Safety shoe

This invention relates to a safety shoe which is similar to the structure and function of a sport shoe comprising a conventional tennis shoe type sole receiving a steel plate therein provided at the front end with a plurality of slots, a shoe upper face attached to said sole being divided into a vamp section and two side portions, said side portions provided with two pairs of first and second pockets, a toe lining attached to the inner face of said vamp section to form a bag, a front cover disposed in said bag to protect the wearer's toes, a facing partly overlapping said side portions and provided along the inner margins with a plurality of eyelets through which a lace may pass, a pair of fixing laces being anchored on the opposite sides of said facing, a protecting cover provided on the opposite sides with two pairs of first and second legs which correspond to said first and second pockets overlaying said facing with its first and second legs respectively inserting into said first and second pockets of said side portions and fixed in position by said fixing laces and an insole coming with a front wall being positioned on said sole.

BACKGROUND OF THE INVENTION 
This invention relates to a safety shoe and in particular to the type which 
is similar to the structure and function of a sport shoe. 
A safety shoe is used to prevent the wearer's foot from being injuried when 
the wearer is engaged in a dangerous work. 
Commonly used safety shoe (7), as shown in FIG. 5, is generally of the 
leather shoe type and provided with a front cover (71) made of steel or 
other similar materials which is positioned on the vamp section of said 
shoe and glued thereon to prevent the wearer's toes from being injuried, 
and further provided with a hard sole (72) of which the edge extends to 
form a platform to prevent the wearer's foot from being pierced. However 
the connection between said front cover (71) and the vamp section of said 
sole is only by gluing, hence it is too weak to endure a violent 
collision, and since the front cover is only located on the vamp section 
of said shoe to protect the wearer's toes, the instep of the wearer's foot 
is still unprotected. Furthermore said sole is so hard that it is 
difficult for the wearer to bend his foot, hence it is not suitable for 
the wearer to climb up to a height during his work. 
Another disadvantage is that the facing (73) of said shoe (7) provided with 
a plurality of eyelets overlaps only the instep of the wearer's foot, thus 
it is impossible for the wearer to adjust the tightness and looseness of 
the joint girth of his foot. 
Still another disadvantage is that the extending platform of said sole of 
said commonly used safety shoe will make rolling objects easily roll up to 
and injure the instep of the wearer's foot. 
It is, therefore, an object of the present invention to obviate the 
above-mentioned drawbacks. 
SUMMARY OF THE INVENTION 
It is the primary object of the present invention to provide a safety shoe 
of which the structure is similar to a sport shoe. 
It is another object of the present invention to provide a safety shoe, 
wherein the sole receives a steel plate therein which is formed at the 
front end with a plurality of slots to increase the flexibility of the 
sole and to make the wearer's foot easily bent. 
It is still another object of the present invention to provide a safety 
shoe, wherein a front cover is secured to the inner face of the vamp 
section of the shoe by means of both gluing and rivetting to reinforce the 
connection therebetween 
It is a further object of the present invention to provide a safety shoe, 
wherein a protecting cover is positioned on the top of the facing of said 
shoe to provide a further protection for the instep of the wearer's foot.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to the specific embodiment of the invention selected for 
illustration in the accompanying drawings and in particular to FIGS. 3 and 
4. A safety shoe (10) comprises a tennis shoe type sole (1) consisting of 
a bottom sole (11), a steel plate (12) properly provided at the front end 
with a plurality of slots (121) to increase the flexibility of the sole 
(1) and to make the wearer's foot easily bent being connected to the top 
of said bottom sole (11) and an outer sole (13) provided around its 
periphery with a fixing wall (131) being attached to the top of said steel 
plate (12), the front end of said fixing wall (131) being provided with a 
plurality of first holes (132), and two pairs of first and second recesses 
(133) (134) being respectively formed on the opposite sides of said fixing 
wall (131). Said bottom sole (11), steel plate (12) and outer sole (13) 
can be formed integrally with known techniques to produce a complete sole 
(1). 
A shoe upper face (2) attached to the fixing wall (131) of the outer sole 
(13) of said sole (1) is divided into a vamp section (22) and two 
symnetrical side portions (23). Said vamp section (22) provided at the 
front end with a plurality of second holes (221) which correspond to said 
first holes (132), and said side portions (23) provided at the opposite 
sides with two pairs of first and second pockets (231) (232) which 
correspond to said first and second recesses (133) (134). A reinforcing 
toe lining (21) provided at the front end with a plurality of fourth holes 
(211) which correspond to said second holes (221) is attached to the inner 
face of said vamp section (22) by means of seaming and gluing to form a 
bag (which is not shown). 
