Abstract
A baffle located within a receptacle for liquid to control surging particularly suitable for use with firefighting vehicles having a water supply wherein the baffle is formed of polymeric intersecting longitudinal and transverse plate members having intermeshing slots and reinforcing inserts located in each plate member receive the end region of the intersecting plate member to support the end regions against deformation and displacement.
Description
1 The invention pertains to baffles located within liquid 2 receptacles to control surging, and particularly pertains to 3 baffles formed of polymeric material capable of being easily 4 assembled and reinforced.
Many types of firefighting vehicles utilize a water storage 6 tank or receptacle for dispensing water upon the fire. Such 7 tanks upon large firefighting vE~hicles may have capacities of 8 several hundred gallons and for :safety and other reasons, it is 9 common to baffle the interior of water receptacles on firefighting vehicles to control surging due to forces imposed 11 upon the water during vehicle movement.
12 Commonly, the baffles within firefighting vehicle tanks 13 consist of longitudinal and transverse plate members located 14 within the water tank or receptacle to divide the capacity into smaller "cells". Adjacent cells are in communication with each 16 other by openings or passages of such dimension as to prevent 17 objectionable transfer of water between adjacent cells during 18 surging, but are large enough to permit the water from all of 19 the cells to be utilized during water pumping.
The fabricating of water baffles is complicated and time 21 consuming in that extensive welding of intersecting plate 22 members is required, and in the event that the water receptacle 23 and baffles are damaged during a vehicle collision, the repair 24 of the water tank and baffles is expensive and time consuming.
It is known to form water tank baffles for firefighting vehicles 26 of polymeric material such as polypropylene or polyethylene, but 27 such baffles also require welding with a polymeric material, and 28 the repair of such polymeric baffles is very difficult as the 29 welds must be cut out and repaired.
The invention provides a polymeric baffle system for water 31 tanks which is easily assembled, requires a minimum of welding, 32 is effective to control surging, and is easily repairable. The 33 invention provides a baffle for liquid receptacles entirely formed _ 1 of polymeric material which minimizes the welding of the baffle 2 components by polymeric welding or solvents. Additionally, the 3 invention provides a baffle for liquid receptacles entirely formed 4 of polymeric material wherein a plurality of intersecting longitudinal and transversely disposed plate members utilize slots and reinforcing inserts to produce high strength mechanical 8 interconnections between assembled plate members simplifying 9 initial assembly, and simplifying disassembly in the event of lU required repair.
11 While it is possible to form the baffle of the invention by 12 using metal components, preferably, the baffle components are 13 formed of a non-corrosive, high strength, polymeric material 14 such as polypropylene or polyethylene, and the tank or receptacle, itself, may be formed of such polymeric material.
16 The purpose of the water b<~ffle of the invention is to 17 prevent water surging within the water tanks commonly carried by 18 firefighting vehicles. Fire trucks are subjected to rapid 19 starts and stops, sharp turns, and are often driven over uneven terrain. Such movements will cause the water within the water 21 tanks to surge temporarily changing the center of vehicle 22 gravity producing an uncomfortable ride, and at times, even 23 threatening the capsizing of the vehicle. Water baffles within 24 the water tanks divide the water tanks into small "cells" in communication with each other and prevent surging while 26 permitting the water to be effectively withdrawn from the water 27 tank. --28 The baffle in accord with t:he invention is formed of a 29 plurality of parallel longitudinal. plate members located in the water tank which are transversely intersected by a plurality of 31 transverse plate members. The longitudinal and transverse plate 32 members each include slots intersecting a longitudinal edge of 33 the plate member whereby the slots of the plate members may be 34 aligned and intermeshed. The two types of plate members are of a substantially similar height and the slots thereof extend 1 approximately half way across the transverse dimension of the 2 plate members. Upon assembly of the respective plate members, 3 the longitudinal edges thereof will be disposed adjacent each 4 other, and the fact that approximately one-half of each plate member is received within the slot of the other plate member 6 produces a mechanical connection between plate members resisting 7 relative movement therebetween.
8 Each plate member is provided with reinforcement insert 9 receiving openings located adjacent an edge of the plate member remote from the slot formed in the associated plate member, and 11 in alignment with such slot. This opening receives a 12 reinforcing insert, preferably formed of polymeric material, 13 having a base located within the opening, and four cantilevered 14 fingers which are slotted defining a pair of slots perpendicular to each other such that one slot defined by the fingers 16 straddles the associated plate member, and the other slot is in 17 alignment with the associated plate member slot.
