relative to the frame 14.

Either of the frame 14 and the guide arm 16 may mount the ratchet assembly 400. The pawl 25 may be mounted on the frame 14 or guide arm 16 by inserting a bolt 410 through the pawl 25 through the pawl mounts 402a and 402b, respectively. The pawl 25 engages the ratchet element 24, as previously discussed, to stop the rotation of the spool 12. The spring 408 is spring 25 (when pole 25 is mounted on frame 14) or spring mount 404a or pole 25 is mounted on guide arm 16. It is attached to mount 404b. Spring mounts 404a and 404b are attachment points that secure one end of spring 408. In one embodiment, the spring mounts 404a and 404b are stamped tabs that are bent from the frame 14 and the guide arm 16, respectively. By stretching the pawl 25 and the spring mounts 404a, 404b, the spring 408 is adapted to retain the pawl 25 associated with the ratchet element 24, as further described in connection with FIGS. 15A and 15B. A counter rotating force is applied on the pawl 25.

While pole mounts 402a and 402b are shown on side 28a and L-shaped component 32, respectively, pole mounts 404a and 404b are equivalent on side 28b and I-shaped component 34, respectively. Can be located. However, the attachment positions 402a, 402b, 404a, 404b may all be located on the side of the same hose reel assembly 10 as the ratchet element 24.

14A is a front view of the pawl 25 taken along lines 14b-14b. 14B is a cross sectional view of the pawl 25 taken along lines 14b-14b. 14C is a perspective view of pawl 25 with an exploded bushing 418 (described below). 14A, 14B and 14C show a pawl 25 comprising a pawl body 412 and bushing 418 with a pin hole 414, a tip 415, a spring hole 416 and a pocket 417. Illustrated. The pole body 412 is formed of cast metal in one embodiment. Tip 415 is a substantially triangular tip of pawl body 412, with a wide edge for holding ratchet element 24. In order to save material and reduce weight, all pole bodies 412 are not as wide as the tips 415, and as can be seen in FIG. 14A, the pole bodies 412 are the size of the poles 25 without the narrow tips 415. Flanges are formed in the pocket 417 to reduce the pressure. Tip 415 engages the teeth on ratchet element 24 as described in connection with FIGS. 15A and 15B. Bushing 418 is inserted between bolt 410 (see FIGS. 13A and 13B) and pawl body 412 to allow pawl body 412 to rotate smoothly on bolt 410. Bolt 410 passes through bolt hole 414 (see FIGS. 14A, 14B, and 14C) to pole mount 402a on frame 14 or pole mount 402b on guide arm 16. Secure (25). Spring 408 is attached to pawl 25 at spring hole 416. The pawl 25 may be mounted to either the frame 14 or the guide arm 16, as shown in FIGS. 13A and 13C.

15A and 15B show the pawl 25 in engagement with the ratchet element 24. 15A and 15B show ratchet element 24, pole 25 (with pole body 412 and spring hole 416), spring mount 404, spring 408, and bolt 410. Illustrated. The spring mount 404 may be either a spring mount 404a or a spring mount 404b. As previously discussed, bolt 410 mounts pawl 25 on either frame 14 or guide arm 16. The spring 408 extends between the spring hole 416 in the pole body 412 and the spring mount 404a or 404b. The pawl body 412 contacts the ratchet element 24 and rotates around the bolt 410 when stretching the spring 408 such that the spring force tends to hold the pawl 25 relative to the ratchet 24. . Whether the ratchet element 24 and the ratchet pawl 25 engage to prevent rotation in the W direction depends on the direction in which the ratchet element 24 is rotated in engagement with the pawl 25. This direction determines whether the pole 25 is inclined toward the UW direction (as in FIG. 15A) or toward the W direction (as in FIG. 15B).

15A shows the pawl 25 rotated in the UW direction in alignment with the ratchet element 24. Thus, the pawl 25 is engaged with the teeth of the ratchet element 24 to prevent the spool 12 from rotating in the W direction as long as the ratchet element 24 remains aligned with the pawl 25. will be. FIG. 15B shows the pawl 25 aligned with the ratchet element 24 and rotated in the W direction. The angle of the tooth of the ratchet element 24 relative to the pawl 25 prevents the pawl 25 from engaging on the ratchet element in FIG. 15B. When the pawl 25 is engaged on the ratchet element (FIG. 15A), the pawl 25 rotates the spool 12 in the UW direction until the ratchet element 24 is no longer aligned with the pawl 25. And the spool 12 can rotate freely in the W direction without the pawl 25 being engaged with the ratchet element 24 (FIG. 15B). This functionality is the same whether the pawl 25 is mounted on the frame 14 or the guide arm 16.

When the hose 18 is fully extended from the spool 12, the hose 18 extends directly from the hose mount 112 into the hole 20 in the guide arm 16 (see FIGS. 1A and 1B). By mounting the ratchet element 24 on the side of the spool 12 which is radially opposed from the hose mount 112, the ratchet element 24 is thus guided by the guide arm 16 while the hose 18 is fully extended. It is possible to ensure that it is never sorted with. When the pawl 25 is installed on the guide arm 16 (at the ratchet mount 402b), the spool 12 is never latched into an unlatched position due to lack of play in the hose. For this reason, it is advantageous to mount the pawl 25 on the guide arm 16.

However, the guide arm 16 may not be used for some applications. In such a case, the pawl 25 may not be mounted on the guide arm 16 and should instead be mounted on the frame 14. Although the frame 14 is in a less desirable position for the pawl 25 than the guide arm 16 for the reasons described above, the frame 14 is an acceptable alternative position for the pawl 25.

VI. conclusion

The hose reel described herein provides several advantages. Riding on the frame 14 and guide arm 16 strengthens the hose reel 10 against bending, and the inward flanges 30 provide stability and strength without increasing the size of the hose reel. The spool shape of the present invention minimizes size and improves durability without limiting hose movement by allowing use of the natural laminated profile of the wound hose. The axially inwardly inclined sides of the hose reel spool 12 increase the strength without additional spool width for a strong and compact hose reel assembly and despite the axially inwardly supporting flange 30 the spool 12 has a frame 14 ) Can be mounted on the

Configuring frame 14 and guide arm 16 from L-shaped and I-shaped components simplifies assembly of hose reel 10 and allows easy access to spool 12. The spool 12 can be removed by unscrewing the fastener 322 from the guide arm 16 and the frame 14, respectively, and detaching the mounting hardware 23 from the mounting point 310. The I-shaped part 34 and the frame side 28b are then removed, allowing the spool 12 to be detached from the fastening hardware 23. Installation of the spool 12 follows the reverse procedure. That is, the spool 12 is first attached to the fastening hardware 23, and then the frame side 28b and finally the I-shaped part 34 are respectively formed by the fasteners 216 and 322, the base 26 and the L-shaped. In place on the component 32.

By providing attachment points for the pawls 25 and the springs 408 on the guide arm 16 and the frame 14, the present invention allows the hose reel 10 to be positioned in any case while enabling optimal ratchet positioning. It may be used or not used for the guide arm 16. Ratchet assembly 400 is ideally fabricated whether attached to guide arm 16 or frame 14. The user removes the bolt 410 from the pole mounts 402a and 402b and separates the spring 408 from the spring mounts 404a and 404b, thereby moving the ratchet assembly from the frame 14 to the guide arm 16 or vice versa. Allows quick and easy exchange