A front cover (5) preferably made of steel provided around its periphery 
with a plurality of third holes (51) which correspond to said first, 
second and fourth holes (132) (221) (211) is positioned in and secured to 
said bag formed between said vamp section (22) and said toe lining (21). 
A facing (3) provided along the inner margins with a plurality of eyelets 
(31) through which a lace (32) (FIG. 2) may pass partly overlaps said side 
portions (23) and extends to the vamp section (22) of said shoe face (2) 
to provide a flexible adjustment for the tightness or looseness of the 
joint girth of the wearer, and a pair of fixing laces (33) are 
respectively anchored on the opposite sides of said facing (3). 
A protecting cover (4) provided on the opposite sides with two pairs of 
first and second legs (41) (42) which correspond to said first and second 
pockets (231) (232) overlays said facing (3) and said protecting cover (4) 
is further provided with two properly spaced apertures (43) through which 
said fixing laces (33) may pass to fix said protecting cover (4) in 
position. 
An insole (6) provided with a front wall (61) is positioned on the top of 
said outer sole (13) of said sole (1) to comfort the wearer's toes. 
In assembling, the front cover (5) is positioned into the bag which is 
formed between said vamp section (22) and said toe lining (21) and secured 
therein in such a manner that said front cover (5) is firstly glued to 
said vamp section (22) and toe lining (21) and then a plurality of 
rivetting members (52) which correspond to the third holes (51) of said 
front cover (5) are passed in sequence through said first (132), second 
(221), third (51), fourth holes (211) and rivetted thereon to provide a 
reinforced attachment for said front cover (5). 
Said shoe face (2) is attached to the fixing wall (131) of said outer sole 
(13) of said sole (1) in commonly used techniques, for example, by means 
of seaming, and a lace (32) passing through the eyelets (31) of said 
facing (3) may be properly tied thereover. 
An insole (6) is positioned on the outer sole (13) of said sole (1) with 
its front wall (61) against the rivetting members (52) to prevent the 
wearer's toes from directly contacting said rivetting members (52) hence 
to make the wearer's toes more comfortable. 
A protecting cover (4) is located on the top of said facing (3) in such a 
manner that the first and second legs (41) (42) thereof are respectively 
inserted into the first and second pockets (23) (232) of said side 
portions (23) and supported on the first and second recesses (133) (134) 
of said outer sole (13). It is noted that the protecting cover (4) instead 
of closely contacting the instep of the wearer's foot, keeps a proper 
distance from said instep thereof by means of the first and second legs 
(41) (42) respectively supported on the first and second recesses (133) 
(134) of said outer sole (13), hence said protecting cover (4) to the 
instep of the wearer's foot is similar to the safety helmet to the 
wearer's head, thus it may provide a better and reliable protection to the 
wearer's foot. After said protecting cover (4) has been properly disposed 
on above-noted position, the fixing laces (33) may pass through the 
apertures (43) of the protecting cover (4) and be properly tied over said 
protecting cover (4). 
In use, the protecting cover (4) originally is taken away from the safety 
shoe (10) as shown in FIG. 2, and when the wearer's foot is placed within 
the shoe (10), said lace (32) may be tightly tied over the facing (3) to 
prevent the wearer's foot from sliding out said shoe (10). Then, as shown 
in FIG. 1 the protecting cover (4) is properly located on the top of said 
facing (3) in above-mentioned way and keeps a proper distance from there. 
Said fixing laces (33) passing the apertures (43) thereof are tightly tied 
over said protecting cover (4) and fix said protecting cover (4) in 
position. Now, the wearer's foot may be under a better and reliable 
protection. 
Conclusively, a safety shoe (10) according to the present invention is 
provided on the vamp section (22) with a front cover (5) and on the facing 
(3) with a protecting cover (4) to provide a complete protection for the 
toes and instep of the wearer's foot. Furthermore, since the sole (1) of 
the safety shoe (10) comprises a steel plate (12) provided at the front 
end with a plurality of slots (121), it may increase the flexibility of 
the sole (1) to make the wearer's foot easily bent and hence to be more 
suitable for climbing up to a height during his work, and since the sole 
(1) of the safety shoe (10) is a tennis shoe type sole, it will prevent 
the rolling objects from easily rolling up to the instep of the wearer's 
foot hence can provide a better protection for the wearer's foot. 
In addition, the safety shoe (10) is of the type which is similar to the 
structure and function of a sport shoe hence it is more comfortable for 
the wearer's foot in contrast to the prior art of the leather shoe type.
