This invention relates to gutter cleaning devices, and more particularly to a water-assisted blower and vacuum attachment for use in gutter cleaning.
Numerous different devices are known for cleaning rain gutters and gutter systems. These include vacuum and pressurized air-type devices typified by U.S. Pat. Nos. 3,971,098; 4,402,106; 5,586,360; and 6,519,809, and water-pressure and water-delivery-type devices typified by U.S. Pat. Nos. 4,363,335 and 5,037,028. There are also mechanical gutter cleaning devices such as typified by U.S. Pat. Nos. 4,319,851; 4,718,613 and 5,855,402. The vacuum-type devices have no provision for washing down the gutter troughs after the leaves and other debris have been removed, the latter done by such methods as scraping, blowing or vacuuming. That is, the vacuum-type devices have no capability of using a water jet to blast loose the accumulated leaf debris in a gutter. On the other hand, the water-type devices have no provision for assuring substantial removal of the debris, whether by blowing or vacuuming of it, once a pressurized water jet is used to dislodge the same.
There has been a need for a gutter cleaning apparatus that provides sufficient impact force to dislodge and loosen encrusted leaves and other debris found in a roof gutter, while additionally being able to remove such dislodged debris.
The present invention in one aspect provides a curved end elbow-like attachment member operable to connect to an elongated blower and vacuum air conduit to reach elevated gutter areas, coupled with a pressurized water nozzle mounted to the curved end attachment member. The water jet provides sufficient water force to dislodge encrusted leaves and other debris from a gutter, while the blowing (or alternatively the vacuum) capability of the curved end attachment member permits ready blowing (or vacuum) removal of that now-dislodged leaf debris.
The curved end attachment member can take the form of a plastic extruded or injection molded curved member, capable of attachment at one end to an existing elongated blower or vacuum air conduit, while at the other end having a free operating end, usable for blowing or vacuuming of forced air. Further, the pressurized water jet can take the form of a water conduit connected to the elongated air conduit, as well as to the curved end attachment member. More specifically, the water supply hose can be fastened to both the elongated air conduit as well as the curved end attachment member. That hose can either be mounted internally or externally of the curved end attachment member. Additionally, the pressurized water nozzle for the water supply hose can be mounted at the terminal end of the curved end attachment member, somewhat removed from that terminal end, or even more substantially removed from that terminal end, such that the pressurized water jet can exit through the same conduit as the blowing (or vacuum) air, or can even be mixed with the blowing (or vacuum) air for delivery to the encrusted gutter debris. In the latter case, the blowing air helps to increase the velocity, and hence the blasting and cleaning effect, of the water.
In an alternate arrangement, the elongated air conduit and the curved end attachment member can be separately fitted with, or integrally formed with, hose grip members, for detachably retaining the hose along the exterior of such air conduit and curved end attachment member.

Further, a pressurized water hose supply, generally denoted by reference numeral 40, is mounted to the rear side of the elongated air conduit 26, and along the back and across the top of the curved end member 20. More specifically, the water hose assembly 40 includes a water hose segment 42 mounted to the rear of the air conduit 26 and of curved end member 20 by way of retainer means 44, shown in the drawings as band clamps, and terminating in a water nozzle 46. The other end of water hose segment 42 includes a positive shut off valve member 48 and a terminal female connector end 50 operable to connect to the male end 52 of the suitable pressurized water supply line 54. It will be noted that the connectors 44 will preferably be either metal or plastic band clamps, but could also be in the form of plastic or metal wire tie members (not shown). Further, the shut-off valve can take, for example, the form of a rotary type sill cock valve, or a pinch clamp or squeeze valve. The water hose 42 can be formed as a section of common garden hose, or as a section of clear flexible tubing material, or even as a harder, extruded or injection-molded plastic tubular segment.
In operation, the combination water jet and blowing apparatus assembly 36 is manipulated so that the free operating end 34 of curved end attachment member 20 is placed within a gutter system needing cleaned (not shown). In one aspect, the blowing (or vacuum air) source, via hose 38, is initiated, whereby either blowing or vacuum air operates through the free end 34 of curved member 20 to remove dislodged leaves and other debris residing in the gutter. Thereafter, once the forced air being supplied by hose 38 is discontinued, the hose shut off member 48 can be activated, whereby pressurized water supplied by line 54 moves through the water hose assembly 40, and exits in a blasting-type water jet stream exiting from the water nozzle 46. That water jet operates to dislodge any leaves, debris, shingle fines, and other undesirable material that has accumulated within the gutter. Whereupon, if desired, the pressurized water via line 54 can be discontinued (by turning off the hose shut off 48), and the forced air reinitiated through supply line 38, whereby the remaining debris in the gutter can be removed by forced air operating through free end 34. It will be understood that either water pressure or forced air can be initiated first, and then the other, separately, or in combination, as desired, and repeated as much as needed.
It will be understood that, instead of having the tip 56 of water nozzle 46 terminate approximately adjacent the outer terminal ends of the rib 42 of curved member 20 (as seen in
In another aspect of the invention, there is depicted in
In this embodiment, the curved end attachment member, generally denoted by reference numeral 60, is slightly modified in that, while otherwise the same as curved end attachment member 20 of the first embodiment, it has a specially-configured, integrally-formed water jet nozzle 62. More specifically, modified water jet nozzle 62 includes an exteriorly-extending portion 64 having a female connector 66 operable to accept a male connector 68 of the water hose segment 42. Additionally, there is an internally-extending, angularly-canted water jet nozzle portion 70 having a tip end 72 that points upwardly towards the upper curved interior of curved end attachment member 60.
In the operation of modified assembly 58, instead of having the water jet presented at an exterior location relative to terminal end 34, the water jet emerges from the interior of modified curved attachment member 60, via the interiorly-positioned water nozzle 70, and thus exits through the free operating end 34 (when assembly 58 is being operated in the water jet operation mode). Otherwise, when the shut off valve 48 has been put in the off position, such that water no longer exits through internally positioned nozzle tip end 72, any forced air supplied via hose 38 operates to blow away (or vacuum up) gutter leaf debris via free operating end 34, just as done with the first embodiment (of
It will be seen that one advantage of assembly 58 of this second embodiment, as shown in
Alternatively, it will be understood that, instead of having the water jet nozzle formed as an integral unit with the modified curved end attachment member 60 (per

Again, during operation, when the water jet is turned on, via hose shut off member 48, the stream of pressurized water exiting water nozzle 82 is presented from the internal end of free end 34, for blasting gutter debris. Then, when that pressurized water flow has ceased, by turning off the hose shut off 48, forced air (blowing or vacuum) can be sent through air conduit 26 to exit free operating end 34, so as to blow away (or vacuum up) the gutter leaf debris. Again, if desired by the end user, both the forced air and pressurized water streams can be operated at the same time.
If preferred, a sealing grommet member 88 (see
