Description
The present invention relates to an ice skate guard comprising one or more parts having a channel in which an ice skate blade is intended to be détachably held.
A great number of different skate guards have been developed and used and the designs thereof have been adapted to several different types of skate blades. Conventional guards of one type consist of elastic rubber blocks each having a channel closed at both ends by substantially vertical walls.
A skate blade is detachably held in the channel by means of said walls which press against both ends of the blade due to the elasticity of the rubber material. A developed version of this guard consists of a non-elastic material and is lacking the substantially vertical rear wall but is provided with an elastic loop which is moved to surround the skate blade behind the rear column-shaped element connecting the blade to the skate shoe whereupon the guard is moved forwards against the action of the loop force until the substantially vertical front wall on the guard can be moved upwards to hold the tip of the blade.
A similar conventional guard consists of a wood block having a channel for receiving the blade and a yoke in the fro~t end of the block preventing the blade from being moved forwards and upwards. The rear portion of the blade is prevented from being moved upwardly in relation to the block by means of a springing clamp which is attached to the block approximately at the center of one of the long sides thereof and which is rotatable to a clamplng position where it partially surrounds the upper enlarged edge of the blade between the two column-shaped elements connec-ting the blade to the shoe.
The above described guards and other known guards suffer from certain disadvantages. The most common disadvan-tage is that the elastic material of the guard and~or the clamping means (the loop, for instance) will break after having been used a number of times. Another disadvantage is that one and the same guard cannot be used for skates the blades and/
or members connecting blades and shoes having different shapes.
Other disadvantages are that each guard can be used for a very limited number of skate sizes only and that the guard is not firmly retained on the skate when it is subjected to heavy stresses.
The present invention provides an ice skate guard which removes the above described disadvantages.
According to the present invention there is provided a guard for the blade of an ice skate comprising: a first elongat-ed part having a channel extending longitudinally thereof to receive the blade partially therein, said part at one end also having a recess opening longitudinally into said channel, said recess having an inwardly-upwardly inclined wall to form a socket for receiving one end of a skate blade, a second elongated part having a channel extending longitudinally thereof to receive the blade partially therein, said parts fitting telescopically one within the other and having a combined length greater than that of the skate blade, means for fixedly securing said parts in various relative positions of adjustment to accommodate blades of different sizes, and a leaf spring element fixedly secured to the free end of one of said parts and extending laterally in a direction toward a skate whose blade is to be received in said channel, the free end of said leaf spring element being formed to provide ~S~9l36~
an inwardly - upwardly inclined surface to engage and retain the remaining end of a skate blade within the channel and an inwardly-downwardly inclined surface serving as a cam permitting the downward force of the tip of a skate blade temporarily to displace said leaf spring element and subsequently secure the guard releasably to the skate blade.
In one embodiment of the present invention the means for securing said parts in various positions of adjustment permits adjustment in increments of fixed length and also in increments of varying length.
In another embodiment of the present invention the leaf spring element is at its free end formed with a manual grasping surface for deflecting the same and releasing the guard from the skate blade.
The greatest advantages with the invention are that the guard is firmly retained on the skate also when it is sub-jected to heavy stresses, that the guard easily can be mounted and removed, that the guard is robust and durable and that one and the same guard can be adjusted to be used for a great number of different skate sizes and also can be used for skates having different blade shapes and different shapes of the elements connecting the blades with the skate shoes.
The present invention will be further illustrated by way of the accompanying drawings in which:
Figure 1 is a perspective view - seen obliquely from above and from the front - of an ice skate guard in accordance with the invention, and - 2a -61C~
Figure 2 is a perspective view - seen obliquely from below and from behind - of the skate guard shown in Figure 1.
As is shown in Figures 1 and 2 the ice skate guard in accordance with the invention comprises two main parts, i.e., one front part 1 and one rear part 2, each one manufactured in one piece of hard plastic material. The rear part 2 has a back wall 3 inclining upwardly-forwardly and limiting the back-ward and upward movement of a skate blade 4 (shown by dash-dotted lines) out from a channel which is formed by an upwardly open relatively short groove 5 in a thickened rear portion of the part 2 and an upwardly open relatively long groove 6 in the part 1. These grooves are aligned. The wall 3 is relatively high to increase safe holding of the guard on the blade 4 and to give the guard sufficient stability.
The part 2 has a paralleltrapezoidal cross section with the short parallel top side open. The rear portion of the part 1 has a corresponding section and fits in the part 2 and is telescopically displaceable within the latter to shorten or lengthen the distance between the wall 3 and the front end of the front part 1 in order to adjust the guard to the desired skate blade length. Due to the trapezoidal section of the parts l and 2 the part 1 cannot be removed from the part 2 in any other way than by telescopically pulling the part 1 out from the part 2. The parts 1 and 2 may be locked to each other in anyone of a plurality of desired positions. To this end a number of holes 7 has been formed in both side walls of the part 1 and four slits 8 have been formed in both side walls of part 2.