18 Each plate member supports a reinforcing insert so that 19 upon the longitudinal and transverse plate members being transversely disposed to each other and their slots aligned, the 21 plate members may be pushed together to mesh the slots, and 22 continued relative movement of the plate members in the 23 direction of their slots causes the leading edges of the plate 24 members to be received within the slot defined between the insert fingers in alignment with the associated plate member 26 slot. In this manner, the longitudinal and transverse plate 27 members are mechanically interlocked together adjacent their 28 longitudinal edges by the insert fingers providing mechanical 29 support of the plate member edges preventing distortion and deforming during water surging.
31 The slots in the plate members mechanically support the 32 central regions of the plate members while the reinforcing 33 inserts support the edge regions of the plate members, and in 34 the practice of the invention, little, if any, welding or adhesion of the plate members to each other is required. To ' CA 02263632 1999-07-08 1 disassemble the plate members, il:. is only necessary to withdraw 2 the plate members from each other which releases the plate 3 members from the reinforcing insert of the other plate member 4 and the repair of a baffle system in accord with the invention may be easily accomplished.
6 The aforementioned advant<~ges of the invention will be 7 appreciated from the following description and accompanying g drawings wherein:

27 With reference to FIG. 1,, a typical water tank or 28 receptacle of simplified rectangular form as might be used on a 29 firefighting vehicle, or the like, is generally illustrated at 10. The tank 10 includes longitudinal walls 12, end walls 14 31 and a bottom wall 16. The tank would also include an upper wall 32 which is not shown for purpose of ;illustration. The tank may be 33 formed of polymeric material such as polypropylene or 34 polyethylene. Usually, water tanks located within fire truck vehicles will be specially configured to the available space, 1 but for purpose of illustration, a simple rectangular tank is 2 shown and the inventive concepts may be practiced with any 3 configuration of water tank.
4 The baffle used within the tank 10 to control water surging is generally indicated at 18, FIG. 1. The baffle consists of a 6 plurality of longitudinal plate members 20 and transverse plate 7 members 22. The plate members 20 and 22 are preferably formed 8 of a polymeric material such as polypropylene or polyethylene, 9 and the plate members are preferably flat and longitudinal plate member 20 includes side 24 and the opposite side 26. The plate 11 member ends 28 would engage the tank end walls 14, and the plate 12 member 20 includes an upper edge 30 and a lower edge 32. A
13 plurality of linear slots 34 are formed in plate member 20 14 intersecting sides 24 and 26, and as will be appreciated from FIGS. 3 and 4, the slots 34 are spaced along the length of the 16 plate member 20, intersect the lower edge 32, and terminate in 17 the plate member central region. Preferably, the length of the 18 slots 34 is approximately one-half the distance between edges 30 19 and 32.
A plurality of rectangular insert receiving openings 36 are 21 defined in the plate member 20 adjacent the upper edge 30 and in 22 alignment with a slot 34, and notch 38 is defined in the plate 23 member 20 adjacent the lower edge 32 and in alignment with each 24 slot 34 for receiving a reinforcing insert, as later described.
A plurality of surge holes 40 are defined in the plate member 20 26 intersecting sides 24 and 26 permitting restricted lateral 27 movement of water through the holes, but the holes are not of 28 sufficient dimension as to permit excessive water flow 29 therethrough as to produce surging.
The transverse plate members 22 are similar to the 31 longitudinal plate members 20 except that the dimension will be 32 different with respect to length. The transverse plate members 33 22 include flat sides 42 and 44. The ends 46 will engage the 34 tank walls 12, and the plate members 22 each include an upper edge 48 and a lower edge 50.
1 Transverse slots 52 are defined in plate members 22 2 intersecting the upper edge 48, and reinforcement insert 3 receiving rectangular openings 54 are deffined adjacent the lower 4 edge 50 in alignment with the slots 52, FIG. 4. Notches 56 are formed in the plate member 22 in the upper edge 48 in alignment 6 with the slots 52 wherein the notches 56 constitute an extension 7 of the slots 52 and receive the inserts of plate member 20.
8 Surge holes 58 are defined in the plate member 22 intersecting 9 the sides 42 and 44.
Preferably, the reinforcing inserts 60 which are located 11 within the plate member openings 36 and 54 are identical and are 12 formed from the same polymeric material as the plate members.
13 The inserts 60, best shown in FIGS. 2 and 5 - 7, include a 14 cylindrical base 62 which has a diameter only slightly less than the width of the insert openings 36 and 54. Each insert 60 16 includes four fingers generally indicated at 64 which extend 17 from the base 62 in a cantilevered manner and the fingers 64 18 include fingers 66, 68, 70 and 72, the transverse cross section 19 of each finger being of a quadrant type form, FIG. 7, wherein flat right angular shoulders 74 are defined upon each finger.
21 The spacing between opposed finger shoulders is such as to 22 define a pair of perpendicularly disposed slots 76 and 78.
