DE20316093U1 - Paint brush, comprising bristle head adjustable in relation to handle and to be fixed in this position with clamping element - Google Patents

Abstract

The lower end of the bristle head (3) is fitted with a ball joint or a T-shaped insertion element (6) with a polygonal mantle for being joined to a socket part (5), provided at the upper end of the handle stick (2). When the bristle head (3) is moved into the required position in relation to the stick (2) it is secured with a clamping element (10) in the shape of a flexible bow (11) with a hook (12) at its outer end engaging with a projection (13) located at the brush.

Description

Cranked brush (= radiator brush) there is on the market.

There are fixed brushes and those that are cranked by turning, swiveling, kinking can.

The variable brushes, both cranked as can also be used in a straight line, have different embodiments about the bend to reach.

One embodiment is that the brush head and handle on oblique area in the longitudinal axis are rotatably mounted on a screw with spring. In one Position, the brush head is straight to the handle while it is in the other position to the stem axis in the given by the inclined surfaces Dimensions is skewed.

Another embodiment has one in style angelängten t-shaped Pen . This pen holds the brush head together. The weird ones contact surfaces of the brush head and handle specify the offset positions.

In both embodiments is in the respective End position of the brush head straight or bent to Brush handle.

All of these designs have a weak point. The adjacent slopes are rotatable and locked against each other. The brushes are however not sufficiently secured in the respective end positions. This allows it during unintentionally cranking or loosening the joint.

Object of the invention

The object of the invention is a To create brushes of

• - yourself Adjust both straight and bent to the handle axis leaves.
• - yourself bend easily with only one hand or just put it.
• - yourself secured in the respective end position against changes in angle.
• - light can be cleaned.
• - cheap can be manufactured.
• - on- or multicolored from one or more material components can be.
• - in more than two crank positions is adjustable.

Solution of the task

The bendable brush 1 consists of brush head 2 and brush handle 3 , There is a joint at the connection point 4 educated.

This joint 4 consists of a brush handle 3 attached camp 5 and to the camp 5 matching T-pin 6 , This arrangement can be exchanged. The warehouse 5 and the T-pin 6 have round contact surfaces 7 ,

However, the brush head should have several different bends 8th to the brush handle 3 be ascertainable, so the contact surfaces 7 not circularly round but polygonal 9 educated.

This allows brush head 2 and brush handle 3 in different, through the contact surfaces 7 given angles 8th join in more than two positions.

The locking of the joint 4 is achieved by a deformable clamping device attached to the brush handle 10 ,

This clamping device 10 consists of the clamp 11 and your hook attached to the clamp 12 , The clamp bracket 11 is on one long side 14 of the brush handle 3 attached.

The hook 12 engages when locking the brush head 2 with brush handle 3 into a suitably trained nose 13 ,

That nose 13 is on the opposite long side 15 to the long side 14 , on which the clamping bracket 11 attached, attached.

The locking of the joint 4 is achieved in that after the camp 5 and the T-pin 6 are joined together via the joint 4 the clamp 11 is panned.

The clamp bracket 11 deformed so far that the hook 12 in the nose 13 engages under tension.

The clamping bracket, which is under tension due to the deformation 12 causes brush head 2 and brush handle 3 cannot twist against each other. Do you want brush head 2 and brush handle 3 against each other in the joint 4 twist, so the hook 12 from the nose 13 be solved.

The hook 12 is from the nose 13 solved by looking at the flag 16 that on the hook 12 is appropriate. The clamp will then lose 11 its tension and in the joint 4 can camp 5 and T-pin 6 be moved against each other. So that the joint 4 does not open fully and brush head 2 and the brush handle fall apart, the hook gets 12 a counter hook 17 ,

This counter hook 17 hooks on the brush handle 3 after releasing the hook 12 automatically.

You have the bent part of the brush 1 in the joint 4 the joint is adjusted 4 clamped again by looking at the fixed point or fixed edge from the brush head towards the end of the brush handle against the hook 11 with his flag 16 suppressed. This will make the clamp 11 deformed and under tension, the hook 12 can on the nose 13 click into place, holding the joint 4 fixed again.

Another form of training is that the T-pin 6 no crossbar at its outer end 18 but a ball 19 having. The warehouse 5 will become yours as a hollow hemisphere 20 educated.

This turns the joint 4 a ball joint 21 ,

With the ball joint 21 can the brush 1 can no longer be bent in one plane, but can be moved freely in space around at least 4 axes.

The brush user can use it Adjust the brush individually to your needs at any time.

Another advantage of this design is that the brush consists of only two parts brush head 2 and brush handle 3 consists. The parts of the joint are firmly attached to the individual parts and cannot be lost.

Will the clamp 11 over the counter hook 17 open out, so can brush head 2 and brush handle can be cleaned easily and thoroughly for further use. The disadvantage of a mechanism with one or more loose or fixed small parts that can be lost and that are difficult to clean is avoided.