The slits are on the same level as the holes 7. Four screws 9 are insertable in the slits 8 and screwed into opposite holes 7 after the desired guard length 9~
has been set. Due to the shor-t distance between adjacent holes 7 and the length of the slits an in~initely variable adjusting posæibility is obtained. A~-ter screwing, the par-t 1 is ~irmly anchored to the part 2.
The ~ront end o~ the part 1 i9 provided with an oblique forwardly-upwardly projecting cur~ed surface 10 on which is screwed or irl another way at-tached one leg 11 of a substantially S-formed tongue 12 manufactured from a ~lexible, wear resistant plastic matexial. 'rhe leg 11 is relatively long and extends along a portion o~ the underside of the part 1 in ordar to ensure a firm attachment o~ the tongue 12. ~he leg 11 transcends into an intermediate por-tion 13 bulging in a direotion towards -the part 2.
'L'he portion 13 transcends into a free leg l4 projecting ~orwardly past a toe-cap '~ on an ice skate shoe.
An-ti-slipping means 15 and 16 are attached to the bottom surface of the leg 11 and to the rear bottom surface on the part 2.
'rhese means increase the friction between the guard and the ground v~hen the skater is walking on his skates with the guards on.
Vlhen the guurd shall be mounted on a skate it is placed on the ground with the grooves directed upwardly whereupon the rear portion of the skate blade 4 is inserted in the groove 5 and is pressed backwards against the wall 3. ~his position is shovrn by means of dash-do-tted lines in ~igure 1. Then the front curved tip S
of the blade is forced downwardly ~rom the position shown in Figure 1 to engage the tongue 12. ~he intermediate portion 13 and the leg 14 will be pressed for~ardly against the action of the spring ~orce in the plastic material until the tip of the blade 4 has passed the portion 13 and this portion has come into contact with the forward upwardly-ba¢kwardly inclining portion of the clement 17 whioh connects the blade 4 with the schematically ~hown skate shoe. After the tip of the blade has pa~sed -the portion 13 ~1598~
the blaae 4 is situated in both grooves 5 and 6 and is held in this position by the tongue 12 engaging the element 17.
In the applied position of -the guard the bottom sur~aces of the element 17(on ea¢h side o~ the blade 4) are resting on those top ~url~aces of the parts 1 and 2 havingr the grooves 6 and 5. 'I'his is so because the height of the blade 4, i.e. the vertical distance between the sharp edge of the blade and the bottom ~urfaces o~ the element 17~ is less than the depth o~ the grooveq 5 and 6. In this manner is prevented that the sharp edge o~ the blade contacts and wears the bottoms of the grooves.
In order to make the alignment of the blade 4 easier be~ore it is in~erted in the groove 6 suitable guiding means (not shown) holding the blade centrally in relation -to the tongue 12 may be arranged on the upper surfaoe o~ the tongue between the portion 13 and the leg 14.
rrthe removal o~ the guard i9 performed by pre~sing a ~inger or an lce hockey stick~ ~or instance, against the upside o~ the free leg 14 so that the portion 13 will be ~orced ~orwardly whereupon the ~ront tip of the blade 4 and immediately therea~ter the whole blade ~ay be li~ted upwardly ~rom the guard.
Even -though only one embodiment o~ the invention has been described above and shown on the drawings it should be understood that the invention is not limited to this embodiment but only -to that which is stated in the pa-tent claims.
A great number of different skate guards have been developed and used and the designs thereof have been adapted to several different types of skate blades. Conventional guards of one type consist of elastic rubber blocks each having a channel closed at both ends by substantially vertical walls.
A skate blade is detachably held in the channel by means of said walls which press against both ends of the blade due to the elasticity of the rubber material. A developed version of this guard consists of a non-elastic material and is lacking the substantially vertical rear wall but is provided with an elastic loop which is moved to surround the skate blade behind the rear column-shaped element connecting the blade to the skate shoe whereupon the guard is moved forwards against the action of the loop force until the substantially vertical front wall on the guard can be moved upwards to hold the tip of the blade.
A similar conventional guard consists of a wood block having a channel for receiving the blade and a yoke in the fro~t end of the block preventing the blade from being moved forwards and upwards. The rear portion of the blade is prevented from being moved upwardly in relation to the block by means of a springing clamp which is attached to the block approximately at the center of one of the long sides thereof and which is rotatable to a clamplng position where it partially surrounds the upper enlarged edge of the blade between the two column-shaped elements connec-ting the blade to the shoe.