23 To assemble the baffle 18 first requires that the 24 reinforcing inserts 60 be located within the openings 36 and 54 defined in the longitudinal plate member 20 and the transverse 26 plate member 22, respectively. Insertion of the inserts into 27 their openings consists of spreading the fingers 66 - 72 such 28 that the fingers will be slightly deformed from their usual 29 alignment with the length of the associated insert base 62 and can be inserted into their plane member opening far enough so 31 that the insert base 62 is fully received within the opening so 32 that the insert will assume the orientation shown in FIGS. 5 -33 7. For instance, with reference to FIGS. 6 and 7, the finger 68 34 is temporarily deformed away from the finger 70 and the finger 66 is deformed away from the finger 72 which widens the slot 76.
1 Thereupon, the lower end of the fingers 70 and 72 may be 2 inserted through the insert opening 36 with the fingers 3 extending toward the closest slot 34 and the insert pushed 4 downwardly, FIG. 6, upon longitudinal plate member 20 until the insert base 62 is completely located within the insert opening 6 36, as shown in FIG. 6. Once the base 62 is fully located 7 within opening 36, the entire insert will align with the plane 8 of the plate member 20 and the width of slot 76 will return to 9 normal, and at such time, the shoulders 74 on the fingers in opposed relationship to the plate member 20 will frictionally 11 grip the plate member sides 24 and 26.
12 The inserts 60 are initially located within the insert 13 receiving openings 36 and 54 of both plate members with the 14 fingers extending toward the central region of the associated plate member and the slots 78 will align with the slots 34 and 16 52 formed in the associated plate member. To assemble the 17 longitudinal plate members 20 and the transverse plate members 18 22, the plate members are aligned to each other as shown in FIG.
19 4. The length of the transverse plate member 22 is perpendicularly related to the length of the plate member 20 21 whereby the slots 34 and 52 will be aligned and the plate 22 members can be translated toward each other in the direction of 23 the slots 34 and 52. Initially, the slots 34 and 52 will 24 intermesh or overlap each other, and because the slots 34 and 52 extend approximately one-half of the height of the plate 26 members, and because the plate members are of substantially 27 equal width, the plate member 22 will be received within the 28 slot 78 of the aligned insert 60 on plate member 20, and 29 simultaneously, the insert 60 mounted upon the lower plate member 22 and the insert 60 on the transverse plate member 22 31 will enter the insert slot 78. The notches 38 and 56 provide 32 clearance for the insert base 62 as apparent in FIGS. 5 and 6.
33 In this manner, the central regions of the plate members 20 and 34 22 will be in a mechanical locked relationship due to the receiving of the plate member 20 in the slot 52 of the 1 transverse plate member 22, .and the location of the transverse 2 plate member 22 within the slot 34 of the plate member 20.
3 Further, the edge regions of the transverse plate member 22 4 adjacent edges 48 and 50 will be reinforced against deformation by the upper and lower inserts 60.
6 If desired, the plate members 20 and 22 can be welded 7 together by polymeric welding or solvents at limited areas or 8 spots, and the close reception of the insert bases 62 within the 9 openings 36 and 54 firmly supports and positions the other plate member by engagement with the fingers 64. It will be 11 appreciated that the diameter of the inserts 60, and dimension 12 of the fingers 64, is substantial enough to form sufficient 13 strength to resist surging forces imposed upon the baffle 14 components. If the vehicle containing the tank is involved in an accident, any welding of the baffle components that was 16 previously done can be cut out, and the baffle quickly repaired.
17 It is appreciated that various modifications to the 18 inventive concepts may be apparent to those skilled in the art 19 without departing from the spirit and scope of the invention.

4 The baffle used within the tank 10 to control water surging is generally indicated at 18, FIG. 1. The baffle consists of a 6 plurality of longitudinal plate members 20 and transverse plate 7 members 22. The plate members 20 and 22 are preferably formed 8 of a polymeric material such as polypropylene or polyethylene, 9 and the plate members are preferably flat and longitudinal plate member 20 includes side 24 and the opposite side 26. The plate 11 member ends 28 would engage the tank end walls 14, and the plate 12 member 20 includes an upper edge 30 and a lower edge 32. A
13 plurality of linear slots 34 are formed in plate member 20 14 intersecting sides 24 and 26, and as will be appreciated from FIGS. 3 and 4, the slots 34 are spaced along the length of the 16 plate member 20, intersect the lower edge 32, and terminate in 17 the plate member central region. Preferably, the length of the 18 slots 34 is approximately one-half the distance between edges 30 19 and 32.
