Abstract

The utility model relates to a labor protection appliance, particularly to a labor protection appliance for protecting knee joints. The utility model is composed of a main body, elastic bands and nylon hasps, wherein the main body is composed of a containment vessel made of rigid plastics and a spring cushion adhered in the containment vessel; the elastic bands and the nylon hasps are used for binding the kneecap to the knee joint. The containment vessel which looks like an unclosed clamshell is divided into an upper section and a lower section which are connected by a folded strip. When in use, the upper section and the lower section of the containment vessel can change in different angles by altering the kneeling postures of the knee joint. The containment vessel protects the users by preventing hard objects on the ground from penetrating the kneecap to damage human bodies. The spring cushion adhered inside is used for ensuring the indirect contact between the knee and the rigid plastic containment vessel in order that any part of the knee can not obtain over great pressure.

Description

Labour protection kneecap

The utility model relates to a kind of appliances for labor protection, the kneed appliances for labor protection of particularly a kind of protection.

Be engaged in the industrial production, adopt kneeling position to operate in institute unavoidably in operation as work posts such as shipbuilding, construction and installation and electrogas weldings, this long-time kneeling position, knee joint contacts with ground, metal or other hard thing for a long time, knee joint very easily causes the injury of aching, strain, galling and damaging etc. injury of human, thereby reduces operating efficiency.When practical operation, generally all take as filling up interim measures such as some cottons, hardboard, existingly generally all can not use as the labour protection article as warming use as the wool felt knee-pad.

The purpose of this utility model is to provide a kind of knee-pad that has the hard containment vessel and be filled with cushion pad, makes the workman when kneeling position is worked, and knee was both comfortable, safety, can keep high operating efficiency.

The utility model is achieved in that of the present utility model being characterised in that by rigid plastics containment vessel and the elastic buffering pad that is bonded in containment vessel inside form its main body, and with elastic cord and the velcro knee-pad tied up in the knee joint upper and lower part.The clam shell that containment vessel is seemingly opened is divided into upper and lower two, and is middle continuous by tortuous muscle, and the kneeling position with the joint during use changes, and upper and lower two parts containment vessel can change the angle that is different.This hard thing in containment vessel principal security ground can not penetrate knee-pad and damage human body, protection operator's safety.Cushion pad that inside is stained with guarantees that between knee and hard containment vessel be not directly to contact, and can not make certain part of knee that overweight pressure burden is arranged.

Advantage of the present utility model is:

1. because the containment vessel of hard is arranged, guarantee that the hard thing in ground can not penetrate knee-pad and damage human body, protection operator's safety;

2. owing to being to link to each other between two containment vessels,, containment vessel changes so can being close to the joint with the difference of kneeling position by tortuous muscle;

3. because inside is stained with cushion pad, body wt can be evenly distributed on the knee joint, make certain part of human body can not feel overweight pressure burden.

Accompanying drawing is described in conjunction with the embodiments

The utility model by rigid plastics containment vessel 1 and 2 and the elastic buffering pad 4-6 that is bonded in containment vessel 1 and 2 inside form its main body, and with elastic cord 7 and the velcro 8 (Fig. 1) knee-pad tied up in the knee joint upper and lower part.The clam shell that containment vessel is seemingly opened is divided into slice 1 and following sheet 2, middlely link to each other (A of Fig. 2) by tortuous muscle 3, during use with the kneeling position variation in joint, containment vessel last slice 1 can change the angle (B of Fig. 2) that is different with following sheet 2.This hard thing in containment vessel principal security ground can not penetrate knee-pad and damage human body, protection operator's safety.

The part 9 that containment vessel when kneeling position is with ground directly contacts on nearly tortuous muscle 3 both sides is plane (dotted portion of Fig. 2 A); making containment vessel is that face contacts with ground or hard thing; remaining edge is arcuation; make containment vessel can be close to knee, containment vessel last slice 1 and the dual-side of following sheet 2 slotted hole 11 that passes elastic cord 7 is all respectively arranged.Cushion pad 4 and 5 is divided into two-layer; outer a is to be to be made by middle flexible foam combination by high resilience foam, internal layer b; cushion pad 4 is bonded under the containment vessel in the sheet 2; cushion pad 5 is bonded in the containment vessel last slice 1; middle cushion pad 6 is main parts of the force, is made with the protection knee joint by elastomeric rubber.Cushion pad 4 bottoms are crooked in the mating protection shell, are provided with several breach 4.