The present invention will be further illustrated by way of the accompanying drawings in which:
Figure 1 is a perspective view - seen obliquely from above and from the front - of an ice skate guard in accordance with the invention, and - 2a -61C~
Figure 2 is a perspective view - seen obliquely from below and from behind - of the skate guard shown in Figure 1.
As is shown in Figures 1 and 2 the ice skate guard in accordance with the invention comprises two main parts, i.e., one front part 1 and one rear part 2, each one manufactured in one piece of hard plastic material. The rear part 2 has a back wall 3 inclining upwardly-forwardly and limiting the back-ward and upward movement of a skate blade 4 (shown by dash-dotted lines) out from a channel which is formed by an upwardly open relatively short groove 5 in a thickened rear portion of the part 2 and an upwardly open relatively long groove 6 in the part 1. These grooves are aligned. The wall 3 is relatively high to increase safe holding of the guard on the blade 4 and to give the guard sufficient stability.
The part 2 has a paralleltrapezoidal cross section with the short parallel top side open. The rear portion of the part 1 has a corresponding section and fits in the part 2 and is telescopically displaceable within the latter to shorten or lengthen the distance between the wall 3 and the front end of the front part 1 in order to adjust the guard to the desired skate blade length. Due to the trapezoidal section of the parts l and 2 the part 1 cannot be removed from the part 2 in any other way than by telescopically pulling the part 1 out from the part 2. The parts 1 and 2 may be locked to each other in anyone of a plurality of desired positions. To this end a number of holes 7 has been formed in both side walls of the part 1 and four slits 8 have been formed in both side walls of part 2.
The slits are on the same level as the holes 7. Four screws 9 are insertable in the slits 8 and screwed into opposite holes 7 after the desired guard length 9~
has been set. Due to the shor-t distance between adjacent holes 7 and the length of the slits an in~initely variable adjusting posæibility is obtained. A~-ter screwing, the par-t 1 is ~irmly anchored to the part 2.
The ~ront end o~ the part 1 i9 provided with an oblique forwardly-upwardly projecting cur~ed surface 10 on which is screwed or irl another way at-tached one leg 11 of a substantially S-formed tongue 12 manufactured from a ~lexible, wear resistant plastic matexial. 'rhe leg 11 is relatively long and extends along a portion o~ the underside of the part 1 in ordar to ensure a firm attachment o~ the tongue 12. ~he leg 11 transcends into an intermediate por-tion 13 bulging in a direotion towards -the part 2.
'L'he portion 13 transcends into a free leg l4 projecting ~orwardly past a toe-cap '~ on an ice skate shoe.
An-ti-slipping means 15 and 16 are attached to the bottom surface of the leg 11 and to the rear bottom surface on the part 2.
'rhese means increase the friction between the guard and the ground v~hen the skater is walking on his skates with the guards on.
Vlhen the guurd shall be mounted on a skate it is placed on the ground with the grooves directed upwardly whereupon the rear portion of the skate blade 4 is inserted in the groove 5 and is pressed backwards against the wall 3. ~his position is shovrn by means of dash-do-tted lines in ~igure 1. Then the front curved tip S
of the blade is forced downwardly ~rom the position shown in Figure 1 to engage the tongue 12. ~he intermediate portion 13 and the leg 14 will be pressed for~ardly against the action of the spring ~orce in the plastic material until the tip of the blade 4 has passed the portion 13 and this portion has come into contact with the forward upwardly-ba¢kwardly inclining portion of the clement 17 whioh connects the blade 4 with the schematically ~hown skate shoe. After the tip of the blade has pa~sed -the portion 13 ~1598~
the blaae 4 is situated in both grooves 5 and 6 and is held in this position by the tongue 12 engaging the element 17.
In the applied position of -the guard the bottom sur~aces of the element 17(on ea¢h side o~ the blade 4) are resting on those top ~url~aces of the parts 1 and 2 havingr the grooves 6 and 5. 'I'his is so because the height of the blade 4, i.e. the vertical distance between the sharp edge of the blade and the bottom ~urfaces o~ the element 17~ is less than the depth o~ the grooveq 5 and 6. In this manner is prevented that the sharp edge o~ the blade contacts and wears the bottoms of the grooves.
In order to make the alignment of the blade 4 easier be~ore it is in~erted in the groove 6 suitable guiding means (not shown) holding the blade centrally in relation -to the tongue 12 may be arranged on the upper surfaoe o~ the tongue between the portion 13 and the leg 14.
rrthe removal o~ the guard i9 performed by pre~sing a ~inger or an lce hockey stick~ ~or instance, against the upside o~ the free leg 14 so that the portion 13 will be ~orced ~orwardly whereupon the ~ront tip of the blade 4 and immediately therea~ter the whole blade ~ay be li~ted upwardly ~rom the guard.