A plurality of rectangular insert receiving openings 36 are 21 defined in the plate member 20 adjacent the upper edge 30 and in 22 alignment with a slot 34, and notch 38 is defined in the plate 23 member 20 adjacent the lower edge 32 and in alignment with each 24 slot 34 for receiving a reinforcing insert, as later described.
A plurality of surge holes 40 are defined in the plate member 20 26 intersecting sides 24 and 26 permitting restricted lateral 27 movement of water through the holes, but the holes are not of 28 sufficient dimension as to permit excessive water flow 29 therethrough as to produce surging.
The transverse plate members 22 are similar to the 31 longitudinal plate members 20 except that the dimension will be 32 different with respect to length. The transverse plate members 33 22 include flat sides 42 and 44. The ends 46 will engage the 34 tank walls 12, and the plate members 22 each include an upper edge 48 and a lower edge 50.
1 Transverse slots 52 are defined in plate members 22 2 intersecting the upper edge 48, and reinforcement insert 3 receiving rectangular openings 54 are deffined adjacent the lower 4 edge 50 in alignment with the slots 52, FIG. 4. Notches 56 are formed in the plate member 22 in the upper edge 48 in alignment 6 with the slots 52 wherein the notches 56 constitute an extension 7 of the slots 52 and receive the inserts of plate member 20.
8 Surge holes 58 are defined in the plate member 22 intersecting 9 the sides 42 and 44.
Preferably, the reinforcing inserts 60 which are located 11 within the plate member openings 36 and 54 are identical and are 12 formed from the same polymeric material as the plate members.
13 The inserts 60, best shown in FIGS. 2 and 5 - 7, include a 14 cylindrical base 62 which has a diameter only slightly less than the width of the insert openings 36 and 54. Each insert 60 16 includes four fingers generally indicated at 64 which extend 17 from the base 62 in a cantilevered manner and the fingers 64 18 include fingers 66, 68, 70 and 72, the transverse cross section 19 of each finger being of a quadrant type form, FIG. 7, wherein flat right angular shoulders 74 are defined upon each finger.
21 The spacing between opposed finger shoulders is such as to 22 define a pair of perpendicularly disposed slots 76 and 78.
23 To assemble the baffle 18 first requires that the 24 reinforcing inserts 60 be located within the openings 36 and 54 defined in the longitudinal plate member 20 and the transverse 26 plate member 22, respectively. Insertion of the inserts into 27 their openings consists of spreading the fingers 66 - 72 such 28 that the fingers will be slightly deformed from their usual 29 alignment with the length of the associated insert base 62 and can be inserted into their plane member opening far enough so 31 that the insert base 62 is fully received within the opening so 32 that the insert will assume the orientation shown in FIGS. 5 -33 7.

To assemble the 17 longitudinal plate members 20 and the transverse plate members 18 22, the plate members are aligned to each other as shown in FIG.
19 4. The length of the transverse plate member 22 is perpendicularly related to the length of the plate member 20 21 whereby the slots 34 and 52 will be aligned and the plate 22 members can be translated toward each other in the direction of 23 the slots 34 and 52. Initially, the slots 34 and 52 will 24 intermesh or overlap each other, and because the slots 34 and 52 extend approximately one-half of the height of the plate 26 members, and because the plate members are of substantially 27 equal width, the plate member 22 will be received within the 28 slot 78 of the aligned insert 60 on plate member 20, and 29 simultaneously, the insert 60 mounted upon the lower plate member 22 and the insert 60 on the transverse plate member 22 31 will enter the insert slot 78. The notches 38 and 56 provide 32 clearance for the insert base 62 as apparent in FIGS. 5 and 6.
33 In this manner, the central regions of the plate members 20 and 34 22 will be in a mechanical locked relationship due to the receiving of the plate member 20 in the slot 52 of the 1 transverse plate member 22, .and the location of the transverse 2 plate member 22 within the slot 34 of the plate member 20.
3 Further, the edge regions of the transverse plate member 22 4 adjacent edges 48 and 50 will be reinforced against deformation by the upper and lower inserts 60.
6 If desired, the plate members 20 and 22 can be welded 7 together by polymeric welding or solvents at limited areas or 8 spots, and the close reception of the insert bases 62 within the 9 openings 36 and 54 firmly supports and positions the other plate member by engagement with the fingers 64. It will be 11 appreciated that the diameter of the inserts 60, and dimension 12 of the fingers 64, is substantial enough to form sufficient 13 strength to resist surging forces imposed upon the baffle 14 components. If the vehicle containing the tank is involved in an accident, any welding of the baffle components that was 16 previously done can be cut out, and the baffle quickly repaired.
17 It is appreciated that various modifications to the 18 inventive concepts may be apparent to those skilled in the art 19 without departing from the spirit and scope of the invention.
