TW201932693A - Handheld scraper comprising a handle, a scraping blade, and an elastic connector for connection of the handle and the scraping blade - Google Patents

Abstract

The present invention relates to an elastic connector and a handheld scraper including the elastic connector, comprising: a handle, a scraping blade, and an elastic connector for connection of the handle and the scraping blade, wherein the elastic curved section is capable of generating elastic deformation upon receiving a force acting thereon in order to conduct pressure out and to resume the original form upon varnishing of the force to thereby achieve an effect of pressure releasing. With such a structure, when the handheld scraper is used to carry out repairing of a wall surface, the elastic connector may properly release the counteracting force induced by an operation of applying a force to the wall surface and thus reduce the chance of hurting hand limbs thereby making a scarper operation more comfortable and more efficient.

Description

Elastic connecting member and hand-held scraper having the elastic connecting member

The invention relates to a hand-held scraper suitable for wall surface finishing or for scraping foreign objects on glass, walls and floor surfaces, in particular to have an elastic connecting member capable of releasing a reaction force generated by applying force to the wall surface. Handheld scraper.

A conventional hand-held scraper 100 as shown in FIG. 1 is mainly composed of a grip 11 and a scraper 12 attached to the grip. During use, the scraper is applied to the wall surface. The reaction force will be transmitted back to the hand, and if it is subjected to a sustained reaction for a long time, it will easily cause damage to the wrist or even the arm.

When using the hand-held scraper for wall finishing work, the hand limbs may be damaged by the wall reaction force during the process. At present, no solution or improvement scheme for the design of the scraper is provided.

In view of this, the main object of the present invention is to provide a hand-held blade which can effectively reduce the reaction force of the wall surface conduction back during use, and achieve the function of reducing the injury of the hand limb.

According to the above object, the present invention provides an innovative hand-held blade structure, which mainly comprises: a grip, a scraper and an elastic connecting member for connecting the grip and the scraper; wherein the elasticity The connecting member comprises: a first engaging portion for contacting the grip; a second engaging portion for contacting the scraping plate; and a resilient curved portion formed at the first engaging portion and the The second joint portion, wherein the elastic curved portion is capable of elastic deformation when subjected to a force, is used to guide the pressure out, and returns to the original state after the force is lost, thereby achieving the effect of pressure release.

With this configuration, unlike the conventional hand-held scraper, the hand-held scraper of the present invention uses an elastic connecting member to connect the design of the grip and the scraper, and when the wall surface is repaired by using the scraper, the elastic connecting member can be appropriately The ground releases the reaction force generated by the force applied to the wall, reduces the chance of injury to the hand limb, and makes the blade work more comfortable and efficient.

In the present invention, the grip portion and the first joint portion of the elastic connecting member are respectively provided with an engaging groove and a block which can be fitted to each other.

In the present invention, the second engaging portion of the elastic connecting member is provided with a fitting groove for fitting the scraping plate.

In the present invention, the squeegee is adhesively bonded to the second joint portion of the elastic connecting member.

In the present invention, the elastic connecting member is a metal sheet or a plastic sheet which is elastic.

In the present invention, the elastic curved portion has a U shape.

In the present invention, the grip includes a grip portion and a receiving portion for connecting with the elastic connecting member.

The detailed features and advantages of the present invention are set forth in the Detailed Description of the Detailed Description of the <RTIgt; </ RTI> <RTIgt; </ RTI> </ RTI> </ RTI> <RTIgt; The objects and advantages associated with the present invention can be readily understood by those skilled in the art.

Referring first to FIG. 2, FIG. 3 and FIG. 4, the hand-held scraper 200 of the present invention mainly comprises a grip 21, a scraper 22, and an elastic connecting member for connecting the grip 21 and the scraper 22. twenty three.

The grip 21 includes a grip portion 211 suitable for the user to hold, and a receiving portion 212 extending from the grip portion for connecting with the elastic connecting member 23. In practice, the grip 21 can be designed or ergonomically comfortable to grip.

The squeegee 22 is a piece of sheet that is indirectly connected to the grip 21 through the elastic connecting member 23, and can be used for refurbishing or scraping surface foreign matter against the wall surface.

The elastic connecting member 23 can be formed by using a resilient metal piece or a plastic piece. As shown, the elastic connecting member 23 includes a first engaging portion 231 for contacting the grip 21 for use. A second engaging portion 232 that is in contact with the squeegee 22 and an elastic curved portion 233 formed between the first engaging portion 231 and the second engaging portion 232.

The elastic connecting member 23 may be respectively connected to the grip 21 and the scraper 22 by a detachable or fixed inseparable knot, and includes a fitting, an adhesive, a locking and the like.

In the embodiment of the present invention, the grip 21 and the elastic connecting member 23 are connected to each other in a detachable manner, that is, the first joint of the grip 21 and the elastic connecting member 23 Each of the 231 is provided with an engaging groove 213 and a block 234 which can be coupled to each other, and the assembling or disassembling action can be quickly completed. In addition, the squeegee 22 and the elastic connecting member 23 are in an inseparable manner, wherein the second engaging portion 232 of the elastic connecting member 23 is provided with a fitting groove 235 for fitting the squeegee 22, It is then further fixed by pasting or locking.

With this configuration, the hand-held doctor blade 200 of the present invention adds a design of the elastic connecting member 23, and the grip 21 is compared with the conventional manner in which the conventional hand-held blade 100 directly connects and fixes the blade 12 to the grip 11. The squeegee 22 is connected to both ends of the elastic connecting member 23, respectively.

As shown in FIG. 5 and FIG. 6 , when the wall surface 30 is repaired by using the hand-held scraper 200 of the present invention, the elastic connecting member 23 can elastically deform the reaction force of the wall surface 30, and further, when When the squeegee 22 is removed from the wall surface 30, the elastic connecting member 23 will also return to the original state at the same time, and during the elastic recovery process, the pressure of the squeegee 22 to be pressed down will be absorbed, and the probability of the hand limb being damaged is reduced.

The elastic connecting member 23 disclosed in the present invention includes, but is not limited to, a hand-held scraper 200. In practice, the elastic connecting member 23 can also be applied to a paint brush, a toilet brush, and other hand-held tools for different purposes. That is, for a hand-held tool of different functional types, the first engaging portion 231 and the second engaging portion 232 of the elastic connecting member 23 can be respectively connected to the grip and the brush head.

The above are only the preferred embodiments of the present invention, and should not be used to limit the scope of the present invention, and all changes and modifications made in accordance with the scope of the present invention should fall within the scope of the present invention. .
