WALL SCRAPER
A scraper, such as a wall scraper using a standard replaceable blade, is provided with an adjustable scraper head for changing the attack angle of the blade to suit the user and/or the job. Embodiments include a scraper having an elongated handle and a scraper head for fixedly holding a blade, the scraper head being pivotably mounted to an end of the handle for positioning the scraper head at a selected angle to the handle. A lock, engageable with the handle and the scraper head, fixes the scraper head at the selected angle. The lock has a knob for gripping the scraper, and the handle has a rear grip, thus allowing the user greater control of the scraper.
The present invention claims priority of provisional patent application No. 61/006,754 filed Jan. 30, 2008, the contents of which are incorporated herein in their entirety
TECHNICAL FIELDThe present disclosure relates to a scraper. The present disclosure has particular applicability to wall scrapers with replaceable blades.
BACKGROUNDWall scrapers, also called wall strippers, are used to remove paint, wallpaper, etc. from walls. They are typically used with two hands. All such scrapers provide a grip at the rear of the handle, and some have a knob on the front of the housing to provide an additional grip. A typical conventional design, as shown in
An advantage of the present disclosure is a scraper with an adjustable scraper head whose angle with respect to its handle can be changed according to the user and/or to the job at hand.
According to the present disclosure, the foregoing and other advantages are achieved in part by a scraper comprising an elongated handle; a scraper head for fixedly holding a blade, the scraper head being pivotably mounted to a first end of the handle for positioning the scraper head at a selected angle to the handle; and a lock engageable with the handle and the scraper head for fixing the scraper head at the selected angle.
Additional advantages and other features of the present disclosure will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from the practice of the disclosure. The advantages of the disclosure may be realized and obtained as particularly pointed out in the appended claims.
As will be realized, the present disclosure is capable of other and different embodiments, and its several details are capable of modifications in various obvious respects, all without departing from the disclosure. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
Reference is made to the attached drawings, wherein elements having the same reference numeral designations represent like elements throughout, and wherein:
A scraper according to the present disclosure addresses the disadvantages of conventional wall scrapers having a head at a fixed angle to the handle. The present disclosure provides a scraper with an adjustable scraper head whose angle with respect to the handle can be changed to suit the user and/or the job. The scraper of the present disclosure also has textured grips for both the user's hands for better control, and storage space for extra blades inside its handle.
Referring now to
As shown in
As shown in
In one embodiment of the disclosed scraper, the rear grip 11a has two opposed side buttons 22 which extend through corresponding holes 11b to hold the end cap 26 in place (see
In still further embodiments, as shown in
The scraper of the present disclosure allows the blade 17 to be adjusted to any comfortable angle by unscrewing the knob 12, moving the head 15, and tightening the knob 12. The disclosed adjustable blade angle enables comfortable use of the scraper by right and left handed users. Moreover, the grip 12a of knob 12 enables increased pressure to be applied to the scraper during use, because it allows the user to use both hands. Still further, enabling the use of both hands by the user allows greater control of the tool during scraping.
The present disclosure can be practiced by employing conventional materials, methodology and equipment. Accordingly, the details of such materials, equipment and methodology are not set forth herein in detail. In the previous descriptions, numerous specific details are set forth, such as specific materials, structures, chemicals, processes, etc., in order to provide a thorough understanding of the disclosure. However, it should be recognized that the present disclosure can be practiced without resorting to the details specifically set forth. In other instances, well known processing structures have not been described in detail, in order not to unnecessarily obscure the present disclosure.
Only a few examples of the present disclosure are shown and described herein. It is to be understood that the disclosure is capable of use in various other combinations and environments and is capable of changes or modifications within the scope of the inventive concepts as expressed herein.
Claims
1. A scraper comprising:
- an elongated handle;
- a scraper head for fixedly holding a blade, the scraper head being pivotably mounted to a first end of the handle for positioning the scraper head at a selected angle to the handle; and
- a lock engageable with the handle and the scraper head for fixing the scraper head at the selected angle.
2. The scraper of claim 1, wherein the lock comprises a shaft which engages respective through-holes in the handle and the scraper head to pivotably mount the scraper head to the handle, and
- wherein the shaft further engages a fastener for fixing the scraper head at the selected angle.
3. The scraper of claim 2, wherein the lock further comprises a knob at one end of the shaft for engaging the shaft and the fastener, and for secure gripping of the scraper by a user.
4. The scraper of claim 3, wherein the shaft is threaded, and the fastener has threads for engaging the threads of the shaft, and the knob is for tightening the shaft to the fastener.
5. The scraper of claim 2, wherein the handle has a first splined detent ring, and the scraper head has a second splined detent ring for engaging the first splined detent ring, for positioning the scraper head at the selected angle when the shaft engages the through-holes in the handle and the scraper head.
6. The scraper of claim 1, wherein the blade is removable.
7. The scraper of claim 1, wherein the handle comprises a rear grip at a second end of the handle remote from the first end, for gripping of the handle by a user.
8. The scraper of claim 7, wherein the rear grip comprises a recessed portion for accommodating a thumb of the user when the user is gripping the handle.
9. The scraper of claim 7, wherein the handle is hollow, and comprises a blade storage compartment inside the rear grip.
10. The scraper of claim 9, wherein the rear grip comprises a removable end cap for accessing the blade storage compartment.
11. The scraper of claim 10, wherein the end cap comprises an opposing pair of resilient tabs having buttons which engage a pair of corresponding through-holes in the rear grip to retain the end cap on the rear grip, and to allow removal of the end cap from the rear grip when the user depresses the buttons.
12. The scraper of claim 10, wherein the end cap has threads, and the rear grip has threads for engaging the end cap threads to removably attach the end cap to the rear grip.
13. The scraper of claim 10, wherein the end cap attaches to the rear grip via a friction fit.
14. The scraper of claim 9, wherein the rear grip comprises a hinged end cap for accessing the blade storage compartment.
15. The scraper of claim 14, wherein the end cap comprises a resilient latch which engages a through-hole in the rear grip to retain the end cap on the rear grip, and to allow removal of the end cap from the rear grip when the user depresses the latch.
